Embodiment Construction

[0036] According to the invention, a piezoelectric element 13 is used, which serves as a pressure sensor converting a mechanical operation into an electrical signal. Embodiments of the invention in different forms are shown in the figures. According to the invention, a small, thin piezo element 13 is arranged in the region referred to as the operating zone 16 , wherein said piezo element 13 can be actuated by the user of the elevator installation by applying pressure. The piezoelectric element 13 is preferably arranged coaxially below the operating region 16 .

[0037] Piezoelectric elements 13 are particularly suitable because on the one hand, as pressure elements, they are in a position where an electrical signal is generated by a longitudinal force. On the other hand, the piezoelectric element 13 can generate a force or movement in the opposite longitudinal direction when it is operated by a corresponding response signal. The result is that, compared to other actuators, t...

Abstract

A control panel for an elevator has at least one pressure-sensitive action field in order to trigger an action by pressing. The control panel has a layered construction with a top plate, a base plate and a piezo element. An opening is provided in the top plate to define the action field. The piezo element is seated in the region of the opening between the top plate and the base plate so that by pressing in the region of the action field a force can be exerted on the piezo element and the piezo element delivers an electrical output signal to an electronic circuit. The electronic circuit provides an electrical acknowledgement signal in order to produce a change recognizable at the control panel as an acknowledgement.

Description

technical field [0001] The invention relates to a control panel for an elevator and to an elevator having a control panel. Background technique [0002] Control panels, also called indicator boards, are used especially in elevator installations. These control panels have to fulfill numerous, and some conflicting, requirements. On the one hand they should be operationally reliable and on the other hand they are expected to be economical. At present, aesthetics is also increasingly playing an important role. The control panels thus need to be visually pleasing and they must be acceptable by the design of the elevator. This is especially important for flat control panels. [0003] The control panel is perfectly designed so that it is essentially independent of the structure of the elevator car or shaft wall. [0004] Additionally, such control panels need to be hygienic and easy to clean. Additionally, security against vandalism in areas accessible to the public is of inc...
