Patent number: 5444953Abstract: An interior corner joint for joining wall board panels, particularly wall board panels simulating tiles embedded in grout, in a corner. The interior corner joint comprises a first base section; a second base section extending upwardly from said first base section and being perpendicular to said first base section; a rib extending upwardly from said first base section disposed adjacent to said second base section and canted toward said second base section, said rib, second base section, and first base section defining a channel adapted to receive a first wall board panel; and a flange at the distal end of said rib extending outwardly from said rib and inclined toward said first base section, said rib, flange and first base section defining a second channel adapted to receive a second wall board panel in substantially perpendicular relationship to said first wall board panel. With the two wall board panels inserted into the two channels the only exposed part of the joint is the flange.Type: GrantFiled: August 9, 1991Date of Patent: August 29, 1995Assignee: Trayco, Inc.Inventors: Paul J.

Patent number: 5263294Abstract: An extension joint for use with wall boards simulating tiles embedded in grout. The extension joint is disposed between two adjoining wall board panels and simulates a grout line. The wall joint comprises a long narrow strip of material having two spaced apart base sections and a raised ridge section connecting the two base sections. The top outer surface of the ridge section is concave to simulate a grout line.Type: GrantFiled: August 9, 1991Date of Patent: November 23, 1993Assignee: Trayco, Inc.Inventors: Paul J. Koenig, Douglas F. Hutchings, David W. Gibbard, Richard C. Manwell

Patent number: 5052160Abstract: A tile board made from a one piece sheet having top and bottom portions of contrasting colors. Grooves are machined through the top layer to expose strips of the bottom layer. The exposed strip divides the top layer into tile sized members which simulate inlaid tiles having beveled edges. The exposed strips of the bottom layers simulate recessed grout lines. Machining of the grooves through the top layer simultaneously forms the simulated tiles and simulated grout lines in the plastic sheet. The tile board can have a bent edge section to provide a finished tile look spanning a corner of two adjacent walls.This is a Continuation-in-Part of application Ser. No. 906,326 filed Sept. 11, 1986, now abandoned, which is a Continuation-in-Part of application Ser. No. 575,217 filed Jan. 30, 1984 (now abandoned).Type: GrantFiled: November 20, 1987Date of Patent: October 1, 1991Assignee: Trayco, Inc.Inventors: Barton K. Gentsch, Thomas M. Whitney

Patent number: 4691392Abstract: A joint for a plastic bathtub includes a tub support member that has two channels. The first receives a flange of the bathtub. The support member has its second channel receiving fasteners which affix the support member to a wall. A trim molding is then snap fitted over the second channel to conceal the fasteners and to provide for an aesthetically appealing joint appearance. End caps have fingers which are received in the second channel and are caulked in place to conceal the open end of the joint.Type: GrantFiled: February 10, 1986Date of Patent: September 8, 1987Assignee: Trayco, Inc.Inventor: Thomas H. Whitney

Patent number: 4598433Abstract: A shower stall assembly includes a one-piece molded PVC door that has an outwardly curved main section, integral handles and an outer perimeter which overlaps the perimeter frame about the opening of a shower stall. The shower stall has a header section which connects two sliders, each on a transverse rail member. One rail member spans the shower stall opening and the other rail member extends rearwardly to the rear shower stall wall. The shower stall door can be pivoted inwardly from its closed position to an open position in the shower stall.Type: GrantFiled: May 18, 1984Date of Patent: July 8, 1986Assignee: Trayco, Inc.Inventor: Thomas H. Whitney

Patent number: 4551869Abstract: A floor support for a plastic bathtub has a top panel and integral ribs injected molded from PVC plastic. The panel has an upper contoured surface which matches the contour of the underside surface of the plastic bathtub. The depending support ribs provide for structural support and for seating legs which elevate the support above floor level. The top panel has a drain support section with an aperture therethrough to align with the aperture through the floor of the bathtub and provides a seat for the drain pipe. The floor support is solvent welded to the underside of the plastic bathtub to provide for a durable, rigid and lightweight tub.Type: GrantFiled: March 20, 1984Date of Patent: November 12, 1985Assignee: Trayco Inc.Inventor: Thomas H. Whitney

Patent number: 4316295Abstract: A knocked-down kit for assembling a shower stall or bath tub enclosure comprises a base panel, dome panel and three side panels, the side panels being interlocked by a split clamping tube which resiliently clamps together outwardly extending flanges along the abutting vertical edges of the side panels, and the side panels being interlocked with the base panel by a resilient flange which snaps over an outwardly extending flange along the upper periphery of the base panel as the side panels are lowered onto the base panel. The interlock between the dome and side panels is symmetrically opposite to the base-side panel interlock.Type: GrantFiled: March 31, 1980Date of Patent: February 23, 1982Assignee: Trayco, Inc.Inventors: Thomas M. Whitney, Gerald Gower

Patent number: 4246227Abstract: Disclosed are an integral plastic bowl, waterway and trap for a toilet and the method of making the product. The bowl is concave and leads into a trap which may be interconnected with a standard closet flange. The waterway is vertically aligned with the trap and slopes downwardly from an inlet to an outlet, which is preferably at a position near the bottom interior of the bowl and which also preferably includes a wall surface in overlying alignment with at least a portion of the downwardly sloping waterway portion. During flushing, water from a reservoir flows down the waterway, against the outlet wall surface causing a vortex in the bowl, and then out of the bowl into the trap. In the method of making the product, a plastic parison is positioned between the sections of a blow mold. Next, the mold sections are closed, pinching portions of the parison shut to partially form the trap and waterway and enclosing another parison portion in a bulbous mold cavity.Type: GrantFiled: February 26, 1979Date of Patent: January 20, 1981Assignee: Trayco, Inc.Inventors: Samuel C. Crosby, Thomas M. Whitney, William F. Price

Patent number: 4176413Abstract: An integral, unitary plastic tank and rim flush for a toilet are disclosed, along with the apparatus and method of manufacture. The tank includes a bottom wall and sidewalls, one of which is integral with an essentially tubular water passageway. The rim includes an oval-shaped, hollow duct which is integral with the passageway and includes a plurality of spaced openings in a bottom wall surface to distribute water around the periphery of a toilet bowl. In the method of making the product, an elongated thermoplastic parison is positioned between a pair of blow mold sections. Next, the sections are closed, enclosing respective parison portions within a tank cavity, a passageway cavity and a rim cavity. Blow fluid under pressure is introduced into the parison portion within the tank cavity, resulting in the various cavity-enclosed parison portions being blown to their final shape. After cooling, the article is removed from the mold, trimmed and drilled to form the final product.Type: GrantFiled: June 12, 1978Date of Patent: December 4, 1979Assignee: Trayco, Inc.Inventors: Thomas M. Whitney, Samuel C. Crosby
