Definitions
- the invention relates to a locking device for locking doors on cupboards, boxes or compartments.
- a locking element of the locking device interacts with corresponding locking plates on the cabinet, on the box or on the compartment to be locked.
- the locking element can be a bolt or a push rod.
- a locking device In order to prevent unauthorized opening of the door, it is also known to equip a locking device with a mechanical lock, such as a lock cylinder or an electronic lock, and to grant access or access only to authorized persons.
- Such locking devices have a high level of security. Unauthorized persons therefore try to open the locking device by rotating or moving the locking element. In the event of such an unauthorized attack from the outside, the locking device must be able to offer considerable resistance.
- the object of the invention is therefore to provide an improved locking device which offers high resistance to an unauthorized attack on the locking device, in particular can absorb high torques.
- the new locking device for locking doors on cabinets, boxes or compartments comprises a housing for attachment to the door, the housing forming the stator of the locking device and in the shape of a pot is formed, namely has a bottom which can be placed on the door and which is attached to the door leaf.
- a locking element cooperates on the other side of the door in a known manner with a strike plate on the cabinet, box or the compartment to be locked.
- the rotor is connected directly or indirectly to the movable locking element. By moving the rotor in both directions of rotation, the locking element is moved from the locking position into the unlocking position or back into the locking position.
- the rotor is rotatably mounted on the housing for this purpose.
- the new locking device comprises a coupling arrangement, with a locking mechanism preventing unauthorized rotation of the rotor and thus also rotation of the locking element.
- the coupling arrangement comprises a manually or electronically adjustable actuator, a movable driver and a locking member.
- the locking member which can be displaced between a locking position and a release position, enables the rotor to move only in its release position.
- the actuator has two positions, a decoupled rest position where the rotary movement of the rotor is prevented by the locking member and a coupled position where movement of the rotor is possible.
- the locking member has the shape of a cylinder, the cylinder axis running parallel to the rotor axis. In its locked position, the locking member dips into a trough on the inside of the wall of the stator or on the outside of the rotor. The size of this crescent-shaped depression is adapted to the cylinder radius of the locking member. In the locking position, the locking member is pressed into this trough by a spring force, preferably less than a third of the locking member is located in this trough.
- the spring force is exerted here by a spring which exerts a spring force radially to the rotor axis.
- the spring for a locking member is held on the rotor when the trough is provided on the stator.
- the spring is held on the stator when the trough is provided on the rotor.
- the authorized user can move the actuator from the decoupled rest position into a coupled position, where this actuator is coupled to the driver.
- the actuator is mounted on the rotor and when the rotor rotates, the driver is then moved along by its coupling with the actuator.
- the driver moves the locking member from its locking position into a release position.
- the locking member is displaced by the driver against the acting spring force out of the trough on the stator side and is received on the rotor.
- the driver has, on its lower part arranged below the rotor, a channel running in the radial direction, which in the locking position of the locking part is filled by the locking part.
- the parallel side surfaces of the channel act in a special way as stop surfaces on the locking member. They drive the locking member out of the stator-side trough because they attack the apex of the cylindrical locking member.
- the stop surfaces can also be beveled in order to reduce the disengagement torque.
- the actuator is mounted on the stator or housing of the locking device and engages in a groove driver, whereby the driver is held and when the rotor is rotated, the locking element is moved from its locking position to a release position.
- the locking member is displaced against the acting spring force from the trough on the rotor side into a trough on the stator side and is received there.
- the driver has a channel which runs in the radial direction and which is filled by the blocking part in the blocking position.
- the parallel side surfaces of the channel act in a special way as stop surfaces on the locking member. They drive the locking member Movement of the rotor out of the trough on the rotor side, as they attack the apex of the cylindrical locking member.
- FIG. 1 shows a perspective view of a locking device without a rotor cover
- FIG. 2 shows a view of the underside of a first locked locking device without a bottom surface of the stator
- FIG. 3 shows a perspective view of the underside of a further locked locking device without a bottom surface of the stator
- FIG. 4 shows a view of the underside of the locking device without the bottom surface of the stator from FIG. 3,
- FIG. 5 is a view of FIG. 4 in the release position
- 6 shows a perspective view of the coupling arrangement, decoupled
- Fig. 12 is a view of Fig. 11 after an unauthorized rotor rotation attempt
- FIG. 13 shows a view of FIG. 11 in the unlocked position.
- the new locking device comprises a stator 20 for attachment to the door, the stator 20 being pot-shaped, namely having a base which can be placed on the door and which is fastened to the door by means of fastening elements 24 - shown in FIG. 2.
- a locking element 70 on the other side of the door cooperates in a known manner with a strike plate on the cabinet, box or the compartment to be locked.
- a central hole in the bottom of the stator 20 is located after the assembly in front of the corresponding hole in the door for the passage of the rotor end or a drive wheel connected to the rotor.
- the rotor 10 or the drive wheel connected to the rotor 10 is connected directly or indirectly to a locking element 70.
- a bolt is non-rotatably attached to the rotor end.
- the rotor 10 is connected to a drive wheel, which with a corresponding gear or Toothed linkage interacts to act on a corresponding locking element.
- the rotor 10 is rotatably mounted on the stator 20 for this purpose. As a result of the movement of the rotor 10, the locking element 70 is moved out of the locking position into the unlocking position or back into the locking position.
- rotor 10 and stator 20 form a common outer surface.
- This locking device can for example comprise an electronic actuating device or be accommodated together with mechanical or electronic actuating elements in a housing.
- the pot-like stator 20 shown in FIG. 1 is surrounded by a wall 21.
- This wall 21 delimits an interior space.
- a look into the interior is shown in FIG. 2, where the bottom surface of the stator 20 has been omitted for the sake of clarity.
- the underside 12 of the rotor 10 is visible.
- This rotor 10 is mounted rotatably about an axis of rotation 19.
- stops 23 are attached to the bottom surface of the stator 20 or are part of the stator 20.
- Another embodiment of the locking device shows a stator 20 without stops, see FIG. which are pressed into recesses 22, 22 'by a spring force acting radially outward.
- troughs 22, 22 are located in the wall 21 of the stator 20.
- Fig. 2 and Fig. 3 the blocking position of the blocking members 50, 50‘ is shown.
- the locking members 50, 50 are held in this locking position by the force of the springs 60, 60‘.
- the springs 60, 60 are stored in a spring receptacle 16, 16‘ on the rotor 10.
- the spring receptacle 16, 16 ' is open at the radially outer end, so that the front end of the spring 60, 60' rests directly on the locking member 50, 50 '.
- the spring receptacles 16, 16 ′ are provided in a transverse bar 15 which is located on the underside 12 of the rotor 10.
- a continuous crossbeam 15 is provided with its one The end for receiving the locking member 50 'extends to the wall 21 of the stator 20.
- the cross bar 15 ends in front of the movement path of the driver 40, which can be moved along the wall 21.
- the locking members 50, 50 ‘only partially immerse into the troughs 22, 22‘ on the stator 20.
- the greater part of the locking members 50, 50 ‘ is located outside of the troughs 22, 22‘.
- the greater part is received in a rotor-side trough 17, which is an extension of the spring receptacle 16‘.
- the locking member 50 also dips into such an extension of the spring receptacle 16 on the rotor 10.
- the middle area of the locking member 50 is located in a channel 44 of the driver 40.
- the cylinder axis runs parallel to the axis of rotation 19 of the rotor 10.
- the locking member 50 together with the driver 40 and the actuator 30, is an element of a coupling arrangement.
- the second locking member 50 ' is not an element of the coupling device and not a necessary part of the locking device.
- the diametrically opposite arrangement of a second locking member 50 ‘improves the realignment of the locking member 50 after the rotation of the rotor 10 has ended.
- Fig. 6 shows the elements of the coupling arrangement, namely locking member 50, driver 40 and actuator 30 in a decoupled position. In this decoupled position, rotation of the rotor 10 is not possible. If, for example, an unauthorized person tries to rotate the locking element 70 in order to cause the locking device to open, this torque is transmitted to the rotor 10, which moves slightly in the direction of the rotational engagement, for example shown in FIG. 4. For this, a movement play of the rotor 10 is provided. As FIG. 2 shows, in contrast to the locking member 50 ', which is received in the extension 17' without play, the locking member 50 in the extension 17 is not touched by the side surfaces of this extension 17, but held in position solely by the force of the spring.
- the side surfaces of the extension 17 are formed into stop bevels 171 and 172 at the mouth exit of the extension 17.
- the orientation of these stop bevels 171, 172 is selected such that, in the event of an unauthorized rotational action on the locking element, the stop bevels 171 and 172 press the locking member 50 into the stator-side trough 22.
- the stop bevel 171 generates an additional force on the locking member 50 in the direction of the trough 22.
- the rotor 10 is rotated slightly, namely until the stop bevel 171 rests on the locking member 50.
- a further external action leads to the incline 171 pressing the locking member 50 in addition to the force of the spring 60 into the trough 22 due to the acting torque. If a rotary attack is attempted in the opposite direction, the run-on bevel 172 has the same effect that the locking position of the locking member 50 is retained.
- an actuator 30 is actuated manually or electronically and moved from its decoupled rest position - shown in FIG. 6 - into a coupled position - shown in FIG. 7.
- the actuator 30 is mounted on the rotor 10, namely displaceably in a guide recess 14 on the upper side 11 of the rotor base.
- the driver-side end face 31 of the actuator 30 is located for its reliable guidance between two guide webs 13 which protrude upward from the bottom surface of the rotor 10 on its upper side 11.
- a pivotable actuator is also possible as part of the coupling arrangement.
- the decoupled position is shown in FIGS. 1, 2, 3, 6 and 8.
- the actuator 30 is located with its driver-side end 31 between the stops 13 in front of the driver 40.
- the driver 40 has opposite this driver-side end 31 a groove 47 in its upper part 41.
- This upper part 41 of the driver 40 extends through one Edge-side, radially extending slot 18 in the bottom surface of the rotor 10.
- This edge-side slot 18 can be seen in FIG. 8 and is located above the movement path of the driver 40.
- the longitudinal extension of the slot 18 is preferably longer than the upper part 41 of the driver 40 , this makes assembly easier.
- the driver 40 has a radial alignment that is adapted to the radius of the wall 21 of the stator 20.
- the driver-side end face 31 of the actuator 31 is inserted into the groove 47 of the driver 40, see FIGS. 7 and 10.
- the actuator 30, in this case with its feet 32, is guided in the guide recess 14 on the rotor. 7 clearly shows that the actuator 30 engages in the groove 47 of the driver 40.
- the driver 40 is now also moved. With such a movement of the rotor 10, for example counterclockwise, which shows on the rear side of the rotor 12 as a clockwise movement, the stop surface 45 of the moving driver 40 strikes against the locking member 50, see Fig. 5.
- FIG. 5 shows the situation after the locking member 50 has been displaced from the trough 22 on the stator side. If no rotation limiters are provided for the rotor 10, it can be moved until the locking members 50, 50 'engage again in a stator-side trough 22, 22', in FIG. 5 after a rotation of 180 degrees. Further troughs 22, 22 ′′ on the stator side can also be provided, which temporarily interrupt a rotor movement.
- FIGS. 11 to 13 a reverse arrangement has been chosen.
- the locking members 50, 50 ‘are stored in their locking division in troughs 17, 17 on the rotor side and are pushed into troughs 22, 22‘ on the stator side when the rotor 10 is released and rotated.
- the release position of the locking members 50, 50 can be seen in FIG.
- the locking members 50, 50 ‘are pressed into the crescent-shaped troughs 17, 17‘ of the rotor 10 by the radially acting force of the spring 61, which is mounted on the stator 20.
- the locking members 50, 50 ‘are added to about a third.
- the middle region of the locking member 50 is located in a channel 44 of the driver 40.
- the locking member 50, together with the driver 40 and the actuator 30, is an element of a coupling arrangement.
- the second locking member 50 ' is not an element of the coupling device and is not a necessary part of the locking device.
- the diametrically opposite arrangement of a second locking member 50 ‘improves the realignment of the locking member 50 after the rotation of the rotor 10 has ended.
- Fig. 11 shows the elements of the coupling arrangement, namely the locking member 50, the driver 40 and the actuator 30 in the decoupled position.
- rotation of the rotor 10 is not possible.
- the locking member 50 is moved together with the driver 40 and strikes when turned clockwise against a stop bevel 271 or when rotated in the opposite direction against a stop bevel 272 at the exit of the stator-side trough 22.
- the alignment of these stop bevels 271, 272 is chosen so that a force is generated which, in addition to the spring force of the spring 61, presses the locking member 50 into the trough 17 on the rotor side.
- an actuator 30 is manually or electronically inserted into the groove 47 on the driver 40 and moved from its decoupled rest position - shown in FIG. 11 - into a coupled position - shown in FIG. 13.
- the actuator 30 is driven by a motor unit which is located outside the stator 20, which is not shown.
- the actuator 30 moves from the outside in a straight line into the stator 20 and inside the stator into the driver 40 and holds it in position.
- a pivotable actuator is also possible as part of the coupling arrangement. By rotating the rotor 10, the locking member 50 is moved along with it.
- the locking member 50 strikes against the stop surface 45 or 46 of the driver 40 held in position the locking member 50 presses against the force of the spring 60 from the rotor-side trough 17 in the direction of the trough 22 on the stator 20. Thereafter, the rotation of the rotor 12 to unlock the locking element is possible. 13 shows the situation after the locking member 50 has been displaced into the trough 22 on the stator side. If no rotation limiter is provided for the rotor 10, it can be moved as far as until the locking members 50, 50 'engage again in a stator-side trough 22, 22', in FIG. 13 after a rotation of 180 degrees. Further troughs 22, 22 ′′ on the stator side can also be provided, which temporarily interrupt a rotor movement.
- This new locking device is the coupling arrangement comprising the actuator, the driver and the locking member, which, when properly actuated, allow the rotor 10 to rotate after the locking member 50 is moved from its locking position to a release position at the beginning of the rotary movement of the rotor 10.
- the locking device offers a high level of security against theft, since unauthorized attacks on the locking element do not lead to unlocking, since high torques can be absorbed by this new locking device. A high security standard is achieved with this locking device.
