Definitions

  • the present invention relates to handling doors of the lifting curtain type, and more particularly the folding accordion doors, comprising a flexible curtain with horizontal reinforcing bars arranged at regular intervals, lifting straps attached to the lower bar passing through rings fixed at least on certain bars, and a motor element comprising a strap winding shaft disposed above the curtain.
  • the edges of the curtain and / or the ends of the reinforcing bars can move in slides formed in, or by lateral uprights which support an upper horizontal crosspiece on which the strap winding shaft is mounted, and possibly a electric motor and control members of this motor. It is known to provide between two adjacent bars a flexible and inextensible means in the general shape of a strip to limit the spacing of said two bars when the curtain goes into the closed position and does not hinder the approach of the adjacent bars during the raising of the curtain.
  • the present invention aims to solve this double problem.
  • the subject of the invention is therefore a reinforcement device for a curtain door which can be raised vertically and which can be folded into an accordion of the type comprising a flexible curtain with horizontal reinforcing bars arranged at regular intervals, lifting straps attached to the lower bar passing through guide rings fixed at least on certain bars, and a motor element comprising a strap winding shaft, flexible and inextensible means, generally in the form of a band, being arranged between each pair of adjacent bands to limit the spacing of the two bars of the pair, remarkable in particular in that all the bars have guide rings, through which the straps pass, and in that the inextensible means has a structure favoring its folding in a preferential direction, such as that opposite to the strap lifting.
  • the structure favors folding in one or more intermediate zones situated between two end zones, the upper end zone possibly being longer than the lower end zone, the end zones being relatively little foldable.
  • the inextensible means is made of molded plastic, and the end zones are formed with longitudinal ribs, while the intermediate zone with preferential direction folding is weakened by transverse grooves causing formation and l extension of the fold at the place and in the preferred preferential direction.
  • the structure can be smooth, but the element is molded in the shape of the desired fold so as to extend under the weight of the curtain to its maximum inextensible length and to return automatically when the opening at the desired folding position.
  • a flexible bar for example constituted by a metal wire wound like a coil spring.
  • FIG. 1 a curtain door of a conventional type.
  • a curtain 1 is reinforced by horizontal reinforcing bars 2 arranged at regular intervals.
  • Lifting straps 3 are fixed to the lower bar 2A and pass through rings 4 fixed to the other bars.
  • a motor element comprises a shaft 5 for winding the straps and a motor 6, in practice a electric motor, with a transmission 7.
  • Other elements such as limit switches, relays, etc. are classic and therefore not shown.
  • the ends of the bars, and possibly the edges of the curtain move in slides 8, 9 formed in, or constituted by, vertical lateral uprights.
  • the motor 6, 7 can also be placed on this crosspiece.
  • the curtain 1 is made of unreinforced flexible plastic, and the weight of the bars, with their inertia, can cause deformation and elongation of the curtain fabric.
  • Reinforcement straps 11, said to be equidistant, are provided for this, placed against the curtain and fixed to each bar.
  • the lower bar 2A When the shaft 5 winds the straps, the lower bar 2A is raised, and arriving at consecutive intervals at each successive bar, it drives one, then two, etc. all bars to the top.
  • the curtain 1 folds between the bars. If it folds on the opposite side to the lifting straps 2, the folds are formed well, the curtain fabric is not pinched and the bars, at the end of lifting, are placed against each other with a reduced bulk in top of the portico. But if, for example, a wind, or an air pressure, pushes the curtain against the lifting straps, the folding is bad.
  • the curtain fabric is pinched, deteriorates, and the bars at the end of lifting are separated by packages of poorly formed folds. It is to avoid this drawback that the present invention is provided.
  • all the bars 2 comprise, in line with each lifting strap 3, rings 4 in which pass said lifting straps and each element 11A of equidistance strap 11, between two adjacent bars, has a flexible, inextensible structure, favoring its folding in the direction opposite to the lifting strap, said equidistance strap element being fixed to the curtain fabric or placed on the same side as the lifting strap, the two ends of each element 11A being fixed to the two adjacent bars.
  • Each element may, for example, be a thin strip of preformed flexible spring steel, which easily becomes flat when the curtain is stretched vertically, and which curves in the desired direction when the bar below is raised. It can also be a strip of plastic molded into the shape of the desired fold.
  • the equidistance element shown is of molded plastic, for example polypropylene, polyurethane, polyvinyl chloride or the like. It has the general shape of a strip, the ends 11B, 11C of which are intended to be fixed to the adjacent bars, for example by means of suitable sleeves.
  • the part median 15, intended to form the fold or to orient it, has on one side (that which is placed forwards in FIG. 1) a smooth surface while the other side is formed with slots or grooves transverse 15A favoring the folding which brings the two ends down in FIG. 2.
  • the closing of the slots 15A prevents the strip from bending in the opposite direction.
  • the part can also be molded with a certain curvature or preformation, further facilitating folding in the right direction.
  • the end zones 16, 17 of the strip are stiffened by longitudinal grooves or ribs 16A, 17A, on one or two sides, to obtain a folding as shown in Figure 5, which shows in schematic section the curtain partially raised.
  • Figure 5 shows in schematic section the curtain partially raised.
  • FIGS. 3 and 4 Another example is shown in FIGS. 3 and 4.
  • a molded rubber blade 25 is reinforced on its faces by inextensible fibers, for example steel or rayon cables.
  • steel cables 26 are coated in rubber over the entire length of the strip.
  • cables 27 are arranged transversely (section BB in FIG. 4B) in the middle zone and clamped against each other so as to form an incompressible structure, while in the end zones (section AA) , the cables 28 are arranged longitudinally.
  • the end zones are thus quite rigid, while the middle zone can bend in the direction in which the edges are raised, but not in the other direction.
  • a flexible rebar 2A At the bottom of the curtain, there can be an additional small section with a flexible rebar 2A, not affected by the straps.
  • This bar can be constituted for example by a coil spring, a plastic profile, etc. It can serve as ballast, feeler bar, etc., while remaining flexible.
