  • the reintroduction means are for example constituted by two rollers which are arranged on either side of the band 19 so that during the opening or closing the shutter 1, these rollers push the ribbons 62 and 63 against each other to restore the link between the shutter 1 and the metal strip 19.
  • FIGS. 38 to 42 show the successive stages of the deformation of a compressible bead 21 with a triangular section, during the separation of the flap 1 of the clamps 20.
  • FIGS 43 to 47 show the successive steps of the deformation of a T-shaped side edge 9 and 10 during the separation of the flap 1 of the transmission means.

  • the clamps 20 and the bead 21 are made of a resilient material so as to be elastically deformable during the separation of the flap 1 of the transmission means.
  • the shutter 1 is preferably attached to an elastic manner to the transmission means.
  • the bead 21 is provided at the side edges 9 and 10 of the flap 1 and present on either side of the latter a face 69 and 70 which is inclined relative to the plane of the flap 1 in such a way as to form a wedge.

  • the clamps 20 slide on the faces 69 and 70 of the bead 1 without the flap 1 is separated from the clamps 20 if this force is not large enough to cause the separation of the clamps 20 of the flap 1.
  • Such a situation is represented by a pincer 20 in phantom. When this force no longer acts on the flap 1, the clamps 20 are guided by the faces 69 and 70 to the flap 1 and tend it.
  • a variant of the bead of the figure 55 is represented at the figure 56 .
  • the bead 21 also has two faces 69 and 70 inclined relative to the plane of the flap 1. These faces 69 and 70 are coated with an elastically compressible material 71, so that the flap 1 is still stretched when it is connected to the clamps 20 because of the elastic deformation of this material 20, which is for example formed by rubber.
  • a part of the clamps 20 is in the form of a spring 72 which can be elastically deformed in the direction of the arrow 73 so as to be able to tension the shutter 1.
  • the attachment means are not necessarily made of clamps. So in the figure 58 the flap 1 has at the side edges 9 and 10 a succession of small separate blocks 74, preferably connected in a flexible manner between them. These blocks 74 are, for example, formed by "meshes" of a traditional zipper.
  • Each of the guideways 7 and 8, as shown in FIG. figure 59 comprises two longitudinal sections 77 and 78 having a rectangular cross-section. These profiles are provided with flanges 75 and 76 extending on either side of the side edges 9 and 10 of the shutter 1. These flanges 75 and 76 are directed towards each other, so as to partially surround the small blocks 74.

  • the metal strip 19 is guided in a corresponding recess formed between the sections 77 and 78 and is driven by a toothed wheel 35, not shown in FIGS. Figures 58 and 59 .
  • a reintroduction system which is similar to that described in EP 0 272 733 , may be provided to reintroduce the blocks 74 in the guideways 7 and 8.
  • the figure 60 represents a closure device in which a single gear 35 is provided at one of the two guideways 7 or 8. For clarity of the figure, these guideways are not shown.
  • the shutter 1 is provided with a rigid plate 80 which extends over the entire width of the shutter 1 and which is fixedly connected to the metal strips 19 of each of the edges. 9 and 10 of the flap 1.
  • the figure 61 represents a locking system comprising two bars 81 and 82 which extend parallel to the guideways 7 and 8 and which can be moved in the direction of the arrows 83 between an unlocked position, represented by dashed lines, and a position locked shown in solid lines.
  • the bars 81 and 82 In the locked position, the bars 81 and 82 extend along the side edges 9 and 10 of the shutter 1, so that the clamps 20 are wedged between these bars 81 and 82 while preventing the bead 21 of the shutter 1 from separate clamps 20.
  • the bars 81 and 82 can be locked manually or automatically when the bay 3 is closed by the shutter 1.
  • the transmission means consist of a flexible band 86, such as for example a textile strap, provided with a succession of clamps 20 which can be attached to the side edges of a flap 1, not shown in FIGS. FIGS.
  • the strip 86 is driven, via the clamps 20, by a toothed wheel 35 which consists of two parallel pulleys 87 and 88 mounted, at a distance from each other, on a common axis of rotation 12 and provided with teeth 36.
  • the clamps 20 have two rigid plates 90 and 91 applied on either side against the flexible band 86 by means of rivets 89.
  • the plates 90 which are oriented towards the toothed wheel 35 are spaced apart from one another. a distance which is sufficient to allow the strip 86 to be bent against at least a part of the periphery of this toothed wheel 35.
  • the rigid pads 91 which are oriented towards the opposite side of the toothed wheel 35, abut freely against each other when the flexible band 86 is guided in straight guideways.
  • a thrust force on the flexible strip 86 in the direction of the arrow 92 by the rotation of the toothed wheel 35 to close a bay by the flap 1 which is fixed to the clamps 20.
  • edges 94 and 95 of the plates 91 extend between the pulleys 87 and 88 and are folded transversely relative to the plane of these plates. The lateral sides of the edges thus formed then bear against each other during the closure of the shutter 1.
  • the rigid pads 91 facing the opposite side of the gear 35, have a width which is greater than the distance between the pulleys 87 and 88 of the gear wheel 35, while the rigid pads 90 and the flexible band 86 have a width that is smaller than this distance.
  • these have at each corner a recess 93 in which the teeth 36 can mesh.
  • the clamps 20 may consist of a single rigid plate 91 which is fixed to the side of the flexible band 86 which is remote from the gear wheel 35.
  • stiffening bars and / or ballast could be incorporated in the flap.
  • the guideways 7 and 8 must not be completely straight and may be curved.
  • closure device according to the invention is not limited to doors with vertical guideways, but may also have horizontal guideways. In some cases, it is possible to provide only a horizontal guide path to the upper side of a bay, so that the flap is suspended from this guide path.
  • the shutter of the device can close from the bottom instead of from the top when the guideways extend vertically.
  • the attachment means can be of very different shapes. It is for example possible to provide forceps at the side edges of the flap rather than the metal strip.
  • the clamps can also be replaced by bands consisting of magnets.
  • the bead 21 is not necessarily continuous, but may, for example, consist of a succession of blocks.
  • the invention extends to any shutter device in which transmission means are provided in a detachable manner between the shutter and the guideways.
  • the transmission means do not necessarily include a metal strip; this band can indeed be made of any material, flexible or rigid, having sufficient strength.
