Description

調整式レールブラケット及びこれを備えたエレベータ装置Adjustable rail bracket and elevator equipment with it
　本発明は、調整式レールブラケット及びこれを備えたエレベータ装置に関する。 The present invention relates to an adjustable rail bracket and an elevator device provided with the adjustable rail bracket.
　エレベータのガイドレールブラケットの従来技術として、例えば特許文献１がある。特許文献１には、Ｌ字形状の壁側ブラケットとＬ字形状のレール側ブラケットとを用いて、エレベータのガイドレールを壁に固定している。壁側ブラケットはＬ字状に形成され、垂直片にアンカーボルト通して壁に固定する。レール側ブラケットはＬ字状に形成され、垂直片にガイドレールが固定される。壁側ブラケットの水平片には左右方向に延びた長穴を形成され、レール側ブラケットの水平片には奥行方向に延びた長穴が形成されている。壁側ブラケットとレール側ブラケットとの接合にあたっては、それぞれの長穴の位置を合わせた状態でボルトを挿入する。そして、ガイドレールは、壁側ブラケットとレール側ブラケットのそれぞれの水平片に形成された長穴を利用して、左右方向及び奥行方向の位置が調整される。 For example, Patent Document 1 is a conventional technique for an elevator guide rail bracket. In Patent Document 1, an elevator guide rail is fixed to a wall by using an L-shaped wall-side bracket and an L-shaped rail-side bracket. The wall-side bracket is formed in an L shape, and is fixed to the wall by passing anchor bolts through a vertical piece. The rail-side bracket is formed in an L shape, and the guide rail is fixed to the vertical piece. The horizontal piece of the wall side bracket is formed with an elongated hole extending in the left-right direction, and the horizontal piece of the rail side bracket is formed with an elongated hole extending in the depth direction. When joining the wall side bracket and the rail side bracket, insert the bolts with the respective slotted holes aligned. Then, the positions of the guide rail in the left-right direction and the depth direction are adjusted by utilizing the elongated holes formed in the horizontal pieces of the wall-side bracket and the rail-side bracket.
　また、地震動による水平荷重に対する耐力を向上させるために、壁側ブラケットとレール側ブラケットの水平片の何れか一方には凹凸面部を形成すると共に、この凹凸面部に接着剤を塗布して壁側ブラケットとレール側ブラケットの水平片を接合するようにしている。 Further, in order to improve the proof stress against the horizontal load due to the earthquake motion, an uneven surface portion is formed on either one of the horizontal pieces of the wall side bracket and the rail side bracket, and an adhesive is applied to the uneven surface portion to apply the adhesive to the wall side bracket. And the horizontal piece of the rail side bracket are joined.

　図２は本発明の実施例に係る壁側ブラケットとレール側ブラケットの上面図、図３は本発明の実施例に係るエレベータ調整式レールブラケットを示す上面図、図４は図３に示したエレベータ調整式レールブラケットの側面図である。なお、上面図とはエレベータが設置される昇降路内において上方向から下方向に向かって見た状態のものである。 FIG. 2 is a top view of the wall-side bracket and the rail-side bracket according to the embodiment of the present invention, FIG. 3 is a top view showing the elevator adjustable rail bracket according to the embodiment of the present invention, and FIG. 4 is the elevator shown in FIG. It is a side view of the adjustable rail bracket. The top view is a view from the top to the bottom in the hoistway where the elevator is installed.
　ここでエレベータ調整式レールブラケットは、ガイドレール２Ａを固定したものとして説明するが、他のガイドレール２Ｂ，４Ａ，４Ｂを固定するエレベータ調整式レールブラケットについても同様である。 Here, the elevator adjustable rail bracket will be described assuming that the guide rail 2A is fixed, but the same applies to the elevator adjustable rail bracket that fixes the other guide rails 2B, 4A, 4B.
　壁側ブラケット１１は、昇降路の壁面１２に沿って配置された基部１１Ａと、この基部１１Ａに対してほぼ直角に折り曲げられてほぼ水平に配置された水平部１１Ｂを有している。壁側ブラケット１１は側面から見た形状が、Ｌ字状に形成されている。また壁側ブラケット１１は、水平部１１Ｂに対し、基部１１Ａが下方に折り曲げられ、昇降路の壁面１２に沿わせて配置される。そして、基部１１Ａは、壁面に埋め込まれているアンカーボルト１３などを用いて壁面１２に固定される。 The wall-side bracket 11 has a base portion 11A arranged along the wall surface 12 of the hoistway, and a horizontal portion 11B bent at a substantially right angle to the base portion 11A and arranged substantially horizontally. The wall side bracket 11 is formed in an L shape when viewed from the side surface. Further, the wall side bracket 11 is arranged along the wall surface 12 of the hoistway with the base portion 11A bent downward with respect to the horizontal portion 11B. Then, the base portion 11A is fixed to the wall surface 12 by using anchor bolts 13 or the like embedded in the wall surface.
　レール側ブラケット１４は、水平部１４Ａと、この水平部１４Ａに対してほぼ直角に折り曲げられた垂直部１４Ｂを有している。レール側ブラケット１４は側面から見た形状が、Ｌ字状に形成されている。 The rail-side bracket 14 has a horizontal portion 14A and a vertical portion 14B bent at a substantially right angle to the horizontal portion 14A. The rail-side bracket 14 is formed in an L-shape when viewed from the side surface.
　壁側ブラケット１１における水平部１１Ｂの上面側には、レール側ブラケット１４における水平部１４Ａが載置され、水平部１１Ｂと水平部１４Ａの重なり部分が二本の第１ボルト１５Ａおよび第２ボルト１５Ｂとナット１６Ａおよびナット１６Ｂによって連結される。このようにして、壁側ブラケット１１とレール側ブラケット１４が連結される。壁側ブラケット１１とレール側ブラケット１４が連結された状態において、レール側ブラケット１４の垂直部１４Ｂは水平部１４Ａに対して上方向に折り曲げられている。 The horizontal portion 14A of the rail side bracket 14 is placed on the upper surface side of the horizontal portion 11B of the wall side bracket 11, and the overlapping portion of the horizontal portion 11B and the horizontal portion 14A has two first bolts 15A and a second bolt 15B. And nut 16A and nut 16B. In this way, the wall-side bracket 11 and the rail-side bracket 14 are connected. In a state where the wall-side bracket 11 and the rail-side bracket 14 are connected, the vertical portion 14B of the rail-side bracket 14 is bent upward with respect to the horizontal portion 14A.
　ここで第１ボルト１５Ａを用いた連結部について説明する。壁側ブラケット１１における水平部１１Ｂには、図２及び図３に示すように第１縦長穴１７Ａが形成されている。この第１縦長穴１７Ａはガイドレール２Ａから昇降路の壁面１２に向かって延びている。換言すると、第１縦長穴１７Ａはガイドレール２Ａが昇降路の壁面１２から離接する方向に延びるように形成されている。 Here, the connecting portion using the first bolt 15A will be described. As shown in FIGS. 2 and 3, a first vertically elongated hole 17A is formed in the horizontal portion 11B of the wall-side bracket 11. The first vertically elongated hole 17A extends from the guide rail 2A toward the wall surface 12 of the hoistway. In other words, the first vertically elongated hole 17A is formed so that the guide rail 2A extends in the direction in which the guide rail 2A is separated from the wall surface 12 of the hoistway.
　これに対して、レール側ブラケット１４における水平部１４Ａには、第２横長穴１８Ａが形成されている。この第２横長穴１８Ａは、左右方向に延びている。換言すると、第２横長穴１８Ａは第１縦長穴１７Ａと直交する方向に延びるように形成されている。このように、第１縦長穴１７Ａと第２横長穴１８Ａの長手方向の向きは、互いが直交するような向きにとなっている。 On the other hand, a second horizontally elongated hole 18A is formed in the horizontal portion 14A of the rail side bracket 14. The second horizontally elongated hole 18A extends in the left-right direction. In other words, the second horizontally elongated hole 18A is formed so as to extend in a direction orthogonal to the first vertically elongated hole 17A. As described above, the orientations of the first vertically elongated hole 17A and the second horizontally elongated hole 18A in the longitudinal direction are such that they are orthogonal to each other.
　そして、これら第１縦長穴１７Ａと第２横長穴１８Ａが重なった位置には、レール側ブラケット１４の側から第１ボルト１５Ａが挿入され、その挿入側先端部にナット１６Ａを螺合して締め付けることにより壁側ブラケット１１とレール側ブラケット１４とが結合される。 Then, the first bolt 15A is inserted from the side of the rail side bracket 14 at the position where the first vertically elongated hole 17A and the second horizontally elongated hole 18A overlap, and the nut 16A is screwed and tightened to the insertion side tip portion. As a result, the wall side bracket 11 and the rail side bracket 14 are combined.
　次に、第２ボルト１５Ｂを用いた連結部について説明する。壁側ブラケット１１における水平部１１Ｂには、図２及び図３に示すように第１横長穴１７Ｂが形成されている。この第１横長穴１７Ｂは、長手方向が左右方向に延びている。換言すると、第１横長穴１７Ｂは、第１縦長穴１７Ａと直交する方向に延びて形成されている。 Next, the connecting portion using the second bolt 15B will be described. A first horizontally elongated hole 17B is formed in the horizontal portion 11B of the wall-side bracket 11 as shown in FIGS. 2 and 3. The longitudinal direction of the first horizontally elongated hole 17B extends in the left-right direction. In other words, the first horizontally elongated hole 17B is formed so as to extend in a direction orthogonal to the first vertically elongated hole 17A.
　これに対して、レール側ブラケット１４における水平部１４Ａには、第２縦長穴１８Ｂが形成されている。この第２縦長穴１８Ｂはガイドレール２Ａから昇降路の壁面１２に向かって延びている。換言すると、第２縦長穴１８Ｂはガイドレール２Ａが昇降路の壁面１２から離接する方向に延びるように形成されている。このように、第１横長穴１７Ｂと第２縦長穴１８Ｂとの長手方向の向きは、互いが直交するような向きにとなっている。また、上述した第２横長穴１８Ａは、第２縦長穴１８Ｂと直交する方向に延びて形成されている。 On the other hand, a second vertically elongated hole 18B is formed in the horizontal portion 14A of the rail side bracket 14. The second vertically elongated hole 18B extends from the guide rail 2A toward the wall surface 12 of the hoistway. In other words, the second vertically elongated hole 18B is formed so that the guide rail 2A extends in the direction in which the guide rail 2A is separated from the wall surface 12 of the hoistway. As described above, the orientations of the first horizontally elongated hole 17B and the second vertically elongated hole 18B in the longitudinal direction are such that they are orthogonal to each other. Further, the above-mentioned second horizontally elongated hole 18A is formed so as to extend in a direction orthogonal to the second vertically elongated hole 18B.
　そして、これら第１横長穴１７Ｂと第２縦長穴１８Ｂが重なった位置には、レール側ブラケット１４の側から第２ボルト１５Ｂが挿入され、その挿入側先端部にナット１６Ｂを螺合して締め付けることにより壁側ブラケット１１とレール側ブラケット１４とが結合される。 A second bolt 15B is inserted from the side of the rail-side bracket 14 at a position where the first horizontally elongated hole 17B and the second vertically elongated hole 18B overlap, and a nut 16B is screwed into the insertion-side tip and tightened. As a result, the wall side bracket 11 and the rail side bracket 14 are combined.
　第１ボルト１５Ａを中心とする第１縦長穴１７Ａおよび第２横長穴１８Ａと、第２ボルト１５Ｂを中心とする第１横長穴１７Ｂおよび第２縦長穴１８Ｂは、全体として互いにほぼ同じ形状であるが、長手方向に向きが同じである第１縦長穴１７Ａと第２縦長穴１８Ｂとは互いの長手方向の延長線上には位置しておらず、また長手方向に向きが同じである第２横長穴１８Ａと第１横長穴１７Ｂとは互いの長手方向の延長線上には位置しないようにしている。換言すると、第１縦長穴１７Ａと第２縦長穴１８Ｂとは互いの長手方向延長線上の位置からずらして配置し、また、第２横長穴１８Ａと第１横長穴１７Ｂとは互いの長手方向延長線上の位置からずらして配置している。 The first vertical hole 17A and the second horizontal hole 18A centered on the first bolt 15A, and the first horizontal hole 17B and the second vertical hole 18B centered on the second bolt 15B have substantially the same shape as a whole. However, the first longitudinal hole 17A and the second longitudinal hole 18B having the same orientation in the longitudinal direction are not located on the extension lines in the longitudinal direction of each other, and the second oblong hole has the same orientation in the longitudinal direction. The hole 18A and the first horizontally elongated hole 17B are not located on an extension line in the longitudinal direction of each other. In other words, the first vertical hole 17A and the second vertical hole 18B are arranged so as to be offset from each other's positions on the longitudinal extension line, and the second horizontal hole 18A and the first horizontal hole 17B are mutually extended in the longitudinal direction. It is placed offset from the position on the line.
　壁面１２とガイドレール２Ａを結ぶ線を直線Ｌ１とし、この直線Ｌ１に対して同一水平面上で斜めに交差する線を直線Ｌ２としたとき、第１ボルト１５Ａと第２ボルト１５Ｂとは、直線Ｌ１を挟み、かつ直線Ｌ２を境界として互いが対向するように配置している。 When the line connecting the wall surface 12 and the guide rail 2A is a straight line L1 and the line diagonally intersecting the straight line L1 on the same horizontal plane is a straight line L2, the first bolt 15A and the second bolt 15B are straight lines L1. Are placed so as to face each other with the straight line L2 as a boundary.
　第２ボルト１５Ｂの位置は、第１ボルト１５Ａに隣接しているが、壁面１２から第１ボルト１５Ａまでの距離と同じ距離の位置ではなく、ガイドレール２Ａ側に寄せて配置している。このため、上述した第１縦長穴１７Ａの長手方向の延長線上に第２縦長穴１８Ｂが位置せず、かつ、第２横長穴１８Ａの長手方向の延長線上に第１横長穴１７Ｂが位置していない。 The position of the second bolt 15B is adjacent to the first bolt 15A, but it is not located at the same distance as the distance from the wall surface 12 to the first bolt 15A, but is placed closer to the guide rail 2A side. Therefore, the second vertically elongated hole 18B is not located on the extension line of the first vertically elongated hole 17A in the longitudinal direction, and the first horizontally elongated hole 17B is located on the extension line of the second horizontally elongated hole 18A in the longitudinal direction. Absent.
　さらに、壁側ブラケット１１に形成された第１縦長穴１７Ａと第１横長穴１７Ｂの長手方向の向きは、一致しておらず、互いが直交するような向きにとなっている。同様にレール側ブラケット１４の第２横長穴１８Ａと第２縦長穴１８Ｂの長手方向の向きは一致しておらず、互いが直交するような向きにとなっている。 Further, the orientations of the first vertically elongated hole 17A and the first horizontally elongated hole 17B formed in the wall side bracket 11 in the longitudinal direction do not match, and are oriented so as to be orthogonal to each other. Similarly, the orientations of the second horizontally elongated holes 18A and the second vertically elongated holes 18B of the rail side bracket 14 in the longitudinal direction do not match, and are oriented so as to be orthogonal to each other.
　上述のようにして壁側ブラケット１１に連結されたレール側ブラケット１４における垂直部１４Ｂには、図３および図４に示すように形成された複数個のボルト用穴を用いてガイドレール２Ａが固定されている。この固定は、ガイドレール２Ａ側から垂直部１４Ｂとガイドレール２Ａの基部側端部に跨がるレールクリップ１９を配置し、レールクリップ１９にガイドレール２Ａ側から挿入した固定ボルト２０を垂直部１４Ｂに形成されたボルト用穴に通し、固定ボルト２０の挿通側端部にナット２１を締め付けて行っている。 The guide rail 2A is fixed to the vertical portion 14B of the rail-side bracket 14 connected to the wall-side bracket 11 as described above by using a plurality of bolt holes formed as shown in FIGS. 3 and 4. Has been done. For this fixing, a rail clip 19 straddling the vertical portion 14B from the guide rail 2A side and the base side end portion of the guide rail 2A is arranged, and a fixing bolt 20 inserted into the rail clip 19 from the guide rail 2A side is inserted into the vertical portion 14B. The nut 21 is tightened to the insertion side end of the fixing bolt 20 through the bolt hole formed in.
　この取り付け状態から分かるように、上述したように壁側ブラケット１１に形成された第１縦長穴１７Ａと、レール側ブラケット１４に形成された第２縦長穴１８Ｂは、ガイドレール２Ａと接離する方向に延びて形成されている。このため、ガイドレール２Ａを固定するときの位置を所定の位置にしたとき、調整による変動量を壁側ブラケット１１とレール側ブラケット１４における第１縦長穴１７Ａ，第２縦長穴１８Ｂ内で、ガイドレール２Ａと接離する方向で調整することができ、その後、ガイドレール２Ａを所定位置に固定することができる。 As can be seen from this mounting state, the first vertically elongated hole 17A formed in the wall side bracket 11 and the second vertically elongated hole 18B formed in the rail side bracket 14 as described above are in the direction of contacting and separating from the guide rail 2A. It is formed by extending to. Therefore, when the position for fixing the guide rail 2A is set to a predetermined position, the amount of fluctuation due to the adjustment is guided in the first vertical hole 17A and the second vertical hole 18B in the wall side bracket 11 and the rail side bracket 14. It can be adjusted in the direction of contact and separation with the rail 2A, and then the guide rail 2A can be fixed in a predetermined position.
　またレール側ブラケット１４に形成された第２横長穴１８Ａと、壁側ブラケット１１に形成された第１横長穴１７Ｂは第１縦長穴１７Ａ，第２縦長穴１８Ｂと直交する方向に延びている。このため、ガイドレール２Ａを固定するときの位置を所定の位置にしたとき、調整による変動量を壁側ブラケット１１とレール側ブラケット１４における第２横長穴１８Ａ，第１横長穴１７Ｂ内で、ガイドレール２Ａと接離する方向に対して直交する方向で調整することができ、その後、ガイドレール２Ａを所定位置に固定することができる。 Further, the second horizontally elongated hole 18A formed in the rail side bracket 14 and the first horizontally elongated hole 17B formed in the wall side bracket 11 extend in a direction orthogonal to the first vertically elongated hole 17A and the second vertically elongated hole 18B. Therefore, when the position for fixing the guide rail 2A is set to a predetermined position, the amount of fluctuation due to the adjustment is guided in the second horizontally elongated holes 18A and the first horizontally elongated holes 17B in the wall side bracket 11 and the rail side bracket 14. It can be adjusted in a direction orthogonal to the direction of contact and separation with the rail 2A, and then the guide rail 2A can be fixed in a predetermined position.
　この状態で、レール側ブラケット１４が滑るモードは、締結用のボルトがレール側ブラケット１４と共に滑る場合と、レール側ブラケット１４のみが滑る場合が考えられる。ここで、レール側ブラケットと壁側ブラケットそれぞれに縦長穴と横長穴のいずれか一方のみが設けられた従来のエレベータ調整式レールブラケット構造では、外部に露出しているレール側ブラケット１４の上面側または壁側ブラケット１１の下面側における摩擦係数が潤滑物の付着など何等かの要因で低下した場合、上述した滑りモードのうち一方のみが集中的に生じてしまう。具体的には、レール側ブラケット１４の図３における上面側において摩擦係数の減少が生じた場合、図３の第２縦長穴１８Ｂだけが壁側ブラケット１１に設置された構造では、縦方向の力が負荷されると、縦長穴に沿ってレール側ブラケット１４のみが滑るモードが生じてしまう。 In this state, the mode in which the rail side bracket 14 slides may be the case where the fastening bolt slides together with the rail side bracket 14 or the case where only the rail side bracket 14 slides. Here, in the conventional elevator adjustable rail bracket structure in which only one of the vertically elongated hole and the horizontally elongated hole is provided in each of the rail side bracket and the wall side bracket, the upper surface side of the rail side bracket 14 exposed to the outside or When the coefficient of friction on the lower surface side of the wall-side bracket 11 decreases due to some factor such as adhesion of lubricant, only one of the above-mentioned sliding modes is intensively generated. Specifically, when the friction coefficient is reduced on the upper surface side of the rail side bracket 14 in FIG. 3, in the structure in which only the second vertically elongated hole 18B in FIG. 3 is installed on the wall side bracket 11, the force in the vertical direction is applied. Is applied, a mode in which only the rail-side bracket 14 slides along the vertically elongated hole occurs.
　一方、壁側ブラケット１１の図３における下面側において摩擦係数の減少が生じた場合、図３の第２横長穴１８Ａだけが壁側ブラケット１１に設置された構造では、横方向の力が負荷されると、横長穴に沿ってボルトとレール側ブラケット１４が共に滑るモードが生じてしまう。 On the other hand, when the friction coefficient is reduced on the lower surface side of the wall side bracket 11 in FIG. 3, a lateral force is applied in the structure in which only the second horizontally elongated hole 18A in FIG. 3 is installed on the wall side bracket 11. Then, a mode in which the bolt and the rail-side bracket 14 slide together along the horizontally elongated hole occurs.
　しかしながら、上述した本実施例の構成によれば、レール側ブラケット１４には穴の長手方向が異なる第２縦長穴１８Ｂと第２横長穴１８Ａが混在し、また壁側ブラケット１１には穴の長手方向が異なる第１縦長穴１７Ａと第１横長穴１７Ｂがそれぞれ混在している。このため、レール側ブラケット１４の図２における上面側において摩擦係数が減少し、縦方向の力が負荷されレール側ブラケット１４のみが滑るモードが生じた場合も、第２横長穴１８Ａにおいて第１ボルト１５Ａが長穴周縁部に強制的に当たるため、壁側ブラケット１１の下面側での摩擦力が発揮されることになる。 However, according to the configuration of the present embodiment described above, the rail-side bracket 14 contains a mixture of second vertically elongated holes 18B and second horizontally elongated holes 18A having different hole longitudinal directions, and the wall-side bracket 11 has a hole length. The first vertically elongated holes 17A and the first horizontally elongated holes 17B having different directions are mixed. Therefore, even when the friction coefficient is reduced on the upper surface side of the rail side bracket 14 in FIG. 2 and a vertical force is applied to cause a mode in which only the rail side bracket 14 slides, the first bolt is formed in the second horizontally elongated hole 18A. Since the 15A forcibly hits the peripheral edge of the elongated hole, the frictional force on the lower surface side of the wall side bracket 11 is exerted.
　一方、壁側ブラケット１１の図３における下面側において摩擦係数が減少し、横方向の力が負荷され第１ボルト１５Ａ、第２ボルト１５Ｂとレール側ブラケット１４が共に滑るモードが生じた場合も、第１縦長穴１７Ａにおいて第１ボルト１５Ａが長穴周縁部に強制的に当たるため、レール側表面での摩擦力が発揮されることになる。以上により、本実施例を用いることで、簡単な構成で建屋施工誤差を調整可能とすると共に、壁側ブラケットとレール側ブラケットの接合部がずれにくくすることができる。 On the other hand, even when the friction coefficient is reduced on the lower surface side of the wall side bracket 11 in FIG. 3 and a lateral force is applied to cause a mode in which the first bolt 15A, the second bolt 15B and the rail side bracket 14 slide together. In the first vertically elongated hole 17A, the first bolt 15A forcibly hits the peripheral edge of the elongated hole, so that the frictional force on the rail side surface is exerted. As described above, by using this embodiment, it is possible to adjust the building construction error with a simple configuration, and it is possible to prevent the joint portion between the wall side bracket and the rail side bracket from slipping.
　また、上述したように本実施例では、第１縦長穴１７Ａと第２縦長穴１８Ｂが穴の長手方向延長線上に位置せず、第２横長穴１８Ａと第１横長穴１７Ｂが穴の長手方向延長線上に位置しないように、壁面１２とガイドレール２Ａを結ぶ直線Ｌ１と、この想定した直線Ｌ１に対して同一水平面で斜めに交差する斜め直線Ｌ２を想定したとき、斜め直線Ｌ２上で対向するように第１ボルト１５Ａと第２ボルト１５Ｂを配置している。このため、片方の第１ボルト１５Ａまたは第２ボルト１５Ｂを中心としてレール側ブラケット１４が回転してしまうのを防止することができる。 Further, as described above, in the present embodiment, the first elongated hole 17A and the second elongated hole 18B are not located on the extension line in the longitudinal direction of the hole, and the second elongated hole 18A and the first elongated hole 17B are in the longitudinal direction of the hole. When a straight line L1 connecting the wall surface 12 and the guide rail 2A and a diagonal straight line L2 diagonally intersecting the assumed straight line L1 on the same horizontal plane are assumed so as not to be located on the extension line, they face each other on the diagonal straight line L2. The first bolt 15A and the second bolt 15B are arranged as described above. Therefore, it is possible to prevent the rail-side bracket 14 from rotating around one of the first bolts 15A or the second bolt 15B.
　本実施例では、壁側ブラケット１１とレール側ブラケット１４の締結手段として第１ボルト１５Ａ、第２ボルト１５Ｂを用いたが、締結手段の形態は問わない。本実施例では、第１縦長穴１７Ａと第２横長穴１８Ａ、第１横長穴１７Ｂと第２縦長穴１８Ｂのそれぞれに挿入されて締結するものをボルトと称する。 In this embodiment, the first bolt 15A and the second bolt 15B are used as the fastening means for the wall side bracket 11 and the rail side bracket 14, but the form of the fastening means does not matter. In this embodiment, a bolt that is inserted and fastened into each of the first elongated hole 17A and the second elongated hole 18A, and the first elongated hole 17B and the second elongated hole 18B is referred to as a bolt.
