Description

本発明は、移動手段としての車輪を有する本体と、本体に取り付けられた椅子部を有しかつ横移動手段を有する車椅子に関するものである。   The present invention relates to a wheelchair having a main body having wheels as moving means and a chair portion attached to the main body and having lateral moving means.

高齢者や傷病者等の移動のために、車椅子の需要が増えており、構造上の改良も種々加えられつつある。車椅子は、当然のことながら椅子に坐ることができなければ利用することもできないので、そのような者に対しては台車付きのストレッチャーが適している。しかし坐ることはできるが歩くことができない、或いは立つことが困難であるという者もおり、車椅子利用者の幅は相当に広く、どこまでが車椅子利用に適するかというボーダーラインを明確に引くことはできない。   The demand for wheelchairs is increasing due to the movement of elderly people and victims, and various structural improvements are being added. Since a wheelchair cannot be used unless it can naturally be seated in a chair, a stretcher with a carriage is suitable for such a person. However, there are those who can sit but cannot walk or stand, and the width of wheelchair users is quite wide, and it is not possible to clearly draw the borderline to what extent is suitable for wheelchair use. Can not.

ストレッチャーないしはベッドのように平らな形態にも変換可能な構造を持つ車椅子も公知である。例えば特開平１１−３０９１７７号として公開されている発明は、数十センチメートル程度の空間でも利用者が車椅子から他の設備へ乗り移ることの困難さを解消するために、空間をできる限り狭くして利用者の乗り移りを容易かつ安全ならしめるという目的を有している。そのため同号の発明は、座部を有するフレームを車輪を有するフレームに対して左右方向へスライド可能とした構造を有している。   A wheelchair having a structure that can be converted into a flat form such as a stretcher or a bed is also known. For example, in the invention disclosed in Japanese Patent Laid-Open No. 11-309177, the space is made as small as possible in order to eliminate the difficulty of a user transferring from a wheelchair to another facility even in a space of about several tens of centimeters. The purpose is to make it easy and safe for users to transfer. For this reason, the invention of the same number has a structure in which a frame having a seat portion can be slid in the left-right direction with respect to a frame having wheels.

特開平１１−３０９１７７号JP-A-11-309177

本発明は前記の点に着目してなされたものであり、その課題は、利用者が全く歩かずかつ身体を自力で支えない状態でも、寝たままの姿勢で側方から乗り降りさせることができるように横移動手段を備えた車椅子を提供することである。また本発明の他の課題は、ベッドないしはストレッチャーなどとしても使用可能な車椅子を提供することである。   The present invention has been made paying attention to the above points, and the problem is that the user can get on and off from the side in a lying position even when the user does not walk at all and does not support the body by himself / herself. It is providing the wheelchair provided with the lateral movement means. Another object of the present invention is to provide a wheelchair that can be used as a bed or a stretcher.

前記の課題を解決するため本発明は、移動手段としての車輪を有する本体と、本体に取り付けられた椅子部を有する車椅子について、本体は、前、中、後３組の車輪を有しており、その内前後２組の車輪は任意の方向を向き得るキャスター輪、中間の組の車輪は一定の方向へ向けられた走行輪であり、前後のいずれかの組の車輪若しくは中間の組の車輪を昇降可能に設けることにより、前後いずれかの組の車輪と中間の組の車輪が接地する走行状態と、前後２組の車輪が接地する横移動可能な状態とを選択し得るように構成するという手段を講じたものである。   In order to solve the above-mentioned problems, the present invention relates to a wheelchair having a main body having wheels as moving means and a chair portion attached to the main body, and the main body has three front, middle and rear wheels. Among them, the front and rear two sets of wheels are caster wheels that can be oriented in any direction, the middle set of wheels is a traveling wheel directed in a certain direction, and either the front or rear set of wheels or the intermediate set of wheels Is provided so as to be able to move up and down, so that a traveling state in which one of the front and rear wheels and the middle wheel are grounded and a laterally movable state in which the two front and rear wheels are grounded can be selected. This is a measure taken.

本発明に係る車椅子は、横移動手段を有することを特徴とするものであるが、横移動とは、車椅子の進行方向を縦と見て横方向への移動ということである。また、車椅子の車輪による移動を意味するのみならず、車輪以外の手段による移動をも含むものである。車輪以外の手段による移動は、椅子部の、例えばガイドレールによる左右方向への移動が該当する。   The wheelchair according to the present invention is characterized by having a lateral movement means, and the lateral movement is a movement in the lateral direction when the traveling direction of the wheelchair is viewed as a vertical direction. Moreover, not only the movement by the wheel of a wheelchair is meant, but the movement by means other than a wheel is also included. The movement by means other than the wheels corresponds to the movement of the chair portion in the left-right direction by, for example, a guide rail.

本発明に係る車椅子の場合、前、中、後３組の車輪を本体に具備している。その内、前及び後の２組の車輪は、任意の方向を向き得るキャスター輪、中間の組の車輪は一定の方向へ向けられた走行輪とする。前後いずれかの組の車輪のどれか、或いは中間の組の車輪は昇降可能に設けられるものとするが、これによって前車輪と中間車輪による接地、中間車輪と後車輪による接地、若しくは前車輪と後車輪による接地が可能となる。後述する実施形態では後車輪の昇降による前車輪と中間車輪による接地、又は前車輪と後車輪による接地が可能となっており、中間車輪が接地する場合は走行状態であり、前後の車輪が接地する場合は横移動可能な状態となる。   In the case of the wheelchair according to the present invention, the front, middle and rear three sets of wheels are provided in the main body. Among them, the front and rear two sets of wheels are caster wheels that can be directed in any direction, and the middle set of wheels is a traveling wheel that is directed in a certain direction. Any one of the front and rear wheels, or the middle wheel, shall be provided so that it can be raised and lowered, so that the grounding by the front and intermediate wheels, the grounding by the intermediate and rear wheels, or the front wheels Grounding by the rear wheel becomes possible. In the embodiment described later, the grounding by the front wheel and the intermediate wheel by raising and lowering the rear wheel, or the grounding by the front wheel and the rear wheel is possible. When the intermediate wheel is grounded, it is in a running state, and the front and rear wheels are grounded. If you do, you will be able to move horizontally.

多くの場合、各組の車輪は左右２個で構成される。しかし、中央の車輪を除く、前又は後の組の車輪は２個１組でなければならないとも断言できず、用途機種によっては１個で良い可能性もある。いずれのケースにおいても、中間の走行輪が接地する場合には走行状態になり、中間の走行輪が接地せず、前後のキャスター幅だけが接地する場合には全方向へ移動できるので、横方向移動可能な状態になる。   In many cases, each set of wheels consists of two left and right wheels. However, it cannot be stated that the front or rear set of wheels other than the central wheel must be a set of two, and depending on the application model, there may be one. In either case, the vehicle is in a running state when the intermediate traveling wheel is in contact with the ground, and the intermediate traveling wheel is not in contact with the ground, and only the front and rear caster widths are in contact with each other. It becomes movable.

どの車輪を接地させるか或いは接地させないかについては、公知の任意の方法を採用することによって実施可能となるものである。例えば本体のフレームに前の組の車輪と中間の組の車輪を取り付け、後の組の車輪は、本体のフレームに後部に上げ下げ可能に設けた可動枠に取り付けることで、走行状態と横移動状態を選択し得るものとなる。   Which wheel is to be grounded or not grounded can be implemented by employing any known method. For example, the front wheel and the middle wheel are attached to the frame of the main body, and the rear wheel is attached to a movable frame that can be raised and lowered at the rear of the main body frame. Can be selected.

このような車輪の構成に対して、椅子部の方は、本体のフレームに左右方向へ移動可能に設けることができ、この椅子部の移動も横移動手段を構成する。横移動手段としては本体のフレームに左右方向へ伸びたガイドレールを設置し、このガイドレールを介して椅子部を取り付けることにより左右方向へ移動可能に設けることができる。この椅子部は本体から左又は右の側方へはみ出した位置まで移動可能であるものとするが、この椅子部の横移動を、車椅子の横移動と組み合わせることができるので、車椅子を例えばベッドに横付けして利用者を乗り移せるようになる。   In contrast to such a wheel configuration, the chair portion can be provided on the frame of the main body so as to be movable in the left-right direction, and the movement of the chair portion also constitutes a lateral movement means. As the lateral movement means, a guide rail extending in the left-right direction can be installed on the frame of the main body, and a chair portion can be attached via the guide rail so as to be movable in the left-right direction. This chair part can be moved from the main body to the left or right side position, but the lateral movement of this chair part can be combined with the lateral movement of the wheelchair. It will be possible to transfer the user sideways.

さらに椅子部は、座部と、座部後側に配置される背凭れ部、及び座部前側に配置される下肢受け部を有するものとし、背凭れ部と下肢受け部とが上下方向を向いて、全体としてクランク状に屈曲した状態から、全体が伸びて平らになった伸張状態を取り得る。いわゆるリクライニング構成である。底部と背凭れ部及び下肢受け部等はリンク機構により連結し、椅子とベッドの２形態の間の変化をワンタッチで操作し得るものとすることができ
る。 Furthermore, the chair portion has a seat portion, a backrest portion disposed on the rear side of the seat portion, and a lower limb receiving portion disposed on the front side of the seat portion, and the backrest portion and the lower limb receiving portion face in the vertical direction. Thus, it is possible to take a stretched state where the entire body is flattened from a state in which it is bent in a crank shape as a whole. This is a so-called reclining configuration. A bottom part, a backrest part, a lower limbs receiving part, etc. can be connected by a link mechanism, and a change between two forms of a chair and a bed can be operated with one touch.

本発明は上記のように構成されかつ作用するものであるから、車輪の調節による横移動、及び必要に応じて行われる椅子部による横移動によって、利用者が全く歩かずかつ自立できない状態でも、寝たままの姿勢で側方から乗り降りすることができ、利用者のみならず介護者にとっても負担の軽減となる。また、椅子部が伸張するため単に車椅子としてのみならず、ベッドないしはストレッチャーとしても使用可能であり、例えば介護タクシーへの乗り降りの用途などに好適である。   Since the present invention is configured and operates as described above, even if the user does not walk at all and cannot stand by the lateral movement by adjusting the wheel and the lateral movement by the chair portion as necessary, It is possible to get on and off from the side in a lying posture, reducing the burden not only on the user but also on the caregiver. Further, since the chair portion extends, it can be used not only as a wheelchair but also as a bed or a stretcher, and is suitable for use in getting on and off a care taxi, for example.

以下図示の実施形態を参照して、本発明をより詳細に説明する。図１において、車椅子１０は本体１１と椅子部２５とから成り、本体１１は移動手段として前、中、後３組の車輪１２、１３、１４を有しており、前、中、後の車輪１２、１３、１４はすべて左右２個１対から成る。その内、前後２組の車輪１２、１４は任意の移動方向を向き得るキャスター輪、中間の組の車輪１３は一定の方向へ向けられた走行輪であり、大径車輪から成っている。上記前の組の車輪１２と中間の組の車輪１３とは、本体１１を構成しているフレーム１５に取り付けられており、車椅子として走行させるときにはこれらの４個の車輪が使われる。これに対して後の組の車輪１３は、本体１１のフレーム後部に上げ下げ可能に設けられた、可動枠１６に取り付けられている。   Hereinafter, the present invention will be described in more detail with reference to the illustrated embodiments. In FIG. 1, the wheelchair 10 includes a main body 11 and a chair portion 25, and the main body 11 has three sets of wheels 12, 13, and 14 as moving means, and the front, middle, and rear wheels. 12, 13, and 14 are all made up of a pair of left and right. Among them, the two sets of front and rear wheels 12 and 14 are caster wheels that can face any moving direction, and the middle set of wheels 13 is a traveling wheel that is directed in a certain direction, and consists of large-diameter wheels. The wheel 12 of the previous group and the wheel 13 of the middle group are attached to a frame 15 that constitutes the main body 11, and these four wheels are used when traveling as a wheelchair. On the other hand, the rear set of wheels 13 is attached to a movable frame 16 provided at the rear of the frame of the main body 11 so as to be raised and lowered.

例示のものにおいて、可動枠１６は、本体フレーム１５の後端に枢軸１７によって回転可能に軸支され、後の組の車輪１４の取り付けアーム１８は、本体フレーム１５の前端に軸１９によって回転可能に軸支され、さらに枢軸１７から伸びる回転アーム２１と、リンクアーム２２を介して連結されている。これにより、可動枠１６の枢軸１７を中心とした回転により死点を越えて下げると後の組の車輪１４が下降して中間車輪１３の接地部よりも下方まで移動し、可動枠１６を枢軸１７を中心として死点を越えて上げると後の組の車輪１４は上昇して中間車輪１３の接地部よりも上の位置に移動するように構成されている（図４、図５参照）。図中２３はハンドルであり、可動枠１６の操作のために取り付けられている。   In the illustrated example, the movable frame 16 is rotatably supported by the pivot 17 at the rear end of the main body frame 15, and the mounting arm 18 of the rear set of wheels 14 is rotatable by the shaft 19 at the front end of the main body frame 15. Are connected to each other via a link arm 22 and a rotary arm 21 that is supported by the shaft 17 and extends from the pivot shaft 17. As a result, when the movable frame 16 is rotated about the pivot 17 and lowered beyond the dead point, the subsequent pair of wheels 14 descends and moves below the grounding portion of the intermediate wheel 13 to move the movable frame 16 to the pivot. If it raises beyond a dead center centering on 17, the wheel 14 of the latter group will raise, and it is comprised so that it may move to the position above the contact part of the intermediate | middle wheel 13 (refer FIG. 4, FIG. 5). In the figure, reference numeral 23 denotes a handle, which is attached for operating the movable frame 16.

椅子部２５は、本体１１のフレーム上に配置されるベースフレーム２６を有しており、本体フレーム１５とこのベースフレーム２６とは堅固に一体化され、ベースフレーム上に設けた左右方向への移動のためのガイドレール２７によって、左右どちらの方向へも移動可能に設けられている。車輪以外による左右方向への移動手段のために、本体１１の左右側方へはみ出した任意の位置にて移動を停止させるために、椅子部２５の側に左右方向へのラック部材２８を設けており、その凹部２８ａと噛み合う係合子２９ａを有する操作レバー２９をベースフレーム２６の側に設けている（図６、図７参照）。ガイドレール２７による左右方向への移動構成に基く横移動手段によって、図６に示したように、本発明に係る車椅子１０をベッド２０の際に押し付けることが可能となる。   The chair portion 25 has a base frame 26 disposed on the frame of the main body 11, and the main body frame 15 and the base frame 26 are firmly integrated and moved in the left-right direction provided on the base frame. Is provided so as to be movable in either the left or right direction. A rack member 28 in the left-right direction is provided on the side of the chair portion 25 in order to stop the movement at an arbitrary position protruding to the left and right sides of the main body 11 for the means for moving in the left-right direction by means other than wheels. An operating lever 29 having an engaging member 29a that meshes with the recess 28a is provided on the base frame 26 side (see FIGS. 6 and 7). As shown in FIG. 6, the wheelchair 10 according to the present invention can be pressed against the bed 20 by the lateral movement means based on the horizontal movement structure by the guide rail 27.

例示されている椅子部２５は、座部３１と、その後側に位置する背凭れ部３２、座部３１の前側に位置する下肢受け部３３及びその先端の足乗せ部３４とを有しており、各部は折り曲げ可能にヒンジ結合されている。また背凭れ部上にはヘッドレスト３５を有する。さらに各部３１、３２、３３、３４は屈伸可能なようにリンク機構によって連結されており、例示のリンク機構は、背凭れ部３２の後方下部から下方へ突出させたアーム３６と、下肢受け部３３から斜め下方へ突出させた傾斜アーム３７と、それら両アーム３６、３７を連結した連結ロッド３８と、アーム３６と連結ロッド３８の結合点にピストン３９の先端を軸支し、シリンダー４１の他端を背凭れ部３２の上部に軸支した伸縮装置４０と、を有している。さらに、足乗せ部３４とベースフレーム２６には夫々のアーム４２、４３を連絡するロッド４４を設けているので、足乗せ部３４も連動して後述のように姿勢を変化させることが可能な構成を有している。   The illustrated chair portion 25 includes a seat portion 31, a backrest portion 32 located on the rear side, a lower limb receiving portion 33 located on the front side of the seat portion 31, and a footrest portion 34 at the tip thereof. Each part is hinged so that it can be bent. A headrest 35 is provided on the backrest. Furthermore, each part 31, 32, 33, 34 is connected by a link mechanism so as to be able to bend and stretch. The illustrated link mechanism includes an arm 36 that protrudes downward from the lower rear part of the backrest part 32, and a lower limb receiving part 33. An inclined arm 37 projecting obliquely downward from the arm 36, a connecting rod 38 connecting the arms 36 and 37, a tip of the piston 39 pivotally supported at the connecting point of the arm 36 and the connecting rod 38, and the other end of the cylinder 41 And a telescopic device 40 pivotally supported on the upper portion of the backrest portion 32. Furthermore, since the footrest 34 and the base frame 26 are provided with rods 44 for connecting the respective arms 42 and 43, the footrest 34 can be linked to change the posture as described later. have.

４５は上記伸縮装置の操作レバーであり、いわゆるリクライニング姿勢を制御する。４６はハンドルであり、背凭れ部３２の後部に取り付けられ、上記レバー４５及びブレーキレバー４７をハンドル枠部に有している。また本発明に係る車椅子１０は、肘当て４８、４８を有する。側面からの乗り降りという性質上、肘当て４８、４８は邪魔であるが、車椅子１０としての使用上は必要性が高いので、ベースフレーム２６の前方から抜き差し式に着脱できるように設けている。４９は差し込み部、５１はその受け入れのための嵌合部を示す。   Reference numeral 45 denotes an operation lever of the telescopic device, which controls a so-called reclining posture. A handle 46 is attached to the rear portion of the backrest portion 32 and has the lever 45 and the brake lever 47 in the handle frame portion. The wheelchair 10 according to the present invention has elbow pads 48 and 48. Although the elbow pads 48 and 48 are obstructive due to the nature of getting on and off from the side, they are highly necessary for use as the wheelchair 10, and are provided so as to be detachable from the front of the base frame 26. Reference numeral 49 denotes an insertion portion, and 51 denotes a fitting portion for receiving the insertion portion.

このように構成された本発明に係る車椅子１０は、車椅子１０として使用するときには、椅子部２５がクランク状に屈曲した図１の状態を取り、かつ肘当ても使用することができる。この場合、利用者は正面から乗り降りすることになる。また走行輪である中間の車輪１３と前車輪１２のキャスター輪が接地し、後の組の車輪１４は接地しないので、介護者が押して移動させる走行状態として使用するのに適している。可動枠操作ハンドル２３を押して後の組の車輪１４を接地させることにより、それまで浮いていた後車輪１４が中間の組の車輪１３に代わって接地するようになり、全てキャスター輪による接地となる（図５）。この前後２組共キャスター輪による接地では横移動が自由であり、図６に示すように例えばベッド２０に横から接近させることができる。さらに、椅子部２５から肘当て４８を取り外しておき、操作レバー２９を操作してベースフレーム２６への固定を解除すると、椅子部２５を左右方向へ移動させることができるので、車椅子１０とベッド２０との間に空間５０がある場合でも、椅子部２５の横移動によりベッド２０に接触する程度まで近付けられることになる。その椅子部２５は、伸縮操作レバー４５の操作により図８に示したようにほぼ水平の状態に姿勢を変化させることができるので、ベッド上に寝ている利用者を、単に横にずらせるだけで、本発明に係る車椅子上に移乗させることが可能である。なお、車椅子１０への利用者の乗り移り、或いは車椅子１０からの利用者の離脱などの際にはブレーキレバー４７を操作して主車輪である中間の組の車輪１３を制動状態におく。   When the wheelchair 10 according to the present invention configured as described above is used as the wheelchair 10, the chair portion 25 is bent in a crank shape as shown in FIG. 1 and an armrest can also be used. In this case, the user gets on and off from the front. In addition, since the intermediate wheels 13 and the caster wheels of the front wheels 12 are grounded and the rear wheels 14 are not grounded, it is suitable for use as a traveling state in which the caregiver pushes and moves. By pushing the movable frame operation handle 23 and grounding the subsequent set of wheels 14, the wheels 14 are grounded instead of the intermediate set of wheels 13 after floating up to that point, and all are grounded by caster wheels. (FIG. 5). In the ground contact by the two sets of front and rear caster wheels, the lateral movement is free, and for example, the bed 20 can be approached from the side as shown in FIG. Furthermore, if the elbow rest 48 is removed from the chair portion 25 and the operation lever 29 is operated to release the fixation to the base frame 26, the chair portion 25 can be moved in the left-right direction. Even if there is a space 50 between the two, the chair portion 25 is moved close to the bed 20 by the lateral movement. Since the chair portion 25 can change its posture to a substantially horizontal state as shown in FIG. 8 by operating the telescopic operation lever 45, the user who is sleeping on the bed is simply shifted sideways. Therefore, it is possible to transfer onto the wheelchair according to the present invention. In addition, when the user is transferred to the wheelchair 10 or the user is detached from the wheelchair 10, the brake lever 47 is operated to put the middle pair of wheels 13 as the main wheels into a braking state.
