Abstract

Lock has an electronic interrogation device (21) which, following an electronic inquiry, responds via a transponder by asking for an authentication. If authentication is received, an electric control of a locking element (26) is activated to release the lock. An antenna is held in the rotating lever (14) of the lock for use with the transponder, and the lever also has a pressure sensitive switch with it. Electrical control of the locking element (26) is achieved by movement of the lock bar (7) between a locked and released position.

Description

The invention relates to a lock, in particular for a locking system, with one inside a door a locker or the like attached housing from a turntable protruding through the door relocatable latch.

Such locks have been on the for many years Market known. It is about the turning handle a key for a lock cylinder. The Only then is the locker door locked possible if the door is open on the inside the same castle attached a corresponding coin is thrown in. After closing the door you can by means of the key representing the turning handle the bolt will be locked. That the turning handle the performing key is then deducted and accompanied the user, for example, when visiting a bathing establishment.

The invention has for its object a generic Lock more user-friendly and tamper-proof to design.

This task is first and foremost a lock with the features of claim 1 solved, based on one after activation an electronic interrogator and subsequent Querying the locking authorization of a transponder electrical control of an auxiliary locking element to provide for the release of the closing actuation, being used for activation in the antenna for transponder polling carrying rotary handle one on rotation and / or pressure sensitive switch is provided.

As a result of such a configuration is a generic Castle of increased utility value created. On Is the key to locking the bolt back and forth not necessary anymore. Accordingly, one of Key channel accessible from the outside of the door of a locking cylinder, which is penetrated by Super glue, objects etc. are disabled can be. The castle now contains one electronic interrogator. The latter is through one housed in the turning handle, on rotation and / or pressure sensitive switch activated so that a transponder interacting with the handle an antenna incorporated into the rotating handle after the Locking authorization can be queried. Is this given this is how the locking auxiliary element is controlled electrically to release the closing operation. For example, transponders and electronic interrogators interact in such a way that each Lock and each representing a single locking element Each transponder has a lock identity code memory and / or have a key code memory and each individual lock only then by means of such an individual locking element or transponder can be closed, if lock identity code and / or key code match each other correspond. The lock's key code memory and / or the lock identity code memory of the Transponders are erasable and writable memories such that when the lock is operated for the first time of the lock in the lock identity code memory of the individual locking element and / or the key code of the single locking element in the key code memory of the castle is written. It can therefore only the lock using the transponder be unlocked, which also brings about the locking Has. It can preferably be provided that the Key code memory of the lock when operated twice is deleted. This turns the castle into one Brought ready, so that a following Visitors with another transponder the castle close and occupy the locker. It can however, it should also be provided that each transponder is assigned to a single lock of the locking system. The transponder and associated lock then carry the same Numbers. To solve the invention task also contributes the fact that the locking aid a tumbler from a bolt locking relocation lockable position in a releasable Position controls. The locking aid element is for this purpose from an electromagnet from a door lock not enabling first position in a a second position enabling a door lock relocatable. In detail, it looks like the control via a dead center shift of a transmission spring he follows. It is also provided that the bolt lockable against spring tension of a return spring is. This makes it easier to close the bolt after a previous query of the transponder on its Lock authorization. An imperative to take the Riegel for the turning handle is simple realized in that the rotary handle over a Crank pin is coupled to the bolt. This looks in Detail so that the bolt due to a dead center position the crank pin is held. Attacking on the bolt Pushback forces are therefore via the crank pin passed into the lock housing, so that high push-back forces are damage-free. Defined end positions of the locking auxiliary element are thus that the bolt when in the second position Auxiliary locking element by snapping the tumbler in a bolt-side tumbler notch the default position is maintained. This is done thereby over the dead center position Transmission spring. It can be provided that the armature of the electromagnet in each of its end positions due to the dead center of the transmission spring is held. This is an alternative that the electromagnet is a self-holding magnet is in the one position by permanent magnetic forces and in the other position via an anchor pressure spring is held. So for the electromagnet only for moving the anchor in one or the other Direction an energy surge necessary, so that one For example, incorporated energy storage in Form of batteries is spared. To the castle of To be able to switch left to right is a Allows turning the bolt. So that this can be realized is the one entering the guard locking recess Locking extension of the guard locking in the middle of the lock arranged. Finally, there is an advantageous feature still in it, an arranged in the rotary handle, especially multi-colored light emitting diode for status display to be provided when operating the transponder. Lights up the LED green, this indicates that the lock is properly locked or unlocked. The color red indicates if there is an error, for example an incorrect transponder is used in an attempt to close becomes. A mixed color of the LED indicates if e.g. the batteries are no longer sufficiently charged are so that the personnel are instructed to change the battery to make.

The lock designated as a whole with the number 1 is Part of a locking system, not shown, for example a bathing establishment. There are the Locker doors equipped with such locks. Each lock 1 is fixed on the inner surface a locker door illustrated with a dash-dot line 2. In particular, the lock 1 has a box-like Lock housing 3. A lock cover, not shown covers the castle interior. In front of the castle floor 4 of the lock housing 3 arises a guide pin 5, which passes through a longitudinal slot 6 of a bolt 7. Its locking head 8 is in a locking recess 9 guided a side wall of the lock housing 3. The aforementioned longitudinal slot 6 is located in the the bolt head 8 adjoining the bolt tail 10. This is the carrier of a pin projection 11 on which one end of a return spring designed as a tension spring 12 attacks. The other end is at a castle floor Pin 13 set. This will Bolt 7 always loaded in the release direction.

A rotary handle is used to close the bolt 7 14, which one with the castle ceiling not shown associated bearing sleeve 15 is assigned. This passes through a hole in the locker door 2. The rotary handle 14 is in coupling connection with one Crank pin 16, which in turn a transverse to Direction of displacement of the bolt 7 extending transverse slot 17 interspersed. By shifting rotation the handle 14 can therefore in the transverse slot 17 engaging crank pin 16 of the bolt 7 pre-closed against the force of the return spring 12th

The handle 14 then includes a schematic illustrated antenna 18 for querying the locking authorization of a transponder 19. There is a coin-like one Design of the transponder 19 before. For example can be assigned to a bracelet in order the transponder 19 during the visit to the bathing establishment on the body of a person.

Alternatively, it is possible to use a coin type instead Transponders 19 a key element in card form to train. Again, it is possible to use the card-shaped To hold the key element with a bracelet. It also lends itself to having the transponder in one to integrate a watch provided with a bracelet under realization a multiple function.

Inside, the handle 14 takes one to rotate and / or pressure sensitive switch 20, which after a corresponding actuation one below of the bolt 7 located in the lock housing 3 electronic Query facility activated. This is in electrical Lead connection with one also below of the bolt 7 arranged electromagnet 22, the rod-shaped armature 23 can be moved back and forth. A cross pin 24 of the protruding end of the armature 23 passes through a transverse to the direction of displacement of the anchor 23 directed slot 25 of a one-armed Locking auxiliary element 26. To the end Storage of the same serves a lock housing side Articulation pin 27. The free end of the locking auxiliary element 26 is equipped with a support pin 28 to which one end 29 of a torsion spring Transfer spring 30 is set. The other End 31 of the transmission spring 30 comprises a support pin 32 also a one-arm tumbler 33. This is also mounted around the pivot pin 27. On its upper edge facing the bolt 7 forms the Tumbler 33 a locking extension 34 to cooperate with a latch-side locking recess 35. When anchor 23 is moved outwards, the corresponding the locking auxiliary element 26 taken away. Through the Transfer spring 30 becomes the tumbler 33 in the downward direction pivoted and in this in a stop position held in which the locking extension 34 beyond the displacement path of the guard locking recess 35 of bolt 7 lies, cf. 1 and 4.

The electronic interrogation device 21 is fed and the electromagnet 22 from in a battery compartment 36 housed batteries, not shown, which Battery compartment 36 on the outside of the lock base 4 by this runs out.

It is possible without using a transponder 19 by means of the handle 14 over the crank pin 16 den Lock bar 7, against the force the return spring 12. Reached in the pre-closing position the crank pin 16 is a dead center position to its fulcrum, and seen in the closing direction of the bolt. In this, however, the bolt is not locked 33 secured. One of the rotary handle 14 incorporated multicolored light emitting diode 37 can then be in color light up red to indicate that the Castle.

Locking a previously occupied locker requires therefore an activation of the electronic interrogation device 21 by the associated with the rotary handle 14 Switch 20. This is done by rotation and / or pressure on the turning handle 14. That of the turning handle 14 supplied transponder 19 is below including the antenna 18 on its locking authorization queried. If this is the case, the electrical one Control of the electromagnet 22 instead, which pulls the anchor 23 inward and thereby the locking auxiliary element 26 in a clockwise direction. Here, the transmission spring 30 comes into a Fig. 5 illustrated dead center position, which by the dead center line T-T is predetermined. Have in this the ends 29, 31 of the transmission spring 30 the least Distance from each other. After crossing the dead center line T-T loads the transmission spring 30 Tumbler 33 counterclockwise such that it with its locking extension 34 against the bottom of the Bolt tail 10 bumps. Now the bolt 7 over the turning handle 14 and the crank pin 16 are pre-locked, so the tumbler 33 snaps in the final phase of the Latch advance shifting in the area of the guard locking recess 35 on and blocks the bolt rear shifting. With this in accordance with regulations When the latch is closed, the LED lights up for a status display with green on.

It is now not without the associated transponder 19 possible to close the bolt 7. The transponder 19 has in its memory, not illustrated recorded the lock identity code of the lock, while the memory of the electronic interrogator 21 added the key code of the transponder 19 Has. Using another transponder therefore the lock 1 does not open. Can also by means of which now has the lock identity code of the lock Transponders no other lock of the locking system be operated.

The closing of the bolt 7 needs as for pre-closing the use of the associated transponder 19. This is against the end face of the turning handle 14 placed under pressure on the turning handle, what the activation of the interrogator 21st according to. After detection of the locking authorization of the Transponders 19 is the electrical control of the Electromagnet 22, the armature 23 in the outward direction drives and the locking auxiliary element 26 pivots. Via the transmission spring 30, which is the dead center position exceeds the tumbler 33 from its locked position pivoted to bolt 7 so that by turning the Rotary handle over the crank pin 16 of the bolt 7 is closable, the latter by the return spring 12 is supported.

If the LED lights up in a mixed color, then this gives the supervisory staff information that the State of charge of the batteries of the respective lock is insufficient. It is then a replacement of the used ones Batteries required for new ones.

Regarding the electromagnet 22, it is a self-holding magnet in the locked position through permanent magnetic forces and in the other Position, i.e. release position, via an anchor pressure spring is held. So electrical energy is only for the change in anchor position required, resulting in a Protection of the batteries contributes.

All the features disclosed are essential to the invention. In the disclosure of the application is hereby also the Disclosure content of the associated / attached priority documents (Copy of the pre-registration) in full included, also for the purpose, characteristics of this Include documents in claims of this application.
