Definitions

  • the invention relates to a locking device for a door provided with a door closer, with a sliding arm arranged between the door leaf and frame, which is articulated at one end on the leaf or on the frame and at the other end in one on the frame or on the door arranged guide rail is slidably guided and with an electrically lockable holding device with a movable stop which is forced under the action of a spring into the path of movement of the slide arm, a movable bearing on which the spring is supported, and an electromagnet with which the movable bearing cooperates , wherein the electromagnet is arranged outside the path of movement of the slide arm.
  • Such a device is known from DE-OS 36 04 084. It uses several levers to translate the magnetic force in order to obtain a relatively large holding force. The levers result in a relatively voluminous, complicated construction. It is also disadvantageous that dirt from the outside easily attaches to the adhesive side of the magnet.
  • the invention has for its object to provide a locking device of the type mentioned, which is more compact and allows a high holding force.
  • the invention solves this problem by that the armature plate is arranged on the side of the electromagnet facing away from the movement path of the sliding arm, that the movable latching lug is mounted in a recess in the electromagnet and can be displaced perpendicularly or approximately perpendicularly to the anchor plate plane, that the spring is supported on the one hand on the anchor plate and on the other hand on the locking lug.
  • the individual components can be nested to save space. The entire unit is more compact, so that a relatively large magnet, for. B. a composite magnet with several coils can be used without a larger volume is required.
  • the electromagnet has a plurality of electrical coils and the recess is arranged in an intermediate space between the coils.
  • the locking lug is designed as a plastic injection-molded part, in which a spacer screw cooperating with the anchor plate is injected and the spring engages.
  • This design has special manufacturing advantages.
  • the fact that the locking lug is designed as a plastic part also prevents interfering interactions with the electromagnet.
  • a high degree of functional reliability is obtained if a plastic sleeve arranged in the recess is provided as the guide device for the latching lug.
  • a lever can also be provided as a guide device of the latching lug, which, for. B. is rigidly connected.
  • the locking device according to the invention is used in conjunction with an overhead door closer 1 with a sliding arm 2.
  • the sliding arm 2 is guided in a rail 3 in which the locking device is integrated.
  • the door closer 1 is mounted with its housing 4 on the door leaf 5 and the rail 3 on the door frame 6. In other corresponding versions, this can also be reversed, so that the door closer housing is attached to the frame and the rail on the door leaf.
  • a drive unit, not shown, and a driven closer shaft 7 are mounted in the door closer housing 4.
  • the closer shaft 7 is rotatably connected to the slide arm 2.
  • the free arm 2 is guided with its free end in the rail 3.
  • the rail 3 has a multi-chamber housing 8 with a plurality of chambers extending in the longitudinal direction of the rail.
  • the locking device 10 is arranged in a chamber 9.
  • the sliding arm 2 is guided in another chamber 11.
  • Two opposite web edges 12 are arranged between the chambers 9, 11.
  • the web edges 12 delimit an opening 12 a extending in the longitudinal direction, with which the chambers 9, 11 are connected to one another.
  • the slide arm 2 is guided in the lower chamber 11.
  • the chamber 11 has a slot 13 which is accessible from below and into which the slide arm 2 engages from below with a slider 14 attached to its free end.
  • the slider can also be designed as a roller.
  • the locking device 10 is arranged in the upper chamber 9.
  • the device 10 has a body 15 in the form of a steel block, in which two electrical coils 16, 17 are inserted.
  • the body 15 has between the two coils 16, 17 a recess 18 with a round cross section, into which a plastic sleeve 19 is inserted.
  • a slide 20 is axially movable.
  • a steel plate 21 is mounted on the upper side of the body 15 and adheres to the body 15 magnetized in the area of the coils 16, 17 when the coils 16, 17 are energized.
  • the body 15 has a stepped edge 22 on both sides in the region of its lower longitudinal edges, with which it is supported on the respective web 12.
  • a locking lug 25 is mounted, which protrudes into the lower chamber 11 into the movement path of the slider 14.
  • the locking lug has a steeper inclined surface 25 a on the left and a flatter inclined surface 25 b on the right side.
  • the surface 25 a forms the stop surface for the slider 14 in the locking position. With the surface 25 b, the slider interacts when the door is opened.
  • the locking lug 20 is designed as a plastic injection-molded part, into which a spacer screw 26 is injected, which is supported with its free head end 27 on the upper side of the anchor plate 21. Between the locking lug 20 and the anchor plate 21, a compression spring 30 is mounted, which urges the locking lug 20 with the locking lug 25 into the movement path of the slider 14 in the lower chamber 11.
  • the armature plate 21 thus forms the movable bearing of the slide 20 or the detent 25 in the area between the coils 16, 17.
  • a leaf spring 35 is mounted, which acts as a return spring and urges the plate 21 to the body 15.
  • a clamping screw 40 is screwed into the body 15, which is supported with its projecting free end on the upper limiting web 31 and clamps the body 15 in the chamber 9 in this way.
  • the body 15 is provided with a plastic cover 41, 42 at its ends. At the left end in FIG. 2, the electrical lead 45 is connected to the body 15. It is guided in chamber 9.
  • a bellows 46 is arranged below the feed line 45. It is attached to the left end of the body 15 and rests on the webs 12. Thus, it covers the opening 12 a and prevents the supply cable 45 from falling into the lower chamber 11 through the opening 12 a or protrude.
  • the locking device 10 shown can be locked with the clamping screw 40 in any position in the longitudinal direction of the rail 3.
  • the device according to the invention works as follows.
  • the steel body 15 is magnetized, that is, the electromagnet is switched on.
  • the locking device 10 is switched on. Accordingly, the electromagnet and thus the locking device are switched off by switching off the current.
  • the slider 14 passes the locking lug 20 by engaging the inclined surface 25 b and pushing the locking lug 20 into the magnet body 15 regardless of whether the magnet is switched on or off.
  • the locking lug 20 is displaced by compression of the compression spring 30.
  • the anchor plate 21 remains attached to the magnetic body 15.
  • the plate 21 can lift off, so that the latch 20 is moved upwards together with the anchor plate 21 when the slide 14 passes.
  • the compression spring 30 remains unchanged.
  • a further closing of the door 5 takes place only when the power supply to the magnet is switched off or the door 5 is pushed over by hand.
  • the latch 20 When overpressing by hand, the latch 20 is also moved upward when passing the slider 14, but the anchor plate 21 remains adhering to the magnetic body 15 and instead the spring 30 is compressed to deflect the latch 20.
  • the locking angle of the door 5 can be adjusted by any choice of the position of the locking device 10 or the displaceable body 15 in the longitudinal direction of the rail 3. For adjustment it is necessary to clamp the locking device 10 in the corresponding position with the screw 40.
  • Two parallel arms of the lever 49 are preferably provided on both longitudinal sides of the body 15.
  • the magnet is arranged on only one side of the locking lug 20.
  • the locking lug 20 is also mounted in the steel block 15, also in the immediate vicinity of the magnet.
  • the movable bearing on the armature plate 21 is formed adjacent to the magnet or the coil 17 and the armature plate 21 lies on the body 15.
  • the bearing surfaces are ground flat.
  • the anchor plate 21 has an angled end 50 as an abutment at its end projecting above the block 15, with which end it can interact with the upper web 31.
  • the anchor plate 21 lifts off when the electromagnet is switched off under the action of the latch 20 when the door is opened or closed, it is supported with its right end on the block 15 and rotates clockwise in the process.
  • the anchor plate 21 in this case is supported with its end 50 on the limiting web 31 and rotates clockwise.
