Description

本考案は被介護者自身が手動操作により走行操作することも可能な介護用車椅子に関するものである。       The present invention relates to a care wheelchair that can be operated by a cared person by manual operation.

従来の介護用車椅子で人力型のものは、左右後輪の駆動輪の外側に同軸設けられた小径のハンドリムを直接、両手で回転させて駆動させるのが一般的であった。       Conventionally, a human-powered wheelchair for nursing care is generally driven by rotating a small-diameter hand rim coaxially provided on the outer sides of the driving wheels of the left and right rear wheels with both hands.

特許第3831907号Japanese Patent No. 3831907 実登第3125178号Mito No. 3125178

従来の介護用車椅子では、大径の駆動輪が内側にあり外側に同軸設けられた小径のハンドリムを手動で回転させるため、肘とか袖口が駆動輪に接することがあり、操作性の面で十分なものでは無かった。
また、これらの改善品として介護用車椅子本体の前方に垂直方向に回転させる手動ハンドルを設け、前輪を駆動する車椅子が公表されているが、介護者の乗降が不便で、多くの構成部品を必要としている。
In conventional wheelchairs for nursing care, a large-diameter drive wheel is on the inside and a small-diameter hand rim that is coaxially provided on the outside is manually rotated, so the elbow or cuff may contact the drive wheel, which is sufficient in terms of operability. It wasn't something.
In addition, a wheelchair that drives the front wheels by providing a manual handle that rotates vertically in front of the nursing wheelchair body as an improved product has been announced, but it is inconvenient for a caregiver to get on and off and requires many components. It is said.

本考案は、座席後部に手押しハンドルを、前後部に左右一対の前輪および後輪を備えた介護用車椅子において、車体フレームの前部に水平に設けた左右一対のハンドル座の上に水平方向に回転する左右一対の手動回転ハンドル備え、右側の手動回転ハンドルは右回転とし、左側の手動回転ハンドルは左回転とし、前記左右一対の手動回転ハンドルの回転駆動力を、ギアーボックス内のギアーを介してフレキシブルシャフトにより左右それぞれの後輪に伝達する構成としている。
そして、介護者の乗降を容易にするため、車体フレームの前部に水平に設けた左右一対のハンドル座は、左右方向に90度回転させることができ、乗降時の出入り口スペースを広くすることができるようにしてある。
The present invention is a nursing wheelchair equipped with a push handle at the rear of the seat and a pair of left and right front and rear wheels at the front and rear, and horizontally on a pair of left and right handle seats provided horizontally at the front of the body frame. A pair of left and right manual rotation handles are provided, the right manual rotation handle is set to the right rotation, the left manual rotation handle is set to the left rotation, and the rotational driving force of the pair of left and right manual rotation handles is transmitted via the gears in the gear box. In addition, it is configured to transmit to the left and right rear wheels by a flexible shaft.
And in order to make it easy for a caregiver to get on and off, the pair of left and right handle seats provided horizontally at the front part of the body frame can be rotated 90 degrees in the left and right direction, and the entrance / exit space for getting on and off can be widened. I can do it.

車椅子本体の前方の回転手道ハンドルで駆動できるので、肘とか袖口が駆動輪に接することがなく、フレキシブルシャフトを使用して回転手動ハンドルの駆動力を後輪に伝達しているので構造が単純化され、多くの構成部品を必要としない。
Since it can be driven by the rotating handway handle in front of the wheelchair body, the elbow or cuff does not touch the driving wheel, and the driving force of the rotating manual handle is transmitted to the rear wheel using a flexible shaft, so the structure is simple And does not require many components.

本考案の介護用車椅子は、座席後部に手押しハンドルを有し、後輪の左右に大径の駆動輪を前輪の左右に小径で全方向に回転可能なキャスターを備え、車体フレームにより車椅子全体を支えるている。車体フレームの前部に水平に設けた左右一対のハンドル座を取り付け、その上に水平方向に回転する左右一対の手動回転ハンドル備えている。右側の手動回転ハンドルは右回転とし、左側の手動回転ハンドルは左回転とし、前記左右一対の手動回転ハンドルの回転駆動力をギアーボックス内のギアーを介してフレキシブルシャフトにより左右それぞれの後輪に連結し、駆動力を伝達する構成としている。
そして、介護者の乗降を容易にするため、車体フレームの前部に水平に設けた左右一対のハンドル座は、左右方向に90度回転させることができ、乗降時の出入り口スペースを広くすることができるようにしてある。
The nursing wheelchair of the present invention has a push handle at the rear of the seat, a large-diameter driving wheel on the left and right of the rear wheel, and a caster that can rotate in all directions with a small diameter on the left and right of the front wheel. I support. A pair of left and right handle seats provided horizontally are attached to the front portion of the vehicle body frame, and a pair of left and right manual rotation handles that rotate horizontally are provided thereon. The right hand rotation handle is set to the right rotation, the left manual rotation handle is set to the left rotation, and the rotational driving force of the pair of left and right manual rotation handles is connected to the left and right rear wheels by the flexible shaft via the gears in the gear box. The driving force is transmitted.
And in order to make it easy for a caregiver to get on and off, the pair of left and right handle seats provided horizontally at the front part of the body frame can be rotated 90 degrees in the left and right direction, and the entrance / exit space for getting on and off can be widened. I can do it.

以下、添付図面に従って一実施例を説明する。
1は介護用車椅子で、左右の大径の後輪4とこれらと同軸に直結されたハンドリム10、左右の小径の前輪3、車椅子全体を支える車体フレーム5で構成されている。2は手押しハンドルである。
6はハンドル座、7は手動回転ハンドル、9はギアーボックスで前記ハンドル座6に取り付けられており、このギアーボックス9内で手動回転ハンドル7とフレキシブルシャフト8は夫々に直結した2つの歯車を介して接合されている。手動回転ハンドル7が右回転するとフレキシブルシャフト8は左回転し、手動回転ハンドル7の回転数と後輪4の回転数の比率は歯車のギアー比率により選択できる。
左右のハンドル座6は介護者が車椅子への乗降を容易にするため、左右の90度上方へ回転できる構造としている。
右側の手動回転ハンドル7と右側の後輪4が、左側の手動回転ハンドル7と左側の後輪4が、夫々フレキシブルシャフト8で接続されている。左右の手動回転ハンドル7は夫々単独で回転させることができ、夫々右回転、左回転させる事ができる。右側の手動回転ハンドル7を右回転させれば後輪4は前進方向に、左回転させれば後輪4は後進方向に回転する。同様に左側の手動回転ハンドル7を左回転させれば後輪4は前進方向に、右回転させれば後輪4は後進方向に回転する。即ち、左右それぞれの手動回転ハンドル7を夫々、同時に左右回転させれば左右それぞれの後輪4は前進方向に回転し介護用車椅子1は前進する。左側の手動回転ハンドル7を固定し右側の手動回転ハンドル7を右回転すれば左方向に回転することができ、同様に右側の手動回転ハンドル7を固定し左側の手動回転ハンドル7を左回転すれば右方向に回転することができる。

Hereinafter, an embodiment will be described with reference to the accompanying drawings.
Reference numeral 1 denotes a nursing wheelchair, which includes left and right large-diameter rear wheels 4, a hand rim 10 directly connected coaxially thereto, left and right small-diameter front wheels 3, and a body frame 5 that supports the entire wheelchair. Reference numeral 2 denotes a push handle.
6 is a handle seat, 7 is a manual rotation handle, and 9 is a gear box, which is attached to the handle seat 6. In this gear box 9, the manual rotation handle 7 and the flexible shaft 8 are connected via two gears directly connected to each other. Are joined. When the manual rotation handle 7 rotates to the right, the flexible shaft 8 rotates counterclockwise, and the ratio between the rotation speed of the manual rotation handle 7 and the rotation speed of the rear wheel 4 can be selected according to the gear ratio of the gear.
The left and right handle seats 6 are structured such that the caregiver can rotate 90 degrees upward to the left and right to facilitate getting on and off the wheelchair.
The right manual rotation handle 7 and the right rear wheel 4 are connected by a flexible shaft 8 to the left manual rotation handle 7 and the left rear wheel 4, respectively. The left and right manual rotation handles 7 can be independently rotated, and can be rotated right and left, respectively. If the right hand rotating handle 7 is rotated to the right, the rear wheel 4 rotates in the forward direction, and if it is rotated counterclockwise, the rear wheel 4 rotates in the backward direction. Similarly, if the left manual rotation handle 7 is rotated counterclockwise, the rear wheel 4 rotates in the forward direction, and if it rotates clockwise, the rear wheel 4 rotates in the reverse direction. That is, if the left and right manual rotation handles 7 are rotated to the left and right at the same time, the left and right rear wheels 4 rotate in the forward direction and the care wheelchair 1 moves forward. If the left manual rotation handle 7 is fixed and the right manual rotation handle 7 is rotated to the right, it can be rotated to the left. Similarly, the right manual rotation handle 7 is fixed and the left manual rotation handle 7 is rotated counterclockwise. Can be rotated to the right.
