Cl. 4-145 7 Claims ABSTRACT OF THE DISCLOSURE A bathing fixture, such as a shower pan or tub, comprising an upper fluid retainer member having an inclined bottom wall with a drain opening therein, and a lower support member receiving the fluid retainer member and having a bottom wall which includes rib portions conforming to the incline of the bottom wall of the fluid retainer member and en-gagingly supporting the same.
SUMMARY OF THE INVENTION This invention relates to a bathing fixture and has particular application to a shower pan or similar article, such as a tub.
The bathing fixture of this invention comprises an upper fluid retainer member and a lower support member. The fluid retainer member includes a bottom wall and an upwardly extending circumferential side wall. The bottom wall has a drain opening therein and is inclined toward the drain opening. The support member includes a bottom wall and an upwardly extending circumferential side wall. The bottom wall of the support member is adapted to rest upon a substantially level surface and includes a plurality of inclined rib portions which conform to the incline of the bottom wall of the fluid retainer member. The fluid retainer member is seated Within the support member and has its bottom wall resting upon and supported by the conformed rib portions of the lower support member.
The bathing fixture of this invention is preferably formed from plastic sheet material and because of its two-piece construction provides a firmly supported, shaperetaining fixture of economical construction.
Accordingly, it is an object of this invention to provide a bathing fixture of two-piece construction in which a fluid retainer member having an inclined bottom wall is seated within a support member having portions extensively engaging and supporting the bottom wall of the retainer member.
It is another object of this invention to provide a bathroom fixture comprising an upper fluid retaining member and an engaging lower support member which are formed from plastic sheet material.
It is another object of this invention to provide a shower pan of high strength and economical construction.
Other objects of this invention will become apparent upon a reading of the inventions description.
BRIEF DESCRIPTION OF THE DRAWINGS FIG. 1 is a perspective view of a shower pan constructed in accordance with my invention.
FIG. 2 is a perspective view of the shower pan showing the component parts thereof in separated form.
FIG. 3 is a cross sectional view taken along line 3-3 of FIG. 1.
DESCRIPTION OF THE PREFERRED EMBODIMENT The preferred embodiment illustrated is not intended to be exhaustive or to limit my invention to the precise form disclosed. It is chosen and described in order to Patented Sept. 21, 1971 best explain the principles of my invention and its application and practical use to thereby enable others skilled in the art to best utilize the invention.
As an illustrative example of a bathing fixture of my invention, I have chosen a shower pan, hereinafter generally designated by the reference numeral 10. It is to be understood, of course, that my invention would have equal applicability to other similar bathing fixtures, such as bathtubs. Shower pan 10 includes a lower support member 12 and an upper fluid retainer member 13 which is seated within support member 12. Both support member 12 and fluid retainer member 13 are preferably formed from plastic sheet material which is heat formed, such as by vacuum forming, into desired shape. It has been found that satisfactory shower pan strength and rigidity can be obtained by utilizing acrylanitrile-butadiene-styrene sheet material having a thickness of .125 inch.
Upper fluid retainer member 13 includes a bottom wall 14 which has a drain opening 15 therein and which is inclined downwardly toward drain opening 15. Drain opening 15 may be centrally located in bottom wall 14 and is adapted to receive a drain fitting (not shown). Upper fluid retainer member 13 includes a circumferential side wall 16 which extends upwardly from bottom wall 14 thereof and which may have an off-set upper marginal portion 17 to provide an underlap and support for the siding of the shower stall in which pan 10 may be installed.
Lower support member 12 includes a bottom wall 18 which is adapted to rest upon a substantially level foundation and a circumferential side wall 20 which extends upwardly from bottom wall 18 thereof and which conforms in shape to side wall 16 of the upper fluid retainer member.
Bottom wall 18 of lower support member 12 has a plurality of upwardly projecting rib portions 19 formed therein. Each rib portion 19 preferably includes a flat upper surface 21 and is preferably spaced not more than a width apart from adjacent rib portions. Upper fluid retainer member 13 is so sized that it can be snugly seated within lower support member 12 as best shown in FIGS. 1 and 3 with bottom wall 14 resting upon and being supportingly engaged by upper surfaces 21 of lower support member rib portions 19. The upper surface 21 of each rib portion 19 conforms to the shape or incline of the engaging portion of bottom wall 14. Side wall 20 of the lower support member 12 should sufficiently overlap side wall 16 of upper fluid retainer member 13 so that member 13 will be restrained from lateral movement within member 12 and may extend, if desired, to the off-set side wall margin 17 of member 12.
Rib portions 19 serve not only to support the bottom wall 14 of upper fluid retainer member 13 but also to strengthen and rigidify lower support member 12. Upper fluid retainer member 13 is preferably formed with no rib portions therein and consequently is more flexible than member 12 so as to enable its bottom wall 14 to fully conform to the slope of rib portions 19 of the lower support member and thereby allow for any irregularity in the forming of members 12 and 13 and uneveness of the lower support member. Bottom wall 18 of lower support member 12 preferably has an aperture 22 therein which registers with drain opening 15 in the upper fluid retainer member 13 and which serves to receive a portion of the drain fitting (not shown).
Shower pan 10 can be formed into a variety of shapes other than the rectangular shape illustrated, such as square, hexagonal, or circular, and can be easily installed by simply stapling or nailing the lower support member 12 between rib portions 19 to the foundation and inserting the uper fluid retainer member 13 therein. If desired,
an adhesive can be applied between members 12 and 13 to ensure a permanent fit therebetween.
What I claim is:
1. A bathing fixture comprising an upper fluid retainer member and a lower support member, said upper fluid retainer member including a bottom wall and an upwardly extending circumferential side wall, said bottom wall having a drain opening therein and being inclined from said side wall downwardly toward said drain opening, said lower support member including a bottom wall and an upwardly extending circumferential side wall, the bottom wall of said lower support member being adapted to rest upon a substantially level foundation and including a plurality of upwardly extending rib portions, said rib portions having upper surfaces conforming to the incline of the bottom wall of said upper fluid retainer member, said upper fluid retainer member seating within said lower support member and having its bottom wall resting upon and supported by the conformed upper rib surfaces of the bottom wall of the lower support member.
2. The bathing fixture of claim 1 wherein the bottom wall of said upper fluid retainer member is flexible 3. The bathing fixture of claim 1 wherein each conformed rib surface is flat and supportingly engages a portion of the bottom wall of said upper fluid retainer memher.
