RELATED APPLICATION

This application claims priority to U.S. Provisional Application Ser. No. 62/320,535 filed Apr. 10, 2016.

FIELD OF THE INVENTION

The present invention relates to bathroom fixtures and particularly to the push-button and/or motion sensor flush actuators associated with manual flushing of toilets.

BACKGROUND OF THE INVENTION

Toilets come in a large variety of shapes and sizes, but all manually flushable toilets tend to have relatively short, flush actuators, typically in the nature of levers, buttons or knobs, positioned on the side, front or top of the toilet, that fit closely adjacent to the toilet. Top flush actuators tend to be even or level with the top of the tank and operate by pushing inward toward the toilet tank. Side flush actuators tend to be large buttons or levers or knobs that one presses or turns or pulls down, and front flush actuators tend to be positioned near the top of the toilet, adjacent the toilet tank lid or top, that one pulls down. Generally, the pressing, rotating or turning of the flush actuator produces a levered rotation of the flush rod located in the tank, which in turn lifts a chain associated with a flapper or other flushing mechanism to release water from the tank into the toilet bowl. Reaching the flush actuator typically or often requires a person to stretch, twist or reach over the toilet, which can be difficult and impractical for users having a limited range of motion, including handicapped and elderly persons, as well as young children, or when the toilet is installed in a tight or small space. Easier mechanisms for activating a toilet flush are needed.

U.S. Pat. No. 2,908,915 (Holl) describes a flushing device with a lever connected to a water supply line through an intervening rod. A chain is secured at one to the toilet's flush handle with a strap. At the other end, the chain is attached to an intermediate point of the lever in a keyhole slot accepting a bead from the chain.

U.S. Pat. No. 8,726,427B1 (Padron) relates to a commode flushing handle with a cylindrical rod that is rotatably attached to a toilet at the seat hinges and bent at a right angle to form a handle with a spring clip. The other end of the cable is attached to a bracket mounted on the rod. When the rod is raised, the cable is pulled downward to flush the toilet.

U.S. Pat. No. 6,718,562B1 (Saragas) discloses a foot-operated toilet flushing device that has a pivot assembly mounted to the floor. A lever has a foot pedal at one end and, at the other end, is rotatably connected to the pivot assembly. A linkage assembly connects the flush handle to the pivot assembly.

There is a need for a versatile extender for push-button and/or motion sensor flush actuators.

It will be apparent to those skilled in the art that other embodiments of the sleeve 22 are possible without departing from the spirit of the present invention.

The fulcrum member 12 shown in FIG. 4 has an opening 34 for allowing an extender head 26 to engage a push-button and/or motion sensor actuator 6 for an actuator mounted on a front face of a toilet, as shown in FIG. 2.

The fulcrum member 12 may have a cushioning material (not shown) on all or a portion of the underside of the fulcrum member 12, so as to reduce scratching, marring or otherwise damaging the toilet 4 when in position.

The fulcrum member 12 may be adjustable in length (not shown) to retrofit flush actuators for toilets having different distances between the rim of a toilet tank and the push-button and/or motion sensor actuator 6.

The lever arm 16 is connected to the rigid extension rod 14 at an angle in a range of from about 80 degrees to 120 degrees. Preferably, the angle is in a range from about 85 degrees to 110 degrees. Most preferably, the lever arm 16 is connected to the rigid extension rod 14 at an angle of 90 degrees.

In the embodiment shown in FIGS. 1 and 2, the lever arm 16 is integrated with the rigid extension rod 14. An integrated rigid extension rod 14 and lever arm 16 is shown in FIG. 5a for a top mounted push-button and/or motion sensor. Another embodiment of an integrated rigid extension rod 14 and lever arm 16 is shown in FIG. 6a for a front-mounted push-button and/or motion sensor. In the FIG. 5a and FIG. 6a embodiments, the integrated rigid extension rod 14 and lever arm 16 are threaded at one end for connecting to the extender head 26 and at the other end for receiving the lever handle 18.

Alternatively, the rigid extension rod 14 and lever arm 16 may be provided in a two-piece set for a kit of the present invention. For example, FIG. 5b illustrates a two-piece set, with a lever arm 16 having an integrated elbow 38 for connecting to a rigid extension rod 14 for a top mounted push-button and/or motion sensor. FIG. 6b illustrates another two-piece embodiment with a lever arm 16 having an integrated elbow 38 for connecting to a rigid extension rod 14 for a front-mounted push-button and/or motion sensor.

FIGS. 7a-7c illustrate one embodiment of an extender head 26 suitable for a push-button and/or motion sensor flush actuator 6 mounted on a top face of the toilet 4, for example as shown in FIG. 1. FIGS. 8a-8b illustrate another embodiment of an extender head 26 suitable for a push-button and/or motion sensor flush actuator 6 mounted on a front face of the toilet 4, for example as shown in FIG. 2. The extender heads 26 shown in FIGS. 7a-7c and 8a-8b have a hole 38 for connection to the rigid extension rod 14.

The extender head 26 may have a cushioning material (not shown) on the underside of the extender head 26, so as to reduce scratching, marring or otherwise damaging the toilet 4 when in position. Alternatively, the extender head 26 may be made of a material that would reduce scratching, marring or otherwise damaging the toilet 4.

The extender head 26 may have a flat face for contacting the push-button flush actuator 6. Alternatively, the extender head 26 may have a stepped face for contacting a dual push-button flush actuator 6, the dual push-button flush actuator capable of activating a flush of two different amounts of water. It will be apparent to those skilled in the art how to contour the face of the extender head 26 to complement the contours of a dual push-button flush actuator 6.

The extender head 26 may be installed by providing a fixative, for example, without limitation, double-sided tape, to hold the extender head 26 in position on a face of a push-button flush actuator 6. For a motion sensor actuator 6, the extender 10 of the present invention is installed to allow the extender head 25 to be moved over the motion sensor actuator 6, thereby engaging the actuator to activate the flush mechanism.

FIG. 9 illustrates an embodiment of a decorative lever handle 18 for the extender 10 of the present invention. Alternatively, the lever handle 18 may be a flat plate or bowl-shaped for assisting a user who is not able to grab a lever handle 18.
