支持体１１の第１部位１１１は、前後方向に延びる一対の支持部１１６を有している。各支持部１１６の内側には、断面Ｕ字状に形成され水平方向に開口するレール１１７が形成されている。すなわち、各支持部１１６のレール１１７の開口が互いに向き合うように配置されている。各レール１１７の内部には、後述する移動制御部材１３の棒状部材１３１が進退可能に挿入される。また、このレール１１７の上面には後述する椅子１２の下端部に設けられた第２ローラ１２０が載り、第２ローラ１２０がレール１１７の上面に沿って進退するように構成されている。 The first portion 111 of the support 11 has a pair of support portions 116 extending in the front-rear direction. Inside each support portion 116, a rail 117 having a U-shaped cross section and opening in the horizontal direction is formed. That is, the openings of the rails 117 of the support portions 116 are arranged so as to face each other. Inside each rail 117, a rod-shaped member 131 of a movement control member 13, which will be described later, is inserted so as to be able to advance and retreat. Further, a second roller 120 provided at the lower end of the chair 12, which will be described later, is mounted on the upper surface of the rail 117, and the second roller 120 is configured to advance and retreat along the upper surface of the rail 117.

次に、椅子１２について説明する。椅子１２は、前後方向に延びる座部１２２と、この座部１２２の後端部に連結され、略上方に延びる背もたれ部１２１とを備えており、側面視Ｌ字状に形成されている。また、背もたれ部１２１は、座部１２２と連結される背もたれ部本体１２３と、その上端に連結された延在部１２４とを備えている。延在部１２４の両側は折り曲げられており、その両側の内側には上述した第１ローラ１２５が回転可能に取り付けられている。そして、各第１ローラ１２５は、上述したように、支持体１１の第２レール１１５に嵌まっている。 Next, the chair 12 will be described. The chair 12 includes a seat portion 122 extending in the front-rear direction and a backrest portion 121 connected to the rear end portion of the seat portion 122 and extending substantially upward, and is formed in an L-shape in a side view. Further, the backrest portion 121 includes a backrest portion main body 123 connected to the seat portion 122, and an extending portion 124 connected to the upper end thereof. Both sides of the extending portion 124 are bent, and the above-mentioned first roller 125 is rotatably attached to the inside of both sides thereof. Then, as described above, each first roller 125 is fitted to the second rail 115 of the support 11.

座部１２２は、平面視Ｕ状に形成された板状の座部本体１２６と、この座部本体１２６の両側に連結された板状の側面部１２７と、を有している。各側面部１２７には、背もたれ部１２１側において下方に突出する第１係合部１２８と、先端部において下方に突出する第２係合部１２９とが形成されている。第２係合部１２９の突出長さは、第１係合部１２８よりやや長くなっている。また、各側面部１２７において、第１係合部１２８と第２係合部１２９との間には、水平方向に突出する第２ローラ１２０が回転可能に取り付けられている。 The seat portion 122 has a plate-shaped seat portion main body 126 formed in a U-shape in a plan view, and plate-shaped side surface portions 127 connected to both sides of the seat portion main body 126. Each side surface portion 127 is formed with a first engaging portion 128 projecting downward on the backrest portion 121 side and a second engaging portion 129 projecting downward on the tip portion. The protruding length of the second engaging portion 129 is slightly longer than that of the first engaging portion 128. Further, in each side surface portion 127, a second roller 120 projecting in the horizontal direction is rotatably attached between the first engaging portion 128 and the second engaging portion 129.

次に、移動制御部材１３について説明する。移動制御部材１３は、一対の棒状部材（棒状部）１３１と、これら棒状部材１３１を互いに連結する連結部１３２と、を備えている。各棒状部材１３１は、支持体１１の各第２レール１１５に進退可能に挿入されている。また、各棒状部材１３１には抜け止め部材（図示省略）が取り付けられており、これによって、各棒状部材１３１が第２レール１１５から抜け出さないようになっている。すなわち、各棒状部材１３１は、第２レール１１５から所定の長さだけ前進するように前方への移動が規制されている。ここで、各棒状部材１３１が第２レール１１５に対して最も後退した位置を第１位置と称し、各棒状部材１３１が第２レール１１５に対して最も前進した位置を第２位置と称することとする。 Next, the movement control member 13 will be described. The movement control member 13 includes a pair of rod-shaped members (rod-shaped portions) 131 and a connecting portion 132 that connects the rod-shaped members 131 to each other. Each rod-shaped member 131 is inserted into each second rail 115 of the support 11 so as to be able to advance and retreat. Further, a retaining member (not shown) is attached to each rod-shaped member 131 so that each rod-shaped member 131 does not come out of the second rail 115. That is, each rod-shaped member 131 is restricted from moving forward so as to advance by a predetermined length from the second rail 115. Here, the position where each rod-shaped member 131 is most retracted with respect to the second rail 115 is referred to as a first position, and the position where each rod-shaped member 131 is most advanced with respect to the second rail 115 is referred to as a second position. do.

連結部１３２は、平面視Ｕ字状の板状に形成されており、その両側の後端部が棒状部材１３１にそれぞれ固定されている。一方、連結部１３２の両側の前端部は棒状部材１３１には連結されておらず、隙間１３３がそれぞれ形成されている。そして、各隙間１３３には、上述した座部１２２の第２係合部１２９が前側から進入し、連結部１３２に係合するようになっている。また、連結部１３２の後端には、座部１２２の第１係合部１２８が係合するようになっている。 The connecting portion 132 is formed in a U-shaped plate shape in a plan view, and the rear end portions on both sides thereof are fixed to the rod-shaped member 131, respectively. On the other hand, the front ends on both sides of the connecting portion 132 are not connected to the rod-shaped member 131, and gaps 133 are formed respectively. Then, the second engaging portion 129 of the seat portion 122 described above enters each gap 133 from the front side and engages with the connecting portion 132. Further, the first engaging portion 128 of the seat portion 122 is engaged with the rear end of the connecting portion 132.

図５及び図６に示すように、棒状部材１３１は、円筒状に形成されており、その内部空間は前方領域１３４と後方領域１３５に区分けされている。前方領域１３４には、円筒状の規制部材１３６が固定されており、この規制部材１３６によって前方領域１３４の内径が、後方領域１３５の内径よりも小さくなっている。また、規制部材１３６の内壁面の両側には、水平方向に窪む一対の溝１３７が形成されており、規制部材１３６の軸方向に延びている。この規制部材１３６には、後述するフットサポート１４の軸部材が挿入される。 As shown in FIGS. 5 and 6, the rod-shaped member 131 is formed in a cylindrical shape, and its internal space is divided into a front region 134 and a rear region 135. A cylindrical restricting member 136 is fixed to the front region 134, and the inner diameter of the front region 134 is made smaller than the inner diameter of the rear region 135 by the restricting member 136. Further, a pair of grooves 137 recessed in the horizontal direction are formed on both sides of the inner wall surface of the regulating member 136, and extend in the axial direction of the regulating member 136. A shaft member of the foot support 14, which will be described later, is inserted into the regulating member 136.

次に、フットサポートについて説明する。図４に示すように、各フットサポート１４は、左右対称の形状となっているため、ここでは、向かって右側のフットサポート１４について説明する。各フットサポート１４は、棒状の軸部材（進退部材）１４１と、この軸部材１４１の先端に回転可能に固定された載置部１４２と、を備えている。軸部材１４１の後端部の両側には、水平方向に突出する一対の突部１４３が形成されている。一方、軸部材１４１の先端部には、突部１４３と平行に延びるように載置部１４２が連結されている。 Next, the foot support will be described. As shown in FIG. 4, since each foot support 14 has a symmetrical shape, the foot support 14 on the right side thereof will be described here. Each foot support 14 includes a rod-shaped shaft member (advancing / retreating member) 141, and a mounting portion 142 rotatably fixed to the tip of the shaft member 141. A pair of protrusions 143 protruding in the horizontal direction are formed on both sides of the rear end portion of the shaft member 141. On the other hand, a mounting portion 142 is connected to the tip portion of the shaft member 141 so as to extend in parallel with the protrusion 143.

図５に示すように、軸部材１４１は、移動制御部材１３の棒状部材１３１に進退可能に挿入される。軸部材１４１の外径は棒状部材１３１の内部の規制部材１３６の内径と概ね同じとなっている。そのため、軸部材１４１は、規制部材１３６に沿って進退するようになっている。このとき、軸部材１４１の各突部１４３は、規制部材１３６の各溝１３７に係合し、これによって、軸部材１４１の軸周りの角度が位置決めされる。すなわち、軸部材１４１の突部１４３が溝に１３７係合しているときには、載置部１４２が水平方向に延びた状態が維持されたままで、軸部材１４１が進退するようになっている。 As shown in FIG. 5, the shaft member 141 is inserted into the rod-shaped member 131 of the movement control member 13 so as to be able to advance and retreat. The outer diameter of the shaft member 141 is substantially the same as the inner diameter of the regulating member 136 inside the rod-shaped member 131. Therefore, the shaft member 141 moves forward and backward along the regulation member 136. At this time, each protrusion 143 of the shaft member 141 engages with each groove 137 of the regulating member 136, whereby the angle around the axis of the shaft member 141 is positioned. That is, when the protrusion 143 of the shaft member 141 is engaged with the groove 137, the shaft member 141 moves back and forth while the mounting portion 142 is maintained in a horizontally extended state.

一方、軸部材１４１が棒状部材１３１に対して押し込まれ、突部１４３が規制部材１３６から離脱し、後方領域１３５に入ったとときには、軸部材１４１は、棒状部材１３１に対して軸周りに回転可能となる。したがって、図６に示すように、載置部１４２を下方に向けることができる。なお、軸部材１４１には抜け止め部材（図示省略）が取り付けられており、これによって、各軸部材１４１が棒状部材１３１から抜け出さないようになっている。すなわち、各軸部材１４１は、棒状部材１３１から所定の長さだけ前進するように前方への移動が規制されている。 On the other hand, when the shaft member 141 is pushed against the rod-shaped member 131, the protrusion 143 separates from the regulating member 136 and enters the rear region 135, the shaft member 141 can rotate about the axis with respect to the rod-shaped member 131. Will be. Therefore, as shown in FIG. 6, the mounting portion 142 can be directed downward. A retaining member (not shown) is attached to the shaft member 141 so that each shaft member 141 does not come out of the rod-shaped member 131. That is, each shaft member 141 is restricted from moving forward so as to advance by a predetermined length from the rod-shaped member 131.

載置部１４２は、被介護者の足が載せられるように板状に形成されており、軸部材１４１に対し、水平方向に延びる軸周りに回転可能になっている。したがって、軸部材１４１に対して載置部１４２を回転させることで、被介護者の足に向きに合わせて、載置部１４２を所望の角度に傾斜させることができる。 The mounting portion 142 is formed in a plate shape so that the foot of the care recipient can be placed on the mounting portion 142, and is rotatable around an axis extending in the horizontal direction with respect to the shaft member 141. Therefore, by rotating the mounting portion 142 with respect to the shaft member 141, the mounting portion 142 can be tilted at a desired angle according to the direction of the care recipient's foot.

以上のように構成された各部材によって、椅子ユニット１は、以下のように動作する。この点について、図７～図１１を参照しつつ説明を行う。図７～図１１は、椅子ユニットの動作を示す側面図である。特に、本実施形態に係る椅子ユニット１は、両係合部１２８，１２９及び移動制御部材１３により、以下のような４つの動作の制御を行うことができる。 The chair unit 1 operates as follows by each member configured as described above. This point will be described with reference to FIGS. 7 to 11. 7 to 11 are side views showing the operation of the chair unit. In particular, the chair unit 1 according to the present embodiment can control the following four operations by the both engaging portions 128 and 129 and the movement control member 13.

（Ａ）第１動作制御
まず、図７（ａ）は、初期状態を示す側面である。初期状態においては、フットサポート１４は後退しており、突部１４３が後方領域１３５内にある。そして、軸部材１４１は、載置部１４２が下方に延びるように回転している。以下、このフットサポート１４の状態を初期状態と称することとする。このとき、両載置部１４２は、概ね支持体１１の第１部位１１１及び座部１２２の下方に位置している。 (A) First operation control First, FIG. 7A is an aspect showing an initial state. In the initial state, the foot support 14 is retracted and the protrusion 143 is in the rear region 135. Then, the shaft member 141 is rotated so that the mounting portion 142 extends downward. Hereinafter, the state of the foot support 14 will be referred to as an initial state. At this time, both mounting portions 142 are generally located below the first portion 111 and the seat portion 122 of the support 11.

椅子１２が初期状態にあるときには、第１係合部１２８は、下方に突出しているものの、支持体１１の第１部位１１１からは下方には突出しないようになっており、椅子１２が前進しても第１部位１１１からは下方に突出しないようになっている。また、椅子１２が初期状態にあるときには、第１係合部１２８は、移動制御部材１３の連結部１３２のやや後方に位置している。 When the chair 12 is in the initial state, the first engaging portion 128 projects downward, but does not protrude downward from the first portion 111 of the support 11, and the chair 12 advances. However, it does not protrude downward from the first portion 111. Further, when the chair 12 is in the initial state, the first engaging portion 128 is located slightly behind the connecting portion 132 of the movement control member 13.

上述したように、椅子１２の背もたれ部１２１の第１ローラ１２５が支持体１１の第２レール１１５に対して上下動可能であり、第２ローラ１２０が支持体１１のレール１１７の上面に沿って進退可能であるため、椅子１２は、初期状態から、図７（ｂ）の状態を経て図７（ｃ）の状態になるまで傾斜するようになっている。すなわち、椅子１２は座部１２２の先端が状態を向くように傾斜するようになっている。以下、図７（ｃ）の状態を、チルト状態と称することとする。 As described above, the first roller 125 of the backrest portion 121 of the chair 12 can move up and down with respect to the second rail 115 of the support 11, and the second roller 120 is along the upper surface of the rail 117 of the support 11. Since the chair 12 can be moved forward and backward, the chair 12 is tilted from the initial state to the state shown in FIG. 7 (b) and then to the state shown in FIG. 7 (c). That is, the chair 12 is tilted so that the tip of the seat portion 122 faces the state. Hereinafter, the state of FIG. 7 (c) will be referred to as a tilt state.

図７（ｂ）の状態では、第１係合部１２８が移動制御部材１３の連結部１３２に接しており、ここから図７（ｃ）のチルト状態まで椅子１２が傾くと、第１係合部１２８が移動制御部材１３を前方に押しやるようになっている。したがって、椅子１２がチルト状態になったときには、図７（ｃ）に示すように、移動制御部材１３はフットサポート１４とともに、初期状態から前方に移動する。 In the state of FIG. 7 (b), the first engaging portion 128 is in contact with the connecting portion 132 of the movement control member 13, and when the chair 12 is tilted from here to the tilted state of FIG. 7 (c), the first engaging portion is engaged. The unit 128 pushes the movement control member 13 forward. Therefore, when the chair 12 is in the tilted state, as shown in FIG. 7C, the movement control member 13 moves forward from the initial state together with the foot support 14.

そして、フットサポート１４は、初期状態から軸部材１４１を回転させ、突部１４３を規制部材１３６の溝１３７に係合させた状態で、図８に示すように、前方へ移動できる。以下、このフットサポート１４の状態を前進状態と称することとする。 Then, the foot support 14 can move forward as shown in FIG. 8 in a state where the shaft member 141 is rotated from the initial state and the protrusion 143 is engaged with the groove 137 of the regulating member 136. Hereinafter, the state of the foot support 14 will be referred to as a forward state.

（Ｂ）第２動作制御
図７（ａ）に示すように、椅子１２が初期状態にあるとき、第２係合部１２９も、下方に突出しているものの、支持体１１の第１部位１１１からは下方には突出しないようになっており、椅子１２が前進しても第１部位１１１からは突出しないようになっている。また、第２係合部１２９は、移動制御部材１３よりもやや前方に位置しているが、隙間１３３には係合していない。したがって、椅子１２が初期状態にあるときには、移動制御部材１３は、第２係合部１２９が隙間１３３に係合するまで前進が可能となっているが、第２係合部１２９が隙間１３３に係合すると、それ以上の前進ができないようになっている。図８は、移動制御部材１３の前進が第２係合部１２９によって規制された状態を示している。但し、同図に示すように、フットサポート１４は初期状態から全身状態へ移動可能である。 (B) Second operation control As shown in FIG. 7A, when the chair 12 is in the initial state, the second engaging portion 129 also protrudes downward, but from the first portion 111 of the support 11. Is designed not to protrude downward, and does not protrude from the first portion 111 even if the chair 12 moves forward. Further, the second engaging portion 129 is located slightly ahead of the movement control member 13, but is not engaged with the gap 133. Therefore, when the chair 12 is in the initial state, the movement control member 13 can move forward until the second engaging portion 129 engages with the gap 133, but the second engaging portion 129 is in the gap 133. Once engaged, no further advance is possible. FIG. 8 shows a state in which the advance of the movement control member 13 is restricted by the second engaging portion 129. However, as shown in the figure, the foot support 14 can move from the initial state to the general state.

そして、初期状態からチルト状態に向かって椅子１２が傾くと、椅子１２の座部１２２の前端が上方に傾くため、これに伴って、第２係合部１２９も上方に移動する。これにより、図７（ｃ）に示すように、移動制御部材１３が前方に移動しても、第２係合部１２９とは係合しないようになっている。これにより、図９に示すように、椅子１２がチルト状態にあるときには、移動制御部材１３は、第１位置から第２位置まで前進できるようになっている。同図では、フットサポート１４も前進状態まで前進させている。 Then, when the chair 12 is tilted from the initial state toward the tilted state, the front end of the seat portion 122 of the chair 12 is tilted upward, and the second engaging portion 129 also moves upward accordingly. As a result, as shown in FIG. 7C, even if the movement control member 13 moves forward, it does not engage with the second engaging portion 129. As a result, as shown in FIG. 9, when the chair 12 is in the tilted state, the movement control member 13 can move forward from the first position to the second position. In the figure, the foot support 14 is also advanced to the advanced state.

（Ｃ）第３動作制御
図１０（ａ）に示すように、椅子１２がチルト状態にあり、移動制御部材１３が第２位置にあるときに、図１０（ｂ）に示すように、椅子１２を初期状態に戻そうとすると、第２係合部１２９が移動制御部材１３の連結部１３２の上面に接するように、それぞれの位置が調整されている。これにより、第２係合部１２９は下方へ移動できないため、椅子１２も初期状態へ移動できないようになっている。このように、本実施形態においては、椅子１２がチルト状態にあり、移動制御部材１３が第２位置にあるときには、移動制御部材１３を第１状態に戻さなければ、椅子１２をチルト状態から初期状態に戻せないようになっている。すなわち、本実施形態においては、移動制御部材１３を第２状態から後方へ移動させた後に、椅子１２をチルト状態に戻すように構成されており、その反対の動作ができないようになっている。 (C) Third operation control As shown in FIG. 10 (a), when the chair 12 is in the tilted state and the movement control member 13 is in the second position, the chair 12 is shown in FIG. 10 (b). When trying to return to the initial state, the respective positions are adjusted so that the second engaging portion 129 comes into contact with the upper surface of the connecting portion 132 of the movement control member 13. As a result, the second engaging portion 129 cannot move downward, so that the chair 12 cannot move to the initial state either. As described above, in the present embodiment, when the chair 12 is in the tilted state and the movement control member 13 is in the second position, the chair 12 is initially tilted from the tilted state unless the movement control member 13 is returned to the first state. It cannot be returned to the state. That is, in the present embodiment, the chair 12 is configured to return to the tilted state after the movement control member 13 is moved backward from the second state, and the opposite operation cannot be performed.

（Ｄ）第４動作制御
椅子１２をチルト状態から初期状態に戻すには、まず、図１１（ａ）に示すように、移動制御部材１３を、連結部１３２が第１係合部１２８に接するまで後方に移動させる。このときの移動制御部材の位置を第３位置と称することとする。この状態から椅子を初期状態に戻すと、図１１（ｂ）に示すように、第２係合部１２９が移動制御部材１３の隙間１３３に進入し、移動制御部材１３を後方に押しやるようになっている。そして、図１１（ｂ）の状態から、さらに椅子１２を初期状態まで移動させると、図１１（ｃ）に示すように、第２係合部１２９によって移動制御部材１３が第１位置付近まで戻されるようになっている。したがって、本実施形態においては、椅子１２のチルト状態から初期状態までの移動に連動して、移動制御部材１３を第１位置付近、つまり初期の位置付近まで戻すことができる。 (D) Fourth operation control In order to return the chair 12 from the tilted state to the initial state, first, as shown in FIG. 11A, the movement control member 13 is brought into contact with the first engaging portion 128 by the connecting portion 132. Move backwards to. The position of the movement control member at this time is referred to as a third position. When the chair is returned to the initial state from this state, as shown in FIG. 11B, the second engaging portion 129 enters the gap 133 of the movement control member 13 and pushes the movement control member 13 backward. ing. Then, when the chair 12 is further moved from the state of FIG. 11 (b) to the initial state, the movement control member 13 is returned to the vicinity of the first position by the second engaging portion 129 as shown in FIG. 11 (c). It is designed to be used. Therefore, in the present embodiment, the movement control member 13 can be returned to the vicinity of the first position, that is, to the vicinity of the initial position in conjunction with the movement of the chair 12 from the tilt state to the initial state.

なお、椅子１２の初期状態とチルト状態の間の移動は、種々の駆動方式によって行うことができる。例えば、本体部２に内蔵されたモータ（図示省略）で行うことができる。あるいは、手動によって行うようにしてもよい。 The movement of the chair 12 between the initial state and the tilted state can be performed by various drive methods. For example, it can be performed by a motor (not shown) built in the main body 2. Alternatively, it may be done manually.

＜１－２．本体部＞
次に、本体部２について説明する。図１に示すように、本体部２は、直方体状のケーシング２１と、このケーシング２１に内蔵されているモータ（図示省略）と、を備えている。モータは、上述したようにピニオンを回転させるためのものである。ケーシング２１の前面は、下方にいくにしたがって、前方に向かうように傾斜している。また、ケーシング２１の前面にはガイドローラ（図示省略）が配置されており、このガイドローラが、上述した椅子ユニット１の第１レール１１４に嵌め込まれている。これにより、椅子ユニット１は、ケーシング２１の前側において上下動可能となっている。また、ケーシング２１の前面が上記のように傾斜しているため、椅子ユニット１もこの傾斜に沿って上下動するように構成されている。例えば、椅子ユニット１がケーシング２１に対して下方に移動すると、やや前方に向かうように移動する。 <1-2. Main body>
Next, the main body 2 will be described. As shown in FIG. 1, the main body 2 includes a rectangular parallelepiped casing 21 and a motor (not shown) built in the casing 21. The motor is for rotating the pinion as described above. The front surface of the casing 21 is inclined toward the front as it goes downward. Further, a guide roller (not shown) is arranged on the front surface of the casing 21, and the guide roller is fitted into the first rail 114 of the chair unit 1 described above. As a result, the chair unit 1 can move up and down on the front side of the casing 21. Further, since the front surface of the casing 21 is inclined as described above, the chair unit 1 is also configured to move up and down along this inclination. For example, when the chair unit 1 moves downward with respect to the casing 21, it moves slightly forward.

上述したように、椅子１２の移動は、本体部２に設けられた椅子ユニット１の上下動のためのモータを所定の連結機構によって連結して行うことができる。あるいは、このモータとは別のモータで、椅子１２の移動を行うこともできる。 As described above, the movement of the chair 12 can be performed by connecting the motors for the vertical movement of the chair unit 1 provided in the main body 2 by a predetermined connecting mechanism. Alternatively, the chair 12 can be moved by a motor different from this motor.

なお、後述するように、被介護者の入浴時には、椅子ユニット１と本体部２とが介護用椅子１００から分離し、浴槽８側へ移動する。 As will be described later, when the care recipient takes a bath, the chair unit 1 and the main body 2 are separated from the care chair 100 and move to the bathtub 8 side.

＜１－３．基台＞
次に、基台３について説明する。基台３は、複数の車輪３５１，３５２が設けられた基部３１と、本体部２を支持する第１レール部材３２と、基部３１から上方に延び、第１レール部材３２を支持する支持部３３と、を備えている。 <1-3. Base>
Next, the base 3 will be described. The base 3 includes a base 31 provided with a plurality of wheels 351 and 352, a first rail member 32 that supports the main body 2, and a support portion 33 that extends upward from the base 31 and supports the first rail member 32. And has.

基部３１は、前後方向に延びる一対の棒状の支持部材３１１を備えており、各支持部材３１１の前後の端部の下側に、それぞれ前輪３５１及び後輪３５２が取り付けられている。両支持部材３１１は、左右方向に所定間隔をあけて平行に配置されており、前端部側が第１連結部材３１２により連結されている。一方、両支持部材３１１の前後方向の中間付近は、第２連結部材（図示省略）によって連結されており、この第２連結部材から上述した支持部３３が上方に延び、第１レール部材３２を下側から支持している。 The base 31 includes a pair of rod-shaped support members 311 extending in the front-rear direction, and front wheels 351 and rear wheels 352 are attached to the lower sides of the front and rear ends of each support member 311, respectively. Both support members 311 are arranged in parallel with a predetermined interval in the left-right direction, and the front end portion side is connected by the first connecting member 312. On the other hand, the vicinity of the middle of both support members 311 in the front-rear direction is connected by a second connecting member (not shown), and the above-mentioned support portion 33 extends upward from the second connecting member to provide the first rail member 32. It supports from the bottom.

第１レール部材３２は、左右方向に延びるレールを有しており、このレールにケーシング２１の下端面が移動可能に嵌め込まれている。これにより、ケーシング２１は、第１レール部材３２に沿って左右方向に移動可能となっている。また、ケーシング２１は、第１レール部材３２上にあるとき、その位置をロックできるようになっている。さらに、第１レール部材３２は、後述するように浴槽８の上面に設けられた第２レール部材９とほぼ同じ高さに設置されている。 The first rail member 32 has a rail extending in the left-right direction, and the lower end surface of the casing 21 is movably fitted in the rail. As a result, the casing 21 can move in the left-right direction along the first rail member 32. Further, when the casing 21 is on the first rail member 32, its position can be locked. Further, the first rail member 32 is installed at substantially the same height as the second rail member 9 provided on the upper surface of the bathtub 8 as described later.

＜２．浴槽のレールユニット＞
次に、浴槽のレールユニット２００について説明する。まず、浴槽８について説明する。図２に示すように、浴槽８は、前後方向に平行に延びる第１壁部８１及び第２壁部８２と、左右方向に平行に延びる第３壁部８３及び第４壁部８４と、を有しており、平面視矩形状に形成されている。第１壁部８１は左側（洗場Ｗ側）、第２壁部８２は右側に配置されており、これらは浴槽８の長手方向に延びている。一方、第３壁部８３は前側、第４壁部８４が後側に配置されており、これらは浴槽８の短手方向に延びている。 <2. Bathtub rail unit>
Next, the rail unit 200 of the bathtub will be described. First, the bathtub 8 will be described. As shown in FIG. 2, the bathtub 8 has a first wall portion 81 and a second wall portion 82 extending in parallel in the front-rear direction, and a third wall portion 83 and a fourth wall portion 84 extending in parallel in the left-right direction. It has a rectangular shape in a plan view. The first wall portion 81 is arranged on the left side (washroom W side), and the second wall portion 82 is arranged on the right side, and these extend in the longitudinal direction of the bathtub 8. On the other hand, the third wall portion 83 is arranged on the front side and the fourth wall portion 84 is arranged on the rear side, and these extend in the lateral direction of the bathtub 8.

レールユニット２００は、第１壁部８１の上面に沿って配置される第１固定具７１と、第２壁部８２の上面に沿って配置される第２固定具７２とを備えている。これら固定具７１，７２の下部には各壁部８１，８２を挟む挟持部材（図示省略）が取付けられており、この挟持部材によって各固定具７１，７２を各壁部８１，８２に固定している。 The rail unit 200 includes a first fixture 71 arranged along the upper surface of the first wall portion 81, and a second fixture 72 arranged along the upper surface of the second wall portion 82. A holding member (not shown) that sandwiches the wall portions 81 and 82 is attached to the lower part of the fixtures 71 and 72, and the fixing tools 71 and 72 are fixed to the wall portions 81 and 82 by the holding member. ing.

両固定具７１，７２の上面は平坦に形成されており、これら固定具７１，７２に跨がるように左右方向に延びる第２レール部材９が取付けられている。この第２レール部材の上面にはレールが設けられており、上述した椅子ユニットの本体部２のケーシング２１がスライド可能となっている。 The upper surfaces of both the fixtures 71 and 72 are formed flat, and a second rail member 9 extending in the left-right direction is attached so as to straddle the fixtures 71 and 72. A rail is provided on the upper surface of the second rail member, and the casing 21 of the main body 2 of the chair unit described above can be slidable.

すなわち、第２レール部材９と、介護用椅子１００の第１レール部材３２とは概ね同じ高さに位置しており、第２レール部材９の左端部と、第１レール部材３２の右端部とを接触させたときには、本体部２のケーシング２１が、第１レール部材３２と第２レール部材９とに亘ってスライドできるようになっている。また、第２レール部材９の左端部と、第１レール部材３２の右端部とは、ロック可能となっている。さらに、第２レール部材９に受入れられたケーシング２１は、第２レール部材９上で動かないようにロックできるようになっている。 That is, the second rail member 9 and the first rail member 32 of the nursing chair 100 are located at substantially the same height, and the left end portion of the second rail member 9 and the right end portion of the first rail member 32. The casing 21 of the main body 2 can slide over the first rail member 32 and the second rail member 9 when they are brought into contact with each other. Further, the left end portion of the second rail member 9 and the right end portion of the first rail member 32 can be locked. Further, the casing 21 received by the second rail member 9 can be locked so as not to move on the second rail member 9.

＜３．入浴介護システムの使用方法＞
次に、上記のように構成された入浴介護システムの使用方法について、図１２～図１５も参照しつつ説明する。ここでは、洗場Ｗに配置されている介護用椅子１００の椅子１２を浴槽８内に移動させ、椅子１２に座る被介護者を浴槽８に浸からせる動作について説明する。 <3. How to use the bathing care system ＞
Next, a method of using the bathing care system configured as described above will be described with reference to FIGS. 12 to 15. Here, an operation of moving the chair 12 of the nursing chair 100 arranged in the washroom W into the bathtub 8 and immersing the care recipient sitting in the chair 12 in the bathtub 8 will be described.

まず、図１に示すように、本体部２に対し椅子ユニット１を下降させ、被介護者を椅子１２に座らせる。次に、図１２に示すように、椅子１２を初期状態からチルト状態に移動させた後、移動制御部材１３及びフットサポート１４を前方に移動させる。続いて、被介護者の足を載置部１４２に載せる。この状態で、図１３に示すように、椅子ユニット１を第１壁部８１よりも高い位置まで上昇させる。また、この前後に、第１レール部材３２の右端部と第２レール部材９の左端部とを連結しておく。 First, as shown in FIG. 1, the chair unit 1 is lowered with respect to the main body 2, and the care recipient is made to sit on the chair 12. Next, as shown in FIG. 12, after moving the chair 12 from the initial state to the tilted state, the movement control member 13 and the foot support 14 are moved forward. Subsequently, the foot of the care recipient is placed on the mounting portion 142. In this state, as shown in FIG. 13, the chair unit 1 is raised to a position higher than the first wall portion 81. Further, before and after this, the right end portion of the first rail member 32 and the left end portion of the second rail member 9 are connected.

次に、図１４に示すように、本体部２を第１レール部材３２から第２レール部材９へ向けてスライドさせる。こうして、本体部２とともに椅子ユニット１が浴槽８の上方に位置すると、本体部２がスライドしないように、その位置にロックする。 Next, as shown in FIG. 14, the main body portion 2 is slid from the first rail member 32 toward the second rail member 9. In this way, when the chair unit 1 is positioned above the bathtub 8 together with the main body 2, the main body 2 is locked at that position so as not to slide.

続いて、本体部２のモータを駆動し、図１５に示すように、椅子ユニット１を浴槽８内へと降下させる。こうして、被介護者は椅子１２に着座したままで、浴槽８内に入り、湯につかることができる。入浴の終了後には、これとは逆に椅子ユニット１を上昇させ、椅子ユニット１が浴槽８の上面を超える位置まで上昇すると、本体部２のスライドのロックを解除し、本体部２を洗場Ｗ側へスライドさせる。そして、本体部２が第１レール部材３２上に移動すると、本体部２を基台３にロックをする。その後、椅子１２を下降後、フットサポート１４及び移動制御部材１３を後方に移動させる。これに続いて、椅子１２をチルト状態から初期状態に戻す。最後に、第２レール部材９と第１レール部材３２とのロックを解除し、被介護者とともに介護用椅子１００を移動させる。 Subsequently, the motor of the main body 2 is driven, and as shown in FIG. 15, the chair unit 1 is lowered into the bathtub 8. In this way, the care recipient can enter the bathtub 8 and soak in hot water while sitting on the chair 12. After bathing, on the contrary, the chair unit 1 is raised, and when the chair unit 1 rises to a position beyond the upper surface of the bathtub 8, the slide of the main body 2 is unlocked and the main body 2 is washed. Slide it to the W side. Then, when the main body portion 2 moves onto the first rail member 32, the main body portion 2 is locked to the base 3. Then, after lowering the chair 12, the foot support 14 and the movement control member 13 are moved backward. Following this, the chair 12 is returned from the tilted state to the initial state. Finally, the lock between the second rail member 9 and the first rail member 32 is released, and the care chair 100 is moved together with the care recipient.

＜４．特徴＞
本実施形態に係る介護用椅子によれば、以下の効果を得ることができる。 <4. Features>
According to the nursing chair according to the present embodiment, the following effects can be obtained.

（１）椅子１２が初期状態にあるときには、フットサポート１４を後退させ、載置部１４２を下方に向けた上で、載置部１４２を支持体１１及び座部１２２の下方に配置することができる。したがって、被介護者が椅子１２に座ったり、椅子１２から立ったりするときに、載置部１４２が被介護者の移動の邪魔になるのを防止することができる。一方、椅子１２を初期状態からチルト状態に移動させると、上述した第１動作制御により、移動制御部材１３がフットサポート１４とともに前方に移動する。したがって、初期状態で、座部１２２の下方に位置していた載置部１４２が、チルト状態において前方に移動するため、フットサポート１４を前方に引き出しやすくすることができる。 (1) When the chair 12 is in the initial state, the foot support 14 may be retracted, the mounting portion 142 may be directed downward, and the mounting portion 142 may be arranged below the support 11 and the seat portion 122. can. Therefore, when the care recipient sits on the chair 12 or stands up from the chair 12, the mounting portion 142 can be prevented from interfering with the movement of the care recipient. On the other hand, when the chair 12 is moved from the initial state to the tilt state, the movement control member 13 moves forward together with the foot support 14 by the first operation control described above. Therefore, since the mounting portion 142 located below the seat portion 122 in the initial state moves forward in the tilted state, the foot support 14 can be easily pulled out forward.

（２）椅子１２が初期状態にあるときには、上述した第２動作制御により、移動制御部材１３を所定長さしか前方に移動できないようになっている。したがって、初期状態にあるときに、フットサポート１４を前方に移動できる距離を適切に規制することができる。 (2) When the chair 12 is in the initial state, the movement control member 13 can be moved forward only by a predetermined length by the above-mentioned second operation control. Therefore, it is possible to appropriately regulate the distance that the foot support 14 can move forward in the initial state.

（３）上述した第３動作制御により、椅子１２がチルト状態にあるときに、移動制御部材１３が第３位置になければ、椅子１２を初期状態に戻すことができないようになっている。したがって、誤操作を防止することができる。 (3) According to the above-mentioned third operation control, when the chair 12 is in the tilted state, the chair 12 cannot be returned to the initial state unless the movement control member 13 is in the third position. Therefore, erroneous operation can be prevented.

（４）上述した第４動作制御により、椅子１２がチルト状態にあるときに、移動制御部材１３が第３位置にあれば、椅子１２を初期状態に戻すのに連動して、移動制御部材１３を第１位置付近まで戻すことができる。したがって、移動制御部材１３を第１位置付近へ戻す手間を省くことができる。 (4) According to the fourth operation control described above, if the movement control member 13 is in the third position when the chair 12 is in the tilted state, the movement control member 13 is interlocked with returning the chair 12 to the initial state. Can be returned to near the first position. Therefore, it is possible to save the trouble of returning the movement control member 13 to the vicinity of the first position.

（５）２個のフットサポート１４を一体ではなく、別々に移動させることができるため、移動の負荷を小さくすることができる。したがって、介護者の負担を軽減することができる。また、被介護者が自身でフットサポート１４を移動することもできる。 (5) Since the two foot supports 14 can be moved separately rather than integrally, the load of movement can be reduced. Therefore, the burden on the caregiver can be reduced. In addition, the care recipient can move the foot support 14 by himself / herself.

＜５．変形例＞
以上、本発明の実施形態について説明したが、本発明は上記各実施形態に限定されるものではなく、その趣旨を逸脱しない限りにおいて、種々の変更が可能である。なお、以下の変形例は、上述した実施形態とともに、適宜組み合わせることができる。 <5. Modification example>
Although the embodiments of the present invention have been described above, the present invention is not limited to the above embodiments, and various modifications can be made without departing from the spirit of the present invention. The following modifications can be appropriately combined with the above-described embodiment.

＜５－１＞
上記実施形態では、椅子に第１係合部と第２係合部が設けられているが、少なくとも第１係合部が設けられていればよく、必要に応じて第２係合部を設ければよい。 <5-1>
In the above embodiment, the chair is provided with the first engaging portion and the second engaging portion, but it is sufficient that at least the first engaging portion is provided, and the second engaging portion is provided as needed. Just do it.

上述した第１係合部１２８の形状は一例であり、移動制御部材１３と係合し、移動制御部材１３を前方に押し出すことができれば、特には限定されない。例えば、図１６（ａ）に示すように、移動制御部材１３の側面に突部１３８を形成し、第１係合部を突部１３８が係合する長穴１５０で構成することができる。これによっても、椅子１２が初期状態からチルト状態に移動する際に、長穴１５０の内壁面が突部１３８を押圧するため、移動制御部材１３を前方に押しやることができる。また、図１６（ｂ）に示すように、椅子１２がチルト状態にあるときに、長穴１５０の先端付近に突部１３８が位置していれば、チルト状態から初期状態に椅子１２を戻すときに、長穴１５０の内壁面が突部１３８を後方に押しやるため、上述した第４動作制御を行うことができる。したがって、この形態では、長穴１５０が第１係合部と第２係合部を兼ねている。 The shape of the first engaging portion 128 described above is an example, and is not particularly limited as long as it can engage with the movement control member 13 and push the movement control member 13 forward. For example, as shown in FIG. 16A, a protrusion 138 may be formed on the side surface of the movement control member 13, and the first engaging portion may be composed of an elongated hole 150 with which the protrusion 138 engages. Also with this, when the chair 12 moves from the initial state to the tilted state, the inner wall surface of the elongated hole 150 presses the protrusion 138, so that the movement control member 13 can be pushed forward. Further, as shown in FIG. 16B, when the chair 12 is in the tilted state, if the protrusion 138 is located near the tip of the elongated hole 150, the chair 12 is returned from the tilted state to the initial state. In addition, since the inner wall surface of the elongated hole 150 pushes the protrusion 138 rearward, the above-mentioned fourth operation control can be performed. Therefore, in this form, the elongated hole 150 serves as both the first engaging portion and the second engaging portion.

第２係合部１２９を設ける場合、第２係合部１２９によって、上述した第２～第４のすべての動作制御が行われる必要はなく、これらの少なくとも１つの動作制御が行えるように、第２係合部１２９の形状、長さ、及び位置、移動制御部材１３の連結部の位置が調整されていればよい。 When the second engaging portion 129 is provided, it is not necessary for the second engaging portion 129 to perform all the above-mentioned second to fourth motion controls, and the second engaging section 129 can control at least one of these motions. 2 The shape, length, and position of the engaging portion 129 and the position of the connecting portion of the movement control member 13 may be adjusted.

上記実施形態で説明した、支持体１１、椅子１２、移動制御部材１３、及びフットサポート１４の形状は一例であり、上述した動作を行うことができるのであれば、種々の形状に変更することができる。 <5-2>
The shapes of the support 11, the chair 12, the movement control member 13, and the foot support 14 described in the above embodiment are examples, and if the above-mentioned operations can be performed, the shapes can be changed to various shapes. can.

＜５－３＞
フットサポート１４において、軸部材１４１の回転を制御する機構は、適宜変更することができる。例えば、図１７に示すように、移動制御部材１３の棒状部材１３１に周方向及び軸方向に延びる溝１３９を形成し、フットサポート１４の軸部材１４１に、棒状部材１３１の溝１３９に係合する突部１４８を形成しておく。これにより、軸部材１４１が前方に移動すると、突部１４８が溝１４７に沿って周方向に回転するため、軸部材１４１の進退とともに回転も動じに行うことができる。あるいは、図１８に示すように、軸部材１４１の端部に周方向に所定間隔をおいて配置された複数の突部１４９を形成し、棒状部材１３１の内壁面に周方向に並ぶ複数の凹部１３８０を形成する。これにより、突部１４９と凹部１３８０の係合位置を変えることで、軸部材１４１を多段階で周方向の回転位置に固定することができる。 <5-3>
In the foot support 14, the mechanism for controlling the rotation of the shaft member 141 can be appropriately changed. For example, as shown in FIG. 17, a groove 139 extending in the circumferential direction and the axial direction is formed in the rod-shaped member 131 of the movement control member 13, and the shaft member 141 of the foot support 14 engages with the groove 139 of the rod-shaped member 131. The protrusion 148 is formed. As a result, when the shaft member 141 moves forward, the protrusion 148 rotates in the circumferential direction along the groove 147, so that the shaft member 141 can be moved forward and backward as well as rotated. Alternatively, as shown in FIG. 18, a plurality of protrusions 149 arranged at predetermined intervals in the circumferential direction are formed at the end of the shaft member 141, and a plurality of recesses arranged in the circumferential direction on the inner wall surface of the rod-shaped member 131. Form 1380. Thereby, by changing the engaging position between the protrusion 149 and the recess 1380, the shaft member 141 can be fixed to the rotational position in the circumferential direction in multiple stages.

本体部２に対して支持体１１を上下動させるための手段は特には限定されず、ラック、ピニオン以外の手段でもよい。また、本体部２が基台３に対してスライドできるように構成しているが、必ずしもこの構成は必要ではなく、単に、基台３上に本体部２を固定し、本体部２に対して支持体が１１上下動できるようにしてもよい。 <5-4>
The means for moving the support 11 up and down with respect to the main body 2 is not particularly limited, and means other than the rack and pinion may be used. Further, although the main body 2 is configured to be slidable with respect to the base 3, this configuration is not always necessary, and the main body 2 is simply fixed on the base 3 with respect to the main body 2. The support may be allowed to move up and down by 11.
