РЕФЕРАТ (Abstract)

The device of the present invention comprises a limiting face configured to limit a movement of a stop arm of a toilet flush system actuator unit, that may be mounted to a toilet flush valve body by at least one retention piece. A fulcrum piece may also be provided, the fulcrum piece including a fulcrum hole adaptably sized to receive a fulcrum pin of a toilet flush system actuator unit, such that when the device is installed on a broken toilet flush valve the device will substitute, or provide support, for the support arms with fulcrum holes and stop tab for the toilet tilt valve.

ФОРМУЛА ИЗОБРЕТЕНИЯ (CLAIMS)

We claim:

1. A fulcrum element for repair of a toilet flush system, comprising: at least one fulcrum piece associated with the fulcrum element, the at least one fulcrum piece having a fulcrum hole adaptably sized to receive a fulcrum pin of a toilet flush system actuator unit, and at least one retention piece configured to mount the fulcrum element to a toilet flush valve body and wherein the fulcrum element is formed from a single lamina sheet, comprising: two retention arms each formed from the ends of the lamina sheet, the retention arms each comprising an inner wall, wherein each inner wall is parallel and facing an opposing inner wall, and wherein a distal portion of each inner wall extends away from a body portion of the lamina sheet in a manner such that each distal portion is perpendicular to the fulcrum element and parallel to each other; an outer wall, a rear edge, and a front edge, the front edge terminating at an end of the lamina sheet; and a bridge surface formed from a middle portion of the lamina sheet, wherein the fulcrum element is configured to be mounted on the toilet flush valve body by sliding the two retention arms over respective support arms of the toilet flush valve body, and is further configured such that when the fulcrum element is mounted on the toilet flush valve body each of the two retention arms substantially surround a portion of a respective support arm and a face of the bridge surface is substantially flush against a portion of a bridge material of the toilet flush valve body disposed between the two support arms and the bridge material is substantially tightly sandwiched between the face of the bridge surface and the front edge of each retention arm, and wherein each distal portion of each inner wall comprises a fulcrum hole, each fulcrum hole being aligned with an opposing fulcrum hole and adaptably sized to receive a fulcrum pin of a toilet flush system actuator unit.

2. The fulcrum element of claim 1, wherein the fulcrum element is configured to be mounted on the toilet flush valve body by sliding two of the at least one retention piece over respective support arms of the toilet flush valve body, and is further configured such that when the fulcrum element is mounted on the toilet flush valve body an inner wall of the at least one retention piece is configured to closely follow a profile of a portion of a respective support arm of the toilet flush valve body to provide fulcrum holes for receiving respective fulcrum pins of the toilet flush system actuator unit.

3. The fulcrum element of claim 1, wherein the at least one retention piece is configured to grip a portion of at least one support arm of a toilet flush valve body to mount the fulcrum element to a toilet flush valve body.

4. The fulcrum element of claim 3, further comprising: a flange associated with the fulcrum piece, the flange being configured to enclose at least a portion of the fulcrum pin when the fulcrum pin is received into the fulcrum hole.

5. The fulcrum element of claim 1, further comprising: a limiting face configured to limit a movement of a stop arm of a toilet flush system actuator unit.
