Definitions

  • the invention relates to a self-locking panic lock with a spring-loaded cross latch, a slide-controlled bolt, a slide which can be moved in the longitudinal direction of the lock by means of a key actuation and a spring-loaded control part which locks the slide when the bolt is closed, and with a follower which has a panic lever actuating the slide.
  • a self-locking panic lock has become known, the slide of which can be moved by motor or mechanically.
  • a control part is provided with which the slide can be held in its upper position, which releases the cross latch, when the bolt is closed.
  • a lever called a follower is also connected to the one-piece lever follower, by means of which the slide and thus the bolt can be actuated and the door can be opened from the inside (panic function).
  • DE 37 36 592 C2 shows a tubular frame lock with a split nut.
  • DE 35 21 213 A1 also describes a split nut for a latch panic lock, in particular for tubular frame doors.
  • the object of the invention is to develop a self-locking panic lock of the type described above in such a way that a switchover function is provided, that is to say that bolt actuation via the handle is only possible from the inside or from the inside and outside. This is to be made possible in particular by advantageous structural features in the case of narrow locks, that is to say in so-called tubular frame locks.
  • the switching technology according to the invention should also be able to be used in self-locking panic locks which are provided with a device for delayed closure of the bolt.
  • the locking of an interchangeable part in its respective end position enables a simple construction of the operating mechanism, i.e. the interchangeable part does not have to be held in its respective position by components constantly acting on the interchangeable part. Since the interchangeable part only has to be moved within the lock housing for the coupling or decoupling process by a relatively small amount, there is the advantage that the unlocking of the door (dead bolt lock) and switching, i.e. the connection of two nut halves via the interchangeable part can be done with a single key movement.
  • a switch lever and a switch lever are mounted on the lock plate, which can be acted upon by key actuation (lock cylinder bit), the switch part being moved by means of the switch lever so that the nut halves are coupled and the switch part is moved by the switch lever that the coupling of the nut halves is released.
  • the switch-off lever is designed as a two-armed lever.
  • Both the on lever and the off lever are actuated by means of the lock cylinder bit; they act alternately on a switching cam arranged on the interchangeable part (claim 5).
  • an intermediate lever is arranged in the area of the follower nut, which is rotatably mounted on the lock plate and can be pivoted by a switching cam arranged on the interchangeable part (claim 6).
  • This intermediate lever is pivoted and actuated by the lock cylinder bit when the switch lever is actuated in turn a switch lever pivotally mounted on the handle follower, which couples the nut halves to one another.
  • the interchangeable part in its respective end position is advantageously locked by switching wedges which are positively guided on the one hand in a recess of the interchangeable part and on the other hand on guide cams of the lock plate (claim 7), two switching wedges spaced by a spring being arranged in the recess of the interchangeable part (claim 8 ).
  • the switch-on lever or switch-off lever skip "the switching wedges with their wedge surfaces, the guide cams arranged on the lock plate and thus fix the interchangeable part in the respective position relative to the lock plate.
  • the operation of the slide can be in the sense Bolt inference "and the actuation of the switch-on lever displacing the interchangeable part take place with a single key movement. It has proven to be particularly advantageous here to have the stop of the switch-on lever actuated by the lock cylinder bit included in the rotation curve of the lock cylinder bit so that at a predetermined position of the lock cylinder bit, which is fixed by a limiting cam of the locking cylinder contour, both the slide and the switch lever are supported in their upper position by the locking cylinder bit and thus locked in.
  • This key position surprisingly gives the advantage of a so-called Permanent open function ", ie the function of self-locking is canceled, which means that when the door is closed, the bolt is not excluded. This function can be particularly advantageous if material is removed by the Door is to be transported without the need to press a button.
  • the aforementioned features are characterized by claim 10.
  • the invention is basically applicable to all mortise locks; it is characterized by a simple structure and particularly advantageous use in narrow locks with limited space and in particular in those self-locking panic locks in which a delayed locking lock when closing the door is possible by means of a corresponding slide lock by means of a control latch and an additional control part.
  • the panic lock generally designated 1
  • the essential components of which are a lock plate 2, a face plate 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-off lever 15.
  • the bolt 6 is pre-closed, i.e. the slide 5 is in its lower position.
  • the cylinder bit 18 moving on the locking cylinder contour 4 has moved from its basic position 18 ′ against a stop 29 of the bolt 5.
  • a stop edge 25 of the slider 5 bears against a pin 20 of a cross drop shaft 19 of the cross latch 7.
  • the door is closed; the cross latch 7 is locked against inference.
  • the cross latch 7 is also unable to push back the control part 8 via a bolt extension 24 of the control part 8 which bears against the cross latch 7.
  • the slide 5 which slides in corresponding guides (not designated in any more detail) also locks the bolt 6 in its lower position via a mandrel 28 of the bolt 6.
  • the interchangeable part 12 is also in its lower position.
  • the door can only be opened via the follower 9 and the panic levers 11, 11 '- by means of which the slide 5 can be moved.
  • a hook-like extension 23 arranged in the upper region of the slider 5 grips a holding cam 22 on the control part 8, so that the slider 5 - seen in the image plane - is prevented from moving downwards.
  • the pin 20 on the cross shaft 19 is in a position opposite the slot 21 on the slide 5.
  • a return spring 30 of the slide 5 is now tensioned.
  • the interchangeable part 12 is in its lower position.
  • the door can now be opened by pulling it open or pushing it on without pushing the trigger, the cross latch 7 being pushed into the lock housing.
  • the control part 8 is also inserted and releases the hook-like extension 23 of the slider 5 relative to the holding cam 22 on the control part 8 (so that the slider 5 could be pulled downward in the plane of the image due to the pretension of the spring 30); at the same time, however, the pin 20 on the cross shaft 19 moves into the slot 21 of the slide 5, so that the slide 5 can only be moved slightly downward in the image plane by the play between pin 20 and slot 21; this results in the bolt 6 being extended by approximately 2 mm, which generally corresponds to the door air and thus does not have a disruptive effect.
  • the cross latch 7 with the pin 20 is first inserted into the slot 21 of the slide 5 when the door is closed and hold the slide 5 in position. Only after the door has been completely closed, ie when the cross latch 7 is directly opposite the corresponding opening in the striking plate, which is not shown, and can move into the opening of the striking plate, is the slide 5 released and, as a result of its downward movement, can extend the bolt 6. This causes a delayed extension of the rain 6 and prevents damage to the striking plate.
  • the cylinder bit 18 has been moved further in the image plane by approximately a further 30 ° to the right, starting from the position shown in FIG. 3.
  • the switch lever 14, which is rotatable about a pivot axis 38 has been pivoted and has shifted the change part 12 upward in the image plane via a switch cam 32.
  • the switch-off lever 15 has been pivoted slightly about its pivot axis 39 in a clockwise direction.
  • the result of lifting the interchangeable part 12 is that a switch cam 33 of the interchangeable part 12 runs against a corresponding edge of an intermediate lever 13 and the intermediate lever 13 pivots about the axis 41 connected to the lock plate.
  • the intermediate lever 13 itself pivots against a switch lever 10 which can be pivoted about the axis 43 arranged on the trigger nut 9 and which locks the two nut halves together. In this situation, the bolt 6 can be operated from both sides of the door using the respective handle.
  • switching wedges 16 are provided in a recess 34 in the interchangeable part 12 by a spring 36, which correspond to guide cams 35 which are firmly connected to the lock plate.
  • the recess 34 in the interchangeable part 12 can be covered by a cover surface 37 of a cover plate 17.
  • recesses 44 are also provided, which allow a sufficient displacement of the axis 41 of the connecting piece 13 within this recess.
