Definitions

  • the present invention relates to a system for locking a slat in a shutter, and to a shutter assembled using said system.
  • a shutter with fixed slats comprises a plurality of slats blocked on two parallel lateral uprights that serve as supporting shoulders.
  • Each slat is generally obtained by cutting to size an aluminum extruded painted bar (e.g. 6 meters) whose cross section is very often oval in shape (but can be of other shapes).
  • each lateral uprights are provided with through-openings in which are inserted the slats.
  • each of the two ends of each slat is inserted in a respective through opening obtained on a respective side upright.
  • each slat has a profile which substantially follows the shape of the edge of the respective through opening.
  • each through opening of a first side upright is as specular as possible to the corresponding opening obtained on the opposite upright. All this with the obvious purpose to ensure that the slats, in use, are as parallel to each other as possible.
  • the through openings in which the ends of the slats are inserted must allow a certain clearance so as to enable the installer to adjust the position in the space of the slats themselves to give them the correct parallelism.
  • the through openings in which the ends of the slats are inserted must perform, in addition, an effective clamping function of the same to prevent any of them to accidentally slip out from a respective through opening.
  • each through opening in addition to the usual oval shape, has two narrowing points of its edge.
  • the two narrowing points which are opposite to each other, performing a certain locking action on the respective slat, would prevent the unwanted slippage of the same.
  • the main purpose of the present invention is, therefore, to provide a system for locking a slat in a shutter which is free from the drawbacks described above and, at the same time, is easy and economical to produce.
  • Another object of the present invention is to provide a shutter whose assembly requires the use of said system.
  • a shutter is provided whose assembly requires the use of said system; shutter that is claimed in claim 6 or in any of the claims depending directly or indirectly on the above claim 6.
  • the system 100 comprising a through opening 30 obtained on a support structural bar 20 in which the slat 10 is inserted.
  • At least two portions 30A*, 30A** of the edge 30A of the through opening 30 are provided with protruding elements 40, 41 facing each other and suited to clamp the external surface 10A of the slat 10 once it has been inserted into the respective through opening 30.
  • At least one of the protruding elements 40, 41 is an elastic lamella.
  • both the protruding elements 40, 41 are elastic lamellae.
  • each pair of elastic lamellae 40, 41 which is located on the same edge 30A performs an elastic clamping action on one end of the relative slat 10.
  • each elastic lamella 40, 41 is inclined at an angle ( ⁇ ) with respect to a plane ( ⁇ ) perpendicular to a plane ( ⁇ ) on which a flat face 21 of the support structural bar 20 substantially lies.
  • the angle ( ⁇ ) ranges from 3° to 7°, and depends on the type of material with which the slats 10 and/or the support structural bar 20 are made.
  • angle ( ⁇ ) is 5°.
  • the edge 30A of the through opening 30 itself is slightly larger than the profile of the slat 10
  • the structural bar 20 comprises two ratchet gear 22, 23 that protrude from the flat face 21 itself from the same surface from which the abovementioned elastic lamellae 40, 41 protrude (see below).
  • the shutter 1000 (shown only partially in the cited figures 4, 5, 6 ) comprises a panel 50 which is also advantageously made with an aluminum profile.
  • Said panel 50 ( Figure 6 ) comprises a box-shaped body 51 from which a wall 52 protrudes.
  • the box-shaped body 51 provides, in turn, two wings 53 and 54, each wing 53, 54 being provided with a respective ledge 53A, 54A.
  • each ratchet gear 22, 23 engages the corresponding ledge 53A, 54A of the box-shaped body 51 in a click-in manner.
  • the panel 50 on the opposite side in which there are two wings 53, 54, provides reliefs 55A-55E that protrude from the box-shaped body 51 and from the wall 52. Said reliefs 55A-55E are used to receive and/or support door and/or window frames (not shown).
  • the present invention also relates to a shutter 1000 which comprises at least one innovative system 100 of the type previously described.
  • the shutter 1000 also comprises:
  • the assembly of the slats 10 on the shutter 1000 is as follows:
