Definitions

  • the invention relates to an anti-panic bar in the Preamble of Claim 1 Art.
  • Such an anti-panic bar has a push bar which itself along the width of a door and between the ends of respective reversible rotatable levers that extend with respective shafts are splined which are rotatable in respective Brackets are installed with their base plate on the Door are attached.
  • the brackets have facilities that when pushing down the push rod opening an attached one effect or built-in lock, and return devices on which the push rod is not depressed or Bring the rest position back.
  • each bracket at one end or the other end of the push rod can be attached, with the rotating lever too have a possible stroke for this purpose, the same two Includes working strokes, one below the other with respect to the center of the possible stroke are symmetrical.
  • doors of emergency exits are public spaces and areas provided for the public Intended use (supermarkets, auditoriums, %) as well as businesses and the like.
  • the invention has for its object an anti-panic bar to create the type mentioned, which has a device, which in a simple manner without affecting reversibility holding the push rod in the depressed position enables.
  • the holding device for this type of reversible anti-panic bar formed in that at least one of the brackets of the push rod the shaft a radial Has pegs such that each of the alternative reversible Movements of the rotatable lever when depressing the Push rod the rotational movement stroke of the radial pin between respective start and end positions is that of the rest position or the depressed position of the push rod, in the rest position of the radial pin opposite and adjacent to the end of a first locking hook a sliding plate, which is in transverse to the shaft over a Longitudinal stroke parallel to the base plate of the bracket by one dimension is displaceable, similar to the radial dimension of the pin while the radial pin is in the depressed position opposite to the retaining edge of the first locking hook and is arranged behind this.
  • the slide plate is on the Base plate of the bracket and has a second locking hook on that corresponding to the direction of movement of the slide plate Longitudinal opposite the first locking hook and is separated from it by such a distance that if one of the locking hooks is adjacent to the rotary motion circle of the radial pin, the other locking hook is adjacent to the circumference of the shaft.
  • the slide plate points in their level on the base plate of the bracket two Balls on the blind holes by respective bias springs are arranged biased towards the outside, the blind holes a mutual in the longitudinal direction mentioned Have a distance equal to the size of the longitudinal stroke of the slide plate, always only one of these balls with an opening is aligned, which is arranged in the base plate of the holder is and has a diameter which is suitable is smaller than that of the balls.
  • the operation of the bracket device is extremely simple. If the anti-panic bar is reversible according to one of the possible Operating modes is installed when the Push rod in the depressed position of the radial pin beyond the end of the adjacent pawl, whereupon with a corresponding actuation of the displaceable Push button the slide plate and thus this locking hook Shaft is moved in which the radial pin is located, thereby holding the latter in place and making it impossible the push rod will return to its rest position, which on the other hand keeps the lock mechanism open.
  • the position adjacent to the shaft is a any of the locking hooks requires a position of the sliding plate, which coincides with that in which the holding effect exercises. Therefore, it is enough with a set of two spring-loaded Balls (in the sliding plate) and the single opening (in the Base plate of the bracket) that in the two end positions the slide plate and the resulting holding states a certain engagement of the depressed push rod that is sufficient to ensure that such conditions not in a random manner due to blows or vibrations be lifted in the normal use of the door and the Anti-panic bar occur.
  • two microswitches which form part of an electronic control circuit and whose shift arm in the longitudinal trajectory of each Protrudes end portions of a driver that is reversible Way the force generated when depressing the push rod transmits and opening the lock mechanism when moving of the driver from a middle position, that of the rest position the push rod corresponds to one or the other End position causes, depending on the used reversible modes of operation, the depressed position corresponds to the push rod, with the microswitch accordingly the alternative end positions of the postponement of work Driver are arranged.
  • both Brackets equipped with the holding device and the microswitches can be, or that this is only one of the brackets the case is, or that the holding device on the a bracket is arranged while the microswitch on the other bracket are arranged.
  • a holding device for the open or depressed Position of a reversible anti-panic bar shown the has a push rod 1 which extends along the width of a Door 2 and between the ends of respective reversible rotatable Lever 3 extends wedged with respective shafts 4 are.
  • the shafts are rotatably installed in respective brackets 5, which are attached to the door via their base plate 5a and Devices that open when pressing the push rod 1 of an attached or installed lock, and / or Return devices to the non-depressed or rest position have the push rod 1.
  • the anti-panic bar also has (Fig. 17) respective microswitches 16 on the depressed state of the push rod 1 can be reversibly determined.
  • the holding device for holding the depressed position the push rod 1 (open lock) is according to the invention formed in that in at least one of the brackets 5th the shaft 4 has a radial pin 6 such that at each of the alternative reversible modes of rotation Lever 3 when depressing the push rod 1, the working rotary stroke this rotatable pin 6 between the respective start and end positions lies, the rest position or depressed position correspond to the push rod.
  • first locking hook 7 In its rest position it is radial pin 6 opposite and adjacent to the end of a arranged on a slide plate 9 formed first locking hook 7, which in the transverse direction of the shaft 4 via a longitudinal stroke 8 parallel to the base plate 5a of the bracket 5 to an extent is displaceable, which is similar to the radial extension of the Pin 6 is while in the depressed position of the push rod this radial pin 6 on a holding edge of the first Locking hook 7 can be applied.
  • the sliding plate 9 is on the Base plate 5a of the bracket 5 and has a second locking hook 10 which has the first locking hook 7 in the longitudinal direction lies opposite and has such a distance from it, that if one of the locking hooks 7 or 10 is adjacent to the Extent of the rotational movement of the radial pin 6 is located other locking hooks 10 or 7 adjacent to the circumference of the shaft 4 lies.
  • the slide plate 9 is through a recess in the Holder 5 connected to a displaceable push button 11, the one on the outside on the edge of a bracket cover 5 is present.
  • the slide plate 9 has in its on the base plate 5a of the bracket adjacent level two balls 12, which under Spring preload by respective springs 13 in blind bores 14 are attached, their distance in the longitudinal direction the same dimension has, as the longitudinal stroke 8 of the slide plate 9, always only one of the balls can be aligned with an opening 15, which is formed in the base plate 5a of the holder 5 and has a diameter which is suitably smaller than the diameter of the balls is 12.
  • FIGS. 2, 13 and 14 lie when pushing down the push rod 1 (transition from the Figure 2 to Figure 13) of the radial pin 6 (Fig. 13) below the holding edge of the first locking hook 7, whereupon by a Actuation of the sliding push button 11, the slide plate 9 is shifted so that it reaches the stop position (FIG. 14), with this movement the longitudinal stroke 8 is carried out so that the one furthest ahead (in the direction of displacement) Ball 12 leaves the opening 15, which then from the further back lying ball 12 is taken.
  • the microswitches 16 are operational in accordance with the alternative end positions the working movement of the driver 17 arranged.
  • FIG. 17 A simple view of Figure 17 shows that when depressed the push rod 1 the downward movement of the rotary lever 3rd the driver 7 moves to the left and the corresponding end part 17a actuated the switching arm 16a of the left microswitch in the figure.
  • the rotary lever 3 When the rotary lever 3 is in the reverse position moves, its downward movement calls for a displacement of the driver 17 to the right, so that of course Microswitch 16 is activated on this side, due to the interaction between the corresponding end part 17a and the switching arm 16a.
