Description

The invention relates to a lock with a correspondingly contoured insertion opening in the lock housing wall and lockable therein by means of a fixing screw profile lock cylinder which has an electrical control line to be influenced by the associated key, which with an existing electrical control system in a door lock via a releasable current-carrying Connection is electrically connected, which consists of contacts and counter-contacts fixedly arranged on the surface of the lock cylinder on the one hand and inside the lock, which automatically come into mutual contact when the lock cylinder is locked in the lock insertion opening, in particular for door locks with electronic key control.

Door locks of the above type are known from AT-PS 320 466. Their associated keys are not only mechanically coded, namely provided with conventional key incisions or countersinks, but also additionally equipped with a non-mechanical coding which controls the electrical control or. Attempted to recognize the electronic system and, in accordance with the codes stored therein, released the lock bolt for its key actuation, otherwise blocked it. This significantly increases the security of the lock. Such door locks also allow the lock bolt actuation to be released or blocked only at certain preset times and / or for different time periods. While others, e.g. B. through the magazine "Baubeschlagmagazin 11/84, p.192" known door locks with electronic key control the releasable current-conducting connection between the profile lock cylinder and the door lock consists of a flexible power cable that is led out of the interior of the lock and by means of one at its free end Plug must be plugged into a socket on the radially projecting reading head of the profile locking cylinder, which still requires a rather disadvantageous manual operation and always requires the lock fitting to be removed for the respective replacement of the locking cylinder, that is. Generic door lock according to AT-PS 320 466 advantageously already procured so that the contact located on the narrow side of the profile cylinder web at the level of its faceplate threaded bore when inserting and locking the profile cylinder in the lock insertion opening with the counter contact located in the interior of the lock, designed as a spring tongue Current contact arrives, so that no additional manipulations are necessary when the profile cylinder is removed and removed. The flexible connection cable between lock and profile cylinder that is otherwise required is no longer required. The fetching electrical contact between the lock and the profile cylinder can easily lead to contact difficulties, especially since the final installation position of the profile cylinder in the lock insertion openings is subject to fluctuations depending on the lock fitting used, which often leads to corresponding misalignments of the profile cylinder in the lock insertion openings.

The invention is therefore based on the object to provide an electrically controllable door lock with a built-in profile lock cylinder of the type mentioned, which while maintaining its power connection contact between the lock and the profile cylinder, which occurs automatically when the profile cylinder is installed, ensures a permanently secure and also independent of any inclined mounting positions of the profile cylinder Power line contact between lock and cylinder guaranteed. This object is achieved in that the profile cylinder through the faceplate screw on the one hand and a U-shaped clamping bracket which can be adjusted transversely by the latter and which engages around the web of the profile cylinder, the contacts on the profile cylinder in its area encompassed by the clamping bracket and the mating contacts on the the Leg of the clamping bracket facing away from the screw. As a result, when the profile cylinder is installed in the door lock, there is a permanent, firm contact between the door lock and the profile cylinder, which at the same time also allows a certain amount of installation play between the cylinder and the lock. This built-in movement is important in practice because it is not uncommon to compensate for misalignments that occur between the profile cylinder perforation of the mortise lock and the door fitting. It is regularly carried out in such a way that when the door fittings are attached, the forend screw holding the built-in profile cylinder is first loosened in order to be able to adjust the profile cylinder to the fittings, the profile cylinder having a corresponding inclined or. Can take an imbalance. Then the faceplate screw is on again drawn. The fixed current contact between the profile cylinder and its clamping bracket, which surrounds it firmly, is not impaired by all this installation work.

The contacts on the profile cylinder advantageously consist of exposed areas of power lines which are insulated on both sides of its webs in the profile cylinder. The contacts in the profile cylinder can be designed as plug-type sliding contacts and the sliding counter-contacts on the clamping bracket can consist of appropriately arranged plug pins.

However, it is even more advantageous if the contacts on the profile cylinder and the mating contacts on the clamping bracket as contact or. Counter-contact surfaces are formed, between which there is a conductive rubber body bridging the contact distance and fastened to the clamping bracket. Such conductive rubber bodies consist of a multiplicity of lead wires embedded in non-conductive rubber and laid parallel and next to one another at a small distance. They ensure a secure electrical contact between the contact surfaces on the profile cylinder and the mating contact surfaces on the clamping bracket.

The door lock 1 shown in FIG. 1 is of conventional construction in that it has a lockable and lockable bolt 2, a snap-in latch 3, a lock nut 4 with a handle insertion opening 5 and a profile locking cylinder 8 that can be inserted into a correspondingly contoured insertion opening 6 in the lock housing wall 7 contains, which can be clamped in the axially aligned state by means of the face screw 9 and the clamping bracket 10 which is in screw thread engagement with the latter. For this purpose, the clamping bracket 10 is limitedly displaceable via an existing projection 10 'protruding into a slot 7' of the housing wall 7 and provided on its leg 10 'facing away from the fixing screw 9 with a clamping mandrel 10''which provides the clamping end 9' opposite the faceplate screw 9 at a variable distance. In the clamping fastening of the profile cylinder 8 shown in FIG. 1, the faceplate screw end 9 ′ and the clamping mandrel 10 ″ ′ in the web 8 ′ of the profile cylinder 8 have counterbores 8 ″ arranged centrally opposite one another, as a result of which the profile cylinder 8 is held axially centered in the lock 1 . To release this clamping attachment, the faceplate screw 9 only needs to be actuated in the release direction, whereby it unscrews from the thread in the leg 10 ^{IV of} the U-shaped clamping bracket 10. By means of the compression spring 11, the clamping bracket 10 together with the faceplate screw 9 is pressed to the right, the faceplate screw end 9 'initially still remaining in the countersink 8 ", whereas the clamping mandrel 10"' with the increasing displacement movement of the tensioning bracket 10 from its associated countersink 8 "in Profile cylinder extends The clamping bracket 10 finally comes into its right stop position in the slot 7 'of the door lock, while then the faceplate end 9' moves to the left to release the profile of the lock insertion opening 6 and thus the profile cylinder 8 for its removal.

The profile cylinder 8 is provided with a key channel 12 and conventional mechanical pin tumblers, which are not shown and which can be actuated when the suitable key is inserted by means of its mechanical coding in the form of the conventional key incisions or notches or can be moved into the front position in which the core 13 of the profile cylinder 8 are rotated per se and thus its closing thumb 14 could move the latch 2 accordingly by engaging in the closure 2 '.

The door lock shown is additionally provided for an electronic key control with a built-in electrical control system, not shown, which is connected via the power supply lines 15 to a detector 16 (see FIG. 2) on the profile cylinder 8, which in turn has an existing key and to be brought into contact-free energy and data transmission with its non-mechanical coding. For this purpose, between the profile cylinder 8 containing the detector 16 and the control or. Electronic system and its connecting lines 15 a releasable current-conducting connection can be created. This basically consists of on the locking cylinder 8 on the one hand and on the clamping bracket 10 on the other hand fixed contacts and counter-contacts which automatically come into mutual current contact when the locking cylinder 8 is inserted or locked in the lock insertion opening 6.

For this purpose, the existing contacts on the profile cylinder 8, as shown in FIGS. 2, 4, 6 and 9, can be formed simply from the externally exposed locations 17 by storm lines 17 'which are insulated in the profile cylinder 8, in particular on both sides of its web 8', which are formed in substantially longitudinal milling or drilling channels 18 or 19 of the profile cylinder 8 filled with plastic or the like insulating material are laid and lead to the detector 16 arranged therein on the end face.

In the embodiment shown in FIG. 7, where the profile cylinder 8 can be determined or clamped in the manner shown and described in connection with FIG. 1 via the clamping bracket 10 and the faceplate screw 9, are in the profile cylinder 8 in the attack area of the clamping bracket 10th , namely between the countersink 8 "and the drive pinions 14 'of the cylinder cores, there are socket-type sliding contacts 20, the individual sockets. 20' being connected via the power lines 17 'to the detector 16 arranged on the end face. In this case, the sliding counter-contacts consist of plug pins 21, which are electro-insulated on the leg 10 ″ of the clamping bracket 10 facing away from the faceplate screw 9 and are connected via the lines 16 to the electronics system present in the interior of the lock. If, starting from the inserted, but not yet determined, installation state of the profile cylinder 8 shown in FIG. 7, the faceplate screw 9 is actuated in the sense of the clamping attachment, its end 9 ′ comes to rest in the countersink 8 ″ present on the profile cylinder 8 the clamping bracket 10 with its leg 10 "increasingly moves against the profile cylinder 8, the plug pins 21 moving into the sockets 20 'and thereby ensuring a proper current-conducting connection between the profile cylinder 8 and the electronics system of the lock 1.

It goes without saying that the sliding contacts in the lock cylinder may also be present on only one side, although their arrangement on both sides has the advantage that the installation position of the cylinder in the lock can be disregarded.

In the embodiment shown in FIGS. 10 to 13, the contacts on the profile cylinder 8 and the mating contacts on the clamping bracket 10 are formed as mutually opposite contact surfaces 25 or mating contact surfaces 26, between which there is a conductive rubber body 27 bridging the contact distance and fastened on the clamping bracket 10 located. Such a conductive rubber body 27, as shown in FIG. 12, consists of non-conductive rubber 28, in which a multiplicity of thin, essentially parallel conductor wires 29 are embedded. Each wire leads from one side of the rubber to the opposite side.

Each contact surface 25 consists of several contacts 25 ', which are connected via the lines 17 to the detector 16 on the profile cylinder 8, the number of contacts depending on the particular application. The individual contacts 25 'can also be designed differently. If their number on one side of the profile locking cylinder 8 is not sufficient, then, as in Flg. 10 shown, a contact surface can also be installed on both sides of the profile cylinder.

The counter-contact surface 26, as shown in particular in FIG. 13, advantageously consists of the ends 26 'stripped from the upper side, stripped in a insulating layer 30, of parallel flat conductors 26 ". This group of flat conductors is together with its insulating layer 30 according to FIG. 10 on one of the faceplate screws 9 opposite end 10 "of the clamping bracket 10 attached Kungsstoffhalterung 31 attached, which also carries the conductive rubber body 27. For this purpose, a receptacle opening 31 'for the conductive rubber body 27 is provided on the front side in the plastic holder 31, while behind the receptacle opening 31' there is a slot-shaped recess 31 "for the correspondingly angled end 26 'of the flat conductor array which forms the counter-contact surface 26 and projects into it.

The plastic holder 31 is placed in a fork shape on the clamping bracket end 10 ″ and fastened by means of the screw 32, which runs coaxially to the forend screw 9 and at the same time serves as a clamping mandrel. By tightening the faceplate screw 9 after the axial insertion of the profile locking cylinder 8 into the lock insertion openings, the profile locking cylinder 8 is also firmly clamped here via the clamping bracket 10, with the faceplate screw end 9 'and the other in the corresponding recesses 8 "of the profile cylinder Clamp the cone 32 'of the clamp screw 32 firmly. With this clamping fixture, however, there is also a permanently solid, electrically conductive connection between the contact surface 25 on the profile cylinder and the mating contact surface 26 on the clamping bracket 10, namely via the correspondingly slightly compressed conductive rubber body 27.

As further shown in FIG. 10, a further plastic holder 33 with a flat conductor array forming a counter-contact surface 26 and a guide rubber body 27 arranged in front of it can also be provided on the end of the tensioning bracket 10 facing the forend screw 9. This plastic holder 33 can be pressed by a positioning screw 34, which is also to be actuated from the faceplate of the lock, with the guide rubber body 27 carried by it, against the contact surface 25 of the profile cylinder 8 facing it, so that here, too, there is a permanently fixed current contact between the contact surfaces 25, 26 results on the guide rubber body 27.
