Definitions

  • the invention relates to an electromagnetically controlled door opener for access doors with a hollow cuboid housing in which a striking plate is pivotally mounted.
  • the striking plate carries a cam that drives a one-armed lever.
  • the end of this lever rests on the edge of a control lever that carries an elongated magnetic armature.
  • This anchor is held in the rest position by the force of a spring, in which the striking plate is locked.
  • the electromagnet has a U-shaped yoke with two powerful coils. When the coils are energized with alternating current of low voltage, the yoke pulls the spring-loaded armature with the aid of lifting work, so that the cutting edge releases the lever and the striking plate. Since the magnetic force has to move the armature over a large air gap, a relatively large actuation current is required.
  • the invention has for its object to significantly reduce the magnet volume and the power requirement of such door openers.
  • the manufacture of the magnet should be simplified and made cheaper.
  • 1 is a cuboid housing, which has a trough-shaped recess 1a.
  • a striking plate 2 is pivotally mounted in a further shallow recess 1b.
  • the right edge 2a protrudes beyond the edge of the housing 1 and holds the latch of the door, not shown.
  • Two cylinder pins 3 and 4 which are inserted into bores of the housing 1, are used to mount the striking plate.
  • the striking plate 2 has a projection at the top left, which is designed as a drive wedge 2b. This wedge acts on a drive slide 5 shown in dotted lines, which has a wedge surface 5a.
  • a control slide 6, which has a locking pin 6a is mounted on the drive slide 5, which is only partially visible.
  • Both slides are movable in the longitudinal direction and provided with elongated holes through which a screw 7 passes.
  • a coil spring 8 is arranged between the control slide 5 and the housing 1.
  • Another coil spring 9 is located between a bevel 5b of the drive slide 5 and the control slide 6.
  • 10 denotes an electromagnet, which consists of a yoke 10a fixed to the housing, a coil 10b and an armature 10c, which rests pivotably on the control slide 6.
  • the door opener works as follows: If the striking plate is pivoted counter-clockwise when the electromagnet is not energized, it moves Wedge 2b, the wedge 5a and thus the entire drive slide 5 in the direction of the arrow 11.
  • the control slide 6 is carried along via the bevel 5b and the spring 9 because the armature 10c can detach from the yoke 10a.
  • the locking pin 6a moves under the drive wedge 2b until a locking surface 2b1 is seated on this pin and blocks the striking plate after a advance required for the control process.
  • Fig. 4 with 12 and 13 elongated holes are designated, in which movable nuts can be inserted through side openings.
  • the door opener is attached to a door fitting with 2 screws and can then be adjusted when installed.
  • FIG. 5 shows the trough shape of the housing 1, the U-shape of the drive slide 5 and the shape of the control slide 6 mounted in the drive slide.
  • the rear of the drive wedge 2b the wedge surface of which can be seen, can be seen the inclined surface 5a of the drive slide 5 rests.
  • a distance of about 2-3 mm remains in the rest state shown, so that the striking plate 2 and the slider 5, 6 can perform a certain advance in order to bring about the locking effect according to FIG. 2.
  • the magnet 10 has no lifting work to do.
  • the yoke 10a only needs to hold the anchor 10c optimally offered to it. A single small coil and extremely low excitation power are sufficient for this.
  • the magnet can therefore easily be fed from dry batteries with a few volts DC.
  • Battery-operated door openers are particularly advantageous in internal access systems, the opening impulse of which comes from a coding unit which is controlled by a magnetic stripe card or keypad.
  • the trigger pulses and the electronics can then be fed from a single battery, which keeps installation costs low.
  • the electric door opener can also be accommodated in the door leaf instead of in the door frame. An associated trap would then have to be stored in the frame.
