Definitions

  • the invention relates to a lock, in particular mortise lock, comprising a housing, a control mechanism, which cooperates with a serving for the displacement of at least one locking bolt lock push rod, and a case which can be designed as a reverse trap and which is held by a movable retention in the housing.
  • a lock push rod is provided as a connection between the mortise lock and the Sperrriegeln.
  • This lock push rod moves the lock bolts from a locked position to an unlocked position and vice versa. It is desirable that the lock push rod is held in the two predefined positions and can be moved out of these positions only by applying a certain predefined force. Furthermore, the lock push rod should not remain in an intermediate position between the two predefined positions.
  • the object of the invention is to provide a lock, which eliminates the disadvantages mentioned above, is simple and inexpensive to manufacture, and both the case against falling out, as well as the final push rod, as described above, in predefined Holds positions.
  • the displaceable retention is formed by a arranged in a recess in the housing leaf spring which cooperates with a free end with engagement surfaces of the case, whereby the case is secured against falling out in the lock, and that the leaf spring at least a first and a second receptacle for against the force of the leaf spring displaceable mounting an engagement surface of the lock push rod is formed, whereby the lock push rod is held in at least two predefined positions.
  • the housing has an externally accessible bore in the forend which extends to the recess in which the leaf spring is arranged, and that the leaf spring has a portion which projects into the bore and as Serving surface for a manipulation tool is used, such that the leaf spring against the spring force in a release position for the case can be brought.
  • the leaf spring for example by means of a screwdriver, can be brought into a release position for the case.
  • the first recess of the leaf spring is formed by a fold thereof, wherein an ascending side portion is arranged substantially perpendicular to the recess base and serves as an end stop for the engagement surface of the lock push rod and wherein the second side portion as a convex arc is arranged at an obtuse angle starting from Ausappelungsground and serves as a flexible brake when moving the lock push rod from the recess out.
  • the second side portion as a convex arc is arranged at an obtuse angle starting from Ausappelungsground and serves as a flexible brake when moving the lock push rod from the recess out.
  • the trained as a flexible brake recess causes the unlocked position is only taken when the force is sufficiently large, and that the lock push rod is moved back in each intermediate position with too little effort back into the locked position.
  • the second recess of the leaf spring is formed by a fold thereof, wherein an ascending side portion is arranged substantially perpendicular to the recess base and serves as an end stop for the engagement surface of the lock push rod and the second side portion as a concave arc in an obtuse angle is arranged starting from Ausappelungsground and serves as against the spring force displaceable side stop for the engagement surface of the lock push rod.

  • Fig. 2 a detail of a side view of the castle Fig. 1 in a position with unfolded nut flap;
  • Fig. 3 a detail of a side view of the castle Fig. 1 in a position with folded nut flap
  • Fig. 4 a detailed perspective view of the castle Fig. 1 in the field of containment for the trap;
  • Fig. 6 a sectional view of the castle Fig. 1 in the area of the leaf spring
  • Fig. 7 a view of a lock according to the invention in the unlocked position without lock push rod
  • Fig. 8 a plan view of a lock according to the invention in the locked position with lock push rod.
  • lock 1 has a nut 2 with a nut flap 4.
  • other controls such as a nut push rod 7, to control additional lock components ( Fig. 1 ).
  • the nut flap 4 is pivotally mounted on the nut 2 via a bearing 8 and is guided by means of the control pin 9 via the control link 11.
  • the nut flap 4 is displaced via the control pin 9 along the control link 11 radially inwards in the direction of the axis of rotation 12, until finally the nut flap 4 is completely folded in an end position and not in the radial direction extends the circumference of the nut 2 ( Fig. 3 ).
  • the lock push rod 27 in Fig. 1 Not shown.
  • the reverse case 3 is arranged in the housing 18 in a recess provided for this purpose and is secured in this by the leaf spring 19 against falling out.
  • the leaf spring 19 engages with its free end 20 in an engagement surface 21 of the case 3 and thus prevents unwanted falling out of the case 3 (FIG. Fig. 4 ).
  • the leaf spring 19 can be compressed against the spring force with a manipulation tool, for example with a screwdriver.
  • a manipulation tool for example with a screwdriver.
  • the leaf spring 19 is compressed, the free end 20 is no longer in contact with the engagement surface 21 of the case 3, whereby the case 3 can be removed.
  • the leaf spring 19 is designed as a combination spring and additionally fulfills the function of securing the latch 3 in two predefined positions.
  • the lock push rod 27 is moved by the lock mechanism via the lever pin 26 and serves to shift Sperrriegeln.
  • the two predefined positions correspond to a locked and unlocked position of the locking bolt.
  • recesses 22, 23 are arranged in the leaf spring 19.
  • the lock push rod 27 engages with an engagement surface 28 in the Recesses 22, 23 a ( Fig. 5 ).
  • the ascending side section 17 corresponds to the section 29, which serves as a contact surface for the manipulation tool.
  • the lock mechanism is operated to move the lock push rod 27 by means of the lever pin 26 in the unlocked position, the engagement surface 28 of the lock push rod 27 moves along the convex arc 16 of the recess 22 of the leaf spring 19.
  • the convex arc 16 acts as a brake , which moves the lock push rod 27 in the locked position with too little effort. If the force required is large enough to overcome the spring force of the leaf spring 19, the engagement surface 28 of the lock push rod 27 is moved into the recess 23.
  • the lock push rod 27 is now in the unlocked position.
  • the recess 23 has a substantially vertically rising side portion 30, which serves as an end stop for the lock push rod 27.
  • the second side portion is formed as a concave arc 31.
  • a transmission device for actuating the lock push rod 27 is provided.
  • the transmission device comprises a nut push rod 7, which is mounted by means of a nut spring 33 in the housing 18 such that it is displaceable in the longitudinal direction of the lock 1.
  • the nut push rod 7 has a recess extending in the longitudinal direction, wherein a toothing 34 is arranged at the bottom of the recess.
  • the nut 2 has a neck which has a smaller diameter than the maximum diameter of the nut 2. On the neck circumference, a forceps-shaped toothing 35 is arranged, which is in engagement with a toothing 34 'of the nut push rod 7.
  • a toothing 37 with a recess with two limit stops 34 or a corresponding toothing of Nussschubstange 7 is engaged, wherein the toothing 37 is disposed on a lever arm of a lever 36.
  • the lever 36 is mounted in a pivot point 38.
  • the lever 36 carries a lever pin 26, which engages with a recess of the lock push rod 27. Since the toothing 35 of the nut 2 is arranged near the axis of rotation, with it the nut push rod 7 can be moved only by a relatively small amount.
  • the lever arm with the lever pin 26 is therefore made longer than the lever arm with the teeth 37, so that the lock push rod 27 covers a correspondingly larger way than the nut push rod. 7
  • the nut 2 fulfills a double function in a lock 1 according to the invention.
  • the case 3 which is displaced upon rotation of the nut 2 by a nut flap 4 into the interior of the lock 1.
  • the nut 2 actuates the push rod 27 via the nut push rod 7 and the lever 36 and therefore brings the lock 1 either into a locked (when locked) Fig. 8 ) or an unlocked ( Fig. 7 ) Position.
  • the lock push rod 27 further has a driver 40, which engages in a control block 32 of a locking bolt 39.
  • a driver 40 engages in a control block 32 of a locking bolt 39.
  • the lock 1 according to the invention thus has the advantage of having the simplest possible construction, which ensures the cost-effective production, low susceptibility to failure and a low backset. In addition, it is possible to perform all lock functions - lock, unlock and open - by operating nut 2.
