Definitions

  • the invention relates to an electromagnetic door lock for locking a door, in particular a sliding door in one of its end positions.
  • Locking systems for fire barriers are known, with which the spread of fires in buildings is stopped and the spread of fire smoke and gases is prevented to neighboring rooms or buildings.
  • These systems essentially consist of a fire detector, a smoke protection switch and an adhesive or electromagnet with which a fire protection door in your is held in the open position.
  • the smoke protection switch controls the corresponding holding magnet in such a way that when signals from a fire alarm are received, the holding force of the holding magnet breaks down and the door is then closed by an automatic door closer.
  • sliding door systems are known in which magnets are attached to the door flanks and to the door frames in such a way that their poles of the same name point towards one another. With these magnets it is achieved that the sliding door system can be lifted out of a lowered position, in which the door is generally in the closed state, without great effort and thus opened. Electromagnets can also be used for this, which are controlled by sensors on the door handles. The use of such magnets makes operation easier, particularly in the case of relatively heavy doors, but it is nevertheless necessary to open and close the door by hand.
  • the invention has for its object to provide an electromagnetic door lock for locking a door, in particular a sliding door in one of its end positions, which is particularly suitable for use in rail vehicles and requires little mechanical and electrical effort.
  • the approach piece acting on the limit switch is preferably spring-mounted, so that the installation tolerances can be relatively high.
  • the limit switch preferably acts on a time relay for activating the electromagnet for a presettable period of time.
  • the electromagnet preferably acts on the approach piece and thereby holds the door in its end position. This has the advantage that the door can be closed by hand even before the predetermined time has expired without too much effort, since the starting piece is released from the electromagnet by a relatively small movement of the door and the door is thus unlocked.
  • the door lock according to the invention is used in particular in a device for operating a sliding door, which is locked in its open position for a predetermined period of time and which has an automatic mechanical closing device for closing the door after a certain period of time.
  • a sliding door 1 is provided with two support arms 2, 3 with which it runs in a guide and holding rail 4.
  • the sliding door 1 shown with solid lines is in this example in its closed position, while the position in the open state is indicated by dashed lines.
  • An automatic locking device is provided on the door, which is formed on the one hand from a lever arm 12 pivotably mounted on the door at a pivot point 15 and a compression spring arrangement 13 engaging on this lever arm and on the other hand from a drain rail 11 which is fixedly attached to the door frame.
  • This drain rail is inclined in the manner of an inclined plane and falls in the plane shown in FIG. 1 in the direction of the closed position of the door.
  • this drain rail 11 runs a roller 14 of the lever arm 12, which is biased by the compression spring assembly 13 in the rotational position shown by solid lines.
  • a holder 50 is also connected to the approach piece 9, which actuates a limit switch 7 attached to a fixed holder 5 when the door is opened. Switch contacts are closed by the approach piece 9, so that an electromagnet 6, which is also attached to the fixed holder 5, is activated via a time relay 8.
  • the electromagnetic field thus created acts on the starting piece 9 made of the corresponding material and holds it and thus the sliding door 1 with a certain minimum holding force in the open position.
  • the supply current of the electromagnet is conducted via the time relay 8 acted upon by the limit switch 7, after an adjustable delay time has elapsed, e.g. the power supply is interrupted again after about 1 - 20 seconds. This also breaks down the electromagnetic field, so that the holding force disappears and the door is moved back into its closed position by the automatic locking device.
  • FIG. 2 shows the fixed to the guide and support rail 4 fixed bracket 5 with the attached limit switch 7 and an embodiment of an electromagnet 6.
  • the limit switch 7 has a contact arm 20, which rests in a pivotable bearing 22 and by the force of a spring 21 is applied, which biases this in the direction indicated by arrow 23.
  • the holding plate 5 and the limit switch 7 are attached so that the contact arm 20 with slider 24 is pivoted by the approach piece 9 when the door opens against the force of the spring 21. This pivoting movement closes the contacts of the limit switch 7, so that, as described above, a current can flow through the electromagnet 6 via the timing relay 8 and the starting piece 9 is held in place by the magnetic field generated.
  • Figure 3 shows a section along the line A-A in Figure 2.
  • the profile of the guide and holding rail 4 can be seen, which e.g. is designed as a ball guide.
  • the fixed bracket 5 is attached to the guide rail in this embodiment.
  • the limit switch 7 with contact arm 20 and the electromagnet 6 can be seen.
  • Figure 4 shows the holder 50 attached to the door with the approach piece 9 in detail.
  • This illustration shows in particular the axially resilient mounting of the starting piece, which is brought about by a spring 41, so that the starting piece is movable in the direction of the double arrow 42 and the door position does not have to be exactly predetermined.
  • the approach piece 9 also has a beveled area 43 on the end face, along which the slide piece 24 of the contact arm 20 slides during the last part of the opening movement of the door and thus causes the above-described pivoting movement against the force of the spring 21.
  • part of the drain rail 11 and the guide and holding rail 4 are shown in this illustration.
  • Figure 5 shows a view according to arrow B in Figure 4.
  • the guide and holding rail 4 can be seen, in which the support arm 2 of the sliding door is guided.
  • the compression spring arrangement 13 which, as described with reference to FIG. 1, prestresses the pivotable lever arm 12 in a clockwise direction, as a result of which the roller 14 runs on the drain rail 11 and causes the door to close automatically.
  • the holder 50 with the approach piece 9 and the chamfered area 43 on the end face of the approach piece 9, which acts on the limit switch 7, can also be seen.
