Definitions

  • Object of the present invention is a new embodiment of a roller shutter with swinging slats, which is an improvement of previous shutters object of the European Patent EP2398993 and of the Italian Patent Application BA2013A000061, whose content is incorporated in the present description.
  • roller shutters with swinging slats or lamellae there are known roller shutters with swinging slats or lamellae, as for example the ones described in the above cited patents.
  • an unsolved problem is represented by the slats inwards bending with consequent torsion of its elements and in particular of the coupling hook of the lower fixed profiles.
  • Such problem has been faced and solved by means of the cited inventions, by provision of intermediate supports (EP2398993) or by stiffening the slats in swinging step (BA2013A000061) , respectively.
  • aim of the present invention is to solve the problem of the torsion of the lower hook of the lower fixed profiles in shutters of great dimensions.
  • the present invention allows a reduction of elements with respect to the ones used for the inventions described in the cited patents; moreover, it allows to use the same elements for roller shutters with box arranged both inside and outside the house with consequent simplification of the shutter assembly and assembly times.
  • FIG. 1 shows the main elements of the slat: movable lamella, lower fixed profile and mono-wall support .
  • figure 2 shows two coupled slats, one thereof being rotated of 90° in counterclockwise direction.
  • FIG. 3 shows two coupled slats, one thereof being rotated of 90° in clockwise direction.
  • figure 4 shows a portion of roller shutter, rolled in a box arranged inside the house.
  • figure 5 shows a portion of roller shutter, rolled in a box arranged outside the house.
  • FIG. 6 shows an exploded view of a slat with two intermediate supports in which it is possible to note the fixing systems of the supports with the spring elements and the particulars of the intermediate and side supports;
  • - figure 7 shows an exploded view of a slat with the sole side supports
  • - figure 8 shows an exploded view of a slat with the intermediate supports introduced in the same
  • FIG. 10 shows a side section of the movable lamella while opening, and in particular a side section of the lower fixed profile
  • FIG. 11 shows a side section of the movable lamella while closing, with the spring element and the gasket
  • FIG. 13 shows the whole shutter with opened slats without intermediate supports
  • FIG. 14 shows the whole shutter with closed slats with intermediate supports.
  • Object of the present invention is a roller shutter with whole movable lamella swinging slats (figs. 13-14).
  • Each slat 30, 30a (figs. 6, 7 and 8) is made up of a fixed frame 40, 40a and of a removable swinging fin 1.
  • said fixed frame is formed by many elements: two or more supports 2 and 2a, a fixed lower profile 3 and plugs 5a and 5c, two alternative gaskets 6 or 6a.
  • the slat 30 is formed by a fixed frame 40 (having a couple of supports 2) and by a movable lamella 1.
  • the slat 30 is provided with a straight section, without right or left convexity, as in the cited patents.
  • the swinging movable lamella 1 is not subjected to interruptions any more because the intermediate supports 2 and 2a are arranged behind the same, and therefore the same does not represent a sole swinging movable fin.
  • the side supports 2 do not rotate any more around a pin 4 as in the cited patents, and therefore they are not provided with a through hole 7 any more, on the contrary in the lower part they have a projection 8 of such shape to allow the coupling with the lower fixed profile 3 (fig. 1) .
  • the removable swinging lamella 1 (figs. 1, 2 and 3) in the upper portion is provided with a hook 14 and a recess, for example a hole 15, outside the same.
  • the hook 14 of the lamella 1 is coupled with the hook 10 of the lower fixed profile 3, thus allowing a rotation of the lamella 1 of 180° and not of 90°, as in the cited patents, thus allowing to provide a roller shutter with box arranged both inside and outside the house using the same elements (figs. 4 and 5) .
  • the recess 15 receives the projection with circular section 4a of the supports 2 and 2a and does not receive the rotation axis 4 any more, as in the previous patents, and its opening faces always to the inner side of the roller shutter.
  • the walls of the supports, the side one 2 and the intermediate one 2a, are shaped in according to the inner projection of the movable lamella 1.
  • the lower portion of the supports 2 and 2a, as in the previous versions, is provided with a projection 8 which engages the recess 9 of the fixed profile 3 and in order to avoid the shift of the side support 2 along the recess 9 it is used the plug 5a (fig. 6) .
  • the plugs 5b are no more needed because now the movable lamella 1 is entire.
  • the intermediate support 2a has the same shape of the side support 2. As in the previous version, it has the function to stiffen the slat in the intermediate portion and since it is arranged behind the movable lamella 1 it does not interrupt it and this gives more rigidity to the slat by avoiding the contained bending in the horizontal plane .
  • the supports 2 and 2a can be obtained by cutting an extruded structural in aluminum, by pressure die- casting of light alloys or by forging of sheets. In order to avoid the support 2a shifting along the recess 9 it is possible to introduce a spring element 25 inside the recess of the hole 15 of the movable lamella 1, owing to friction such element constraints the intermediate support 2 and 2a in the optimal position.
  • the intermediate support 2a can be constrained using two of these elements 25 or only one 25 introduced in the intermediate recess of the upper wall 25a of the intermediate support 2a obtained by removing material (fig. 6) . For the side support 2 it is enough the usage of only one spring element 25, the other end is blocked by the plugs 5a.
  • a projection 26 mechanically, directly from the fixed profile 3 which blocks the supports 2 and 2a (fig. 9) .
  • it can be limited the sliding of the side supports 2 with a projection 5d which engages a hole 27 of any shape obtained on the vertical wall of the support 2 and by a bearing one 5e (fig. 6) -
  • the supports 2 and 2a can be both obtained by pieces of extruded profiles and by molded pieces of various materials, as for example aluminum alloys or the like.
  • the fixed lower profile 3 (fig. 3) has the following basic features:
  • the lower portion 10 allows the upper portion 11 of the swinging fin 1 to be coupled and to rotate without unhooking;
  • the two supports 2, the lower profile 3, the movable lamella 1 as a whole represent the classic functioning of a little projecting fin (fig. 2) . Since the hook 14 of the movable lamella 1 can be coupled to the lower fixed profile 3, the weight of the lower profile 3 of the upper slat acts as a lever and causes the movable lamella 1, belonging to the lower next slat, to rotate without the use of mechanisms (gears, chains or the same) ; on the contrary in pulling step, the weight of the underlying profiles closes, by squeezing, the lower portion of the lamella 1 towards the gasket 6. As an alternative to the gasket 6 of the lower fixed profile 3, the movable lamella 1 can be provided with a gasket 6a in the inner portion of the lamella 1 in order to deaden the noise in falling step .
  • the movable lamella 1 is provided with blocking teeth 11a, lib and 11c (figs. 1 and 10), the tooth 11c being now vertical instead of horizontal as in the cited patents.
  • the arrangement of the invention for example the assembly of slats made up of a fixed portion and a movable one, which make up together the screen of the shutter, the shutter by sliding in suitable guides 13 protects, aerates or closes hermetically the openings of the windows.
  • the up and down rolling of the shutter screen around the roll can be manual or motorized.
  • the opening of the movable portions of the slats part of the invention is obtained by the transmission of the weight force of the upper slats on the lower ones by means of a lever, obtained purposely by offsetting the position of the upper portion 11, 14 of the movable lamella 1 with respect to the center of the hole 15.
  • the rotation of the fins begins from the bottom of the shutter upwards.
  • the opening of the movable lamella 1 in the projecting window mode occurs by contacting the surfaces 14a on the oblique section 4b of the supports 2 and 2a (fig. 1), and this allows the opening of the movable lamella 1 up to 60° (figs. 1 and 10) .
