FIG. 4 shows the double latch mount of FIG. 3 after assembly.

The lock according to the invention consists of its on a door leaf fastened part from a plate 1 and a cover 2

609817/0808

existing housing, which on its outer part with a knurled Button 3 is provided, which enables the closing operation of the interior by a lock cylinder 4, which is from the outside by a Security key is accessible, which can actuate the lock cylinder 4 via an opening 5.

According to the invention, the housing attached to the door leaf cooperates a double bolt receiver together, which is attached to the door frame and the details of which are shown in FIGS. the the arrangement forming the latch receptacle consists of two horizontal ones and superimposed plates 6 and 6 '.

The attachment of these plates is shown in FIG. Each plate 6, 6 'in turn consists of two plates which are arranged in pairs at 7 and 7' for the plate 6 and at 8 and 8 'for the plate 6 ^1. Each half plate 7, 7 ', 8, 8 ¹ is formed by bending an angle profile on the leg by 90. The arrangement thus consists of a central angle profile 9 and two outer, upper and lower angle profiles 10 and 11, respectively.

These angle profiles are fixed on the door frame, being bolted, screwed or welded. The angle irons come from a single piece and are formed from a metal cut off and formed without welding. Every tile we <

Chen is made by bending it by 90 of the lengthening leg

The assembly is assembled so that the platelets are side to side. In this way, the two plates 7 and T form the perforated bolt receptacle 6. The small plates 6 and 6 'forming the bolt receptacle penetrate the housing through gaps arranged on the plate 1. These horizontal gaps 12, 12 'are provided on the plate 1 and are positioned and designed in such a way that, when the door leaf is closed, they fit on the plates 6 and 6' which are currently positioned in the housing.

609817/0806

As can be seen in Fig. 3, the. Plate a medium square Recess 13, 13 *, which are arranged in pairs to accommodate Latches 14, 14 'is provided. The double bolt 14, 14 'works with the double formed by the plates 6 and 6' Bolt receiving arrangement together and is in turn formed from two originating from the plate 15 L-shaped extensions. The plate 15 is mounted vertically displaceably in the housing and for this purpose has a central cutout 16 and two upper and lower ones lower cutouts 17 and 17 ', which are provided with guide lugs 18, 18' or 19, 19 'work together.

The plate 15 carrying the bolts 14, 14 'is controlled by a cam 20 operated, which cooperates with the lock cylinder 4, which in turn either of the inner knurled button 3 or of adjusted with a security key.

The cam 20 comes into contact with a cutout via the nose 21 22 'of the plate 15. The rotation of the cam 20 causes the displacement the plate 15 upwards and the release of the bolts 14, 14 'and their return to the bolt receptacles 6, 6'.

The reverse movement produces the return of the plate 15 in a sliding movement downwards with return of the latches 14, 14 'in the locking position on the Ricjel receptacles 6, 6'.

The plate 15 carrying the bolts 14, 14 'has, for its part, a Locking device in the closed position and is formed by a plate 24 which is hinged at 25 on the plate 15 is and in the extreme position is pressed to the right by a hairpin spring 26, which is with an arm on one on the Plate 15 attached stop 2 7 and supported with the other arm on a stop 28 firmly connected to the plate 24, which penetrates into a cutout 29 of the plate 15.

The plate 24 serving for locking has a cutout 30, which in the closed position of the bolt 14, 14 'on the

§09817 / 0806

Guide nose 19 * fits. It can be seen that under these conditions the cutout pushing onto the guide nose 19 ' does not allow a straight upward movement of the plate 24. Since this plate 24 is firmly connected to the plate 15, is located thus the arrangement is blocked in the closed position.

To release the plate 15, the cam 20 presses with its nose

22 '

21 on the attack side / of the plate 24 and presses it against the action of the hairpin spring 26 to the left and thus releases the cutout 30 with respect to the guide pin 19 '.

Under these conditions, the plate 24 is no longer in abutment on the guide nose 19 'and the plate 15 is made freed their locking position. As indicated above, the nose 21 of the cam 20 moves in its last movement in the Cutout 22 'of the plate 15 back and forth and generates the displacement movement this plate upwards, releasing the bolts 14, 14 'from the bolt receptacles 6, 6'.

Further design variants are based on the features described above executable. In particular, a version of the lock can be designed as a door catch. In this Case, the latches are beveled to press against the edge or the attack edge of the latch receptacles 6, 6 ', the Bolt can be returned upwards by a cam effect due to the pressure exerted on the attack edge of the striker 6, 6 'is exercised until the bolt in a known manner in returned to the higher position compared to the bolt mounts is. When the bolt arrives at the level of the openings or recesses 13 of the bolt receptacles, one of them will not Return spring shown returned to the closed position. This actuation corresponds to the usual actuation when slamming the door. In this case the actuators are adapted.

From the description and the drawing it can be seen that the bolt 14, 14 'supporting plate 15 has the role of a back and forth Moving mass plays, which can be moved vertically from top to bottom and is guided by guide lugs 19, 19 '. This mass carries the bars 14, 14 ', which come from one and the same mass and are part of the plate or reciprocating Mass 15 are »and represents the locking device that the bolt loops 6 inserted horizontally within the housing, 6 'blocked. This vertically displaceable part forms the essential point of the innovation according to the invention and differentiates different from previous devices in which the bolt can be moved horizontally.

It should also be emphasized that the slidable plate 15 carrying the bolts 14, 14 'is a reciprocating mass forms that can be moved vertically. The arrangement consisting of the plate 15 and the bars 14, 14 'shifts perpendicular and is supported by guide lugs penetrating into the column 17, 17 ' 19, 19 '. It follows from this that the vertically displaceable mass or plate 15 is complete during its movement is performed and enables the exact positioning of the bolt 14, 14 'in the bolt receptacles 6,6'. This vertical movement the bolt 14, 14 'causes a locking of the horizontal Riegolaufnähme 6,6 ', which in turn are enclosed within the housing forming the lock, and forms an essential innovation the invention. This vertical movement is in fact different from the usual horizontal sliding movement of the Bolt, which in the conventional locks in the bolt runner intervenes.
