  • the stay 43 is adjusted so that the trainee U is set at the allowable motion limit for the trainee U against the fall of the upper body in the forward direction. For this reason, the forward lean prevention means 4 2 serves as a function to call attention to the fall of the upper body.If the limit of the trainee U is exceeded, the fall prevention band 44 prevents the fall. Work. Therefore, within the allowable movement range of the trainee U, walking using the motion of the upper body can be safely performed.
  • FIG. 9 is an external view of the handle 19.

  • the emergency stop switch 46 is used for emergency stop of the human assist device 1 by the trainee U in case of danger or the like, and one emergency stop switch 46 is provided at the center of the handle 19, or left and right. There are two of them. Thereby, for example, even a person whose left or right body is paralyzed can be operated by himself.
  • the shape of the handle 19 is a semicircle, the grip 45 may be horizontal like a parallel bar.
  • the tip of the long follower link 17 follows the movement of the drive links 12 and 13 and the tip of the long follower link 17 becomes sagittal It can move in the area of the area. Accordingly, the gripping means 2 also operates in the sagittal plane ⁇ , and the human body assisting device 1 exerts a force on the trainee U in the sagittal plane via the gripping means 2.
  • the rotation mechanism 7 is controlled so that the deviation between the information from the left and right angle sensors 14, the angular velocity sensor 15 and the force sensor 5 provided in the rotation mechanism 7 and the command value from the control device 4 falls within the opening.
  • the control is performed, and as a result, the leading end of the long driven link 17, that is, the gripping means 2 performs the following operation.
  • a function 47 showing the relationship between the initial standing position and the displacement between the position during exercise and the force is set for each of the two directions, the vertical direction and the traveling direction.
  • a combination of linear functions whose slope was changed according to the magnitude of the deviation was used. This has the effect of both correcting the posture and reducing the load.
  • the vertical direction is positive in the vertical direction and the forward direction is positive in the traveling direction.

  • the torque target value is determined.
  • the force sensor information is also converted into the actual torque of the link mechanism 6 by the force-to-torque converter 49, and the rotation mechanism is controlled by the control system of the combination of the feedforward and the feedback. It becomes the command value to 7.
  • the gripping means 2 is provided with a reaction force that balances with the target value of the force at the time of the operation.
  • a support arm for supporting the lower back of the trainee and a rear fall prevention belt for supporting the rear of the lower back or a body holding belt for holding the lower back and the crotch are provided.
  • the prevention means it is possible to safely walk with freedom of movement of the upper body.
  • the burden on the trainee can be reduced.
  • the rear fall prevention belt and the body holding belt can be changed and used. Depending on the recovery status of the trainee, assistance can be provided.

Abstract

L'invention concerne un dispositif d'assistance au corps humain, lequel aide un sujet à s'entraîner à la marche ou à se déplacer sans lui entraver le tronc ou lui causer de douleur. Ce dispositif peut apporter au sujet des appuis appropriés à la nature de sa rééducation et est absolument sans danger. Ce dispositif comporte un bras de support (20) destiné à supporter la région lombaire antérieure et latérale d'un sujet (U) ainsi qu'une sangle (21) destinée à empêcher une chute en arrière et à supporter la région lombaire postérieure, ou bien une sangle (23) destinée à maintenir le corps et notamment la région lombaire et la hanche sans défaillance, le sujet (U) étant maintenu au niveau de la région lombaire seule ou bien au niveau de la région lombaire et de la hanche. Par ailleurs, le dispositif comprend un guidon (19) permettant de soutenir le corps par lui-même, une sangle (22) destinée à empêcher l'accroupissement et à soutenir la partie inférieure de la hanche, ainsi qu'un moyen (42) destiné à empêcher l'antéversion et notamment la chute du tronc, ce qui permet au sujet de marcher en toute sécurité, le tronc pouvant se mouvoir librement.
