Description

DESCRIPTION DESCRIPTION
TITRE : Parasol comportant une structure souple TITLE: Parasol with a flexible structure
Domaine technique de l’invention Technical field of the invention
La présente invention concerne le domaine des parasols. The present invention relates to the field of umbrellas.
L’invention concerne plus particulièrement un parasol prévu pour se déployer depuis une position de rangement compacte. The invention relates more particularly to a parasol designed to be deployed from a compact storage position.
Arrière-plan technique Technical background
On connaît déjà des parasols déployables équipés de baleines comme sur un parapluie et d’un mécanisme qui permet le déploiement des baleines pour tendre une toile en tissus, par rapport à un mât rigide. We already know deployable parasols equipped with ribs as on an umbrella and with a mechanism which allows the deployment of the ribs to stretch a fabric canvas, compared to a rigid mast.
Ce type de parasol est relativement complexe à assembler et est particulièrement fragile en cas de vents forts. En effet, lorsque le vent est fort, il s’engouffre dans la toile ce qui exerce des efforts très importants sur les baleines qui finissent par plier ou casser. This type of parasol is relatively complex to assemble and is particularly fragile in the event of strong winds. Indeed, when the wind is strong, it rushes into the canvas which exerts very significant forces on the whales which end up bending or breaking.
Il a déjà été proposé des parasols utilisant un arceau fermé circulaire qui permet de tendre une voile en la fixant sur un mât. Toutefois, les solutions existantes restent fragiles et ne résistent pas bien en cas de vents forts. It has already been proposed parasols using a circular closed hoop which allows a sail to be stretched by fixing it on a mast. However, the existing solutions remain fragile and do not resist well in the event of strong winds.

L’invention vise à résoudre notamment les problèmes mentionnés précédemment en proposant un parasol comportant un élément de pied qui s’étend suivant une direction axiale principale et une structure de protection contre le soleil et/ou la pluie qui est montée de manière amovible sur l’élément de pied entre une position déployée et une position de rangement, la structure de protection comportant au moins une voile supérieure attachée à une partie haute de l’élément de pied et qui est prévue pour être tendue lorsque la structure de protection occupe sa position déployée, caractérisé en ce que : The invention aims to solve in particular the problems mentioned above by proposing a parasol comprising a foot element which extends in a main axial direction and a structure for protection against the sun and / or rain which is removably mounted on the foot element between a deployed position and a storage position, the protective structure comprising at least one upper sail attached to an upper part of the foot element and which is intended to be stretched when the protective structure occupies its position deployed, characterized in that:
- la structure de protection comporte au moins un premier arceau flexible et au moins un deuxième arceau flexible globalement circulaire sur l’un au moins desquels est montée ladite voile supérieure qui est prévue pour être tendue entre l’un au moins de ces arceaux et l’élément de pied lorsque la structure de protection occupe sa position déployée ; - the protective structure comprises at least one first flexible arch and at least one second generally circular flexible arch on at least one of which is mounted said upper sail which is intended to be stretched between at least one of these arches and the 'foot element when the protection structure occupies its deployed position;
- et en ce que la structure de protection comporte une partie inférieure de tension de la voile supérieure qui est reliée à l’élément de pied à une hauteur inférieure aux arceaux. - and in that the protective structure comprises a lower part for tensioning the upper sail which is connected to the foot element at a height lower than the arches.
L’invention propose de recourir à au moins deux arceaux flexibles associés pour assurer la mise en tension de la voile et la résistance au vent en position déployée, tout en étant chacun suffisamment flexible pour permettre de replier la structure de protection de sa position déployée jusqu’à sa position de rangement. The invention proposes to use at least two associated flexible arches to ensure the tensioning of the sail and the resistance to the wind in the deployed position, while each being sufficiently flexible to allow the protective structure to be folded from its deployed position to to its storage position.
La conception selon l’invention faisant appel à au moins deux arceaux flexibles de mise en tension permet de nombreuses combinaisons d’agencements relatifs des différents arceaux. Elle permet aussi différentes combinaisons de diamètres des différents arceaux et de la flexibilité de chaque arceau, par exemple en adoptant des aires en section différentes pour chaque arceau. The design according to the invention using at least two flexible tensioning hoops allows numerous combinations of relative arrangements of the different hoops. It also allows different combinations of diameters of the different arches and the flexibility of each arch, for example by adopting different cross-sectional areas for each arch.
Grâce à l’invention, le parasol est beaucoup plus résistant au vent, offre une grande portée d’ombre, tout en restant facile à replier dans la position de rangement. De plus, la fabrication et l’assemblage du parasol selon l’invention sont simples et économiques. Thanks to the invention, the parasol is much more resistant to the wind, offers a large shade range, while remaining easy to fold into the storage position. In addition, the manufacture and assembly of the umbrella according to the invention are simple and economical.
L’invention permet avantageusement de proposer un parasol disposant d’une aire d’ombre portée la plus grande possible. The invention advantageously makes it possible to propose a parasol having the largest possible shadow area.
Sans sortir du cadre de l’invention, une première partie de la structure de protection constituant ladite au moins une voile peut être une partie inférieure, tandis que l’autre partie de la structure de protection est alors une partie supérieure de tension. Without departing from the scope of the invention, a first part of the protective structure constituting said at least one sail can be a lower part, while the other part of the protective structure is then an upper tension part.

Description détaillée de l'invention Detailed description of the invention
Pour la description de l'invention et la compréhension des revendications, on utilisera à titre non limitatif et sans référence limitative à la gravité terrestre une orientation verticale suivant un axe principal A1 qui correspond à la direction du mât, ou élément de pied, du parasol représenté sur les figures. Des éléments seront qualifiés par les termes axial, transversal, radial en référence à cet axe principal. Selon une direction radiale, des éléments seront qualifiés d’intérieur ou d’extérieur selon qu’ils sont plus proches ou plus éloignés de l’axe principal. Dans la description qui va suivre, des éléments identiques, similaires ou analogues seront désignés par les mêmes chiffres de référence. For the description of the invention and the understanding of the claims, a vertical orientation along a main axis A1 which corresponds to the direction of the mast, or foot element, of the parasol will be used on a non-limiting basis and without limiting reference to the earth's gravity represented in the figures. Elements will be qualified by the terms axial, transverse, radial with reference to this main axis. In a radial direction, elements will be qualified as interior or exterior depending on whether they are closer or further from the main axis. In the following description, identical, similar or analogous elements will be designated by the same reference numerals.
Sur les figures 1 et 3, on a représenté un parasol 10 selon un premier mode de réalisation de l’invention. Le parasol 10 comporte un élément de pied 12, ou mât, qui s’étend suivant l’axe principal A1 , ici vertical, et une structure de protection 14 qui est montée de manière amovible ou démontable sur l’élément de pied 12. In Figures 1 and 3, there is shown a parasol 10 according to a first embodiment of the invention. The parasol 10 comprises a foot element 12, or mast, which extends along the main axis A1, here vertical, and a protective structure 14 which is removably or dismountably mounted on the foot element 12.
L’élément de pied 12 peut être réalisé en une seule pièce mais il est de préférence réalisé en plusieurs tronçons assemblés entre eux de manière à pouvoir occuper une position de rangement peu encombrante. The foot element 12 can be made in one piece but it is preferably made in several sections assembled together so as to be able to occupy a space-saving storage position.
L’élément de pied 12 comporte une extrémité axiale supérieure 16, sur laquelle une partie de la structure de protection 14 vient se positionner, et une extrémité axiale inférieure 18, qui est par exemple prévue pour être plantée dans le sol ou pour être fixée dans un socle de support (non représenté). The foot element 12 comprises an upper axial end 16, on which part of the protective structure 14 is positioned, and a lower axial end 18, which is for example intended to be planted in the ground or to be fixed in a support base (not shown).
La structure de protection 14 est prévue de préférence pour protéger les utilisateurs du soleil, mais elle pourrait aussi les protéger de la pluie. The protection structure 14 is preferably provided to protect the users from the sun, but it could also protect them from the rain.
La structure de protection 14 est représentée sur la figure 1 dans une position déployée et sur la figure 2 dans une position de rangement. The protective structure 14 is shown in Figure 1 in a deployed position and in Figure 2 in a storage position.
Selon ce premier mode de réalisation, la structure de protection 14 comporte une partie supérieure - ici en forme d’une voile supérieure 20 - et une partie inférieure - ici à titre non limitatif en forme d’une voile inférieure 22 associée à un dispositif de tension 38. According to this first embodiment, the protective structure 14 comprises an upper part - here in the form of an upper sail 20 - and a lower part - here without limitation in the form of a lower sail 22 associated with a device for tension 38.
Dans la position déployée, la voile supérieure 20 et la voile inférieure 22 sont montées tendues sur l’élément de pied 12 au moyen d’un premier arceau flexible 24 de mise en tension, d’un deuxième arceau flexible 26 de mise en tension, et au moyen du dispositif de tension 38 monté sur l’élément de pied 12 qui relie la voile inférieure 22 à l’élément de pied 12. In the deployed position, the upper sail 20 and the lower sail 22 are mounted taut on the foot element 12 by means of a first flexible hoop 24 for tensioning, a second flexible hoop 26 for tensioning, and by means of the tension device 38 mounted on the foot element 12 which connects the lower sail 22 to the foot element 12.
Avantageusement, chaque arceau 24, 26 a une forme circulaire fermée, et une section circulaire. Advantageously, each hoop 24, 26 has a closed circular shape, and a circular section.
Les arceaux 24, 26 sont ici concentriques. The arches 24, 26 are here concentric.
Chaque arceau 24, 26 est par exemple formé d’une tige en fibre de verre permettant d’obtenir une rigidité suffisante pour tendre les voiles 20, 22 et une flexibilité suffisante pour être repliée en 8 sans se briser. Ces arceaux 24, 26 sont aussi suffisamment épais pour résister ensemble au vent sans se briser. Each arch 24, 26 is for example formed of a fiberglass rod making it possible to obtain sufficient rigidity to stretch the sails 20, 22 and sufficient flexibility to be folded in a figure of 8 without breaking. These arches 24, 26 are also thick enough to withstand the wind together without breaking.
Chaque voile 20, 22 comporte sur son bord périphérique extérieur 28, 30 un fourreau 32, 34 prévu pour recevoir l’arceau 24, 26 associé et cousu à la voile 20, 22 associée. Each sail 20, 22 has on its outer peripheral edge 28, 30 a sheath 32, 34 provided to receive the associated hoop 24, 26 and sewn to the associated sail 20, 22.
Plus particulièrement, comme illustré par la figure 3, chaque fourreau 32, 34 est constitué ici par un rabat 35 cousu formé avec le même textile que celui constituant la voile 20, 22 et cousu sur la voile 20, 22 associée. Les deux fourreaux 32, 34 sont donc ici superposés axialement. More particularly, as illustrated by FIG. 3, each sheath 32, 34 is constituted here by a sewn flap 35 formed with the same textile as that constituting the sail 20, 22 and sewn onto the associated sail 20, 22. The two sheaths 32, 34 are therefore here superimposed axially.
Ainsi, le premier arceau 24 est ici emprisonné dans un fourreau supérieur 32 et le deuxième arceau 26 est ici emprisonné dans un fourreau inférieur 34. Avantageusement, les deux fourreaux 32, 34 sont cousus l’un avec l’autre selon une même ligne de couture 36 qui permet de les lier à la voile supérieure 20 et à la voile inférieure 22. Cette ligne de couture 36 unique prend en sandwich la voile supérieure 20, la voile inférieure 22, et les fourreaux 32, 34. Thus, the first hoop 24 is here imprisoned in an upper sheath 32 and the second hoop 26 is here imprisoned in a lower sheath 34. Advantageously, the two sheaths 32, 34 are sewn together along the same line of seam 36 which allows them to be linked to the upper sail 20 and the lower sail 22. This single line of stitching 36 sandwiches the upper sail 20, the lower sail 22, and the sleeves 32, 34.
De préférence, chaque fourreau 32, 34 présente une ouverture 37 qui facilite l’introduction de l’arceau 24, 26. Cependant, chaque fourreau 32, 34 peut également être totalement fermé lorsqu’une pièce de tissus additionnelle vient recouvrir cette ouverture 37 ou dans le cas où le fourreau est formé par deux disques cousus l’un sur l’autre. Preferably, each sheath 32, 34 has an opening 37 which facilitates the introduction of the arch 24, 26. However, each sheath 32, 34 can also be completely closed when an additional piece of fabric comes to cover this opening 37 or in the case where the sheath is formed by two discs sewn one on the other.
La voile supérieure 20 est ici attachée à l’extrémité axiale supérieure 16 de l’élément de pied 12, par exemple au moyen d’un œillet dans lequel l’extrémité axiale supérieure 16 est introduite, ou au moyen d’un renfort de tissus ou de tout autre élément adapté permettant de retenir le sommet de la voile supérieure 20 sur la partie haute de l’élément de pied 12. The upper sail 20 is here attached to the upper axial end 16 of the foot element 12, for example by means of an eyelet into which the upper axial end 16 is introduced, or by means of a fabric reinforcement or any other suitable element making it possible to retain the crown of the upper sail 20 on the upper part of the foot element 12.
La voile supérieure 20 se trouve ainsi tendue, grâce à l’élément de pied, entre l’extrémité axiale supérieure 16 de l’élément de pied 12 et les arceaux 24, 26. The upper sail 20 is thus stretched, thanks to the foot element, between the upper axial end 16 of the foot element 12 and the arches 24, 26.
La voile inférieure 22 est ici attachée à une partie du dispositif de tension 38 qui est lui-même fixé sur l’élément de pied 12 à une hauteur inférieure aux arceaux 24, 26. La voile inférieure 22 se trouve ainsi tendue entre le dispositif de tension 38 et les arceaux 24, 26. The lower sail 22 is here attached to a part of the tensioning device 38 which is itself fixed on the foot element 12 at a height lower than the hoops 24, 26. The lower sail 22 is thus stretched between the tensioning device 38 and the hoops 24, 26.
Le dispositif de tension 38 comporte par exemple un premier élément, tel qu’une rondelle, qui est fixé sur la voile inférieure et un second élément, tel qu’un bouton, qui est monté sur l’élément de pied 12 et qui peut être solidarisé au premier élément. The tensioning device 38 comprises for example a first element, such as a washer, which is fixed to the lower sail and a second element, such as a button, which is mounted on the foot element 12 and which can be attached to the first element.
Comme on peut le voir aux figures, le dispositif de tension 38 peut comporter une série de sangles ou bandes élastiques qui sont par exemple réparties angulairement de manière régulière autour de l’élément de pied. As can be seen in the figures, the tensioning device 38 may comprise a series of straps or elastic bands which are for example distributed angularly in a regular manner around the foot element.
Chaque sangle élastique s’étend entre la rondelle et le bord radialement intérieur de la voile inférieure 22. Each elastic strap extends between the washer and the radially inner edge of the lower sail 22.
Dans le cas où la partie inférieure ne comporte pas de voile proprement dite, les sangles élastiques s’étendent entre la rondelle et l’arceau concerné.In the case where the lower part does not include a sail as such, the elastic straps extend between the washer and the arch concerned.
La rondelle peut comporter une fente permettant de venir y bloquer le bouton, notamment sous la forme d’un bouton poussoir, et ainsi d’être fixée sur l’élément de pied ou mât 12. The washer may include a slot allowing the button to be blocked therein, in particular in the form of a push button, and thus to be fixed on the foot or mast element 12.
Ainsi, dans la position déployée de la figure 1 , les voiles supérieure 20 et inférieure 22 sont tendues de sorte que la voile supérieure 20 a globalement la forme d’un cône, ou tronc de cône, de diamètre décroissant vers le haut et la voile inférieure 22 a globalement la forme d’un cône ou tronc de cône de diamètre décroissant vers le bas. Thus, in the deployed position of Figure 1, the upper sails 20 and lower 22 are stretched so that the upper sail 20 has the overall shape of a cone, or truncated cone, of decreasing diameter upwards and the sail bottom 22 has the overall shape of a cone or truncated cone of decreasing diameter downwards.
De préférence, le dispositif de tension 38 est fixé à l’élément de pied 12 à une distance de la pointe de l’extrémité axiale supérieure 16 de l’élément de pied 12, au niveau de laquelle est positionné le haut de la voile supérieure 20, correspondant à au moins deux fois la longueur entre ladite pointe de l’élément de pied 12 et un plan horizontal formé par les arceaux 24, 26. Avantageusement, le rapport entre le diamètre déplié du parasol 10, ou de la structure de protection 14, et le diamètre de la section de chaque arceau 24, 26 est supérieur ou égal à 300, et de préférence inférieur à 500, de manière que les arceaux 24, 26 puissent être suffisamment flexibles pour occuper une position de rangement par torsion en 8, et suffisamment rigides pour résister à la force du vent dans la position déployée du parasol 10. Sur la figure 2 on a illustré schématiquement les différentes étapes mises en œuvre pour faire passer la structure de protection 14 de sa position déployée et démontée, illustrée par l’étape a, à sa position de rangement, illustrée par l’étape f. Preferably, the tension device 38 is attached to the leg member 12 at a distance from the tip of the upper axial end 16 of the leg member 12, at which the top of the upper sail is positioned. 20, corresponding to at least twice the length between said tip of the foot element 12 and a horizontal plane formed by the arches 24, 26. Advantageously, the ratio between the unfolded diameter of the parasol 10, or of the protective structure 14, and the diameter of the section of each hoop 24, 26 is greater than or equal to 300, and preferably less than 500, so that the hoop 24, 26 can be flexible enough to occupy a storage position by twisting in 8 , and sufficiently rigid to resist the force of the wind in the deployed position of the umbrella 10. In Figure 2 there is a schematic illustration of the different steps implemented to move the protective structure 14 from its deployed and disassembled position, illustrated by step a, to its storage position, illustrated by step f.
Au préalable, la structure de protection 14 est donc détachée de l’élément de pied 12, notamment en la décrochant du dispositif de tension 38 et en la retirant de l’extrémité axiale 16. La structure de protection 14 se trouve alors dans une configuration déployée et démontée, comme illustré par l’étape a sur la figure 2. Beforehand, the protective structure 14 is therefore detached from the foot element 12, in particular by unhooking it from the tensioning device 38 and by withdrawing it from the axial end 16. The protective structure 14 is then in a configuration deployed and disassembled, as shown in step a in Figure 2.
A partir de cette position déployée et démontée, une torsion est exercée par un utilisateur sur les deux arceaux 24, 26 afin de former un 8 comme illustré par l’étape b sur la figure 2. Chaque boucle du 8 vient ensuite se superposer l’une sur l’autre, comme illustré par l’étape c, jusqu’à obtenir un cercle de diamètre environ égal à la moitié du diamètre des arceaux 24, 26 en position déployée, comme illustré par l’étape d. From this deployed and dismantled position, a twist is exerted by a user on the two hoops 24, 26 in order to form an 8 as illustrated by step b in FIG. 2. Each loop of the 8 is then superimposed on the one on top of the other, as illustrated by step c, until a circle with a diameter approximately equal to half the diameter of the hoops 24, 26 in the deployed position, as illustrated by step d, is obtained.
A partir de la configuration illustrée par l’étape d, une nouvelle torsion est exercée sur les deux arceaux 24, 26 afin de former à nouveau un 8, comme illustré par l’étape e. Puis chaque boucle de ce nouveau 8 vient ensuite se superposer l’une sur l’autre, comme illustré par l’étape c, ce qui permet d’obtenir, dans la position de rangement, une structure en forme de disque de diamètre encore plus petit. From the configuration illustrated by step d, a new twist is exerted on the two arches 24, 26 in order to form a figure 8 again, as illustrated by step e. Then each loop of this new 8 is then superimposed on one another, as illustrated by step c, which makes it possible to obtain, in the storage position, a disc-shaped structure of even greater diameter. little.
C’est la flexibilité et l’élasticité des arceaux 24, 26 qui leur permet de passer de la position déployée à la position de rangement sans se briser. It is the flexibility and elasticity of the hoops 24, 26 which allows them to pass from the deployed position to the storage position without breaking.
Comme on peut le voir sur la figure 2, une sangle 40 peut être prévue pour maintenir la structure de protection 14 dans sa position de rangement en retenant les deux arceaux 24,26 dans la position de rangement. As can be seen in Figure 2, a strap 40 may be provided to maintain the protective structure 14 in its storage position by retaining the two arches 24,26 in the storage position.
Cette sangle 40 peut être également fixée sur la structure de protection 14. La sangle 40 est par exemple cousue sur le bord périphérique extérieur 28 de la voile supérieure 20 par une première extrémité et elle possède un système d’attache qui permet de fixer l’autre extrémité à la voile supérieure 20 ou à la voile inférieure 22. La longueur de la sangle 40 est prévue pour contraindre la structure de protection 14 dans sa position de rangement. Pour optimiser la quantité de tissu utilisé pour la fabrication des voiles 20, 22, la voile supérieure 20 et la voile inférieure 22 sont composées chacune de deux panneaux de tissu et chaque fourreau 32, 34 est composé d’un panneau de tissu. This strap 40 can also be fixed to the protective structure 14. The strap 40 is for example sewn onto the outer peripheral edge 28 of the upper sail 20 by a first end and it has a fastening system which makes it possible to fix the other end to the upper sail 20 or to the lower sail 22. The length of the strap 40 is provided to constrain the protective structure 14 in its storage position. To optimize the quantity of fabric used for the manufacture of the sails 20, 22, the upper sail 20 and the lower sail 22 are each made up of two panels of fabric and each sheath 32, 34 is made up of a panel of fabric.
Selon une variante de réalisation (non représentée), les arceaux 24, 26 ne sont pas agencés à la périphérie de chaque voile 20, 22 mais décalés vers l’intérieur de sorte qu’une pièce de tissus de la voile supérieure 20 et/ou inférieure 22 puisse former un tombé sur le pourtour du parasol 10. Ce tombé peut être utilisé pour former des zones de rangement telles que des pochettes de rangement, ou contribuer à l’aspect esthétique du parasol 10. On décrira maintenant d’autres modes de réalisation de l’invention en insistant sur les aspects techniques différents, par rapport au premier mode de réalisation. According to a variant embodiment (not shown), the hoops 24, 26 are not arranged at the periphery of each sail 20, 22 but offset inwards so that a piece of fabric of the upper sail 20 and/or bottom 22 can form a fall on the periphery of the umbrella 10. This fall can be used to form storage areas such as storage pockets, or contribute to the aesthetic appearance of the umbrella 10. We will now describe other modes of embodiment of the invention emphasizing the different technical aspects, compared to the first embodiment.
Sur les figures 4 à 6, on a représenté un deuxième mode de réalisation de l’invention qui se distingue du premier mode de réalisation par le fait que les deux arceaux 24, 26 se croisent. In Figures 4 to 6, there is shown a second embodiment of the invention which differs from the first embodiment in that the two arches 24, 26 intersect.
Plus particulièrement, comme illustré en particulier par la figure 6, chaque fourreau 32, 34 comporte deux sections ouvertes 42 diamétralement opposées et chaque section ouverte 42 du fourreau supérieur 32 est superposée avec la section ouverte 42 du fourreau inférieur 34. More particularly, as illustrated in particular by Figure 6, each sleeve 32, 34 comprises two diametrically opposed open sections 42 and each open section 42 of the upper sleeve 32 is superimposed with the open section 42 of the lower sleeve 34.
Chaque arceau 24, 26 comporte un premier tronçon 44 qui est inséré dans le fourreau supérieur 32 et un deuxième tronçon 46 qui est inséré dans le fourreau inférieur 34, ledit arceau 24 passant du fourreau supérieur 32 au fourreau inférieur 34 au niveau de chaque section ouverte 42. Each hoop 24, 26 comprises a first section 44 which is inserted into the upper sleeve 32 and a second section 46 which is inserted into the lower sleeve 34, said hoop 24 passing from the upper sleeve 32 to the lower sleeve 34 at the level of each open section 42.
Selon une variante de réalisation (non représentée), les arceaux 24, 26 peuvent ne se croiser que d’un côté. Ceci permet d’utiliser uniquement deux fourreaux au lieu de quatre. According to a variant embodiment (not shown), the hoops 24, 26 may only intersect on one side. This allows the use of only two sheaths instead of four.
Sur les figures 7 à 9, on a représenté un troisième mode de réalisation de l’invention qui se distingue du premier mode de réalisation par le fait que les deux arceaux 24, 26 sont agencés dans un fourreau unique 32. In Figures 7 to 9, there is shown a third embodiment of the invention which differs from the first embodiment in that the two arches 24, 26 are arranged in a single sleeve 32.
Avantageusement, les deux arceaux 24, 26 sont agencés dans une gaine 47, c’est-à-dire revêtu d’une couche de matériau de protection qui permet notamment d’éviter l’usure par frottement entre les deux arceaux 24, 26. L’avantage de la gaine 47 est qu’elle permet de maintenir les arceaux 24, 26 dans une position prédéfinie. D’autres agencements sont possibles, par exemple une gaine 47 distincte pour chaque arceau 24, 26. Advantageously, the two arches 24, 26 are arranged in a sheath 47, that is to say coated with a layer of protective material which makes it possible in particular to avoid wear by friction between the two arches 24, 26. The advantage of the sheath 47 is that it keeps the hoops 24, 26 in a predefined position. Other arrangements are possible, for example a separate sheath 47 for each hoop 24, 26.
Dans le troisième mode de réalisation, les deux arceaux 24, 26 peuvent être de diamètres différents pour être agencés radialement de manière concentrique, comme illustré par les figures 7 et 8, ou de mêmes diamètres pour être agencés de manière superposée, comme illustré par la figure 9. On entend ici par radialement concentrique le fait qu’ils soient côte à côte, ou sensiblement parallèles, mais plus ou moins décalés suivant un rayon passant par l’axe principal A1 . In the third embodiment, the two arches 24, 26 can be of different diameters to be arranged radially in a concentric manner, as illustrated by FIGS. 7 and 8, or of the same diameters to be arranged in a superimposed manner, as illustrated by the FIG. 9. Radially concentric here means the fact that they are side by side, or substantially parallel, but more or less offset along a radius passing through the main axis A1.
Sur les figures 10 et 11 , on a représenté un quatrième mode de réalisation de l’invention qui se distingue du premier mode de réalisation par le fait que les deux fourreaux 32, 34 sont agencés radialement de manière concentrique et reliés par au moins une ligne de couture 36 commune, entre les deux fourreaux 32, 34. On comprend ici que les deux arceaux 24, 26 sont de diamètres différents et concentriques. In Figures 10 and 11, there is shown a fourth embodiment of the invention which differs from the first embodiment in that the two sleeves 32, 34 are arranged radially concentrically and connected by at least one line common seam 36, between the two sheaths 32, 34. It is understood here that the two hoops 24, 26 are of different and concentric diameters.
On note que la voile supérieure 20 et la voile inférieure 22 peuvent être cousues avec les fourreaux 32, 34 sur la ligne de couture 36 sur un bord radialement intérieur de la paire de fourreaux 32, 34, de manière à bien tendre les voiles 20, 22. It is noted that the upper sail 20 and the lower sail 22 can be sewn with the sleeves 32, 34 on the seam line 36 on a radially inner edge of the pair of sleeves 32, 34, so as to properly stretch the sails 20, 22.
Ainsi, au moins une voile, qui est prévue pour être tendue entre l’un au moins de ces arceaux 24, 26 et l’élément de pied 12 lorsque la structure de protection occupe sa position déployée, est montée sur l’un des deux arceaux, l’autre des deux arceaux étant associé avec cet arceau de montage de la toile pour résister à la force du vent dans la position déployée du parasol 10. Thus, at least one sail, which is intended to be stretched between at least one of these arches 24, 26 and the foot element 12 when the protective structure occupies its deployed position, is mounted on one of the two hoops, the other of the two hoops being associated with this canvas mounting hoop to resist the force of the wind in the deployed position of the parasol 10.
Sur les figures 12 et 13, on a représenté un cinquième mode de réalisation de l’invention qui se distingue du premier mode de réalisation par le fait que le premier arceau 24 a un diamètre supérieur au diamètre du deuxième arceau 26 de manière que, en position déployée, le premier arceau 24 soit agencé au niveau du bord périphérique extérieur 28 de la voile supérieure 20 et que le deuxième arceau 26 soit intercalé entre l’extrémité axiale supérieure 16 et le bord périphérique extérieur 28 de la voile supérieure 20. Les deux arceaux 24, 26 se retrouvent ainsi décalés radialement le long de la voile supérieure 20. In FIGS. 12 and 13, a fifth embodiment of the invention has been shown which differs from the first embodiment in that the first hoop 24 has a diameter greater than the diameter of the second hoop 26 so that, in deployed position, the first hoop 24 is arranged at the outer peripheral edge 28 of the upper sail 20 and the second hoop 26 is inserted between the upper axial end 16 and the outer peripheral edge 28 of the upper sail 20. The two arches 24, 26 are thus offset radially along the upper sail 20.
Comme on peut le voir à la figure 13, une bande de tissu s’étend radialement entre les deux fourreaux 32 et 34. As can be seen in Figure 13, a strip of fabric extends radially between the two sleeves 32 and 34.
Selon un exemple préféré de mise en œuvre, les deux voiles 20 et 22 sont cousues au niveau du fourreau radialement intérieur 34 et de l’arceau 26, tandis qu’une bande de tissu s’étend radialement entre les deux fourreaux 32 et 34 qui logent chacun un arceau concentriques 24, 26 (Comme la bande représentée à la figure 13 du cinquième mode de réalisation). According to a preferred example of implementation, the two sails 20 and 22 are sewn at the level of the radially inner sheath 34 and the hoop 26, while a strip of fabric extends radially between the two sheaths 32 and 34 which each house a concentric arch 24, 26 (like the strip shown in Figure 13 of the fifth embodiment).
Ainsi, la structure de protection comporte alors : Thus, the protective structure then comprises:
- une voile supérieure 20 et une voile inférieure 22 ; - an upper sail 20 and a lower sail 22;
- un arceau radialement intérieur 26 et un arceau radialement extérieur 24, les deux arceaux 24, 26 étant de diamètres différents pour être agencés radialement de manière concentrique, décalés suivant un rayon passant par l’axe principal A1 ; - a radially inner arch 26 and a radially outer arch 24, the two arches 24, 26 being of different diameters to be arranged radially concentrically, offset along a radius passing through the main axis A1;
- une bande de tissu, qui peut ne pas appartenir à la toile supérieure 20, qui s’étend radialement entre les deux fourreaux radialement extérieur 32 (arceau 24) et radialement intérieur 34 (arceau 26). - a strip of fabric, which may not belong to the upper canvas 20, which extends radially between the two radially outer 32 (arch 24) and radially inner 34 (arch 26) sheaths.
Selon cet exemple de réalisation, les deux voiles 20 et 22 sont par exemple cousues ensemble au niveau du fourreau radialement intérieur 34 et de l’arceau 26, tandis que la bande de tissu s’étend radialement entre les deux fourreaux 32 et 34. According to this embodiment, the two webs 20 and 22 are for example sewn together at the level of the radially inner sheath 34 and of the hoop 26, while the strip of fabric extends radially between the two sheaths 32 and 34.
Le fourreau radialement extérieur 32 peut être constitué par un rabat rapporté sur la bande de tissu et le fourreau radialement intérieur 34 peut être constitué par un rabat rapporté sur la voile supérieure 20 à laquelle il est fixé par une couture qui est réalisée au niveau du raccordement de la périphérie de la voile inférieure 22 avec la voile supérieure 20, cette couture étant ainsi commune à la fixation du fourreau 34 et la fixation ensemble de la périphérie des deux voiles 20 et 22. The radially outer sleeve 32 may be formed by a flap attached to the strip of fabric and the radially inner sleeve 34 may be formed by a flap attached to the upper sail 20 to which it is fixed by a seam which is made at the level of the connection of the periphery of the lower sail 22 with the upper sail 20, this seam thus being common to the fixing of the sheath 34 and the fixing together of the periphery of the two sails 20 and 22.
Sur les figures 14 à 18, on a représenté un sixième mode de réalisation du parasol 10 selon l’invention qui se distingue du premier mode de réalisation par le fait que la structure de protection 14 comporte un troisième arceau 48. Les figures 15 à 18 illustrent plusieurs variantes possibles pour l’agencement des trois arceaux 24, 26, 48 entre eux. In Figures 14 to 18, there is shown a sixth embodiment of the umbrella 10 according to the invention which differs from the first embodiment in that the protective structure 14 comprises a third hoop 48. Figures 15 to 18 illustrate several possible variants for the arrangement of the three arches 24, 26, 48 between them.
Selon la variante des figures 15 et 16, les trois arceaux 24, 26, 48 sont agencés dans trois fourreaux 32, 34, 50 distincts, les deux premiers arceaux 24, 26 sont agencés comme dans le premier mode de réalisation alors que le troisième arceau 48 est décalé radialement vers l’extérieur et le troisième fourreau 50 est intercalé axialement entre le fourreau supérieur 32 et le fourreau inférieur 34. According to the variant of Figures 15 and 16, the three arches 24, 26, 48 are arranged in three separate sleeves 32, 34, 50, the first two arches 24, 26 are arranged as in the first embodiment while the third arch 48 is offset radially outwards and the third sleeve 50 is interposed axially between the upper sleeve 32 and the lower sleeve 34.
Selon la variante de la figure 17, les trois arceaux 24, 26, 48 et les trois fourreaux 32, 34, 50 sont superposés axialement. According to the variant of Figure 17, the three arches 24, 26, 48 and the three sleeves 32, 34, 50 are superposed axially.
Selon la variante de la figure 18, le premier arceau 24 et le deuxième arceau 26 sont concentriques radialement comme dans le quatrième mode de réalisation (figures 10 et 11) et le troisième arceau 48 est superposé axialement et intercalé radialement entre le premier arceau 24 et le deuxième arceau 26. According to the variant of FIG. 18, the first hoop 24 and the second hoop 26 are radially concentric as in the fourth embodiment (FIGS. 10 and 11) and the third hoop 48 is superposed axially and radially interposed between the first hoop 24 and the second hoop 26.
Sur les figures 19 à 21 , on a représenté un septième mode de réalisation du parasol 10 selon l’invention qui se distingue du premier mode de réalisation par le fait que la structure de protection 14 comporte un troisième arceau 48 agencé en spirale sur la voile supérieure 20 de manière que sa première extrémité 52 soit proche de l’extrémité axiale supérieure 16 de l’élément de pied 12 et que sa seconde extrémité 54 soit proche du bord périphérique extérieur supérieur 28. In Figures 19 to 21, there is shown a seventh embodiment of the umbrella 10 according to the invention which differs from the first embodiment in that the protective structure 14 comprises a third hoop 48 arranged in a spiral on the sail upper 20 so that its first end 52 is close to the upper axial end 16 of the foot element 12 and that its second end 54 is close to the upper outer peripheral edge 28.
Le troisième arceau 48 est ici inséré dans un troisième fourreau 50 qui décrit la même forme en spirale que le troisième arceau 48 et qui permet au troisième arceau 48 de décrire cette forme en spirale. Le troisième fourreau 50 est par exemple cousu dans le textile formant la voile supérieure 20. Selon une variante de réalisation (non représentée) du septième mode de réalisation, les deux arceaux périphériques 24, 26 peuvent être remplacés par un seul premier arceau 24 agencé dans un seul fourreau supérieur 32. Selon une variante de réalisation (non représentée) qui pourrait s’appliquer aux différents modes de réalisation décrits précédemment, l’élément de pied 12, et l’axe principal A1 , pourraient être décentrés, par rapport aux bords périphériques extérieurs 28, 30. La forme de la voile supérieure 20 et de la voile inférieure 22 devrait alors être adaptée. The third hoop 48 is here inserted into a third sheath 50 which describes the same spiral shape as the third hoop 48 and which allows the third hoop 48 to describe this spiral shape. The third sheath 50 is for example sewn into the textile forming the upper sail 20. According to a variant embodiment (not shown) of the seventh embodiment, the two peripheral arches 24, 26 can be replaced by a single first arch 24 arranged in a single upper sheath 32. According to a variant embodiment (not shown) which could apply to the various embodiments described above, the foot element 12, and the main axis A1, could be off-center, with respect to the edges outer peripherals 28, 30. The shape of the upper sail 20 and the lower sail 22 should then be adapted.
D’une manière générale, l’invention a été décrite et est définie aux revendications selon une conception dans laquelle la au moins une voile de protection est la voile supérieure et dans laquelle l’autre partie de la structure de protection assurant une fonction de mise sous tension est une partie inférieure. In general, the invention has been described and is defined in the claims according to a design in which the at least one protective sail is the upper sail and in which the other part of the protective structure ensuring a under tension is a lower part.
Sans sortir du cadre de l’invention, ladite au moins une voile peut être une voile inférieure, tandis que l’autre partie de la structure de protection est alors une partie supérieure de tension. Without departing from the scope of the invention, said at least one sail may be a lower sail, while the other part of the protective structure is then an upper tension part.
Selon une autre variante de réalisation (non représentée), le matériau textile constituant la voile supérieure 20 peut être différent du matériau constituant la voile inférieure 22. Par exemple, l’une des voiles 20, 22 pourrait être réalisée dans un matériau textile du type filet ajouré ou bien constituée seulement de sangles élastiques, ou bien comporter une partie de voile en matériau textile plein ou ajouré et une partie constituée de sangles telles que par exemple des sangles élastiques. According to another variant embodiment (not shown), the textile material constituting the upper sail 20 may be different from the material constituting the lower sail 22. For example, one of the sails 20, 22 could be made of a textile material of the type perforated net or alternatively consisting only of elastic straps, or alternatively comprising a part of the sail made of solid or perforated textile material and a part consisting of straps such as, for example, elastic straps.
