CROSS RELATED APPLICATIONS
[0001] This new application is a continuation in part of U.S.
patent application Ser. No. 10/934,230 filed Sep. 3, 2004, which is
a continuation in part of U.S. patent application Ser. No.
10/797,252 filed Mar. 3, 2004 now abandon, which is a division of
U.S. Pat. No. 6,760,931 issued Aug. 8, 2002.
FIELD OF INVENTION
[0002] The present invention relates to a safety suction device for
a water vessel and incorporates improvements over patent
application Ser. No. 10/934,230 to Mattson et al.
BACKGROUND OF THE INVENTION
[0003] Whirlpool-type baths, spas and swimming pools have been
employed to treat discomfort resulting from strained muscles, joint
ailments and the like. More recently, such units have been used
increasingly as means of relaxing from the daily stresses of modern
life.
[0004] For as long as standard depth faceplates for suction
fittings has been around for whirlpool bathtubs, spas and swimming
pools, people have been trying to solve the long felt need to
prevent hair entrapment. The need to prevent hair entrapment in an
existing faceplate has been a persistent problem recognized by
those of ordinary skill in the art. The long-felt need of
preventing hair entrapment in an existing faceplate has not been
satisfied by another before the Mattson invention. There are
literally millions of existing faceplates possibly in need of a
retrofit solution. The water safety problem is still severe at
present. The 109th CONGRESS 2d Session introduced Bill S. 3718
recently. See http://www.theorator.com/bills109/s3718.html lasted
visited Sep. 9, 2007. It has been reported that hair entanglement
has been found by the CPSC to be the cause of every hair related
fatality. The Guidelines for Entrapment Hazards: March 2005 U.S.
Consumer Product Safety Commission Washington, D.C. 20207
Applicable Standards Appendix A found, "CPSC is aware of 43
incidents of hair entrapment or entanglement in pools, spas, and
hot tubs between January 1990 and August 2004. Twelve of the
incidents resulted in drowning deaths, as a result of hair becoming
entangled in the drain grates. Thirty-eight incidents occurred in
spas, including hot tubs, and five occurred in a pool. Typically,
these incidents involve females with long, fine hair, who are
underwater with their head near a suction outlet (drain). The water
flow into the drain sweeps the hair into and around the drain
cover, and the hair becomes entangled in and around holes and
protrusions on both sides of the cover. Entrapment occurs because
of the tangling and not necessarily because of strong suction
forces, although the suction forces initially draw the hair into
the drain cover." See
http://www.buyerschoiceinspections.com/Entrapment-Hazards.
[0005] Generally, as water is drawn in through a faceplate under
high velocity flow a number of hairs lay up against or across a
water flow through passage of a faceplate as seen in FIG. 13, 16,
17. Then generally, the hairs bend in two or about in half, under
suction force and go through at least two water flow through
passages. They then may twist or in some other manner get entrapped
in the faceplate and person cannot elevate their head above a
waterline and they drown. Hairs on peoples heads that are
candidates for entrappement are generally long consisting of
several hairs in bunches. Because of water suction draw, the hairs
in bunches (several), generally are drawn across the water flow
through passages of a faceplate.
[0006] Further, if the water flow through passages (channels) of
the faceplate are deep and the amount of hair in the channels is
sufficient, it may be difficult for a person to elevate their head
above water. These are examples of some ways hair entrapment
occurs.
[0007] There is evidence of efforts to solve the hair entrapment
problem by others. None solve the problem but the present invention
in an existing faceplate. One effort generally center on replacing
the existing faceplate with so called improved faceplates. The so
called "improved" faceplates do not address hair entrapment in an
existing faceplate and may not be considered a "real world"
solution even as an improvement. First and as discussed in more
detail later, these "improved faceplates" do not appear to have
water flow through openings configured to prevent hair from going
through them in a manner they do not get entrapped in the
faceplate. Second, it is known in the art that faceplates for
suction fittings for whirlpool bathtub, spas and swimming pools
generally go through independent testing. In the United States,
such testing and the testing criteria are currently set forth by an
ASME/ANSI STANDARD. The term `ASME/ANSI standard` means as defined
by Congress as a safety standard accredited by the American
National Standards Institute and published by the American Society
of Mechanical Engineers. See the 109th Congress 2d Session Bill S.
3718 mentioned above. Also see CPSC Document #5067 titled, Children
Drown and more are injured from Hair Entrapment in Drain Covers for
Spas, Hot Tubs, and Whirlpool Bathtubs: Safety Alert.
http://www.cpsc.gov/cpscpub/pubs/5067.html
[0008] As late as about the date of the present invention, standard
states that the suction fitting (combination faceplate and housing)
must be tested together to meet the standard. It is not known how
so call replacement faceplates when placed on field installed
housings would meet the combination testing criteria. One test
known in the art for suction fittings is the five pound hair pull
test. This test specifies a certain number and type of hairs are
attached to a dowel. The test further specifies that the hairs are
suspended in a certain manner to the front portion of the
faceplate. A certain time after water pump activation, the hairs
are removed under water suction force from the front of the
faceplate. If the force to remove the hairs is five pounds or less,
the suction fitting meets the five pound hair pull test. This test
is also only carried out a limited amount of times and does not
certify the faceplate or suction fitting prevents or inhibits hair
entrapment. This test does not include hair being subjected to all
the water flow through passages in the peripheral edge of the
faceplate. This may be why U.S. Pat. No. 5,799,339 to Perry et al.
and many other newer improved faceplates such as U.S. Pat. No.
6,588,029 to Mullens have a solid surface area in the front center
portion of the faceplate. This forces more water through the water
flow through openings in the peripheral edge or other water flow
through passages not in the center of the faceplate and disperses
(scatters loosely) water suction draw from the front center, thus,
aiding in passing the five pound hair pull test. None of these
replacement faceplates suggest that their water flow through
passages is configured to prevent hair from going through the
faceplate in a manner that they prevent hair entrapment, except for
certain embodiments of the present invention. Hence, no prior art
teaches a real solution, except for certain embodiments of the
present invention.
[0009] Liquid filters and water filters for whirlpool bathtubs,
spas and swimming pools teach away from the present invention with
respect to those of ordinary skill in the whirlpool bathtub, spa or
swimming pool art. Water filters known method of operation is to
filter debris, such as dirt and their method of operation are to
clog with accumulation of dirt. One testing criteria for spa and
swimming pool filters specify testing with a certain type of dirt.
Tests were conducted on a whirlpool bathtub suction fitting
faceplate using ISO12103-1A4 coarse test dirt by PTI Powder
Technology Inc, 1433 Ewing Ave. South Burnsville, Minn. 55306. The
test filter was taken from a spa cartridge filter and configured to
about the size of the existing faceplate. Water draw through the
existing faceplate and filter via a water pump was less than 140
gallons per minute. ISO12103-1 A 4 coarse test dirt was placed in a
tub and the tub ran for about a 10 minute bath cycle. The pressure
out the jets (water return fitting) indicated significant water
pressure drop. Small water filters in the art are generally known
to plug quick as their known operation is to trap dirt. Therefore,
they would not be a real world retrofit solution for hair
entrapment in an existing faceplate because they are designed to
clog and thus restrict water pressure out a water return fitting
such as a water jet. The term "specified test dirt" herein means
dirt having the following grain size distribution ranges in a
sample. 1 micron less than 0.06%-1.0%, 2 micron less than
2.2%-3.7%, 3 microns less than 4.2%-6.0%, 4 microns less than
6.2%-8.2%, 5 microns less than 8.0%-10.5%, 7 microns less than
12.0%-14.5%, 10 microns less than 17%-22.0%, 20 microns less than
32.0%-36.0%, 40 microns less than 57.0%-61.0%, 80-microns less than
87.5%-89.5%, 120 microns less than 97.0%-98.0%, 180 microns less
than 99.5%-100%, and 200 microns less than 100% of the total. The
term water saturated hair herein means hair that has been submersed
in water.
[0010] Some inventions claim to try and inhibit hair entrapment in
new whirlpool bathtubs, spas and swimming pool faceplates by
providing a cavitation system. These inventions while not a viable
retrofit solution are in fact not a solution at all. They all work
basically on the same premises. A certain segment of a faceplate is
block and an apparatus senses the blockage and cavitates the water
pump inhibiting water suction draw, or possibly cutting off water
suction draw through the faceplate. It is common sense that few
hairs would not block off even one water flow through passage
enough to cause cavitation yet could be enough to entrap hair.
"suction forces initially draw the hair into the drain cover." See
http://www.buyerschoiceinspections.com/Entrapment-Hazards.
[0011] In summary, there has been a long felt need to provide an
invention that will not decrease the water pressure out a return
fitting by more than thirty five percent and more preferably not
more than twenty percent and even more preferably not more than ten
percent and most preferably not more than five percent when over
one ounce of ISO12103-1 A 4 coarse test dirt is subjected to the
filter or cover (faceplate) or combination thereof, over at least 1
bath cycle, and more preferably over 20 bath cycles and even more
preferably over 50 bath cycles and most preferably over as many
consecutive bath cycles as desired, yet prevents hair entrapment in
the filter, or cover or faceplate or the existing faceplate or
combination thereof, providing a total solution to hair
entrapment.
[0012] Additionally, there has been a long felt need to prevent
hair from becoming entangled in a fill and drain whirlpool
bathtub's pump impeller. Hair, usually over 2 inches in length is
needed to get lodged in a pumps impeller. Matted hair may be a
breeding ground for bacteria growth in the enclosed plumbing system
after tub drain down and between electrical system activation. Over
time, months or years, the amount of hairs entangled in a pumps
impeller could be numbered in the hundreds or thousands. As
discussed above, the art has not solved this problem. One
embodiment of the present invention solves this problem without
significantly restricting water flow out a water return jet
fitting.
[0013] U.S. patent application Ser. No. 10/211,497 to Mattson et
al. is incorporated by reference herein in its entirety discloses a
suction filter.
[0014] U.S. patent application Ser. No. 10/934,230 to Mattson et
al. is incorporated by reference herein in its entirety discloses a
retrofit solution for hair entrapment in an existing faceplate.
[0015] U.S. Pat. No. 6,588,029 to Mullens discloses a replacement
cover having a "protective adapter for pool drains that
incorporates a universal mounting configuration providing simple
and effective installation to new and/or existing pool drains" and
a configuration to "provide an anti-vortex drain cover" for
"dispersing suction pressure and preventing a person's hair or
other body parts from becoming entangled and otherwise preventing
injury or death" such as U.S. Pat. No. 5,799,339 to Perry et al
disclose. The Mullins specifications further state "providing a
raised (i.e. non-planar) water flow inlet structure that is not
easily blocked by a human body thereby preventing a situation
wherein a person would be entrapped by suction" and "the recessed
segments thus result in a structure that is resistant to blockage".
Mattson provisional No. 60/185,528 filed Feb. 28, 2000 provides a
raised faceplate as does other prior art inventions. Mullins does
not teach or fairly suggest that his water flow through passages is
configured to inhibit hair entrapment or teach or fairly suggest
how his water flow through openings are spaced, sized, or numbered
to restrain hair entrapment. In view of prior art, it appears
Mullins universal mounting configuration is the invention.
[0016] U.S. Pat. No. 6,066,253 issued May 23, 2000 to Idland et al.
Discloses a way to attach a round filter to a faceplate. It is
common sense from Idland's disclosure that his filter does not
prevent hair entrapped. Inland does not describe his filter
prevents hair entrapment and that it would not significantly reduce
water flow out a return fitting "total solution". Idland does not
disclose that his filter water flow through openings are configured
so hair would not go through the filter in a manner that the hair
would become entrapped in the existing faceplate or in his
perforated filter core. From Inland's disclosed "attachment means"
(the invention) the filter must stick out into a tub providing an
area for hair to wrap around the filter and become entangled.
Inlands flange appears to cover a portion of the faceplate front
opening and thus would restrict water flow. Idland does not suggest
the filter's method of operation would not restrict water flow out
a jet when dirt is introduced as normal water filters operate.
[0017] U.S. Pat. No. 5,799,339 to Perry et al. teaches reducing
water vortex to help reduce the chance of hair entrapment with a
"guide vane".
SUMMARY OF THE INVENTION
[0018] The main aspect of one embodiment of the present invention
is to provide a complete solution to hair entrapment in an existing
suction fitting faceplate.
[0019] Another aspect of one embodiment of the present invention is
to provide a retrofitable solution to prevent water saturated hair
on a person's head from getting entangled around an existing
faceplate and entrapped in an existing suction fitting faceplate
for a whirlpool bathtub, spa or swimming pool.
[0020] Another aspect of one embodiment of the present invention is
to provide a retrofitable solution to prevent water saturated hair
on a person's head and body part from entrapment in an existing
suction fitting faceplate for a whirlpool bathtub, spa or swimming
pool.
[0021] Another aspect of one embodiment of the present invention is
to provide a suction fitting that will not permit water saturated
hair on a person's head to bend and go through the cover or filter
or combination thereof in a manner that it gets entrapped in the
cover.
[0022] Another aspect of one embodiment of the present invention is
to provide a certain number of water flow through passages per
square inch that are evenly spaced and sized to prevent, or
restrain, or inhibit hair entrapment.
[0023] Another aspect of one embodiment of the present invention is
to provide a filter made of a material having at least a percentage
or more preferably three percent or more preferably eight percent
chromium, molybdenum or other material for safety for the special
environment of a spa, whirlpool bathtub or swimming pool.
[0024] Another aspect of one embodiment of the present invention is
to provide a cover or filter media that prevents hair from wrapping
around an existing faceplate and becoming entangled or entrapped
and the cover or the filter media is easily removable from the
existing faceplate with less than 15 pounds pressure.
[0025] Another aspect of one embodiment of the present invention is
to configure a cover or filter media over an existing faceplate in
a manner to inhibit, or restrain, or prevent hair from entangling
around or causing entrapment around a portion of the cover or
filter media that extends from the front surface of the existing
faceplate into a tub.
[0026] Another aspect of one embodiment of the present invention is
to prevent or inhibit the amount of water saturated hairs of a
specified length from getting entangled in a water pumps impeller
or laying in plumbing piping between usages. Current faceplates
have water flow through openings sized that hair may go through
them of such length that they get entrapped in the impeller. Hair
helps to hold a growth of a microorganism in a plumbing system
between system usages. See prior art submitted entitled Hair in
Pump Circa 2005.
[0027] Since no one has ever marketed a retrofit cover or filter
media that solves the hair entrapment problem in existing
faceplates, one aspect of the present invention is to provide
packaging to efficiently market one embodiment of the present
invention.
[0028] Another aspect of one embodiment of the present invention
provides means functioning to restrain, or inhibit, or prevent hair
entrapment around an existing faceplate (it goes over the existing
faceplate) and at the same time restrains, or inhibits, or prevents
hair entrapment in a portion of the invention that extends past the
front surface of the existing faceplate into a tub, and restrains,
or inhibits, or prevents hair entrapment in the water flow through
passages of the existing faceplate and allows a specified test dirt
to pass through the invention over multiple usages without
significantly restricting the water flow out a water return
fitting.
[0029] Other aspects of embodiments of the present invention will
appear from the following description and appended claims,
reference being made to the accompanying drawings forming a part of
this specification wherein like reference characters designate
corresponding parts in the several views.

DETAILED DESCRIPTION OF THE DRAWINGS
[0052] Referring first to FIGS. 1 and 2. FIG. 1 is an example of
one embodiment of a water vessel assembly 1 having a tub 6 and the
tub having tub wall 6A and output jets 75 (water return fitting).
The water vessel is shown by way of example and not limitation. In
one embodiment of the present invention suction fitting 31 draws
water from in a tub into suction line 4 and into the pump 3.
Suction fitting 31 Pump 3 pumps water through return line 5 into
through jets 75 and into tub 6. In one embodiment of the present
invention suction fitting 31 has existing faceplate 14 (not shown).
In one embodiment of the present invention suction line 4 is sloped
upwards from suction fitting 31 to water pump 3 to provide
efficient water drainage from pump 3 to suction fitting 31. Jets 75
and suction fitting 31 are shown by way of example and not
limitation. Jets 75 in one embodiment of the present invention are
meant to illustrate one type of a water return fitting. All water
return fittings are envisioned by the present invention and fall
into the scope of the present invention. Water vessel assembly 1 is
shown by way of example and not limitation as certain embodiments
of the present invention works on all forms of water vessels and
other types of systems. In one embodiment of the present invention
at least one jet 75 has filter media 9. In one embodiment of the
present invention filter media 9 is configured to jet 75 as in the
same fashion as to an existing faceplate 14 shown herein. In one
embodiment of the present invention filter media 9 is configured to
cover a nozzle of jet 75 (not shown). The present invention
envisions all ways to attach filter media 9 to a segment of jet 75
and all ways are envisioned by the present invention. In one
embodiment of the present invention filter media 9 inhibits or
reduces the chance of a long hair two inches in length or the like
from going through jet 75 from tub 6 into the outlet water pipe 5.
In one embodiment of the present invention filter 9 is configured
to restrict jet 75 less than 10% and more preferably less than 5%.
The various configurations of filter media 9 to accomplish this
goal is described with respect to filter media 9 for hair safety
herein. Referring to FIG. 2 shows one embodiment of safety assembly
1 having cover 2. One embodiment of cover 2 is shown having front
water flow through passage(s) 8 and side water flow through
passage(s) 7 and lower drainage water flow through passage(s) 60.
Safety assembly 1 is shown by way of example and not limitation as
safety assembly one is envisioned to have numerous configurations
and all configurations are envisioned by the present invention and
fall into the scope of the present invention. Existing faceplate 14
is generally attached to suction fitting 31 on tub 6. Existing
faceplate 14 is shown only by way of example and not limitation and
is meant to show one type of an existing faceplate. The present
invention is capable of being configured to fit other existing
faceplates. In one embodiment of the present invention optional
chemical dispenser 3A is attached in some fashion or intergraded in
some fashion with cover 2. In one embodiment of the present
invention chemical dispenser 3A has one or more water flow through
openings 4. In one embodiment of the present invention a velcro
material 15A secures cover 2 over existing faceplate 14 to velcro
material 15. In one embodiment of the present invention velcro
material 15B secures filter media 9 over existing faceplate 14 or
some other existing faceplate (not shown). All ways of securing
cover 2 over existing faceplate 14 until a user or person desires
to remove cover 2 is envisioned by the present invention and fall
into the scope of the present invention. All attachment ways herein
are shown by way of example and not limitation. Existing faceplate
14 is a component or segment of a suction fitting and generally
extends into a tub. In one embodiment of the present invention
filter 9 resides between cover 2 and existing faceplate 14. In one
embodiment of the present invention the filter 9 provides a barrier
to prevent or inhibit hair 19 from going through filter 9 in manner
to become entrapped in water flow through passages 16 of existing
faceplate 14 or any and all water flow through passages in a front
section and peripheral edge section of an existing faceplate. This
is considered the best mode though other embodiments are important.
In one embodiment of the present invention existing faceplate 14 is
shown without limitation and is meant only to illustrate a standard
existing faceplate. In one embodiment of the present invention
segment B of filter media 9 fits between existing faceplate 14 and
a suction housing (not shown) at position G. This is one example
how filter media 9 is configured to stay over an existing faceplate
until a person removes it. In one embodiment of the present
invention an additional filter media 9A is utilized to provide an
extra measure of safety or durability to prevent or inhibit hair
entrapment in an existing faceplate. In one embodiment of the
present invention at least some of the water flow through passages
of filter media 9A are offset from at least some of the water flow
through passages in filter media 9. In one embodiment of the
present invention filter media 9A has some or all the attributes of
filter media 9. In one embodiment of the present invention filter
media 9 is made out of a material that stretches. In one embodiment
of the present invention filter media 9 is configured and filter
media 9A is configured having a space between them small enough to
inhibit or prevent a hair from going through filter media 9 and
becoming twisted behind filter media 9 and filter media 9A. In one
embodiment of the present invention as water moves through the
filter media 9 in direction WF filter media 9 water pore openings
(water flow through passages) in one embodiment of the present
invention or weave pattern (water flow through passages) in one
embodiment of the present invention or, knit pattern (water flow
through passages) in one embodiment the present invention expands
to not decrease water pressure out a return water fitting by less
than 35% and more preferably by less than 15% yet prevents or
inhibits hair 19 or hairs in one embodiment of the present
invention from going through filter media 9 in a manner that they
get entrapped in existing faceplate 14. In other words, in one
embodiment of the present invention filter media 9 disrupts hair
flow through filter media 9. In one embodiment of the present
invention filter media 9 or filter media 9A are about the size of
an existing faceplate they cover. About the size means within 40
square inches of the surface area of the existing faceplate. This
provides for a very small filter. Small water filters in the art
are known to filter dirt, such as test dirt. Normal water filters
in the art for spas, swimming pool and whirlpool bathtubs in the
United States may be tested using ISO12103-1A4 coarse test dirt.
Using one ounce of this test dirt going through a standard water
filter at high velocity water flow associated with a spa, whirlpool
bathtub, or swimming pool, the small filter plugs rapidly. In one
embodiment of the present invention as the test dirt starts to fill
the water flow through passage of the filter, they expand so the
filter will not restrict the water flow out a water return fitting
by less than 35% and more preferably less than 15% even when
several ounces of test dirt are run through the filter over several
bath cycles. Expansion of the water flow through openings to reduce
water restriction out a water return fitting is shown by way of
example and not limitation. The present invention envisions all
ways and means functioning to configure filter media 9 to reduce
water restriction out a water return fitting and all ways fall into
the scope of the present invention. There are other ways to
configure filter 9 to prevent or inhibit hair from going through
the filter in a manner it becomes entrapped in an existing
faceplate while not decreasing the water pressure out a water
return fitting and all ways are envisioned by the present invention
and fall into the scope of the present invention. One embodiment of
the present invention's filter media 9 utilizes a nylon type
material. The term prevents any hair entrapment in a pump impeller
herein means a hair at least 2 inches long will not wrap around the
pumps impeller. The term prevent any hair from going through the
filter media in a manner to get entangled in a water pump impeller
herein means a hair measuring at least 2 inches in length will not
wrap around the pumps impeller. In one embodiment of the present
invention as dirt and the like moves through the nylon fibers (not
shown), the nylon fibers may act like little knives cutting up the
dirt providing less than 35% water restriction out a water return
fitting yet attracting hair(s) in a manner that it will not pass
through the filter in a manner that it becomes entrapped in an
existing faceplate. The present invention envisions using all
material that accomplishes the same goal and all material fall into
the scope of the present invention. In one embodiment of the
present invention filter 9 is integrated with perforated cover 2 or
perforated cover 21 or existing faceplate 14. In one embodiment of
the present invention filter media 9 is integrated in the
manufacturing process with perforated cover 2 or perforated cover
21 (not shown) or existing faceplate 14. In one embodiment cover 2
or cover 21 is made by an injection molding process or some other
process and filter media 9 is integrated in the injection molding
manufacturing process with perforated cover 2 or perforated cover
21. All ways and configurations to integrate filter media 9 are
envisioned by the present invention and fall into the scope of the
present invention. In one embodiment of the present invention a
chemical 34 resides between filter media 9 and filter media 9A. In
one embodiment of the present invention chemical 34 is sized and
configured to release a measured dose of at least 1 part per
million after mixing with water in a tub (not shown) for about a
given tub gallon capacity. "About" means within 25% plus or minus a
suggested water capacity. In one embodiment of the present
invention filter media 9 or filter media 9A are disposable. In one
embodiment of the present invention filter media 9 or filter media
9A are disposable after chemical 34 is spent or in one embodiment
of the present invention over 50% used. In one embodiment of the
present invention filter media 9 and filter media 9A are configured
to provide that chemical 34 is replenishable. In one embodiment of
the present invention filter media 9 is made of a material such as
nylon that lasts at least 90 bath cycles and more preferably at
least 180 bath cycles and more preferably at least 360 bath cycles
before needing replacement when over 35 gallons per minute or over
70 gallons of water per minute is flow through the filter each bath
cycle or when at least one ounce of ISO12103-1A4 coarse test is
moving through the filter each bath cycle. Other materials that
accomplish the same goal are envisioned by the present invention
and fall into the scope of the present invention. In one embodiment
of the present invention filter media 9 weighs less than 2 ounces
yet accomplishes the goals set forth herein for water restriction
and hair entrapment prevention. One embodiment of filter media 9A
has adjustment mechanism 63 or adjustment way to allow the filter
to fit more than one existing faceplate and stay over the existing
faceplate until a user desires to remove it from the existing
faceplate. Adjustment mechanism 63 or adjustment way is shown by
way of example and not limitation and the present invention
envisions all adjustment mechanisms and adjustment ways and all
fall into the scope of the present invention. In one embodiment of
the present invention a filter media 9 has a front surface 1A and a
rear surface 1B. In one embodiment of the present invention a
segment of the rear surface of the filter media 9 is configured for
direct or about direct abutment with an existing faceplate 14 of a
suction fitting. In one embodiment of the present invention filter
media 9 is configured for placement in parallel manner or about a
parallel manner to the cover and the faceplate so in one embodiment
of the present invention as to have same or about the same water
direction from the front of the water flow through passage to the
back of the existing faceplate. In one embodiment of the present
invention filter media 9 is configured to conform to about the
front surface of an existing faceplate. The present invention
envisions all means functioning and ways to place or keep filter
media 9 in a parallel manner to cover 2 or an existing faceplate 14
and all means and ways fall into the scope of the present
invention. In one embodiment of the present invention filter media
9 inhibits or prevents hair entrapment in the peripheral edge of
existing faceplate 14 or another existing faceplate. In one
embodiment filter media is configured to filter large debris such
as hair that provides a food source for bacteria growth in a closed
loop plumbing system. The term filters debris means only some large
debris and not all debris. In one embodiment of the present
invention filter media 9 is configured to go over existing
faceplate 14 in a manner that hair 19 on a persons head 20 cannot
become wrapped around filter media 9 under normal usage in a manner
that a person cannot remove it and it becomes entrapped. In one
embodiment of the present invention filter media 9 is configured to
existing faceplate 14, or another existing faceplate, so that any
portion extending into a tub is not sufficient that a person's hair
19 on their head 20 will not become entrapped on or around filter
media 9. In one embodiment of the present invention filter media 9
is configured having a knit pattern, or weave pattern that prevents
or inhibits hair 21A from bending in two as shown and going through
filter media 9 in a manner that the hair becomes entrapped in an
existing faceplate. In one embodiment of the present invention
filter media 9 is configured having a knit pattern, or weave
pattern that prevents or inhibits a hair 21A over 1 inch or more
preferably over 2 inches or more preferably over 3 inches or most
preferably over 4 inches in length from bending in two and going
through filter media 9 in a manner that hair 21A becomes entrapped
in an existing faceplates water flow through passage or passages.
In one embodiment of the present invention filter media 9 has a
water flow through passage knit pattern, or weave pattern that
helps to distribute a hair 19 across the pattern reducing water
suction draw preventing or inhibiting hair 19 on a persons head
over 1 inch or more preferably over 2 inches or more preferably
over 3 inches or most preferably over 4 inches in length from
bending in two as hair
21A is show and going through filter media 9 in a manner that the
hair becomes entrapped in an existing faceplate's water flow
through passage or passages. The present invention envisions adding
a sharp edge 37 to the faceplate. While this may provide a small
amount of extra safety, a sharp edge 37 may not be able to free all
entrapped hair as it would be difficult at best to cut through a
number of hairs in such a small water flow through passage. In
other words, there is not enough side to side cutting motion in the
small water flow through passage to provide a cutting surface large
enough to sever bunched hairs under all conditions. If the water
flow passages where configured to cut a large amount of bunched
hairs that may present other problems. It is sometimes difficult
for even a razor to sever a few hairs under these circumstances.
Filter media 9 as shown is configured in one embodiment of the
present invention to have about the same water flow direction
through the water flow through passages to the back of an existing
faceplate. This also encompasses the water flow through passages
may be offset 1 to 30 degrees. In one embodiment of the present
invention at least 1 and more preferably at least 50 and more
preferably all the water flow through passages have the same
diameter or have a diameter within 150 microns and more preferably
within 100 microns and more preferably at least 50 microns. In one
embodiment of the present invention the water at least 10 percent
and more preferably all the water flow through passages are evenly
spaced less than 200 microns and more preferably less than 100
microns apart. These configurations evens out the water pressure
across the water flow through passages allowing hair to lay up
against the front surface of the present invention. Another way to
visually illustrate the water restriction characteristics of one
embodiment of the present invention, one embodiment of the present
invention's filter media or cover is configured that when held in
front of and within six inches of an image a person having 20/20
vision can look through the filter media or cover and distinguish
what an image behind the filter or cover is. As an example if a
photograph of a dog were placed behind one embodiment of the
present invention a person could ascertain the photograph was a
dog. Of coarse the size of the filter or cover would need to be
several square inches for this demonstration. In one embodiment of
the present invention over 20% and more preferably over 50% and
most preferably 100% of the water flow through passages have a
diameter of over 20 microns and less than 275 microns and at least
20% and more preferably over 50% and most preferably all the water
flow through passages have a diameter of the same size or within 50
microns or most preferably within 10 microns of each other. While a
portion of a hair may extend through some of the embodiments of
present invention's filters and covers disclosed herein, the hairs
are restrained, or prevented, or inhibited from extending through
the filters or covers in the length, number and configuration
needed (manner) to become entrapped in an existing faceplate, or
the filter, or the cover, to degree a person cannot elevate their
head above a waterline. In one embodiment of the present invention
the water flow through passages are configured to restrain, or
inhibit, or prevent 15 hairs and more preferably less Man 15 hairs
and more preferably less than 14 hairs and more preferably less
than 13 hairs and more preferably less than 12 hairs and more
preferably less than 11 hairs and more preferably less than 10
hairs and more preferably less than 9 hairs and more preferably
less than 8 hairs and more preferably less than 7 hairs and more
preferably less than 6 and more preferably less than 5 hairs and
most preferably less than 4 hairs from going through the water flow
through passages in a manner they become entrapped and a person
cannot elevate their head above a waterline. In one embodiment of
the present invention cover 2 is configured to an existing
faceplate to be removed without a tool. In one embodiment of the
present invention cover 2 is configured to an existing faceplate to
be removed with less than 5 pounds pressure. In the one embodiment
of the present invention this is accomplished by the water flow
through openings of the cover having the same or larger diameter
than the existing faceplate. Hence, there is little water suction
draw through cover 2 allowing for easy removal. This provides that
if hair becomes entangled in the cover in one embodiment of the
present invention, cover 2 is easily removed. In one embodiment of
the present invention all the water flow through openings in cover
2 have a surface area larger than all the water flow through
passages in an existing faceplate. This also provides for easy
removal of less than 15 pounds or more preferably less than 5
pounds force to remove cover 2 from an existing faceplate when the
high velocity water is moving through cover 2. In one embodiment of
the present invention filter media 9 is for easy removal of less
than 15 pounds or more preferably less than 5 pounds force to from
over an existing faceplate when high flow water pressure is moving
through the filter media. There is no prior art for a water suction
fitting having a second cover configured over an existing faceplate
that is designed for safety reasons to pop out with minimal force,
except for the present invention. U.S. Pat. No. 6,066,253 issued
May 23, 2000 to Idland et al. discloses a cover where the a portion
of the cover covers the water flow through openings in the existing
faceplate and the Inland flange over the water flow through
openings in the existing faceplate likely would act as a suction to
make it difficult for a user to remove when a water pump is
activated.
[0053] Referring next to FIG. 3 shows one embodiment of cover 2
having front water flow through passages 8, side water flow through
passages 7 and drainage water flow through passages 60. In one
embodiment of the present invention cover 2 is configured having a
handle 30 for ease of removing cover 2 from over existing faceplate
14. The handle is shown by way of example and not limitation and
the present invention envisions all means functioning to keep cover
2 or filter media 9 over an existing faceplate or means functioning
to remove cover 2 or filter media 9 from an existing faceplate and
all means and ways fall into the scope of the present invention. In
one embodiment of the present invention filter 9 is configured to
reside between cover 2 and cover 3. Cover 2 and cover 3 in one
embodiment of the present invention is configured to cover existing
faceplate 14 or another existing faceplate. One Embodiment of cover
3 like one embodiment of cover 2 described above has in one
embodiment of the present invention means functioning to keep cover
3 over an existing faceplate until a person removes it. All means
functioning are envisioned by the present invention and fall into
the scope of the present invention. In one embodiment of the
present invention water flow passage way 32 are positioned or
configured throughout surface 33 of filter media 9. In one
embodiment of the present invention filter media 9 is configured to
cover all water flow through passages 16 on existing faceplate 14.
In one embodiment of the present invention filter 9 abuts the front
surface of existing faceplate 14. In one embodiment of the present
invention filter media 9 is configured to conform to the shape or
about the shape of existing faceplate 14 or another existing
faceplate or faceplate (not shown). In one embodiment of the
present invention cover 3 is configured having tits 4 that secure
cover 3 to cover 2 until a person removes it. All means functioning
and ways to secure cover 3 to cover 2 are envisioned by the present
invention and fall into the scope of the present invention. In one
embodiment of the present invention at least 10 of the water flow
through passages 7, or 8 or 60 and more preferable most or all are
configured to prevent or inhibit hair entrapment in an existing
faceplate and restrict water flow out a return water fitting by
less than 35% and more preferably less than 15%. In other words, in
one embodiment of the present invention cover 2 has the same or at
least some of the attributes or configuration as filter media 9. In
one embodiment of the present invention filter media 9 is
configured having rubber band type material 17 integrated with
filter media 9 in the manufacturing process. In one embodiment of
the present invention the rubber band type material 17 is a
separate part from filter media 9. In one embodiment of the present
invention the rubber band (elastic) type material helps keep filter
9 over an existing faceplate until a user desires removes it. In
one embodiment of the present invention the inside of filter media
9 is configured having at least a segment having an adhesive 18 to
keep filter media 9 over an existing faceplate until a user to
remove it from the existing faceplate. In one embodiment of the
present invention the adhesive is applied in a concentration so
filter media 9 does not tear when removed from an existing
faceplate. In one embodiment of the present invention filter media
9 is configured to fit snuggly over an existing faceplate to keep
it over the existing faceplate until a user or person remove it. In
one embodiment of the present invention cover 2 or cover 21 (not
shown) is configured to fit snuggly over an existing faceplate to
keep it over the existing faceplate until a user or person remove
it. In one embodiment of the present invention the majority of
water flow through passages 7 and 8 are sized smaller than the
water flow through passages on existing faceplate 14. In one
embodiment of the present invention at least some of the water flow
through passages 7A, 8A, and 60A are larger than the at least some
of the water flow through passages 7 and 8 and 60. In one
embodiment of the present invention this provides a better water
flow rate through the existing faceplate for a given vacuum water
pressure on an inlet water line 4 shown in FIG. 1. Also, it reduces
water restriction out a return water fitting. One embodiment of the
present invention is configured to prevent a hair the size of over
2 inches in length from entering the closed loop plumbing system
and getting entangled in pump 3 shown in FIG. 1 while restricting
water flow pressure out a return fitting by less than 35, or 20 or
15 or 5 percent. In one embodiment of the present invention cover 2
or 3 is configured to be flexible. In other words it bends or
flexes in ones hand pressure. Because the cover is a safety cover,
in one embodiment of the present invention the cover 2 or 3 is made
of a material that a person cannot exert enough hand pressure to
break it. In one embodiment of the present invention the cover is
configured having no sharp edges to cut or otherwise harm a child
playing with it aged less than 5 years old. In one embodiment of
the present invention filter media 9 is constructed with about flat
peripheral edge surface 33 that is about the same configuration as
the flat peripheral side surface of existing faceplate 14 and
configured having a front surface 37A that is about the same as the
front surface 36 of an existing faceplate before the filter is
slipped over the existing faceplate. In one embodiment of the
present invention side surface 37 of existing faceplate 14 is about
parallel with side surface 37 C of cover 2 or about parallel with
surface 33 of filter media 9. In one embodiment of the present
invention filter media 9 or cover 2 or cover 3 is made from a stamp
mold process or cutting tool process. One embodiment of filter
media 9 has an attachment mechanism 40 secured to filter media 9 to
secure filter media 9 over an existing faceplate until a user
removes filter media 9 from an existing faceplate. In one
embodiment of the present invention removal of cover 2 or cover 3
or filter media 9 is facilitated without use of a tool. This is
defined as removal by a person's body part. In one embodiment of
the present invention cover 2 or cover 3 or cover 21 (not shown) or
filter media 9 is configured for removal from an existing faceplate
utilizing a tool. Tool is defined as a means of removal other than
a person's body part. The attachment mechanism is shown by way of
example and not limitation. The present invention envisions all
attachment mechanisms means and all fall into the scope of the
present invention. In one embodiment of the present invention
filter media 9 has a color shade of blue, or red, or black, or blue
or green, or another color to designate it has antimicrobial
properties. In one embodiment of the present invention cover 2 has
an indicator 38 so a user knows when it is time to replace cover 2
or filter media 9. The indicator 38 is shown by way of example and
not limitation. All indicators fall into the scope of the present
invention. In one embodiment of the present invention filter media
9 has an indicator 38 so a user knows when it is time to replace
filter media 9. Indicator 38 is a dyed portion of the filter media.
The dye is calibrated to release into water at a certain rate
during each bath cycle. The more bath cycles the more release of
dye which changes the color of Indicator 38. As the color reaches
about a desired shade, this indicates it is time to replace the
filter. The indicator 38 is shown by way of example and not
limitation. The present invention envisions all indicators and all
indicators fall into the scope of the present invention. The
indicator or means functioning could even be wording located on the
filter or in the filters packaging. In one embodiment of the
present invention cover 2 has a raised (radius) front surface 34.
In other words, faceplate position center C extends outward past
faceplate position D and E in one embodiment of the present
invention. In one embodiment of the present invention the filter
media 9 fibers 51 are made to absorb a certain amount of dirt or
water. In one embodiment of the present invention when filter media
9 in over existing faceplate 14, filter media 9 is configured to
not deflect more than one half of an inch when a load pressure
point of two hundred and fifty pounds in subject to the center S of
the front surface side of filter media 9. In one embodiment of the
present invention cover 2 or filter media 9 is configured having
one or more suction cup 39 to secure one or the other over an
existing faceplate until a user desires to remove one or the other.
The suction cup and location are shown by way of example and not
limitation. The present invention envisions all suction cups and
their locations and they all fall into the scope of the present
invention. In one embodiment of the present invention the covers
combined water flow through openings have a surface area for water
flow through larger than the total water flow through area in the
existing faceplate. This facilitates less water restriction out a
water return fitting. All means to keep the filter is direct
abutment or about direct abutment with the existing faceplate is
envisioned by the present invention and fall into the scope of the
present invention attached to the filter or by other means. In one
embodiment of the present invention filter water flow through
passages (pores) 32 stretches when water passes through them. In
one embodiment of the present invention filter pores 32, filters
some debris, then when the some debris builds up in pores 32, pores
32 stretches allowing at least some of the debris to move through
the filter media 9 and thus reduces pressure out a water return
outlet fitting (not shown). One embodiment of filter 9 has at least
a segment made of a layered or non layered weave pattern or knit
pattern 35. This pattern disrupts a hair from going through the
filter 9 in a manner that it gets entrapped in an existing
faceplate. In one embodiment of the present invention when hair
enters into the pattern 35 a user can remove the hair. In one
embodiment of the present invention filter media 9 is made of a
rigid material or semi rigid material. In one embodiment of the
present invention filter at least a segment of media 9 is made out
of non rigid material or a material that flexes. In one embodiment
of the present invention filter media 9 is configured to go over
existing faceplate 14 in a manner that hair on a persons head
cannot become wrapped around filter media 9 under normal usage. In
one embodiment of the present invention cover 2 or cover 3 or the
combination have a hole opening (not shown) to receive attachment
member 19. Attachment member 19 secures cover 2 or 3 or combination
thereof to suction housing is in FIG. 14. In one embodiment of the
present invention cover 2 or cover 3 has support ribbing or is
configured in same fashion when secured to suction housing 15 so
that it will not flex more than 3/4 inches or 1/2 inches when a
load pressure point of 250 pounds is subjected to center C. In one
embodiment of the present invention the ribbing is configured to be
a variation the ribbing found in Mattson Ser. No. 10/211,497 or
U.S. Pat. No. 5,799,339 to Perry et al, which is incorporated
herein by reference. The ribbing is shown by way of example and not
limitation as pertaining to the present invention. The present
invention envisions all ways to meet the 250 pound strength or pass
a 150 pound test and all ways fall into the scope of the present
invention. In one embodiment of the present invention filter media
9 is configured having a depth of less than four inches from
position X to position Y yet is configured to resist, or inhibit,
or prevent hair of a length over four inches from going through the
filter media in a manner it becomes entrapped in the filter media
or an existing faceplate. In one embodiment of the present
invention cover 2 has a depth of less than four inches from
position G to position H yet is configured to resist, or inhibit,
or prevent hair of a length over four inches from going through
cover 2 in a manner it becomes entrapped in cover 2 or an existing
faceplate. In other words, in one embodiment of the present
invention cover 2 or filter media 9 is configured to resist, or
inhibit, or prevent hair longer than the depth of the cover or
filter from entrapment. In one embodiment of the present invention
filter media 9 is configured to about the shape of existing
faceplate 14 and configure to about hold that shape when removed
from existing faceplate 14. One of ordinary skill in the art can
see from FIG. 3 that in one embodiment of the present invention
cover 2 fits over existing faceplate 14 in a manner that cover 2
only extends forward of the front surface 36 into a tub (not shown)
the width of the material used to make cover 2, generally less than
1/2 inch or less than 1/4 inch or less than 1/8 inch or less than
1/16 inch. Therefore, cover 2 in one embodiment of the present
invention is configured to an existing faceplate so hair is
inhibited, or prevented, from wrapping around a portion 90 of cover
2 that extends past the front surface 36 of the existing faceplate
into a tub cause entrapment in one embodiment of the present
invention and entanglement in one embodiment of the present
invention. As disclosed here, in one embodiment of the present
invention cover 2 is configured as one or more embodiments of
filter media 9. In one embodiment of the present invention at least
one but more preferably all the water flow through passages 7 in
the peripheral edge of cover 2 overlay at least one or more
preferably all the water flow through passages 16 in the peripheral
edge of existing faceplate 14. In one embodiment of the present
invention at least one water flow through passage 7 and more
preferably all the water flow through passages 7 have a diameter
larger than at least one of the water flow through passages 16 and
more preferably larger than all the water flow through passages 16.
This provides to help remove cover 2 from over existing faceplate
14 will less pressure providing extra safety. In one embodiment of
the present invention at least one and more preferably all the
water flow through passages 7 or 8 or 16 has a radius 70. This
helps for efficient water flow through cover 2 and thus provides
safety. In one embodiment of the present invention existing
faceplate 14 is adjacent to tub wall 6A.
[0054] FIG. 4 shows one embodiment of perforated cover 21 having
one or more water flow through passage(s) 10. In one embodiment of
the present invention cover 12 has an adjustment mechanism so cover
12 fits more than one size existing faceplate. The adjustment
mechanism 62 or adjustment way is shown by way of example and not
limitation and the present invention envisions all adjustment
mechanisms and means functioning to keep cover 12 over an existing
faceplate or suction housing (not shown) are envisioned and fall
into the scope of the present invention. In one embodiment of the
present invention filter media 9 is configured to cover 21 in the
manufacturing process. In one embodiment of the present invention
filter media 9 is another color or another shade of color than an
adjacent faceplate 14 (not shown) or cover 2 (not shown) or cover
21 to call attention to filter media 9. In one instance to call
attention, that filter media 9 is a safety feature, or overlays a
suction inlet. In one embodiment of the present invention cover 21
is sized to slip over an existing faceplate so it does not dislodge
from the existing faceplate completely until a user removes it. For
added safety, in one embodiment of the present invention cover 21
is made out of a material that flexes.
[0055] FIG. 5 shows a cutaway of a water flow passage way 16 in
existing faceplate 14. In one embodiment of the present invention
water filter media 9 is configured to extend into water flow
passage way 16 when high velocity water moves in direction WF. In
one embodiment of the present invention water filter media 9 has
antimicrobial properties. In one embodiment of the present
invention filter media 9 is configured in relationship to water
flow through passages 16 to extend into a water flow through
passage 16 at least 1/16.sup.th of an inch when water flow is
passing in direction WF.
[0056] FIG. 6 shows users head 26 entrapped under waterline WL.
Hair 19 and hair 18 are drawn through water flow passages 16 in
faceplate 14. Water generally vortexes behind the water flow
passages and the hair twist entrapping user's head under waterline
WL. One embodiment of the present invention such as but not limited
to filter media 9 reduces the water vortexing and inhibits or
prevents the hair from twisting and becoming entangled in existing
faceplate 14.
[0057] FIG. 7 shows filter media 9 having a water flow through
passage 60. Water flow through passage 60 is offset from water flow
through passage 50 in filter media 9A. This offset reducing the
chance of hair from getting entrapped in an existing faceplate. In
one embodiment of the present invention filter media 9 has at least
a segment of water flow through passages having a diameter over 25
microns and less than 200 microns and at least a segment of the
water flow through passages have a space between them of less than
100 microns and more preferably less than 50 microns. This provides
less water flow out restriction a water output fitting while
preventing, or inhibiting hairs from going through filter 9 media
in a manner that the hair gets entrapped in filter media 9 or an
existing faceplate. In one embodiment of the present invention at
least fifty percent of the water flow through passages in filter
media 9 or cover 2 (not shown) are spaced less than 100 microns
apart or more preferably less than 50 microns apart. In one
embodiment of the present invention water flow through passage 50
has a diameter less than the diameter of water flow through passage
60. In one embodiment of the present invention the space between
filter media 9 and filter 9A (between position A and B) is less
than the amount of space needed for hair 61 to twist behind filter
media 9 to the degree to cause entrapment. In other words, in one
embodiment of the present invention filter media 9A is positioned
too close to filter media 9 for hair to twist behind filter media 9
and get entrapped in filter media 9. The positioning to filter
media 9 and filter media 9A is shown by way of example and not
limitation. There are numerous ways to configure filter media 9 and
filter media 9A to accomplish this goal to inhibit or prevent hair
entrapment and all ways fall into the scope of the present
invention. As disclosed herein, filter media 9A and filter media 9
are configured to not significantly restrict water flow out a water
return fitting when test dirt is passing through them. Filter media
9 has as shown is configured in one embodiment of the present
invention to have about the same water flow direction through the
water flow through passages to the back of filter media 9A.
[0058] FIG. 8 is a cross sectional view of one embodiment of
retrofit filter media 9. Filter media 9 is shown having a
vertically raised portions 69. The raised portions inhibits a body
part 70 from getting entrapped in an existing faceplate that filter
media 9 covers. In one example, plastic channels 71 are utilized to
raise the filter media 9 in a manner to inhibit or prevent body
entrapment in an existing faceplate when high velocity water moves
in direction WF through existing faceplate 14. The raising of
filter media 9 is shown by way of example and not limitation as
there are numerous ways to raise filter media 9 to inhibit or
prevent body entrapment and all ways are envisioned by the present
invention and fall into the scope of the present invention. In one
embodiment of the present invention filter media 9 is configured
having a section 72. In this embodiment an existing faceplate is
removed and a part of section 72 fits between the existing
faceplate 14 and a suction housing 15 to keep filter media 9 over
existing faceplate 14. This securing means or method is shown by
way of example and not limitation. The present invention envisions
all means to secure filter media 9 over an existing faceplate until
a user removes it and all ways fall into the scope of the present
invention. In one embodiment filter media 9 has the same
configuration as cover 2 disclosed herein and is configured to
secure directly to suction housing 15 requiring a tool for removal.
From reading this entire disclosure one schooled in the art would
know how to accomplish this goal. In one embodiment of the present
invention channels 71 have water flow through openings 73. Channels
71 are also shown by way of example and not limitation as channels
71 are envisioned to have many configurations and all
configurations fall into the scope of the present invention. In one
embodiment of the present invention the raised portions 71 are
surrounded by filter media 9. No limitation is inferred for this
combination.
[0059] Referring next to FIGS. 8B and 9. FIG. 8B shows a section of
one embodiment of filter media 9 having eight water flow through
passages 50. The configuration of filter media 9 is shown only as
an illustration of how one embodiment of the present invention
operates. The operations shown is not limited as other embodiments
of the present invention achieve the same goal through different
operation. All operations are envisioned by the present invention
and fall into the scope of the present invention. As water is drawn
through the water flow through filter media 9, filter media 9
either flexes in direction P or at least a segment of filter media
9 moves in direction. In one embodiment of the present invention a
segment of filter media 9 moves into at least one water flow
through passage (not shown) of existing faceplate 14 in FIG. 9. As
hair 10 is drawn under high velocity water flow into water flow
through passage 52, the force of the water pressure in combination
with the flexing of the filter provides that the end segment B of
hair 10 lays up against fibers 51 of filter media 9 inhibiting or
preventing hair from going through filter media 9 in a manner that
it gets entrapped in existing faceplate 14. In one embodiment of
the present invention fibers 51 are micro fibers that help to
prevent hair 10 from going through filter media 9 in a manner to
get entrapped in an existing faceplate. In one embodiment of the
present invention at least one fiber 51 absorbs water. In one
embodiment of the present invention the at least one fiber 51
absorbs water and expands helping hair entrapment prevention. There
is no limitation to how filter media 9 functions to inhibit or
prevent hair entrapment. Filter media 9 is capable to be configured
other ways to inhibit or prevent hair entrapment and all ways are
envisioned by the present invention and fall into the scope of the
present invention. In one embodiment of the present invention at
least one fiber 51 allows water to pass right through the fiber.
This helps to decrease water restriction out a water return
fitting. In one embodiment of the present invention fibers 51 are
configured or any other fiber disclosed herein is configured or/and
made of a material that allows at least a portion of ISO12103-1A4
coarse test dirt to pass through the fiber. In one embodiment of
the present invention at least one and more preferably all fibers
51 are configured to absorb water. In one embodiment of the present
invention fibers 51 are configured to absorb water at least two
fibers 51 and more preferably all fibers 51 expand or is
stretchable over 1.5 their size before water pump activation and
high velocity water flow. In one embodiment of the present
invention filter 9 is configured to stretch about 2.5 times its
original pre-water draw through size. In one embodiment of the
present invention filter media 9 is configured to achieve its goals
with less than 150 gallons water flow per minute. In one embodiment
of the present invention filter media 9 is configured to achieve
its goal with less than 100 gallons water flow per minute. In one
embodiment of the present invention filter media 9 is configured to
achieve its goal with more than 100 gallons water flow per minute.
In one embodiment of the present invention filter media 9 is
configured have at least some fiberglass or another material to
extend its useful life beyond 50 bath cycles, and more preferably
beyond 100 bath cycles. The present invention envisions all
materials to achieve this goal and all materials fall into the
scope of the present invention. In one embodiment of the present
invention, fibers 51 are configured having small spurs 53 to
inhibit or prevent hair 10 from going through filter media 9 in a
manner to prevent or inhibit hair entrapment in existing faceplate
14. The spurs are only shown by way of example and not limitation.
The spurs are only an example of one means functions to configure
water flow through passages to inhibit or prevent hair from going
through them in manner that they do not get entrapped in the filter
or the cover or an existing faceplate. The present invention
envisions all means functioning to configure the water flow through
passages on a cover, filter or faceplate to inhibit or prevent hair
entrapment and all means functioning fall into the scope of the
present invention. In one embodiment of the present invention
filter media 9 has at least a segment is made of polyvinylidene or
some other material that resists creasing. The present invention
envisions all materials that resist creasing and all materials fall
into the scope of the present invention. In one embodiment of the
present invention utilizing a crease resistant or crease
inhibiting, the material aids in reducing hair entrapment and/or
increasing the useful life. In one embodiment of the present
invention filter media 9 is made of a syrupy extruded polymer. In
one embodiment of the present invention fibers 51 are made not to
substantially stretch or not stretch yet are knitted or weaved to
allow at least one water flow through passage to increase in
diameter the high velocity water flow passes through filter 9. In
one embodiment of the present invention filter media 9 is sonic
welded to a cover 2 or another cover. In one embodiment of the
present invention the knit or weave pattern is made of metal or
stainless steel, or metal or steel or a material having at least
eight percent chromium, or some other long lasting material. In one
embodiment of the present invention a segment of the invention is
made of at least eight percent chromium. This is important because
of the normal water chemistry environment one embodiment of the
current invention functions in. In one embodiment of the present
invention filter media 9 comprises a foam material.
[0060] Referring next to FIG. 10 shows an illustration of how one
embodiment of filter media 9 is configured to operate. Filter media
9 is shown with water flow through passage 55. As high velocity
water flow is drawn through water flow through passage 55, water
flow through passage are configured to allow ISO12103-1 A 4 coarse
test dirt to flow through, but in this embodiment, the diameter of
water flow through passage 55 does not expand larger than the
diameter D of hair 10. This provides that hair 10 does not pass
through filter media 9 in a manner that it gets entrapped in an
existing faceplate yet provides not to significantly reduce water
flow out a return fitting as disclosed above. In one embodiment of
the present invention hair 10 is about 50 microns in diameter. In
one embodiment of the present invention hair 10 is about 75 microns
in diameter. In one embodiment of the present invention hair 10 has
yet another diameter. In one embodiment of the present invention
filter media 9 has at least a segment having a denier thickness
between 3 and 120, or 10 and 80, or 25 and 80 or over 120. In one
embodiment of the present invention filter media 9 is configured to
disrupt or alter water vortex behind an existing faceplate. In one
embodiment of the present invention filter media 9 provides to aid
in a differentiation of pressure between the front of filter media
9 and the backside of existing faceplate 14. In one embodiment of
the present invention this differentiation of pressure aids in
habiting hair 10 from going through an existing faceplate in a
manner it gets entrapped in an existing faceplate. In one
embodiment of the present invention faceplate 14 is secured to
housing 15 requiring a tool for removal. In one embodiment of the
present invention, as noted above, filter media 9 is integrated
with faceplate 14. In one embodiment of the present invention
faceplate 14 is made through a plastic injection process and filter
media 9 that is integrated with faceplate 14 is not made through
the injected molding process. In plainer words, faceplate 14
becomes the first faceplate for a suction fitting that has an
integral expandable filter segment. In one embodiment of the
present invention the filter media as described above is movable
and replaceable. With integrated filter media 9, faceplate 14 is
configured to housing 15 in a manner that when the center portion C
is subjected with a load point of 250 pounds faceplate 14 deflects
less than 3/4 inch in direction P. In one embodiment of the present
invention at least 20%, or 25%, or 40%, or 45%, or 50%, or 70%, or
all of the water flow through passages of filter media 9 is sized
smaller than 140 microns, or smaller than 100 microns, or smaller
than 75 microns, or smaller than 70 microns or smaller than 55
microns in diameter. In one embodiment of the present invention
filter media 9 water flow through passages are configured when high
velocity water passes through them at least 3% of the water flow
passages have a diameter larger than the total number of water flow
through passages. In one embodiment of the present invention filter
media 9 is made out of metal. In one embodiment of the present
invention filter media 9 is made out of metal that resists
corrosion for chemicals normally used in bathing water such as but
not limited to chlorine.
[0061] FIG. 11 shows one embodiment of the present invention cover
4A having one embodiment filter media 9 integrated with cover 4.
Cover 4A is configured to go over a suction housing 15 in FIG. 9 or
some other suction fitting know in the art such as the Mattson
suction fittings incorporated herein by reference. Opening 13
accepts an attachment means 14A to secure cover 4A to an existing
suction housing. The cover 4A, housing 15 in FIG. 9, attachment
means 14A and opening 13 are shown by way of example and not
limitation. The present invention envisions all configurations and
attachment means all configurations and attachment means fall into
the scope of the present invention. The attachment means in one
embodiment of the present invention is to provide the faceplate
cannot be removed from a suction housing without the aid of a tool.
The term tool herein means any device other than a person's body
part. In one embodiment of the present invention Cover 4A also
known as a faceplate is configured to meet the voluntary ASME
standard. In other words, cover 4A will not deflect more than 3/4''
when attached to a suction housing configured for cover 4 and
preferably will not deflect more than 1/2'' when a load point of
150 or 250 pounds is subjected to center C. Yet, filter media 9 is
configured to flex and offer hair entrapment prevention. One way to
configure cover 4A to meet this strength tests and to resist
cracking is to make it out of a heavy gauge material. Heavy gauge
material is described by way of example and not limitation as the
present invention envisions all ways to reinforce cover 4A and all
ways fall into the scope of the present invention. Further, in one
embodiment of the present invention cover 4A is configured to
resist cracking when about 15 foot pounds impacts center C. Filter
media 9 has different embodiments that are described above in this
disclosure. In other words, filter media 9 is configured many ways
as described above to prevent hair entrappement instead of reducing
the chance of hair entrapment as other faceplates do. Therefore, in
one embodiment of the present invention filter media 9 and cover 4A
intergraded together in the manufacturing process as a single
part.
[0062] FIG. 12 one embodiment of cover 2 having tits 100. Water
flows in direction WF through water flow through passages 40. Cover
2 is shown by way of example and not limitation to describe the
function of this embodiment of the present invention. Generally a
hair 10 under high velocity water pressure lays up against a water
flow through passage 40. In other words, it is thought that it is
about mathematically impossible for a hair on a persons head to
enter a very small water flow through passage under high velocity
water flow from hair end A. When there is a pressure
differentiation hair 10 generally bends and moves through water
flow through passage 40. In this embodiment of the present
invention cover 2 has a tacky surface 500 between the water flow
through openings or a numerous number of tits 501. Each of these
means separately inhibit or prevent hair 10 that is attached to a
person's head (not shown) from bending in two and going through
cover 2 in a manner that it gets entrapped in cover 2 or existing
faceplate 14 (not shown). These means are shown by way of example
and not limitation as the present invention envisions all means to
prevent hairs on a persons head from bending in two and going
through cover 2 or faceplate 14 in a manner that a person drowns.
All ways fall into the scope of the present invention. In one
embodiment of the present invention filter media 9 is also
configured to inhibit hair on a persons head from bending in two
and going through filter media 9 in a manner that it gets entrapped
in cover 2 or existing faceplate 14 in a manner that causes
drowning. This is inherent to one embodiment of filter 9 that is
disclosed above. However, in one embodiment of the present
invention filter media 9 is made of a material having a tacky
surface or some other treated surface to accomplish the goal of
preventing hair on a personal head from going through the filter in
a manner that it gets entrapped causing drowning. In one embodiment
of the present invention the water flow through passages 40 of
cover 2 are positioned about two inches or about 2.5 inches or
about 3 inches or about 3.5 inches, or about 4 inches or about 4.5
inches or about 5 inches or about 5.5 inches, or about 6 inches, or
about 6.5 inches or about 7 inches or about 7.5 inches or more from
the water flow trough passages faceplate 14 or an existing
faceplate. Such as distant or distances prevents a hair of like
length from going through the existing faceplate and becoming
entrapped in the existing faceplate. In other words, if the water
flow through passages in cover 2 is positioned 3 inches from the
water flow through passages of an existing faceplate, hair 3 inches
long would not be able to go through the water flow through
passages an existing faceplate and become entrapped.
[0063] Referring next to FIG. 13, 14 shows cover 2 having filter
media 9 in front section A and side section B. In one embodiment of
the present invention Cover 2 and filter media 9 are referred to as
"combination". The combination is shown by way of example and not
limitation as the present invention envisions all combinations and
all combinations fall into the scope of the present invention.
Cover 2 is configured to secure over suction housing 15 with an
attachment member 24 requiring a tool for removal. The term tool
herein means a device separate from a body part. Cover 2 is
configured and suction housing 15 is configured to not flex more
than 3/4 of an inch in direction P when a load point pressure of
250 pounds is subjected to center C of cover 2. In one embodiment
of the present invention suction housing 15 is configured having
flange 23 for mounting suction housing 15 to a tub wall (not
shown). Flange 23 generally extends into a tub. Filter media 9 is
configured to inhibit or prevent hair from going through filter
media 9 in a manner that it gets entrapped in the water flow
through passages 9B. Cover 2 and suction housing 15 are shown by
way of example and not limitation. They both are capable to various
configurations to inhibit or prevent hair entrapment. All
configurations are envisioned by the present invention and fall
into the scope of the present invention. In one embodiment of the
present invention suction housing 15 has a threaded receiving
opening 29 to receive attachment member 24. Opening 29 is
configured to not cross thread allowing repeated putting on and
taking off over cover 2 or 3 in FIG. 3 or cover 2 in FIG. 14. In
one embodiment of the present invention opening 29 is a separate
metal insert. In one embodiment of the present invention filter
media 8 is made of the same material as a segment of cover 2. In
one embodiment of the present invention filter media 9 also known
in on embodiment of the present invention as a segment of cover 2
is made of plastic, or metal, or comprised in part of chromium, or
some other material. One embodiment of filter media 9 is configured
as one embodiment of cover 2 shown in FIG. 13. In one embodiment of
the present invention the space 60 between at least three water
flow through passages is less than 1400 microns and more preferably
less than 200 microns and most preferably less than 100 microns.
Flange 23 is a segment of the suction housing that is a segment of
a suction fitting. With these configurations, in one embodiment of
the present invention besides the hair entrapment benefits it also
solves the problem of water flow through the faceplate. Perry '339
appears to have less than 50% of the faceplate having water flow
through openings. If the opens are large, you would get more water
flow but could create a hair entrapment issue. In one embodiment of
the present invention over 50% of the cover or filter has water
flow through openings yet inhibits, restrains, or prevents hair
entrapment. Many spas because of the size pumps they use require 5
suction fittings or more. Cutting out two of these suction fittings
is a major cost benefit while still meeting the testing standards.
There is no known suction faceplate that meets the ASME published
testing standards and has over 50% of the total surface area as
water flow through passages except for the present invention. The
cover is configured to go over flange 23 to prevent hair from
wrapping around flange 23.
[0064] FIG. 15 shows one embodiment of a segment of filter media 9
having flow through passage 55. Water flow through passage 55 is
sized having a smaller diameter of hair 10 when hair 10 is bent in
two. In one embodiment of the present invention filter media 9 is
configured as with cover 2 (not shown) to meet the 250 pound load
and 14 pound impact tests when attached to a suction housing 15
(not shown) requiring a tool for removal.
[0065] FIG. 16 shows a segment of filter media 9 having water flow
through passages 40. Hair 101 attached to head 103 has a diameter
smaller that water flow through passages 40. However, because of
water pressure through the water flow through passages hair 101
lays across the water flow through passages in a manner that they
do not go through the filter media 9 in a manner or through an
existing faceplate water flow through passages that they get
entrapped in the water flow through passages of an existing
faceplate or a cover (not shown) that incorporates filter media 9.
In one embodiment of the present invention the hairs are held to
the filter media 9 due to water pressure force through filter media
9. In one embodiment of the present invention there is at least one
water flow through passage having a space of less than 150 microns
between the next water flow through passage. In one embodiment of
the present invention the water flow through passages are
configured to restrain, or inhibit, or prevent 15 hairs and more
preferably less than 15 hairs and more preferably less than 14
hairs and more preferably less than 13 hairs and more preferably
less than 12 hairs and more preferably less than 11 hairs and more
preferably less than 10 hairs and more preferably less than 9 hairs
and more preferably less than 8 hairs and more preferably less than
7 hairs and more preferably less than 6 and more preferably less
than 5 hairs and most preferably less than 4 hairs from going
through the water flow through passages in a manner they become
entrapped and a person cannot elevate their head above a
waterline.
[0066] FIG. 17 shows a side view of one embodiment of filter media
9 having water flow through passage 40. Even if hair 101 starts
through water flow through passage 40, water flow through passage
40 and other water flow through passages shown in FIG. 16 are
configured that as water pressure moves in direction WF hair 101 is
forced against front surface B of filter media 9 preventing or
inhibiting hair 101 to go through water flow through passage 40 in
a manner that it gets entangled with other hairs (not shown) and
causes hair entrapment.
[0067] FIG. 18 shows one embodiment of suction fitting 20. Suction
fitting 20 is shown by way of example and not limitation. Suction
fitting 20 is capable of other embodiments and all other
embodiments are envisioned by the present invention and fall into
the scope of the present invention. One embodiment of housing 24
has input water opening 25. Water moves through water opening 25
and generally the water outlet 19 of elbow fitting 31A. In one
embodiment of the present invention opening 26 is configured to
accept attachment means 28 that generally fits through attachment
opening 27 on cover 2. In one embodiment of the present invention
threaded nut 29B secures housing 24 to a tub wall (not shown). In
one embodiment of the present invention a tub wall is located
between threaded nut 29B and flange 27B. In one embodiment of the
present invention filter media 9 is incorporated into water flow
through passages 10. In one embodiment of the present invention
housing 24 is sloped from position A the most rearward portion of
housing 24 to position B the tub end of housing 24. The slope is
angled to compensate for tub wall draft not shown to allow water to
efficiently drain from housing 24 into a tub 6 in FIG. 1 or some
other tub. The outlet 19 of elbow fitting 31A is sloped upwards at
an angle to a water pump therefore, allowing water to efficiently
drain from the water pump through the elbow fitting, through the
housing and through cover 2 and into a tub. In other words in one
embodiment of the present invention suction fitting is configured
to a tub to provide a sloped downward angle from the water pump all
the way through the suction fitting. In one embodiment of the
present invention housing 24 or elbow fitting 31A have a cavitation
port 11 or 15. When a user blocks of the water flow through
openings water suction draw through cover 2 decreases preventing
body entrapment. The art has attempted to solve the problem of body
entrapment by providing cavitation systems as seen in U.S. Pat. No.
6,038,712 to Chalberg et al. Chalberg appears to teach that a
specified point on the faceplate (center) requires complete
blockage before cavitation occurs. It appears that if the center is
not blocked no cavitation occurs. Simply this is not a complete
solution. The present invention will cause cavitation if only the
side water flow through passages 10B or even a few of the front
water flow through passages are block. The way this works is water
passes the cavitation end of one of cavitation port 11 or 15. When
only some of the cover 2 water flow passages (any location on cover
2) are block, air moves into the cavitation port 11 or 15 and
decreases water suction draw through cover 2 as the air cavitates
the water pump. One skilled in the art would assume that a
cavitation opening less than 1/2 inch in diameter that is located
about parallel to the inside of a housing would cavitate the water
pump when water passes over it without any blockage of the cover or
faceplate and would noticeably reduce the water output of a water
return fitting. In other words over the prior art, the water draw
through the water flow through openings incrementally decreases in
relationship to the amount of water flow through passages that are
blocked. In one embodiment of the present invention cover 2 is
configured to suction housing 24 where it will not deflect more
than 3/4 of an inch when a load pressure point of 250 pounds is
subjected to center C. In one embodiment of the present invention
for safety reasons a tool is required to remove cover 2 from
housing 24. Cover 2 and suction housing 24 are configured to
accommodate water flows, configured to provide the same water
restriction out a water outlet fitting and configured to provide
hair entrapment safety as other embodiments of the present
invention disclosed herein. One embodiment of the present invention
is configured to meet the voluntary ASME/ANSI standard mentioned
above. 10BC is a blow up of one embodiment of a water flow through
passage 10B having filter media 9 and showing as an example and not
limitation water flow through passage 50. All three water flow
through passage 50 are square or rectangular and having a diameter
plus or minus 20 micron of the other two water flow through
passages. In one embodiment of the present invention each water
flow through passage is sized less than 1400 microns in diameter
and more preferably less than 200 microns in diameter most
preferably less than 100 microns in diameter. In one embodiment of
the present invention at least two and more preferably all the
water flow through passages are spaced less that 150 microns apart.
These configurations provide to distribute water suction draw
pressure through the water flow passages inhibit or preventing
water saturated hairs 110 on head 66 from bending in two and going
through the water flow through passages in a manner to cause hair
entrapment enough that a person cannot elevate their head above a
waterline (not shown). Head 66 is shown having 4 hairs 110 and in
is shown as an illustration and not limitation as head 66 also has
5, or 6, or 7, or 8, or 9, or 10, or 11, or 12, or more hairs (not
shown). In one embodiment of the present invention over 40% and
more preferably over 50% and most preferably of 70% of the surface
area 44 comprise water flow through passages. From reading this
disclosure is it common sense how this can be accomplished. In
other words, in one embodiment of the present invention cover 2 and
suction housing is configured to meet all strength and impact and
hair tests set out by plumbing standards and provides a higher flow
rate not previously attainable by the art. The whirlpool bathtub,
spa and swimming pool art suggests for suction fittings that
currently meet plumbing standards use only plastic parts made
through injection molding. It is not taught in the whirlpool bath
art how injection molding can produce water flow through passages
1400 microns or less in size that have a tolerance of plus or minus
20 microns for a faceplate and yet allow the suction fitting to
meet the tests. Using non injected plastic for the water flow
though passages does accomplish this goal. As an example and not
limitation when the cover 2 has over 50% of the surface area having
water flow through passages hairs per current plumbing standards
(at least 50) are lowered to about position C. The water pump (not
shown) is activated and water is drawn through cover 2 and it takes
less than 5 pounds force to remove the hairs and provides more
water draw through the cover for the same amount of force to remove
the hair from the cover. Besides adding safety, this embodiment
increases water flow not previously attainable in the art. The term
efficient water flow herein means more water draw than a faceplate
having less than 50% of the total surface area covered with water
flow through passages yet meets a five pound hair pull test. Filter
media 9 is made out of a material that will not corrode in water
having a concentration of 1/4 of 1 part per million and less than
10 parts per million of chlorine. One embodiment utilizes some
chromium to accomplish this goal however other materials are
envisioned by the present invention and fall into the scope of the
present invention. This embodiment of the present invention as with
certain other embodiments of the present invention restrains hair
entrapment while not significantly decreasing water flow out a
water return fitting. Embodiments of the present invention also
work in other ways to restrain hair from going through the
invention in manner that the hairs cause entrapment and thus
drowning. This written disclosure may be silent to all these ways
and to all the means functioning to provide suction fitting safety
it is understood that the present invention envisions all these
ways and thus all inherent to the present invention. Filter media
segment 9 in one embodiment of the present invention is configured
to cover 2 the filter media segment does not deflect more than 3/4
of any inch in any direction when a load pressure point of one
pound is applied to center A. This is one way that helps to
restrain hair from going through the filter media segment in a
manner to cause hair entrapment. Most known suction fittings used
on whirlpool bathtubs, spas and swimming pools in the United States
have faceplates having fewer than 1,000 water flow through openings
and more generally less than 500. As an example, U.S. Pat. No.
5,799,339 to Perry appears to have less than 60% water flow through
passages as evident by the spacing between the water flow through
passages. One embodiment of the present invention has over 50% of
the total surface area having water flow through passages and more
preferably more than 60% and most preferably more than 70 percent.
In one embodiment of the present invention a second filter media
segment is located within one inch of filter media segment 9. If or
when hairs goes through the second filter media segment filter
media segment 9 or another filter media in close behind and in
proximity of the second filter segment prevents the hairs from
twisting together or in some other manner causing hair entrapment.
One of ordinary skill in the art from this disclosure would know
how to accomplish this goal. In one embodiment of the present
invention cover 2 is configured to have a depth of less than 1 inch
from position D to position E and more preferably a depth of less
than 1/2 inch from position D to position E and more preferably a
depth of less than 1/4 inch from position D to position E and most
preferably less than 1/8 inch. Because of hair entrapment issues
faceplates for whirlpool bathtubs and spas that meet the 5 pound
hair pull test have not be able to meet small width dimensions. One
embodiment of the present invention solves this problem and thus
allows more bathing room inside a tub. In one embodiment of the
present invention cover 2 is configured to have only water flow
through passages in the front surface. Because of hair entrapment
issues faceplates for whirlpool bathtubs and spas that meet the 5
pound hair pull test a faceplate having water flow through passages
in only the front surface are currently not used for whirlpool
bathtubs or spas. In one embodiment of the present invention cover
2 has a length from position F to position G of less than 2 feet
and more preferably a less than 1 foot and more preferably a less
than 8 inches and more preferably a less than 6 inches and more
preferably a less than 4 inches and most preferably a less than 3
inches. Because of hair entrapment issues faceplates for whirlpool
bathtubs and spas that meet the 5 pound hair pull test a faceplate
less than 3 inches in length is not known for spas, or swimming
pools. In one embodiment of the present invention the height of
cover 2 is preferably a less than 1 foot and more preferably a less
than 8 inches and more preferably a less than 6 inches and more
preferably a less than 4 inches and most preferably a less than 3
inches. In one embodiment of the present invention filter media 9
has the same dimensions as disclosure for cover 2. In one
embodiment of the present invention suction housing 24 has a radius
R of over 1/4 inch and more preferably over 1/2 inch and most
preferably over 1 inch in the input orifice 25 at about front
position N to position M. It has been found that a large radius at
this point increases water flow through the suction fitting thus
providing for efficient water flow. Increased water flow for a
given sized suction fitting is the goal of the art and is now
achievable due to the safety aspects of the present invention. In
one embodiment of the present invention there is at least one water
flow through passage having a space of less than 150 microns
between the next water flow through passage. In one embodiment of
the present invention the water flow through passages of cover 2
are configured to restrain, or inhibit, or prevent 15 hairs and
more preferably less than 15 hairs and more preferably less than 14
hairs and more preferably less than 13 hairs and more preferably
less than 12 hairs and more preferably less than 11 hairs and more
preferably less than 10 hairs and more preferably less than 9 hairs
and more preferably less than 8 hairs and more preferably less than
7 hairs and more preferably less than 6 and more preferably less
than 5 hairs and most preferably less than 4 hairs from going
through the water flow through passages in a manner they become
entrapped and a person cannot elevate their head above a waterline.
In one embodiment of the present invention cover 2 has a segment
having over 101 water flow through passages per square inch and
more preferably more than 201 and more preferably more than 301 and
more preferably more than 401 and more preferably more than 501 and
more preferably more than 601 and preferably more than 701 and
preferably more than 801, and most preferably more than 899 water
flow through passages per square inch in at least a segment of
cover 2. There is no known art for a whirlpool bathtub or spa
suction fitting faceplate having over 201 water flow through
passages in a segment of the faceplate except for the present
invention. In one embodiment of the present invention cover 2 has
water flow through openings configured that when cover 2 is over an
existing faceplate 14 (not shown) cover 2 is removable with less
than 15 or 5 pounds pressure. As envisioned in FIG. 2 one way this
can be accomplished is through the sizing of the water flow through
passages. This is one example and not a limitation as the present
invention envisions all ways to configure cover 2 to be removed
from an existing faceplate with less than 15 pounds in one
embodiment and less than 5 pounds in another embodiment and all
ways fall into the scope of the present invention. In one
embodiment of the present invention the cover is configured for
direct abutment to an existing faceplate and for placement in about
a parallel manner to the existing faceplate so as to have about the
same water direction from a front of the water flow through passage
to the back of the existing faceplate. In one embodiment of the
present invention cover 2 has water flow through passages in a
front surface J and peripheral edge surface K, the cover 2
configured for direct abutment to an existing faceplate 14 (not
shown) of a suction fitting 15 (not shown) and for placement in
about a parallel manner to the existing faceplate 14 so as to have
about the same water direction from a front of the water flow
through passage to the back of a water flow through passage in the
front surface and rear surface of the existing faceplate, the cover
2 is configured to about the size of the existing faceplate 14, the
cover 2 is capable of accommodating a high velocity water flow of
at least thirty five gallons per minute, the cover 2 is configured
to not restrict water flow out a water return fitting
75 (not shown) by more than twenty five percent when the high
velocity water flow having one ounce of a specified test dirt is
passing through cover 2 over a twenty minute time period, the cover
2 is configured to the existing faceplate 14 to provide hair
entanglement safety, the cover 2 is configured so a person removes
cover 2 from over the existing faceplate with less than 15 pounds
of pressure. Cover 2 means functioning to keep at least a segment
of the cover in direct abutment with the existing faceplate 14, and
means functioning to keep at least a segment of the cover 2 mounted
in a parallel manner to the existing faceplate 14 until the person
removes the cover 2 from the existing faceplate 14. Hence if or
when hair becomes entangled around cover 2, cover 2 is removable
from existing faceplate 14 so a user cannot get their hair
entangled around faceplate 14. It is known in the art that existing
faceplates require a tool for removal. Thus cover 2 provides hair
entanglement safety not known in the art for an existing faceplate.
In one embodiment of the present invention the water flow through
passages of filter media 9 or cover 2 have a combined diameter or
area that is larger than the diameter or total area of input
orifice 25. In other words if the diameter of input orifice 25 is
three inches, all the water flow through passages of either cover 2
or filter media 9 are over three inches. This provides added safety
and efficient water flow through the entire suction fitting. In one
embodiment of the present invention cover 2 is configured to about
the shape of an existing faceplate and for placement over the front
surface of the existing faceplate. Thus cover 2 provides a real
world solution to the long need of preventing hair entanglement in
the peripheral edge and front surface of an existing faceplate
while not significantly restricting water flow out a water return
outlet fitting. In one embodiment of the present invention cover 2
has at least one segment of at least 200, or at least 300, or at
least 400 or at least 500 or at least 600 or at least 700 or at
least 800 or at least 900 or more water flow through passages per
square inch. From reading this disclosure one skilled in the art
would know how to accomplish this goal. In one embodiment of the
present invention a segment of cover 2 is configured for direct
abutment to an existing faceplate. From reading this disclosure one
skilled in the art would know how to accomplish this goal. The term
hair entanglement means to the degree a person cannot elevate their
head above a waterline. In one embodiment of the present invention,
for safety hair entanglement reasons, the cover is configured to be
removed by hand without a tool. In one embodiment of the present
invention cover 2 is configured to extend less than one inch pass
the front portion of an existing faceplate and more preferably less
than 1/4'' into a tub. From reading this disclosure one skilled in
the art would know how to accomplish this goal. In one embodiment
of the present invention at least a segment of cover 2 is made out
of injectable plastic. In one embodiment of the present invention
the abutment of filter media 9 as shown in FIG. 3 to the existing
faceplate inhibits water saturated hairs on a person's head from
getting entrapped around a portion of the filter media 9 extending
into a tub when the high velocity water flow is passing through the
filter media. In other words filter media 9 is configured to not
extend substantially into a tub (not shown). In one embodiment
filter media 9 is shown attached to water flow through opening 10
and in one embodiment between the faceplate and housing. In one
embodiment of the present invention a filter media segment 9 is
configured for placement in a parallel manner suction housing 24 so
as to have about the same water direction from a front of the water
flow through passage in filter media segment 9 to the back Z of
suction housing 24. In other words in one embodiment of the present
invention water flows in about a straight direction through at
least one water flow through passage to the back of housing 24
providing for high water flow through the cover while meeting the
five pound hair pull test disclosed herein. In one embodiment of
the present invention housing 24 has cross support 88 to support
cover 2. Cross support 88 acts like ribbing so cover 2 will not
deflect more than 3/4 of an inch when a load pressure point of 150
pounds is subjected to the front center portion C of cover 2. Cross
support 88 is shown by way of example and not limitation. Cross
support 88 is envisioned by the present invention capable of having
numerous configurations. All means functioning to prevent or
inhibit cover 2 from deflecting more than 3/4 of an inch is
envisioned by the present invention and falls into the scope of the
present invention.
[0068] FIG. 19 shows a rear view of one embodiment of cover 2
having filter media four filter media 9 segments having water flow
through passages 50 and ribbing 9E. Ribbing 9E provides that when
cover 2 is over suction housing 24 in FIG. 18 or suction housing 15
in FIG. 14, cover 2 will not deflect more than 3/4 of an inch when
a load pressure point is subjected to center C. The ribbing is
shown by way of example and not limitation as the present invention
envisions all means functioning to prevent cover 2 from deflecting
more than 3/4 of an inch when attached to a suction housing and all
means functioning fall into the scope of the present invention. In
one embodiment of the present invention cover 2 measures less than
6 inches in height, less than 6 inches in length and less than 31/2
inches deep. Cover 2 is configured as disclosed above to resist, or
prevent, or inhibit or restrain hair entrapment in cover 2 or an
existing faceplate. In one embodiment of the present invention
cover 2 has four radius corners 7. The water flow through passages
is shown as an illustration and not a limitation. In one embodiment
of the present invention one or more or all filter media segments 9
are removable from cover 2 and are replaceable. Filter media
segments 9 are shown by way of example and not limitation. The
present invention envisions any number of filter media 9 segments
in all configurations and all configuration fall into the scope of
the present invention. The water flow though passages shown are
generally numerous and in various locations on cover 2. FIG. 19
primarily is to show the ribbing and that the filter segments are
replaceable. Cross support 88 in one embodiment of the present
invention helps to reduce water vortex behind cover 2 and is shown
by way of example and not limitation. The present invention
envisions all ways to decrease water vortex and all ways fall into
the scope of the present invention.
[0069] FIG. 20 shows one embodiment of packaging 400. One
embodiment of the present invention attaches to or is enclosed in
packaging 400. One skilled in the art would know how to accomplish
this goal. In one embodiment of the present invention packaging 400
has safety wording 401 that expresses to a consumer the need for
one embodiment of the present invention cover 2 (not shown) or
filter media 9 (not shown) or the combination. In one embodiment of
the present invention packaging 400 has operation wording 401 that
expresses to a consumer how one embodiment of the present invention
cover 2 or filter media 9 operates as described herein or
otherwise. In one embodiment of the present invention a user is
depicted having at least one hair 402 caught in a faceplate 14. In
one embodiment of the present invention depicts having at least one
hair 402 caught in a faceplate 14. In one embodiment of the present
invention a pump 3 is shown on package 400 having hair 405 caught
in a segment of the pump. In one embodiment of the present
invention a hole 3 is in packaging 400 for mounting on a display.
In one embodiment of the present invention wording 406 is a
liability disclaimer. In one embodiment of the present invention at
least one word is in the color yellow or red. In one embodiment of
the present invention packaging 400 has wording 407 that expresses
a suggestion or absolute time when cover 2 or filter media 9 or
combination thereof should be replaced. There is no known prior art
for a safety suction device that restrains, inhibits, or prevents
hair in an existing faceplate for a suction fitting on a spa,
whirlpool bathtub, or swimming pool, that has packaging that
teaches or fairly suggests this method of marketing except for the
present invention. Packaging 400 is shown by way of example and not
limitation and the present invention envisions all packaging and
all packaging fall into the scope of the present invention.
