La valise suivant l'invention et illustrée aux dessins, qui a la forme d'une parallélépipède rectangle, est du type qui comporte des moyens de roulement 1, agencés le long de son arête 2 de manière à pouvoir tourner librement autour d'un axe 3 parallèle à ladite arête, et une poignée 4 articulée autour d'un axe 5 parallèle à l'axe 3. Cette poignée est agencée pour permettre d'assurer le pivotement de la valise autour de l'axe 3 susdit afin que le contact de la valise avec le sol soit limité auxdits moyens de roulement 1 et pour permettre la traction de la valise afin que son déplacement s'effectue en la faisant rouler sur ces moyens 1. Les parois de la valise montrée aux figures 1 et 2 sont réalisées en un matériau souple et résistant aux chocs, aux perforations ainsi qu'à l'usure. La paroi 6 de la valise, qui correspond à une des deux grandes faces de cette dernière, est libre, le long des trois arêtes adjacents 7, 7' et 7", et constitue le couvercle 8 de ladite valise. Des moyens de fermeture, constitués par une fermeture à glissière 9, sont agencés le long de ces trois arêtes pour autoriser la fermeture et l'ouverture de la valise. La valise est, pour assurer sa résistance, ceinturée par un cadre 10 rigide et indéformable réalisé en matière plastique ou en métal. Ce cadre, qui est nervuré, pour renforcer sa résistance aux déformations, est fixé aux quatre parois adjacentes 11, 11', 11" et 11"' et s'étend de part er d'autre du plan qui est parallèle aux deux grandes faces 12 et 12' et qui est équidistant de ces dernières. Les moyens de roulement 1 et la poignée 4 sont associés au cadre 10 pour que leurs parties fixes soient supportées par ce cadre et immobilisées par rapport à ce dernier. La dimension du cadre 10, prise perpendiculairement aux faces 12 et 12' correspond environ au 1/5ème de la distance qui sépare ces dernières.The suitcase according to the invention and illustrated in the drawings, which has the shape of a rectangular parallelepiped, is of the type which includes rolling means 1, arranged along its edge 2 so as to be able to rotate freely around an axis 3 parallel to said edge, and a handle 4 articulated about an axis 5 parallel to the axis 3. This handle is arranged to allow the pivoting of the bag around the above axis 3 so that the contact of the suitcase with the ground is limited to said rolling means 1 and to allow traction of the suitcase so that its movement is effected by rolling it over these means 1. The walls of the suitcase shown in FIGS. 1 and 2 are made in a flexible material resistant to shocks, punctures and wear. The wall 6 of the bag, which corresponds to one of the two large faces of the latter, is free, along the three adjacent edges 7, 7 ′ and 7 ", and constitutes the cover 8 of said bag. Closure means, constituted by a zipper 9, are arranged along these three edges to authorize the closing and the opening of the bag. The bag is, to ensure its resistance, surrounded by a rigid and non-deformable frame 10 made of plastic material or This frame, which is ribbed, to reinforce its resistance to deformation, is fixed to the four adjacent walls 11, 11 ', 11 "and 11"' and extends on either side of the plane which is parallel to the two large faces 12 and 12 ′ and which is equidistant from the latter. The rolling means 1 and the handle 4 are associated with the frame 10 so that their fixed parts are supported by this frame and immobilized with respect to the latter. frame 10, socket perpendicular to the faces 12 and 12 'corresponds approximately to 1 / 5th of the distance between them.

Comme montré aux dessins, les moyens de roulement 1 sont agencés le long de la petite arête 2 de la grande face 12 de la valise qui est opposée au couvercle 8 de cette dernière, tandis que la poignée 4 est articulée sur la face 11 de la valise, autour de son axe 5 qui est situé soit dans le plan précité parallèle aux faces 12 et 12', soit dans le voisinage de ce plan.As shown in the drawings, the rolling means 1 are arranged along the small edge 2 of the large face 12 of the bag which is opposite to the cover 8 of the latter, while the handle 4 is articulated on the face 11 of the suitcase, around its axis 5 which is located either in the above-mentioned plane parallel to the faces 12 and 12 ', or in the vicinity of this plane.

La poignée 4 est agencée pour qu'elle puisse occuper deux positions extrêmes, une première position (représentée en traits pleins à la figure 1 et en traits interrompus à la figure 2) dans laquelle elle est perpendiculaire à la paroi 11 susdite et permet de faire pivoter la valise autour de l'axe 3 des moyens de roulement 1 et de tracter la valise en la faisant rouler sur ces derniers et une seconde position (montrée en traits interrompus à la figure 1 et en traits pleins à la figure 2) dans laquelle elle est rabattue, lorsqu'elle n'est pas utilisée, sur la dite paroi 11. Un ressort, non représenté, est associé à la poignée 4 pour faire passer celle-ci, d'une manière connue en soi et suivant la flèche 13, automatiquement de sa première à sa seconde position extrême quand aucun effort n'est exercé sur ladite poignée. La dimension de la poignée, prise perpendiculairement à son axe 3, étant importante, cette dernière permet de tracter facilement la valise, en position inclinée, sans risques de contact avec les jambes.The handle 4 is arranged so that it can occupy two extreme positions, a first position (shown in solid lines in Figure 1 and in broken lines in Figure 2) in which it is perpendicular to the wall 11 above and allows to do pivot the suitcase around the axis 3 of the rolling means 1 and pull the suitcase by rolling it on the latter and a second position (shown in broken lines in Figure 1 and in solid lines in Figure 2) in which it is folded down, when it is not used, on said wall 11. A spring, not shown, is associated with the handle 4 for passing the latter, in a manner known per se and according to arrow 13 , automatically from its first to its second extreme position when no force is exerted on said handle. The dimension of the handle, taken perpendicular to its axis 3, being important, the latter makes it possible to easily tow the suitcase, in an inclined position, without risk of contact with the legs.

Comme montré aux dessins, la valise comprend deux pieds 14, associés à la face 11" susdite et au cadre rigide 10, qui s'étendent perpendiculairement à cette face 11". La longueur de ces pieds 14 et leur position sont telles, lorsque la valise repose sur ces pieds et sur les moyens de roulement 1, qu'elle soit stable et que ses faces 12 et 12' soient sensiblement verticales.As shown in the drawings, the bag comprises two feet 14, associated with the face 11 "above and with the rigid frame 10, which extend perpendicular to this face 11". The length of these feet 14 and their position are such, when the case rests on these feet and on the rolling means 1, that it is stable and that its faces 12 and 12 'are substantially vertical.

Le cadre 10 est agencé à l'intérieur de la valise et est recouvert d'une bande de tissu 15. La valise comprend, comme montré aux dessins, deux plaques 16 et 17, planes et rigides, réalisées en matière plastique, qui sont disposées à l'intérieur de la valise et fixées, en 18, au cadre 10, entre celui-ci et respectivement les parois 11 et 11" de la valise. La surface de ces plaques 16 et 17, disposées à l'intérieur de la valise, correspond à une partie importante de la surface des faces 11 et 11". Les moyens de roulement 1 et les pieds 14 sont fixés respectivement, en 19 et en 20, à la plaque 17, à travers la paroi 11", tandis que le support 21 de la poignée 4 est fixé au cadre 10 et à la plaque 16, à travers la paroi 11 de la valise. Comme montré aux dessins, la valise comprend avantageusement une plaque plane et rigide 22 fixée, à l'intérieur de la valise, à la grande face 12 précitée, à proximité de la plaque 17 susdite. Les moyens de roulement 1, qui sont fixés, en 20, à cette plaque 17, sont également fixés, en 23, à la plaque 22, à travers ladite paroi correspondant à la grande face 12 de la valise. Dans la forme de réalisation illustrée à la figure 1, les plaques 17 et 22 sont indépendantes l'une de l'autre, tandis que dans la forme de réalisation illustrée à la figure 2, ces plaques 17 et 22 sont réalisées en une seule pièce en forme d'équerre.The frame 10 is arranged inside the suitcase and is covered with a strip of fabric 15. The suitcase comprises, as shown in the drawings, two plates 16 and 17, flat and rigid, made of plastic, which are arranged inside the bag and fixed, in 18, to the frame 10, between the latter and the walls 11 and 11 "of the bag, respectively. The surface of these plates 16 and 17, arranged inside the suitcase, corresponds to a large part of the surface of the faces 11 and 11 ". The rolling means 1 and the feet 14 are fixed respectively, in 19 and 20, to the plate 17, through the wall 11 ", while the support 21 of the handle 4 is fixed to the frame 10 and to the plate 16 , through the wall 11 of the suitcase As shown in the drawings, the suitcase advantageously comprises a flat and rigid plate 22 fixed, inside the suitcase, to the aforementioned large face 12, near the aforementioned plate 17. The rolling means 1, which are fixed, at 20, to this plate 17, are also fixed, at 23, to the plate 22, through said wall corresponding to the large face 12 of the suitcase. in Figure 1, the plates 17 and 22 are independent of each other, while in the embodiment illustrated in Figure 2, these plates 17 and 22 are made in one piece in the form of a square.

Pour que le poids de la valise soit compensé lorsque celle-ci est tractée et qu'elle repose donc sur ses moyens de roulement 1, l'axe 5 de la poignée 4 est situé soit dans le plan parallèle à la face 12 précitée et qui passe par le bord 24 du cadre 10 le plus proche du couvercle 8 de la valise, soit à proximité de ce plan.So that the weight of the bag is compensated when it is towed and therefore rests on its rolling means 1, the axis 5 of the handle 4 is located either in the plane parallel to the face 12 above and which passes through the edge 24 of the frame 10 closest to the cover 8 of the suitcase, that is to say near this plane.

Les moyens de roulement 1 susdits sont constitués par deux ou trois roulettes 25 en fonction de la longueur de l'arête 2 précitée. Ces roulettes 24 sont, comme montré à la figure 1, montées chacune dans un support 26. Ces supports sont alignés et fixés aux plaques 17 et 22 susdites pour que les axes 3 des roulettes 25 soient confondus. Dans la forme de réalisation illustrée à la figure 2, les roulettes 25 sont agencées dans un support commun 27 pour que leurs axes 3 soient confondus, celui- ci étant associé au cadre 10, par l'intermédiaire de la pièce en équerre formée par les plaques 17 et 22 précitées.The above-mentioned rolling means 1 are constituted by two or three rollers 25 depending on the length of the aforementioned edge 2. These rollers 24 are, as shown in FIG. 1, each mounted in a support 26. These supports are aligned and fixed to the abovementioned plates 17 and 22 so that the axes 3 of the rollers 25 are combined. In the embodiment illustrated in FIG. 2, the rollers 25 are arranged in a common support 27 so that their axes 3 are coincident, this being associated with the frame 10, by means of the square piece formed by the plates 17 and 22 above.

Chacune des parties cylindriques raccordant les parois 11, 11', 11" et 11"' de la valise sont, comme montré aux dessins, doublées intérieurement par des pièces de renfort préformées et rigides 28 qui sont immobilisées entre ces parois et le cadre 10.Each of the cylindrical parts connecting the walls 11, 11 ', 11 "and 11"' of the bag are, as shown in the drawings, lined internally by preformed and rigid reinforcing pieces 28 which are immobilized between these walls and the frame 10.

La valise suivant l'invention comprend avantageusement une poignée 29 qui est fixée sur le cadre 10, parallèlement au côté 30 de ce dernier, à travers la paroi 11' de la valise, la paroi 11" de cette dernière étant renforcée intérieurement par une plaque semi rigide 31 qui la double sur pratiquement toute sa surface. Cette plaque 31, qui est immobilisée entre le cadre 10 et la paroi 11", peut former, avec les pièces de renfort 28 susdites situées à ses extrémités, une seule pièce.The suitcase according to the invention advantageously comprises a handle 29 which is fixed to the frame 10, parallel to the side 30 of the latter, through the wall 11 'of the suitcase, the wall 11 "of the latter being reinforced internally by a plate semi-rigid 31 which doubles it over practically its entire surface. This plate 31, which is immobilized between the frame 10 and the wall 11 ", can form, with the abovementioned reinforcing pieces 28 situated at its ends, a single piece.

Dans la forme de réalisation de la valise suivant l'invention, qui est illustrée aux figures 3 et 4, la poignée 4 est encastrée dans la valise, de manière à affleurer la face 11 de cette dernière sur laquelle elle est articulée. La poignée 4 est logée dans une coquille préformée rigide 32 appliquée, à l'extérieur de la valise, sur ladite face. Cette dernière et la face 12 présentent une découpe 33 agencée pour permettre le passage, à l'intérieur de la valise, de la partie en creux 34 de la coquille 32 dans laquelle se loge la poignée 4 lorsqu'elle n'est pas utilisée. Une plaque rigide 35, qui épouse les formes de la coquille 32 et dans laquelle est pratiquée une découpe 36 correspondant à la découpe précitée 33 réalisée dans la face 11, est disposée à l'intérieur de la valise de manière à ce qu'elle s'applique sur la coquille 32, de part et d'autre de la partie en creux 34 susdite, en pinçant les parois de la valise correspondant aux face 11 et 12 précitées. Le support 21 de l'articulation de la poignée 4 autour de l'axe 5 précité, est constitué par une pièce métallique indéformable 41 et comprenant deux pattes 37 dans lesquelles est disposé l'arbre 40 autour duquel tourne la poignée 4. Cette dernière comporte deux butées 42 qui sont agencées pour venir prendre appui sur la face 43 de la pièce 41 susdite. De sorte que ladite poignée 4 est fermement immobilisée, lorsqu'elle est utilisée, dans une position parallèle aux faces 12 et 12' de la valise. Cette pièce 41 est fixée directement au cadre 10 tandis que la plaque 35 et la coquille 32 sont fixées, en 38, au cadre 10 susdit ainsi qu'aux faces 11 et 12 de la valise. Des moyens sont prévus pour maintenir automatiquement la poignée 4, à l'intérieur de la coquille 32, lorsqu' elle n'est pas utilisée et sont par exemple constitués par un ressort 39 associé à l'arbre 40 de la poignée et coaxial à ce dernier.
