Abstract
Description
- I - La présente invention concerne un dispositif destiné à aider les- I - The present invention relates to a device intended to assist the
piétons à transporter les charges portées au moyen de courroies s'appuyant sur les épaules par exemple dans le cas des sacs pedestrians to transport the loads carried by means of straps resting on the shoulders for example in the case of bags
à dos, des claies, des cartables.on the back, racks, school bags.
Actuellement le portage des sacs à dos et autres charges dorsales peut entraîner une fatigue importante, des douleurs persistantes, des risques pathologiques au niveau de la colonne vertébrale, Currently carrying backpacks and other back loads can lead to significant fatigue, persistent pain, pathological risks in the spine,
ceci en fonction du poids supporté, de la distance parcourue, du type de terrain, de l'âge du porteur. this depending on the weight supported, the distance traveled, the type of terrain, the age of the carrier.
Ces inconvénients du portage dorsal sont à l'origine d'une démotivation certaine pour sa pratique. These drawbacks of backpacking are at the origin of a certain demotivation for its practice.
Le dispositif selon l'invention facilite de façon importante l'usage des matériels cités ci-dessus. The device according to the invention significantly facilitates the use of the materials mentioned above.
Il comporte:It comprises:
- un cadre, composé de deux lattes ( 1) dont les extrémités supérieures ont un écartement réglable. - a frame, composed of two slats (1) whose upper ends have an adjustable spacing.
- deux pièces ( 5) dont l'emplacement situé vers chaque extrémité supérieure des lattes est réglable et qui sont destinées à s'appuyer sur le corps du porteur au niveau des hanches en exercant une - two pieces (5), the location of which towards each upper end of the slats is adjustable and which are intended to rest on the body of the wearer at hip level by exerting a
pression verticale et horizontale tout en pouvant pivoter autour de celles-ci. vertical and horizontal pressure while being able to pivot around them.
- un point d'appui au sol, qui peut être une roue ( 2), un patin, un ski. - a support point on the ground, which can be a wheel (2), a skate, a ski.
- une ou plusieurs entretoises ( 3) fixes qui relient les deux lattes audessus de ce point d'appui. - one or more fixed spacers (3) which connect the two slats above this support point.
- une entretoise (4) mobile le long des lattes qui peut être bloquée au niveau de la position adaptée - a spacer (4) movable along the slats which can be locked at the appropriate position
à la morphologie du porteur et qui comporte un dispositif de maintien de la charge ( 7). to the morphology of the wearer and which includes a load holding device (7).
- une ceinture (6) de conception particulière destinée à solidariser l'ensemble du dispositif au corps - a belt (6) of special design intended to secure the entire device to the body
du porteur.of the wearer.
Effets procurés par le système: le poids de la charge dorsale ( 19) est essentiellement supporté par le sol et les hanches, les bretelles n'exercent plus qu'une faible force sur les épaules mais gardent toute leur efficacité pour le maintien de l'équilibre du système. Les pièces d'appui sur les hanches participent à la bonne tenue du système en même temps qu'à la traction. Le déplacement du porteur est très sensiblement facilité. Le dos du porteur est considérablement soulagé. Le porteur peut à son gré: diminuer sa fatigue, gagner du temps sur son déplacement, Effects provided by the system: the weight of the back load (19) is mainly supported by the ground and the hips, the suspenders do not exert any more than a weak force on the shoulders but keep all their effectiveness for the maintenance of the balance of the system. The support pieces on the hips contribute to the good behavior of the system at the same time as to the traction. The movement of the carrier is very significantly facilitated. The wearer's back is considerably relieved. The wearer can at his discretion: reduce fatigue, save time on the move,
augmenter le poids transporté.increase the weight transported.
La mise en oeuvre du dispositif est la suivante: Réglage, selon la morphologie de l'utilisateur: de l'écartement des deux lattes, de la position des pièces d'appui, de la position de l'entretoise mobile. Mise en place au niveau des hanches des pièces d'appui et blocage de la ceinture. L'utilisateur endosse ensuite, par exemple un sac à dos, de la façon habituelle il effectue éventuellement un réglage de la longueur des bretelles du sac, fait reposer le sac sur l'entretoise mobile, entoure et serre le sac avec la courroie. Très rapidement il perçoit l'effet d'allégement et la facilité de déplacement en terrain accidenté, il peut même effectuer de courtes escalades simples; dans ce cas le sac devient instantanémnent porteur de l'ensemble du système, qui est alors inutilisé mais qui reste peut gênant car la roue qui n'est plus en The implementation of the device is as follows: Adjustment, according to the morphology of the user: the spacing of the two slats, the position of the support pieces, the position of the mobile spacer. Support pieces are placed at the hips and the belt is locked. The user then endorses, for example a backpack, in the usual way he possibly makes an adjustment of the length of the shoulder straps of the bag, rests the bag on the mobile spacer, surrounds and tightens the bag with the strap. Very quickly he perceives the lightening effect and the ease of movement in rough terrain, he can even make short simple climbs; in this case the bag instantly becomes the bearer of the entire system, which is then unused but which can remain troublesome because the wheel which is no longer in
contact avec le sol est tenue éloignée des jambes du porteur. contact with the ground is kept away from the wearer's legs.
-2 - Certaines dimensions sont données ci-après à titre d'exemple pour un utilisateur de taille moyenne: longueur des lattes: 160 cm longueur de l'entretoise mobile: 40 cm longueur du déplacement souhaitable le long des lattes de l'entretoise mobile: 20 cm longueur du déplacement souhaitable le long des lattes des pièces d'appui: 30 cm surface d'une pièce d'appui: 220 cm2 diamètre de la roue: 30 cm Les dessins annexes illustrent l'invention: -2 - Certain dimensions are given below by way of example for a medium-sized user: length of the slats: 160 cm length of the mobile spacer: 40 cm length of the desirable displacement along the slats of the mobile spacer : 20 cm length of the desirable movement along the slats of the supporting parts: 30 cm surface of a supporting part: 220 cm2 diameter of the wheel: 30 cm The accompanying drawings illustrate the invention:
La figure ( 1) et la figure ( 2) représentent le dispositif de l'invention. Figure (1) and Figure (2) show the device of the invention.
La figure ( 3) représente un exemple de liaison entre le dispositif de l'invention et le corps du porteur. La figure ( 4) représente un exemple de dispositif de réglage de l'emplacement de l'entretoise mobile. Figure (3) shows an example of connection between the device of the invention and the body of the wearer. Figure (4) shows an example of a device for adjusting the location of the mobile spacer.
La figure (5) représente un exemple de ceinture de liaison munie de trous au niveau des hanches. Figure (5) shows an example of a connecting belt with holes in the hips.

d'autre part, servir a régler l'écartement entre les extrémités des lattes. on the other hand, serve to adjust the spacing between the ends of the slats.
Il s'agit d'une réglette ( 4) de quelques centimètres de largeur percée de trous (10) alignés selon une direction parallèle à son axe longitudinal et vers ses extrémités. Deux trous sont choisis selon l'écartement demandé et engagés sur deux tiges (12) elles-mêmes solidaires de pièces (1 1) coulissant sur les lattes, ces pièces sont bloquées face à face au moyen de vis ( 13), ainsi la réglette It is a strip (4) a few centimeters wide pierced with holes (10) aligned in a direction parallel to its longitudinal axis and towards its ends. Two holes are chosen according to the required spacing and engaged on two rods (12) themselves integral with parts (1 1) sliding on the slats, these parts are blocked face to face by means of screws (13), thus the strip
peut être positionnée en différents endroits. can be positioned in different places.
- figure 6: dans cette variante la charge ( 19) qui peut être volumineuse est posée sur le support (4), maintenue par des sangles ( 16). Le porteur endosse les bretelles de la plaque ( 15) qui pivote -3- autour de l'articulation ( 14), l'utilisation du systeme d'appui sur les hanches est telle que dans le - Figure 6: in this variant the load (19) which can be bulky is placed on the support (4), held by straps (16).
