  • the invention relates to a parasol.
  • a parasol comprising a base, a set of branches extending from the base, and an opaque canvas attached to said branches.
  • the branches are generally articulated relative to the base so as to make the parasol mobile between an extended configuration and a retracted configuration.

  • the parasol is as compact as possible, so as to be able to be stored and/or so as to offer little wind resistance.
  • Such a parasol has the disadvantage of trapping a bubble of heat under the canvas because the canvas prevents air from circulating freely and in particular from escaping upwards.

  • the aim of the invention is to provide a parasol which overcomes the above drawbacks and improves the parasols known from the prior art.
  • a first object of the invention is a parasol capable of producing a large shaded surface, which promotes air circulation at the shaded surface, and which can pass into a particularly compact retracted configuration.
  • the umbrella may be movable between an extended configuration and a retracted configuration, each leaf of said leaf assembly pivoting about its axis of rotation as the umbrella moves from its extended configuration to its retracted configuration.
  • Each leaf of said set of leaves may extend substantially parallel to a plane, and the axis of rotation of the pivot connection means by which each leaf of said set of leaves is connected to a branch may be perpendicular to the plane in which the leaf associated with that axis rotation extends.
  • Each leaf of said leaf assembly may extend substantially perpendicular to the branch to which it is attached when the umbrella is in the deployed configuration, and each leaf of said leaf assembly may extend substantially parallel to the branch to which it is attached when the umbrella is in the retracted configuration.
  • At least a portion of the leaves of said set of leaves of the parasol can form an openwork screen when the parasol is in the deployed configuration, in particular said screen having a generally conical or truncated cone shape.
  • Each branch can be connected to the foot by a pivot connection means around a second axis of rotation, each branch pivoting around its second axis of rotation when the umbrella moves from its deployed configuration to its retracted configuration.
  • the parasol may comprise a synchronization means configured such that a pivoting of a branch about its second axis of rotation causes a pivoting of the leaves of said set of leaves connected to this branch about their respective axis of rotation.
  • Each branch may comprise an upper face and a lower face opposite the upper face, the leaves connected to the same branch being connected alternately either to the upper face or to the lower face of said branch.
  • Each branch may comprise a first end through which it is connected to the foot and a second free end.
  • Each leaf may comprise a first end through which it is connected to a branch and a second free end, the leaves connected to the same branch comprising a length between their first end and their second end increasing as a function of their distance from the first end of the branch to which they are connected.
  • FIG 1 illustrates in perspective view a parasol 1 according to an embodiment of the invention.
  • the parasol 1 is in the deployed configuration.
  • the parasol 1 comprises a foot 2 by means of which it rests on the ground, and a protective part 3 intended to produce shade. It is assumed that the parasol 1 rests on horizontal ground.
  • the foot 2 comprises in particular a base 4 intended to rest on the ground, a mast 5 vertical or slightly inclined relative to a vertical axis, and an arm 6 connecting the protective part 3 to the mast 5.
  • the protective part 3 is thus suspended above the ground by means of the arm 6.
  • the foot 2 therefore extends on one side of the protective part 3.
  • the parasol can thus be described as an "offset” parasol.
  • the invention could also be declined with a so-called “straight” parasol, that is to say a parasol whose protective part is supported from below, in particular with a central foot.
  • the arm 6 may in particular comprise a curved shape so as to avoid any interference with the protective part 3. This allows the use of a relatively short mast 5 and limits the leverage effect produced by the protective part 3 on the foot 2 and which would tend to tip the parasol 1.
  • the arm 6 is extended by a dome 7 arranged substantially in the center of the protective part 3, on an upper face thereof.
  • the dome 7 may have substantially the shape of a disk.
  • the protective part 3 may have a generally circular outline. Alternatively, the shape of this outline could be different, for example a square or rectangular shape.
  • the protective part 3 is capable of producing a shadow 8 whose position and shape also depends on the position of the sun relative to the parasol.
  • the protective part 3 extends generally horizontally, that is, the outline of the protective part extends in a horizontal plane.
  • the protective part 3 can be tilted, so as to adapt the position of the shade 8.
  • the arm 6 can be articulated on the mast 5 to allow a certain inclination of the protective part 3.
  • the parasol 1 is mobile, reversibly, between a deployed configuration, illustrated in particular on the figures 1 And 2 , and a retracted configuration, or in other words a folded configuration, illustrated in the figure 3 .
  • the protective part 3 comprises a set of branches 9 extending radially from a center C of the protective part.
  • the branches 9 form radii of the protective part 3.
  • Each branch 9 comprises a first end 9A, by means of which it is connected to the foot 2, and a second free end 9B.
  • the branches 9 and the foot 2 form a rigid structure of the parasol.
  • the branches 9 and the foot 2 may, for example, be made of metal.
  • Each branch 9 carries a set of leaves 10.
  • Each leaf 10 comprises a first end 10A by means of which it is connected to a branch 9, and a second free end 10B.
  • the branches 9 and the leaves 10 produce the shade 8.
  • the parasol 1 occupies a reduced volume which facilitates its storage and reduces its wind resistance.
  • each branch 9 is connected to the foot 2 by a pivot connection means around an axis of rotation R2 (identified on the figure 3 ).
  • the rotation axis R2 extends substantially horizontally, at its first end 9A.
  • Each rotational articulation means may comprise, for example, a hinge.
  • Each hinge may comprise a first part fixed to the arm 6 or to the dome 7, and a second part fixed to a branch 9.
  • Each branch 9 is thus able to pivot about its rotation axis R2 between an at least roughly horizontal position, corresponding to the deployed configuration of the parasol, and an at least roughly vertical position, corresponding to the retracted configuration of the parasol.
  • the dome 7 extends above said articulation means and thus protects them from bad weather.
  • the amplitude of rotation of each branch 9 around its axis of rotation R2 between the deployed configuration and the retracted configuration of the parasol may be for example between 45° and 90° inclusive, preferably between 60° and 90° inclusive.
  • each leaf 10 extends substantially perpendicular to the branch 9 to which it is attached when the parasol is in the deployed configuration.
  • an axis X1 can be defined as the axis passing through the two ends 10A and 10B of this sheet.
  • the axis X2 can be defined as the axis in which the branch extends, that is to say the axis passing through the two ends 9A and 9B of said branch.
  • substantially perpendicular it is understood that the axis X1 of each sheet can form with the axis X2 an angle A1 of between 60° and 120° inclusive, preferably between 70° and 110° inclusive.
  • each branch carries at least one leaf projecting towards each of the two adjacent branches, preferably at least two leaves projecting towards each of the two adjacent branches.
  • the axes X1 of the leaves projecting from the same side of the same branch may be parallel to each other, at least when the parasol is in the deployed configuration, or even also when the parasol is in the retracted configuration.
  • At least a portion of the leaves 10 thus forms a first screen when the parasol is in the deployed configuration.
  • This first screen has a generally conical or truncated shape.
  • the apex of the conical or truncated shape corresponds substantially to the center C.
  • the opening angle of the conical or truncated shape may be for example greater than or equal to 135°. In one embodiment, the opening angle of the conical or truncated shape could approach, or even reach 180°, so that the screen formed by said leaves would extend in a plane.
  • the parasol 1 may comprise several superimposed screens, each screen being formed by a set of leaves.
  • the screen formed by the set of sheets 10 is perforated, that is to say that it comprises openings 11 through which rays of sunlight can pass. These openings 11 are formed by the spaces existing between the different sheets 10. These openings 11 also allow a certain circulation of the air volume under the protective part 3, which makes it possible to avoid the formation of a heat bubble. Since the air can circulate through the screen by passing between the sheets 10, the parasol has a significantly lower wind resistance than an equivalent parasol whose protective part would be formed by a canvas. Since the wind resistance is reduced, the parasol is less likely to fly away and the base 4 of the foot 2 can be lighter. The base 4 therefore requires a smaller quantity of material. It is therefore more economical and less bulky.
  • the light rays passing through the openings 11 produce illuminated areas 12 within the shade 8. These illuminated areas are not annoying because they are very small. On the contrary, they produce a soothing optical effect.
  • the shade produced by the parasol 1 is similar to the shade produced by a tree.
  • the leaves 10 are likely to be animated by a slight movement, for example under the effect of the wind, which has the effect of moving the illuminated areas 12. This avoids potential burns that could occur if the same surface remained exposed for too long in an illuminated area 12.
  • Each sheet 10 may be made of opaque material and may extend in a plane.
  • the sheets 10 connected to the same branch 9 may extend parallel to the same plane.
  • Each sheet 10 may be an ovoid or elliptical shaped plate.
  • the two ends 10A and 10B of each sheet may optionally be pointed, thus recalling the shape of a natural tree leaf.
  • any other leaf shape could be envisaged, for example a circular shape, a polygonal shape, or even a flower petal shape.
  • Each sheet may comprise a constant thickness, for example less than or equal to 5 mm, in particular between 1 mm and 3 mm inclusive.
  • Each sheet may comprise sufficient flexibility to deform slightly under the effect of the wind and/or under the effect of its own weight when it is held by one of its ends.
  • Each leaf can thus be naturally animated by a certain movement which will tend to slightly move the shadow 8 and to create a flow of refreshing air.
  • Each leaf is nevertheless sufficiently rigid not to bend or sag when it is held by one of its ends.
  • Each sheet 10 may for example comprise at least one wooden slat.
  • Different types of wood may be considered, which makes it possible to vary the appearance of the parasol.
  • the grain of the wood may be visible, which gives a unique appearance to each parasol.
  • the wooden slats may optionally be varnished in order to be more resistant to the sun.
  • the sun's rays may optionally change the appearance of the wooden slats, which gives a patina and an original aesthetic appearance to the parasol.
  • wood is a natural and particularly ecological material.
  • the sheets 10 do not comprise synthetic fibres, the manufacture of which is more polluting.
  • the conical or truncated cone-shaped screen mentioned above is thus formed by assembling a set of flat sheets.
  • the sheets therefore extend mainly into the surface of the screen.
  • the surface of each sheet 10 is thus effectively used to block the sun's rays.
  • Each sheet thus has a large occulting surface for a reasonable weight.
  • each sheet 10 is connected to a branch 9 by a pivot connection means 13 about an axis of rotation R1.
  • the axis of rotation R1 extends substantially at the level of the first end 10A of each sheet.
  • Each sheet 10 can thus adopt a different orientation relative to the branch 9 to which it is connected. It is thus possible to envisage an individual pivoting of each sheet 10 about its axis of rotation R1 when the umbrella moves from its deployed configuration to its retracted configuration.
  • each leaf 10 can extend substantially parallel to the branch 9 to which it is connected when the parasol is in the retracted configuration.

  • the leaves 10 can overlap at least partially with each other and/or overlap with the branch 9 to which they are connected. Conversely, when the parasol is in the deployed configuration, the leaves 10 connected to the same branch do not overlap with each other, nor do they overlap with the branch 9. This optimizes the protective surface provided by a branch equipped with its leaves.
  • a leaf 10 can thus pivot by at least 30°, preferably by at least 45°, about its axis of rotation R1 when the parasol passes from its deployed configuration to its retracted configuration.

Description

Domaine Technique de l'inventionTechnical field of the invention

L'invention concerne un parasol.The invention relates to a parasol.

Etat de la technique antérieureState of the prior art

Pour se protéger du soleil, on utilise classiquement un parasol comprenant un pied, un ensemble de branches s'étendant depuis le pied, et une toile opaque fixée auxdites branches. Les branches sont en général articulées par rapport au pied de sorte à rendre le parasol mobile entre une configuration déployée et une configuration rétractée. En configuration déployée, la toile forme un écran destiné à produire de l'ombre. En configuration rétractée, le parasol est le plus compact possible, de manière à pouvoir être rangé et/ou de manière à offrir une faible prise au vent.To protect oneself from the sun, a parasol is conventionally used comprising a base, a set of branches extending from the base, and an opaque canvas attached to said branches. The branches are generally articulated relative to the base so as to make the parasol mobile between an extended configuration and a retracted configuration. In the extended configuration, the canvas forms a screen intended to produce shade. In the retracted configuration, the parasol is as compact as possible, so as to be able to be stored and/or so as to offer little wind resistance.

Un tel parasol présente l'inconvénient d'emprisonner une bulle de chaleur sous la toile car la toile empêche l'air de circuler librement et notamment de s'échapper vers le haut. Un tel parasol présente également une prise au vent importante. Il requiert donc un moyen d'ancrage dans le sol ou un leste très important pour ne pas se faire emporter en présence de vent.Such a parasol has the disadvantage of trapping a bubble of heat under the canvas because the canvas prevents air from circulating freely and in particular from escaping upwards. Such a parasol also has a significant wind resistance. It therefore requires a means of anchoring in the ground or very significant ballast to prevent it from being carried away in the presence of wind.

Pour remédier à ces inconvénients, il a été proposé de fournir des parasols inspirés de la nature et reproduisant sensiblement l'ombre produite par un arbre. Le document US2005028853A1 divulgue par exemple un tel parasol. Un tel parasol permet certes d'obtenir une meilleure circulation de l'air dans un volume ombragé, cependant il est très lourd et volumineux et produit relativement peu d'ombre comparativement à ses dimensions et à son poids. En particulier, un tel parasol demeure très volumineux et conserve une prise au vent importante même lorsqu'il est en configuration rétractée.To overcome these drawbacks, it was proposed to provide parasols inspired by nature and substantially reproducing the shade produced by a tree. The document US2005028853A1 discloses for example such a parasol. Such a parasol certainly allows for better air circulation in a shaded volume, however it is very heavy and bulky and produces relatively little shade compared to its dimensions and weight. In particular, such a parasol remains very bulky and maintains significant wind resistance even when in the retracted configuration.

Présentation de l'inventionPresentation of the invention

Le but de l'invention est de fournir un parasol remédiant aux inconvénients ci-dessus et améliorant les parasols connus de l'art antérieur.The aim of the invention is to provide a parasol which overcomes the above drawbacks and improves the parasols known from the prior art.

Plus précisément, un premier objet de l'invention est un parasol apte à produire une grande surface ombragée, qui favorise la circulation de l'air au niveau de la surface ombragée, et qui puisse passer dans une configuration rétractée particulièrement compacte.More specifically, a first object of the invention is a parasol capable of producing a large shaded surface, which promotes air circulation at the shaded surface, and which can pass into a particularly compact retracted configuration.

Résumé de l'inventionSummary of the invention

L'invention se rapporte à un parasol comprenant :

  • un pied,
  • un ensemble de branches, chaque branche étant liée au pied, et
  • un ensemble de feuilles, chaque feuille dudit ensemble de feuilles étant destinée à produire de l'ombre, chaque feuille dudit ensemble de feuilles étant liée à une branche par un moyen de liaison pivot autour d'un axe de rotation.
The invention relates to a parasol comprising:
  • a foot,
  • a set of branches, each branch being attached to the foot, and
  • a set of leaves, each leaf of said set of leaves being intended to produce shade, each leaf of said set of leaves being linked to a branch by a pivot connection means about an axis of rotation.

Le parasol peut être mobile entre une configuration déployée et une configuration rétractée, chaque feuille dudit ensemble de feuilles pivotant autour de son axe de rotation lorsque le parasol passe de sa configuration déployée à sa configuration rétractée.The umbrella may be movable between an extended configuration and a retracted configuration, each leaf of said leaf assembly pivoting about its axis of rotation as the umbrella moves from its extended configuration to its retracted configuration.

Chaque feuille dudit ensemble de feuilles peut s'étendre sensiblement parallèlement à un plan, et l'axe de rotation du moyen de liaison pivot par lequel chaque feuille dudit ensemble de feuilles est reliée à une branche peut être perpendiculaire au plan dans lequel la feuille associée à cet axe de rotation s'étend.Each leaf of said set of leaves may extend substantially parallel to a plane, and the axis of rotation of the pivot connection means by which each leaf of said set of leaves is connected to a branch may be perpendicular to the plane in which the leaf associated with that axis rotation extends.

Chaque feuille dudit ensemble de feuilles peut s'étendre sensiblement perpendiculairement à la branche à laquelle elle est liée lorsque le parasol est en configuration déployée, et chaque feuille dudit ensemble de feuilles peut s'étendre sensiblement parallèlement à la branche à laquelle elle est liée lorsque le parasol est en configuration rétractée.Each leaf of said leaf assembly may extend substantially perpendicular to the branch to which it is attached when the umbrella is in the deployed configuration, and each leaf of said leaf assembly may extend substantially parallel to the branch to which it is attached when the umbrella is in the retracted configuration.

Au moins une partie des feuilles dudit ensemble de feuilles du parasol peut former un écran ajouré lorsque le parasol est en configuration déployée, notamment ledit écran présentant une forme globalement conique ou tronconique.At least a portion of the leaves of said set of leaves of the parasol can form an openwork screen when the parasol is in the deployed configuration, in particular said screen having a generally conical or truncated cone shape.

Chaque branche peut être liée au pied par un moyen de liaison pivot autour d'un deuxième axe de rotation, chaque branche pivotant autour de son deuxième axe de rotation lorsque le parasol passe de sa configuration déployée à sa configuration rétractée.Each branch can be connected to the foot by a pivot connection means around a second axis of rotation, each branch pivoting around its second axis of rotation when the umbrella moves from its deployed configuration to its retracted configuration.

Le parasol peut comprendre un moyen de synchronisation configuré de sorte qu'un pivotement d'une branche autour de son deuxième axe de rotation entraîne un pivotement des feuilles dudit ensemble de feuilles reliées à cette branche autour de leur axe de rotation respectif.The parasol may comprise a synchronization means configured such that a pivoting of a branch about its second axis of rotation causes a pivoting of the leaves of said set of leaves connected to this branch about their respective axis of rotation.

Description détailléeDetailed description

La figure 1 illustre en vue de perspective un parasol 1 selon un mode de réalisation de l'invention. Le parasol 1 est en configuration déployée. Le parasol 1 comprend un pied 2 par l'intermédiaire duquel il repose sur le sol, et une partie protectrice 3 destinée à produire de l'ombre. On suppose que le parasol 1 repose sur un sol horizontal. Le pied 2 comprend notamment un socle 4 destiné à prendre appui sur le sol, un mât 5 vertical ou légèrement incliné par rapport à un axe vertical, et un bras 6 reliant la partie protectrice 3 au mât 5.There figure 1 illustrates in perspective view a parasol 1 according to an embodiment of the invention. The parasol 1 is in the deployed configuration. The parasol 1 comprises a foot 2 by means of which it rests on the ground, and a protective part 3 intended to produce shade. It is assumed that the parasol 1 rests on horizontal ground. The foot 2 comprises in particular a base 4 intended to rest on the ground, a mast 5 vertical or slightly inclined relative to a vertical axis, and an arm 6 connecting the protective part 3 to the mast 5.

La partie protectrice 3 est ainsi suspendue au-dessus du sol par l'intermédiaire du bras 6. Le pied 2 s'étend donc sur un côté de la partie protectrice 3. Le parasol peut ainsi être qualifié de parasol "déporté". En variante, l'invention pourrait aussi être déclinée avec un parasol dit "droit", c'est-à-dire un parasol dont la partie protectrice est supportée par le dessous, notamment avec un pied central.The protective part 3 is thus suspended above the ground by means of the arm 6. The foot 2 therefore extends on one side of the protective part 3. The parasol can thus be described as an "offset" parasol. Alternatively, the invention could also be declined with a so-called "straight" parasol, that is to say a parasol whose protective part is supported from below, in particular with a central foot.

Le bras 6 peut notamment comprendre une forme courbée de manière à éviter toute interférence avec la partie protectrice 3. Ceci permet l'utilisation d'un mât 5 relativement court et limite l'effet de levier produit par la partie protectrice 3 sur le pied 2 et qui tendrait à faire basculer le parasol 1.The arm 6 may in particular comprise a curved shape so as to avoid any interference with the protective part 3. This allows the use of a relatively short mast 5 and limits the leverage effect produced by the protective part 3 on the foot 2 and which would tend to tip the parasol 1.

Le bras 6 est prolongé par une coupole 7 agencée sensiblement au centre de la partie protectrice 3, sur une face supérieure de celle-ci. La coupole 7 peut avoir sensiblement la forme d'un disque.The arm 6 is extended by a dome 7 arranged substantially in the center of the protective part 3, on an upper face thereof. The dome 7 may have substantially the shape of a disk.

La partie protectrice 3 peut avoir un contour de forme globalement circulaire. En variante, la forme de ce contour pourrait être différente par exemple une forme carrée ou rectangulaire. La partie protectrice 3 est apte à produire une ombre 8 dont la position et la forme dépend également de la position du soleil relativement au parasol. Sur la figure 1, la partie protectrice 3 s'étend globalement horizontalement, c'est-à-dire que le contour de la partie protectrice s'étend dans un plan horizontal. Comme cela est illustré sur la figure 2, la partie protectrice 3 peut être inclinable, de manière à adapter la position de l'ombre 8. Le bras 6 peut être articulé sur le mât 5 pour permettre une certaine inclinaison de la partie protectrice 3.The protective part 3 may have a generally circular outline. Alternatively, the shape of this outline could be different, for example a square or rectangular shape. The protective part 3 is capable of producing a shadow 8 whose position and shape also depends on the position of the sun relative to the parasol. On the figure 1 , the protective part 3 extends generally horizontally, that is, the outline of the protective part extends in a horizontal plane. As illustrated in the figure 2 , the protective part 3 can be tilted, so as to adapt the position of the shade 8. The arm 6 can be articulated on the mast 5 to allow a certain inclination of the protective part 3.

Par ailleurs, le parasol 1 est mobile, de manière réversible, entre une configuration déployée, illustrée notamment sur les figures 1 et 2, et une configuration rétractée, ou autrement dit une configuration repliée, illustrée sur la figure 3.Furthermore, the parasol 1 is mobile, reversibly, between a deployed configuration, illustrated in particular on the figures 1 And 2 , and a retracted configuration, or in other words a folded configuration, illustrated in the figure 3 .

La partie protectrice 3 comprend un ensemble de branches 9 s'étendant radialement depuis un centre C de la partie protectrice. Autrement dit, les branches 9 forment des rayons de la partie protectrice 3. Chaque branche 9 comprend une première extrémité 9A, par l'intermédiaire de laquelle elle est reliée au pied 2, et une deuxième extrémité 9B libre. Les branches 9 et le pied 2 forment une structure rigide du parasol. Les branches 9 et le pied 2 peuvent, par exemple, être en métal.The protective part 3 comprises a set of branches 9 extending radially from a center C of the protective part. In other words, the branches 9 form radii of the protective part 3. Each branch 9 comprises a first end 9A, by means of which it is connected to the foot 2, and a second free end 9B. The branches 9 and the foot 2 form a rigid structure of the parasol. The branches 9 and the foot 2 may, for example, be made of metal.

Chaque branche 9 porte un ensemble de feuilles 10. Chaque feuille 10 comprend une première extrémité 10A par l'intermédiaire de laquelle elle est reliée à une branche 9, et une deuxième extrémité libre 10B. En configuration déployée, les branches 9 et les feuilles 10 produisent l'ombre 8. En configuration rétractée, le parasol 1 occupe un volume réduit ce qui facilite son rangement et réduit sa prise au vent.Each branch 9 carries a set of leaves 10. Each leaf 10 comprises a first end 10A by means of which it is connected to a branch 9, and a second free end 10B. In the deployed configuration, the branches 9 and the leaves 10 produce the shade 8. In the retracted configuration, the parasol 1 occupies a reduced volume which facilitates its storage and reduces its wind resistance.

Pour permettre le passage du parasol de sa configuration déployée vers sa configuration rétractée ou inversement, chaque branche 9 est liée au pied 2 par un moyen de liaison pivot autour d'un axe de rotation R2 (identifié sur la figure 3). Pour chaque branche 9, l'axe de rotation R2 s'étend sensiblement horizontalement, au niveau de sa première extrémité 9A. Chaque moyen d'articulation en rotation peut comprendre par exemple une charnière. Chaque charnière peut comprendre une première partie fixée au bras 6 ou à la coupole 7, et une deuxième partie fixée à une branche 9. Chaque branche 9 est ainsi apte à pivoter autour de son axe de rotation R2 entre une position au moins grossièrement horizontale, correspondant à la configuration déployée du parasol, et une position au moins grossièrement verticale, correspondant à la configuration rétractée du parasol. Avantageusement, la coupole 7 s'étend au-dessus desdits moyens d'articulation et les protège ainsi des intempéries.To allow the parasol to move from its deployed configuration to its retracted configuration or vice versa, each branch 9 is connected to the foot 2 by a pivot connection means around an axis of rotation R2 (identified on the figure 3 ). For each branch 9, the rotation axis R2 extends substantially horizontally, at its first end 9A. Each rotational articulation means may comprise, for example, a hinge. Each hinge may comprise a first part fixed to the arm 6 or to the dome 7, and a second part fixed to a branch 9. Each branch 9 is thus able to pivot about its rotation axis R2 between an at least roughly horizontal position, corresponding to the deployed configuration of the parasol, and an at least roughly vertical position, corresponding to the retracted configuration of the parasol. Advantageously, the dome 7 extends above said articulation means and thus protects them from bad weather.

L'amplitude de rotation de chaque branche 9 autour de son axe de rotation R2 entre la configuration déployée et la configuration rétractée du parasol peut être par exemple comprise entre 45° et 90° inclus, de préférence entre 60° et 90° inclus.The amplitude of rotation of each branch 9 around its axis of rotation R2 between the deployed configuration and the retracted configuration of the parasol may be for example between 45° and 90° inclusive, preferably between 60° and 90° inclusive.

Comme cela est visible sur la figure 4, chaque feuille 10 s'étend sensiblement perpendiculairement à la branche 9 à laquelle elle est liée lorsque le parasol est en configuration déployée. Pour une feuille donnée, on peut définir un axe X1 comme l'axe passant par les deux extrémités 10A et 10B de cette feuille. Pour une branche donnée, on peut définir l'axe X2 comme l'axe dans lequel la branche s'étend, c'est-à-dire l'axe passant par les deux extrémité 9A et 9B de ladite branche. Par "sensiblement perpendiculairement", on comprend que l'axe X1 de chaque feuille peut former avec l'axe X2 un angle A1 compris entre 60° et 120° inclus, de préférence entre 70° et 110° inclus.As can be seen on the figure 4 , each leaf 10 extends substantially perpendicular to the branch 9 to which it is attached when the parasol is in the deployed configuration. For a given leaf, an axis X1 can be defined as the axis passing through the two ends 10A and 10B of this sheet. For a given branch, the axis X2 can be defined as the axis in which the branch extends, that is to say the axis passing through the two ends 9A and 9B of said branch. By "substantially perpendicular", it is understood that the axis X1 of each sheet can form with the axis X2 an angle A1 of between 60° and 120° inclusive, preferably between 70° and 110° inclusive.

Avantageusement, chaque branche porte au moins une feuille saillante en direction de chacune des deux branches adjacentes, de préférence au moins deux feuilles saillantes en direction de chacune des deux branches adjacentes. Les axes X1 des feuilles saillantes depuis un même côté d'une même branche peuvent être parallèles entre eux, au moins lorsque le parasol est en configuration déployée, voire également lorsque le parasol est en configuration rétractée.Advantageously, each branch carries at least one leaf projecting towards each of the two adjacent branches, preferably at least two leaves projecting towards each of the two adjacent branches. The axes X1 of the leaves projecting from the same side of the same branch may be parallel to each other, at least when the parasol is in the deployed configuration, or even also when the parasol is in the retracted configuration.

Au moins une partie des feuilles 10 forme ainsi un premier écran lorsque le parasol est en configuration déployée. Ce premier écran présente une forme globalement conique ou tronconique. Le sommet de la forme conique ou tronconique correspond sensiblement au centre C. L'angle d'ouverture de la forme conique ou tronconique peut être par exemple supérieur ou égal à 135°. Dans un mode de réalisation, l'angle d'ouverture de la forme conique ou tronconique pourrait s'approcher, voire même atteindre 180°, si bien que l'écran formé par lesdites feuilles s'étendrait dans un plan. Comme nous le verrons plus en détail par la suite, le parasol 1 peut comprendre plusieurs écrans superposés, chaque écran étant formé par un ensemble de feuilles.At least a portion of the leaves 10 thus forms a first screen when the parasol is in the deployed configuration. This first screen has a generally conical or truncated shape. The apex of the conical or truncated shape corresponds substantially to the center C. The opening angle of the conical or truncated shape may be for example greater than or equal to 135°. In one embodiment, the opening angle of the conical or truncated shape could approach, or even reach 180°, so that the screen formed by said leaves would extend in a plane. As we will see in more detail later, the parasol 1 may comprise several superimposed screens, each screen being formed by a set of leaves.

L'écran formé par l'ensemble de feuilles 10 est ajouré, c'est-à-dire qu'il comprend des ouvertures 11 par lesquelles des rayons de soleil peuvent passer. Ces ouvertures 11 sont formées par les espaces existant entre les différentes feuilles 10. Ces ouvertures 11 permettent également une certaine circulation du volume d'air sous la partie protectrice 3, ce qui permet d'éviter la formation d'une bulle de chaleur. Comme l'air peut circuler au travers de l'écran en passant entre les feuilles 10, le parasol présente une prise au vent nettement plus faible qu'un parasol équivalent dont la partie protectrice serait formée par une toile. Comme la prise au vent est réduite, le parasol risque moins facilement de s'envoler et le socle 4 du pied 2 peut être moins lourd. Le socle 4 requiert donc une plus faible quantité de matériau. Il est donc plus économique et moins encombrant.The screen formed by the set of sheets 10 is perforated, that is to say that it comprises openings 11 through which rays of sunlight can pass. These openings 11 are formed by the spaces existing between the different sheets 10. These openings 11 also allow a certain circulation of the air volume under the protective part 3, which makes it possible to avoid the formation of a heat bubble. Since the air can circulate through the screen by passing between the sheets 10, the parasol has a significantly lower wind resistance than an equivalent parasol whose protective part would be formed by a canvas. Since the wind resistance is reduced, the parasol is less likely to fly away and the base 4 of the foot 2 can be lighter. The base 4 therefore requires a smaller quantity of material. It is therefore more economical and less bulky.

Les rayons lumineux passant par les ouvertures 11 produisent des zones éclairées 12 au sein de l'ombre 8. Ces zones éclairées ne sont pas gênantes car elles présentent de très faibles dimensions. Au contraire, elles produisent un effet optique apaisant. L'ombre produite par le parasol 1 est similaire à l'ombre produite par un arbre. De plus, les feuilles 10 sont susceptibles d'être animées d'un léger mouvement, par exemple sous l'effet du vent, ce qui a pour effet de déplacer les zones éclairées 12. On évite ainsi de potentielles brulures qui pourraient se produire si une même surface restait exposée trop longtemps dans une zone éclairée 12.The light rays passing through the openings 11 produce illuminated areas 12 within the shade 8. These illuminated areas are not annoying because they are very small. On the contrary, they produce a soothing optical effect. The shade produced by the parasol 1 is similar to the shade produced by a tree. In addition, the leaves 10 are likely to be animated by a slight movement, for example under the effect of the wind, which has the effect of moving the illuminated areas 12. This avoids potential burns that could occur if the same surface remained exposed for too long in an illuminated area 12.

Chaque feuille 10 peut être fabriquée en matériau opaque et peut s'étendre dans un plan. Les feuilles 10 liées à une même branche 9 peuvent s'étendre parallèlement à un même plan. Chaque feuille 10 peut être une plaque de forme ovoïde ou elliptique. Les deux extrémités 10A et 10B de chaque feuille peuvent éventuellement être pointues, rappelant ainsi la forme d'une feuille d'arbre naturelle. En variante, toute autre forme de feuille pourrait être envisagée, par exemple une forme circulaire, une forme polygonale, ou encore une forme de pétale de fleur. Chaque feuille peut comprendre une épaisseur constante, par exemple inférieure ou égale à 5mm, notamment comprise entre 1 mm et 3mm inclus. Chaque feuille peut comprendre une souplesse suffisante pour se déformer légèrement sous l'effet du vent et/ou sous l'effet de son propre poids lorsqu'elle est maintenue par une de ses extrémités. Chaque feuille peut ainsi être naturellement animée d'un certain mouvement qui aura tendance à déplacer légèrement l'ombre 8 et à créer un flux d'air rafraichissant. Chaque feuille est néanmoins suffisamment rigide pour ne pas se plier ou s'affaisser lorsqu'elle est maintenue par une de ses extrémités.Each sheet 10 may be made of opaque material and may extend in a plane. The sheets 10 connected to the same branch 9 may extend parallel to the same plane. Each sheet 10 may be an ovoid or elliptical shaped plate. The two ends 10A and 10B of each sheet may optionally be pointed, thus recalling the shape of a natural tree leaf. Alternatively, any other leaf shape could be envisaged, for example a circular shape, a polygonal shape, or even a flower petal shape. Each sheet may comprise a constant thickness, for example less than or equal to 5 mm, in particular between 1 mm and 3 mm inclusive. Each sheet may comprise sufficient flexibility to deform slightly under the effect of the wind and/or under the effect of its own weight when it is held by one of its ends. Each leaf can thus be naturally animated by a certain movement which will tend to slightly move the shadow 8 and to create a flow of refreshing air. Each leaf is nevertheless sufficiently rigid not to bend or sag when it is held by one of its ends.

Chaque feuille 10 peut par exemple comprendre au moins une lame de bois. Différentes essences de bois peuvent être envisagées, ce qui permet de faire varier l'aspect du parasol. Le veinage du bois peut être apparent, ce qui donne un aspect unique à chaque parasol. Les lames de bois peuvent éventuellement être vernies afin d'être plus résistantes au soleil. Les rayons du soleil peuvent éventuellement modifier l'apparence des lames de bois, ce qui confère une patine et un aspect esthétique original au parasol. De plus, le bois est un matériau naturel et particulièrement écologique. Les feuilles 10 ne comprennent pas de fibres synthétiques dont la fabrication est plus polluante.Each sheet 10 may for example comprise at least one wooden slat. Different types of wood may be considered, which makes it possible to vary the appearance of the parasol. The grain of the wood may be visible, which gives a unique appearance to each parasol. The wooden slats may optionally be varnished in order to be more resistant to the sun. The sun's rays may optionally change the appearance of the wooden slats, which gives a patina and an original aesthetic appearance to the parasol. In addition, wood is a natural and particularly ecological material. The sheets 10 do not comprise synthetic fibres, the manufacture of which is more polluting.

L'écran de forme conique ou tronconique mentionné précédemment est donc formé par l'assemblage d'un ensemble de feuilles planes. Les feuilles s'étendent donc principalement dans la surface de l'écran. Contrairement à des feuilles tridimensionnelles, la surface de chaque feuille 10 est donc efficacement mise à profit pour bloquer les rayons du soleil. Chaque feuille présente ainsi une grande surface occultante pour un poids raisonnable.The conical or truncated cone-shaped screen mentioned above is thus formed by assembling a set of flat sheets. The sheets therefore extend mainly into the surface of the screen. Unlike three-dimensional sheets, the surface of each sheet 10 is thus effectively used to block the sun's rays. Each sheet thus has a large occulting surface for a reasonable weight.

Avantageusement, chaque feuille 10 est liée à une branche 9 par un moyen de liaison pivot 13 autour d'un axe de rotation R1. L'axe de rotation R1 s'étend sensiblement au niveau de la première extrémité 10A de chaque feuille. Chaque feuille 10 peut ainsi adopter une orientation différente relativement à la branche 9 à laquelle elle est liée. On peut ainsi envisager un pivotement individuel de chaque feuille 10 autour de son axe de rotation R1 lorsque le parasol passe de sa configuration déployée à sa configuration rétractée.Advantageously, each sheet 10 is connected to a branch 9 by a pivot connection means 13 about an axis of rotation R1. The axis of rotation R1 extends substantially at the level of the first end 10A of each sheet. Each sheet 10 can thus adopt a different orientation relative to the branch 9 to which it is connected. It is thus possible to envisage an individual pivoting of each sheet 10 about its axis of rotation R1 when the umbrella moves from its deployed configuration to its retracted configuration.

Comme cela est illustré sur la figure 5, chaque feuille 10 peut s'étendre sensiblement parallèlement à la branche 9 à laquelle elle est liée lorsque le parasol est en configuration rétractée. Par "sensiblement parallèlement", on comprend que l'angle A1 formé entre les axes X1 et X2 est strictement inférieur à 30°, voire strictement inférieur à 20°.As illustrated in the figure 5 , each leaf 10 can extend substantially parallel to the branch 9 to which it is connected when the parasol is in the retracted configuration. By "substantially parallel", it is understood that the angle A1 formed between the axes X1 and X2 is strictly less than 30°, or even strictly less than 20°.

Lorsque le parasol est en configuration rétractée, les feuilles 10 peuvent se superposer au moins partiellement entre elles et/ou se superposer à la branche 9 à laquelle elles sont liées. Inversement, lorsque le parasol est en configuration déployée, les feuilles 10 liées à une même branche ne se superposent pas entre elles, et ne superposent pas non plus à la branche 9. On optimise ainsi la surface de protection conférée par une branche équipée de ses feuilles.When the parasol is in the retracted configuration, the leaves 10 can overlap at least partially with each other and/or overlap with the branch 9 to which they are connected. Conversely, when the parasol is in the deployed configuration, the leaves 10 connected to the same branch do not overlap with each other, nor do they overlap with the branch 9. This optimizes the protective surface provided by a branch equipped with its leaves.

Une feuille 10 peut ainsi pivoter d'au moins 30°, de préférence d'au moins 45°, autour de son axe de rotation R1 lorsque le parasol passe de sa configuration déployée à sa configuration rétractée. Ainsi, bien que chaque feuille présente une surface occultante importante, chaque branche 9 pourvue de ses feuilles 10 occupe un volume relativement faible lorsque le parasol est en configuration rétractée. Le parasol est donc peu encombrant et offre une faible prise au vent lorsqu'il est en configuration rétractée. Les feuilles 10 ne sont pas pliées ou déformées pour faire passer le parasol en configuration rétractée. On évite ainsi de les endommager au fil de l'utilisation du parasol.A leaf 10 can thus pivot by at least 30°, preferably by at least 45°, about its axis of rotation R1 when the parasol passes from its deployed configuration to its retracted configuration. Thus, although each leaf has a large occulting surface, each branch 9 provided with its leaves 10 occupies a relatively small volume when the parasol is in the retracted configuration. The parasol is therefore compact and offers little wind resistance when it is in the retracted configuration. The leaves 10 are not folded or deformed to move the parasol into the retracted configuration. This avoids damaging them during use of the parasol.

De préférence, le moyen de liaison pivot 13 autour de l'axe de rotation R1 de chaque feuille est bloqué lorsque le parasol est en configuration déployée de manière à garantir un positionnement stable de chaque feuille.Preferably, the pivot connection means 13 around the axis of rotation R1 of each leaf is blocked when the parasol is in configuration deployed in such a way as to ensure stable positioning of each sheet.

L'axe de rotation R1 du moyen de liaison pivot 13 par lequel chaque feuille 10 est reliée à une branche 9 est perpendiculaire au plan dans lequel la feuille associée à cet axe de rotation s'étend. Par exemple, si une feuille 10 s'étend horizontalement, alors l'axe de rotation R1 associé à cette feuille est vertical. Chaque feuille 10 pivote donc autour de son axe de rotation R1 dans le plan dans lequel elle s'étend. Les axes de rotations R1 des différentes feuilles liées à une même branche sont de préférence parallèles entre eux.The axis of rotation R1 of the pivot connection means 13 by which each sheet 10 is connected to a branch 9 is perpendicular to the plane in which the sheet associated with this axis of rotation extends. For example, if a sheet 10 extends horizontally, then the axis of rotation R1 associated with this sheet is vertical. Each sheet 10 therefore pivots about its axis of rotation R1 in the plane in which it extends. The axes of rotation R1 of the different sheets connected to the same branch are preferably parallel to each other.

Dans un mode de réalisation, le moyen de liaison pivot 13 reliant une feuille 10 à une branche 9 peut comprendre un palier lisse, par exemple un palier lisse obtenu par la coopération de deux surfaces circulaires et concentriques. Alternativement, le moyen de liaison pivot 13 pourrait comprendre un roulement, notamment un roulement à billes.In one embodiment, the pivot connection means 13 connecting a sheet 10 to a branch 9 may comprise a plain bearing, for example a plain bearing obtained by the cooperation of two circular and concentric surfaces. Alternatively, the pivot connection means 13 could comprise a bearing, in particular a ball bearing.

Chaque branche 9 comprend une face supérieure 9s (visible par exemple sur la figure 3) et une face inférieure 9i (visible par exemple sur la figure 2) opposée à la face supérieure 9s. En particulier, chaque branche 9 peut comprendre une forme profilée de section carrée ou rectangulaire, la face supérieure 9s et la face inférieure 9i formant alors deux faces opposées parallèles. Avantageusement, les feuilles 10 reliées à une même branche sont reliées par alternance soit à la face supérieure 9s, soit à la face inférieure 9i de ladite branche. Autrement dit, deux feuilles 10 voisines d'une même branche sont reliées respectivement à une face supérieure 9s et à une face inférieure 9i de cette branche. Sur la figure 2, les feuilles reliées à la face inférieure 9i d'une branche sont identifiées par la référence 10i, et les feuilles reliées à la face supérieure 9s de cette branche sont identifiées par la référence 10s. Une telle répartition facilite encore davantage le pivotement de chaque feuille relativement à la branche en évitant toute collision entre les feuilles adjacentes. La configuration rétractée du parasol est ainsi encore plus compacte.Each branch 9 includes an upper face 9s (visible for example on the figure 3 ) and a lower face 9i (visible for example on the figure 2 ) opposite the upper face 9s. In particular, each branch 9 may comprise a profiled shape of square or rectangular section, the upper face 9s and the lower face 9i then forming two parallel opposite faces. Advantageously, the sheets 10 connected to the same branch are connected alternately either to the upper face 9s or to the lower face 9i of said branch. In other words, two neighboring sheets 10 of the same branch are connected respectively to an upper face 9s and to a lower face 9i of this branch. On the figure 2 , the leaves connected to the lower face 9i of a branch are identified by the reference 10i, and the leaves connected to the upper face 9s of this branch are identified by the reference 10s. Such a distribution further facilitates further the pivoting of each leaf relative to the branch, avoiding any collision between adjacent leaves. The retracted configuration of the parasol is thus even more compact.

On comprend ainsi que les feuilles 10 formant un même écran peuvent être légèrement décalées les unes par rapport aux autres et que ce décalage est sensiblement égal à l'épaisseur des branches entre leur surface inférieure 9i et leur surface supérieure 9s.It is thus understood that the sheets 10 forming the same screen can be slightly offset from each other and that this offset is substantially equal to the thickness of the branches between their lower surface 9i and their upper surface 9s.

Les feuilles 10 reliées à une même branche comprennent une longueur L1 entre leur première extrémité 10A et leur deuxième extrémité 10B qui est croissante en fonction de leur éloignement à la première extrémité 9A de la branche 9 à laquelle elles sont liées. Chaque branche 9A pourvue de ses feuilles couvre ainsi un secteur de disque. L'angle A2 définissant ce secteur de disque peut être sensiblement égal à 360° divisé par le nombre de branches d'un même écran. Ainsi, les feuilles comblent efficacement l'espace entre deux branches adjacentes en laissant des ouvertures 11 de relativement faibles dimensions. Dans l'hypothèse où le parasol comprend plusieurs écrans superposés, comme cela sera décrit par la suite, l'angle A2 d'un secteur de disque peut être inférieur à 360° divisé par le nombre de branches. Dans ce cas, l'espace formé entre deux branches adjacentes d'un même écran peut être comblé par une branche d'un écran inférieur ou supérieur. Globalement, les feuilles 10 présentent une longueur L1 plus importante qu'une feuille d'arbre naturelle.The leaves 10 connected to the same branch comprise a length L1 between their first end 10A and their second end 10B which increases as a function of their distance from the first end 9A of the branch 9 to which they are connected. Each branch 9A provided with its leaves thus covers a disk sector. The angle A2 defining this disk sector can be substantially equal to 360° divided by the number of branches of the same screen. Thus, the leaves effectively fill the space between two adjacent branches by leaving openings 11 of relatively small dimensions. In the event that the parasol comprises several superimposed screens, as will be described later, the angle A2 of a disk sector can be less than 360° divided by the number of branches. In this case, the space formed between two adjacent branches of the same screen can be filled by a branch of a lower or higher screen. Overall, the leaves 10 have a length L1 greater than a natural tree leaf.

Avantageusement, le parasol comprend en outre un moyen de synchronisation configuré de sorte qu'un pivotement d'une branche 9 autour de son deuxième axe de rotation R2 entraîne automatiquement un pivotement des feuilles 10 reliées à cette branche autour de leur axe de rotation R1 respectif. Le moyen de synchronisation permet ainsi de replier automatiquement les feuilles lorsque le parasol passe de sa configuration déployée à sa configuration rétractée. Pour faire passer le parasol de la configuration déployée à la configuration rétractée, il suffit donc d'agir sur les branches du parasol. Grâce au moyen de synchronisation, les feuilles 10 se déploient ou se rétractent automatiquement en manipulant les branches 9. Le moyen de synchronisation permet également de s'assurer que les feuilles restent bloquées en position lorsque le parasol est stable en configuration déployée ou en configuration rétractée.Advantageously, the parasol further comprises a synchronization means configured so that a pivoting of a branch 9 about its second axis of rotation R2 automatically causes a pivoting of the leaves 10 connected to this branch about their respective axis of rotation R1. The synchronization means thus makes it possible to automatically fold the leaves when the parasol passes from its configuration deployed to its retracted configuration. To switch the parasol from the deployed configuration to the retracted configuration, it is therefore sufficient to act on the branches of the parasol. Thanks to the synchronization means, the leaves 10 deploy or retract automatically by manipulating the branches 9. The synchronization means also makes it possible to ensure that the leaves remain locked in position when the parasol is stable in the deployed configuration or in the retracted configuration.

Les figures 4 et 5 illustrent plus en détail un mode de réalisation du moyen de synchronisation. Chaque branche 9 est équipée d'un axe 14 s'étendant parallèlement à la branche, c'est-à-dire parallèlement à l'axe X2. L'axe 14 est également monté coulissant relativement à la branche 9 selon l'axe X2. A chaque feuille 10 est associée une bielle 15. Chaque bielle 15 est montée pivotante par rapport à la branche 9 autour d'un point de pivot 16. Chaque bielle 15 est également fixée à la fois à l'axe 14 et à une feuille 10, respectivement en deux points de fixation 17 et 18. Le coulissement de l'axe 14 relativement à la branche 9 provoque la rotation de la bielle 15 autour de son point de pivot 16, et par conséquent un déplacement du point de fixation 18. L'effort appliqué par la bielle 15 fait ainsi tourner la feuille autour de son axe de rotation R1. Le mouvement de l'axe 14 relativement à la branche 9 peut être commandé par tout moyen, notamment par l'intermédiaire d'engrenages et/ou de câbles. Avantageusement, l'axe 14 est relié au pied 2 de sorte qu'un pivotement de la branche autour de son axe de rotation R2 induise automatiquement le coulissement de l'axe 14 relativement à la branche 9.THE figures 4 And 5 illustrate in more detail an embodiment of the synchronization means. Each branch 9 is equipped with an axis 14 extending parallel to the branch, i.e. parallel to the axis X2. The axis 14 is also mounted to slide relative to the branch 9 along the axis X2. Each sheet 10 is associated with a connecting rod 15. Each connecting rod 15 is mounted to pivot relative to the branch 9 about a pivot point 16. Each connecting rod 15 is also fixed both to the axis 14 and to a sheet 10, respectively at two fixing points 17 and 18. The sliding of the axis 14 relative to the branch 9 causes the connecting rod 15 to rotate about its pivot point 16, and consequently a displacement of the fixing point 18. The force applied by the connecting rod 15 thus causes the sheet to rotate about its axis of rotation R1. The movement of the axis 14 relative to the branch 9 can be controlled by any means, in particular by means of gears and/or cables. Advantageously, the axis 14 is connected to the foot 2 so that a pivoting of the branch about its axis of rotation R2 automatically induces the sliding of the axis 14 relative to the branch 9.

Selon le mode de réalisation présenté, le moyen de synchronisation est configuré de sorte que les feuilles 10 pivotent automatiquement vers le haut quand les branches 9 pivotent vers le haut, et elles pivotent automatiquement vers le bas quand les branches pivotent vers le bas. Selon une variante de réalisation les feuilles pourraient pivoter automatiquement vers le bas quand les branches pivotent vers le haut, et elles pourraient pivoter automatiquement vers le haut quand les branches pivotent vers le bas. Ceci permettrait de minimiser la variation de hauteur du centre de gravité de la partie protectrice 3 lorsque le parasol passe de sa configuration déployée à sa configuration rétractée. Ainsi, l'effort nécessaire pour réaliser cette transition serait réduit.According to the embodiment presented, the synchronization means is configured so that the leaves 10 automatically pivot upwards when the branches 9 pivot upwards, and they automatically pivot downwards when the branches pivot downwards. According to an alternative embodiment, the leaves could pivot automatically downward when the branches pivot upward, and they could automatically pivot upward when the branches pivot downward. This would minimize the height variation of the center of gravity of the protective part 3 when the umbrella transitions from its extended configuration to its retracted configuration. Thus, the effort required to make this transition would be reduced.

Selon un mode de réalisation simplifié, le parasol 1 pourrait ne pas comprendre de moyen de synchronisation. La rotation des feuilles 10 autour de leur axe de rotation R1 respectif pourrait être réalisée manuellement et/ou sous l'effet de la gravité. Lorsque le parasol est en configuration déployée, chaque feuille s'étend horizontalement ou quasi horizontalement, l'orientation d'une feuille ne subit donc pas ou très légèrement l'effet de gravité. En revanche, lorsque le parasol est en configuration rétractée, les feuilles peuvent s'orienter naturellement verticalement, sous l'effet de la force de gravité. Selon encore une variante de réalisation, on peut équiper chaque feuille avec un moyen de rappel, comme par exemple un ressort de torsion, pour favoriser une orientation donnée à chaque feuille.According to a simplified embodiment, the parasol 1 could not include a synchronization means. The rotation of the leaves 10 around their respective axis of rotation R1 could be carried out manually and/or under the effect of gravity. When the parasol is in the deployed configuration, each leaf extends horizontally or almost horizontally, the orientation of a leaf is therefore not subject to the effect of gravity or very slightly. On the other hand, when the parasol is in the retracted configuration, the leaves can naturally orient themselves vertically, under the effect of the force of gravity. According to yet another variant embodiment, each leaf can be equipped with a return means, such as for example a torsion spring, to promote a given orientation for each leaf.

Toutes les feuilles 10 du parasol ne sont pas nécessairement liées à une branche 9 par un moyen de liaison pivot 13. En particulier, le parasol 1 peut avantageusement comprendre un ensemble de feuilles statiques 19, chaque feuille statique 19 étant fixée rigidement à une extrémité libre 9B d'une branche 9. Quelle que soit la configuration du parasol, chaque feuille statique 19 s'étend dans le prolongement de l'axe dans lequel ladite branche s'étend. Les feuilles statiques 19 permettent d'agrandir l'ombre 8 produite par la partie protectrice 3 sans allonger les branches. Le parasol peut être ainsi encore plus léger relativement à la taille de l'ombre qu'il produit.Not all the leaves 10 of the parasol are necessarily connected to a branch 9 by a pivot connection means 13. In particular, the parasol 1 can advantageously comprise a set of static leaves 19, each static leaf 19 being rigidly fixed to a free end 9B of a branch 9. Whatever the configuration of the parasol, each static leaf 19 extends in the extension of the axis in which said branch extends. The static leaves 19 make it possible to enlarge the shadow 8 produced by the protective part 3 without lengthening the branches. The parasol can thus be even lighter relative to the size of the shadow that it produces.

La figure 5 illustre plus en détail le parasol 1. On observe que le parasol 1 comprend :

  • un premier ensemble de branches 91, chaque branche du premier ensemble de branches étant liée au pied 2,
  • un premier ensemble de feuilles 101, chaque feuille du premier ensemble de feuilles étant liée à une branche 91 du premier ensemble de branches par un moyen de liaison pivot 13 autour d'un axe de rotation R1,
  • un deuxième ensemble de branches 92, chaque branche du deuxième ensemble de branches étant liée au pied 2, et
  • un deuxième ensemble de feuilles 102, chaque feuille du deuxième ensemble de feuilles étant liée à une branche 92 du deuxième ensemble de branches par un moyen de liaison pivot 13 autour d'un axe de rotation R1.
There figure 5 illustrates in more detail the parasol 1. We observe that the parasol 1 comprises:
  • a first set of branches 91, each branch of the first set of branches being linked to foot 2,
  • a first set of leaves 101, each leaf of the first set of leaves being linked to a branch 91 of the first set of branches by a pivot linking means 13 about an axis of rotation R1,
  • a second set of branches 92, each branch of the second set of branches being linked to foot 2, and
  • a second set of leaves 102, each leaf of the second set of leaves being linked to a branch 92 of the second set of branches by a pivot linking means 13 about an axis of rotation R1.

Le premier ensemble de feuilles 101 forme un premier écran ajouré et le deuxième ensemble de feuilles 102 forme un deuxième écran ajouré lorsque le parasol est en configuration déployée. Le deuxième écran s'étend en dessous du premier écran. Le parasol comprend ainsi au moins deux écrans superposés ce qui améliore la protection conférée par le parasol. Avantageusement, les feuilles 102 du deuxième écran peuvent être agencées sensiblement en dessous des espaces formées entre les feuilles 101 du premier écran. Les branches 92 du deuxième ensemble de branches peuvent s'étendre en dessous d'un espace formé entre deux branches 91 adjacentes du premier ensemble de branches.The first set of leaves 101 forms a first openwork screen and the second set of leaves 102 forms a second openwork screen when the parasol is in the deployed configuration. The second screen extends below the first screen. The parasol thus comprises at least two superimposed screens which improves the protection provided by the parasol. Advantageously, the leaves 102 of the second screen can be arranged substantially below the spaces formed between the leaves 101 of the first screen. The branches 92 of the second set of branches can extend below a space formed between two adjacent branches 91 of the first set of branches.

Chacun des deux écrans peut comprendre une forme conique ou tronconique. L'angle de la forme conique ou tronconique de l'écran supérieur peut être strictement inférieur à l'angle de la forme conique ou tronconique de l'écran inférieur. Le pied 2 peut comprendre une barre verticale 20 reliant le centre du premier écran au centre du deuxième écran. Les branches 91 s'étendent radialement sensiblement depuis une extrémité supérieure de la barre verticale 20. Les branches 92 s'étendent radialement sensiblement depuis une extrémité inférieure de la barre verticale 20.Each of the two screens may comprise a conical or truncated shape. The angle of the conical or truncated shape of the upper screen may be strictly less than the angle of the conical or truncated shape of the lower screen. The foot 2 may comprise a vertical bar 20 connecting the center of the first screen to the center of the second screen. The branches 91 extend radially substantially from an upper end of the vertical bar 20. The branches 92 extend radially substantially from a lower end of the vertical bar 20.

Selon le mode de réalisation présenté le premier ensemble de branches 91 et le deuxième ensemble de branches 92 comprennent chacun six branches. Le parasol comprend donc en tout douze branches. En variante le nombre de branches pourrait être différent. Par exemple chaque écran du parasol peut être formé par un nombre de branches compris entre quatre et huit. De même, selon le mode de réalisation présenté, chaque branche porte huit feuilles dont quatre feuilles saillantes latéralement d'un premier côté de la branche, trois feuilles saillantes de l'autre côté de la branche, et une feuille statique. En variante, le nombre de feuilles portées par chaque branche pourrait être différent, par exemple compris entre cinq feuilles et quinze feuilles.According to the embodiment presented, the first set of branches 91 and the second set of branches 92 each comprise six branches. The parasol therefore comprises a total of twelve branches. Alternatively, the number of branches could be different. For example, each screen of the parasol can be formed by a number of branches of between four and eight. Similarly, according to the embodiment presented, each branch carries eight leaves, including four leaves projecting laterally on a first side of the branch, three leaves projecting on the other side of the branch, and one static leaf. Alternatively, the number of leaves carried by each branch could be different, for example between five leaves and fifteen leaves.

Finalement, grâce à l'invention on dispose d'un parasol produisant une ombre et une ventilation semblables à celles produites par un arbre. Le parasol est ainsi très agréable à utiliser. Le parasol est inspiré de la nature mais prévoit de plus des moyens de liaison pivot entre les feuilles et les branches du parasol ce qui produit de nombreux avantages, notamment la possibilité d'obtenir un parasol peu encombrant et avec une faible prise au vent lorsqu'il est en configuration rétractée.Finally, thanks to the invention, we have a parasol producing shade and ventilation similar to those produced by a tree. The parasol is therefore very pleasant to use. The parasol is inspired by nature but also provides pivot connection means between the leaves and the branches of the parasol, which produces many advantages, in particular the possibility of obtaining a parasol that is not bulky and with little wind resistance when it is in the retracted configuration.
