Definitions

  • the invention relates to an electric door opener with a coil set, which acts on a resiliently biased inner and outer anchor, and with a change in engagement with the inner anchor for locking a door opener latch.
  • a generic electric strike is known from DE-A 3 405 441.
  • the swivel latch is locked in the closed position by a rotatable locking body, the axis of rotation of which runs parallel to the swivel latch axis.
  • the locking body which can also be called a change, is in engagement with an electromagnetically actuated inner and outer anchor.
  • the invention has for its object to provide an electric door opener of the type mentioned, which is better secured against short-term opening due to impact.
  • the invention has the advantage that the inner anchor and the change are automatically locked together due to the resilient bias, so that the inner anchor is prevented from cracking open even when impacted. Unlocking takes place via the coil set if the inner anchor is released properly and with authorization. If, for example, the coil set is energized in an operating current door opener, the securing bolt of the inner anchor is released and the inner anchor is also disengaged from the change by the coil set after release.
  • a preferred embodiment of the invention is that there is a locking lever mounted in a pivot axis, the free end of which is provided with a nose which is in releasable engagement with a corresponding latching edge on the inner anchor, that the locking lever has a control edge which in the manner is in engagement with a control lever which can be actuated by the coil set, that when the control lever moves along the control edge, the locking lever is deflected to release the inner armature.
  • the advantage of this embodiment is that the locking of the inner anchor is realized with a very small number of individual parts and that a space-saving arrangement is possible.
  • a particularly simple further development consists in the fact that the outer anchor serves as a control lever and that the outer anchor is provided with a predetermined clearance in relation to the inner anchor for pre-actuation of the locking lever. This measure makes the formation of a separate control lever unnecessary.
  • the clearance of the outer anchor is preferably obtained in that the outer anchor and the inner anchor are connected to one another via a driver which has a corresponding play.
  • the locking lever may be mounted on the pivot axis of the change.
  • the locking edge of the inner anchor consists of a sheet metal part provided with an elongated hole and screwed onto the inner anchor.
  • An adjustment is made by moving the sheet metal part along the elongated hole.
  • the sheet metal part is provided with a tongue which overlaps the free end of the locking lever for guiding the locking lever. This measure ensures safe guidance of the locking lever, which prevents the free end of the locking lever with the locking edge from being deflected transversely to the pivoting movement and in this way coming out of engagement with the locking lug in an uncontrolled manner.
  • the bias of the locking lever in the direction of the latching lug of the inner anchor is preferably achieved in that a compression spring is arranged between the locking lever and a housing wall of the door opener.
  • the inner anchor can be held in its pivoting direction at a predetermined distance from the free end of the change with the aid of a spacer supported on the housing: this measure eliminates shock transmission in the longitudinal direction of the change to the inner anchor.
  • Fig. 1 illustrates an electric door opener in side view, in which a housing cover 2 is largely removed, so that the view of the individual parts is released.
  • the outer armature 17 has a predetermined clearance with respect to the inner armature 18, so that when the coil set 3 is energized, the outer armature is first attracted alone and that the inner armature 18 is not carried along by the outer armature 17 until after passing through the free space. In the example shown here, this is realized by a hook-shaped driver 20 at the free end of the outer anchor 17, which engages under the inner anchor 18 at its free end.
  • the outer anchor 17 is loaded by an anchor spring 4.
  • the inner anchor 18 is provided with a detent 21 for engagement with a detent edge 22 of a change 9, which serves to lock or release a door opener latch 10. If the inner anchor 18 is pivoted outwards by the outer anchor 17, the latching edge 22 is disengaged from the latching nose 21 and the change 9 is released. In this state, the door opener latch 10 can be pivoted about its latch axis 13 by pushing the change 9 away from the nose 23 on the door opener latch 10 against the force of a change spring 12. The change 9 pivots about a change axis 24. On the other hand, if the latching edge 22 is engaged on the inner anchor 18, the change 9 lies in the pivoting range of the nose 23 and prevents the door opener latch 10 from opening. This is brought into the starting position by a latch spring 14 after each movement in which, in the example shown here, it ends flush with a striking plate 16.
  • Fig. 1 illustrates that state of the electric door opener in which the change 9 is engaged on the inner anchor 18.
  • the outer anchor 17 is locked by a locking lever 7.
  • the lock is released via the coil set 3, as will be described in detail below. As long as the coil set 3 is not energized, the lock on the switch 9 cannot be released.
  • the locking lever 7 is formed in the example shown as a flat sheet metal part which is pivotally arranged on the change axis 24. Furthermore, the locking lever 7 is biased by a compression spring 25, which is supported on a housing wall 8. The pivoting movement of the locking lever 7 runs perpendicular to the longitudinal axis of the inner anchor 18. In the locked state, a nose 6 on the locking lever 7 engages behind a corresponding nose or edge 26 on the inner anchor 18, which is shown in FIG. 1 in a purely schematic manner. If the locking lever 7 is pivoted outwards, it releases the inner anchor 18.
  • the locking lever 7 is released via a control edge 5 which is in engagement with the outer anchor 17.
  • FIG. 1 illustrates that the inner anchor 18 is held at a predetermined distance from the end face of the change 9 via a spacer 27, which is supported on the door opener housing.
  • FIG. 2 further illustrates the way in which the inner anchor can be locked.
  • the nose or edge 26 which interacts with the nose 6 of the locking lever 7 is formed on a sheet metal tab 29 which is attached to the inner anchor 18 (not shown here).
  • the tab 29 is provided with an opening 30 and an elongated hole 31 for attachment and adjustment on the inner anchor. With the help of a bolt (not shown), the tab 29 is first pivotally arranged on the inner anchor, with a deflection for adjustment purposes being possible via the elongated hole 31. For final attachment, the tab 29 is screwed into the elongated hole 31.
  • the tab 29 has a tongue 28 which engages over the locking lever 7 in such a way that it receives precise guidance between the tongue 28 and the inner anchor located underneath and prevents the locking lever from escaping perpendicular to the plane of the drawing.
  • the inner anchor is now released. It can therefore be disengaged from the change by the driver 20. For reasons of clarity, these parts are not shown in FIG. 2.
