FIG. 10 is a schematic front view, FIG. 11 is a schematic rear view, and FIG. 12 is a schematic left side view of the mounting system of one embodiment of the present invention connected with an assist device. The mounting system is similar to that shown in FIGS. 1-9, and a description of common parts will be omitted.

The assist device 8 mounted using the mounting system 1 includes a first auxiliary unit 21a and a second auxiliary unit 21b as power generation units, and a first transmission unit 22a and a second transmission unit 22b as transmission units. . As the first auxiliary unit 21a and the second auxiliary unit 21b, from the viewpoint of light weight and excellent wearability, it is preferable to use an elastic body such as a spiral spring or a compression coil spring as a power generation means (power source). . The first transmission unit 22a and the second transmission unit 22b transmit the power generated by the auxiliary unit to the thigh so as to assist the motion of the wearer, specifically, the motion of raising the upper body.

The auxiliary units 21a, 21b are provided with a rotatable first gear (not shown), and the transmission units 22a, 22b are connected to the rotating shaft of the rotatable first gear and are mounted on the front surface of the thigh. Attachable lower leg rods 50a, 50b and a transmission mechanism for transmitting rotation of the first gear to the lower leg rods 50a, 50b or transmitting rotation of the lower leg rods 50a, 50b to the first gear preferably. As such an auxiliary unit, lower leg rod and transmission mechanism, for example, those described in JP-A-2020-110870 can be used.

For example, the auxiliary units 21a and 21b have a first rotation shaft, a first pulley rotatable about the first rotation shaft, and a first pulley provided on the first rotation shaft, and the rotation angle of the first pulley an elastic body for applying a corresponding force to the first pulley; a cord-like body having a first end connected to the first pulley; a second end of the cord-like body connected to a second rotating shaft; a second pulley rotatable about the center, the second pulley having an outer diameter larger than the outer diameter of the first pulley; and a first gear that has more teeth than the second gear and can be fitted with the second gear, the first gear being rotatable about a third rotation axis The lower leg rods 50a and 50b are connected to the third rotating shaft, the cord-like body is wound around the outer peripheral surfaces of the first pulley and the second pulley, and the elastic The urging force of the body rotates the first pulley to wind the cord-like body around the first pulley, and unwinds the cord-like body from the second pulley to rotate the second pulley and the second pulley. The rotation of the two pulleys rotates the second gear and the first gear, and the first gear rotates the leg rod via the transmission mechanism.

The leg rods 50a, 50b each have a leg rod connection 51a, 51b, a hinge 52a, 52b, a pad support 53a, 53b, and the pad support 53a, 53b includes a thigh attachment pad 60a, 60b. The lower leg rods 50a, 50b are attached to the thighs by bringing the thigh attachment pads 60a, 60b into contact with the front surfaces of the thighs.

In one or more embodiments of the present invention, although not particularly limited, the surface on the side to which the lower leg rods 50a and 50b of the first gear are connected is provided with a substantially fan-shaped depression centered on the rotation axis. there is The recess has a first sidewall and a second sidewall. The lower leg rod connecting portions 51a and 51b are elongated plate-like members thinner than the depth of the depression, and are rotatable inside the depression along the plane of the bottom of the depression. When the leg rod connecting portions 51a, 51b and the first side wall abut, the rotation of the leg rods 50a, 50b can be transmitted to the first gear, and the rotation of the first gear is transmitted to the leg rods 50a, 50b. become transmissible. In this case, the recess, the side wall and the leg rod connecting portion 51a constitute the transmission mechanism. The transmission mechanism includes a first mode in which the lower limb rod connecting portions 51a and 51b do not rotate the first gear, and a first mode in which the lower limb rod connecting portions 51a and 51b apply a rotational force to the first gear to rotate the first gear. It is possible to switch between the second mode of rotating the . The shape of the first gear is not particularly limited to the shape described above, and may be any shape as long as it forms a transmission mechanism together with the leg rod connecting portion 51a.

As the elastic body, for example, a spiral spring formed by winding a plate-like member in the plane direction may be used and held inside the case. Even in the initial state (the state in which no load is applied to the first gear by the leg rod), the elastic body is wound up by a certain number of rotations, and the wound up state is maintained. Thereby, the strength of the biasing force of the elastic body can be adjusted.

When the wearer moves in a bending direction, the lower leg rods 50a, 50b and the first gear rotate clockwise against the biasing force of the elastic body, and the rotation of the first gear rotates the second gear and the first gear. The second pulley rotates against the biasing force of the elastic body. Further, the rotation of the second pulley causes the cord-like body to be unwound from the first pulley and wound around the second pulley, thereby rotating the first pulley against the biasing force of the elastic body.

When the wearer moves in the direction of stretching the waist, the elastic body exerts a restoring force that pulls the pulled-out cord-like body back to its original position. That is, the urging force of the elastic body rotates the first pulley, winds the cord-like body around the pulley body of the first pulley, and unwinds the cord-like body from the second pulley, so that the cord-like body is attached to the second pulley. is rotated, and the rotation of the second pulley rotates the second gear and the first gear, respectively, thereby returning the leg rods 50a and 50b to their original positions.

By using such an auxiliary unit, lower limb rods, and transmission mechanism, it is possible to assist the hip extension movement when getting up from a forward bending posture with a simple configuration without using an external power source such as electricity. Moreover, since the biasing force of the elastic body can be amplified in two stages, the lower limb rod can be biased with a force greater than the biasing force of the elastic body. As a result, an assisting force larger than the urging force of the elastic body can be generated, and the user's motion to return the waist to the upright state can be efficiently assisted.

Further, while the lower limb rods 50a and 50b are moving within a predetermined angle, for example, while the wearer is walking, the lower limb rods 50a and 50b idle, so no assist force is generated. Therefore, the movement of the user is not hindered during walking. In addition, since the presence or absence of the assist is switched according to the relative angle between the lower leg rod and the first gear, there is no need to perform a switching operation to determine whether or not to generate the assist force, and usability can be improved.

By the waist belt 23, the left and right power generation means, specifically the auxiliary units 21a and 21b, can be held outside the buttocks, for example, near the greater trochanter.

The waist belt 23 can be rotatably connected to the left and right power generation means, specifically the auxiliary units 21a and 21b. The left and right power generation units, specifically the auxiliary units 21a and 21b, are provided with plate-like connecting portions 30a and 30b through which the rotating shaft is inserted. It is rotatable around the center. The connecting portions 30a and 30b are provided with plate-like connecting portions (not shown) through which the rotating shaft is inserted, and the waist belt 23 is connected to the connecting portions.

By interposing the connecting portion between the left and right power generation means, specifically the auxiliary units 21a and 21b and the waist belt, the rotating shafts of the connecting portions 30a and 30b and the auxiliary units 21a and 21b are connected. The rotation shafts of the portions 30a, 30b and the waist belt 23 can be arranged at different positions. Therefore, the rotational motion of one of the auxiliary units 21a and 21b and the waist belt is not directly transmitted to the other, and can be rotated independently. Further, the auxiliary units 21a and 21b rotate according to the angle of the thighs, while the waist belt 23 rotates according to the angle of the waist. In the human body, the rotation axis of the thigh and the rotation axis of the waist are different in height in the vertical axis direction. On the other hand, by arranging the rotating shafts of the connecting portions 30a, 30b and the auxiliary units 21a, 21b and the rotating shafts of the connecting portions 30a, 30b and the waist belt 23 at different positions, the connecting portions 30a, 30b and the auxiliary unit 21a , 21b is approximately coincident with the rotational position of the user's thighs, and the rotational axis of the connecting portions 30a, 30b and the waist belt 23 is approximately coincident with the rotational position of the user's waist. This makes it easier for the assist device to follow the forward bending motion of the human body.

The back connecting member 24 can connect the left and right power generation units, specifically the auxiliary units 21 a and 21 b, and the back supporting member 25 .
