Abstract

The device comprises four hollow composite material tubes (1/1,1/2,1/3,1/4), two wooden drilled and machined junction pieces (1,2), two drilled and machined wooden bars (3/1,3/2) connected by a resilient system (4,5) and a flexible sheet (6). The junction pieces and the hollow tubes are glued (7) together and the resilient system slides inside the hollow tubes.

Description

- 1La présente invention concerne un dispositif léger, pliable, d'un seul tenant, peu encombrant, d'un montage/démontage évident permettant de maintenir, par lui-même, tendu et en position debout un support souple. - 1The present invention relates to a light, foldable device, in one piece, compact, of an obvious assembly / disassembly allowing to maintain, by itself, taut and in the upright position a flexible support.

Couramment, les supports souples sont tendus et maintenus en position debout grâce aux deux principes suivants : - dispositif léger composé de plusieurs pièces indépendantes (avec risques de perte des composants et montage peu pratique). Commonly, flexible supports are stretched and kept in an upright position thanks to the following two principles: - lightweight device made up of several independent parts (with risk of loss of components and impractical mounting).

- dispositif lourd, d'un seul tenant, à enrouleur, ne permettant pas une interchangeabilité du support souple par l'utilisateur sans intervention du fabricant. - heavy device, in one piece, with reel, not allowing interchangeability of the flexible support by the user without intervention by the manufacturer.

Le dispositif selon l'invention permet de remédier aux inconvénients des dispositifs décrits ci-dessus. Il se distingue, en effet, par les caractéristiques suivantes : - sa grande simplicité - sa facilité d'installation grâce aux élastiques restant invisibles, reliant tous les composants et permettant ainsi un montage/démontage rapide et évident du dispositif sans risque de perte des composants. The device according to the invention overcomes the drawbacks of the devices described above. It is distinguished, in fact, by the following characteristics: - its great simplicity - its ease of installation thanks to the elastic bands remaining invisible, connecting all the components and thus allowing rapid and obvious assembly / disassembly of the device without risk of loss of the components .

- La possibilité de changer instantanément le support souple par l'utilisateur et de l'utiliser en recto seul ou en recto/verso directement. - The possibility of instantly changing the flexible support by the user and using it on the front only or on the front / back directly.

De plus, le dispositif est constitué de matériaux apportant une utilisation fonctionnelle. In addition, the device is made of materials providing functional use.

Les modes particuliers de réalisation sont : - des tubes creux en matériaux composites, fibre de verre et résine - des pièces de jonction en bois usiné - un système d'élastiques - une feuille souple. The particular embodiments are: - hollow tubes made of composite materials, fiberglass and resin - junction pieces in machined wood - a system of elastics - a flexible sheet.

Le dessin annexé illustre l'invention. The accompanying drawing illustrates the invention.

La figure 1 représente le dispositif de l'invention En référence à ce dessin, le dispositif comporte : - 4 tubes creux en matériaux composites (1/1, 1/2, 1/3,1/4) - 1 pièce de jonction usinée bois, percée un axe (1) (nommée olive ) - 1 pièce de jonction usinée bois, percée trois axes (2) (nommée boule ) - 1 élastique (4) traversant de part en part 2 tubes creux (1/1,1/2) et la pièce de jonction (1) olive ) suivant un axe, circulant librement et noué aux extrémités, contraignant ces 2 tubes à une tenue verticale pré-établie dès qu'il se trouvent réunis dans la pièce de jonction (1) olive . FIG. 1 represents the device of the invention With reference to this drawing, the device comprises: - 4 hollow tubes made of composite materials (1/1, 1/2, 1 / 3,1 / 4) - 1 machined junction piece wood, pierced with an axis (1) (named olive) - 1 machined wood connecting piece, pierced with three axes (2) (named ball) - 1 elastic band (4) passing right through 2 hollow tubes (1 / 1.1 / 2) and the connecting piece (1) olive) along an axis, circulating freely and knotted at the ends, forcing these 2 tubes to a pre-established vertical holding as soon as they are joined in the connecting piece (1) olive.

- 1 élastique (5) traversant de part en part : 1 barre bois horizontal (3/1), 1 tube creux (1/3), la boule (2), 1 tube creux (1/4), noué aux extrémités. - 1 elastic (5) passing right through: 1 horizontal wooden bar (3/1), 1 hollow tube (1/3), the ball (2), 1 hollow tube (1/4), knotted at the ends.

- 1 feuille souple (6) collée et agrafée au bas de la barre (3/1) d'un côté et de la barre (3/2) de l'autre, de la largeur de l'écartement des tubes (1/3-1/4) maintient parallèlement les barres de bois (3/1) et (3/2) en constituant un socle obligeant l'ensemble à une tenue verticale et stable. - 1 flexible sheet (6) glued and stapled to the bottom of the bar (3/1) on one side and of the bar (3/2) on the other, the width of the spacing of the tubes (1 / 3-1 / 4) keeps the wooden bars (3/1) and (3/2) in parallel by constituting a base forcing the assembly to a vertical and stable hold.

- Les tubes (1/3 et 1/4), les barres (3/1 et 3/2), se trouvent contraint de se maintenir dans les axes définis par la boule de jonction (2) et dans les trous aménagés dans les barres (3/1-3/2). - The tubes (1/3 and 1/4), the bars (3/1 and 3/2), are forced to remain in the axes defined by the junction ball (2) and in the holes provided in the bars (3 / 1-3 / 2).

- 2 assemblages par collage haute résistance (7) du tube creux en matériaux composites (1/2), à l'olive (1) à une extrémité et à la boule (2) pour l'autre extrémité, conduisant automatiquement au bon positionnement de l'ensemble des composants du dispositif lors du montage.- 2 assemblies by high resistance bonding (7) of the hollow tube in composite materials (1/2), with the olive (1) at one end and the ball (2) for the other end, automatically leading to the correct positioning of all device components during assembly.
