In the present invention, there is disclosed a device for mutual conditioned insertion and extraction of two groups of keys wherein the device consists of a base plate (1) with a first group (A) of locks (3) and a second group (B) of locks (3) attached thereto. The locks (3) are provided with an eccentric (31) projecting into a longitudinal groove (21) with a side recess (22) of a rear plate (2). The base plate (1) and the rear plate (2) are arranged with a possibility to displace relative to each other. The longitudinal grooves (21) with the side recesses (22) of the first group (A) of locks (3) and longitudinal grooves (21) with the side recesses (22) of the second group (B) of locks (3) are arranged parallel and opposite to each other. After insertion of keys into the locks (3) of the first group (A) and their subsequent angular displacement by 180 degrees, the eccentrics (31) angularly displace to the level of the longitudinal groove (21) profile and their keys cannot be removed from the locks (3). In this position, the eccentrics (31) of both the lock (3) groups (A and B) are situated in the longitudinal grooves (21) outside the side recesses (22). In this way, the transfer of the rear plate (2) relative to the base plate (1) by a pitch (a) is enabled. |
