  • Patent number: 9653227
    Abstract: A switch for controlling a control circuit or an operating current of electric-motors in linear gear drives includes: a switch casing, having at least an upper part including keys, and a lower part for forming a receiving space; a circuit board incorporated in the receiving space with microswitches including a switch casing and a spring-biased push-rod therein; wherein, when the keys are actuated by a user, the push rod actuates the micro-switch to control a control circuit or operating current, and wherein the switch contains at least one locking element, transferable between a locking position, which locks the keys, and a release position, which releases the keys. To prevent damage to a switch from pressure forces during actuation, the locking device is formed such that the pressure applied to the key is transferred onto the switch casing and/or the circuit board plate over as wide an area as possible.

  • Publication number: 20150354679
    Abstract: An electromotive linear drive in the form of a dual drive adjust movably mounted parts of reclining and seating furniture. Two threaded spindles (2, 3) driven by a worm gear and which are arranged one behind the other and flush with one another for displacing a lifting element. Bearings are provided at both ends of each threaded spindle (2, 3). The bearings are designed as roller bearings (4, 5) having an inner ring (6) and an outer ring (7). The aim of the invention is to design an electromotive dual drive in such a way that a short overall length is achieved and that the stability of the structure is increased. Said aim is achieved by arranging an abutment between both roller bearings (4, 5), which accommodate the spindle ends, on which the roller bearings are supported on from both sides.
