Definitions

  • the present invention relates to a collapsible grille shutter unit to apply at a door or window opening to control the access in a desired way.
  • the invention relates to a method for the production of a such a grille shutter.
  • Such collapsible grille shutters comprise usually a plurality of metal vertical bars whose ends can slide by means of knobs in horizontal guides.
  • the vertical bars are interconnected by metal rods in a crossing arrangement (lazy tongs grilles) hinged to each other in the crossing point, having at their ends pins that slide in grooves made in the vertical bars same.
  • the vertical bars are brought from a starting position, where they are approached to each other and the metal rods are arranged substantially vertical, to a position where they are distanced corresponding to an oblique arrangement of the metal rods.
  • a further drawback is that the known methods for the production of the grille shutters provide many manual steps, and are expensive and complex because they require cutting many elements of different length.
  • the collapsible grille shutter unit comprising at least a first and a second bar which can move parallel towards/away from each other, a first plurality of hinged rods at the first bar and a second plurality of hinged rods at the second bar, the rods of the first and of the second plurality being in pairs hinged to each other at a movable end that is located between said two bars at a mid point, whereby said bars can approach/move away from each other with a consequent movement of said end.
  • each rod is hinged to the respective bar at its other end.
  • the ends hinged to the bar of at least two following rods along each bar have means for engaging with each other, suitable for causing a rotation of the two rods symmetric with respect to a plane perpendicular to the bar.
  • said means for engaging comprises a shaped surface with recesses and protrusions suitable for engaging with the respective protrusions and recesses of the shaped surface of another rod, in order to transmit a mutual rotation about said fixed pin.
  • each couple of rods hinged to each other at a movable end is interlaced with another couple of rods to form substantially an "x" so that respective parallel rods lay in a same plane.
  • This mechanism allows, furthermore, the collapsible grille shutter unit to shrink to a position of minimum encumbrance with rods approached to each other.
  • a modular collapsible grille shutter comprises a plurality of grille shutter units arranged in series as above defined connected to each other by said rods.
  • the bars are formed by two parallel slats and the rods, in the collapsed position of the grille shutter, disappear between said slats whereby the collapsed grille shutter has the same width as the sum of the widths of said bars.
  • the ends of said rods are hinged on pins arranged in a midpoint between said bars, so that when the grille shutter is collapsed said pins engage in a recess provided within said bars, or have height less than the distance between said slats.
  • the bars are formed by two profiles having longitudinal grooves that in use are opposite, said plurality of rods being hinged to said bars by means of support blocks that engage with said grooves.
  • a grille shutter comprises a plurality of units in succession that are arranged to form a plurality of intermediate bars set between a starting bar and an end bar, said rods hinged to said respective bars creating in a direction orthogonal to said rods at least two rows of rhombi such that said means for engaging with each other cause a symmetric opening movement of the rhombi.
  • At least one third row of couples of rods is provided suitable for forming a corresponding series of rhombi like "lazy tongs", suitable for assuring a fixed distance between two successive bars.
  • At least said starting bar or said end bar have said opposite grooved profiles united to each other in order to form a single profile, said starting bar allowing a snap-fit engagement with a starting profile anchorable to a wall, said end bar allowing a snap-fit engagement with a movable end profile suitable to house a lock.
  • a collapsible grille shutter unit comprises a first and a second bar 2a and 2b interconnected by a first and a second plurality of rods 3a and 3b hinged to each other at an end by a movable pin 5.
  • each rod 3a of the first series is hinged to the first bar 2a and each rod 3b of the second series is hinged to the second bar 2b by fixed pins 4.
  • Fixed pins 4 can be located at an end of rods 3a and 3b (figures 1-3) or at a midpoint thereof (figures 4 and 5).
  • a couple of hinged rods 3a and 3b can be, moreover, interlaced with another couple of hinged rods 3a' and 3b' in order to form substantially an "x" where the parallel rods 3a, 3b' and 3a', 3b lay in a same plane.
  • the "x" arrangement of the couples of rods 3a, 3b and 3a', 3b' as above described determines, furthermore, a position of maximum opening for bars 2a and 2b, since when the parallel rods 3a, 3b' and 3a', 3b contact each other, a self-blocking is obtained at the movable pin 5 that prevents a further moving of bars 2a and 2b away from each other.
  • each rod 3a hinged to the first bar 2a, is shaped in a way suitable to mesh with the complementary end of rod 3a' to it neighbouring.
  • each rod 3a, or 3b has a plurality of protrusions 7a, or 7b, and a plurality of recesses 8a, or 8b, arranged along a circumference, or a portion of circumference, suitable for engaging with each other (figure 12).
  • Such gearing allows, therefore, to operate in substantial synchronism all rods 3a and 3b of each couple of bars 2a and 2b of the device 1 and to provide a opening/closing mechanism with high precision.
  • FIG 13 a possible exemplary embodiment is shown of a modular collapsible grille shutter 10 obtained coupling to rods 3a and 3b a plurality of collapsible units 1 as above described.
  • all bars 2a and 2b of the grille shutter 10 with exclusion of the first and of the last, have at each fixed pin 4 two overlapped rods 3a and 3b that give continuity to the structure connecting two consecutive devices 1.
  • bars 2a and 2b can comprise two parallel slats 2a', 2a" and 2b', 2b".
  • rods 3a and 3b in the collapsed position of the grille shutter 10 can disappear between slats 2a', 2a" and 2b', 2b", since, both fixed pins 4 and the movable pins 5 have the same height as the sum of the thickness of the two rods to it hinged (figure 11).
  • movable pins 5 engage in a recess 11 made within bars 2a and 2b (figure 17). In both cases the collapsed grille shutter 10 has the same width as the sum of the widths of the bars and then a minimum encumbrance.
  • FIGS 18 and 19 a modular collapsible grille shutter 10 is shown applied to the inlet 51 of a shop 50 with bars 2a and 2b arranged horizontally and respectively in the extended configuration and in the collapsed configuration.
  • FIG 20 an exemplary embodiment is shown for grille shutter 10 alternative to that shown in figures from 1 to 13.
  • two rows of rods 103a and 103b are provided hinged to the respective bars 102a or 102b in order to form in an orthogonal direction to them at least two rows of rhombi 161.
  • Rods 103a and 103b, forming each rhomb 161 have at the respective ends protrusions and recesses, already described with reference in particular to figure 12, which mesh with each other for causing each rhomb 161 to open symmetrically.
  • At least a third row 162 is present of couples of rods 103a and 103b that form a corresponding series of rhombi like "lazy tongs", for assuring a same distance between successive bars.
  • bars 102a and 102b are formed by profiles 102a'-102a" and 102b'-102b" respectively having longitudinal grooves 112 that in use are opposite.
  • the series of rods 103a and 103b are hinged by means of pins 104 to bars 102a and 102b by means of support blocks 115 that engage with the grooves 112.
  • This solution allows to conceal pin 104 in bar 102a, or 102b, in order to impede any forcing from the outside increasing the safety of the invention.
  • movable pins 105 can comprise two halves 105' and 105" that fit with each other.
  • exemplary embodiments above described of the grille shutter 10 provide a succession of rods set between a starting bar and an end bar.
  • exemplary embodiments are shown having respectively a starting bar and a end bar in case of profiled bar. They have the opposite grooved profiles united to each other in order to form a single profile 122.
  • the starting profile 122 in operative conditions is fastened, for example snap-fitted, by a connection pin 130 to a starting profile 150 that in turn is fixed to a wall, for example by means of bolts, screws etc.
  • the end bar 122 can be snap-fitted to an end profile 155 suitable to house a lock 160 (figures 24 and 25).
