Definitions

  • the invention relates to a door opener according to the features of the preamble of claim 1.
  • door openers are used to enable or block electrically remote-controlled doors for passage.
  • An essential criterion for such electric door openers is on the one hand the construction volume of the door opener and on the other hand the holding force to be realized with the door opener.
  • This door opener has a housing in which a door opener latch is pivotably mounted.
  • the door opener latch is blocked or released by a change, the change in turn interacting with an armature acted upon by a coil, and the armature in turn blocking or releasing the change.
  • a high holding force can be achieved through the interaction with latch, change, armature and coil, but the mechanics are complex and require a certain amount of space.
  • an electrically operated door opener which also has a door opener latch pivotably mounted in a door opener housing. This interacts with a movable locking lever and a change to release or block the door opener latch.
  • the locking lever is moved by an electric motor in order to switch the door opener latch between the release position and the blocking position.
  • the object of the present invention is to provide an electrically operated door opener which has a high holding force with a structurally simple structure.
  • the door opener according to the invention should enable a small construction volume and preferably have a low release force.
  • the invention relates to a door opener with a housing for installation in a movable door leaf or in a stationary door frame with a door opener latch which is movably mounted in the housing and an electrical coil, around the door opener latch by means of a locking mechanism, between a release position in which the door opener latch is movable and one Lock position in which movement of the door opener latch is blocked.
  • the locking mechanism comprises at least one gear part which is movably mounted in the housing and which is designed as an armature and / or as a change. It is essential that the electrical coil or a part of the electrical coil is arranged within a movable gear part of the locking mechanism and / or within the door opener latch.
  • the electrical coil can be made in one piece, i.e. be formed with a single continuous coil winding.
  • the electrical coil can also be constructed in several parts, i.e. have multiple separate coil windings or multiple taps of a single coil winding.
  • the electrical coil acts directly in the locked position between the door opener housing and a gear part of the locking mechanism, preferably the armature or the change. It can also be provided that the electrical coil acts between two gear parts of the locking mechanism, for example the armature and the change, or acts between a gear part of the locking mechanism and the door opener latch. Acting in particular means that the electrical coil induces a magnetic force between two movable parts of the locking mechanism, or between the door opener housing and a movable transmission part of the locking mechanism, or between a movable transmission part of the locking mechanism and the door release latch, in order to block movement of the door release latch.
  • the electrical coil is magnetically conductively connected to or integrated into a movable gear part of the locking mechanism and / or the door opener housing and / or the door opener latch, in such a way that a magnetic field generated by the coil acts directly between these parts.
  • Locking mechanism is preferably understood to mean a switchable transmission which releases or locks a movement of the door opener latch.

  • the electrical coil can have at least two coil parts or at least two separate coil windings, a first part of the coil or a first coil winding being connected to the housing or arranged within a wall of the housing, and a further part of the coil or a further coil winding can be inside a movable gear part of the locking mechanism, in particular be arranged within the change and / or within the armature, and / or be designed to be integrated into the door opener latch,
  • This holding force can be additionally increased by preferably providing that the components of the locking mechanism and / or the door opener housing and / or the door opener latch have a ferromagnetic material or are formed from such.
  • part of the housing of the door opener or part of the wall of the housing can be designed to be magnetically conductive and form a coil core or a coil pot for the part of the electrical coil connected to the housing or the coil winding connected to the housing. This allows the magnetic field lines to be bundled well without the need for additional components.
  • the wall of the housing can be designed in several parts and the housing part receiving part of the coil or a coil winding can be designed to be exchangeable.
  • the housing part receiving a part of the coil or a coil winding can preferably be fastened to the housing via a releasable connection.

  • the cable transition runs in the area of the pivot bearing of a movable part of the locking mechanism. This makes it possible for the cable transition between the immovable part of the door opener housing and the movable part of the locking mechanism to experience as little torsion as possible and to prevent a cable break.
  • the at least two parts or at least two windings of the coil are arranged directly adjacent to one another in the blocking position, in particular in the blocking position they are at their smallest distance from one another.
  • the part of the coil arranged within a movable gear part of the locking mechanism or the corresponding coil core is flush with the surface of the gear part, and / or that the second part of the coil or its coil core connected to the door opener latch or integrated in the door opener latch is flush with the surface of the door release latch facing the change.
  • the flush termination of the coil part or coil core to the surface of the door opener latch or a gear part enables the two coil parts to be in direct contact in the locked position. When energized, the two coil parts are in direct contact with one another and produce a high holding force.
  • the change has a recess into which a nose of the door opener latch engages in the locked position, preferably engages in a form-fitting manner in order to lock the door opener latch.
  • This has the advantage that the holding force of the door opener is increased not only via the magnetic force, but also by means of a positive connection between the change and the door opener latch.
  • the nose of the door opener latch and / or the recess of the change has or have an inclined contact surface such that the door opener latch acts upon the change away from the door opener latch when pivoting.

It can also be provided that the coils arranged next to one another can be electrically connected in series in order to increase the operating voltage of the door opener.
  • the door opener has a digital bus interface with a switching device which interacts with the two coil parts in order to remotely switch or adjust the operating voltage of the door opener between a higher voltage and a lower voltage.
  • the door opener can have a control device which switches the two coil parts from serial operation to parallel operation for a preferably adjustable period of time and then switches back to serial operation in order to increase the holding force of the door opener. Due to the pulsed switchover between serial and parallel connection of the two coil parts, the door opener can temporarily develop a higher holding force.
  • the pulse duration is dimensioned so that there is no thermal overload of the door opener in parallel operation.
  • control device periodically switches the two coil parts between serial operation and parallel operation, to increase the holding force of the door opener or to set the operating voltage of the door opener.
  • the door opener has a control device which switches the two coil parts for a defined, preferably adjustable period of time, in opposite polarity, around the door opener latch switch to the release position.
  • the invention relates not only to the electric door opener as such, but also to a method for operating the door opener according to the invention, the door opener having a movable door opener latch which is switched between a locked position and a release position by a locking mechanism with a movably mounted gear element, by an electrical coil interacting with the locking mechanism and / or the door opener housing and / or the door opener latch.
