　ドア支持装置９は、かご枠３に支持されている。また、ドア支持装置９は、かご枠３にそれぞれ固定された一対の取付部材１６と、一対の取付部材１６及びかご枠３に接続された保持部材である一対の縦筋交い１７と、かご室２に対する一対の取付部材１６のそれぞれの変位をかご１の幅方向において個別に制限する一対の振れ止め装置１８とを有している。 The door support device 9 is supported by the car frame 3. The door support device 9 includes a pair of mounting members 16 fixed to the car frame 3, a pair of vertical members 17 that are holding members connected to the pair of mounting members 16 and the car frame 3, and the car room 2. And a pair of steady rests 18 for individually limiting the displacement of the pair of attachment members 16 in the width direction of the car 1.
　一対の取付部材１６は、一対の縦柱７に個別に固定されている。また、一対の取付部材１６のそれぞれは、かご１の奥行き方向に沿って水平に配置されている。さらに、一対の取付部材１６は、かご１の幅方向へ互いに離して配置されている。この例では、一対の取付部材１６のそれぞれが、かご１の幅方向におけるかご出入口４の範囲よりも外側に配置されている。 The pair of mounting members 16 are individually fixed to the pair of vertical columns 7. Further, each of the pair of attachment members 16 is disposed horizontally along the depth direction of the car 1. Further, the pair of attachment members 16 are arranged apart from each other in the width direction of the car 1. In this example, each of the pair of attachment members 16 is disposed outside the range of the car doorway 4 in the width direction of the car 1.
　また、一対の取付部材１６のそれぞれは、かご出入口４の上端部よりも高い位置に配置されている。この例では、図４に示すように、一対の取付部材１６のそれぞれがかご室２の天井上面２ｂよりも高い位置でかつ上枠６よりも低い位置に配置されている。また、この例では、図２に示すように、各取付部材１６の断面形状がＬ字状になっている。 Further, each of the pair of mounting members 16 is disposed at a position higher than the upper end portion of the car doorway 4. In this example, as shown in FIG. 4, each of the pair of attachment members 16 is disposed at a position higher than the ceiling upper surface 2 b of the cab 2 and lower than the upper frame 6. Moreover, in this example, as shown in FIG. 2, the cross-sectional shape of each attachment member 16 is L-shaped.
　一対の取付部材１６のそれぞれは、出入口側端部１６ａを有している。一対の取付部材１６のそれぞれの出入口側端部１６ａは、縦柱７よりもかご出入口４に近い位置に配置されている。これにより、一対の取付部材１６のそれぞれの出入口側端部１６ａは、かご１の幅方向においてかご出入口４の上方の空間を挟んで配置されている。一対の取付部材１６のそれぞれの出入口側端部１６ａには、ドアフレーム１０の裏面が介在部材１９を介して取り付けられている。これにより、かごドア装置８は、一対の取付部材１６に支持されている。各介在部材１９は、板を曲げて形成された部材である。 Each of the pair of attachment members 16 has an entrance / exit side end 16a. Each of the pair of attachment members 16 is disposed at a position closer to the car doorway 4 than the vertical column 7. Thereby, the respective entrance / exit side ends 16 a of the pair of attachment members 16 are arranged with the space above the car entrance 4 in the width direction of the car 1. The rear surface of the door frame 10 is attached to the respective entrance / exit end portions 16 a of the pair of attachment members 16 via intervening members 19. Thereby, the car door device 8 is supported by the pair of attachment members 16. Each interposed member 19 is a member formed by bending a plate.
　各縦筋交い１７は、第１接続部１７ａと、第２接続部１７ｂと、第１接続部１７ａ及び第２接続部１７ｂ間を繋ぐ棒状部１７ｃとを有している。この例では、棒状部１７ｃに取り付けられた接続金具が第１接続部１７ａ及び第２接続部１７ｂとしてそれぞれ用いられている。また、この例では、棒状部１７ｃに対する第１接続部１７ａ及び第２接続部１７ｂのそれぞれの位置が棒状部１７ｃの長手方向へ調整可能になっている。これにより、各縦筋交い１７における第１接続部１７ａと第２接続部１７ｂとの間の長さが調整可能になっている。 Each vertical bar crossing 17 has a first connecting portion 17a, a second connecting portion 17b, and a rod-like portion 17c that connects the first connecting portion 17a and the second connecting portion 17b. In this example, connection fittings attached to the rod-like portion 17c are used as the first connection portion 17a and the second connection portion 17b, respectively. Moreover, in this example, each position of the 1st connection part 17a and the 2nd connection part 17b with respect to the rod-shaped part 17c can be adjusted to the longitudinal direction of the rod-shaped part 17c. Thereby, the length between the 1st connection part 17a and the 2nd connection part 17b in each longitudinal cross 17 can be adjusted.
　各縦筋交い１７の第１接続部１７ａは、各取付部材１６の中間部に個別に接続されている。各縦筋交い１７の第２接続部１７ｂは、上枠６の両端部に個別に接続されている。これにより、各縦筋交い１７は、上枠６から下方に向かって縦柱７から離れる方向へ傾斜している。この例では、取付部材１６に固定されたフック部材に第１接続部１７ａが掛けられることにより、第１接続部１７ａが取付部材１６に接続されている。また、この例では、上枠６に固定されたフック部材に第２接続部１７ｂが掛けられることにより、第２接続部１７ｂが上枠６に接続されている。一対の取付部材１６のそれぞれは、各縦筋交い１７により水平に保持されている。 The first connecting portion 17a of each longitudinal bar crossing 17 is individually connected to the intermediate portion of each mounting member 16. The second connecting portions 17 b of the vertical bars 17 are individually connected to both end portions of the upper frame 6. Accordingly, each of the vertical bars 17 is inclined downward from the upper frame 6 in a direction away from the vertical column 7. In this example, the first connection portion 17 a is connected to the attachment member 16 by the first connection portion 17 a being hung on the hook member fixed to the attachment member 16. In this example, the second connecting portion 17 b is connected to the upper frame 6 by the second connecting portion 17 b being hooked on the hook member fixed to the upper frame 6. Each of the pair of attachment members 16 is held horizontally by each longitudinal bar 17.
　一対の振れ止め装置１８は、一対の取付部材１６のそれぞれとかご室２との間にそれぞれ設けられている。また、各振れ止め装置１８は、図３及び図４に示すように、縦筋交い１７の第１接続部１７ａよりも取付部材１６の出入口側端部１６ａに近い位置に配置されている。さらに、各振れ止め装置１８は、図２及び図３に示すように、かご１の幅方向におけるかご出入口４の範囲よりも外側に配置されている。かご１の幅方向内側に向かう方向への各取付部材１６の変位は、各振れ止め装置１８によって個別に阻止される。これにより、かご室２に対する各取付部材１６の変位が、かご１の幅方向において制限されている。なお、この例では、取付部材１６が第１の振れ止め対象部材とされ、かご室２が第２の振れ止め対象部材とされている。 The pair of steady rests 18 are provided between each of the pair of attachment members 16 and the car room 2. Further, as shown in FIGS. 3 and 4, each of the steady rest devices 18 is disposed at a position closer to the entrance / exit side end portion 16 a of the attachment member 16 than the first connection portion 17 a of the longitudinal bars 17. Further, as shown in FIGS. 2 and 3, each of the steady rests 18 is disposed outside the range of the car doorway 4 in the width direction of the car 1. The displacement of each mounting member 16 in the direction toward the inner side in the width direction of the car 1 is individually prevented by each steadying device 18. Thereby, the displacement of each attachment member 16 with respect to the car room 2 is limited in the width direction of the car 1. In this example, the attachment member 16 is the first steadying target member, and the car room 2 is the second steadying target member.
　図５は、図２の振れ止め装置１８を示す拡大図である。各振れ止め装置１８は、第１の振れ止め対象部材としての取付部材１６に設けられた規制部材２１と、第２の振れ止め対象部材としてのかご室２に設けられたストッパ部材２２とを有している。 FIG. 5 is an enlarged view showing the steady rest device 18 of FIG. Each of the steady rests 18 has a regulating member 21 provided on the mounting member 16 as a first steady stop target member and a stopper member 22 provided in the car chamber 2 as a second steady stop target member. are doing.
　規制部材２１は、取付部材１６に固定されたＬ字状の支持部２３と、支持部２３に設けられた振れ止め部２４とを有している。 The regulating member 21 has an L-shaped support part 23 fixed to the mounting member 16 and a steadying part 24 provided on the support part 23.
　振れ止め部２４は、ジャッキボルト２４ａと、ジャッキボルト２４ａの端部に固定されているゴム製の緩衝部２４ｂとを有している。振れ止め部２４は、支持部２３に形成されたねじ穴にジャッキボルト２４ａが嵌められた状態で支持部２３に取り付けられている。また、ジャッキボルト２４ａは、かご１の幅方向に沿って配置されている。各振れ止め装置１８では、緩衝部２４ｂをかご１の幅方向内側に向けて振れ止め部２４が配置されている。取付部材１６及び支持部２３に対する振れ止め部２４の位置は、ジャッキボルト２４ａの回転により、かご１の幅方向へ調整可能になっている。 The steady rest 24 has a jack bolt 24a and a rubber buffer 24b fixed to the end of the jack bolt 24a. The steady rest part 24 is attached to the support part 23 in a state in which the jack bolt 24 a is fitted in the screw hole formed in the support part 23. Further, the jack bolts 24 a are arranged along the width direction of the car 1. In each of the steady rests 18, the steady rest 24 is disposed with the buffer portion 24b facing inward in the width direction of the car 1. The position of the steady rest 24 with respect to the mounting member 16 and the support 23 can be adjusted in the width direction of the car 1 by the rotation of the jack bolt 24a.
　ストッパ部材２２は、かご室２の天井上面２ｂに固定された断面Ｌ字状の部材である。また、ストッパ部材２２は、規制部材２１よりもかご１の幅方向内側に配置されている。かご室２の天井上面２ｂから上方へ突出するストッパ部材２２の突出部には、緩衝部２４ｂが当たる当り面が形成されている。これにより、規制部材２１は、かご１の幅方向においてストッパ部材２２を介してかご室２を受けている。かご室２に対する各取付部材１６の変位は、規制部材２１がストッパ部材２２を介してかご室２を受けることにより、かご１の幅方向において制限される。 The stopper member 22 is a member having an L-shaped cross section fixed to the ceiling upper surface 2 b of the cab 2. The stopper member 22 is disposed on the inner side in the width direction of the car 1 than the regulating member 21. An abutting surface against which the buffer portion 24b hits is formed on the protruding portion of the stopper member 22 protruding upward from the ceiling upper surface 2b of the cab 2. Thereby, the regulating member 21 receives the car chamber 2 via the stopper member 22 in the width direction of the car 1. The displacement of each mounting member 16 with respect to the car room 2 is limited in the width direction of the car 1 when the regulating member 21 receives the car room 2 via the stopper member 22.
　このようなエレベータのドア支持装置９では、一対の取付部材１６のそれぞれとかご室２との間に一対の振れ止め装置１８がそれぞれ設けられている。このため、各振れ止め装置１８を介して各取付部材１６の変位をかご室２で受けることができる。これにより、例えば、かごドア１２の移動の反転時の加減速によって各取付部材１６に荷重が加わる場合、かご室２に対して各取付部材１６をかご１の幅方向へ変位しにくくすることができる。従って、各取付部材１６の強度を小さくすることができ、各取付部材１６の小型化及び軽量化を図ることができる。また、一対の取付部材１６のそれぞれとかご室２との間に各振れ止め装置１８が配置されることから、各振れ止め装置１８の小型化及び軽量化も図ることができる。このようなことから、ドア支持装置９を小型化及び軽量化することができ、かご１の全体の軽量化を図ることができる。さらに、かご１の幅方向における各取付部材１６の寸法を大きくする必要がなくなることから、かご１の全体の幅方向寸法の増大を防止することもでき、昇降路の水平断面積の増大を抑制することができる。 In such an elevator door support device 9, a pair of steadying devices 18 are provided between each of the pair of mounting members 16 and the car room 2. For this reason, the displacement of each attachment member 16 can be received in the cab 2 via each steadying device 18. Thereby, for example, when a load is applied to each attachment member 16 by acceleration / deceleration at the time of reversal of the movement of the car door 12, it is difficult to displace each attachment member 16 in the width direction of the car 1 with respect to the car room 2. it can. Therefore, the strength of each mounting member 16 can be reduced, and each mounting member 16 can be reduced in size and weight. Moreover, since each steadying apparatus 18 is arrange | positioned between each of a pair of attachment member 16 and the cab 2, each steadying apparatus 18 can also be reduced in size and weight. For this reason, the door support device 9 can be reduced in size and weight, and the overall weight of the car 1 can be reduced. Furthermore, since it is not necessary to increase the size of each mounting member 16 in the width direction of the car 1, it is possible to prevent an increase in the overall width direction dimension of the car 1 and to suppress an increase in the horizontal cross-sectional area of the hoistway. can do.
　また、かごドア装置８を支持する各取付部材１６は、かご枠３に設けられている。このため、かごドア装置８のドアフレーム１０をかご室２に直接固定する場合に比べて、かごドア装置８の動作による振動をかご室２内に伝わりにくくすることができ、かご室２内の騒音及び振動を低減することができる。また、かご室２が防振ゴムを介してかご枠３に支持されている場合、かごドア装置８のドアフレーム１０をかご室２に直接固定すると、例えばかご室２に対する乗客の乗降時にかご室２がかご枠３に対して揺れて、かごドア装置８の位置がかご枠３に対してずれやすくなる。しかし、本実施の形態では、かご枠３に対するかごドア装置８の位置ずれを防止することができる。これにより、例えば、かご１の移動時にかごドア装置８が乗場ドア装置の係合部に接触することを防止することができる。また、かごドア装置８のかごドア１２がドアレール１１から外れにくくすることもできる。 Further, each mounting member 16 that supports the car door device 8 is provided in the car frame 3. For this reason, compared with the case where the door frame 10 of the car door device 8 is directly fixed to the car room 2, the vibration caused by the operation of the car door device 8 can be made difficult to be transmitted to the car room 2. Noise and vibration can be reduced. Further, when the car room 2 is supported by the car frame 3 via the vibration isolating rubber, if the door frame 10 of the car door device 8 is directly fixed to the car room 2, the car room is, for example, when passengers get in and out of the car room 2. 2 swings with respect to the car frame 3, and the position of the car door device 8 easily shifts with respect to the car frame 3. However, in the present embodiment, the positional deviation of the car door device 8 with respect to the car frame 3 can be prevented. Thereby, for example, the car door device 8 can be prevented from coming into contact with the engaging portion of the landing door device when the car 1 is moved. Further, the car door 12 of the car door device 8 can be made difficult to come off from the door rail 11.
　さらに、各取付部材１６及び各振れ止め装置１８のそれぞれは、かご１の幅方向におけるかご出入口４の範囲よりも外側に配置されている。このため、かご室２の天井上面２ｂに設置されている機器に対して各取付部材１６及び各振れ止め装置１８が干渉することを回避することができる。これにより、かご室２の天井上面２ｂにおける機器のレイアウト設計を容易にすることができる。また、かご室２の天井上面２ｂに設置された機器よりも高い位置に各取付部材１６及び各振れ止め装置１８を配置する必要がなくなることから、かご１の全体の高さ寸法の縮小化を図ることができる。 Furthermore, each of the attachment members 16 and each of the steady rests 18 is disposed outside the range of the car doorway 4 in the width direction of the car 1. For this reason, it can avoid that each attachment member 16 and each steadying apparatus 18 interfere with the apparatus installed in the ceiling upper surface 2b of the cab 2. Thereby, the layout design of the apparatus in the ceiling upper surface 2b of the cab 2 can be facilitated. Moreover, since it is not necessary to arrange each attachment member 16 and each steady rest device 18 at a position higher than the equipment installed on the ceiling upper surface 2b of the car room 2, the overall height of the car 1 can be reduced. Can be planned.
　また、一対の振れ止め装置１８のそれぞれは、取付部材１６に設けられた規制部材２１と、かご室２に設けられたストッパ部材２２とを有している。このため、例えば、規制部材２１がかご室２の側面２ｅとかご１の幅方向に対向していない場合でも、かご室２に固定したストッパ部材２２を規制部材２１にかご１の幅方向において対向させることによって、かご１の幅方向における取付部材１６の変位をかご室２で受けるようにすることができる。 Each of the pair of steady rests 18 includes a regulating member 21 provided on the mounting member 16 and a stopper member 22 provided on the car room 2. For this reason, for example, even when the regulating member 21 does not face the side surface 2e of the cab 2 and the width direction of the car 1, the stopper member 22 fixed to the cab 2 faces the regulating member 21 in the width direction of the car 1. By doing so, the displacement of the attachment member 16 in the width direction of the car 1 can be received by the car room 2.
　また、規制部材２１では、支持部２３に対するジャッキボルト２４ａの位置がかご１の幅方向へ調整可能になっている。このため、かご室２に対する各取付部材１６の位置をかご１の幅方向へ調整することができ、かご出入口４に対するかごドア装置８の位置をかご１の幅方向へ容易に調整することができる。 In the restricting member 21, the position of the jack bolt 24 a relative to the support portion 23 can be adjusted in the width direction of the car 1. For this reason, the position of each attachment member 16 with respect to the car room 2 can be adjusted in the width direction of the car 1, and the position of the car door device 8 with respect to the car doorway 4 can be easily adjusted in the width direction of the car 1. .
　なお、上記の例では、縦柱７に固定された取付部材１６が縦筋交い１７によって水平に保持されている。しかし、取付部材１６が縦柱７に水平に保持可能であれば、縦筋交い１７はなくてもよい。 In the above example, the mounting member 16 fixed to the vertical column 7 is held horizontally by the vertical bars 17. However, as long as the attachment member 16 can be held horizontally by the vertical column 7, there is no need for the vertical bars 17.
　また、上記の例では、取付部材１６の断面形状がＬ字状になっている。しかし、取付部材１６の断面形状は、これに限定されず、どのような形状であってもよい。例えば、取付部材１６を平板とし、平板の厚さ方向をかご１の幅方向と一致させて取付部材１６を配置してもよい。 In the above example, the cross-sectional shape of the mounting member 16 is L-shaped. However, the cross-sectional shape of the attachment member 16 is not limited to this, and may be any shape. For example, the mounting member 16 may be a flat plate, and the mounting member 16 may be arranged such that the thickness direction of the flat plate coincides with the width direction of the car 1.
　また、上記の例では、規制部材２１が設けられた第１の振れ止め対象部材が取付部材１６とされ、ストッパ部材２２が設けられた第２の振れ止め対象部材がかご室２とされている。しかし、規制部材２１が設けられた第１の振れ止め対象部材をかご室２とし、ストッパ部材２２が設けられた第２の振れ止め対象部材を取付部材１６としてもよい。 In the above example, the first steadying target member provided with the regulating member 21 is the mounting member 16, and the second steadying target member provided with the stopper member 22 is the cab 2. . However, the first steadying target member provided with the regulating member 21 may be the car chamber 2, and the second steadying target member provided with the stopper member 22 may be the mounting member 16.
　また、上記の例では、各振れ止め装置１８においてストッパ部材２２が規制部材２１よりもかご１の幅方向内側に配置されている。しかし、各振れ止め装置１８において規制部材２１よりもかご１の幅方向外側にストッパ部材２２を配置してもよい。 Further, in the above example, the stopper member 22 is arranged on the inner side in the width direction of the car 1 than the regulating member 21 in each steadying device 18. However, the stopper member 22 may be arranged on the outer side in the width direction of the car 1 with respect to the restraining member 21 in each steadying device 18.
　また、上記の例では、緩衝部２４ｂがジャッキボルト２４ａに固定されている。しかし、ジャッキボルト２４ａに緩衝部２４ｂを固定せずに、ストッパ部材２２に緩衝部２４ｂを固定してもよい。 In the above example, the buffer portion 24b is fixed to the jack bolt 24a. However, the buffer portion 24b may be fixed to the stopper member 22 without fixing the buffer portion 24b to the jack bolt 24a.
　また、上記の例では、取付部材１６に固定された支持部２３にジャッキボルト２４ａが取り付けられている。しかし、取付部材１６に形成されたねじ穴にジャッキボルト２４ａを嵌めることにより、ジャッキボルト２４ａを取付部材１６に直接取り付けてもよい。このようにすれば、支持部２３をなくすことができ、振れ止め装置１８の部品点数の低減化を図ることができる。 In the above example, the jack bolt 24 a is attached to the support portion 23 fixed to the attachment member 16. However, the jack bolt 24 a may be directly attached to the attachment member 16 by fitting the jack bolt 24 a into the screw hole formed in the attachment member 16. In this way, the support part 23 can be eliminated, and the number of parts of the steady rest device 18 can be reduced.
　また、上記の例では、各取付部材１６がかご枠３のみに支持されている。しかし、各取付部材１６のそれぞれからかご１の下部に達する一対の補強柱を追加して、かご枠３及び一対の補強柱によって各取付部材１６を支持してもよい。このようにすれば、例えばかごドア装置８の動作によって各取付部材１６にねじり力が作用する場合でも、一対の補強柱によって各取付部材１６を変形しにくくすることができる。この場合、各補強柱の長手方向の引張強度及び圧縮強度によって各取付部材１６のねじり剛性を補強することができることから、一対の補強柱の太さを細くすることができ、かご１の全体としては軽量化を図ることができる。 In the above example, each mounting member 16 is supported only by the car frame 3. However, a pair of reinforcing columns reaching the lower part of the car 1 from each of the mounting members 16 may be added, and the mounting members 16 may be supported by the car frame 3 and the pair of reinforcing columns. If it does in this way, even when a torsional force acts on each attachment member 16 by operation | movement of the car door apparatus 8, for example, it can make it difficult to deform | transform each attachment member 16 with a pair of reinforcement pillar. In this case, since the torsional rigidity of each mounting member 16 can be reinforced by the tensile strength and the compressive strength in the longitudinal direction of each reinforcing column, the thickness of the pair of reinforcing columns can be reduced. Can be reduced in weight.
　実施の形態２．
　図６は、この発明の実施の形態２によるエレベータのドア支持装置が設けられているかごを示す模式的な斜視図である。本実施の形態では、かご出入口４の上端部からかご室２の天井上面２ｂまでの高さが実施の形態１よりも高くなっている。これにより、本実施の形態では、かごドア装置８のドアフレーム１０の下面及び上面がいずれも、かご室２の天井上面２ｂよりも低い位置に配置されている。 Embodiment 2. FIG.
FIG. 6 is a schematic perspective view showing a car provided with an elevator door support device according to Embodiment 2 of the present invention. In the present embodiment, the height from the upper end of the car doorway 4 to the ceiling upper surface 2b of the car room 2 is higher than that in the first embodiment. Thereby, in this Embodiment, the lower surface and upper surface of the door frame 10 of the car door apparatus 8 are both arrange | positioned in the position lower than the ceiling upper surface 2b of the cab 2.
　図７は、図６のかご１を示す正面図である。図８は、図６のかご１を示す上面図である。図９は、図６のかご１を示す側面図である。ドア支持装置９は、かご枠３にそれぞれ固定された一対の取付部材３１と、かご室２に対する一対の取付部材３１のそれぞれの変位をかご１の幅方向において個別に制限する一対の振れ止め装置３２とを有している。 FIG. 7 is a front view showing the car 1 of FIG. FIG. 8 is a top view showing the car 1 of FIG. FIG. 9 is a side view showing the car 1 of FIG. The door support device 9 includes a pair of mounting members 31 fixed to the car frame 3 and a pair of steadying devices for individually limiting displacement of the pair of mounting members 31 relative to the car room 2 in the width direction of the car 1. 32.
　一対の取付部材３１は、一対の縦柱７に個別に固定されている。また、一対の取付部材３１のそれぞれは、かご１の奥行き方向に沿って水平に配置されている。さらに、一対の取付部材３１は、かご１の幅方向へ互いに離して配置されている。この例では、一対の取付部材３１のそれぞれが、かご１の幅方向におけるかご室２の範囲よりも外側に配置されている。また、各取付部材３１の厚さ方向は、かご１の幅方向と一致している。これにより、かご１の高さ方向における各取付部材３１の寸法は、かご１の幅方向における各取付部材３１の寸法よりも大きくなっている。 The pair of mounting members 31 are individually fixed to the pair of vertical columns 7. Further, each of the pair of attachment members 31 is disposed horizontally along the depth direction of the car 1. Further, the pair of attachment members 31 are arranged apart from each other in the width direction of the car 1. In this example, each of the pair of attachment members 31 is disposed outside the range of the car room 2 in the width direction of the car 1. Further, the thickness direction of each mounting member 31 coincides with the width direction of the car 1. Thereby, the dimension of each attachment member 31 in the height direction of the car 1 is larger than the dimension of each attachment member 31 in the width direction of the car 1.
　また、一対の取付部材３１のそれぞれは、かご出入口４の上端部よりも高い位置でかつかご室２の天井上面２ｂよりも低い位置に配置されている。これにより、一方の取付部材３１は、かご室２の一方の側面２ｅと対向している。また、他方の取付部材３１は、かご室２の他方の側面２ｅと対向している。 Further, each of the pair of mounting members 31 is disposed at a position higher than the upper end portion of the car entrance 4 and lower than the ceiling upper surface 2b of the car room 2. Thereby, one attachment member 31 is opposed to one side surface 2e of the cab 2. The other attachment member 31 faces the other side surface 2e of the cab 2.
　一対の取付部材３１のそれぞれは、出入口側端部３１ａを有している。一対の取付部材３１のそれぞれの出入口側端部３１ａは、縦柱７よりもかご出入口４に近い位置に配置されている。これにより、一対の取付部材３１のそれぞれの出入口側端部３１ａは、かご１の幅方向においてかご出入口４の上方の空間を挟んで配置されている。一対の取付部材３１のそれぞれの出入口側端部３１ａには、ドアフレーム１０の裏面が介在部材１９を介して取り付けられている。これにより、かごドア装置８は、一対の取付部材３１に支持されている。この例では、実施の形態１の縦筋交い１７を用いずに各取付部材３１が各縦柱７に水平に固定されている。 Each of the pair of attachment members 31 has an entrance / exit side end 31a. The respective entrance / exit side end portions 31 a of the pair of attachment members 31 are arranged at positions closer to the car entrance 4 than the vertical column 7. Thereby, the respective entrance / exit side ends 31 a of the pair of attachment members 31 are arranged with the space above the car entrance 4 in the width direction of the car 1. The rear surface of the door frame 10 is attached to the respective entrance / exit end portions 31 a of the pair of attachment members 31 via the interposition members 19. Thereby, the car door device 8 is supported by the pair of attachment members 31. In this example, each attachment member 31 is horizontally fixed to each vertical column 7 without using the vertical cross 17 of the first embodiment.
　各振れ止め装置３２は、一対の取付部材３１のそれぞれとかご室２との間に配置されている。また、各振れ止め装置３２は、図７及び図８に示すように、かご１の幅方向におけるかご室２の範囲よりも外側に配置されている。かご１の幅方向内側に向かう方向への各取付部材３１の変位は、各振れ止め装置３２によって個別に阻止される。これにより、かご室２に対する各取付部材３１の変位が、かご１の幅方向において制限される。 Each of the steady rests 32 is disposed between each of the pair of mounting members 31 and the cab 2. Moreover, each steadying apparatus 32 is arrange | positioned outside the range of the cage | basket | chamber 2 in the width direction of the cage | basket | car 1, as shown in FIG.7 and FIG.8. The displacement of each mounting member 31 in the direction toward the inner side in the width direction of the car 1 is individually prevented by each steadying device 32. Thereby, the displacement of each attachment member 31 with respect to the car room 2 is limited in the width direction of the car 1.
　図１０は、図７の振れ止め装置３２を示す拡大図である。各振れ止め装置３２は、第１の振れ止め対象部材としての取付部材３１に設けられた規制部材３３を有している。この例では、規制部材３３が取付部材３１の出入口側端部３１ａに設けられている。 FIG. 10 is an enlarged view showing the steady rest device 32 of FIG. Each steadying device 32 has a regulating member 33 provided on a mounting member 31 as a first steadying target member. In this example, the regulating member 33 is provided at the entrance / exit side end 31 a of the mounting member 31.
　規制部材３３は、ジャッキボルト３３ａと、ジャッキボルト３３ａの端部に固定されているゴム製の緩衝部３３ｂとを有している。規制部材３３は、取付部材３１に設けられた貫通穴にジャッキボルト３３ａが通された状態で取付部材３１に取り付けられている。また、ジャッキボルト３３ａは、かご１の幅方向に沿って配置されている。 The regulating member 33 has a jack bolt 33a and a rubber buffer 33b fixed to the end of the jack bolt 33a. The restriction member 33 is attached to the attachment member 31 in a state where the jack bolt 33 a is passed through the through hole provided in the attachment member 31. Further, the jack bolts 33 a are arranged along the width direction of the car 1.
　取付部材３１に対する規制部材３３の位置は、かご１の幅方向へ調整可能になっている。この例では、ジャッキボルト３３ａに取り付けられた２つのナットの間で取付部材３１が締め付けられることにより、取付部材３１に対する規制部材３３の位置が固定されている。なお、取付部材３１に固定されたナットにジャッキボルト３３ａが嵌められ、ジャッキボルト３３ａの回転により、取付部材３１に対する規制部材３３の位置が調整されるようになっていてもよい。 The position of the restricting member 33 relative to the mounting member 31 can be adjusted in the width direction of the car 1. In this example, the position of the restriction member 33 relative to the attachment member 31 is fixed by tightening the attachment member 31 between two nuts attached to the jack bolt 33a. In addition, the jack bolt 33a may be fitted to the nut fixed to the mounting member 31, and the position of the regulating member 33 with respect to the mounting member 31 may be adjusted by the rotation of the jack bolt 33a.
　各振れ止め装置３２では、緩衝部３３ｂをかご１の幅方向内側に向けて規制部材３３が配置されている。従って、規制部材３３の緩衝部３３ｂは、かご室２の側面２ｅを直接受けている。かご室２に対する各取付部材３１の変位は、規制部材３３がかご室２の側面２ｅを受けることにより、かご１の幅方向において制限される。他の構成は、実施の形態１と同様である。 In each of the steady rests 32, the restricting member 33 is disposed with the buffer portion 33b facing inward in the width direction of the car 1. Therefore, the buffer portion 33 b of the restricting member 33 directly receives the side surface 2 e of the cab 2. The displacement of each attachment member 31 with respect to the car room 2 is limited in the width direction of the car 1 when the regulating member 33 receives the side surface 2e of the car room 2. Other configurations are the same as those in the first embodiment.
　このようなエレベータのドア支持装置９では、規制部材３３がかご室２の側面２ｅを直接受けることにより、かご室２に対する各取付部材３１の変位がかご１の幅方向において制限される。このため、実施の形態１と同様の効果を得ることができる。また、規制部材３３がかご室２の側面２ｅを直接受けることから、かご室２に対する取付部材３１の変位を制限するために、振れ止め装置３２の追加の部材をかご室２に設ける必要がなくなる。これにより、ドア支持装置９の部品点数を減らすことができ、コストの低減化を図ることができる。 In such an elevator door support device 9, the regulating member 33 directly receives the side surface 2 e of the car room 2, whereby the displacement of each mounting member 31 with respect to the car room 2 is limited in the width direction of the car 1. For this reason, the same effect as Embodiment 1 can be acquired. Further, since the regulating member 33 directly receives the side surface 2e of the car room 2, it is not necessary to provide an additional member of the steady rest device 32 in the car room 2 in order to limit the displacement of the mounting member 31 with respect to the car room 2. . Thereby, the number of parts of the door support device 9 can be reduced, and the cost can be reduced.
　また、かご１の高さ方向における各取付部材３１の寸法は、かご１の幅方向における各取付部材３１の寸法よりも大きくなっている。このため、かご１の高さ方向における各取付部材３１の強度を大きくすることができる。これにより、実施の形態１で用いられている縦筋交い１７がなくても、かごドア装置８の重量を各取付部材３１で支持することができる。従って、ドア支持装置９の部品点数を減らすことができ、コストの低減化を図ることができる。 In addition, the dimension of each mounting member 31 in the height direction of the car 1 is larger than the dimension of each mounting member 31 in the width direction of the car 1. For this reason, the strength of each attachment member 31 in the height direction of the car 1 can be increased. As a result, the weight of the car door device 8 can be supported by the mounting members 31 even without the longitudinal bars 17 used in the first embodiment. Therefore, the number of parts of the door support device 9 can be reduced, and the cost can be reduced.
　また、かご室２に対する各取付部材３１の変位をかご１の幅方向において制限するために、実施の形態１で用いられている縦筋交い１７の第１接続部１７ａを取付部材３１に接続し、第１接続部１７ａの位置よりもかご室２の幅方向内側の位置で縦筋交い１７の第２接続部１７ｂを上枠６に接続することも考えられる。しかし、実施の形態２のように、各取付部材３１がかご室２の天井上面２ｂの位置よりも低い位置に配置されている場合には、かご室２の上部の角部と縦筋交い１７とが干渉することにより、縦筋交い１７の第２接続部１７ｂをかご室２の幅方向内側に配置することが難しくなってしまう。これに対して、本実施の形態では、かご１の幅方向における各取付部材１６の変位が一対の振れ止め装置３２によって制限される。このため、各取付部材３１がかご室２の天井上面２ｂの位置よりも低い位置に配置されている場合であっても、かご１の幅方向における各取付部材１６の変位を縦筋交い１７によって制限する必要がなくなり、かご１の幅方向における各取付部材１６の変位を容易に制限することができる。 In addition, in order to limit the displacement of each attachment member 31 with respect to the car room 2 in the width direction of the car 1, the first connection portion 17 a of the longitudinal bar 17 used in the first embodiment is connected to the attachment member 31. It is also conceivable to connect the second connecting portion 17b of the longitudinal bars 17 to the upper frame 6 at a position on the inner side in the width direction of the cab 2 from the position of the first connecting portion 17a. However, when each attachment member 31 is disposed at a position lower than the position of the ceiling upper surface 2b of the cab 2 as in the second embodiment, the corners of the upper portion of the cab 2 and the longitudinal bars 17 Will interfere with the arrangement of the second connecting portion 17b of the vertical bar crossing 17 inside the cab 2 in the width direction. On the other hand, in the present embodiment, the displacement of each mounting member 16 in the width direction of the car 1 is limited by the pair of steadying devices 32. For this reason, even if each attachment member 31 is arranged at a position lower than the position of the ceiling upper surface 2 b of the car room 2, the displacement of each attachment member 16 in the width direction of the car 1 is restricted by the longitudinal bars 17. Therefore, the displacement of each mounting member 16 in the width direction of the car 1 can be easily limited.
　なお、上記の例では、規制部材３３が設けられた第１の振れ止め対象部材が取付部材３１とされている。しかし、規制部材３３が設けられた第１の振れ止め対象部材をかご室２としてもよい。この場合、規制部材３３は、緩衝部３３ｂをかご１の幅方向外側に向けてかご室２の側面２ｅに設けられる。また、この場合、規制部材３３の緩衝部３３ｂが取付部材３１を受けることにより、かご室２に対する各取付部材３１の変位がかご１の幅方向において制限される。 In the above example, the first steadying target member provided with the regulating member 33 is the mounting member 31. However, the first steadying target member provided with the regulating member 33 may be the cab 2. In this case, the regulating member 33 is provided on the side surface 2 e of the car room 2 with the buffer portion 33 b facing outward in the width direction of the car 1. In this case, the buffer portion 33 b of the regulating member 33 receives the mounting member 31, so that the displacement of each mounting member 31 with respect to the car room 2 is limited in the width direction of the car 1.
　また、上記の例では、緩衝部３３ｂがジャッキボルト３３ａに固定されている。しかし、ジャッキボルト３３ａに緩衝部３３ｂを固定せずに、かご室２の側面２ｅに緩衝部３３ｂを固定してもよい。 In the above example, the buffer portion 33b is fixed to the jack bolt 33a. However, the buffer portion 33b may be fixed to the side surface 2e of the cab 2 without fixing the buffer portion 33b to the jack bolt 33a.
　また、上記の例では、各取付部材３１がかご枠３のみに支持されている。しかし、各取付部材３１のそれぞれからかご１の下部に達する一対の補強柱を追加して、かご枠３及び一対の補強柱によって各取付部材３１を支持してもよい。このようにすれば、例えばかごドア装置８の動作によって各取付部材３１にねじり力が作用する場合でも、一対の補強柱によって各取付部材３１を変形しにくくすることができる。この場合、各補強柱の長手方向の引張強度及び圧縮強度によって各取付部材３１のねじり剛性を補強することができることから、一対の補強柱の太さを細くすることができ、かご１の全体としては軽量化を図ることができる。 Further, in the above example, each mounting member 31 is supported only by the car frame 3. However, a pair of reinforcing columns reaching the lower part of the car 1 from each of the mounting members 31 may be added, and the mounting members 31 may be supported by the car frame 3 and the pair of reinforcing columns. If it does in this way, even when a torsional force acts on each attachment member 31 by operation | movement of the car door apparatus 8, for example, it can make it difficult to deform | transform each attachment member 31 with a pair of reinforcement pillar. In this case, since the torsional rigidity of each mounting member 31 can be reinforced by the tensile strength and the compressive strength in the longitudinal direction of each reinforcing column, the thickness of the pair of reinforcing columns can be reduced. Can be reduced in weight.
