Definitions

  • the invention relates to an emergency release of a door lock, in particular a shaft door of an elevator, by means of which the door lock can be transferred by means of an emergency release key from a locking position to a release position, wherein the emergency release has a driver arranged in a housing or is assigned to such a driver, which under transfer of the Door lock is actuated in its release position by the emergency release key, including the emergency release key is to be introduced for coupling to the driver in a housing opening.
  • the invention is therefore an object of the invention to provide a device that increases the protection against manipulation of the door lock, in particular their emergency release, by unauthorized persons.
  • an emergency release according to claim 1, wherein a closure element is provided which at least partially closes the housing opening in its closed position to prevent insertion of the associated emergency release key for coupling to an emergency release actuated driver, and in an open position Introduction of emergency release key allows. Further, a control member is provided which can be transferred by attack of the emergency release key in a control position, in which this indirectly or directly on the closure element acting transferred the closure element in its open position.
  • the closure element is in this case preferably designed such that it completely covers the housing opening for the introduction of the emergency release key to the interior of the housing and completely closes, more preferably at least substantially or completely gap-free.
  • the introduction of thin foreign objects, such as wires is thereby impossible.
  • the closure of the housing opening by the closure element can in particular also be at least substantially media-tight, so that penetration of pasty or liquid foreign substances such as adhesives, water, acids o. The like. Prevented, or these can not cause dysfunctional damage.
  • the control member may also be upstream of the closure element with respect to the introduction of the emergency release key into the housing.
  • the control element can first be actuated by means of the emergency unlocking key and the closure element can be transferred to its open position in order subsequently to couple the emergency unlocking key to the driver of the emergency release in order to transfer the door lock into its release position.
  • the emergency release is carried out such that the emergency release key here after actuation of the control member is not to be removed from the emergency release in general or the control member in particular to couple the key to the driver.
  • a coupling of the emergency unlocking key to the driver can take place in that, after actuation of the control member, it is pushed further into the housing opening.
  • the driver of the emergency release can be arranged for this purpose in relation to the insertion direction of the emergency release key in the housing behind the control member.
  • control member as a rotatably mounted control disc

  • the passage opening of the blocking device bearing can generally be arranged in the cross-sectional area of the housing opening, preferably congruent thereto.
  • the control member may also be designed as a displaceable organ, so that the closing element is transferred into its open position by its displacement by means of the emergency unlocking key. The point of attack of the emergency release key on the control member can thereby be arranged independently of the location of the driver of the emergency release.
  • control member in particular as training as a rotatably mounted control disc, mounted in a receiving this control organ bearing, which in turn is movable relative to the housing, in particular rotatably mounted.
  • control member bearing can be relative to the housing the emergency unlocking be movable, preferably such that the emergency release key can be brought to the driver of the emergency release for coupling.
  • the control member can act by means of a driver directly on the closure element, possibly also by means of a suitable coupling mechanism.
  • the passage opening of the control device for the emergency release key can be designed to receive the key accurately.
  • the receptacle can also be adapted to the outer circumference of the key in such a way that the receptacle of the control member rests against the outer circumference of the wrench fully circumferentially free of play and possibly also without a gap.
  • the key can in this case have a shaft of constant cross-section, for example in the form of a conventional triangular wrench with end-side receptacle for the driver of the emergency release.
  • the introduction of the emergency release key into the receptacle of the control member can be limited by the closure element acting as a stop.
  • the closure element can be designed as a latch member.
  • the closure element can be pivotally mounted, wherein the pivot axis of the closure element can be arranged eccentrically to the axis of rotation of the control member.

  • the control member and the closure element may be designed such that the control member can act independently of the direction of rotation of the emergency release key on the closure element to convert this into its open position.
  • one or more eccentrically arranged driver can be arranged, which can act in both directions of rotation of the control member about its axis of rotation on the closure element, wherein the point of engagement of the driver is arranged on the closure element each eccentric to its axis of rotation, so that this from its closed position in his Opening position can be transferred.
  • a return element acting on it may be provided, for example in the form of a return spring acting on the locking element.
  • a locking device which acts in its blocking position blocking the control member and / or the closure element. An actuation of the control member or a transfer of the closure element in its open position is thus prevented by the locking device.

  • the locking device can be unlocked by an external device which can be provided in the control cabinet of the respective machine or elevator or in a special operating room by a corresponding action of an instructed and authorized operator and, if necessary, be returned to its blocking position.
  • the locking device may in particular comprise an electromagnet whose armature serves directly as a blocking member or acts via a transmission mechanism or an extension on a locking member. The locking device can lock with energized electromagnet or electroless electromagnet.
  • the housing comprising the closure element is arranged as an additional housing on the door lock housing comprising the driver of the emergency release.
  • existing door lock housing can be retrofitted particularly easy to form the emergency release according to the invention.
  • the additional housing can in this case be attached to a door housing such that the two housing openings overlap one another, coaxial or congruent to each other, so that after actuation of the arranged in the additional housing control the emergency release key by linear displacement on the arranged in the door lock housing driver of the emergency release coupled is.
