A device for cleaning a handle, includes a handle including a gripping surface to be disinfected, an application member for applying a cleaning liquid to the gripping surface, and cleaning liquid supply including at least one reservoir for receiving cleaning liquid and distributing it to the application member. The application member includes at least one buffer reserve arranged in contact with the gripping surface. The device includes a unit for actuating the application member, including a driver configured to move the buffer reserve and/or the gripping surface relatively with respect to one another so as to apply cleaning liquid to substantially the entire gripping surface during this movement.

A device for cleaning a handle, including a handle including a gripping surface to be disinfected, an application member for applying a cleaning liquid to the gripping surface, and cleaning liquid supply element including at least one reservoir for receiving cleaning liquid and distributing it to the application member. The application member includes at least one buffer reserve arranged in contact with the gripping surface. The device includes a unit for actuating the application member, including drive element configured to move the buffer reserve and/or the gripping surface relatively with respect to one another so as to apply cleaning liquid to substantially the entire gripping surface during this movement.

Described is a spring mechanism. The spring mechanism includes a leaf spring housing with leaf springs radially disposed within the leaf spring housing. The leaf springs being flexible between a rest state and tension state. A winding mechanism is engaged with the leaf springs for causing the leaf springs to flex from the rest state to the tension state. The winding mechanism includes a pushing pin wheel with a plurality of pushing pins protruding therefrom that rest against the leaf springs. The pushing pin wheel is rotatable such that rotation of the pushing pin wheel causes the leaf springs to flex from the rest state to a tension state. Release of the tension (i.e., when the leaf springs return to the rest state from the tension state) causes rotation of the leaf spring housing, which causes rotation of a corresponding release gear set and output drive.

Nonlinear spring. In one embodiment, the spring includes two opposed curved surfaces curving away from one another. A flexible cantilever member is disposed between the two opposed curved surfaces and a mass is attached to a free end of the cantilever member wherein the flexible cantilever member wraps around one of the curved surfaces as the cantilever member deflects to form a nonlinear spring. Energy harvesting devices and a load cell are also disclosed.
