Description

乗りかご及びエレベーターCar and elevator
　本発明は、かご枠を備えた乗りかご、及びその乗りかごを備えたエレベーターに関する。 The present invention relates to a car equipped with a car frame and an elevator equipped with the car.
　従来、エレベーターの乗りかごは、かご室と、かご室を支持するかご枠を備えている。かご室は、床と、天井と、側板とを有している。かご枠は、かご室の外側に配置され、床、天井、側板を囲む四角形の枠状に形成されている。 Conventionally, the elevator car is equipped with a car room and a car frame that supports the car room. The car room has a floor, a ceiling, and side plates. The car frame is arranged outside the car room and is formed in a rectangular frame shape surrounding the floor, ceiling, and side plates.
　特許文献１には、乗りかごの組立方法に関する技術が記載されている。特許文献１に記載された乗りかごの組立方法では、まず、中間側板を除く他の側板を天井板、床枠および隣接側板に固定する。この時、中間側板を除く他の側板と床材との固定部には、予め所定寸法のライナが取付ける。その後、中間側板を嵌め込み、中間側板と床枠間に生じた間隙にライナを挿入する。中間側板は、その長さ寸法が天井板から床枠までの長さ寸法より所定寸法短く設定されている。これにより、中間側板の嵌め込み時に天井板に干渉することがない。 Patent Document 1 describes a technique relating to a method of assembling a car. In the car assembly method described in Patent Document 1, first, the side plates other than the intermediate side plate are fixed to the ceiling plate, the floor frame, and the adjacent side plate. At this time, a liner having a predetermined size is attached in advance to the fixing portion between the floor material and the other side plates except the intermediate side plate. After that, the intermediate side plate is fitted, and the liner is inserted into the gap formed between the intermediate side plate and the floor frame. The length of the intermediate side plate is set shorter than the length from the ceiling plate to the floor frame. As a result, it does not interfere with the ceiling plate when the intermediate side plate is fitted.

　ところで、特許文献１に記載されているような乗りかごは、側板を天井板に固定する際に、天井と側板が干渉して天井の意匠を傷つける恐れがある。そこで、側板を天井板に固定する際は、天井を上方に移動させることがある。しかし、天井を上方に移動させるには、天井の上方に位置するかご枠の上枠を、天井と干渉しない位置まで上昇させる必要がある。したがって、かご枠の上枠を上昇させる（嵩上げする）作業を容易にすることが望まれている。 By the way, in a car as described in Patent Document 1, when the side plate is fixed to the ceiling plate, the ceiling and the side plate may interfere with each other and damage the design of the ceiling. Therefore, when fixing the side plate to the ceiling plate, the ceiling may be moved upward. However, in order to move the ceiling upward, it is necessary to raise the upper frame of the car frame located above the ceiling to a position where it does not interfere with the ceiling. Therefore, it is desired to facilitate the work of raising (raising) the upper frame of the car frame.
　本目的は、上記の問題点を考慮し、かご枠の上枠を上昇させる（嵩上げする）作業を容易にすることができる乗りかご、及びその乗りかごを備えたエレベーターを提供することにある。 The purpose of this purpose is to provide a car that can facilitate the work of raising (raising) the upper frame of the car frame in consideration of the above problems, and an elevator equipped with the car.
　上記課題を解決し、本目的を達成するため、本発明の乗りかごは、側板及び天井板を有するかご室と、前記かご室を支持するかご枠と、嵩上げ部材とを備える。かご枠は、かご室の側板に対向するたて枠と、天井板に対向する上枠とを有する。嵩上げ部材は、たて枠と上枠にねじを用いて接続される。また、嵩上げ部材は、たて枠に接続するために用いるたて枠用ねじが貫通するたて枠用ねじ貫通孔と、上枠に接続するために用いる上枠用ねじが貫通する上枠用ねじ貫通孔を有する。そして、たて枠用ねじ貫通孔は、上下方向に延びる縦長に形成されている。
　また、本発明のエレベーターは、昇降路内を昇降動作する上記乗りかごを備えている。 In order to solve the above problems and achieve the present object, the car of the present invention includes a car chamber having a side plate and a ceiling plate, a car frame for supporting the car chamber, and a raising member. The car frame has a vertical frame facing the side plate of the car chamber and an upper frame facing the ceiling plate. The raising member is connected to the vertical frame and the upper frame using screws. Further, the raising member is for a vertical frame screw through hole through which a vertical frame screw used for connecting to a vertical frame and an upper frame through which an upper frame screw used for connecting to the upper frame penetrates. Has a thread through hole. The vertical frame screw through hole is formed in a vertically long shape extending in the vertical direction.

　以下、実施の形態例にかかるエレベーターにいて、図１～図９を参照して説明する。なお、各図において共通の部材には、同一の符号を付している。 Hereinafter, the elevator according to the embodiment will be described with reference to FIGS. 1 to 9. The common members in each figure are designated by the same reference numerals.
１．エレベーターの構成
　まず、本発明の一実施形態（以下、「本例」という。）に係るエレベーターの構成について、図１を参照して説明する。
　図１は、本例のエレベーターの構成例を示す概略構成図である。 1. 1. Elevator Configuration First, an elevator configuration according to an embodiment of the present invention (hereinafter referred to as “this example”) will be described with reference to FIG.
FIG. 1 is a schematic configuration diagram showing a configuration example of the elevator of this example.
　図１に示すように、本例のエレベーター１は、建物構造物内に形成された昇降路１１０内を昇降動作する。エレベーター１は、人や荷物を載せる乗りかご１２０と、ロープ１３０と、釣合錘１４０と、巻上機１００とを備える。昇降路１１０は、建築構造物内に形成され、その頂部には機械室１６０が設けられている。 As shown in FIG. 1, the elevator 1 of this example moves up and down in a hoistway 110 formed in a building structure. The elevator 1 includes a car 120 for carrying people and luggage, a rope 130, a balance weight 140, and a hoisting machine 100. The hoistway 110 is formed in a building structure, and a machine room 160 is provided at the top thereof.
　巻上機１００は、機械室１６０に配置され、ロープ１３０を巻き掛けることにより乗りかご１２０を昇降させる。また、巻上機１００の近傍には、ロープ１３０が装架される反らせ車１５０が設けられている。 The hoisting machine 100 is arranged in the machine room 160, and the car 120 is raised and lowered by winding the rope 130. Further, in the vicinity of the hoisting machine 100, a warp wheel 150 on which the rope 130 is mounted is provided.
　釣合錘１４０は、乗りかご１２０における無積載時の質量とほぼ同じ質量に設定されている。そのため、乗りかご１２０内に物や人が積載されていない無積載時では、乗りかご１２０側と釣合錘１４０側のロープ１３０の張力比は、１となる。これにより、無積載時における巻上機１００の出力を低く抑えることが可能である。 The balance weight 140 is set to have substantially the same mass as the mass of the car 120 when it is not loaded. Therefore, when no object or person is loaded in the car 120, the tension ratio of the rope 130 on the car 120 side and the balance weight 140 side is 1. As a result, it is possible to keep the output of the hoisting machine 100 low when the load is not loaded.
　乗りかご１２０は、ロープ１３０を介して、釣合錘１４０と連結され、昇降路１１０内を昇降する。 The car 120 is connected to the balance weight 140 via the rope 130 and moves up and down in the hoistway 110.
［乗りかご］
　次に、図２及び図３を参照して乗りかご１２０の構成について説明する。
　図２は、乗りかご１２０の外観斜視図である。図３は、乗りかご１２０の上枠とたて枠の一部を示す斜視図である。 [Cargo]
Next, the configuration of the car 120 will be described with reference to FIGS. 2 and 3.
FIG. 2 is an external perspective view of the car 120. FIG. 3 is a perspective view showing a part of the upper frame and the vertical frame of the car 120.
　図２に示すように、乗りかご１２０は、かご室１２１と、かご枠１２２と、不図示のドアユニットとを有している。かご室１２１は、中空の略直方体状に形成されている。かご室１２１の一面には、開口部である出入り口が設けられている。かご室１２１の内部空間には、出入り口から人や荷物が出入りする。かご室１２１の出入り口には、ドアユニットが設置されている。ドアユニットは、かご室１２１の出入り口を開閉可能に構成されている。 As shown in FIG. 2, the car 120 has a car room 121, a car frame 122, and a door unit (not shown). The car chamber 121 is formed in a hollow substantially rectangular parallelepiped shape. An entrance / exit, which is an opening, is provided on one surface of the car chamber 121. People and luggage enter and exit the internal space of the car room 121 from the doorway. A door unit is installed at the doorway of the car room 121. The door unit is configured to be able to open and close the doorway of the car chamber 121.
　かご室１２１は、かご床１２５と、４つの側板１２６Ａ～１２６Ｄと、天井板１２７とを備えている。かご床１２５は、略矩形状に形成されている。かご床１２５の周囲には、４つの側板１２６Ａ～１２６Ｄが配置されている。天井板１２７は、かご床１２５に対して上下方向に対向している。天井板１２７の周囲には、４つの側板１２６Ａ～１２６Ｄが配置されている。 The car room 121 includes a car floor 125, four side plates 126A to 126D, and a ceiling plate 127. The car floor 125 is formed in a substantially rectangular shape. Four side plates 126A to 126D are arranged around the car floor 125. The ceiling plate 127 faces the car floor 125 in the vertical direction. Four side plates 126A to 126D are arranged around the ceiling plate 127.
　側板１２６Ａには、上述した出入り口が形成されている。側板１２６Ａは、側板１２６Ｂと対向している。また、側板１２６Ｃは、側板１２６Ｄと対向している。以下、側板１２６Ａと側板１２６Ｂが対向する方向を前後方向とし、側板１２６Ｃと側板１２６Ｄが対向する方向を左右方向とする。 The above-mentioned doorway is formed on the side plate 126A. The side plate 126A faces the side plate 126B. Further, the side plate 126C faces the side plate 126D. Hereinafter, the direction in which the side plates 126A and the side plates 126B face each other is defined as the front-rear direction, and the direction in which the side plates 126C and the side plates 126D face each other is defined as the left-right direction.
　かご枠１２２は、かご床１２５、側板１２６Ｃ，１２６Ｄ、天井板１２７を囲む矩形の枠状に形成されている。かご枠１２２は、かご床１２５を支持する下枠２１と、側板１２６Ｃ，１２６Ｄにそれぞれ対向するたて枠２２Ａ，２２Ｂと、天井板１２７に対向する上枠２３とを有する。 The car frame 122 is formed in a rectangular frame shape surrounding the car floor 125, side plates 126C, 126D, and ceiling plate 127. The car frame 122 has a lower frame 21 that supports the car floor 125, vertical frames 22A and 22B that face the side plates 126C and 126D, respectively, and an upper frame 23 that faces the ceiling plate 127.
　たて枠２２Ａ，２２Ｂは、上下方向に延びている。たて枠２２Ａ，２２Ｂの上下方向に直交する断面形状は、略Ｃ型である。たて枠２２Ａ，２２Ｂは、昇降路１１０（図１参照）に設置された２つのガイドレール１７０（図２では１つを省略している）にそれぞれ対向している。２つのガイドレール１７０は、上下方向に延びている。２つのガイドレール１７０は、乗りかご２を上下方向（昇降方向）に案内する。 The vertical frames 22A and 22B extend in the vertical direction. The cross-sectional shapes of the vertical frames 22A and 22B orthogonal to the vertical direction are substantially C-shaped. The vertical frames 22A and 22B face two guide rails 170 (one is omitted in FIG. 2) installed in the hoistway 110 (see FIG. 1), respectively. The two guide rails 170 extend in the vertical direction. The two guide rails 170 guide the car 2 in the vertical direction (elevating direction).
　たて枠２２Ａ，２２Ｂの上部は、上枠２３に後述する接続部材３７を用いて接続されている。また、たて枠２２Ａ，２２Ｂと上枠２３には、４つの嵩上げ部材３１がねじを用いて接続されている。 The upper portions of the vertical frames 22A and 22B are connected to the upper frame 23 by using a connecting member 37 described later. Further, four raising members 31 are connected to the vertical frames 22A and 22B and the upper frame 23 by using screws.
　上枠２３は、左右方向に延びている。上枠２３の左右方向に直交する断面形状は、略Ｃ型である。上枠２３には、２つのスライダ２５（図２では１つを省略している）が固定されている。２つのスライダ２５は、上枠２３の長手方向における両端部に配置されている。２つのスライダ２５は、２つのガイドレール１７０にそれぞれ摺動可能に係合する。これにより、乗りかご１２０は、２つのガイドレール１７０に案内されて昇降路１１０（図１参照）内を上下方向に移動する。 The upper frame 23 extends in the left-right direction. The cross-sectional shape of the upper frame 23 orthogonal to the left-right direction is substantially C-shaped. Two sliders 25 (one is omitted in FIG. 2) are fixed to the upper frame 23. The two sliders 25 are arranged at both ends of the upper frame 23 in the longitudinal direction. The two sliders 25 are slidably engaged with the two guide rails 170, respectively. As a result, the car 120 is guided by the two guide rails 170 and moves up and down in the hoistway 110 (see FIG. 1).
　図３に示すように、たて枠２２Ａ，２２Ｂは、ベース片２２１と、ベース片２２１に連続する側片２２２，２２３を有している。ベース片２２１は、上下方向に長い長方形に形成されている。ベース片２２１の平面は、左右方向に直交する。ベース片２２１の一方の平面は、かご室１２１の側板１２６Ｃ（１２６Ｄ）に対向する。ベース片２２１の上部には、２つの接続部材用貫通孔２２１ａが設けられている。２つの接続部材用貫通孔２２１ａには、接続部材用ねじ（ボルト）５５がそれぞれ貫通する（図９参照）。 As shown in FIG. 3, the vertical frames 22A and 22B have a base piece 221 and side pieces 222 and 223 continuous with the base piece 221. The base piece 221 is formed in a rectangular shape that is long in the vertical direction. The plane of the base piece 221 is orthogonal to the left-right direction. One plane of the base piece 221 faces the side plate 126C (126D) of the car chamber 121. Two through holes 221a for connecting members are provided in the upper part of the base piece 221. The connection member screw (bolt) 55 penetrates through the two connection member through holes 221a (see FIG. 9).
　側片２２２，２２３は、ベース片２２１の長辺から略垂直に立ち上がっている。側片２２２，２２３は、上下方向に長い長方形に形成されている。側片２２２，２２３の平面は、前後方向に直交する。側片２２２，２２３は、前後方向で対向している。側片２２２，２２３の上部には、それぞれ２つの嵩上げ部材用貫通孔２２４が設けられている。２つの嵩上げ部材用貫通孔２２４には、たて枠用ねじ（ボルト）５１が貫通する（図６参照）。 The side pieces 222 and 223 stand up substantially vertically from the long side of the base piece 221. The side pieces 222 and 223 are formed in a rectangular shape that is long in the vertical direction. The planes of the side pieces 222 and 223 are orthogonal to each other in the front-rear direction. The side pieces 222 and 223 face each other in the front-rear direction. Two through holes 224 for raising members are provided on the upper portions of the side pieces 222 and 223, respectively. Vertical frame screws (bolts) 51 penetrate through the two raising member through holes 224 (see FIG. 6).
　上枠２３は、ベース片２３１と、ベース片２３１に連続する側片２３２，２３３を有している。ベース片２３１は、左右方向に長い長方形に形成されている。ベース片２３１の平面は、上下方向に直交する。ベース片２３１の一方の平面（下面）は、かご室１２１の天井板１２７に対向する。ベース片２３１の左右方向の両端部には、２つの接続部材用貫通孔２３１ａが設けられている。２つの接続部材用貫通孔２３１ａには、接続部材用ねじ（ボルト）５５が貫通する（図９参照）。 The upper frame 23 has a base piece 231 and side pieces 232 and 233 continuous with the base piece 231. The base piece 231 is formed in a rectangular shape that is long in the left-right direction. The plane of the base piece 231 is orthogonal to the vertical direction. One flat surface (lower surface) of the base piece 231 faces the ceiling plate 127 of the cab 121. Two through holes 231a for connecting members are provided at both ends of the base piece 231 in the left-right direction. The connection member screw (bolt) 55 penetrates through the two connection member through holes 231a (see FIG. 9).
　側片２３２，２３３は、ベース片２３１の長辺から略垂直に立ち上がっている。側片２３２，２３３は、左右方向に長い長方形に形成されている。側片２３２，２３３の平面は、前後方向に直交する。側片２３２，２３３は、前後方向で対向している。側片２３２，２３３の左右方向の両端部には、それぞれ２つの嵩上げ部材用貫通孔２３４が設けられている。２つの嵩上げ部材用貫通孔２３４には、上枠用ねじ（ボルト）５３が貫通する（図６参照）。 The side pieces 232 and 233 stand up substantially vertically from the long side of the base piece 231. The side pieces 232 and 233 are formed in a rectangular shape that is long in the left-right direction. The planes of the side pieces 232 and 233 are orthogonal to each other in the front-rear direction. The side pieces 232 and 233 face each other in the front-rear direction. Two through holes 234 for raising members are provided at both ends of the side pieces 223 and 233 in the left-right direction. Upper frame screws (bolts) 53 penetrate through the two raising member through holes 234 (see FIG. 6).
［嵩上げ部材］
　次に、図４及び図５を参照して嵩上げ部材３１の構成について説明する。
　図４は、嵩上げ部材３１を外面側から見た斜視図である。図５は、嵩上げ部材３１を内面側から見た斜視図である。 [Raising member]
Next, the configuration of the raising member 31 will be described with reference to FIGS. 4 and 5.
FIG. 4 is a perspective view of the raising member 31 as viewed from the outer surface side. FIG. 5 is a perspective view of the raising member 31 as viewed from the inner surface side.
　図４及び図５に示すように、嵩上げ部材３１は、平面形状が略Ｌ字状の板体からなる。嵩上げ部材３１は、たて枠２２Ａ（２２Ｂ）に接続されるたて枠接続部３２と、上枠２３に接続される上枠接続部３３とを有する。たて枠接続部３２は、上下方向に延びる長方形に形成されている。たて枠接続部３２には、たて枠用ねじ５１が貫通するたて枠用ねじ貫通孔３２ａが設けられている。たて枠用ねじ貫通孔３２ａは、上下方向に延びる縦長に形成されている。これにより、嵩上げ部材３１の上下方向の接続位置を容易に変更することができる。 As shown in FIGS. 4 and 5, the raising member 31 is made of a plate having a substantially L-shaped plane shape. The raising member 31 has a vertical frame connecting portion 32 connected to the vertical frame 22A (22B) and an upper frame connecting portion 33 connected to the upper frame 23. The vertical frame connecting portion 32 is formed in a rectangular shape extending in the vertical direction. The vertical frame connecting portion 32 is provided with a vertical frame screw through hole 32a through which the vertical frame screw 51 penetrates. The vertical frame screw through hole 32a is formed in a vertically long shape extending in the vertical direction. As a result, the connection position of the raising member 31 in the vertical direction can be easily changed.
　上枠接続部３３は、たて枠接続部３２の上辺に連続している。上枠接続部３３は、左右方向に延びる長方形に形成されたねじ貫通片３４と、ねじ貫通片に連続する支持片３５を有する。ねじ貫通片３４は、上枠２３の側片２３２（２３３）に当接する。ねじ貫通片３４には、２つの上枠用ねじ貫通孔３４ａと、吊り下げ用孔３４ｂが設けられている。 The upper frame connecting portion 33 is continuous with the upper side of the vertical frame connecting portion 32. The upper frame connecting portion 33 has a screw penetrating piece 34 formed in a rectangular shape extending in the left-right direction, and a support piece 35 continuous with the screw penetrating piece. The screw penetrating piece 34 abuts on the side piece 232 (233) of the upper frame 23. The screw through piece 34 is provided with two upper frame screw through holes 34a and a hanging hole 34b.
　２つの上枠用ねじ貫通孔３４ａは、左右方向に適当な間隔を空けて配置されている。２つの上枠用ねじ貫通孔３４ａには、上枠用ねじ５３が貫通する。吊り下げ用孔３４ｂは、ねじ貫通片３４の上部におけるたて枠接続部３２側の角部に配置されている。この吊り下げ用孔３４ｂは、嵩上げ部材３１を吊り下げる際に用いられる。 The two upper frame screw through holes 34a are arranged at appropriate intervals in the left-right direction. The upper frame screw 53 penetrates through the two upper frame screw through holes 34a. The hanging hole 34b is arranged at a corner portion on the vertical frame connecting portion 32 side in the upper part of the screw penetrating piece 34. The suspending hole 34b is used when suspending the raising member 31.
　支持片３５は、折り曲げ加工により形成されている。支持片３５は、ねじ貫通片３４の下辺から略垂直に突出している。支持片３５は、上枠２３のベース片２３１の一方の平面（下面）に当接する。これにより、支持片３５は、上枠２３の下部を支える。その結果、上枠用ねじ５３に上枠２３の荷重が集中しないようにすることができる。 The support piece 35 is formed by bending. The support piece 35 projects substantially vertically from the lower side of the screw penetration piece 34. The support piece 35 abuts on one flat surface (lower surface) of the base piece 231 of the upper frame 23. As a result, the support piece 35 supports the lower part of the upper frame 23. As a result, the load of the upper frame 23 can be prevented from being concentrated on the upper frame screw 53.
［上枠の嵩上げ作業］
　次に、上枠２３の嵩上げ作業について、図６～図９を参照して説明する。
　図６は、嵩上げ部材３１をかご枠１２２に接続した状態を示す斜視図である。図７は、上枠２３を嵩上げする前の状態を示す斜視図である。図８は、上枠２３を嵩上げした状態を示す斜視図である。図９は、上枠２３とたて枠２２Ａを接続部材３７によって接続した状態を示す斜視図である。 [Raising the upper frame]
Next, the raising work of the upper frame 23 will be described with reference to FIGS. 6 to 9.
FIG. 6 is a perspective view showing a state in which the raising member 31 is connected to the car frame 122. FIG. 7 is a perspective view showing a state before raising the upper frame 23. FIG. 8 is a perspective view showing a state in which the upper frame 23 is raised. FIG. 9 is a perspective view showing a state in which the upper frame 23 and the vertical frame 22A are connected by the connecting member 37.
　エレベーター１の乗りかご１２０を建物構造物内に据え付ける場合は、まず、ガイドレール１７０に対してかご枠１２２のたて枠２２Ａ，２２Ｂの位置決めを行う。次に、上枠２３及び下枠２１をたて枠２２Ａ，２２Ｂに接続する。上枠２３をたて枠２２Ａ（２２Ｂ）に接続する場合は、４つの嵩上げ部材３１を用いる。 When installing the car 120 of the elevator 1 in the building structure, first, the vertical frames 22A and 22B of the car frame 122 are positioned with respect to the guide rail 170. Next, the upper frame 23 and the lower frame 21 are vertically connected to the frames 22A and 22B. When the upper frame 23 is connected to the vertical frame 22A (22B), four raising members 31 are used.
　図６に示すように、上枠２３とたて枠２２Ａ（２２Ｂ）の接続作業では、嵩上げ部材３１のたて枠用ねじ貫通孔３２ａ及びたて枠２２Ａ（２２Ｂ）の２つの嵩上げ部材用貫通孔２２４に、２つのたて枠用ねじ（ボルト）５１を貫通させてナット５２を螺合させる。これにより、嵩上げ部材３１とたて枠２２Ａ（２２Ｂ）が接続される。このとき、上方に位置するたて枠用ねじ５１は、たて枠用ねじ貫通孔３２ａの上端に接触する。下方に位置するたて枠用ねじ５１は、たて枠用ねじ貫通孔３２ａの中間部に位置する。 As shown in FIG. 6, in the connection work between the upper frame 23 and the vertical frame 22A (22B), the vertical frame screw through hole 32a and the vertical frame 22A (22B) of the raising member 31 penetrate through the two raising members. Two vertical frame screws (bolts) 51 are passed through the holes 224 to screw the nut 52. As a result, the raising member 31 and the vertical frame 22A (22B) are connected. At this time, the vertical frame screw 51 located above comes into contact with the upper end of the vertical frame screw through hole 32a. The vertical frame screw 51 located below is located in the middle of the vertical frame screw through hole 32a.
　また、上枠２３の２つの嵩上げ部材用貫通孔２３４及び嵩上げ部材３１の２つの上枠用ねじ貫通孔３４ａに、２つの上枠用ねじ（ボルト）５３を貫通させてナット５４を螺合させる。これにより、嵩上げ部材３１と上枠２３が接続される。そして、上枠２３は、たて枠２２Ａ，２２Ｂに対する接続位置に位置決めされる。 Further, the nut 54 is screwed by passing the two upper frame screws (bolts) 53 through the two upper frame screw through holes 234 of the upper frame 23 and the two upper frame screw through holes 34a of the raising member 31. .. As a result, the raising member 31 and the upper frame 23 are connected. Then, the upper frame 23 is positioned at the connection position with respect to the vertical frames 22A and 22B.
　上枠２３とたて枠２２Ａ（２２Ｂ）を、嵩上げ部材３１を用いて接続すると、天井板１２７の側面に設けられた振れ止め部材４１が、防振ゴム４２を介して嵩上げ部材３１のたて枠接続部３２に接触する。これにより、かご室１２１の振れを抑制することができる。たて枠接続部３２の上下方向の長さは、少なくとも振れ止め部材４１（防振ゴム４２）に対向する長さに設定されている。 When the upper frame 23 and the vertical frame 22A (22B) are connected by using the raising member 31, the steady rest member 41 provided on the side surface of the ceiling plate 127 raises the raising member 31 via the anti-vibration rubber 42. It contacts the frame connection portion 32. As a result, the runout of the car chamber 121 can be suppressed. The vertical length of the vertical frame connecting portion 32 is set to at least a length facing the steady rest member 41 (vibration-proof rubber 42).
　次に、図７に示すように、上枠２３にスライダ２５を固定し、スライダ２５をガイドレール１７０に摺動可能に係合させる。このとき、スライダ２５を固定するためのねじは、接続部材用ねじ（ボルト）５５を用いる。すなわち、スライダ２５、接続部材３７の貫通孔及び上枠２３の２つの接続部材用貫通孔２３１ａに、２つの接続部材用ねじ（ボルト）５５を貫通させてナット５６を螺合させる。 Next, as shown in FIG. 7, the slider 25 is fixed to the upper frame 23, and the slider 25 is slidably engaged with the guide rail 170. At this time, a connecting member screw (bolt) 55 is used as the screw for fixing the slider 25. That is, the nut 56 is screwed by passing the two connecting member screws (bolts) 55 through the two connecting member through holes 231a of the slider 25, the through hole of the connecting member 37, and the upper frame 23.
　上枠２３にスライダ２５を固定後、かご室１２１の天井板１２７をかご枠１２２内に配置して吊り下げる。次に、かご枠１２２内に下枠２１及び側板１２６Ｃ，１２６Ｄを配置し、４つの側板１２６Ａ～１２６Ｄとかご床１２５を接続する。このとき、かご床１２５は、かご枠１２２の下枠２１に支持される。 After fixing the slider 25 to the upper frame 23, the ceiling plate 127 of the car chamber 121 is arranged in the car frame 122 and suspended. Next, the lower frame 21 and the side plates 126C and 126D are arranged in the car frame 122, and the four side plates 126A to 126D and the car floor 125 are connected to each other. At this time, the car floor 125 is supported by the lower frame 21 of the car frame 122.
　４つの側板１２６Ａ～１２６Ｄを接続する（組み立てる）際に、側板１２６Ａ～１２６Ｄと天井板１２７が干渉して天井板１２７の意匠を傷つける恐れがある。そのため、吊り下げている天井板１２７を側板１２６Ａ～１２６Ｄと干渉しない位置まで上昇させる。その際、かご枠１２２の上枠２３が天井板１２７に干渉するため、上枠２３の嵩上げ作業を行う。 When connecting (assembling) the four side plates 126A to 126D, the side plates 126A to 126D and the ceiling plate 127 may interfere with each other and damage the design of the ceiling plate 127. Therefore, the suspended ceiling plate 127 is raised to a position where it does not interfere with the side plates 126A to 126D. At that time, since the upper frame 23 of the car frame 122 interferes with the ceiling plate 127, the upper frame 23 is raised.
　嵩上げ作業では、天井板１２７を上昇させた場合に、その天井板１２７と干渉しない嵩上げ位置まで上枠２３を上昇させる。嵩上げ作業では、まず、２つのたて枠用ねじ（ボルト）５１とナット５２の締結を緩める。これにより、嵩上げ部材３１、及び嵩上げ部材３１に接続された上枠２３は、上方に移動可能になる。 In the raising work, when the ceiling plate 127 is raised, the upper frame 23 is raised to a raising position that does not interfere with the ceiling plate 127. In the raising work, first, the fastening of the two vertical frame screws (bolts) 51 and the nut 52 is loosened. As a result, the raising member 31 and the upper frame 23 connected to the raising member 31 can be moved upward.
　その後、図８に示すように、下方に位置するたて枠用ねじ５１がたて枠用ねじ貫通孔３２ａの下端に接触するまで、嵩上げ部材３１及び上枠２３を上昇させる。これにより、上枠２３は、嵩上げ位置に配置される。次に、２つのたて枠用ねじ（ボルト）５１とナット５２により、嵩上げ部材３１のたて枠接続部３２とたて枠２２Ａ（２２Ｂ）を締結する。これにより、上枠２３の嵩上げ作業が終了する。 After that, as shown in FIG. 8, the raising member 31 and the upper frame 23 are raised until the lower vertical frame screw 51 comes into contact with the lower end of the vertical frame screw through hole 32a. As a result, the upper frame 23 is arranged at the raised position. Next, the vertical frame 22A (22B) is fastened to the vertical frame connecting portion 32 of the raising member 31 by the two vertical frame screws (bolts) 51 and the nut 52. As a result, the raising work of the upper frame 23 is completed.
　かご枠１２２内において、４つの側板１２６Ａ～１２６Ｄを組み立てた後、４つの側板１２６Ａ～１２６Ｄと天井板１２７を接続する。このとき、天井板１２７を下降させる。次に、２つのたて枠用ねじ（ボルト）５１とナット５２の締結を緩める。そして、上方に位置するたて枠用ねじ５１がたて枠用ねじ貫通孔３２ａの上端に接触するまで、嵩上げ部材３１及び上枠２３を下降させる。これにより、上枠２３は、接続位置に配置される。 After assembling the four side plates 126A to 126D in the car frame 122, the four side plates 126A to 126D are connected to the ceiling plate 127. At this time, the ceiling plate 127 is lowered. Next, loosen the fastening of the two vertical frame screws (bolts) 51 and the nut 52. Then, the raising member 31 and the upper frame 23 are lowered until the vertical frame screw 51 located above comes into contact with the upper end of the vertical frame screw through hole 32a. As a result, the upper frame 23 is arranged at the connection position.
　次に、２つのたて枠用ねじ（ボルト）５１とナット５２により、嵩上げ部材３１のたて枠接続部３２とたて枠２２Ａ（２２Ｂ）を締結する。これにより、上枠２３は、接続位置において固定される。 Next, the vertical frame 22A (22B) is fastened to the vertical frame connecting portion 32 of the raising member 31 with two vertical frame screws (bolts) 51 and nuts 52. As a result, the upper frame 23 is fixed at the connection position.
　次に、図９に示すように、接続部材３７を用いて上枠２３とたて枠２２Ａを接続する。この接続部材３７は、上枠２３とたて枠２２Ａの接続強度を高める。嵩上げ部材３１による接続強度で十分である場合は、接続部材３７を省いてもよい。接続部材３７は、側面形状が略Ｌ字状に形成されている。 Next, as shown in FIG. 9, the upper frame 23 and the vertical frame 22A are connected using the connecting member 37. The connecting member 37 enhances the connection strength between the upper frame 23 and the vertical frame 22A. If the connection strength of the raising member 31 is sufficient, the connection member 37 may be omitted. The side surface of the connecting member 37 is formed in a substantially L shape.
　上述したように、接続部材３７は、既に上枠２３に固定されている。したがって、たて枠２２Ａ（２２Ｂ）に接続部材３７を固定する。すなわち、接続部材３７及びたて枠２２Ａ（２２Ｂ）の２つの接続部材用貫通孔２２１ａに、２つの接続部材用ねじ（ボルト）５５を貫通させてナット（不図示）を螺合させる。これにより、接続部材３７がたて枠２２Ａ（２２Ｂ）に固定される。 As described above, the connecting member 37 is already fixed to the upper frame 23. Therefore, the connecting member 37 is fixed to the vertical frame 22A (22B). That is, two connecting member screws (bolts) 55 are passed through the two connecting member through holes 221a of the connecting member 37 and the vertical frame 22A (22B), and a nut (not shown) is screwed. As a result, the connecting member 37 is fixed to the vertical frame 22A (22B).
　このように、本実施形態に係る乗りかご１２０は、たて枠２２Ａ，２２Ｂと上枠２３にたて枠用ねじ５１及び上枠用ねじ５３を用いて接続される嵩上げ部材３１を備える。嵩上げ部材３１は、たて枠用ねじ５１が貫通するたて枠用ねじ貫通孔３２ａと、上枠用ねじ５３が貫通する上枠用ねじ貫通孔３４ａを有する。そして、たて枠用ねじ貫通孔３２ａは、上下方向に延びる縦長に形成されている。これにより、たて枠用ねじ５１の締結を緩めることで、上枠２３に接続した状態の嵩上げ部材３１を簡単に上方へ移動させることができる。その結果、上枠２３の嵩上げ作業を容易にすることができる。さらに、嵩上げ部材３１は、上枠２３を嵩上げ位置に保持することができる。これにより、 As described above, the car 120 according to the present embodiment includes a raising member 31 connected to the vertical frames 22A and 22B and the upper frame 23 by using the vertical frame screws 51 and the upper frame screws 53. The raising member 31 has a vertical frame screw through hole 32a through which the vertical frame screw 51 penetrates, and an upper frame screw through hole 34a through which the upper frame screw 53 penetrates. The vertical frame screw through hole 32a is formed in a vertically long shape extending in the vertical direction. As a result, by loosening the fastening of the vertical frame screw 51, the raising member 31 connected to the upper frame 23 can be easily moved upward. As a result, the work of raising the upper frame 23 can be facilitated. Further, the raising member 31 can hold the upper frame 23 in the raising position. This will result in
　また、嵩上げ部材３１は、たて枠２２Ａ（２２Ｂ）にたて枠用ねじ５１を用いて接続されるたて枠接続部３２と、上枠２３に上枠用ねじ５３を用いて接続される上枠接続部３３とを有する。そして、上枠接続部３３は、上枠用ねじ貫通孔３４ａが形成されたねじ貫通片３４と、ねじ貫通片３４に連続し、上枠２３の下部を支える支持片３５を有する。これにより、上枠用ねじ５３に上枠２３の荷重が集中しないようにすることができる。 Further, the raising member 31 is connected to the vertical frame connecting portion 32 connected to the vertical frame 22A (22B) by using the vertical frame screw 51, and to the upper frame 23 by using the upper frame screw 53. It has an upper frame connecting portion 33. The upper frame connecting portion 33 has a screw through piece 34 in which the upper frame screw through hole 34a is formed, and a support piece 35 that is continuous with the screw through piece 34 and supports the lower part of the upper frame 23. As a result, the load of the upper frame 23 can be prevented from being concentrated on the upper frame screw 53.
　また、上枠接続部３３のねじ貫通片３４は、かご室１２１の前後方向において上枠２３に当接する。なお、かご室１２１の前後方向は、たて枠２２Ａ，２２Ｂが延びる上下方向と上枠２３が延びる左右方向に直交する方向である。したがって、嵩上げ部材３１を用いて上枠２３とたて枠２２Ａ，２２Ｂを接続することにより、たて枠２２Ａ，２２Ｂに対する上枠２３の前後方向の位置決めを行うことができる。 Further, the screw penetrating piece 34 of the upper frame connecting portion 33 abuts on the upper frame 23 in the front-rear direction of the car chamber 121. The front-rear direction of the car chamber 121 is a direction orthogonal to the vertical direction in which the vertical frames 22A and 22B extend and the left-right direction in which the upper frame 23 extends. Therefore, by connecting the upper frame 23 and the vertical frames 22A and 22B using the raising member 31, the upper frame 23 can be positioned in the front-rear direction with respect to the vertical frames 22A and 22B.
　また、嵩上げ部材３１において、たて枠用ねじ貫通孔３２ａと上枠用ねじ貫通孔３４ａは、貫通方向が同じである。これにより、作業者が姿勢を変えずに、たて枠用ねじ５１とナット５２を螺合させる作業と、上枠用ねじ５３とナット５４を螺合させる作業を行うことができる。その結果、嵩上げ部材３１のたて枠２２Ａ，２２Ｂ及び上枠２３に接続する際の作業性が向上する。 Further, in the raising member 31, the vertical frame screw through hole 32a and the upper frame screw through hole 34a have the same penetration direction. As a result, the operator can perform the work of screwing the vertical frame screw 51 and the nut 52 and the work of screwing the upper frame screw 53 and the nut 54 without changing the posture. As a result, workability when connecting the raising member 31 to the vertical frames 22A and 22B and the upper frame 23 is improved.
　また、嵩上げ部材３１とかご室１２１の振れ止め部材４１との間には、防振ゴム４２（防振材）が介在されている。これにより、かご室１２１の振れを抑制することができる。また、嵩上げ部材３１は、エレベーター１の据え付け後も、たて枠２２Ａ，２２Ｂ及び上枠２３に接続されている。そのため、エレベーター１の据え付け後に不要となる部品を削減することができる。 Further, a vibration-proof rubber 42 (vibration-proof material) is interposed between the raising member 31 and the steady rest member 41 of the cage chamber 121. As a result, the runout of the car chamber 121 can be suppressed. Further, the raising member 31 is connected to the vertical frames 22A and 22B and the upper frame 23 even after the elevator 1 is installed. Therefore, it is possible to reduce unnecessary parts after the installation of the elevator 1.
　さらに、嵩上げ部材３１は吊り下げ用孔３４ｂを有している。これにより、嵩上げ部材３１を任意の高さまで容易に運ぶことができる。また、上枠２３及びたて枠２２Ａ，２２Ｂに接続した場合は、かご枠１２２全体を吊り下げることができる。その結果、かご枠１２２の位置調整を容易に行うことができる。 Further, the raising member 31 has a hanging hole 34b. As a result, the raising member 31 can be easily carried to an arbitrary height. Further, when connected to the upper frame 23 and the vertical frames 22A and 22B, the entire car frame 122 can be suspended. As a result, the position of the car frame 122 can be easily adjusted.
