AI Technical Summary
Existing toilet flush actuation devices lack design flexibility due to limitations in the type of movement allowed by actuating buttons, restricting the variety of design options and requiring multiple parts for different actuation types.
A device with a convex pressure surface on the actuating button that allows both translational and pivoting movements, enabling a single design to accommodate various actuation types, and includes a housing with interchangeable actuating devices for enhanced flexibility.
The solution provides a high degree of design freedom and versatility, allowing for multiple actuation options while maintaining a unified design, thus reducing the need for multiple parts and enhancing aesthetic customization.
Abstract
Description
[0001] Device for flushing a toilet
[0002] The present invention relates to a device for flushing a toilet. Such toilets are used, in particular, for collecting bodily excretions.
[0003] Toilets typically have a toilet bowl that can be cleaned by flushing after use. The flush may, for example, have a cistern for holding a flushing fluid, with the flow of the flushing fluid from the cistern into the toilet bowl being controllable via a drain valve. The drain valve can be actuated by a toilet user via at least one actuating button on the device.
[0004] The device is typically located in a wall inspection shaft and covered with a (particularly decorative) cover plate comprising the at least one actuating button. By means of the at least one actuating button, a bellows, for example, can be pressed via an actuating mechanism. This generates compressed air, which can be used to control the drain valve. The at least one actuating button can be moved translationally or pivotably within the device or the cover plate. The actuating mechanism must be adapted to the type of movement or guidance of the at least one actuating button, so that the device can have actuating buttons that can be moved either only translationally or only pivotally. This limits the design freedom of the device.
[0005] The object of the invention is therefore to at least partially solve the problems described with reference to the prior art and, in particular, to provide a device for actuating a toilet flush that allows a high degree of design freedom. Furthermore, the device can have many identical parts and / or serve as a universal platform for various design variants. This object is achieved with a device according to the features of the independent patent claim. Further advantageous embodiments of the invention are specified in the dependent patent claims.
