また、座部退避姿勢において、ガイドローラ96がカム溝95の下端縁部に当接すると共にカム溝95の水平状部に対応して、揺動部材91が保持されている。 Then, as shown in FIG. 3, a hooking member 93 is protruded from the columnar part 87 via a guide roller 96, and the hooking member 93 and a protruding piece 9g provided on the leading edge 9a of the seat part 9 are provided. Are connected by a flexible wire 92 made of metal such as a wire.
In the seat retracted posture, the tip edge 9a (projection piece 9g) is pulled downward by the tension of the flexible wire 92, and the seat 9 is held in an upright posture with the tip tilted downward.
In the seat retracted posture, the guide roller 96 abuts on the lower end edge of the cam groove 95 and the swinging member 91 is held corresponding to the horizontal portion of the cam groove 95.

座部退避姿勢（図５参照）から、介護者が座部９を左右内方へ揺動させると、外筒部91ａが鉛直状軸心Ｌｚ廻りに回転され、ガイドローラ96に、カム溝95の傾斜部が対応する。すると、カム溝95に沿って揺動部材91は自重により降下しつつ鉛直状軸心Ｌｚ廻りに揺動する。揺動部材91の降下に伴って、可撓線材92が緩み、その緩み代だけ、座部９の自重により（自動で）基端縁部９ｂが倒れるように水平状軸心Ｌｙ廻りに揺動して、座部着席可能姿勢（図６参照）になる。
つまり、カム溝95の傾斜部がガイドローラ96が対応すると、自重によって座部９は、左右内方乃至前方へ向って鉛直状軸心Ｌｚ廻りに揺動すると共に水平面状姿勢へ揺動する。 When the caregiver swings the seat 9 in the left and right inward from the seat retracted posture (see FIG. 5), the outer cylinder 91a is rotated about the vertical axis Lz, and the guide roller 96 is provided with the cam groove 95. Corresponds to the inclined portion. Then, the swing member 91 swings around the vertical axis Lz while being lowered by its own weight along the cam groove 95. As the swing member 91 is lowered, the flexible wire 92 is loosened, and the base edge 9b is swung around the horizontal axis Ly so that the base end portion 9b is tilted by the weight of the seat 9 only by the looseness. As a result, the seat portion can be seated (see FIG. 6).
That is, when the guide roller 96 corresponds to the inclined portion of the cam groove 95, the seat portion 9 swings around the vertical axis Lz from the left and right inward to the front by its own weight, and swings to a horizontal plane posture.

また、座部着席可能姿勢（図６参照）から、介護者が水平面状の座部９を左右一方側（左右外方）へ揺動させると、外筒部91ａが鉛直状軸心Ｌｚ廻りに回転され、カム溝95の傾斜部によって揺動部材91が上昇する。揺動部材91の上昇に伴って、座部９の先端縁部９ａに可撓線材92のテンションが作用して突片９ｇを下方へ引き寄せ、その引き寄せによって基端縁部９ｂが起き上がる起立状姿勢に揺動し、座部退避姿勢（図５参照）になる。 In addition, when the caregiver swings the horizontal plane seat 9 from the seating seatable posture (see FIG. 6) to the left and right sides (left and right outwards), the outer cylinder 91a moves about the vertical axis Lz. The rocking member 91 is raised by the inclined portion of the cam groove 95 by being rotated. As the swing member 91 rises, the tension of the flexible wire 92 acts on the distal end edge 9a of the seat 9 to draw the protruding piece 9g downward, and the proximal end edge 9b is raised by the drawing. Swings to a seat retracted posture (see FIG. 5).

即ち、座部９の水平面状姿勢と起立状姿勢との切換えは、介護者が座部９を鉛直状軸心Ｌｚ廻りに揺動させれば、座部９に水平状軸心Ｌｙ廻りに揺動させる操作力を付与せずとも、自動で、水平面状姿勢と起立状姿勢とに切り替わる。 That is, switching between the horizontal plane posture and the upright posture of the seat portion 9 is performed when the caregiver swings the seat portion 9 about the vertical axis Lz and swings the seat portion 9 about the horizontal axis Ly. Even if the operating force to be moved is not applied, it automatically switches between a horizontal plane posture and an upright posture.

また、座部９が水平面状姿勢となった位置で、座部９の水平状軸心Ｌｙ廻りの揺動を阻止するストッパ機構を備えている。
ストッパ機構は、図３に示すように、支持部91ｂからラジアル外方（下方）へ突設されたストッパ部98と、座部９の円筒部90の外周筒壁部に周方向に沿って貫設された長孔99と、を備え、座部９が水平面状姿勢となった際に、長孔99の一端縁99ａにストッパ部98が当接して、円筒部90の水平状軸心Ｌｙ廻りの回動を阻止して、座部９が後方下傾状となるのを阻止する（水平面状に保持する）。 In addition, a stopper mechanism is provided that prevents the seat portion 9 from swinging around the horizontal axis Ly at a position where the seat portion 9 is in a horizontal plane.
As shown in FIG. 3, the stopper mechanism penetrates the stopper portion 98 projecting radially outward (downward) from the support portion 91 b and the outer peripheral cylindrical wall portion of the cylindrical portion 90 of the seat portion 9 along the circumferential direction. When the seat portion 9 is in a horizontal plane posture, the stopper portion 98 abuts on one end edge 99a of the long hole 99, and the cylindrical portion 90 rotates around the horizontal axis Ly. To prevent the seat portion 9 from tilting backward (holding in a horizontal plane).

また、図４乃至図７に示すように、フック部23にて左右外方への抜けが防止されるようにベルト掛け部24に懸架される（引っ掛けられる）Ｕ字状ベルト部20ｂと、ベルト部20ｂに接続され身体弱者の背部（腰部乃至肩甲骨近傍）を支持するためのパッド部20ａと、を有するスリング部材20を備えている。 Also, as shown in FIGS. 4 to 7, a U-shaped belt portion 20b suspended (or hooked) on the belt hanging portion 24 so as to prevent the hook portion 23 from coming off to the left and right outwards, and a belt A sling member 20 having a pad portion 20a connected to the portion 20b and supporting the back of the weak body (the waist or the vicinity of the scapula).

また、図２と、図４乃至図７に二点鎖線で簡略して図示するが、下枠部81の前部に、フットペダルにて操作可能なフロアロック機構10を設けている。フットペダルを操作することで、押圧部材が、床面（車輪走行面）Ｇに押圧し、車輪80による走行を阻止するようにしている。なお、図１においては、フロアロック機構10は図示省略している。 2 and 4 to 7, the floor lock mechanism 10 that can be operated with a foot pedal is provided at the front portion of the lower frame portion 81. By operating the foot pedal, the pressing member presses against the floor surface (wheel travel surface) G, and travel by the wheels 80 is prevented. In FIG. 1, the floor lock mechanism 10 is not shown.

また、移動車全体として、耐水性を有するように、各部品を、樹脂製やステンレス製の製作品や市販品、防錆処理や防水処理を施した製作品や市販品を組み合わせて製作し、身体弱者を乗車させたまま洗髪やシャワーを浴びることを可能としている。 In addition, as a whole moving vehicle, each part is manufactured by combining resin and stainless steel products and commercial products, rust-proof and waterproof products and commercial products, It makes it possible to wash hair and take a shower with a weak person on board.

次に、本発明の移動車の作用（使用方法）について説明する。
先ず、図４に示すように、ベッドの側縁や車椅子等に着席している身体弱者の正面に配設し、フロアロック機構10をフットペダル操作してロック状態にし、車輪80による走行を阻止する（床面Ｇに固定する）。 Next, the operation (usage method) of the mobile vehicle of the present invention will be described.
First, as shown in FIG. 4, it is arranged in front of a weak person sitting on the side edge of a bed or a wheelchair, etc., and the floor lock mechanism 10 is locked by operating the foot pedal to prevent the wheel 80 from running. (Fixed to the floor G).

そして、ステップ部材３に足を載置させると共に、下腿支持部材７の弯曲凹状部70に身体弱者の下腿部を当接させる。また、身体弱者に持ち手部21を把持させる。
ステップ部材３は前方上傾状であるので、足首に負担をかけずに、足裏をステップ部材３に密着させることができる。
また、下腿支持部材７は、第４左右水平状軸心Ｌｄ廻りに揺動して、身体弱者の体格に沿って密着する。 Then, the foot is placed on the step member 3 and the lower leg part of the weak body is brought into contact with the curved concave part 70 of the lower leg support member 7. Further, the weak hand is made to grip the handle portion 21.
Since the step member 3 is inclined forward and upward, the sole can be brought into close contact with the step member 3 without imposing a burden on the ankle.
Further, the crus support member 7 swings around the fourth horizontal axis Ld on the left and right sides and adheres closely along the physique of the weak body.

そして、スリング部材20を持ち上げ杆２と身体弱者に装着する。
スリング部材20のパッド部20ａを身体弱者の背部に当接させると共に、ベルト部20ｂを、身体弱者の脇下を通してベルト掛け部24の両端部に掛け、フック部23にて左右外方への抜けを防止する。パッド部20ａの当接位置は、肩甲骨近傍、腰部、臀部等自由である。 Then, the sling member 20 is lifted and attached to the heel 2 and the weak body.
The pad portion 20a of the sling member 20 is brought into contact with the back of the weak body, and the belt portion 20b is hung on both ends of the belt hook portion 24 through the armpit of the weak body, and the hook portion 23 is pulled out left and right. To prevent. The contact position of the pad portion 20a is free in the vicinity of the scapula, the waist, the buttocks, and the like.

そして、図示省略の介護者が、解除レバー14を操作して、伸縮部材５の伸縮ロックを解除し、伸縮ロック解除したまま（解除レバー14を操作したまま）、操作杆１のハンドル部11（先端部１ｆ）を矢印Ｅのように前方（下方）へ揺動操作する。 Then, a caregiver (not shown) operates the release lever 14 to release the expansion / contraction lock of the expansion / contraction member 5 and releases the expansion / contraction lock (while operating the release lever 14). The tip 1f is swung forward (downward) as indicated by an arrow E.

すると、図５に示すように、持ち上げ杆２の後端部２ｂ（ベルト掛け部24）が前方かつ上方へ移動し、持ち手部21も前方へ移動する。身体弱者は着席姿勢から上半身が前上方へ引き寄せられて起立姿勢となる。
さらに、吊り持ち連動杆４がステップ部材３の前端部３ａを降下させるので、身体弱者の体重（重心）が、前方へ移動しやすくなる。
また、ステップ部材３の揺動に連動して下腿支持部材７も降下し、身体弱者に常に当接（フィット）する。また、伸縮部材５は、伸長する。 Then, as shown in FIG. 5, the rear end 2b (belt hooking portion 24) of the lifting rod 2 moves forward and upward, and the handle portion 21 also moves forward. The weak body is in a standing posture with the upper body being drawn forward and upward from the seated posture.
Further, since the suspension interlocking rod 4 lowers the front end portion 3a of the step member 3, the weight (center of gravity) of the weak body can easily move forward.
Further, the lower leg support member 7 also descends in conjunction with the swinging of the step member 3, and always abuts (fits) the weak body. The elastic member 5 extends.

ここで、図４から図５に示すように、身体弱者を持ち上げる際にステップ部材３にかかる身体弱者の荷重は、吊り持ち連動杆４を引き下げる力となる。その力は、持ち上げ杆２の後端部２ｂを持ち上げる力となる。

The force is a force that lifts the rear end 2b of the lifting rod 2.
That is, the load (weight) of the weak body can be used as an operating force for lifting the weak body, and the burden on the caregiver who operates the operating rod 1 is reduced as the load of the weak body moves to the step member 3.

身体弱者を起立姿勢にした状態で、介護者（操作者）が解除レバー14の操作を止めると、伸縮部材５の伸縮が阻止され、持ち上げ杆２の揺動が阻止される。従って、介護者が操作杆１から手を離しても身体弱者の起立姿勢は保持される。この起立姿勢の際にスリング部材20に身体弱者は体重を掛けることで、足腰に負担がかからず姿勢が保持される。
なお、この起立姿勢での移動（走行）や待機も可能である。 If the caregiver (operator) stops the operation of the release lever 14 in a state where the weak body is standing, the expansion / contraction of the expansion / contraction member 5 is blocked and the swinging of the lifting rod 2 is blocked. Therefore, even if the caregiver removes his hand from the operation rod 1, the standing posture of the weak body is maintained. In this standing posture, the physically weak person puts his / her weight on the sling member 20, so that the posture is maintained without placing a burden on the legs and hips.
It is possible to move (run) or stand by in this standing posture.

そして、介護者が、座部９を鉛直状軸心Ｌｚ廻りに左右内方へ揺動させると、座部９が起立状姿勢から、図６に示すように、水平面状に姿勢に自動で切り替わる。
つまり、座部９が、座部退避姿勢から着席可能姿勢となる。そして、介護者が操作杆１のハンドル部11を把持すると共に解除レバー14を操作して、伸縮部材５の伸縮を解除し操作杆１を上後方へ揺動させると、持ち上げ杆２の後端部２ｂが降下し、伸縮部材５が短縮して、図７に示すように、身体弱者を座部９に着席させて、乗車が完了する。 Then, when the caregiver swings the seat 9 to the left and right inward about the vertical axis Lz, the seat 9 automatically switches from a standing posture to a horizontal posture as shown in FIG. .
That is, the seat portion 9 changes from the seat retracted posture to the seatable posture. When the caregiver grasps the handle portion 11 of the operation rod 1 and operates the release lever 14 to release the expansion and contraction of the elastic member 5 and swing the operation rod 1 upward and backward, the rear end of the lifting rod 2 The part 2b descends, the telescopic member 5 is shortened, and as shown in FIG. 7, the weak body is seated on the seat part 9, and the boarding is completed.

身体弱者の着席後に、解除レバー14の操作をやめ、フロアロック機構10のロックを解除し、操作杆１のハンドル部11を把持して牽引することで、車輪80にて走行でき移動させることができる。
身体弱者を降車させる場合（降車作業）は、上述の乗車作業と逆の手順で良く（図７、図６、図５、図４と、順次行えば良く）、ベッドから車イスへの移乗や、ベッドからベッドへの移載等も可能である。
また、座部９の中央部に貫通孔（窓部）を有する便座型とすることで、座部９の下方位置に仮設便器を配設して排泄を行うことも可能である。 After the weak person is seated, the operation of the release lever 14 is stopped, the lock of the floor lock mechanism 10 is released, and the handle 11 of the operation rod 1 is grasped and pulled, so that the vehicle can run and move on the wheel 80. it can.
