The locking part 21 is by means of the open housing side bent retaining webs 37 held on the housing Io and the opened housing side is through the in the area of the Locking part 21 locked under the same lying lock cover.

The locking part 21 has laterally recesses 21a with which it is removed from the retaining webs after a certain displacement 37 can be removed.

The housing Io is on the opposite of the closure body 11 End area graduated in the housing thickness (height) on a certain housing longitudinal area - the side wall height of the Caseback lob has been decreased.

The full case thickness is in the range of the gradation 38 convex arc-shaped (part-circular).

This housing design is particularly advantageous in the case of the lock arrangement on glass door leaves, since it results in a lower one Housing length, which fits into a recess of the glass wing, has been achieved. This is where the graduated housing area lies on the glass wing and the full housing area partially fits into the recess of the glass wing. In the case of glass leaves A maximum glass cut-out depth of approximately l62 mm can be achieved in terms of production technology, so that the length of the housing encompassing the glass recess smaller than this must be. Since a larger recess would destroy the glass wing, the housing must be in the max. The top of the case 34 is also graduated in accordance with the housing gradation 38.

The puncture of the lock according to the invention is as follows:

If the closure body 11 is in the Pig. I shown closed but not locked position, there is a locking hook 27 behind the stop 16 and the actuation

lever 29 against both stops 3o, so that the closure body 11 through the driver 15 into the housing Io into the open position can be moved. The driver presses against the stop as it rotates in the direction of the arrow "A" 25 of the plate 14 and moves it with the locking member 18 and the closure body 11 in the direction of the driver plate 17-die Hook parts 27 can move freely between stop 16 and actuating lever 29. For closing the closure body 11, the driver 15 is rotated in the direction of the arrow "B" (see Pig.l) and first presses against the actuating surface 28 of the locking member 18 which engages behind the stop 16, this locking member 18 pivots outwards about the pin 13, so that the hook part 27 lies above the stop 16. The driver 15 now moves into the recess 26 and moves the locking and removable plate 14 with locking elements 18 and locking body 11 to the outside as the rotation continues. When the closed position is reached, the driver 15 moves out of the recess 26 and the locking member 18 can pivot about the point 13 towards the center of the housing and is locked in front of the stop 16 (see Fig. 3) · The closed position is now secured and the handle can can be moved without damage and without opening effect. To open the locking position, the driver 15 presses first against the actuating surface 28, the locking member 18 lifts and grips to move the bolt or the latch 11 into the opening 26, so that the raised locking member 18 is displaced over the stop 16 in the direction of the plate 17 will. The latch 11 is now unlocked, but is still in the closed position and can now by turning the Driver 15 or fully opened by the pusher. The driver 15 would be rotated further in the direction of the arrow "A" press again against the stop 15 and the plate 14 with the trap 11 move back.
