以下、図１〜図１０に基づいて本発明の実施の形態を説明する。尚、本明細書において、前後方向、左右方向（車幅方向）および上下方向とは、運転席に着座した乗員を基準として定義される。 Hereinafter, embodiments of the present invention will be described with reference to FIGS. In the present specification, the front-rear direction, the left-right direction (vehicle width direction), and the up-down direction are defined with reference to an occupant seated in the driver's seat.

図１に示すように、車両１１の前から２列目の左側のシート１２の左側面に後方にスライド可能なドア１３が対峙する。左側のシート１２の車幅方向外側面とドア１３の車幅方向内側面とに挟まれた空間に、車椅子と左側のシート１２との間で被介助者が移乗するのを補助する乗員移乗装置１４が配置される。 As shown in FIG. 1, a door 13 slidable rearward faces the left side surface of the left-side seat 12 in the second row from the front of the vehicle 11. An occupant transfer device that assists the person being transferred between the wheelchair and the left seat 12 in a space sandwiched between the outer surface in the vehicle width direction of the left seat 12 and the inner surface in the vehicle width direction of the door 13 14 is arranged.

図２、図３および図７に示すように、乗員移乗装置１４は、車体のフロアパネル２１にブラケット２２，２２を介して支持された前後一対の四節リンク機構２３，２３を備えており、前側の四節リンク機構２３および後側の四節リンク機構２３の構造は実質的に同一である。各々の四節リンク機構２３は、下端がブラケット２２に固定された上向きに起立する第１縦リンク２４と、第１縦リンク２４の下部にピン２５を介して長手方向一端を枢支されて、所定の上昇位置とそこから車幅方向外方に倒伏した下降位置との間を揺動可能な第１横リンク２６と、第１縦リンク２４の上部にピン２７を介して長手方向一端を枢支されて、所定の上昇位置とそこから車幅方向外方に倒伏した下降位置との間を揺動可能な第２横リンク２８と、第１横リンク２６および第２横リンク２８の各長手方向他端に下端および上端をそれぞれピン２９，３０を介して枢支された第２縦リンク３１とで構成される。ピン３０は長尺であり、一対の四節リンク機構２３，２３に共用される。一対の四節リンク機構２３の２本の第２横リンク２８，２８の中間部は前後方向に延びる連結部材３２で一体に連結される。 As shown in FIGS. 2, 3 and 7, the occupant transfer device 14 includes a pair of front and rear four-bar linkage mechanisms 23, 23 supported on the floor panel 21 of the vehicle body via brackets 22, 22. The structures of the front four-link mechanism 23 and the rear four-link mechanism 23 are substantially the same. Each four-bar linkage mechanism 23 has a first vertical link 24 whose lower end is fixed to the bracket 22 and stands upward, and one end in the longitudinal direction is pivotally supported by a lower portion of the first vertical link 24 via a pin 25. A first horizontal link 26 that can swing between a predetermined ascending position and a descending position that has fallen outward in the vehicle width direction, and one end in the longitudinal direction pivoted via a pin 27 above the first vertical link 24. The second lateral link 28 supported and swingable between a predetermined ascending position and a descending position where the vehicle descends outward in the vehicle width direction, and the longitudinal lengths of the first lateral link 26 and the second lateral link 28 The lower end and the upper end of the other end in the direction are constituted by a second vertical link 31 pivotally supported via pins 29 and 30, respectively. The pin 30 is long and is shared by the pair of four-bar linkage mechanisms 23 and 23. The intermediate portions of the two second horizontal links 28, 28 of the pair of four-bar linkage mechanisms 23 are integrally connected by a connecting member 32 extending in the front-rear direction.

各四節リンク機構２３は、第１横リンク２６および第２横リンク２８が第１縦リンク２４との間に設けたピン２５，２７を支点として上下方向に揺動すると、第２縦リンク３１が第１縦リンク２４と平行な鉛直姿勢を保ったまま円弧状の軌跡で昇降する。第１横リンク２６および第２横リンク２８が倒伏する下降位置では、第２縦リンク３１は最も下降し、かつ車幅方向外側に最も張り出した状態となり、逆に第１横リンク２６および第２横リンク２８が起立する上昇位置では、第２縦リンク３１は最も上昇し、かつ車幅方向内側に最も引き込まれた状態となる。 When the first horizontal link 26 and the second horizontal link 28 swing in the vertical direction using the pins 25 and 27 provided between the first horizontal link 26 and the second horizontal link 24 as fulcrums, Is moved up and down along an arcuate locus while maintaining a vertical posture parallel to the first vertical link 24. At the lowered position where the first horizontal link 26 and the second horizontal link 28 fall, the second vertical link 31 descends most and protrudes most outward in the vehicle width direction. At the raised position where the horizontal link 28 stands up, the second vertical link 31 rises most and is most retracted inward in the vehicle width direction.

移乗ボード３４の車幅方向内端の下面に突設された前後一対のブラケット３６，３６が、前記長尺のピン３０により回動可能に枢支される。また移乗ボード３４の車幅方向中間部の下面に突設された前後一対のブラケット３７，３７に、ガイドリンク３８，３８の一端がピン３５，３５を介して枢支され、ガイドリンク３８，３８の他端に形成した長孔３８ａ，３８ａが第２縦リンク３１，３１の中間部に設けたピン３９，３９に摺動可能に係合する。従って、移乗ボード３４をピン３０まわりに揺動させることで、水平方向に張り出す使用状態と上下方向に起立する格納状態とを選択することができる。移乗ボード３４に被介助者が着座したとき、その体重は長孔３８ａ，３８ａの端部にピン３９，３９が当接することで四節リンク機構２３，２３により支持される。 A pair of front and rear brackets 36, 36 projecting from the lower surface of the inner end in the vehicle width direction of the transfer board 34 are pivotally supported by the long pins 30. One end of the guide link 38, 38 is pivotally supported by a pair of front and rear brackets 37, 37 projecting from the lower surface of the intermediate portion in the vehicle width direction of the transfer board 34 via the pins 35, 35. Long holes 38a, 38a formed at the other end of the second slidably engage with pins 39, 39 provided in the middle part of the second vertical links 31, 31 in a slidable manner. Therefore, by swinging the transfer board 34 around the pin 30, it is possible to select a use state in which the transfer board 34 extends in the horizontal direction and a storage state in which the transfer board 34 stands up and down. When the person being assisted sits on the transfer board 34, the weight of the person being supported is supported by the four-bar linkage mechanism 23, 23 by the pins 39, 39 coming into contact with the ends of the long holes 38a, 38a.

連結部材３２の前後方向中間部に設けたブラケット４０にピン４１を介して第１駆動リンク４２の車幅方向外端が枢支され、フロアパネル２１に設けたブラケット４３にピン４４を介して第２駆動リンク４５の車幅方向外端が枢支される。シート１２の下面にガスダンパー４６が車幅方向に配置されており、ガスダンパー４６のロッド部４６ａの先端に第１駆動リンク４２および第２駆動リンク４５の車幅方向内端が共通のピン４７を介して枢支される。ガスダンパー４６のロッド部４６ａは車幅方向外側に突出する方向に付勢されており、その荷重が第１駆動リンク４２および第２駆動リンク４５を介して連結部材３２を上方に押圧することで、四節リンク機構２３，２３は起立方向に付勢される。 The outer end in the vehicle width direction of the first drive link 42 is pivotally supported by a bracket 40 provided in the middle part of the connecting member 32 in the front-rear direction, and the bracket 43 provided on the floor panel 21 is supported by a pin 44 via a pin 44. The outer end in the vehicle width direction of the two drive links 45 is pivotally supported. A gas damper 46 is disposed on the lower surface of the seat 12 in the vehicle width direction, and a pin 47 having a common inner end in the vehicle width direction of the first drive link 42 and the second drive link 45 at the tip of the rod portion 46a of the gas damper 46 is provided. It is pivoted through. The rod portion 46a of the gas damper 46 is biased in a direction protruding outward in the vehicle width direction, and the load presses the connecting member 32 upward via the first drive link 42 and the second drive link 45. The four-bar linkage mechanism 23, 23 is urged in the standing direction.

尚、乗員移乗装置１４か下降位置および上昇位置にあるとき、図示せぬロック機構で四節リンク機構２３，２３の変形を阻止することで、移乗ボード３４を昇降不能にロックすることができる。 When the occupant transfer device 14 is in the lowered position and the raised position, the transfer board 34 can be locked so as not to be lifted by preventing the four-bar linkage mechanisms 23, 23 from being deformed by a lock mechanism (not shown).

次に、上記構成を備えた本発明の実施の形態の作用を説明する。 Next, the operation of the embodiment of the present invention having the above configuration will be described.

車椅子に乗った被介助者を車両１１のシート１２に移乗させるには、図４の状態から、先ず介助者がドア１３を開き、上昇位置にロックされた乗員移乗装置１４に設けた移乗ボード３４を起立する収納位置から車幅方向外側に水平方向に張り出す使用位置へと倒伏させる（図３参照）。続いて、介助者が乗員移乗装置１４のロックを解除して移乗ボード３４を押し下げると、ガスダンパー４６を圧縮しながら四節リンク機構２３，２３が変形することで、移乗ボード３４が車幅方向外側に移動しながら下降する。そして移乗ボード３４が図５および図８に示す中間位置を経て図６および図９に示す下降位置に達したときに、その下降位置で乗員移乗装置１４をロックする。 In order to transfer the person on the wheelchair to the seat 12 of the vehicle 11, from the state of FIG. 4, the assistant first opens the door 13, and the transfer board 34 provided on the occupant transfer device 14 locked in the raised position. Lie down from the stowed storage position to a use position that extends horizontally outward in the vehicle width direction (see FIG. 3). Subsequently, when the assistant releases the lock of the occupant transfer device 14 and pushes down the transfer board 34, the four-bar linkage mechanisms 23, 23 are deformed while compressing the gas damper 46, so that the transfer board 34 is moved in the vehicle width direction. Lower while moving outward. When the transfer board 34 reaches the lowered position shown in FIGS. 6 and 9 through the intermediate position shown in FIGS. 5 and 8, the occupant transfer device 14 is locked at the lowered position.

続いて、図１０（Ａ）に示すように、車椅子の被介助者を移乗ボード３４に移動させた後に乗員移乗装置１４のロックを解除する。このとき、ガスダンパー４６の弾発力は被介助者の体重よりも僅かに小さく設定されているため、移乗ボード３４は四節リンク機構２３，２３を変形させながら図５および図８に示す中間位置まで車幅方向内側に移動しながら上昇する。この中間位置から介助者が移乗ボード３４を僅かな力で上向きに持ち上げることで、移乗ボード３４は車幅方向内側に移動しながら更に上昇し、図３および図７に示す上昇位置に達したときに、乗員移乗装置１４を再度ロックする。この状態で、図１０（Ｂ）に示すように、被介助者は移乗ボード３４から車室内に移動することでシート１２に移乗することができる。このようにして被介助者がシート１２に移乗すると、図４に示すように、移乗ボード３４を使用位置から収納位置へと上方に折り畳むことで、ドア１３を移乗ボード３４と干渉することなく閉じることができる。 Subsequently, as shown in FIG. 10 (A), the occupant transfer device 14 is unlocked after moving the person being assisted in the wheelchair to the transfer board 34. At this time, since the elastic force of the gas damper 46 is set to be slightly smaller than the weight of the person being assisted, the transfer board 34 is deformed in the four-bar linkage mechanism 23, 23 while the intermediate position shown in FIGS. Ascend while moving inward in the vehicle width direction to the position. When the assistant lifts the transfer board 34 upward with a slight force from this intermediate position, the transfer board 34 further moves upward in the vehicle width direction and reaches the raised position shown in FIGS. 3 and 7. Then, the occupant transfer device 14 is locked again. In this state, as shown in FIG. 10B, the person being assisted can move to the seat 12 by moving from the transfer board 34 into the vehicle compartment. When the person being assisted transfers to the seat 12 in this manner, the door 13 is closed without interfering with the transfer board 34 by folding the transfer board 34 upward from the use position to the storage position as shown in FIG. be able to.

被介助者をシート１２から車椅子に移乗させるのには、上述した手順と逆に、ドア１３を開いて移乗ボード３４を使用位置へと倒してから、被介助者をシート１２から移乗ボード３４に移動させる。続いて、乗員移乗装置１４のロックを解除すると被介助者の体重でガスダンパー４６が圧縮されることで、四節リンク機構２３，２３を変形させながら移乗ボード３４が車幅方向外側に移動しながら中間位置まで下降するので、介助者は移乗ボード３４を下降位置まで更に押し下げた後に乗員移乗装置１４をロックし、被介助者を移乗ボード３４から車椅子に移乗させれば良い。その後は、移乗ボード３４を下降位置から上昇位置に上昇させて起立姿勢にすれば、ドア１３を閉じることができる。 In order to transfer the person being assisted from the seat 12 to the wheelchair, the door 13 is opened and the transfer board 34 is brought down to the use position, and then the person being assisted is transferred from the seat 12 to the transfer board 34. Move. Subsequently, when the occupant transfer device 14 is unlocked, the gas damper 46 is compressed by the weight of the person being assisted, so that the transfer board 34 moves outward in the vehicle width direction while deforming the four-bar linkage mechanisms 23 and 23. However, since the assistant is lowered to the intermediate position, the assistant may further push down the transfer board 34 to the lowered position, lock the occupant transfer device 14, and transfer the person being assisted from the transfer board 34 to the wheelchair. Thereafter, the door 13 can be closed by raising the transfer board 34 from the lowered position to the raised position to be in a standing posture.

以上のように、四節リンク機構２３，２３をガスダンパー４６の弾発力で上方に付勢するので、被介助者の体重とガスダンパー４６の弾発力とを釣り合わせることで、ごく僅かな力で被介助者を昇降させることができる。しかも電動モータのような特別の駆動源を必要としないので低コストで実現可能であるだけでなく、コンパクトな構造であるので車室空間を圧迫したり健常者の乗降に対して邪魔になったりすることがない。 As described above, since the four-bar linkage mechanism 23, 23 is biased upward by the elastic force of the gas damper 46, the balance between the weight of the person being assisted and the elastic force of the gas damper 46 is negligible. The person being assisted can be raised and lowered with great force. In addition, it does not require a special drive source such as an electric motor, so it can be realized at low cost, and it has a compact structure, so it can compress the passenger compartment space and interfere with getting on and off of a healthy person. There is nothing to do.

しかも移乗ボード３４を四節リンク機構２３，２３を介して昇降可能に支持したので、移乗ボード３４が下降すると車体側面から斜めに遠ざかって車椅子との間の移乗が容易になり、移乗ボード３４が上昇すると車体側面に斜めに近づいてシート１２との間の移乗が容易になる。 Moreover, since the transfer board 34 is supported by the four-bar linkages 23 and 23 so as to be lifted and lowered, when the transfer board 34 is lowered, the transfer board 34 is inclined away from the side surface of the vehicle body to facilitate transfer to and from the wheelchair. When it rises, it moves closer to the side of the vehicle body and becomes easy to transfer to and from the seat 12.

またガスダンパー４６は一対の四節リンク機構２３，２３の第２横リンク２８，２８を連結する連結部材３２を押圧することで移乗ボード３４を上方に付勢するので、ガスダンパー４６の付勢力を一対の四節リンク機構２３，２３に均等に配分して移乗ボード３４を安定した姿勢で昇降させることができる。 Further, since the gas damper 46 biases the transfer board 34 upward by pressing the connecting member 32 that couples the second lateral links 28, 28 of the pair of four-bar linkage mechanisms 23, 23, the biasing force of the gas damper 46 Can be evenly distributed to the pair of four-bar linkage mechanisms 23, 23 to move the transfer board 34 up and down in a stable posture.

またガスダンパー４６をシ−ト１２の下方に配置したので、ガスダンパー４６が被介助者の移乗の邪魔になったり、ガスダンパー４６が車室空間を狭めたりするのを回避することができる。 In addition, since the gas damper 46 is disposed below the sheet 12, it is possible to avoid the gas damper 46 from interfering with the person being assisted and the gas damper 46 from narrowing the passenger compartment space.

また乗員移乗装置１４に臨むドア１３はスライドドアであるので、シート１２との間に乗員移乗装置１４を配置するスペースを容易に確保することができるだけでなく、ドア開口を広く確保して被介助者の乗降を一層容易に行わせることができる。 Further, since the door 13 facing the occupant transfer device 14 is a slide door, not only can a space for the occupant transfer device 14 disposed between the seat 12 and the seat 12 to be easily secured, but also a wide opening of the door is secured. The person can get on and off more easily.

以上、本発明の実施の形態を説明したが、本発明はその要旨を逸脱しない範囲で種々の設計変更を行うことが可能である。 The embodiments of the present invention have been described above, but various design changes can be made without departing from the scope of the present invention.

例えば、本発明の付勢手段は実施の形態のガスダンパー４６に限定されず、筒内にコイルスプリングを収納したスプリングダンパー等の弾発部材であっても良く、また電動モータの駆動源を備えるものであっても良い。 For example, the biasing means of the present invention is not limited to the gas damper 46 of the embodiment, and may be a resilient member such as a spring damper in which a coil spring is housed in a cylinder, and includes a drive source of an electric motor. It may be a thing.

また実施の形態では乗員移乗装置１４を車体左側のシート１２に設けているが、それを車体右側のシートに設けても良い。 In the embodiment, the occupant transfer device 14 is provided on the seat 12 on the left side of the vehicle body, but it may be provided on the seat on the right side of the vehicle body.

また実施の形態では２個の四節リンク機構２３，２３を用いているが、四節リンク機構の数は複数個であれば良い。 In the embodiment, two four-bar linkage mechanisms 23, 23 are used. However, the number of four-bar linkages may be plural.

また実施の形態では連結部材３２が一対の第２横リンク２８，２８間を連結しているが、連結部材３２は一対の四節リンク機構２３，２３の他の任意の部材間を連結するものでも良い。 In the embodiment, the connecting member 32 connects the pair of second horizontal links 28, 28, but the connecting member 32 connects the other arbitrary members of the pair of four-bar linkage mechanisms 23, 23. But it ’s okay.
