Description

The The invention relates to an electronic lock cylinder according to the Preamble of claim 1 specified type.

Electronic lock cylinders are used in particular on doors. From the WO 2005/001 224 A1 a generic electronic lock cylinder is known which has a cylinder body which can be used in mortise locks of doors. A handle on the outside of the door, often in the form of a knob, an axis is moved, which is rotatably mounted in the cylinder body and leading to the inside of the door. The axis is partially in a rotatable sleeve which is rotatably connected to the lock cam. A coupling unit driven by a motor can assume two states: in its driving state, it establishes a rotationally fixed connection between axle and sleeve, so that in this state the lock can be actuated via the external handle. If, on the other hand, it is in its freewheeling state, the axle and sleeve can be rotated independently of one another. In this state, the axle rotates freely, so that the lock in this state can not be operated from the outside of the door.

Over a Reading unit can Electronic permissions from the outside of the door into the system be entered. If they are considered valid, the engine becomes controlled, which then moves an actuator which the coupling unit brings into their driving state. This condition is time limited maintained. Subsequently he drives Motor returns the actuator to its original position, causing the coupling unit is brought back into its freewheeling state.

in the The state of the art are solutions known to work with a solenoid instead of a motor. These have - compared with a motor solution - the principal Disadvantage that they constantly in the driving state of the coupling unit power pull. Electronic lock cylinders are battery powered. That's why lock cylinder Do not stay in the driving state for a long time with the solenoid, because otherwise their battery would be emptied too fast. Consequently can lock cylinder with solenoid not equipped with the feature "optional continuous access" become. For this reason, the invention is not such systems include. These were therefore already in the preamble of the claim 1 excluded.

In the DE 102 35 201 A1 a solution is shown in which coupling unit and motor are installed in the outer knob. Such an arrangement is questionable for safety reasons, since safety-critical components on the outside of the door are too easily vulnerable.

In the EP 0978 611 A2 describes a system in which motor and coupling unit are housed together in the inner knob. A similar arrangement can be found in the WO 2004/020767 A1 , These solutions are safe in terms of safety. But they have the disadvantage that for the inner knob a large design must be chosen, which is problematic for aesthetic reasons on the market.

In the WO 03/078766 A1 a solution is shown in which the engine is housed in the cylinder body. Together with the actuator, reading unit, evaluation / control unit and battery, the motor is one of the electrically relevant components of the system, which must be wired together if no radio interference-prone radio components are to be used. It is therefore advisable to install all elements to be wired either together in stationary parts of the system or to arrange all these parts with the axis co-rotating, otherwise sliding contacts would have to be used for the transfer, which are very problematic in continuous use. In this respect, it is a disadvantage to install the engine in the cylinder body.

In the DE 196 15 775 C2 an electronic lock cylinder is described, which has a cylinder body, a rotatably mounted in the body and leading to the inside axis, a rotatably mounted in the body locking cam and obviously an outside and inside handle. The inside handle is continuously connected via a sleeve with the locking cam (column 3, lines 20-32) and the outside handle is rotatably connected via an electronically controlled coupling unit with the sleeve and thus with the closing cam, said coupling by means of an electric motor is carried out. Motor and coupling unit are to be regarded as arranged within the axis.

In the DE 103 29 969 A1 is also an electronic lock cylinder with cylinder body, continuous axis, inside and outside handle and electric motor driven coupling unit described.

Of the Disadvantage of the two aforementioned solutions is that the inside handle always rotatable with the locking cam is connected, so that with the inside handle always closing operation is possible. With such a solution Thus, no variant of the lock cylinder can be offered in which also the inside handle rotates freely and only after Entering a valid Authorization to operate of the cam is docked.

The The object of the invention is an electronic lock cylinder imagine, in which the assembly is simplified and a length adjustment when mounting on the door allows becomes.

These The object of the invention is characterized by the characterizing features of Claim 1 in conjunction with its generic features met.

Advantageous is now that outside knob, Axis, coupling unit and motor can be built as a solid unit, the in the final production checked can be used and when installed in the door as a complete unit can be. Another advantage of this solution is that the Axis towards the inside of the door easily extendable is what a system with length adjustment when mounting on the door allows.

By characterized in claim 2 measures is advantageously achieved that from the inside of the door her constant Usability of the lock possible becomes.

By characterized in claim 3 measures is advantageously achieved that also on the inside of the door an operation of the lock is only possible after entering a valid authorization.

Further Advantages, features and applications of the invention result from the following description in connection with in The embodiment illustrated in the drawings.

The Invention will be described below with reference to the drawing Embodiment described in more detail. In the description, in the claims, the abstract and in the drawing, the list given in the back of the reference numerals used terms and associated reference numerals. It demonstrate:

1 Electronic lock cylinder in cut side view and cutaway top view.

1 shows an electronic lock cylinder, especially for use in doors. He has a cylinder body 8th which can be used in mortise locks of doors. Via an outside knob 4 at the outside of the door becomes the axle 3 moved in the cylinder body 8th is rotatably mounted and leads to the inside of the door. The axis 3 partially runs in a rotatable sleeve 9 , which rotates with the locking cam 6 connected is.

The coupling unit 2 and the engine 1 are co-rotating in the axis 3 arranged. The actuator 10 is by the engine 1 over a spindle 11 indicating the rotational movement of the motor 1 in an axial linear movement, axially moved, wherein the actuator 10 can take two positions. Depending on the position of the actuator 10 If the coupling unit can assume two states: in its driving state, it provides a rotationally fixed connection between the axle 3 and sleeve 9 ago, so that in this state the lock on the outer handle 4 can be operated. Is the coupling unit 2 while in their free-wheeling state, axle can 3 and sleeve 9 be rotated independently. In this state, the axis turns 3 freely through, so that the lock can not be operated in this state from the outside of the door.

Via a reading unit 12 electronic permissions can be entered into the system from the outside of the door. Are they through an evaluation / control electronics 13 as valid, the engine is 1 controlled, then the actuator 10 moves, which thereby the coupling unit 2 brings into their driving state. This condition is maintained for a limited time. Then the engine drives 1 the actuator 10 back to its original position, whereby the coupling unit 2 can fall back into their freewheeling state. The power supply of the lock cylinder supplies the battery used in the inner handle 14 , Evaluation / control electronics 13 and battery 14 are in a cage 15 built-in, which is rotatable within the inner handle 5 built-in and non-rotatable with the axle 3 connected is.

All electrically relevant components of the cylinder - namely reading unit 12 , Actuator 10 , Spindle 11 , Engine 1 , Evaluation / control electronics 13 and battery 14 - are with the axis 3 built in co-rotating. Therefore, they can be permanently wired together reliably via a - not shown in the drawing - cable connection. The use in the long-term behavior problematic sliding contacts can therefore be completely avoided.

All safety-critical components are either in the range of cylinder body 8th or in the inner handle 5 built-in. In the outer knob 4 is only the safety-critical non-critical reading unit 12 accommodated. Against external attacks becomes the axis 3 through a drill protection 16 and the cylinder body 8th through a drill protection 17 protected. Mounted with a security fitting, the electronic locking cylinder therefore offers a high degree of protection, making it possible to use it even in the highest risk classes.

Since in the outer knob only the Leseein Ness 12 and in the inner knob 5 only evaluation / control electronics 13 and battery 14 must be accommodated, the two knobs can be realized in an aesthetically convincing size.

From the arrangement according to the invention there are further advantages: outer knob 4 , Axis 3 , Coupling unit 2 and engine 1 can be assembled as a solid unit which can be finally tested at the end of the manufacturing process. When installed on the door, it can be used as a complete unit from the outside of the door, minimizing the likelihood of functional damage from being mounted on the door.

One Another advantage of the solution shown is that the Axis towards the inside of the door simply designed and therefore extensible in a simple manner What can be designed is what a system with length adjustment to the individual Door strength at the Mounting on the door becomes conceivable.
