Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a walking aid.

[0002]

2. Description of the Related Art Conventionally, as a walking aid for assisting a person with disabilities in lower limbs, as shown in FIG. 4, a leg fixing part 10 for fixing a leg 8 to a shoe body part 11 for putting in a foot is connected. What has been proposed. The leg fixing part 10 is provided with a strap part 9 wrapped around the leg 8 at the upper end to restrain the leg 8,
It is rotatably connected to the shoe body 11 by a predetermined angle, or is fixed to the shoe body 11 at a predetermined angle.

[0003]

However, in the above-described conventional example, the walking aid is provided on the shoe body 11 with the leg fixing portion 1.
0 are inseparably connected and integrated, causing the following problems. That is, the leg fixing part 1 is attached to the shoe body 11.
Since it is necessary to form the connecting means 12 and the like having a predetermined strength with a predetermined strength, the connecting means 12 is unnecessarily large, gives a strict feeling as a whole, and has a poor appearance. The shoe body 11 has a leg fixing part 1.
Since the zero connecting means 12 must be formed in advance, the cost increases, and it becomes impossible to supply various sizes and designs, and the user has a very narrow choice. .

The present invention has been made to solve the above-mentioned drawbacks, and has as its object to provide a walking aid that is inexpensive and can be worn by a user on his / her favorite shoes.

[0005]

SUMMARY OF THE INVENTION According to the present invention, the above object is achieved by extending upward along the shoe 1 from both ends of an engaging plate 3 which is detachably engaged with a front end rising wall 2a of a heel 2 of the shoe 1. A U-shaped cross-section shoe mounting portion 5 having a rising portion 4 extended,
A leg fixing portion 10 in which a strap portion 9 capable of restraining a leg 8 is fixed to a rigid connecting rod 7 connected to the upper end of the rising portion 4 of the shoe mounting portion 5 via an angle adjusting portion 6; This is achieved by providing a walking aid that can be attached to the shoe 1.

According to the present invention, while the desired shoes 1 are worn, the locking plate 3 is stepped on, and
Is wound around the leg 8 and fixed, the locking plate 3
Of the heel 2 at the front end rising wall 2a.
In this state, when the leg 8 is tilted slightly forward to walk forward, the connecting rod 7 fixed to the leg 8 follows the movement of the leg 8. On the other hand, as shown in FIG. 1, a front end rising wall 2a of a heel 2 of a shoe 1 generally has an ankle 1 serving as a rotation center of a leg 8.
3, the force F applied to the locking plate 3 locked to the front end rising wall 2a is
When the relative position between the strap portion 9 and the locking plate 3 is constant, the strap portion 9 faces substantially the horizontal direction Fh.

Accordingly, if the angle between the locking plate 3 and the connecting rod 7 is determined so that the ankle 13 in the angle adjusting section 6 can maintain the predetermined angle θ, as in the conventional example, the shoe body 11 It is possible to support the forward leaning weight when leaning forward in the direction of arrow A in FIG. 1 without integrating the leg fixing portion 10 into the Since it is regulated by the heel 2, the auxiliary tool does not easily come off the shoe 1. As a result,
People with disabilities in lower limbs simply wear the walking aid of the present invention,
You can wear your favorite shoes 1.

The angle adjusting unit 6 can be variously deformed depending on the degree of a walking obstacle or the like. For example, when the foot 14 cannot be moved at all with respect to the leg 8 and the purpose is only to support the weight. As described above, it is desirable that the angle adjustment unit 6 be completely fixed after the adjustment. On the other hand, if the foot 14 can be moved, it is desirable to use an angle adjusting unit 6 that allows rotation during use. In this case, the rotation area is appropriately regulated by stopper means, and It is configured to support the weight at the end position of the inclined rotation stroke.

[0009]

2 and 3 show an embodiment of the present invention. The walking aid is configured by connecting a leg fixing part 10 to a shoe mounting part 5. The shoe mounting portion 5 is formed in a substantially U-shaped cross section by bending the rising portion 4 upward from both ends of the flat locking plate 3 substantially equal to the width dimension of the shoe 1. The rising portion 4 is slightly inclined to the ankle 13 side in a side view, and care is taken so as not to protrude from the instep of the foot 14.

A leg fixing part 10 is connected to a rising part 4 of the shoe mounting part 5 via an angle adjusting part 6. The leg fixing part 10 has a steel connecting rod 7, and a strap part 9 is fixed to an upper end of the connecting rod 7. As shown in FIG. 3, the strap portion 9 is formed by reinforcing one surface of a belt member 9a made of a flexible and strong material such as cloth or leather with a reinforcing band 9b made of a steel plate. By fastening the connected portion 15, it can be wound and fixed to the leg 8. The connecting portion 15 can have an appropriate configuration such as a buckle, for example. In this embodiment, as shown in FIG.
It is composed of a rectangular ring 15a connected to one side and a fastening band 15b connected to the other side. After the fastening band 15b is inserted through the rectangular ring 15a, the hook-and-loop fastener 15c formed at the distal end of the fastening band 15b is used as a base end. The strap portion 9 can be connected in a loop shape by attaching the strap portion 9 to the strap portion.

As shown in FIG. 3, the angle adjusting section 6 is constituted by pivotally supporting the connecting rod 7 and the rising section 4 of the shoe mounting section 5 by a supporting shaft 6a. In order to maintain the angle of the connecting rod 7 with respect to the mounting part 5 at a predetermined value, the tip of the adjusting screw 6b screwed to the connecting rod 7 side abuts against the stopper wall surface 4a of the rising part 4 to bend the angle. Is not smaller than a predetermined angle.

Therefore, in this embodiment, the user first steps on the locking plate 3 while wearing his / her favorite shoes 1, and furthermore, places the strap portion 9 on a predetermined position of the leg 8, for example, a calf. Just by winding and fixing, the ankle is fixed at the angle θ adjusted by the angle adjusting unit 6, so that walking by itself is possible. Note that FIG.
As shown by a dashed line in FIG.
If the auxiliary belt 16 for holding the instep is connected, it is possible to completely prevent the vehicle from sliding down while walking. If the connecting rod 7 is provided with a length adjusting mechanism for adjusting the length, versatility is improved.

In the above description, since the angle adjustment unit 6 does not rotate during walking once adjusted, it is effective when the ankle is completely fixed to assist walking. If there is an obstacle that does not require the ankle to be completely fixed, the angle adjustment unit 6 may be configured as a rotatable node. In this case, the angle adjustment unit 6 is an ankle 1
When it is located at or near 3, the ankle can be bent freely, and walking can be facilitated. In order to enable the rotation of the angle adjustment unit 6, the support shaft 6a in FIG.
The forward rotation rotation stroke is regulated by b, and the weight can be supported.

[0014]

As is apparent from the above description, according to the present invention, since the shoe body is not required, the manufacturing cost is reduced. People with disabilities can also walk with their favorite shoes.
