Description

本考案は、着座した要支援者を移動できるように構成された車椅子に関するものであって、特に、移乗援助に適した車椅子に関する。   The present invention relates to a wheelchair configured to be able to move a person who needs to be seated, and more particularly to a wheelchair suitable for transfer assistance.

医療施設や介護施設においては、歩行移動が困難な要支援者が少なくなく、そのような要支援者を移動させる際に、車椅子が広く用いられている。
従来の車椅子は、複数の車輪を、走行方向が固定された固定輪若しくは走行方向が自在に変化する構造を持つ可動輪(例えば下記特許文献1参照)又はそれらの組合せ(例えば下記特許文献2参照)という形で備えているが、車輪の構成によって、様々な利点と欠点が生じる。
In medical facilities and nursing care facilities, there are not a few supporters who need difficulty walking, and wheelchairs are widely used to move such supporters.
A conventional wheelchair has a plurality of wheels, a fixed wheel with a fixed traveling direction, a movable wheel having a structure in which the traveling direction is freely changed (for example, see Patent Document 1 below) or a combination thereof (for example, see Patent Document 2 below). ), But there are various advantages and disadvantages depending on the wheel configuration.

特開2005−13445号公報JP 2005-13445 A 実用新案登録第3192528号公報Utility Model Registration No. 3192528

例えば、固定輪のみの車椅子は、方向転換の際に車椅子の向きを強制的にずらす必要があるという欠点があるものの走行時及び静止時の姿勢が安定するという利点がある。また、可動輪のみの車椅子は、走行時及び静止時の姿勢が比較的不安定であるという欠点があるものの、小回りが利き狭所において機動性があるという利点がある。固定輪と可動輪を組み合わせた車椅子は、両者の利点と欠点をバランスよく補う利点はあるものの、両者の欠点も併せ持つという欠点がある。   For example, a wheelchair with only a fixed wheel has an advantage that the posture at the time of running and at a standstill is stabilized although there is a disadvantage that the direction of the wheelchair must be forcibly shifted when changing the direction. In addition, a wheelchair with only movable wheels has a disadvantage that the posture at the time of traveling and stationary is relatively unstable, but has an advantage that it has a small turn and has mobility in a narrow space. A wheelchair that combines a fixed wheel and a movable wheel has an advantage of balancing both advantages and disadvantages in a well-balanced manner, but has the disadvantage of having both disadvantages.

特に、自宅などの比較的狭い施設による援助に用いる際、車椅子は、走行時の安定性よりも、むしろ静止時の安定性と小回りに重きを置かれることがほとんどである。
例えば、一般家屋のトイレにおいて、要支援者を便座に移乗させる場合などは、車椅子の脚部に前記可動輪のみを付設してトイレ内における良好な回転性能を獲得することが便宜であるが、前記可動輪のみを付設した構成は却って静止時における不安定を招来し、要支援者一人に対し支援者一人が対応したのでは、車椅子が様々な向きに移動することによって要支援者及び支援者双方の負担となるばかりか、落下・転倒の虞も高くなる。
一方、車輪の一部を固定輪としても、車椅子が様々な向きに移動する程度は弱まるものの、狭いトイレの中で小半径での回転が困難となり要支援者の移動自体が不可能となる場合もある。
In particular, when used for assistance in a relatively small facility such as a home, a wheelchair is mostly placed on stability at a standstill and a small turn rather than stability at the time of traveling.
For example, in a toilet of a general house, when transferring a person who needs support to a toilet seat, it is convenient to obtain a good rotation performance in the toilet by attaching only the movable wheel to the leg of the wheelchair, On the other hand, the configuration with only the movable wheels leads to instability at rest, and if one supporter responds to one supporter, the supporter and the supporter are required by moving the wheelchair in various directions. Not only will it be a burden on both sides, but the risk of falling or falling will also increase.
On the other hand, even if some of the wheels are fixed wheels, the wheelchair will move to various directions, but it will be difficult to rotate with a small radius in a narrow toilet, making it impossible for the supporter to move. There is also.

また、被支援者を便座や他の椅子などに移乗させるには、移乗先の高さに合わせて座面を昇降する必要性も高いことに加え、人を座らせた状態で移動させる際の安全性を確保する肘掛も被支援者の移乗の妨げとなる。
以上の様に、座面の昇降、肘掛の退避、静止時の安定及び狭所での回転性の全てを満足する車椅子が要請されているものの、その達成は、前記各機能個々の作用が相互に妨げとなっていることもあって極めて困難であった。
In addition, in order to transfer the supportee to a toilet seat or other chair, it is highly necessary to move the seat up and down according to the height of the transfer destination, and in addition to moving the person while sitting down The armrest that secures safety also hinders the supportee's transfer.
As described above, although there is a demand for a wheelchair that satisfies all of the lifting and lowering of the seating surface, the retraction of the armrest, the stability at rest and the rotation in the narrow space, the achievement of the respective functions is mutually achieved. It was extremely difficult because of the obstacles.

本考案は、上記実情に鑑みてなされたものであって、座面の昇降、肘掛の退避、静止時の安定及び狭所での回転性の全てを満足する車椅子の提供を目的とする。   The present invention has been made in view of the above circumstances, and an object of the present invention is to provide a wheelchair that satisfies all of elevating and lowering of a seating surface, retraction of an armrest, stability at rest, and rotation in a narrow space.

上記課題を解決するためになされた本考案による車椅子は、座席、背もたれ及び肘掛を具備する水平回転可能な椅子本体と、前記椅子本体を走行可能に起立させる脚部と、被支援者の移乗を容易化する移乗支援手段を備え、前記移乗支援手段は、前記前方向輪に対して前記座席の位置を上下させる昇降手段と、被支援者の移乗方向から前記肘掛を撤去し復帰させる肘掛退避手段と、前記椅子本体の回転を制止する回転規制手段と、前記脚部の走行を規制する制動手段とを備えることを特徴とする。   A wheelchair according to the present invention, which has been made to solve the above-mentioned problems, has a horizontally rotatable chair body having a seat, a backrest and an armrest, a leg part for standing up so that the chair body can run, and transfer of a supportee. The transfer support means includes an elevating means for raising and lowering the position of the seat with respect to the front wheel, and an armrest retracting means for removing and returning the armrest from the transfer direction of the person being supported. And a rotation restricting means for restricting the rotation of the chair body and a braking means for restricting the travel of the leg.

前記肘掛退避手段による前記肘掛の退避操作で前記椅子本体の回転を制止する回転規制手段を備える構成や、前記肘掛退避手段による前記肘掛の退避操作で前記脚部の走行を規制する制動手段を備える構成を採用することができる。   A structure including a rotation restricting means for restricting the rotation of the chair main body by the retracting operation of the armrest by the armrest retracting means, or a braking means for restricting the travel of the leg by the retracting operation of the armrest by the armrest retracting means. A configuration can be employed.

また、前記椅子本体の水平回転において、前記椅子本体の向きと前記脚部の進行方向とが一致する向きでクリック感を生じさせる回転クリック機構を備える構成とすることもできる。   Further, in the horizontal rotation of the chair main body, a rotation click mechanism that generates a click feeling in a direction in which the direction of the chair main body and the traveling direction of the leg portion coincide with each other may be provided.

本考案による車椅子によれば、被支援者の方向転換を、例えば、自宅のトイレといった狭所にあっても良好に実施することができる他、前記移乗支援手段を備える構成によって、***、入浴、食事または診察などの際に、トイレ、支援機器、食堂またはベッドなどへ、被支援者・支援者にとって負担無く移乗させることが可能となる。   According to the wheelchair according to the present invention, the direction of the supportee can be favorably implemented even in a confined space such as a toilet at home, and excretion, bathing, During meals or medical examinations, it becomes possible to transfer to a restroom, support equipment, canteen or bed without any burden on the supportee / supporter.

また、前記肘掛退避手段による前記肘掛の退避操作で前記椅子本体の回転を制止する回転規制手段を備える構成や、前記肘掛退避手段による前記肘掛の退避操作で前記脚部の走行を規制する制動手段を備えることによって、移乗作業に要する操作が緩和される他、このように、移乗に便宜な操作を回転規制操作や制動操作といった安全措置に直結させた構成を採ることによって、安全措置の懈怠等に伴う移乗時における事故も減少させることができる。   Further, a configuration including a rotation restricting means for restricting the rotation of the chair main body by the retracting operation of the armrest by the armrest retracting means, or a braking means for restricting the travel of the leg by the retracting operation of the armrest by the armrest retracting means. In addition to alleviating the operations required for the transfer work, it is possible to reduce the safety measures by adopting a configuration in which the operations convenient for the transfer are directly connected to the safety measures such as the rotation restricting operation and the braking operation. Accidents at the time of transfer can be reduced.

更に、前記椅子本体の水平回転において、前記椅子本体の向きと前記脚部の進行方向とが一致する向きでクリック感を生じさせる回転クリック機構を備えることによって、車椅子の移動が円滑且つ容易となる様に定められた方向と、前記椅子本体の向きを、容易に一致させることが可能となる。
尚、前記椅子本体の向きと前記脚部の後退方向やそれに対し直交する方向とが一致する向き、又は前記椅子本体の回転を等分割する形でクリック感を生じさせる構成としてもよい。
Furthermore, in the horizontal rotation of the chair body, the wheelchair can be moved smoothly and easily by providing a rotation click mechanism that generates a click feeling in a direction in which the direction of the chair body coincides with the traveling direction of the legs. It is possible to easily match the direction determined in this way with the direction of the chair body.
In addition, it is good also as a structure which produces a click feeling in the direction which the direction of the said chair main body and the retraction direction of the said leg part, and the direction orthogonal to it correspond, or the form which divides | segments the rotation of the said chair main body equally.

以下、本考案による車椅子の実施の形態を図面に基づき詳細に説明する。
図1に示す車椅子は、水平回転可能な椅子本体1と、前記椅子本体1を走行可能に起立させる脚部2と、被支援者の移乗を容易化する移乗支援手段を備えたものである。
Hereinafter, embodiments of a wheelchair according to the present invention will be described in detail with reference to the drawings.
The wheelchair shown in FIG. 1 is provided with a chair body 1 that can be rotated horizontally, a leg portion 2 that stands up so that the chair body 1 can run, and a transfer support means that facilitates transfer of the person being supported.

この例の前記椅子本体1は、被支援者が腰を降ろす座席4、腰を降ろした被支援者がその背を預ける背もたれ5と、腰を降ろした被支援者がその腕を預ける肘掛3を具備する。
この例においては、前記座席4、前記背もたれ5及び前記肘掛3は、それぞれ当該椅子本体1の基部に支持されている。それらには、支援者が操作するハンドル6が支持されていてもよい(図6参照)。
この例の前記脚部2は、走行性能を有する車両部27と当該車両部27の中央部から起立する支柱28とで構成され、前記車両部27に、当該車椅子の進行方向を変える操舵輪7と、回転軸の向きが固定された固定輪8を備えるが、図5乃至図7に示す例のように、前記脚部2を走行可能とする車輪として操舵輪7のみを用いてもよい。
The chair body 1 in this example includes a seat 4 on which the supportee sits down, a backrest 5 on which the supportee who has lowered his / her back entrusts his back, and an armrest 3 on which the supportee who has lowered his / her back entrusts his / her arm. It has.
In this example, the seat 4, the backrest 5, and the armrest 3 are each supported by a base portion of the chair body 1. They may be supported by a handle 6 operated by a supporter (see FIG. 6).
The leg portion 2 in this example is composed of a vehicle portion 27 having running performance and a support column 28 that stands up from the center portion of the vehicle portion 27, and the steering wheel 7 that changes the traveling direction of the wheelchair on the vehicle portion 27. However, as in the example shown in FIGS. 5 to 7, only the steering wheel 7 may be used as a wheel that allows the leg portion 2 to travel.

前記移乗支援手段は、前記前輪(当該例では前記操舵輪7)に対して前記座席4の位置を上下させる昇降手段9と、被支援者の移乗方向から前記肘掛3を撤去し復帰させる肘掛退避手段10と、前記椅子本体1の回転を制止する回転規制手段11と、前記脚部2の走行を規制する制動手段とを備える。
これら各手段の動作を適宜調整できる構成が採られていることによって、当該車椅子から種々の設備への移乗の便宜と安全が確保される。
The transfer support means includes an elevating means 9 for raising and lowering the position of the seat 4 with respect to the front wheel (the steering wheel 7 in this example), and an armrest retreat for removing and returning the armrest 3 from the transfer direction of the person being supported. Means 10, rotation restriction means 11 for restricting rotation of the chair body 1, and braking means for restricting travel of the leg 2.
By adopting a configuration in which the operation of each means can be adjusted as appropriate, the convenience and safety of transfer from the wheelchair to various facilities are ensured.

この車椅子の例は、前記脚部2に対する前記椅子本体1の水平回転において、前記椅子本体1の向きと前記脚部2の進行方向とが一致する向きに至った時(その水平回転範囲360度を等分割した複数箇所に当該向きを含めることもできる)に、その都度クリック作用(クリック音又はクリック感などの発生)を生じさせる回転クリック機構(例えば特開2014−160597号公報参照)を備える。   In this wheelchair example, in the horizontal rotation of the chair body 1 with respect to the leg 2, when the direction of the chair body 1 coincides with the traveling direction of the leg 2 (the horizontal rotation range is 360 degrees). A rotation click mechanism (see, for example, Japanese Patent Application Laid-Open No. 2014-160597) that causes a click action (occurrence of a click sound or a click feeling) in each case. .

当該回転クリック機構の存在によって、前記脚部2に対する前記椅子本体1の向きが、移乗の便宜で如何様に回転させられたとしても、当該車椅子が走行する際には、容易に前記椅子本体1を前記脚部2の走行方向と一致させることができる。
尚、前記走行方向とは、支援者が前記車椅子のハンドル6等を介して当該車椅子を最も安定した状態で操作し得る向きと車輪7,8の方向が一致する範囲であって、この例の場合には、当該範囲の中間方向に設定されている。
Even if the orientation of the chair body 1 with respect to the leg 2 is rotated for convenience of transfer due to the presence of the rotation click mechanism, the chair body 1 can be easily moved when the wheelchair travels. Can be made to coincide with the traveling direction of the leg 2.
The traveling direction is a range in which the direction in which the supporter can operate the wheelchair in the most stable state via the handle 6 of the wheelchair and the direction of the wheels 7 and 8 coincide. In this case, it is set in the middle direction of the range.

また、この車椅子の例は、前記椅子本体1の全体を前記操舵輪7又は固定輪8に対して上下させる前記昇降手段9を備える。
前記昇降手段9は、如何なる構造を採ってもよい。例えば、気圧を用いた伸縮シリンダなどによる寸法調整可能な緩衝機構と、スプリング12による伸展作用及び収縮作用を利用した復元機構を併用するなどの手法がある。
In addition, the example of the wheelchair includes the elevating means 9 that moves the entire chair body 1 up and down with respect to the steering wheel 7 or the fixed wheel 8.
The lifting means 9 may take any structure. For example, there is a technique in which a buffer mechanism capable of adjusting dimensions by an expansion / contraction cylinder using atmospheric pressure and a restoring mechanism using an extension action and a contraction action by a spring 12 are used in combination.

即ち、座席4を下方へ加圧し、同時にレバー23等の操作でシリンダ13内を排気することによって寸法を縮め、スプリング12により伸縮シリンダを伸展しシリンダ13内へ給気することによって寸法を伸ばし、給排気を止めることによって寸法を維持しつつスプリング12と気圧によって緩衝機能を得る手法である。
給気及び排気を可能とする構成は、例えば、レバー操作によってシリンダ13内外の通気路14を開閉する構造を採用する。
That is, the size is reduced by pressurizing the seat 4 downward and simultaneously exhausting the inside of the cylinder 13 by operating the lever 23 or the like, and the size is extended by extending the telescopic cylinder by the spring 12 and supplying air into the cylinder 13. This is a technique for obtaining a buffer function by the spring 12 and the atmospheric pressure while maintaining the dimensions by stopping the supply and exhaust.
As a configuration that enables air supply and exhaust, for example, a structure that opens and closes the air passage 14 inside and outside the cylinder 13 by lever operation is adopted.

この例の前記肘掛3は、前記座席4の下部に、側方へ水平に突出する形で軸支された支軸18で回転可能となるように前記椅子本体1の基部15に固定されている。
この例の前記肘掛退避手段10は、左右の前記肘掛3,3がそれぞれ個別に後方又は前方へ回転し、被支援者の移乗方向から前記肘掛3を撤去し復帰させる回転機構16を備えると共に、少なくとも前記肘掛3として機能する際にその回転を禁止する回転ロック機構17を備える。
The armrest 3 in this example is fixed to the base portion 15 of the chair body 1 so as to be rotatable at a lower portion of the seat 4 by a support shaft 18 pivotally supported so as to protrude horizontally to the side. .
The armrest retracting means 10 of this example includes a rotation mechanism 16 that causes the left and right armrests 3 and 3 to individually rotate rearward or forward, and remove and return the armrest 3 from the transfer direction of the person being supported, At least a rotation lock mechanism 17 that prohibits rotation when functioning as the armrest 3 is provided.

前記回転機構16は、その回転域として、前記肘掛3が略水平となる位相から、当該肘掛3が被支援者の横移動の支障とならない位置に退避できる位相に至る回転量とすることを要し、その回転方向としては、回転量の面及び安全面に照らして後方回転が望ましい。
尚、前記肘掛3を移乗方向から退避させる手法として、使用される施設によっては、前記椅子本体1の後方へ平行移動する手法を採ることもできる。
The rotation mechanism 16 needs to have a rotation amount ranging from a phase where the armrest 3 is substantially horizontal to a phase where the armrest 3 can be retracted to a position where it does not hinder the lateral movement of the supportee. As the rotation direction, it is desirable to rotate backward in view of the amount of rotation and safety.
In addition, as a method of retracting the armrest 3 from the transfer direction, a method of translating backward to the chair body 1 can be adopted depending on the facility used.

前記回転規制手段11は、前記椅子本体1と共に水平回転するロッド(例えば、前記シリンダ13のピストンロッド19などの延長線上に回転自在に支持されるもの)に、当該ロッドと共に回転するディスク20又はドラム21を固着し、当該ディスク20又はドラム21をブレーキ操作によって挟持又は加圧し、その状態を維持又は解除できる所謂ディスクブレーキ機構や所謂ドラムブレーキなどの手法から適宜採用すればよい。   The rotation restricting means 11 is a disc 20 or a drum that rotates together with the rod (for example, one that is rotatably supported on an extension line such as the piston rod 19 of the cylinder 13) that rotates horizontally with the chair body 1. The disc 20 or the drum 21 may be clamped or pressed by a brake operation, and a state such as a so-called disc brake mechanism or a so-called drum brake may be used as appropriate.

当該回転規制手段11は、レバー操作で起動する既存の手法が存在するが、この例では、前記レバー操作に替えて前記肘掛3の操作を前記回転規制手段11の稼動操作として採用し、前記肘掛退避手段10による前記肘掛3の退避操作で前記椅子本体1の回転を制止し、当該肘掛3の復帰操作を経て前記回転ロック機構17が回転禁止位置を採った際に回転を再開する前記回転規制手段11とすることもできる。
この様な構造を採ることによって、前記椅子本体1を適切な高さで適切な向きに回転させた後に、前記肘掛3を退避させることによって、回転時における前記肘掛3と周囲構造物との緩衝を回避し、当該適切な向きに維持固定させることが可能となる。
The rotation restricting means 11 has an existing method that is activated by lever operation. In this example, instead of the lever operation, the operation of the armrest 3 is adopted as the operation operation of the rotation restricting means 11, and the armrest is The rotation restriction that stops the rotation of the chair body 1 by the retraction operation of the armrest 3 by the retraction means 10 and resumes the rotation when the rotation lock mechanism 17 takes the rotation prohibition position through the return operation of the armrest 3. Means 11 may be used.
By adopting such a structure, after the chair body 1 is rotated at an appropriate height and in an appropriate direction, the armrest 3 is retracted, thereby buffering the armrest 3 and the surrounding structure during rotation. Can be avoided and maintained and fixed in the appropriate orientation.

前記制動手段は、少なくとも前記固定輪8に対して既存の制動手法(例えば上記特許文献1又は上記特許文献2参照)による制動を行えばよい。
前記制動手段の操作は、例えば、前記肘掛退避手段10の退避操作又は、前記肘掛3や前記ハンドル6が備えるブレーキレバー29の操作でブレーキワイヤー等の制御条(帯状のものを含む)又は制御竿(以下「制御媒体30」という)の進退制御を行うことによって実現することができる。
The braking means may perform braking on at least the fixed wheel 8 by an existing braking method (for example, see Patent Document 1 or Patent Document 2).
The operation of the braking means is, for example, a retraction operation of the armrest retraction means 10 or a control lever (including a belt-like member) or a control rod such as a brake lever 29 provided on the armrest 3 or the handle 6. This can be realized by performing forward / backward control (hereinafter referred to as “control medium 30”).

前記肘掛3の退避操作で制動手段を機能させる場合の例として、前記肘掛3の退避操作に伴う前記支軸18の回転で前記制御媒体30を引き寄せ(当該例では巻き取り)又は解除することによる前記進退制御が挙げられる(図11及び図12参照)。
図に示す例では、前記制御媒体30は、前記支柱28の内部の中空部を経て前記脚部2に設けた制動手段又は前記回転規制手段11の制御竿に連結され、各々の機能を発揮することとなる。
前記椅子本体1と前記脚部2は水平回転可能な構造であるため前記制御媒体30の捻転が生じ得る。そこで、当該捻転による制動機能の障害を回避すべく、前記制御媒体30は、その中間に相互に回転可能な単数又は複数のカップリング部材31を付設すると共に、前記制御媒体30の軌道を安定させる誘導管や滑車等の案内手段32を付設することが望ましい。
As an example of the case where the braking means functions by the retracting operation of the armrest 3, the control medium 30 is pulled (taken up in this example) or released by the rotation of the support shaft 18 accompanying the retracting operation of the armrest 3. The advance / retreat control is exemplified (see FIGS. 11 and 12).
In the example shown in the figure, the control medium 30 is connected to a braking means provided on the leg 2 or a control rod of the rotation restricting means 11 through a hollow portion inside the support column 28 and exhibits each function. It will be.
Since the chair body 1 and the leg portion 2 are horizontally rotatable, the control medium 30 may be twisted. Therefore, in order to avoid the failure of the braking function due to the torsion, the control medium 30 is provided with one or a plurality of coupling members 31 that can rotate relative to each other and stabilize the trajectory of the control medium 30. It is desirable to provide guide means 32 such as a guide tube or a pulley.

上記手法以外にも、図1の例において、前記肘掛退避手段10の回転にラチェット機構を介在し、前記肘掛3の機能時(起立時)及び退避時(平伏時)それぞれの限界位置(例えば回転範囲の前後両端)において前記脚部2に対する前記椅子本体1の水平回転を禁止し(前記ラチェット機構にロックを掛け)、左右いずれかの前記肘掛3が中間位置にある場合において同水平回転を許可する(前記ラチェット機構のロックを解除する)構成を採ることによって、走行時及び移乗時における椅子本体1の向きを固定し、移乗準備における椅子本体1の向き調整時にのみ回転可能とすることができる。
前記椅子本体1の向きと前記脚部2の進行方向とが一致する向きである場合には、前記肘掛3又は肘掛フレーム22の一部を前記固定輪8に圧接させ、その回転を規制した状態でラチェット機構をロックする手法を採ることもできる(図4参照)。
In addition to the above method, in the example of FIG. 1, a ratchet mechanism is interposed in the rotation of the armrest retracting means 10, and the limit positions (for example, rotation) of the armrest 3 when it functions (when standing) and when retracted (when flat) Horizontal rotation of the chair body 1 with respect to the leg 2 at both the front and rear ends of the range is prohibited (the ratchet mechanism is locked), and the horizontal rotation is permitted when either the left or right armrest 3 is in an intermediate position. By adopting a configuration (to release the lock of the ratchet mechanism), it is possible to fix the orientation of the chair body 1 during traveling and transfer, and to rotate only when adjusting the orientation of the chair body 1 during transfer preparation. .
When the direction of the chair body 1 and the direction of travel of the leg portion 2 coincide with each other, the armrest 3 or a part of the armrest frame 22 is pressed against the fixed ring 8 and the rotation thereof is restricted. Thus, a method of locking the ratchet mechanism can be adopted (see FIG. 4).

前記肘掛3や前記ハンドル6が備えるブレーキレバー29の操作で制動手段を機能させる場合は、前記構成における前記支軸18による巻き取りに替えて、前記ブレーキレバー29による前記制御媒体30の進退制御を行う構成を採ることができる。
前記回転規制手段11にあっては、前記制動手段と同様に進退制御が為された前記制御媒体30を、前記回転規制手段11の制御竿(例えば図9又は図10参照)に連結することによって機能させることができる。
When operating the braking means by operating the brake lever 29 provided in the armrest 3 or the handle 6, the control medium 30 is controlled to advance and retreat by the brake lever 29 instead of winding by the support shaft 18 in the configuration. The configuration to be performed can be taken.
In the rotation restricting means 11, the control medium 30 that has been controlled to advance and retreat in the same manner as the braking means is connected to a control rod (for example, see FIG. 9 or FIG. 10) of the rotation restricting means 11. Can function.

この様に、前記回転規制手段11と同様に、前記肘掛退避手段10による前記肘掛3の退避操作で前記脚部2の走行を規制する制動手段となり、前記肘掛退避手段10と連動する前記回転規制手段11との組み合わせで、移乗時における椅子本体1の回転規制と車椅子の制動を、前記肘掛3の退避による移乗準備作業の終了と同時に一時に行うことが可能となる。   In this manner, similarly to the rotation restricting means 11, the rotation restricting means that acts as a braking means that restricts the travel of the leg 2 by the retracting operation of the armrest 3 by the armrest retracting means 10, and the rotation restriction interlocking with the armrest retracting means 10. In combination with the means 11, the rotation restriction of the chair body 1 and the wheelchair braking at the time of transfer can be performed at the same time as the end of the transfer preparation work by retracting the armrest 3.

この車椅子の例は、前記椅子本体1の基部から当該椅子本体1の前方下方に延びた足置き24を備える。
当該足置き24は、被支援者の膝の裏側から踵に至る長さより僅かに短いフレーム25の先端部に足台26を収納可能に備える。ここで、収納可能とは、例えば、前記フレーム25の向きに沿う様に上向きに折りたたむことができ、被支援者が足を置く際には、前記フレーム25の向きに対して略直角となるように当該足台26が展開できる構成を採ることを指す。
前記足置き24は、この様な構成を採り、前記椅子本体1が前記脚部2に対して回転する際において、当該足置き24と前記脚部2との間で干渉が生じない位置関係を採る構成を有する。
This example of the wheelchair includes a footrest 24 that extends from the base of the chair body 1 to the front lower side of the chair body 1.
The footrest 24 includes a footrest 26 that can be stored at the tip of a frame 25 that is slightly shorter than the length from the back side of the supportee's knee to the heel. Here, the storage is possible, for example, it can be folded upward along the direction of the frame 25, and when the person to be supported puts his / her foot, it is substantially perpendicular to the direction of the frame 25. In other words, this means that the footrest 26 can be deployed.
The footrest 24 employs such a configuration, and when the chair body 1 rotates with respect to the leg portion 2, the footrest 24 has a positional relationship in which no interference occurs between the footrest 24 and the leg portion 2. It has a configuration to adopt.
