Description

Rolling shutter

Object of the invention

This Utility Model refers to a novel roller blind that incorporates important improvements in relation to what is known in art previous.

More precisely, the blind is of the type constituted by slats articulated with each other consecutively by their longitudinal edges, which together have the ends on two vertical side guides of a frame, and where The upper blade is fixedly linked with a winding shaft.

This new blind allows to be positioned with the same typical drive mechanism, for example a tape winding mechanism, in the position of total occlusion of the vain, like the known blinds, allowing a diversity of intermediate positions regulating the passage of light and air; also in  said total occlusion position has a provision of structural reinforcement of the slats.

Background of the invention

They are known roller blinds constituted in some cases by wooden slats and in other embodiments with hollow profiles made of various materials, sheet metal steel, aluminum, plastic material, where such tablets or profiles have at the longitudinal edges elements of hinged joint. These blinds serve to close the opening of the frame but do not enable the entry of light and air with the curtain low, which is an inconvenience for these realizations

Also known are roller blinds in which tablets or profiles are linked by mechanisms of articulation that in the low curtain position also allow the tilting of said slats or profiles to a position substantially horizontal end in relation to the virtual plane of the vain, thus forming a barrier to close the opening and enabling the regulated passage of air and light.

Curtain improvements are also known and shutters that are characterized because at least one means of articulation is provided with a perforation that allows the passage of a support means of a stretch of mesh fabric and whose medium of support is associated with a retention means.

Other references of the prior art are disclosed in patents referring to Venetian blinds vertical, in improvements in the mechanism of control of curtains type American, and in blinds formed by a plurality of slats swivels that hang vertically.

In addition, there are patents that refer to a mechanism improved for simultaneous actuation of forming boards blinds, which protect a folding blind and a blind against storm.

Improvements are also known in blinds to splints blinds with opening regulating device the slats, blinds sheet supports and mechanism clutch for vertically suspended leaf blinds, slatted slats applicable for kiosks and others.

We can add to this background, mechanisms for the operation of mobile slatted slats, tilt transfer mechanisms for a set of Venetian blind; bumper against rainwater for a window; and metal safety curtain applicable to openings such as stained glass windows.

Improvements are also known in blinds of slats adjustable angularly as components of speakers, aerators and other uses; a construction team for assemblies of sliding windows horizontally and vertically; improvements in blinds with fixed and mobile slats of the type in position closing, the splint assembly is locked by a lever layered that keeps tension springs tense while when unlocking, the recovery of the springs causes the upward displacement and total opening of said set. He Subject of this prior patent is characterized in that the framework of the shutter has a removable top cover and on the inner side of the front faces of its sides said frame has guides with which are related to two bearer profiles of the set of fixed slats, behind which is a set of mobile slats mounted on paths side rods of support.

You can also mention improvements in blinds for darkening and / or ventilation of environments, which characterized in that at the ends of the slats are arranged heads equipped with their rotation axes and also one of them is  complemented in its adjacency with an appendix. The axes are inserted in one side and directly in holes of the parantes and on the other side by means of the interposition of a guide with "Y" shaped openings that are provided in amount corresponding to the tablets; they are also Known roller shutters of tilting slats, of the type presenting a traction chain and a chain of positioning of linked links in an articulated way, of so that these links have their joints aligned in a closed state with the links corresponding to the chain of  positioning, characterized because the links of said positioning chain overlap the links in the chain traction. The links thus overlapping force to form in the frame Very wide guides, which is a disadvantage in these prior art accomplishments.

Brief Description of the Invention

As it emerges from the cited documents previously, none of them can be considered an obstacle to granting of the privilege of the requested Utility Model, since that the roller blind that is now proposed, has elements novel that justify it.

Indeed, the invention to be described provides a rolling shutter composed of slats comprising equal profiled elements, each formed by a comparatively flat tubular portion that has a straight longitudinal fin on one of the edges, and on the Opposite edge coincidentally has a groove whose width is somewhat larger than that of said fin. In each blade, the height of the fin is similar to the height of the cavity of the tubular portion; likewise each fin comprises blind wall portions alternated by wall portions
puffs

The groove of each blade and the longitudinal edge free of the fin corresponding to the consecutive slat have cooperating anti-extraction elements in butt game, capable of allow, the pivoting of the fin in the corresponding groove and the free transverse (insertion) displacement of each fin in the cavity of the corresponding tubular part.

Lowering the blind more or less, openwork fins can run between a position where are exposed and therefore the passage of air and light can be regulated, and another position in which said fins are housed in the cavities of the tubular portions of the immediate slats consecutive, providing in this situation a reinforcement structural interior of the slats.

This way you can count on a curtain of roll that combines robustness and versatility and that can be installed easily replacing pre-existing roller blinds without Need for tools or special knowledge.

Other features and advantages of the object of The invention will be explained in the description that follows.

Detailed description of the invention

As it arises especially from figures 1 and 2, the present rolling shutter is constituted by a plurality of slats 10 articulated consecutively by the edges longitudinal and said blind can be adapted to any enclosure frame M of the type typically comprising a pair of G side guides for mounting the ends of the assembly of slats 10, where the mentioned guides G have the ends open superiors to link with an enclosure in which it is mounted a winding roller R associated with a mechanism of drive (not shown).

Each strip 10 comprises a profiled element preferably made of plastic material, it can also be constructed of aluminum or other appropriate material, comprising a tubular part 11 with substantially cross section comparatively flat rectangular, defining two major walls opposite and two minor walls or longitudinal edges, one of the which has a projecting fin 12 straight and parallel with the plane virtual middle of the slat and the opposite edge is provided with a slot 13 coinciding with the projection plane of said fin 12. Slot 13 of each blade is intended for insertion of the fin 12 of another immediately consecutive slat 10.

The groove 13 and the free longitudinal edge of the fin have cooperating anti-extraction elements in butt set, capable of allowing, in consecutive slats, the pivoting of the fin 12 in the corresponding slot 13 and free movement (insertion) of each fin 12 in the cavity of the corresponding tubular part 11.

Flap 12 has the same length as plank 10 and height similar to the cavity of the tubular part 11.

In the preferred embodiment the fin 12 of each blade 10 has the free longitudinal edge 14 folded in the form of "J". Slot 13 has a width somewhat greater than the thickness of fin 12 and an inner flange longitudinal 15 as a stop and pivot support of the edge 14 in "J" form belonging to the 10th consecutive lama immediate.

A feature of the invention is that fin 12 of each blade 10 comprises blind wall portions alternated by openwork portions 16. Perforations or openings 16 forming the draft can have any conformation; also in the assembly of the blind, said perforations 16 of 10 consecutive slats can coincide vertically, as in the illustrated example, or present another location to form in the set of slats 10 a chosen figure.

The constructive solution given to the slats 10 in base to the present invention allows to adapt the blind to any M frame of the type already mentioned and outlined in the Figures 1 and 2. Simply cut the slats 10 in the required length The assembly of the blind is done by adding one lama at a time from the end of the last lama of the blind, sliding the flap 12 along the groove 13 of said latter slat of the blind.

The "J" shaped terminals 14 of each plank 10, when resting on the longitudinal flanges 15 of the grooves 13 of the consecutive upper slats, produce concatenation of the lamas; also said terminals 14 and flanges 15 respectively form joint fulcrums that enable the pivot between consecutive slats and their adaptation to curvature of the roller R.

When lowering the blind and to the position in the that the last lower lama 10 touches the lower watershed of the M frame, fins 12 of the slat assembly are maintained concatenated finding terminals "J" 14 supported by flanges 15. In this way the slats hang consecutively and the respective fins 12 are exposed. In this position of closing the blind, the slats 10 form a visual barrier and the openings allow the passage of air and light, as shown in the Figure 3 and in the upper half of Figure 1.

By continuing to lower the blind, fins 12 they move inside the cavities of the tubular portions 11 of the immediate slats and the curtain is completely closed (figure 4).

As can be seen from figure 1, going down in greater or lesser proportion the blind can regulate the passage of air and light; also, in this way the drawing they form is varied the perforations 16 of the exposed fins granting the Blind a chosen decorative visual effect.

It is also worth mentioning that, in the position of total closure, being the set of fins 12 housed in the tubular portions 11 of the immediate slats, constitute a structural reinforcement of the slats, which gives the greater set mechanical strength.

It is considered that the foregoing description is sufficient for any person skilled in the art to understand the scope of the invention and the advantages derived therefrom. Although the preferred embodiment of the rolling shutter object of this Utility Model has been illustrated, it is recorded that, when implemented, it may have structural modifications in order to adapt it to the needs and / or requirements that must be taken into account for its best operation, without thereby altering or distorting its constructive features and
functional.
