Abstract: A wall-entry bathtub includes a basin, a shell defining an entryway to allow access into the basin, and an entry wall movable between a lowered position and a raised position, wherein the entry wall is substantially clear of the entryway in the lowered position and at least partially blocks the entryway in the raised position. The bathtub also includes first and second entry wall position sensors configured to sense the position of the entry wall and a controller in electronic communication with the first and second entry wall position sensors, wherein the controller is configured to control components of the bathtub based at least in part on the position of the entry wall.

Abstract: A wall-entry bathtub includes an entry wall movable between a raised position and a lowered position to provide convenient ingress and egress. A handle assembly is coupled to a pair of latches and brackets to selectively restrain the wall-entry bathtub in the raised position. A counterweight assembly is coupled to the entry wall and reduces the force required to move the entry wall between the lowered and raised positions. The entry wall also includes a seal member that is expandable to inhibit water from leaking past the entry wall when the wall-entry bathtub is in use. Dual drains are provided to reduce the time required to drain water from the wall-entry bathtub. And, a controller, in combination with a variety of sensors, applies predetermined logic to control the water filling, entry wall sealing, and water draining of the wall-entry bathtub.

Abstract: A bathtub rim assembly is disclosed that includes a support structure that is capable of engaging a rim of a bathtub to prevent substantial deformation and damage to a cantilevered ledge of the bathtub. The rim assembly further includes a skirt that obscures the support structure to maintain a unitary appearance of the overall bathtub assembly.

Abstract: Disclosed are trap valve assemblies for controlling flow from a toilet bowl to a trap way. In one form there is a cartridge unit positionable immediately below a toilet bowl discharge outlet. It has a pivotable gate in a form of a spherical segment. The gate has an eccentric pivoting motion so that it can swing from an open position to a blocking/closing position in which it fully contacts a sealing gasket. The spherical segment has a leading edge which is approximately between +40° and ?40° from vertical when the gate is in an open position, to minimize the energy required to close the gate. In another form a ball and socket connection to the gate valve facilitates sealing.

Abstract: A seat assembly for sliding along opposing rims of a bathtub is disclosed. The seat assembly includes a seat member, a friction element affixed to the seat member so as to extend under the seat member, and a flexible slider affixed to the seat member so as to also extend under the seat member. The slider and friction element are positioned and configured so that in a first state, if the seat member is positioned on the opposing rims without additional weight on the seat member, the slider holds the friction element up off a rim while facilitating sliding of the seat member along a rim. In a second state, if the seat member is positioned on the opposing rims with a human weighing over 50 pounds sitting on the seat member, the friction element can contact the rim and thereby impede sliding of the seat member along a rim.

Abstract: An open-ended coupler for joining a pipe to a larger opening defines a passageway having straight and angled sections. The straight section has a uniform inner diameter concentric about a centerline sized to receive the outer diameter of the pipe. The angled section has a narrow end with an inner diameter less than that of a wide end and of the straight section, and being at least as large as the inner diameter of the pipe. The angled section has an upper portion above the centerline that at least in part increases in radius from the narrow end to the wide end. A lower portion has a constant radius, at least along a line extending between the narrow and wide ends at a six o'clock position with respect to the open end of the angled section. A face groove holds an o-ring and an alignment tab fixes the rotational orientation of the coupler.

Abstract: An apparatus is provided to control a plumbing fixture, such as a whirlpool, that has electrically operated components. The apparatus has a dial that is moveable by the user into a plurality of positions to select a function of the plumbing fixture to be controlled. A unique sensor arrangement detects motion and the direction of the motion and provides a signal to a controller that changes the valve of a pointer that designates which function is presently selected. The user then presses a keypad to indicate whether the selected function is to be activated or deactivated and to control the intensity of the selected function. The signals from the keypad also are applied to the controller.
