Definitions

  • the invention relates to a lock which can be actuated from the outside of a door or the like.
  • a significant safety-related deficiency in such locks is that after the forcible removal of the outside locking device, the lock can be operated with an auxiliary tool to bring it into the open position. With the removal of the locking device, the opening of the lock receiving the coupling rod is free, so that the auxiliary tool - for example a screwdriver - can engage in it.
  • the object of the invention is therefore based on the object to make a lock of the type in question in a technically simple manner against unauthorized opening in such a way that after removal of the outside locking device the lock-side opening for the coupling rod is no longer accessible.
  • This sleeve also serves to accommodate the channel locking jaw which can be displaced in the transverse slot. It has the shape of a wall segment. If the coupling rod is pushed in, this wall segment with the remaining cross section of the bushing at the level of the transverse slot is complemented into a circular shape. If the coupling rod leaves the channel, the wall segment or the channel locking jaw moves inwards and accordingly projects into the channel in such a way that attaching a tool does not allow the channel locking jaw to be displaced into a release position.
  • the spring acting on the channel locking jaw is also structurally very simple and economical.
  • an elastic spring ring encompassing the bush and the cheek is selected, which engages around the cheek at the height of the transverse slot.
  • the jaw constantly strives to want to close the channel. So that the coupling rod can still be used from the outside of the door after mounting the sleeve and locking jaw, the channel locking jaw has on the inside of the door side facing flank a run-up slope. An auxiliary tool inserted from the inside of the door pushes against this before the coupling rod is inserted, along with an outward displacement of the channel locking jaw. The coupling rod can then pass through the channel by pushing back the auxiliary tool.
  • the locking rod then acts like a clamping body on the locking rod, so that a clamping fit of the sleeve with locking jaw is created on the coupling rod.
  • Large tearing forces acting on the bush can be absorbed without damage by the bush having a plate-shaped flange on its end face facing the inside of the door. This is preferably made of the same material as the bush. If the cross slot in the bush completely penetrates the channel and the base of the cross slot ends beyond the channel wall, the locking jaw cannot be moved from the outside of the door even with very pointed or knife-like burglary tools.
  • a door denoted by the number 1 carries on its inside 2 a box-like lock 3 of conventional construction.
  • the latter contains a lock 4 which can be locked and closed. From the inside of the door, it can be actuated by means of a locking cylinder, not shown, which is accommodated in a front housing projection 5 of the lock 3.
  • the lock set-up is covered by a lock cover 6 which is adjacent to the inside 2 of the door 1 and which is held on the lock housing 8 by means of screws 7.
  • the lock cover 6 supports a rotatable driver 9, which is operatively connected to the lock mechanism with a pin 10 projecting into the lock.
  • the rotatably mounted driver 9 contains an opening 11 which has a rectangular cross section and runs in the axial direction.
  • the same is adapted to that of a coupling rod 12 which connects the lock 3 to a locking device 14 arranged on the outside of the door 13.
  • a coupling rod 12 which connects the lock 3 to a locking device 14 arranged on the outside of the door 13.
  • it can be one which can be actuated after insertion of a magnetically coded key card (not shown).
  • an external turning handle 15 assigned to the locking device 14 is used, which after inserting the correct key card in coupling position comes to a nut 16 of the locking device 14. This allows the bolt 4 to be moved back and forth.
  • the nut 16 is a carrier of a square mandrel 17.
  • a slot 18 machined from the front side thereof receives the end 19 of the coupling rod 12 on the outside of the door.
  • a cross pin 20, which passes through both the square mandrel 17 and the end 19 of the coupling rod 12, both are connected to form a unit.
  • the end 21 of the coupling rod 12 lying on the inside of the door passes through a channel 22 and enters the opening 11 of the rotatably mounted driver 9 in a form-fitting manner.
  • the channel 22 upstream of the driver 9 is located in a bushing 24, the end face of which faces the inside of the door 2 has a plate-shaped flange 25 which is received by a recess 26 on the inside of the door.
  • a bore 27 adjoins the recess 26, into which the bushing 24 projects.
  • a channel locking jaw 28 is assigned to the channel 22.
  • the latter is spring-loaded in the closing direction and is supported on the wide surface of the coupling rod 12 facing it.
  • the channel locking jaw 28 has the shape of a wall segment which lies in a transverse slot 29 of the sleeve 24. This cross slot 29 extends through the full channel cross section and extends to the corresponding channel wall 22 '.
  • the sleeve is provided with an annular groove 30 which continues into a partial annular groove 31 of the wall segment or the channel locking jaw 28.
  • the locking jaw 28 and the sleeve 24 are surrounded by an elastic spring ring 32.
  • this consists of rubber and is placed on with tension such that that the locking jaw 28 strives to move in the direction of the channel wall 22 '. If the coupling rod 12 is not in the channel 22, the wall segment lies with its tendon-like surface F against the channel wall 22 'due to the spring load.
  • the locking jaw 28 can also be held in the release position before the initial assembly, which is pushed out of the coupling rod end from the channel 22 when the coupling rod 12 is inserted from the outside of the door.
  • the filler piece has a shorter length than the sleeve 24 in order to achieve a threading effect.
  • the coupling rod 12 leaves the opening 23 of the driver 9 and also the channel 22 as soon as the channel locking jaw 28 is no longer supported on the coupling rod 12, the locking jaw 28 becomes the spring jaw 32 shifted in the radial inward direction until it is supported with its tendon-like surface F on the channel wall 22 '. It is then no longer possible to reach through the channel 22 by means of a burglary tool, a screwdriver or the like in order to be able to turn the driver 9.
  • the cross slot could also be cut so deep that the locking jaw 28 is supported in its locked position beyond the channel wall 22 '.
  • the displacement path of the locking jaw 28 is then greater than the thickness of the channel 22.
