Description

Domaine TechniqueTechnical area

L'invention concerne un sac à dos perfectionné, plus précisément un sac à dos muni d'un dispositif permettant le réglage de la hauteur des bretelles. De tels sacs à dos permettent le transport de charges soit dans un contenant fermé (sac à dos d'alpinisme ou de camping) soit dans un contenant ouvert, au moins en partie, par exemple pour le transport de charges, telles que celui des jeunes enfants dans des sacs appelés communément porte-enfant, voire des claies de portage.The invention relates to an improved backpack, more specifically a backpack provided with a device for adjusting the height of the shoulder straps. Such backpacks allow the transport of loads either in a closed container (mountaineering or camping backpack) or in an open container, at least in part, for example for the transport of loads, such as that of young people children in bags commonly known as child carriers, or even baby carriers.

Techniques antérieuresPrevious techniques

Comme on le sait, un sac à dos comprend d'une part, un sac proprement dit, destiné à recevoir la charge, présentant un dos généralement thermoformé et renforcé par une armature, et d'autre part, un harnais de portage solidaire de ce dos constitué essentiellement de deux bretelles et d'une ceinture.As is known, a backpack comprises on the one hand, a bag proper, intended to receive the load, having a generally thermoformed back and reinforced by a frame, and on the other hand, a carrying harness integral with this back consisting essentially of two straps and a belt.

De nombreux sacs à dos présentent deux bretelles réglables en longueur mais pas en hauteur, les points d'ancrage des bretelles étant positionnés de manière symétrique en haut et en bas du dos. Un tel système ne tient pas compte de la variation de la morphologie du dos d'un porteur à l'autre (voir figure 1).Many backpacks have two adjustable straps in length but not in height, the anchor points of the straps being positioned symmetrically at the top and bottom of the back. Such a system does not take into account the variation in the morphology of the back from one wearer to another (see Figure 1).

Face à ce problème, il est apparu nécessaire de pouvoir régler la hauteur des bretelles.Faced with this problem, it appeared necessary to be able to adjust the height of the shoulder straps.

Une solution consiste à ménager, sur le haut du dos, des passants parallèles cousus, au travers desquels on passe le haut de la bretelle à la hauteur choisie par le porteur. Cette disposition n'est pas satisfaisante puisque la bretelle ainsi réglée ayant une longueur constante, se trouve être trop longue pour les petits individus et trop courte pour les grands. En outre, le réglage est imprécis (voir figure 2).One solution is to provide, on the upper back, sewn parallel loops, through which the top of the strap is passed at the height chosen by the wearer. This arrangement is not satisfactory since the strap thus adjusted having a constant length, is found to be too long for small individuals and too short for large ones. In addition, the setting is imprecise (see Figure 2).

Dans le document FR-A-2 637 785, le Demandeur a proposé un sac à dos muni de deux bretelles reliées chacune à un étrier destiné à coopérer avec les bords latéraux de deux sangles cousues sur le haut du dos. Ce type de système, outre l'inconfort engendré par la présence des deux étriers dans le dos, ne permet pas au porteur de régler la hauteur des bretelles simultanément, ce qui entraîne un déséquilibre de la charge du sac. De plus, les étriers risquent de s'ouvrir à force de secousses et de vibrations lors du portage.In document FR-A-2 637 785, the Applicant has proposed a backpack provided with two straps each connected to a stirrup intended to cooperate with the lateral edges of two straps sewn on the upper back. This type of system, in addition to the discomfort caused by the presence of the two stirrups in the back, does not allow the wearer to adjust the height of the shoulder straps simultaneously, which leads to an imbalance in the load of the bag. In addition, the stirrups may open due to jolts and vibrations during carrying.

Le problème était donc de définir un système de réglage de bretelles précis, simultané et adaptable en fonction de la morphologie du dos du porteur.The problem was therefore to define a precise, simultaneous and adaptable strap adjustment system based on the morphology of the wearer's back.

Exposé de l'inventionStatement of the invention

L'invention vise un système de réglage des bretelles d'un sac à dos alliant respect du confort et de la morphologie du dos du porteur.The invention relates to a system for adjusting the straps of a backpack combining respect for the comfort and morphology of the wearer's back.

Le sac à dos selon l'invention comprend :

  • . un sac proprement dit,
  • . un dos solidaire du sac renforcé par une armature en forme de U inversé, dont les deux branches rigides cintrées sont fixées au dos, respectivement au sommet par la portion de raccordement des deux branches du U, et au bas par l'extrémité des deux branches ;
  • . un harnais de portage constitué de deux bretelles et d'une ceinture fixée au dos ;
caractérisé:
  • en ce que la face apparente extérieure du dos comporte deux bandes d'accrochage disposées en regard des deux branches de l'armature ;
  • en ce que l'extrémité supérieure des deux bretelles est reliée à une pièce de liaison apte à coulisser le long des deux branches cintrées, et dont la face en regard du dos comporte deux bandes d'accrochage disposées en regard des deux bandes d'accrochage fixées au dos pour coopérer avec celles-ci.
The backpack according to the invention comprises:
  • . a bag itself,
  • . a back secured to the bag reinforced by an inverted U-shaped frame, the two curved rigid branches of which are fixed to the back, respectively at the top by the connection portion of the two branches of the U, and at the bottom by the end of the two branches ;
  • . a carrying harness consisting of two shoulder straps and a belt attached to the back;
characterized:
  • in that the visible external face of the back comprises two fastening strips arranged opposite the two branches of the frame;
  • in that the upper end of the two straps is connected to a connecting piece capable of sliding along the two curved branches, and the facing face of the back comprises two fastening strips arranged opposite the two fastening strips attached to the back to cooperate with them.

En d'autres termes, le dos du sac présente deux bandes d'accrochage mâles parallèles, cousues à hauteur des deux branches de l'armature rigide, destinées à coopérer avec deux bandes d'accrochage femelles disposées sur une pièce de liaison reliée à l'extrémité de deux bretelles, la pièce de liaison étant mobile le long des branches de l'armature.In other words, the back of the bag has two parallel male fastening strips, sewn at the height of the two branches of the rigid frame, intended to cooperate with two female fastening strips arranged on a connecting piece connected to the end of two straps, the connecting piece being movable along the branches of the frame.

Pour régler la hauteur des deux bretelles de façon simultanée, il suffit de désolidariser la pièce de liaison du dos du sac et de la faire coulisser le long des armatures jusqu'à la position désirée.To adjust the height of the two shoulder straps simultaneously, simply separate the connecting piece from the back of the bag and slide it along the frames to the desired position.

Pour permettre un réglage précis, les bandes d'accrochages sont cousues de façon continue sur le dos du sac. Ainsi, le porteur peut faire varier la hauteur de la pièce de liaison et par conséquent celle des bretelles, à sa guise et de manière précise.To allow precise adjustment, the hanging strips are sewn continuously on the back of the bag. Thus, the wearer can vary the height of the connecting piece and therefore that of the straps, as he pleases and precisely.

Autrement dit, la hauteur de la pièce de liaison sera réglée en fonction de la taille du porteur. Plus le porteur sera petit, et plus la pièce de liaison sera positionnée loin de l'extrémité supérieure de l'armature. A l'inverse, plus le porteur sera de grande taille, et plus la pièce de liaison sera positionnée près de l'extrémité supérieure de ladite armature.In other words, the height of the connecting piece will be adjusted according to the size of the wearer. The smaller the carrier, the more the connecting piece will be positioned far from the upper end of the frame. Conversely, the larger the carrier, the more the connecting piece will be positioned near the upper end of said frame.

Etant fixées symétriquement sur la pièce de liaison, les deux bretelles se trouvent être toujours à la même hauteur, et ce, quelle que soit la position de la pièce de liaison. Cette caractéristique permet de ne pas déséquilibrer la répartition de la charge.Being symmetrically fixed on the connecting piece, the two straps happen to be always at the same height, regardless of the position of the connecting piece. This characteristic makes it possible not to unbalance the distribution of the load.

Avantageusement, les bandes d'accrochage sont du type "fermeture par contact velours et crochet".Advantageously, the fastening strips are of the "velvet and hook contact closure" type.

Selon une autre caractéristique de l'invention, la pièce de liaison est formée de deux plaques rigides reliées par leur extrémité latérale pour enserrer les deux branches rigides. Ces deux plaques peuvent être cousues, voire en une pièce injectée.According to another characteristic of the invention, the connecting piece is formed of two rigid plates connected by their lateral end to enclose the two rigid branches. These two plates can be sewn, or even in an injected part.

En d'autres termes, la pièce de liaison présente une conformation telle qu'elle puisse coulisser le long des branches cintrées de l'armature.In other words, the connecting piece has a conformation such that it can slide along the curved branches of the frame.

Pour que les bandes d'accrochage disposées à la fois sur la pièce de liaison et sur le dos du sac puissent exactement coopérer sans nécessiter d'ajustement latéral, les deux plaques ont une largeur légèrement supérieure à l'intervalle séparant les deux branches de l'armature. Les extrémités latérales des deux plaques sont cousues l'une à l'autre de façon à enserrer les deux branches de l'armature tout en permettant un coulissement de la pièce de liaison le long de celles-ci.So that the hanging strips arranged both on the connecting piece and on the back of the bag can cooperate exactly without requiring lateral adjustment, the two plates have a width slightly greater than the interval separating the two branches of the frame. The lateral ends of the two plates are sewn to each other so as to enclose the two branches of the frame while allowing sliding of the connecting piece along these.

Avantageusement, la plaque extérieure de la pièce de liaison comporte un élément compressible de confort destiné à venir au contact du dos du porteur, l'extrémité supérieure des bretelles étant reliée à hauteur des branches, au sommet de cette pièce compressible.Advantageously, the outer plate of the connecting piece comprises a compressible comfort element intended to come into contact with the back of the wearer, the upper end of the straps being connected at the height of the branches, at the top of this compressible piece.

La présence d'un élément de confort disposé sur la plaque extérieure de la pièce de liaison, permet d'amortir les chocs, notamment les secousses au niveau du dos du porteur. En outre, cette pièce permet d'éviter le contact douloureux entre le dos du porteur et les branches de l'armature.The presence of a comfort element arranged on the outer plate of the connecting piece, makes it possible to absorb shocks, in particular the tremors at the level of the back of the wearer. In addition, this part avoids painful contact between the back of the wearer and the arms of the frame.

Comme déjà dit, les bretelles sont fixées par leur extrémité supérieure au sommet de cette pièce compressible au regard de chacune des deux branches de l'armature.As already said, the straps are fixed by their upper end to the top of this compressible part with regard to each of the two branches of the frame.

Avantageusement, la face externe de chaque bretelle présente une sangle réglable reliée au sommet du dos.Advantageously, the external face of each strap has an adjustable strap connected to the top of the back.

Cette sangle permet de plaquer le haut du sac au niveau du dos du porteur et ainsi de mieux répartir la charge.This strap allows you to flatten the top of the bag at the back of the wearer and thus better distribute the load.

La manière dont l'invention peut être réalisée et les avantages qui en découlent ressortiront mieux de l'exemple de réalisation qui suit, à l'appui des figures annexées.The manner in which the invention can be implemented and the advantages which result therefrom will emerge more clearly from the embodiment which follows, with the support of the appended figures.

Manière de réaliser l'inventionWay of realizing the invention

L'invention vise un sac à dos muni d'un système de réglage de bretelles apte à respecter la morphologie du dos et le confort du porteur.The invention relates to a backpack provided with a strap adjustment system capable of respecting the morphology of the back and the comfort of the wearer.

Sur la figure 2, on a représenté un sac à dos tel qu'il est connu dans l'art antérieur.In Figure 2, there is shown a backpack as it is known in the prior art.

Ce sac à dos désigné par la référence (1), est muni d'un sac proprement dit (2) destiné à recevoir la charge, et d'un dos (3) accolé à ce sac et le plus souvent thermoformé. Le dos (3) est muni d'un harnais de portage (4) comprenant deux bretelles (5, 6) et une ceinture (7). Des passants parallèles (8) sont cousus sur le haut du dos, permettant ainsi le passage des bretelles (5, 6) dans un ou plusieurs passants (8), de manière à régler la hauteur desdites bretelles (5, 6). La ceinture (7) montrée sur les figures 1 et 2, est cousue au bas du dos du sac (3).This backpack designated by the reference (1), is provided with a bag proper (2) intended to receive the load, and with a back (3) attached to this bag and most often thermoformed. The back (3) is provided with a carrying harness (4) comprising two straps (5, 6) and a belt (7). Parallel loops (8) are sewn on the upper back, thus allowing the passage of the straps (5, 6) in one or more loops (8), so as to adjust the height of said straps (5, 6). The belt (7) shown in Figures 1 and 2 is sewn at the bottom of the back of the bag (3).

Le sac à dos (1) conforme à l'invention représenté en perspective arrière sur la figure 3, comporte un dos (3) solidaire du sac (2). En outre, ce dos (3) est renforcé par une armature (A) en forme de U inversé présentant deux branches rigides (9, 10), réunies par une portion de raccordement (11). Cette armature rigide (A) est fixée au sommet du dos (3) par la portion de raccordement (11) des deux branches (9, 10). Plus exactement, cette portion de raccordement (11) est introduite dans une poche (12) prévue à cet effet au sommet du dos (3). L'armature (A) est fixée en bas du dos (3) par l'extrémité (13, 14) des branches (9, 10).The backpack (1) according to the invention shown in rear perspective in Figure 3, has a back (3) integral with the bag (2). In addition, this back (3) is reinforced by a frame (A) in the shape of an inverted U having two rigid branches (9, 10), joined by a connection portion (11). This rigid frame (A) is fixed to the top of the back (3) by the connection portion (11) of the two branches (9, 10). More precisely, this connection portion (11) is introduced into a pocket (12) provided for this purpose at the top of the back (3). The frame (A) is fixed at the bottom of the back (3) by the end (13, 14) of the branches (9, 10).

Selon une caractéristique essentielle de l'invention, le dos (3) comporte sur sa face apparente extérieure (16), deux bandes d'accrochage (17, 18) disposées en regard des deux branches (9, 10) de l'armature (A). Ces deux bandes d'accrochage (17, 18) sont cousues sur la face apparente extérieure (16) du dos (3), et ce, sur une portion égale à la hauteur des branches (9, 10) de l'armature (A).According to an essential characteristic of the invention, the back (3) comprises on its external visible face (16), two fastening strips (17, 18) arranged opposite the two branches (9, 10) of the frame ( AT). These two attachment bands (17, 18) are sewn on the visible external face (16) of the back (3), and this, on a portion equal to the height of the branches (9, 10) of the frame (A ).

Avantageusement, tel qu'il est montré sur la figure 4, les bandes d'accrochage (17, 18) sont cousues sur les deux tiers de la hauteur du dos (3).Advantageously, as shown in FIG. 4, the fastening strips (17, 18) are sewn over two thirds of the height of the back (3).

Par ailleurs, le sac à dos conforme à l'invention comporte un harnais de portage muni d'une ceinture (19) et de deux bretelles (20, 21) reliées par leur extrémité supérieure (22, 23) à une pièce de liaison (24).Furthermore, the backpack according to the invention comprises a carrying harness provided with a belt (19) and two shoulder straps (20, 21) connected by their upper end (22, 23) to a connecting piece ( 24).

Cette pièce de liaison (24) est destinée à coulisser le long des branches cintrées (9, 10) de l'armature (A). Cette pièce de liaison (24), comme le montre la figure 6, est munie de deux bandes d'accrochage (25, 26) disposées en regard des deux bandes d'accrochage (17, 18) cousues au dos (3) du sac (2), et ce, pour pouvoir coopérer. Autrement dit, la position de ces bandes d'accrochage l'une en regard de l'autre, permet de fixer dans une position déterminée la pièce de liaison.This connecting piece (24) is intended to slide along the curved branches (9, 10) of the frame (A). This connecting piece (24), as shown in Figure 6, is provided with two hooking bands (25, 26) arranged opposite the two hooking bands (17, 18) sewn on the back (3) of the bag (2), in order to be able to cooperate. In other words, the position of these fastening strips one opposite the other, makes it possible to fix the connecting piece in a determined position.

Avantageusement, ces bandes d'accrochage sont du type "fermeture par contact velours et crochet".Advantageously, these fastening strips are of the "velvet and hook contact closure" type.

Comme il est montré sur la figure 6, la pièce de liaison (24) est formée de deux plaques rigides (27, 28) reliées entre elles par leur extrémité latérale (29, 30, 31, 32), de façon à enserrer les deux branches rigides (9, 10) de l'armature (A). La largeur (L) des deux plaques rigides (27, 28) formant la pièce de liaison (24), est légèrement supérieure à la distance (D) séparant les deux branches (9,10) de l'armature (A) de façon à pouvoir enserrer lesdites branches.As shown in Figure 6, the connecting piece (24) is formed of two rigid plates (27, 28) connected together by their lateral end (29, 30, 31, 32), so as to enclose the two rigid branches (9, 10) of the frame (A). The width (L) of the two rigid plates (27, 28) forming the connecting piece (24), is slightly greater than the distance (D) separating the two branches (9,10) of the frame (A) so to be able to grip said branches.

Chacune des extrémités latérales (29, 30) et (31, 32) des plaques rigides (27, 28) sont cousues l'une à l'autre. La couture est réalisée à une distance suffisante du bord extérieur des branches (9, 10) pour permettre le bon coulissement de la pièce de liaison le long des armatures.Each of the lateral ends (29, 30) and (31, 32) of the rigid plates (27, 28) are sewn to each other. The seam is made at a sufficient distance from the outer edge of the branches (9, 10) to allow the sliding of the connecting piece along the frames.

En pratique, la couture est effectuée à un centimètre des bords extérieurs de l'armature (A).In practice, the seam is made at one centimeter from the outer edges of the frame (A).

Selon une autre caractéristique de l'invention, la plaque extérieure (24) comporte un élément compressible (31) de confort, destiné à venir au contact du dos du porteur. Cet élément compressible (31) est relié à l'extrémité supérieure (22, 23) des bretelles (20, 21) en son sommet. Les bretelles (20, 21) sont ainsi cousues à hauteur des branches (9, 10) de l'armature (A).According to another characteristic of the invention, the outer plate (24) comprises a compressible comfort element (31), intended to come into contact with the back of the wearer. This compressible element (31) is connected to the upper end (22, 23) of the straps (20, 21) at its top. The straps (20, 21) are thus sewn at the height of the branches (9, 10) of the frame (A).

Selon une forme de réalisation non représentée, la face externe de chaque bretelle (20, 21) présente une sangle réglable reliée au sommet du dos (3).According to an embodiment not shown, the outer face of each strap (20, 21) has an adjustable strap connected to the top of the back (3).

Avantageusement, l'extrémité de la sangle est fixée à égale distance des deux extrémités de la bretelle.Advantageously, the end of the strap is fixed at equal distance from the two ends of the strap.

En d'autres termes, l'invention permet un réglage facile de la hauteur des bretelles. De plus, ce réglage se fait simultanément sur les deux bretelles, et n'entraîne ainsi aucun déséquilibre de la charge. Ce système est donc adapté à la morphologie du dos de l'utilisateur quel qu'il soit. Le confort lors du portage en est d'autant plus amélioré.In other words, the invention allows easy adjustment of the height of the straps. In addition, this adjustment is made simultaneously on the two straps, and thus does not cause any load imbalance. This system is therefore adapted to the morphology of the user's back, whoever it is. The comfort during porting is all the more improved.

De la sorte, l'invention peut être avantageusement appliquée à des sacs à dos d'alpinisme ou de camping, ainsi que de façon plus générale, à tout dispositif de portage, tels que notamment les porte-enfant ou les claies de portage.In this way, the invention can be advantageously applied to mountaineering or camping backpacks, as well as more generally, to any carrying device, such as in particular child carriers or carrying racks.
