Definitions

  • the present invention relates to a roller-up shutter with oscillating slats.
  • the patent application W02017009876 describes a roller, shown in figure 1, comprising a plurality of slats that perform a sliding screen in a pair of slide guides, the slats comprising a fixed frame and at least one movable oscillating slat having locking teeth, in which the fixed frame comprises two or more supports, a fixed lower profile, a series of caps, a gasket, so that the weight of the lower fixed profile of the upper slat, acting as a lever, rotates the mobile slat which belongs to the subsequent lower slat, without the use of any guiding mechanism, in which the mobile slat, in the orthogonal position with respect to the horizontal plane, in its upper portion is equipped with a first hook which is introduced into a second hook of the fixed lower profile; the movable slat being provided with a recess, outside the walls of the slat itself, suitable for receiving the element of the supports; the movable slat being configured to perform a rotation
  • roller shutter just described suffers of the problem that its slats flex when the dimensions of the roller shutter exceed 1.8 m in width, due to the weight force .
  • roller shutters with oscillating slats present the problem of a large diameter of the region dedicated to the roller shutter winding and the winding itself.
  • a further problem of the known roller shutters with oscillating slats is to involve complex production processes due to the shape of the known slats.
  • Scope of the present invention is to provide a roller- up shutter with oscillating slats in which the slats do not flex due to the weight force even when the size of the shutter exceeds 1.8 m in width.
  • a further object of the present invention is to provide a roller-up shutter with oscillating slats that allows a winding diameter reduced and that it is easy to produce, thus having characteristics such as to exceed the limits which still affect the current roller-up shutter with oscillating slats with reference to the prior art.
  • a roller-up shutter with oscillating slats is provided, as defined in claim 1.
  • FIG. 1 shows an exploded view of a slat, according to the prior art
  • figure 2 shows an overall view of a roller-up shutter with oscillating slats, according to the invention
  • FIG. 3 shows an exploded view of a slat of the roller-up shutter with oscillating slats, according to the invention
  • figure 4 shows an assembled view of the main elements of a slat of the roller-up shutter with oscillating slats: oscillating removable slat, fixed lower profile and single-walled support, according to the invention
  • FIG. 5 shows a second exploded view of the main elements of the slat of the roller-up shutter with oscillating slats: removable swinging slat, fixed lower profile and single-walled support, according to the invention
  • FIG. 6 shows a side section of a first movable slat coupled to a second movable slat during the opening, and a side section of the fixed lower profile, according to the invention
  • FIG. 7 a and 7.b shows a side view and a perspective view of a second embodiment of a removable oscillating slat of a roller-up shutter with oscillating slats, according to the invention.
  • the roller-up shutter with oscillating slats 200 comprises mobile oscillating slats 300, each consisting of a fixed frame 400, and of at least a removable oscillating slat
  • the fixed frame 400 consists of two or more supports 160 and a fixed lower profile 500.
  • the oscillating removable slat 100 shown in Figure 4, is provided, in the upper part, of a second hook 140 and of a recess 150, for example a trench, which is external compared to the second hook 140.
  • the removable oscillating slat 100 is provided in a lower part of locking teeth 141 which define a seat for a gasket 170 shown in Figure 6.
  • the removable oscillating slat 100 includes a pair of locking teeth 141 specular each other.
  • the removable oscillating slat 100 is inferiorly coupled by means of a first hook 520 of the fixed lower profile 500, thus allowing a 180° rotation of the removable oscillating slat 100 in a winding having a reduced diameter.
  • Such coupling is realized by means of a support 160 of the removable oscillating slat 100.
  • the recess 150 of the removable oscillating slat 100 receives an upper folded head 161 of the support 160.
  • the removable oscillating slat 100 has a fulcrum element 151 shaped as a wedge, next to the recess 150.
  • This fulcrum element 151 has a beveled vertex with a very small radius.
  • the technical purpose of this fulcrum element 151 is to reduce, during lifting, the friction due to rotation.
  • the technical effect of the fulcrum element 151 is greater in the lower part of the roller-up shutter, where the weight underneath the removable oscillating slat is reduced to a minimum.
  • the recess 150 and the upper folded head 161 have curvilinear surface and couple each other so that obtain an advantageous position of the center of rotation.
  • the support 160 is a linear rigid body provided with shaped walls so as to follow the internal profile of the removable oscillating slat 100.
  • the lower portion of the support 160 is provided of a first recess 162a engaged by the first upper protrusion 501a and a second recess 162b engaged by the second lower protrusion 501b of the fixed profile 500 to prevent the lateral support displacement 160 along the recess 501, showed in figure 5.
  • the support 160 can be obtained by cutting a profile of extruded aluminum, by casting of light alloys or forging.
  • the particular conformation of the recess 150, of the removable oscillating slat or mobile slat, and of the support 160 facilitates the construction process of the profile extrusion matrix.
  • the second hook 140 of a removable oscillating slat 100 mate to the fixed lower profile 500, receives the weight of an upper slat of the shutter.
  • the application of this weight force is offset with respect to the fulcrum formed by the recess 150 and the upper folded head 161; as a result of said contrivance a lever is formed causing the rotation of the removable oscillating slat 100 belonging to the next lower slat, without the use of mechanisms (gears, chains or the same) .
  • an external portion of the roller shutter slats comprises at least a cap element 150a having a central support 201 placed, in use, adherent inside a cavity of the oscillating slat 100.
  • the central support 201 has a herringbone conformation, having a central linear element to which a plurality of protrusion is laterally connected.
  • the cap element 150a also comprises at least a vent channel 202, 202a able to evacuate hot air in use, neutralizing the thrust force that would cause the cap element to come out of its seat, at one end of the roller shutter slats.
  • the cap element 150a also comprises a protection element 203 able to protect the internal surface of the oscillating slat 100 during the winding phase, and to protect from atmospheric agents (smog, sea air, etc.) which could compromise the surface treatment of an extruded profile.
  • a protection element 203 able to protect the internal surface of the oscillating slat 100 during the winding phase, and to protect from atmospheric agents (smog, sea air, etc.) which could compromise the surface treatment of an extruded profile.
  • the roller-up shutter with oscillating slats 200 allows to avoid the bending of the roller shutter slats when this has a size major than 1.8 m.
  • roller-up shutter with oscillating slats according to the invention enables a winding of a shutter having light-height of 2.5 m in 19 cm of diameter, thanks to the small size of its slats and its supports.
  • Another advantage of the roller-up shutter with oscillating slats according to the invention is that, thanks to the design of the coupling region of the substrate, the first hook 520 of the lower fixed profile 500 avoids accumulations and consequent release of water, during the rolling phase, inside the house where the shutter is installed.
  • the particular design of the oscillating removable slat, and of the support allows the rolling-up shutter with oscillating slats to reduce the opening angle with a better application of the weight force of the upper slats on the lower ones, a significant reduction in the width of the sliding guides which represents a strength in the installation phase where it is not possible to replace the existing ones.
  • the appropriate rails may be housed within the preceding compartments.
  • the roller-up shutter with oscillating slats allows easy construction of the profiles that make up the slats while being of reduced dimensions.
  • roller-up shutter with oscillating slats here described and illustrated can be subject to modifications and variations without thereby coming out of the protecting scope of the present invention, as defined in the appended claims.
