Electrical control panel preferably for height adjustable tables
First Claim
1. An electrical operating panel which comprises:
- a mounting part and means for fixedly attaching the mounting part to a support structure;
a keyboard part having a front side and a rear side and at least one manually-operable operating key exposed on said front side for activating electrical switches, andhinge means for adjustably connecting said keyboard part to said mounting part at various angular positions, said hinge means including a rotary shaft connected to a first of said mounting part and said keyboard part and a bearing connected to a second of said mounting part and said keyboard part, said bearing providing a cylindrical inner wall for positioning around said rotary shaft to enable rotational movement between said shaft and said bearing, and retaining means for resisting rotational movement between said rotary shaft and said bearing with pressing of said at least one operating key.

Abstract
An electrical operating panel, in particular for height-adjustable tables equipped with actuators or lifting columns driven by an electric motor. The panel has a first part (1) intended for fixed mounting of the panel and a second part (2) with operating keys (19) for activating electrical switches. The two parts are hinged together, and the hinge is formed with a rotary shaft (10) on the no part and a bearing with a cylindrical face (13) on the other part and formed with interengaging projections (16) and depressions (15) such that the second part may assume various angular positions relative to the first part, the force between projections and depressions bearing greater than the necessary operative pressure on the operating keys, but smaller than the force necessary to manually move the second part between the various angular positions. The panel is of simple structure and easy to mount and use. The users may easily set the keyboard part in the desired angular position. Furthermore, the panel yields so that it is not damaged in case of collision with an object.
