Description

La présente invention concerne un dispositif de rappel et de réglage des sangles pour sacs à dos, qui ne bénéficient pour l'instant que de lanières difficiles à régler, encombrantes et pas toujours ergonomiques. The present invention relates to a device for recalling and adjusting the straps for backpacks, which for the moment only benefit from straps which are difficult to adjust, bulky and not always ergonomic.

Le dispositif selon l'invention permet de répondre à ces besoins. Il comporte en effet selon une première caractéristique des sangles de poitrine, ou bretelles mobiles, auto réglables et à encombrement réduit, grâce à un système de mise en tension de celles-ci. The device according to the invention makes it possible to meet these needs. According to a first characteristic, it comprises chest straps, or mobile, self-adjusting straps with reduced bulk, thanks to a tensioning system for these.

Selon une deuxième caractéristique, le dispositif comporte une sangle de taille, ou ceinture mobile, auto réglable et à encombrement réduit, grâce à un système de mise en tension de celle-ci. According to a second characteristic, the device comprises a waist strap, or movable belt, self-adjusting and compact, thanks to a tensioning system thereof.

Selon des modes particuliers de réalisation : Le système peut s'appliquer quelle que soit la taille du sac à dos. According to particular embodiments: The system can be applied regardless of the size of the backpack.

Les dessins annexés illustrent l'invention : Les figures 1 ; 2 ; 3 ; 4 ; représentent l'objet dans ses différentes configurations. The accompanying drawings illustrate the invention: Figures 1; 2; 3; 4; represent the object in its different configurations.

Les figures 5 ; 6 ; 7 ; 8 ; 9 ; 10 ; illustrent une mise en situation de l'invention. Figures 5; 6; 7; 8; 9; 10; illustrate a scenario of the invention.

En référence à ces dessins, le dispositif comporte deux bretelles auto réglables, constituées de parties fixes et de parties mobiles. Ces bretelles sont constituées chacune d'une courroie de poitrine (1), partie mobile, qui vient coulisser et s'accrocher dans des pièces de tissu matelassées appelées fourreaux (2), parties fixes. Les courroies de poitrine (1), de même nature que celles utilisées pour les ceintures de sécurité automobiles, constituent les parties basses des bretelles. L'extrémité inférieure des courroies de poitrine (1) s'accroche et s'enroule aux enrouleurs (3), qui sont des mécanismes de mise en tension, similaires aux dispositifs utilisés dans le domaine automobile. Les enrouleurs (3) sont fixés aux flancs du sac et logés dans des poches latérales (4), possédant chacune une saillie (5) qui permet le passage des courroies de poitrine (1). Les fourreaux (2), de forme courbe, constituent les parties hautes des bretelles, leurs extrémités supérieures s'accrochent à la tête du sac. Leurs extrémités inférieures qui s'associent aux courroies de poitrine (1) présentent des ouvertures et des aménagements particuliers permettant à ces courroies de poitrine (1) d'y coulisser et de s'y accrocher. Les ouvertures sont au nombre de deux par fourreau, en With reference to these drawings, the device comprises two self-adjusting straps, consisting of fixed parts and mobile parts. These suspenders each consist of a chest strap (1), mobile part, which slides and hooks into pieces of padded fabric called sheaths (2), fixed parts. The chest straps (1), of the same kind as those used for automobile seat belts, constitute the lower parts of the shoulder straps. The lower end of the chest straps (1) hooks and winds up the reels (3), which are tensioning mechanisms, similar to devices used in the automotive field. The reels (3) are fixed to the sides of the bag and housed in side pockets (4), each having a projection (5) which allows the passage of the chest straps (1). The sheaths (2), of curved shape, constitute the upper parts of the suspenders, their upper ends clinging to the head of the bag. Their lower ends which are associated with the chest belts (1) have special openings and arrangements allowing these chest belts (1) to slide there and to hang thereon. There are two openings per sleeve, in

forme de fente, l'une se trouve sur le coté extérieur du fourreau, c'est la fente d'entrée (6), l'autre se trouve dans le prolongement du fourreau (2), c'est la fente de sortie (7). Les aménagements particuliers que l'on trouve sont au nombre de deux par fourreau, fixés à la base de ceux-ci et pris en sandwich entre deux épaisseurs de tissu, on distingue la boucle de déviation (8) positionnée à quarante cinq degrés par rapport à chaque fente et la barrette anti-retour (9) qui est un passant de plastique fixé au fourreau (2) et s'alignant parfaitement sur la fente de sortie (7). On comprend donc que les courroies de poitrine (1) pénètrent par les fentes d'entrée (6) puis coulissent dans les boucles de déviation (8) qui comme leur nom l'indique servent à dévoyer les courroies de poitrine (1) et ce, celles-ci étant plates, en les retournant ce qui permet de les faire repartir dans les directions voulues. Pour finir, les courroies de poitrine (1) sortent des fourreaux (2) par les fentes de sortie (7). On peut remarquer que les courroies de poitrine (1) rejoignent les fourreaux (2) de biais et de fait, ceux-ci ont une forme courbe qui permet de créer un angle entre ces deux parties pour améliorer l'ergonomie et éviter que les courroies de poitrine (1) ne développent des plis en amont et en aval des fourreaux (2). Les extrémités des courroies de poitrine (1) sont pourvues de pièces de tissu aux bouts arrondis : les poignées textiles (10), qui sont des éléments de préhension dont les sous faces sont tapissées de pièces de velcro (marque déposée), parties femelles (11). Sur les faces supérieures de chaque poignée textile (10) des courroies de poitrine (1), on trouve fixées des pastilles de plastique, ce sont les pastilles d'arrêt (12) des courroies de poitrine (1). Les pastilles d'arrêt (12) arrivent en butée contre les barrettes anti retour (9) et empêchent les courroies de poitrine (1) de refluer complètement vers les enrouleurs (3) qui exercent sur elles une tension permanente. form of slot, one is on the outer side of the sheath, it is the entry slit (6), the other is in the extension of the sheath (2), it is the outlet slit ( 7). The particular arrangements that are found are two in number per sheath, fixed at the base of these and sandwiched between two thicknesses of fabric, there is the deflection loop (8) positioned at forty five degrees relative to at each slot and the non-return bar (9) which is a plastic loop fixed to the sheath (2) and perfectly aligning with the outlet slot (7). It is therefore understood that the chest straps (1) penetrate through the entry slits (6) then slide in the deflection loops (8) which, as their name suggests, serve to deflect the chest straps (1) and this , these being flat, by turning them over which allows them to start again in the desired directions. Finally, the chest straps (1) come out of the sleeves (2) through the outlet slots (7). It can be noted that the chest straps (1) join the sleeves (2) at an angle and in fact, these have a curved shape which makes it possible to create an angle between these two parts to improve ergonomics and prevent the straps breast (1) do not develop folds upstream and downstream of the sleeves (2). The ends of the chest straps (1) are provided with pieces of fabric with rounded ends: the textile handles (10), which are gripping elements whose undersides are lined with pieces of velcro (registered trademark), female parts ( 11). On the upper faces of each textile handle (10) of the chest straps (1), there are fixed plastic pads, these are the stop pads (12) of the chest straps (1). The stop pads (12) come into abutment against the non-return bars (9) and prevent the chest belts (1) from completely flowing back to the reels (3) which exert permanent tension on them.

Le dispositif comporte également une courroie de taille (13) qui permet un ceinturage de cette partie du corps. Cette courroie de taille (13) auto adaptable est identique aux courroies de poitrine (1) et reprend certaines de leurs caractéristiques. Une des extrémités de la courroie de taille (13) s'accroche et s'enroule à l'enrouleur de taille (14) qui est un mécanisme de mise en tension identique aux enrouleurs de poitrine (3). L'enrouleur de taille (14) est fixé sur le coté extérieur de l'oreille gauche (15) qui est une protubérance de tissu matelassé participant au ceinturage. L'enrouleur de taille (14) est enfermé dans la poche basse (16) pourvue d'une ouverture verticale appelée fente basse (17) qui permet le passage de la courroie de taille (13). L'extrémité libre de la courroie de taille (13) possède une surface de préhension au bout arrondi appelée poignée textile basse (18). Cette poignée textile basse (18) possède en sous face une pièce de velcro (marque déposée) partie femelle (19) et sur sa face supérieure une pastille de plastique fixée au tissu ; c'est la pastille The device also includes a waist strap (13) which allows this part of the body to be belted. This self-adjusting waist strap (13) is identical to the chest straps (1) and incorporates some of their characteristics. One end of the waist strap (13) hooks and winds up on the waist winder (14) which is a tensioning mechanism identical to the chest winders (3). The waist winder (14) is fixed on the outside of the left ear (15) which is a protuberance of quilted fabric participating in the belting. The waist winder (14) is enclosed in the lower pocket (16) provided with a vertical opening called the lower slot (17) which allows the passage of the waist strap (13). The free end of the waist belt (13) has a gripping surface with a rounded end called the low textile handle (18). This low textile handle (18) has on the underside a piece of Velcro (registered trademark) female part (19) and on its upper face a plastic patch fixed to the fabric; it's the pastille

d'arrêt de la courroie de taille (20) qui vient en butée contre le corps de l'enrouleur de taille (14) et empêche que la courroie de taille (13) ne reflue complètement dans son boîtier, celle-ci étant soumise à une tension permanente. stop of the waist belt (20) which abuts against the body of the waist reel (14) and prevents the waist belt (13) from completely backing up in its housing, the latter being subjected to a permanent tension.

L'oreille droite (21), qui est une protubérance de tissu matelassé participant au ceinturage, assure la liaison avec la courroie de taille (13) car elle possède sur sa face extérieure une surface velcro (marque déposée) partie mâle (22) permettant à la surface velcro (marque déposée) partie femelle (19) de la courroie de taille (13) de s'y accrocher. The right ear (21), which is a protuberance of padded fabric participating in the belt, ensures the connection with the waist strap (13) because it has on its outer face a velcro surface (registered trademark) male part (22) allowing to the velcro surface (registered trademark) female part (19) of the waist strap (13) to hang on to it.

Au dessus de chaque oreille on distingue, fixée à elles et au corps du sac, une pièce de tissu destinée à améliorer l'ergonomie : c'est le tissu de maintien (23). Sur chaque tissu de maintien est fixée une surface velcro (marque déposée) partie mâle (24) destiné à accueillir les surfaces velcro (marque déposée) complémentaires, parties femelles (11) des courroies de poitrine (1). Above each ear there is, attached to them and to the body of the bag, a piece of fabric intended to improve ergonomics: this is the support fabric (23). On each retaining fabric is fixed a velcro surface (registered trademark) male part (24) intended to receive the complementary velcro surfaces (registered trademark), female parts (11) of the chest straps (1).

Lorsqu'il est inutilisé, le sac présente un aspect très compact et ce grâce à la tension permanente exercée par les enrouleurs de poitrine (3) sur les courroies de poitrine (1) qui sont maintenues plaquées sur le sac (fig. 1). De même, les oreilles gauche (15) et droite (21) sont rabattues et plaquées contre la base du sac et ce grâce au concours de pièces velcro (marque déposée) parties mâles (25) cousues à la base du sac, côté interne, qui viennent s'accrocher à des pièces velcro (marque déposée) parties femelles (26) cousues sur la face interne des oreilles gauche (15) et droite (21) (fig. l). Dans cette configuration, le sac est peu encombrant car ses sangles ne pendent pas, ne traînent pas par terre, ne gêneront donc pas le porteur ou une tierce personne, elles ne seront pas abîmées. When not in use, the bag has a very compact appearance thanks to the permanent tension exerted by the chest winders (3) on the chest straps (1) which are kept pressed against the bag (fig. 1). Likewise, the left (15) and right (21) ears are folded down and pressed against the base of the bag, thanks to the assistance of Velcro parts (registered trademark) male parts (25) sewn to the base of the bag, internal side, which are attached to Velcro parts (registered trademark) female parts (26) sewn on the inner face of the left (15) and right (21) ears (fig. l). In this configuration, the bag is space-saving because its straps do not hang, do not drag on the ground, will therefore not interfere with the wearer or a third person, they will not be damaged.

Lorsque le porteur se saisit de son sac, il le fait comme avec n'importe quel sac à dos, mais ici sa tâche est simplifiée. En effet pour passer ses bras dans les bretelles il lui faut moins se contorsionner, car sous une légère pression celles-ci s'agrandissent spontanément (facilitant la mise en place du sac) puis se réajustent automatiquement pour s'adapter à la morphologie de la personne (fig. 5). Si le sac est trop chargé celui-ci aura tendance à tomber , déroulant et entraînant avec lui le surplus de courroie de poitrine (1) contenu dans les enrouleurs de poitrine (3). Pour contrecarrer cette éventualité l'enrouleur de poitrine (3) peut disposer d'un système de blocage similaire à ceux employés pour les ceintures de sécurité automobiles. Dès que le sac est installé sur les épaules, il faut supprimer l'excédent de longueur des courroies de poitrines (1), c'est à dire déployer complètement les courroies pour verrouiller le dispositif. Pour ce faire, le porteur doit saisir les poignées textiles (10) des courroies de poitrine (1) de la manière suivante : poignée de gauche pour la main droite et poignée de droite pour la main gauche (fig. 6). When the wearer grabs his bag, he does it as with any backpack, but here his task is simplified. Indeed, to pass his arms through the suspenders, he has to contort less, because under a slight pressure these spontaneously enlarge (facilitating the positioning of the bag) then readjust automatically to adapt to the morphology of the person (fig. 5). If the bag is overloaded, it will tend to fall, unrolling and carrying with it the excess chest strap (1) contained in the chest winders (3). To counteract this possibility, the chest winder (3) may have a locking system similar to those used for automobile seat belts. As soon as the bag is installed on the shoulders, remove the excess length of the chest straps (1), that is, fully deploy the straps to lock the device. To do this, the wearer must grasp the textile handles (10) of the chest straps (1) as follows: left handle for the right hand and right handle for the left hand (fig. 6).

Cette manière de procéder évite qu'un bras ne passe sous une courroie de poitrine (1) ce qui en gênerait la manipulation. Une fois saisies les poignées textiles (10) il faut tirer à fond sur les courroies de poitrines (1) pour amener leurs extrémités au niveau des tissus de maintien et mettre en relation les surfaces velcro (marque déposée), parties femelles (11) avec les surfaces velcro (marque déposée), parties mâles (24), (fig. 7). Une fois cette opération effectuée, le sac est solidaire du corps. This procedure prevents an arm from passing under a chest strap (1) which would hinder handling. Once the textile handles (10) have been grasped, the chest straps (1) must be pulled as far as possible to bring their ends to the level of the holding fabrics and to put the velcro surfaces (registered trademark), female parts (11) in contact with Velcro surfaces (registered trademark), male parts (24), (fig. 7). Once this operation has been carried out, the bag is secured to the body.

Le porteur à la possibilité d'améliorer la tenue de son sac, c'est à dire qu'il peut s'il le désire, opérer un ceinturage au niveau de la taille. Cela consiste à saisir la poignée textile basse (18), (fig. 8) afin d'étirer la courroie de taille (13) pour amener son extrémité au niveau de l'oreille droite (21) et mettre en relation la surface velcro (marque déposée), partie femelle (19) de la courroie de taille (13) avec la surfaces velcro (marque déposée), partie mâle (22) de l'oreille droite (21). (fig. 9). The wearer has the possibility of improving the holding of his bag, that is to say that he can, if he wishes, operate a belt at the waist. This consists in grasping the lower textile handle (18) (fig. 8) in order to stretch the waist strap (13) to bring its end to the level of the right ear (21) and to put the velcro surface in relation ( registered trademark), female part (19) of the waist strap (13) with the velcro surfaces (registered trademark), male part (22) of the right ear (21). (fig. 9).

Une fois toutes les courroies en place, le sac est étroitement lié à son porteur car il colle au plus prés du corps, au niveau du thorax le croisement des courroies de poitrine (1) atténue les mouvements latéraux du sac lorsque l'on se met à courir, (fig. 10). Once all the straps are in place, the bag is closely linked to its carrier because it sticks as close to the body as possible, at the level of the chest, the crossing of the chest straps (1) reduces the lateral movements of the bag when you put yourself to run, (fig. 10).

Quand le porteur veut se défaire de son sac il lui suffit de dégrafer toutes les courroies qui rentrent instantanément dans leurs logements. Se défaire de son sac ne lui prendra alors pas plus d'effort que lors de son installation.When the wearer wants to get rid of his bag, all he has to do is loosen all the straps that instantly return to their slots. Getting rid of his bag will then take no more effort than when installing it.
