JPH06205854A - Seat type walk-training machine - Google Patents

Abstract

PURPOSE:To provide a walk-training machine which can be used for a weak patient for whom a conventional walk-training machine cannot be used, and also can be used while a normal work is performed at the same time. CONSTITUTION:This seat type walk-training machine is equipped with a set 1, foot rest 3 which is arranged in front of the seat 1, and driving means 7, 8, 9, 10, 13 to move the foot rest 3 in the longitudinal direction. By this machine, a walk-training can be done under a sitting condition on a seat, and therefore, almost no load is added to legs, and the exercise for knees and ankles becomes possible without interrupting an activity.

Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a stool-type walking training machine, and more particularly, to a walking training machine capable of exercising knees and ankles comfortably while sitting.

[0002]

2. Description of the Related Art If an inpatient or an elderly person does not walk for a long period of time, the knee joint becomes rigid and walking becomes difficult. Therefore, predetermined walking training is performed when returning to society.

As such a walking training machine, one equipped with a belt conveyor rotating at a predetermined speed and a handrail is conventionally used.

However, this walking training machine cannot be used for a patient who has difficulty in self-reliance and whose legs are extremely weak because the weight of both legs is almost entirely applied.

On the other hand, the phenomenon of stiffening of the knee is not limited to the above-mentioned inpatients, but is a problem similarly occurring to general workers who continue working for a long time in the same posture.

[0006] Such a problem can be solved by appropriately moving the knees and ankles at regular intervals during the work, but it is difficult to carry out because it must be periodically performed by one's will. Further, when the above-mentioned conventional walking training machine is used, the normal work has to be interrupted once and cannot be performed in parallel with the work.

[0007]

The present invention has been devised in view of such a situation, and can be used even for a fragile patient who cannot use a conventional walking training machine.
The purpose is to obtain a walking training machine that can be used in parallel with normal work.

[0008]

The walking training machine of the present invention comprises:
In order to achieve the above object, a stool, a footrest placed at a front portion of the stool, and a drive means for moving the footrest back and forth are characterized.

[0009]

According to the walking training machine of the present invention, since walking training can be performed while sitting on a stool, there is almost no load on the foot, and the knee and ankle can be exercised without interruption of work. .

[0010]

DESCRIPTION OF THE PREFERRED EMBODIMENTS FIG. 1 is a perspective view showing the internal structure of a sitting-type walking training machine which is an embodiment of the present invention.

In the figure, reference numeral 1 is a stool, and a height adjusting device 2a is provided at a substantially intermediate position between the four legs 2, and the two front legs 2 are provided.
A guide rail 4 is attached to the. Further, a footrest 3 having wheels 5 at four corners is provided in the guide rail 4.

A motor 7 is arranged below the stool 1 via a mounting plate 6, and a rotary shaft 7 of the motor 7 is provided.
A crank 9 in which a crankshaft 8 is connected is attached to a. Reference numeral 10 is a swing rod having one end fixed to a rotary shaft 12 whose both ends are supported by bearings 11. The lower end is pin-connected to a connecting rod 13 continuously provided on the footrest 3.
Further, a crankshaft 8 is attached at a position about 1/3 from the upper part of the swing rod 10. 14 is a controller,
In addition to a speed controller for adjusting the rotation speed of the motor 7, an on / off switch and a time switch are provided so that the motor 7 can be operated intermittently.

In the above structure, as shown in FIG. 2, the user sits on the stool 1 and puts the foot F on the footrest 3, and operates the height adjusting device 2a so that the height becomes a predetermined height. When the switch of the controller 14 is turned on, the motor 7 operates and the footrest 3 slowly moves back and forth. As a result, the foot F on the footrest 3 reciprocates back and forth around the knee N as a fulcrum, and the knee N can be moved without imposing an excessive burden on the user. At that time, when the footrest 3 moves forward, the ankle A is in a stretched state, and when it is retracted, the ankle A is in a contracted state. As described above, not only the movement of the knee but also the movement of the ankle similar to the actual walking can be simultaneously performed. Further, the present apparatus can be used as a work chair, and at that time, if the controller 14 is set so that the motor 7 is intermittently operated at an appropriate time, the work can be performed normally. It becomes possible to effectively prevent the stiffening of the knees of the person.

FIG. 3 shows still another embodiment, in which the foot rest 20 and the guide rail 21 supporting the foot rest 20 are independent of the stool 22. A driving motor 23 has a feed shaft 26 attached to the rotary shaft of the motor 23, and a receiving screw 27 that meshes with the wheel 24 and the feed shaft 26 is attached to the rear surface of the footrest 20. 25 is a footrest 2
With the sensors provided before and after 0, the footrest 20 is used for the front plate 21a and rear plate 21a of the guide rail 21
When the predetermined interval is reached, the motor 23 is rotated in the reverse direction, whereby the footrest 20 can be moved back and forth. Reference numeral 14 is a controller having the same function as that described in the previous embodiment.

By making the footrest 20 and the guide rails 21 separate and independent from the stool 22 as in this embodiment, it is possible to use a conventional stool.

[0016]

According to the present invention, the following effects can be obtained.

(1) Since it can be used while sitting down, the knees and ankles can be exercised without placing an excessive burden on the knees and ankles, and it can be used for patients who cannot stand independently.

(2) For the same reason, the knee and ankle can be moved without interrupting the work.
