Definitions

  • the invention relates to a shading and / or occultation device with flexible membrane intended to cover a surface, in particular glazed, such as a veranda, a window or the like, comprising a tree on which is wound and from which takes place at least one flexible membrane, the end of which is made integral with a support profile.
  • the present invention will find its application to industrialists specializing in shading and / or blackout flexible membrane devices.
  • devices which, although not at all suitable for covering glass surfaces, such as the roof of a veranda, include a shaft, the ends of which are mounted in bearings secured to fixed supports, by example, against a wall.
  • a flexible membrane On this shaft is wound a flexible membrane, the end of which is made integral with a profile which is itself fixed on articulated arms with elastic return means in the unfolded position.
  • articulated arms the rear end of which is fixed, like the shaft, against the wall, extend, under the action of said elastic return means, progressively during the unwinding of the flexible membrane. They provide it. thus, maintaining tension according to a desired inclination above the surface to be protected from sunlight.
  • the winding and unwinding shaft is only supported at its ends. Also, it flexes under its own weight. However, due to this deformation, the flexible membrane cannot be wound, around the shaft in a regular manner. In addition, it is impossible to stretch it evenly after unwinding.
  • these devices comprise a shaft around which and on which the flexible membrane is wound and unwound.
  • This shaft is subjected to elastic return means ensuring its rotation in the direction corresponding to the winding of the flexible membrane. It is, moreover, fixed, by means of bearings, situated at its ends, on a support such as a wall or the like.
  • bearings situated at its ends, on a support such as a wall or the like.
  • the end of the membrane it is made integral with a profile whose lateral ends move in guide rails while cooperating with transmission means of the chain, belt, rope or the like type.
  • these transmission means describe a looped circuit and are wound, on the one hand, around a deflection pulley or the like placed at the lower end of the guide rails and, on the other hand, around a pulley or driving wheel capable of being rotated by motorized or non-motorized control means.
  • This shading and / or blackout device is very complex due to the transmission means arranged in the lateral guide rails.
  • these guide rails must necessarily be fixed on supports such as profiles used in the composition of the structure of a veranda or constituting the uprights of a window.
  • the present invention aims to remedy all of these drawbacks, including those related to a shading and / or blackout device of the blind type.
  • the invention as characterized in the claims. solves this problem and consists of a shading and / or occultation device with flexible membrane intended to cover a surface, in particular glazed, said flexible membrane having one end secured to a support profile and winding around and unwinding from a winding shaft, said support profile being fixedly mounted on a support such as a wall while the winding shaft being movable and made integral, by means of suitable connecting means, with the free end at least two articulated arms with elastic return in the unfolded position, these arms themselves being mounted articulated, at their rear end, on a fixed base situated substantially at the height of said support profile to which the end of the flexible membrane.
  • the total weight of the winding shaft rests on the structure of the latter so that the device cannot start beating in the event of wind, as occurs with stores.
  • the present invention relates to a shading and / or blackout device 1 with flexible membrane 2 in particular intended to cover a glazed surface 3, such as a veranda, a window or the like.
  • this device 1 comprises a winding shaft 4 on which and from which the flexible membrane 2 is wound and unwound, the end 5 of which is made integral with a support profile 6.
  • this support profile 6 is fixed, while the winding shaft 4 moves in front of or above the glass surface 3 to be covered during the deployment and folding of the flexible membrane 2.
  • extension means 9 which, according to the invention, are present, substantially, in the form of at least two arms 10, 11, articulated with elastic return in the unfolded position.
  • these arms 10, 11 are able to push the winding shaft 4 above the surface to be covered 3 during the deployment of the flexible membrane 2.
  • the rear end 12 of these arms 10, 11 is mounted articulated on a fixed base 13 situated substantially at the height of the support profile 6 to which the end 5 of the flexible membrane is made integral 2.
  • the other free end 14 of these arms 10, 11 is, for its part, connected to the winding shaft 4 by means of suitable connecting means 15.
  • these connecting means 15 are in the form of a profile 16 extending substantially parallel above the winding shaft 4. Furthermore, this profile 16 is equipped, at its ends 17, 18, with bearing supports 19 at which the winding shaft 4 is rotatably mounted.
  • brackets 20 On this profile 16 are also mounted brackets 20 also visible in FIG. 2, equipped with rolling means 8 in the form of rollers or rollers with an axis of rotation parallel to the axis of the winding shaft 4.
  • the consoles 20 using the configuration of cradles partially enveloping the winding shaft 4. Inside these consoles 20, in the form of cradles, can thus rest this winding shaft 4 while preventing it from bending under its own weight in the case of a horizontal or inclined arrangement.
  • the peripheral speed of the rollers or rollers, constituting the rolling means 8 is necessarily identical to the peripheral speed of the winding shaft 4 so that it can rest on said rollers or rollers. This avoids the friction which is the cause of premature wear of the flexible membrane 2.
  • the articulated arms 10, 11 do not unfold in a linear fashion , but form a bend substantially at the height of the intermediate articulation 21.
  • the two parts 22, 23 connected by said intermediate articulation 21 and forming an arm 10, 11 are substantially juxtaposed and are located in the same plan.
  • the articulation means 24 by means of which the rear end 12 of the articulated arms 10, 11 is connected to the fixed base 13, are determined so as to allow pivoting of said articulated arms 10, 11 around an axis 25 perpendicular to their longitudinal axis and around a substantially horizontal axis 26.
  • FIG. 1 an embodiment of the present invention is illustrated according to which the articulated arms 10, 11 extend above the flexible membrane 2. It is understood that it is entirely makes it possible to arrange these articulated arms 10, 11 under the flexible membrane 2. In fact, it suffices, at this time, that the bases 13 are are located under the support profile 6 and that the profile 16 is disposed at the front of the winding shaft 4, under the flexible membrane 2 instead of extending, as shown in Figures 1 and 2, parallel to the above this winding shaft 4.
  • the rotation of the winding shaft 4 can be controlled by a tubular motor 7 placed inside.
  • the supply of this motor 7 is preferably carried out by a supply cable 27 housed in one of the articulated arms 11.
  • the flexible membrane 2 comes from a fabric whose width is necessarily limited. Also, for large area coverage, it is usual to juxtapose several sections of fabric, the seams or welds extending parallel to the direction of deployment of the flexible membrane. However, such welds or seams necessarily generate local extra thicknesses on the winding shaft 4 when said flexible membrane is gradually wound around the latter. However, it is obvious that such local excess thicknesses hinder, here again, a suitable winding of the flexible membrane. Also and according to the invention, said flexible membrane 2 consists of one or more sections of juxtaposed fabrics welded or sewn together transversely in the direction of deployment of said flexible membrane 2, ie parallel to the winding shaft 4.
  • such a device according to the invention avoids any lateral guidance of the flexible membrane. Indeed, the squaring of the assembly is ensured by means of the latter maintained constantly in tension.
  • such a device according to the invention is not very sensitive to wind, in particular in the case of an inclined or horizontal arrangement insofar as the total weight of the winding shaft 4 rests on the bearing structure, for example the structure of a veranda.
