Definitions

  • Such door locks are predominantly mortise locks, which bring about the locking between the door leaf and door frame after they have been used by corresponding locks, such as e.g. Cylinder locks have been operated.
  • Conventional door locks of the type mentioned have a latch operated by the door handle and a bolt which can be moved by the lock.
  • the latch and bolt are operated independently of each other.
  • the latch is only operated by the lever handle and the bolt only by the associated lock or key.
  • the conventional door locks have disadvantages. So it is desirable to lock not only via the bolt, but also via the latch.
  • the construction should be as simple and stable as possible.
  • the trap should be easy to change from left to right. After the latch has been locked, this locking should not be noticeable via the trigger pin, i.e. that the trigger mandrel should be able to be pressed down despite the latch being locked. A possible burglar cannot recognize the fact that the latch is locked, which hinders his work.
  • the door lock according to the invention is primarily characterized in that the latch is locked in the closed position of the bolt.
  • the bolt is connected to a locking mechanism for the trap.
  • the locking mechanism has a latch link that can be displaced by the bolt and has a locking element that is arranged in the locking position in the displacement path of the latch.
  • FIG. 1 is a schematic side view of a door lock according to the invention with the cover removed.
  • Fig. 2 is a section along the line II - II in Fig. 1 through a component of the door lock. Both figures contain only those parts that are essential for the description of the present invention and its operation.
  • the mortise lock shown has, as usual, a faceplate 1 and a lock case 2, the cover of the lock case 2 being removed.
  • the bolt 3 is slidably mounted in the direction of arrow 4. 5 with the recess for a cylinder lock is not shown here, the locking lug cooperates in a known manner with the bolt recesses 6, 7.
  • the locking recess 6 locks during the first rotation and the locking recess 7 during the second rotation of the key.
  • the latch 8 is displaceable against the force of the latch spring 9 in the lock case.
  • the latch 8 is connected to the nut 11 in a manner described in more detail below via the latch pin 10.
  • the trigger mandrel not shown here, when it is rotated in the direction 13 against the force of the nut spring 14 and against the force of the spring 9, the latch 8 is pushed back.
  • the trap pin and the spring 9 are supported on the trap pin bearing 15.
  • the nut 11 engages with its mandrel 16 on a stop of the latch guide 17.
  • the latch guide 17 has a cross section as shown in FIG. 2.
  • the latch guide is slidably arranged in an undercut 18 of the latch link 19.
  • the latch link 19 extends downward along the rear wall of the lock case in the direction of the bolt 3.
  • the latch link 19 has an extension 20, on the lower edge of which a slot 21 leading obliquely upward is provided.
  • a bolt 22 connected to the bolt lies within the slot 21.
  • the operation of the door lock described is as follows: When the cylinder lock 5 is actuated, the bolt is moved one tour to the left. The associated bolt 22 is also shifted to the left, so that the latch link 19 must dodge upwards. After the end of the first tour, the bolt assumes a position as shown in broken lines in FIG. 1 with 22 '. The stop edge 23 of the extension 20 of the latch link 19 sits on the bolt 22 '.
  • the latch guide 17 is also pushed up (or pulled) so that the mandrel 16 of the nut 11 disengages from the associated stop. This allows the nut 11 to be rotated without actuating the latch 8, which is blocked by the locking pin 24.
  • the latch guide 17 is essentially U-shaped and receives the latch pin 10 between its legs 26, 27.
  • One leg 26 is somewhat shorter than the other leg 27.
  • the stop for the mandrel 16 is formed by the shorter leg 26.
  • the longer version of the leg 27 has the purpose of ensuring the guiding of the trap pin even in the pushed-up bearing of the trap guide and ensuring the attack of the trap pin with its head 28 on the trap guide.
  • the changeover of the latch 8 from left to right is simply achieved in that the latch 8 is pulled outwards against the pull of the spring 9 or another spring not shown here, outside the face plate 1, rotated and then let back into the guide of the face plate 1 can be.
  • the mandrel 16 abuts on the snail 26 of the latch guide 17 and displaces the latch guide on the undercut 18 of the latch link 19 to the right.
  • the force is transferred via the head 28 to the latch pin 10, which pulls the latch 8 into the lock case.
  • the catch is moved outwards again by the spring 9.
