Abstract

The slide (5) controlling the bolt (6) is moved in the lengthwise direction by a key, and is locked by the spring-loaded component (8) with the bolt in the retracted position. A divided core (9) has a lever (11) actuating the slide. The lock ward has a changeover component (12) slid in either direction by the key with the bolt retracted, and by which the halves of the core are coupled and uncoupled. In each end position the component is locked in position in relation to the lock plate. There can be an engagement lever (14) pivoting on the plate and moved by the key into the position coupling the core halves together.

Description

The invention relates to a self-locking panic lock with a spring-loaded Cross latch, a slide-controlled bolt, one in the longitudinal direction the lock can be moved using a key Slider and one locking the slider when the bolt is closed spring-loaded control part and with a follower, which has a panic lever actuating the slide, the lock set up has a sliding interchangeable part over which the nut halves are optionally connectable and end-connectable, and that the interchangeable part in its respective end position opposite the lock plate is locked.

DE 36 36 237 A1 describes an actuatable by means of a lock bit Panic lock of the type mentioned above with a divided Lock nut, on the inside and outside of the door a rotating handle is arranged. Starting from the Panic function, in which only the turning handle on the inside of the door is effective, a switchover can take place, whereby by means of Lock bit actuated slide and one connected to the lock nut Clutch lever the nut halves can be coupled, so that the rotating handle located on the outside of the door is effective. When the door is opened, the coupling becomes automatic canceled.

DE 37 36 592 A1 describes a key-operated tubular frame lock with anti-panic function, with the relevant for the anti-panic function Components according to a predeterminable escape direction in the castle can be applied. For switching to the panic function a split nut is provided, with adaptation to the predeterminable Direction of escape different switching discs use Find.

From DE A 39 38 655 a self-locking panic lock is known become, whose slide moves motor or mechanical can be. Except for the lock bolt and the cross latch A latch part is provided with which the slide with the bolt locked in its upper, releasing the cross latch Position can be held. With the one-piece follower is further connected to a lever called a follower, via which the Slider and thus the bolt operated and the door from the inside can be opened (panic function). The lock set up of the above Lock does not provide any components with which it is possible the door can also be opened from the outside by pressing the handle.

DE 35 21 213 A1 also describes a split nut Trap panic lock, especially for tubular frame doors.

The object of the invention is a self-locking panic lock to further develop the type mentioned at the beginning with reference to the switchover function. This is said to be due in particular to advantageous structural features narrow locks, i.e. in so-called tubular frame locks be made possible. The switching technology according to the invention should also be used in such self-locking panic locks can find which with a device for delayed advance of the bolt are provided.

The invention solves this problem by teaching according to claim 1. In particular the locking of an interchangeable part in its respective End position enables simple construction of the operating mechanism, i.e. the exchangeable part does not have to be constantly loaded by the exchangeable part Components are held in their respective positions. There the interchangeable part within the lock housing for the coupling process or decoupling process only by a relatively small amount must be moved, there is the advantage that the unlocking the door (dead bolt lock) and switching, i.e. connecting two nut halves over the interchangeable part, with a single key movement can be done.

When the interchangeable part is actuated, the switching wedges "skip" with their wedge surfaces each arranged on the lock plate Guide cams and thus place the interchangeable part in the respective Position opposite the lock plate.

Further features of the invention are characterized by the subclaims.

According to claim 2, the switching wedges receiving recess in Interchangeable part through a cover plate closing the recess covered, in particular the spring that spreads the switching wedges to secure their position

According to claims 3 and 4 are a lock lever on the lock plate and a switch lever mounted, which by key operation (Lock cylinder bit) can be acted upon, by means of the switch lever the interchangeable part is moved so that the nut halves are coupled and the change part is moved using the switch-off lever will be that the coupling of the nut halves is released.

In an embodiment of the invention, the switch-off lever has two arms Lever trained.

Both the on lever and the off lever are operated using the Lock cylinder bit actuated; they act alternately on you switching cams arranged on the interchangeable part.

On the lock cylinder and thus the switch lever or switch lever opposite side of the interchangeable part is in the area the follower arranged an intermediate lever, which is rotatable on Lock plate stored and arranged by one on the interchangeable part Switch cam is pivotable. This intermediate lever is activated of the switch lever pivoted through the lock cylinder bit and in turn actuates a pivotally mounted on the handle follower Switch lever that couples the nut halves together. When actuated the switch-off lever, i.e. in the event of a shift of the The intermediate lever disengages from the change lever, so that the two nut halves are decoupled.

As mentioned above, the actuation of the slide in the sense of "bolt back yoke" and the actuation of the switching lever shifting the change part with a single key movement. Doing it turned out to be particularly advantageous that the lock cylinder bit actuated stop of the switch lever in the rotation curve of the Lock cylinder must have a border that at a predetermined Position of the lock cylinder bit by a limiting cam the lock cylinder contour is fixed, both the slide and the Switch-on lever in its upper position through the lock cylinder bit supported and thus locked. With this key position results surprisingly, the advantage of a so-called "continuous open function", i.e. the self-locking function is canceled what means that when the door is closed the bolt is not excluded becomes. This function can be particularly advantageous if Material is to be transported through the door without having to press a button is required.

The invention is basically applicable to all mortise locks; it is characterized by a simple structure and in particular advantageous use in narrow locks with limited Space as well as in particular with such self-locking Panic locks, in which an appropriate slide lock by means of a control trap and an additional control part delayed locking lock when closing the door is possible.

1 shows the panic lock, generally designated 1, the essential components of a lock plate 2, a faceplate 3, a slide 5, a bolt 6, a cross latch 7, a control part 8, a follower 9, a change part 12, a switch lever 14 and a switch lever 15 are.

The following is the function of the self-locking panic lock described with reference to the other drawings.

In the illustration according to FIG. 2, the bolt 6 is locked, i.e. the Slider 5 is in its lower position. The one on the Locking cylinder contour 4 moving cylinder bit 18 has its Home position 18 'moves against a stop 29 of the slide 5. at the illustrated position of the slider 5 is a stop edge 25 the slide 5 on a pin 20 of a cross shaft 19 of the Cross trap 7. In this situation the door is closed; the cross trap 7 is locked against inference. As a result, the cross trap can 7 also not the control part 8 via a contact with the cross latch 7 Push back bolt extension 24 of the control part 8.

The one sliding in corresponding guides, not specified Slider 5 also locks the latch 6 in its lower position a mandrel 28 of the bolt 6. The interchangeable part 12 is also located in its lower position. The door can only be pressed 9 and the panic levers 11, 11 '- by means of which the slide 5 can be moved - be opened.

In Figure 3, the slide 5 is by means of the cylinder bit 18 over the Stop 29 has been moved up in the image plane; is there the bolt 6 in a known manner via a slot 26 in the slide 5th has been closed and has 45 with its slide edge Stop cam 40 of the interchangeable part 12 and thus the interchangeable part 12 in the image layer shifted to the right.

A hook-like extension arranged in the upper region of the slide 5 23 grips a holding cam 22 on the control part 8, so that the Slider 5 - seen in the image plane - prevented from moving downwards is. At the same time, the pin 20 is on the cross shaft 19 in a position opposite the slot 21 on the slide 5. A return spring 30 of the slide 5 is now cocked.

It can be seen that to actuate the slide 5, i.e. for inference the bolt 6 only a key rotation of about 160 ° in clockwise sense is required.

In the illustration according to Figure 3, the interchangeable part 12 is in its lower position. The door can now be opened or pushed open can be opened without trigger actuation, the cross latch 7 in the Lock housing is inserted. This will also be the case Control part 8 inserted and gives the hook-like extension 23 of the Slider 5 relative to the holding cam 22 on the control part 8 free (so that the slider 5 due to the bias of the spring 30 in the image plane could be pulled down); at the same time, however, the moves Pin 20 on the cross shaft 19 in the slot 21 of the slide 5, so that the slide 5 is only about the game between pin 20 and slot 21 can be moved slightly down in the image plane; this has an extension of the latch 6 of about 2 mm, which in general corresponds to the air in the door and therefore does not interfere.

Starting from the position of the cylinder beard 18 in Figure 3, the Key removed, i.e. the cylinder bit 18 is brought into position 18 ', when the door is closed, the cross latch 7 with the pin 20 first insert into slot 21 of slide 5 and slide 5 hold in position. Only after closing the door completely, i.e. if the cross latch 7 of the corresponding opening, not shown, in the The striking plate is directly opposite and in the opening of the striking plate can retract, the slide 5 is released and as a result extend the latch 6 in its downward movement. This is a delayed Extending the bolt 6 causes and damage to the Avoid striking plate.

According to Figure 4, the cylinder bit 18 - and that starting from the position according to Figure 3 - further in the image plane by about another 30 ° been moved to the right. Here, the one that is rotatable about a pivot axis 38 Switch lever 14 has been pivoted and has a switching cam 32 the interchangeable part 12 is shifted upwards in the image plane. At the same time, the switch-off lever 15 is about its pivot axis 39 in clockwise rotation has been pivoted slightly. The lifting of the interchangeable part 12 has the result that a switch cam 33 of Exchange part 12 against a corresponding edge of an intermediate lever 13 runs and the intermediate lever 13 around the connected to the lock plate Axis 41 pivots. The intermediate lever 13 itself pivots thereby against an axis 43 arranged on the follower 9 pivotable switch lever 10, which the two nut halves together locked. In this situation, the bolt 6 of both Door sides can be operated using the respective handle.

In order to hold the interchangeable part 12 in its position, are in a recess 34 in the interchangeable part 12 switching wedges 16 separated by a spring 36 provided with the guide nock firmly connected to the lock plate 35 correspond. The recess 34 in the interchangeable part 12 is through a cover surface 37 of a cover plate 17 can be covered. in the exchange part 12 and in the cover plate 17 recesses 44 are also provided, the sufficient displacement of the axis 41 of the intermediate lever Allow 13 within this recess.

In the key position according to FIG. 4 there is the peculiarity that (compare Figure 3) the cylinder bit 18 simultaneously an actuating arm 46 of the switch lever 14 and the stop 29 of the slide 5 is supported. If the key is left in this position, there is a so-called "Continuous opening function", i.e. the door can be opened or Open and close as often as you like without pushing the button be without the bolt 6 in the recess of the associated Strike plate retracts. There is therefore no bar exclusion. The one described above Key position is advantageously fixed in that in the area a limiting cam the rotation curve of the locking cylinder contour 4 42 is arranged, which a further rotation of the key in right-handed sense prevented.

With a key turn in the left-hand sense - starting from the figure 4 - the "continuous open" function is canceled; the toggle function remains however.

In the illustration according to FIG. 5 - starting from the position Figure 4 - the key has been operated in a counterclockwise direction; there the cylinder bit 18 pivots the switch-off lever 15 in a counterclockwise direction Senses, so that the switch-off lever 15 on a switch cam 32 on Interchangeable part 12 moves the interchangeable part 12 downward in the image plane, so that the switching wedges 16 are now substantially below the guide cam 35 are. The nut halves are thus decoupled. When closing the door - as described above - the through a spring 31 loaded cross latch 7 retract into the striking plate Lower the slide 5 release, so that the latch 6 is delayed in the striking plate can retract.

In FIG. 6, 27 are arranged in the control slot 26 of the slide 5 Designated rest stops; prevent these stop points 27 undesired pushing back of the slide 5 even when the Slider 5 is not completely in the corresponding recess of the Strike plate retracted, so it is not fully locked.
