Definitions

  • the present invention relates to a door opener for a door having the features of the preamble of claim 1 and a door operating system having the features of the preamble of claim 18.
  • a door opener is known in which a strike plate of a door is associated with an adjustable door opener trap. In a closed position, a spring-biased door latch snaps into the door latch of the striker, so that the door is locked, that can only be opened again by a manual or motorized release of the door bolt. In this door opener is now provided that the door latch can be released electromagnetically. This release is achieved by pivoting the door opener latch into an open release position so that the door latch is no longer blocked by the door opener latch.
  • a disadvantage of this construction is that no conventional strike plate can be used, but this must have the swiveling door opener trap, Such a construction is relatively expensive and retrofitting is not possible without replacing the strike plate. Furthermore, relatively high forces must be overcome in the opening release. Finally, the equipment of the strike plate with a door opener trap basically represents a mechanical weakening of the strike plate, which leads to a considerable reduction of burglary safety.
  • the invention is therefore based on the problem of specifying a door opener, which is optimized in terms of structure and functionality. Furthermore, a door operating system should be optimized in terms of structure and functionality,
  • the basic idea of the present invention is that the drive unit of the door opener is designed such that the opening release of the door bolt against its spring bias by the drive unit is disengaged from the strike plate adjustable, the strike plate itself remains unaffected by this adjustment. This makes a structural transformation of the strike plate unnecessary, but standard strike plates of any strength can be used. A simple retrofitting of doors is thus possible without replacing the strike plate.
  • the proposed door opener thus causes the opening release exactly the adjustment, which can be effected in known door locks by the manual operation of a door handle.
  • An advantage of the proposed solution but the fact that the motor opening release completely manages without the operation of a door handle or a similar complex mechanism.
  • only the door latch of the door lock, and otherwise no further element of the door lock is adjusted in the motor opening release.
  • the drive unit is associated with the strike plate, preferably namely arranged behind the strike plate in a cutout, and pushes the door latch out of the strike plate.
  • the drive unit can be easily integrated into the door frame, it is arranged so that it is not visible from the outside and therefore does not disturb the appearance of the door.
  • the door bolt is pushed out of the strike plate by means of an actuating element designed as a pivoting lever.
  • the pivoting lever itself is preferably driven by means of an eccentric arrangement and moved between an opening release position in which the door latch is pushed out of the striking plate, and a closed position in which the actuating element is disengaged from the door latch and engages the door latch in the strike plate.
  • the pivot lever is preferably pivotally mounted at one end and engages at the other end with the door latch to its adjustment.
  • the eccentric intervenes to move the pivot lever in one place Its two ends, this arrangement is particularly compact and allows for the forces occurring a simple design.
  • an eccentric is particularly advantageous insofar as this is sufficient when using a rotary electric motor for driving the eccentric a single drive direction.
  • the adjustment of the actuating element between opening release position and closed position is carried out automatically by advancing the eccentric in the same direction as before, a reversal of direction is therefore not necessary.
  • the strike plate has a recess for receiving the door bolt in a closing plate plane.
  • the actuating element is designed as a pivot lever and that the pivot axis of the pivot lever is aligned substantially parallel to the strike plate plane.
  • the claims 14 to 16 relate to preferred embodiments that are advantageous for very specific space requirements. With these preferred embodiments can be achieved in a simple manner that the main extension direction of the door opener is parallel to the strike plate plane (claim 17). This is particularly advantageous if in the direction perpendicular to the strike plate level only little space for the realization of the door opener is present.
  • Another solution according to the invention is a door operating system with a door opener and a door drive.
  • a door operating system with a door opener and a door drive.
  • Such a combination allows a complete remote operation of a door, namely both the ⁇ réellesfieigabe and the subsequent motorized opening of the door.
  • the motorized closing and locking of the door is possible.
  • a common control is provided which tunes the movement of door opener and door drive to each other.
  • the door drive is on the EP 05 013 184.6
  • Fig. 1 shows a door opener for a door 1 for motor release of the door 1, the door 1 has a door frame 2 and a hinged about a pivot axis hinged thereto door leaf 3. Furthermore, the door 1 has a lock assembly 4 with a lock 5 on the one hand and a striking plate 6 on the other. In general, the lock 5 is associated with the door leaf 3 and the striking plate 6 with the door frame 2.
  • the lock 5 has an adjustable spring-loaded door latch 7. This snaps when closing the door 1 by its spring bias in the strike plate 6 a.
  • the door leaf 3 can thus not be easily pressed, but only an opening release of the door bolt 7 is necessary.
  • the adjustment of the door bolt 7 is preferably aligned perpendicular to the pivot axis of the door panel 3.
  • the above opening release is preferably manually possible, for example by actuation of a well-known door handle.
  • a motorized opening release of the door bolt 7 by a door opener is provided here.
  • the door opener has for this purpose a drive unit 8, through which a motor release of the door bolt 7 from the strike plate 6 can be effected with the door 1 closed.
  • the drive unit 8 is configured in such a way that the door latch 7 can be displaced out of engagement with the striking plate 6 against the spring preload by the drive unit 8 for motorized opening release (FIG. 2).
  • the drive unit 8 is here and preferably (Fig. 1, 2) associated with the strike plate 6, namely behind the strike plate 6 in the door frame 2 and arranged extending through this in the wall behind it.
  • the drive unit 8 is designed so that the door latch 7 is pushed out of the strike plate 6 at the motor opening release, so that subsequently the door 1 can be opened by simply pressing or pulling the door leaf 3.
  • the drive unit 8 is associated with the door latch 7 and the door latch 7 is pulled out of the strike plate 6 during the motorized opening release.
  • the arrangement of the drive unit 8 in the door frame 2 is also advantageous in terms of safety, since this makes it difficult to engage from the outside.
  • the drive unit 8 has an actuating element 9 for adjusting the door bolt 7.
  • the actuating element 9 is for motorized opening release of a closed position in an opening release position in which the door latch 7 is out of engagement with the striking plate 6, movable. In this case, the actuating element 9 comes into engagement with the door latch 7 and displaces it out of engagement with the striking plate 6.
  • the actuating element 9 is designed here so that it adjusts the door latch 7 only in one direction, namely from the closed position to the opening release position.
  • the provision of the door bolt 7 is effected by the spring bias.
  • the actuating element 9 has an engagement element 10 for engagement with the door latch 7.

  • the engagement member 10 is further preferably arranged so that it engages with the door latch 7 at a direction of movement of the door bolt 7 substantially vertically aligned portion 11 of the door bolt 7. This ensures that the necessary force for adjusting the door bolt 7 is as low as possible.
  • the power transmission takes place so that directly opposite to the spring bias of the door bolt 7, the occurrence of shear forces is avoided. This is shown in FIG.
  • the adjustment of the door bolt 7 is shown in the form of an arrow.
  • the actuating element 9 is arranged so that it is arranged sunk in the closed position (Fig. 1) with respect to the striker plate 6. In the present case, therefore, it does not project beyond the striking plate 6. In contrast, in the opening release position (FIG. 2), the actuating element 9 extends out of the striking plate 6.
  • the actuating element 9 is designed as an eccentric.
  • the eccentric is arranged so that it comes to the motor opening release in direct engagement with the door latch 7 and pushes the door latch 7 from the strike plate 6. Subsequently, the eccentric is moved out of the adjustment of the door bolt 7, so that it can snap back into the strike plate 6.
  • actuating element 9 is configured separately from an eccentric 12 and is movable by means of the eccentric 12 between the opening release position and the closed position.
  • the return movement from the opening release position into the closed position can take place in a simple embodiment by a spring assigned to the actuating element 9 or else by the spring force of the door bolt 7.
