(Usage method in the first embodiment)

Next, the method of using the walking aid described above will be described in detail with reference to the drawings. (A) to (d) of FIG. 7 show the use of the walking aid in the first embodiment of the present invention. It is a figure which shows the process when it walks, and is the figure seen from the walk side direction. In the example of this figure, the walking assist mechanism 200 is provided with four wheels 208 in total, two on each side when viewed from the front in the walking direction.

[0034] First, the user stands by placing the knee on the affected foot side on the walking aid (Fig. 7 (a)).

Next, the user pushes the walking aid in the pre-walking direction with the knee on the affected leg side (( b)).

In line with this, the foot on the healthy side is advanced in the direction before walking ((c) in Fig. 7).

In addition, push the walking aid in the pre-walking direction with the knee on the affected foot side so that it can catch up with the position of the foot on the healthy foot that was advanced before (Fig. 7 (d)).

[0035] As described above, by alternately repeating the pushing of the walking aid on the affected foot side and the walking on the healthy foot side, the burden on the affected foot side and the healthy foot side is reduced and smoothly performed. Can walk.

(Operation of walking assist mechanism 200 in the first embodiment)

Next, the operation of the walking assist mechanism 200 during walking will be described.

FIGS. 8A to 8D are diagrams illustrating the operation of the walking assist mechanism 200 during walking. In the following, the operation of the walking assist mechanism 200 when the user starts the stopped state force walking will be described in order according to this figure.

[0037] FIG. 8 (a) shows the state of the walking assist mechanism 200 when walking is stopped. When the user stops, the user puts his / her weight on the support member 103 or the handle member 104 of the walking aid to support the body. The load in the ground direction is finally transmitted to the foot 206 through the tubular member 102, the base member 101, the adjusting shaft 201, and the grounding shaft 205, and the foot 206 is strongly pressed against the ground. Become. Further, the panel 202 wound around the adjustment shaft 201 is held in a compressed state by the load in the ground direction. At this time, the engaging pin 209 moves above the shaft moving hole 201b.

When the foot 206 comes into contact with the ground in this way, the walking aid grasps the ground due to the unevenness provided on the ground contact surface of the foot 206. It can be rotated in the back-and-forth direction of walking, and the user can be prevented from falling by being dragged by this.

[0038] FIG. 8 (b) shows the state of the walking assist mechanism 200 when walking on the walking assisting device side is started.

When walking is started, the weight applied to the walking aid is removed and the restoring force of the panel 202 to extend causes the foot 206 to release ground force. At this time, the engaging pin 209 moves below the shaft moving hole 201b. As a result, during walking, it is not affected by friction due to the unevenness provided on the ground contact surface of the foot 206, and therefore smooth walking is possible.

FIG. 8 (c) shows the state of the walking assist mechanism 200 when walking is started and the foot on the affected foot side is advanced in the pre-walking direction.

As shown in Fig. 7 (b), when the affected foot is advanced forward, the walking aid tilts slightly behind the ground with respect to the ground. At the same time, the walking assist mechanism 200 tilts in the same direction with respect to the ground. At this time, the rear side of the foot 206 in contact with the ground comes into contact with the ground, and the brake force S is applied due to friction.

In addition, when the state force perpendicular to the walking surface of the tubular member 102 to the ground-side shaft 205 is also tilted by about 8 °, a part of the foot 206 is brought into contact with the ground, so that the brake is sufficiently applied. It can be made to act.

[0040] FIG. 8 (d) shows the state of the walking assist mechanism 200 after the brake is applied. When the brake is applied as described above, the brake contacts the ground as shown in the figure. The front side of the foot 206 that has been stiff is also grounded, and the foot 206 is in contact with the ground in the maximum area, and the walking aid is in a state of completely capturing the ground.

At this point, with the ground contact surface of the foot 206 as a fulcrum, move the foot on the healthy foot side in the direction before walking and again return to the state of (a) in FIG. 8 and repeat the walking on the walking aid side This makes it possible to walk smoothly and safely.

In this way, when the foot on the healthy foot side is carried forward, the foot 206 can grasp the tension and the ground on the affected foot side, so that the affected foot side can be smoothly moved without sliding forward. It is possible to walk.

[0041] Next, the operation of the walking assistance mechanism 200 when the walking assistance tool is weighted in the left-right direction when viewed from the walking direction side will be described.

FIGS. 9A to 9C are views of the walking assist mechanism 200 viewed from the front (walking direction side). Hereinafter, the operation of the walking assist mechanism 200 with respect to the load from the left-right direction will be described with reference to the drawing. FIG. 9 (a) is a view of the walking assist mechanism 200 during normal walking as viewed from the front.

As shown in the figure, the ground surface and the ground side shaft 205 are substantially perpendicular. On the other hand, the foot 206 is not in contact with the ground and the brake is not applied.

[0043] FIG. 9B is a view of the rotational drive unit 200 as seen from the front when the user has inadvertently tilted the upper body to either the left or right side.

As shown in the figure, when the upper body is tilted to the left or right, the ground side shaft 205 is slightly inclined with respect to the ground surface, and a part of the bottom surface side of the foot 206 comes into contact with the ground.

Eventually, as shown in FIG. 9 (c), the bottom surface of the foot 206 comes into contact with the entire ground surface and the brake is completely applied.

[0044] As described above, even when the user puts his or her weight on the left and right with respect to the walking direction, the walking aid holds the ground firmly, so that the user can be prevented from falling. It becomes possible.

[0045] Although the brake operation by the foot mechanism 200 has been described above, another brake mechanism may be provided on the walking aid.

For example, a grip lever or the like may be provided on the handle member 104, and the wheel 208 may be moved vertically upward (on the holding mechanism 100 side) when this lever is gripped. For example, when you want to apply a slope or a sudden break, if you hold the lever and move the frame 207 upward, the wheel 208 will also move in the same direction, and the foot 206 will protrude to the walking surface side. Touching and the brake is applied.

As another brake mechanism, it is possible to lock the rotation of the wheel 208 by, for example, bringing a member having frictional force into contact with the wheel 208 by grasping a lever provided on the handle member 104 or the like. But you can.
