１－２．エレベーター用作業台の構成例
　次に、図３～図８を参照して作業台１０の詳細な構成について説明する。
　図３は、作業台１０を示す斜視図、図４は、作業台１０を乗りかご１２０に設置した状態を示す平面図、図５は、作業台１０を示す側面図である。 1-2. Next, a detailed configuration of the work table 10 will be described with reference to FIGS. 3 to 8. FIG.
3 is a perspective view showing the workbench 10, FIG. 4 is a plan view showing a state where the workbench 10 is installed on the car 120, and FIG. 5 is a side view showing the workbench 10.
　図３～図５に示すように、作業台１０は、第１連結部材１１と、第２連結部材１２と、作業床組立体１５と、落下防止冊１６と、を備えている。第１連結部材１１は、上梁１２１の長手方向の一端部に固定され、第２連結部材１２は、上梁１２１の長手方向の中間部に固定される。第１連結部材１１及び第２連結部材１２は、それぞれ固定ボルト６１を介して上梁１２１に着脱可能に固定される。また、作業床組立体１５は、第１連結部材１１及び第２連結部材１２に支持ボルト６２を介して着脱可能に固定される。 3 to 5, the work table 10 includes a first connecting member 11, a second connecting member 12, a work floor assembly 15, and a fall prevention book 16. The first connecting member 11 is fixed to one end portion in the longitudinal direction of the upper beam 121, and the second connecting member 12 is fixed to an intermediate portion in the longitudinal direction of the upper beam 121. The first connecting member 11 and the second connecting member 12 are detachably fixed to the upper beam 121 via fixing bolts 61, respectively. The work floor assembly 15 is detachably fixed to the first connecting member 11 and the second connecting member 12 via support bolts 62.
　図６は、第１連結部材１１を示す平面図、図７は、第１連結部材１１を示す側面図である。
　図６及び図７に示すように、第１連結部材１１は、固定面部２１と、支持面部２２と、規制板２３と、保護カバー２４とを有している。 FIG. 6 is a plan view showing the first connecting member 11, and FIG. 7 is a side view showing the first connecting member 11.
As shown in FIGS. 6 and 7, the first connecting member 11 includes a fixed surface portion 21, a support surface portion 22, a regulating plate 23, and a protective cover 24.
　固定面部２１は、矩形状の略平板状に形成されている。固定面部２１には、固定ボルト６１（図５参照）が螺合する締結孔２１ａが設けられている。図５に示すように、固定面部２１は、上梁１２１の上面部１２１ａに載置され、上梁１２１に固定ボルト６１を介して締結固定される。固定面部２１における一端部には、支持面部２２が略垂直に連続して形成されている。 The fixed surface portion 21 is formed in a rectangular substantially flat plate shape. The fixing surface portion 21 is provided with a fastening hole 21a into which a fixing bolt 61 (see FIG. 5) is screwed. As shown in FIG. 5, the fixed surface portion 21 is placed on the upper surface portion 121 a of the upper beam 121 and is fastened and fixed to the upper beam 121 via the fixing bolt 61. At one end portion of the fixed surface portion 21, a support surface portion 22 is continuously formed substantially vertically.
　支持面部２２は、固定面部２１の一端部から上下方向の上方に向けて略垂直に屈曲している。支持面部２２には、支持ボルト６２が螺合する締結部２２ａが設けられている。図５に示すように、支持面部２２には、後述する作業床組立体１５の支持柱３１が支持ボルト６２を介して締結固定される。また、固定面部２１と支持面部２２との角部には、固定面部２１と支持面部２２とを連結するようにして補強面部２５が設けられている。 The support surface portion 22 is bent substantially vertically from one end portion of the fixed surface portion 21 upward in the vertical direction. The support surface portion 22 is provided with a fastening portion 22a into which the support bolt 62 is screwed. As shown in FIG. 5, a support column 31 of a work floor assembly 15 described later is fastened and fixed to the support surface portion 22 via a support bolt 62. Further, a reinforcing surface portion 25 is provided at a corner portion between the fixed surface portion 21 and the support surface portion 22 so as to connect the fixed surface portion 21 and the support surface portion 22.
　固定面部２１における支持面部２２が設けられた一端部と反対側の他端部には、規制板２３が設けられている。規制板２３は、固定面部２１における補強面部２５が設けられた端部とは反対側の端部から上下方向の下方に向けて略垂直に屈曲している。固定面部２１を上梁１２１に上面部１２１ａに載置した際に、規制板２３は、収容部材１３１の収容凹部１３１ａに挿入される。 A regulating plate 23 is provided at the other end of the fixed surface 21 opposite to the one end where the support surface 22 is provided. The restriction plate 23 is bent substantially vertically from the end of the fixed surface 21 opposite to the end where the reinforcing surface 25 is provided, downward in the vertical direction. When the fixed surface portion 21 is placed on the upper beam 121 on the upper beam 121, the restriction plate 23 is inserted into the housing recess 131 a of the housing member 131.
　また、固定面部２１の他端部には、保護カバー２４が固定ねじ２８によって取り付けられている。保護カバー２４は、固定面部２１の他端部から所定の長さで突出し、先端部が上下方向の下方に向けて屈曲している。固定面部２１を上梁１２１に上面部１２１ａに載置した際に、保護カバー２４は、停止装置１３０のスイッチ１３６の上下方向の上方を覆う。 Further, a protective cover 24 is attached to the other end portion of the fixed surface portion 21 by a fixing screw 28. The protective cover 24 protrudes from the other end portion of the fixed surface portion 21 with a predetermined length, and the distal end portion is bent downward in the vertical direction. When the fixed surface portion 21 is placed on the upper beam 121 on the upper beam 121, the protective cover 24 covers the upper portion of the switch 136 of the stop device 130 in the vertical direction.
　また、図３及び図４に示すように、第２連結部材１２は、第１連結部材１１と同様に、固定面部２１と、支持面部２２とを有している。そして、第２連結部材１２は、第１連結部材１１から規制板２３と保護カバー２４を除いた構成をしており、その他の構成は同一であるためその説明は省略する。 Further, as shown in FIGS. 3 and 4, the second connecting member 12 has a fixed surface portion 21 and a support surface portion 22, similarly to the first connecting member 11. The second connecting member 12 has a configuration in which the restriction plate 23 and the protective cover 24 are removed from the first connecting member 11, and the other configurations are the same, and thus the description thereof is omitted.
　次に、作業床組立体１５について説明する。
　図８は、作業床組立体１５を折り畳んだ状態を示す側面図である。 Next, the work floor assembly 15 will be described.
FIG. 8 is a side view showing a state in which the work floor assembly 15 is folded.
　図３～図５に示すように、作業床組立体１５は、２つの支持柱３１、３１と、ベース部３２と、床部材３４とを有している。２つの支持柱３１、３１は、第１連結部材１１又は第２連結部材１２に支持ボルト６２を介して固定される。また、図５に示すように、支持柱３１の上下方向の下端部は、上梁１２１の側面部１２１ｃに固定ボルト６３を介して締結固定される。 As shown in FIGS. 3 to 5, the work floor assembly 15 has two support columns 31, 31, a base portion 32, and a floor member. The two support columns 31, 31 are fixed to the first connecting member 11 or the second connecting member 12 via support bolts 62. As shown in FIG. 5, the lower end portion of the support column 31 in the vertical direction is fastened and fixed to the side surface portion 121 c of the upper beam 121 via a fixing bolt 63.
　また、図３に示すように、２つの支持柱３１、３１を連結するようにして補強部材５２が固定されている。さらに、図５に示すように、支持柱３１には、係止部３１ａが形成されている。係止部３１ａは、支持柱３１の上下方向の下端部において上梁１２１とは反対側の端部を切り欠くことで形成されている。 Further, as shown in FIG. 3, the reinforcing member 52 is fixed so as to connect the two support columns 31, 31. Further, as shown in FIG. 5, the support column 31 is formed with a locking portion 31 a. The locking portion 31 a is formed by cutting out the end opposite to the upper beam 121 at the lower end in the vertical direction of the support column 31.
　支持柱３１の上下方向の上端部には、回動軸３６が取り付けられている。この回動軸３６には、ベース部３２が回動可能に支持されている。そのため、２つの支持柱３１、３１とベース部３２は、回動軸３６を介して連結される。 A rotating shaft 36 is attached to the upper end of the support column 31 in the vertical direction. A base portion 32 is rotatably supported on the rotation shaft 36. Therefore, the two support columns 31 and 31 and the base portion 32 are connected via the rotation shaft 36.
　図８に示すように、２つの支持柱３１、３１を、回動軸３６を中心に回動させることで、２つの支持柱３１、３１とベース部３２が重なり合う。これにより、作業床組立体１５を小さく折り畳むことができ、作業床組立体１５の運搬作業を容易に行うことができる。さらに、作業床組立体１５を保管する際のスペースの低減を図ることもできる。 As shown in FIG. 8, the two support columns 31, 31 and the base portion 32 overlap each other by rotating the two support columns 31, 31 around the rotation shaft 36. Thereby, the work floor assembly 15 can be folded small, and the work work of the work floor assembly 15 can be performed easily. Furthermore, the space for storing the work floor assembly 15 can be reduced.
　ベース部３２は、略平板状に形成されている。ベース部３２の一面には、複数の開口部３２ａが形成されている。これにより、作業床組立体１５の軽量化を図ることができる。ベース部３２の側面部には、支持体３７が回動可能に取り付けられている。 The base portion 32 is formed in a substantially flat plate shape. A plurality of openings 32 a are formed on one surface of the base portion 32. Thereby, weight reduction of the work floor assembly 15 can be achieved. A support body 37 is rotatably attached to a side surface portion of the base portion 32.
　支持体３７は、棒状の部材を屈曲することで形成されている。支持体３７の一端部には、回動ピン３７ａが設けられている。回動ピン３７ａは、ベース部３２の側面部に回動可能に支持されている。また、作業床組立体１５を展開した後に、支持体３７の一端部とは反対側の他端部には、係止片３７ｂが設けられている。係止片３７ｂは、係止部３１ａに着脱可能に係止される。そのため、支持体３７は、ベース部３２と支持柱３１の間に介在される。 The support body 37 is formed by bending a rod-shaped member. A rotating pin 37 a is provided at one end of the support 37. The rotation pin 37a is rotatably supported on the side surface portion of the base portion 32. In addition, after the work floor assembly 15 is deployed, a locking piece 37 b is provided at the other end of the support 37 opposite to the one end. The locking piece 37b is detachably locked to the locking portion 31a. Therefore, the support body 37 is interposed between the base portion 32 and the support column 31.
　また、図３に示すように、ベース部３２の一面には、床部材３４が載置される。床部材３４は、矩形をなす平板状に形成されている。床部材３４の周縁部には、幅木３４ａが形成されている。幅木３４ａは、床部材３４の周縁部から上下方向の上方に向けて略垂直に屈曲している。 Further, as shown in FIG. 3, a floor member 34 is placed on one surface of the base portion 32. The floor member 34 is formed in a rectangular flat plate shape. A skirting board 34 a is formed on the peripheral edge of the floor member 34. The skirting board 34a is bent substantially vertically from the peripheral edge of the floor member 34 upward in the vertical direction.
　なお、本例では、幅木３４ａを床部材３４に設けた例を説明したが、これに限定されるものではなく、ベース部３２に幅木を設けてもよく、あるいは幅木をベース部３２や床部材３４とは別部材として構成してもよい。 In this example, the example in which the baseboard 34a is provided on the floor member 34 has been described. However, the present invention is not limited to this. The floor member 34 may be configured as a separate member.
　さらに、ベース部３２における床部材３４が設けられた一面とは反対側の他面には、補強部材５１が固定されている。この補強部材５１によりベース部３２の強度を高めている。 Furthermore, a reinforcing member 51 is fixed to the other surface of the base portion 32 opposite to the one surface on which the floor member 34 is provided. This reinforcing member 51 increases the strength of the base portion 32.
　ベース部３２には、落下防止冊１６が着脱可能に取り付けられる。落下防止冊１６は、４つの脚部４１と、手摺４２と、固定部材４３とを有している。４つの脚部４１は、ベース部３２の四隅に固定部材４３を介して固定される。また、脚部４１の上下方向の上端部には、手摺４２が固定ねじ６４を介して取り付けられる。手摺４２は、作業者が出入りする建築構造物のホール３０１側（図４参照）の一辺を除く三辺に取り付けられる。この手摺４２により、保守点検時の作業者の安全が確保される。 The fall prevention book 16 is detachably attached to the base portion 32. The fall prevention book 16 has four leg portions 41, a handrail 42, and a fixing member 43. The four leg portions 41 are fixed to the four corners of the base portion 32 via fixing members 43. A handrail 42 is attached to the upper end portion of the leg portion 41 in the vertical direction via a fixing screw 64. The handrail 42 is attached to three sides excluding one side of the hall 301 side (see FIG. 4) of the building structure where an operator enters and exits. The handrail 42 ensures the safety of the operator during maintenance inspection.
　なお、作業床組立体１５及び落下防止冊１６の構成は、上述した例に限定されるものではなく、その他各種の構成を適用できるものである。例えば、落下防止冊１６の手摺４２としては、チェーンやロープ等を用いてもよい。さらに、作業床組立体１５のベース部３２や床部材３４を複数の部材で構成したり、ベース部３２を二つ折り可能に構成したりしてもよい。 The configurations of the work floor assembly 15 and the fall prevention book 16 are not limited to the above-described examples, and other various configurations can be applied. For example, a chain, a rope, or the like may be used as the handrail 42 of the fall prevention booklet 16. Further, the base portion 32 and the floor member 34 of the work floor assembly 15 may be configured by a plurality of members, or the base portion 32 may be configured to be folded in two.
２．エレベーター用作業台の設置作業例
　次に、上述した構成を有する作業台１０の設置作業の一例について説明する。
　まず、図１に示すように、メンテナンス対象機器１５０の近傍まで乗りかご１２０を上昇させる。これにより、図３及び図４に示すように、停止装置１３０におけるロック部材１３２の一端部は、かご側ガイドレール２０１に設けた規制孔２０１ａを臨む。そして、ロック部材１３２がその軸方向に沿って摺動することで、ロック部材１３２の一端部は、規制孔２０１ａに挿脱可能に挿入される。その結果、乗りかご１２０の昇降移動が停止装置１３０によって機械的に規制することができる。 2. Next, an example of the installation work of the work table 10 having the above-described configuration will be described.
First, as shown in FIG. 1, the car 120 is raised to the vicinity of the maintenance target device 150. As a result, as shown in FIGS. 3 and 4, one end of the locking member 132 in the stopping device 130 faces the regulation hole 201 a provided in the car-side guide rail 201. Then, as the lock member 132 slides along the axial direction, one end of the lock member 132 is removably inserted into the restriction hole 201a. As a result, the raising / lowering movement of the car 120 can be mechanically restricted by the stop device 130.
　さらに、ロック部材１３２が摺動移動して規制孔２０１ａに挿入された際に、スイッチ１３６は、不図示の制御部に停止信号を出力する。これにより、制御部は、巻上機の駆動を停止させる。その結果、乗りかご１２０の昇降移動が、停止装置１３０によって電気的に規制される。これにより、乗りかご１２０が保守点検時に作用者の意図に反して昇降移動することを防止することができ、保守点検時の安全を確保することができる。 Furthermore, when the lock member 132 slides and is inserted into the restriction hole 201a, the switch 136 outputs a stop signal to a control unit (not shown). Thereby, a control part stops the drive of a winding machine. As a result, the raising / lowering movement of the car 120 is electrically restricted by the stopping device 130. Thereby, it is possible to prevent the car 120 from moving up and down against the intention of the operator during maintenance and inspection, and to ensure safety during maintenance and inspection.
　次に、作業台１０の第１連結部材１１と第２連結部材１２の固定面部２１を上梁１２１の上面部１２１ａに載置する。このとき、第１連結部材１１の規制板２３が、収容部材１３１の収容凹部１３１ａに挿入される。そして、規制板２３は、ロック部材１３２の他端部と対向する。次に、第１連結部材１１及び第２連結部材１２を固定ボルト６１によって上梁１２１に締結固定する。このように、乗りかご１２０において比較的強度が高い上梁１２１に第１連結部材１１及び第２連結部材１２を固定することで、作業台１０を安定して設置することができる。 Next, the fixed surface portions 21 of the first connecting member 11 and the second connecting member 12 of the work table 10 are placed on the upper surface portion 121 a of the upper beam 121. At this time, the restriction plate 23 of the first connecting member 11 is inserted into the housing recess 131 a of the housing member 131. The restricting plate 23 faces the other end of the lock member 132. Next, the first connecting member 11 and the second connecting member 12 are fastened and fixed to the upper beam 121 by the fixing bolt 61. In this way, the work table 10 can be stably installed by fixing the first connecting member 11 and the second connecting member 12 to the upper beam 121 having relatively high strength in the car 120.
　なお、図２に示すように、停止装置１３０のロック部材１３２が規制孔２０１ａに挿入されていない場合、ロック部材１３２の他端部は、収容凹部１３１ａに収容されている。そのため、第１連結部材１１の規制板２３とロック部材１３２が干渉するため、第１連結部材１１を上梁１２１に固定することはできない。 In addition, as shown in FIG. 2, when the lock member 132 of the stop device 130 is not inserted into the restriction hole 201a, the other end of the lock member 132 is accommodated in the accommodation recess 131a. For this reason, the restriction plate 23 of the first connecting member 11 and the lock member 132 interfere with each other, so that the first connecting member 11 cannot be fixed to the upper beam 121.
　すなわち、停止装置１３０が作動して安全が確保されていない状態では、第１連結部材１１を固定することができない。そして、図３及び図４に示すように、停止装置１３０が作動して安全が確保された状態でのみ、第１連結部材１１が固定可能となり、作業台１０を設置することができる。 In other words, the first connecting member 11 cannot be fixed in a state where the stop device 130 is activated and safety is not ensured. As shown in FIGS. 3 and 4, the first connecting member 11 can be fixed and the worktable 10 can be installed only when the stop device 130 is activated and safety is ensured.
　また、第１連結部材１１を上梁１２１に載置した際に、保護カバー２４は、停止装置１３０のスイッチ１３６の上下方向の上方を覆う。これにより、保守点検時に作業者が誤ってスイッチ１３６を踏むことを保護カバー２４によって防ぐことができ、スイッチ１３６の破損を防止できる。 Further, when the first connecting member 11 is placed on the upper beam 121, the protective cover 24 covers the upper portion of the switch 136 of the stop device 130 in the vertical direction. Thus, the protective cover 24 can prevent the operator from stepping on the switch 136 by mistake during maintenance inspection, and the switch 136 can be prevented from being damaged.
　次に、作業床組立体１５を展開させて、支持体３７の係止片３７ｂを支持柱３１の係止部に係止させる。これにより、支持体３７は、ベース部３２と支持柱３１の間に介在されるため、ベース部３２が回動軸３６を中心に支持柱３１に向けて回動することを防ぐことができる。その結果、保守点検時に作業者の意図に反して作業床組立体１５が折り畳まれることを防ぐことができ、作業の安全性を高めることができる。 Next, the work floor assembly 15 is expanded and the locking piece 37b of the support 37 is locked to the locking portion of the support column 31. Thereby, since the support body 37 is interposed between the base part 32 and the support pillar 31, it can prevent that the base part 32 rotates toward the support pillar 31 centering on the rotating shaft 36. FIG. As a result, it is possible to prevent the work floor assembly 15 from being folded against the operator's intention during maintenance and inspection, and to improve work safety.
　そして、２つの支持柱３１、３１を支持ボルト６２によって第１連結部材１１と第２連結部材１２に締結固定する。また、図５に示すように、支持柱３１の下端部を上梁１２１の側面部１２１ｃに固定ボルト６３を介して締結固定する。 Then, the two support columns 31 and 31 are fastened and fixed to the first connecting member 11 and the second connecting member 12 by the support bolts 62. Further, as shown in FIG. 5, the lower end portion of the support column 31 is fastened and fixed to the side surface portion 121 c of the upper beam 121 via a fixing bolt 63.
　なお、支持体３７の係止作業は、２つの支持柱３１、３１を第１連結部材１１、第２連結部材１２及び上梁１２１に固定した後に行ってもよい。 In addition, you may perform the latching operation | work of the support body 37, after fixing the two support pillars 31 and 31 to the 1st connection member 11, the 2nd connection member 12, and the upper beam 121. FIG.
　次に、ベース部３２の一面に床部材３４を載置して取り付ける。また、ベース部３２の四隅に、落下防止冊１６の４つの脚部４１を立設させる。そして、固定部材４３によって脚部４１をベース部３２に固定する。次に、脚部４１の上端部に手摺４２を、固定ねじ６４を用いて取り付ける。これにより、作業台１０の設置作業が完了する。 Next, the floor member 34 is mounted on one surface of the base portion 32 and attached. Further, the four leg portions 41 of the fall prevention book 16 are erected at the four corners of the base portion 32. Then, the leg portion 41 is fixed to the base portion 32 by the fixing member 43. Next, the handrail 42 is attached to the upper end portion of the leg portion 41 using a fixing screw 64. Thereby, the installation work of the work table 10 is completed.
　また、規制板２３がロック部材１３２の他端部と対向するため、ロック部材１３２における軸方向の他端部側への移動が規制される。そのため、第１連結部材１１が上梁１２１に載置されている状態では、ロック部材１３２を規制孔２０１ａから抜き出すことができない。すなわち、規制板２３は、停止装置１３０における乗りかご１２０の昇降移動の規制を解除する方向への動作を規制する。その結果、保守点検時では、停止装置１３０における乗りかご１２０の昇降移動の規制が解除されることがないため、保守点検時の安全性を向上させることができる。 Further, since the restricting plate 23 faces the other end of the lock member 132, movement of the lock member 132 toward the other end in the axial direction is restricted. Therefore, in a state where the first connecting member 11 is placed on the upper beam 121, the lock member 132 cannot be extracted from the restriction hole 201a. In other words, the restricting plate 23 restricts the movement of the stopping device 130 in the direction to release the restriction of the lifting / lowering movement of the car 120. As a result, at the time of maintenance inspection, since the restriction of the lifting and lowering movement of the car 120 in the stopping device 130 is not released, the safety at the time of maintenance inspection can be improved.
　さらに、停止装置１３０は、第１連結部材１１が上梁１２１から取り外されて、規制板２３が収容凹部１３１ａから抜け出るまで、乗りかご１２０の昇降移動の規制を解除することができない。このように、作業台１０が乗りかご１２０から取り外されるまで、停止装置１３０が解除されないため、作業台１０の取り外し作業も安全に行うことができる。 Furthermore, the stopping device 130 cannot release the restriction of the elevator car 120 until the first connecting member 11 is removed from the upper beam 121 and the restricting plate 23 comes out of the housing recess 131a. Thus, since the stop device 130 is not released until the work table 10 is removed from the car 120, the work for removing the work table 10 can be performed safely.
　上述したように、作業台１０は、停止装置１３０が作動するまで乗りかご１２０の設置することができない。その結果、保守点検時以外の通常運転時では、作業台１０を乗りかご１２０に設置することができないため、乗りかご１２０の軽量化を図ることができる。 As described above, the work platform 10 cannot install the car 120 until the stop device 130 is activated. As a result, since the work table 10 cannot be installed on the car 120 during normal operation other than during maintenance and inspection, the weight of the car 120 can be reduced.
　なお、本発明は上述しかつ図面に示した実施の形態に限定されるものではなく、特許請求の範囲に記載した発明の要旨を逸脱しない範囲内で種々の変形実施が可能である。上述した実施の形態例では、第１連結部材１１にのみ規制板２３及び保護カバー２４を設けた例を説明したが、これに限定されるものではなく、第２連結部材１２にも規制板２３及び保護カバー２４を設けてもよい。 The present invention is not limited to the embodiment described above and shown in the drawings, and various modifications can be made without departing from the scope of the invention described in the claims. In the embodiment described above, the example in which the restriction plate 23 and the protective cover 24 are provided only on the first connecting member 11 has been described. However, the present invention is not limited to this, and the restriction plate 23 is also provided on the second connecting member 12. Further, a protective cover 24 may be provided.
　例えば、メンテナンス対象機器１５０が乗りかご１２０における上梁１２１の長手方向の他端部側の昇降路１１０に設置されている場合、第２連結部材１２は、上梁１２１の長手方向の他端部に固定される。そして、第２連結部材１２に設けた規制板２３が上梁１２１の長手方向の他端部に配置された停止装置の収容凹部に挿入される。 For example, when the maintenance target device 150 is installed in the hoistway 110 on the other end side in the longitudinal direction of the upper beam 121 in the car 120, the second connecting member 12 is connected to the other end portion in the longitudinal direction of the upper beam 121. Fixed to. Then, the restriction plate 23 provided on the second connecting member 12 is inserted into the accommodation recess of the stopping device disposed at the other end portion of the upper beam 121 in the longitudinal direction.
　また、これに限定されるものではない。ロック部材１３２が挿脱可能に挿入される規制孔２０１ａは、かご側ガイドレール２０１に設けられるものに限定されるものではない。昇降路１１０内に設けられたかご側ガイドレール２０１とは異なる部材、例えば、レールブラケットや、釣合おもりを摺動可能に支持するおもり側ガイドレールに規制孔を形成してもよい。 Also, it is not limited to this. The restriction hole 201a into which the lock member 132 is removably inserted is not limited to that provided in the car side guide rail 201. A restriction hole may be formed in a member different from the car-side guide rail 201 provided in the hoistway 110, for example, a rail bracket or a weight-side guide rail that slidably supports a counterweight.
　なお、本明細書において、「平行」及び「直交」等の単語を使用したが、これらは厳密な「平行」及び「直交」のみを意味するものではなく、「平行」及び「直交」を含み、さらにその機能を発揮し得る範囲にある、「略平行」や「略直交」の状態であってもよい。 In this specification, words such as “parallel” and “orthogonal” are used, but these do not mean only strict “parallel” and “orthogonal”, but include “parallel” and “orthogonal”. Further, it may be in a state of “substantially parallel” or “substantially orthogonal” within a range where the function can be exhibited.
