EP1736622B1 - Lock cylinder - Google Patents

Description

The invention relates to a lock cylinder with a knob, and a lock cylinder housing, in which one side or both sides rotatably mounted by means of the knob knob shaft is rotatably mounted, and with electrical and / or electronic and / or magnetic and / or electromagnetic and / or electromechanical and / or mechanical functional elements, to which at least one closing element and at least one electromechanically operating coupling means, the locking member rotatably connected to the knob shaft and / or releases the knob shaft to actuate a lock, as well as an evaluation include due to an authorization signal due to an input or a Input signal generates the authorization signal. The unilaterally actuable lock cylinder may be formed as a half cylinder.

Such lock cylinders are well known. Often, the arrangement is such that the input signal is detected by means of an antenna that excites a transponder in a chip or similar token worn by the accessing person. The received input signal contains the access code, which is evaluated by the transmitter. In the case of an access authorization, an authorization signal is generated, which activates an electromechanical coupling means. The coupling means causes a rotationally fixed connection between the closing element, such as a locking lug, and the knob or releases the knob shaft. An actuation of the lock or a switch or the like is then possible with the lock cylinder.

The DE 103 28 297 A1 describes the arrangement of a locking lug on a rotary sleeve which is freely rotatably mounted on the knob shaft. In the knob shaft, the coupling means is arranged, which drives a driver in a recess of the rotary sleeve due to the permission signal. Thus, the locking lug is rotatably connected to the knob shaft. The DE 198 51 308 C2 discloses a lock cylinder operable on both sides by a knob. The transmitter and the antenna for receiving a wirelessly transmitted signal are arranged in the knob on the inside of the door.

The arrangement of the transmitter in the knob has the disadvantage that it is relatively easily accessible and manipulated there. Also, the space in the knob can then no longer readily be used for other functional elements, in particular for reading units for detecting the input signals or for communication units or for larger batteries. The knob then builds relatively large and can not be mounted on all doors, especially not on frame doors. Also has a large knob a little appealing visual appearance.

From the EP 1 256 671 A2 It is known to arrange the evaluation electronics in a rosette. This has the disadvantage that as a rule slip ring contacts must be provided in order to transmit electrical signals between mutually rotatable modules can. Such slip ring contacts are often weak points under harsh operating conditions and interfere with the smooth operation of a lock cylinder.

document US 2004/007032 discloses an electronic lock for replacement replaceable core locks, the lock having a magnet assembly with a solenoid and a piston which is longitudinally parallel to the axis of rotation of the cylinder of the lock.

document EP 1 443 162 discloses a lock cylinder, in particular profile cylinder, with a shaft, a substantially concentric with the shaft member and a coupling arrangement for coupling the shaft with the component, wherein the coupling arrangement at least one coupling element between a coupling position, in which the coupling element, the shaft and the Component in the direction of rotation form-fitting manner with each other, and a Entkuppelposition is displaceable, in which the shaft and the component are uncoupled in the rotational direction of each other, and having a drive which is adapted to move a drive member, thereby to displace the coupling element. In this case, at least one permanent magnet is arranged on the drive member and / or on the coupling element, which is designed to move the coupling element during a movement of the drive member.

The invention has the object of providing a lock cylinder of the type described differently. In particular, the disadvantages of the above-mentioned prior art should be avoided.

The object is achieved according to the invention by the features of claim 1.

According to a particular embodiment of the invention is further provided that in the knob at least one electrical and / or electronic and / or magnetic functional element is arranged, which is electrically connected to the functional elements in the knob shaft in the mounted position. The knob rotates with the knob shaft, so that also knob located and the on the knob shaft located in the functional elements no slip ring contacts are required. Rather, a completely assembled knob shaft can be provided with one or two knobs, all functional elements for the electromechanical actuation of a lock cylinder thus done without slip ring contacts. Trouble-free operation is therefore guaranteed.

According to a particular embodiment of the invention is further provided that in the knob at least one electrical or electronic or magnetic functional element is arranged, which is electrically connected to the functional elements in the knob shaft in the mounted position. The knob rotates with the knob shaft, so that even between the located in the knob and located on the knob shaft functional elements no slip ring contacts are required. Rather, a completely assembled knob shaft can be provided with one or two knobs, which has all functional elements for the electromechanical actuation of a lock cylinder. The lock cylinder housing then only serves as a bearing for the knob shaft.

The functional element in the knob may comprise an energy source. It is expedient if the functional element in the knob comprises a reading unit for detecting an input or receiving an input signal which is in communication with the evaluation electronics. The knob is located in an exposed position on the door and is therefore suitable for receiving a reading unit.

It can also be provided that the functional element in the knob comprises a communication unit which is in communication with the evaluation electronics. Thus, a programming of the lock cylinder or its evaluation electronics can be performed.

Preferably, the reading unit or the communication unit are configured to generate an access signal that from the transmitter can be evaluated or read out immediately. This has the advantage that different reading units can be combined with a single evaluation electronics. Thus, knobs with reading units with different reading technologies, input means or the like, or communication units with different interfaces, such as infrared interface, contact plug or radio interface, can be kept ready, which can be modularly combined with the knob shaft. It can be assembled to the environmental conditions or user requirements optimized lock cylinder.

It can be provided that the reading unit or the communication unit via an identification code or signal is assigned to the evaluation electronics. This can be transmitted with the access signal. It can also be provided that an identification code must be transmitted during the installation of a reading unit or communication unit or must be retrieved by the evaluation electronics. By the identification code, the reading unit of a specific evaluation and thus a specific lock cylinder is assigned uniquely. Only when the identification code on the one hand and the access signal on the other hand are correct, the authorization signal is generated. This prevents a simple replacement of the reading units for unauthorized actuation of locks.

According to the invention, it is provided that the knob shaft consists of at least two and preferably of a plurality of segments, which are rotatably connected to each other, and that at least one functional element is arranged in at least one segment. This significantly increases the versatility and flexibility for producing a lock cylinder. It can be provided with different functional elements segments, which can nevertheless be combined into a knob shaft. It is provided for the knob shaft, a modular system whose components can be selected and combined according to the requirements.

The segments may be formed as sleeves or shaft pieces whose end edges have interlocking projections and recesses. In this case, at least one segment is formed as a terminal segment and carries the knob or is provided with a receptacle for the knob. It is particularly useful if the recesses and projections on the opposite end edges of at least one segment and in particular all lying between the terminal segments lying in the mounted position segments are arranged and arranged so that the segments are arbitrarily joined together. Thus, a virtually arbitrarily trained knob shaft can be assembled with different functions, since always each segment can be combined with any other segment, which together form a uniform knob shaft. Only the terminal segments can only be joined together on one side with other segments.

It may be useful if the segments are glued in the mounted position. This allows a particularly strong connection between the individual segments. But it can also be provided that the segments are locked together in the mounted position and / or jammed. This allows a detachable connection so repairs or replacement of segments is possible.

Furthermore, at least the terminal segments of the assembled knob shaft can be mounted axially fixed in the lock cylinder housing and hold the segments arranged therebetween between them. Then no connection between the segments would be required.

According to the invention, at least the evaluation electronics are arranged in at least one segment. In another segment, at least the coupling means can be arranged. Finally, a third type segment can be provided which carries the closing element. Of course, a plurality of functional elements or only parts of a functional element can be arranged in a segment. For example, it can be cheap to provide the evaluation electronics in one segment and the coupling means with the closing element in another segment. The closing element may comprise in a known manner a closing lug which is rotatably connected to the knob shaft by means of a locking pin driven by the coupling means.

It is also conceivable that both the evaluation electronics and the coupling means and the closing element are arranged in a segment. In a further segment, for example, the battery can be arranged. A segment carrying at least one functional element can also be designed as a terminal segment.

It may be expedient that the segments have different lengths. Thus, depending on a set of segments of different lengths with the coupling agent, with the evaluation electronics and the like can be provided. It is expedient, however, if at least one segment is designed as an extension segment which can be mounted between any two segments. Then only one type of segment needs to be provided for each or several functional elements. The desired length of the knob shaft for different length lock cylinder can then be formed generated by one or more extension segments.

As explained above, all electric, electronic or electromagnetic functional elements are on the knob shaft or in the co-rotating knob. A slip ring assembly is no longer required. Nevertheless, the functional elements for the signal flow must be connected to each other. For this purpose, it can be provided that at least a part of the segments each have at least one cable channel for at least one having electrical cable which is at least flush with the cable channel of the adjacent segment. This is particularly necessary for the extension segment, so that a cable can be easily guided to the nearest segment with functional element.

However, it may also be expedient if the segments have transmission means for transmitting an electrical signal or a current from one adjacent segment to the other adjacent segment. This is also necessary in particular for the extension segment, so that an electrical connection can be effected from a functional element in one segment to a functional element in another segment. The segments preferably have corresponding transmission means with electrical contacts, which cause the electrical connection when joining adjacent segments. This can be achieved that the extension segments need to be inserted depending on the desired length in a simple manner between the other segments, whereby at the same time the required electrical connection of the functional elements in the segments is effected.

The illustrated in the drawing knob shaft 11 for a double knob cylinder, which is actuated on both sides with a knob, consists of a plurality of segments 12, 13, 14, 15, which are rotatably joined together. In detail, the arrangement is such that between the terminal segments 12, 15 a plurality of segments can be inserted until the desired length of the knob shaft is reached. The lying between the terminal segments 12, 15 segments 13, 14 have corresponding projections 16 and recesses 17, which engage positively in the assembled position and cause the rotationally fixed connection. The projections and recesses on the opposite end faces 18, 19 of the segments 13, 14 always match one another, so that the inner segments 13, 14 can be assembled as desired.

The lock cylinder comprises a plurality of functional elements for electromechanical actuation of a lock, not shown. The functional elements required for this purpose include a coupling means which, on the basis of an authorization signal, connects a closing element 20 in a rotationally fixed manner to the knob shaft 11, an evaluation electronics 21, which generates the authorization signal on the basis of an input signal, and, for example, a reading unit 22 for receiving the input signal wirelessly. Also, a battery 23 is required to power the electrical or electronic functional elements.

In the embodiment shown in the drawing, the evaluation electronics 21 is arranged in the terminal segment 15. The coupling means 30 is mounted in the segment 14 for this purpose, the segment has a corresponding installation space 24, in which, for example, an electric motor with eccentric 31, an electromagnetic drive or a rotary magnet can be arranged. It is a pin 32 reciprocated in an opening 25, which engages in a recess of the closing element 20 and causes the rotationally fixed connection.

The battery 23 is housed in the knob 26 which is rotatably connected to the terminal segment 15. The reading unit 22 with antenna 27 is disposed in the opposite knob 28 which is rotatably connected to the terminal segment 13. The projections 16 of the terminal segment 13 fit into the recesses 17 of the segment 14 or the opposite terminal segment 15. The projections 16 of the segment 14 fit into the recesses 17 of the terminal segment 15th

To extend the knob shaft extension segments 13 are provided, which can be inserted between the individual segments 12, 14, 15. For this purpose, they have corresponding projections 16 and recesses 17, each with the recesses 17 and Projections 16 of another segment 12, 13, 14, 15 cooperate. This allows an arbitrarily long knob shaft to be mounted.

Frequently, however, the arrangement will be such that the central segment 14, which carries the coupling means and the closing element 20, so in the lock cylinder, which is the closing element with the usual locking lug in the region between the two cylindrical seats of the lock cylinder housing. Depending on the length of one or the other recording of the lock cylinder housing connects to one end directly to the terminal segment 12 with the knob 28 at. As shown in the drawing, between the segments 12, 15 still an extension segment 13 is present to form a longer knob shaft.

The same applies to the opposite side of the middle segment 14. Here is also an extension segment 13 is present, which is inserted between the segment 14 and the terminal segment 15. For longer Knaufwellen multiple or longer extension segments 13 can be installed. Preferably, a grid of 5 mm is provided because the lengths of the recordings of the lock cylinder also vary in 5 mm increments. The shortest recording length for today's lock cylinders is 30 mm. It is therefore appropriate that the common longitudinal portion of the middle segment 14 and the terminal segment 12, which is in the installed position in the receptacle, is no longer than about 30 mm. Otherwise, the terminal segment would have to be designed to receive the coupling agent. The same applies to the opposite segment 15th

Accordingly, all electrical and electronic functional elements are present on the knob shaft and rotate with it. For signal transmission and power transmission between the functional elements cables can be provided which are guided by corresponding cable channels 29 of the individual segments. the cable channels 29 of the individual segments are in the mounted position in alignment, so that a passage of one or more cables is possible. Alternatively or additionally, permanently installed electrical conductors can also be present in the segments and in particular in the extension segments, which in the mounted position cause electrical signal transmission via aligned contacts.

It is hereby provided a knob shaft, which can be adapted in a simple manner to different length lock cylinder housing. the knob shaft is ultimately composed of several individual functional segments, which can be combined with uniform extension sleeves or directly to obtain the desired knob shaft with the desired functions and the desired length. In the knobs further functional elements can be arranged, which interact with the functional elements in the knob shaft. A modular system is created that can be extended and changed in almost any desired way to fulfill the desired functions.
