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.

A plug-in and disconnect aid device for plug-in subassemblies of a mechanical arrangement, which can be slid into a rack subassembly, with a lever connecting to a plug-in subassembly by means of an end piece having an axis of rotation of the lever positioned vertically to the insertion plane in the end piece wherein the lever is designed to release a locking element, characterized by: the lever being designed as a connecting member which by means of a guide piece is positioned in a guide of a first fixed-mounted arm of said end piece; a second arm, parallel to the first arm and having a guide edge, is designed with a locking projection spring-mounted in such a fashion that its guide edge mates with the guide piece; said guide being designed so that a swivel action of the lever produces a motion of the second arm parallel to the insertion plane; and a first plurality of projections on said lever for cooperating with a transverse rail having a keyway cut therein meshing in a locked position of the lever with a transverse rail projection corresponding to the keyway; whereby a swivel action of the lever towards the transverse rail causes one of the first plurality of projections of the lever to support itself on an outer surface of the cooperating transverse rail projections, and a swivel action of the lever in the direction of a frontal panel of the subassembly, causes an inner projection of the keyway of the lever to support itself on an inner surface of the cooperating projection of the transverse rail.
