Definitions

  • the invention relates to roller shutters for openings and more particularly with a roller shutter for closing windows of a building, with openings for the passage of air and light that can be sealed by adjusting the operating height of the blind without the need for special mechanisms It could also be used to protect against theft access or windows of a building.
  • Roller blinds formed with connected louvers articulated to each other are known to form a panel of blind slats, sliding between lateral guides, which can be wound and unwound in a winding drum housed in an upper drawer in the structure to open and close the opening in which the blind is arranged.
  • the slats of these blinds are blind and do not allow the passage of light and air through them.
  • Venetian blinds whose slats can be regulated angularly to allow the passage of air and light, although the regulation and closing and opening operations of the opening are carried out by different mechanisms, which is annoying.
  • rolling shutters formed with louvers provided with openings that can be sealed by oscillating wings arranged between two adjacent slats and in which the closing and opening of the openings is controlled by simple adjustment of the operating height are also collected. of the blind without the need to use special auxiliary tools or mechanisms.
  • US3642050 is known as a closure formed by a panel of sliding shutter slats between lateral guides and each slat formed with openings that can be closed by oscillating wings, which rest on the slat whose opening must close and also articulate with the Immediately upper blind slat through hook-shaped end portions, so that when the blind slat panel is unwound from the roller on which it rolls or unrolls, its descent and more specifically that of the adjacent upper slats affects the articulation with the extreme portions of the oscillating wings acting as a control lever for the angular positions of the wings forcing them to rotate on their supports so that the openings of the slats allow the passage of air and light. With the winding of the louver panel, the wings reverse the direction of their rotation to close the openings.
  • US 3989084 shows a sliding louver panel between lateral guides and in which at least a series of the louvers can oscillate to open or close an opening.
  • the slats partially overlap between the guides, include end pins for guidance and are connected by side links that, on the same side of the panel, connect the pin of an upper blade with an intermediate point of the lower blade above its pin so that the slats can be rotatably open towards the outside with the descent of the links.
  • each slat includes damping strips for contact noise between the slats.
  • WO2006037594 shows a panel of blind slats with openings that can be closed by oscillating wings provided with a first and a second hook for the respective articulated joint to the lower hook of an upper adjacent slat and the upper hook of a lower adjacent slat.
  • the swinging wings also connect two adjacent slats.
  • the tilt is forced on the upper hooks of the adjacent lower slats so that the openings of the slats allow the passage of air and light.
  • the wings reverse the direction of their tilting to close the openings.
  • WO2010082227 describes a panel of blind slats, sliding in a pair of vertical guides, with oscillating wings that relate two adjacent slats in the panel.
  • the slats are formed with frames constructed with lateral supports, crossed by bolts between which the oscillating wings that will open or close the opening of the frame are arranged, connected by lower profiles that limit the route of the oscillating wings and are formed with shaped sections of hook for the connection with corresponding upper sections provided on the swinging wings in the respective adjacent lower slats, so that the hook-shaped sections are forced to support the weight of the blind panel, which can lead to deformations and warping not wanted.
  • the formation of the blind panel is complex and requires multiple components for its formation: plugs with protrusions for insertion into the cavities of the end hooks of the lower profiles and for the elements profiles that give body to the support and include adjustment sections for the lower profiles and through holes for the bolts that must be connected to the wings to allow their oscillation. Bolts must finally be secured by nuts.
