Abstract
The invention relates to an improved locking device for the closure of doors on cabinets, of boxes or compartments, which offers high resistance to unauthorized attack and, in particular, can take up high torques. For this purpose, use is made of a coupling arrangement having a manually or electronically movable actuating member, a driver (40), which interacts with the actuating member, and a blocking member (50). The blocking member (50) has the form of a cylinder, the cylinder axis of which runs parallel to the rotor axis (19). The blocking member (50) in its blocking position engages in a depression (17) on the outer side of the rotor (10) or in a depression (22) on the inner side of the wall (21) of the stator (20) and is held in this blocking position by spring force.
Claims19
A locking device for closing doors on cabinets, boxes or compartments,
- with a stator (20) for attachment to the door, wherein the stator (20) forms a pot-shaped housing shell, namely a floor which can be placed on the door and a wall (21) surrounding the floor,
- having a rotor (10) which is rotatably mounted on the stator (20) and can be connected at the door-side end to a locking element (70) in order to move the latter from a locking position into an unlocking position by movement of the rotor,
- having a blocking member (50) which can be moved between a blocking position and a release position, wherein the movement of the rotor (10) is possible only in the release position of the locking member (50),
- wherein a coupling arrangement (30, 40, 50) is provided which prevents unauthorized rotation of the rotor (10),
- the coupling arrangement (30, 40, 50) comprising a manually or electronically movable actuator (30), a driver (40) cooperating with the actuator (30) and with a locking member (50),
- wherein the blocking member (50) in its blocking position dips into a trough (17) on the outside of the rotor (10) or in a trough (22) on the inside of the wall (21) of the stator (20) and is held in this blocking position by spring force,
- wherein to release the movement of the rotor (10), the actuator (30) can be coupled to the driver (40), and the blocking member (50) can be displaced from the trough (17, 22) into a release position counter to the spring force,
- wherein the blocking member (50) has the shape of a cylinder and the cylinder axis runs parallel to the rotor axis (19);
- characterized in that the actuator (30) is mounted movably on the rotor (10) and can be coupled to the driver (40) in order to release the movement of the rotor (10), wherein the driver (40) is movable with the rotor (10) in the coupled position and the blocking member (50) can be displaced from the stator-side trough (22) into the rotor-side trough (17) by a rotational movement of the rotor (10);
- characterized in that the actuator (30) is mounted on the rotor (10) so as to be displaceable in the radial direction, wherein the actuator (30) is mounted movably in a guide recess (14) of the rotor (10), and preferably for better guidance of the actuator (30) from the upper side (11) of the bottom surface of the rotor (10) are provided guide webs (13).
