Abstract

A flexible drive mechanism for a flushing apparatus actuated by movement of a flush handle via an actuation element. The drive mechanism includes a housing and flexible drive system in the housing, the flexible drive system including an actuating element operable to move the flush handle between a non-actuating position and a full stop actuating position. The flexible drive system is maintained in substantial continuous contact with the flush handle as the flush handle moves to its full stop position, and the flexible drive system continues to operate without stalling after the flush handle reaches its full stop position as a support plate for the motor and flexible drive system changes position to provide flexure or 'give' between the flush handle and the actuating element to prevent stalling of the flexible drive system. In another embodiment, the flexible drive system includes a cam having a main body part and a flexible body part, with a bias element between the body parts. As the cam rotates beyond the full stop position of the flush handle, the flexible body part moves towards the main body part against the force of the bias element, providing the flexure or 'give' which allows continued rotation of the cam through a full 360 degree cycle after the flush handle has reached its full stop position.
