Definitions

  • the present invention relates to an exercise assisting device that can obtain an exercise effect without performing spontaneous (active) exercise.
  • the passive movement is an exercise in which the user expands and contracts the muscle group by applying an external force to the user's body without spontaneously exerting the muscle strength. That is, by using such an exercise assisting device, the user can obtain the same exercise effect as when the muscles are spontaneously exerted.
  • the posture during use varies depending on the muscle group to be expanded and contracted.
  • an exercise assisting device used in a standing position by a user.
  • Japanese Laid-Open Patent Publication No. 2003-290386 and Japanese Laid-Open Patent Publication No. 10-55131 describe devices that simulate walking motion.

  • the user is caused to perform a pseudo skating operation by combining each step with a forward / backward / left / right linear reciprocating motion. That is, the nervous system is reflexed so as to maintain balance by shifting the position of the user's center of gravity back and forth and left and right, and the muscle group is expanded and contracted. Therefore, the user does not need to exercise voluntarily or actively, and can simply move on the step and move dynamically as the step moves.

Therefore, when the load applied to the outer side of the placement unit is larger than the load applied to the inner side (that is, when it is an O-leg), the inner side of the lower limb is greater than when the foot width direction is horizontal. The load that is applied increases. Thereby, the muscle group inside the lower limb can be trained intensively. On the other hand, when the load applied to the inner part of the placement part is greater than the load applied to the outer part (that is, when it is an X leg), the outer side of the lower limbs is greater than when the foot width direction is horizontal. The load that is applied increases.

Therefore, in either case of the O leg or the X leg, it is possible to improve the balance (ability imbalance) between the outer muscle group and the inner muscle group of the lower limbs. As a result, distortion of the lower limb skeleton can be eliminated (alignment of the lower limb skeleton).
  • the user can be exercised in a state in which the balance of the load on the lower limb is adjusted (the load applied on the outer side of the lower limb and the load applied on the inner side are substantially equal). As a result, the load on the knee joint is reduced, so that knee pain during exercise (during exercise) can be alleviated. Therefore, even a person who feels knee pain during walking or the like can perform passive movement without difficulty.

La partie support (1) comprend une paire de repose-pieds (4) comportant des parties placement (40), sur lesquelles l'utilisateur place le pied droit et le pied gauche individuellement. Le dispositif d'entraînement (2) est constitué de sorte que le corps de l'utilisateur soit déplacé par la partie support (1) de façon telle que les charges à appliquer aux membres inférieurs de l'utilisateur puissent varier. Le système d'aide à l'exercice comprend en outre un dispositif de basculement (A). Ce dispositif de basculement (A) comprend une unité de détection de charge (5), une unité de mécanisme de basculement (6) et une unité de commande (8). L'unité de détection de charge (5) est composée de deux détecteurs de charge (50) montés individuellement sur les parties latérales externes (40a) et les parties latérales internes (40b) des parties placement (40). L'unité de mécanisme de basculement (6) est constituée de façon à incliner les parties placement (40) vers les côtés externes ou internes des pieds. L'unité de commande (8) est constituée de façon à commander l'unité de mécanisme de basculement (6) de sorte que la différence entre les charges détectées individuellement par les deux détecteurs de charge (50) tende à se réduire.
