[0001] This application claims the benefit of U.S. Provisional Application No. 63 / 762,036, filed Feb. 23, 2025.BACKGROUND

[0002] A wall drain (sometimes called a wall-mounted linear drain or in-wall drain) is a drainage system built into the base of the shower wall rather than the center or edge of the floor. Instead of water flowing toward a round drain in the middle, the floor slopes gently toward a long, narrow opening at the wall.

[0003] This design hides the drain behind a removable cover or tile-in grate, creating a clean, minimalist look.BRIEF DESCRIPTION OF THE DRAWINGS

[0024] Embodiments of the present invention include a wall drain assembly and a method of installing the wall drain assembly. The wall drain assembly can be configured to be installed at an intersection of a wall of a shower stall and a floor of the shower stall providing an inlet along the intersection. More specifically, the wall drain assembly can be located substantially within the wall of the shower stall. Typically, only a thin slit along the wall / floor intersection can be visible in a finished shower enclosure. The wall drain assembly can include, but is not limited to, a drain body, a foam cover, coupling members, and a drain cover. The drain body can be made of any suitable materials including but not limited to stainless steel, reinforced and unreinforced plastics (including PVC), and aluminum. In some instances, an opening of the drain body located proximate the drain can be sloped such that water is directed towards the drain.

[0025] The wall drain assembly is designed for water to flow into an opening through a slit (elongated horizontal opening) formed between tile on a floor of the shower and a bottom edge of a drain cover of the wall drain assembly. The drain cover can be configured to be adjustable and removable from a drain body of the wall drain assembly. The drain cover can be implemented to cover a front of the drain body above the slit. The drain cover can be configured to receive tile or other wall covering material thereon visually permitting the drain cover to blend with tile (or other decorative fascia) of the associated wall. In one instance, magnets can be implemented to removably couple the drain cover to the drain body and can comply with plumbing and building codes. In another instance, the drain cover can be friction fit to coupling members secured to the drain body.

[0026] The wall drain assembly can be coupled to a backer board in a shower installation. An upper vertical flange of the wall drain assembly can interact with the backer board to secure the drain body in place. More specifically, the upper vertical leg can be implemented to prevent the backer board from being weak and bending above the drain body. As previously mentioned, the wall drain assembly can be configured to be substantially inset into a wall of a shower stall.

[0027] In one embodiment, the wall drain assembly can include, but is not limited to, a drain body, a foam cover, coupling members, and a drain cover. Of note, a portion of the drain body can be designated for a waterproofing membrane to be attached thereto. As can be appreciated, a waterproofing membrane can be secured to the drain body after installation of the drain body and before tile is laid. In some instances, a waterproofing membrane can be pre-attached to the drain body and be a part of the drain body. The drain body can be configured to be partially inserted into a framing of a wall. As will be shown, the wall drain assembly can include a means for removably securing the foam cover and the drain cover to the drain body.

[0028] In a typical installation, the foam cover can be secured to the drain body during installation, and then the drain cover (having tile or other decorative fascia) can be secured to the drain body after installation is complete. Of significant note, the foam cover can be implemented to determine a proper spacing for an opening (e.g., a slit) between a bottom of the drain cover and tile installed on a floor of the shower stall. More specifically, the foam cover can be implemented during installation until a final completion of removably coupling the drain cover to the drain body. As can be appreciated, this can allow for the foam cover to determine a proper spacing of the drain cover prior to the drain cover being installed.

[0029] In one embodiment, the foam cover can include a protrusion and slots for accessing fasteners of the coupling member. The foam cover can provide 3 different benefits. First, the foam cover can prevent debris from getting into a p-trap during construction. Second, the foam cover can ensure correct placement of the drain cover for a slot left for waterflow (e.g., approximately ⅜ gap between bottom of drain cover and tile). Third, the foam cover can provide a clear border for the wall tile to be butted to so that the drain cover fits over the drain body and no guessing may be necessary. As will be described hereinafter, the foam cover can include a plurality of slots that align with fastener slots of the coupling members.

[0030] In one embodiment, the drain body can typically include a first vertical leg, a horizontal upper flange extending in a first direction from a top edge of the first vertical leg, a horizontal lower flange extending in a second opposite direction from a bottom edge of the first vertical leg, and a second vertical leg extending up from a distal edge of the horizontal upper flange. The second vertical leg can be configured to interface with a backer board.

[0031] The first vertical leg can include a peripheral section and a middle section. The peripheral section can include pilot holes and be configured to have a waterproofing membrane attached thereto. The middle section can include pilot holes for attaching the coupling members and a drain outlet for coupling to a drain pipe. The middle section can be recessed and extend back from a face (or front plane) of the first vertical leg. The drain outlet can be configured to couple to a preexisting drain pipe for removal of water from the shower stall. In one instance, the first vertical leg can include ports (or pilot holes) for receiving fasteners therethrough for coupling to framing of a wall. Typically, the ports can extend back as far as the horizontal upper flange extends.

[0032] The second vertical leg and the horizontal upper flange can be configured to interface with the backer board. In some instances, the drain body can be secured to a frame of the wall. The backer board can then be secured over the second vertical leg of the drain body where the drain body may not be directly coupled to the backer board. The foam cover can be sized to protect the middle section during installation of the drain body and to properly position the coupling members above a tile laid over the horizontal lower flange. As can be appreciated, the wall drain assembly can make it easy to adjust and correct imperfections in an original installation of wall tile around the drain and on the drain cover by being able to move the drain cover after tiling and installation up and down and to the sides.

[0033] Typically, the drain body can include the drain outlet located in a middle of the drain body. The drain outlet can include an opening in a face of the drain body extending from the horizontal lower flange up towards the horizontal upper flange. The drain outlet can extend down past the horizontal lower flange to engage a drain pipe.

[0034] A top surface of the horizontal lower flange and a portion of the first vertical leg can be configured to be tiled over. Of note, the foam cover can be implemented during installation of the drain body to provide an opening between the drain cover and a top surface of tile laid over the horizontal lower flange. In one example, the middle section of the drain body may include two pairs of guide members for guiding coupling members vertically. The two pairs of guide members can ensure the coupling members stay oriented correctly while moving along the guide members. In one example embodiment, the coupling members can include magnets for magnetically coupling to the drain cover.

[0035] Of note, the drain cover can be removably coupled to the coupling members that can interface with the guide members of the drain body. Of significant note, the foam cover can be used during installation to ensure that the drain cover will be located at a proper height when coupled to the coupling members. For instance, the foam cover can be used to sit on top of tile installed over the horizontal lower flange and the coupling members can be moved to this position along the guide members and secured thereto. When the foam cover is removed and the drain cover is installed, a proper gap between a bottom of the drain cover and a top of the tile can be set by a location of the coupling members.

[0036] In one embodiment, the drain cover can include a magnetic strip oriented horizontally and spanning a width of the drain cover. The magnetic strip can be configured to magnetically couple to the coupling members. In one example, the magnetic strip can be a stainless-steel strip. The front face of the drain cover can be configured to be tiled over. As shown, the drain cover can include a ribbed surface on the front. The back of the drain cover can include protrusions spanning a width of the drain cover to interface with the coupling members.

[0037] The coupling members can be implemented to locate the drain cover in a proper position. More specifically, the coupling members can be set to a proper height in the drain body whereby when the drain cover is installed, the drain cover can be at the appropriate height. The drain cover can couple to the coupling members via magnets. In one instance, the drain cover can include guide protrusions that can interface with the guide members of the drain body to keep the coupling members oriented correctly. Further, this can allow for the coupling members to move up and down in the guide members and keep a proper spacing between the two coupling members. Fastener slots, located close to either side of the drain cover, can extend for most of a height of the drain cover to allow for coupling to the drain body.

[0038] As previously mentioned, the drain body can include pilot holes located proximate each guide member for receiving a fastener. The pilot holes can be used to secure the coupling members to the drain body. More specifically, a fastener can be passed through the fastener slots of the coupling member to engage the pilot hole and secure the coupling member thereto. As can be appreciated, by having the fastener slot elongated, the coupling member can be moved up and down and still be able to access the pilot holes.

[0039] In one instance, the coupling members can each be defined by a substantially rectangular cuboid having a top face, a bottom face, a front face, a back face, a right side face, and a left side face. The top face can be parallel to the bottom face and directly above the bottom face. The front face can be a vertical rectangle that connects a front edge of the top face down to the bottom face. The back face can be a vertical rectangle at an opposite edge of the top face and parallel to the front face. The left side face can be a vertical rectangle along a left edge of the top face down to the bottom face. The right side face can be a vertical rectangle along a right edge of the top face down to the bottom face and parallel to the left side face.

[0040] In another embodiment, the drain body can include, but is not limited to, a base flange and a vertical member. The vertical member can extend up from a back edge of the base flange. The base flange can include a drain outlet that extends down from a bottom of the base flange. The drain outlet can be configured to mate with a drain pipe in a shower stall. A portion of the drain outlet can extend up with the vertical member. The vertical member can include a peripheral section and a middle section. The peripheral section and the middle section can include a plurality of pilot holes. The pilot holes located in the peripheral section can be implemented to secure the drain body to framing of a shower stall. The pilot holes located in the middle section can be implemented to receive fasteners to couple the pair of coupling members to the drain body. As shown, the middle section can have a generally rectangular shape when viewing from the front. The peripheral section can outline the middle section and provide a surface for a waterproofing membrane to attach to the drain body. The drain outlet can extend below the bottom surface of the base flange in a substantially hollow cylindrical shape. The drain outlet can extend up into the middle section of the vertical leg in a substantially semi-conical shape. As can be appreciated, the portion of the drain outlet located above the base flange can be implemented to guide fluids to an opening of the drain outlet.Terminology

[0050] Referring to FIG. 1, a block diagram of a first embodiment 100 of a wall drain assembly is illustrated. The first embodiment wall drain assembly 100 can be implemented to be installed in a wall of a shower stall. Further, the wall drain assembly 100 can implement a cover for installation that can be discarded after installation. The installation cover can be configured to block debris from entering a drain opening of the wall drain assembly and set a slot height for a final drain cover based on tile height of the shower stall floor. Typically, the first embodiment drain assembly 100 can include a drain body manufactured from a rigid plastic.

[0051] The wall drain assembly 100 can include, but is not limited to, a drain body 102, a foam cover 104, a pair of coupling members 106, and a drain cover 108. The drain body 102 can be configured to be inset into a wall of a shower stall. The foam cover 104 can be implemented to block debris from entering a drain pipe as the drain wall assembly 100 may be installed. Further, the foam cover 104 can be implemented to set a proper height for the pair of coupling members 106 such that a gap is provided between a bottom of the drain cover 108 and tile on a floor of the shower stall when fully installed. The pair of coupling members 106 can be configured to move in an up and down direction to lower or increase a height of the drain cover 108 in relation to a floor of the shower stall. The drain cover 108 can be friction fit to the pair of coupling members to provide an aesthetic cover of the drain body 102.

[0052] Referring to FIGS. 2A-2B, various views of the drain body 102 are illustrated. As is generally shown in the figures, the drain body 102 can be defined by a horizontal lower flange 110, a first vertical leg 112, a horizontal upper flange 114, and a second vertical leg 116. The first vertical leg 112 can extend between the horizontal lower flange 110 and the horizontal upper flange 114. The horizontal lower flange 110 can extend in a first direction from a front edge of the first vertical leg 112 and the horizontal upper flange 114 can extend in a second direction from a back edge of the first vertical leg 112. The second vertical leg 116 can extend up from a distal edge of the horizontal upper flange 114.

[0053] The drain body 102 can include a drain outlet 120 and a plurality of pilot holes 122. The first vertical leg 112 can be defined by a peripheral section 112′ and a middle section 112″. The peripheral section 112′ can surround the middle section 112″ and provide a surface for a waterproofing membrane to attach thereto. As shown, a couple pilot holes 122 can be located on the peripheral section 112′ and can be implemented to secure the drain body 102 to framing of a shower stall. The middle section 112″ can be configured to include the drain outlet 120 and a first set of the plurality of pilot holes 122′. The middle section 112″ can be offset from a front plane of the first vertical leg 112. The drain outlet 120 can be configured to couple to a drain pipe in a shower stall. As shown, the drain outlet 120 can extend up from the lower horizontal flange 110 into the first vertical leg 112. The plurality of pilot holes 122 can each be configured to receive a fastener therein. Typically, the pair of coupling members 106 can be moveably coupled to one or more of the plurality of pilot holes 122′ in the middle section 112″ via a fastener. A first set of the plurality of pilot holes 122 can be configured to mate the drain body 102 to framing of a shower stall. A second set of the plurality of pilot holes 122′ can be implemented to couple the coupling members 106 to the drain body 102.

[0054] When installed in a shower stall, the drain outlet 120 can be attached to a drain pipe (not shown). The portion of the drain outlet 120 below the lower horizontal flange 110 can typically be located beneath flooring (e.g., tile) in the shower stall. The drain outlet 120 can extend up from the lower horizontal flange 110 and back from the vertical leg 112 to ensure the drain body 102 may be installed while minimally protruding from a wall of the shower stall. The portion of the drain outlet 120 in the middle section 112″ can be configured to direct fluids to the opening of the drain outlet 120.

[0055] Referring to FIGS. 3A-3B, various views of the foam cover 104 are illustrated. FIG. 3A includes a front perspective view of the foam cover 104. FIG. 3B includes a front view of the foam cover 104. Of note, the foam cover 104 can include a pair of slots 125 that can allow a fastener to pass through and couple the foam cover 104 to the drain body 102. Further, the slots 125 allow for a location of the foam cover 104 in relation to a top of the horizontal lower flange 110 of the drain body 102. The foam cover 104 can be implemented during installation of the wall drain assembly 100 to help ensure that debris does not enter into a drain pipe during installation. Further, the foam cover 104 can be implemented to set a height of the coupling members 106 for installation of the drain cover 108 after installation is complete.

[0056] Referring to FIGS. 4A-4C, various views of one example embodiment of a coupling member 106 are illustrated. As previously mentioned, the pair of coupling members 106 can be secured to the drain body 102 via the pilot holes 122 and fasteners. FIG. 4A includes a top view of the coupling member 106. FIG. 4B includes a perspective view of the coupling member 106. FIG. 4C includes a side view of the coupling member 106.

[0057] The coupling member 106 can typically be a substantially solid rectangular cuboid having a top face, a bottom face, a front face, a back face, a right side face, and a left side face. The coupling member 106 can include a pair of countersunk slots 130. An opening of the pair of countersunk slots 130 can extend between the top face and the bottom face of the coupling member 106. The pair of countersunk slots 130 can extend from proximate the front face toward the back face. As shown, one slot can be located proximate the right side face and one slot can be located proximate the left side face. The pair of countersunk slots 130 can have a length approximate to a width of the coupling member 106. The coupling member 106 can further include grooves 132 on a front face and a back face of the coupling member 132. A first groove can be on the front face extending between the right side face and the left side face and a second groove can be on the back face extending between the right side face and the left side face. Of note, the grooves 132 can be implemented to interface with a portion of the drain cover 108.

[0058] Referring to FIGS. 5A-5C, various views of the drain cover 108 are illustrated. FIG. 5A includes a top perspective view. FIG. 5B includes a bottom perspective view. FIG. 5C includes a front view. In one embodiment, the drain cover 108 can include a top plate 140 and a pair of engagement members 142 that can extend down from the top plate 140. As can be appreciated, the engagement members 142 can be spaced to engage exterior sides of the pair of coupling members 106. More specifically, the engagement members 142 can be configured to frictionally engage the grooves 132 of the pair of coupling members 106.

[0059] As shown, the engagement members 142 can typically run an entire length of the top plate 140. It is to be appreciated that a length of the engagement members 142 can be altered without exceeding a scope of the present invention. In a typical implementation, the drain cover 108 may be made from a single piece of material where the engagement members 142 are integral with the top plate 140. In one instance, the engagement members 142 may be manufactured separately from the top plate 140 and later coupled to the top plate 140. It is to be appreciated that the top plate 140 and the engagement members 142 may be manufactured from different materials.

[0060] As shown, the top surface 140 of the drain cover 108 can be ribbed. The ribbed surface can allow for tile to be securely attached to the drain cover 108. An overall depth and spacing of the ribs can be altered dependent on specific applications. Embodiments are contemplated where a top surface of the drain cover 108 can be flat and not ribbed. Typically, the top plate can be sized to cover an entirety middle section of the drain body 102.

[0061] Referring to FIG. 5C, a cross-sectional shape (via the front view) of the engagement members 140 is illustrated. Of note, the engagement members 140 can include a round bulge (e.g., semi-spherical) on a lower interior side of the engagement member to engage with the grooves 132 of the coupling members 106. As shown, each of the engagement members 140 can include the bulge which can engage with both grooves 132 of the coupling members 106.

[0062] Referring to FIGS. 6A-6B, various views of a coupling member 106 interfacing with the drain cover 108 are illustrated. FIG. 6A incudes a front view of the coupling member 106 coupled to the drain cover 108. FIG. 6B includes a bottom perspective view of the coupling member 106 engaged with the drain cover 108. As shown, the round bulges of the engagement members 142 can interface with the grooves 132 of the coupling members 106. In a typical implementation, the coupling members 106 can be secured to the drain body 102 and then the drain cover 108 can be pressed onto the coupling members 106 to secure the drain cover 108 to the drain body 102.

[0063] The slots 130 of the coupling members 106 can be countersunk to ensure that the fasteners do not protrude above a top face of the coupling members 106. If the fasteners were to be above the top surface, they may interfere with the drain cover 108 securing to the coupling members 106.A Second Embodiment of a Wall Drain Assembly

[0064] Referring to FIG. 7, a block diagram of a second embodiment 200 of a wall drain assembly is illustrated. The second embodiment wall drain assembly 200 can be implemented substantially similar to the first embodiment wall drain assembly 100. However, instead of implementing a plastic for the drain body, the second embodiment drain assembly 200 can include a drain body manufactured from metal. As will be described hereinafter, the components of the second embodiment wall drain assembly 200 can be substantially similar to the first embodiment wall drain assembly 100.

[0065] As shown, the wall drain assembly 200 can include, but is not limited to, a drain body 202, a foam cover 204, a pair of coupling members 206, and a drain cover 208. The drain body 202 can be configured to be installed in a wall of a shower stall. The foam cover 204 can be used during installation of the drain body 202 and construction of the shower stall. The pair of coupling members 206 can be implemented to couple the foam cover 204 and the drain cover 208 to the drain body 202. The coupling members 206 can be moveably coupled to the drain body 202 in an up and down movement.

[0066] Referring to FIGS. 8A-8C, detailed diagrams of the drain body 202 are illustrated. FIG. 8A can include a perspective view of the drain body 202. FIG. 8B can include a front view of the drain body 202. FIG. 8C can include a side view of the drain body 202. The drain body 202 can include, but is not limited to, a base flange 210 and a vertical member 212. The vertical member 212 can extend up from a back edge of the base flange 210.

[0067] The base flange 210 can include a drain outlet 214 that extends down from a bottom of the base flange 210. The drain outlet 214 can be configured to mate with a drain pipe in a shower stall. A portion of the drain outlet 214 can extend up with the vertical member 212.

[0068] The vertical member 212 can include a peripheral section 212′ and a middle section 212″. The peripheral section 212′ and the middle section 212″ can include a plurality of pilot holes 216. The pilot holes 216 located in the peripheral section 212′ can be implemented to secure the drain body 202 to framing of a shower stall. The pilot holes 216′ located in the middle section 212″ can be implemented to receive fasteners to couple the pair of coupling members 206 to the drain body 202. As shown, the middle section 212″ can have a generally rectangular shape when looking from a front view (as shown in FIG. 8B). The peripheral section 212′ can outline the middle section 212″ and provide a surface for a waterproofing membrane to attach to the drain body 202.

[0069] As shown in FIG. 8C, the drain outlet 214 can extend below the bottom surface of the base flange 210 in a substantially hollow cylindrical shape. The drain outlet 214 can extend up into the middle section 212″ of the vertical member 212 in a substantially semi-conical shape. As can be appreciated, the portion of the drain outlet 214 located above the base flange 210 can be implemented to guide fluids to an opening of the drain outlet 214.

[0070] Of note, the foam cover 204, the pair of coupling members 206, and the drain cover 208 can be substantially similar to the first embodiment foam cover 104, pair of coupling members 106, and drain cover 108. Further, the second embodiment components 204-208 can be implemented substantially similar to the first embodiment components 104-108.

[0071] Referring to FIGS. 9A-9B, various front views of the second embodiment wall drain assembly 200 are illustrated. Of note, and as shown, the location of the drain cover 208 can be moved up and down within the middle section 212″ of the drain body 202. In FIG. 9A, the drain cover 208 can be located in an upper position. In FIG. 9B, the drain cover 208 can be located in a lower position. As can be appreciated, the pair of coupling members 206 can be moved up and down and then secured in place during installation with the foam cover 204. The foam cover 204 may then be removed and the drain cover 208 can be installed.Alternative Embodiments and Variations
