    DESCRIPTION STABLE ROLLER
    The present invention relates to a roller blind, or windbreak curtain, comprising a canvas arranged vertically and which is attached by its lateral edges to guides. In particular, the roller blind of the present invention ensures proper operation when wind blows occur and, at the same time, is less sensitive to manufacturing and assembly tolerances.
    Background of the invention
    Roller blinds comprising a canvas, a winding shaft for collecting the canvas coupled to a first edge thereof, a loading bar coupled to a second edge of the canvas, opposite the first edge, are known in the state of the art. and two guides that extend longitudinally along the direction of the canvas movement (generally the vertical direction, although in some cases it can also be the horizontal direction or a direction with a certain inclination with respect to the horizontal direction), each defining in its interior a cavity and being provided with a slit through which the canvas is inserted.
    These blinds have the disadvantage that, when wind blows occur, areas of the canvas that were inserted in the guides can leave them, giving rise to a bag effect that degrades the esthetics of the blind and the fabric of the canvas. In addition, when holes are created between the guide and the edge of the canvas in those areas where the canvas that has left the guide, the blind stops performing its function of integral sun protection, blocking the light, as well as protection against wind.
    An attempt to solve this problem is to place retention elements on the lateral edges (or perpendicular to the winding axis) of the canvas that are housed in the cavity of the blind guides, forming a structure similar to half a zipper. These retention elements have a thickness greater than the width of the slit of the guides in order to prevent the canvas from leaving the guides. Publications ES106579U, AU2009212839 and CN201095948U show some examples of roller blinds with retaining elements (also called blinds with zip or zip system).

    However, this solution has several drawbacks. First, the glutton slit has to be very narrow to prevent the retention elements from leaving, thus increasing! the friction of the canvas with the slit. This, on the one hand, accelerates the wear of the canvas and, on the other, forces to use heavier load bars to overcome the resistance to movement caused by friction.
    In addition, the system is very sensitive to the tolerances in the installation of the blind. For example, a slight inclination of the glues with respect to the vertical can mean that the retaining elements, or even the loading bar itself, are locked against the glutton slit.
    Roller blinds are also known in the state of the art in which the retaining element consists of a hem on each of the lateral edges of the canvas, which is obtained from the superposition of several layers of the material that forms the canvas, and that can be housed inside the cavity of each of the glues. Publication WO2014 / 009573 discloses such a roller blind.
    This solution, compared to the previous one, is simpler to manufacture since it is not necessary to hold a plurality of retaining elements along the lateral edges of the canvas, either by sewing or welding. However, the solution based on a hem does not solve the problems described.
    It would therefore be desirable to have a roller blind with a wind blow protection system that exhibits less friction of the retaining elements with the groove and is less sensitive to manufacturing and assembly tolerances.
    Description of the invention
    With the roller blind according to revindication 1, the aforementioned problems can be resolved, presenting other advantages that will be described.
    One aspect of the present invention relates to a roller blind, comprising: a
    canvas; a winding shaft to collect the canvas, said shaft being coupled to a first
    edge of the canvas; a loading bar coupled to a second edge of the canvas, the
    second edge opposite the first edge; and two glues that extend longitudinally to the
    along the direction of the canvas movement, each defining inside

    cavity and being provided with a slit through which the canvas is inserted into said cavity; wherein the canvas comprises in each of its lateral edges, perpendicular to the winding axis, a hem (sometimes also referred to as a bag), said hem being able to remain inside the cavity of each of the glues. Said roller blind is characterized by the fact that the hem on each of the side edges of the canvas forms a tube (also referred to as a conduit, or closed cross-sectional channel) which comprises inside a retention strip arranged at length of said tube; wherein the cross-sectional area of said tube is larger than the cross-sectional area of the retention strip; and where the thickness of said hem with the retention strip housed inside its tube is greater than the width of the slit of the glutton in which it is inserted, preventing the hem from leaving the glutton completely.
    As the cross-sectional area of the hem tube is larger than the sectional area of the retention strip, the retention strip is loosely disposed within the hem tube. In this way, the retention strip is pressed against the slit of the gluttony only when there is a wind blow that tends to drag the hem of the canvas towards the outside of the cavity. Consequently, the roller blind of the present invention reduces friction between the canvas and the slit.
    This clearance also allows to absorb errors in the sliding of the canvas, due for example to the tolerances in the assembly of the glues. Therefore, as the retention strip can move inside the hem tube, the risk of it being locked with the slit of the glutton is reduced.
    In addition, the roller blind of the present invention is less sensitive to the tolerances of fabrication of the canvas, unlike what with the blinds of the state of the art with retaining elements fixed to both frames of the canvas, where the precision In the alignment of the retaining elements that make up the half zip is usually critical.
    The clearance provided by the hem tube also facilitates the insertion of the retention strip during assembly. In addition, when the canvas of the blind is wound, the slack of the tube allows the retention strip to be positioned differently for each turn of the canvas around the winding axis, thereby achieving a more compact winding.

    In the context of the present invention, the thickness preferably refers to the dimension according to a direction perpendicular to the direction according to which the slit of the glutton extends.
    Advantageously, since the hem of the canvas thickened with the retention strip inside the hem tube, it is not necessary that the slit of the glues be very narrow, unlike what happens with the blinds in which the hem of the canvas is constituted merely by the superposition of several layers of material. Therefore, it is possible to use grooves with a wider range of widths and more conventional values than those used in the state of the art solutions.
    In some cases, the retention strip comprises a first end coupled to the first edge of the canvas and / or to the winding axis, and a second end coupled to the second edge of the canvas and / or the loading bar.
    In this way it is not necessary for the retention strip to be held, either by sewing or welding it, at intermediate points of the tube, which simplifies the fabrication of the blind. In addition, in the case where the retention strip is coupled to the winding axis and the load bar, the retention strip also acts as a glider for movement of the canvas.
    The cross-sectional area of the hem tube is preferably at least twice the cross-sectional area of the retaining strip housed therein. However, in some cases the cross-sectional area of the hem tube is advantageously at least three, four or even five times larger than the cross-sectional area of the retention strip housed therein.
    In some embodiments, the retaining strip comprises: a longitudinal connecting member disposed along the hem tube, and a plurality of retaining elements attached to said longitudinal connecting member; wherein the thickness of the longitudinal connecting member is less than the thickness of the retaining elements.
    Preferably, in these embodiments, the thickness of said retaining elements is greater than the width of the glutton slit in which the hem is inserted. This ensures the retention effect regardless of the thickness of the canvas material used.

    In the context of the present invention, the thickness of a retention element, which may be generally irregular, preferably refers to the maximum dimension of said element according to a direction perpendicular to the direction according to which the slit of the glutton extends.
    Also preferably, said retention elements have a spherical or cylindrical shape. The use of rounded shapes is especially advantageous because they reduce the risk of the retaining elements being hooked with the hem. However, in other cases, the retention elements may have other forms.
    Advantageously, in one embodiment said retention elements are integrally formed of a synthetic or plastic material. Alternatively, the retention elements may be metallic. In one case as in the other, preferably the retention elements are molded, by casting or injection, on the longitudinal connecting member. In this way, the retention elements are attached to the longitudinal connection member without the need for additional fastening means.
    In certain embodiments, the longitudinal connection member is integrally formed of a flexible material. The flexibility of the material of the longitudinal connecting member (in particular, in the longitudinal direction) facilitates the winding operation of the canvas and also allows it to be wound in a compact manner.
    Optionally, the longitudinal connecting member and the plurality of retention elements are formed of the same material. This facilitates the manufacturing process of the retention strip, which can be obtained integrally by molding a synthetic or plastic material.
    In other embodiments, the longitudinal connecting member is a string or chain. This solution is particularly economical because of the simplicity of the materials used.
    Preferably, the retaining elements are regularly spaced along the longitudinal connecting member. In this way the retention capacity of the canvas remains uniform for the entire length of it. In addition, the spacing between the retaining elements allows the winding of a turn of the canvas hem over
    another without the retention elements overlapping, allowing the diameter of the

    canvas winding, when fully collected, be smaller.
    In certain embodiments, all retention elements have the same thickness; and preferably the spacing between the retaining elements is less than triple that thickness. In some of these embodiments, the spacing may be less than twice, or even once, said thickness.
    If the separation between the retention elements is very large, a wind blow could drag the hem of the intermediate zone between two consecutive retention elements out of the glutton. The selected spacing ranges prevent this from happening, thereby providing good retention strip behavior.
    Also preferably the two retaining strips of the roller blind, each housed inside the hem tube of each of the two side edges of the canvas, are the same. This is advantageous to ensure that the behavior of the blind in the face of wind blows is the same on both side edges.
    Advantageously, in some cases each of said glues is formed by two glutton profiles that can be coupled together, which, once coupled, determine said cavity and said slit. The use of attachable glutton profiles facilitates the installation and assembly of the roller blind.
    Preferably in these cases, each of said glues includes a protective profile comprising a first portion disposed inside the cavity determined by the two glutton profiles; and wherein said first portion comprises a gap adapted to accommodate the hem of the canvas inside and a groove aligned with the slit determined by the two glutton profiles
    Said protective profile, preferably of plastic, prevents the hem of the canvas from rubbing against the inside of the glutton profiles that determine said cavity.
    More preferably the protective profile comprises two outer portions, each connected to one of the ends of the groove of the first portion, which protrude from the cavity through the slit determined by the two glutton profiles.

    The outer portions prevent the hem of the canvas from rubbing directly on the slit of the guide, being able to degrade. Furthermore, said portions contribute to reducing the width of the slit, favoring that the hem of the canvas (with the retention strip housed inside its tube) can completely exit the guide.

    Description of a preferred embodiment
    Referring to Figure 1, there is shown an embodiment of the roller blind according to the present invention. In particular, the roller blind 1 comprises: a canvas 2; a winding shaft 3 coupled to a first edge of the canvas 2 and which allows it to be collected; a loading bar 4 coupled to a second edge of the canvas 2 opposite the first edge; and two guides 5 that extend longitudinally along the direction of movement of the canvas 2, in this example the vertical direction. Each guide 5 defines inside a cavity 6
    and is provided with a slit 7 through which the canvas 2 is inserted. The canvas 2 comprises

    at each of its lateral edges, perpendicular to the winding axis 3, a hem 8 that can be housed inside the cavity 6 of each of the guides 5.
    Figures 2-4 show a section of the roller blind according to a plane perpendicular to the direction of movement of the canvas, in which the arrangement of the canvas hem, with its retention strip, can be seen in more detail inside the cavity of the roller blind guide according to the present invention. Although the figures only show one of the two guides of the roller blind 1, the structure of the other guide is identical. Figure 2 is a perspective view, while Figures 3 and 4 provide additional plan and front views, respectively.
    The hem 8 on each of the side edges of the canvas 2 forms a tube 20 comprising in its interior a retention strip 21 disposed along said tube 20. The retention strip 21 comprises a first end coupled to the first edge of the canvas 2 and a second end coupled to the second edge of the canvas 2, without it being necessary to hold it at intermediate points of the tube 20.
    The cross-sectional area of the tube 20 of the hem 8 is greater than the cross-sectional area of the retaining strip 21. More specifically, as can be seen in Figure 3, the cross-section of said tube 20 is at least twice the area of the cross section of the retaining strip 21 housed therein.
    The thickness of the hem 8 with the retaining strip 21 housed inside its tube 20 is greater than the width of the slit 7 of the guide 5 in which it is inserted, thereby preventing the hem 8 from leaving completely guide 5.
    A fragment of the retaining strip 21 is shown in Figure 5, which comprises a longitudinal connecting member 50 disposed along the tube 20 of the hem 8, and a plurality of retaining elements 51 attached to said longitudinal connecting member 50 In the figure it can be verified that the thickness of the longitudinal connecting member 50 is smaller than the thickness of the retaining elements 51. Although in this example all the retaining elements 51 are equal, in other examples they may have shapes and / or different thicknesses.
    In particular, the retention elements 51 have a spherical shape and a greater thickness W
    that the width of the slit 7 of the guide 5 in which the hem 8 is inserted.

    In the embodiment of the figures, the longitudinal connecting member 50 is a string and the retaining elements 51 are integrally formed of a synthetic or plastic material molded on said string.
    As can be seen in Figure 5, the retention elements 51 are regularly spaced along the longitudinal connection member 50. More specifically, the spacing S between the retention elements is less than three times its thickness W.
    As shown in Figure 6, each of the glues 5 of the roller blind 1 is formed by two glulable profiles 22a, 22b that can be coupled to each other which, once coupled, determine the cavity 6 and the slit 7 of the glutton 5.
    Additionally, each of said glues 5 includes a protective profile 23 comprising a first portion 24 disposed inside the cavity 6 determined by the two glutton profiles 22a, 22b. Said first portion 24 comprises a recess 25 adapted to accommodate the hem 8 of the canvas 2 inside and a groove 26 aligned with the slit 7 determined by the two gliding profiles 22a, 22b.
    The protective profile 23 also comprises two outer portions 27a, 27b, each connected to one of the ends of the groove 26 of the first portion 24, protruding from the cavity 6 through the slit 7 determined by the two gliding profiles 22a , 22b.
    Although reference has been made to a specific embodiment of the invention, it is evident to one skilled in the art that the described roller blind is susceptible to numerous variations and modifications, and that all the mentioned details can be replaced by other technically equivalent ones. , without departing from the scope of protection defined by the appended claims.
