Lock-box

Lock box for an electro-mechanical lock with

• a housing (1)
• comprising a first follower half (2) that has a form-closed connection with a first handle for actuating the lock, with the first follower half (2) having an actuating element for an unlocking linkage (20),
• a second follower half (5) which is connected in a form-closed way with a second handle for the operation of the lock,
• restoring elements (9, 10) to bring the follower halves (2, 5) in rest position after actuation has been effected,
• a coupling element (6) which in its rest position (a) allows the first (2) and second follower half (5) to be freely movable relative to each other and in its working or operating position (b) causes the two follower halves (2, 5) to be connected with one another,
• a motor (7) which when activated brings the coupling element (6) in operating position (b),
• a control device (8) acting on the motor (7) after relevant control signals are received as well as
• an energy supply,
• characterized in that the coupling element (6) is provided with a pivotable articulated arm (11) supported on the housing (1), said arm when in actuating position (b) engaging with recesses (12, 13) arranged in both follower halves (2, 5) so that when the second handle is actuated the lock can be opened via the second follower half (5).
