Definitions

  • the invention relates to a fitting for connecting the wing pairs of a folding door having a plurality of wing pairs, the individual wings of which are hingedly connected to one another, with a support for fastening and guiding the two wings of the adjacent wing pairs by means of supporting and guide rollers on a guide rail, the adjoining wings two successive pairs of wings can be pivoted relative to one another by hinges and in the hinge area of two such adjacent wings, at least on the wing of one pair of wings, a driver is attached, which acts on an actuating device which, when the wing provided with the driver is pivoted, on the wing adjacent in the hinge area of the other pair of wings exerts a torque in the opening direction.
  • Such a fitting is known for example from DE-U-88 09 497.
  • double-armed roller levers are provided, one lever of which, depending on the actuation, acts on one of the two wings by a driver and which transmits the actuating force to the other wing in the opening direction.
  • the actuating levers In order to be able to achieve the desired opening paths, the actuating levers must each have a certain length. Due to the training as a double-arm angle lever, a large installation depth is required. This is disruptive with regard to the space to be used behind it.
  • the invention has for its object to provide a fitting for folding doors that is simple in construction and requires only a small depth.
  • the actuating device comprises a pulling wedge which is pivotally articulated at one end on the driver about a pivot axis parallel to the hinge axis of the hinges of the wing pairs and which is provided at its other end with diverging wedge surfaces, of which the one is supported on a sliding surface of the wing and the other on the sliding surface of the carrier with pulling action of the driver and that the wedge surfaces run parallel to the pivot axis.
  • the advantage is that only a few and easily manufactured components can be used.
  • the pull wedge is easy to manufacture and can also be used over the long term. Since the parts can be easily made of plastic, no special maintenance is required.
  • the carrier can be used without the use of the pulling wedges and drivers, so that the same basic elements can be used for all articulation points of the individual wings of the folding door on the guide rail.
  • the carrier and guide rollers can be connected to the carrier via separate carrier plates or sliders.
  • the drawing wedge is preferably designed as a plastic part and the wedge surfaces are part of two arms which are arranged at the end and diverge.
  • a significant advantage is achieved in that when the door is inadvertently closed, starting from the partially open state, the two arms of the pull wedge are open can otherwise spring without exerting significant forces on the attachment of the hinges. This prevents the hinges from breaking out.
  • the service life of the connection is therefore influenced favorably.
  • the end of the drawing wedge articulated on the driver has a swivel axis with a subsequent recess and the driver is provided with a snap hook-like closure and an elongated hole.
  • the driver is preferably also designed as a plastic injection molded part.
  • the wings of the adjoining pairs of wings each have a carrier and driver and pulling wedges.
  • the driver of one wing preferably has a part of the sliding surface for the pulling wedge associated with the driver of the other wing.
  • the carriers are connected to one another via a coupling element.
  • a folding door 1 which is formed from two pairs of wings 2, 3.
  • the two wing pairs 2, 3 each consist of wings 2a, 2b and 3a, 3b.
  • the two wings 2a, 2b and 3a, 3b are each articulated to one another via hinges 4.
  • the two wings 2b, 3a of the two adjoining wing pairs 2, 3 are connected to one another in an articulated manner by a fitting 6 and are guided in a hanging manner in an upper guide rail 7.
  • the other ends of the outer wings 2a and 3b are also provided with fittings 5 with which they in the overhead guide rail 7 are slidably guided.
  • the fitting 6 for connecting the two wings 2b, 3a of the two pairs of wings 2, 3 has the effect that when, for example, the wing 3b is pulled by hand in the opening direction, also for moving the two wing pairs 2, 3 into the open position a force is exerted on the wing 2b of the first pair of wings 2 in the sense of opening.
  • a force is exerted on the wing 2b of the first pair of wings 2 in the sense of opening.
  • an opening force is exerted on the wing 2a of the first pair of wings 2.
  • the wing 3a of the second pair of wings 3 is acted upon in the direction of rotation for pivoting into the open position.
  • the structure and parts of the fitting 6 are shown in more detail in Figures 2 to 7 and described below using the same.
  • the fitting 6 is constructed from two supports 8, which are designed symmetrically with respect to the pivot axis.
  • the two supports 8 are firmly connected to one another by a tab 10 screwed to them by screws 9.
  • each support plates 11 can be screwed on by means of screws 12 which are passed through an elongated hole in the support 8 and engage in a threaded bore of the support plates 11.
  • the support plates 11 carry the spaced support rollers 13, which are guided in the inner contour of the guide rail 7.
  • the door leaves 3a, 2b are held on the carrier 8 via hinges 17 on a flange plate 18, to which the other leg of the hinge 17 is fastened.
  • the height adjustment takes place via an adjusting screw 15, which engages through a threaded hole in a bent tab 14 of the support plate 11 and is supported with its end against a web 16 of the carrier 8.
  • the idlers 13 have horizontal axes of rotation.
  • the guide rollers 19 have vertical axes of rotation and are fastened to a slide 20 which is adjustable in the vertical direction relative to the support rollers 13.
  • the slider has two elongated holes 21 which are arranged at a parallel distance from one another and through which fastening screws 22 pass, which can each be screwed into threaded holes in the support plates 11 and which serve to clamp the slide 20 opposite the support plate 11.
  • the hinges 17 are recessed in a blind hole 23 which extends from the inner surface 24 of the wing 3 and are screwed by means of screws, not shown.
  • drivers 25, 25a and drawing wedges 26, 26a are attached in the area of each of the hinges 17 arranged at a height from one another.
  • the driver 25 is fixed in the wing 2b on its inner surface 24 by screws.
  • the driver 25a is fastened to the inner surface 24 of the wing 3a by screws.
  • the pull wedge 26a is assigned to this driver 25a.
  • the two pulling wedges 26, 26a are passed through openings in the respective supports 8.
  • the design of the pulling wedges 26, 26a can be seen from FIGS. 6 and 7. Starting from the end 27, which faces the driver 25, 25a, the drawing wedge 26, 26a divides into two arms 28, 29 which are at an angle to one another and form two wedge surfaces 30, 31 which extend away from one another.
  • the driver-side end 27 is provided with a recess 32 for threading and mounting the drawing wedge 26, 26a on the driver 25, 25a. Furthermore, it has a pivot pin 33, which with a like a snap hook formed end of the associated driver 25, 25a can be brought into engagement. As can be seen in relation to the driver 25a from FIG. 4, this has a tongue 34 which can spring back into an elongated hole 35 so that the pivot pin 33 can be inserted into the elongated hole 35. Then the tongue 34 springs back. The pivot pin 33 and thus the pull wedge 26, 26a is guided in the slot 35 via the pivot pin 33 and coupled to the driver 25, 25a. The closed position of the folding door 1 is shown in FIG.
  • the driver 25a carries the pull wedge 26a, which is guided through a recess in the carrier 8 and at the end protrudes from a guide channel which contains a sliding surface 36.
  • the two arms 28, 29 are with their wedge surfaces 30, 31 only in loose or no contact with the associated sliding surface 36, 37 which is on the carrier 8 or on the inner surface 24 of the wings 2b, 3a or in the direction of the above Guide part of the driver, on which the respective pull wedge 26 or 26a is not fastened, of the pair of door leaves 3 are present.
  • the wing 3a is pivoted by hand about the hinge axis of the hinges 17.
  • the driver 25a likewise measures a swivel path and, after measuring the play of the elongated hole in the driver, acts by pulling on the pulling wedge 26a via the swivel pin 33.
  • This is drawn with its arms 28, 29 located at the other end into the gap between the inner surface 24 of the wing 2b or the sliding surface 37 of the driver 25 and the sliding surface 36 of the carrier 8.
  • its wedge surfaces 30, 31 are supported on the inner surface 24 or the sliding surfaces 37, 36 of the door leaf 2b or driver 25 and carrier 8, so that on the leaf 2b a force in the sense of pivoting into the open position about the hinge axis of the Hinges 17 is exercised.
  • This Swiveling facilitates the further unfolding of the adjoining wing 2a and following, so that the front surface can be opened.
  • the operator would exert pressure on the wing 2b in the position shown in FIG. 5 when the position was partially open, this would not result in damage or tearing out of the hinges 17 because the wedge surfaces 30, 31 were components of one another are spaced arms 28, 29 which can spring towards each other under pressure.
  • a tensile force is exerted on the pulling wedge 26 via the driver 25, which engages on the one hand on the stationary sliding surface 36 with its wedge surface 30 and on the other hand on the sliding surface 37 or Inner surface 24 of the wing 3a and exerts a force in the opening direction on this wing.
  • the resilient arms 28, 29 help to pull the wings back into the position in which they are in a plane once a certain position has been reached.
  • the invention can also be applied to folding doors with more than two pairs of wings, a moment progressively being exerted in the opening direction when unfolding on the wing doors of the following adjacent wing pairs.
