  • Patent number: 9259124
    Abstract: A toilet adapter which allows a user to lift the lid, the seat, and flush the toilet using three dedicated pedals and their respective actuating mechanisms. The lid pedal and the seat pedal utilize a crankshaft connection to rotate adapters that grasp the lid and the seat, raising the lid and seat as the pedal is pressed. The flush pedal uses a double pivot connection to pull down on an adapter that is secured to a toilet handle. The seat pedal and the flush pedal can be lifted to activate sub assemblies. A bidet assembly and a dryer assembly are operated by lifting the seat pedal and the flush pedal, respectively, with a brace provided so that the regular functions can still be accessed by pressing down. A variation can be implemented for urinals, in which the lid and seat components are unnecessary and left out.

  • Patent number: 8286273
    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.

  • Patent number: 8096393
    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.

  • Publication number: 20080178374
    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.

  • Patent number: 7003815
    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.

  • Patent number: 6775855
    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: A unit that is used to lift a toilet seat. This unit has a base hinge with a foot pedal that uses a cable and pulley lifting system. This system lifts a movable rod of a shock-absorber device, which in turn lifts a seat bracket and the toilet seat. A removable adjustment pad, limits the travel lift distance of the toilet seat. This adjustment keeps the toilet seat on a slight tilted angle. The gravity of the seat on an angle, returns the seat when a pedal is depressed. The shock absorber device slows the returning decent of the seat back down to the bowl when the pedal is depressed. The shock absorber device resides inside a housing tube, and it rests on top of a bottom cover plate pedestal. The housing tube is attached to a base hinge. There is non-skid material on the bottom cover plate to stabilize the unit while in use.
