Abstract

A body orthosis having a pair of body protective members adjacent to each other in a vertical direction, in which one of the body protective member 1 is constituted so as to rotate freely with respect to the other body protective member 2, the body orthosis including rotational load setting means 8 for setting a rotational load in one rotational direction of the rotatably constructed body protective member 2 larger than a rotational load in the other rotational direction.

Claims

1. A body orthosis having a pair of body protective members adjacent to each other in a vertical direction, in which one of the body protective members is rotatable with respect to the other body protective member, the body orthosis comprising:

rotational load setting means for setting a rotational load in one rotational direction of the rotatably constructed body protective member larger than a rotational load in the other rotational direction,

wherein the rotational load setting means includes a one-way bearing provided in a rotary shaft portion of the rotatably constructed body protective member,

wherein the body orthosis includes a sole plate for loading and supporting at least a part of a sole, and a leg protective plate for protecting at least a part of a leg, and side ends adjacent to these plates are connected to each other by the rotational load setting means, and

wherein in the case of walking by using the body orthosis, the sole plate is rotated by a load applied at the time of landing the sole plate so as to set its bottom surface parallel to the ground, and when the sole plate is lifted, a size of the rotational load is set so as to maintain the sole plate and the leg protective plate in states immediately before the lifting.

2. The body orthosis according to claim 1, wherein the leg protective plate includes a facies posterior cruris cuff for protecting a calf and a calcaneus portion in the rear side of the sole plate and an Achilles'"'"' tendon portion in a lower end rear side of the facies posterior cruris cuff are formed to be open type.

3. The body orthosis according to claim 2, wherein a rotational center of the facies posterior cruris cuff is set at a height substantially equal to an upper-and-lower position of a foot joint axis of hominal physiology.

4. The body orthosis according to claim 2, wherein an opening is formed in a center of upper and lower sides of the facies posterior cruris cuff.

5. The body orthosis according to claim 2, wherein a fixing member is provided to fix a human body to the facies posterior cruris cuff or the sole plate over left and right front ends of the facies posterior cruris cuff or left and right upper ends of the sole plate.

6. The body orthosis according to claim 1, wherein the leg protective plate includes a facies posterior cruris cuff for protecting a calf, and a calcaneus portion in the rear side of the sole plate and an Achilles'"'"' tendon portion in a lower end rear side of the facies posterior cruris cuff are formed to be open type.

7. The body orthosis according to claim 1, wherein the rotational load setting means is positioned at a rotational joint between the body protective members.

8. A body orthosis comprising:

a sole plate for loading and supporting at least a part of a sole;

a leg protective plate for protecting at least a part of a leg; and

a one-way bearing provided in a rotary shaft portion of the leg protective plate to rotate the sole plate by a load applied at the time of landing the sole plate so as to set its bottom surface parallel to the ground in walking, and maintain the sole plate and the leg protective plate in states immediately before lifting when the sole plate is lifted.

9. Rotational load setting means for a body orthosis comprising:

an outer side member having a circular concave portion inside;

an inner side cylindrical member having a circular convex portion fitted in the outer side member;

a circular one-way bearing inserted into a portion held between the concave and convex portions of the two members;

a stopper portion fitted to the one-way bearing and a disk portion provided in the inner side cylindrical member; and

a screw penetrates a screw hole provided in the stopper portion and a screw hole provided in the outer side member.

10. The rotational load setting means for a body orthosis according to claim 9, wherein the stopper portion has a protruded portion, and is fitted in a long groove provided in the disk portion of the inner side cylindrical member.
