AI Technical Summary

Technical Problem

Existing toilet flushing mechanisms suffer from piston shaft offset or inclination due to tolerances in bearings and eccentric pressing, leading to increased friction and the need for high actuating forces.

Method used

A device with a ball joint connecting the actuating button to the pressure generator, allowing for multidirectional movement and preventing rotational or torsional forces, thereby reducing piston axial offset or inclination, and utilizing a housing with guides for linear movement of actuating components.

Benefits of technology

The solution reduces the need for high actuating forces by compensating for piston misalignment, ensuring smooth operation and efficient flushing with minimal effort.

Claims

[1] Device (1) for actuating a flush (2) of a toilet (3), at least comprising: - a housing (4) with a mounting space (5); - a pressure generator (10) which is arranged at least partially in the assembly space (5); and - at least one actuating button (14, 15) for actuating the pressure generator (10), wherein the at least one actuating button (14, 15) is connected to the pressure generator (10) via a ball joint (58). [2] Device (1) according to claim 1, wherein the ball joint (58) has a ball head (59). [3] Device (1) according to claim 2, wherein the ball head (59) is formed on the pressure generator (10). [4] Device (1) according to claim 2 or 3, wherein the ball head (59) is formed on a piston (23) of the pressure generator (10). [5] Device (1) according to one of the preceding claims, wherein the ball joint (58) has a joint socket (25). [6] Device (1) according to claim 5, wherein the joint socket (25) is formed on an actuating body (11) for the pressure generator (10). [7] Device (1) according to claim 6, wherein the joint socket (25) is formed in a pin (34, 35) of the actuating body (11). [8] Device (1) according to claim 7, wherein a key carrier (12, 13) for the at least one actuating key (14, 15) is arranged on the pin (34, 35). [9] Device (1) according to claim 7 or 8, wherein the pin (34, 35) is arranged in a receiving portion (45, 46) of the key carrier (12, 13).
