Abstract

The electronic cylinder lock has engine (1) and coupling unit (2) which are arranged within the axle (3). The cylinder lock has a coupling unit which produces a torque proof connection between axle and sleeve (9) in an attachment state and in the free running state the axle and sleeve can swivel independent from each other and engine is formed as an electronic drive for actuator. An independent claim is included for arrangement.

Description

The The invention relates to an electronic lock cylinder in particular for Use on doors. He has one Cylinder body, in mortice locks of doors can be used. Over a Handle on the outside of the door, often in the form of a rotary knob, an axis is moved, which is rotatable in the cylinder body is stored and the up to the inside of the door leads. The axis runs partly in a rotatable sleeve, the non-rotatable with the locking cam connected is. A motor driven coupling unit can be two states occupy: in its driving state, it provides a non-rotatable connection between axle and sleeve ago, so that in this state, the lock on the outer handle are operated can. If, on the other hand, it is in its freewheeling state, axle can and sleeve independently to be turned around. In this state, the axle rotates freely, so that the lock in this state from the outside of the door are not operated can.

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.

such electronic lock cylinder are known from the prior art.

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 "optional continuous access" feature. For this reason, the invention is not intended to include such systems. These have therefore been excluded in the preamble of claim 1.

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 also be found in 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 WO 03/078766 A1 shows a solution in which the engine is housed in the cylinder body. Of the Engine belongs together with actuator, reading unit, evaluation / control unit and battery to the electrically relevant components of the system, to each other need to be wired as far as no - interference-prone - radio components should be used. It is therefore recommended to wire all Either incorporate elements together in dormant parts of the system or to arrange all these parts with the axis co-rotating, otherwise for the transmission Sliding contacts would have to be used in continuous use are very problematic. In that sense, it is a disadvantage to the engine in the cylinder body install.

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 in which all electrically relevant parts are wired and are arranged co-rotating with the axis, as a constraint It should be noted that the design of the knobs is not too big should. Mandatory should also be aware that safety critical components of the system not in the outer knob may be arranged.

The The object of the invention is achieved in that the motor and coupling unit be installed together in the axle.

The characterized in claim 3 measures effect advantageous that outside knob, axis, Coupling unit and motor can be built as a fixed 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 4 measures is advantageously achieved that from the inside of the door her constant Usability of the lock possible becomes.

By characterized in claim 5 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.

The invention is described below by way of example with reference to the drawing of 1 described.

It demonstrate:

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 external knob ( 4 ) on the outside of the door, the axis ( 3 ), which 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 ), the rotation 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 controlled by the engine ( 1 ) via a spindle ( 11 ), which determines the rotational movement of the engine ( 1 ) in an axial linear movement, moves axially, wherein the actuator ( 10 ) can take two positions. Depending on the position of the actuator ( 10 ), the coupling unit can assume two states: in its entrainment state, it provides a non-rotatable connection between axis ( 3 ) and sleeve ( 9 ), so that in this state the lock on the outer handle ( 4 ) can be operated. Is the coupling unit ( 2 ) in their free-wheeling state, axis ( 3 ) and sleeve ( 9 ) are rotated independently. In this state, the axis rotates ( 3 ) freely, 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 detected by an evaluation / control electronics ( 13 ) is valid, the engine ( 1 ), which then drives the actuator ( 10 ), which thereby the coupling unit ( 2 ) brings into its driving state. This condition is maintained for a limited time. Then the engine ( 1 ) the actuator ( 10 ) 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 ) which is rotatable within the inner handle ( 5 ) and rotatably with the axis ( 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 area 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 ) housed. Against external attacks, the axis ( 3 ) by a Bohrschutz ( 16 ) and the cylinder body ( 8th ) by a Bohrschutz ( 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.

Because in the outer knob only the reading unit ( 12 ) and inside knob ( 5 ) only evaluations / control electronics ( 13 ) and battery ( 14 ), 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.
