Definitions
- the invention relates to a device for the electromagnetic locking of a lock cylinder of a lock with at least one movable tumbler engaging in a recess on the circumference of the lock cylinder.
- electronic locking cylinders have already become known in which a movable tumbler is brought into a locked position by an electromagnetic drive or is moved out of such a locked position.
- An electromagnetic drive can be designed in a particularly simple manner as a stroke drive, but such a design has the disadvantage of a relatively high susceptibility to faults.
- the invention now aims to provide a device of the type mentioned at the outset, in which a secure locking can be achieved with an extremely small electromagnetic drive, which, in the event of vibration or other mechanical or electromagnetic influence on the locking cylinder, is not easily canceled again can be.
- the device according to the invention essentially consists in the fact that the movable tumbler interacts with an electromagnetic rotary drive and is secured in its closed position against emergence from the recess.
- an electromagnetic rotary drive is provided, similar in construction to a conventional, small-sized motor, and the fact that this rotary drive is used to prevent the movable tumbler from emerging from its locked position in a certain rotational position with low Actuators brings a high level of security.
- the actuating forces of the rotary drive only have to be sufficient to bring a support into active position against which the movable tumbler can no longer be moved out.
- the actuating forces required for the release are limited to turning the rotary drive in such a way that the movable tumbler can again emerge from a recess in which it is immersed in the closed position.
- the electromagnetic drive thus only effects the adjustment of the stop shoulder or support surface for the movable guard locking and it can therefore be found with an extremely small and simple rotary drive which exerts only small forces and nevertheless a high degree of security against mechanical Influences are brought about.
- the design is advantageously made such that the rotary drive releases the immersion of the movable tumbler from the recess of the locking cylinder in a defined rotational position.
- a particularly simple locking and secure support of the movable tumbler can be achieved in that the movable tumbler has protrusions or wings or the like protruding over its circumference and is pressed resiliently into the recess of the locking cylinder and in that the movable tumbler facing end face of the rotary drive in a defined rotational position of the rotary drive has recesses for receiving the projections or wings.
- Such a design permits the use of a particularly compact rotary drive, the design advantageously being such that the rotary drive has a coil wound as a stator in the z direction on the lateral surface of a cylinder and a magnetized magnet in the x direction , in particular tubular or sleeve-shaped rotor.
- the tubular or sleeve-shaped design of the rotor permits the arrangement of a spring for the resilient pressing of the movable tumbler and furthermore allows such a movable tumbler into the central cavity of such a rotor. can be pressed in if the projections or wings are not prevented from immersing into the rotor by a corresponding stop surface.
- the design is advantageously made such that the recess on the circumference of the locking cylinder has inclined surfaces over which the movable tumbler when the locking cylinder is rotated and the exchange movement is released, the rotary drive slides radially outward.
- Such a design leads to the fact that the movable tumbler is pushed outwards slidingly over the inclined surfaces, the movable tumbler being able to dip into the interior of the sleeve or tubular rotor and the wings or projections into corresponding recesses on the end face of the Can immerse the rotor.
- the design is advantageously made such that in addition at least one fixedly arranged, longitudinally magnetic part e.g. Ferrite is arranged, which brings the magnetized rotor into a defined rotational position when the coil is de-energized.
- the rotor can be automatically rotated into a defined starting position, in which in turn the stop surfaces for supporting the projections or wings of the movable tumbler are effective arrive and a further twisting of the locking cylinder is no longer possible, since the movable tumbler can no longer evade.
- the design is advantageously made such that the end face of the rotor has recesses in the form of slots for receiving the projections or wings of the movable tumbler, wherein such recesses can be designed, for example, in the manner of a screwdriver groove, which correspond in shape to corresponding wings of the bolt in order to allow the bolt to deflect when the rotor is in the corresponding rotational position.
- the tubular or sleeve-shaped design of the rotor allows a spring to be arranged coaxially to the rotor in the interior of the rotor, so that overall a particularly compact and simple construction is achieved, which is easily accomplished in one conventional lock with a conventional contour can be arranged.
- the locking is thus effected by a rotary drive which effects two or four connections.
- a rotation through 90 ° from the rest position is provided with regard to the specified field lines, and when the coil is no longer flowed through with current, the rotor will align itself according to a rigidly arranged magnetic part, for example ferrite .
- a bistable position can also be achieved, in which one of two possible end positions can optionally be assumed, in the end position either releasing or blocking the movement of the locking pin .
- the field of the ferrite need not be overcome for the rotational movement. However, a continuous flow is necessary here, since a stable rest position does not exist in the event of a power failure.
- FIG. 1 shows a schematic view of a lock with the electromagnetic lock according to the invention
- FIG. 2 shows a detail of FIG. 1 in the view corresponding to the direction of the arrow II
- FIG. 3 shows a representation analogous to that of FIG 90 ° rotated rotor
- FIG. 4 again showing a partial view corresponding to the arrow IV of FIG. 3, FIGS. 5, 6 and 7, variants of the configuration when using a ferrite for the independent assumption of a defined starting position with a currentless coil.
- the lock cylinder 2 has on its periphery a recess 3 for receiving a movable tumbler 4.
- the movable tumbler 4 dips into the recess 3 due to the force of the spring 5.
- the recess 3 has inclined surfaces 6 which cooperate with the movable tumbler 4. If the rotor 7 of the electric motor 8 is in the position shown in FIG. 1, the moving tumbler 4 is prevented from moving into the cavity 9 of the rotor 7, since the lateral projections or wings 10 of the movable tumbler 4 with the end face 11 of the rotor 7 collide.
- the coil of the electric motor 8 is indicated by 12, the coils being wound in the direction of the z-axis.
- the rotor 7 is magnetized in the direction of the x-axis, as a result of which the rotor is rotated in the direction of the arrow 13 when energized.
- FIGS. 1 and 2 also show a stationary ferrite 15, which causes the rotor 7 to rotate into a defined starting position when the coil 12 is de-energized.
- a position rotated by 90 ° can be seen, which position is assumed when the coil 12 has current flowing through it.
- the magnetization direction of the rotor corresponds to one of the arrows 18, depending on whether the coil 12 is currentless or not.
- a bistable locking is made possible, one of the two positions being adopted according to the arrows 18 when there is no current.
- the end points of the ferrites each lie above the poles of the coils, which are schematically indicated by a, b, c and d.
- the coil is only used to switch from one stable position to the other, as a result of which a particularly low current requirement is achieved, since a constant current supply is no longer necessary.
- a corresponding continuous current is required for the locking or unlocking.
