しかしながら、障害の程度が重度の場合、歩行機を使っ
て歩行を行う際に、歩行機の重量が負担になり歩行が非
常にわずられしいものになる。However, if the degree of disability is severe, the weight of the walker becomes a burden when walking using a walker, making walking extremely difficult.
また、障害の程度が軽い場合でも、上り坂など平坦な場
所よりも歩行が困難な時、歩行機を押すのに力がかかり
、歩行さえも困難な上に、歩行機を押さなければならな
いという余計な労力を費やすことになる。In addition, even if the degree of disability is mild, when walking uphill or on a flat surface is more difficult, it takes more force to push the walker, making it difficult to even walk and having to push the walker. It will cost you extra effort.
そして下り坂などの歩行においては、歩行機は自然に下
っていくため、障害者は歩行機が下らないように支えな
がら坂道を下らなければならなかったり、あ−るいは歩
行機の速さにつられて通常の歩行スピードよりも遠い、
無理な速さで歩くことになる。When walking downhill, the walker naturally descends, so a person with a disability may have to support the walker to keep it from going down the slope, or the walker may not be able to handle the speed of the walker. Tired and farther than normal walking speed,
You will be walking at an unreasonable speed.
このように、路面の傾斜によって走行スピードが変化し
、非常に使用性の悪いものであった。In this way, the running speed changes depending on the slope of the road surface, making it extremely difficult to use.
（ハ）発明が解決しようとする課題
本発明は、路面の傾斜状態が変わっても一定の走行スピ

押さえ１３から構成される部分をクラッチ１６という。The drive unit 7 is always pressurized in the direction of the wheels 5 by a pressure spring 11, and a shaft 12 integrated with the drive unit 7 passes through the pressure spring 11. A spring presser 13 for pressing the pressure spring 11 is fixed to the lower frame 1 at the opposite end of the drive unit 7,
The shaft 12 is passed through it. The shaft 12 is a shaft fulcrum 14
As shown in FIG. 2, when the lever 15 is extended, it acts to extend the pressure spring 11, and the front wheel 5 and the driving roller 10 are slid. , thus the front wheels 5 are driven. Further, as shown in FIG. 3, the lever 15 is
When it is bent, the pressure spring 11 is compressed, the front wheel 5 and the drive roller 10 are separated, and the front wheel 5 is released. A portion consisting of the pressure spring 11, the shaft 12, the lever 15, and the spring presser 13 is called a clutch 16.

リー１８によって駆動される。Reference numeral 17 denotes a motor for driving the drive roller 10, and the motor 17 is driven by a battery 18 built into the lower frame I.
１９ハ前記コントロールレバー４によって指示される情
報を、左右一対に設けられた前記駆動ユニット７に伝達
するコントロールボックスである。19C is a control box that transmits information instructed by the control lever 4 to the drive units 7 provided on the left and right sides.
次に、動作について述べる。Next, the operation will be described.
傷害者は下部フレーム１のコの字の最も短い辺を前にし
、脇支え部３の両側部の長い辺に腕を添えるようにして
立つ。そして、コントロールレバー４を前に倒すことに
よって、電動歩行機は前進を始め、このスピードに応じ
て傷害者は歩行の練習を行う。この時、レバー４の倒す
量によってスピードが可変できるようになっている。The injured person stands with the shortest side of the U-shape of the lower frame 1 facing forward, with his arms resting on the long sides of both sides of the armpit support part 3. Then, by tilting the control lever 4 forward, the electric walking machine starts moving forward, and the injured person practices walking according to this speed. At this time, the speed can be varied by the amount by which the lever 4 is pushed.
この歩行機は電動にしたため、上り坂でも歩行機自身の
駆動で坂を登るため、傷害者の歩行機を押す力が省け、
歩く力だけでよく、また、重度の傷害者が平坦な場所に
おいて歩行を行うとき、歩行機を押す力が省け、傷害者
に対しての余計な負担がなくなる。Since this walker is electric, even when going uphill, the walker itself drives itself up the slope, which saves the injured person from having to push the walker.
Only the strength needed to walk is required, and when a severely injured person walks on a flat surface, the force required to push the walker is eliminated, eliminating unnecessary burden on the injured person.
また、下り坂においても、一定のスピードで走行するた
め、速く歩行するというような無理な歩行をしなくても
よい。Furthermore, since the vehicle travels at a constant speed even when going downhill, there is no need to walk too fast.
次に、軽い傷害者が歩行を行ったり、収納場所に歩行機

戻し、クラッチ１６を切り、即ち、レバー１５を折り曲
げ、駆動ローラー１０を車輪５から離し、歩行機を押し
ながら歩行練習を行ったり収納場所まで移動させたりす
る。Next, when a person with a slight injury walks or moves the walker to a storage location, the control lever 4 is returned to the stop position, the clutch 16 is disengaged, that is, the lever 15 is bent, and the drive roller 10 is moved to the wheel 5. Release the walker from the walker, practice walking while pushing the walker, or move it to a storage location.
また、左や右に曲がる場合は、コントロールレバー４を
右や左に倒すことによってコントロールボックス１９が
左右夫々の駆動ユニット７の制御を行う。このレバー４
は右に倒せば右側の車輪５が停止し、左側の車輪５の駆
動によって右折をする。レバー４を左に倒した場合は、
前述の右折とは逆の動作をし、左側の車輪５が停止し、
右側の車輪５の駆動によって左折をする。When turning left or right, the control box 19 controls the left and right drive units 7 by tilting the control lever 4 to the right or left. This lever 4
If you tilt it to the right, the right wheels 5 will stop and the left wheels 5 will drive to turn right. If you move lever 4 to the left,
The operation is opposite to the above-mentioned right turn, and the left wheel 5 stops,
A left turn is made by driving the right wheel 5.
このように、左右別々の駆動ユニット７を設けているた
め、右や左に曲がるときに曲がりやすく、小回りが利く
電動歩行機が提供できる。In this way, since separate left and right drive units 7 are provided, it is possible to provide an electric walking machine that is easy to turn when turning to the right or left and has a small turning radius.
このとき、停止するほうの車輪５を逆回転することによ
って、更に小回りが利くようになる。At this time, by rotating the wheel 5 that is stopping in the opposite direction, it becomes possible to make even tighter turns.
また、駆動ユニット７、バッテリー１８、コントロール
ボックス１９を、歩行機の下方である下部フレーム１に
設けているため、安定した走行ができる。Furthermore, since the drive unit 7, battery 18, and control box 19 are provided in the lower frame 1 below the walking machine, stable running is possible.
