Description

Mobile car

本發明是關於即使是以健康人為首，以及如腿和腰衰弱的老人或肢體行動不便者等需要介護的被介護者也能容易地使用並移動，即使長時間使用也不會給予背或腰等負荷，特別是即使是使用者的脊椎等有損傷的情形也能不勉強而使用，與床、馬桶座、輪椅等的移乘也容易且通用性佳的移動車。
The present invention relates to an care recipient who is in need of care, such as a healthy person, and an elderly person who is weak in the legs and waist, or a person with reduced mobility, can easily use and move, and will not give back or waist even if used for a long time. In other cases, even when the user's spine or the like is damaged, it can be used without difficulty, and it is easy to move with a bed, a toilet seat, a wheelchair, etc., and the versatility of the mobile vehicle.

    以往，一般由於下肢的麻痺等即使使用拐杖等步行也困難的人可自己一邊操作一邊移動以當作自己的代步的輪椅被廣泛使用。作為輪椅的標準型最普及的類型是由安裝於椅子的前方的小車輪與後方的大車輪構成，小車輪被稱為腳輪(caster)，為自由旋轉的自在輪(caster)。大車輪為驅動輪，裝有行走用環圈(手推圈(hand rim))，成為靠自己轉動手推圈而駕駛的結構。為了隨心所欲地操作該輪椅，除了上下輪椅訓練或行走訓練外，平衡良好地乘坐的訓練也很重要。在標準型的情形下若上肢的肌肉力量不強，則操作很難進步。其他的輪椅也有以操作更簡單且適合高齡者的前方大車輪型、兩手無法使用者用的單手驅動型、戶外行走用的手動鏈條型等為首，以及手推型、俯臥姿勢行走型等的特殊型。而且，也有輕便且容易折疊的攜帶用且容易被放置於汽車上的輪椅，或為了無法以手操作的人，僅藉由按壓開關就能操作的電動式輪椅等。
    但是，因通常的輪椅在就座部的後方有靠背，必須由前方上下，故需要一時站起來改變身體的方向並坐下此一動作，當由床或廁所的馬桶座等換乘時，往往必須借助介護者。
    特別是在床與輪椅等之間使像久病的人或腿和腰衰弱的老人等身體行動不便且需要介護的被介護者移乘時，雖然介護者摟抱被介護者，或者使用被稱為升降機(lifter)的移乘機器等，但當介護者摟抱被介護且支撐體重時，給予介護者的負擔大，會成為腰痛等的原因。而且，在上下輪椅時有時也會失去平衡等而發生跌倒事故，故缺乏使用性。
    而且，在通常的輪椅中由於靠背使得背部也受到壓迫，特別是脊椎損傷患者的情形若因脊髓損傷而失去感覺，則無法感覺肉體的苦痛，有時也會產生血流受阻礙(impeded blood flow)等。而且，脊椎損傷患者的輪椅座位姿勢呈脊柱後彎大大地使骨盤後傾的姿勢，與健康人比較因具有壓力容易集中於狹窄範圍的傾向，故需特別注意座位姿勢。
    另一方面，當使用升降機時，為了懸吊被介護者的準備很費事，不僅介護者的負擔增加，也需要用以設置、收納機械的大的空間。特別是在懸吊被介護者的臀部的構造中，有給予被介護者恐怖感或不快感的問題點，在支撐被介護者的腋下的構造中，必須以兩側支撐被介護者的體重，有給予被介護者疼痛或不快感的問題點。
    而且，持續久病的生活的被介護者其肌肉減弱，往往住院也會長期化。為了防止該等問題點，需透過看護(caregiving)或復健(rehabilitation)等定期地活動身體或頻繁地更換姿勢，對介護者也成為大的負擔。
    雖然可減輕介護者或被介護者的負擔，對復健也有效果的助行器(walker)也被使用，但未配設就座部，在疲勞時需準備別的椅子，而且，有輪式助行器因無停機裝置(shut-down device)，故缺乏站住時的穩定感，尤其不適合在戶外或斜面的使用，用途或使用場所被限定，缺乏通用性。
    為了解決該等問題點，例如在(專利文獻1)揭示有[具備在使被介護者坐在座部的狀態下運送的台車部之附有移乘功能的介護椅子]。
    而且，在(專利文獻2)揭示有[由在具有腳輪的台座立設主柱，在嵌合於該主柱的中空軸配設台桌(table)與椅子，並且沿著主柱使台桌與椅子升降的升降裝置構成的介護用人體移動裝置]。在(專利文獻3)揭示有[由安裝於椅子的前方的小車輪與後方的大車輪構成，在成為驅動輪的大車輪裝有行走用環圈(手推圈)，靠自己轉動手推圈而駕駛的輪椅]。

    [專利文獻2]日本國特開2000-225155號公報
    [專利文獻3]日本國特開2011-147767號公報In the past, wheelchairs that are difficult to walk, such as paralysis of the lower limbs, can be widely used because they can move while operating as a driver. The most popular type of standard type of wheelchair is composed of a small wheel attached to the front of the chair and a large wheel at the rear. The small wheel is called a caster and is a freely rotatable caster. The large wheel is a driving wheel, and is equipped with a walking ring (hand rim), which becomes a structure for driving by turning the hand to push the ring. In order to operate the wheelchair as desired, in addition to the up and down wheelchair training or walking training, it is also important to have a well-balanced training. In the case of a standard type, if the muscle strength of the upper limb is not strong, the operation is difficult to progress. Other wheelchairs include the one-hand drive type that is simpler to operate and suitable for the elderly, the one-hand drive type that can not be used by both hands, the manual chain type for outdoor walking, and the push type and the prone position. Special type. Further, there is also a wheelchair that is light and easy to fold and that can be easily placed on a car, or an electric wheelchair that can be operated only by pressing a switch for a person who cannot operate by hand.
However, since a normal wheelchair has a backrest at the rear of the seating portion, it must be moved up and down from the front, so it is necessary to stand up and change the direction of the body and sit down this movement. When the toilet seat of the bed or toilet is transferred, often Must rely on the caregiver.
In particular, when a careless person who is inconvenient and in need of care is transferred between a bed, a wheelchair, etc., such as a person with a long illness or an elderly person with a weak leg and a weak waist, the caregiver cuddles the care recipient, or the use is called A lifter or the like of a lifter, but when the caregiver is shackled and supports the weight, the burden on the caregiver is large, which may cause back pain or the like. Further, in the case of getting on and off a wheelchair, there is a case where a balance or the like is lost and a fall accident occurs, so that the usability is lacking.
Moreover, in a normal wheelchair, the back is also pressed by the backrest, and in particular, if the patient with a spinal injury loses the feeling due to the spinal cord injury, the pain of the body cannot be felt, and sometimes the blood flow is impeded (impeded blood flow). )Wait. Further, in the wheelchair seat posture of the spine-injured patient, the posture in which the spine is bent backwards greatly tilts the pelvis, and it tends to concentrate on the narrow range as compared with the healthy person, so it is necessary to pay special attention to the seat posture.
On the other hand, when the elevator is used, it is very troublesome to suspend the preparation of the caregiver, and not only the burden on the caregiver is increased, but also a large space for installing and accommodating the machine is required. In particular, in the structure of the buttocks of the anchored caregiver, there is a problem of giving a feeling of horror or discomfort to the care recipient, and in the structure supporting the underarm of the care recipient, the weight of the care recipient must be supported on both sides. There is a problem of giving pain or discomfort to the care recipient.
Moreover, the care recipients who have sustained a long-term illness have weakened muscles, and often the hospitalization is prolonged. In order to prevent such problems, it is necessary to periodically move the body or frequently change the posture through caregiving or rehabilitation, which is also a great burden on the caregiver.
Although it is possible to reduce the burden on the caregiver or the caregiver, a walker that is effective for rehabilitation is also used, but the seat is not provided, and other chairs are required for fatigue, and there are wheels. Since the walker has no shutdown device, it lacks a sense of stability when standing, and is particularly unsuitable for use outdoors or on a slope, where the use or place of use is limited, and lacks versatility.
In order to solve such a problem, for example, (Patent Document 1) discloses [a protective chair having a transfer function in a bogie portion that is transported in a state where the caretaker is seated in the seat portion].
Further, (Patent Document 2) discloses that [the main column is erected on the pedestal having the casters, the table and the table are arranged on the hollow shaft fitted to the main column, and the table is placed along the main column. A human body moving device for preventing care by a lifting device for lifting and lowering a chair]. (Patent Document 3) discloses that [the small wheel attached to the front of the chair and the large wheel at the rear, and the large wheel that is the driving wheel is provided with a running ring (hand push ring), and the hand is turned by the hand. And driving a wheelchair].

    但是，上述習知的技術有如下的課題。
    (1)、(專利文獻1)之附有移乘功能的介護椅子因與一般的椅子一樣在座部的背後具有靠背，故在使用前將靠背放倒直到座部與靠背成平行為止，或者一時將靠背卸下後，必須使座部移動到床上，將座部的高度調整到床的高度，將被介護者放置於座部之上後，使座部上升，由床拉出附有移乘功能的介護椅子全體，有程序繁雜且缺乏使用性之課題。
    而且，有如下的課題:有在使用狀態下靠背造成的給予背部的壓迫，尤其不適合脊髓損傷者的使用。
    (2)、(專利文獻2)之介護用人體移動裝置其椅子藉由配設於後部中央的軸而可雙開地形成，由被移乘者的腰的後方使其接觸敞開的椅子，介護者必須一邊交互將被移乘者的左右的大腿部抬起，一邊將座位插入臀部，有介護者費事，缺乏使用性，並且椅子的構造複雜且缺乏量產性之課題。
    而且，因座位被左右分割，故有強度容易不足，確實地支撐介護者的體重很困難，且缺乏耐久性、體重支撐的穩定性之課題。
    (3)、以(專利文獻3)為首的該等習知的輪椅都在就座部的後方有靠背，必須由前方上下，故需要一時站起來改變身體的方向並坐下此一動作，當由床或廁所的馬桶座等換乘時，往往必須借助介護者。
    特別是在床與輪椅等之間使像久病的人或腿和腰衰弱的老人等身體行動不便且需要介護的被介護者移乘時，雖然介護者摟抱被介護者，或者使用被稱為升降機的移乘機器等，但當介護者摟抱被介護者且支撐體重時，給予介護者的負擔大，會成為腰痛等的原因。而且，在上下輪椅時有時也會失去平衡等而發生跌倒事故，故缺乏使用性。
    (4)、再者，在(專利文獻1)至(專利文獻3)中由於靠背使得背部也受到壓迫，特別是脊椎損傷患者的情形若因脊髓損傷而失去感覺，則無法感覺肉體的苦痛，有時也會產生血流受阻礙等。而且，脊椎損傷患者的輪椅座位姿勢呈脊柱後彎大大地使骨盤後傾的姿勢，與健康人比較因具有壓力容易集中於狹窄範圍的傾向，故需特別注意座位姿勢。
    而且，有在使用狀態下因靠背造成的給予背部的壓迫，特別是有不適合脊椎損傷患者使用的課題。
    本發明是為了解決上述課題，其目的為提供一種可不改變身體的方向而在與床、馬桶座、輪椅等之間簡單地移乘，構造簡單且即使是一個人也能使用，並且不會給予使用者的背或腰等負荷，可長時間使用，特別是即使是脊椎等有損傷的情形也能不勉強而使用，不僅可大幅減輕介護者及被介護者(使用者)的負擔，同時不限於老人或肢體行動不便者等，健康的小孩到大人都能簡單地使用以取代腳踏車、機車、輪椅等而進行長距離的移動之功能性、穩定性、通用性、操作性佳的移動車。
    為了解決上述習知的課題，本發明的移動車具有以下的構成。
    本發明的申請專利範圍第1項記載的移動車具有如下的構成:使用者一個人移乘，使用以取代腳踏車、機車、輪椅而用以進行在戶內、戶外的移動，

    藉由該構成，可得到如下的作用:
    (1)、就座部無靠背，可由台部的後方或側方上下，在移乘時無須分解就座部或使就座部變形，特別是使用者為腿和腰等衰弱的被介護者的情形，可由就座於床或馬桶座等的狀態不改變身體的方向下容易由台部後方跨過就座部而就座，無須藉助介護者的手就能一個人進行移乘，可藉由台部支撐被介護者(使用者)的體重，跌倒等很難發生，可大幅減輕介護者及被介護者(使用者)的負擔，故省力性(labor-saving ability)、使用性佳。
    (2)、因具有立設於就座部的前端側，抵接使用者的胸部之護胸墊部，故可藉由以前傾姿勢抱住護胸墊部而將體重落於護胸墊部，可藉由就座部及護胸墊部分散體重而確實地支撐使用者的身體，即使無靠背也能以穩定的姿勢維持長時間的座位姿勢或立位姿勢或者進行移動，可減輕給予使用者的背部或腰等的負擔，故安全性、使用性佳。
    (3)、藉由使護胸墊部抵接使用者的胸部，可描繪脊椎透過頸椎而前彎、透過胸椎而後彎、透過腰椎而前彎的S字形的曲線(curve)，且可採取接近骨盤稍微前傾的正常的立位姿勢的姿勢，可保持體重均勻地分散於坐骨結節(ischial tuberosity)的理想的座位姿勢，可減輕使用者的負擔，故長時間的連續使用性佳。
    (4)、因就座部及護胸墊部對台部被移動自如地保持於前後方向及上下方向，故可依照床或馬桶座等的移乘對象物的高度及/或使用者的體格、姿勢等自在地調整就座部或護胸墊部的位置，因可使移乘對象物與就座部接近，故可一個人簡便地進行移乘動作，即使是在移乘對象物的下部無台部的插入空間的情形也能使用，故通用性佳。
    (5)、因可使就座部或護胸墊部前後移動或上下移動，故可使就座部或護胸墊部移動到台部的後方或下方且使用者可安全且簡便地上下，並且在就座後可藉由使就座部或護胸墊部移動到前方或上方而將使用者保持於所需的姿勢(角度)，或抬起到所需的高度，能以使用者的輕鬆的姿勢進行移動，故使用性佳。
    (6)、由於是無靠背，使用者的背面(就座部的後方)被敞開的背面敞開型，故當使用者為脊椎或腰椎等背部或腰有損傷的患者時，仍舊可容易由背面(背部)進行診察，無須朝床等移動，可減輕使用者的負擔，並且可縮短診察所需的時間，故診察性佳。
    (7)、因台部具有行走部，故不限於老人或肢體行動不便者等，健康的小孩到大人廣泛的使用者可簡單地使用以取代腳踏車、機車、輪椅等而進行在戶內、戶外的移動。
    (8)、因當使就座部移動到上方時，能以接近立位的姿勢移動(行走)，故與習知的輪椅比較，使用者可確保寬廣的視野，來自他人的能見度(visibility)也高，可避免碰撞等的事故，安全性佳並且可防止血流的惡化，可使用以取代輪椅而進行長距離的移動，故使用性佳。
    (9)、因可使就座部或護胸墊部移動到上方，或使護胸墊部移動到前方，故手也搆得到在習知的輪椅所不及的地方，也能進行將東西取出和放入到高處或門的開關、洗臉或烹調等，可擴大作業範圍，故功能性佳。
    (10)、當使用電動的驅動手段等使其前後移動或上下移動到就座部時，可使使用者的髖關節(hip joint)、膝關節(knee joint)、踝關節(ankle joint)等運動，即使是一個人也能進行利用屈伸運動等的下半身的關節可動域(range of motion)的擴大或肌肉力量增強、血流的改善等的復健，可防止下半身的運動功能的降低或水腫(edema)等，故功能性、省力性佳。
    (11)、由於具有在台部的後方低位置與台部的前方高位置之間使就座部移動並進行就座部的前後移動及上下移動之驅動機構部，可藉由一次的動作迅速地使就座部移動至最適於移乘或上下、移動(行走)的位置，故省力性、使用性佳。
    (12)、因在台部的後方低位置與前方高位置之間使就座部移動時，可藉由將使用者的體重落於前方的護胸墊部而支撐，故不會失去平衡而能安全地進行前後移動及上下移動，無落下或跌倒之虞，任何人都能放心簡單地使用，故動作的穩定性、可靠度(reliability)佳。
    (13)、藉由透過驅動機構部使就座部移動，依照移動(行走)速度或使用者的體格等簡便地調整重心高度(位置)，可維持穩定的姿勢，故行走時的安全性、姿勢的穩定性佳。
    (14)、藉由透過驅動機構部使就座部及護胸墊部上下移動時的就座部及護胸墊部的移動方向由台部的後方低位置朝前方高位置動作，可迅速地使就座部及護胸墊部移動至最適於移乘或上下、移動(行走)的位置，故省力性、使用性佳。
    (15)、藉由使護胸墊部由台部的後方低位置移動到前方高位置，使用者不會失去平衡，可安全地進行平順的體重移動，無落下或跌倒之虞，任何人都能放心簡單地使用，故動作的穩定性、可靠度佳。
    此處，雖然台部可選擇任意的形態，但台部的前後左右的尺寸為在使用者搭乘且使就座部或護胸墊部前後移動或上下移動時不會失去平衡且不會跌倒而形成較佳。此外，藉由將使用者承載腳的台部頂面作成無凹凸的平面，在移乘時不會妨礙腳的移動，故使用性佳。
    若行走部能使台部移動(行走)的話即可，電動或手動都可以。不限於車輪，也可以為具備履帶(crawler)或多足步行(multi-legged walking)的腳部等。具備車輪當作行走部的情形的數目或配置可適宜選擇。當各配設兩個前輪、後輪時，可確實支撐使用者的體重且可在戶內或戶外自在地使移動車移動，故體重支撐及移動的穩定性佳。也可在台部具有動力部，可正反旋轉的馬達適合被使用。若以前輪與後輪的至少任一方當作驅動輪也可以，惟以全輪驅動(all-wheel drive)也可以。驅動輪若為可操作配設於移動車的任意的位置的加速器(accelerator)等而移動移動車本體者即可。特別是當可全方向移動台部時，具有小的轉彎半徑，故機動性佳。
    此外，當令行走部為電動時，動力源可將電池安裝於台部。當電池的容量不足無法行走時，透過離合器(clutch)操作，藉由介護者等進行的手推的移動為可能而構成較佳。當與動力部或動力源一起將驅動輪配設於台部的前方時，於在使用者就座的狀態下就座部移動於台部的後方或下方，重心朝台部的後方側移動時，該等構件可當作重錘(weight)發揮使台部水平地穩定的作用。而且，將前輪與後輪形成同程度的大小，配設與車子或機車一樣的操舵機構也可以。乃因特別是在戶外等的行走性、操作性佳。
    電池以可充電的二次電池(secondary battery)較佳，可使用鎳鎘電池(Nickel-Cadmium battery)、鎳氫電池(Nickel-Metal Hydride battery)、鋰離子二次電池(Lithium-ion rechargeable battery)、鉛電池(lead battery)等。而且，當電池為裝卸自如時，即使是由移動車卸下用完的電池進行充電的時候，也能搭載其他充電完了的電池而驅動，故使用性佳。移動車也能在台部裝設備用的電池，可藉由裝設備用電池而拉長行走距離。此外，用以驅動驅動機構部的操作部可適宜配置於護胸墊部等的所需的位置。
    行走部的車輪可選定任意的形態的車輪，惟當使用包含胺甲酸乙酯泡沫(urethane foam)的防爆輪胎時，無須擔心爆胎或無須進行氣壓的調整，故使用性佳。而且，若在各個車輪配設懸吊系統(suspension)的話，則可使乘坐時的感覺舒適。此外，在移動車配設煞車(brake)較佳。乃因可在移乘時確實地固定移動車，可安全地進行移乘動作。
    煞車可使用將金屬線(wire)連結於煞車桿(brake bar)，拉該金屬線並將煞車緩衝墊(brake pad)緊壓於驅動輪的輪緣(rim)等的構造者或電磁煞車(electromagnetic brake)等。煞車桿可配設於使用者容易操作的任意的位置，惟藉由配設於護胸墊部的左右的任一個附近而在移乘時也能踩煞車並使台部固定，故安全性佳。
    此外，藉由在台部的前方或側方配設以金屬製的管子等形成格子狀的護腳(foot guard)，也能以立位姿勢參加足球等的比賽。
    就座部是支撐使用者的臀部，可選擇任意的形狀，而當形成寬度由頂端緩緩地擴大到中央附近，隨著由中央附近進行到後方而以更大的比例擴大寬度的尖頭型時，在移乘時不會造成妨礙，且在使就座部上升並採取立位姿勢時不會妨礙大腿部的操作，故使用性佳。
    在移乘時為了容易在就座部的表面滑動臀部且使移動容易，以摩擦係數低的皮革或聚胺甲酸酯纖維(polyurethane fiber)、醯胺纖維(aramid fiber)等的材質包覆就座部的表面，或在表面配設多數個滾輪(roller)也可以。此外，當在就座部的金屬製或合成樹脂製的基部(base)與表皮之間放入以胺甲酸乙酯(urethane)等的高分子化學物質製作的發泡材時，除了振動及碰撞的吸收外，也可使坐骨下等的高壓點的壓力分散，可改善神經的壓迫或血液循環等，減輕臀部的疼痛。而且，也能以防止臀部的悶熱的目的在就座部設有通氣孔或以網目構造(mesh structure)的質料形成表皮。
    護胸墊部可選擇任意的形狀，惟選擇不給予使用者的胸部一部分的壓迫或難受的感覺的面積、形狀、硬度較佳。在金屬製或合成樹脂製的基部與表皮之間放入以胺甲酸乙酯等的高分子化學物質製作的發泡材(襯墊(cushion))者較佳。而且，以防止胸部的悶熱的目的，與就座部一樣在護胸墊部設置通氣孔或以網目構造的質料形成表皮也可以。
    此外，於使用者在搭乘移動車時可直視的護胸墊部的頂面等配設顯示電池的殘餘容量的顯示部也可以。可使燈的顏色或點亮狀態等變化，顯示電池的殘餘容量，使用者可放心出門。
    當在護胸墊部的兩側部配設握持部時，可在移動時抓住握持部並保持身體，故姿勢的穩定性、安全性佳。而且，當在台部的兩側部配設框架部時，在就座部的升降時可支撐使用者的兩側，或者使用者可搭放胳臂而休息等，故使用性佳。
    就座部或護胸墊部的移動為電動或手動都可以。當具備電動的驅動機構部時，能以簡便的操作使就座部或護胸墊部移動到所需的位置，故操作性、省力性佳。此外，就座部與護胸墊部為一體使其前後移動或上下移動也可以，且各自獨立使其前後移動或上下移動也可以。例如可使用:使用四連桿組(four-bar linkage)等透過轉動使其前後移動及上下移動者，或藉由齒條(rack)與小齒輪(pinion)的組合、伸縮鐵(lazy tongs)等的連桿組(linkage)、油壓或氣壓氣缸(cylinder)、滾珠螺桿(ball screw)等的升降手段使其上下移動者等。而且，也能由台部的後方低位置到前方高位置斜斜地配置升降手段且同時使就座部的前後移動與上下移動進行。
    此外，藉由在使就座部移動到與移乘對象相同高度時，就座部的後端為與台部的後端部約略相同的位置或比台部的後端部還突出於後方而配置，可使就座部與馬桶座等的移乘對象接近，使得在移乘對象與就座部之間很難產生間隙，可容易進行移乘作業。
    此外，移動車也可藉由使用可攜式電話(portable telephone)等的移動通訊裝置(mobile communication equipment)或無線LAN(wireless Local Area Network:無線區域網路)等的遠程操作(remote operation)進行驅動。此情形，可藉由在使用者就座於床等的狀態下遙控操作操縱桿(joystick)等，使位於遠距離的(手搆不到的)位置的移動車移動，可進行定位於最佳的移乘位置，可在無介護者的輔助下由床等移乘到移動車，可減輕介護者的負擔。
    申請專利範圍第2項記載的發明是申請專利範圍第1項記載的移動車，具有如下的構成:前述驅動機構部使用活塞氣缸(piston cylinder)或滾珠螺桿進行前述就座部及前述護胸墊部的前後移動及上下移動。
    藉由該構成，除了申請專利範圍第1項的作用外還可得到如下的作用:
    (1)、能以一次的動作迅速地使就座部移動至最適於移乘或上下、移動(行走)的位置，故省力性、使用性佳。而且，因在台部的後方低位置與前方高位置之間使就座部移動時，可藉由將使用者的體重落於前方的護胸墊部而支撐，故不會失去平衡而能安全地進行前後移動及上下移動，無落下或跌倒之虞，任何人都能放心簡單地使用，動作的穩定性、可靠度佳。
    (2)、斜斜地配置油壓或氣壓氣缸、滾珠螺桿等的升降手段且可同時使前後移動與上下移動進行。
    (3)、可藉由使用活塞氣缸，降低零件數量，簡化驅動機構部的構成，謀求小型化、輕量化，故量產性、維修保養性佳。
    此處，透過驅動機構部使護胸墊部移動時的軌跡為直線狀或圓弧狀均可。可藉由自台部的後方低位置到前方高位置斜斜地配置驅動機構部，由台部的後方低位置朝前方高位置以直線狀的軌跡使就座部移動。
    申請專利範圍第3項記載的發明是申請專利範圍第1項記載的移動車，具有如下的構成:前述驅動機構部使前述就座部及前述護胸墊部繞與前述台部的前後方向正交的水平軸轉動並進行前述就座部及前述護胸墊部的前後移動及上下移動。
    藉由該構成，除了申請專利範圍第1項的作用外還可得到如下的作用:
    (1)、藉由具有使就座部及護胸墊部繞與台部的前後方向正交的水平軸轉動並進行就座部及護胸墊部的前後移動及上下移動之驅動機構部，能以小的力量抬起使用者並使其移動，故緊密性(compactness)、省力性佳。
    (2)、因藉由以驅動機構部使就座部或護胸墊部轉動，一邊使就座部或護胸墊部後傾，一邊使其下降並使使用者移乘，或一邊使就座部或護胸墊部前傾，一邊使其上升，故能以平順的動作將使用者保持於所需的姿勢(角度)，或抬起到所需的高度，故動作穩定性佳。
    此處，驅動機構部若為藉由轉動使就座部或護胸墊部前後移動及上下移動者即可，而四連桿組等適合被使用。乃因可使機構緊密化(compacting)，故省力性佳。
    申請專利範圍第4項記載的發明是申請專利範圍第3項記載的移動車，具有如下的構成:使用透過轉動使前述就座部及前述護胸墊部前後移動及上下移動的四連桿組，當作前述驅動機構部。
    藉由該構成，除了申請專利範圍第3項的作用外還可得到如下的作用:
    (1)、可藉由具備四連桿組當作驅動機構部的機構，使驅動機構部緊密化，故省空間性佳。
    (2)、可藉由具備四連桿組當作驅動機構部的機構，由台部的後方低位置朝前方高位置沿著圓弧狀的軌跡使就座部及護胸墊部移動，故省力性佳。
    申請專利範圍第5項記載的發明是申請專利範圍第4項記載的移動車，具有如下的構成:前述驅動機構部的前述四連桿組包含:配設於前述台部之前後兩處的第一、第二連結轉動軸；配設於前述就座部的下部之前後兩處的第三、第四連結轉動軸；具有連結前述第一連結轉動軸與前述第三連結轉動軸的一個以上的連桿軸(link shaft)之前方連桿部；具有連結前述第二連結轉動軸與前述第四連結轉動軸的一個以上的連桿軸之後方連桿部；兩端部各自被轉動自如地連結並伸縮於前述前方連桿部及前述後方連桿部之連桿驅動部，前述就座部或前述護胸墊部的至少任一方被滑動自如地配設於立設於前述第三連結轉動軸或轉動自如地保持前述第三連結轉動軸與前述第四連結轉動軸的轉動軸保持部的任一個的支柱。
    藉由該構成，除了申請專利範圍第4項的作用外還可得到如下的作用:
    (1)、因驅動機構部的四連桿組具有配設於台部之前後兩處的第一、第二連結轉動軸，與配設於就座部的下部之前後兩處的第三、第四連結轉動軸，第一連結轉動軸與第三連結轉動軸及第二連結轉動軸與第四連結轉動軸各自藉由具有一個以上的連桿軸的前方連桿部及後方連桿部連結，故可藉由使兩端部被轉動自如地連結於前方連桿部及後方連桿部的連桿驅動部伸縮，在保持一定的第一、第二連結轉動軸間及第三、第四連結轉動軸間的距離下，前方連桿部及後方連桿部與台部頂面所成的角度變化，一邊使配置於第三、第四連結轉動軸的上方的就座部朝前後方向轉動，一邊使其上下移動，能以比藉由直動式的油壓或氣壓氣缸等直接使就座部上下移動還小的衝程(stroke)進行廣泛的高度調整，可謀求驅動機構部的小型化、輕量化。
    (2)、因就座部藉由前方連桿部及後方連桿部在前後兩處被支撐，故可確實地支撐使用者的體重，降低移動時的振動的產生，故姿勢的穩定化佳。
    (3)、因就座部或護胸墊部的至少任一方被滑動自如地配設於立設於第三連結轉動軸或轉動自如地保持第三連結轉動軸與第四連結轉動軸的轉動軸保持部的任一個的支柱，故可依照使用者的體格等使就座部或護胸墊部的位置上下移動，可擴大就座部或護胸墊部的可動範圍，故通用性佳。
    此處，雖然就座部配設於驅動機構部的第三、第四連結轉動軸的上方(可動部的上端側)，但第三、第四連結轉動軸被轉動自如地保持的轉動軸保持部一體形成於就座部的下部也可以，且對轉動軸保持部裝卸自如地固定就座部也可以。
    而且，護胸墊部與就座部一體化，同時進行轉動及上下移動也可以，且也能與就座部獨立而進行轉動或上下移動。
    前方連桿部及後方連桿部各自至少以一根連桿軸連結第一連結轉動軸與第三連結轉動軸及第二連結轉動軸與第四連結轉動軸，惟當以兩根連桿軸連結各個連結轉動軸的左右兩處時，能以4根連桿軸支撐使用者的體重，支撐的穩定性、耐久性、安全性佳，故較適合。
    此外，連桿驅動部為油壓或氣壓氣缸等的伸縮手段適合被使用。乃因緊密且能移動重的物品，控制容易且無噪音可平順地進行動作。
    可藉由配設用以將支柱插通於就座部或護胸墊部的插通部，進行與插通的支柱螺絲固定或銷嵌合等而固定於所需的位置。

    此外，也可以配設如下的構件:檢測就座於就座部的壓敏感測器(pressure-sensitive sensor)等的就座檢測部；在就座檢測部檢測出就座於就座部持續規定時間以上時，以聲音或光等發出警告之通報手段(notification means)。在由通報手段發出警告時，可藉由使就座部及護胸墊部前傾，將使用者的上半身落於護胸墊部，使支撐使用者的臀部的就座部後傾並由臀部敞開，防止臀部的血流受阻礙。而且，在配設檢測就座部的高度方向位置的位置感測器(position sensor)，檢測出長時間持續就座姿勢時，藉由使就座部上升並採取接近立位的姿勢，也能防止血流受阻礙。
    支柱因在前傾時成為放置使用者的體重的支撐，故立設於就座部的前端側且就座部的寬度方向中央部較佳。當支柱在台部的前後方向轉動自如且與驅動機構的連結軸同軸配設時，可簡化構造。
    此外，當在護胸墊部的前面(台部的前方側)配設進行動力部的ON/OFF或就座部的上下移動的切換的開關時，可防止在移乘時突然移動，故安全性佳。
    當在護胸墊部的至少一側部或前部具備在水平面內被轉動自如地配設的握持部時，使用者能以自己的手握持握持部並使移動車靠近身體，或遠離身體而簡便地調整位置，故使用性佳，並且在使就座部或護胸墊部轉動時，使用者可握持握持部並確實地保持身體，故安全性佳。而且，因握持部在水平面內轉動自如，故藉由在搭乘後將握持部朝前方轉動使得握持部不會妨礙使用者的姿勢，可在前傾時以護胸墊部確實地支撐使用者的體重，不僅支撐的穩定性、確實性佳，也能僅藉由使握持部轉動而對應移乘時與移動時的兩個動作，故通用性佳，零件數量少且量產性佳。
    握持部能以金屬製或合成樹脂製的管子(pipe)等形成。而且，握持部的形狀可適宜選擇，惟形成U字形或倒U字形者較易握持，故適合被使用。藉由在形設於護胸墊部的插通部插通握持部的一端側，可令握持部為轉動自如。此外，對插通部藉由以螺絲固定或銷嵌合等固定握持部，可依照使用者的體格或姿勢、用途等調整握持部的高度。
    而且，可在握持部安裝用以操作移動車的駕駛或就座部的上下移動或轉動的開關或桿(lever)等。
    當具有配設於台部的前方或側方，保護使用者的腳部的至少一部分之腳部保護部時，可保護膝蓋或腿肚(calf)等的前面或兩側面，故安全性佳。
    腳部保護部的形狀可適宜選擇。也可以在台部的前方或側方立設面狀、柵狀、格子狀等的框架(frame)以包圍使用者的周圍，且直接保持使用者的腳部，不使其移動於橫向或前後方向而固定也可以。當保持使用者的腳部時，除了護胸墊部或就座部外，也能透過腳部保護部支撐使用者的體重的一部分，可分散支撐使用者的體重，故特別是即使是接近立位姿勢的狀態也能穩定維持使用者的姿勢，故使用性佳。此時腳部保護部具有水平剖面形成略半圓弧形或略U字形的缺口狀的兩個膝蓋抵接部，以便保持各個腳的前面及兩側面者適合被使用。特別是為了柔軟地支撐使用者的膝下(脛骨的上端)部分，以胺甲酸乙酯等的彈性構件形成膝蓋抵接部或腳部保護部全體者，或部分地將彈性體(elastic body)包覆於膝蓋抵接部的抵接面者較佳。

(1) The protective chair with the transfer function (Patent Document 1) has a backrest at the back of the seat as with a normal chair, so the backrest is lowered until the seat is parallel to the backrest, or for a while. After the backrest is removed, the seat must be moved to the bed, the height of the seat is adjusted to the height of the bed, and the seated person is placed on the seat, the seat is raised, and the bed is pulled out with the transfer. The function of the whole chair is a problem, and the program is complicated and lacks usability.
Further, there is a problem that the backrest is pressed by the backrest in the use state, and is particularly unsuitable for use by a person with spinal cord injury.
(2) The protective human body moving device of Patent Document 2 can be formed in a double-opening by a shaft disposed at the center of the rear portion, and is brought into contact with an open chair by the rear of the waist of the displaced person, and the caretaker It is necessary to raise the left and right thighs of the occupant while interacting, and insert the seat into the buttocks, which is troublesome for the caregiver, lacks usability, and the structure of the chair is complicated and lacks mass production.
Further, since the seat is divided into right and left sides, the strength is likely to be insufficient, and it is difficult to reliably support the weight of the caregiver, and the problem of durability and stability of weight support is lacking.
(3) These conventional wheelchairs, which are headed by (Patent Document 3), have a backrest at the rear of the seating portion, and must be moved up and down from the front, so it is necessary to stand up for a moment to change the direction of the body and sit down. When transferring from a toilet seat such as a bed or a toilet, it is often necessary to resort to a caregiver.
In particular, when a careless person who is inconvenient and in need of care is transferred between a bed, a wheelchair, etc., such as a person with a long illness or an elderly person with a weak leg and a weak waist, the caregiver cuddles the care recipient, or the use is called When the caregiver cuddles the care recipient and supports the weight, the burden on the caregiver is large, which may cause back pain and the like. Further, in the case of getting on and off a wheelchair, there is a case where a balance or the like is lost and a fall accident occurs, so that the usability is lacking.
(4) Further, in (Patent Document 1) to (Patent Document 3), since the backrest is also pressed by the backrest, particularly in the case of a patient with a spinal cord injury, if the feeling is lost due to the spinal cord injury, the pain of the body cannot be felt. Sometimes blood flow is blocked and so on. Further, in the wheelchair seat posture of the spine-injured patient, the posture in which the spine is bent backwards greatly tilts the pelvis, and it tends to concentrate on the narrow range as compared with the healthy person, so it is necessary to pay special attention to the seat posture.
Moreover, there is a problem of giving back to the back due to the backrest in use, and in particular, there is a problem that is not suitable for patients suffering from spinal injuries.
The present invention has been made to solve the above problems, and an object thereof is to provide a simple transfer between a bed, a toilet seat, a wheelchair, and the like without changing the direction of the body, and the structure is simple and can be used even by one person, and is not used. The load on the back or the waist can be used for a long time, and even if it is damaged in the case of the spine, it can be used without being forced, which not only greatly reduces the burden on the caregiver and the care recipient (user), but is not limited to For the elderly or the physically handicapped, a healthy child can easily use a mobile car that is functional, stable, versatile, and operability for long-distance movement instead of a bicycle, a locomotive, or a wheelchair.
In order to solve the above-described conventional problems, the mobile vehicle of the present invention has the following configuration.
The mobile vehicle according to the first aspect of the present invention has a configuration in which a user transfers a bicycle to use a bicycle, a locomotive, or a wheelchair to perform indoor and outdoor movements.
a table portion having a traveling portion; a seating portion that is disposed on the table portion and that is movably held in a front-rear direction and an up-and-down direction with respect to the table portion and that is seated by a rear or a side of the user; a chest pad portion of the chest of the user is abutted on a distal end side of the seat portion; and the seat portion and the chest pad portion are moved back and forth and moved up and down to a lower position of the table portion and the table A drive mechanism portion that moves between the front high positions of the portion.
With this configuration, the following effects can be obtained:
(1) There is no backrest in the seat, and it can be up or down from the back or side of the table. It is not necessary to disassemble the seat or deform the seat when transferring, especially if the user is weakened by the legs and waist. In this case, it can be easily seated by the rear of the platform from the seat by the seat in the state of the bed or the toilet seat without changing the body, and it is possible to transfer by one person without the help of the designer's hand. The weight of the supporter (user) supported by the pedestal is difficult to occur, and the burden on the caregiver and the caregiver (user) is greatly reduced. Therefore, the labor-saving ability is good.

    台部2透過具有當作行走部3的前輪的兩個驅動輪3a與兩個後輪3b使得穩定性佳，並且藉由以前輪當作驅動輪3a使得使用者容易想像移動車1的行進方向，故操作性佳。而且，藉由加大行走部3的前輪的驅動輪3a的直徑，可容易越過段差等，故行走性佳。此外，行走部3的後輪3b作成與驅動輪3a相同的大小也可以。而且，藉由使使用者的腳著地的台部2的頂面2a比使用者的肩寬還寬，作成平面，在移乘時不會妨礙腳的移動，故使用性佳。
    在本實施的形態中，驅動輪3a的動力部使用可正反旋轉的馬達。而且，對各個驅動輪3a內裝一個馬達，可各自獨立控制轉速或旋轉方向。乃因可透過左右的驅動輪3a的轉速差進行右轉或左轉，或者透過左右的驅動輪3a的旋轉方向的不同當場進行右旋轉或左旋轉，故機動性佳。此外，驅動輪3a的轉速或旋轉方向等的操作可藉由配設於握持部24的加速器桿(accelerator bar)或煞車桿(未圖示)、配設於護胸墊部23的開關(未圖示)等進行。
    藉由將成為動力部或動力源的電池與驅動輪3a一起配設於台部2的前方，於在使用者就座的狀態下就座部22下降或後傾，重心朝台部2的後方移動時，該等構件可當作重錘發揮使台部2水平地穩定的作用。此外，藉由令電池為裝卸自如，可由移動車1卸下並進行充電。而且，若在護胸墊部23的頂面等配設電池量表(battery gauge)，則能以目視簡單地確認電池容量，故使用性佳。
    此外，行走部3不是被限定於本實施的形態者，也能使用輪內馬達當作行走部。可提供可藉由使用輪內馬達，無須在台部上配置馬達或連結軸等的空間，可大大地確保台部上的空間，故容易確保就座部的下側的空間，也可藉由降低就座部的位置提高穩定性，且可寬廣地得到放腳的空間等穩定性、居住性佳的移動車。行走部若為可使台部2移動(行走)者即可。例如具備履帶也可以，且具備多足步行的腳部等也可以。
    驅動機構部10在使就座部22下降到與床或馬桶座等的移乘對象同程度的高度時，就座部22的後端為與台部2的後端部同程度或比台部2的後端還突出於後方而配置。據此，可不將台部2的後部朝移乘對象的下部插入而使移乘對象與就座部22接近，可使使用者滑移而簡便地進行移乘，故通用性、使用性佳。藉由連桿驅動部20使用油壓氣缸或氣壓氣缸等，緊密且能移動重的物品，可進行控制且無噪音而能平順地使其動作。
    就座部22的形狀如圖2所示，由上看的形狀形成寬度由頂端緩緩地擴大到中央附近，隨著由中央附近進行到後方以更大的比例擴大寬度的尖頭型(自行車的鞍形狀)，在移乘時不會造成妨礙，且在使就座部22上升並採取立位姿勢時不會妨礙大腿部的操作。此外，就座部22的形狀不是被限定於此，可選擇使用者容易跨過的任意的形狀，例如可形成與葫蘆型或乘馬用的鞍等一樣的形狀。
    此外，在本實施的形態中雖然將就座部22的插通部22a插通於立設於第三連結轉動軸13的支柱21，以固定操作部22b透過螺旋夾鉗滑動自如地固定就座部22，但就座部22固定於轉動軸保持部10a的頂面也可以。而且，支柱21也能與轉動軸保持部10a一體形成。
    護胸墊部23以具有柔軟性、彈力性的材質形成，以便不給予使用者的胸部部分的壓迫或難受的感覺。此外，護胸墊部23的材質或形狀可依照使用者的體格等選擇面積、形狀、硬度等。
    握持部24以金屬製或合成樹脂製的管子形成倒U字形，將一端側可固定左右方向的轉動角而插通於護胸墊部23的卡合孔23b。據此，可依照需要在水平面內使握持部24轉動，可使握持部24移動至護胸墊部23的側方或前方位置等的容易抓握的位置而使用。此外，藉由在握持部24的端部安裝作為防滑用的橡膠製的手柄(grip)，將胸部按壓於護胸墊部23的使用者可確實地握持握持部24的端部，可保持輕鬆的姿勢。
    腳部保護部25的下端部被嵌裝固定於使第一連結轉動軸11的兩端部彎曲的彎曲部11a。據此，可使腳部保護部25與第一連結轉動軸11一起轉動。而且，在腳部保護部25形成水平剖面為略半圓弧狀或略U字形且後方敞開的兩個膝蓋抵接部25a。據此，可保護使用者的兩腳的膝下(脛骨的上端)部分的前面及兩側面。而且，因可支撐使用者的體重的一部分，且在橫向及前後方向腳不會移動而保持，故可穩定維持立位姿勢或前傾姿勢，特別是可保護膝蓋並減輕其負擔，故使用性佳。此外，當在膝蓋抵接部25a的基部與表皮之間放入胺甲酸乙酯泡沫等的彈性構件時可緩和移動車1的移動時的振動或碰撞、神經的壓迫等。
    腳部保護部25的形狀不是被限定於本實施的形態者，也可以在台部2的前方或側方立設面狀、柵狀、格子狀等的框架以包圍使用者的周圍。
    其次，針對由移乘對象移乘到實施的形態一的移動車時的使用方法進行說明。
    圖5是顯示使用實施的形態一的移動車由馬桶座移乘前的狀態之模式側視圖，圖6是顯示使用實施的形態一的移動車由馬桶座移乘後的狀態之模式側視圖。
    圖5及圖6中，30為具備成為移乘對象的馬桶座30a的西式的便器，X為使用者。
    在圖5中使用者X在坐在馬桶座30a的狀態下以兩手握持握持部24，將移動車1拉到跟前直到移動車1的就座部22的後端與馬桶座30a接觸的程度，定位於最佳的位置，將兩腳放在台部2的頂面2a。此時，可依照需要藉由使握持部24轉動到跟前(台部2的後方側)，確實地握持握持部24。
    此外，藉由預先將驅動機構部10的連桿驅動部20伸長，使就座部22的高度下降到與使用者X所坐的馬桶座30a等的高度相同程度的位置，可容易進行由馬桶座30a移乘到就座部22。而且，藉由使附有腳輪的輔助框架4朝台部2的後方移動，使使用者X移乘時的穩定性佳。此外，附有腳輪的輔助框架4的連結軸4a、4b透過第二連結轉動軸12與齒輪或皮帶等的連桿組連接，配合驅動機構部10的第二連結轉動軸12的轉動而前後移動。
    接著如圖6所示，藉由一邊握持握持部24，一邊使臀部朝前方移動朝就座部22就座，以便將護胸墊部23拉到使用者X的胸部，使兩腳朝前方移動，完成在座位姿勢下的搭乘。
    此外，在本實施的形態中雖然是針對由便器30的馬桶座30a移乘到移動車1的情形進行了說明，但即使是移乘對象為床或輪椅等其他的情形，使用方法也相同。而且，當由移動車1移乘到移乘對象的床或馬桶座30a等時，以與上述的程序大致相反的順序進行動作也可以。
    接著，針對在實施的形態一的移動車的立位姿勢的使用方法進行說明。
    圖7是顯示以實施的形態一的移動車由座位姿勢移至立位姿勢的狀態之模式側視圖。
    若由圖6的狀態，使用者X操作操作桿(未圖示)等並驅動驅動機構部10，則如圖7所示，就座部22或護胸墊部23一邊轉動到前方一邊上升，使使用者X移至立位姿勢。此時，為了保持台部2上的重量平衡，附有腳輪的輔助框架4透過前述的連桿組，伴隨著第二連結轉動軸12的旋轉而朝台部2的前方移動。
    此外，就座部22的高度調整到膝蓋緩緩地彎曲的程度，以便能以就座部22、護胸墊部23、腳部保護部25分散支撐使用者X的體重較佳。而且，腳部保護部25以棘輪機構或螺旋夾鉗等調節角度，以便使用者X的膝下附近抵接膝蓋抵接部25a且被保持較佳。
    可藉由使用者X解除移動車1的煞車，操作加速器桿等而移動。
    接著，針對在實施的形態一的移動車的前傾姿勢下的使用方法進行說明。
    圖8是顯示實施的形態一的移動車的前傾姿勢之模式側視圖。
    在圖8中，可藉由使用棘輪機構或螺旋夾鉗等使支柱21繞第三連結轉動軸13轉動並固定，使就座部22及護胸墊部23前傾而將使用者X的體重落於護胸墊部23，特別是可大幅減輕脊椎有損傷的使用者X的負擔，能以輕鬆的姿勢長時間搭乘，故使用性、通用性佳。此外，藉由在轉動軸保持部10a與就座部22的底部之間配設連桿組或活塞氣缸(piston cylinder)等並進行就座部22的角度調整或固定也可以。
    如以上因構成實施的形態一中的移動車，故可得到如下的作用。
    (1)、就座部無靠背，可由台部的後方或側方上下，在移乘時無須分解就座部或使就座部變形，特別是使用者為腿和腰等衰弱的被介護者的情形，可由就座於床或馬桶座等的狀態不改變身體的方向下容易由台部後方跨過就座部而就座，無須藉助介護者的手就能一個人進行移乘，可藉由台部支撐被介護者(使用者)的體重，跌倒等很難發生，可大幅減輕介護者及被介護者(使用者)的負擔，故省力性、使用性佳。
    (2)、因具有立設於就座部的前端側，抵接使用者的胸部之護胸墊部，故可藉由以前傾姿勢抱住護胸墊部而放置體重，可藉由就座部及護胸墊部分散體重而確實地支撐使用者的身體，即使無靠背也能以穩定的姿勢維持長時間的座位姿勢或立位姿勢或者進行移動，可減輕給予使用者的背部或腰等的負擔，故安全性、使用性佳。
    (3)、藉由使護胸墊部抵接使用者的胸部，可描繪脊椎透過頸椎而前彎、透過胸椎而後彎、透過腰椎而前彎的S字形的曲線，且可採取接近骨盤稍微前傾的正常的立位姿勢的姿勢，可保持體重均勻地分散於坐骨結節的理想的座位姿勢，可減輕使用者的負擔，故長時間的連續使用性佳。
    (4)、因藉由具有使就座部及護胸墊部繞與台部的前後方向正交的水平軸轉動之驅動機構部，可依照床或馬桶座等的移乘對象物的高度或使用者的體格或姿勢等使就座部或護胸墊部的位置移動於前後方向或上下方向而進行調整，可使移乘對象物與就座部接近，故可一個人簡便地進行移乘動作，即使是在移乘對象物的下部無台部的插入空間的情形也能使用，故通用性佳。
    (5)、因可藉由驅動機構部使就座部或護胸墊部朝前後方向轉動，故可一邊使就座部或護胸墊部後傾一邊下降，且使用者可安全且簡便地上下，並且可藉由一邊使就座部或護胸墊部前傾一邊上升，將使用者保持於所需的姿勢(角度)，或抬起到所需的高度，能以使用者的輕鬆的姿勢進行移動，故使用性佳。
    (6)、由於是無靠背，使用者的背面(就座部的後方)被敞開的背面敞開型，故當使用者為脊椎或腰椎等背部或腰有損傷的患者時，仍舊可容易由背面(背部)進行診察，無須朝床等移動，可減輕使用者的負擔，並且可縮短診察所需的時間，故診察的作業性佳。
    (7)、因台部具有行走部，故不限於老人或肢體行動不便者等，健康的小孩到大人廣泛的使用者可簡單地使用以取代腳踏車、機車、輪椅等而進行在戶內、戶外的移動。
    (8)、因可藉由驅動機構部使就座部上升並以接近立位的姿勢移動(行走)，故與習知的輪椅比較，使用者可確保寬廣的視野，來自他人的能見度也高，可避免碰撞等的事故，安全性佳並且可防止血流的惡化，可使用以取代輪椅而進行長距離的移動，故使用性佳。
    (9)、因可藉由驅動機構部使就座部或護胸墊部上升，或使護胸墊部前傾，故手也搆得到在習知的輪椅所不及的地方，也能簡便地進行將東西取出和放入到高處或門的開關、洗臉或烹調等，可擴大作業範圍，故功能性佳。
    (10)、可藉由驅動機構使就座部升降，使使用者的髖關節、膝關節、踝關節等運動，即使是一個人也能進行利用屈伸運動的下半身的關節可動域的擴大或肌肉力量增強、血流的改善等的復健，可防止下半身的運動功能的降低或水腫等，故功能性、省力性佳。
    (11)、因驅動機構部具有配設於台部之前後兩處的第一、第二連結轉動軸，與配設於就座部的下部之前後兩處的第三、第四連結轉動軸，第一連結轉動軸與第三連結轉動軸及第二連結轉動軸與第四連結轉動軸各自藉由具有一個以上的連桿軸的前方連桿部及後方連桿部連結，故可藉由使兩端部被轉動自如地連結於前方連桿部及後方連桿部的連桿驅動部伸縮，在保持一定的第一、第二連結轉動軸間及第三、第四連結轉動軸間的距離下，前方連桿部及後方連桿部與台部頂面所成的角度變化，一邊使配置於第三、第四連結轉動軸的上方的就座部朝前後方向轉動，一邊使其上下移動，能以比藉由直動式的油壓或氣壓氣缸等直接使就座部上下移動還小的衝程進行廣泛的高度調整，可謀求驅動機構部的小型化、輕量化。
    (12)、因就座部藉由前方連桿部及後方連桿部在前後兩處被支撐，故可確實地支撐使用者的體重，降低移動時的振動的產生，故姿勢的穩定化佳。
    (13)、因就座部及護胸墊部被滑動自如地配設於立設於第三連結轉動軸的支柱，故可依照使用者的體格等使就座部或護胸墊部的位置上下移動，可擴大就座部或護胸墊部的可動範圍，故通用性佳。
    (14)、因在護胸墊部的至少一側部具有在水平面內被轉動自如地配設的握持部，被看護者可透過以自己的手握持握持部並使移動車靠近身體，或遠離身體而簡便地調整位置，故使用性佳。
    (15)、因在使就座部或護胸墊部移動時，被看護者握持握持部且可確實地保持身體，故安全性佳。
    (16)、因握持部在水平面內轉動自如，故藉由在搭乘後將握持部朝前方轉動使得握持部不會妨礙使用者的姿勢，可在前傾時以護胸墊部確實地支撐使用者的體重，故支撐的穩定性、確實性佳。
    (17)、可僅藉由使握持部轉動而使其移動至對應移乘時與移動時的兩個動作的最佳位置，故通用性佳，零件數量少且量產性佳。
    (18)、因具有配設於台部的前方，保持使用者的腳部的至少一部分的腳部保護部，故除了護胸墊部或就座部外，也能透過腳部保護部分散支撐使用者的體重，特別是即使是接近立位姿勢的狀態也能穩定維持使用者的姿勢，故使用性佳。
    (19)、可藉由配設於台部的前方的腳部保護部保護膝蓋或腿肚等的前面或兩側面，故安全性佳。
    (20)、因在台部的兩側部具有與台部的縱向平行被前後移動自如地配設的附有腳輪的輔助框架，故可藉由依照使用者的姿勢(重心位置)使輔助框架前後移動，不使台部摔倒而保持平衡，故安全性佳。
    (21)、在不使用時，讓台部與附有腳輪的輔助框架重疊而使附有腳輪的輔助框架移動，可縮短全長並緊密地收納，故運送性、省空間性佳。
    (實施的形態二)
    圖9是顯示使實施的形態二中的移動車的就座部下降的狀態之模式側視圖。此外，對與實施的形態一一樣的構件附加同一的符號，省略說明。
    圖9中實施的形態二中的移動車1A與實施的形態一不同者為以下的幾點:使用利用使就座部22及護胸墊部23上下移動的油壓氣缸或氣壓氣缸等的活塞氣缸20A的驅動機構部10A，取代使就座部22及護胸墊部23轉動及上下移動的四連桿組的驅動機構部10；轉動軸保持部10b一體形設於就座部22的下部；支柱21透過連結轉動軸13a被轉動自如地保持於轉動軸保持部10b。
    在本實施的形態中雖然驅動機構部10A使用活塞氣缸20A，惟不是被限定於此，也可以使用組合齒條與小齒輪者、伸縮鐵等的連桿組、滾珠螺桿等的升降手段。而且，就座部22或護胸墊部23的傾動(tilting)、固定也可以透過棘輪機構或螺旋夾鉗等以手動進行。
    而且，驅動機構部10A不限於使就座部22或護胸墊部23上下移動於垂直方向者，也能由台部2的後方低位置到前方高位置使就座部22或護胸墊部23移動於斜的方向，也能同時進行前後移動及上下移動。此情形，能以一次的動作迅速地使就座部22移動至最適於移乘或上下、移動(行走)的位置，故省力性、使用性佳。而且，因在台部2的後方低位置與前方高位置之間使就座部22移動時，可將使用者的體重落於並支撐於前方的護胸墊部23，故可不失去平衡而安全地進行前後移動及上下移動，無落下或跌倒之虞，任何人都能放心簡單地使用，動作的穩定性、可靠度佳。
    此外，實施的形態二的移動車1A的使用方法因與實施的形態一的移動車1一樣，故省略說明。
    如以上因構成實施的形態二中的移動車，故除了在實施的形態一得到的(1)至(3)、(6)至(8)、(14)至(21)的作用外，還可得到如下的作用。
    (1)、因可藉由具有使就座部及護胸墊部移動於台部的上下方向的驅動機構部，依照床或馬桶座等的移乘對象物的高度或使用者的體格或姿勢等自在地調整就座部或護胸墊部的位置，可使移乘對象物與就座部接近，故可一個人簡便地進行移乘動作，即使是在移乘對象物的下部無台部的插入空間的情形也能使用，故通用性佳。
    (2)、因可藉由驅動機構部使就座部及護胸墊部上下移動，故在使就座部及護胸墊部下降並使使用者移乘後，可藉由使就座部或護胸墊部上升，抬起到所需的高度，能以使用者的輕鬆的姿勢進行移動，故使用性佳。
    (3)、因可藉由驅動機構部使就座部及護胸墊部上升，故手也搆得到在習知的輪椅所不及的地方，也能簡便地進行將東西取出和放入到高處或門的開關、洗臉或烹調等，可擴大作業範圍，故功能性佳。
    (4)、可僅藉由活塞氣缸簡便且確實地使就座部上下移動，對床或馬桶座等的移乘對象的就座部的高度調整容易且使用性佳。
    (5)、因就座部藉由活塞氣缸僅進行上下移動，故重心位置不會前後大大地變化，無須利用附有腳輪的輔助框架進行的平衡調整，故使用性佳。
    (6)、可藉由使用活塞氣缸，降低零件數量，簡化驅動機構部的構成，謀求小型化、輕量化，故量產性、維修保養性佳。
    (7)、可藉由使護胸墊部前傾，將使用者的體重落於護胸墊部，特別是可大幅減輕脊椎有損傷的使用者的負擔，能以輕鬆的姿勢長時間搭乘，故使用性、通用性佳。
    (實施的形態三)
    圖10是顯示使實施的形態三的移動車的就座部下降的狀態之模式俯視圖，圖11是顯示以立位姿勢搭乘實施的形態三的移動車的狀態之模式側視圖，圖12是顯示使用實施的形態三的移動車移乘到馬桶座前的狀態之模式側視圖。此外，對與實施的形態一或二一樣的構件附加同一的符號，省略說明。
    在圖10至圖12中，實施的形態三中的移動車1B與實施的形態一不同者為以下的幾點:行走部3的驅動輪3a小小地形成；在台部2的頂面2a之上具備被滑動自如地配設於前後方向的踏板部2d；具備被轉動自如地保持於就座部22的後端部的護腰墊部22c。
    在圖10中，踏板部2d被承載於台部2的頂面2a，藉由左右兩側部導引並滑動於前後方向。藉由在踏板部2d的底面或左右的兩側部配設車輪或滾輪等，可平順地使踏板部2d滑動。此外，踏板部2d即使只是使用者X放置腳且加上體重，也能配合使用者X的身體的前後移動而使其移動，惟若與就座部22連動且前後移動，則動作的穩定性、使用性佳。為了使就座部22與踏板部2d的動作連動，例如配合驅動機構部10的連桿驅動部20的伸縮並使驅動踏板部2d的車輪的馬達正反旋轉的話即可。此外，在本實施的形態中雖然是水平地配置踏板部2d，惟當後方變低使其傾斜而配置時，在移動到後方時踏板部2d的高度變低，可容易進行上下，故使用性佳。而且，當使踏板部2d與就座部22一起上下移動時，可保持一定的就座部22與踏板部2d的距離，不管就座部22的高度，可一直以踏板部2d支撐使用者X的腳，故安全性、使用性佳。
    而且在圖10中，護腰墊部22c的下端部被轉動自如地保持於就座部22的後端部。藉由護腰墊部22c可繞與台部2的前後方向正交的水平軸轉動，可使護腰墊部22c對就座部22轉動到所需的角度。
    當以立位姿勢進行移動時，如圖11所示，藉由使就座部22移動到前方或上方，並且將護腰墊部22c豎立於垂直方向，能以護腰墊部22c安全地支撐使用者X的臀部附近，故安全性佳。
    其次，當在與馬桶座30a等的移乘對象之間進行移乘時是如圖12所示，藉由使就座部22移動到後方或下方，並且使踏板部2d移動到後方，使用者X不會失去平衡而能平順地使身體全體移動。而且，藉由將護腰墊部22c放倒於水平方向(後方)，使得護腰墊部22c不會造成妨礙，可平順地進行移乘動作，故使用性佳。特別是如圖12所示，當無法充分地使就座部22與移乘對象的馬桶座30a接近時，可藉由將護腰墊部22c放倒於後方而解除該間隙並在就座部22與馬桶座30a之間平順地進行移乘作業，故使用性、通用性佳。而且，即使是無法使就座部22與移乘對象成相同高度而產生段差的情形，也可藉由護腰墊部22c解除該段差。
    護腰墊部22c的轉動動作以電動進行也可以，且以手動進行也可以，惟可透過電動化以簡便的操作使其轉動至所需的角度，故操作性、省力性佳。特別是當連動於就座部22的前後移動及上下移動，自動地進行護腰墊部22c的轉動時，無須麻煩的操作，不會有在將護腰墊部22c放倒於後方下開始移動，故安全性、操作性佳。
    此外，即使是以就座姿勢進行移動(行走)的情形也能藉由豎立護腰墊部22c，在起動時或加速時等安全地支撐使用者X，故可靠度佳。
    如以上因構成實施的形態三中的移動車，故除了在實施的形態一得到的作用外，還可得到如下的作用。
    (1)、因具有被轉動自如地保持於就座部的後端側的護腰墊部，故藉由在進行上下(移乘)於就座部時將護腰墊部放倒於水平方向，護腰墊部不會造成妨礙，藉由在就座於就座部並進行移動時將護腰墊部豎立於垂直方向，可支撐使用者的臀部或腰部，在起動時或加速時等可確實地防止由就座部落下，故使用性、安全性佳。
    (2)、使就座部移動到後方或下方，在與床與馬桶座等的移乘對象之間移乘時，無法充分地使就座部與移乘對象接近，當產生間隙時或無法使就座部與移乘對象成相同高度而產生段差時等，可藉由將護腰墊部放倒於後方而解除該間隙或段差，可在就座部與移乘對象之間平順地進行移乘作業，故使用性、通用性佳。
    (3)、因藉由在台部具有被滑動自如地配設於前後方向的踏板部，在使就座部前後移動時，可在使用者將腳承載於踏板部下使身體全體前後移動，故無須使腳懸起或無須使用者自身使腳前後移動，重心的穩定性、使用性佳。
    (4)、因在使就座部移動到後方，在與床或馬桶座等的移乘對象之間移乘時，可使踏板部靠近移乘對象，故可平順地使體重移動而進行移乘動作，使用性佳。
    (實施的形態四)
    圖13是顯示在台部的前方使實施的形態四的移動車的就座部下降的狀態之模式斜視圖，圖14是顯示在台部的後方使實施的形態四的移動車的就座部下降的狀態之模式側視圖，圖15是顯示在台部的前方使實施的形態四的移動車的就座部上升的狀態之模式側視圖，圖16是實施的形態四的移動車之模式前視圖，圖17是由實施的形態四的移動車的後方看之模式斜視圖。此外，對與實施的形態一至三一樣的構件附加同一的符號，省略說明。
    在圖13至圖17中，實施的形態四中的移動車1C與實施的形態一的移動車1A不同者為以下的幾點:具有具備輪內馬達3c的行走部3A以取代行走部3；具有配設於台部2的前方的前部輔助輪3d與配設於台部2的後方的後部輔助輪3e；具備藉由活塞氣缸20A驅動，使就座部22及護胸墊部23及後述的框架部41上下移動之上下驅動機構部10c，與藉由活塞氣缸20B驅動，使就座部22及護胸墊部23及後述的框架部41前後移動之前後驅動機構部10d之驅動機構部10B，以取代驅動機構部10。
