Description

Domaine techniqueTechnical area

La présente invention est relative aux parasols comportant un pied, destiné à être posé sur le sol, ainsi qu'une toile, positionnée au niveau d'une extrémité du pied, et configurée pour générer une surface ombragée sur le sol, à proximité du pied.The present invention relates to parasols comprising a foot, intended to be placed on the ground, as well as a canvas, positioned at one end of the foot, and configured to generate a shaded surface on the ground, near the foot. .

Technique antérieurePrior art

De façon connue, afin de faciliter leur transport, la toile de tels parasols peut être reçue sur ledit pied par l'intermédiaire de moyens de fixation, configurés pour permettre à ladite toile de s'escamoter et se déployer à la manière d'un éventail, par l'intermédiaire de moyens de fixation, recevant ladite toile, et la reliant au pied du parasol. Ainsi, la toile, en position escamotée peut présenter un volume faible, facilitant sa manutention, mais conserver une taille suffisante, en position déployée de sorte à générer une surface ombragée à proximité du pied du parasol, permettant de protéger un utilisateur du soleil.In a known manner, in order to facilitate their transport, the canvas of such parasols can be received on said foot by means of fixing means, configured to allow said canvas to retract and deploy in the manner of a fan. , by means of fixing means, receiving said canvas, and connecting it to the foot of the parasol. Thus, the canvas, in the retracted position can have a small volume, facilitating its handling, but retain a sufficient size, in the deployed position so as to generate a shaded surface near the foot of the parasol, making it possible to protect a user from the sun.

On connaît par exemple du document ES 2 356 531 un tel parasol. Comme visible par exemple sur les figures 3 et 6 de ce document, les moyens de fixation de la toile au pied du parasol comprennent :

  • un axe,
  • une pluralité de baleines présentant chacune une portion d'articulation et une portion de fixation de la toile, les baleines étant toutes articulées autour dudit axe, par l'intermédiaire de leur portion d'articulation, avec leur dite portion de fixation s'étendant selon une direction sensiblement radiale de l'axe.
We know for example from the document ES 2 356 531 such a parasol. As visible for example on figures 3 and 6 of this document, the means of fixing the canvas to the foot of the parasol include:
  • an axe,
  • a plurality of ribs each having an articulation portion and an attachment portion of the canvas, the ribs all being articulated around said axis, by means of their articulation portion, with their said attachment portion extending along a substantially radial direction of the axis.

Les baleines définissent deux baleines d'extrémité : une baleine d'extrémité supérieure et une baleine d'extrémité inférieure, ainsi qu'une pluralité de baleines intermédiaires, et positionnées, selon la direction axiale de l'axe, entre la baleine d'extrémité supérieure et la baleine d'extrémité inférieure.The ribs define two end ribs: an upper end rib and a lower end rib, as well as a plurality of intermediate ribs, and positioned, in the axial direction of the axis, between the end rib upper and lower end whale.

La portion de fixation de chaque baleine d'extrémité reçoit une portion d'extrémité de la toile et chaque baleine intermédiaire reçoit une portion intermédiaire de la toile, située entre les deux portions d'extrémité de la toile, de telle sorte que la toile puisse passer :

  • d'une position escamotée, dans laquelle les portions de réception de chacune des baleines sont superposées selon la direction axiale de l'axe, à
  • une position déployée, dans laquelle l'axe est positionné selon une direction sensiblement parallèle au pied, et plusieurs baleines sont pivotées autour de l'axe, tel que au moins deux baleines consécutives définissent entre-elles un angle non nul, et dans laquelle la toile est apte à permettre la formation d'une surface ombragée sur le sol, à proximité du pied, en entourant, au moins partiellement, le pied.
The attachment portion of each end rib receives an end portion of the web and each intermediate rib receives an intermediate portion of the web, located between the two end portions of the web, so that the web can pass :
  • a retracted position, in which the receiving portions of each of the ribs are superimposed in the axial direction of the axis, at
  • a deployed position, in which the axis is positioned in a direction substantially parallel to the foot, and several ribs are rotated around the axis, such that at least two consecutive ribs define between them a non-zero angle, and in which the canvas is suitable for allowing the formation of a shaded surface on the ground, near the foot, surrounding, at least partially, the foot.

Selon les constatations de l'inventeur, un tel parasol présente néanmoins l'inconvénient que le passage de la toile de la position escamotée à la position déployée nécessite un effort manuel d'un utilisateur, et que dans le cas d'une toile avec une surface importante, cet effort peut être important, ce qui est contraignant pour l'utilisateur.According to the findings of the inventor, such a parasol nevertheless has the drawback that the passage of the canvas from the retracted position to the deployed position requires a manual effort from a user, and that in the case of a canvas with a large surface area, this force can be significant, which is restrictive for the user.

Egalement, le passage de la toile de ladite position escamotée à ladite position déployée peut prendre un certain temps.Also, the passage of the canvas from said retracted position to said deployed position may take a certain time.

EP 3 187 663 A1 décrit aussi un parasol. EP 3 187 663 A1 also describes a parasol.

Problème techniqueTechnical problem

L'objectif de l'invention est donc de pallier aux inconvénients des parasols de l'art antérieur en proposant un parasol, dont le déploiement de la toile est facilité, et rapide.The objective of the invention is therefore to overcome the drawbacks of the parasols of the prior art by providing a parasol, the deployment of which of the fabric is facilitated, and rapid.

Un autre objectif de la présente invention est de proposer un tel parasol dont la toile peut passer de ladite position escamotée à ladite position déployée, très rapidement, de façon sensiblement instantanée.Another objective of the present invention is to provide such a parasol, the canvas of which can pass from said retracted position to said deployed position, very quickly, substantially instantaneously.

Un autre objectif de la présente invention est de proposer un tel parasol de conception simple, et de coût de revient réduit.Another objective of the present invention is to provide such a parasol with a simple design and low cost price.

Description des modes de réalisationDescription of the embodiments

Les dessins et la description ci-après contiennent, pour l'essentiel, des éléments de caractère certain. Ils pourront donc non seulement servir à mieux faire comprendre la présente invention, mais aussi contribuer à sa définition, le cas échéant.The drawings and the description below essentially contain elements of a certain nature. They can therefore not only serve to better understand the present invention, but also contribute to its definition, if necessary.

L'invention concerne un parasol 1 comprenant :

  • un pied 2, présentant deux extrémités 21, 22, et destiné à reposer sur le sol S au niveau d'une première extrémité 21,
  • une toile 3 comprenant deux portions d'extrémité 31, reliée au pied 2 par l'intermédiaire de moyens de fixation 4 disposés au niveau de la deuxième extrémité 22 du pied 2.
The invention relates to a parasol 1 comprising:
  • a foot 2, having two ends 21, 22, and intended to rest on the ground S at the level of a first end 21,
  • a canvas 3 comprising two end portions 31, connected to the foot 2 by means of fixing means 4 arranged at the level of the second end 22 of the foot 2.

Lesdits moyens de fixation 4 comprennent :

  • un axe 41,
  • une pluralité de baleines 42 présentant chacune une portion d'articulation 43 et une portion de fixation 44 de la toile, les baleines 42e, 42i étant toutes articulées autour dudit axe 41, par l'intermédiaire de leur portion d'articulation 43, avec leur dite portion de fixation 44 s'étendant selon une direction sensiblement radiale de l'axe 41.
Said fixing means 4 comprise:
  • an axis 41,
  • a plurality of ribs 42 each having an articulation portion 43 and an attachment portion 44 of the canvas, the ribs 42e, 42i all being articulated around said axis 41, by means of their articulation portion 43, with their said fixing portion 44 extending in a substantially radial direction of the axis 41.

Les baleines définissent deux baleines d'extrémité 42e: une baleine d'extrémité supérieure 42e et une baleine d'extrémité inférieure 42e, ainsi qu'une pluralité de baleines intermédiaires 42i, et positionnées, selon la direction axiale de l'axe 41, entre la baleine d'extrémité supérieure 42e et la baleine d'extrémité inférieure 42e.The ribs define two end ribs 42e: an upper end rib 42e and a lower end rib 42e, as well as a plurality of intermediate ribs 42i, and positioned, in the axial direction of the axis 41, between the upper end strut 42nd and the lower end strut 42nd.

La portion de fixation 44 de chaque baleine d'extrémité 42e reçoit une portion d'extrémité 31 de la toile 3 et chaque baleine intermédiaire 42i reçoit une portion intermédiaire 32 de la toile 3, située entre les deux portions d'extrémité 31 de la toile 3, de telle sorte que la toile 3 puisse passer :

  • d'une position escamotée, dans laquelle les portions de fixation 44 de chacune des baleines 42e, 42i sont superposées selon la direction axiale A41 de l'axe 41, à
  • une position déployée, dans laquelle plusieurs baleines 42e, 42i sont pivotées autour de l'axe 41, de telle sorte qu'au moins deux baleines 42e, 42i consécutives définissent entre-elles un angle A42 non nul, et dans laquelle la toile 3 est apte à permettre la formation d'une surface ombragée sur le sol S, à proximité du pied 2, la toile 3 entourant, au moins partiellement, le pied 2.
The fixing portion 44 of each end rib 42e receives an end portion 31 of the fabric 3 and each intermediate rib 42i receives an intermediate portion 32 of the fabric 3, located between the two end portions 31 of the fabric 3, so that the fabric 3 can pass:
  • a retracted position, in which the fixing portions 44 of each of the ribs 42e, 42i are superimposed in the axial direction A41 of the axis 41, to
  • a deployed position, in which several ribs 42e, 42i are pivoted about the axis 41, so that at least two consecutive ribs 42e, 42i define between them a non-zero angle A42, and in which the fabric 3 is capable of allowing the formation of a shaded surface on the ground S, near the foot 2, the canvas 3 surrounding, at least partially, the foot 2.

Selon l'invention, lesdits moyens de fixation 4 comprennent en outre un élément élastique 45 configuré de sorte à entraîner le pivotement de la baleine d'extrémité supérieure 42e par rapport à la baleine d'extrémité inférieure 42e, afin d'entraîner le passage de la position escamotée à la position déployée de la toile 3.According to the invention, said fixing means 4 further comprise an elastic element 45 configured so as to cause the pivoting of the end whale. 42nd upper relative to the lower end whale 42nd, in order to cause the passage from the retracted position to the deployed position of the canvas 3.

Ainsi, le passage de la position escamotée à la position déployée de la toile 3 se fait sous l'action du moyen élastique 45, sans nécessiter d'effort d'un utilisateur, qui pourrait générer chez lui de l'inconfort, et notamment dans le cas d'une toile avec un volume important.Thus, the passage from the retracted position to the deployed position of the canvas 3 takes place under the action of the elastic means 45, without requiring any effort from a user, which could generate discomfort in him, and in particular in the case of a canvas with a large volume.

L'emploi d'un tel moyen élastique 45 permet également un passage quasi-instantané de la position escamotée à la position déployée de la toile 3, et contrairement aux parasols de l'état de la technique.The use of such an elastic means 45 also allows an almost instantaneous passage from the retracted position to the deployed position of the canvas 3, and unlike the parasols of the state of the art.

Le pied 2 peut par exemple comporter un support (non-représenté), configuré de sorte à reposer en appui sur le sol S, avantageusement lorsque le parasol 1 doit être posé sur un sol S dur, comme par exemple du béton, ou alternativement pour être planté dans le sol S, avantageusement lorsque le parasol doit être posé sur un sol S mou, comme par exemple du sable.The foot 2 can for example include a support (not shown), configured so as to rest on the ground S, advantageously when the parasol 1 must be placed on a hard ground S, such as for example concrete, or alternatively to be planted in the ground S, advantageously when the parasol must be placed on a soft ground S, such as for example sand.

Comme visible plus particulièrement sur l'exemple de réalisation de la figure 6a, la portion d'articulation 43 d'une baleine 42e, 42i peut être constituée d'une pièce sensiblement plane, par exemple en matériau plastique, tandis que la portion de fixation 44 d'une baleine 42e, 42i peut être constituée par une tige, notamment sensiblement cylindrique, par exemple en matériau plastique également.As visible more particularly on the embodiment of the figure 6a , the articulation portion 43 of a whale 42e, 42i may consist of a substantially planar part, for example of plastic material, while the fixing portion 44 of a whale 42e, 42i may consist of a rod , in particular substantially cylindrical, for example also of plastic material.

Ladite portion de fixation 44 peut être amovible par rapport à la portion d'articulation 43, ou alternativement, elles peuvent être ménagées d'un seul tenant.Said fixing portion 44 may be removable with respect to the articulation portion 43, or alternatively, they may be provided in one piece.

Comme visible sur les exemples de réalisation des figures 3a, 3b et 6, les baleines intermédiaires 42i peuvent être toutes identiques, tandis que les baleines d'extrémité 42e peuvent également être identiques.As can be seen on the examples of the figures 3a, 3b and 6 , the intermediate ribs 42i can all be identical, while the end ribs 42e can also be identical.

Selon un mode de réalisation, l'élément élastique 45 consiste en un ressort de torsion 45 relié à la baleine d'extrémité inférieure 42e et à la baleine d'extrémité supérieure 42e, et configuré de sorte à appliquer un effort F45 s'étendant selon une direction sensiblement perpendiculaire à une direction radiale de l'axe 41, à ladite baleine d'extrémité supérieure 42e, et à ladite baleine d'extrémité inférieure 42e, l'effort F45 appliqué à la baleine d'extrémité inférieure 42e étant de sens opposé à l'effort F45 appliqué à la baleine d'extrémité supérieure 42e.According to one embodiment, the elastic element 45 consists of a torsion spring 45 connected to the lower end whale 42e and to the upper end whale 42e, and configured so as to apply a force F45 extending along a direction substantially perpendicular to a radial direction of the axis 41, to said upper end whale 42e, and to said lower end whale 42e, the force F45 applied to the lower end whale 42e being in the opposite direction to the force F45 applied to the upper end whale 42nd.

Comme visible sur l'exemple de réalisation de la figure 3, les baleines d'extrémité 42e sont ainsi sollicitées de sorte à pivoter autour de l'axe 41, selon chacune un sens opposé. Les portions d'extrémité 31 de la toile 3, reliées aux baleines d'extrémité 42e vont également être sollicitées de sorte à s'éloigner l'une de l'autre, tout comme les portions intermédiaires 32 de ladite toile 3, et à pivoter autour dudit axe 41, permettant à la toile 3 de se déplier autour dudit axe 41, afin de passer de la position escamotée à ladite position déployée.As can be seen on the example of the figure 3 , the end ribs 42e are thus biased so as to pivot about the axis 41, each in an opposite direction. The end portions 31 of the canvas 3, connected to the end ribs 42e will also be biased so as to move away from each other, just like the intermediate portions 32 of said canvas 3, and to pivot. around said axis 41, allowing the canvas 3 to unfold around said axis 41, in order to pass from the retracted position to said deployed position.

Selon un mode de réalisation, ledit ressort de torsion 45 comporte une partie tubulaire 45T, définissant une extrémité supérieure 45S et une extrémité inférieure 45I, avec une pluralité de spires recevant intérieurement ledit axe 41, et deux branches d'extrémité 45E positionnées chacune au niveau d'une extrémité 45I, 45S de la partie tubulaire 45T du ressort de torsion 45, en saillie depuis ladite partie tubulaire selon une direction sensiblement tangentielle de la partie tubulaire 45T.According to one embodiment, said torsion spring 45 comprises a tubular part 45T, defining an upper end 45S and a lower end 45I, with a plurality of turns internally receiving said axis 41, and two end branches 45E each positioned at the level of one end 45I, 45S of the tubular part 45T of the torsion spring 45, projecting from said tubular part in a direction substantially tangential to the tubular part 45T.

L'emploi d'un tel ressort de torsion 45 permet avantageusement de fournir un effort F45 suffisant au niveau des baleines d'extrémité 42e, par l'intermédiaire du bras de levier permis par les branches d'extrémité 45E du ressort de torsion 45, décuplant l'effort de torsion fourni par les spires de la partie tubulaire 45T du ressort de torsion 45.The use of such a torsion spring 45 advantageously makes it possible to provide a sufficient force F45 at the level of the end ribs 42e, by means of the lever arm allowed by the end branches 45E of the torsion spring 45, tenfold the torsional force provided by the turns of the tubular part 45T of the torsion spring 45.

Comme visible plus particulièrement sur l'exemple de réalisation de la figure 6b, les branches d'extrémité 45E du ressort de torsion 45 peuvent définir entre elles un angle correspondant à l'angle défini par toile 3 autour de l'axe 41 dans sa position déployée.As visible more particularly on the embodiment of the figure 6b , the end branches 45E of the torsion spring 45 can define between them an angle corresponding to the angle defined by fabric 3 around the axis 41 in its deployed position.

Selon un mode de réalisation, chaque branche d'extrémité 45E du ressort de torsion 45 est reçue dans une rainure R42 ménagée dans la portion d'articulation 43 de la baleine d'extrémité supérieure 42e, respectivement de la baleine d'extrémité inférieure 42e, ladite rainure R42 étant configurée de sorte à s'étendre selon une direction sensiblement radiale de l'axe 41.According to one embodiment, each end branch 45E of the torsion spring 45 is received in a groove R42 formed in the articulation portion 43 of the upper end whale 42e, respectively of the lower end whale 42e, said groove R42 being configured so as to extend in a substantially radial direction of axis 41.

Comme visible plus particulièrement sur l'exemple de réalisation de la figure 5, cette disposition avantageuse de l'invention permet de maximiser la surface de la portion d'articulation 43 de la baleine d'extrémité 42e sur laquelle la banche d'extrémité 45E du ressort de 45 exerce ledit effort F45 et donc de répartir cet effort sur toute la longueur de ladite rainure R42.As visible more particularly on the embodiment of the figure 5 , this advantageous arrangement of the invention makes it possible to maximize the surface of the articulation portion 43 of the end rib 42e on which the end plate 45E of the spring 45 exerts said force F45 and therefore to distribute this force over the entire length of said groove R42.

Afin de faciliter la mise en place de ladite branche d'extrémité 45E du ressort de torsion 45 dans ladite rainure R42, celle-ci peut être prévue débouchante sur une face F43 de la portion d'articulation 43 de la baleine d'extrémité 42e.In order to facilitate the positioning of said end branch 45E of the torsion spring 45 in said groove R42, the latter may be provided to open onto a face F43 of the articulation portion 43 of the end rib 42e.

Selon un mode de réalisation, chaque portion d'articulation 43 de chaque baleine 42e, 42i comporte, au niveau d'une extrémité 43E de ladite portion d'articulation 43, un perçage traversant 46, configuré pour recevoir ledit axe 41 et ladite partie tubulaire 45T du ressort de torsion 45, avec une paroi périphérique 47 comprenant une face intérieure 47I et une face extérieure 47E.According to one embodiment, each articulation portion 43 of each rib 42e, 42i comprises, at an end 43E of said articulation portion 43, a through bore 46, configured to receive said pin 41 and said tubular part. 45T of the torsion spring 45, with a peripheral wall 47 comprising an inner face 47I and an outer face 47E.

Selon un tel mode de réalisation, sur chaque baleine intermédiaire 42i, une fente de passage 48 est ménagée dans ladite paroi périphérique 47 du perçage traversant 46, s'étendant entre la face intérieure 47I et la face extérieure 47E et configurée de sorte à permettre le passage d'un branche d'extrémité 45E du ressort de torsion 45.According to such an embodiment, on each intermediate rib 42i, a passage slot 48 is formed in said peripheral wall 47 of the through hole 46, extending between the inner face 47I and the outer face 47E and configured so as to allow the passage of an end branch 45E of the torsion spring 45.

Comme visible sur les exemples de réalisation des différentes figures, les perçages traversant 46 de chacune des portions d'articulation 43 de chacune des baleines intermédiaires 42i sont ainsi empilées selon la direction axiale de l'axe 41.As can be seen in the exemplary embodiments of the various figures, the through holes 46 of each of the articulation portions 43 of each of the intermediate ribs 42i are thus stacked in the axial direction of the axis 41.

Egalement, comme visible su l'exemple de réalisation de la figure 5, les portions d'articulation 43 de chacune des baleines d'extrémité 42e reçoivent également un perçage traversant 46, configuré pour recevoir ledit axe 41, lesdits perçages traversant 46 des portions d'articulation 43 des baleines d'extrémité 42e étant également empilés avec les perçages traversant 46 des portions d'articulation 43 des baleines intermédiaires 42i, selon la direction axiale A41 de l'axe 41.Also, as can be seen from the example of the realization of the figure 5 , the articulation portions 43 of each of the end ribs 42e also receive a through bore 46, configured to receive said pin 41, said bores passing through 46 of the articulation portions 43 of the end ribs 42e also being stacked with the holes 46 passing through the articulation portions 43 of the intermediate ribs 42i, in the axial direction A41 of the axis 41.

Comme visible sur l'exemple de réalisation de la figure 5, la rainure R42 peut avantageusement être disposée selon une direction sensiblement tangentielle du perçage traversant 46 sur la portion d'articulation 43 de la baleine d'extrémité 42e, de sorte à recevoir la branche d'extrémité 45E du ressort de torsion 45, sans risquer de la déformer.As can be seen on the example of the figure 5 , the groove R42 can advantageously be arranged in a substantially tangential direction of the through hole 46 on the articulation portion 43 of the end rib 42e, so as to receive the end branch 45E of the torsion spring 45, without risking to deform it.

Selon les constatations de l'inventeur, en l'absence d'une telle fente de passage 48 au niveau du perçage traversant 46, la mise en place du ressort de torsion 45, de telle sorte que la partie tubulaire 45T dudit ressort de torsion 45 reçoive intérieurement l'axe 41, et que l'axe 41 soit également reçu dans la pluralité de logement 46, et que les branches d'extrémité 45E du ressort de torsion 45 viennent chacune se loger dans les rainures R42 de la portion d'articulation 43 de chacune des baleines d'extrémité 42e, s'avérerait particulièrement complexe à effectuer, et nécessiterait la déformation desdites branches d'extrémité 45E du ressort de torsion 45, ce qui peut les détériorer ou encore nuire à la précision de l'assemblage entre ces différents éléments et donc au fonctionnement du parasol 1 selon l'invention.According to the findings of the inventor, in the absence of such a passage slot 48 at the level of the through hole 46, the positioning of the torsion spring 45, such that the tubular portion 45T of said torsion spring 45 receives the axis 41 internally, and that the axis 41 is also received in the plurality of housing 46, and that the end branches 45E of the torsion spring 45 each come to be housed in the grooves R42 of the articulation portion 43 of each of the end ribs 42e, would prove to be particularly complex to perform, and would require the deformation of said branches end 45E of the torsion spring 45, which may damage them or even harm the precision of the assembly between these different elements and therefore the operation of the parasol 1 according to the invention.

La présence d'une telle fente de passage 48 dans la paroi périphérique 47 des perçages traversant 46 des portions d'articulation 43 des baleines intermédiaires 42i permet le passage d'au moins une branche d'extrémité 45E du ressort de torsion 45 lors de sa mise en place dans les baleines intermédiaires 42i, afin de pouvoir coulisser le long de la direction d'empilement des baleines intermédiaires 42i.The presence of such a passage slot 48 in the peripheral wall 47 of the bores passing through 46 of the articulation portions 43 of the intermediate ribs 42i allows the passage of at least one end branch 45E of the torsion spring 45 during its placement in the intermediate ribs 42i, in order to be able to slide along the stacking direction of the intermediate ribs 42i.

Comme visible notamment sur l'exemple de réalisation de la figure 6b, cette disposition avantageuse de l'invention facilite la mise en place du ressort de torsion 45 dans les baleines intermédiaires 42i, et évite de déformer les branches d'extrémité 45E du ressort de torsion 45 à cet effet, et donc de risquer de détériorer ce ressort de torsion 45.As visible in particular on the example of the realization of the figure 6b , this advantageous arrangement of the invention facilitates the positioning of the torsion spring 45 in the intermediate ribs 42i, and avoids deforming the end branches 45E of the torsion spring 45 for this purpose, and therefore running the risk of damaging this torsion spring 45.

Selon un mode de réalisation, les fentes de passage 48 de chaque baleine intermédiaire 42i sont configurées de sorte à se retrouver alignées sensiblement selon la direction axiale A41 de l'axe 41, lorsque les baleines intermédiaires 42i sont alignées selon ladite direction axiale A41 de l'axe 41.According to one embodiment, the passage slots 48 of each intermediate rib 42i are configured so as to be aligned substantially along the axial direction A41 of the axis 41, when the intermediate ribs 42i are aligned along said axial direction A41 of the 'axis 41.

Comme visible en partie sur les exemples de réalisation des figures 6a et 6b, grâce à cette disposition avantageuse de l'invention, la mise en place du ressort de torsion 45 dans les perçages traversant 46 des portions d'articulation 43 des baleines intermédiaires 42i, et notamment des portions d'articulation 43 des baleines 42 peut se faire selon la séquence suivante :

  1. (1) Les baleines intermédiaires 42i sont empilées de sorte à ce que leurs perçages traversant 46 se trouvent dans le prolongement l'un de l'autre, et de sorte que lesdites fentes de passage 48 de chacune desdites baleines intermédiaire 42i se retrouvent également dans le prolongement l'une de l'autre selon la direction d'empilement des baleines intermédiaires 42i,
  2. (2) Le ressort de torsion 45 est introduit et translaté à travers l'ensemble des perçages traversant 46, selon la direction d'empilement des baleines intermédiaires 42i, une branche d'extrémité 45E du ressort de torsion 45, coulissant selon ladite direction d'empilement des baleines intermédiaires 42i, successivement au travers des fentes de passage 48 des perçages traversant 46 de chacune des portions d'articulation, jusqu'à ce que le ressort de torsion 45 soit positionné avec sa partie tubulaire 45T au niveau des perçages traversant 46 des baleines intermédiaires 42i et des branches d'extrémité 45E à l'extérieur des perçages traversant 46 des baleines intermédiaires 42i.
As can be seen in part on the examples of figures 6a and 6b , thanks to this advantageous arrangement of the invention, the positioning of the torsion spring 45 in the bores passing through 46 of the articulation portions 43 of the intermediate ribs 42i, and in particular of the articulation portions 43 of the ribs 42 can be done according to the following sequence:
  1. (1) The intermediate ribs 42i are stacked so that their through holes 46 are in the extension of one another, and so that said passage slots 48 of each of said intermediate ribs 42i are also found in the extension of one another in the direction of stacking of the intermediate ribs 42i,
  2. (2) The torsion spring 45 is introduced and translated through the set of through holes 46, in the direction of stacking of the intermediate ribs 42i, an end branch 45E of the torsion spring 45, sliding in said direction d 'stacking of the intermediate ribs 42i, successively through the passage slots 48 of the through holes 46 of each of the articulation portions, until the torsion spring 45 is positioned with its tubular part 45T at the level of the through holes 46 intermediate ribs 42i and end branches 45E outside the holes 46 passing through the intermediate ribs 42i.

Alternativement, les portions d'articulation 43 des baleines intermédiaires 42i peuvent être empilées directement sur la partie tubulaire 45T du ressort de torsion 45, l'une des branches d'extrémité 45E du ressort de torsion 45 passant au travers de ladite fente de passage 48 du perçage traversant 46 lors de la mise en place de ladite portion d'articulation 43 de la baleine intermédiaire 42i sur le ressort d'articulation 45, avec le perçage traversant 46 autour de la partie tubulaire 45T du ressort de torsion 45.Alternatively, the articulation portions 43 of the intermediate ribs 42i can be stacked directly on the tubular part 45T of the torsion spring 45, one of the end branches 45E of the torsion spring 45 passing through said passage slot 48 of the through hole 46 when placing said articulation portion 43 of the intermediate rib 42i on the articulation spring 45, with the through hole 46 around the tubular portion 45T of the torsion spring 45.

Les branches d'extrémité 45E du ressort de torsion 45 peuvent être mise en place dans les rainures R42 de chacune des baleines d'extrémité 42e à différents moments de la séquence décrite ci-dessus.The end branches 45E of the torsion spring 45 can be placed in the grooves R42 of each of the end ribs 42e at different times in the sequence described above.

Par exemple, la branche d'extrémité 45E, située au niveau d'une des extrémités inférieure 45I ou supérieure 45S du ressort de torsion 45 peut être positionnée dans la rainure 42 de la baleine d'extrémité 42e inférieure, respectivement supérieure, préalablement à l'étape (2) de la séquence décrite ci-dessus, tandis que l'autre branche d'extrémité 45E, située au niveau de l'autre extrémité, inférieure 45I ou supérieure 45S, du ressort de torsion 45, est positionnée dans la rainure 42 de la baleine d'extrémité 42e supérieure, respectivement inférieure, à l'issue de l'étape (2) de la séquence décrite ci-dessus.For example, the end branch 45E, located at one of the lower ends 45I or upper 45S of the torsion spring 45 can be positioned in the groove 42 of the lower end whale 42e, respectively upper, prior to the step (2) of the sequence described above, while the other end branch 45E, located at the other end, lower 45I or upper 45S, of the torsion spring 45, is positioned in the groove 42 of the upper end whale 42nd, respectively lower, at the end of step (2) of the sequence described above.

Alternativement, chacune des branches d'extrémité 45E du ressort de torsion 45 est mis en place dans les rainures R42 de chacune des baleines d'extrémité 42e à l'issue de l'étape (2) de la séquence décrite ci-dessus.Alternatively, each of the end branches 45E of the torsion spring 45 is placed in the grooves R42 of each of the end ribs 42e at the end of step (2) of the sequence described above.

Egalement, l'axe 41 peut être positionné dans les perçages traversant 46 des portions d'articulation 43 des baleines intermédiaires 42i, préalablement ou à l'issue de l'étape (2) de la séquence décrite ci-dessus.Also, the pin 41 can be positioned in the bores passing through 46 of the articulation portions 43 of the intermediate ribs 42i, before or at the end of step (2) of the sequence described above.

Ainsi, l'assemblage des baleines 42e, 42i avec le ressort de torsion 45 et l'axe 41, selon les différentes séquences décrites ci-dessus s'avère particulièrement simple et rapide à mettre en œuvre, et ne risque pas de détériorer l'un quelconque de ces éléments, et donc de nuire au bon fonctionnement du parasol 1 selon l'invention.Thus, the assembly of the ribs 42e, 42i with the torsion spring 45 and the axis 41, according to the various sequences described above, proves to be particularly simple and quick to implement, and does not risk damaging the any of these elements, and therefore impair the proper functioning of the parasol 1 according to the invention.

Selon un mode de réalisation, chaque fente de passage 48 est une fente de passage 48 sensiblement rectiligne, s'étendant selon une direction tangentielle de la paroi périphérique 47 du perçage traversant 46.According to one embodiment, each passage slot 48 is a substantially rectilinear passage slot 48, extending in a direction tangential to the peripheral wall 47 of the through hole 46.

Cette disposition avantageuse de l'invention permet de positionner le ressort de torsion 45 lors de l'assemblage des baleines 42e, 42i avec le ressort de torsion 45 selon la séquence décrite ci-dessus, en s'assurant que le ressort de torsion 45, dont les branches d'extrémité 45E sont positionnées selon une direction sensiblement tangentielle de la partie tubulaire 45T du ressort de torsion 45, ne se déforment pas, lorsque ladite partie tubulaire 45T du ressort de torsion 45 est reçue dans ledit perçage traversant 46 et qu'une de ses branches d'extrémité 45E passe au travers de ladite fente de passage 48.This advantageous arrangement of the invention makes it possible to position the torsion spring 45 when assembling the ribs 42e, 42i with the torsion spring 45 according to the sequence described above, making sure that the torsion spring 45, whose end branches 45E are positioned in a direction substantially tangential to the tubular part 45T of the torsion spring 45, do not deform when said tubular part 45T of the torsion spring 45 is received in said through bore 46 and that ' one of its end branches 45E passes through said passage slot 48.

Selon un mode de réalisation, les moyens de fixation 4 sont solidaires d'un support 5 fixé sur le pied 2, par l'intermédiaire d'une articulation 6, configurée pour permettre le pivotement dudit support 5 par rapport au pied 2 selon au moins un axe de rotation A5, en particulier perpendiculaire au pied 2.According to one embodiment, the fixing means 4 are integral with a support 5 fixed to the foot 2, by means of an articulation 6, configured to allow the pivoting of said support 5 relative to the foot 2 according to at least an axis of rotation A5, in particular perpendicular to the foot 2.

Cette disposition avantageuse de l'invention permet de pouvoir positionner les baleines 42e, 42i, dans une position sensiblement parallèle au pied 2 du parasol, comme visible sur l'exemple de réalisation de la figure 7a, la toile 3 se trouvant avantageusement en position escamotée, afin de faciliter la manutention du parasol 1 selon l'invention, lorsque celui-ci n'est pas utilisé, à une position inclinée par rapport au pied 2, comme visible sur l'exemple de réalisation de la figure 7b, avant d'effectuer le passage de la toile 3 de sa position escamotée à sa position d'utilisation, et avantageusement consécutivement à la mise en place du parasol 1 selon l'invention sur le sol S, pour l'utilisation du parasol 1 selon l'invention, afin de créer une zone ombragée sur le sol S, à proximité du pied 2 du parasol 1 selon l'invention.This advantageous arrangement of the invention makes it possible to position the ribs 42e, 42i, in a position substantially parallel to the foot 2 of the parasol, as can be seen in the embodiment of the figure 7a , the fabric 3 being advantageously in the retracted position, in order to facilitate the handling of the parasol 1 according to the invention, when the latter is not in use, at an inclined position relative to the foot 2, as can be seen in the example of realization of the figure 7b , before effecting the passage of the canvas 3 from its retracted position to its position of use, and advantageously consecutively to the positioning of the parasol 1 according to the invention on the ground S, for the use of the parasol 1 according to the invention, in order to create a shaded area on the ground S, near the foot 2 of the parasol 1 according to the invention.

Comme visible sur les exemples de réalisation des figures la, 2, 3, 7a et 7b, ledit support 5 peut être réalisé sous la forme d'un étrier 5, notamment en matériau métallique, définissant une branche d'extrémité supérieure 51 et une branche d'extrémité inférieure 52, entre lesquelles sont positionnées les baleines 42e, 42i, les portions d'articulation 43 des baleines d'extrémité 42e étant positionnées contre lesdites extrémités supérieure 51 et inférieure 52 de l'étrier 5, avec un léger jeu permettant leur pivotement par rapport audit étrier 5 autour de l'axe 41.As can be seen in the embodiments of Figures 1a, 2, 3, 7a and 7b, said support 5 can be produced in the form of a bracket 5, in particular of metallic material, defining an upper end branch 51 and a branch lower end 52, between which are positioned the ribs 42e, 42i, the articulation portions 43 of the end ribs 42e being positioned against said upper 51 and lower 52 ends of the bracket 5, with a slight play allowing their pivoting relative to said caliper 5 about the axis 41.

Un perçage traversant peut être ménagé sur chacune des branches d'extrémité supérieure 51 et inférieure 52 de l'étrier 5, afin de permettre le passage de l'axe 41, afin de pouvoir assurer son maintien en position par rapport audit étrier 5, par l'intermédiaire d'éléments d'arrêt A41, positionnés aux extrémités de l'axe 41, et venant buter contre lesdites extrémités supérieure 51 et inférieure 52 de l'étrier 5.A through-hole can be made on each of the upper 51 and lower 52 end branches of the stirrup 5, in order to allow the passage of the pin 41, in order to be able to ensure that it is held in position with respect to said stirrup 5, by the intermediary of stop elements A41, positioned at the ends of the axis 41, and abutting against said upper 51 and lower 52 ends of the bracket 5.

Les branches d'extrémité supérieure 51 et inférieure 52 peuvent être reliées entre elles par une branche intermédiaire 53, configurée de sorte à assurer l'arrêt en position des baleines d'extrémité 42e, dans la position déployée de la toile 3, comme visible sur l'exemple de réalisation de la figure 2.The upper 51 and lower 52 end branches can be interconnected by an intermediate branch 53, configured so as to ensure the stopping in position of the end ribs 42e, in the deployed position of the canvas 3, as visible on the example of the figure 2 .

Une patte de fixation 54 avec un perçage traversant 55 peut être prévue, en saillie selon un plan perpendiculaire au plan de la branche intermédiaire 53, configurée pour être reçue dans ladite articulation 6.A fixing tab 54 with a through bore 55 may be provided, projecting along a plane perpendicular to the plane of the intermediate branch 53, configured to be received in said articulation 6.

L'emploi d'un tel support 5 sous la forme d'un étrier 5 permet également que l'axe 41 des moyens de fixation 4 des baleines 42e, 42i ne soit pas positionné dans le prolongement du pied 2, mais désaxé par rapport audit pied 2.The use of such a support 5 in the form of a stirrup 5 also allows the axis 41 of the fixing means 4 of the ribs 42e, 42i is not positioned in the extension of the foot 2, but offset relative to said. foot 2.

Ainsi, il est possible de positionner le parasol 1 selon l'invention sur le sol S, avec le pied 2 face au vent, avec l'axe 41 en arrière, par rapport à la direction du vent, ce qui diminue le risque de voir le parasol 1 s'envoler, une fois la toile 3 en position déployée.Thus, it is possible to position the parasol 1 according to the invention on the ground S, with the foot 2 facing the wind, with the axis 41 behind, relative to the direction of the wind, which reduces the risk of seeing the parasol 1 will fly away, once the canvas 3 is in the deployed position.

Ladite articulation 6 peut être fixée au niveau de l'extrémité supérieure 22 du pied 2, et peut comprendre deux pattes de fixation 61, parallèles entre elles, et recevant entre elles ladite patte de fixation 54 de l'étrier 5. Chacune desdites pattes de fixation 61 peut comporter un perçage traversant, configuré de sorte à coïncider avec ledit perçage traversant 55 de la patte de fixation 54, une fois reçue entre lesdites pattes de fixation 61 de l'articulation 6. Un axe 7 peut être prévu, par exemple sous la forme d'un boulon 7, comprenant un écrou 71 et une tige filetée 72, laquelle peut être reçue dans les perçages traversant desdites pattes de fixation 61 de l'articulation 6 et dans le perçage traversant 55 de l'étrier 5, afin de permettre le pivotement de l'étrier 5 par rapport à l'articulation 6, autour dudit axe A5.Said articulation 6 can be fixed at the level of the upper end 22 of the foot 2, and can comprise two fixing lugs 61, parallel to each other, and receiving between them said fixing lug 54 of the stirrup 5. Each of said brackets fixing 61 may comprise a through hole, configured so as to coincide with said through hole 55 of the fixing lug 54, once received between said fixing lugs 61 of the joint 6. An axis 7 may be provided, for example under the shape of a bolt 7, comprising a nut 71 and a threaded rod 72, which can be received in the holes passing through said fixing lugs 61 of the joint 6 and in the through hole 55 of the yoke 5, in order to allow the pivoting of the caliper 5 relative to the articulation 6, around said axis A5.

Avantageusement, et afin de faciliter l'assemblage du parasol 1 selon l'invention, l'écrou 71 du boulon 7 peut être un écrou à main.Advantageously, and in order to facilitate the assembly of the parasol 1 according to the invention, the nut 71 of the bolt 7 can be a hand nut.

Selon un mode de réalisation, les moyens de fixation 4 et la toile 3 sont configurés de sorte qu'en position déployée, les deux portions d'extrémité 31 de la toile 3 soient séparées par un espace vide V, définissant un secteur angulaire compris entre 90° et 120°.According to one embodiment, the fixing means 4 and the canvas 3 are configured so that, in the deployed position, the two end portions 31 of the canvas 3 are separated by an empty space V, defining an angular sector between 90 ° and 120 °.

Ainsi, comme visible sur l'exemple de réalisation de la figure 1b, la toile 3 du parasol 1 selon l'invention ne s'étend pas tout autour du pied 2, ce qui permet avantageusement de diminuer la prise au vent de la toile 3 du parasol 1, lorsque ladite toile 3 se trouve en position déployée, tout en garantissant une surface ombragée suffisante à proximité du pied 2 du parasol 1.Thus, as can be seen in the example of the realization of the figure 1b , the canvas 3 of the parasol 1 according to the invention does not extend all around the foot 2, which advantageously makes it possible to reduce the wind resistance of the canvas 3 of the parasol 1, when said canvas 3 is in the deployed position, while ensuring a sufficient shaded area near the foot 2 of the parasol 1.

A cet effet, et de façon avantageuse, le secteur angulaire de l'espace vide V peut être fixé par la position l'une par rapport à l'autre des branches d'extrémité 45E du ressort de torsion 45, et notamment l'angle entre ces deux branches d'extrémité 45E, lorsque la toile se trouve en position déployée.For this purpose, and advantageously, the angular sector of the empty space V can be fixed by the position relative to one another of the end branches 45E of the torsion spring 45, and in particular the angle between these two end branches 45E, when the canvas is in the deployed position.

Alternativement, ou en complément, ledit secteur angulaire de l'espace vide V peut être déterminé par l'étrier 5, et notamment sa branche intermédiaire 53, venant arrêter les portions d'articulation 43 des baleines d'extrémité 42e dans la position déployée de la toile 3 du parasol 1.Alternatively, or in addition, said angular sector of the empty space V can be determined by the stirrup 5, and in particular its intermediate branch 53, coming to stop the articulation portions 43 of the end ribs 42e in the deployed position of canopy 3 of parasol 1.

Alternativement, et sans sortir du cadre de la présente invention, la toile 3 peut être prévue pour s'étendre tout autour dudit pied 2, les branches d'extrémité 45E du ressort de torsion 45 pouvant alors être prévues en superposition l'une de l'autre, et/ou la branche intermédiaire 53 de l'étrier 5 peut être configurée de sorte à assurer l'arrêt des portions d'articulation 43 des baleines d'extrémité 42e, lorsque celles-ci sont sensiblement en superposition, au moins partiellement, l'une de l'autre.Alternatively, and without departing from the scope of the present invention, the canvas 3 may be provided to extend all around said foot 2, the end branches 45E of the torsion spring 45 then being able to be provided in superposition of one of the 'other, and / or the intermediate branch 53 of the yoke 5 can be configured so as to ensure the stopping of the articulation portions 43 of the end ribs 42e, when the latter are substantially in superposition, at least partially , one from the other.

Selon un mode de réalisation, les moyens de fixation 4 comprennent en outre un moyen de maintien 49, configuré pour maintenir la toile 3 en position escamotée.According to one embodiment, the fixing means 4 further comprise a holding means 49, configured to hold the canvas 3 in the retracted position.

Ainsi, le retrait dudit moyen de fixation 49 permet avantageusement le passage quasi-instantané de la toile 3 de la position escamotée à la position déployée de la toile 3.Thus, the withdrawal of said fixing means 49 advantageously allows the almost instantaneous passage of the canvas 3 from the retracted position to the deployed position of the canvas 3.

Comme visible sur l'exemple de réalisation de la figure la, et afin de simplifier la conception et diminuer le coût de revient du parasol 1 selon l'invention, ledit moyen de fixation 49 peut consister en un lien 49, avantageusement solidaire de la toile 3, configuré pour venir entourer les baleines 42e, 42i et la toile 3, lorsque celle-ci se trouve en position escamotée, la libération du lien 49 libérant le moyen élastique 45 et permettant le passage de la position escamotée à la position déployée de la toile 3.As can be seen in the embodiment of FIG. 1a, and in order to simplify the design and reduce the cost price of the parasol 1 according to the invention, said fixing means 49 may consist of a link 49, advantageously integral with the canvas. 3, configured to come around the ribs 42e, 42i and the canvas 3, when the latter is in the retracted position, the release of the link 49 releasing the elastic means 45 and allowing the passage from the retracted position to the deployed position of the canvas 3.

Naturellement, d'autres modes de réalisation auraient pu être envisagés par l'Homme du métier sans pour autant sortir du cadre de l'invention définie par les revendications ci-après.Naturally, other embodiments could have been envisaged by a person skilled in the art without however departing from the scope of the invention defined by the claims below.
