  • Patent number: 10017933
    Abstract: An elongate linear drain for a shower includes an elongate, channel-shaped drain body, an elongate, channel-shaped extension that is connectable to either end of the drain body, elongate inserts that are nested within the drain body and the extension, and end walls that cap the ends of the drain body and the ends of the extension. Mounting members are formed along an outboard side of each sidewall of the drain body and the extensions and the mounting members are engaged by float sticks to facilitate the sloping of the floor that leads to the linear drain. Height adjustment screws formed in the respective bottom walls of the drain body and extensions enable height adjustment of the inserts. This enables the tile that overlies the shower floor to be flush with the tile that overlies the insert.

  • Patent number: 8857109
    Abstract: A tile-ready base includes a triangular top wall disposed in a horizontal plane when the base is secured to a corner. A first side wall depends from a first edge of the top wall and abuts a first vertical wall of a building. A second side wall depends from a second edge of the top wall and abuts a second vertical wall of the building. A front wall depends from a front edge of the triangular top wall and interconnects respective forward ends of the first and second side walls. Structural support ribs underlie the top wall and enhance the structural integrity of the base. Concavities are formed in the top wall in close proximity to the first and second side walls. Each concavity receives a screw and facilitates attachment of the base to the corner. The base is installed and tiled with no delay between installation and tiling.

  • Patent number: 8261511
    Abstract: A tool for changing a substantially level or unlevel floor to a sloped floor having a predetermined slope includes a float stick formed of a rigid, cuttable material so that it can be cut to length as required by the size of the floor. The float stick has a sloped top edge and a flat bottom edge. The sloped top edge slopes downwardly from a proximal end to a distal end of the float stick at a predetermined slope per linear unit. A spirit level is mounted to the float stick and is calibrated so that its bubble is centered when the flat bottom edge is level. At least one vertical bore is formed in the float stick and an adjustment peg is disposed within the bore. The adjustment peg is extended from the bore to level the flat bottom edge of the float stick on an uneven floor.

  • Patent number: 7793378
    Abstract: A combination tool having utility in tile installation procedures includes a wide blade adapted to remove excess grout and caulk in relatively large quantities, a four-armed cement remover and grout joint spacer, a spherical grout packer and a ā€œVā€-shaped grout and caulk profiler adapted to be secured to a hollow handle in varying combinations. In a first embodiment, the wide blade is attached to a first end of the handle and the four-armed cement remover-grout joint spacer and the spherical packer are releasably secured to a second end of the handle. A second embodiment includes the blade at the first end and the ā€œVā€-shaped profiler at the second end in lieu of the cement remover and packer. The hollow handle provides a storage compartment for additional packers. The tool may be made of material that floats in water. The handle may also have a non-hollow web construction.

  • Patent number: 7257926
    Abstract: A method for installing tiles includes the steps of positioning a base in overlying relation to cementitious material. First and second spacer arms are formed on the base in normal relation to one another. Preselected corners of four tiles are positioned in overlying relation to the base and are spaced apart from one another by the spacer arms. A post having ratchet teeth is formed integrally with the base at the center of the base. A disc receives the post and a pawl formed in the disc prevents displacement of the disc away from the base. The disc is positioned in overlying relation to the four corners of the tiles so that it overlies and holds the tiles level between the base and the disc. After curing of the cementitious material, an installer twists the disc in a plane parallel to the tiles until the post breaks off.

  • Patent number: 7210188
    Abstract: A sponge for cleaning grout that occupies the concave spaces between tiles has a cleaning surface that includes a plurality of rows of elongate convexities. In a first embodiment, the convexities are linear in configuration, are disposed in parallel relation to one another, and the space between the convexities is flat. In a second embodiment, the space between the parallel, linear convexities is occupied by secondary convexities that have less height than the primary convexities. In a third embodiment, the convexities are non linear and non-parallel. In all embodiments, the convexities may be aligned with the concave grooves between tiles or positioned at a right angle to the grooves. In both orientations, the convexities extend into the concavities and clean the grout between the tiles.

  • Patent number: 7070667
    Abstract: Tiles are installed on a vertical wall by employing an elongate, straight device that includes a spirit level. The device is positioned in overlying relation to the wall and rotated until it is horizontal as indicated by the spirit level. A plurality of longitudinally spaced and vertically staggered slots is formed in the device. Each slot receives a fastener so that the device can be secured to studs behind the wall. A row of tile supported by the device is then installed on the wall. The fasteners are removed after the tile installation is complete so that the device can be moved and re-used. Opposite ends of the device are configured to releasably engage a device of the same structure so that multiple devices can be linked together. An alternative embodiment is notched along its extent to provide utility in the context of convex and concave walls.

  • Patent number: 6568140
    Abstract: An apparatus and method for making a sloped floor includes a plurality of elongate arms disposed in radial array relative to a drain. Each arm has a common height along its extent. The radially innermost end of each arm is positioned near or connected to the drain. In a first embodiment, the radially innermost end of each arm is pivotally connected to an adapter that is connected to a center ring that circumscribes the drain. In a second embodiment, each arm is positioned at an incline by an adapter that rigidly joins the arm to the center ring. In a third embodiment, the arms are of shallow construction and are removed after the concrete has been poured. A mounting strip secured to the shower wall may support the radially outermost end of each arm. In all embodiments, the concrete is worked so that it is flush with the uppermost edge of each elongate arm.

  • Publication number: 20030089059
    Abstract: A shower curb is built by stacking two or three horizontally disposed 2″×4″ boards in a vertical stack and covering them with a shower liner. A three-sided frame having upstanding parallel front and back walls that depend from and are perpendicular to a top wall is placed over the liner and the boards. The frame is lattice-like and has a large plurality of openings formed in it. A cementitious material is applied to the frame so that the material enters into the openings and is screeded until it completely covers the boards and is flush with the frame. Ceramic tiles are then laid in overlying relation to the resulting structure. In a second embodiment, the top wall of the frame is pitched toward the shower to provide drainage.

  • Patent number: 6155015
    Abstract: A method for making a floor that slopes toward a drain includes the steps of enclosing a predetermined area of a flat support surface around the drain with upstanding border members, positioning an annular ring in closely spaced, concentric relation around the drain, arranging a plurality of straight form members in radial relation to the drain, connecting a radially innermost end of each form member to the annular ring so that the top edge of each form member is spaced downwardly from the plane of the drain by a distance equal to a tile thickness, and positioning an outermost end of each form member in abutting relation to the border member. Each form member has a height at its innermost end that is less than a height of its outermost end A cementitious material is poured into the predetermined area and the material is made flush with the respective top edges of the form members. An auxiliary form member is attachable to a trailing end of each form member to increase the versatility of the method.
