Definitions

  • the invention relates to a roller door with side guide rails and a preferably manually operated door leaf, which is guided in the guide rails between an open and a closed position, wherein between the end area of the door leaf and the end edge region facing away from the end edge of the door leaf or the door opening to be closed with the door leaf the like at least one catching device or the like is arranged over a remaining path of the door leaf during its transition into the open position.
  • Such a roller door is known for example from EP 0 362 585 B1.
  • This is a roller door in a basically known configuration with guide rails or guide profiles, in which the side edges of the door leaf are slidably guided between the closed position and the open position.
  • Such door leaves are usually rolled up and down on rollers, but they can also be moved to a different position when changing to the open position.
  • efforts are made to make the door leaves lightweight in order to keep the force required for the movement process small.
  • door leaves made of profiles which follow one another in the direction of movement come into consideration, for example made of aluminum or else so-called curtains made of continuous, corresponding, flexible Foils and the like.
  • the roller door In order to enable high accelerations and decelerations with such a door leaf without the closing area of the door leaf moving irregularly with respect to the other door leaf area, the roller door according to EP 0 362 585 B1 provides a catching device which consists of at least one spring attached to a guide rail and there is a roller arranged at the end edge region of the door leaf, which runs onto the spring when the door leaf is moved into the open position, so that the door leaf is spring-loaded in its open position. The forces transmitted from the door leaf to the spring are introduced into the guide rail.
  • the invention has for its object to provide a roller door, in particular for manual operation, in which occurring forces and torques are essentially not introduced into the guide rail when the door leaf is transferred to its open position.
  • the catching device designed as a spring is supported on a console which is attached directly or indirectly to the building and with a holder for a winding shaft of the door leaf or a device for arranging the door leaf in a position deviating from the closed position.
  • the advantage of the roller door designed according to the invention is that the forces transmitted when the door leaf reaches the open position are not introduced into the guide rail, but into the console, which is attached to the wall of the building and on which the holder for the winding shaft or another device for the arrangement of the door leaf is arranged in a position other than the closed position, from which forces of the door leaf braked in the open position are also transmitted and derived into the masonry without any forces acting on the guide rail. It has been shown that this arrangement of the catching device on the console together with the holder, in particular the winding shaft, has a positive influence on the forces occurring when the door leaf moves, in particular when the end position is reached, with the associated interception of the door leaf.
  • the console and the holder are formed in one piece.
  • the bracket consists of a tube section of rectangular cross section, preferably square, on which plate-shaped fastening elements are arranged, preferably welded on. The bracket is screwed to the masonry using the plate-shaped fastening elements.
  • the holder for the winding shaft preferably consists of two crossbeams which are arranged at a distance from one another are parallel and are connected to each other at their free end.
  • the winding shaft is slidably guided between these traverses, so that the winding shaft can move in accordance with the already wound door leaf in such a way that the door leaf always runs vertically into the guide rails and does not have to be bent in this area. This enables the door leaf to be opened and closed smoothly, which is particularly advantageous in the case of manually operated door leaves.
  • the bracket extends at an angle of in particular 45 ° to the longitudinal axis of the console, so that a downward force is generated which presses the winding shaft with the wound door leaf in the direction of the guide rails, thereby supporting the closing process of the roller shutter.
  • the spring is designed as a helical spring and is supported at one end on the console and protrudes with its second end into the movement area of the door leaf, where it also moves with the door leaf moved into the open position a stop cooperates, which is arranged in the end edge region of the door leaf.
  • the coil spring has an angled arm at its end facing the console, which engages in a corresponding bore in the console, so that the forces introduced via the coil spring by the door leaf moving into the open position are introduced directly into the console.
  • the stop is designed as a roller and the free end of the spring is curved in accordance with the circumference of the roller. This has the particular advantage that the stop is reliably picked up and braked by the catch element when it reaches its end position in the open position of the door leaf.
  • FIG. 1 A part of a roller shutter is shown in FIG.
  • the roller door has a guide rail 1 on both sides, which is fastened vertically to a masonry not shown in FIG. 1, preferably screwed on.
  • a door leaf 2 In the guide rails, of which only one guide rail 1 is shown in FIG. 1, a door leaf 2 is guided, the side edges of the door leaf 2 engaging in the guide rails 1.
  • the door leaf 2 can be designed in a manner known per se as a construction consisting of a plurality of panels or as a curtain.
  • the door leaf 2 can be moved back and forth along the guide rails 1 between an open position and a closed position, the movement being carried out manually.
  • the door leaf 2 If the door leaf 2 is transferred from its closed position into the open position, the door leaf 2 is wound on a winding shaft 3, this winding shaft 3 being supported against the masonry by torsion springs, so that the torsion springs, which are not shown in FIG Support upward movement of the door leaf 2, d. H. relaxed during the upward movement of the door leaf 2 and tensioned during the downward movement of the door leaf 2.
  • the winding shaft 3 is mounted in a holder 4.
  • the holder 4 consists of two parallel traverses 5, which are designed as tubular sections of rectangular cross section.
  • the cross members 5 are welded to a bracket 6 at an angle of 45 ° to the longitudinal axis of the guide rail 1 which is U-shaped in cross section.
  • the trusses 5 enter at its free ends arranged limiting element 7 which is welded to the cross members 5.
  • the winding shaft 3 is fixed according to Figure 2 via a U-shaped bracket 8 and two screwed on its ends U-shaped guide elements 9 to the cross members 5 such that the winding shaft 3 according to the diameter of the wound door leaf 2 along the cross members 5 in the Type is guided movably that the door leaf 2 runs vertically into the guide rail 1 regardless of the extent of the wound door leaf 2, so that kinking of the door leaf 2 in the region of the upper end of the guide rail 1 facing the winding shaft 3 is avoided.
  • the U-shaped bracket 8 engages around the winding shaft 3 and is inserted between the two parallel cross members 5 of the holder 4. At its ends reaching through between the two cross members 5, the U-shaped bracket 8 has a thread. About these ends of the U-shaped bracket 8, the guide elements 9 are attached and secured with nuts 10 on the U-shaped bracket 8 that the U-shaped guide elements 9 overlap both parallel cross members 5 and with the inner surfaces of their free legs to the Fit the outer surfaces of the crossbeams 5. The winding shaft 3 is thus displaceable along the crossbeams 5.
  • the console 6 consists of a raw section of rectangular cross section, on the outer surface of which an L-shaped bracket 11 is welded. Furthermore, two plate-shaped fastening elements 12 and 13 are welded to the bracket 6, with which the bracket 6 can be fastened to the masonry 14 shown in FIG. 2 via corresponding bolts 15. For this purpose, the fastening plates 12 and 13 each have a bore 16 or 17, through which the bolts 15 can be inserted.
  • console 6 there is also another in the region of the tube section which is rectangular in cross section Bore 18 arranged, the function of which will be explained below.
  • a catching device is arranged over a remaining path of the door leaf 2 during its transition into the open position, which consists of a spring 19 and a spring roller 20 attached to the door leaf 2.
  • the spring 19 is shown in detail in FIGS. 5 and 6 and consists of a spring steel which is circular in cross section and which is wound in the form of a coil 21 in its central region.
  • One end 22 of the spring 19 is formed in the shape of a circular arc in such a way that the inner radius of the end 22 of the spring 19 in the shape of a circular arc corresponds to the outer diameter of a circumferential annular groove in the roller 20.
  • the opposite second end 23 of the spring 19 is angled at such a right angle that it runs parallel to the longitudinal axis of the coil 21.
  • the spring 19 is fastened to the angle 11 by means of a fastening element 24 shown in FIGS. 7 and 8.
  • the fastening element 24 is U-shaped in cross section, the two legs 25 being bent outwards at their free ends.
  • the fastening element 24 is thus essentially pot-shaped and has in its base 26 a bore 27 through which a bolt can be inserted, which extends through a bore 28 in the free leg of the angle 11, so that the fastening element 24 is screwed to the angle 11 .
  • the fastening element 24 extends through the helix 21 of the spring 19 in such a way that the spring 19 is held between the bent ends of the legs 25 of the fastening element 24 and the angle 11.
  • the end 22 of the spring 19 protrudes into the movement space of the door leaf 2 such that the roller 20 arranged on the door leaf 2 runs into the region of the spring 19 in the form of an arcuate section when the opening points are reached and is resiliently intercepted via the helix 21.
  • the second end 23 of the spring 19 is inserted into the bore 18 of the bracket 6, so that the forces transmitted from the upward moving door leaf 2 to the spring 19 are transmitted to the bracket 6 via the second end 23 of the spring 19. These forces are then introduced from the console 6 into the masonry 14 via the bolts 15.
  • the roller door described above has the particular advantage that the forces occurring when braking the upward movement of the door leaf 2 via the catching device, consisting of the spring 19 and the roller 20, are introduced directly into the console 6 and thus into the masonry 14, the Console 6 is advantageously connected directly to the holder 4, via which the reaction forces of the door leaf which is wound on the winding shaft 3 are likewise introduced into the masonry 14, the different forces not being introduced into the guide rails 1 in particular.
