Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a walking aid for persons who have a limb paralysis due to cerebral hemorrhage, an accident, etc., and have one leg inconvenient, and who have difficulty walking on their own.

[0002]

2. Description of the Related Art Conventionally, when a person who has difficulty in walking on his own due to cerebral hemorrhage, an accident, etc., has one leg inconvenienced and he / she has difficulty walking on his / her own, he / she must pull up the one foot on his / her own. It was not easy to move in the direction of travel and it was easy to drag on the ground, making smooth walking difficult. Furthermore, since the strength of the ankle joint is weak, when trying to move one leg,
The fingertips tended to fall easily, the fingertips could get caught on the ground or stairs, and the ankle could be accidentally twisted when landing, resulting in a high risk of falls or injuries.

As a device for assisting the walking, Japanese Patent Laid-Open No.
There is a conventional invention as described in Japanese Patent No. 313553.
In this conventional invention, a sheet-shaped first wearing body is attached to the calf of one foot, the sole of the foot, and the instep, which are difficult to operate.
The second wearing body is attached to the thigh separately from the wearing body so as not to interfere with the bending and stretching motion of the knee joint. Then, the first wearing body and the second wearing body are connected by an elastic body such as a rubber band, and the elastic body is stretched on the upper surface of the ankle and the instep. It is biased upward. By utilizing the urging force of this elastic body, the wearer's fingertips can be lifted upward, and it is attempted to prevent the fingertips from being caught during walking.

[0004]

However, this conventional auxiliary device is a device for lifting only the fingertip part to the upper part, and there is no effect of lifting the entire one leg. Therefore, even if a person who has difficulty in lifting one leg by himself wears it, the heel and the like drag on the ground, which makes it difficult to walk smoothly.

Also, since the toes, calves and the like are covered with a sheet-shaped wearing body, when used in summer etc., there is a possibility that the feeling of wearing may be deteriorated and that the appearance may be deteriorated due to being bulky when wearing clothes. is there. Also, because it is divided into multiple parts,
It took a lot of time to put it on.

SUMMARY OF THE INVENTION The present invention is intended to solve the above-described problems. In order to assist the walking of a person who has difficulty walking on one foot by himself, the entire one foot and the fingertip portion can be easily lifted. (EN) A walking assist tool that enables the user to easily lower the one foot and the fingertip. Further, it is possible to prevent the fingertip portion from being caught on the ground or stairs when walking, and to enable safe and smooth walking without falling or injury. In addition, the mounting method is easy, the appearance at the time of mounting is not impaired, and the product is easy to manufacture and inexpensive.

[0007]

In order to solve the above-mentioned problems, the present invention provides an insertion portion for one leg with a band-shaped elastic body, and a pair of elastic bodies continuously extended from both sides of the insertion portion, After crossing at the intersection of the front of the human body, a tusk part is formed on the shoulder on the side opposite to the one leg, and the elastic body is stretched so that one leg can be biased upward in this tucked state. And connect a pair of elastic bodies on the back side of one leg,
Further, a biasing portion capable of biasing the fingertip portion upward is stretched between the upper front surface of the insertion portion of the one foot and the direction of the fingertip portion of the one foot.

[0008] Further, in the taxi portion, a shoulder pad may be slidably connected to a contact portion with the shoulder portion, and a shift stop string that is fastened to the armpit may be connected to the shoulder pad.

In addition, the taxi portion may be provided with an adjusting portion whose length can be adjusted on the abdomen side.

[0010]

The present invention is configured as described above, and in order to attach a walking aid to one foot that has become difficult to walk by itself due to cerebral hemorrhage, accident, etc., first, in the insertion part of one foot,
Insert one foot from the fingertip side. By this insertion, the strip-shaped elastic body elastically comes into close contact with the surface of one foot, so that one foot does not easily come off from the insertion portion during the walking motion, and stable wearing is possible. By this mounting, the biasing portion is arranged in an extended state between the upper front surface of the insertion portion of the foot and the fingertip direction, and the fingertip portion can be biased upward. Further, since the elastic body can be elastically contracted to adjust the size to some extent, the size of the wearable foot is not limited, and the foot can be used universally for people having a certain width.

When inserting one foot into the insertion portion, the connecting portion of the pair of elastic members is located on the back side of the one leg in order to facilitate the mounting work of the rear leg portion, so that the pair of elastic members can be connected to each other. Perform the insertion operation while paying attention to the crossing part and the taxi part on the front side.

Next, the taxi portion is hung over the wearer's shoulder portion. To do this, on the front side of the wearer, extend a pair of elastic bodies, let the arm and head on the same side as the one leg inserted into the insertion part go under the taxi part, and then with the one leg inserted into the insertion part Hang the tasuki part on the opposite shoulder. The mounting of the walking aid of the present invention is completed by mounting the taper portion on the shoulder portion.

[0013] In this slanted state, a pair of elastic bodies continuously extended from both sides of the insertion portion are arranged in an extended state on the outer circumference of one foot, and the restoring force urges one foot in the upper direction. Since the pair of elastic bodies are connected on the back side of one foot and then intersect on the front side, the pair of elastic bodies does not separate from the one foot even if the bending and stretching operation of one foot is repeated. It is possible to maintain a good wearing state. Further, as described above, since the pair of elastic bodies are connected on the back side of one leg, the elastic body is not arranged on the front surface of the knee, and the bending operation of the knee is not hindered.

The urging force of one leg by the pair of elastic bodies and the urging force of the fingertip portion by the urging portion are such that the center of gravity is not attached to the non-wearing foot side in a state in which it is difficult to bend and stretch by itself. The tensile strength is such that the entire one foot and the fingertips can be easily lifted when moved to. However, when the center of gravity of the body is moved to the one foot side, one foot can easily land on the ground without losing the balance.

As described above, the walking assist tool can be easily mounted in a short time by inserting one foot into the insertion portion and hanging the skid portion around the shoulder portion. Also, because it is made of a band-shaped elastic body, it fits flatly on the human body, and even if you wear clothes while wearing walking aids, it does not become bulky and you can comfortably wear it It will be hard to notice. Also, since it is fastened only to the fingertip side of one foot and only to the shoulder, and the waist and thighs are not tightened with the elastic body, it is possible to prevent raising and lowering of underwear in the toilet etc. even with the walking aid attached. Absent.

In order to walk with the walking aid attached, the healthy non-wearing foot not wearing the walking aid is taken out one step, and the center of gravity is moved to the non-wearing foot.
Next, move the inconvenient one leg in the direction of movement, but the urging force of the pair of elastic bodies lifts the entire one leg upwards. It becomes possible to do. Also, since the fingertip portion is also lifted by the urging force of the urging portion stretched between the front surface of the insertion portion and the fingertip portion direction, when moving one leg, the fingertip portion is caught on the ground, stairs, etc. It is possible to walk smoothly and safely.

When this inconvenient one leg is moved, the weight is moved to the one leg side so that the one leg can be stably landed on the ground against the biasing force of the elastic body. Then, the non-wearing foot can be moved in the traveling direction without any hindrance, with the inconvenient one foot as an axis. Therefore, even a person who has difficulty walking by himself / herself can walk safely and smoothly without falling or injury.

Further, the urging force of the elastic body is concentrated and applied to the shoulder portion around which the taxi portion is stretched, and by using for a long time,
The elastic body may bite into the shoulder and feel pain. Therefore, by disposing the shoulder pad at the contact portion between the skid portion and the shoulder portion, it is possible to disperse the urging force and prevent the elastic body from biting into the wearer, thus reducing the burden on the wearer. Also, if this shoulder pad is slidably connected to the skid portion, the shoulder pad can be moved and arranged at an optimum position according to the height and body type of the wearer. In addition, if this shoulder pad is connected with a slip-prevention string for securing it to the armpit, the stability of the shoulder pad and the skid to the shoulder is improved, and the skid and the shoulder pad are positioned by the action of the wearer. It does not slip off or fall off the shoulder, and you can continue to wear comfortable and functional wear.

Further, since the walking aid is formed of a stretchable elastic body, it can be worn in correspondence with a certain height difference and body shape difference. However, if the height difference and the body shape difference with respect to the wearer as a reference are too large, a good biasing force may not be obtained, and smooth walking may not be possible. That is, when a person with a large height or body is worn, the biasing force of the elastic body is so strong that it becomes difficult to land one foot on the ground, and smooth walking cannot be performed. On the contrary, when a small person wears it, sufficient elastic force of the elastic body cannot be obtained, and one leg cannot be lifted. Therefore, it is necessary to manufacture the walking aid in many sizes according to the height and the body shape, which may increase the cost.

In order to solve the above-mentioned problems, if the adjustment portion which can adjust the length according to the height and body shape of the wearer is provided in the skid portion, one leg is lifted to an appropriate height and moved in the traveling direction. The urging force can be adjusted to make landing easier. Therefore, regardless of the height and body shape of the wearer, it is possible to always exhibit an excellent walking assist function. Further, this adjusting unit can be easily implemented by using a member such as a belt buckle or a button. And this adjustment unit
If it is provided on the abdomen side, the wearer can easily adjust the length by himself, and the hard buckle, buttons, etc. do not irritate the ribs and the like and can be used comfortably.
