I l SHOWER RECEPTOR 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 [have now discovered a novel receptor component which may be utilized as the floor sector of a freestanding shower stall. My novel receptor is entirely free ofmetal and includes notonly the feature of a built-in channel for receiving shower stall walls but a threshold which will always'overflow before the sides and stilereceiving 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 ofa prior art receptor. over which the instant receptor is an improvement in that no means for attaching the walls to the receptor are necessary.

FIG. 2 is a cross-sectional view taken along line 2-2 of FIG. 1;

F IG. 3 is a front view as seen from the plane indicated by line 33 of FIG. 1; 1

FIG. 4 is a bottom view of the receptor of FIG. 1;

FIG. 5 is a cross-sectional view of a stile-receiving member as taken along line 5-5 of FIG. 1;

DESCRIPTION OF THE INVENTION INCLUDING PREFERRED EMBODIMENTS 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 stilereceiving 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 1 1 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 l2 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 l8 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 stilereceiving members.

FIG. 5 depicts a cross-sectional view of the stilereceiving 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 l5 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.
