One end of the second opening/closing portion 23 is rotatably connected to the first opening/closing portion 22 with the first shaft 27 as a fulcrum. The second opening/closing part 23 has an adjustment hole 29 that opens in the tangential direction along which the second opening/closing part 23 rotates.
　開閉ボルト部２４の長手方向の一端部は、第２軸２８を支点として、第１開閉部２２と回転可能に繋がる。具体的には、開閉ボルト部２４は、第２開閉部２３が第１開閉部２２に対して回転する平面と同一の平面を回転し得るよう設けられる。開閉ボルト部２４の長手方向の他端部は、第２開閉部２３の調整孔２９に挿通可能に形成される。 One longitudinal end of the opening/closing bolt portion 24 is rotatably connected to the first opening/closing portion 22 with the second shaft 28 as a fulcrum. Specifically, the opening/closing bolt portion 24 is provided so as to rotate in the same plane as the second opening/closing portion 23 rotates with respect to the first opening/closing portion 22 . The other longitudinal end of the opening/closing bolt portion 24 is formed so as to be able to be inserted into the adjustment hole 29 of the second opening/closing portion 23 .
　開閉ナット部２５は、開閉ボルト部２４に対応するナットである。 The opening/closing nut portion 25 is a nut corresponding to the opening/closing bolt portion 24 .
　固定部２６は、第１開閉部２２の他端側に設けられる。例えば、固定部２６は、第１開閉部２２を貫通するボルトである。固定部２６は、支持部材１２の取付体１６における取付部２１に取り付け可能に設けられる。 The fixed part 26 is provided on the other end side of the first opening/closing part 22 . For example, the fixing portion 26 is a bolt passing through the first opening/closing portion 22 . The fixing portion 26 is provided so as to be attachable to the attachment portion 21 of the attachment body 16 of the support member 12 .
　結合部材１１は、固定部２６によって支持部材１２に固定される。この際、第１開閉部２２の一端側は、支持部材１２の連結部１９に接する。第１開閉部２２の他端側は、支持部材１２の取付体１６に接する。第２開閉部２３と開閉ボルト部２４とは、第１開閉部２２に対して９０度程度まで回転し得る。 The coupling member 11 is fixed to the support member 12 by the fixing portion 26 .

Although not shown, the coupling member 11 is in an open state when the opening/closing bolt portion 24 is not inserted through the adjustment hole 29 .
　結合部材１１が開状態である場合に、棒部材１０は、結合部材１１の開閉口３０が形成される位置に配置され得る。棒部材１０が結合部材１１の開閉口３０に配置された状態で結合部材１１が閉状態となることで、棒部材１０は、結合部材１１に固定される。 When the coupling member 11 is in the open state, the rod member 10 can be arranged at a position where the opening/closing port 30 of the coupling member 11 is formed. The rod member 10 is fixed to the coupling member 11 by closing the coupling member 11 while the rod member 10 is arranged in the opening/closing port 30 of the coupling member 11 .
　次に、図６から図８を用いて、運搬工具９をエスカレーター１に設置する方法を説明する。
　図６は実施の形態１における運搬工具を設置する方法の第１固定工程が行われた乗客コンベアの要部を示す図である。図７は実施の形態１における運搬工具を設置する方法の第２固定工程が行われた乗客コンベアの要部を示す図である。図８は実施の形態１における運搬工具を設置する方法の第３固定工程が行われた乗客コンベアの要部を示す図である。 Next, a method of installing the carrying tool 9 on the escalator 1 will be described with reference to FIGS. 6 to 8. FIG.

FIG. 7 is a diagram showing the main part of the passenger conveyor on which the second fixing step of the method of installing the carrying tool according to Embodiment 1 has been performed. FIG. 8 is a diagram showing the essential parts of the passenger conveyor on which the third fixing step of the method of installing the carrying tool according to Embodiment 1 has been performed.
　図６には、一対の支持部材１２の一方が示される。運搬工具の設置方法の第１固定工程において、一対の支持部材１２は、一対の手すり４にそれぞれ固定される。この際、一対の支持部材１２の各々は、長手方向が手すり４の移動方向を向くように固定される。 One of the pair of support members 12 is shown in FIG. In the first fixing step of the carrying tool installation method, the pair of support members 12 are fixed to the pair of handrails 4, respectively. At this time, each of the pair of support members 12 is fixed so that its longitudinal direction faces the moving direction of the handrail 4 .
　その後、運搬工具の設置方法の第２固定工程が行われる。図７に示されるように、第２固定工程において、一対の結合部材１１は、一対の支持部材１２にそれぞれ固定される。この際、一対の結合部材１１の一方は、開閉口３０が一対の結合部材１１の他方を向くように固定される。一対の結合部材１１の他方は、開閉口３０が一対の結合部材１１の一方を向くように固定される。 After that, the second fixing step of the installation method of the carrying tool is performed. As shown in FIG. 7, in the second fixing step, the pair of coupling members 11 are fixed to the pair of support members 12, respectively. At this time, one of the pair of coupling members 11 is fixed so that the opening/closing port 30 faces the other of the pair of coupling members 11 . The other of the pair of coupling members 11 is fixed so that the opening/closing port 30 faces one of the pair of coupling members 11 .
　その後、運搬工具の設置方法の第３固定工程が行われる。図８に示されるように、第３固定工程において、棒部材１０は、開閉口３０において一対の結合部材１１のそれぞれに固定される。 After that, the third fixing step of the installation method of the carrying tool is performed. As shown in FIG. 8 , in the third fixing step, the rod member 10 is fixed to each of the pair of coupling members 11 at the opening/closing port 30 .
　その後、運搬工具の設置方法の揚重装置取付工程が行われる。揚重装置取付工程において、図８には図示されない揚重装置１３は、棒部材１０の中間位置に取り付けられる。揚重装置取付工程が終了した場合、運搬工具９の設置が完了する。 After that, the lifting device installation process of the transportation tool installation method is performed. In the lifting device mounting step, the lifting device 13 not shown in FIG. When the lifting device mounting process is finished, the installation of the transport tool 9 is completed.
　以上で説明した実施の形態１によれば、運搬工具９は、棒部材１０と一対の結合部材１１と一対の支持部材１２とを備える。一対の支持部材１２は、エスカレーター１において両側の手すり４のそれぞれを両側方から把持することで両側の手すり４にそれぞれ固定される。このため、運搬工具９を安定して設置できる。 According to Embodiment 1 described above, the carrying tool 9 includes the rod member 10, the pair of coupling members 11, and the pair of support members 12. The pair of support members 12 are fixed to the handrails 4 on both sides of the escalator 1 by gripping the handrails 4 on both sides. Therefore, the carrying tool 9 can be stably installed.
　また、支持部材１２は、第１支持体である一対の支持体１４の一方と第２支持体である一対の支持体１４の他方と連結ボルト１５ａと連結ナット１５ｂとを備える。このため、支持部材１２は、手すり４を適切な力で把持することができる。 In addition, the support member 12 includes one of a pair of support bodies 14 as a first support body, the other of the pair of support bodies 14 as a second support body, a connection bolt 15a, and a connection nut 15b. Therefore, the support member 12 can grip the handrail 4 with an appropriate force.
　また、一対の結合部材１１の一方は、一対の支持部材１２の一方が手すり４に固定された状態で棒部材１０を着脱自在に固定する。このため、運搬工具９を設置する際に、棒部材１０を仮設置した後、当該棒部材１０を一度取り外してから一対の支持部材１２の取り付け位置を容易に調整することができる。その結果、運搬工具９を設置する作業の効率を向上できる。 One of the pair of connecting members 11 detachably fixes the rod member 10 while one of the pair of supporting members 12 is fixed to the handrail 4 . For this reason, when installing the carrying tool 9, after temporarily installing the rod member 10, the mounting position of the pair of support members 12 can be easily adjusted after removing the rod member 10 once. As a result, the efficiency of the work for installing the carrying tool 9 can be improved.
　また、一対の結合部材１１は、第１開閉部２２と第２開閉部２３と開閉ボルト部２４と開閉ナット部２５とを有する。このため、一対の結合部材１１は、棒部材１０を容易に着脱することができる。また、径が異なる様々な種類の棒部材１０を固定することができる。 Also, the pair of coupling members 11 has a first opening/closing portion 22 , a second opening/closing portion 23 , an opening/closing bolt portion 24 and an opening/closing nut portion 25 . Therefore, the rod member 10 can be easily attached to and detached from the pair of coupling members 11 . Moreover, various kinds of rod members 10 having different diameters can be fixed.
　なお、棒部材１０は、長手方向に伸縮可能に設けられてもよい。例えば、棒部材１０は、図示されない第１棒部材と第２棒部材とから構成されてもよい。この場合、第１棒部材は、内部に空洞を有する。第２棒部材は、第１棒部材の空洞の内部を移動可能な径を有する。第２棒部材が第１棒部材の内部を移動することで、棒部材１０は、長手方向に伸縮する。このため、運搬工具９は、一対の手すり４の間の距離が異なる複数のエスカレーター１に適用することができる。また、手すり４に対して移動経路２とは反対側に存在する物体と棒部材１０とが干渉することを抑制できる。 It should be noted that the bar member 10 may be provided so as to extend and contract in the longitudinal direction. For example, the bar member 10 may be composed of a first bar member and a second bar member (not shown). In this case, the first rod member has a cavity inside. The second rod member has a diameter that allows it to move within the cavity of the first rod member. As the second rod member moves inside the first rod member, the rod member 10 expands and contracts in the longitudinal direction. Therefore, the carrying tool 9 can be applied to multiple escalators 1 having different distances between the pair of handrails 4 . Moreover, it is possible to suppress interference between an object existing on the opposite side of the moving path 2 with respect to the handrail 4 and the bar member 10 .
　また、運搬工具の設置方法は、第１固定工程と第２固定工程と第３固定工程とを備える。第１固定工程および第２固定工程において、一対の支持部材１２と一対の結合部材１１とは、棒部材１０で連結されることなくそれぞれ独立に設置される。このため、運搬工具の設置を容易に行うことができる。 Also, the installation method of the carrying tool includes a first fixing step, a second fixing step, and a third fixing step. In the first fixing step and the second fixing step, the pair of supporting members 12 and the pair of connecting members 11 are installed independently without being connected by the rod members 10 . Therefore, it is possible to easily install the carrying tool.
　なお、第３固定工程の後に、エスカレーター１を稼働させて複数のステップ６と手すり４とを連動して移動させる移動工程が行われてもよい。この際、棒部材１０が運搬工具９の運搬する部品であるディスクブレーキ７ａの上方に位置するように手すり４を移動させてもよい。このため、運搬工具９の位置を容易に調整することができる。 After the third fixing process, a moving process may be performed in which the escalator 1 is operated to move the plurality of steps 6 and the handrail 4 in conjunction. At this time, the handrail 4 may be moved so that the bar member 10 is positioned above the disk brake 7a, which is a component that the carrying tool 9 carries. Therefore, the position of the carrying tool 9 can be easily adjusted.
　また、エスカレーター１が複数のドライブユニット７を有する場合、１つ目のドライブユニット７におけるディスクブレーキ７ａの運搬作業が完了した後に、移動工程が行われてもよい。この場合、運搬工具９は、手すり４に設置された状態で２つ目以降のドライブユニット７の上方まで移動される。このため、運搬工具９を取り外すことなく複数のドライブユニット７の保守作業を行うことができる。また、開口部８が手すり４に設置された運搬工具９と連動して移動するため、保守作業において、新たに複数のステップ６を取り外す作業を省くことができる。その結果、保守作業の効率が向上する。 Further, when the escalator 1 has a plurality of drive units 7, the moving process may be performed after the work of transporting the disc brakes 7a in the first drive unit 7 is completed. In this case, the carrying tool 9 is moved above the second and subsequent drive units 7 while being installed on the handrail 4 . Therefore, maintenance work can be performed on a plurality of drive units 7 without removing the carrying tool 9 . In addition, since the opening 8 moves in conjunction with the carrying tool 9 installed on the handrail 4, it is possible to omit the work of newly removing the plurality of steps 6 in the maintenance work. As a result, the efficiency of maintenance work is improved.
　なお、取付穴１９ａは、連結部１９の長手方向における連結部１９の中央部に設けられてもよい。 Note that the mounting hole 19a may be provided in the central portion of the connecting portion 19 in the longitudinal direction of the connecting portion 19 .
　以上のように、本開示に係る運搬工具は、乗客コンベアに利用できる。 As described above, the carrying tool according to the present disclosure can be used for passenger conveyors.
