B. a door or a door frame, in which Receiving opening an open to the door gap between the door and door frame Cassette is attached, and with the lock housing inserted into the cassette and is releasably attached therein.

Such lock arrangements are known for example from US 4,696,174 and particularly suitable for use in security areas, the Locks to operate the latch or bolt in addition to mechanical components can also have electrical components. Details on the construction of an electrically operated lock for use in security areas are e.g. from the German utility model 200 09 716 known. This electric lock enables that in addition to its Opening and closing the basic functions related to the trap also various Status checks. For example, an electrical detection element is provided, with which you can check whether the lock housing is within a corresponding Opening of the door or the wall surrounding the door. In the event of unauthorized removal of the lock from the receiving opening, use the of the detection element a signal output.

Although the security lock according to the German utility model 200 09 716 meets high requirements in terms of safety, that is Replacement of the lock, for example with a similar lock, relatively time-consuming.

The invention has for its object to provide a lock arrangement for a security lock that allows easy replacement of the lock while maintaining a high security standard against unauthorized manipulation.

To solve this problem, it is proposed in a lock arrangement of the type mentioned that there is an intermediate space between the lock housing and an upper and / or lower narrow side wall of the cassette, in which an element rigidly fastened in the cassette is arranged, the distance to the lock housing being smaller is the distance between the narrow side wall and the lock housing, and that a detection element which triggers a signal when approaching or at a distance from the element is attached to the lock housing.

The lock case of the lock is not immediately in the receiving opening of the door, the door frame or the surrounding area Building wall used, rather there is a to in the receiving opening cassette open to the crack in the door. The lock housing is inserted into this cassette and releasably attached therein, thereby replacing the lock with one another lock of the same design is particularly simple and in a short time is feasible. This lock arrangement is also advantageous for inspection and Maintenance work on the lock if it is only briefly out of the cassette removed, checked and then reinserted into the cassette becomes.

The lock arrangement is also advantageous for the manufacturer with the security lock door to be provided. This is relative in the choice of connection dimensions free, provided there is only sufficient installation space for after the door has been manufactured cassette to be fastened therein is provided. The accuracy of the connection dimensions does not have to be considered by the door manufacturer, this is rather alone It is the responsibility of the lock and cassette supplier.

According to a preferred embodiment, it is proposed that the side walls the cassette with openings for the passage of the lever handle axis and / or the locking cylinder are provided. It is also proposed that that the cassette in the region of its open end face with fastening tabs and that the lock housing with the fastening tabs is screwable.

The cassette can be manufactured particularly cheaply from simple sheet metal parts, if the cassette consists of two side walls and at least one lower and an upper narrow side wall, and the fastening tabs one-piece bends of the lower or upper narrow side wall are. The cassette is preferably designed such that the fastening tabs stick out from the cassette.

With the aim of particularly easy fastening of the cassette in the cutout the door, the door frame or the wall surrounding the door can be used by anyone Fastening tab with at least one opening through which one the cassette in the opening e.g. the screw fixing the door can be put through is.

To prevent unauthorized use of the cassette with the lock is expanded, it is proposed with a preferred embodiment of the invention, that the opening is covered by the faceplate of the lock housing.

The authorized or unauthorized removal of the lock from the cassette is particularly easy simply check by placing between the lock housing and one there is a space between the upper and / or lower narrow side wall of the cassette, in which an element rigidly fixed in the cassette is arranged, the Distance to the lock housing is less than the distance of the narrow side wall to the lock housing, a on the lock housing when approaching the or distance from the element signal-triggering detection element attached is. The element is preferably a pin that coincides with its two ends against the side walls of the cassette.

According to a preferred embodiment of the lock arrangement a connector strip is fastened in a rear wall of the cassette into which the Engage corresponding electrical contacts of the lock. hereby can the electrical connection between the lock and e.g. one central switching and monitoring point in a particularly simple manner by the lock housing is pushed horizontally into the cassette serving as the receiving pocket becomes. With this insertion is the electrical Connected. Conversely, this electrical connection with the Pulling the lock out of the cassette serving as the lock pocket is interrupted, what is immediately missing in the monitoring station as electrical Signal is registered and thus noticed. It also reduces the electrical Plug connector the time required for the replacement of the lock.

Details of the construction of the cassette based on an exploded view of the same.

Central component of the lock arrangement shown in Figures 1 to 3 is an electrically operated lock with a box-shaped lock housing 1 and a faceplate 2 forming the end face of the lock housing 1. The faceplate 2 completely covers the lock housing 1 from the outside, with only one opening remains, through which the bolt 4 of the lock is passed. The bar 4 is mounted horizontally on the guide pin 3, which is on the inside of the Lock housing 1 are attached. A bolt head 5 of the bolt projects in the usual way 4 out of the faceplate 2 of the lock housing, provided that the bolt 4 in its closed position. The bolt head 5 is provided with a bevel 6, since the bolt 4 in the described embodiment also the Functions as a trap and therefore it is also referred to as a "bolt trap" leaves.

About further, arranged on the lock housing 1 guide pin 9 is in the Lock housing an actuating part 10 stored. The actuating part 10 performs a translatory movement parallel to the direction of movement of the bolt 4.

There is also an electric motor 11 in the lock housing a motor mount 13 which can be pivoted about a pivot axis 12 fixed to the housing arranged. The electric motor 11 engages with appropriate electrical control into a tooth structure of the operating part 10, whereby this is withdrawn. Details of the design and the interaction of electric motor 11, bolt 4, locking element 8 and actuator 10 are in the German utility model specification 200 09 716.

The lock with the lock housing 1 is not located directly in a receiving opening the door or the door leaf, but only indirectly. This is the Lock housing 1 inserted into a cassette 14 serving as a lock pocket, the in turn arranged and fastened in the receiving opening of the door 15 is. The cassette 14, which is preferably made of sheet steel, is composed of vertical ones Side walls 16, an upper narrow side wall 17, a lower one Narrow side wall 18 and a rear wall 19 together. Between the Lock housing 1 and the upper and lower narrow side walls 17 and 18 respectively there is a horizontally extending space 20. In this space 20 elements 21 are arranged in the form of pins, which are related to their support both ends against the side walls 16 of the cassette 14. The Distance of the pins 21 to the outside of the lock housing 1 is less than the distance a of the narrow side walls 17, 18 to the lock housing 1.

To the door gap between the door 15 and that not shown in the drawing The cuboid-shaped cassette 14 is open while the door frame all of its other walls are closed except for openings provided therein. On the rear wall 19 of the cassette 14, a tab 22 is formed, which for Attachment or additional attachment of the cassette 14 in the corresponding Cutout in the door 15 can serve.

Details of the construction of the cassette 14 are shown in Figure 5. The cassette consists of two main parts, one of which is shown on the left in FIG Part of the side wall 16, the rear wall 19, the lower narrow side wall 18 and the upper narrow side walls 17 includes. Separated from this is the other one, in Figure 5 right side wall 16. Parts of the upper and lower Narrow side walls 17 and 18 are bent into tabs 23 and 24, respectively stand out from the cassette 14 and in the plane of the front open Face of the cassette. The tabs 23, 24 serve the one hand Attachment of the cassette 14 in the corresponding recess in the door, and on the other hand, the fastening of the lock with the lock housing on the Cassette 14.

The two side walls 16 have openings 25, 26 for the passage of the lever handle axis or the lock cylinder of the lock. The back wall 19 is provided with a preferably rectangular opening 27 in which one electrical connector 28 is attached. The electrical cables of the power strip 28 are moved from there to the inside of the door.

Finally, the pin-shaped elements already described can be seen in FIG 21, which are supported against the side walls 16 of the cassette. This support is not immediate, but indirect via reinforcement struts 29, which are provided with bores 30 into which the peg-shaped ends of the pin-shaped elements 21 engage and so the cassette 14 in the lateral direction strengthen.

Figure 4 leaves the individual parts described above in their mutual assignment detect. Both the cassette 14 and the lock with the lock housing 1 are in a slightly pulled out of the door 15 position shown. Screws 32 are inserted into bores 31 of the two tabs 23, 24, which connect the two tabs and thus the cassette 14 to the door. Further holes 33 in the two tabs 23, 24 are used Attachment of the cuff 2 to the cassette 14, and thus the connection of the Lock with the cassette. This connection is also by appropriate Screws 34 made. The arrangement of the bores 31, 33 is in the form that after screwing the lock into the cassette, the edges of the cuff 2 cover the holes 31. In this way, the cassette 14 can only then be removed when the lock has been completely removed.

According to Figure 1, the lock is provided with a contact strip 35, which is due to the horizontal insertion of the lock into the cassette 14 with its contacts in the corresponding contacts of the connector strip 28 engages, thereby immediately and without electrical connection work the electrical connection of the Castle is made.

At the upper edge of the lock housing 1 is a detection element designed as a button 36 arranged. A sensing element of the detection element 36 lies here if the lock is properly fastened in the cassette, to one of the Pins 21 on, and in this way signals the correct installation of the Castle. As soon as the lock is pulled out of the cassette 14, takes place a release of the switching contact in the detection element 36, and thus one Signal delivery.
