Definitions

  • the invention relates to the slide of a metal shutter with a solid apron, to close off and protect the opening of a building.
  • the invention relates to roll-up and vertical descent/rise curtains.
  • the invention will be more particularly described with regard to a slide of a metal curtain in the context of anticyclonic protection, without however being limited thereto.
  • This curtain comprises full metal slats which, in the closed position of the apron, are arranged angularly relative to each other according to a "wave" profile, the vertical slides for guiding and supporting the ends of the slats having a profile which does not is not straight but is sinuous.
  • the slides thus have a profile according to a sinusoid with curved lines, allowing during the descent of the slats that they follow this sinuous guide to impose on the slats an angular arrangement between them, each connection zone between two slats engaging in each concavity of the slides, giving the slats a blocking in a fixed position in a horizontal plane.
  • patent application ES2536594 also shows slides with a sinusoidal profile with curved lines also having the above drawbacks.
  • the object of the invention is therefore to overcome the aforementioned drawbacks by proposing a slide for a metal curtain which is efficient in terms of resistance in a plane transverse to the vertical apron, without friction, is easy to implement, and economical in terms of manufacturing costs. .
  • the invention also relates to the manufacture of the backstage allowing the production of such a curtain.
  • the metal shutter comprises an apron intended to be lowered or raised and formed of slats, preferably solid, assembled and articulated with respect to each other, and two opposite slides each provided with a continuous longitudinal opening for guiding and sliding and traversed by the distal ends of the slats, the opening comprising two opposite longitudinal edges, the profile of each of which has a profile with alternating hollow geometry intended to accommodate, in the closed position of the deck, the articulation zones of the slats in their folded state, the hollows of the two edges being staggered (or diagonally opposite two by two with respect to the longitudinal/vertical median plane of the opening), the curtain being characterized in that the longitudinal edges have a broken line profile of such that the alternating recesses of each longitudinal edge of the opening are formed by the alternation of converging inclined straight segments and diverging from the inside of the opening.
  • the opening makes it possible both to facilitate the descent and ascent of the slats without friction and tightening, and to impose, in the closed position of the apron, a sawtooth surface of the slats to ensure reinforced resistance to cyclonic winds.
  • this notched profile (with non-curved edges/flats) of the opening makes it possible to maintain the apron perfectly wedged laterally by, on the one hand, the support of the articulation zones in the angles of the notches, and on the other share the support of certain blades against one of the edges of the opening (on the inclined faces).
  • the inclined and converging straight segments of one of the longitudinal edges of the opening are intended to support one slat out of two of the apron.
  • the convergent and divergent segments are connected by straight segments in a direction parallel to the longitudinal direction of the opening, that is to say in a vertical direction in the mounted position of the slides.
  • the longitudinal edges of the opening each have a trapezoidal profile.
  • the small bases of the trapezoids on one edge are opposite the segments connecting two trapezoids on the opposite edge (the said connecting segments and the sides of the trapezoids associated with the connecting segments forming the hollows of the opening).
  • the curtain comprises an abutment surface arranged at the lower end of the longitudinal opening of each guide rail and against which the lower end slat of the apron is intended to rest to initiate the pivoting/folding of the slats of the apron.
  • This abutment surface provides the pivoting of the lower end slat of the apron, the pivoting of the following slats being imposed by the broken lines of the edges of the opening (that is to say by the profile of the alternation of the straight and inclined segments of the two edges of the opening).
  • the width of the opening of each slide is designed so that the slats can descend coplanar between the edges of the opening, in particular until the lower slat abuts against an end abutment surface bottom of the curtain.
  • the abutment surface is constituted by the lower end of one of the edges of the opening, which is extended in the direction of the other edge by crossing the opening.
  • the apron has its lower end slat which includes abutment means.
  • the curtain is in particular used as an anticyclonic closing curtain.
  • the invention also relates to a slide having the aforementioned characteristics of each slide of the slatted curtain of the invention.
  • the slide is made from a single flat profile which is cut longitudinally according to a broken line profile (in particular of the type trapezoidal) to provide two separate parts which are intended to be arranged apart and parallel to provide the longitudinal opening of the slide.
  • angles of inclination of the inclined segments with respect to the connecting segments are 45° in order to provide a folding of the slats of 45° and to give the apron optimum resistance.
  • the invention also relates to a method for implementing the closure of the curtain of the invention, characterized in that, when lowering the curtain, the slats descend in a coplanar manner in a vertical plane between the two longitudinal edges (the slats descend completely straight) until the lower end slat abuts against an abutment surface, and in that, continuing the descent, the abutment surface forces the slats to pivot progressively by alternating on the longitudinal edges with a broken line, imposing an angular bend on them.
  • the term “height”, the qualifiers “upper”, “lower”, “high” and “low” of an element of the curtain are used within the framework of a normal installation of the curtain, c that is to say relating to a vertical notion of descent and ascent of the curtain.
  • the rolling shutter 1 illustrated in the figure 1 comprises an apron 10 with vertical sliding, a tube 2 arranged horizontally in the upper part to roll up the apron, and a guide system 3 for lowering and raising the apron.
  • the guide system 3 is formed of two opposite slideways 30 arranged in uprights at each of the two respective ends of the tube 2, and only one of which is illustrated on the figures 1 and 2 .
  • the tube 2 is preferably fixed to each slide via a flange 20, itself fixed to the wall.
  • each slide 3 is fixed to a frame 21 of the concrete or metal type.
  • Each slide 30 has a longitudinal opening delimited by two profile parts 30A and 30B, which are preferably made transversely integral with a U-shaped profile 30C.
  • the metal deck 10 is made of metal blades 11 which are preferably solid.
  • the blades 11 extend transversely to the guide system 3 and are therefore arranged in the installed position of the apron in a horizontal direction.
  • the blades 11 have a profile which does not necessarily have to be specific.
  • the slats are of the known type sold commercially to form the slats of a metal curtain apron. They could be redesigned to further optimize resistance.
  • a blade 11 ( picture 2 ) comprises a core 12 which is preferably planar and two opposite longitudinal edges lower 13 and upper 14 which each comprise a winding 13A, 14A respectively, of opposite direction and whose open longitudinal concavities 13B, 14B face in opposite directions.
  • the blades 11 are connected to each other by being hinged by stapling.
  • the stapling of two consecutive blades is done in known manner by engagement of a winding 13A of a blade in the winding 14A of the other consecutive blade, the free end of each winding engaging in the open concavity of the other winding.
  • the blades 11 are intended to descend in a straight vertical manner and in a coplanar manner with respect to each other as illustrated in the figure 2 , 3 And 5 , and when the apron is in the completely lowered and closed position, they are arranged angularly relative to each other, in zigzag as illustrated in the figure 7 .
  • This arrangement of the blades 11 in order to provide for the apron 10 a surface according to a sawtooth profile, and not according to a totally flat surface considerably reinforces the resistance to the winds.
  • This final arrangement of the slats according to an angular alternation is due to the design of the slides 3.
  • this design of the slides advantageously provides a descent and ascent of the slats in a totally coplanar manner with each other, avoiding any friction and clamping.
  • the apron 10 has its lower end slat 11 which comprises abutment means 15.
  • the abutment means act as a flyweight fitted into this lower end slat slat to facilitate lowering and guiding.
  • the lower end slat may include a gasket.
  • the guide system 3 comprises two vertical slides 30 arranged at a distance corresponding to the length of the apron.
  • the slides 30 accommodate the distal ends of the slats 11 making it possible to guide the slats in sliding when the apron is lowered or raised, and to hold the lowered apron in position.
  • Each slide 30 has a continuous longitudinal opening 31 over the entire length/height of the slide, ensuring the passage through the slide of one of the lateral ends of the slats.
  • the opening 31 is notched; it has two opposite longitudinal edges 31A and 31B whose profile is a broken line, in particular at alternative geometry of vertical and inclined segments.
  • the edges 31A and 31B each have a cutout according to a trapezoidal profile.
  • Each edge 31A, 31B of the opening comprises an alternation of protruding shapes 32 projecting towards the inside of the opening and of recesses 33, the respective convexity and concavity of which are straight.
  • Each protruding form 32 of one edge faces a hollow 33 of the opposite edge.
  • the width of the opening is constant and adapted so that the apron 10 descends straight ( figure 2 ), that is to say that the blades 11 descend in a coplanar manner, between the alternations of the projecting shapes 32 and the hollows 33 of the two edges.
  • This width is also adapted according to the bending angle to be imposed between the slats in the completely closed position of the apron.
  • each longitudinal edge 31A, 31B of the opening 31 of a slide is an alternation of straight sides 34 and cut sides 35 diverging and converging with respect to the interior space of the opening, each cutaway 35 on either side of a right side 34 forming an acute angle with the right side.
  • the angle between a straight side and a cut side can be symmetrical or not.
  • the angle of the cut sides corresponds to the inclination which will be imposed between the slats 11 of the curtain in the completely lowered position of the apron 10.
  • the angle between a straight side and a cut side is preferably symmetrical and of the order of 45°, in order to provide a folding of the slats at 45° and to optimize the wind resistance of the apron. Note that this angle can vary more or less in relation to 45°.
  • one of the edges 31B of the opening 31 of each slide 3 ends at the lower end with an abutment surface 36 constituting a cutaway extending and converging towards the other edge 31A.
  • the cutaway 36 of extension or abutment surface crosses the width/space of the opening 31 to be in line with/opposite the abutment means 15 of the blade 11 at the lower end during the descent. of the apron 10.
  • This lower end abutment surface 36 is intended to initiate the folding of the lower end blade of the apron.
  • the apron 10 is being lowered. Due to the sufficient width of the opening 31, the blades 11, as the descent progresses, do not abut on any obstacle surface, allowing them to descend in a coplanar manner in a vertical plane between the two edges 31A and 31B.
  • every other 11 blade ( figure 9 ) is deposited by applying against the cut sides 35 of the edge 31A opposite to that provided with the lower abutment surface 36, while the other blades bent angularly and parallel to each other are housed centrally in the opening 31 by pressing their edges 13 and 14 articulated in the angles of intersection of the straight sections and cut from the hollows 33 of the opening ( figure 10 ). Each blade in place is blocked by the next one.
  • the opening it is done in the usual way by raising the slats without any friction or clamping on the edges of the opening, since the slats pivot in the opposite direction to recover straight.
  • the invention also relates to the manufacture of a slide 3.
  • the slide 3 at least the two parts 30A and 30B delimiting the opening 31 of the slide ( figure 1 ) are advantageously made from a single piece of metal which is cut.
  • the metal part is a flat part which is cut longitudinally and symmetrically along a broken line L, here of trapezoidal profile. At one of the distal ends of the part, the cutting line L extends to the corner of the part in order to produce the abutment surface 36.
