Description

Domaine techniqueTechnical area

La présente invention concerne un abri léger comprenant un ensemble support d'un élément de toiture comportant un cadre et une toile destinée à être tendue entre le cadre et l'ensemble support et le procédé de montage associé.The present invention relates to a lightweight shelter comprising a support assembly of a roof element comprising a frame and a fabric to be stretched between the frame and the support assembly and the associated mounting method.

Technique antérieurePrior art

Dans le domaine de ce type d'abri, on connait déjà un abri de type à mât central tel que celui décrit dans la demande de brevet européen EP 1 932 983 déposée au nom de la demanderesse. Cet abri 101 selon l'état de la technique est représenté sur la figure 1 et comporte un ensemble support 102, un élément de toiture comportant un cadre 103 en forme de quadrilatère et une toile 104 fixée par sa partie périphérique externe sur le cadre 103 et destinée à être tendue entre ledit cadre 103 et l'ensemble support 102.In the field of this type of shelter, we already know a shelter type central mast as described in the European patent application EP 1 932 983 filed in the name of the plaintiff. This shelter 101 according to the state of the art is represented on the figure 1 and comprises a support assembly 102, a roof element comprising a quadrilateral-shaped frame 103 and a wire 104 fixed by its outer peripheral portion to the frame 103 and intended to be stretched between said frame 103 and the support assembly 102.

Ledit ensemble support 102 comprend un mât central 105, une cerce 106 montée coulissante, apte à être verrouillée sur ledit mât central 105 et agencée pour recevoir la partie centrale de ladite toile 104, une bride 107 fixée sur la partie supérieure dudit mât central 105, ladite bride 107 comportant un ensemble de poulies 108 radiales aptes à recevoir chacune un câble 109, et une bague de tension 110 montée coulissante et apte à être verrouillée sur ledit mât central 105.Said support assembly 102 comprises a central mast 105, a hinge 106 mounted slidably, able to be locked on said central mast 105 and arranged to receive the central portion of said web 104, a flange 107 fixed on the upper part of said central mast 105, said flange 107 comprising a set of radial pulleys 108 each capable of receiving a cable 109, and a tensioning ring 110 slidably mounted and able to be locked on said central mast 105.

Chaque câble 109 passe sur une des poulies 108 et a une première extrémité fixée à la bague de tension 110 et une deuxième extrémité fixée au cadre 103, ladite bague de tension 110 de l'ensemble support 102 étant verrouillée sur le mât central 105 dans une position telle que les câbles 109 soient tendus.Each cable 109 passes over one of the pulleys 108 and has a first end attached to the tension ring 110 and a second end attached to the frame 103, said tension ring 110 of the support assembly 102 being locked to the central mast 105 in a position such as cables 109 are stretched.

Le montage de cet abri se déroule de la manière suivante. L'ensemble support 102, comprenant le mât central 105, la cerce 106, la bride 107, la bague de tension 110 et les câbles 109, est érigé. Le cadre 103 est ensuite disposé ou assemblé autour dudit ensemble support 102. La deuxième extrémité de chaque câble 109 de l'ensemble support 102 est alors fixée à des points de fixation 111 prévus sur le cadre 103. La toile 104 est fixée sur le cadre 103 par sa périphérie externe et sur la cerce 106 par sa périphérie interne définie par sa partie centrale. La bague de tension 110 est tirée vers le bas pour, d'une part, lever le cadre 103 et, d'autre part, tendre la toile 104 en poussant la cerce 106 vers le bas. Enfin, une fois la tension de toile souhaitée obtenue, la bague de tension 110 est verrouillée sur le mât central 105 dans la position finale désirée.The assembly of this shelter takes place in the following way. The support assembly 102, comprising the central mast 105, the hoop 106, the flange 107, the tension ring 110 and the cables 109, is erected. The frame 103 is then arranged or assembled around said support assembly 102. The second end of each cable 109 of the support assembly 102 is then fixed to fixing points 111 provided on the frame 103. The fabric 104 is fixed on the frame 103 by its outer periphery and on the circle 106 by its inner periphery defined by its central part. The tension ring 110 is pulled downwardly, on the one hand, to lift the frame 103 and, on the other hand, tension the fabric 104 by pushing the ring 106 downwards. Finally, once the desired fabric tension obtained, the tension ring 110 is locked on the central mast 105 in the desired final position.

L'ensemble support 102 selon l'état de la technique présente un certain nombre d'inconvénients. En effet, du fait de son nombre d'éléments constitutifs et de leur complexité, cet ensemble support 102 est particulièrement difficile et onéreux à réaliser et à mettre en oeuvre.The support assembly 102 according to the state of the art has a number of disadvantages. Indeed, because of its number of constituent elements and their complexity, this support assembly 102 is particularly difficult and expensive to achieve and implement.

Par ailleurs, lors de la fixation de la deuxième extrémité de chaque câble 109 de l'ensemble support 102 sur le cadre 103 à des points de fixation 111, si on échappe ledit câble 109 et que ce dernier se dégage de sa poulie 108 et tombe à terre, il faut alors prendre une échelle ou un échafaudage pour engager à nouveau le câble 109 dans sa poulie 108 et le fixer sur le cadre 103, car les poulies 108 sont solidaires de la bride 107 fixée sur la partie supérieure dudit mât central 105. Cette manipulation doit être réalisée avec beaucoup d'attention afin d'éviter une augmentation du coût de montage due à l'augmentation des heures de montage et l'emploi de matériels supplémentaires.On the other hand, when fixing the second end of each cable 109 of the support assembly 102 on the frame 103 at attachment points 111, if said cable 109 is escaped and the cable 109 disengages from its pulley 108 and falls on the ground, it is then necessary to take a ladder or a scaffold to engage the cable 109 again in its pulley 108 and fix it on the frame 103, since the pulleys 108 are integral with the flange 107 fixed on the upper part of said central mast 105 This manipulation must be carried out with great care in order to avoid an increase in the cost of assembly due to the increase of the assembly hours and the use of additional materials.

Enfin, pour les abris 101 de grandes dimensions, la plupart des éléments constitutifs, en particulier le mât central 105, sont de grande longueur et nécessitent pour leur mise en place des engins de manutentions de grande capacité et pour leur transport des emballages gros volume particulièrement onéreux notamment lorsqu'il s'agit de caisses maritimes par exemple.Finally, for large shelters 101, most of the constituent elements, in particular the central mast 105, are of great length and require for their installation high capacity handling equipment and for their transport of particularly large volume packaging. expensive in particular when it comes to maritime funds for example.

Exposé de l'inventionPresentation of the invention

Le but de la présente invention est donc de pallier les inconvénients précédemment cités et de proposer un abri léger du type à mât central comportant un ensemble support d'un élément de toiture, dont la structure est telle que, d'une part, le transport et le montage dudit abri sont avantageusement plus faciles du fait notamment de la longueur réduite de différentes pièces et, d'autre part, les assemblages des différents éléments entre eux ne nécessitent pas d'avoir recours à des outillages spécifiques et des personnels qualifiés tout en étant parfaitement sécurisés.The purpose of the present invention is therefore to overcome the aforementioned drawbacks and to provide a lightweight shelter of the central mast type comprising a support assembly of a roof element, whose structure is such that, on the one hand, the transport and the mounting of said shelter are advantageously easier due in particular to the reduced length of different parts and, on the other hand, the assemblies of the various elements between them do not require the use of specific tools and qualified personnel while being perfectly secure.

Conformément à l'invention, il est donc proposé un abri léger comportant un élément de toiture supporté par un ensemble support et formé par un cadre et une toile fixée par son bord périphérique extérieur sur ledit cadre et tendue entre ledit cadre et l'ensemble support, ledit ensemble support comprenant un mât central, des moyens de liaison montés coulissants sur ledit mât central et agencés pour recevoir le bord périphérique intérieur de la toile et pour être verrouillés sur ledit mât central après tension de ladite toile, une bride montée coulissante sur ledit mât central et agencée pour être bloquée à l'extrémité haute du mât central par des moyens de verrouillage, et une pluralité de câbles dont l'une des extrémités est fixée sur ladite bride l'autre étant fixée sur le cadre, ledit mât central étant télescopique et comportant au moins un élément inférieur tubulaire fixé au sol et un élément supérieur agencé pour coulisser à l'intérieur dudit élément inférieur entre une "position rentrée" dans laquelle ledit élément supérieur est disposé entièrement ou en majeure partie dans ledit élément inférieur, et une "position sortie" dans laquelle ledit élément supérieur est disposé en majeure partie hors dudit élément inférieur, ledit élément supérieur étant verrouillé en "position sortie" par au moins des moyens de blocage. Ledit abri est remarquable en ce que les moyens de blocage comportent avantageusement au moins un organe de blocage apte à coopérer avec un premier orifice traversant entièrement l'extrémité basse de l'élément supérieur et en ce que ledit organe de blocage comprend deux viroles agencées pour être fixées autour de la jonction des éléments inférieur et supérieur et un goujon solidaire d'une des viroles et apte à coopérer simultanément avec ledit premier orifice de l'élément supérieur et un orifice de l'autre virole, ledit goujon venant, dans la "position sortie", en appui sur la face annulaire de l'extrémité haute de l'élément inférieur du mât central.According to the invention, it is therefore proposed a lightweight shelter comprising a roof element supported by a support assembly and formed by a frame and a fabric fixed by its outer peripheral edge on said frame and stretched between said frame and the support assembly , said support assembly comprising a central mast, connecting means slidably mounted on said central mast and arranged to receive the inner peripheral edge of the fabric and to be locked on said central mast after tensioning said fabric, a flange slidably mounted on said central mast and arranged to be locked at the upper end of the central mast by locking means, and a plurality of cables whose one end is fixed on said flange the other being fixed to the frame, said central mast being telescopic and having at least one tubular lower member fixed to the ground and an upper member arranged to slide inside said lower member between a "retracted position" in which said upper member is disposed wholly or substantially in said lower member, and an "extended position" in which said upper member is disposed substantially out of said lower member, said upper member being locked in "extended position" by at least one means blocking. Said shelter is remarkable in that the blocking means advantageously comprise at least one locking member adapted to cooperate with a first orifice entirely passing through the lower end of the upper element and in that the said locking member comprises two ferrules arranged to to be fixed around the junction of the lower and upper elements and a bolt secured to one of the ferrules and able to cooperate simultaneously with said first orifice of the upper element and an orifice of the other ferrule, said stud coming into the " output position ", resting on the annular face of the upper end of the lower element of the central mast.

Selon un mode de réalisation avantageux, les moyens de verrouillage comprennent une butée disposée à l'extrémité haute de l'élément supérieur, un deuxième orifice traversant entièrement l'extrémité haute de l'élément supérieur et disposé sous ladite butée, et un organe de verrouillage apte à coopérer avec ledit deuxième orifice.According to an advantageous embodiment, the locking means comprise an abutment disposed at the upper end of the upper element, a second orifice entirely passing through the upper end of the upper element and disposed under said abutment, and a locking adapted to cooperate with said second orifice.

On comprend que ces étapes peuvent ne pas être exécutées dans l'ordre indiqué. Par exemple, la fixation de la toile peut être réalisée avant de fixer l'extrémité libre des câbles aux points de fixation du cadre.It is understood that these steps may not be executed in the indicated order. For example, the fastening of the fabric can be carried out before fixing the free end of the cables to the fixing points of the frame.

Meilleure manière de réaliser l'invention techniqueBest way to realize the technical invention

On a représenté sur les figures 2 à 13 un abri léger 1 comprenant un ensemble support 2, un élément de toiture 3 comportant un cadre 4 en forme de polygone et une toile 5 fixée par son bord périphérique extérieur sur le cadre 4 et destinée à être tendue entre ledit cadre 4 et l'ensemble support 2, ladite toile 2 est pourvue dans sa partie centrale d'un orifice dont le bord définit le bord périphérique intérieur de la toile 2. Cet abri léger 4 comporte en outre un collecteur d'eau pluviale 6.We have shown on Figures 2 to 13 a light shelter 1 comprising a support assembly 2, a roof element 3 comprising a frame 4 in the form of a polygon and a web 5 fixed by its outer peripheral edge on the frame 4 and intended to be stretched between said frame 4 and the support assembly 2, said fabric 2 is provided in its central part with an orifice whose edge defines the inner peripheral edge of the fabric 2. This lightweight shelter 4 further comprises a rainwater collector 6.

Conformément à l'invention, ledit élément support 2 comporte un mât central 7, des moyens de liaison 8 (voir la figure 9) montés coulissants sur ledit mât central 7 et agencés pour être verrouillés sur ledit mât central 7, une bride 9 montée coulissante sur ledit mât central 7 et agencée pour être fixée à l'extrémité supérieure dudit mât central 7, et une pluralité de câbles 10 dont l'une des extrémités est fixée sur ladite bride 9, l'autre étant destinée à être fixée sur le cadre 4. Ainsi, on comprend bien que cet élément support 2 comporte peu de pièces et est par conséquent facile et rapide à mettre en oeuvre.According to the invention, said support element 2 comprises a central mast 7, connecting means 8 (see FIG. figure 9 ) slidably mounted on said central mast 7 and arranged to be locked on said central mast 7, a flange 9 slidably mounted on said central mast 7 and arranged to be fixed to the upper end of said central mast 7, and a plurality of cables 10 one of whose ends is fixed on said flange 9, the other being intended to be fixed on the frame 4. Thus, it is well understood that this support element 2 has few parts and is therefore easy and quick to put in place. artwork.

Le mât central 7 est destiné à être fixé sur un massif (non représenté) par des moyens de fixation (non représentés) tels que des crosses de scellement ou tout autre moyen analogue procurant les mêmes effets tel que des chevilles chimiques ou auto-expansives par exemple.The central mast 7 is intended to be fixed on a solid mass (not shown) by fastening means (not shown) such as sealing butts or any other similar means providing the same effects such as chemical or self-expanding pins by example.

De plus, le mât central 7 est télescopique afin de limiter les dimensions des emballages et les coûts de transport de l'abri léger 1 avant montage. Pour cela, le mât central 7 comporte au moins un élément inférieur 71 fixé sur ledit massif et un élément supérieur 72 agencé pour coulisser à l'intérieur dudit élément inférieur 71 entre une "position rentrée" dans laquelle ledit élément supérieur 72 est disposé entièrement ou en majeure partie dans ledit élément inférieur 71 (voir la figure 2), et une "position sortie" dans laquelle ledit élément supérieur 72 est disposé en majeure partie hors dudit élément inférieur 71 (voir la figure 10). On comprend bien que, dans la "position sortie", il est nécessaire, pour bloquer les éléments inférieur et supérieur 71, 72 entre eux, que l'élément supérieur 72 est encore son extrémité basse dans l'extrémité haute dudit élément inférieur 71 (voir la figure 8). Pour ce blocage en "position sortie", l'élément support 2 comporte, en référence à la figure 8, des moyens de blocage comprenant au moins un organe de blocage 11 apte à coopérer avec un premier orifice 73 traversant entièrement l'extrémité basse de l'élément supérieur 72. Ledit organe de blocage 11 comprend de préférence deux viroles 111, 112 agencées pour être fixées autour de la jonction des éléments inférieur et supérieur 71, 72 et un goujon 113 solidaire d'une des viroles 111 et apte à coopérer simultanément avec ledit premier orifice 73 de l'élément supérieur 72 et un orifice 114 de l'autre virole 112. Dans la "position sortie", le goujon 113 vient en appui sur la face annulaire de l'extrémité haute de l'élément inférieur 71 du mât central 7. Cette "position sortie" est parfaitement sécurisée car, d'une part, les viroles 111, 112 bloquent les éléments inférieur et supérieur 71, 72 et ont une longueur suffisante pour éviter tout désengagement et, d'autre part, les câbles 10 de l'ensemble support 2 vont exercer sur ladite bride 9 et sur l'élément supérieur 72 un effort de traction vers le bas de sorte à maintenir le goujon 113 de l'organe de blocage 11 en appui sur la face annulaire de l'extrémité supérieure de l'élément inférieur 71 du mât central 7 et donc maintenir les éléments inférieur et supérieur 71, 72 verrouillés en position l'un par rapport à l'autre.In addition, the central mast 7 is telescopic in order to limit the dimensions of the packages and the transport costs of the light shelter 1 before assembly. For this purpose, the central mast 7 comprises at least one lower element 71 fixed on said solid mass and an upper element 72 arranged to slide inside said lower element 71 between a "retracted position" in which said upper element 72 is disposed entirely or for the most part in said lower element 71 (see figure 2 ), and an "output position" in which said upper member 72 is disposed largely out of said lower member 71 (see FIG. figure 10 ). It is well understood that, in the "outward position", it is necessary, to block the lower and upper elements 71, 72 between them, that the upper element 72 is still its lower end in the upper end of said lower element 71 (see FIG. figure 8 ). For this blocking in "outward position", the support element 2 comprises, with reference to the figure 8 , locking means comprising at least one locking member 11 adapted to cooperate with a first orifice 73 completely passing through the lower end of the upper member 72. Said locking member 11 preferably comprises two rings 111, 112 arranged to be fixed around the junction of the lower and upper elements 71, 72 and a pin 113 integral with one of the rings 111 and able to cooperate simultaneously with said first orifice 73 of the upper member 72 and an orifice 114 of the other ferrule 112 In the "outward position", the stud 113 bears on the annular face of the upper end of the lower element 71 of the central mast 7. This "extended position" is perfectly secure because, on the one hand, the ferrules 111, 112 block the lower and upper elements 71, 72 and have a length sufficient to prevent disengagement and, secondly, the cables 10 of the support assembly 2 will exert on said flange 9 and on the upper element 72 a downward pulling force so as to maintain the pin 113 of the locking member 11 bears against the annular face of the upper end of the lower element 71 of the central mast 7 and therefore maintain the lower and upper elements 71, 72 locked in position relative to each other.

Dans une variante de réalisation non représentée, le goujon 113 de l'organe de blocage 11 ne vient pas en appui sur la face annulaire de l'extrémité haute de l'élément inférieur 71 du mât central 7 mais coopèrent chacun avec des orifices réalisés dans l'extrémité haute de l'élément inférieur 71 dudit mât central 7. Toutefois, cette configuration est peu avantageuse car elle nécessite un positionnement angulaire de l'élément supérieur 72 par rapport à l'élément inférieur 71 lors de son montage.In an alternative embodiment not shown, the pin 113 of the locking member 11 does not rest on the annular face of the upper end of the lower member 71 of the central mast 7 but each cooperate with orifices made in the upper end of the lower element 71 of said central mast 7. However, this configuration is not advantageous because it requires a angular positioning of the upper member 72 relative to the lower member 71 during its assembly.

Dans une autre variante de réalisation non représentée, l'organe de blocage 11 pourra être remplacé, sans sortir du cadre de la présente invention, par au moins un moyen de verrouillage rapide du type à encliquetage solidaire de l'extrémité basse de l'élément supérieur 72 et apte soit à venir en appui sur la face annulaire de l'extrémité haute de l'élément inférieur 71 du mât central 7, soit à coopérer avec des orifices réalisés dans l'extrémité haute de l'élément inférieur 71 dudit mât central 7.In another variant of embodiment not shown, the locking member 11 may be replaced, without departing from the scope of the present invention, by at least one quick locking means snap type secured to the lower end of the element upper 72 and adapted either to bear against the annular face of the upper end of the lower element 71 of the central mast 7, or to cooperate with orifices made in the upper end of the lower element 71 of said central mast 7.

En outre, en référence aux figures 5 et 6, l'élément supérieur 72 est pourvu à son extrémité haute d'une butée 74 et d'un deuxième orifice 75 traversant entièrement l'extrémité haute de l'élément supérieur 72 et disposé sous ladite butée 74. Cette dernière est avantageusement un disque fermant l'élément supérieur 72 dont les dimensions sont supérieures à celles de la section horizontale dudit élément supérieur 72. La butée 74 et le deuxième orifice 75 forment, avec au moins un organe de verrouillage 12 de préférence du type broche apte à coopérer avec ledit deuxième orifice 75, des moyens de verrouillage permettant de bloquer en position la bride 9 à l'extrémité haute de l'élément supérieur 72.In addition, with reference to Figures 5 and 6 , the upper element 72 is provided at its upper end with a stop 74 and a second orifice 75 completely through the upper end of the upper element 72 and disposed under said stop 74. The latter is advantageously a closing disc the upper element 72 whose dimensions are greater than those of the horizontal section of said upper element 72. The abutment 74 and the second orifice 75 form, with at least one locking member 12 preferably of the spindle type adapted to cooperate with said second orifice 75, locking means for locking in position the flange 9 at the upper end of the upper element 72.

Par ailleurs, en référence aux figures 11 et 12, le mât central 7 est de préférence un tube creux raccordé en partie inférieure à un dispositif d'évacuation des eaux de pluie non représenté. De plus, ce mât central 7 comporte un orifice 76 apte à coopérer avec le collecteur d'eau pluviale 6 pour évacuer vers ledit dispositif d'évacuation des eaux de pluie reçues sur la toile 5 de l'élément de toiture 3.Moreover, with reference to Figures 11 and 12 , the central mast 7 is preferably a hollow tube connected in the lower part to a not shown rainwater drainage device. In addition, this central mast 7 has an orifice 76 adapted to cooperate with the rainwater collector 6 to discharge to said rainwater evacuation device received on the fabric 5 of the roof element 3.

Les moyens de liaison 8 sont en outre agencés pour recevoir le bord périphérique intérieur de la toile 5. Pour cela, ces moyens de liaison 8 sont analogues aux moyens de liaison décrits dans la demande de brevet européen EP 1 905 926 déposée au de la demanderesse.The connecting means 8 are furthermore arranged to to receive the inner peripheral edge of the fabric 5. For this, these connecting means 8 are similar to the connecting means described in the European patent application EP 1,905,926 filed at the plaintiff's.

Ainsi, en référence avec la figure 9, la toile 5 comporte le long de son bord périphérique intérieur un jonc 51, c'est-à-dire un bourrelet. Ce jonc 51 est formé par un anneau pris dans un pli de ladite toile 5, ledit anneau étant par exemple réalisé en corde naturelle ou synthétique.So, with reference to the figure 9 , the fabric 5 comprises along its inner peripheral edge a ring 51, that is to say a bead. This ring 51 is formed by a ring taken in a fold of said web 5, said ring being for example made of natural or synthetic rope.

Les moyens de liaison 8 comportent une cerce 81, c'est-à-dire une partie annulaire, destinée à recevoir sur sa face extérieure le jonc 51 de la toile 5. Cette cerce 81 est pourvue à son extrémité supérieure d'une butée 82 s'étendant radialement vers l'extérieur, fixée à la cerce 81 par exemple par soudage, et un anneau de blocage 83 qui, dans la position où la toile 5 est montée, est interposé entre le jonc 51 et la butée 82 assurant ainsi le blocage du jonc 51.The connecting means 8 comprise a hoop 81, that is to say an annular portion, intended to receive on its outer surface the rod 51 of the cloth 5. This hoop 81 is provided at its upper end with a stop 82 extending radially outwards, fixed to the hoop 81 for example by welding, and a locking ring 83 which, in the position where the fabric 5 is mounted, is interposed between the rod 51 and the stop 82 thus ensuring the locking of the ring 51.

Par ailleurs, les moyens de liaison 8 comportent également une virole 84 de préférence cylindrique permettant le coulissement desdits moyens de liaisons 8 le long du mât central 7 et des moyens de jonction 85 reliant la virole 84 à la cerce 81, ces moyens de jonction 85 étant par exemple sous forme d'une pluralité d'ailes radiales (Voir la figure 10).Furthermore, the connecting means 8 also comprise a ferrule 84, preferably cylindrical, for sliding said connecting means 8 along the central mast 7 and joining means 85 connecting the ferrule 84 to the core 81, these connecting means 85 being for example in the form of a plurality of radial wings (See figure 10 ).

La bride 9 est de préférence un élément tubulaire de type virole monté coulissant sur le mât central 7 jusqu'à une "position blocage", dans laquelle la bride 9 est bloquée à l'extrémité haute de l'élément supérieur 72 dudit mât central 7 entre la butée 74 et l'organe de verrouillage 121 disposé dans le deuxième orifice 75.The flange 9 is preferably a ferrule-type tubular element slidably mounted on the central mast 7 to a "locking position" in which the flange 9 is locked at the upper end of the upper element 72 of said central mast 7 between the stop 74 and the locking member 121 disposed in the second orifice 75.

Dans une variante de réalisation non représentée, l'organe de verrouillage 121 est remplacé par au moins un moyen de verrouillage rapide du type à encliquetage solidaire de la bride 9 et apte à coopérer avec le deuxième orifice 75 réalisé dans l'extrémité haute de l'élément supérieur dudit mât central 7. Toutefois, cette configuration est peu avantageuse car elle nécessite un positionnement angulaire de la bride 9 lors de son montage.In an alternative embodiment not shown, the locking member 121 is replaced by at least one rapid locking means of the latching type integral with the flange 9 and adapted to cooperate with the second orifice 75 formed in the upper end of the upper element of said central mast 7. However, this configuration is disadvantageous because it requires positioning angular of the flange 9 during its assembly.

Conformément à l'invention, l'abri léger 1 comporte également un élément de toiture 3 comportant un cadre 4 disposé autour du mât central 7 de l'ensemble support 2, constitué de longeron 41 assemblés les uns aux autres, ayant une forme globale de polygone régulier et étant suspendu par les câbles 10 de l'ensemble support 2 reliés uniquement à chacun des sommets dudit cadre 4 afin de limiter les porte-à-faux. Pour des raisons d'équilibre mécanique, le cadre 4 aura avantageusement un nombre pair de sommets au minimum égal à six.According to the invention, the light shelter 1 also comprises a roof element 3 comprising a frame 4 disposed around the central mast 7 of the support assembly 2, consisting of a spar 41 assembled to each other, having a global shape of regular polygon and being suspended by the cables 10 of the support assembly 2 connected only to each of the vertices of said frame 4 to limit the overhangs. For reasons of mechanical balance, the frame 4 will advantageously have an even number of vertices at least equal to six.

Par ailleurs, afin de diminuer les dimensions de la section des éléments profilés et donc leur poids et leur coût, les longerons 41, notamment ceux de grande longueur, comportent chacun de préférence un moyen de précontrainte non représentés permettant de mettre chaque longeron 41 en état de tension, ladite tension est opposée à celle qui sera exercée par la toile 5 lorsque cette dernière sera tendue.Moreover, in order to reduce the dimensions of the section of the profiled elements and therefore their weight and cost, the longitudinal members 41, especially those of great length, each preferably comprise a prestressing means not shown for putting each beam 41 in a state tension, said tension is opposite to that which will be exerted by the web 5 when the latter will be stretched.

En référence aux figures 2 à 13, la présente invention a également pour objet le procédé de montage dudit abri léger 1. Ce montage se déroule de la manière suivante.With reference to Figures 2 to 13 the present invention also relates to the mounting method of said light shelter 1. This assembly proceeds in the following manner.

La toile 5 est posée sur le sol de sorte que le massif devant recevoir le mât central 7 de l'ensemble support 2 apparaisse dans l'orifice de la toile 5.The fabric 5 is placed on the ground so that the mass to receive the central mast 7 of the support assembly 2 appears in the orifice of the fabric 5.

L'ensemble support 2 est érigé en mettant en place le mât central 7 sur le massif, au préalable les moyens de liaison 8 et la bride 9 sont montés coulissants sur ledit mât central 7, les câbles 59 étant avantageusement fixés à l'une de leurs extrémités à la bride 9.The support assembly 2 is erected by placing the central mast 7 on the solid mass, beforehand the connecting means 8 and the flange 9 are slidably mounted on said central mast 7, the cables 59 being advantageously fixed at one of their ends to the flange 9.

On notera que pour cette étape d'érection de l'ensemble support 2, il n'est pas nécessaire de recourir à une grue, car le mât central 7 est télescopique et comporte au moins un élément inférieur 71 fixé sur ledit massif et un élément supérieur 72 agencé pour coulisser à l'intérieur dudit élément inférieur 71.Note that for this erection stage of the support assembly 2, it is not necessary to resort to a crane, because the central mast 7 is telescopic and comprises at least one lower element 71 fixed on said solid mass and an element upper 72 arranged to slide inside said lower member 71.

L'étape suivante consiste à assembler et à mettre en place le cadre 4 autour dudit ensemble support 2, comme représenté sur la figure 3. Pour cette opération, on apporte les éléments du cadre 4 formés de longerons 41. Ces derniers sont posés sur le sol ou des tréteaux et le cadre 4 est monté sur place par fixation - par exemple par boulonnage - des extrémités de longerons 41 entre elles. Par ailleurs, au fur et à mesure de l'assemblage du cadre 4, un moyen de précontrainte pourra être mis en place sur chaque longeron 41 dudit cadre 4, notamment pour les cadres 4 de grandes dimensions.The next step is to assemble and set up the frame 4 around said support assembly 2, as shown in FIG. figure 3 . For this operation, it brings the frame elements 4 formed of longitudinal members 41. These are placed on the ground or trestles and the frame 4 is mounted on site by fixing - for example by bolting - the ends of longitudinal members 41 between them. Furthermore, as and when assembly of the frame 4, prestressing means may be placed on each spar 41 of said frame 4, especially for frames 4 large.

Comme représenté sur la figure 3, l'extrémité libre des câbles 10 est ensuite fixée sur le cadre 4.As shown on the figure 3 , the free end of the cables 10 is then fixed on the frame 4.

Comme représenté sur la figure 4, l'ensemble cadre 4-câbles 10-bride 9 est ensuite légèrement soulevé à l'aide d'un moyen de levage approprié telle qu'une grue dont le crochet est relié à ladite bride 9, de telle sorte qu'il soit maintenu à une hauteur suffisante pour permettre une mise en place aisée de la toile 5. La toile 5 est fixée de façon sensiblement étanche, sur le cadre 4 par tout moyen connu et notamment collage, soudage, clipsage ou par un dispositif de fixation semblable à celui décrit dans le brevet européen EP 0 277 073 délivré au nom de la demanderesse. Pour plus de détails concernant ce dernier mode de fixation de la toile 5, on se référera à ladite demande de brevet européen. A ce stade, la toile 5 n'est pas encore tendue.As shown on the figure 4 the frame assembly 4-cables 10-flange 9 is then slightly raised using a suitable lifting means such as a crane whose hook is connected to said flange 9, so that it is maintained at a height sufficient to allow easy placement of the fabric 5. The fabric 5 is fixed substantially sealingly on the frame 4 by any known means and in particular bonding, welding, clipping or by a fastening device similar to that described in the European patent EP 0 277 073 issued in the name of the plaintiff. For more details concerning this last method of fixing the fabric 5, reference will be made to said European patent application. At this point, the canvas 5 is not yet tense.

Ensuite, comme représenté sur les figures 5 et 6, l'ensemble cadre 4-toile 5-câbles 10-bride 9 est ensuite soulevé jusqu'à ce que la bride 9 soit en "position blocage" et vienne en contact avec la butée 74 de l'élément supérieur 72 du mât central 7. L'organe de verrouillage 12 est alors disposé dans le deuxième orifice 75 pour bloquer la bride 9 à l'extrémité haute de l'élément supérieur 72 dudit mât central 7.Then, as shown on Figures 5 and 6 the frame assembly 4-web 5-cables 10-flange 9 is then lifted until the flange 9 is in "locking position" and comes into contact with the stop 74 of the upper element 72 of the central mast 7 The locking member 12 is then arranged in the second orifice 75 to lock the flange 9 at the upper end of the upper member 72 of said central mast 7.

Comme représenté sur les figures 7 et 8, l'ensemble cadre 4-toile 5-câbles 10-bride 9-élément supérieur 72 est soulevé jusqu'à ce que l'élément supérieur 72 soit en "position sortie" et que son premier orifice 73 vienne au dessus de la face annulaire de l'extrémité haute de l'élément inférieur 71 du mât central 7. L'organe de blocage 11 est alors disposé de sorte que ses viroles 111, 112 soient disposées de part et d'autre de la zone de jonction des éléments inférieur et supérieur 71, 72 du mât central 7, et que son goujon 113 coopère simultanément avec ledit premier orifice 73 de l'élément supérieur 72 et l'orifice 114 de la virole 112 et soit en appui sur la face annulaire de l'extrémité haute de l'élément inférieur 71 du mât central 7.As shown on figures 7 and 8 , the assembly frame 4-canvas 5-cables 10-flange 9-upper member 72 is raised until the upper member 72 is in "extended position" and its first orifice 73 comes above the annular face the upper end of the lower element 71 of the central mast 7. The locking member 11 is then arranged so that its rings 111, 112 are disposed on either side of the junction zone of the lower elements and 71, 72 of the central mast 7, and that its pin 113 cooperates simultaneously with said first orifice 73 of the upper member 72 and the orifice 114 of the ferrule 112 and is supported on the annular face of the upper end of the lower element 71 of the central mast 7.

Comme représenté sur les figures 9 et 10, on fixe ensuite les moyens de liaison 8 sur le bord périphérique intérieur de la toile 5 en interposant l'anneau de blocage 83 entre le jonc 51 de la toile 5 et la butée 83 assurant ainsi le blocage du jonc 51. Il suffit ensuite de tirer les moyens de liaison 8 vers le bas jusqu'à obtenir la tension souhaitée de la toile 5. Ceci peut être réalisé simplement, comme représenté sur la figure 10, en solidarisant un tire-câble 13 à main par exemple du type TIRFOR (Marque déposée) sur l'extrémité basse de l'élément inférieur 71 du mât central 7 et en reliant les moyens de liaison 8 au tire-câble 13 par un câble 14.As shown on Figures 9 and 10 the connecting means 8 are then fixed on the inner peripheral edge of the fabric 5 by interposing the locking ring 83 between the ring 51 of the fabric 5 and the stop 83 thus ensuring the locking of the ring 51. It is then sufficient to pull the connecting means 8 downwards until the desired tension of the web 5 is obtained. This can be done simply, as shown in FIG. figure 10 , by fastening a cable puller 13 for example of the type TIRFOR (registered trademark) on the lower end of the lower element 71 of the central mast 7 and connecting the means of connection 8 to the cable puller 13 by a cable 14.

Une fois la toile 5 tendue correctement, les moyens de liaison 8 sont verrouillés en position sur l'élément inférieur 71 du mât central 7 à l'aide, par exemple d'un axe 15 traversant simultanément les moyens de liaison 8 et le mât central 7, comme représenté sur la figure 11.Once the fabric 5 is stretched correctly, the connecting means 8 are locked in position on the lower element 71 of the central mast 7 by means of, for example, an axis 15 traversing simultaneously the connecting means 8 and the central mast 7, as shown on the figure 11 .

Le montage de l'abri léger 1 est maintenant quasiment terminé. On peut alors, en référence à la figure 12, retirer le tire-câble 13 de l'ensemble support 2 et mettre en place le collecteur d'eau pluviale 6 sur le mât central 7 autour des moyens de liaison 8.The assembly of the light shelter 1 is now almost finished. We can then, with reference to the figure 12 , remove the cable pull 13 from the support assembly 2 and place the rainwater collector 6 on the central mast 7 around the connecting means 8.

L'abri léger 1 monté présente alors l'aspect illustré sur la figure 13.The light shelter 1 mounted then has the appearance illustrated on the figure 13 .

On comprend bien que les étapes précédemment décrites peuvent ne pas être exécutées dans l'ordre indiqué. Par exemple, la fixation de la toile 5 peut être réalisée avant de fixer l'extrémité libre des câbles 10 au cadre 4.It is understood that the previously described steps may not be executed in the order indicated. For example, the fixing of the fabric 5 can be performed before fixing the free end of the cables 10 to the frame 4.

De même, on comprend bien que ce montage pourra comporter une étape de réalisation d'un massif en béton avant d'ériger l'ensemble support 2.Similarly, it is clear that this assembly may include a step of producing a concrete block before erecting the support assembly 2.

On notera encore que ce montage comporte peu d'étapes et qu'il est particulièrement simple et rapide à mettre en oeuvre.It should be noted that this assembly has few steps and that it is particularly simple and quick to implement.
