Description

L'invention est relative à un abri repliable, tel que parasol, abri de marché, abri de camping, ou similaire, destiné notamment à protéger des intempéries, soleil ou pluie une surface au sol. Elle trouve tout particulièrement son application chez les fabricants de parasols ou parapluies professionnels.The invention relates to a folding shelter, such as a parasol, market shelter, camping shelter, or the like, intended in particular to protect a ground surface from bad weather, sun or rain. It is particularly applicable to manufacturers of professional parasols or umbrellas.

Les marchands itinérants doivent en toute saison protéger les produits et articles à vendre tout en laissant un libre accès à leur clientèle. Ils doivent se prémunir aussi bien de la pluie que du soleil et l'abri utilisé à cet effet doit pouvoir être installé et démonté rapidement, de même qu'il doit occuper un faible volume durant le transport.Itinerant merchants must protect the products and items for sale in all seasons while leaving free access to their customers. They must protect themselves from both rain and sun and the shelter used for this purpose must be able to be installed and dismantled quickly, just as it must occupy a small volume during transport.

Actuellement, il existe principalement deux types d'abris de marché. Tout d'abord, on connaît les réalisations qui s'apparentent en ce qui concerne le type de construction aux tentes. Une structure rigide formée par un assemblage de tubes sert de soutien à une bâche. L'avantage de cette structure est qu'elle peut être de grandes dimensions et qu'elle présente une bonne rigidité. Démontée, elle occupe un faible volume. Par contre, ses inconvénients se situent au niveau du nombre de pièces à mettre en jeu très élevé et du temps de montage et de démontage.Currently, there are mainly two types of market shelters. First of all, we know the similar achievements with regard to the type of tent construction. A rigid structure formed by an assembly of tubes serves to support a tarpaulin. The advantage of this structure is that it can be large and that it has good rigidity. Disassembled, it occupies a small volume. On the other hand, its drawbacks lie in the number of parts to be brought into play very high and in the time of assembly and disassembly.

En raison des défauts énoncés précédemment, les commerçants s'orientent de plus en plus vers les structures en parapluie, comme montré par exemple dans le document FR-A-2 539 600, qui offrent l'avantage d'être très commodes dans leur mise en oeuvre. Les abris de marché en parapluie sont formés d'une toiture en toile soutenue par une armature rétractable montée à l'extrémité d'un mât de soutien qui repose sur le sol par l'intermédiaire d'un pied. Il suffit aux commerçants de déployer l'armature rétractable pour former une toiture efficace qui protège les marchandises contre la pluie et les rayons du soleil.Due to the faults stated above, traders are increasingly turning to umbrella structures, as shown for example in document FR-A-2,539,600, which offer the advantage of being very convenient in setting up. in action. Umbrella market shelters consist of a canvas roof supported by a retractable frame mounted at the end of a support pole which rests on the ground by means of a foot. Merchants simply deploy the retractable frame to form an effective roof that protects goods from rain and direct sunlight.

Bien que nettement plus pratique que la structure tubulaire assemblée, l'armature rétractable souffre néanmoins de quelques défauts. En particulier, pour maintenir le mât vertical, on utilise soit une embase séparée lourde, soit des pieds articulés à trois ou quatre branches. Toutefois, quel que soit le cas, ces pieds ou embases sont toujours séparés du mât, comme montré par exemple dans le document FR-A-551 218.Although much more practical than the assembled tubular structure, the retractable frame nevertheless suffers from some faults. In particular, to keep the mast vertical, either a separate heavy base is used, or articulated feet with three or four branches. However, whatever the case, these feet or bases are always separated from the mast, as shown for example in the document FR-A-551 218.

Dans le cas de l'embase lourde, de son poids dépend la stabilité de l'ensemble, mais cela se répercute sur la manutention.In the case of the heavy base, its weight depends on the stability of the assembly, but this affects handling.

Dans le cas du pied articulé séparé, il est nécessaire de l'ouvrir à la façon d'un parapluie inversé, puis de le fixer en position ouverte et enfin de venir emmancher le mât de l'abri et de le solidariser par rapport aux pieds.In the case of the separate articulated foot, it is necessary to open it in the manner of an inverted umbrella, then to fix it in the open position and finally to come to grip the mast of the shelter and to secure it in relation to the feet .

Le transport et la mise en place de cette embase ou pied ne sont guère commodes. Par exemple, lorsque la toile est mouillée après une pluie, l'ensemble s'alourdit et le commerçant a beaucoup de difficultés pour manoeuvrer le mât, et pour mettre en place le pied.The transport and the installation of this base or foot are hardly convenient. For example, when the canvas is wet after a rain, the assembly becomes heavier and the trader has great difficulty in maneuvering the mast, and in setting up the foot.

Pour compléter la stabilité de tels abris, et pour éviter de déformer la structure lors d'un vent important, il est nécessaire de mettre en place des dispositifs particuliers, tels que des dispositifs de lestage accrochés à l'extrémité des baleines formant la structure.To complete the stability of such shelters, and to avoid deforming the structure during a strong wind, it is necessary to put in place special devices, such as ballasting devices hung on the end of the whales forming the structure.

Plus précisément, on utilise, soit une corde, soit un hauban rigide que l'on relie d'un côté à l'extrémité de la baleine et de l'autre côté à des lests posés au sol.More precisely, either a rope or a rigid guy wire is used which is connected on one side to the end of the whale and on the other side to weights placed on the ground.

Ainsi, lors du montage et du démontage de l'abri, il est nécessaire d'aller accrocher et décrocher respectivement les lests. De même, lors du stockage de l'abri replié, les haubans sont donc indépendants de la structure ; ou, dans le cas des cordes, celles-ci sont enroulées sur les extrémités des baleines.Thus, during the assembly and disassembly of the shelter, it is necessary to go to hook and unhook the weights respectively. Similarly, during storage of the folded shelter, the shrouds are therefore independent of the structure; or, in the case of ropes, these are wound on the ends of the whales.

On connait aussi, par le document US-A-3 213 868, un abri du type parapluie comportant un pied déployable sous la commande d'un vérin à fluide ou à vis, assurant la manoeuvre simultanée du pied et du parapluie lui-même, mais cet agencement est complexe, coûteux et non automatique.We also know, from document US-A-3,213,868, an umbrella type shelter comprising a deployable foot under the control of a fluid or screw jack, ensuring the simultaneous operation of the foot and of the umbrella itself, but this arrangement is complex, expensive and not automatic.

Le but principal de la présente invention est de fournir un abri repliable tel que parasol, abri de marché, abri de camping ou similaire, de type à armature rétractable qui présente une grande simplicité de mise en place. En particulier, la stabilité verticale du mât n'est plus assurée par un piétement rapporté mais grâce à un pied à déploiement automatique.The main object of the present invention is to provide a folding shelter such as a parasol, market shelter, camping shelter or the like, of the retractable frame type which is very simple to set up. In particular, the vertical stability of the mast is no longer ensured by an attached base but thanks to an automatic deployment foot.

Ainsi, lorsque le mât est en contact avec le sol, le pied se déploie sans aucune intervention directe. De même, lorsque l'on soulève le mât du sol après déverrouillage, le pied se rétracte sans aucune intervention extérieure. De ce fait, l'utilisateur peut sans aide manoeuvrer son abri repliable.Thus, when the mast is in contact with the ground, the foot is deployed without any direct intervention. Similarly, when the mast is lifted from the ground after unlocking, the foot retracts without any external intervention. As a result, the user can, without assistance, maneuver his folding shelter.

Il faut souligner que cette simplicité de fonctionnement n'est pas obtenue au détriment de la stabilité de l'ensemble. Bien au contraire, le pied du mât peut être de grandes dimensions et offrir ainsi une bonne assise avec un faible encombrement lorsqu'il est rétracté.It should be emphasized that this simplicity of operation is not obtained at the expense of the stability of the assembly. On the contrary, the mast foot can be large and thus provide a good seat with a small footprint when it is retracted.

Un autre but de la présente invention est de présenter un abri repliable du type à armature rétractable dont le déploiement est facilité par la structure mécanique de la présente invention.Another object of the present invention is to present a folding shelter of the type with retractable frame, the deployment of which is facilitated by the mechanical structure of the present invention.

En effet, dans les structures traditionnelles, on fait coulisser une virole sur un mât central, ce qui a pour effet de déployer les baleines par l'intermédiaire d'un tirant fixé entre la virole et la partie médiane de chaque baleine. L'effort développé est tel qu'il est courant de démultiplier la commande par l'intermédiaire d'un câble et de poulies de renvoi.Indeed, in traditional structures, a ferrule is made to slide on a central mast, which has the effect of deploying the whales by means of a tie rod fixed between the ferrule and the middle part of each whale. The effort developed is such that it is common to multiply the control by means of a cable and pulleys.

Un autre but de la présente invention est de proposer un abri repliable permettant de remédier à cet inconvénient, qui autorise notamment une ouverture de la structure avec un effort réduit.Another object of the present invention is to provide a folding shelter making it possible to remedy this drawback, which in particular allows the structure to be opened with reduced effort.

De plus, la structure de l'armature formant la toiture est renforcée afin de mieux répartir sur les baleines les efforts dus à l'ouverture et/ou au soutien de la toile de toiture.In addition, the structure of the frame forming the roof is reinforced in order to better distribute over the whales the forces due to the opening and / or support of the roofing fabric.

Un autre but de la présente invention est de fournir un abri de marché qui dispose d'un dispositif d'accrochage des lests de baleine intégrés. Ainsi, les risques d'emmêlage des haubans sont écartés.Another object of the present invention is to provide a market shelter which has a device for hanging integrated whale weights. Thus, the risks of tangling of the shrouds are eliminated.

Plus particulièrement, l'abri repliable de la présente invention permet un escamotage des haubans à l'intérieur de la structure lors du repli de l'abri et une mise en place automatique de ceux-ci lors du déploiement de la toiture.More particularly, the folding shelter of the present invention allows retraction of the shrouds inside the structure during the folding of the shelter and an automatic positioning of these during the deployment of the roof.

L'abri repliable tel que parasol, abri de marché, abri de camping ou similaire, selon l'invention, destiné notamment à protéger des intempéries, soleil ou pluie, une surface au sol, qui est formé d'une toiture en toile soutenue par une armature rétractable montée sur un mât qui repose sur le sol par l'intermédiaire d'un pied, est caractérisé par le fait que le pied comporte des moyens de déploiement de celui ci actionnés par simple contact avec le sol sous l'effet du poids de l'abri.The folding shelter such as parasol, market shelter, camping shelter or the like, according to the invention, intended in particular to protect from bad weather, sun or rain, a ground surface, which is formed by a canvas roof supported by a retractable frame mounted on a mast which rests on the ground by means of a foot, is characterized in that the foot comprises means for deploying the latter actuated by simple contact with the ground under the effect of the weight from the shelter.

D'autres buts et avantages de la présente invention apparaitront au cours de la description qui va suivre qui n'est cependant donnée qu'à titre indicatif et qui n'a pas pour but de la limiter.Other objects and advantages of the present invention will appear during the description which follows which is however given only for information and which is not intended to limit it.

L'invention sera mieux comprise à la lecture de la description suivante accompagnée des dessins annexés dans lesquels :

  • a Figure 1 montre en perspective un abri repliable selon l'invention ;
  • la Figure 2 montre, à plus grande échelle et en coupe axiale, la structure du pied en position repliée ;
  • la Figure 3 est une vue analogue à la Figure 2 pour la position déployée ; et
  • la Figure 4 montre l'ensemble de l'abri de la Figure 1 avec son dispositif de lestage et à l'état déployé.
The invention will be better understood on reading the following description accompanied by the appended drawings in which:
  • a Figure 1 shows in perspective a folding shelter according to the invention;
  • Figure 2 shows, on a larger scale and in axial section, the structure of the foot in the folded position;
  • Figure 3 is a view similar to Figure 2 for the deployed position; and
  • Figure 4 shows the entire shelter of Figure 1 with its ballasting device and in the deployed state.

L'invention est relative à un abri repliable tel que parasol, abri de marché, de camping, ou similaire, destiné notamment à protéger des intempéries, soleil ou pluie une surface au sol. Elle concerne plus particulièrement les fabricants de parasols, parapluies et autres.The invention relates to a folding shelter such as a parasol, market shelter, camping shelter, or the like, intended in particular to protect from the weather, sun or rain a ground surface. It concerns more particularly the manufacturers of parasols, umbrellas and others.

La Figure 1 schématise un abri 1 rétractable, notamment pour marché, tel qu'envisagé par la présente invention. Cet abri 1 est formé d'une toiture 2 en toile de forme quelconque ; une forme allongée telle que rectangulaire ou ovale est préférée pour couvrir des étals de commerce. Cette toiture 2 est soutenue par une armature 3 rétractable (Figure 4), c'est-à-dire qu'elle permet d'étendre la toile 2 ou au contraire de la rabattre contre un mât de soutien 4.Figure 1 shows schematically a retractable shelter 1, especially for market, as envisaged by the present invention. This shelter 1 is formed by a roof 2 of canvas of any shape; an elongated shape such as rectangular or oval is preferred for covering commercial stalls. This roof 2 is supported by a retractable frame 3 (FIG. 4), that is to say that it makes it possible to extend the fabric 2 or, on the contrary, to fold it down against a support mast 4.

Le mât 4 repose sur le sol par l'intermédiaire d'un pied 5 formé d'une série de branches 6 disposées radialement en étoile autour du mât 4 pour donner une bonne stabilité à l'abri.The mast 4 rests on the ground by means of a foot 5 formed by a series of branches 6 arranged radially in a star around the mast 4 to give good stability to the shelter.

Par ailleurs, des lests 7 sont fixés par l'intermédiaire de haubans 8 aux extrémités des baleines 16 de soutien de la toile 2 pour éviter qu'en période de grand vent la toile 2 ne puisse être retournée.Furthermore, weights 7 are fixed by means of shrouds 8 to the ends of the ribs 16 for supporting the fabric 2 to prevent the fabric 2 from being able to be turned over during periods of strong wind.

Selon la caractéristique principale de la présente invention, le pied 5 présente des moyens de déploiement actionnés par simple contact avec le sol sous l'effet du poids de l'abri. Ainsi, l'utilisateur peut très facilement mettre en place l'abri sans aucune aide extérieure, même lorsque la toile est mouillée, car il lui suffit d'appliquer l'extrémité inférieure du mât 4 contre le sol pour que les branches 6 du pied 5 se déploient et donnent une bonne stabilité verticale à l'abri.According to the main characteristic of the present invention, the foot 5 has deployment means actuated by simple contact with the ground under the effect of the weight of the shelter. Thus, the user can very easily set up the shelter without any outside help, even when the canvas is wet, because he only has to apply the lower end of the mast 4 against the ground so that the branches 6 of the foot 5 deploy and give good vertical stability to the shelter.

En particulier, les moyens de déploiement agissent sous l'effet de la pesanteur lorsque le mât 4 vient en contact avec le sol, le poids du mât 4, de l'armature 3, et de la toile 2 agissant pour l'ouverture du pied 5.In particular, the deployment means act under the effect of gravity when the mast 4 comes into contact with the ground, the weight of the mast 4, of the frame 3, and of the fabric 2 acting for the opening of the foot 5.

Grâce à l'invention, l'action inverse se produit également : lors du soulèvement du mât, les moyens de deploiement agissent pour rétracter les branches 6 du pied 5 contre le mât 4.Thanks to the invention, the reverse action also occurs: when the mast is raised, the deployment means act to retract the branches 6 of the foot 5 against the mast 4.

La Figure 2 schématise le pied 5 en position rétractée. Le pied 5 comprend des branches radiales 6 articulées à l'extrémité d'un embout 9 mobile axialement à l'extrémité inférieure du mât 4. Des bielles 10 articulées à chaque extrémité relient les branches 6 du pied 5 à la partie inférieure 11 du mât 4. En outre, un dispositif de rappel 12, tel qu'un ressort de compression, repousse l'embout 9 vers le bas, de telle sorte que les branches 6 restent repliées contre le mât 4 en l'absence de toute force extérieure. Le ressort 12 est disposé entre l'extrémité inférieure du mât et une tête 9a prévue à l'extrémité inférieure d'une tige 9b de l'embout 9. Le cas échéant, le ressort 12 pourrait être agencé et monté pour agir avec dépassement de point neutre, de façon à solliciter le pied 5 en position d'ouverture et de fermeture de part et d'autre de ce point neutre.Figure 2 shows diagrammatically the foot 5 in the retracted position. The foot 5 comprises radial branches 6 articulated at the end of a tip 9 movable axially at the lower end of the mast 4. Connecting rods 10 articulated at each end connect the branches 6 of the foot 5 to the lower part 11 of the mast 4. In addition, a return device 12, such as a compression spring, pushes the end piece 9 downwards, so that the arms 6 remain folded against the mast 4 in the absence of any external force. The spring 12 is disposed between the lower end of the mast and a head 9a provided at the lower end of a rod 9b of the end piece 9. If necessary, the spring 12 could be arranged and mounted to act with overshoot of neutral point, so as to urge the foot 5 in the open and closed position on either side of this neutral point.

Selon le mode de réalisation envisagé ici, l'embout mobile 9 coulisse à l'intérieur du mât tubulaire 4 par sa tige 9b.According to the embodiment envisaged here, the movable end piece 9 slides inside the tubular mast 4 by its rod 9b.

Lorsque l'on exerce un effort axial vers le haut sur la tête 9a de l'embout 9, comme cela se rencontre lorsque l'on pose le mât 4 sensiblement verticalement sur le sol, on provoque la rentrée de l'embout 9 dans le mât tubulaire 4. Le ressort 12 se comprime et les branches 6 du pied 5 se déploient jusqu'à entrer en contact avec le sol comme cela est illustré par exemple sur la Figure 3.When an axial upward force is exerted on the head 9a of the end piece 9, as is encountered when the mast 4 is placed substantially vertically on the ground, the end piece 9 is brought into the tubular mast 4. The spring 12 is compressed and the legs 6 of the foot 5 extend until they come into contact with the ground as illustrated for example in FIG. 3.

Le déploiement des branches 6 est dû à l'action des bielles 11 qui repoussent les branches 6 durant la rentrée de l'embout 9 dans le mât tubulaire 4 contre l'action du ressort 12 dont l'action est juste suffisante pour assurer la rétraction normale du pied (Figure 2).The deployment of the branches 6 is due to the action of the connecting rods 11 which push the branches 6 during the retraction of the end piece 9 in the tubular mast 4 against the action of the spring 12 whose action is just sufficient to ensure retraction normal foot (Figure 2).

On peut renforcer la stabilité du pied 5 en ajoutant des bielles supplémentaires 13 articulées d'une part aux branches 6 et d'autre part à une virole 14 qui coulisse extérieurement le long du mât 4.The stability of the foot 5 can be reinforced by adding additional connecting rods 13 articulated on the one hand to the arms 6 and on the other hand to a ferrule 14 which slides outwardly along the mast 4.

Pour éviter tout repliage accidentel du pied 5, on peut avantageusement prévoir un organe de verrouillage 15 qui peut par exemple se présenter sous la forme d'une vis ou broche transversale, telle qu'illustrée à la Figure 3, qui s'appuie ou traverse l'embout 9.To avoid any accidental folding of the foot 5, it is advantageously possible to provide a locking member 15 which may for example be in the form of a transverse screw or pin, as illustrated in FIG. 3, which is supported or traversed end piece 9.

On peut également prévoir un dispositif de blocage de la virole 14, ce qui présente le double avantage d'éviter le repliage accidentel du pied 5 et d'améliorer l'action stabilisatrice des bielles complémentaires 13.It is also possible to provide a device for blocking the ferrule 14, which has the double advantage of avoiding accidental folding of the foot 5 and of improving the stabilizing action of the complementary connecting rods 13.

En outre, pour conforter la stabilité de l'abri, on peut par exemple lester le pied à l'aide d'un poids 25 représenté en tirets sur la Figure 3. Un tel lest peut par exemple être constitué par un tore pesant apte à s'adapter autour du mât tubulaire 4 et à s'appuyer sur la virole 14. Un tel lestage peut, dans certains cas, rendre les lests 7 inutiles ; toutefois, on peut utiliser ces lestages en complément.In addition, to consolidate the stability of the shelter, it is possible, for example, to ballast the foot using a weight 25 shown in dashes in FIG. 3. Such a ballast can for example consist of a heavy toroid capable of fit around the tubular mast 4 and rest on the ferrule 14. Such ballasting can, in certain cases, make ballast 7 useless; however, these weights can be used in addition.

Selon une autre caractéristique de l'invention, les moyens de déploiement du pied 5 forment une butée mobile d'ouverture pour l'armature rétractable 3. Il s'agit d'une conception de l'armature rétractable particulière tout à fait adaptée pour soutenir des toiles de grandes dimensions.According to another characteristic of the invention, the means for deploying the foot 5 form a movable opening stop for the retractable frame 3. It is a design of the particular retractable frame quite suitable for supporting large canvases.

Les techniques courantes de construction d'armatures de parapluie ou parasol emploient un seul jeu de bielles de soutien des baleines, ce qui s'avère insuffisant pour des toiles de grandes dimensions, de l'ordre de 3 m x 4 m.Current techniques for constructing umbrella or parasol frames use a single set of rods for supporting the whales, which is insufficient for large canvases, of the order of 3 mx 4 m.

Selon la conception envisagée pour la réalisation de l'armature rétractable 3 de l'abri de marché 1 de la présente invention, les baleines 16 sont soutenues par un double système de tringlerie, tel que cela est illustré à la Figure 4.According to the design envisaged for the production of the retractable frame 3 of the market shelter 1 of the present invention, the ribs 16 are supported by a double linkage system, as illustrated in FIG. 4.

L'armature 3 est formée de baleines 16 articulées sur la tête 17a prévue à l'extrémité supérieure d'un embout télescopique 17 placé à l'extrémité supérieure du mât 4. Par ailleurs, les baleines 16 sont soutenues par des bielles articulées 18 montées entre les baleines 16 et une virole 19 coulissant le long du mât 4.The frame 3 is formed of ribs 16 articulated on the head 17a provided at the upper end of a telescopic end piece 17 placed at the upper end of the mast 4. Furthermore, the ribs 16 are supported by articulated connecting rods 18 mounted between the whales 16 and a ferrule 19 sliding along the mast 4.

Le soutien des bielles 18 est assuré par des biellettes 20 qui sont montées et articulées à une extrémité sur la partie centrale des bielles 18 sur lesquelles elles prennent appui et qui sont articulées à l'autre extrémité sur l'extrémité supérieure du mât 4, autour d'une articulation 21.The rods 18 are supported by rods 20 which are mounted and articulated at one end on the central part of the rods 18 on which they bear and which are articulated at the other end on the upper end of the mast 4, around a joint 21.

Le déploiement de l'armature 3 s'obtient en faisant glisser la virole 19 vers le haut le long du mât 4, ce qui provoque la rotation des biellettes 20 et des bielles 18, et par conséquent le déploiement des baleines 16, accompagné d'un mouvement de rentrée de la tige 17b de l'embout télescopique 17 dans le mât 4.The deployment of the frame 3 is obtained by sliding the ferrule 19 upwards along the mast 4, which causes the rotation of the rods 20 and rods 18, and consequently the deployment of the ribs 16, accompanied by a reentry movement of the rod 17b of the telescopic endpiece 17 in the mast 4.

Ainsi, selon la présente invention, contrairement aux systèmes existants qui nécessitent une force importante pour l'ouverture de l'armature portant la toile, la structure permet avantageusement de faciliter l'ouverture par le système articulé bielles 18-biellettes 20-baleines 16, aidé en outre par l'abaissement dans le mât tubulaire 4 de l'embout télescopique 17 qui joue alors un rôle de contrepoids.Thus, according to the present invention, unlike existing systems which require a large force to open the frame carrying the fabric, the structure advantageously makes it possible to facilitate opening by the articulated system connecting rods 18-rods 20-whales 16, aided further by the lowering in the tubular mast 4 of the telescopic end piece 17 which then acts as a counterweight.

Après avoir pénétré dans le mât 4, la tige 17b de l'embout 17 vient en butée sur la tige 9b de l'embout 9, comme montré en 26 sur la Figure 4, ce qui limite le déploiement de l'armature rétractable. Pour éviter la descente de la virole 19 après ouverture de l'armature 3, on immobilise la translation relative, soit de la virole 19 par rapport au tube 4, soit de l'embout 17 par rapport au tube 4 par tout moyen approprié tel qu'une broche transversale ou autre (non représenté).After entering the mast 4, the rod 17b of the end piece 17 abuts on the rod 9b of the end piece 9, as shown at 26 in Figure 4, which limits the deployment of the retractable frame. To avoid the descent of the ferrule 19 after opening of the frame 3, the relative translation is immobilized, either of the ferrule 19 relative to the tube 4, or of the end piece 17 relative to the tube 4 by any suitable means such as a transverse pin or the like (not shown).

Dans un autre mode de réalisation, on pourrait également envisager le verrouillage de l'abri en position déployée par une tringle qui relierait le sommet du mât, et plus précisément la tête 17a de l'embout 17, au pied, et plus précisément à la tête 9a de l'embout 9 du pied. La longueur de cette tringle de verrouillage est naturellement définie selon les cas afin que les deux embouts 9 et 17 viennent en butée en 26 à l'intérieur du mât 4.In another embodiment, one could also consider locking the shelter in the deployed position by a rod which would connect the top of the mast, and more precisely the head 17a of the end piece 17, at the foot, and more precisely to the head 9a of the tip 9 of the foot. The length of this locking rod is naturally defined according to the case so that the two end pieces 9 and 17 come into abutment at 26 inside the mast 4.

De même que pour le pied, on pourrait envisager d'utiliser un dispositif de rappel, éventuellement à dépassement de point neutre, dans le système d'ouverture de l'armature 3 afin de faciliter la manoeuvre. Tout dispositif connu tel que ressort, vérin, pourrait être employé à cet effet.As for the foot, one could consider using a return device, possibly beyond the neutral point, in the opening system of the frame 3 in order to facilitate the maneuver. Any known device such as spring, cylinder, could be used for this purpose.

On peut avantageusement équiper l'armature d'un dispositif évitant par période de grand vent que la toile ne puisse se retourner. Selon l'invention, ce dispositif comprend des lests 7 suspendus, de manière amovible, par l'intermédiaire de mousquetons 22 à l'extrémité de haubans 8.It is advantageously possible to equip the frame with a device preventing, during periods of high wind, that the fabric cannot turn over. According to the invention, this device comprises ballast weights which are removably suspended by means of snap hooks 22 at the end of the shrouds 8.

Le hauban 8 est avantageusement réalisé par une tige ou un tube rigide solidarisé à l'extrémité des ou de certaines baleines 16. De plus, autour de cette baleine est prévu un oeillet 24 qui permet, après avoir désolidarisé le lest 7 au niveau du mousqueton 22, de placer le hauban 8 en position sensiblement parallèle à la baleine, comme le montre la ligne en tirets de la Figure 4. Ainsi, avant le repliage de l'abri de la présente invention, on place le hauban 8 de telle façon que le mousqueton 22 vienne au niveau du centre de la structure du toit. Le maintien du hauban peut être réalisé grâce à l'oeillet 24 qui vient coopérer dans une encoche au niveau de la baleine.The shroud 8 is advantageously made by a rigid rod or tube secured to the end of the or certain whales 16. In addition, around this whale is provided an eyelet 24 which allows, after having detached the ballast 7 at the carabiner 22, to place the shroud 8 in a position substantially parallel to the whale, as shown by the dashed line in Figure 4. Thus, before folding the shelter of the present invention, the shroud 8 is placed so that the carabiner 22 comes at the center of the roof structure. The stay can be maintained using the eyelet 24 which cooperates in a notch at the level of the whale.

L'abri peut ensuite être replié et, lors de ce repliage, l'oeillet 24 quittant l'encoche coulisse le long de la baleine 16 pour revenir de par son poids vers le bas de la baleine. Le hauban 8 est maintenu par la structure repliée mais, lors d'un nouveau déploiement de la structure, le hauban revient naturellement en position verticale sans manoeuvre complémentaire pour une nouvelle utilisation.The shelter can then be folded and, during this folding, the eyelet 24 leaving the notch slides along the whale 16 to return by its weight to the bottom of the whale. The shroud 8 is held by the folded structure but, during a new deployment of the structure, the shroud naturally returns to the vertical position without additional operation for a new use.
