Definitions

  • the present invention is in the field of mobile screen dimming devices, for example roller shutter type, designed to close openings in the walls of buildings. It relates in particular to the two main components of these devices, which guide on the one hand the movements of the screens and on the other hand the storage of at least a portion thereof. In essence, these are the lateral guide slides and the storage boxes, that is to say the closed spaces in which for example the shutter aprons can be partially or fully wound.
  • the chest delimits in practice a storage space generally comprises a box closed at its two axial ends by a side wall which can be removable and, in this case, for example consisting of a cheek fixed to the box.
  • a side wall which can be removable and, in this case, for example consisting of a cheek fixed to the box.
  • at least one of the side walls may be formed of a wall portion of the building, depending on the location of the opening to be closed, imposing in turn the positioning of the trunk of the concealment system.
  • the screen device is constituted, in the event of a roller shutter, a rolling apron in the vault storage space.
  • the trunk contains winding means / unwinding thereof, which can be controlled manually and / or automatically, via a motorization of a winding shaft.
  • One of the primary functions of such a screen is of course to block the passage of light rays, which may include several distinct qualitative levels of occultation, that is to say "filtering" of the light radiation. It can be to install a separation which eliminates any vision between two spaces, which imposes in this case a blocking of the light rays without particular requirements in terms of luminosity.
  • the purpose of the occultation may be to reduce as much as possible the luminous level in a room, if one of the objectives is to ensure the most complete darkness possible.
  • the storage compartments of the shutter placed differently compared to the racks and volume more successful, are not discussed.
  • the entrance slot of the apron in the trunk, or more generally of the shutter screen which is arranged at least partly outside the joinery for windows or doors equipped with shutters, can be seen as an opening for light rays even when the flap is completely closed.
  • An external gap exists indeed necessarily between the outer facade of the screen and the song of the slot facing this facade, that is to say in practice in front of the screen.
  • a similar gap exists between the inner face of the shutter screen and the song of the slot facing it, behind the screen.
  • the interior volume of the box is much more likely to trap incoming radiation because it has an additional face that closes almost completely the internal volume, legitimizing a priori a different approach. It actually has pairs of opposite surfaces, capable of producing additional non-existent reflections in a U-shaped volume.
  • the existing shutter devices which in practice allow external light to enter a building at almost all levels of interfacing between the shutter screen and the rest of the installation, result in degrading the power of occultation of the latter.
  • the invention overcomes this deficiency, and makes it possible to provide a range of devices with shutter screens which ensures a high degree of opacity, resulting in a total or almost total absence of light behind the screen device, if it is designed for this purpose, or at least to significantly limit light leaks at all levels of interaction between the shutter screen and its supports.
  • the invention concerns, as specified, a shutter device with a movable shutter type screen, with a boot constituting an interior storage volume of the screen comprising a box closed by lateral partitions with a slot of passage of the screen which develops parallel to the plane of the opening to be closed and the right of lateral guide slides of the screen, is such that at least one of inner faces of the walls of the box has a dark color capable of absorbing the light radiation penetrating through said slot.
  • each contact with a peripheral wall of the box there is absorption of the maximum spectrum of wavelengths of the incident ray.
  • the inner faces of the side walls may have the same dark color as the inner face or faces of the box.
  • the idea could be to transform the entire shutter box into a kind of dark room, to trap with maximum efficiency the light rays of the outside light.
  • the side slides which objectively constitute another source of light leakage, can also be treated in the context of the invention, always with the same general objective of light insulation.
  • These slides comprise in practice a guide channel of the lateral ends of the screen defined by walls facing and a wall forming the bottom. These walls together constitute an interior volume of which at least one of the internal faces may present a dark color, according to the invention, for the same purpose as above.
  • the slides may be provided such that at least the internal faces of their walls facing each other are provided with ridges parallel to their longitudinal axis. These streaks have the effect of effectively trapping the light rays by preventing the successive internal reflections progressing towards the bottom of the guide channels and then bypass the side edges of the shutter screens to finally cause the light to come out of the light. inside the screened space.
  • the inner face of the wall forming the bottom of the guide channel may also be provided with ridges parallel to the longitudinal axis of the slide, to complete the preceding device equipping the opposite faces of the rail constituting the slide.
  • these grooves may have a triangular section, which ensures that any reflections of the light rays are returned to the introduction slot aprons / screens in the guide channel.
  • occultation devices that are equipped with storage boxes and / or slides according to the invention therefore allow to reach a high degree of light insulation, the interior of the rooms being practically no longer touched by some "pollution" light when the screens are closed.
  • said dark color may result from a coating, which would then be provided to cover the predetermined internal faces, said coating being affixed in a uniform manner for example on at least one internal face of the interior volume of the trunk or the guide channel. a slide.
  • a coating may for example consist of a paint or a lacquer, the surfaces of which are covered during the manufacture of the trunk parts and the lateral guide slides, that is to say that it is an integrated step in the industrial manufacturing process. It may also consist of a film or an additional section secured to the selected surface (s).
  • a piece having a dark color at least on one of its internal faces may be provided to equip said interior volume.
  • the dark color results from the affixing of a complementary piece.
  • the dark color chosen may be black, since it is theoretically a shade that absorbs all wavelengths of visible radiation.
  • a matte black color is recommended to optimize the absorption.
  • the invention responds to the observation that there are gaps on either side of the screen, in the passage slot of the shutter apron at the entrance of the trunk or in the guide channels. backstage, an external gap in front of the screen and an internal gap behind it. There is therefore a possibility of passage of the ambient light radiation, which can easily enter the premises by walking inside the chests / guide channels, and cause inside a bright atmosphere certainly alleviated, but which does n ' is not always desired.
  • the box 1 of the storage box comprises a winding mechanism 2, very schematically constituted of a rotating central shaft driven in rotation by manual means or by motorized means for automatic control of winding operations / unwinding apron 3, that is to say operations of opening / closing the shutter.
  • the apron 3 is consisting of blades 4 pivoting relative to each other, whose ends are guided laterally in the wings (not shown, see below). figure 3 ) while traveling to open or close the shutter.
  • the component is represented, Figures 1 and 2 completely closed, that is to say that the apron 3 is completely unrolled. It is therefore in the situation in which the problem of light crossings that one seeks to suppress / attenuate arises mainly.
  • the radius R 'appearing the external light radiation undergoes a very different fate due to the implementation of the invention.
  • the reflected ray After the first reflection on the blade 4 'of an apron which is often light in color - and in practice never very dark because of the dominant aesthetic standards - at the entrance of the box, the reflected ray is directed towards the outer wall 5. It is entirely absorbed by the inner face thereof, because of the color it presents according to the invention, for example matt black. As the incident light beam is totally absorbed by the internal face of the wall 5, no further reflections are produced and there is no longer any light at the outlet of the casing 1, on the inner side Int.
  • slides 10 As shown. These slides 10 have facing faces 11, 12 and a bottom 13 forming a U-shaped guide channel for the side edges of the screen device, an apron 3 in the present example, which moves in these two lateral rails in which he slides. They are provided with striations 14. These are arranged parallel to the longitudinal axis of the wings, and are in this case triangular section. According to one possibility, they have a depth for example of the order of 1 mm.
  • the striated inner faces are preferably coated with a dark color layer, for example matte black.
  • a dark color layer for example matte black.
  • Other materials than paint or lacquer can be used to apply such a layer inside the slides, as well as the box 1 of the roller shutter box. It may be the securing of a complementary element, film or piece to be fixed inside.
  • the material can alternatively come directly from manufacture with dark interior faces.
