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 enables or blocks access to an object, depending on whether there is authorization or not.
• a locking device is in particular the actuation of a locking cylinder or lock by turning a key or a door knob, by operating a door handle or comparable means, or automatically, by means of suitable drive means, etc. prevent or prevent.
• 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 system also allows you to activate and lock keys individually. With mechatronic locking devices, additional flexibility in the locking organization can be achieved.
• the electronically controlled locking system is based on data transmission between an electronic module on the key side and an electronic module on the lock side.
• This data transmission can be done by touch - for example by means of electrical contacts on the key and lock - or without contact - for example by means of electromagnetic induction - take place.
• Data can be transferred in one or both directions.
• the transmitted data is used to check whether the inserted key is authorized to access. If this is the case, a lock-side motor is activated, which electronically controls a locking element in such a way that it releases the lock cylinder or the lock.
• Such a locking device is known for example from international laid-open specification WO 98/28508 or from international laid-open specification WO 01/21913.
• a disadvantage of such locking devices according to the prior art is that, in the event of manipulation attempts, it is sufficient to overcome the locking of the locking cylinder caused by the locking element. This can be done through shock, vibrations, brute force or otherwise.
• Locks But there are other, purely mechanically trained locks, for example doors to individual rooms inside the building.
• the object of the invention is therefore to provide a mechatronic locking device which protects against external influences, in particular against violence. Vibrations and / or shock effects or magnetic effects, is resistant and ensures safe functioning.
• the object is achieved by the locking device and the method as defined by the claims.
• the locking device has a coupling element and an output element that can be brought into operative connection with locking means. It can be brought into a first and a second coupling state by electronically controlled drive means via propulsion means which move the coupling element.
• the rotor - that is, the component of the lock that can be rotated by key, door handle or similar means - is decoupled from the output element in the sense that there is no direct coupling via the coupling element or other coupling means that would cause the rotor to rotate causes a movement of the output element.
• the clutch element couples the output element to a rotor which can be actuated by key, door handle, doorknob or a comparable means or by an electric drive.
• the approach according to the invention therefore differs from the prior art in that it is not simply a matter of uncoupling the rotor and the housing, but rather that Coupling the output element with the rotor - and possibly also decoupling from the housing.
• This allows the coupling means - here the coupling element - to be selected in a very simple manner in such a way that the coupling only occurs when the coupling means is in a single, singular state.
• the coupling element or locking element can be deflected from its rest position during manipulation attempts, for example by knocks. In the event of a manipulation attempt, this is exploited by manipulating through a large number of impacts until the blocking element is in the free position.
• the locking device is influenced in such a way that the blocking element which is once in the free position is immediately fixed in it - for example by a torque which constantly acts on the rotor.
• the likelihood that the coupling element will accidentally get into the second coupling position can be further reduced by a back-driving force which causes the coupling element to tend to be moved away from the second coupling position corresponding to the second coupling state.
• the mechanical decoupling of the rotor and output element in the first coupling state also has the advantage that the lock cannot be actuated even by violent turning of the rotor: the rotor turns at most empty.
• the output element is blocked in relation to a housing in the first coupling state. This also locks it against rotation.
• the coupling element can have an at least partially spherical surface - and can be designed, for example, as a ball. This minimizes the number of positions in which it couples - which is advantageous as described above. There is then a requirement that a shear line between the elements to be coupled and the equator of the coupling element are aligned. If the equator of the coupling element is above or below the shear line, the coupling element is pushed away from the coupling position by exerting force on one of the elements to be coupled.
• the coupling element is preferably neither coupled to the housing nor to the rotor. The coupling element can then be rotated in its second coupling position. of the rotor.
• the drive means can, for example, shift the coupling element between two coupling positions - corresponding to the two coupling states: in the first coupling position, the coupling element couples the housing and the output element, while it does not effect a coupling between the rotor and the output element. In the second clutch position, it couples the rotor and the driven element, but does not effect a coupling between the housing and the driven element.
• a propulsion means of the drive means serving as a blocking element can block the output element in relation to the housing in the first coupling state.
• the coupling element couples the rotor and output sleeve.
• the blocking element and coupling element are designed and arranged in such a way that the blocking element, when it is moved from the second to the first coupling state, simultaneously moves the coupling element away from the coupling position by direct or indirect action.
• Another alternative provides that the output element is not blocked against the housing even in the first coupling state. This is advantageous if the output element is, for example, firmly connected to an inner door handle. In this embodiment, on the one hand, it is ensured that a person inside the object to be locked can always leave the object. On the other hand, this direct coupling between the output element and the inner door handle also provides a certain protection against manipulation - after all, the inner door handle must be moved with every attempt at manipulation.
• An electric motor with a lifting spindle can be used as the drive means.
• electric motors are relatively economical electricity consumers.
• they are largely vibration, shock and magnetic resistant due to their design.
• the coupling element can be “quasi-positively guided” or even completely positively displaceable by the drive means. This means that the position of the coupling element between the first and the second coupling position is defined at all times by the drive means, for example by being connected to the propulsion means of the drive means. In the case of quasi-forced guidance, this connection can only be released with a certain amount of force; it can be the case, for example, that the propulsion means and / or the coupling element has a permanent magnetic moment, and as a result the coupling element adheres to the propulsion means. In the case of forced guidance, the connection is so firm that it cannot be detached by normal impacts.
• the coupling element is fixed to the propulsion means by mechanical connections; the mechanical connections are released, for example, as soon as the coupling agent is in the second coupling position.
• the locking device can thus be designed in such a way that the coupling element is always on one of two predetermined tracks: on the first track quasi-positively or positively guided between the first and the second clutch position, and rotated on the second track by the rotor and relative to this in a constant position around an axis of the rotor.
• the drive means can 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 in the direction of the first coupling position by mechanical action against a spring force. This can prevent damage caused by violent manipulation attempts and in the event of a drive failure. If the coupling element is in an - undefined - position between the first and the second coupling position and force is exerted on a shear line, the coupling element deflects in the direction of the first coupling position without causing damage.
• Locking device - in the event that it is used with a locking cylinder - can have a key blocking element which can be moved from a first position to a second position by inserting the key into the key opening, the key being only pulled out in the second position 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 non-vertically oriented key.
• this can ensure that the system is always in a defined position when the key is removed, in which the coupling element can be moved between the two coupling positions.
• the key blocking element blocks the rotor in the first position against rotation so that it cannot be moved away from its defined position by a screwdriver or similar means or by randomly induced movements.
• a screwdriver or similar means or by randomly induced movements.
• the key blocking element - together with the coupling element - means that there are a total of three defined states:
• An unauthorized key is in the first clutch state and the key blocking element releases the rotor.
• the rotor is freely rotatable, but does not actuate the bolt. The key can only be removed in a defined position of the rotor.
• the authorized key is inserted: second coupling state, the rotor is rotatable and its rotation causes the bolt to be actuated.
• the key blocking element can be, for example, a rocker arm which is connected to a spring which brings about a restoring force towards the first position.
• the additional security which is brought about by the above elements, has the consequence that the locking device, for example, does not need any purely mechanically actuated tumblers.
• a locking device according to the invention can thus be used with any existing locking systems can be combined and used across plants.
• the locking device allows multiple systems to be connected and used in several systems with a system-neutral key.
• a locking device according to the invention can also additionally have mechanical tumblers.
• the locking device according to the invention is therefore system-neutral: mechanical and mechantronic system components can be completely separated.

• FIG. 1 A principle on which an embodiment of the invention is based is shown in FIG.
• an output element 4 designed as an output sleeve the axis of rotation of the rotor can be rotated and can be brought into operative connection with a driver, which is designed to actuate locking elements, so that the bolt - if necessary, if certain requirements are met - rotate through of the output element 4 can be operated.
• Both the rotor and the stator each have a recess 2.1, 3.1, which are aligned with a recess 4.1 in the driven element in the arrangement shown.
• a coupling element 5 is located in the opening which is formed by these cutouts.
• the coupling element 5 ball is formed.
• it could also have a different shape, for example a pin with a partially spherical surface or a pin.
• the principle of operation is as follows: The coupling element is displaceable through the opening means, not shown. 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 clutch state.
• the coupling element couples the output element to the stator. It prevents the output element from rotating and thus prevents the bolt from being actuated.
• the coupling element does not effect a coupling between the rotor and output element when it is in the first coupling position.
• the rotor and output element and thus also the rotor and bolt are therefore decoupled when the coupling element is in the locked position. This is different from the prior art, where a lock is caused by the rotor being locked against the stator.
• the clutch element 5 is in a second clutch position - or free position - when it is located on the shear line S2 between the rotor and the driven element. This is the second clutch state.
• 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 - corresponding to the first and second coupling state - displaceable, the coupling element 5, 5 'in a first coupling position
• Output element 4 locks against the housing and in a second clutch position, the output element 4 couples to the rotor 2, the rotor 2 not being coupled to the output element 4 when the clutch element 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 an only partially spherical surface.
• the recess 2.1 in the rotor is limited in this embodiment, for example, such that the coupling element only couples the rotor 2 and the driven element 4 when it is inserted into the opening as far as it will go. If the coupling element is retracted somewhat, it is pushed back towards the first coupling position due to its partially spherical surface when the torque is applied.
• another surface shape can also be provided, which causes such a repulsion - for example a conical shape, etc.
• the condition that is actually to be fulfilled in this embodiment is that the shape of the coupling element is such that it has a region in which it tapers steadily.
• the depth of the recess 2.1 in the rotor is so limited that the coupling element in its second coupling position is also at a stop or almost at a stop can also be present in the case of a spherical coupling element.
• FIG. 3 shows the set of all states 11 very schematically.
• the coupling element is guided through the cutouts mentioned and can only be displaced in 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 lock to be opened is provided with the reference number 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 direction or the other with a torque acting on the rotor. This fact has the effect that the subset 12 of the states in which a release takes place is very small. With random movements, the probability almost disappears that the coupling element gets into the release position (the second coupling position).
• FIG. 3 The lower diagram of FIG. 3 relates to the structure according to FIG. 2. This differs from that of FIG. 1 in that the coupling element in its second coupling position is also at a stop.
• the subset 12 of the states in which a release takes place is therefore entered at the very edge. In this case too, it is small in comparison to the set of all states, since the coupling element is also pressed away from the coupling position with a torque on the rotor if it is not exactly positioned in the coupling position.
• FIG. 3 thus explains how the measures described bring the probability of success in manipulation attempts to a very small value using statistics alone. Additional measures can further reduce this probability of success.
• the tacking effect with which the coupling element is virtually fixed in the first coupling position can be brought about, for example, by a ferromagnet, but other means can also be used, for example clamping or gluing or mechanisms similar to Velcro fasteners. Further mechanisms are conceivable, such as, for example, the T-slots described in US Pat. No. 4,103,526 for mechanical tumblers or dovetail-shaped slots.
• the source of the restoring force can also be a ferromagnet, for example.
• the cylinder lock partially shown in FIGS. 4 and 5 has a double locking cylinder 1 with a first partial cylinder 1.1 intended for an outside of the door and a second partial cylinder 1.2 intended for an inside of the door (optional).
• the second partial cylinder 1.2 is only shown schematically in the figure.

• the wing element 22 is mechanically coupled to an output element 4. This can be coupled either to housing parts or the stator 3 or to the rotor in the manner already explained.
• the coupling element 5 used for this purpose is spherical in the example shown.
• the coupling element can be displaced between the first coupling position (FIG. 4) and the second coupling position (FIG. 5) by drive means 23. In the first clutch position, the equator of the clutch element is located on the shear line between the output element and the stator, in the second clutch position on the shear line between the output element and the rotor.

• the communication means for the communication between data carrier and electronic module can be designed in a manner known per se for contactless communication via electromagnetic radiation, or the key can also have contacts which can be contacted via contact pins of the cylinder lock. Other communication options are conceivable.
• the electronic module determines - for example also in a manner known per se - on the basis of data exchanged with the data carrier of the key, whether the key authorizes access to the locked object. If authorized, the electronic module controls the drive means so that they bring the coupling element into the second coupling position and release the lock (FIG. 5).
• the key holder can then cause the output element 4 to rotate with a rotation of the key, the coupling element rotating in the opening formed by recesses 2.1, 4.1 of the rotor and the output element.
• the output element 4 effects actuation of locking elements via wing element 22 and driver 21.

This is supported in the figure by a pivot 25 on the rotor 2 and is held in its first position by spring means 26 when no further forces are acting. In the first position it stands up against the stator 3 and blocks the rotor 2 in a standard orientation against rotation. By inserting a key, it can be brought into its second position against the spring force. This releases the blockage of the rotor and the rotor can be rotated freely.
• a first extension 24.1 on an end face 3.2 of the stator prevents the key blocking element 24 from returning to its first position.
• the drive means 23 will be described in more detail. It has an electric motor 40, by means of which a drive shaft 41 can be set in rotation. On the drive shaft 41, a lifting spindle 42 is placed along this linearly displaceable. In the drawing, an intermediate part 43 is shown between the drive shaft 41 and the lifting spindle 42. A permanent magnet 45 is inserted in the screw element. A drive sleeve 47 is mounted on the electric motor 40 with a spring 46, with guide elements 48 protruding through slots in the screw sleeve of the lifting spindle 42.

• the coupling element 5 is guided between its first and its second coupling position. If a force acts on the coupling element in the direction of its first coupling position - that is, in the figure towards the bottom - then the coupling element 5, the lifting spindle 42 and the driving sleeve 47 give way due to the action of the spring 46 against the spring force. As already explained, such a force can arise as a result of a torque acting on the rotor when it acts when the coupling element is between the two coupling positions.

• the person skilled in the art will recognize many other possibilities of how a rotary movement of an electric motor is converted into a propulsion movement, for example, as in the present case by means of a screw gear. Variants without an electric motor are also conceivable, for example a magnetic actuator.
• the role of the permanent magnet 45 will be briefly explained here.
• the ferromagnetic domains form in the ferromagnetic material in such a way that the magnetic field runs continuously in the transition between the magnetized body and the ferromagnetic material. If the material and the body are separated by even a short distance, such a continuous course is no longer possible, so energy must be used to separate the material and body. This creates something like an 'adhesive effect', which is known to anyone who has ever played with permanent magnets.
• this effect is used to effect a quasi-forced guidance: the coupling element 5, for example containing iron cobalt and / or nickel, can only be detached from the permanent magnet by massive impacts; a high speed.
• This "adhesive effect” is further enhanced if the coupling element has a flat surface, as shown in FIG. 2.
• a second effect is the long-distance effect: the permanent magnet exerts a certain attractive force on the coupling element 5, as a result of which a restoring force arises, the advantages of which have already been discussed above.
• the permanent magnet also permits a cylinder installation position rotated in comparison to the illustrated embodiment, for example by 180 °.
• the embodiment shown in FIGS. 7 and 8 differs from that of FIGS. 1-2 and 4-5 in that the coupling element in the first coupling state lies inside the rotor.
• the blocking of the output element 4 with respect to the housing is effected by a blocking element which corresponds to a propulsion means 42 - for example a lifting spindle 42 as shown in FIG. 6 - and is moved into an opening in the output element in the first coupling state.
• This first coupling state is shown in FIG. 8.
• the coupling element 5 is located completely within a circumferential line of the rotor 2. In the first coupling state shown in FIG.
• the coupling element is placed in such a way that its equator is located on the shear line between the rotor and the output element 4 and thus couples the rotor and the output element (second coupling position) ,
• the lifting spindle 42 is retracted in this second coupling state, so that the output element can be rotated.
• an inner and an outer holding element 52 which cause the coupling element to remain in the second coupling position even when the rotor is rotated and, for example, the force of gravity (when rotating through 180 °) would move the coupling element against the inside of the rotor ,
• the mode of operation of this embodiment is as follows: In the first coupling state (FIG. 8), the lifting spindle 42 blocks the output element 4 against the housing.
• the coupling element does not prevent rotation of the rotor, unless other means (key blocking element or the like) prevent rotation of the rotor, it is freely rotatable, but has no effect (FIG. 8, lower picture).
• a transition to the second coupling state is, for example, only possible if the system is in the oriented orientation according to FIG. 8, upper picture, which can be brought about again by a key blocking element.
• the lifting spindle is withdrawn in an electronically controlled manner, which causes the coupling element to be moved into the second coupling position, for example by gravity, a magnetic force as in the preceding examples and / or by a force acting on the exterior of the holding elements 52 and of this passed through the inner holding member 52 spring force.
• the rotor can be rotated and the output element is coupled to it: the bolt can be actuated.
• the outer holding element 52 is - for example initially pressed in by a spring force - within an outer circumferential line of the driven element and, when the driven element is rotated away, is held within this outer circumferential line by a housing or stator.
