Locking device

Locking device for independently operating a bolt by a mechanical activation and a non-mechanical activation, comprising

• a bolt (20) movable between an extended position in a locked state and a retracted position in an unlocked state,
• a first follower (61) for operating the bolt (20), the first follower (61) being pivotable on a first pivot (P1) and comprising a follower arm (68) configured to engage the bolt (20) and move it between the extended position and the retracted position,
• a second follower (63) for operating the first follower (61) and thereby also the bolt (20), the second follower (63) being configured to contact the first follower (61) and move the follower arm (68),
• an activation element (30) for mechanical activation of the bolt (20), said activation element (30) being rotatable and configured to operate the second follower (63), and
• a control assembly (80) for non-mechanical activation of the bolt (20),
• the control assembly (80) comprising an actuator (40), a cam (41) operated by the actuator (40) and a coupler (50) for coupling a movement of the cam (41) to the second follower (63) and thereby operate the second follower (63), wherein
• the control assembly (80) comprises a play (P) such that the second follower (63) when operated by the activation element (30) is configured to move freely in relation to the cam (41),
• the first pivot (P1) is the activation element (30) such that the first follower (61) is configured to rotate about the activation element (30), and
• the coupler (50) comprises a toothed wheel (51) rotatable on a second pivot (P2) and the second follower (63) comprises a rack that is arranged in constant mesh with the toothed wheel (51).

• the coupler (50) comprises
• a toothed section on the activation element (30), and
• a fourth follower (55) comprising a rack and being arranged in constant mesh with the toothed section on the activation element (30),
• the fourth follower (55) is connected to the cam (41) in a first connection (C1) by one of them comprising a protrusion (42) and the other comprising an opening (53) into which the protrusion (42) extends when the fourth follower (55) and the cam (41) are arranged together,
• the protrusion (42) and opening (53) are arranged in such a way that a linear movement of the cam (41) causes the protrusion (42) to contact a wall of the opening (53) and thereby causes a linear movement of the fourth follower (55), and
• the opening (53) forms the play (P) such that the fourth follower (55) can move linearly driven by a mechanical activation of the activation element (30) without causing the cam (41) to move also.
