It is what.

この発明の歩行車によれば、手押し状態で自然に腕が動かされるので、腕の機能回復を早める。また、腕の動きは足の動きに連動するので、進行方向に腕を動かしているのと同様の状態となり、リハビリ効果も高いものである。また、正常な歩容に近づける歩行介助となる。さらに、歩行の際、体幹の回旋の動きがみられない多くの高齢者、軽度のパーキンソン病の患者等の歩行訓練として、そして日常の生活の中でも利用できる。   According to the walking vehicle of the present invention, the arm is naturally moved while being pushed, so that the recovery of the function of the arm is accelerated. In addition, since the movement of the arm is linked to the movement of the foot, the state is the same as when the arm is moved in the traveling direction, and the rehabilitation effect is high. In addition, it helps walking closer to a normal gait. Furthermore, it can be used as a walking training for many elderly people who do not see the rotation of the trunk during walking, patients with mild Parkinson's disease, and in daily life.

以下、この発明の歩行車１０の一実施形態について、図１〜図５に基づいて説明する。この実施形態の歩行車１０は、図１、図２に示すように、後輪２０が取り付けられたメインフレーム１２ａと、前輪２４を３６０度の方向に首振り可能に取り付けられたフロントフレーム１２ｂと、後述するスライダ１６が取り付けられた略水平部分を形成するサイドフレーム１２ｃとを組み合わせて構成されたフレーム体１２が、連結フレーム１３によって左右一対に連結され、４輪の車台を構成している。なお、各フレームは、アルミなどの金属製のパイプ材を適宜切断して組み合わせたもので、溶接または螺子止めにより組み立てられている。   Hereinafter, an embodiment of a walking vehicle 10 according to the present invention will be described with reference to FIGS. As shown in FIGS. 1 and 2, the walking vehicle 10 of this embodiment includes a main frame 12a to which the rear wheel 20 is attached, and a front frame 12b to which the front wheel 24 is attached so as to be able to swing in the direction of 360 degrees. A frame body 12 configured by combining a side frame 12c forming a substantially horizontal portion to which a slider 16 to be described later is attached is connected to a pair of left and right by a connecting frame 13 to form a four-wheel chassis. Each frame is formed by appropriately cutting and combining metal pipe materials such as aluminum, and is assembled by welding or screwing.

サイドフレーム１２ｃは下方に向かって僅かに湾曲しており、サイドフレーム１２ｃの上部には、ハンドル１４が立設されたスライダ１６が前後方向に摺動自在に各々設けられている。また、メインフレーム１２ａには後輪２０の回転を制動するブレーキ２６を備えており、ブレーキ２６は各ハンドル１４に併設したブレーキレバー２８によって制御される。   The side frames 12c are slightly curved downward, and sliders 16 on which handles 14 are erected are provided on the upper portions of the side frames 12c so as to be slidable in the front-rear direction. Further, the main frame 12a is provided with a brake 26 that brakes the rotation of the rear wheel 20, and the brake 26 is controlled by a brake lever 28 provided to each handle 14.

ハンドル１４の摺動部であるスライダ１６には、連結棒１８の一端が軸着され、連結棒１８の他端は、後輪２０のホイール２０ａに軸着されている。一対の連結棒１８は、互いに後輪２０の回動角に対して、相対的に１８０°位相がずれて連結されている。即ち、一対の連結棒１８は、例えば図１に示すように、車体の左側フレーム体１２では、連結棒１８の端部はホイール２０ａの回転軸から半径方向に離れた連結点ａに軸着され、車体の右側のフレーム体１２では、連結点ａと回転軸を挟んで反対側の連結点ｂに軸着される位置関係にある。この連結棒１８のホイール２０ａでの軸着位置は、後輪２０の回転軸から半径方向に離れた連結点ａ，ｂが互いに対称位置で半径方向に変更可能であり、固定位置を複数にまたは任意に設定しても良い。さらに、連結棒１８の端部をホイール２０ａの回転軸部に軸支することにより、連結棒が動かないものとすることができるようにしても良い。   One end of the connecting rod 18 is pivotally attached to the slider 16 which is a sliding portion of the handle 14, and the other end of the connecting rod 18 is pivotally attached to the wheel 20 a of the rear wheel 20. The pair of connecting rods 18 are connected with a phase difference of 180 ° relative to the rotation angle of the rear wheel 20. That is, for example, as shown in FIG. 1, in the left frame body 12 of the vehicle body, the pair of connecting rods 18 are pivotally attached to the connecting point a that is radially away from the rotation axis of the wheel 20a. In the frame body 12 on the right side of the vehicle body, there is a positional relationship in which the connection point a and the connection point b on the opposite side across the rotation shaft are axially attached. The connecting position of the connecting rod 18 on the wheel 20a can be changed in the radial direction at the connecting points a and b which are separated from the rotation axis of the rear wheel 20 in the radial direction. It may be set arbitrarily. Furthermore, the end of the connecting rod 18 may be pivotally supported on the rotating shaft portion of the wheel 20a so that the connecting rod cannot move.

また、左右一対のフロントフレーム１２ｂには座椅子２２が折り畳み可能に取り付けられ、さらに連結フレーム１３には、左右のフレーム体１２間に、背もたれ板２３が取り付けられている。そして、歩行車１０を歩行用に使用する場合には座椅子２２を縦に折り畳み、椅子として使用する場合には水平位置に倒されるものである。   Further, a seat chair 22 is foldably attached to the pair of left and right front frames 12 b, and a backrest plate 23 is attached to the connecting frame 13 between the left and right frame bodies 12. When the walking car 10 is used for walking, the seat 22 is folded vertically, and when it is used as a chair, it is brought down to a horizontal position.

次に、人が歩行車１０を用いて歩行するときの歩行車１０の動作を図３、図４を用いて説明する。人が車体後方から左右一対のハンドル１４を握って歩行車１０を前方に押し出すと、車台の前後輪２０，２４が回転して車台は前進し、人は車台に付いて歩行移動する。車体が前進すると、左右のハンドル１４は、後輪２０の回転運動によって往復運動する連結棒１８のクランク動作によって、交互に前後動する。   Next, the operation of the walking vehicle 10 when a person walks using the walking vehicle 10 will be described with reference to FIGS. When a person grasps the pair of left and right handles 14 from the rear of the vehicle body and pushes the walking vehicle 10 forward, the front and rear wheels 20 and 24 of the chassis rotate, the chassis moves forward, and the person walks and moves on the chassis. When the vehicle body moves forward, the left and right handles 14 move back and forth alternately by the crank operation of the connecting rod 18 that reciprocates by the rotational movement of the rear wheel 20.

このとき、左右の連結棒１８は、互いに後輪２０の回動角に対して相対的に１８０°位相がずれて連結されているので、左側のハンドル１４が後方にあるときは右側のハンドルは前方にあり（図３（ａ）、図４（ａ））、逆に左側のハンドル１４が前方にあるときは右側のハンドルは後方にある（図３（ｂ）、図４（ｂ））。   At this time, since the left and right connecting rods 18 are connected to each other with a 180 ° phase shift relative to the rotation angle of the rear wheel 20, when the left handle 14 is rearward, the right handle is When the left handle 14 is in front, the right handle is in the rear (FIGS. 3 (b) and 4 (b)).

人が歩行するときは腕の動きは足の動きに連動するが、後輪２０が１回転するとスライダ１４が１往復する。従って、後輪２０の円周の半分が歩行車１０を押す人の歩幅と等しければ、足の動きと手の動きが同期する。但し、手のリハビリを兼ねて歩行車１０を押す場合は、足の動きに対してスライダ１４は遅いもので良い。   When a person walks, the movement of the arm is linked to the movement of the foot, but when the rear wheel 20 makes one revolution, the slider 14 reciprocates once. Therefore, if the half of the circumference of the rear wheel 20 is equal to the stride of the person pushing the walking vehicle 10, the movement of the foot and the movement of the hand are synchronized. However, when pushing the walking vehicle 10 also for hand rehabilitation, the slider 14 may be slow with respect to the movement of the foot.

この実施形態の歩行車１０によれば、左右一対のハンドル１４が互いに１８０度位相がずれて往復移動するので、健常者が歩行する際に左右の腕を交互に動かしているのと同じ状態の腕の運動を行うことができる。さらに、サイドフレーム１２ｃは下方に向かってやや湾曲した形状であるので、スライダ１６の動きがスムーズである。しかも、健常者が自然体で歩行する腕の動きと同じようにハンドル１４が移動するので、歩行車１０を用いた歩行においても、体全体の重心移動やバランス感覚を取り戻すために効果的なリハビリを行うことができる。   According to the walking vehicle 10 of this embodiment, the pair of left and right handles 14 reciprocate with a phase difference of 180 degrees from each other. Therefore, when the healthy person walks, the left and right arms are moved alternately. Can exercise arms. Further, since the side frame 12c has a slightly curved shape toward the lower side, the movement of the slider 16 is smooth. Moreover, since the handle 14 is moved in the same manner as the arm movement when a healthy person walks naturally, even in walking using the walking car 10, effective rehabilitation can be performed to restore the movement of the center of gravity and the sense of balance of the entire body. It can be carried out.

また、後輪２０はハンドル１４と連動して、相対的に手の振りが足の移動と比較して遅くなるように設定することで、歩行車が前進するスピードが速すぎて体のバランスを失って転倒するなどの事故が起こる心配もなく安全である。   In addition, the rear wheel 20 is interlocked with the handle 14 so that the swing of the hand is relatively slow compared to the movement of the foot, so that the speed at which the walking vehicle moves forward is too fast and the balance of the body is increased. It is safe without worrying about accidents such as losing and falling.

また、図５に示すように、歩行車１０は、縦に折り畳まれた座椅子２２を水平位置に倒せば、背もたれ２３と座椅子２２によって構成される座席が現れる。例えば歩行訓練中の休憩場所として、あるいは簡易式の車椅子として使用することができる。   In addition, as shown in FIG. 5, in the walking vehicle 10, when the seat chair 22 folded vertically is brought down to a horizontal position, a seat constituted by the backrest 23 and the seat chair 22 appears. For example, it can be used as a resting place during walking training or as a simple wheelchair.

さらに、歩行車１０によれば、手押し状態で容易に腕を動かすことができ、腕の機能回復を早める。また、腕の動きは足の動きに連動するので、進行方向に腕を動かしているのと同様の状態となり、リハビリ効果も高いものである。また、正常な歩行動作に近づける歩行介助となる。さらに、歩行の際、体幹の回旋の動きがみられない多くの高齢者、軽度のパーキンソン病の患者等の歩行訓練として、そして日常の生活の中でも安全に利用できる。   Furthermore, according to the walking vehicle 10, the arm can be easily moved while being pushed by hand, and the function recovery of the arm is accelerated. In addition, since the movement of the arm is linked to the movement of the foot, the state is the same as when the arm is moved in the traveling direction, and the rehabilitation effect is high. Moreover, it becomes a walking assistance approaching normal walking motion. Furthermore, when walking, it can be used safely as walking training for many elderly people who do not see the rotation of the trunk, patients with mild Parkinson's disease, and even in daily life.

なお、この発明の歩行車は上記実施形態に限定されるものではなく、前輪及び後輪の大きさは、適宜選択可能なものである。また、座席の大きさに合わせて、各フレームや車輪などのサイズは適宜設定可能なものである。また、車台を構成する左右のフレーム体の構造は、スライダが前後に往復運動できる略水平な部分を有していればよく、一般的な三角フレーム構造やダイヤモンドフレーム構造（２つの三角形を合体させたダイヤ型）など、人を支えるのに十分な強度を備えた構造であれば特に限定しない。また、フレームの素材や座席を形成する素材など適宜選択可能である。   In addition, the walking vehicle of this invention is not limited to the said embodiment, The magnitude | size of a front wheel and a rear wheel can be selected suitably. Also, the size of each frame, wheel, etc. can be set as appropriate according to the size of the seat. In addition, the structure of the left and right frame bodies constituting the chassis only needs to have a substantially horizontal portion in which the slider can reciprocate back and forth, and a general triangular frame structure or a diamond frame structure (two triangles are combined). If the structure has sufficient strength to support a person, such as a diamond type), there is no particular limitation. Further, the material of the frame and the material forming the seat can be appropriately selected.
