Definitions

  • the invention relates to a mortise lock with a bolt guided in the lock housing on a slide, wherein the slide, which can be displaced approximately parallel to the faceplate by means of a key bit or a lock cylinder locking lug, has a slot running approximately diagonally to the faceplate for the engagement of a pin arranged on the bolt.
  • DE 43 37 969 A1 shows a self-locking safety lock, in which the bolt is locked in the extended position against shifting by a tumbler in the gear element. At the same time, when the handle is actuated, the extended bolt can be both unlocked and retracted, in such a way that a device is present which locks the bolt in the retracted position.
  • DE 44 07 244 C1 discloses a method for operating a lock, in which two conditions must prevail to exclude the rain, namely the door concerned must be closed and the door latch must also be operated. This ensures that the door latch excludes when the door in question is open. At the same time, the bolt is only held in this position in the closed state if the door has actually been opened.
  • EP 0 092 630 A1 solves the problem of designing a lock of a known type in such a way that it can also be brought into an open position with a key without actuating the handle.
  • the drive means formed as a force transmission means between the bolt and the drive rod so that there is an ineffective force transmission only in the open position of the rain; the force transmission is only effective when the rain is moved in the opening direction.
  • the object of the invention is to make use of the displacement path of the slide required for locking the bolt and to simplify the locking of the bolt.
  • the invention solves this problem with the teaching of claim 1.
  • the slide is biased against the force of a restoring spring when the bolt is closed and held in its biased position.
  • this can be done by turning the key a quarter turn.
  • the bolt is returned from its fully closed position to the fully closed position.
  • the locking mechanism for the bolt lock is to a certain extent armed ".
  • the beard of a locking cylinder can grasp the free end of a release lever which, when acted on in the opposite direction, now releases the lock, so that the slide is suddenly withdrawn from its associated spring and triggers the latch lock. It can be seen that in order to trigger the bolt lock, strictly speaking, it does not even require a one-turn locking, but only the unlocking of a lock, whereby less than a quarter turn of the key is required.
  • the slide in the region of its upper free end has a spring cam for a spring; with the same effect, this spring could also be arranged in the area of the lower end of the slide.
  • the locking lever is L-shaped, a catch for a catch cam of the slide being arranged at the upper free end of the longer L-leg.
  • Claims 5 and 6 characterize advantageous features of the release lever.
  • the mortise lock 1 essentially has a lock plate 2 which is delimited by a faceplate 3 on the striking plate side.
  • the main components are the slide 4, the bolt 5, the locking lever 6 and the release lever 7 (see Figures 3 to 5).
  • a slit 14 is provided in the slide 4, which extends approximately diagonally at an angle of approximately 45 ° to the faceplate 3.
  • the slot 14 has locking points 16 and 17 at the ends, between which additional locking points 18 are arranged on the upper longitudinal side 32 of the slot 14.
  • These additional locking points 18 each have a sliding surface 19 and a locking surface 20, which correspond to a pin 15 of the rain 5 shown in FIG.
  • mortise lock 1 The action of mortise lock 1 is as follows:
  • FIG. 1 the bolt 5 is shown with complete bolt closure.
  • the locking cylinder locking nose 31 bears against the slide 30 of the slide 4.
  • the slider 4 is moved upwards in the image plane, the slider 4 with its elongated holes 9 and 11 being guided on the pin 8 fastened to the lock plate or on the socket 10 fastened to the lock plate.
  • a spring 36 is attached to a spring cam 27 (FIG. 3), which is attached to the bush 10 at the other end.
  • the spring 36 is thus tensioned, the displacement path being dimensioned such that the upper free end of the slide 4, at the end of the displacement path, engages with a catch cam 37 in a catch 26 of the locking lever 6.
  • the locking cam 37 slides in an elongated hole 38 of the lock plate 2.
  • the tension spring 39 is mounted on the one hand on a pin connected to the lock plate and on the other hand on a spring cam 28 of the release lever 7.
  • the locking cylinder locking lug 31 runs against the lower free end of the release lever 7 and moves it upward in the image plane.
  • the release lever 7 slides with its elongated hole 22 in a pin 23 connected to the lock plate.
  • the edge 40 of the release lever 7 runs against the lower edge 41 of the short leg 24 of the locking lever 6 and pivots it about the pin 42 , so that the detent 26 releases the detent cam 37 of the slider 4 and the slider 4 suddenly flies downward in the image plane.
  • the locking lever 6 is held in its clockwise rotating position by a spring 43 arranged on the bush 10.
  • the pin 15 of the rain 5 slides in an elongated hole 13 of the lock plate 2;
  • the release lever 7 has an elongated hole 12 which is larger in accordance with the displacement of the elongated hole 22 in the eye 21 of the release lever 7.
  • the nut 34 or the trap 35 are only indicated, their function can be designed arbitrarily with reference to the invention.
