Definitions

  • the present invention relates to an electromagnetic door lock, esp. For doors in escape routes, with an electromagnet, which cooperates with an anchor plate.
  • the anchor plate with a countersunk screw and a rubber buffer is firmly bolted to a lintel or door.
  • the position of the anchor plate can only be influenced to a very limited extent by the tightening torque of the countersunk screw.
  • an electromagnetic door lock esp.
  • an electromagnet which interacts with an anchor plate
  • the anchor plate is provided with an adjustment, which is freely rotatably mounted on the anchor plate and which with a the door or on the door frame defined threaded rod cooperates.
  • the anchor plate can be easily and easily adjusted.
  • the adjusting unit has an internally threaded sleeve with a radially projecting collar.
  • the collar advantageously transitions with a conical section into the internally threaded sleeve.
  • the female threaded sleeve is screwed according to a preferred embodiment of an external thread of the threaded rod.
  • the threaded rod For screwing the threaded sleeve into a arranged on the door or on the frame of the door screw, the threaded rod according to an advantageous embodiment, at its projecting into the threaded sleeve end face a recess u. a. for engaging a tool.
  • the collar is advantageously provided with an axial passage opening, which allows access to the recess in the threaded sleeve.
  • the collar has on its side facing away from the female threaded sleeve at least one engagement opening for engagement of a special tool, by means of which the adjusting unit can be adjusted relative to the threaded rod.
  • a special tool is therefore used so that an unauthorized person has no opportunity to change the position of the anchor plate.
  • the adjustment is provided according to a preferred embodiment on the side facing away from the threaded rod with a lid.
  • the threaded sleeve is provided according to an advantageous development on the side facing away from the collar with a securing element.
  • the anchor plate is freely rotatably fixed between the collar and the securing element.
  • the securing element can be supported on the anchor plate via an elastic buffer.
  • the elastic buffer also ensures an angle compensation.
  • the elastic buffer can, for. B. Vulkollan, rubber o. The like. Exist.
  • a washer can be arranged between the securing element and the elastic buffer.
  • the elastic buffer and the washer may also be formed as a one-piece rubber-metal member.
  • the securing element can be designed as a nut, preferably as a hexagon nut, which can be screwed onto an external thread of the hexagon socket sleeve.
  • the securing element can also be designed as a shaft securing ring, which can be latched into a circumferential groove of the internally threaded sleeve.
  • the electromagnetic door lock cooperates with an anchor plate 1, which can be arranged on a door or on its frame to ensure a locking of the door together with an electromagnet.
  • the anchor plate 1 is provided with a through-hole 2 having a first portion 2a and a second portion 2b.
  • the first section 2a which is larger in diameter than the second section 2b, merges via a conical flank 2c into the second section 2b.
  • an adjusting unit is used, which is indeed fixed to the anchor plate 1, but can rotate freely with respect to the anchor plate 1.
  • the adjusting unit has a collar 3, which merges with a conical region into a smaller diameter internally threaded sleeve 4.
  • a threaded rod 5 is screwed, which in the FIGS. 1 and 2 is shown only partially and which serves to fix the anchor plate 1 to a door or a door frame.
  • the threaded rod 5 is provided at its screwed into the female threaded sleeve 4 section with an end-side recess 6, in which a tool for securing the threaded rod 5 on the door or the door frame can engage.
  • the recess 6 may be formed as a hexagon socket, in which a suitable tool, for. B. an Allen key can be used.
  • the collar 3 is provided with a through hole 7.
  • the collar 3 has on its side facing away from the internally threaded sleeve 4 at least one engagement opening 8 for receiving a lid 9 and for engaging a special tool, by means of which the adjusting unit relative to the threaded rod 5 can be adjusted.
  • two engagement openings 8 may be provided into which a special tool equipped with two corresponding pins is inserted can.
  • the use of such a special tool prevents unauthorized persons from making an adjustment of the anchor plate 1.
  • the adjusting unit in particular its collar 3, which has the passage opening 7 and the engagement openings 8, is covered on the side facing away from the threaded rod 5 with the cover 9, which serves to avoid a remanence between the anchor plate 1 and a co-operating with the anchor plate 1 electromagnet ,
  • the lid 9 is provided with a preferably made of plastic ball head 14, which serves to separate the components against the adhesion force when no magnetic force acts.
  • the internally threaded sleeve 4 is provided on the side facing away from the collar 3 with a securing element 10, 11, which is supported on the anchor plate 1 via an elastic buffer 12, for example Vulkollan, rubber o. The like. Possibly. between the securing element 10, 11 and the elastic buffer 12 is still a washer 13 ( FIG. 2 ) be provided.
  • the buffer 12 is used to compensate for lateral forces that are applied through the door and the angle compensation.
  • the anchor plate 1 is thus held freely rotatable between the collar 4 and the elastic buffer 12.
  • the above-described embodiment is in both in the FIGS. 1 and 2 shown embodiments the same. The only difference is the design of the fuse element and the attachment of the cover 9 ..
  • the securing element consists of a nut 10 which is screwed onto an external thread of the internally threaded sleeve 4.
  • the nut 10 may be, for example, a flanged hex nut. Through the flange better support of the elastic buffer 12 is achieved.
  • the securing element consists of a shaft securing ring 13, which is inserted into a circumferential groove of the internally threaded sleeve 4.
  • the lid 9 is received in at least one engagement opening 8 of the collar 3, while according to FIG. 2 is inserted into the anchor plate 1.
  • the anchor plate 1 by turning the adjusting unit, which consists of the collar 3, the internally threaded sleeve 4, the buffer 12, possibly the washer 13 and the securing element 10, 11, with a special tool in a certain range, for example + / - 2 mm with respect to the door or door frame.
  • the electromagnetic door lock has two types of tolerance compensation: an "automatic tolerance compensation" on the buffer 12, which counteracts a delay or setting of the door and a tolerance compensation on the adjustment of the threaded rod 5, which is used for adjustment during assembly ,
