Abstract

The system has a key with a first memory element (4) and electronics with which a coupling element can be operated to enable operation of the lock if a valid key is inserted. A validated second memory device (5), into which data for the key to be validated are loaded, is used to program the lock for key validation.

Description

The invention relates to an electronic mechanical Locking system for locking cylinders without locking mechanism for actuation a locking lug for locks with its own locking system system containing a key with a first storage element and electronics, by means of which a coupling element is actuated is a barcode when using a key recognized as authorized Allow actuation of a lock.

Mechanical locking systems are known, which are quite complex Represent systems and a considerable effort for calculation and manufacturing. In addition, there is a lot of effort Key loss because all locking cylinders have to be changed.

Proceeding from this, the invention is based on the object electronic-mechanical locking system of the type mentioned hend further training that in addition to easy handling of the closure high security and easy change of the process Authorization is realized. The locking device is intended to be a com compact and also have a break-proof construction. The the entire locking device should fit in one door fitting.  

This object is achieved according to the invention in that as Lock cylinder in front of a locking lug mounted on the mortise lock is seen, in which an actuating pin engages positively, the arranged on the coupling element with an outside on the fitting neten rotary knob is detachable.

An advantageous embodiment is that at the insertion closed a ver with a locking cylinder fastening screw connecting bridge is fastened with bearing bolts on the bearing blocks are arranged on which the locking lug is mounted.

It is also advantageous that the fitting or the outer plate Chambers for the processor, capacitor, batteries and the like.

It is also proposed that the coupling element on the outside shield is stored.

The proposed electronic mechanical locking system draws is characterized by a simple and reliable construction and enables the specification and modification of the Access authorization.

The invention is based on particular in the drawings gene illustrated embodiments explained in more detail. Show it:

Fig. 1 is a schematic representation of the impact in a Be integrated closing device,

Fig. 2 shows a section through the electronic-mechanical locking system in an exploded view and

Fig. 3 is a perspective view of the system in an explosion-like representation.

Fig. 1 shows schematically the locking device arranged on the fitting 1 , which contains a processor 3 for reading out a first memory element 4 and a second memory element 5 on a circuit board 2 . The first memory element 4 is designed in particular as a ROM chip and the second memory element 5 as a RAM chip. The reading or the electrical connection of the two memory elements 4 , 5 takes place via a contact point 6 , which is connected to the printed circuit board 2 via a line 7 serving as a data bus. The circuit board 2 also contains a further memory 8 , a clock 9 , which is preferably designed as a DCF 77 radio clock, and an emergency charging electronics 10 . The further memory 8 connected to the processor 3 is provided for capturing locking messages, such as key data, time and date. The fitting 1 contains a battery 11 for supplying the entire electronics. An auxiliary power source 12 , preferably a capacitor, is provided for receiving the electrical energy for an emergency opening. A coupling element 14 , which is designed in particular as a magnetic coupling, is connected to the printed circuit board 2 or electronics via a further line 13 . The coupling element 14 is assigned to a change pin 15 , which is connected on the one hand with a rotary knob 38 and the like and on the other hand via an actuating pin 40 with a closing element, in particular a locking nose 44 . If by means of the processor the first storage element and thus an authorized key has been recognized, the coupling element 14 is activated for a predetermined time of a few seconds in order to release an actuation of the lock.

With regard to the mechanical structure of the locking system, the fitting has an outer shield 1 which is provided with individual chambers for receiving the processor 3 , the capacitor 12 or the batteries 11 . In addition, the arrangement of a contact pin 16 in connection with an insulation sleeve 17 and the fastening by the nut 21 is shown.

The electrical coupling element 14 has an interchangeable pin 15 toward the outer shield 1 , which engages in the rotary knob 38 , the bearing being carried out in an insert 39 and specifically in a bearing 41 formed there , this insert being inserted in a bore in the outer shield 1 . This insert 39 is provided towards the rotary knob 38 with a shoulder 48 as pull protection and is supported on a projection 50 of the outer shield 1 . This projection 50 is covered by a material overhang 42 by means of the rotary knob 38 .

On the opposite side of the coupling element 14 , an actuating pin 40 is arranged, which engages in a locking lug 44 with a square inner cutout. This locking lug 44 actuates a lock, for example a self-locking mortise lock 37 , but it is possible to use all locks which can be actuated via locking cylinders. For storage of the locking lug is a connec tion web 45 , which is held by means of the fastening screw 51 provided with such mortise locks, with which locking cylinders are usually fastened. Bearing bolts 52 are provided on both sides, on which bearing blocks 46 are non-rotatably fitted, between which in turn annular disks 53 are provided which support the nose 44 .

The system is covered on the inside by means of an inner plate 18 and can be actuated from the inside by means of a pusher 43 with a change pin 49 . The outer shield 1 is covered on the inside with a cover plate 47 . With this configuration of the outer shield 1 , the system can be preassembled, which makes assembly easier. After the actuating pin 40 performs a rotary movement, it is expedient to accomplish the electrical connection 54 via slip rings. Both the outer plate 1 and the contact pin 16 are made of hardened steel.
