Abstract: A toilet seat lifting system includes a foot-operated bellows connected to a hinged rod which is surrounded by a sleeve. The rod is then extended by the air produced by the bellows and the rod is attached to the toilet seat with adhesive or suction cup. The rod includes a hollow outer rod and an inner rod that is inserted within the outer rod. The outer rod is then sealed against the inner rod through an air tight seal. When the bellows is actuated, air is supplied through the bottom rod and released within the outer rod. Since the outer rod is air tight, the pressure created by the air within the rod forces a latch at the top of the outer rod to open and release the pressure. The opening of the latch in turn actuates the lifting of the toilet seat.

Abstract: The toilet foot flushing apparatus quickly converts a hand-flushed toilet to a foot-flushed toilet, without the need of tools. The included lever of the apparatus replaces the existing toilet lever, by hand. The pedal is about 1 foot in length, thereby providing sufficient leverage to the lever via the cable. The lever is attached to flush mechanism on the exterior of an existing toilet reservoir. The spring-loaded pedal returns to a position slightly above the base when released, thereby releasing lever pressure. The geared pedal to base action provides sturdy long-lived flush function. The apparatus does not require any form of floor invasion, as the base need not be mounted to the floor. The cable retainer provides length adjustment for the cable so that a plurality of toilet reservoirs and flush mechanisms can be successfully converted to foot flush.

Abstract: A novel attachment on a toilet system for a male user to raise a toilet seat (100), by depressing a pedal (30) with a foot and then releasing it, while standing well balanced on his second foot, so that he can urinate comfortably with both feet on the floor; and then to lower same seat (100) by depressing same pedal (30) and releasing it; with all these actions done with no startling noise against the water tank (104) or the toilet bowl rim. The dual operation of the same pedal (30) can provide a timely flushing of the toilet automatically when seat (100) is lowered, without hand touching any part of the toilet system. The attachment can add, with a secondary pedal (140), a hands-free flushing system that can be operated without moving toilet seat (100) when it is already in the lowered position. All manual toilet-system operations are preserved.

Abstract: In the breakdown preventive mechanism of a rotary damper, when the upper rotor is rotated in one direction, a communication path is formed between the valve body and the lower rotor, and the pressure in the pressure chamber is formed between the lower rotor and the lower housing is lowered, and rotation is easily performed. When the upper rotor is rotated in another direction, the viscous fluid does not flow between the valve body and the lower rotor, and the pressure in the pressure chamber formed between the lower rotor and the lower housing is raised. As a result, the viscous fluid pushes down the relief valve and a cage type relief valve by resisting the elastic element, and thereby prevents breakdown of the rotary damper.

Abstract: A hydraulically lifted toilet seat. A hydraulic linear actuator mounted within a lift unit rigidly attached to the toilet bowl unit utilizes utility water pressure to provide a force to lift the toilet seat. In a preferred embodiment a drive arm of the hydraulic linear actuator applies a tension force to a flexible tension element which is in turn attached to a sheave that is rigidly attached to an axle rigidly attached to the toilet seat. Actuation of the drive arm of the linear actuator causes the sheave, axel and the toilet seat to pivot about 100 to 110 degrees from a horizontal position to a raised position leaning against the toilet tank. In the preferred embodiment the flexible tension element is a nylon cord attached to the sheave through a pulley. In this preferred embodiment the hydraulic linear actuator is controlled by a spring loaded three-way valve or two two-way spring loaded valves permitting users to raise or lower the seat by temporally positioning valve handles up or down.

Abstract: The invention provides a foot operated toilet seat lifter which may be easily installed on a toilet. The universal bracket with a retained cylinder and piston is mounted to the toilet bowl by using the existing toilet seat fasteners.

Abstract: An apparatus and method for foot actuating a toilet by providing a foot pedal having an enhoused cable extending therefrom. The cable is attached inside the toilet tank to a flushing means within the tank. Upon a user stepping down on the pedal, dual components of the pedal provide for the amount of cable within the foot pedal to be increased by a factor of two relative to the pedal travel distance. This in turn provides for the cable inside of the tank to be decreased by such amount for lifting a weight and actuating the internal flushing means within the toilet tank. Upon removing the user's foot from the foot pedal, the foot pedal, cable and weight are automatically reset to a starting position allowing the toilet to be reset to its original position for reuse.

Abstract: A mechanism for raising and lowering a toilet seat in response to actuation of foot pedals. An actuation cylinder with a contained piston is connected between the toilet bowl and the toilet seat. Water from the supply line for the toilet is routed to the actuator cylinder when a seat up pedal is depressed and causes the piston to extend out of the actuation cylinder and raise the seat. Operation of a flush pedal causes the water within the actuation cylinder to drain so that the toilet seat lowers. A mechanical linkage from the flush pedal to the flush mechanism of the toilet links toilet flushing to the seat lowering action, ensuring that the seat is lowered after each flush.

Abstract: Apparatus to displace a raised toilet cover or seat member, comprising an actuator movable generally endwise toward a location defined by the raised toilet seat or cover, a mechanism within the toilet tank to urge the actuator endwise from a retracted position in response to lowering of the surface level of water in the tank, and toward that location to effect lowering of the seat or cover, the actuator thereafter being movable toward its retracted position.

Abstract: A self-contained, self-closing toilet lid includes a water reservoir formed within an upper portion of the lid. When the lid is in its vertical closed position, water from the reservoir is allowed to trickle at a predetermined rate into an activation bucket positioned within a lower portion of the lid and pivotally coupled proximate an inner peripheral edge of the lid. When a sufficient volume of water has been gravitationally transferred from the upper water reservoir to the lower activation bucket, the weight of that transferred water causes the activation bucket to pivot, which in turn actuates a release mechanism that allows the lid to hingedly move to an off-center position, permitting it to fall to its horizonatal closed position. If both the toilet lid and the seat conventionally mounted behind it are in the open position, automatic closing of the lid will push the seat to the closed position also.

Abstract: An assembly useful in directing a stream of water onto the surfaces of a toilet bowl includes a delay valve rendered operative by the lifting of the toilet seat and a bellows spring connected to be pulled in by the latching vacuum draw of the delay valve and thereafter released to displace the seat towards its lowered state.

Abstract: A device is described for automatically lowering a toilet seat. The device includes a fluid chamber with a sidewall; a replaceable insert with an arcuate inner face and parallel seat-raised and seat-lowered edges against the sidewall. A vane with a seat-attached shaft, pivotal around a horizontal axis on the opposite side of the chamber, includes a shaft-attached paddle with a flexible distal end in brushing engagement with the insert. The distance between the insert wall and the horizontal axis decreases from the seat-raised edge to the seat-lowered edge increasing the resistance to pivoting of the vane, and thereby to lowering of the toilet seat as the seat descends. Different inserts can be used for different weight seats. The device can also include an adjustable seat stop to compensate for non-level toilets.

Abstract: An automatically raised toilet seat apparatus is provided. The toilet seat apparatus includes a toilet seat portion and a pair of box portions. The body of each box portion forms a closed space which contains a liquid and defines a plurality of tank compartments. Baffles separate at least some of the tank compartments. The liquid's adaptive distribution between tank compartments facilitates the toilet seat portion's gradual displacement between lowered raised positions, biasing the toilet seat portion to one of those positions. In certain cases, a pair of shallow holes and a pair of deep holes are formed into the toilet seat portion, for adjustably receiving the box portions, depending on the size of the given toilet's water tank.
