Abstract
The disclosure is concerned with an electrically operable central locking and unlocking device for vehicle doors with mechanical locks at each door or lid, and with electromechanical actuation for such door locks in which the actuation is transferred by a vertically movable actuating rod capable of moving between an unlocked position and a locked position, to a control rod of the associated door lock. The device includes a reversible electric motor, a transmission, and an actuating mechanism for the actuating rod. The device also includes exterior ridges on a spindle-nut and projecting formations which serve to carry along the actuating rod during the lock stroke and during the unlocking stroke. The ridges can override, after completion of the lock stroke, as well as after completion of the unlock stroke, the projecting formations. The device includes a spindle which is positioned parallel to the up-and-down movement of the actuating rod, and which is provided with a self-retarding thread and on which is guided the spindle-nut which on each side is formed with the projecting ridges. The actuating rod is formed of two fork-like arms which extend on both sides of the spindle, and each arm is formed with a resiliently deflectable projecting formation.
