Abstract

L'invention concerne un cadre de dos (10), comprenant : une courroie d'appui (13), qui est destinée à coopérer avec et soutenir une partie de hanche d'un corps humain ; un support (20), qui est destiné à être placé sur le dos du corps humain ; et deux tiges d'épaule (11), qui sont destinées à être disposées sur un côté supérieur de deux épaules du corps humain ; une extrémité avant de chaque tige d'épaule (11) s'étend jusqu'à une extrémité avant d'une partie d'épaule du corps humain, pendant qu'une extrémité arrière de chaque tige d'épaule (11) est reliée à une extrémité supérieure du support (20), et une extrémité inférieure du support (20) est reliée à la courroie d'appui (13). L'invention concerne également un dispositif de transport auxiliaire pouvant être porté. Lorsque le cadre de dos (10) est en utilisation, les extrémités avant des tiges d'épaule (11) peuvent être reliées à un objet lourd de charge au moyen d'un cordon et analogue ; et, de ce fait, lorsque l'objet lourd est transporté, la charge sur les bras peut être réduite au moyen de la force de traction des tiges d'épaule (11), et la force sur les tiges d'épaule (11) peut être transférée à la partie de hanche du corps humain au moyen du support (20) et de la courroie d'appui (13), réduisant ainsi la force sur une partie de taille et de dos du corps humain, protégeant ainsi la taille et la colonne vertébrale, et réduisant la contrainte musculaire et la fatigue corporelle.
