Definitions

  • the invention relates to a locking device for a locking system.
  • Locking system is understood here to mean a system with mechanical elements which allows or blocks access to or access to an object, depending on whether or not there is authorization.
  • a locking device will in particular enable or prevent the operation of a lock cylinder or lock by rotation of a key or a door knob, by operating a door handle or similar means, or automated, by means of suitable drive means, etc.
  • Locking devices with mechanically and electronically - mechatronically controlled locking elements are known. They have all the properties of conventional purely mechanical locking devices. The additional electronically controlled locking also provides the option of individually activating and locking keys. With mechatronic locking devices so additional flexibility in the Schliessorganisation can be achieved.
  • the electronically controlled locking is based on a data transmission between a key-side electronic module and a lock-side electronic module.
  • This data transmission can be by touch - eg. By means of electrical contacts on key and lock - or non-contact - eg. By electromagnetic induction - take place.
  • Data can be transmitted in one or both directions.
  • a lock-side motor is activated, which electronically controls a locking element moves such that it releases the lock cylinder or the lock.
  • Such a locking device is known, for example, from International Publication WO 98/28508 or from International Publication WO 01/21913.
  • a disadvantage of such locking devices according to the prior art is that it is sufficient in tampering attempts to overcome the barrier caused by the locking element of the lock cylinder. This can be done by shock, by vibration, by brute force or otherwise.
  • the object of the invention is therefore to provide a mechatronic locking device which against external foreign influences, in particular against violent. Vibratory and / or shock or magnetic effects, is resistant and ensures safe functioning.
  • the locking device has a coupling element and an output element which can be brought into operative connection with locking means. It can be brought into a first and a second clutch state by means of electronically controlled drive means via drive means which move the clutch element.
  • the rotor - that is, the lock-rotatable member by key, door handle or similar means - is decoupled from the output member in the sense that there is no direct coupling via the coupling member or other coupling means which would cause rotation of the rotor causes a movement of the output element.
  • the coupling element couples the output element with a rotor which can be actuated by key, door handle, doorknob or a similar means or by an electric drive.
  • the approach according to the invention therefore differs from the prior art in that it is not simply necessary to decouple the rotor and the housing, but rather that The output element must be coupled to the rotor - and possibly also decoupled from the housing.
  • the coupling element or blocking element can be deflected from its rest position, for example by means of bumps.
  • this is exploited by being manipulated by a plurality of bumps until the locking element is in the free position.
  • the locking device is influenced so that the once located in the free-standing blocking element is fixed immediately in this - for example, by a constant acting on the rotor torque.
  • the mechanical decoupling of the rotor and output element in the first coupling state also has the advantage that even by violent rotation of the rotor, the lock can not be operated: The rotor rotates at most empty.
  • the output element in the first coupling state, is blocked with respect to a housing. Thus it is additionally locked against rotation.
  • the coupling element may have an at least partially spherical surface - and be formed for example as a ball. This minimizes the number of positions in which it engages - which is advantageous as described above. There is then the requirement that a shear lines between the elements to be coupled and the equator of the coupling element are aligned. When the equator of the coupling element is above or below the shear line, the coupling element is pushed away from the coupling layer by exerting force on one of the elements to be coupled.
  • the coupling element is neither coupled to the housing nor to the rotor.
  • the coupling element can then be rotated in its second coupling position during a rotational movement of the rotor. It is, for example, in an opening which is formed by recesses in the rotor and the output element.
  • Even if the coupling element is always mitFE with the output element, but it is a mechanically independent element. It can be provided that before the removal of the key, the rotor must be returned to its original orientation, so it can only be rotated by integer turns.
  • the drive means can, for example, the coupling element between two coupling layers - according to the two coupling states - move: In the first coupling position, the coupling element couples the housing and driven element, while it causes no coupling between the rotor and the driven element. In the second coupling position, it couples the rotor and the output element, but does not cause any coupling between the housing and the output element.
  • the coupling element serves as a blocking element propulsion means of the drive means obstruct the output member in the first coupling state relative to the housing.
  • the coupling element couples rotor and output sleeve.
  • blocking element and coupling element are designed and arranged so that the blocking element, when it is moved from the second to the first coupling state, at the same time by direct or indirect action, the coupling element moves away from the coupling position.
  • Another alternative provides that the output element is not blocked against the housing in the first coupling state.
  • the output element is, for example, firmly connected to an inner door handle.
  • this direct coupling between output element and inner door handle also provides some protection against manipulation - after all, the inner door handle must be moved with each manipulation attempt.
  • an electric motor can be used with a lifting spindle.
  • Electric motors are relatively economical power consumers compared to magnetic actuators. In addition, they are due to the design largely vibration, shock and magnetic resistant.
  • the coupling element can be displaceable by the drive means, quasi-positively guided ⁇ or even completely positively guided. This means that the position of the coupling element between the first and the second clutch layer is defined at all times by the drive means, for example by being connected to the drive means of the drive means.
  • this connection can be solved only by a certain amount of force; it may be, for example, that the propulsion means and / or the Kupplungselment has a permanent magnetic moment and thereby the coupling element adheres to the propulsion medium.
  • the connection is so strong that it is not solvable by normal bumps.
  • the coupling element is fixed by mechanical connections on the propulsion medium; The mechanical connections are, for example, solved as soon as the coupling agent is in the second coupling position.
  • the locking device can thus be designed so that the coupling element is always on one of two predetermined paths: on the first path quasi-positively guided or positively guided between the first and the second clutch position, and rotated on the second path through the rotor and relative to in a constant position about an axis of the rotor.
  • the drive means may be provided with spring means which are designed and arranged such that the coupling element located between the first coupling position and the second coupling position can be moved by mechanical action counter to a spring force in the direction of the first coupling position. This can prevent damage caused by violent manipulation attempts and failure of the drive.
  • the coupling element When the coupling element is in an undefined position between the first and second coupling layers, and force is applied to a shear line, the coupling element deviates toward the first coupling layer without causing any damage.
  • Locking device may - in the event that it is used with a lock cylinder - have a key blocking element which is movable by inserting the key in the key opening from a first position to a second position, wherein it in the second position, a withdrawal of the key only at certain, predetermined orientations of the rotor allowed.
  • this allows the user to open a door in a manner known per se by pulling on the key which is not oriented vertically.
  • it can be ensured that the system is always in a defined position with the key removed, in which the coupling element between the two coupling layers is displaceable.
  • the key blocking element blocks the rotor in the first position against rotation so that it can not be moved away from its defined position by a screwdriver or similar means or by randomly induced movements.
  • the Belleblockerelement is damaged at best, because of the mechanical decoupling of rotor and housing but never the essential elements for operating the bolt elements.
  • the key blocking element may be, for example, a rocker arm which is connected to a spring which causes a restoring force to the first position.
  • the additional security which is caused by the above elements, has the consequence that the locking device, for example, manages without purely mechanically actuated tumblers.
  • This can be a locking device according to the invention with any existing locking systems combined and used across plants.
  • the locking device allows a connection of multiple systems and a deployment in multiple systems with a system-neutral key.
  • a locking device according to the invention may, however, additionally also have mechanical tumblers.
  • the inventive locking device is thus system neutral in this embodiment: mechanical and mechantronic system components are completely separable.
  • FIG. Very schematically are a rotatable by a key rotor 2 and connected to a. For example, directly into a door housing connected and therefore not rotatable stator 3. Between the rotor 2 and stator 3 is designed as a drive output shaft output element 4. This is at least partially the axis of rotation of the rotor is rotatable and can be brought into operative connection with a driver, which is designed for actuating locking elements, so that the bolt - if necessary, if certain conditions are met - by turning of the output element 4 can be actuated.
  • a driver which is designed for actuating locking elements
  • Both the rotor and the stator each have a recess 2.1, 3.1, which are aligned in the drawn arrangement with a recess 4.1 in the output element.
  • a coupling element 5 is located in the opening formed by these recesses.
  • the coupling element 5 ball is formed. But it could also have a different shape and be, for example, a pin with a partially spherical surface or a pin.
  • the operating principle is the following:
  • the coupling element is displaceable by means not shown drive means of the opening. It assumes a first coupling position - or blocking position - when it is on the shear line S1, which is formed between the stator 3 and the output element. This state corresponds to the first coupling state.
  • the Kupplugselement couples the output element with the stator. It prevents rotation of the output element and thus actuation of the bolt. But the coupling element does not cause a coupling between the rotor and the driven element when it is in the first coupling position. Rotor and output element and thus also rotor and bolt are thus decoupled when the coupling element is in the locked position. This is a difference from the prior art, where blocking is effected by locking the rotor to the stator.
  • the arrangement shown in the figure is an example of a locking device with a coupling element 5, which is electronically controlled between a first and a second coupling position - according to the first and second coupling state -verschiebbar, wherein the coupling element 5, 5 ⁇ in a first coupling position the Output element 4 with respect to the housing blocks and in a second clutch position the output member 4 couples with the rotor 2, wherein the rotor 2 is not coupled to the output member 4 when the clutch member is in its first clutch position.
  • Figure 2 shows a variant of the principle shown in Figure 1, where the coupling element 5 'is not spherical, but has a partially spherical surface.
  • the recess 2.1 in the rotor is in this embodiment, for example. Limited so that the coupling element the rotor 2 and the output element 4 only couples when it is inserted into the opening to the stop. If the coupling element withdrawn slightly, it is pushed back at a torque on the rotor due to its partially spherical surface in the direction of its first coupling position.
  • the hemispherical surface portion of Figure 2 may also be provided another surface shape which causes such a recoil - for example, a conical shape, etc.
  • the actually to be met in this embodiment condition is that the shape of the coupling element is such that it has an area in which it is constantly rejuvenated.
  • the depth of the recess 2.1 is limited in the rotor so that the coupling element in its second coupling position is also at a stop or almost at a stop, also be present in a spherical coupling element.
  • FIG. 3 very schematically illustrates the set of all states 11.
  • the coupling element is guided through the recesses and is displaceable in only one direction x; the states can therefore be characterized by the position in this direction x.
  • the upper diagram of the figure shows the situation for the arrangement according to FIG. 1.
  • the subset of those states in which the coupling element is in its second coupling position and enables the opening of the lock is provided with the reference numeral 12 in the FIGURE. Due to the spherical surface of the coupling element its position must be chosen very precisely so that its equator is on the shear line S2. Otherwise, the coupling element is pushed away in one or the other direction with a torque acting on the rotor. This fact has the effect that the subset 12 of the states in which release takes place is very small. With random movements, the probability almost disappears that the coupling element in the release position (the second clutch position) gets.
  • the lower diagram of Figure 3 relates to the structure according to Figure 2. This differs from that of Figure 1, characterized in that the Kupplungselelement is also in its second coupling position on a stop.
  • the subset 12 of the states in which a release takes place is therefore entered completely at the edge. Also in this case, it is small in comparison to the amount of all states, since the coupling element is also pushed away from the coupling position with a torque on the rotor, if it is not positioned exactly in the Kupplunslage.
  • the cylinder lock partially shown in Figures 4 and 5 has a double lock cylinder 1 with a first, provided for a door outside part cylinder 1.1 and a second, provided for a door inside partial cylinder 1.2 (optional).
  • the second partial cylinder 1.2 is shown only schematically in the figure.

  • the rotor is provided with a key opening 2.2.
  • the driver 21 can be coupled in a manner yet darloom via a to be inserted by inserting a key 30 wing member 22 via the output member 4;
  • An analogous device can also be provided for the possibly existing second partial cylinder 1.2.
  • the wing element 22 is mechanically coupled to an output element 4. This can be coupled in the manner already explained either with housing parts or the stator 3 or with the rotor.
  • the serving for this purpose coupling element 5 is spherical in the example shown.
  • the coupling element is displaceable by drive means 23 between the first coupling layer (FIG. 4) and the second coupling layer (FIG. 5). In the first coupling position, the equator of the coupling element is located on the shearing line between the output element and the stator, in the second coupling position on the shearing line between the output element and the rotor.
  • the drive means are electronically controlled.
  • the cylinder lock has a not-shown electronic module and communication means for communication with a data carrier of the key 30.
  • the communication means for the communication between the data carrier and electronic module can be formed in a conventional manner for non-contact communication via electromagnetic radiation, or the key can Also have contacts that are contactable via pins of the cylinder lock. Other communication options are conceivable.
  • the electronic module determines - for example, also in a conventional manner - by means of data exchanged with the data medium of the key, whether the key authorizes access to the locked object. With an authorization, the electronic module controls the drive means so that they bring the coupling element in the second coupling position and release the lock ( Figure 5).
  • the key holder can then cause a rotation of the output element 4 with a rotation of the key, with the coupling element in the opening, which form through recesses 2.1, 4.1 of the rotor and the output element rotates.

  • movable key blocking element 24 is shown. This is mounted in the figure by a pivot pin 25 on the rotor 2 and is held with spring means 26 in its first position when no further forces act. In the first position, it blocks the rotor 2 by standing against the stator 3 in a standard orientation against rotations. By inserting a key, it can be brought into its second position against the spring force. As a result, the blocking of the rotor is released, and this can be freely rotated.
