Definitions

  • the object of this innovation is a shutter with the special feature of having adjustable louvers rotating along the horizontal axis which collaborate with mechanisms that ensure perfect closure to penetration by light.
  • shutters are composed of a series of louvers or fins placed crosswise to a frame and inclined with respect to it.
  • louvers for shutters are installed on their frame in both fixed and adjustable manners Adjustable louvers, contrary to fixed louvers which are blocked on the frame in a predetermined inclination, make it possible for the user to adjust the inclination of the louvers on their horizontal axis in a combined manner because their ends are mounted on the frame by means of pins that allow them to rotate, using a lever hinged inside each of them.
  • the adjustable louvers made according to currently known technology which offer the great advantage of being able to adjust the intensity penetration by exterior light, have the problem that they cannot ensure perfect closure to light because light can filter in through lateral cracks between louvers and the frame as well as between the horizontal cracks between one louver and another.
  • the US patent US-A-4509290 discloses a shutter construction provided with a plurality of louvers whose closed position provides for the block of light and air passage thanks to the fact that the ribs and the grooves positioned on the louvers, interlock with one another.
  • the object of this innovation is to eleiminate the aforementioned problems by use of suitable means that guarantee total closure to light of the shutter with adjustable louvers when this is being closed, acting on all those critical zones where infiltration by light can take place.
  • variable louver shutter according to this innovation which basically consists of frame 2, made by joining the profiled ends of four slats of wood or metal or similar materials and a series of adjustable fins or louvers 3.
  • Louvers 3 consist of elongated slats placed parallel one over the other in a specific inclination and which are hinged, at their ends, to two vertical jambs 4 of the frame using elastic pins 5.
  • louvers can be applied, according to the case, both in the mid part of the two end sides of each louver, as in figure 1, and in the lower part of the sides.
  • the louvers rotate symmetrically with respect to their center of rotation.
  • they perform a rocking motion with the part facing up rotating along an axis positioned along the lower side.
  • the special feature of the innovation consists in having provided mechanisms that prevent infiltration of light between louvers 3 and the frame structure to guarantee perfect exclusion of light by the shutter when the louvers are in their closed position.
  • the means that allow achievement of these results consist both of special longitudinal grooves 6 machined on the upper exterior and lower interior side of each louver, that allow a jointed horizontal coupling between each louver and the adjacent louver, and of two profiled sections 7 which can be positioned between the inner sides of the two frame jambs and the most external lateral sector of louvers 3.
  • the two profiled sections 7, which are used to synchronize rotating motion by the louvers because they are hinged to the upper side sectors of the louvers by jointed elements 20 which engage with pins 21 fastened to the upper edge of each louver, have two parallel strips facing the inside and where the interior coupling section extends laterally with wing 8 that overlaps the inner edge of the jamb.
  • Another section 9 is applied in the two parallel strips and constitutes the connection element with the adjustable louvers.
  • Sections 7 and 9 can also be made of different materials, one for example in wood and the other in metal or vice-versa, or out of the same material.
  • section 9 can also be eliminated since its internal profile, made to block joint elements 20, can also be machined in section 7.
  • One of the two profiled sections also connects with an operating mechanism, not illustrated, which could, for example, be the lever type and which allows the louvers to be closed and/or opened.
  • louvers in this case hinged at their lower edges, rest laterally on jambs 10 equipped with profiled extension 11, made with the same shape as the blades, against which the louvers themselves mesh and strike when they are closed.
  • the profiled extension can consist of a metal or wooden element applied to and fastened to jambs 10 or can be carved in the inner edge of the jamb itself.
  • the mechanism that allows the louvers to be opened and closed consists of section 12 positioned in the middle of the louvers.
  • adjustable louver shutter in question has been illustrated and described according to a preferential solution but several variants can be forecast, technically equivalent to the aforementioned parts and components, which solutions are to be held to be comprised in the extent of protection of the innovation as defined in the claims.
