Specifically, the pressing portions 33A1 and 33A2 are portions on the outer peripheral surface of the tubular portion 33 having a larger outer diameter than the relaxation portion 33B described later. In particular, as the pressing portions 33A1 and 33A2, the outer peripheral surface of the tubular portion 33 is used as it is.

筒状部３３は、軸方向の両端部の外周面において押圧部３３Ａ１、３３Ａ２と隣接する位置に緩和部３３Ｂを有する。緩和部３３Ｂは、被押圧部３５への押圧力を押圧部３３Ａ１、３３Ａ２による押圧力よりも緩和する。具体的には、緩和部３３Ｂは、筒状部３３の外周面において、押圧部３３Ａ１、３３Ａ２よりも外径の小さい凹状の部位である。より具体的には、図４に示すように、筒状部３３の外周面には、凹状部３３Ｄ１、３３Ｄ２が設けられている。筒状部３３の凹状部３３Ｄ１、３３Ｄ２との間には、図４に示すように、凸状部３３Ｅが設けられている。かかる凸状部３３Ｅは、中間状態において、本体凸部３１Ｂに当接する。 The tubular portion 33 has relaxation portions 33B at positions adjacent to the pressing portions 33A1 and 33A2 on the outer peripheral surfaces of both end portions in the axial direction. The relaxation unit 33B relieves the pressing force on the pressed portion 35 more than the pressing force by the pressing portions 33A1 and 33A2. Specifically, the relaxation portion 33B is a concave portion having an outer diameter smaller than that of the pressing portions 33A1 and 33A2 on the outer peripheral surface of the tubular portion 33. More specifically, as shown in FIG. 4, concave portions 33D1 and 33D2 are provided on the outer peripheral surface of the tubular portion 33. As shown in FIG. 4, a convex portion 33E is provided between the concave portions 33D1 and 33D2 of the tubular portion 33. The convex portion 33E abuts on the main body convex portion 31B in the intermediate state.

手摺棒支持部３４は、回動支持部材３２の内、手摺棒２６の基端部を支持する部位である。手摺棒支持部３４は、本体部３１のＹ方向の中間部分に設けられた凹状の部位に設けられた正面開口部３１Ｃから、本体部３１の外方（図４におけるＸ方向）へ突出している。手摺棒支持部３４は、かかる正面開口部３１Ｃ内において、手摺棒２６の回動に伴って上下に移動可能とされている。このように、手摺棒支持部３４を介して可動手摺２５の手摺棒２６の回動動作が筒状部３３に伝達されることにより、筒状部３３は、手摺棒２６の下段手摺２１の軸方向を回動中心とした回動に連動して、回動可能とされている。 The handrail rod support portion 34 is a portion of the rotation support member 32 that supports the base end portion of the handrail rod 26. The handrail rod support portion 34 projects outward from the main body portion 31 (in the X direction in FIG. 4) from the front opening portion 31C provided in the concave portion provided in the intermediate portion in the Y direction of the main body portion 31. .. The handrail bar support portion 34 is movable up and down in the front opening 31C as the handrail bar 26 rotates. In this way, the rotational movement of the handrail rod 26 of the movable handrail 25 is transmitted to the tubular portion 33 via the handrail rod support portion 34, so that the tubular portion 33 is the shaft of the lower handrail 21 of the handrail rod 26. It is possible to rotate in conjunction with the rotation centered on the direction.

被押圧部３５が板ばね部材とされることで、下段手摺２１にディンプル（凹凸形状）が設けられている場合等、下段手摺２１の外形寸法が軸方向で変化しても、板ばね部材の弾性変形によって、筒状部３３の変位を吸収できる。下段手摺２１に設けられたディンプルの凹凸の内、凹または凸のいずれの位置でも筒状部３３が下段手摺２１に当接され、固定される際、板ばね部材によって挟持力が適切に設定される。特に、下段手摺２１の凸の位置において筒状部材が固定される際、板ばね部材によって下段手摺２１の樹脂被膜が損傷することを抑制できる。 Since the pressed portion 35 is a leaf spring member, even if the external dimensions of the lower handrail 21 change in the axial direction, such as when the lower handrail 21 is provided with dimples (concavo-convex shape), the leaf spring member The elastic deformation can absorb the displacement of the tubular portion 33. When the tubular portion 33 is brought into contact with the lower handrail 21 and fixed at either the concave or convex position of the dimples provided on the lower handrail 21, the holding force is appropriately set by the leaf spring member. The railing. In particular, when the tubular member is fixed at the convex position of the lower handrail 21, it is possible to prevent the leaf spring member from damaging the resin coating of the lower handrail 21.

（可動手摺の軸方向の移動規制）
次に、図４〜図８を参照しながら、支持部材３０における下段手摺２１の軸方向に沿った移動の規制の具体例について説明する。図４および図５に示すように、可動手摺２５が倒伏状態とされた場合において、突起部３５Ａは筒状部３３の押圧部３３Ａ１に接触し、本体凸部３１Ｂは筒状部３３の凹状部３３Ｄ１に接触している。このため、筒状部３３の中心軸は、本体部３１の開口３１Ａに対してＸ方向に偏心している。これにより、下段手摺２１の−Ｘ方向側の外周面は、筒状部３３の−Ｘ方向側の内周面と接触し、下段手摺２１の＋Ｘ方向側の外周面は、本体部３１の開口３１Ａの＋Ｘ方向側の内周面と接触する。このとき、筒状部３３の押圧部３３Ａによって、被押圧部３５が押圧され、本体部３１は被押圧部３５からの反作用を受ける。これにより、下段手摺２１は、筒状部３３の内周面と本体部３１の開口３１Ａとにより押圧される。 (Axial movement regulation of movable handrail)
Next, with reference to FIGS. 4 to 8, a specific example of regulation of movement of the lower handrail 21 in the support member 30 along the axial direction will be described. As shown in FIGS. 4 and 5, when the movable handrail 25 is in the inverted state, the protrusion 35A comes into contact with the pressing portion 33A1 of the tubular portion 33, and the main body convex portion 31B is the concave portion of the tubular portion 33. It is in contact with 33D1. Therefore, the central axis of the tubular portion 33 is eccentric in the X direction with respect to the opening 31A of the main body portion 31. As a result, the outer peripheral surface of the lower handrail 21 on the −X direction side comes into contact with the inner peripheral surface of the tubular portion 33 on the −X direction side, and the outer peripheral surface of the lower handrail 21 on the + X direction side is the opening of the main body 31. It comes into contact with the inner peripheral surface of 31A on the + X direction side. At this time, the pressed portion 35 is pressed by the pressing portion 33A of the tubular portion 33, and the main body portion 31 receives a reaction from the pressed portion 35. As a result, the lower handrail 21 is pressed by the inner peripheral surface of the tubular portion 33 and the opening 31A of the main body portion 31.

つまり、図５に示すように、可動手摺２５の倒伏状態において、筒状部３３の内周面と本体部３１の開口３１Ａとによって、下段手摺２１が挟持され、筒状部３３および本体部３１の軸方向の移動が規制される。このように、支持部材３０の軸方向の移動が規制される。 That is, as shown in FIG. 5, in the inverted state of the movable handrail 25, the lower handrail 21 is sandwiched between the inner peripheral surface of the tubular portion 33 and the opening 31A of the main body portion 31, and the tubular portion 33 and the main body portion 31 are sandwiched. Axial movement of is restricted. In this way, the axial movement of the support member 30 is restricted.

図６に示すように、可動手摺２５の手摺棒２６が中間状態へ回動された場合において、突起部３５Ａは筒状部３３の緩和部３３Ｂに接触し、本体凸部３１Ｂは筒状部３３の凸状部３３Ｅに接触している。このため、図７に示すように、可動手摺２５が倒伏状態の場合に比べて、筒状部３３の中心軸は、本体部３１の開口３１Ａの中心軸側に寄っている。これにより、筒状部３３の内周面と下段手摺２１の外周面との間には、周全体に亘って間隙が生じ、本体部３１の開口３１Ａが、下段手摺２１から離間する。 As shown in FIG. 6, when the handrail rod 26 of the movable handrail 25 is rotated to the intermediate state, the protrusion 35A contacts the relaxation portion 33B of the tubular portion 33, and the main body convex portion 31B is the tubular portion 33. Is in contact with the convex portion 33E of the. Therefore, as shown in FIG. 7, the central axis of the tubular portion 33 is closer to the central axis side of the opening 31A of the main body portion 31 than in the case where the movable handrail 25 is in the inverted state. As a result, a gap is formed over the entire circumference between the inner peripheral surface of the tubular portion 33 and the outer peripheral surface of the lower handrail 21, and the opening 31A of the main body 31 is separated from the lower handrail 21.

つまり、図７に示すように、可動手摺２５の中間状態において、筒状部３３の内周面と本体部３１の開口３１Ａとによる下段手摺２１の挟持が緩和され、筒状部３３および本体部３１の軸方向の移動規制が解除される。 That is, as shown in FIG. 7, in the intermediate state of the movable handrail 25, the holding of the lower handrail 21 by the inner peripheral surface of the tubular portion 33 and the opening 31A of the main body portion 31 is relaxed, and the tubular portion 33 and the main body portion are alleviated. The axial movement restriction of 31 is lifted.

また、図７に示すように、可動手摺２５の中間状態において、筒状部３３の緩和部３３Ｂに被押圧部３５の突起部３５Ａが入り込んでいる。この場合において、突起部３５Ａの側端面（Ｙ方向端面）と緩和部３３Ｂの凹形状の側壁面（Ｙ方向壁面）とが当接し、筒状部３３と被押圧部３５とが、Ｙ方向に係合した状態となっている。この結果、手摺棒２６を介して手摺棒支持部３４に軸方向の移動の入力があると、筒状部３３から被押圧部３５へ力が伝達され、被押圧部３５の取り付けられた本体部３１も下段手摺２１の軸方向に沿って移動する。 Further, as shown in FIG. 7, in the intermediate state of the movable handrail 25, the protrusion 35A of the pressed portion 35 is inserted into the relaxation portion 33B of the tubular portion 33. In this case, the side end surface (Y direction end surface) of the protrusion 35A and the concave side wall surface (Y direction wall surface) of the relaxation portion 33B are in contact with each other, and the tubular portion 33 and the pressed portion 35 are brought into contact with each other in the Y direction. It is in an engaged state. As a result, when the handrail rod support portion 34 receives an input for axial movement via the handrail rod 26, the force is transmitted from the tubular portion 33 to the pressed portion 35, and the main body portion to which the pressed portion 35 is attached is transmitted. 31 also moves along the axial direction of the lower handrail 21.

図８に示すように、可動手摺２５が起立状態とされると、突起部３５Ａは筒状部３３の押圧部３３Ａ２に接触し、本体凸部３１Ｂは筒状部３３の凹状部３３Ｄ２に接触する。押圧部３３Ａ２と被押圧部３５の突起部３５Ａとが接触すると、被押圧部３５からの反力によって、下段手摺２１は筒状部３３の内周面と本体部３１の開口３１Ａとにより押圧される。 As shown in FIG. 8, when the movable handrail 25 is in the upright state, the protrusion 35A contacts the pressing portion 33A2 of the tubular portion 33, and the main body convex portion 31B contacts the concave portion 33D2 of the tubular portion 33. .. When the pressing portion 33A2 and the protruding portion 35A of the pressed portion 35 come into contact with each other, the lower handrail 21 is pressed by the inner peripheral surface of the tubular portion 33 and the opening 31A of the main body portion 31 due to the reaction force from the pressed portion 35. To.

つまり、図５と同様に、可動手摺２５の起立状態において、筒状部３３の内周面と本体部３１の開口３１Ａとによって下段手摺２１が挟持され、筒状部３３および本体部３１の軸方向の移動が規制される。この結果、支持部材３０の軸方向の移動が規制される。 That is, as in FIG. 5, in the upright state of the movable handrail 25, the lower handrail 21 is sandwiched between the inner peripheral surface of the tubular portion 33 and the opening 31A of the main body portion 31, and the shafts of the tubular portion 33 and the main body portion 31. Directional movement is restricted. As a result, the axial movement of the support member 30 is restricted.

上記の通り、手摺棒２６の起立状態、または倒伏状態にある場合に、本体部３１の所定部分である開口３１Ａの内周面と筒状部３３の内周面とによって、下段手摺２１が挟持され、支持部材３０の軸方向の移動が制限される。これにより、可動手摺２５の起立状態、倒伏状態にある場合に、支持部材３０の軸方向の移動が規制され、可動手摺２５の基端部側での固定が強固に行われる。また、下段手摺２１が開口３１Ａの内周面と筒状部３３の内周面とによって挟持されて固定されるので、下段手摺２１に対し、別途、固定のための構造、加工を加えることなく、可動手摺２５の固定を実現できる。 As described above, when the handrail rod 26 is in the upright state or in the inverted state, the lower handrail 21 is sandwiched between the inner peripheral surface of the opening 31A, which is a predetermined portion of the main body portion 31, and the inner peripheral surface of the tubular portion 33. The axial movement of the support member 30 is restricted. As a result, when the movable handrail 25 is in the upright state or the collapsed state, the movement of the support member 30 in the axial direction is restricted, and the movable handrail 25 is firmly fixed on the base end side. Further, since the lower handrail 21 is sandwiched and fixed by the inner peripheral surface of the opening 31A and the inner peripheral surface of the tubular portion 33, the lower handrail 21 does not need to be separately structurally or processed for fixing. , The movable handrail 25 can be fixed.

また、手摺棒２６と連結した回動支持部材３２によって、回動に伴い本体部３１が変位する結果、開口３１Ａと筒状部３３の内周面とによって下段手摺２１が挟持され、支持部材３０の軸方向の移動が規制される。これにより、手摺棒２６の回動に連動して、可動手摺２５の基端部側での固定が実現される。 Further, as a result of the main body portion 31 being displaced by the rotation support member 32 connected to the handrail rod 26, the lower handrail 21 is sandwiched between the opening 31A and the inner peripheral surface of the tubular portion 33, and the support member 30 Axial movement of is restricted. As a result, the movable handrail 25 is fixed on the base end side in conjunction with the rotation of the handrail rod 26.

なお、板ばね部材である被押圧部３５の強度や、固定ねじによる本体部３１への固定位置の調整によって、下段手摺２１に対する押圧力を調整することができる。 The pressing force on the lower handrail 21 can be adjusted by adjusting the strength of the pressed portion 35, which is a leaf spring member, and the fixing position of the pressed portion 35 with the fixing screw to the main body portion 31.

（壁面ローラ）
続いて、図９、１０を参照しながら、支持部材３０の構成について説明する。図９は、本実施形態に係る支持部材３０の構成例を示す背面図である。図１０は、実施形態に係る支持部材の構成例を示す断面図であり、図９におけるＩＩ−ＩＩ’断面図である。図９に示すように、本体部３１には、さらに壁面ローラ３７が設けられる。壁面ローラ３７は、浴室の浴室壁面１７に接触して転動する回転部材である。壁面ローラ３７は、本体部３１において、浴室の浴室壁面１７と対向する位置（手摺棒２６側とは反対側の位置）に設けられる。壁面ローラ３７は、本体部３１においてＺ方向に挿通されたピン３７Ａに対して軸支されている。図９に示すように、壁面ローラ３７は、本体部３１に４つ設けられている。壁面ローラ３７の外周側は、本体部３１の浴室壁面１７側の端面よりも、浴室壁面１７側に突出している。本体部３１と浴室壁面１７との間に介在された壁面ローラ３７によって可動手摺２５の下段手摺２１の軸方向に移動がより円滑になる。つまり、下段手摺２１と筒状部３３との間には隙間があるため、本体部３１が浴室壁面１７に接触する場合がある。その際、本体部３１が移動の抵抗とならないように壁面ローラ３７がガイドするので、可動手摺２５の位置変更が容易かつ精度よく行える。この結果、固定された手摺が軸方向における最適な位置に提供されるとともに、可動手摺２５の軸方向の移動の規制が解除された後、可動手摺２５をスムーズに移動可能となる。 (Wall roller)
Subsequently, the configuration of the support member 30 will be described with reference to FIGS. 9 and 10. FIG. 9 is a rear view showing a configuration example of the support member 30 according to the present embodiment. FIG. 10 is a cross-sectional view showing a configuration example of the support member according to the embodiment, and is a cross-sectional view taken along the line II-II'in FIG. As shown in FIG. 9, the main body 31 is further provided with a wall roller 37. The wall roller 37 is a rotating member that rolls in contact with the bathroom wall surface 17 of the bathroom. The wall roller 37 is provided in the main body 31 at a position facing the bathroom wall surface 17 of the bathroom (a position opposite to the handrail bar 26 side). The wall roller 37 is pivotally supported by the pin 37A inserted in the Z direction in the main body 31. As shown in FIG. 9, four wall roller 37s are provided on the main body 31. The outer peripheral side of the wall roller 37 projects toward the bathroom wall surface 17 side from the end surface of the main body 31 on the bathroom wall surface 17 side. The wall roller 37 interposed between the main body 31 and the bathroom wall surface 17 facilitates the movement of the lower handrail 21 of the movable handrail 25 in the axial direction. That is, since there is a gap between the lower handrail 21 and the tubular portion 33, the main body portion 31 may come into contact with the bathroom wall surface 17. At that time, since the wall roller 37 guides the main body 31 so as not to act as a resistance to movement, the position of the movable handrail 25 can be easily and accurately changed. As a result, the fixed handrail is provided at the optimum position in the axial direction, and the movable handrail 25 can be smoothly moved after the restriction on the movement of the movable handrail 25 in the axial direction is lifted.

また、壁面ローラ３７は、所定の弾性を有する部材から形成される。例えば、壁面ローラ３７は、合成樹脂、合成ゴム等から形成される。壁面ローラ３７が所定の弾性を有することにより、可動手摺２５が、起立状態または倒伏状態で固定され、本体部３１が浴室壁面１７へ向かって変位する際、壁面ローラ３７が弾性変形し、浴室壁面１７の損傷を防ぐことができ、また、可動手摺２５の起立状態または倒伏状態において、本体部３１が、浴室壁面１７に当接することができる。なお、壁面ローラ３７の数は、浴室壁面１７と本体部３１との円滑な摺動を可能にできればよく、特に限定されない。例えば、壁面ローラ３７は、本体部３１の上下に１つずつ設けられてもよい。 Further, the wall surface roller 37 is formed of a member having a predetermined elasticity. For example, the wall roller 37 is formed of synthetic resin, synthetic rubber, or the like. Since the wall surface roller 37 has a predetermined elasticity, the movable handrail 25 is fixed in an upright state or an inverted state, and when the main body 31 is displaced toward the bathroom wall surface 17, the wall surface roller 37 is elastically deformed and the bathroom wall surface is deformed. Damage to the 17 can be prevented, and the main body 31 can come into contact with the bathroom wall surface 17 when the movable handrail 25 is in an upright or laid-down state. The number of wall rollers 37 is not particularly limited as long as it enables smooth sliding between the bathroom wall surface 17 and the main body 31. For example, one wall roller 37 may be provided above and one below the main body 31.

（手摺ローラ）
図９、図１０に示すように、本体部３１には、さらに手摺ローラ３９が設けられている。手摺ローラ３９は、本体内部においてＸ方向に挿通されたピン３９Ａに対して軸支され、下段手摺２１の外周面に当接しながら転動する回転部材である。手摺ローラ３９が設けられていることで、可動手摺２５の下段手摺２１の軸方向の移動がより円滑になり、可動手摺２５の水平方向の位置変更が容易かつ精度よく行える。この結果、固定された手摺が軸方向における最適な位置に提供される。 (Handrail roller)
As shown in FIGS. 9 and 10, the main body 31 is further provided with a handrail roller 39. The handrail roller 39 is a rotating member that is pivotally supported by a pin 39A inserted in the X direction inside the main body and rolls while abutting on the outer peripheral surface of the lower handrail 21. By providing the handrail roller 39, the lower handrail 21 of the movable handrail 25 can be moved more smoothly in the axial direction, and the horizontal position of the movable handrail 25 can be easily and accurately changed. As a result, the fixed handrail is provided at the optimum position in the axial direction.

特に、手摺ローラ３９は、下段手摺２１の外周面の内、鉛直方向（図１０におけるＺ方向）の上方側の外周面に当接するように、配置される。これにより、本体部３１を含む可動手摺２５の重さによって、手摺ローラ３９が下段手摺２１に当接しやすくなり、より手摺ローラ３９を介した可動手摺２５の移動が円滑になる。従って、可動手摺２５の水平方向の位置変更が容易かつ精度よく行える。この結果、固定された手摺が軸方向における最適な位置に提供されるとともに、可動手摺２５の軸方向の移動の規制が解除された後、可動手摺２５をスムーズに移動可能となる。 In particular, the handrail roller 39 is arranged so as to abut on the outer peripheral surface on the upper side in the vertical direction (Z direction in FIG. 10) in the outer peripheral surface of the lower handrail 21. As a result, the weight of the movable handrail 25 including the main body 31 makes it easier for the handrail roller 39 to come into contact with the lower handrail 21, and the movable handrail 25 can move more smoothly through the handrail roller 39. Therefore, the position of the movable handrail 25 in the horizontal direction can be easily and accurately changed. As a result, the fixed handrail is provided at the optimum position in the axial direction, and the movable handrail 25 can be smoothly moved after the restriction on the movement of the movable handrail 25 in the axial direction is lifted.

（固定部材）
引き続き、図３、図１１〜図１３を参照しながら、固定部材４０について説明する。図１１は、本実施形態に係る倒伏状態における固定部材４０による固定の様子を示す断面図であり、図１におけるＩＩＩ−ＩＩＩ’断面図である。図１２および図１３は、本実施形態に係る起立状態における係止部材５０による固定の様子を示す断面図であり、図２におけるＩＶ−ＩＶ’断面図である。図３に示すように、可動手摺２５の先端部側には、固定部材４０が設けられている。固定部材４０は、可動手摺２５の倒伏状態において、可動手摺２５の先端部の下方側に位置する。固定部材４０は、可動手摺２５の倒伏状態において、可動手摺２５を浴槽１０の側壁１１の上部に対して固定する。 (Fixing member)
Subsequently, the fixing member 40 will be described with reference to FIGS. 3 and 11 to 13. FIG. 11 is a cross-sectional view showing a state of fixing by the fixing member 40 in the collapsed state according to the present embodiment, and is a cross-sectional view taken along the line III-III'in FIG. 12 and 13 are cross-sectional views showing a state of fixing by the locking member 50 in the upright state according to the present embodiment, and is a cross-sectional view taken along the line IV-IV'in FIG. As shown in FIG. 3, a fixing member 40 is provided on the tip end side of the movable handrail 25. The fixing member 40 is located on the lower side of the tip end portion of the movable handrail 25 in the inverted state of the movable handrail 25. The fixing member 40 fixes the movable handrail 25 to the upper part of the side wall 11 of the bathtub 10 in the inverted state of the movable handrail 25.

図１１に示すように、固定部材４０は、載置部４１と、保持部４３とを有する。載置部４１は、可動手摺２５の倒伏状態において浴槽１０の側壁１１の上壁面１３に載置される部位である。可動手摺２５は、載置部４１を介して浴槽１０の上壁面１３に載置される。載置部４１の上壁面１３と対向する面には、合成ゴム等の弾性体から成るシート状部材が取り付けられている。載置部４１は、先端が所定の曲率をもって上壁面１３側へ向かって湾曲している。 As shown in FIG. 11, the fixing member 40 has a mounting portion 41 and a holding portion 43. The mounting portion 41 is a portion to be mounted on the upper wall surface 13 of the side wall 11 of the bathtub 10 in the inverted state of the movable handrail 25. The movable handrail 25 is mounted on the upper wall surface 13 of the bathtub 10 via the mounting portion 41. A sheet-like member made of an elastic body such as synthetic rubber is attached to the surface of the mounting portion 41 facing the upper wall surface 13. The tip of the mounting portion 41 is curved toward the upper wall surface 13 side with a predetermined curvature.

保持部４３は、可動手摺２５の倒伏状態において浴槽１０の側壁１１の外面に配置可能とされている。保持部４３は、載置部４１との間で浴槽１０の側壁１１を保持する。これにより、可動手摺２５を浴槽１０に対して強固に固定することが可能となる。 The holding portion 43 can be arranged on the outer surface of the side wall 11 of the bathtub 10 in the inverted state of the movable handrail 25. The holding portion 43 holds the side wall 11 of the bathtub 10 with the mounting portion 41. This makes it possible to firmly fix the movable handrail 25 to the bathtub 10.

具体的には、保持部４３は、浴槽１０の溝部１５に挿入可能とされる。より具体的には、保持部４３の先端部は、浴槽１０の溝部１５内に収容され、溝部１５の上面と当接する係合部４３Ａとなっている。これにより、上壁面１３に載置された載置部４１と保持部４３の係合部４３Ａとが側壁１１を挟持することで可動手摺２５が固定される。この結果、可動手摺２５を浴槽１０に対してより強固に固定することが可能となる。 Specifically, the holding portion 43 can be inserted into the groove portion 15 of the bathtub 10. More specifically, the tip portion of the holding portion 43 is accommodated in the groove portion 15 of the bathtub 10 and serves as an engaging portion 43A that abuts on the upper surface of the groove portion 15. As a result, the movable handrail 25 is fixed by the mounting portion 41 mounted on the upper wall surface 13 and the engaging portion 43A of the holding portion 43 sandwiching the side wall 11. As a result, the movable handrail 25 can be more firmly fixed to the bathtub 10.

固定部材４０は、さらに調整機構４５を有している。調整機構４５は、載置部４１に対する保持部４３の係合部４３Ａの位置を調整する機構である。保持部４３の位置が調整されることで、固定部材４０の挟持力を調節することができ、また、浴槽１０の溝部１５の位置が変化しても、保持部４３の係合部４３Ａを溝部１５内に収容されるようにできる。 The fixing member 40 further has an adjusting mechanism 45. The adjusting mechanism 45 is a mechanism for adjusting the position of the engaging portion 43A of the holding portion 43 with respect to the mounting portion 41. By adjusting the position of the holding portion 43, the holding force of the fixing member 40 can be adjusted, and even if the position of the groove portion 15 of the bathtub 10 changes, the engaging portion 43A of the holding portion 43 is grooved. It can be accommodated within 15.

固定部材４０は、さらに回動機構４７を有している。回動機構４７は、保持部４３を回動させるための機構である。固定部材４０は、回動機構４７によって、待避位置と保持位置との間で回動可能とされている。ここで、保持位置とは、倒伏状態において保持部４３が浴槽１０の側壁１１の外面に配置された位置である。より具体的には、保持位置とは、溝部１５内に保持部４３の係合部４３Ａが収容される位置である。また、待避位置とは、可動手摺２５の倒伏状態において保持部４３が保持位置から待避して浴槽１０の側壁１１の保持が解除される位置である。より具体的には、待避位置とは、保持部４３が保持位置から所定角度（本例は略９０度）回動して係合部４３Ａが溝部１５から離脱した位置である。また、保持位置の保持部４３が待避位置に向けて略４５度回動されることで、可動手摺２５が起立状態から倒伏状態へと回動されるとき、保持部４３が浴槽１０の側壁１１と干渉することが防止される。また、可動手摺２５の倒伏状態から起立状態へと回動されるときも、保持部４３と浴槽１０との干渉を防止できる。このように、可動手摺２５の起立状態、倒伏状態の切り替えが、スムーズに行われる。なお、固定部材４０には、保持部４３を保持位置にロック可能なロック手段（図示せず）が設けられている。 The fixing member 40 further has a rotating mechanism 47. The rotation mechanism 47 is a mechanism for rotating the holding portion 43. The fixing member 40 is made rotatable between the shunting position and the holding position by the rotating mechanism 47. Here, the holding position is a position where the holding portion 43 is arranged on the outer surface of the side wall 11 of the bathtub 10 in the inverted state. More specifically, the holding position is a position where the engaging portion 43A of the holding portion 43 is housed in the groove portion 15. Further, the shunting position is a position where the holding portion 43 shunts from the holding position in the inverted state of the movable handrail 25 and the side wall 11 of the bathtub 10 is released from being held. More specifically, the shunting position is a position where the holding portion 43 is rotated by a predetermined angle (approximately 90 degrees in this example) from the holding position and the engaging portion 43A is separated from the groove portion 15. Further, when the movable handrail 25 is rotated from the upright state to the prone state by rotating the holding portion 43 at the holding position by approximately 45 degrees toward the shunting position, the holding portion 43 is moved to the side wall 11 of the bathtub 10. Is prevented from interfering with. Further, even when the movable handrail 25 is rotated from the inverted state to the upright state, interference between the holding portion 43 and the bathtub 10 can be prevented. In this way, the movable handrail 25 can be smoothly switched between the upright state and the prone state. The fixing member 40 is provided with a locking means (not shown) capable of locking the holding portion 43 at the holding position.

（係止部材）
図３に示すように、可動手摺２５の先端部側には、係止部材５０が設けられている。係止部材５０は、可動手摺２５の倒伏状態において、可動手摺２５の先端部の上方側に位置する。係止部材５０は、可動手摺２５の起立状態において、可動手摺２５を上段手摺２３に対して固定または固定解除する。 (Locking member)
As shown in FIG. 3, a locking member 50 is provided on the tip end side of the movable handrail 25. The locking member 50 is located on the upper side of the tip end portion of the movable handrail 25 in the inverted state of the movable handrail 25. The locking member 50 fixes or releases the movable handrail 25 to the upper handrail 23 in the upright state of the movable handrail 25.

係止部材５０は、筐体部５１を有している。図１２に示すように、可動手摺２５の起立状態において、筐体部５１の壁部と対向する面には、凹部５３が設けられている。凹部５３は、断面視（図１２におけるＸ−Ｚ平面断面視）で略半円形状を有し、上段手摺２３へ向かって開放されている。可動手摺２５の起立状態において、凹部５３内には上段手摺２３が収容される。凹部５３の周面の一部には凹部開口５３Ａが設けられている。かかる凹部開口５３Ａから後述する押さえ部５５が出没可能とされており、可動手摺２５の起立状態において上段手摺２３に向かって突出可能とされている。図１３に示すように、押さえ部５５が凹部開口５３Ａから突出された状態で、押さえ部５５と上段手摺２３とが係合する。具体的には、押さえ部５５が上段手摺２３を押圧する。これにより、凹部５３が上段手摺２３から外れる方向に移動不能とされるとともに、上段手摺２３の軸方向に沿った移動も規制される。この結果、可動手摺２５は、上段手摺２３に対して固定される。この結果、可動手摺２５が起立状態で固定された手摺として機能する。また、押さえ部５５が、図１２に示すように凹部開口５３Ａ内に没入すると、上段手摺２３に対する固定が解除される。 The locking member 50 has a housing portion 51. As shown in FIG. 12, in the upright state of the movable handrail 25, a recess 53 is provided on the surface of the housing portion 51 facing the wall portion. The recess 53 has a substantially semicircular shape in a cross-sectional view (XZ plane cross-sectional view in FIG. 12), and is open toward the upper handrail 23. In the upright state of the movable handrail 25, the upper handrail 23 is housed in the recess 53. A recess opening 53A is provided on a part of the peripheral surface of the recess 53. The pressing portion 55, which will be described later, can be retracted from the recessed opening 53A, and can protrude toward the upper handrail 23 in the upright state of the movable handrail 25. As shown in FIG. 13, the pressing portion 55 and the upper handrail 23 are engaged with each other in a state where the pressing portion 55 protrudes from the recess opening 53A. Specifically, the pressing portion 55 presses the upper handrail 23. As a result, the recess 53 is made immovable in the direction away from the upper handrail 23, and the movement of the upper handrail 23 along the axial direction is also restricted. As a result, the movable handrail 25 is fixed to the upper handrail 23. As a result, the movable handrail 25 functions as a fixed handrail in an upright state. Further, when the pressing portion 55 is immersed in the recess opening 53A as shown in FIG. 12, the fixing to the upper handrail 23 is released.

（連動機構）
本実施形態に係る浴室手摺構造２０の可動手摺２５は、さらに連動機構６０を備えている。図１２および図１３に示すように、連動機構６０は、手摺棒２６の先端部側において、固定部材４０から係止部材５０にかけて設けられている。連動機構６０は、保持部４３と押さえ部５５とを機械的に連結し、保持部４３の動作を押さえ部５５の動作に連動可能としている。連動機構６０は、保持部４３の保持位置と、待避位置との間の変位に連動して、可動手摺２５の起立状態において、係止部材５０を上段手摺２３に対して固定及び固定解除させる。 (Interlocking mechanism)
The movable handrail 25 of the bathroom handrail structure 20 according to the present embodiment further includes an interlocking mechanism 60. As shown in FIGS. 12 and 13, the interlocking mechanism 60 is provided from the fixing member 40 to the locking member 50 on the tip end side of the handrail rod 26. The interlocking mechanism 60 mechanically connects the holding portion 43 and the pressing portion 55 so that the operation of the holding portion 43 can be interlocked with the operation of the pressing portion 55. The interlocking mechanism 60 fixes and releases the locking member 50 to the upper handrail 23 in the upright state of the movable handrail 25 in conjunction with the displacement between the holding position of the holding portion 43 and the shunting position.

具体的には、連動機構６０は、一例として、長尺な板状の連結部材６１と、断面Ｔ字状のガイド部材６３と、板状のリンク部材６５と、を有している。連結部材６１の一端は、固定部材４０の回動機構４７と連結され、他端は、ガイドピン６１Ａによりリンク部材６５の一端側に連結されている。リンク部材６５の他端側は凹部５３に対して固定部材４０側かつ支持部材３０側において係止部材５０に対して回動可能に支持されている。図１３に示すように、ガイド部材６３にはＸ方向に延びるガイド孔６３Ａが設けられている。このガイド孔６３Ａにはガイドピン６１Ａが挿通されている。また、ガイド部材６３は係止部材５０の筐体部５１内にＺ方向に摺動可能に設けられている。 Specifically, the interlocking mechanism 60 has, for example, a long plate-shaped connecting member 61, a guide member 63 having a T-shaped cross section, and a plate-shaped link member 65. One end of the connecting member 61 is connected to the rotating mechanism 47 of the fixing member 40, and the other end is connected to one end side of the link member 65 by the guide pin 61A. The other end side of the link member 65 is rotatably supported with respect to the locking member 50 on the fixing member 40 side and the support member 30 side with respect to the recess 53. As shown in FIG. 13, the guide member 63 is provided with a guide hole 63A extending in the X direction. A guide pin 61A is inserted through the guide hole 63A. Further, the guide member 63 is slidably provided in the housing portion 51 of the locking member 50 in the Z direction.

固定部材４０の保持部４３が保持位置（図１２参照）から待避位置（図１３参照）へと回動されると、固定部材４０の回動機構４７を介して連結部材６１が＋Ｘ方向に変位する。連結部材６１のＸ方向の変位によって、ガイドピン６１Ａも＋Ｘ方向に移動する。ただし、ガイドピン６１Ａはリンク部材６５に対して固定されているため、＋Ｘ方向の移動に伴いリンク部材６５の回動に合わせて＋Ｚ方向に変位する。ガイドピン６１Ａが＋Ｘ方向かつ＋Ｚ方向に変位すると、ガイドピン６１Ａはガイド孔６３Ａを＋Ｘ方向に移動しつつ、ガイド部材６３を＋Ｚ方向に変位させる。これにより、ガイド部材６３に設けられた押さえ部５５が凹部５３内に突出する。また、ガイドピン６１Ａがリンク部材６５の上死点に位置するので、上段手摺２３の−Ｚ方向への反発に抗して強固に上段手摺２３を保持することができる。 When the holding portion 43 of the fixing member 40 is rotated from the holding position (see FIG. 12) to the shunting position (see FIG. 13), the connecting member 61 is displaced in the + X direction via the rotating mechanism 47 of the fixing member 40. To do. The guide pin 61A also moves in the + X direction due to the displacement of the connecting member 61 in the X direction. However, since the guide pin 61A is fixed to the link member 65, it is displaced in the + Z direction in accordance with the rotation of the link member 65 as it moves in the + X direction. When the guide pin 61A is displaced in the + X direction and the + Z direction, the guide pin 61A displaces the guide member 63 in the + Z direction while moving the guide hole 63A in the + X direction. As a result, the pressing portion 55 provided on the guide member 63 projects into the recess 53. Further, since the guide pin 61A is located at the top dead center of the link member 65, the upper handrail 23 can be firmly held against the repulsion of the upper handrail 23 in the −Z direction.

固定部材４０の保持部４３が待避位置（図１３参照）から保持位置（図１２参照）へと回動されると、固定部材４０の回動機構４７を介して連結部材６１が−Ｘ方向に変位する。連結部材６１のＸ方向の変位によって、ガイドピン６１Ａも−Ｘ方向に移動する。ただし、ガイドピン６１Ａはリンク部材６５に対して固定されているため、−Ｘ方向の移動に伴いリンク部材６５の回動に合わせて−Ｚ方向に変位する。ガイドピン６１Ａが−Ｘ方向かつ−Ｚ方向に変位すると、ガイドピン６１Ａはガイド孔６３Ａを−Ｘ方向に移動しつつ、ガイド部材６３を−Ｚ方向に変位させる。これにより、ガイド部材６３に設けられた押さえ部５５が凹部５３内に突出されなくなる。連動機構６０によって、保持部４３の変位に連動して、係止部材５０の上段手摺２３に対する固定およびその解除が実現される。これにより、可動手摺２５を起立状態で固定するために、別途操作部を設ける必要がなくなる。また、保持部４３の変位に基づいて可動手摺２５の固定状態が判別可能となるので、起立状態での可動手摺２５の固定し忘れが防止でき、固定が確実に行われる。また、係止部材５０における固定、解除が簡便に行われ、可動手摺２５の軸方向の移動がしやすくなる。 When the holding portion 43 of the fixing member 40 is rotated from the retaining position (see FIG. 13) to the holding position (see FIG. 12), the connecting member 61 moves in the −X direction via the rotating mechanism 47 of the fixing member 40. Displace. Due to the displacement of the connecting member 61 in the X direction, the guide pin 61A also moves in the −X direction. However, since the guide pin 61A is fixed to the link member 65, it is displaced in the −Z direction in accordance with the rotation of the link member 65 as it moves in the −X direction. When the guide pin 61A is displaced in the −X direction and the −Z direction, the guide pin 61A displaces the guide member 63 in the −Z direction while moving the guide hole 63A in the −X direction. As a result, the pressing portion 55 provided on the guide member 63 does not protrude into the recess 53. The interlocking mechanism 60 realizes the fixing of the locking member 50 to the upper handrail 23 and the release thereof in conjunction with the displacement of the holding portion 43. As a result, in order to fix the movable handrail 25 in the upright state, it is not necessary to separately provide an operation unit. Further, since the fixed state of the movable handrail 25 can be determined based on the displacement of the holding portion 43, it is possible to prevent forgetting to fix the movable handrail 25 in the upright state, and the movable handrail 25 is surely fixed. Further, the locking member 50 can be easily fixed and released, and the movable handrail 25 can be easily moved in the axial direction.

（把持部）
本実施形態に係る浴室手摺構造２０の可動手摺２５は、さらに把持部７０を備えている。図１及び図３に示すように、把持部７０は、手摺棒２６の先端部側に設けられ、浴槽１０の利用者によって把持可能とされた部位である。特に可動手摺２５が倒伏状態にある場合に、把持部７０は、利用者によって手摺として使用される。例えば、入出槽において、浴槽１０の側壁１１を跨ぐ動作をする時、把持部７０は、利用者が体を支えるための手摺として利用される。 (Grip part)
The movable handrail 25 of the bathroom handrail structure 20 according to the present embodiment further includes a grip portion 70. As shown in FIGS. 1 and 3, the grip portion 70 is provided on the tip end side of the handrail rod 26 and is a portion that can be gripped by the user of the bathtub 10. In particular, when the movable handrail 25 is in an inverted state, the grip portion 70 is used as a handrail by the user. For example, in the entry / exit tank, when the operation is performed across the side wall 11 of the bathtub 10, the grip portion 70 is used as a handrail for the user to support the body.

具体的には、把持部７０は、係止部材５０の筐体部側壁５１Ａに設けられている。把持部７０は、可動手摺２５の倒伏状態で、平面視（図１におけるＺ方向視）で、環状を有するハンドルである。図１に示すように、把持部７０の円弧状の端部は、係止部材５０の筐体部側壁５１Ａに取り付けられ、円弧の中間部を利用者が把持可能とされている。 Specifically, the grip portion 70 is provided on the side wall 51A of the housing portion of the locking member 50. The grip portion 70 is a handle having an annular shape in a plan view (Z direction view in FIG. 1) in a tilted state of the movable handrail 25. As shown in FIG. 1, the arcuate end of the grip 70 is attached to the side wall 51A of the housing portion of the locking member 50 so that the user can grip the middle portion of the arc.

また、把持部７０が係止部材５０に設けられることにより、浴槽１０の側壁１１の上方に把持部７０が位置する。この結果、側壁１１を跨ぐ動作の際に、把持部７０が手摺として有効に機能する。さらに、把持部７０が係止部材５０に設けられることで、可動手摺２５の起立状態と倒伏状態との間の位置変更操作において操作がしやすくなり、下段手摺２１の軸方向に沿った方向に可動手摺２５を移動させる際にも、把持部７０を使用できる。 Further, since the grip portion 70 is provided on the locking member 50, the grip portion 70 is located above the side wall 11 of the bathtub 10. As a result, the grip portion 70 effectively functions as a handrail when straddling the side wall 11. Further, since the grip portion 70 is provided on the locking member 50, it becomes easier to operate the movable handrail 25 in the position changing operation between the upright state and the tilted state, and the lower handrail 21 is oriented in the axial direction. The grip portion 70 can also be used when moving the movable handrail 25.

（浴室手摺構造の操作例）
続いて、本実施形態に係る浴室手摺構造２０の操作例について、図１、図２、および図１４を参照しながら、説明する。まず、倒伏状態にある可動手摺２５（図１参照）を、起立状態（図２参照）へと切り替える操作について説明する。この場合、浴槽１０の利用者または介助者（以下、操作者という）は、手摺棒２６の先端部側に設けられた固定部材４０による固定を解除する。具体的には、固定部材４０による浴槽１０の側壁１１の保持が解除された後、操作者によって、可動手摺２５は、下段手摺２１を回転軸として、起立状態へと回動される。 (Operation example of bathroom handrail structure)
Subsequently, an operation example of the bathroom handrail structure 20 according to the present embodiment will be described with reference to FIGS. 1, 2, and 14. First, an operation of switching the movable handrail 25 (see FIG. 1) in the lying down state to the standing state (see FIG. 2) will be described. In this case, the user or caregiver of the bathtub 10 (hereinafter referred to as an operator) releases the fixing by the fixing member 40 provided on the tip end side of the handrail rod 26. Specifically, after the holding of the side wall 11 of the bathtub 10 by the fixing member 40 is released, the movable handrail 25 is rotated to the upright state by the operator with the lower handrail 21 as the rotation axis.

図２に示すように、可動手摺２５が起立状態とされた時、上段手摺２３は、係止部材５０の凹部５３内に収容される。この状態で、操作者によって固定部材４０の保持部４３の保持位置から待避位置への変位が行われると、係止部材５０の凹部５３の開放側端部から押さえ部５５が突出する。この結果、可動手摺２５が、起立状態で上段手摺２３に対して固定される。つまり、可動手摺２５が起立状態で固定された手摺として機能する。また、ロック手段により保持位置の保持部４３がロックされるので、利用者が保持部４３に手をかけても、係止部材５０が上段手摺２３から外れない。 As shown in FIG. 2, when the movable handrail 25 is in the upright state, the upper handrail 23 is housed in the recess 53 of the locking member 50. In this state, when the operator displaces the holding portion 43 of the fixing member 40 from the holding position to the shunting position, the pressing portion 55 projects from the open side end of the recess 53 of the locking member 50. As a result, the movable handrail 25 is fixed to the upper handrail 23 in the upright state. That is, the movable handrail 25 functions as a fixed handrail in an upright state. Further, since the holding portion 43 at the holding position is locked by the locking means, the locking member 50 does not come off from the upper handrail 23 even if the user puts his / her hand on the holding portion 43.

次に、起立状態にある可動手摺２５（図２参照）を倒伏状態（図１参照）に切り替える場合について説明する。まず、操作者によって、ロック手段が解除されて保持部４３の待避位置から保持位置への変位が行われる。これにより、係止部材５０の押さえ部５５が凹部５３の開放側端部で突出しなくなり、押さえ部５５と上段手摺２３の外周面との係合が解除される。つまり、可動手摺２５の起立状態での上段手摺２３に対する固定が解除される。その後、操作者によって手摺棒２６は下段手摺２１を回動軸として倒伏状態へと回動される。 Next, a case where the movable handrail 25 (see FIG. 2) in the standing state is switched to the lying state (see FIG. 1) will be described. First, the operator releases the locking means and displaces the holding portion 43 from the retreating position to the holding position. As a result, the pressing portion 55 of the locking member 50 does not protrude at the open side end of the recess 53, and the engagement between the pressing portion 55 and the outer peripheral surface of the upper handrail 23 is released. That is, the movable handrail 25 is released from being fixed to the upper handrail 23 in the upright state. After that, the handrail rod 26 is rotated by the operator to the inverted state with the lower handrail 21 as the rotation axis.

図１に示すように、可動手摺２５が倒伏状態とされた時、固定部材４０の載置部４１は、浴槽１０の上壁面１３と当接している。すなわち、可動手摺２５の先端部側は、浴槽１０の側壁１１に対して支持されている。この状態で操作者によって固定部材４０の固定操作が行われる。具体的には、固定部材４０の保持部４３が、溝部１５へ掛止される。この結果、載置部４１と保持部４３とで浴槽１０の側壁１１が保持され、可動手摺２５は浴槽１０に固定される。また、倒伏状態の可動手摺２５では支持部材３０が下段手摺２１の軸方向の移動も規制されている。したがって、可動手摺２５が倒伏状態で固定された手摺として機能する。 As shown in FIG. 1, when the movable handrail 25 is in the inverted state, the mounting portion 41 of the fixing member 40 is in contact with the upper wall surface 13 of the bathtub 10. That is, the tip end side of the movable handrail 25 is supported with respect to the side wall 11 of the bathtub 10. In this state, the operator performs the fixing operation of the fixing member 40. Specifically, the holding portion 43 of the fixing member 40 is hooked on the groove portion 15. As a result, the side wall 11 of the bathtub 10 is held by the mounting portion 41 and the holding portion 43, and the movable handrail 25 is fixed to the bathtub 10. Further, in the movable handrail 25 in the collapsed state, the movement of the support member 30 in the axial direction of the lower handrail 21 is also restricted. Therefore, the movable handrail 25 functions as a fixed handrail in the inverted state.

続いて、図１４を参照しながら、可動手摺２５を下段手摺２１に対して移動させ、水平方向（図１４におけるＹ方向）の位置を変更する操作について説明する。図１４は、実施形態に係る可動手摺の動作例を示す斜視図である。まず、操作者によって、中間状態に手摺棒２６が回動される。起立状態または倒伏状態から中間状態へと手摺棒２６を回動させると、支持部材３０が下段手摺２１の軸方向（図１４におけるＹ方向）の固定が解除される。つまり、この状態では、可動手摺２５は、下段手摺２１の軸方向に移動可能である。 Subsequently, with reference to FIG. 14, an operation of moving the movable handrail 25 with respect to the lower handrail 21 to change the position in the horizontal direction (Y direction in FIG. 14) will be described. FIG. 14 is a perspective view showing an operation example of the movable handrail according to the embodiment. First, the operator rotates the handrail rod 26 in the intermediate state. When the handrail rod 26 is rotated from the upright state or the inverted state to the intermediate state, the support member 30 is released from being fixed in the axial direction (Y direction in FIG. 14) of the lower handrail 21. That is, in this state, the movable handrail 25 can move in the axial direction of the lower handrail 21.

これにより、手摺棒２６を浴槽１０に架け渡す位置が変更可能となる。これにより、可動手摺２５を様々な位置に設けることができ、浴槽１０の利用者の姿勢、動作に合わせて固定された手摺が提供される。 As a result, the position where the handrail rod 26 is bridged over the bathtub 10 can be changed. As a result, the movable handrail 25 can be provided at various positions, and a handrail fixed according to the posture and movement of the user of the bathtub 10 is provided.

また、中間状態では、手摺棒２６が、浴室壁面１７に対して鉛直方向から斜めとなった状態で支持部材３０を下段手摺２１の軸方向に移動できる。つまり、操作者が、浴室床面１９に立った状態のままで、可動手摺２５を操作することが可能となる。これにより、可動手摺２５の移動に際し、操作者が浴槽１０に入って可動手摺２５を操作する必要がない。この結果、固定された手摺を水平方向の様々な位置に設けることが容易となる。 Further, in the intermediate state, the handrail rod 26 can move the support member 30 in the axial direction of the lower handrail 21 in a state where the handrail rod 26 is oblique from the vertical direction with respect to the bathroom wall surface 17. That is, the operator can operate the movable handrail 25 while standing on the bathroom floor surface 19. As a result, when moving the movable handrail 25, it is not necessary for the operator to enter the bathtub 10 and operate the movable handrail 25. As a result, it becomes easy to provide the fixed handrails at various positions in the horizontal direction.

また、図１４に示すように、可動手摺２５の基端部は、手摺棒支持部３４において、下段手摺２１の軸方向と直交する方向を回転軸として回動可能とされる。これにより、可動手摺２５を下段手摺２１の軸方向に移動させる際に、下段手摺２１との干渉（基端部でのモーメントによる齧り）が起きにくく、円滑な移動が実現される。 Further, as shown in FIG. 14, the base end portion of the movable handrail 25 is rotatable in the handrail rod support portion 34 with a direction orthogonal to the axial direction of the lower handrail 21 as a rotation axis. As a result, when the movable handrail 25 is moved in the axial direction of the lower handrail 21, interference with the lower handrail 21 (biting due to the moment at the base end portion) is less likely to occur, and smooth movement is realized.

（作用効果）
本実施形態に係る浴室手摺構造２０によれば、可動手摺２５の起立状態においては、主に入出槽時に利用者が利用可能であり、可動手摺２５の倒伏状態においては入浴中に利用者が利用することができる。したがって、利用者の入浴時及び入浴中の様々な姿勢、並びに動作に合わせて固定された手摺を提供することができる。 (Action effect)
According to the bathroom handrail structure 20 according to the present embodiment, the movable handrail 25 can be used mainly by the user when entering and exiting the tank in the upright state, and can be used by the user while taking a bath in the inverted state of the movable handrail 25. can do. Therefore, it is possible to provide a handrail that is fixed according to various postures and movements of the user during and during bathing.

また、本実施形態に係る浴室手摺構造２０によれば、起立状態と倒伏状態とで固定された手摺を別々に設けずに済み、浴室内の省スペース化も実現される。 Further, according to the bathroom handrail structure 20 according to the present embodiment, it is not necessary to separately provide the handrails fixed in the standing state and the lying state, and the space in the bathroom can be saved.

また、本実施形態に係る浴室手摺構造２０によれば、可動手摺２５が起立状態にある場合に、本体部３１によって下段手摺２１が押圧され、筒状部３３の軸方向の移動が制限される。これにより、可動手摺２５が起立状態にある場合に、筒状部３３を含めた支持部材３０の軸方向の移動が規制され、可動手摺２５の基端部側での固定が簡便に行われる。また、可動手摺２５が倒伏状態にある場合にも同様に、筒状部３３の軸方向の移動が制限されることにより、筒状部３３を含めた支持部材３０の軸方向の移動が規制され、可動手摺２５の基端部側での固定が簡便に行われる。 Further, according to the bathroom handrail structure 20 according to the present embodiment, when the movable handrail 25 is in the upright state, the lower handrail 21 is pressed by the main body portion 31, and the axial movement of the tubular portion 33 is restricted. .. As a result, when the movable handrail 25 is in the upright state, the movement of the support member 30 including the tubular portion 33 in the axial direction is restricted, and the movable handrail 25 can be easily fixed on the base end side. Similarly, even when the movable handrail 25 is in the inverted state, the axial movement of the tubular portion 33 is restricted, so that the axial movement of the support member 30 including the tubular portion 33 is restricted. , The movable handrail 25 can be easily fixed on the base end side.

また、本実施形態に係る浴室手摺構造２０によれば、手摺棒２６と連結した回動支持部材３２によって回動に伴い本体部３１が変位する結果、開口３１Ａによって下段手摺２１が押圧され、支持部材３０の軸方向の移動が規制される。これにより、手摺棒２６の回動に連動して可動手摺２５の基端部側での固定が実現されるので、可動手摺２５の軸方向の移動の規制、その解除が簡便に行われる。 Further, according to the bathroom handrail structure 20 according to the present embodiment, as a result of the main body 31 being displaced by the rotation support member 32 connected to the handrail rod 26, the lower handrail 21 is pressed and supported by the opening 31A. The axial movement of the member 30 is restricted. As a result, the movable handrail 25 is fixed on the base end side in conjunction with the rotation of the handrail rod 26, so that the movement of the movable handrail 25 in the axial direction is restricted and released easily.
