Definitions

  • the invention relates to a lock with a lock case, a latch and a rotatably mounted in the lock case, divided into two nut halves pusher, of which one half of the nut from one side of the lock and the other half of the nut from the other side of the lock is operable, each Nut half has a different from the circular shape receptacle for each one pusher axis and one of the nut halves, namely the inner nut is coupled to a nut engaging on the case center portion, and each nut half facing the other half of the nut central end face and a lock facing the outer face facing.
  • detachable locks not only in the one but are provided in both directions fittings with a handle, so that the castle, in particular its follower, can be operated from both directions.
  • These locks can be used for escape doors and have different panic functions. These panic functions control the functionality of the handle on the outside of the door. In the direction of escape, the door, even with vortexem bolt, always be committed by operating the handle.
  • the panic functions can be switched on and off by the nut center part can either be driven by only one half of the nut, namely the inner nut, or by both nut halves. If the lock is adjusted so that it can only be operated from the inside, then the outer nut is disconnected from the middle of the nut, so that no access from the outside is possible. About the inner nut but in case of panic the latch and the bolt can be withdrawn. To achieve this, the two nut halves are driven with separate square pins.
  • the invention is therefore based on the object to provide a lock, which still has a simple structure, but which is safer against manipulation from the outside.
  • the essence of the invention is to prevent by the support that the outer pusher axis can not be driven from the outside into the inner nut.
  • the support is in the way of the pusher axis and blocks it.
  • the support is connected to the outer pusher axis such that it can not be pushed further into the outer pusher nut.
  • the support is supported on the lock case or components in the lock case, e.g. on the inner nut.
  • the cross section of the axial support projects radially into the cross section of the inner half of the nut deviating from the circular shape and thereby blocks the insertion path for the outer pusher axis into the inner nut.
  • the support rests against the central end side of one or the other half of the nut.
  • the support is thus in the region of the nut middle part, ie between the two nut halves, and is located, for example, on the front side of the one and / or other nut half, ie the inner nut or the outer nut.
  • the central end face is the end face assigned to the other half of the nut. Since the support is not an attachment, it can not be detected from the outside.
  • the support is integral part of the lock and arranged in the lock case and thus not visible from the outside.
  • the support as a disc, in particular circular disc, formed whose outer contour is at least partially larger than the clear, deviating from the circular cross-section, and the inner contour is at least partially smaller than the deviating from the circular cross-section.
  • the support has the same or a smaller thickness than the nut center part.
  • the support when received by the nut center portion, may be disposed together with the nut center portion between the two nut halves without increasing the spacing of the two nut halves.
  • not only the external square drive but also the internal square drive is blocked, which has the advantage that the lock can be used as a left and right lock when the panic function from left to right switchable and the case is reversible.
  • Another variant provides that the support is coaxial with the pusher axis and rotatably mounted. The support forces are transmitted evenly to the other half of the nut to be protected, which in turn is supported by the lock cover.
  • the support bears against the outer end side of the outer nut opposite the inner nut or on the outer side of the lock cover.
  • the shell nut does not have to be opened or no components of the lock need to be changed.
  • the support is connected to the outer pusher associated outer pusher axis, in particular integrally formed therewith. So it must be replaced only the conventional pusher axis to block a driving this pusher axis. The support then rests on the outside of the lock cover.
  • the support is designed as a thickening of the pusher axis.
  • the thickening prevents further driving the pusher axis in the pusher half.
  • the support may also be formed as a transverse pin.
  • a high resistance is achieved in that the support is made of metal and hardened.
  • the dimension, in particular the thickness of the support remain so small that they can still be accommodated in the lock case when needed.
  • a lock which is designed as a mortise lock and in which the lock cover is removed and for the invention unimportant components have been removed.
  • the lock 10 has a latch 12 which can be retracted into the lock case 14 by rotating a pusher shaft 16 by means of a pusher (not shown) and driving a pusher nut 18 into the open position.
  • a nut center part 20 is coupled, which acts via a finger 22 on a latch tail 24 of the case 12 and this displaced in the lock case 14.
  • the follower 18 is divided into an outer nut half, the outer nut 26, and an inner nut half, the inner nut 28, two.
  • the lock 10 is installed in the door such that the outer nut 26 faces the outside of the room and the inner nut 28 faces the interior of the room, which can also be recognized by the trap 12.
  • the outer nut 26 or the inner nut 28 or both nut halves 26 and 28 can be connected to the nut central part 20, so that the lock 10 can be used as a conventional, operable from both sides lock 10 or as a panic lock, wherein the lock 10 also still as left and right lock 10 can be installed in a door leaf.
  • the case 12 is formed as a reversible case 12.
  • each nut half 26 and 28 is associated with its own pusher axis 16, so that the nut halves 26 and 28 can be driven independently of each other.
  • the one inner pusher axis 16 in this case has a centering pin 30 which is rotatably mounted in a pin receptacle 32 on the outer pusher axis 16.
  • the pusher axes 16 have a deviating from the circular cross-section, namely a square cross-section, and the two nut halves 26 and 28 are configured with correspondingly shaped receptacles 34 and 36.
  • a support 40 designed as a circular disk 38 can be seen, which lies between the nut halves 26 and 28 and is received by a circular opening 42 in the nut center part 20.
  • the thickness of the circular disc 38 is less than the thickness of the nut central portion 20.
  • the circular disc 38 has a central opening 44 through which the centering pin 30 engages.
  • the diameter or the outer contour of the circular disc 38 is dimensioned such that the circular disc 38 rests on the middle end face of the nut half 26 or 28 directed towards the middle of the lock.
  • the support 40 or circular disc 38 prevents the outer pusher axis 16 of the outer nut 26 in the inner nut 28th can be driven in the direction of the arrow 46, because although the centering pin 30 can pass through the circular disc 38 and the circular disc 38 but otherwise supported on the end face 48 of the inner half nut 28 and the path or the receptacle 35 of the inner nut 28 is blocked.
  • FIGS. 2 and 3 show a further embodiment of the invention, in which the outer pusher axis 16 of the outer nut 26 still has a thickening 50, which also acts as a support 40.
  • This thickening 50 is dimensioned so that it rests on the outer end face 52 of the outer nut 26 and on the outside of the lock cover 54.
  • This outer pusher axis 16 is in FIG. 3 shown in perspective view.
  • Both the circular disk 38 and the thickening 50 designed as supports 40 are shown as preferred embodiments with a circular cross-section. It is important that at least a portion of the support 40 extends beyond the cross section of the receptacle 36 radially, so that the receptacle 40 can be supported on at least one of the nut halves 26 and 28.
