Definitions

  • the locking element for automatically locking the locking unit can be actuated (e.g. by a release magnet) in such a way that the locking element releases the lock chain (into the lowered locking position) so that the latch bolt is automatically transferred into the extended locking position.
  • locking unit means in particular an additional lock of an espagnolette lock or also a central lock of an espagnolette lock.
  • Additional locks on the one hand and the handle and key-operated central lock are connected in a known manner via connecting rods, so that in the course of locking, not only the central bolt arranged in the central lock, for example, but also the locking elements (especially latchbolts) arranged in the additional locks are excluded.
  • the invention consequently relates to a self-locking locking unit or a self-locking lock, which in practice is also referred to as an automatic lock.
  • Characteristic of such an automatic lock is the fact that the locking elements, e.g. B. the latch bolt of the additional lock, automatically enters the locking position when the door is closed.

  • the lock latch is a conventional lock latch that is spring-loaded and, when unloaded, assumes an extended position.
  • the lock latch consequently runs with its inclined surface against the frame when the door is closed and is thereby pushed towards its retracted position.
  • the latch of the secondary lock is coupled via a pivot lever to a transmission element in such a way that when the handle of the main lock is actuated and the drive rod moves, the latch is moved into the retracted position against the force of the spring element.
  • the lever is released, the lock latch automatically returns to the extended position thanks to the force of the spring element.
  • the position of the leaf in the area of the secondary lock is to be fixed in such a way that the hook bolt is free and without friction in the course of the self-actuated locking triggered when the leaf is swiveled shut can retract the associated opening of the frame-side locking plate.
  • a partial retraction of the lock latch is sufficient to ensure the desired, defined position of the sash.

  • the locking element is held in the unlocked position by this securing element.
  • the locking element is intended by the in the retracted position Lock latch can be held in the unlocked position.
  • the triggering of the automatic locking should be controlled by a double safety device, namely once that the locking element located in the unlocked position is held in the unlocked position by the locking element located in the safety position and once by the fact that the locking element located in the unlocked position is held in the unlocked position by the in the lock latch located in the retracted position is held in the unlocked position.
  • a double safety device Starting from the open position of the leaf or the door or the like, a two-stage sequence control for triggering the automatic locking is implemented in the operation of the lock, which is intended to increase the reliability and security of the locking and effectively prevent incorrect operation.
  • This lock which is primarily designed as a central lock of a multi-point lock, works with a conventional spring-loaded latch.

  • the swivel hook bolt 25 is secured against being pushed back by means of a securing lever 33.
  • the latch bolt 3 is in the in Figure 5a , 5b
  • the fully extended locking position shown is also secured against being pushed back, via the securing element 34.
  • a comparative consideration of the Fig. 4 and 5a shows that this securing element 34 according to Figure 5a has reached the locked position secured against being pushed back.
  • the latch bolt 3 is not only secured against being pushed back in this fully extended locking position, but already in the position shown in FIG Fig. 4 limit position shown or from the in Fig. 4 shown limit position. As a result, a two-stage or double back pressure protection is implemented.
  • the functional positions shown that the swivel bolt is only transferred into the pivoted locking position when the latch bolt the in Fig. 4 has reached the partially extended (backpressure secured) limit position shown.
  • this limit position cantilever the latch bolt 3 by a limit M2 over the lock housing or the lock faceplate, which is greater than the unlocking dimension M1 and smaller than the locking dimension M3.
  • the limit dimension M2 is approximately 13 mm, while the unlocking dimension M1 is approximately 10 mm and the locking dimension M3 is approximately 20 mm.
  • the lock is unlocked starting from Figure 5a , 5b z. B. by actuating the pusher or lock cylinder or by a motor drive in which the drive rod and thus also the lock chain 4 connected to it is raised.
  • This unlocked position is not shown separately in the figures, but it is shown in FIG Figure 5b It can be seen that the lock chain 4 has a projection in the area of the actuating arm 35 which, in the course of lifting the lock chain 4, pivots the lever 33 in a clockwise direction and thus lifts it.
