Definitions

  • the invention relates to a locking / unlocking device for a swing latch of a working current door opener with a Locking lever, which locks or releases the swivel latch, a first locking lever, which the locking lever in the Locked position holds and with the help of an electromagnet a position releasing the locking lever is pivotable, and with a second safety lever, which is used to secure the impact the locking lever on the first locking lever attacks.
  • EP 0 279 878 A1 discloses a locking / unlocking device known with a surcharge. This protection against surcharges includes a second locking lever for locking a first locking lever, referred to as an inner anchor and another locking lever, referred to as the outer anchor.
  • the second safety or locking lever is in the pivot axis of the change or locking lever articulated and sufficient with a control edge and a detent, which with those referred to as inner and outer anchors
  • the locking levers work together via the locking lever out.
  • an electromagnet When an electromagnet is energized, the external anchor acting on the control edge first the locking lever triggers the lock and takes after a predefinable lead, the inner anchor for release the locking lever with.
  • the locking / unlocking device of DE 44 18 863 C1 has two safety levers, which are designed in opposite directions and interact with a nose at the change.
  • the first safety lever is as a mutual arm of the anchor an electromagnet and provided with a nose, the blocking in the blocking state on the opposite trained nose of change.
  • the second safety lever which swivels on the first Safety lever arranged and resilient against the change is biased, acts over a control edge with the Change together in such a way that he is aware of the change a deflection of the first locking lever into the open position is deflected like scissors.
  • the change with a nose can then between the stop on the second locking lever and pass the nose on the first safety lever.
  • On Impact on the housing leads to a deflection in the same direction, but not to a spread position, which is why at least one of the two locking levers the locking function maintains.
  • the invention has for its object to provide a locking / release device for a swing latch of a working electric strike, which has a particularly simple construction, allows efficient manufacture and assembly and ensures reliable and safe function even with a preload on the swing latch.
  • the object is achieved in that the second safety lever a mechanically decoupled, in his The focus is on lever of low mass, which from a locking the first locking lever Position by magnetic coupling to an anchor of the Electromagnets in a releasing the first safety lever Position is adjustable.
  • the invention is based on the first consideration Safety lever with a second safety lever, which as a mechanically decoupled and in its focus mounted lever is designed to secure.
  • the second locking lever On the mechanically completely decoupled, mass-balanced second locking lever with its proportionate low mass will vibrate or shake not broadcast.
  • the second locking lever is designed such that it is magnetically connected to an electromagnet detachable and pivotable and thus as an impact protection anchor is effective.
  • the second safety lever is expediently in the field of action of an electromagnet with a magnetizable Coil core, which preferably consists of a soft magnetic Material exists and a relatively large mass and one long acceleration path, arranged.
  • the first locking lever and the coil core are due a lack of mass balance on vibrations and The second remains, mechanical, to react to vibrations decoupled locking lever in its the first locking lever locking position so that the locking lever is not unlocked and the swivel latch is not released.
  • the second securing lever is provided with two symmetrically designed lever arms which are arranged tangentially on a swivel axis and which are oriented almost vertically and opposite to one another in an impact-securing blocking position and are preferably arranged in the region of an inside housing wall.
  • a first lever arm, oriented in the direction of the locking lever, is designed for positive and / or non-positive engagement on the first securing lever, while a second lever arm, which interacts magnetically with the coil core, is oriented upwards and is arranged in an impact-securing position adjacent to the inside housing wall.
  • the pivoting or rotating movement of the second locking lever limited to stick to the to avoid magnetized coil.
  • the path limitation is in achieved in a particularly simple manner in that the first lever arm at a defined pivoting or Rotation of the second locking lever around a horizontal one Swing axis strikes the inner housing.
  • the second locking lever is especially with the help of a spring a compression spring, which is on the housing side and on the first Lever arm is supported in its impact-securing Preloaded position and thereby prevents rotation to release the first locking lever and the locking lever.
  • a coil with a horizontally adjustable coil core of relatively large mass and long acceleration path between the first and second locking lever and above the locking lever as well the swivel trap arranged.
  • An active connection between the spool and the first safety lever is over a Coil pin reached, which is connected to the coil core and is adjustable with it and e.g. through a floor area the coil can be guided.
  • the coil core is magnetized against the force accelerated by a coil spring and moved into the coil. This will place the spool pin over the bottom of the spool moves out and engages with the first locking lever.
  • the first safety lever is in an appropriate design designed as a toggle and parallel to one to the pivot axis of the second locking lever and the Locking lever arranged pivot axis counterclockwise pivotable. He comes out of a locking lever locking and by the second locking lever secured position in an unlocked, the locking lever releasing position.
  • the interaction of the coil pin is particularly advantageous with the coil core, when pulling in the coil core the first safety lever is inserted into the coil Coil pin pressed into an unlocked position. simultaneously becomes second locking lever due to the magnetic Coupling to the coil core from its impact-securing Position pivoted.
  • the locking / unlocking device has a simple and space-saving construction. Associated with it are cost-saving manufacturing and assembly.
  • the mechanical fully unlocked and magnetic with the Coil core prevents adjustable second locking lever unlocking in the event of shocks or vibrations and also ensures reliable function with a preload.
  • Fig. 1 shows a partially sectioned view Working current door opener with a swing latch 2, one Locking lever 3, a first locking lever 6 and one second locking lever 10 and a coil set 4 with a coil or a coil bobbin 19 and one horizontally displaceable coil core 5, which as an anchor acts on the second locking lever 10.
  • the locking lever 3 is in the locking position shown in FIG. 1 on the swivel latch 2 and prevents its adjustment to open a door (not shown).

  • the pivoting movement is done by a spool pin 9 causes which in a bottom area of the coil 19 out and fixed to the coil core 5.
  • the coil core 5 is designed as an armature of the coil 19 and made of a soft magnetic material. With current flow the coil core 5 is magnetized by the coil 19 and drawn into the coil 9. The Coil pin 9 and the second locking lever 10 moved.
  • the first locking lever 6 is that shown in FIG. 1 Locked position by a compression spring 15, which is on the housing side and is supported on a second lever arm 8, preloaded.
  • the arrangement of the coil 19 with coil core is advantageous 5 between the first locking lever 6, the near a housing wall 24 on the striking plate side is arranged, and the second locking lever 10, which almost touches an inside Housing wall 25 adjoins.
  • Fig. 1 illustrates the symmetrical design and mass balanced Storage of the second locking lever 10, the can only be coupled magnetically to the coil core 5.
  • Fig. 2 shows the path limitation of the second locking lever 10 over the first lever arm 11. This strikes one Predeterminable rotary movement on the inside housing wall 25 and thereby decouples the second lever arm 12 from Coil core 5. Sticking the second locking lever 10 on Coil core 5 is thus avoided.
  • Both lever arms 11, 12 of the second securing lever 10 are for positive and non-positive engagement on the first lever arm 7 of the first locking lever 6 or on the coil core 5.
  • the impact-securing latching or reaching behind takes place in the area of an end face area of the first lever arm 7 of the first securing lever 6.
