Description
CROSS-REFERENCES TO RELATED APPLICATIONS
[0001] This application claims the benefit of U.S. Provisional
Application No. 61/805,743, filed on Mar. 27, 2013 and U.S. patent
application Ser. No. 14/219,870, filed on Mar. 19, 2014, which are
both incorporated by reference in its entirety herein for all
purposes.
STATEMENT REGARDING FEDERALLY SPONSORED RESEARCH OR DEVELOPMENT
[0002] Not Applicable
INCORPORATION-BY-REFERENCE OF MATERIAL SUBMITTED ON A COMPACT
DISC
[0003] Not Applicable
BACKGROUND
[0004] Metal kitchen drain lines are subject to accelerated
deterioration and clogging because the drain lines are exposed to
acids, oils, fats, food materials, and mineral deposits. Larger
food materials can cause drain lines to become clogged, and mineral
deposits and other reactive materials can cause drain lines to
corrode. Although transitioning from metal pipes to plastic pipes
or ABS pipes has resolved many issues related to corroding and
collection of mineral deposits, like metal pipes, ABS pipes still
clog due to the passage of food and other particles that move
through drain lines.
[0005] FIG. 1 is a diagrammatic illustration of a prior art kitchen
sink, drain, and drainage line. Generally, kitchen sinks define a
hole 17 which accepts a sink drain attachment. The sink drain
attachment comprises a strainer 10, sometimes referred to as a
basket strainer or drain body, which has a flange 11 that extends
over the edge of the hole in the kitchen sink basin 2. The strainer
10 includes a much-reduced diameter threaded portion 12 for
connection to a strainer nut 14 or other attachment means to the
drainage piping 16. The strainer 10 may include a removable basket
or a garbage disposal adapter.
[0006] FIG. 2 is a diagrammatic illustration of a typical double
basin kitchen sink where the strainer 10 is attached to at least
one basin 2a and a drainage piping 16; the other basin 2b has a
garbage disposal 4 connected thereto. It will be appreciated that
the components and drainage connection systems illustrated in FIG.
1 and FIG. 2 are exemplary.
[0007] Typically, the kitchen sink hole 17 is 3.5 inches in
diameter. Referring to FIGS. 1, and 2, since the strainer 10
emerges into a much-reduced diameter threaded portion 12, the area
of the strainer orifice is much smaller than the area of the
strainer 10.
[0008] Because of the relatively small surface area available for
debris retention within the strainer 10 and the requirement for
threaded portion 12 to terminate at a 90-degree angle with the
strainer 10, it is difficult to remove certain types of debris from
the bottom of the strainer 10. Some existing strainers 10 may allow
larger debris to pass through to older, corroded, or clogged drain
lines. This larger debris may exacerbate damage to existing drain
lines or create damage.
[0009] To overcome these problems removable strainers have been
employed; such strainers or baskets are removably inserted into the
top of the drain body 10, and then removed and emptied as needed.
However, these removable strainers also present drawbacks.
[0010] Removable strainers do not provide a large strainer orifice.
Additionally, the user of the kitchen sink will need to remember to
insert the removable strainer before using the sink. Removable
strainers are often stored on the side of a sink becoming an
eyesore and can easily be misplaced. Moreover, many removable
strainers are made from low quality material, such as plastic or
rubber, or a very fine mesh material which may break down over
time.
BRIEF DESCRIPTION OF INVENTION

DETAILED DESCRIPTION OF THE INVENTION
[0022] Pursuant to the patent laws of the United States, this
detailed description discusses various illustrative embodiments of
a double-walled sink strainer 100. These illustrative embodiments
are provided, as required by law, in order to give persons having
ordinary skill in the art a full, clear, and concise description of
the invention defined by the claims, and to enable such a person to
appreciate and understand how to make and use, not only the
described illustrative embodiments of the present double-walled
strainer 100, but various other embodiments that fall within the
conceptual scope of present double-walled strainer 100, despite
those various other embodiments not being explicitly described
herein.
[0023] Neither this detailed description, nor the accompanying
drawings, act to define or otherwise limit the inventive subject
matter to which the inventors and/or the inventors' assignee(s)
claim exclusive rights; that is the exclusive role of the claims
which follow. Accordingly, this description should not be read to
limit the scope of the claimed subject matter, nor imply any
preference of the described embodiments over any other embodiment,
unless such a limitation or preference is explicitly identified
herein. For example, although the illustrative embodiments focus on
a double-walled strainer 100 which is used within a kitchen sink,
the inventive methods and systems defined by the claims are not so
limited.
[0024] Referring to FIGS. 3-7, the double-walled sink strainer
("Strainer") 100 is comprised of a strainer screen 101, a flange
clamp 102, and a strainer body 103 having a threaded portion 104
for connection to a strainer nut 14, or other attachment means, for
attachment to the drainage piping 16. Although the drawings herein
depict a generally hemispherical-shaped strainer body, the strainer
body 103 can be any shape.
[0025] According to embodiment, the strainer screen 101 is a
basket. According to an embodiment, the strainer screen is a basket
having a substantially vertical wall 101b. According to an
embodiment, the strainer screen 101 is a basket having a
substantially vertical wall 101b and a substantially horizontal
base 101c. According to an embodiment, the strainer screen 101 is a
basket that extends into and forms a strainer screen flange
101a.
[0026] According to an embodiment, the strainer screen 101 is a
mesh screen having apertures 110 extended throughout. According to
an embodiment, the strainer screen is made from a single sheet of
perforated stainless steel, which is stamped in a die to take on
the shape of a basket. According to an embodiment, the diameter of
the strainer screen 101, measured from strainer screen wall 101b to
strainer screen wall 101b, is in the range of 2.0-3.2 inches and
preferably in the range of 2.3-2.8 inches. According to an
exemplary embodiment the diameter of the strainer screen 101 is
2.52 inches.
[0027] According to an embodiment, the strainer body 103 is a
semi-spherical body. According to an embodiment, the strainer body
103 is a substantially cylindrical body having a tapered portion
103c connected to a threaded portion 104. According to an
embodiment, the strainer body 103 has a substantially vertical wall
103b. According to an embodiment, the strainer body 103 extends
into and forms a strainer body flange 103a. According to an
embodiment, the threaded portion 104 ends in a right-angled plate
120 which defines mechanisms 121 which allow tools to mate the
strainer 100 to a sink basin. Preferably, the threaded portion 104
is configured to mate with a strainer nut 14, or other attachment
means, for connection to drainage piping 16. According to an
embodiment, the diameter of the strainer body 103, measured from
strainer body wall 103b to strainer body wall 103b, is in the range
of 3.0-4.0 inches and preferably in the range of 3.0 to 3.5 inches.
According to an exemplary embodiment, the diameter of the strainer
body 103 is 3.28 inches.
[0028] According to an embodiment, the strainer screen flange 101a
is configured to operably connect the strainer body flange 103a as
shown in FIGS. 4, 6 and 7. According to an embodiment, the flange
clamp 102 operably mates the strainer screen flange 101a to the
strainer body flange 103a.
[0029] According to an embodiment, when the strainer screen flange
101a is operably connected to the strainer body flange 103a, the
strainer screen wall 101b is substantially parallel to the strainer
body wall 103b, thus forming a double-walled structure with a gap
115 there-in-between. According to an embodiment, the gap 115 is in
the range of 0.25-1.0 inch and preferably in the range of 0.65-0.85
inches. According to an exemplary embodiment, the gap 115 is 0.76
inches
[0030] This the double-wall configuration (101b and 103b) creates a
strainer 100 with a large straining area because a larger number of
apertures 110 come in contact with liquid. Generally, in other
configurations, apertures may be blocked by other portions of the
drainage assembly.
[0031] According to an embodiment, the flange clamp 102 is operably
attached to the strainer screen 101 and the strainer body 103.
According to an embodiment, the flange clamp 102 operably clamps
the strainer screen 101 to the strainer body 103. According to an
embodiment, the flange clamp 102 forms a "C" shaped cross section
which is comprised of a side 102c and a lip 102d. FIG. 5 shows a
detail view of the `C`-shaped cross section.
[0032] Referring now to FIGS. 8-9, according to an embodiment, the
strainer 100 may be partially enclosed in a housing 106 when being
installed in a working environment. According to an embodiment, the
strainer 100, in its final assembled position, may be placed on a
gasket 114 or other type of sealant which rests on a supporting
flange of the housing 106. A housing nut 108 may then mate with the
threaded portion 104 of the strainer 100 to secure the strainer to
the housing 106 and the sink environment. Further, the strainer 100
may connect to drainage piping 16 by means of the threaded portion
104 of the strainer 100 and a strainer nut 14, or other means.
