Abstract

<P>PROBLEM TO BE SOLVED: To provide a wheelchair which is operated by a user to recline or to be completely horizontal to be a bed so that the user takes a rest without bending backward. <P>SOLUTION: A rear wheel moving rail 6 for moving a rear wheel back and forth is attached under a seat of the wheelchair, and the rear wheel is mounted by connecting a chain 8 to a rear wheel axle 9 to move the rear wheel in a manner that the rear wheel axle 9 is pulled back and forth by a rear wheel winding gear 7 and a rear wheel winding double gear 10. Sector-shaped, backrest connecting gear plates 3 which are directly coupled to a backrest 1 are provided on both sides of armrests 2. They are mounted in a manner that the backrest 1 is respectively actuated to be vertical and horizontal by a backrest moving triple gear 18. The double gear 10 and the triple gear 18 are connected by a chain 15. The wheelchair shows stability without bending backward when the wheelchair is converted to be reclined or to be a bed since the rear wheel 5 moves backward along an angle of reclining the backrest 1. <P>COPYRIGHT: (C)2007,JPO&INPIT

Description

この発明は車椅子に関する。  The present invention relates to a wheelchair.

従来の車椅子としては、車椅子とベットは別々のものであった。
リクライニングとしての車椅子も後ろへの反り返り防止として補助車が必要であった。As a conventional wheelchair, the wheelchair and the bed are different.
The reclining wheelchair also needed an auxiliary vehicle to prevent it from turning backward.

この発明は、従来の車椅子では長時間使用して患者が疲れを感じたときなどベットに乗り移って休憩をしていたが、この車椅子を使用することによってベットに乗り移らなくても自分で操作してリクライニングや完全に水平のベット状態にすることが出来、後ろに反り返ることなく安全に休憩が出来る。  In the present invention, a conventional wheelchair is used for a long time and the patient feels tired and changes to the bed to take a break. However, by using this wheelchair, the user can operate by himself without changing to the bed. Can be reclined or bet completely horizontal, and you can rest safely without bowing back.

ハンドル付巻き取り歯車１６は片方だけに設け、背もたれ移動用三連歯車１８にチェーン１７で連結する。
下肢部アーム１２は両側に設けられた下肢部アーム連結バー１４によって背もたれ連結歯車盤３に接続され背もたれを水平に倒したとき下肢部アーム連結バー１４によって下肢部アーム１２が水平になるように取り付る。
両側の後部車輪前後移動歯車１０の車軸は回転シャフト１１で連結された一体型とし、片一方に取り付けられたハンドル付巻き取り歯車１６を回転させる事で回転シャフト１１を回転させて反対側の後輪巻き取り用二連歯車１０を回転させる構造とするThe present invention will be described with reference to the drawings. As shown in FIG. 1, a rear wheel moving rail 6 on which a rear wheel can move back and forth is attached under a wheelchair seat, and the rear wheel of the wheelchair is The structure is movable, and a chain 8 is connected to the rear wheel axle 9 and attached so as to move in a form of being pulled back and forth by a rear wheel winding gear 7 and a rear wheel winding double gear 10.
On both sides of the armrest 2, there are provided fan-shaped back connection gear boards 3 that are directly connected to the back 1, and each is mounted so that the back can move vertically and horizontally by a triple gear 18 for moving the back, and a double gear for winding the rear wheel. 10 and the back-shifting triple gear 18 are connected by a chain 15.
The take-up gear 16 with a handle is provided only on one side, and is connected to a triple gear 18 for backrest movement by a chain 17.
The lower limb arm 12 is connected to the backrest connecting gear board 3 by the lower limb arm connecting bars 14 provided on both sides, and the lower limb arm connecting bar 14 is arranged so that the lower limb arm 12 is horizontal when the backrest is tilted horizontally. Attached.
The axles of the rear wheel front and rear moving gears 10 on both sides are integrated with a rotating shaft 11, and the rotating shaft 11 is rotated by rotating a winding gear 16 with a handle attached to one of the rear wheels. A structure in which the double gear 10 for ring winding is rotated.

この発明は以上説明したように従来の車椅子では長時間使用して患者が疲れを感じたときなどベットに乗り移って休憩をしていたが、この車椅子を使用することによってベットに乗り移らなくても自分で操作してリクライニングや完全に水平のベット状態にすることが出来、後ろに反り返ることなく安全に休憩が出来る  As described above, the conventional wheelchair is used for a long time to rest on the bed, such as when the patient feels tired, but without using the wheelchair, Can be operated by yourself to be reclined or fully leveled bet, so you can rest safely without bowing back

以上のように構成された、車イスで実際に車イス状態からベット及びリクライニングになるまでのシステムを説明する。
図１は車椅子の状態にある歯車式車椅子の側面図である。
片方のハンドル付巻き取り歯車１６を回転させることでチェーン１７で連結された背もたれ移動用三連歯車１８を回転させ、背もたれ移動用三連歯車１８は背もたれ連結歯車盤４を回転させて背もたれ１を水平方向に回転させると同時に、チェーン１５で連結された後輪巻き取り用二連歯車１０を回転させると共に背もたれ連結歯車盤３に接続された下肢部アーム連結バー１４によって下肢部アーム１２が水平方向に移動する、後輪巻き取り用二連歯車１０は後輪巻き取り用歯車７を介して取り付けられたチェーン８で車椅子の後輪車軸９を引っ張り後輪を後方へ移動させる。
後輪巻き取り用二連歯車１０の車軸は反対側の後輪巻き取り用二連歯車１０に連結された一体型の回転シャフト１１であり、反対側の後輪巻き取り用二連歯車１０を同時に回転させ反対側の後輪を後方へ移動させると共に連結されたチェーン１５で背もたれもを水平方向に移動させ、接続された下肢部アーム１２も水平方向に移動する
以上のように片方のハンドル付巻き取り歯車１６を回転させることで両側の後部車輪、背もたれ及び下肢部アームを操作出来る。
図４はリクライニング状態になった歯車式車椅子の側面図である、このとき後輪は後輪移動レール６の中間位置にある。
図５はベット状態になった歯車式車椅子の側面図である、このとき後輪は後輪移動レール６の最後方位置にある。
このように背もたれの倒れる角度に応じて後輪が後方に移動し前輪との車輪の幅を広げ反り返りを防止する。
元の車椅子に戻すにはハンドル付巻き取り歯車１６を逆回転させる事で背もたれ１を起こし下肢部アーム１２を折りたたみ後輪が前方に移動し前輪との車輪の幅を縮めて元の車椅子になる。A system configured as described above from the wheelchair state to the betting and reclining will be described.
FIG. 1 is a side view of a gear wheelchair in a wheelchair state.
By rotating one of the winding gears 16 with a handle, the backrest moving triple gear 18 connected by the chain 17 is rotated, and the backrest moving triple gear 18 rotates the backrest connecting gear board 4 to rotate the backrest 1. The lower limb arm 12 is horizontally rotated by the lower limb arm connecting bar 14 which rotates the rear wheel double gear 10 connected by the chain 15 and is connected to the backrest connecting gear board 3 at the same time as rotating in the horizontal direction. The rear-wheel winding double gear 10 that moves to the rear wheel pulls the rear wheel axle 9 of the wheelchair with the chain 8 attached via the rear-wheel winding gear 7 and moves the rear wheel rearward.
The axle of the double wheel 10 for winding the rear wheel is an integral rotary shaft 11 connected to the double gear 10 for winding the rear wheel on the opposite side. At the same time, the rear wheel on the opposite side is moved backward, the back 15 is moved in the horizontal direction by the connected chain 15, and the connected lower limb arm 12 is also moved in the horizontal direction. By rotating the winding gear 16, the rear wheels, the backrest, and the lower limb arms on both sides can be operated.
FIG. 4 is a side view of the gear wheelchair in the reclining state. At this time, the rear wheel is at an intermediate position of the rear wheel moving rail 6.
FIG. 5 is a side view of the wheeled wheelchair in the bet state. At this time, the rear wheel is at the rearmost position of the rear wheel moving rail 6.
In this way, the rear wheel moves rearward according to the angle at which the backrest falls, and the width of the wheel with the front wheel is widened to prevent warping.
To return to the original wheelchair, reversely rotate the winding gear 16 with the handle to raise the backrest 1 and fold the lower limb arm 12 so that the rear wheel moves forward and the width of the wheel with the front wheel is reduced to become the original wheelchair. .
