A partially sectioned view of the locking device shown in Figure 3 including a slide rail.

As shown in FIGS. 1 to 4, the locking device 1 according to an embodiment of the present invention, a housing 2 and a cover 3. As shown in FIG. 4, the housing 2 is in a slide rail 4 arranged, in which a slider, not shown is slidably arranged. The locking device 1 comprises further a first plunger 5, which two at one end of a housing 2 provided holding claws 16 with the slide (not shown) can engage and disengage. The holding claws 16 point a retaining lug 17 and a first pair of rollers 18 and a second Pair of rollers 19 to the frictional resistance in contact with the first Keep plunger 5 or the slider as low as possible.

The locking device 1 further comprises a second plunger 6, which is firmly connected to a connecting part 7. The connecting part 7 has a bore 23 in which the first plunger 5 is partially received is. Furthermore, a spring 14 is provided, which between a annular counter bearing 15 of the first plunger 5 and one on the connecting part 7 arranged adjusting nut 12 is arranged. The adjusting nut 12 can be adjusted via a thread 24, whereby the Biasing force of the spring 14 can be adjusted. The adjusting nut 12 is by means of a snap ring 13 against unscrewing Connection part 7 secured.

As can be seen in particular from FIG. 3, there is a on the second plunger 6 pin-shaped locking element 8 which is perpendicular to the middle Axis 0-0 of the second plunger 6 is arranged. Next is in the area this locking element 8, a recess 9 is formed in the housing 2. How 3, the recess 9 has two Sloping slopes 10, so that the recess 9 has a V-shaped section Has shape. Here, the size of the opening of the recess 9 slightly smaller than the length of the locking element 8. This ensures that the locking element 8 in a certain position to the recess 9 is retained by the housing 2 and not in the recess can be arranged and rotated at a certain angle Position of the locking element 8 this is included in the recess can be.

In order to allow easy rotation of the second plunger 6, is on Tappet 6 a lever 11 arranged outside the housing 2, which can be easily operated by hand. To turn the lever too far To prevent 11 is on the slide rail 4 for each direction of rotation a stop 25 is provided (see FIG. 4).

Furthermore, an elongated hole 22 is provided in the connecting part 7, in which a locking pin 21 firmly connected to the first plunger 5 is arranged. The locking pin 21 is inside the elongated hole 22 (see FIG. 3) in the direction of the axis 0-0. This allows the first plunger 5 perform a certain stroke in the direction of axis 0-0. However, the locking pin 21 prevents rotation of the first Tappet 5 around axis 0-0.

Below is the operation of the locking device according to the invention described for a door leaf. When a door is opened is, the slider (not shown) in the direction of the fixed in the Slide rail 4 arranged locking device 1 moves. In the open end position of the door leaf, the slide is directly adjacent to the locking device 1 is arranged. Here, the slider points directly adjacent to the locking device two protruding lugs on, behind which can grip the holding lugs 17 of the holding claws 16.

In the initial state of the locking device shown in FIGS. 2 and 4 the locking element 8 is arranged in the recess 9, i.e. the second plunger 6 is rotated such that the two of the second plunger 6 protruding ends of the locking element 8 is added in the recess 9 are.

If a determination of a door leaf is now desired, the Lever 11, as shown in Figure 4, from the starting position to a position 11 'transferred. As a result, the second plunger 6 rotates about the axis 0-0 and the locking element 8 assumes the position 8 'shown in FIG. 4. Here, the locking element 8 on the two bevels 10 of the Recess 9 pushed out of the recess 9 until it, as in the Figures 3 and 4 shown, is transverse to the recess 9. Thus through Rotate the lever 11 of the second plunger 6 around the fixed to the second Tappet 6 connected connecting part 7 axially in the direction of the first tappet emotional. As a result, the spring 14 is compressed somewhat in the axial direction, so that the exerted on the annular counter bearing 15 Preload increased. As a result, the first plunger 5 becomes axially in the direction the holding claws 16 moves. Thus comes the front, conical Tip of the first plunger 5 with the first rollers 18 of the holding claws 16 in contact. Since the holding claws 16 are rotatable at pivot points D are stored, they rotate about the pivot points D and move the retaining tabs 17 perpendicular to the axis 0-0 to the outside. As a result, the retaining lugs 17 engage behind those provided on the slider Projections (not shown) so that the slider through the locking device 1 is held firmly and not in the axial direction away from the Locking device 1 can move. Here, the holding claws 16 rotated around the pivot point D until it stops with a stop 20 Housing 2 come into contact. Thus the door wing is over the slider and held a door closer in the open position.

If the determination of the door leaf is now to be solved, the Lever 11 turned back from the position shown in Figure 1 until the locking element 8 via the bevels 10 back into the recess 9 returns. Here, the spring 14 acts via the adjusting nut 12 and the connecting part 7 on the second plunger 6, so that this in the axial direction is biased away from the first plunger 5. This moves the locking element 8 automatically when turning the lever 11 into the recess 9 back. Thus, the spring 14 is relaxed again Condition so that a restoring force of the door closer via the Slider acts on the retaining lugs 17, so that they are around the pivot point D turn back to its original position and the slide release. As a result, the door leaf is again over the door closer automatically closed.

Thus, according to the invention, a locking device for a door leaf provided, which is particularly operable by hand. However, it is also conceivable to move the lever 11 by motor. Can continue through the Adjusting nut 12, the spring force of the spring 14 can be adjusted so that in coordination with the closing force of the door closer Manageability with minimization of one to be applied via the lever 11 Force can be achieved. Since the locking device is a compact unit, door retrofits are also easy possible, which have a slider.
