Description
BACKGROUND OF THE INVENTION
In recent years, the construction of shower stall units of the
free-standing variety has increased materially. The earliest of the
commercially available shower units of this type were constructed
of metal and necessitated intricate attaching means for the various
components of the units, i.e. walls, hand rails, headers, receptors
etc. In most instances, these attaching means were also metal and,
as a result, the complete shower units were susceptible to
corrosion, rust etc., at the attached surfaces or any areas where
protective coatings (enamel etc.) on the metal were damaged or
otherwise removed or disrupted.
More recently, shower stall units have been constructed from
various non-corrosive materials such as plastics, see U.S. Pat. No.
3,609,773. Even these plastic showers, however, rely basically on
metal fasteners such as clips, screws etc. to secure walls, sills,
headers, receptors etc. together and therefore, while relieving
some of the corrosion problems, are still beset with corrosion
problems of their own.
SUMMARY OF THE INVENTION
I have now discovered a novel receptor component which may be
utilized as the floor sector of a free-standing shower stall. My
novel receptor is entirely free of metal and includes not only the
feature of a built-in channel for receiving shower stall walls but
a threshold which will always overflow before the sides and
stile-receiving members which afford a tight seal for stiles which
form the sides of a shower entranceway.
U.S. Pat. No. 3,363,267 affords an example of a prior art receptor
over which the instant receptor is an improvement in that no means
for attaching the walls to the receptor are necessary.

DESCRIPTION OF THE INVENTION INCLUDING PREFERRED EMBODIMENTS
FIG. 1 illustrates my novel receptor unit and, in particular,
depicts the top thereof with specific reference to its interior
components. The receptor is an all plastic integrally molded unit
and generally can be prepared from any such material which is known
to be moldable and has such properties so as to provide rigid,
impact resistant molded products. A preferred construction material
which may be used is that generally known as "pre-mix compression
molding compound", gunk-molding compound", "bulk-molding compound"
etc. and which is composed of an unsaturated polyester resin,
various fillers such as clay, calcium carbonate, etc., fibers such
as fiberglass, nylon, asbestos, etc., pigments and a cross-linking
agent such as styrene. The composition is a putty-like material
which is formed into the molded receptor by adding catalyst thereto
and compression molding the resultant mixture in a molding press
with downwardly or upwardly acting matched metal dies.
Again referring to FIG. 1, the receptor comprises an integrally
molded shell adapted to constitute the floor of a shower stall. The
shell includes sides 1, 2, and 3 with the remaining side comprising
the entranceway portion of the receptor and having upwardly open
stile-receiving members 4 and 5 at each end thereof. The
stile-receiving members are comprised of outer walls 6 and 7 and
inner walls 24 and 25 which preferably taper slightly (shown as an
angle in FIG. 5) terminating at bottom interiors 8 and 9,
respectively. A plurality of knob-like members 10 are positioned
equidistant from the innermost tapered portions of said inner and
outer walls at said bottom interiors of the stile-receiving
members. The stile-receiving members are adapted to receive the
stile portion (not shown) of the entranceway of the ultimate shower
unit. The stiles are maintained in locked contact with the
stile-receiving members by the combination of being of slightly
larger width than the space between the walls 6, 7, 24 and 25 and
the members 10 at the bottom interiors 8 and 9 and the tapered
sides.
A substantially upright section forms a wall 11 around the three
edges of the bottom floor 12 at sides 1, 2 and 3, of the receptor
while a second sections forms wall 17 on the fourth edge of the
bottom floor. Wall 11 extends upwardly above wall 17 as best seen
in FIG. 2. A drain opening 13 is positioned in the floor 12 at the
lowest point thereof, said floor being sloped in the direction of
said drain. An upwardly turned lip 14 is connected to the outer
portion of the three sides of the splash wall 11 and extends about
a major peripheral portion thereof thereby forming a trough 15
between said splash wall and said lip, the lip preferably being
higher than wall 11. Trough 15 preferably has tapered sides as
shown in FIG. 2 by an angle in order to tightly receive the wall
surround (not shown) of the shower stall. A downwardly extending
leg 16 (see FIG. 2) is connected to the bottom portion of said
trough in the area of said lip. The leg also extends about a major
peripheral portion of the splash wall in conformance to sides 1, 2
and 3. The leg terminates at a point beyond the lowest level of the
floor 12 and aids in supporting the receptor while also comprising
an apron or skirt around the receptor which conceals the
underpinnings thereof and also prevents foreign objects from
becoming jammed under the receptor floor.
Wall 17, which begins the formation of the threshold of the
entranceway of the ultimate shower stall terminates in a laterally
turned flange 18 extending outwardly therefrom. Flange 18 comprises
the threshold upper of the shower stall. The outer marginal edge of
said flange 18 terminates in a connecting flange 19 which also
extends downwardly beyond the lowest level of the floor 12 as does
leg 16, preferably to the same point as leg 16.
The walls 6, 7, 24 and 25 of stile-receiving members 4 and 5 blend
in to form a contoured surface wherever they meet flanges 18 and
19, lip 14 and leg 16 as best seen in FIGS. 3 and 4.
As seen in FIG. 2, a cross-sectional view along line 2--2 of FIG.
1, lip 14 preferably extends above the level of splash wall 11 and
flange 18 is preferably sloped inwardly toward the drain opening 13
of the floor 12. As a result, all water which reaches the threshold
flows back into the shower unit and out the drain rather than onto
the floor around the exterior of the shower stall.
A further feature fully depicted by FIG. 1 is the bullet-shaped
configuration of the stile-receiving members 4 and 5. This
configuration, although not critical, is preferred in that it lends
to the strength and rigidity of the ultimate shower stall.
Cut-outs 20 of FIG. 1 provide a widened sector for receipt of the
portion of the stile of the shower stall which engages and securely
connects the shower wall surround (not shown) which fits snuggly
into the trough 15. As can be seen clearly in FIG. 2, the floors 8
and 9 of the stile-receiving members are slightly lower than the
floor of the trough. This deeper recess enables a more secure
attaching of the stiles in the stile-receiving members.
FIG. 5 depicts a cross-sectional view of the stile-receiving member
taken along line 5--5 of FIG. 1. The outer wall 6 is clearly shown
as are knob-like members 10. The tapered sides of the
stile-receiving members are shown as an angle, as mentioned above.
The difference in height of the floor of the trough 15 and the
floor of the stile-receiving member 8 is clearly shown, as is
cut-out 20.
The bottom of my novel receptor is shown in FIG. 4. The blending of
the stile-receiving member sides 6 and 7 and lip 14 into a
contoured surface is best shown here. As can be seen, leg 16
extends around three sides of the receptor and also blends into the
sides of the stile-receiving members. A series of supporting ribs
21 extend below the floor 12 of the receptor and are integral
therewith in spaced relationship with one another. The ribs radiate
outwardly from circular member 22, which circumscribes the
periphery of drain 13 and is of the same depth as said ribs, in a
spoke-like configuration. Each of said ribs have positioned thereon
a set of feet 23 the height of which extend beyond the height of
the ribs. The height of each successive foot in each set proceeding
outwardly from the drain increases diametrically proportionally to
the slope of the floor 12, as best seen in FIG. 2. FIG. 6, a view
taken along line 6--6 of FIG. 4, best depicts the relative size of
said feet in comparison to the ribs.
The receptor of the instant invention is illustrated as being of
substantially square configuration, however, rectangular etc.
shapes could also be employed.
A series of stacking bosses, not shown, can be added about the
receptor along the outer edge of leg 16 in order to allow stacking
of a series of receptors inside one another in a nesting
arrangement for shipping and storage.
The interior side of the floor 12 may be formed such that a
non-skid surface, tiles etc. may be added thereto or molded
therewith during the production of the receptor.
Although my invention has been described above with some degree of
particularity and generally in its preferred forms, it is to be
understood that said preferred forms have been presented by way of
illustration only and that many modifications of both the
construction and arrangement of parts thereof may be made without
departing from the scope of the instant invention.
