Abstract
The invention concerns a plug-in and disconnect aid device for plug-in subassemblies of a mechanical arrangement which can be inserted in rack subassemblies, wherein a lever by means of an end piece is connected to a subassembly in such a fashion that the axis of rotation of lever is positioned vertically to the insertion plane in the end piece and wherein the lever is designed to release a lock element. In accordance with the invention, the lever is designed as a connecting member which by means of a guide is positioned in a guide of a first fixed-mounted arm of end piece; that parallel to the first arm; there is a second arm having a locking projection spring-mounted in such a fashion that its guide edge mates with guide piece; that the guide is designed such that a swivel action of lever is converted into a motion of the second arm parallel to the insertion plane; and that lever is designed with a keyway whose outer edges are designed as projections. Thereby the design produces a plug-in and disconnect aid device whose spatial requirement is only negligibly larger than that of the keyway of the cooperating transverse rail of the rack subassembly.
