    Field of the invention The invention is in the field of sun protection devices and more particularly relates to a parasol of the folding head type. The invention also relates to a method of folding the head of such an umbrella. State of the art
    Among the existing sun protection devices, parasols are known, that is to say the devices provided with a foot to be fixed to the ground, and carrying a head away from the ground.
    The head is typically made of a plurality of ribs extending radially about a central axis, on which is fixed a fabric capable of filtering at least a portion of the sun's rays when struck by said spokes. The whales are generally hingedly attached, on the one hand, to the foot, and on the other hand, to a sliding ring, fitted on the foot, capable of occupying two extreme positions. According to a first extreme position of the ring, the whales are folded on the foot, as well as the canvas, and in a second extreme position the whales are deployed radially around the foot, exerting efforts on the canvas to stretch and to give it the shape of a spherical cap. When the canvas is stretched, it projects a shaded surface on the ground, thus forming a shelter against the sun's rays.
    These parasols have the particular disadvantage of not being usable when the wind blows at relatively high speeds, typically a few tens of kilometers per hour, because of the important windward of the fabric. Wind catch means the surface on which pressure forces are exerted by the wind. These pressure forces generate moments of strength on the whales. These moments of force can generate mechanical stresses in the umbrella head, and cause damage to said head due to a low resistance of the whales to mechanical stresses. In addition, the pressure forces exerted on the canvas of the parasol can, if the mast is poorly fixed to the ground or if said efforts are sufficiently important, to generate a lift phenomenon displacing the parasol in the direction of the wind, thus posing obvious security issues.
    Presentation of the invention
    According to a first aspect, the present invention aims to provide an umbrella adapted to be used when the wind blows, without presenting problems of danger or deteriorate.
    Another object of the invention is to provide an umbrella adapted to project a shaded surface on the ground, fully usable by a user.
    A further object of the present invention is to provide an umbrella whose use is simple and fast.
    The present invention relates, in a first aspect, to an umbrella comprising a foot comprising a mast, and a head secured to one end of said mast, comprising a fabric capable of filtering at least a portion of the sun's rays and a support structure of said canvas. Said support structure is deformable between a first so-called deployed configuration, in which the fabric is stretched, and a second so-called folded configuration, in which the fabric is folded. The support structure comprises a first arch closed on itself, said peripheral arch, forming part of a plane in the deployed configuration of the supporting structure, and the fabric is fixed inside the peripheral arch of such so that said fabric is stretched within said circumferential arch in the deployed configuration of the support structure.
    When the support structure occupies its deployed configuration, the umbrella is in the position of use, that is to say that the fabric is able to project a shaded surface on the ground.
    In this deployed configuration, the parasol head advantageously has a substantially flat geometric shape, able to be placed substantially parallel to the wind direction. The thus placed head therefore has little or no wind, so the wind pressure forces on said head are absent or relatively low. Thanks to these characteristics of the umbrella head, the umbrella can be used when the wind blows, without presenting any danger problems, nor deteriorating.
    According to particular embodiments, the invention also satisfies the following characteristics, implemented separately or in each of their technically operating combinations.
    In particular embodiments of the invention, the peripheral arch is elastically deformable between a position, called "free position", in which it is deployed so as to tension the fabric, and a position called "constrained position", in which is folded on itself in a substantially flat conformation.
    The free position of the peripheral arch corresponds to the deployed configuration of the support structure, and the constrained position of said peripheral arch corresponds to the folded configuration of the support structure. The peripheral arch is elastically deformable, once deformed, it tends to resume the shape it occupied before deformation and generates efforts to this end. The mechanical stresses to which the circumferential arch is subjected in the constrained position oppose these forces so as to cancel them and maintain said arch in the constrained position. The peripheral arch is adapted to resume its original shape spontaneously when no longer subject to mechanical stresses, and therefore to deploy and stretch the fabric. Therefore, it is easy and fun to put the umbrella in the position of use. In addition, the deployment of the canvas is achieved faster than that of the parasols of the state of the art.
    The umbrella is configured such that, when the peripheral arch occupies its constrained position, said peripheral arch is elastically deformed so as to fold the fabric on itself and to have a substantially flat shape. The umbrella then occupies a storage position in which it is able to be easily transported and stored.
    Advantageously, the head is secured to said end of the mast by a hinge system comprising a first hinge means attached to the head and a second hinge means attached to the mast, said first and second hinge means cooperating with each other.
    These first and second means of articulation are adapted to form an articulation with which the head is adapted to adopt different positions relative to the mast.
    In particular embodiments of the invention, the first hinge means is disposed at the periphery of the head.
    By this feature, when the umbrella is in the use position, the fabric is adapted to project a shaded surface on the ground, fully usable by a user, to the extent that the mast is disposed outside of said shaded surface .
    In particular embodiments of the invention, the support structure comprises a second arch closed on itself, called "inner bow", fixed inside the peripheral arch and to which the fabric is fixed, the first articulation means being fixed to a spacer, fixed inside the inner bow so as to extend between two diametrically opposite points of the inner bow.
    With these features, the umbrella is simple to design and implement. Thus, the cost of the parasol is relatively low, and any maintenance operations are facilitated, such as spare parts.
    In particular embodiments of the invention, the first articulation means and the second articulation means are configured so as to allow the head to be movable relative to the foot in at least one degree of freedom of rotation.
    The hinge means are preferably configured so that the head is rotatable relative to the mast in a mechanical connection of the ball type, in order to change the orientation of the head relative to the mast along three axes of rotation.
    Thus, the head can easily be arranged substantially parallel to the wind direction so that it has little or no wind hold.
    The head can advantageously be secured to the foot removably, so that it can be detached from the foot.
    In particular embodiments of the invention, the support structure comprises a third hoop closed on itself, said "intermediate hoop", arranged between the peripheral and inner hoops, fixed at a point of inner tangency of the hoops peripheral, and attached to the canvas on at least a portion of its periphery.
    Advantageously, the intermediate arch is elastically deformable between a position, called "free position", in which it is deployed, and a position called "constrained position", in which it is folded on itself in a substantially flat conformation. The free position of the intermediate hoop corresponds to the deployed configuration of the support structure, and the constrained position of said intermediate hoop corresponds to the folded configuration of the support structure. The intermediate arch is substantially coplanar with the peripheral arch. The intermediate hoop makes it possible to provide additional resistance against the forces exerted by the weight of the head on the support structure, higher or lower depending on its dimensions, and, if appropriate, by the wind on the structure Support.
    In particular embodiments of the invention, which the mast is of adjustable length.
    Thus, when the umbrella is in its storage position, the length of the mast can be minimal, and the head folded against the mast, so as to reduce the size of the umbrella. The parasol can therefore be transported and stored easily.
    In particular embodiments of the invention, the mast comprises a fixing means in the ground.
    According to a second aspect, the present invention relates to a method of folding the head of an umbrella, comprising: a first step of folding one opposite the other two opposite points of the peripheral arch while applying a twisting force on said peripheral arch so as to rotate a portion of the head substantially 180 degrees with respect to another portion of said head; a second step of folding the two parts of the head; against each other, so as to form an intermediate arrangement in which the circumferential arch forms two rings superimposed on each other, - a third step of repeating the first and second steps on the intermediate arrangement as well as formed, so as to constrain the support structure into its folded configuration, - a fourth step of immobilizing the support structure in said configuration folded by a fastening means.
    Preferably, when the support structure comprises an intermediate hoop and the peripheral hoop is manipulated during the implementation of the method of folding the umbrella head, this manipulation causes deformations of the intermediate hoop substantially similar to those undergone by the peripheral arch.
    The present invention also relates to a method for unfolding the head comprising a step of releasing the support structure in which the user acts on the attachment means in order to render the mobility to the support structure so that it finds spontaneously its deployed configuration.
    Presentation of the Figures The invention will be better understood on reading the following description, given by way of non-limiting example, and with reference to the figures which represent: FIG. 1: a perspective view of an umbrella according to FIG. invention, a support structure is in an expanded configuration, - figure 2: a perspective view of the umbrella according to Figure 1, the support structure is in a folded configuration, - figure 3: a perspective view of the umbrella according to FIG. 1 in the storage position, FIG. 4: a perspective view of a spacer hingedly attached to the base of the parasol according to FIG. 1, and a detailed view of a hinge system of the head of parasol at the base of the umbrella fixed to said spacer, - Figures 5 to 8: successive steps of folding of the umbrella head according to Figure 1.
    Detailed description of the invention
    The present invention relates to a parasol 10, as represented by FIGS. 1 to 3 in a non-limiting exemplary embodiment, comprising a parasol head 10, referred to as "head" in the rest of the text, integral with a foot 30 of parasol 10, called "foot" in the rest of the text. More specifically, the foot 30 comprises a mast 32 extending between two opposite ends, the head 20 being integral with one of these ends.
    The head 20 is formed by a support structure 21 comprising at least a first peripheral arch 210 closed on itself, elastically deformable. By "peripheral arch closed on itself" means that the peripheral arch 210 has a geometric shape whose contour is closed, as shown in Figure 1, so as to define an inner area. The peripheral arch 210 is able to be deformed elastically, from a position called "free position", to a position called "constrained position", when it is subjected to efforts of sufficient intensity, that is to say say higher than a given value. When the forces are no longer applied to said peripheral arch 210, or when their intensity is insufficient, that is to say less than a given value, the peripheral arch 210 is advantageously able to spontaneously resume its free position. The free position is the position occupied by the peripheral arch 210 before deformation, that is to say, a position in which it is deployed. When it occupies its deployed position, the peripheral arch is inscribed in a plane.
    A fabric 22 adapted to filter at least a portion of the sun's rays is fixed inside the peripheral arch 210.
    In a first configuration of the support structure 21, called "extended configuration", as shown in FIG. 1, the peripheral arch 210 occupies its free position, and the fabric 22 is stretched. When the fabric 22 is stretched by the peripheral arch 210, said peripheral arch 210 preferably exerts tensioning forces over the entire periphery of the fabric 22. By way of example, the peripheral arch 210 is engaged in a or dwellings developing along the periphery of the canvas 22.
    Alternatively, the peripheral arch 210 may be fixed to the fabric 22 by any fixing means known to those skilled in the art, permanent or removable.
    The fabric 22 comprises a face 221 called "upper face", which is intended to receive the sun's rays when the umbrella 10 is in the position of use, and a face 222 called "lower face", which is intended to remain facing of the soil when the umbrella 10 is in use position.
    The support structure 21 also comprises a second arch, called "inner bow" 211, closed on itself so as to define an inner area, and fixed to the fabric 22, for example, against a face 221 or 222 of the fabric 22. As shown in FIG. 1, when the support structure 21 occupies its deployed configuration, the inner arch 211 is disposed inside the peripheral arch 210, contiguous at a point of internal tangency 23, and is substantially coplanar with the latter. The inner bow 211 is preferably circular in shape. The inner bow 211 may be made of any elastically deformable material.
    The support structure 21 may comprise a third hoop called "intermediate hoop" 212 disposed between the peripheral and inner hoops 210 2101. In a similar manner to the peripheral 210 and inner hoops 211, the intermediate hoop 212 is closed on itself, of so as to form an inner surface, and fixed to the fabric 22, for example, against one of its faces 221 or 222. The intermediate arch allows to provide additional resistance against the forces exerted by the weight of the head on the supporting structure, higher or lower depending on its dimensions, and, if necessary, by the wind on the support structure.
    Advantageously, similarly to the peripheral arch 210, the intermediate arch 212 is elastically deformable between a position, called "free position", in which it is deployed so as to stretch a portion of the fabric, and a position called " constrained position ", in which it is folded on itself in a substantially flat conformation. The intermediate hoop 212 may be made of any elastically deformable material. By way of nonlimiting example, the surface of the inner area delimited by the intermediate hoop 212 is twice as large as the surface of the inner area delimited by the internal hoop 211.
    Preferably, the hoops 210, 211 and 212 are arranged relative to each other contiguously at a point of inner tangency 23. The point of tangency 23 is called "point of inner tangency" insofar as the intermediate hoops 212 and 211 are respectively disposed inside the peripheral arch 210. The peripheral arch 210 is the arch most subjected to mechanical stresses, such as the forces generated by the weight of the head and / or the forces generated by the wind. It is therefore dimensioned to have a higher mechanical strength to intermediate hoop 212 and inner 211. The cross section of the peripheral hoop 210 thus has larger dimensions than the cross section of the intermediate hoop 212. In the same way, intermediate hoop 212 may be sized to have a greater mechanical strength than the inner hoop 211, its cross section may therefore have dimensions greater than the dimensions of the cross section of the inner bow 211.
    In the nonlimiting exemplary embodiment illustrated by FIGS. 1 and 5, the peripheral and intermediate hoops 210 and 212 are substantially of ovoid geometrical shape. More specifically, said peripheral and intermediate hoops 210 and 210 respectively develop in two transverse portions joined together by two longitudinal portions symmetrical with respect to an axis of symmetry S. The two transverse portions each have the geometric shape of an arc of a circle, the radii of said arcs being of different values from each other.
    Preferably, the peripheral arches 210 and intermediate 212 are fixed to each other, at the point of inner tangency 23, by one of their transverse portions. More particularly, as illustrated in FIG. 1, said peripheral and intermediate hoops 210 are fixed at the point of internal tangency 23 by their respective transverse portion, the radius value of which is the smallest.
    The head 20 is secured to the mast 32 by a hinge system 24. Advantageously, the articulation system 24 can be fixed at the periphery of the peripheral arch 210.
    The articulation system 24 comprises a first articulation means 243 fixed on the head 20 and a second articulation means 31 fixed on the mast 32.
    The first hinge means 243 is attached to a spacer 240 fixed inside the inner bow 211 so as to connect two points of the inner bow 211 diametrically opposed. The spacer 240 extends along a longitudinal axis, and comprises two opposite ends each respectively comprising an end face. Each end face advantageously comprises a notch 241, 242 intended to receive a portion of the inner bow 211.
    In the exemplary embodiment illustrated in FIGS. 1 and 5, the spacer 240 is adjacent to the point of internal tangency 23 of the inner hoops 211, intermediate 212 and peripheral 210, by one of its ends called "proximal end", its other end. end, said "distal end" being distant from said point of inner tangency 23, so that the mast 32 is eccentric with respect to the head 20.
    Alternatively, the spacer 240 may not be adjacent to the point of inner tangency 23.
    In the exemplary embodiment illustrated by the detail view of FIG. 4, the notch 242 made on the face of the proximal end of the spacer 240 comprises several impressions so as to receive successively, juxtaposed with each other, the internal arch 211, the intermediate arch 212 and the peripheral arch 210. The impressions are dimensioned to correspond to the dimensions of the straight sections of the peripheral, intermediate and intermediate hoops 210 210 and 212. The notch 241 made on the face the distal end preferably comprises only one footprint in that it is intended to receive only the inner bow 211.
    Alternatively, in other embodiments not shown in the figures, the notches 241, 242, end faces may comprise only one footprint each.
    Advantageously, the spacer 240 and the inner bow 211 are mechanically linked by a tight type adjustment, made, for example, by a slight deformation of the inner bow 211, generating a holding tension of the spacer 240. Alternatively , the spacer 240 may be mechanically linked to the inner bow 211 by any other fastening means known per se.
    Preferably, the second articulation means 31 is located at one end of the mast 32, called "upper end".
    As represented by FIG. 4 by way of nonlimiting example, the first articulation means 243 may comprise a sphere 244.
    Preferably, the sphere 244 is kept at a distance from the spacer 240 by means of a shaft 245 whose longitudinal axis extends, for example, perpendicularly to the longitudinal axis of the spacer 240, as represented by FIG. detail view of Figure 4.
    Preferably, the shaft 245 is arranged in the vicinity of the proximal end of the spacer 240. The spacer 240, the shaft 245 and the sphere 244 can be obtained in one piece, by molding.
    However, alternatively, the shaft 245 may be attached to the spacer 240 by a screw / nut type assembly or by any known assembly means, and the sphere 244 may be permanently attached to the shaft 245, for example example, by gluing.
    The second articulation means 31 is intended to cooperate with the first articulation means 243, so that the head 20 is able to be movable relative to the foot 30 according to at least one degree of freedom in rotation.
    In other embodiments not shown in the figures, the first and second articulation means 243, 31 may form between them a pivot type mechanical connection or a mechanical connection having two degrees of freedom in rotation.
    Preferably, the hinge system 24 allows the articulation of the head 20 relative to the foot 30 according to a mechanical connection of the ball joint type.
    Preferably, the second articulation means 31 comprises a housing of complementary shape to the sphere 244, so that said sphere 244 is able to pivot in the housing according to at least one axis of rotation.
    The second articulation means 31 also comprises means for locking in rotation of said sphere 244. For example, the housing is provided with a clamping member adapted to deform said housing, within the limits of its elastic limit, so as to apply a clamping force on the sphere 244 sufficient to lock said sphere 244 in rotation.
    In a non-limiting embodiment, the head is secured to the foot removably, so that it can be detached from the mast. Thus, a user can in particular use heads of different dimensions with a single foot.
    As shown in Figures 1 and 4, the mast 32 is provided at its other end, called "lower end", a fixing means 33 in the ground.
    Advantageously, the fixing means 33 in the ground consists of a thread on a portion of the length of the mast 32, whose cross section decreases towards the lower end of the mast 32. Thus, the parasol 10 can be screwed into the ground furniture or in any suitable housing so as to make a screw / nut assembly.
    Alternatively, the fastening means 33 may be formed by any arrangement or device known to those skilled in the art, such as the conformation of the lower tip-shaped end.
    Advantageously, the length of the mast 32 can be adjustable between two minimum and maximum extreme lengths, respectively represented by FIGS. 1 and 4. For this purpose, the mast 32 can be telescopic, so that it can be divided into minus two coaxial portions nested one inside the other and slidable relative to each other.
    The mast 32 then comprises stop means in translation of the portions between them. For example, one of the portions is provided with a clamping member adapted to deform said portion so as to apply a clamping force on the other portion sufficient to block the portions in translation.
    In the non-limiting embodiment shown in Figures 1 to 4, the mast 32 is divided into four portions, three of which are provided with clamping members.
    Alternatively, in other embodiments not shown in the figures, the portions of the mast 32 may be hingedly attached to each other, so as to occupy respectively a folded position in which they are adjacent to each other, over their entire length, and an unfolded position in which they are coaxial and adjacent to each other by each of their ends.
    The umbrella 10 may advantageously occupy a position of use, in which the support structure 21 occupies its deployed configuration, as shown in FIG. 1, the fabric 22 being deployed.
    In this position, the fabric 22 is deployed and is intended to project a shaded surface on the ground, when struck by sun rays, to provide shelter for a user against said rays.
    Figure 3 shows the umbrella 10 in the storage position, the support structure 21 occupying a second configuration, called "folded configuration" and the mast 32 is adjusted so that its length is minimal. In this folded configuration of the support structure 21, the peripheral arch 210 and the intermediate arch 212 are elastically deformed, in the stressed position, so as to fold the fabric 22 on itself, as described more specifically in the following. text.
    In this position, the umbrella 10 is intended to be transported or stored.
    In order to change the position of the umbrella 10, from a use position to a storage position, the user must perform steps to conform the support structure 21 in folded configuration. Figures 5 to 8 respectively show an embodiment of the successive steps of a method of folding the head 20 according to the invention.
    FIG. 5 shows a first step consisting in folding one point of each longitudinal portion of the peripheral arch 210 against each other. The points are preferably chosen so that their orthogonal projection with respect to the axis of symmetry S passes through the inner area defined by the intermediate hoop 212, and is preferably substantially symmetrical with respect to each other along the axis of symmetry S.
    At the same time, a twisting force is applied on the peripheral arch 210 so that respective portions of the upper faces 221 and lower 222 of the fabric 22 are simultaneously apparent in the same plane. Part of the head 20 is thus rotated, substantially over one hundred and eighty degrees with respect to another portion of said head (20). These two parts respectively correspond to each of the upper faces 221 and lower 222 of the web 22. The head then takes substantially the form of a lemniscate.
    It should be noted that the manipulation of the peripheral arch by the user, during the implementation of the folding process, causes deformations of the intermediate arch substantially similar to those undergone by the peripheral arch.
    In a second step, the two parts of the head 20 are then folded against each other, so that the portions of the upper faces 221 and lower 222 are disposed opposite one another as shown in FIG. 6. An intermediate arrangement is thus formed, in which the peripheral arch 210, as it is deformed following these steps, forms two rings superimposed on each other, as well as the intermediate hoop 212.
    Preferably, but not exclusively, the hoops 210, 211 and 212 are manipulated so that the intermediate hoop 212 is substantially concentric with the inner hoop 211 and that their diameter is substantially identical.
    A third step consists in repeating the first and second steps carried out above, the two points to be folded against each other being two diametrically opposite points of the peripheral arch 210, as illustrated by FIG. head 20 then has a disk shape whose diameter is substantially equal to the diameter of the inner bow 211, formed by a superposition of portions of arches.
    It should be noted that when the peripheral and intermediate hoops 210 and 212 are in the stress position, they exert tension forces in that said peripheral 210 and intermediate hoops 212 seek to resume their free position, that is to say say their initial form, deployed.
    Fig. 8 shows a fourth step of immobilizing the support structure 21 in its folded configuration resulting from the previous folding steps. Indeed, it is necessary to immobilize the peripheral arches 210 and intermediate 212 to maintain this shape. This step of immobilizing the support structure 21 is performed by an attachment means 25 opposing the tensioning forces exerted by the peripheral arches 210 and intermediate 212 to bring them back to the free position.
    As represented by FIG. 8 in a nonlimiting exemplary embodiment, the attachment means 25 comprises a strap fastened at the periphery of the head 20, intended to be disposed on either side of the head 20 so that it surrounds diametrically said head 20. The strap can be fixed at one of its ends to the point of inner tangency 23 of the hoops 210, 211 and 212, and may comprise a means for removably fixing the strap on itself in one attachment point.
    Preferably, the head 20 has reference means for a user to determine the position of the points of the peripheral arch 210 to fold against each other during at least one of the steps described above.
    These reference means may be colored marks fixed, for example, on the housing or housing developing along the periphery of the fabric 22.
    It should be noted that the material constituting the peripheral hoops 210 and intermediate 212, as well as their dimensions, are determined so that said hoops do not deform beyond their elastic limit during the stages of folding of the head 20. In this context, the deformation of these peripheral 210 and intermediate hoops 212 is always reversible.
    To change the position of the umbrella 10, from a storage position to a position of use, the unfolding of the head 20 is performed without any other intervention of the user than that of releasing said support structure 21 of the means of attachment 25.
    Indeed, the tensile forces exerted by the peripheral and intermediate hoops 210 210 tend to spontaneously bring back the support structure in deployed configuration.
    In other exemplary embodiments of the invention, the material constituting the peripheral arch 210, as well as the dimensions of its cross-section and of the interior area that it defines, are such that it has sufficiently high rigidity to maintain the head 20 in a substantially flat shape when the support structure 21 is deployed, without intermediate hoop 212. It is within the skill of the art, on the basis of his general knowledge, to make such a choice of material and dimensions of the peripheral arch 210 adequate.
    More generally, the scope of the present invention is not limited to the embodiment described above by way of non-limiting example, but extends on the contrary to all modifications within the scope of the man of the invention. 'art.
