Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a walking function recovery training assisting apparatus useful for walking function recovery rehabilitation for persons with impaired lower limb function, and particularly, for adjusting the body support according to the height and posture of the patient. The present invention relates to a walking function recovery training support device which is unnecessary and facilitates linear motion, and surely prevents a patient from falling.

[0002]

2. Description of the Related Art At present, for patients requiring walking training due to lower limb function due to traffic accidents, brain disorders, or other causes, with the help of PT (occupational therapist) and nurses. In addition, step-by-step training is generally performed, starting with training on a ramp and working on parallel bars, walkers, and crutches.

However, for such general training, P
It requires a lot of manpower and time including T. In addition, there is a problem that sufficient training cannot be provided because the number of medical staff is limited.

Therefore, recently, a walking training device which can carry out walking training with a little muscle force and does not require a large number of human hands has become widespread. For example, the present applicant proposes it as Japanese Patent Application No. 4-224787. Has been done.

This walking training apparatus has a rotating mechanism having a central axis, a horizontal rod member supported by the rotating mechanism and horizontally rotating around the rotating mechanism, a body support provided at one end of the horizontal rod member, and a horizontal support member. It has a balance weight provided at the other end of the rod member, and is configured by providing at least two joints on the horizontal rod member.

With such a structure, since a part of the horizontal rod member and the body support can be changed in any direction through the joints, there is a wide variety of gait such as linear motion and other motions in addition to circular motion. Training can be done.

[0007]

However, according to the conventional walking training device, since each part of the horizontal rod member and the body support member are displaced only in the rotational direction,
For example, if the height of the body support tool is different from the height of the fulcrum of the horizontal bar member, the body support tool is linearly inclined from the horizontal bar member to the body support tool. For this reason, the body support must be adjusted horizontally every time the height or posture (for example, sitting or standing) of the patient changes, and the adjustment work is complicated for the disabled person. It is difficult to adjust by itself, and it becomes remarkable especially in persons with severe disabilities such as those with hemiplegia. Further, when the horizontal rod member is linearly inclined, it is difficult to displace each part of the horizontal rod member at each joint, which makes linear movement and other movements using joints extremely difficult or impossible. .

Further, since the rotating mechanism is designed to rotate in an unloaded state, for example, when a patient rolls backward, the patient rotates backward as it is, so that the patient cannot be prevented from falling. Therefore, the patient may be injured such as a fracture or a bruise. Further, there is a problem that the same problem occurs when walking forward, and it cannot be applied to the use such as muscle strengthening for a mildly handicapped person.

Therefore, an object of the present invention is to provide a walking function recovery training support device which does not require complicated work such as adjusting a body support according to the height and posture of a patient and can facilitate linear movement. Is to provide.

Another object of the present invention is to provide a walking function recovery training assisting device capable of surely preventing a patient from falling and strengthening the muscle strength when walking forward.

[0011]

In view of the above problems, the present invention eliminates the complicated work of adjusting the body support according to the height and posture of the patient, and therefore, the arm means supported by the vertical support.
