Definitions

  • the invention relates to a door lock with a convertible latch and with a faceplate through which the latch passes, and with a latch shaft connected to the latch and guided in the lock housing, which is detachably coupled to a lever handle that can be actuated and controls the latch movement.
  • Door latches have a ramp that interacts with a striking plate on the stock side.
  • the arrangement of the run-on slope on the left or the right latch side must match the direction of closing of the door.
  • locks mortise locks
  • the latch can be adapted to the need for on-site, i.e. directly at the construction site, the closing direction of the door.
  • a construction is known in which the latch can be pulled out of the lock housing over the faceplate against the force of a spring at most with the aid of a tool and can be rotated through 180 ° about a cylindrical central axis with respect to the falling shaft. As soon as you let go of the trap, it jumps back and the change is complete.
  • Another embodiment has recesses in the size of the latch in the side walls of the lock housing in the area of the latch shaft directly after the faceplate. The latch can be pressed back into the interior of the lock housing and rotated through 180 ° in the area of the recesses around a central axis. After the change, the trap jumps back to the basic position.
  • the invention aims to simplify the construction of a door lock with an adjustable latch and the changeover itself. This is achieved according to the invention in that, as the articulated connection between the falling shank having two parallel legs and the retraction lever ending in the space between the legs, a driving pin which can be displaced between the legs in a transverse bore of the retraction lever and is under spring preload is provided for coupling into one of the two legs Recesses can be snapped into place. If the clutch is disengaged by pushing back the driving pin, there is no connection between the retraction lever and the drop shaft, so that the latch can be pulled out of the door lock together with the drop shaft. After inserting the latch with the shaft in the desired direction, the spring-loaded drive pin engages again and the change is complete.
  • the trap is also interchangeable. It can be color-matched to the lever handle set and selected, for example, in brass or chrome. The exclusion length can also be adapted to the circumstances by exchanging the trap. Finally, it is also possible to use a roller trap if necessary. It is expedient if the driving bolt can be pressed back against spring force through an actuating opening aligned with the bolt in a lock plate of the lock housing and can be disengaged from engagement with the falling shank. To move and remove the latch with the shaft from the lock housing, the driver pin is inserted through the actuation opening in the side wall, e.g. pushed back by means of a pin (screwdriver), whereupon the latch with the shaft can be removed, turned over and reinserted.
  • a pin screwdriver
  • the falling shank or the legs of the same have run-on bevels at their free ends for gripping under the front side of the optionally spherical driving pin and for pushing back and for latching into the recess of the falling shank. At this Training is no longer necessary to manually actuate the clutch when inserting the latch into the lock housing. From a design point of view, it is advantageous if the leg of a latch spring on the latch side is provided for spring biasing of the driving bolt. This gives the latch spring a double function.
  • FIG. 1 shows the latch area of a mortise lock in longitudinal section
  • Fig. 2 shows a cross section
  • FIG. 3 shows a section along the line III-III in FIG. 1
  • FIG. 4 shows a section through a partial area of FIG. 1 along the line IV-IV, but in one stage the latch is inserted shortly before the clutch engages.
  • a latch 4 with a shank 5 is slidably mounted in a lock housing, which includes a faceplate 1 and side lock plates 2, 3, a latch 4 with a shank 5 is slidably mounted.
  • the retraction lever 6 is operated on the one hand by a lever system 8 by a pusher.
  • the retraction lever 6 engages in the drop shaft 5 and transmits its rotary movement into a linear retraction movement of the latch 4.
  • a spring 9 surrounds the axle bolt 7 and pretensions the retracting lever 6 in the sense of extending the latch 4.
  • a disengageable coupling 10 which comprises a driving pin 11 which can be displaced in a transverse bore 12 (stepped bore) of the retraction lever 6 against spring force (leg 13 of the spring 9).
  • the driving pin 11 projects beyond the retraction lever 6 and, in its extension position limited by a collar 14 (FIG. 2), engages in a vertical elongated hole 15 in one leg of the drop shaft 5. If the retraction lever 6 is pivoted to the right (FIG. 1) by means of the pusher, the driving pin 11 describes a circular arc and, sliding in the elongated hole 15, takes the falling shaft 5 with the case 4 with it.
  • An opening 16 is provided in the lock plate 3 of the lock housing (FIG. 2), which is aligned with the driving pin 11 in the basic position according to FIG. 1. If the trap 4 is now to be changed, then the driving pin 11 is pushed back against the force of the spring 13 or 9 until the driving pin 11 disengages from the elongated hole 15 of the falling shaft 5.
  • the driving pin 11 is pushed back expediently by means of a screwdriver which is inevitably within reach when installing a mortise lock. As soon as the driving pin 11 is uncoupled from the drop shaft 5, the latter can be pulled out of the lock housing together with the latch 4 on the cuff side. After turning the case 4 with the shaft 5 is pushed back into the opening in the face plate 1 (Fig. 4).
  • the two legs of the drop shaft 5 are each provided on the end face with a ramp 17.
  • the drop shaft arm of the retraction lever 6 has a slot 18 in which the leg 13 of the spring 9 lies.
  • a latch spring which is arranged independently of the retraction lever 6 and acts on the latch shaft 5, can be provided for the latch ejection.
  • the driving pin 11 would have a separate spring. If, in this variant, the driving pin 11 is pushed in, that is to say uncoupled, the latch 4 with the shaft 5 automatically springs out of the lock housing under the action of a latch spring (automatic ejection).
  • the retraction lever can also be part of the lock nut and thus be directly connected to the handle.
  • the lock nut then has a projection which carries the clutch 10 which can be disengaged against spring force at its end analogously to the retraction lever 6. So that the trap, for example when slamming an open toe, simply backs away without moving the pusher (i.e. when the trap is activated in reverse), the driving pin 11 does not engage in an elongated hole 15, but in one Recess, which also extends in the direction of the trap, the length of the recess corresponding to the trap exclusion.
  • a deflecting surface for example a nose-like projection, can also be provided on the drop shaft 5, on which the driving pin 11 engages.
  • a freewheel can also be installed between the handle and a lock nut, so that the handle takes the nut with it, in the opposite direction the nut movement does not lead to a movement of the handle.
  • the driving pin can also be provided in the falling shank and — can be disengaged against spring force — engage in a recess in the retraction lever or in the nut or engage on a contact surface of the retracting lever or the nut.
