Definitions

  • the invention relates to a lock according to the preamble of claim 1.
  • Such a lock is both from CH 596 418 and from DE 1 746 397 known.
  • crank latch locks A rear arm of the crank is supported on the back of the cuff of the castle.
  • GB 300,027 describes a lock with a bolt which is H-shaped Has cross-section.
  • the object of the invention is based, a generic To improve the lock technically.
  • the trap carries a two-armed crank, the inner one Arm is supported at the rear on the assigned projection.
  • the lead now has a double function. On the one hand it serves to guide the trap and on the other hand to support the crank.
  • the lock can be used Use narrow cuffs because of the sliding surface which is the back arm when cranking is shifted towards the middle of the faceplate. safety-related it is convenient that the outer arm with of his side pointing away from the sloping slope Wall of a shaft forms, the opposite Wall is formed by the cuff, the Sloping traps in front of the shaft ends. It is therefore not possible as with DE-GM 1 746 397, by means of one inserted between striking plate and cuff Object, for example a plastic strip or Plastic card, the trap from its locked position push back. The increased safety value has been achieved with very little effort, by only design of the outer arm.
  • the cuff has two in the area of the trap opening the constriction protruding extensions.
  • a trouble-free function is achieved in that the inner arm is spring loaded supported on the cuff and against the Spring force can be swung into a rear escape space is. The inner arm then becomes in these pivoted if the trap is inserted or removed shall be. In the pivoted position of the interior Then this is poor beyond the projection and accordingly allows trouble-free insertion or Pulling out the trap.
  • the immersion opening extends over the front of the trap extends. With complete crank swivel grasps an angled end of the concerned Arm section in the area in front of the trap face.
  • the lock shown designed as a mortise lock according to the first embodiment has the reference number 1. Its lock case 2 is on a cuff 3 stated. The faceplate width a is in the embodiment 16 mm.
  • the lock case 2 includes one Castle floor 4 and a castle overhanging Castle ceiling 5.
  • a follower 6 stored in the upper area of the lock case 2 in the upper area of the lock case 2 is a follower 6 stored in the upper area of the lock case 2 .
  • the nut arm 7 engages on a projection 8 of a trap tail 9. This forms in Connection with a trap head 10 a trap F.
  • the trap head 10 Seen from the front of the trap is the trap head 10 approximately H-shaped. Is accordingly the trap recess 16 in the cuff 3 designed.
  • the trap head 10 forms a bevel on the front 17, which in the middle of an immersion opening 18 is interrupted. The latter extends to over the trap face.
  • the immersion section in question bears the reference number 19.
  • the immersion opening 18 serves to receive a two-armed crank 20. This has an outer arm 21 and an inner one Arm 22, which two arms 21, 22 in one point Angles are arranged to each other. The corresponding one acute angle is greater than 60 °.
  • crank 20 with its inner Arm 22 is supported in the region of the projection 31, it is possible, also a corresponding offset of the hinge pin 28 in the direction of the long side 10 '' while achieving favorable kinematic conditions. These can therefore correspond to a crank, such as it is possible with 20 mm wide gauntlets. As a support surface namely the dimension x is gained, which the projection of the projection 31 over the longitudinal edge corresponds to the recess 16.
  • the trap head 10 forms one for the inner arm 22 adjoining the immersion opening 18, rearward Evasion room 34.
  • the latter is chosen so large that the crank 20 can be pivoted counterclockwise is.
  • the trailing edge 34 'of the escape space 34 limits this pivoting movement against the force of the Leg spring 29. After swiveling lies the extreme tip of the inner arm 22 beyond the Apex of the convex projection 31 and thus allows pulling out the trap head, after previous Loosen the cross screw 13, see Fig. 6.
  • the outer arm 21 shapes with its from the trap slope 17 pioneering side a wall 35 of a shaft 36.
  • the opposite wall 37 is the Forend front formed.
  • the Fig. 11 that the trap slopes 17 before Shaft 36 ends.
  • the outer arm 21 is connected to the shaft wall section 40 adjoining arm section 41, which the latter with complete crank pivoting aligned on the outside with the bevel 17, see Fig. 8. This is made possible by the immersion opening 18 of the trap head 10. A terminal angled Hook 42 then engages in the immersion section 19 of the trap face.
  • the arm portion 41 forms one in the shaft 36 inward slope.
  • Fig. 8 can also be seen that when complete Crank pivoting on the joint supports 25, 26, 27 existing hook projections 39 behind the faceplate lie.
  • the hook projections 39 are formed by on the joint supports 25, 26, 27 throats 43. The latter is aligned with the open angle between the outer arm 21 and the inner arm 22 at occurred trap.
  • Fig. 10 it is illustrated that a profiled Plastic card 46 between a door 45 or the cuff 3 and the striking plate 44 is inserted.
  • the leading edge 46 'of the card thereby enters the slot 36 and accordingly cannot be effective on the sloping slope 17 become. Unauthorized opening in this way is included Prevents security. Even with larger cracked air the plastic card 46 is directed into the slot 36, because of the infeed slope formed by the arm portion 41.
  • the cuff 47 of a lock 1 ' has one design Trap recess 48, which is the cross section of a trap F 'is adjusted.
  • the latter has a trap head 49 with subsequent pin 50, which is coupling in dips a trap tail 51.
  • From the front edge 52 of the trap head 49 starts a trap slope 53, which the two trap long sides 54, 55 with each other combines.
  • the one opposite the trap slope 53 Trap long side 54 is therefore in the trap exclusion direction seen, trained longer than the opposite one Trap long side 55, see in particular Fig. 15.
  • From the trap head narrow sides are approximately V-shaped guide grooves 56 incorporated into which protruding projections 57 of the cuff 47 protrude.
  • a crank trap F assign, because of the trap-side constrictions and the projections interacting with them the long sides of the latch recesses.
