　図１は、仮設手すり１０の斜視図である。図２は、仮設手すり１０の平面図である。仮設手すり１０は、図１に示されているように、ベースプレート１１と、手すり１２，１３とを備えている。この仮設手すり１０は、図１に示されているように、トイレ１００の前方に設置される。ここでは、トイレ１００の便座側から、前方に配置された仮設手すり１０を見た状態で、仮設手すり１０の前後左右が定められている。図１および図２に示された例では、便器に座った態勢の使用者の左側に配置された手すりを「左側の手すり」とし、使用者の右側に配置された手すりを「右側の手すり」とする。左側の手すり１２は、ベースプレート１１の左側において後方かつ外側の予め定められた位置に配置されている。右側の手すり１３は、ベースプレート１１の右側において前方かつ内側の予め定められた位置に配置されている。 FIG. 1 is a perspective view of the temporary handrail 10. FIG. 2 is a plan view of the temporary handrail 10. As shown in FIG. 1, the temporary handrail 10 includes a base plate 11 and handrails 12 and 13. The temporary handrail 10 is installed in front of the toilet 100 as shown in FIG. Here, the front, back, left, and right of the temporary handrail 10 are defined while looking at the temporary handrail 10 arranged in front from the toilet seat side of the toilet 100. In the examples shown in FIGS. 1 and 2, the handrail placed on the left side of the user sitting on the toilet bowl is referred to as the "left handrail", and the handrail placed on the right side of the user is referred to as the "right handrail". And. The left handrail 12 is located posteriorly and outwardly at predetermined positions on the left side of the base plate 11. The right handrail 13 is located at a predetermined position on the right side of the base plate 11 in front of and inside.
〈ベースプレート１１〉
　図３は、ベースプレート１１の斜視図である。ベースプレート１１は、図３に示されているように、前後方向および左右方向が予め定められている。ベースプレート１１は、略矩形のプレートである。ベースプレート１１の後側の中央部は、前方に凹んでいる。ベースプレート１１は、図１および２に示されているように、トイレ１００の前方に設置される。トイレ１００の前部は、ベースプレート１１の後側の中央部の凹んだ部位１１ａに入り込む。そして、ベースプレート１１の左右両側部の後側の部位は、トイレ１００の前部の両側に配置されうる。 <Base plate 11>
FIG. 3 is a perspective view of the base plate 11. As shown in FIG. 3, the base plate 11 is predetermined in the front-rear direction and the left-right direction. The base plate 11 is a substantially rectangular plate. The central portion on the rear side of the base plate 11 is recessed forward. The base plate 11 is installed in front of the toilet 100 as shown in FIGS. 1 and 2. The front part of the toilet 100 enters the recessed portion 11a in the central part on the rear side of the base plate 11. The rear portions of the left and right sides of the base plate 11 can be arranged on both sides of the front part of the toilet 100.
　ベースプレート１１は、例えば、鋼板やステンレス板で形成されているとよい。ベースプレート１１は、持ち運びが可能で、かつ、手すり１２，１３に利用者や介助者の体重が掛けられた際でも、容易に持ち上がらない程度の重さを有しているとよい。ベースプレート１１は、表面に化粧板が取り付けられていてもよい。また、裏面に、重量がある板が取り付けられていてもよい。 The base plate 11 may be made of, for example, a steel plate or a stainless steel plate. It is preferable that the base plate 11 is portable and has a weight that does not easily lift even when the weights of the user or the caregiver are hung on the handrails 12 and 13. The base plate 11 may have a decorative plate attached to the surface thereof. Further, a heavy plate may be attached to the back surface.
　利用者には、トイレ１００を利用する際に用いるために、手すり１２，１３をトイレ１００に近づけて設置したいとのニーズが一定程度あると想定される。ベースプレート１１は、上述のように後側の中央部の凹んだ部位１１ａを有している。手すり１２，１３をトイレ１００に近づけて設置するとの観点では、後側の中央部の凹んだ部位１１ａの両側で、ベースプレート１１の後ろ側の縁の近くに手すり１２，１３の支柱を立ててもよい。しかし、後側の中央部の凹んだ部位１１ａの両側では、ベースプレート１１の幅が細くなっている。このため、手すり１２，１３の支柱を設置する位置を、ベースプレート１１の後ろ側の縁に近づけ過ぎると、手すり１２，１３の支柱に利用者の体重が掛けられた時に、ベースプレート１１が撓む場合がある。ベースプレート１１が撓むと、手すり１２，１３が不安定になる場合がある。 It is assumed that the user has a certain degree of need to install the handrails 12 and 13 close to the toilet 100 in order to use the toilet 100. The base plate 11 has a recessed portion 11a in the central portion on the rear side as described above. From the viewpoint of installing the handrails 12 and 13 close to the toilet 100, even if the columns of the handrails 12 and 13 are erected near the rear edge of the base plate 11 on both sides of the recessed portion 11a in the central part on the rear side. good. However, the width of the base plate 11 is narrowed on both sides of the recessed portion 11a in the central portion on the rear side. For this reason, if the position where the columns of the handrails 12 and 13 are installed is too close to the rear edge of the base plate 11, the base plate 11 will bend when the user's weight is applied to the columns of the handrails 12 and 13. There is. If the base plate 11 bends, the handrails 12 and 13 may become unstable.
　ベースプレート１１の撓みを小さく抑えるとの観点では、ベースプレート１１は、全体として、所要の剛性を有しているとよい。図１に示された形態では、ベースプレート１１は、全体として平坦であるが、周縁部１１ｄが盛り上がった形状を有している。かかる形状により、ベースプレート１１の剛性が確保されている。つまり、ベースプレート１１が単純な平板である場合に比べて、ベースプレート１１が全体として撓みにくくなっている。ベースプレート１１の前側は、後側よりも、周縁部１１ｄが盛り上がる角度が緩やかである。さらに、ベースプレート１１の後ろ側の縁に近づけ過ぎず、少し前寄りに手すり１２，１３の柱３１を取り付けることとした。 From the viewpoint of suppressing the deflection of the base plate 11 to a small value, the base plate 11 should have the required rigidity as a whole. In the form shown in FIG. 1, the base plate 11 is flat as a whole, but has a shape in which the peripheral edge portion 11d is raised. Due to this shape, the rigidity of the base plate 11 is ensured. That is, the base plate 11 is less likely to bend as a whole than when the base plate 11 is a simple flat plate. On the front side of the base plate 11, the angle at which the peripheral edge portion 11d rises is gentler than that on the rear side. Further, it was decided to attach the pillars 31 of the handrails 12 and 13 slightly to the front without getting too close to the rear edge of the base plate 11.
　図示は省略するが、ベースプレート１１の平坦な部分には、マットが敷かれるとよい。マットは、ベースプレート１１の上面を概ね覆うように設けられるとよい。マットは、例えば、取り外し可能なシートやマットでもよく、いわゆる吸着マットなどを採用することができる。ベースプレート１１に鋼板材料が用いられる場合でも、マットが敷かれることによって足触りがよく、滑りにくくなり、使用感が向上する。マットは、適宜に取り外し、交換または洗濯されることによって、ベースプレート１１の表面が清潔に保たれる。 Although not shown, it is advisable to lay a mat on the flat part of the base plate 11. The mat may be provided so as to substantially cover the upper surface of the base plate 11. The mat may be, for example, a removable sheet or mat, and a so-called adsorption mat or the like can be adopted. Even when a steel plate material is used for the base plate 11, the mat is laid to make the base plate 11 feel good to the touch, less slippery, and improve the usability. The mat is appropriately removed, replaced or washed to keep the surface of the base plate 11 clean.
　ベースプレート１１には、手すり１２，１３が取り付けられる予め定められた部位に取付部１１ｂ，１１ｃが設けられている。手すり１２は、ベースプレート１１の左側に設けられている。手すり１３は、ベースプレート１１の右側に設けられている。取付部１１ｂ，１１ｃは、ベースプレート１１の左右両側部において、前後にずらした２箇所に設けられている。この実施形態では、図３に示されているように、ベースプレート１１の左右の取付部１１ｂ，１１ｃに、６つの取付孔１１ｂ１，１１ｃ１がそれぞれ形成されている。６つの取付孔１１ｂ１，１１ｃ１は、前後に長い略長方形の領域の四隅と中間位置に配置されている。６つの取付孔１１ｂ１，１１ｃ１のうち前側の４つと、後側の４つとがそれぞれ一組となって、前後にずらされた２箇所に取付部１１ｂ，１１ｃが形成されている。６つの取付孔１１ｂ１，１１ｃ１のうち中間の２つの取付孔１１ｂ１，１１ｃ１は、前後にずらされた２箇所の取付部１１ｂ，１１ｃで共通して用いられる。なお、この実施形態では、ベースプレート１１の左右両側に手すりが設けられているが、手すりは、特に言及されない限りにおいて、ベースプレート１１の左右両側のうち一方にだけ設けられていてもよい。 The base plate 11 is provided with mounting portions 11b and 11c at predetermined locations where the handrails 12 and 13 are mounted. The handrail 12 is provided on the left side of the base plate 11. The handrail 13 is provided on the right side of the base plate 11. The mounting portions 11b and 11c are provided at two locations shifted back and forth on both the left and right sides of the base plate 11. In this embodiment, as shown in FIG. 3, six mounting holes 11b1, 11c1 are formed in the left and right mounting portions 11b, 11c of the base plate 11, respectively. The six mounting holes 11b1 and 11c1 are arranged at the four corners and intermediate positions of a substantially rectangular area long in the front-rear direction. Of the six mounting holes 11b1 and 11c1, the four on the front side and the four on the rear side form a set, and the mounting portions 11b and 11c are formed at two locations shifted back and forth. Of the six mounting holes 11b1, 11c1, the two intermediate mounting holes 11b1, 11c1 are commonly used by the two mounting portions 11b, 11c displaced back and forth. In this embodiment, handrails are provided on both the left and right sides of the base plate 11, but the handrails may be provided on only one of the left and right sides of the base plate 11 unless otherwise specified.
　この実施形態では、ベースプレート１１は、周縁部１１ｄが盛り上がっている。ベースプレート１１は、周縁部１１ｄを除いて平坦な形状である。手すり１２，１３が取り付けられる取付部１１ｂ，１１ｃは、周縁部１１ｄを除いた平坦な部分に設けられている。このため、手すり１２，１３が取り付けられる取付部１１ｂ，１１ｃは、ベースプレート１１の周縁部１１ｄよりも少し内寄りに設けられている。手すり１２，１３には、内側から外側に向けて利用者の体重が掛けられる傾向がある。この実施形態では、手すり１２，１３が取り付けられる取付部１１ｂ，１１ｃが、ベースプレート１１の周縁部１１ｄよりも内側に設けられている。さらに、ベースプレート１１の周縁部１１ｄが盛り上がっている。このため、ベースプレート１１の内側から外側に向けて手すり１２，１３に利用者の体重が掛けられても、ベースプレート１１が撓みにくい。 In this embodiment, the base plate 11 has a raised peripheral portion 11d. The base plate 11 has a flat shape except for the peripheral edge portion 11d. The mounting portions 11b and 11c to which the handrails 12 and 13 are mounted are provided on a flat portion excluding the peripheral edge portion 11d. Therefore, the mounting portions 11b and 11c to which the handrails 12 and 13 are mounted are provided slightly inward from the peripheral edge portion 11d of the base plate 11. The handrails 12 and 13 tend to bear the user's weight from the inside to the outside. In this embodiment, the mounting portions 11b and 11c to which the handrails 12 and 13 are mounted are provided inside the peripheral edge portion 11d of the base plate 11. Further, the peripheral edge portion 11d of the base plate 11 is raised. Therefore, even if the user's weight is applied to the handrails 12 and 13 from the inside to the outside of the base plate 11, the base plate 11 is unlikely to bend.
〈手すり１２，１３〉
　手すり１２，１３は、図１に示されているように、柱３１と、アーム３２と、手すり部３３とを備えている。 < Handrails 12, 13>
As shown in FIG. 1, the handrails 12 and 13 include a pillar 31, an arm 32, and a handrail portion 33.
〈柱３１〉
　柱３１は、ベースプレート１１から上方に立ち上がっている。この実施形態では、柱３１は、基部３１ａと、支柱部３１ｂとを備えている。図４は、柱３１の基部３１ａの斜視図である。図５は、手すり１２の平面図である。 <Pillar 31>
The pillar 31 rises upward from the base plate 11. In this embodiment, the pillar 31 includes a base portion 31a and a pillar portion 31b. FIG. 4 is a perspective view of the base portion 31a of the pillar 31. FIG. 5 is a plan view of the handrail 12.
　基部３１ａは、図１に示されているように、ベースプレート１１に取り付けられる部位である。この実施形態では、基部３１ａは、プレート状の部材で構成されている。基部３１ａは、ベースプレート１１の上に重ねられてボルト３１ａ１で締結されている。この場合、ベースプレート１１の取付部１１ｂ，１１ｃと、手すり１２，１３の柱３１の基部３１ａとは、ベースプレート１１の上方から締結できるとよい。この実施形態では、取付部１１ｂ，１１ｃの取付孔１１ｂ１，１１ｃ１には、ナットが仕込まれている。このため、ベースプレート１１の上に基部３１ａを配置して、ボルトで締結するとよい。ベースプレート１１の取付部１１ｂ，１１ｃと、手すり１２，１３の柱３１の基部３１ａとが、ベースプレート１１の上から締結できる締結構造を有していることによって、重量のあるベースプレート１１を持ち上げて作業する必要性がなく、作業性が向上し、利用者の利便性が高くなる。 The base portion 31a is a portion attached to the base plate 11 as shown in FIG. In this embodiment, the base 31a is composed of a plate-shaped member. The base portion 31a is overlapped on the base plate 11 and fastened with bolts 31a1. In this case, it is preferable that the mounting portions 11b and 11c of the base plate 11 and the base portion 31a of the pillar 31 of the handrails 12 and 13 can be fastened from above the base plate 11. In this embodiment, nuts are installed in the mounting holes 11b1 and 11c1 of the mounting portions 11b and 11c. Therefore, it is preferable to arrange the base portion 31a on the base plate 11 and fasten it with bolts. Since the mounting portions 11b and 11c of the base plate 11 and the base portions 31a of the pillars 31 of the handrails 12 and 13 have a fastening structure that can be fastened from above the base plate 11, the heavy base plate 11 is lifted and worked. There is no need, workability is improved, and user convenience is improved.
　基部３１ａには、図４に示されているように、適宜にリブ３１ａ２が設けられていてもよい。リブ３１ａ２は、プレート状の基部３１ａが部分的に折り曲げられて形成されている。基部３１ａは、略矩形のプレートである。基部３１ａの各辺は、前後左右に向けてベースプレート１１に取り付けられる。基部３１ａの四隅には、図１に示されているように、ボルト３１ａ１が装着される。基部３１ａの四隅には、図４および図５に示されているように、ボルト３１ａ１を装着するためのボルト装着孔３１ａ３が形成されている。基部３１ａには、左右方向に沿って盛り上がった一筋の凸部が形成されている。当該凸部が、リブ３１ａ２として機能する。後述するが、この実施形態では、基部３１ａは、ベースプレート１１に対して１８０度回転させて取り付けることができる。なお、基部３１ａの構造や、基部３１ａとベースプレート１１との取付構造、基部３１ａの補強構造などは、かかる実施の形態に限定されない。 As shown in FIG. 4, the base portion 31a may be appropriately provided with ribs 31a2. The rib 31a2 is formed by partially bending a plate-shaped base portion 31a. The base 31a is a substantially rectangular plate. Each side of the base portion 31a is attached to the base plate 11 in the front-rear and left-right directions. Bolts 31a1 are mounted at the four corners of the base 31a, as shown in FIG. As shown in FIGS. 4 and 5, bolt mounting holes 31a3 for mounting bolts 31a1 are formed at the four corners of the base 31a. The base portion 31a is formed with a straight convex portion that rises along the left-right direction. The convex portion functions as the rib 31a2. As will be described later, in this embodiment, the base portion 31a can be attached by rotating the base plate 11 by 180 degrees. The structure of the base portion 31a, the mounting structure of the base portion 31a and the base plate 11, the reinforcing structure of the base portion 31a, and the like are not limited to these embodiments.
　支柱部３１ｂは、基部３１ａから上方に立ち上がった部位である。この実施形態では、支柱部３１ｂは、高さが変更可能な伸縮構造を備えている。支柱部３１ｂは、外筒６１と、内筒６２と、ボルト６３とを備えている。図６は、支柱部３１ｂの横断断面図である。図６では、支柱部３１ｂにボルト６３が装着された部位の横断面が図示されている。 The strut portion 31b is a portion that rises upward from the base portion 31a. In this embodiment, the strut portion 31b has a telescopic structure whose height can be changed. The strut portion 31b includes an outer cylinder 61, an inner cylinder 62, and a bolt 63. FIG. 6 is a cross-sectional view of the support column portion 31b. In FIG. 6, a cross section of a portion where the bolt 63 is attached to the support column portion 31b is shown.
　外筒６１は、基部３１ａに取り付けられている。図６に示されているように、外筒６１の側周面には、ボルト装着孔６１ａが形成されている。ボルト装着孔６１ａには、雌ねじ部６１ｂが設けられている。この実施形態では、雌ねじ部６１ｂとしてボルト装着孔６１ａに位置を合わせてナットが設けられている。ナットは、外筒６１に溶接されているとよい。この実施形態では、基部３１ａは、ベースプレート１１に対して１８０度回転させて取り付けることができる。外筒６１は、ボルト装着孔６１ａと雌ねじ部６１ｂとを前後にそれぞれ備えている。 The outer cylinder 61 is attached to the base 31a. As shown in FIG. 6, a bolt mounting hole 61a is formed on the side peripheral surface of the outer cylinder 61. A female screw portion 61b is provided in the bolt mounting hole 61a. In this embodiment, a nut is provided as the female screw portion 61b so as to be aligned with the bolt mounting hole 61a. The nut may be welded to the outer cylinder 61. In this embodiment, the base 31a can be rotated 180 degrees with respect to the base plate 11 and attached. The outer cylinder 61 is provided with a bolt mounting hole 61a and a female screw portion 61b in the front and rear, respectively.
　内筒６２は、外筒６１の内部に装着され、外筒６１に対して上下にスライド可能な構造を有している。内筒６２には、長さ方向に間欠的にボルト挿通孔６２ａが形成されている（図１４参照）。内筒６２は、外筒６１に対して前後に向きを変えて装着可能である。 The inner cylinder 62 is mounted inside the outer cylinder 61 and has a structure that can slide up and down with respect to the outer cylinder 61. Bolt insertion holes 62a are intermittently formed in the inner cylinder 62 in the length direction (see FIG. 14). The inner cylinder 62 can be mounted by changing its orientation in the front-rear direction with respect to the outer cylinder 61.
　ボルト６３は、図６に示されているように、外周面に雄ねじ部６３ａを有し、かつ、ボルト装着孔６１ａに設けられた雌ねじ部６１ｂに取り付けられる。ボルト６３は、外筒６１のボルト装着孔６１ａおよび内筒６２のボルト挿通孔６２ａを通じて内筒６２の内部を延びて、内筒６２の内側面に押し当たる長さを備えている。 As shown in FIG. 6, the bolt 63 has a male screw portion 63a on the outer peripheral surface and is attached to a female screw portion 61b provided in the bolt mounting hole 61a. The bolt 63 has a length that extends inside the inner cylinder 62 through the bolt mounting hole 61a of the outer cylinder 61 and the bolt insertion hole 62a of the inner cylinder 62 and presses against the inner side surface of the inner cylinder 62.
　この場合、ボルト６３が外筒６１のボルト装着孔６１ａの雌ねじ部６１ｂにねじ込まれると、図６に示されているように、ボルト６３の先端６３ｂが内筒６２の内側面に当たって、内筒６２が外筒６１に押し付けられる。これによって、内筒６２が、外筒６１に対してがたつかない。また、ボルト６３は、内筒６２から軸方向に反力を受ける。このため、ボルト装着孔６１ａの雌ねじ部６１ｂとボルト６３の雄ねじ部６３ａとの遊びがなく、摩擦力が作用する。このため、ボルト６３が緩みにくい。 In this case, when the bolt 63 is screwed into the female screw portion 61b of the bolt mounting hole 61a of the outer cylinder 61, the tip 63b of the bolt 63 hits the inner surface of the inner cylinder 62 as shown in FIG. 6, and the inner cylinder 62 Is pressed against the outer cylinder 61. As a result, the inner cylinder 62 does not rattle with respect to the outer cylinder 61. Further, the bolt 63 receives a reaction force in the axial direction from the inner cylinder 62. Therefore, there is no play between the female screw portion 61b of the bolt mounting hole 61a and the male screw portion 63a of the bolt 63, and a frictional force acts. Therefore, the bolt 63 is difficult to loosen.
　この実施形態では、ボルト６３は、図６に示されているように、雌ねじ部６１ｂに取り付けられる端部に、雄ねじ部６３ａが設けられている。また、雄ねじ部６３ａよりも先端側でボルト装着孔６１ａを通じて内筒６２の内部を延びる部分は、雌ねじ部６１ｂの内径よりも小さい。このため、ボルト６３の先端側は、雄ねじ部６３ａが設けられた部分まで、雌ねじ部６１ｂを通して内筒６２にスムーズに挿入できる。このため、ボルト６３の取り付けおよび取り外しが容易である。また、この実施形態では、ボルト６３は、雄ねじ部６３ａが設けられた端部には、さらにノブ６３ｃが設けられている。このため、工具などがなくても、ノブ６３ｃが操作されることによってボルト６３を操作できる。 In this embodiment, as shown in FIG. 6, the bolt 63 is provided with a male screw portion 63a at an end portion attached to the female screw portion 61b. Further, the portion extending inside the inner cylinder 62 through the bolt mounting hole 61a on the tip side of the male screw portion 63a is smaller than the inner diameter of the female screw portion 61b. Therefore, the tip end side of the bolt 63 can be smoothly inserted into the inner cylinder 62 through the female screw portion 61b up to the portion where the male screw portion 63a is provided. Therefore, the bolt 63 can be easily attached and detached. Further, in this embodiment, the bolt 63 is further provided with a knob 63c at the end portion where the male screw portion 63a is provided. Therefore, the bolt 63 can be operated by operating the knob 63c without using a tool or the like.
　このように、支柱部３１ｂの高さが調節され、さらには、手すり１２，１３が適当な高さに調整される。左右の手すり１２，１３は、それぞれ異なる高さに調整されてもよい。図１に示された形態では、支柱部３１ｂの上下２箇所に支柱部３１ｂの高さを調節するためのボルト６３が取り付けられる。１つのボルト６３で、支柱部３１ｂの高さを保持できる場合には、ボルト６３は支柱部３１ｂの上下１箇所に設けられていてもよい。 In this way, the height of the column portion 31b is adjusted, and further, the handrails 12 and 13 are adjusted to an appropriate height. The left and right handrails 12 and 13 may be adjusted to different heights. In the form shown in FIG. 1, bolts 63 for adjusting the height of the support column 31b are attached to the upper and lower positions of the support column 31b. If the height of the strut portion 31b can be maintained by one bolt 63, the bolt 63 may be provided at one position above and below the strut portion 31b.
　この実施形態では、支柱部３１ｂは、略矩形の基部３１ａに対して、左右幅方向の中心から片側にずらされている。例えば、図１に示された形態では、左側の手すり１２では、支柱部３１ｂがベースプレート１１の外側に配置されるように、ベースプレート１１に対して基部３１ａが取り付けられている。右側の手すり１３では、支柱部３１ｂがベースプレート１１の内側に配置されるように、ベースプレート１１に対して基部３１ａが取り付けられている。つまり、右側の手すり１３に対して、左側の手すり１２は、ベースプレート１１に基部３１ａを１８０度回転させて取り付けられている。 In this embodiment, the support column portion 31b is displaced to one side from the center in the left-right width direction with respect to the substantially rectangular base portion 31a. For example, in the form shown in FIG. 1, in the handrail 12 on the left side, the base portion 31a is attached to the base plate 11 so that the support column portion 31b is arranged outside the base plate 11. In the handrail 13 on the right side, the base portion 31a is attached to the base plate 11 so that the support column portion 31b is arranged inside the base plate 11. That is, the left handrail 12 is attached to the base plate 11 by rotating the base 31a by 180 degrees with respect to the right handrail 13.
　さらに、ベースプレート１１には、左右に６つずつ取付孔１１ｂ１，１１ｃ１が設けられている。ベースプレート１１の６つの取付孔１１ｂ１，１１ｃ１は、基部３１ａがベースプレート１１において前後２箇所にずらして取り付けられるように設けられている。この実施形態では、手すり１２，１３は、ベースプレート１１の左右において、それぞれ前後に配置が調整でき、さらにベースプレート１１に基部３１ａが１８０度回転させて取り付けられることによって、内寄りと外寄りの配置を選択できる。このため、例えば、利用者の利用しやすい位置に、手すり１２，１３が設けられる。また、手すり１２，１３は、トイレットペーパーホルダーや、シャワートイレの操作盤などをかわして配置することができる。このため、仮設手すり１０の汎用性が向上する。 Further, the base plate 11 is provided with six mounting holes 11b1 and 11c1 on each side. The six mounting holes 11b1 and 11c1 of the base plate 11 are provided so that the base portion 31a can be mounted by shifting the base plate 11 at two front and rear positions. In this embodiment, the handrails 12 and 13 can be arranged back and forth on the left and right sides of the base plate 11, and the base 31a is attached to the base plate 11 by rotating the base 31a by 180 degrees so that the handrails 12 and 13 are arranged inward and outward. You can choose. Therefore, for example, the handrails 12 and 13 are provided at positions that are easy for the user to use. Further, the handrails 12 and 13 can be arranged so as to avoid the toilet paper holder, the operation panel of the shower toilet, and the like. Therefore, the versatility of the temporary handrail 10 is improved.
　支柱部３１ｂは、図６に示されているように、長円形状（オーバル形状）を有している。支柱部３１ｂは、長円の長い幅が前後方向に向けられ、かつ、基部３１ａの中心から左右方向の一方にずらされて、基部３１ａに取り付けられている。この実施形態では、基部３１ａは、リブ３１ａ２として、左右方向に沿って盛り上がった一筋の凸部が形成されている。支柱部３１ｂは、基部３１ａのリブ３１ａ２としての凸部を跨ぐように基部３１ａに取り付けられている。 As shown in FIG. 6, the support column portion 31b has an oval shape (oval shape). The strut portion 31b is attached to the base portion 31a with the long width of the oval oriented in the front-rear direction and shifted to one side in the left-right direction from the center of the base portion 31a. In this embodiment, the base portion 31a is formed as a rib 31a2 with a straight convex portion raised along the left-right direction. The strut portion 31b is attached to the base portion 31a so as to straddle the convex portion of the base portion 31a as the rib 31a2.
　基部３１ａは、ベースプレート１１に対して１８０度回転させて取り付けることができる。そして、１８０度回転させることによって、左側の手すり１２のように、支柱部３１ｂがベースプレート１１の外側に配置されたり、右側の手すり１３のように、支柱部３１ｂがベースプレート１１の内側に配置されたりする。また、支柱部３１ｂの外筒６１には、ボルト６３を内部に挿通させるためのボルト装着孔６１ａと雌ねじ部６１ｂが、外筒６１の前後両側に設けられている。この実施形態では、内筒６２に設けられたボルト６３の軸が挿通されるためのボルト挿通孔６２ａは、内筒６２の前側の側面に形成されている。基部３１ａは、ベースプレート１１に対して１８０度回転させて取り付けられた場合には、内筒６２の前側の側面が、前側を向くように外筒６１に内筒６２が装着される。そして、外筒６１の前側のボルト装着孔６１ａと雌ねじ部６１ｂに、ボルト６３が取り付けられ、支柱部３１ｂの高さが調節される。 The base portion 31a can be attached by rotating it 180 degrees with respect to the base plate 11. Then, by rotating it 180 degrees, the strut portion 31b is arranged outside the base plate 11 like the handrail 12 on the left side, or the strut portion 31b is arranged inside the base plate 11 like the handrail 13 on the right side. do. Further, the outer cylinder 61 of the support column portion 31b is provided with bolt mounting holes 61a and female screw portions 61b for inserting the bolt 63 into the inside on both front and rear sides of the outer cylinder 61. In this embodiment, the bolt insertion hole 62a for inserting the shaft of the bolt 63 provided in the inner cylinder 62 is formed on the front side surface of the inner cylinder 62. When the base portion 31a is rotated 180 degrees with respect to the base plate 11, the inner cylinder 62 is attached to the outer cylinder 61 so that the front side surface of the inner cylinder 62 faces the front side. Then, the bolt 63 is attached to the bolt mounting hole 61a and the female screw portion 61b on the front side of the outer cylinder 61, and the height of the support column portion 31b is adjusted.
　この実施形態では、図２に示されているように、基部３１ａは、ベースプレート１１に対して１８０度回転させて取り付けることができる。外筒６１は、ボルト装着孔６１ａと雌ねじ部６１ｂとを前後にそれぞれ備えている。内筒６２は、前後方向に長いオーバル形状の外筒６１の内側よりも少し小さいオーバル形状である。内筒６２は、外筒６１に対して１８０度回転させて向きを変えて装着可能である。このため、基部を１８０度回転させても、外筒６１の前からボルト６３を装着できて内筒６２を前から固定できる。 In this embodiment, as shown in FIG. 2, the base 31a can be rotated 180 degrees with respect to the base plate 11 and attached. The outer cylinder 61 is provided with a bolt mounting hole 61a and a female screw portion 61b in the front and rear, respectively. The inner cylinder 62 has an oval shape that is slightly smaller than the inside of the outer cylinder 61 that is long in the front-rear direction. The inner cylinder 62 can be mounted by rotating it 180 degrees with respect to the outer cylinder 61 and changing its orientation. Therefore, even if the base portion is rotated 180 degrees, the bolt 63 can be attached from the front of the outer cylinder 61 and the inner cylinder 62 can be fixed from the front.
　この実施形態では、支柱部３１ｂが長円（オーバル形状）であり、ベースプレート１１の内側において支柱部３１ｂの側面が平坦である。利用者の脚が、支柱部３１ｂの内側の側面に当たっても広い面で当たる。このため、利用者の脚が支柱部３１ｂの内側に押し当たった際の圧迫感が軽減される。また、ボルト６３は、支柱部３１ｂの前側に取り付けられる。この仮設手すり１０がトイレ１００の前方に配置される。トイレ１００の便座が配置されるスペースは、横幅が限られている場合がある。また、トイレ１００の横には、洗浄装置の操作部が設けられていたり、トイレットペーパーホルダーが設置されていたりする。仮設手すり１０は、図１に示されているように、ボルト６３が常に支柱部３１ｂの前側から操作できる。このため、支柱部３１ｂの高さを変更する際のボルト６３の操作性が向上する。 In this embodiment, the strut portion 31b is an oval shape (oval shape), and the side surface of the strut portion 31b is flat inside the base plate 11. Even if the user's leg hits the inner side surface of the support column 31b, it hits a wide surface. Therefore, the feeling of oppression when the user's leg presses against the inside of the support column 31b is reduced. Further, the bolt 63 is attached to the front side of the support column portion 31b. The temporary handrail 10 is arranged in front of the toilet 100. The width of the space in which the toilet seat of the toilet 100 is arranged may be limited. Further, next to the toilet 100, an operation unit of a cleaning device may be provided, or a toilet paper holder may be installed. In the temporary handrail 10, as shown in FIG. 1, the bolt 63 can always be operated from the front side of the support column portion 31b. Therefore, the operability of the bolt 63 when changing the height of the support column portion 31b is improved.
　なお、この実施形態では、支柱部３１ｂの外形形状は、長円形状である。特に限定されない限りにおいて、支柱部３１ｂの横断面形状は、かかる形態に限定されない。支柱部３１ｂは、所要の剛性を有しているとよく、支柱部３１ｂの横断面形状は、例えば、長方形であってもよい。支柱部３１ｂの横断面形状は、デザイン性が考慮されて種々の形状が取られうる。かかる観点において、支柱部３１ｂの横断面形状は、例えば、正方形でもよいし、円形でもよい。また、支柱部３１ｂの高さを調整する構造として、支柱部３１ｂの外筒６１に対して内筒６２を固定する構造を例示した。特に言及されない限りにおいて、支柱部３１ｂの高さを調整する構造は、かかる形態に限定されない。 In this embodiment, the outer shape of the support column 31b is an oval shape. Unless otherwise limited, the cross-sectional shape of the support column 31b is not limited to such a form. The strut portion 31b may have the required rigidity, and the cross-sectional shape of the strut portion 31b may be, for example, a rectangle. As the cross-sectional shape of the support column portion 31b, various shapes can be taken in consideration of design. From this point of view, the cross-sectional shape of the support column 31b may be, for example, a square or a circle. Further, as a structure for adjusting the height of the strut portion 31b, a structure in which the inner cylinder 62 is fixed to the outer cylinder 61 of the strut portion 31b is exemplified. Unless otherwise specified, the structure for adjusting the height of the support column 31b is not limited to such a form.
〈アーム３２〉
　アーム３２は、柱３１の上端部に設けられている。アーム３２は、支柱部３１ｂの上端部から上方かつ斜め後方に延びている。図７は、アーム３２の斜視図である。図７では、アーム３２および手すり部３３を斜め後下側から見た図が図示されている。図８は、アーム３２および手すり部３３の背面図である。この実施形態では、図１に示されているように、支柱部３１ｂの内筒６２の上端に、それぞれアーム３２が取り付けられている。アーム３２は、プレートを予め定められた形状に切り出し、上面３２ａと左右両側面３２ｂ，３２ｃが形成されるように折り曲げられた部材である。アーム３２の下端は、柱３１の上端に取り付けられている。この実施形態では、アーム３２は、柱３１の上端部から上方かつ斜め後方に延びている。アーム３２の下端部は、支柱部３１ｂの内筒６２の上端に取り付けられている。この実施形態では、アーム３２の下端部は、支柱部３１ｂの内筒６２の上端に溶接されている。アーム３２の下端部には、カバー３４が装着されている。この実施形態では、アーム３２が、プレート状の部材で構成されており、軽量化と低コスト化が図られている。 <Arm 32>
The arm 32 is provided at the upper end of the pillar 31. The arm 32 extends upward and diagonally rearward from the upper end of the support column 31b. FIG. 7 is a perspective view of the arm 32. In FIG. 7, a view of the arm 32 and the handrail portion 33 as viewed from the diagonally rear lower side is shown. FIG. 8 is a rear view of the arm 32 and the handrail portion 33. In this embodiment, as shown in FIG. 1, an arm 32 is attached to the upper end of the inner cylinder 62 of the support column 31b, respectively. The arm 32 is a member obtained by cutting a plate into a predetermined shape and bending it so that an upper surface 32a and left and right side surfaces 32b and 32c are formed. The lower end of the arm 32 is attached to the upper end of the pillar 31. In this embodiment, the arm 32 extends upward and diagonally rearward from the upper end of the pillar 31. The lower end of the arm 32 is attached to the upper end of the inner cylinder 62 of the support column 31b. In this embodiment, the lower end of the arm 32 is welded to the upper end of the inner cylinder 62 of the support column 31b. A cover 34 is attached to the lower end of the arm 32. In this embodiment, the arm 32 is made of a plate-shaped member, and the weight and cost are reduced.
　柱３１の上端部（この実施形態では、アーム３２の上端部）に、手すり部３３が取り付けられる回動軸３５が取り付けられている。換言すると、手すり部３３が取り付けられる回動軸３５は、アーム３２の後端部に設けられている。回動軸３５は、左右方向に沿って延びた軸である。この実施形態では、回動軸３５は、アーム３２の左右両側面を貫通している。支柱部３１ｂの上端部から上方かつ斜め後方に延びたアーム３２の上端部に、手すり部３３の回動軸３５が設けられている。このため、手すり部３３の回動支点が柱３１に対して後側に設定できる。換言すると、手すり部３３の回動支点は、トイレ１００の座面に近い位置に設けられうる。つまり、この実施形態では、トイレ１００の前方にベースプレート１１が設置され、かつ、当該ベースプレート１１の後ろ縁から前方に離れた位置に柱３１が設置されている。それにもかかわらず、手すり部３３の回動支点が、トイレ１００の座面に近い位置に設けられる。このため手すり部３３をトイレの近い位置に配置することができる。 A rotation shaft 35 to which the handrail portion 33 is attached is attached to the upper end portion of the pillar 31 (in this embodiment, the upper end portion of the arm 32). In other words, the rotating shaft 35 to which the handrail portion 33 is attached is provided at the rear end portion of the arm 32. The rotation shaft 35 is a shaft extending in the left-right direction. In this embodiment, the rotation shaft 35 penetrates the left and right side surfaces of the arm 32. A rotation shaft 35 of the handrail portion 33 is provided at the upper end portion of the arm 32 extending upward and diagonally rearward from the upper end portion of the support column portion 31b. Therefore, the rotation fulcrum of the handrail portion 33 can be set to the rear side with respect to the pillar 31. In other words, the rotation fulcrum of the handrail portion 33 may be provided at a position close to the seat surface of the toilet 100. That is, in this embodiment, the base plate 11 is installed in front of the toilet 100, and the pillar 31 is installed at a position away from the trailing edge of the base plate 11 in front of the toilet 100. Nevertheless, the rotation fulcrum of the handrail portion 33 is provided at a position close to the seat surface of the toilet 100. Therefore, the handrail portion 33 can be arranged at a position close to the toilet.
〈手すり部３３〉
　手すり部３３は、アーム３２に設けられた回動軸３５に回動可能に取付けられている。この実施形態では、手すり部３３は、図７および図８に示されているように、骨組み３３ａと、肘掛け部材３３ｂとを備えている。骨組み３３ａは、この実施形態では、予め定められた形状に切り出されたプレート材を折り曲げた部材である。骨組み３３ａは、アーム３２の上面と左右両側面の外側に被さる、上面３３ａ１と左右両側面３３ａ２，３３ａ３とを備えている。アーム３２に設けられた回動軸３５は、骨組み３３ａの左右両側面を貫通し、骨組み３３ａを回動可能に支持している。肘掛け部材３３ｂは、骨組み３３ａの上面に取り付けられている。肘掛け部材３３ｂは、骨組み３３ａの上面に配置され、ビス３７で取り付けられている。かかる手すり部３３は、手すりおよび肘掛けとして用いられうる。このため、手すり部３３は、肘掛け部とも称されうる。肘掛け部材３３ｂは、肌触りの良い材料で構成されているとよい。肘掛け部材３３ｂは、例えば、木材や樹脂で作製されうる。 <Handrail 33>
The handrail portion 33 is rotatably attached to a rotating shaft 35 provided on the arm 32. In this embodiment, the handrail portion 33 includes a skeleton 33a and an armrest member 33b, as shown in FIGS. 7 and 8. In this embodiment, the frame 33a is a member obtained by bending a plate material cut into a predetermined shape. The skeleton 33a includes an upper surface 33a1 and left and right side surfaces 33a2 and 33a3 that cover the upper surface of the arm 32 and the outside of the left and right side surfaces. The rotation shaft 35 provided on the arm 32 penetrates the left and right side surfaces of the frame 33a and rotatably supports the frame 33a. The armrest member 33b is attached to the upper surface of the frame 33a. The armrest member 33b is arranged on the upper surface of the frame 33a and attached with a screw 37. The handrail portion 33 can be used as a handrail and an armrest. Therefore, the handrail portion 33 may also be referred to as an armrest portion. The armrest member 33b may be made of a material that is soft to the touch. The armrest member 33b can be made of, for example, wood or resin.
　図９と図１０は、それぞれ仮設手すり１０の側面図である。図９には、手すり部３３が４５度程度上方に回動した状態が示されている。図１０には、手すり部３３が１００度程度上方に回動した状態が示されている。 9 and 10 are side views of the temporary handrail 10, respectively. FIG. 9 shows a state in which the handrail portion 33 is rotated upward by about 45 degrees. FIG. 10 shows a state in which the handrail portion 33 is rotated upward by about 100 degrees.
　この実施形態では、手すり部３３は、回動軸３５を基点として回動する。手すり部３３は、図１に示されているように、前方に延びた第１ポスチャーと、図１０に示されているように、上方に延びた第２ポスチャーとを取ることができる。図９は、手すり部３３を回動させる際の中間の姿勢が示されている。手すり部３３は、当該第１ポスチャーと、第２ポスチャーとでアーム３２に支持されるとよい。当該姿勢では、手すり部３３は、回動が規制され、かつ、支持されるように構成されている。なお、第１ポスチャーと第２ポスチャーだけでなく、さらに複数の姿勢が取れるように構成されていてもよい。また、手すり部３３は、任意の角度で回動が止まるように構成されていてもよい。 In this embodiment, the handrail portion 33 rotates with the rotation shaft 35 as a base point. The handrail portion 33 can take a first posture extending forward as shown in FIG. 1 and a second posture extending upward as shown in FIG. FIG. 9 shows an intermediate posture when rotating the handrail portion 33. The handrail portion 33 may be supported by the arm 32 by the first posture and the second posture. In this posture, the handrail portion 33 is configured so that its rotation is restricted and supported. In addition to the first posture and the second posture, it may be configured to take a plurality of postures. Further, the handrail portion 33 may be configured so that the rotation stops at an arbitrary angle.
　手すり部３３は、前方に延びた第１ポスチャーで回動が維持されるロック構造を備えていてもよい。また、手すり部３３は、上方に延びた第２ポスチャーで回動が維持されるロック構造を備えていてもよい。ここで、ロック構造は、骨組み３３ａの左右両側面３３ａ２，３３ａ３を貫通するロック板３６を備えていてもよい。ロック板３６は、アーム３２の左右両側面３２ｂ，３２ｃに当り、手すり部３３の骨組み３３ａが回動するのを規制する。この実施形態では、ロック板３６は、プレート状の部材で構成されている。プレート状の部材は、視認性がよく、ロックされていることが一目瞭然となる。なお、ロック構造は、かかる形態に限定されない。例えば、ロック板３６は、プレート状でなく、軸状の部材でもよい。また、回動軸３５をラチェット式とし、所定の回動角で回転が止まるように構成されていてもよい。このようにロック構造には、公知の手法が採用されうる。 The handrail portion 33 may have a lock structure in which rotation is maintained by the first posture extending forward. Further, the handrail portion 33 may have a lock structure in which rotation is maintained by a second posture extending upward. Here, the lock structure may include a lock plate 36 that penetrates the left and right side surfaces 33a2 and 33a3 of the frame 33a. The lock plate 36 hits the left and right side surfaces 32b and 32c of the arm 32 and restricts the rotation of the frame 33a of the handrail portion 33. In this embodiment, the lock plate 36 is composed of a plate-shaped member. The plate-shaped member has good visibility and it is obvious that it is locked. The lock structure is not limited to this form. For example, the lock plate 36 may be a shaft-shaped member instead of a plate-shaped member. Further, the rotation shaft 35 may be a ratchet type and may be configured to stop the rotation at a predetermined rotation angle. As described above, a known method can be adopted for the lock structure.
　これに対して、図１に示された仮設手すり１０によれば、ベースプレート１１から上方に立ち上がった柱３１の上端部から上方かつ斜め後方にアーム３２が延びている。そして、アーム３２の上端部に設けられた回動軸３５周りに回動可能に手すり部３３が取付けられている。回動軸３５は、左右方向に沿って配置されている。手すり部３３は、アーム３２の上端部から後方に向けて上方に回動する。この仮設手すり１０では、柱３１の上端部から上方かつ斜め後方にアーム３２が延びている。このため、図１０に示されているように、手すり部３３が上方に上げられた際に、手すり部３３は、アーム３２の後端部から上方に延びた状態になる。換言すると、手すり部３３は、トイレ１００の側方において、より後方に位置する。 On the other hand, according to the temporary handrail 10 shown in FIG. 1, the arm 32 extends upward and diagonally backward from the upper end of the pillar 31 rising upward from the base plate 11. A handrail portion 33 is rotatably attached around the rotation shaft 35 provided at the upper end portion of the arm 32. The rotation shaft 35 is arranged along the left-right direction. The handrail portion 33 rotates upward from the upper end portion of the arm 32 toward the rear. In the temporary handrail 10, the arm 32 extends upward and diagonally rearward from the upper end of the pillar 31. Therefore, as shown in FIG. 10, when the handrail portion 33 is raised upward, the handrail portion 33 is in a state of extending upward from the rear end portion of the arm 32. In other words, the handrail portion 33 is located further rearward on the side of the toilet 100.
　また、ベースプレート１１から上方に立ち上がった柱３１の上端部から上方かつ斜め後方にアーム３２が延びている。そして、アーム３２の上端部に設けられた回動軸３５周りに回動可能に手すり部３３が取付けられている。このため、手すり部３３とアーム３２とが重なる部分も小さい。このため、手すり部３３の側方に設けられるカバーが小さくてよい。例えば、この実施形態では、図７および図８に示されているように、手すり部３３の骨組み３３ａの左右両側面３３ａ２，３３ａ３が下方に延び、手すり部３３とアーム３２とが重なる部分をカバーしているが、当該部分が小さくてよい。かかる左右両側面３３ａ２，３３ａ３は、手すり部３３とアーム３２とが重なる部分で指を詰めるのを防止している。なお、かかる観点で、手すり部３３とアーム３２とが重なる部分で指を詰めるのを防止するためのカバーは、手すり部３３とは別部材で設けられてもよい。 Further, the arm 32 extends upward and diagonally rearward from the upper end of the pillar 31 rising upward from the base plate 11. A handrail portion 33 is rotatably attached around the rotation shaft 35 provided at the upper end portion of the arm 32. Therefore, the portion where the handrail portion 33 and the arm 32 overlap is also small. Therefore, the cover provided on the side of the handrail portion 33 may be small. For example, in this embodiment, as shown in FIGS. 7 and 8, the left and right side surfaces 33a2 and 33a3 of the frame 33a of the handrail portion 33 extend downward to cover the portion where the handrail portion 33 and the arm 32 overlap. However, the relevant part may be small. The left and right side surfaces 33a2 and 33a3 prevent the fingers from being stuffed at the portion where the handrail portion 33 and the arm 32 overlap. From this point of view, the cover for preventing the fingers from being stuffed at the portion where the handrail portion 33 and the arm 32 overlap may be provided as a member different from the handrail portion 33.
　手すり部３３が上方に回動したときに、柱３１の上方に広い空間ができる。このため、介助が必要な場合に介助者の作業性が向上する。また、手すり部３３のサポートを必要としない利用者にとっては、手すり部３３が上方に回動されていることによって、手すり部３３が邪魔になりにくい。このように、図１に示された仮設手すり１０では、介助者や手すり部３３を必要としないトイレ１００の利用者にとって、手すり部３３が邪魔になりにくい。このため、仮設手すり１０によれば、利用者の利便性が向上する。 When the handrail portion 33 rotates upward, a wide space is created above the pillar 31. Therefore, when assistance is required, the workability of the caregiver is improved. Further, for a user who does not need the support of the handrail portion 33, the handrail portion 33 is less likely to get in the way because the handrail portion 33 is rotated upward. As described above, in the temporary handrail 10 shown in FIG. 1, the handrail portion 33 is less likely to be an obstacle for the caregiver and the user of the toilet 100 who does not need the handrail portion 33. Therefore, according to the temporary handrail 10, the convenience of the user is improved.
　また、回動軸３５が、アーム３２の上端部に設けられている。回動軸３５は、手すり部３３の後側（ぼぼ後端に近い位置）に設けられている。このため、手すり部３３は、前端が持ち上げられることによって、大きく跳ね上げられる。また、平面視において、柱３１は、手すり部３３の中間部に位置している。アーム３２が、柱３１の上端部から上方かつ斜め後方に延びているため、手すり部３３の回動支点は、手すり部３３の後端部に設けられている。このため、利用者が手すり部３３の回動支点よりも後方に体重を掛けても、手すり部３３が不用意に回動しにくい。また、手すり部３３にはロック構造も設けられており、手すり部３３が不用意に後方に回動することは防止される。 Further, the rotation shaft 35 is provided at the upper end portion of the arm 32. The rotating shaft 35 is provided on the rear side of the handrail portion 33 (at a position close to the rear end of the bob). Therefore, the handrail portion 33 is greatly flipped up by the front end being lifted. Further, in a plan view, the pillar 31 is located in the middle portion of the handrail portion 33. Since the arm 32 extends upward and diagonally rearward from the upper end portion of the pillar 31, the rotation fulcrum of the handrail portion 33 is provided at the rear end portion of the handrail portion 33. Therefore, even if the user puts his / her weight behind the rotation fulcrum of the handrail portion 33, the handrail portion 33 is unlikely to rotate carelessly. Further, the handrail portion 33 is also provided with a lock structure to prevent the handrail portion 33 from inadvertently rotating backward.
　なお、この実施形態では、回動軸３５は、左右方向に沿って延びている。この場合、手すり部３３は前後方向に動き、手すり部３３の可動域は左右方向に広がらない。このため、仮設手すり１０は、省スペースに設置しやすい。なお、特に言及されない場合において、回動軸３５は、左右方向に完全に沿って配置されている必要はなく、左右方向に対して傾いていてもよい。例えば、手すり部３３の可動域が広がることが許容されるような場合には、回動軸３５は、左右方向に対して傾いていてもよい。 In this embodiment, the rotation shaft 35 extends in the left-right direction. In this case, the handrail portion 33 moves in the front-rear direction, and the range of motion of the handrail portion 33 does not widen in the left-right direction. Therefore, the temporary handrail 10 can be easily installed in a small space. Unless otherwise specified, the rotation shaft 35 does not have to be arranged completely along the left-right direction, and may be tilted with respect to the left-right direction. For example, if the range of motion of the handrail portion 33 is allowed to be widened, the rotation shaft 35 may be tilted with respect to the left-right direction.
　図１１は、仮設手すり１０の変形例を示す縦断側面図である。図１１に示されているように、アーム３２には、内側に補強構造を備えていてもよい。図１１に示された形態では、折り曲げられたプレート片４１がアーム３２の左右両側面３２ｂ，３２ｃの間に取り付けられている（図７および図８参照）。プレート片４１は、アーム３２の左右両側面３２ｂ，３２ｃにそれぞれ溶接されているとよい。また、アーム３２の上面３２ａの上に、手すり部３３の基端部を支持する台座４２が設けられている。台座４２の上端４２ａは平坦になっており、手すり部３３の骨組み３３ａの下面３３ａ１を支持する。台座４２は、プレート材で設けられており、一部がアーム３２の内部に貫通するように取り付けられているとよい。手すり部３３の骨組み３３ａの左右両側面３３ａ２，３３ａ３は、台座４２の両側を覆っているとよい。また、この実施形態では、台座４２の後端部４２ｂは、回動軸３５の後ろ側を覆っている。これにより、アーム３２の回動軸３５の後ろ側の隙間から指などが入る事象が防がれる。このように、アーム３２の回動軸３５の後ろ側の隙間にカバーが設けられていてもよい。 FIG. 11 is a vertical sectional side view showing a modified example of the temporary handrail 10. As shown in FIG. 11, the arm 32 may be provided with a reinforcing structure inside. In the form shown in FIG. 11, the bent plate piece 41 is attached between the left and right side surfaces 32b and 32c of the arm 32 (see FIGS. 7 and 8). The plate piece 41 may be welded to the left and right side surfaces 32b and 32c of the arm 32, respectively. Further, a pedestal 42 for supporting the base end portion of the handrail portion 33 is provided on the upper surface 32a of the arm 32. The upper end 42a of the pedestal 42 is flat and supports the lower surface 33a1 of the frame 33a of the handrail portion 33. The pedestal 42 is provided with a plate material, and it is preferable that the pedestal 42 is attached so as to partially penetrate the inside of the arm 32. The left and right side surfaces 33a2 and 33a3 of the frame 33a of the handrail portion 33 may cover both sides of the pedestal 42. Further, in this embodiment, the rear end portion 42b of the pedestal 42 covers the rear side of the rotating shaft 35. This prevents a finger or the like from entering through a gap on the rear side of the rotation shaft 35 of the arm 32. In this way, a cover may be provided in the gap on the rear side of the rotation shaft 35 of the arm 32.
　図１２は、仮設手すり１０の変形例を示す側面図である。図１２に示されているように、柱３１の上部には、手が添えられたときに掴みやすいように、把手４３が取り付けられていてもよい。把手４３は、例えば、ゴムのように柔らかい材料で形成されているとよい。把手４３の形状は、種々変更されうる。 FIG. 12 is a side view showing a modified example of the temporary handrail 10. As shown in FIG. 12, a handle 43 may be attached to the upper part of the pillar 31 so that it can be easily grasped when a hand is attached. The handle 43 may be made of a soft material such as rubber. The shape of the handle 43 can be changed in various ways.
　図１３と図１４は、それぞれ柱３１の変形例を示す側面図である。図１３に示されているように、内筒６２に形成されるボルト挿通孔６２ａは、内筒６２が上下に昇降調整可能な範囲において、外筒６１内に収められる範囲に設けられていてもよい。これにより、ボルト挿通孔６２ａが、外筒６１の外に出ないので、ボルト挿通孔６２ａに物が引っ掛かるなどの事象が生じない。外筒６１に設けられるボルト装着孔６１ａは、図１３に示されているように、外筒６１の高さの半分よりも上に、１つ設けられていてもよい。ボルト装着孔６１ａが外筒６１の高さの半分よりも上に設けられていることによって、内筒６２のスライド量を大きく取ることができる。また、内筒６２に形成されたボルト挿通孔６２ａが外筒６１から露出しない程度にスライド量を制限した場合は、内筒６２のうち外筒６１に収容された部分が長く確保される。このため、がたつきが小さく抑えられる。 13 and 14 are side views showing a modified example of the pillar 31, respectively. As shown in FIG. 13, even if the bolt insertion hole 62a formed in the inner cylinder 62 is provided in a range that can be accommodated in the outer cylinder 61 within a range in which the inner cylinder 62 can be vertically adjusted up and down. good. As a result, the bolt insertion hole 62a does not go out of the outer cylinder 61, so that an event such as an object being caught in the bolt insertion hole 62a does not occur. As shown in FIG. 13, one bolt mounting hole 61a provided in the outer cylinder 61 may be provided above half the height of the outer cylinder 61. Since the bolt mounting hole 61a is provided above half the height of the outer cylinder 61, the slide amount of the inner cylinder 62 can be increased. Further, when the slide amount is limited to the extent that the bolt insertion hole 62a formed in the inner cylinder 62 is not exposed from the outer cylinder 61, the portion of the inner cylinder 62 housed in the outer cylinder 61 is secured for a long time. Therefore, rattling can be suppressed to a small extent.
　かかる形態に限定されず、外筒６１に設けられるボルト装着孔６１ａは、外筒６１の高さの半分よりも下に設けられていてもよい。また、他の形態として、柱３１の外筒６１には、図１４に示されているように、上下２箇所にボルト６３が取り付けられてもよい。これにより、内筒６２が安定する。また、柱３１の基部３１ａは、１８０度回転させて、ベースプレート１１に取り付けられる。このため、外筒６１に対して、内筒６２は、１８０度回転させて装着できるように構成されていてもよい。この実施形態では、図１に示されているように、内筒６２の外側面に印６２ｂが設けられている。当該印６２ｂは、外筒６１の上端に合わせられることによって、内筒６２のボルト挿通孔６２ａと外筒６１のボルト装着孔６１ａとの位置が合うように設けられているとよい。かかる印６２ｂは、ノッチやシールや塗料などでマーキングされているとよい。印６２ｂは、例えば、内筒６２の前側の外側面に設けられているとよい。 The bolt mounting hole 61a provided in the outer cylinder 61 may be provided below half the height of the outer cylinder 61 without being limited to such a form. Further, as another form, bolts 63 may be attached to the outer cylinder 61 of the pillar 31 at two upper and lower positions as shown in FIG. This stabilizes the inner cylinder 62. Further, the base portion 31a of the pillar 31 is rotated 180 degrees and attached to the base plate 11. Therefore, the inner cylinder 62 may be configured to be mounted by being rotated 180 degrees with respect to the outer cylinder 61. In this embodiment, as shown in FIG. 1, a mark 62b is provided on the outer surface of the inner cylinder 62. It is preferable that the mark 62b is provided so that the bolt insertion hole 62a of the inner cylinder 62 and the bolt mounting hole 61a of the outer cylinder 61 are aligned by aligning with the upper end of the outer cylinder 61. The mark 62b may be marked with a notch, a seal, a paint, or the like. The mark 62b may be provided on the outer surface on the front side of the inner cylinder 62, for example.
　仮設手すり１０の手すり１２，１３は、図１に示されているように、ベースプレート１１の取付部１１ｂ，１１ｃに取付けられる基部３１ａと、基部３１ａから立ち上がった支柱部３１ｂと、支柱部３１ｂの上端部に設けられた手すり部３３とを備えている。この実施形態では、支柱部３１ｂの上端部にアーム３２が設けられており、当該アーム３２に手すり部３３が設けられている。図２に示されているように、手すり部３３は、平面視において、基部３１ａの予め定められた中心位置に対して偏心した位置に設けられている。基部３１ａとベースプレート１１とは、基部３１ａが、ベースプレート１１に対して予め定められた取り付け中心位置に対して回転させた複数の状態でベースプレート１１に取付けられる取付構造を有している。 As shown in FIG. 1, the handrails 12 and 13 of the temporary handrail 10 have a base portion 31a attached to the mounting portions 11b and 11c of the base plate 11, a strut portion 31b rising from the base portion 31a, and an upper end of the strut portion 31b. It is provided with a handrail portion 33 provided in the portion. In this embodiment, an arm 32 is provided at the upper end portion of the support column portion 31b, and a handrail portion 33 is provided on the arm 32. As shown in FIG. 2, the handrail portion 33 is provided at a position eccentric with respect to a predetermined center position of the base portion 31a in a plan view. The base portion 31a and the base plate 11 have a mounting structure in which the base portion 31a is mounted on the base plate 11 in a plurality of states rotated with respect to a predetermined mounting center position with respect to the base plate 11.
　この実施形態では、基部３１ａは、１８０度回転させてベースプレート１１に取り付けることができる。例えば、図２において、左側に配置された手すり１２は、手すり部３３がベースプレート１１に対して外寄り、言い換えると左側の基部３１ａを基準にしてベースプレート１１の外寄りである。これに対して、右側に配置された手すり１３は、手すり部３３がベースプレート１１に対して内寄り、言い換えると右側の基部３１３１ａを基準にしてベースプレート１１の内寄りである。左側に配置された手すり１２の基部３１ａを１８０度回転させてベースプレート１１に取り付けることによって、手すり１２，１３の手すり部３３を、両方とも内寄りにすることができる。右側に配置された手すり１３の基部３１ａを１８０度回転させてベースプレート１１に取り付けることによって、手すり１２，１３の手すり部３３を、両方とも外寄りにすることができる。このように、基部３１ａを１８０度回転させて取り付けることによって、ベースプレート１１に対して手すり部３３の位置が変更される。この実施形態では、基部３１ａに形成されたボルト装着孔３１ａ３と、ベースプレート１１に設けられた取付孔１１ｂ１，１１ｃ１との関係において、ベースプレート１１に対して基部３１ａが取り付けられる中心位置が定められる。このように基部３１ａがベースプレート１１に対して取り付けられる取り付け中心位置は、ベースプレート１１と基部３１ａの取付構造によって定められうる。 In this embodiment, the base 31a can be rotated 180 degrees and attached to the base plate 11. For example, in FIG. 2, in the handrail 12 arranged on the left side, the handrail portion 33 is outward to the base plate 11, in other words, the handrail portion 11 is outward to the base plate 11 with reference to the left base portion 31a. On the other hand, in the handrail 13 arranged on the right side, the handrail portion 33 is inward with respect to the base plate 11, in other words, the handrail portion 13 is inward with reference to the base portion 3131a on the right side. By rotating the base 31a of the handrail 12 arranged on the left side by 180 degrees and attaching it to the base plate 11, the handrail portions 33 of the handrails 12 and 13 can both be inward. By rotating the base 31a of the handrail 13 arranged on the right side by 180 degrees and attaching it to the base plate 11, both the handrail portions 33 of the handrails 12 and 13 can be made outward. By rotating the base portion 31a by 180 degrees and attaching the base portion 31a in this way, the position of the handrail portion 33 is changed with respect to the base plate 11. In this embodiment, in relation to the bolt mounting holes 31a3 formed in the base portion 31a and the mounting holes 11b1 and 11c1 provided in the base plate 11, the center position where the base portion 31a is mounted is determined with respect to the base plate 11. The mounting center position where the base portion 31a is mounted with respect to the base plate 11 in this way can be determined by the mounting structure of the base plate 11 and the base portion 31a.
　図１５と図１６は、それぞれアーム３２の変形例を示す平面図である。アーム３２は、柱３１の上端部において、支柱部３１ｂの上端部から上方かつ斜め後方に延びているとよい。例えば、図１に示されているように、アーム３２は、支柱部３１ｂの上端部から真っ直ぐ後方に延びていてもよい。また、アーム３２は、図１５または図１６に示されているように、支柱部３１ｂの上端部から左右方向に斜め後方に延びていてもよい。アーム３２は、支柱部３１ｂの上端部から左右方向に傾けつつ後方に延びている場合、例えば、支柱部３１ｂの上端部に対して、アーム３２を１８０度回転させて取り付けられるようにしてもよい。柱３１の基部３１ａは、１８０度回転させて、ベースプレート１１に取り付けられる。これに合わせて、アーム３２を適宜に１８０度回転させることによって、図１５と図１６に示されるように、柱３１に対して、内寄りまたは外寄りに手すり部３３が設けられる位置を調整することができる。このように、柱３１の上端部において、アーム３２が延びる向きが変更可能であってもよい。この場合、柱３１の上端部において、回転方向と上下方向に向きが変えられる自在継手を介してアーム３２が取り付けられていてもよい。回転方向と上下方向に向きが変えられる自在継手は、公知のヒンジ構造が適用できる。 15 and 16 are plan views showing a modified example of the arm 32, respectively. The arm 32 may extend upward and diagonally rearward from the upper end of the pillar 31b at the upper end of the pillar 31. For example, as shown in FIG. 1, the arm 32 may extend straight rearward from the upper end of the strut 31b. Further, as shown in FIG. 15 or 16, the arm 32 may extend diagonally rearward in the left-right direction from the upper end portion of the support column portion 31b. When the arm 32 extends rearward while tilting left and right from the upper end portion of the support column portion 31b, for example, the arm 32 may be attached by rotating the arm 32 by 180 degrees with respect to the upper end portion of the support column portion 31b. .. The base portion 31a of the pillar 31 is rotated 180 degrees and attached to the base plate 11. In accordance with this, by appropriately rotating the arm 32 by 180 degrees, the position where the handrail portion 33 is provided inward or outward with respect to the pillar 31 is adjusted as shown in FIGS. 15 and 16. be able to. In this way, the direction in which the arm 32 extends may be changeable at the upper end of the pillar 31. In this case, the arm 32 may be attached to the upper end of the pillar 31 via a universal joint whose direction can be changed in the rotation direction and the vertical direction. A known hinge structure can be applied to a universal joint whose direction can be changed in the rotation direction and the vertical direction.
　なお、上述した実施形態では、柱３１の上端部にアーム３２が設けられており、当該アーム３２の上端部に手すり部３３が取り付けられている。仮設手すりは、かかる形態に限定されない。例えば、柱３１の上端部には、アーム３２がなくてもよい。また、上述した実施形態では、手すり部３３は、柱３１の上端部において、前方に延びた第１ポスチャーと、上方に延びた第２ポスチャーとを取ることができる。つまり、手すり部３３は、柱３１の上端部に設けられた回動軸３５に取り付けられており、手すり部３３が後方に跳ね上げられる。ここで開示される仮設手すりは、かかる形態に限定されない。手すり部３３は、柱３１の上端部に固定されていてもよい。この場合、手すり部３３を跳ね上げることはできないが、仮設手すりは、安価に構成されうる。また、アーム３２を設けずに、柱３１の上端部に手すり部３３を直接取り付ける場合も安価に構成されうる。 In the above-described embodiment, the arm 32 is provided at the upper end of the pillar 31, and the handrail portion 33 is attached to the upper end of the arm 32. The temporary handrail is not limited to such a form. For example, the arm 32 may not be provided at the upper end of the pillar 31. Further, in the above-described embodiment, the handrail portion 33 can take a first posture extending forward and a second posture extending upward at the upper end portion of the pillar 31. That is, the handrail portion 33 is attached to the rotation shaft 35 provided at the upper end portion of the pillar 31, and the handrail portion 33 is flipped up rearward. The temporary handrail disclosed here is not limited to such a form. The handrail portion 33 may be fixed to the upper end portion of the pillar 31. In this case, the handrail portion 33 cannot be flipped up, but the temporary handrail can be constructed at low cost. Further, when the handrail portion 33 is directly attached to the upper end portion of the pillar 31 without providing the arm 32, it can be constructed at low cost.
　図１７は、柱３１および手すり部３３の変形例を示す側面図である。図１７には、柱３１の上端部にアーム３２がなく、手すり部３３が、柱３１の上端部に直接固定された手すり１２が示されている。図１７に示された形態では、手すり部３３は、支持部材３３ｃと、肘木３３ｄとを備えている。支持部材３３ｃは、金属性のブラケットであり、所要の機械強度を備えている。この実施形態では、支持部材３３ｃは、長片状の部材である。長さ方向の中間部３３ｃ１が柱３１の上端部に溶接されている。支持部材３３ｃは、例えば、幅方向の両側がそれぞれ下側に折り曲げられている。柱３１の上端部に溶接された支持部材３３ｃの溶接部３３ｃ１では、下側に折り曲げられた幅方向の両側が柱３１の上端部を挟み、幅方向の両側がそれぞれ柱３１の上端部にそれぞれ溶接されているとよい。肘木３３ｄは、支持部材３３ｃの上辺にねじによって固定されているとよい。 FIG. 17 is a side view showing a modified example of the pillar 31 and the handrail portion 33. FIG. 17 shows a handrail 12 in which the handrail portion 33 is directly fixed to the upper end portion of the pillar 31 without the arm 32 at the upper end portion of the pillar 31. In the form shown in FIG. 17, the handrail portion 33 includes a support member 33c and an elbow tree 33d. The support member 33c is a metallic bracket and has a required mechanical strength. In this embodiment, the support member 33c is a strip-shaped member. The intermediate portion 33c1 in the length direction is welded to the upper end portion of the column 31. The support member 33c is bent downward on both sides in the width direction, for example. In the welded portion 33c1 of the support member 33c welded to the upper end portion of the pillar 31, both sides in the width direction bent downward sandwich the upper end portion of the pillar 31, and both sides in the width direction are respectively on the upper end portion of the pillar 31. It should be welded. The elbow tree 33d may be fixed to the upper side of the support member 33c by a screw.
　また、図１７に示された形態では、柱３１は、外筒６１と内筒６２とを備え、ボルト６３によって高さ調整できるように構成されている。ボルト６３の取付構造は、上述したとおりである。なお、柱３１は、高さを調整できるように構成されているが、高さを調整できないものでもよい。この場合、柱３１は、中空の軸部材で、予め定められた所要の長さを備えていてもよい。このように、ここで開示される仮設手すり１０には、特に言及されない場合、柱３１は、高さを調整できないものでもよい。 Further, in the form shown in FIG. 17, the pillar 31 includes an outer cylinder 61 and an inner cylinder 62, and is configured so that the height can be adjusted by a bolt 63. The mounting structure of the bolt 63 is as described above. The pillar 31 is configured so that the height can be adjusted, but the height may not be adjustable. In this case, the pillar 31 is a hollow shaft member and may have a predetermined required length. As described above, unless otherwise specified, the temporary handrail 10 disclosed here may have the height of the pillar 31 whose height cannot be adjusted.
　また、図１に示された形態では、柱３１の基部３１ａは、プレート状であり、ボルト装着孔３１ａ３（図４参照）を有している。ベースプレート１１は、基部３１ａのボルト装着孔３１ａ３に対応した取付孔１１ｂ１，１１ｃ１を有している（図３参照）。取付孔１１ｂ１，１１ｃ１にはナットを有している。このため、ベースプレート１１に柱３１を取り付ける際に、ベースプレート１１を設置した状態で、ベースプレート１１の上に柱３１を配置して、ボルトで固定することができる。上述したように仮設手すり１０のベースプレート１１は、容易に浮き上がらないように所要の重さを有している。柱３１を取り付ける際に、ベースプレート１１を持ち上げる必要がないので、柱３１をベースプレート１１に取り付ける際の作業性が格段に向上する。 Further, in the form shown in FIG. 1, the base portion 31a of the pillar 31 is plate-shaped and has a bolt mounting hole 31a3 (see FIG. 4). The base plate 11 has mounting holes 11b1 and 11c1 corresponding to the bolt mounting holes 31a3 of the base portion 31a (see FIG. 3). The mounting holes 11b1 and 11c1 have nuts. Therefore, when the pillar 31 is attached to the base plate 11, the pillar 31 can be arranged on the base plate 11 with the base plate 11 installed and fixed with bolts. As described above, the base plate 11 of the temporary handrail 10 has a required weight so as not to be easily lifted. Since it is not necessary to lift the base plate 11 when the pillar 31 is attached, the workability when attaching the pillar 31 to the base plate 11 is significantly improved.
　図１に示された形態では、ボルト装着孔３１ａ３は、基部３１ａの周縁部に形成されている。このため、プレート状をベースプレート１１に強固に取り付けることができる。基部３１ａは、盛り上がった一筋の凸部３１ａ２を有している。かかる盛り上がった一筋の凸部３１ａ２は、上述したようにリブとして機能する。かかる凸部３１ａ２が設けられていることによって、プレート状の基部３１ａの剛性が高くなる。さらに、支柱部３１ｂは、基部３１ａの凸部３１ａ２を跨ぐように取り付けられている。 In the form shown in FIG. 1, the bolt mounting hole 31a3 is formed on the peripheral edge of the base 31a. Therefore, the plate shape can be firmly attached to the base plate 11. The base portion 31a has a raised straight line of convex portions 31a2. The raised straight convex portion 31a2 functions as a rib as described above. By providing the convex portion 31a2, the rigidity of the plate-shaped base portion 31a is increased. Further, the support column portion 31b is attached so as to straddle the convex portion 31a2 of the base portion 31a.
　支柱部３１ｂは、略矩形の基部３１ａに対して、左右幅方向の中心から片側にずらされた位置に設けられており、基部３１ａは、ベースプレート１１に対して１８０度回転させて取り付けることができる。基部３１ａに柱３１を設ける位置は、かかる形態に限定されない。 The support column portion 31b is provided at a position shifted to one side from the center in the left-right width direction with respect to the substantially rectangular base portion 31a, and the base portion 31a can be attached by rotating it 180 degrees with respect to the base plate 11. .. The position where the pillar 31 is provided on the base portion 31a is not limited to such a form.
　図１８は、基部３１ａを覆うカバー５０を示す斜視図である。仮設手すり１０は、図１８に示されているように、支柱部３１ｂの周りで基部３１ａを覆うカバー５０を有していてもよい。この実施形態では、カバー５０は、支柱部３１ｂが挿通される開口５１と、開口５１に通じるスリット５２とを有している。また、カバー５０は、基部３１ａに設けられたリブ３１ａ２に応じた形状を有している。開口５１は、支柱部３１ｂの形状に合わせてオーバル形状（長円）であり、前後方向の幅が長く、左右方向の幅が短い。また、開口５１の縁５１ａは、盛り上がっている。スリット５２は、開口５１の前後に設けられた半円部分の先端から周縁部に至るように形成されている。また、カバー５０は、所要の剛性と可撓性を有する樹脂製であり、カバー５０の裏面には、形状を維持するためのリブが適宜に設けられている。このカバー５０は、弾性範囲内でスリット５２を広げることができる。そして、広げられたスリット５２の隙間から開口５１に支柱部３１ｂを挿し込めるようになっている。このため、支柱部３１ｂに手すり部３３が取り付けられた後であっても、基部３１ａにカバー５０を取り付けたり、取り外したりすることができる。 FIG. 18 is a perspective view showing a cover 50 covering the base 31a. The temporary handrail 10 may have a cover 50 that covers the base portion 31a around the strut portion 31b, as shown in FIG. In this embodiment, the cover 50 has an opening 51 through which the support column 31b is inserted and a slit 52 leading to the opening 51. Further, the cover 50 has a shape corresponding to the rib 31a2 provided on the base portion 31a. The opening 51 has an oval shape (oval) that matches the shape of the support column portion 31b, and has a long width in the front-rear direction and a short width in the left-right direction. Further, the edge 51a of the opening 51 is raised. The slit 52 is formed so as to extend from the tip of the semicircular portion provided before and after the opening 51 to the peripheral edge portion. Further, the cover 50 is made of a resin having the required rigidity and flexibility, and ribs for maintaining the shape are appropriately provided on the back surface of the cover 50. The cover 50 can widen the slit 52 within the elastic range. Then, the support column portion 31b can be inserted into the opening 51 through the gap of the widened slit 52. Therefore, the cover 50 can be attached to or removed from the base portion 31a even after the handrail portion 33 is attached to the support column portion 31b.
　図１９は、柱３１の基部３１ａの変形例を模式的に示す平面図である。図１９に示されているように、基部３１ａは、正方形として四隅にボルト装着孔３１ａ３が設けられていてもよい。ベースプレート１１には、基部３１ａのボルト装着孔３１ａ３に対応して取付孔１１ｂ１，１１ｃ１が形成されているとよい。この場合、基部３１ａは、ベースプレート１１に対して９０度回転させて取り付けられうる。支柱部３１ｂは、ベースプレート１１に対して取り付けられる際の基部３１ａの回転中心位置からずらした位置に設けられうる。図１９に示された形態では、支柱部３１ｂは、基部３１ａの回転中心位置から対角線に沿ってずらされた位置に設けられている。この場合、ベースプレート１１に基部３１ａを取り付ける位置が同じでも、基部３１ａをベースプレート１１に対して回転させることで、ベースプレート１１に対する支柱部３１ｂの位置を４通りに調整することができる。さらに、図１～図３に示された形態のように、ベースプレート１１の左右両側にそれぞれ前後にずらした２箇所に基部３１ａの取り付け位置が設けられている場合には、ベースプレート１１の左右両側において、支柱部３１ｂの位置がそれぞれ８通りに用意される。これにより、ベースプレート１１に対して支柱部３１ｂの位置および手すり部３３の位置を微調整しやすくなる。 FIG. 19 is a plan view schematically showing a modified example of the base portion 31a of the pillar 31. As shown in FIG. 19, the base 31a may be square and may be provided with bolt mounting holes 31a3 at four corners. It is preferable that the base plate 11 is formed with mounting holes 11b1 and 11c1 corresponding to the bolt mounting holes 31a3 of the base portion 31a. In this case, the base 31a can be attached by rotating it 90 degrees with respect to the base plate 11. The strut portion 31b may be provided at a position deviated from the rotation center position of the base portion 31a when it is attached to the base plate 11. In the form shown in FIG. 19, the support column portion 31b is provided at a position shifted diagonally from the rotation center position of the base portion 31a. In this case, even if the position where the base 31a is attached to the base plate 11 is the same, the position of the support column 31b with respect to the base plate 11 can be adjusted in four ways by rotating the base 31a with respect to the base plate 11. Further, as in the form shown in FIGS. 1 to 3, when the mounting positions of the base 31a are provided at two locations shifted back and forth on the left and right sides of the base plate 11, the left and right sides of the base plate 11 , The positions of the support columns 31b are prepared in eight ways. This facilitates fine adjustment of the position of the support column portion 31b and the position of the handrail portion 33 with respect to the base plate 11.
　このように、基部は、ベースプレートに対して取り付けられる向きは、ベースプレートに対する取り付け中心位置に対して、２以上設けられるとよい。例えば、図示は省略するが、基部は、三角形や五角形や六角形などとしてもよい。さらに基部は、円盤形状でもよい。そして、基部は、その形状に応じて複数の回転した向きでベースプレートに取り付けられるように構成されていてもよい。これにより、ベースプレート１１に対して支柱部３１ｂの位置および手すり部３３の位置を微調整しやすくなる。このため、狭いトイレスペースであっても、利用者の都合や設備に応じて、支柱部３１ｂの位置および手すり部３３の位置を適切に調整できる。 As described above, it is preferable that the base is provided with two or more orientations with respect to the base plate with respect to the mounting center position with respect to the base plate. For example, although not shown, the base may be a triangle, a pentagon, a hexagon, or the like. Further, the base may have a disk shape. The base may be configured to be attached to the base plate in a plurality of rotational orientations depending on its shape. This facilitates fine adjustment of the position of the support column portion 31b and the position of the handrail portion 33 with respect to the base plate 11. Therefore, even in a narrow toilet space, the position of the support column 31b and the position of the handrail portion 33 can be appropriately adjusted according to the convenience and equipment of the user.
