Definitions

  • the invention relates to an electrically operable device for locking hinged door leaves in the closed position and to open locked in the closed position door leaves, wherein the pivotable door is held by frictional engagement in the closed position.
  • a device according to the prior art is for example from the US 4,981,322 known.
  • hinged door panels locks are generally known in which - mechanically or electromechanically actuated - a movable latch is brought into the closed position and positive engagement, the movement of the hinged door is prevented by this locking bolt in a backdrop-shaped recess of the fixed door frame or fixed Door leaf engages.
  • Unlocked hinged door leaves which are held in the closed position by the latch, can only be opened by an additional door opening device, which can be electrically operated.
  • additional door opening devices which are arranged in the door frame or in the fixed door leaf.
  • a door opening means various electrically actuated structures are known in which a closing plate is unlocked by a magnetic field generated by a magnetic coil. After unlocking the positive engagement between latch bolt and backdrop-shaped recess is canceled.
  • the aim of the invention is to reduce the susceptibility of door closing and opening devices to reduce the cost of Bauauf- and maintenance and to ensure a safe closing of a hinged door leaf in the closed position and hereafter a safe opening.
  • the invention has for its object to develop for pivotable door a device in which both the door closing and locking device as well as the door opening device form a structural unit and to allow the closing of a hinged door leaf, which closes against a door seal, said Combination of a closing and opening device to be operated remotely.
  • an electromagnetic closing and opening device designed according to the invention is installed on the door side.
  • This consists of a two pole plates 2; 3 having electromagnetic device which is housed in a frame structure 4, wherein this is mounted on a cuff plate 5 made of non-magnetizable material, such as brass.
  • This electromagnetic device consists of a yoke 6 and of a yoke 6 enclosing winding 7 for generating an electromagnetic field.
  • the yoke 6 is provided with two pole plates 2; 3 connected. These consist of a material which still has a low residual magnetism after the electromagnetic field has dropped.
  • a closing counterpart for the provided in the door frame 1 or in the passive leaf electrically active part of the electromagnetic closing and opening device consists of a non-magnetizable material consisting of Stulpblech 9, on which a frame 10 is attached.
  • a slightly horizontally displaceable, U-shaped counter-pole piece 11 is provided, which is connected to a, provided in the frame 10 return spring 12.
  • the inventively designed device can be designed either as a closing variant or as an opening variant.
  • the counter pole piece 11 is made of soft iron and when applying a voltage to the winding 7 of the electrically active part, the closing and opening device comes into a closed position.
  • the counter-pole piece 11 consists of a permanent magnet and the electrically active part of the closing and opening device according to the invention is used to open a closed door leaf by a magnetic field is generated by applying a voltage to the winding 7 of the electrically active part the same pole those of the permanent magnet are opposite. As a result, the closing force of the permanent magnet is canceled.

  • the operating principle of the device in the closing variant is that, when the pivotally arranged door leaf 8 has been brought into the closed position, the Schmidtpol lake 17 of the Gegenpol realizedes 11 in the region of the electromagnetic field of the electrically active part of the closing and opening means come and the Schwarzpol lake 17th of the built-in pivoting door 8, slightly movable Gegenpol realizedes 11 are tightened and lock the pivoting door 8 in the closed position, characterized in that on the one hand a frictional connection between the pole faces 18 of the pole plates 2; 3 and the Gegenpoldon 17 of the movable Schmidtückes 11 by closing the electromagnetic field lines and on the other hand by the engagement of the intermediate piece 13 in a space 14 between the pole plates 2; 3 creates a positive connection.
  • the pole faces 18 and the counter pole faces 17 come through the magnetic field of the permanent magnet in the closed position and by the engagement of the intermediate piece 13 in a free space 14 between the pole plates 2; 3 arises in addition to the magnetic holding force a positive connection.
  • the angle of attack 22 is for the pole faces 18 of the pole plates 2; 3 and for the Jacobpol lake 17 of the Gegenpol Swisses 11 in the closing direction 23 of the door leaf 8 an acute angle of 1 to 3 degrees, whereby the distance between the pole faces 18 and Martinezpolvis 17 is different in a position shortly before the closed position of the door leaf 8 in the door frame 1 ie between the pole face 18 of the pole plate 2 and the opposing pole face 17 of the counter pole piece 11 which is in opposition thereto is larger than the distance between the pole face 18 of the pole plate 3 and the opposing pole face 17 of the counter pole piece 11 which is in opposition to this.
  • the angle of attack 23 of the end face 21 of FIG Intermediate piece 13 is designed as an acute angle in the opening direction of the door leaf 8 and is also 1 to 3 degrees.
  • the electrically active part consisting of winding 7, yoke 6 and pole plates 1; 2, in which the holder in the door frame 1 serving frame structure 4 is elastically mounted and for this purpose a thrust bearing 25 is provided.
  • the counter pole piece 11 is elastically supported in the frame 10 provided for this purpose.
  • a further technical measure for the secure positioning of the counter pole piece 11 in the closing phase in the closed position is provided according to the invention on the counter pole piece 11.
  • This has a nose-shaped projection on the side of the Gegenpol foundedes 11, which is opposite to the closing direction. As a result, it is ensured that the pole faces 18 and the counter-pole faces 17 can only move toward one another as soon as the closed position is reached.
  • the magnetic field collapses as a holding force and it acts only a residual magnetism, the movable door 8th holds in the closed position.
  • the return spring 12 which is arranged on the rear leg of the frame 10, is effective and the intermediate piece 13 with the counter pole piece 11 through the Return spring 12 is brought into a starting position, in which the intermediate piece 13 is no longer in the free space 14 between the pole plates 2; 3 intervenes.
  • the advantage of the solution according to the invention is that the closing and opening device has no moving parts that are subject to wear or can be destroyed by external violence.
  • the operation of the device according to the invention is carried out either by applying a voltage to the electromagnetic Winding 7 via a remote control, provided that the person who operates the door operation, is located within the building, where an electrical switch is provided for the operation.
  • the activation of the closing and opening device takes place, for example, after relapse of the movable door leaf 8 in the door stop 16 of the door frame 1 sensor-controlled automatically.
