Definitions

  • the invention relates to a lock with one of an actuating arm of a follower against the restoring force of a latch spring by turning the handle nut retractable case, wherein a control arm of the nut is guided by two guided in the lock housing and acted upon by a compression spring away sliders in a central position, which he when turning the nut for displacing a drive rod in or out of a locking position with simultaneous displacement leaves one of the two slides.
  • Such a castle is from the DE 4118478 C2 or from the DE 29501645 U1 known.
  • the nut is held there by a spring element in a neutral center position.
  • a coupling slide is provided, on which an arm of a nut acts.
  • This coupling slide two associated with respect to the housing linearly displaceable slide. These are acted upon by a compression spring in the direction away from each other. If the nut is turned clockwise or counterclockwise, the coupling slide is displaced linearly. As a result, either the one or the other slide is displaced against the restoring force of the compression spring with.
  • the follower is always moved back from the compression spring after a rotational movement in the neutral center position.
  • the invention has for its object to design the aforementioned lock manufacturing technology simpler.
  • attack flanks are formed by each slide, between which lies the control arm. It is now the control arm itself that interacts with the sliders. A coupling slide is no longer required.
  • the two attack flanks are preferably formed by projections which are formed on the slides.
  • the projections can be integrally formed the slides material. This is preferably done by making the slides as castings. These may be plastic parts or metal parts.
  • the projections can protrude from webs. Preferably, the projections protrude transversely to the extension direction of the webs.
  • the webs may extend in the direction of displacement of the slide, so in the effective direction of the compression spring.
  • the webs can run parallel to each other. They are thus partially adjacent.
  • the slides can each form a pot-like depression.
  • the two slides are preferably biased compression spring between the two legs of a retaining clip.
  • the distance between the two slides is chosen so that the attack edges are spaced from each other.
  • the distance between the two attack flanks is chosen so that the control arm of the nut can intervene in the space between the two attack flanks. If the nut is rotated, the control arm is pivoted. His trajectory corresponds to a curved path. In each case the front in the direction of rotation flank of the control arm acts on one of the two attack surfaces.
  • linearly displaceable slide is in the direction of rotation of the back of the control arm.
  • This slide is entrained in the rotational displacement of the nut, wherein the compression spring, which is supported on the other slide, is tensioned.
  • This increases the distance between the two attack flanks, as the attack arm leaves the other attacking flank.
  • the trajectory of the attacking arm is located on a circular arc
  • the trajectory of the attack flank is on a straight line, so that the edge of the control arm slides on the attack flank.
  • the headband is held positively in the castle ceiling or the lock bottom. For this purpose, it can form projections which protrude into corresponding recesses of the castle ceiling or castle floor.
  • the two slides can be guided in guides of the castle floor or castle ceiling.
  • the slide can form projections which engage in elongated recesses of the castle ceiling or the castle floor.
  • the displacement direction of the slides is preferably directed parallel to the direction of displacement of the trap. This is space saving.
  • the two slides together with intermediate pressure spring and retaining bracket can be present as a structural unit. They are then inserted in the already mounted state in the lock housing. Since the distance of the attack flanks formed by the projections corresponds to the width of the control arm, this is kept rattling.
  • the castle has a castle floor and a castle ceiling. Both are spaced apart and consist of stamped and bent parts. Between Schlossêt and Schlossdecke there is the Schlosseinunde.
  • This lock has a latch 4. This has a latch tail with an end projection on which an actuating arm 1 attacks.
  • the trap extends through a portion 23 'of a window 23 of a drive rod 9, the back of a cuff 27 is guided.
  • the cuff 27 has a the plan view of the case head 4 'adapted window in which the case head 4' is guided.
  • the other arm of the leg spring 3 which forms a trap spring, is supported on a fixed to the housing. At this pin 28 and the actuating arm 1 is supported.
  • the actuating arm 1 is mounted on a nut 2.
  • This nut 2 has a square opening for the passage of a pusher mandrel. From the nut 2 protrude in a diametrical opposite transfer cams 18.
  • These driving cams 18 are each in driving recesses 19 which are associated with the actuating arm 1.
  • the width of the Mitéesaussparungen 19 is greater than the width of the driving cam 18. This allows the nut 2 rotate by a certain angle, without the operating arm is nadomit towed.
  • Join the driving cams 18 but against the wall of the driving recess 19 and the pusher 2 further example. Clockwise rotated so pivots the rotational movement of the pusher 2, the actuating arm 1, which engages the rear projection of the latch tail. Along with this pivotal movement of the actuating arm 1, the case 4 is withdrawn.
  • the nut 2 is a control arm 5 is formed.
  • This control arm 5 has the shape of a tooth of a gear.
  • the mutually away flanks of the control arm 5 are involute curved and are at attack edges 10,11.
  • the two attack flanks 10,11 are spaced from each other by the width of the control arm 5 and face each other.
  • the attack flanks 10, 11 are formed by projections 12,13.
  • Each projection 12, 13 belongs to a slide 7, 8 of a spring assembly.
  • the slides can be made of plastic or metal. They are preferably molded molded parts.
  • the slides 7, 8 each form a pot-like recess 16.
  • the two pot-like depressions 16 of two slides 7, 8 face each other and each store one end of a compression spring 6, with which the two slides 7, 8 are acted upon each other away.
  • the two slides 7, 8 are compressed by a U-shaped retaining clip 17.
  • the U-legs of the retaining clip 17 forms a contact surface for the side walls of the slide 7, 8.
  • the headband 17 is not shown with positive locking means connected to the lock housing.
  • each slide 7, 8 forms a web 14, which is the extension of a side wall of the cup-like depression 16.
  • Each of the two webs 14, 15 has a protruding transversely to the direction of displacement of the slider or to the extension direction of the compression spring 6 projection 12, 13.
  • the projections 12, 13 form the two attack flanks 10,11.
  • each of the two slides 7, 8 forms guide extensions 30. These protrude in the assembled state into guide slots of either the lock bottom or the lock cover, so that the two slides 7, 8 are linearly guided.
  • the two webs 14, 15 partially run side by side.
  • the protruding from the webs projections 12,13 extend partially over the web 14, 15 of the other slide 7, 8, so that the two flanks 10,11 in the direction of movement of the slide 7, 8 are opposite.
  • the nut 2 engages with a further driving arm which also rests with motion clearance in driving recesses, on a espagnolette 20.
  • This espagnolette arm 20 acts on a drive rod slide 29, which is positively coupled to the drive rod 9.
  • the drive rod 9 is of a coupling extension of the espagnolette 29, which engages in a coupling window of the drive rod 9, moved.
  • the drive rod 9 has an elongated window 23 through which the substantially rectangular plan 21 having a bar occurs.
  • the two opposite broad sides of the bolt head 21 ' form recesses 24. These broad side recesses 24 are grooves which are slightly removed from the end face of the bolt head 21'.
  • the bolt head 21 ' forms a step 26.
  • This stage which is located in the transition region to the bolt tail, has on its lower side a broadside projection which forms a locking cam 25.
  • the latch can be actuated by the drive nut 31 by a lock cylinder. For this purpose, levers not shown are provided.
  • the drive rod 9 is shown in the locked position.
  • the window 23 of the drive rod 9 has a sidecut, which are formed by two opposing blocking projections 22. These rectangular blocking projections form with a rectangular narrow side in each case a step 22 ', which extends transversely to the extension direction of the drive rod 9.
  • the two mutually aligned steps 22 'thus extend transversely to the displacement direction of the drive rod.
  • the two blocking projections 22 have end flanks 22 ", which have a distance from one another which is smaller than the width of the bolt head 21 ', but the distance between the two end flanks 22" is greater as the distance of the two bottoms of the broad side recesses 24, so that the blocking projections 22 can dive by upward movement of the drive rod 9 from the locking position shown in Figure 2 in the broad side recesses 24, as shown in Figure 5, in which the drive rod in a release position is relocated.
  • the window 23 continues in a fall passage window 23 ', in which the head 4' of the trap 4 rests.
  • the latch 21 is actuated by the drive nut 31, for example, by a lock cylinder. He can be extended by turning the drive nut 31 so far until the step 26 abuts the drive rod 9 and the cuff 27.
