It comprises a pair of fixing members 24 that hold 8 in a car 1 direction so as to be rotatable, and a buffer mechanism 25 that is connected to the holding member 8 and expands and contracts in the car 1 direction.

回転体７は、図２に示すように昇降路３の壁面３ａに沿って垂下した制御ケーブル４に対向している。保持部材８は、中間部から先端部がかご１方向に曲げて形成された一対の板材からなり、中間部と先端部とに形成された孔８ａに回転体７の両端部に突出して設けられたローラー軸１３を挿入し、このローラー軸１３に固定具９を装着して回転体７を回転自在に保持している。 As shown in FIG. 2, the rotating body 7 faces the control cable 4 that hangs down along the wall surface 3 a of the hoistway 3. The holding member 8 is made of a pair of plate materials formed by bending the intermediate portion and the tip portion in the direction of the car 1, and is provided in a hole 8 a formed in the intermediate portion and the tip portion so as to protrude from both end portions of the rotating body 7. The roller shaft 13 is inserted, and the fixing member 9 is attached to the roller shaft 13 to hold the rotating body 7 rotatably.

かご１の底部１ａに保持部材８を回動可能に保持する一対の固定部材２４が配設されている。保持部材８は端部に孔８ａが形成されており、この孔８ａと一対の固定部材２４の一端部に設けられた孔２４ａとに取付けボルト１０の軸部を挿通して、保持部材８が回動可能に取付けボルト１０の軸部に固定具９を装着している。これらにより、回転体７を保持した保持部材８は、２点鎖線で回動した位置を示すように、かご１の底部１ａに配設した固定部材２４に回動可能に保持されている。 A pair of fixing members 24 that rotatably hold the holding member 8 are disposed on the bottom 1a of the car 1. The holding member 8 is formed with a hole 8a at its end, and the shaft of the mounting bolt 10 is inserted into the hole 8a and a hole 24a provided at one end of the pair of fixing members 24 so that the holding member 8 A fixing tool 9 is attached to the shaft portion of the mounting bolt 10 so as to be rotatable. Accordingly, the holding member 8 holding the rotating body 7 is rotatably held by the fixing member 24 disposed on the bottom 1a of the car 1 so as to indicate the position rotated by the two-dot chain line.

緩衝機構２５は、バネロッド２０と、バネ２１と、ストッパ２２と、金具２３とで構成されている。
バネロッド２０はバネ２１を装着する軸部の一端部にＬ字型の連結部２０ａが形成されており、さらに、連結部２０ａには保持部材８と連結するための孔２０ｂが形成されている。そして、孔２０ｂと保持部材８に形成された孔８ａとに取付けボルト１０の軸部を挿入し、バネロッド２０が回動可能に取付けボルト１０の軸部に固定具９を装着している。 The buffer mechanism 25 includes a spring rod 20, a spring 21, a stopper 22, and a metal fitting 23.
The spring rod 20 has an L-shaped connecting portion 20 a formed at one end of a shaft portion on which the spring 21 is mounted, and further, a hole 20 b for connecting to the holding member 8 is formed in the connecting portion 20 a. And the axial part of the attachment bolt 10 is inserted in the hole 20b and the hole 8a formed in the holding member 8, and the fixing tool 9 is attached to the axial part of the attachment bolt 10 so that the spring rod 20 can rotate.

一方、バネロッド２０の軸部は、バネ２１が装着された状態で、かご１の底部１ａに固定された金具２３に形成された孔２３ａに挿入され、挿入された軸部の端部にバネロッド２０が昇降路３の壁面３ａ側に飛び出すことを防ぐストッパ２２が固定されている。これらによる緩衝機構２５により、回転体７を保持した保持部材８がかご１方向へ回動した時にバネ２１が縮む。 On the other hand, the shaft portion of the spring rod 20 is inserted into the hole 23a formed in the metal fitting 23 fixed to the bottom portion 1a of the car 1 with the spring 21 mounted, and the spring rod 20 is inserted into the end portion of the inserted shaft portion. A stopper 22 is fixed to prevent the jumping out to the wall surface 3a side of the hoistway 3. By the buffer mechanism 25 by these, the spring 21 contracts when the holding member 8 holding the rotating body 7 rotates in the direction of the car 1.

ここで、図３に回転体７の詳細を示す。回転体７は円筒形状の第１のローラー１１と第１のローラー１１の内径より外形が小さい円筒形状の第２のローラー１２を備えており、第１のローラー１１に第２のローラー１２を遊挿している。また、第２のローラー１２の遊挿する深さを変えることで回転体７の円筒方向の長さを変えることができる。 Here, the detail of the rotary body 7 is shown in FIG. The rotating body 7 includes a cylindrical first roller 11 and a cylindrical second roller 12 whose outer shape is smaller than the inner diameter of the first roller 11, and the second roller 12 is allowed to play on the first roller 11. It is inserted. In addition, the length of the rotating body 7 in the cylindrical direction can be changed by changing the depth to which the second roller 12 is loosely inserted.

第１のローラー１１は、先端側が開口されて円筒内が空洞となっており、保持部材８への取付け側にローラー軸１３の軸部より少し大きな孔１４ａを有するブッシュ１４が嵌装されている。そして、ローラー軸１３が、先端部から挿入されて孔１４ａに挿通し、止め具１６がブッシュ１４の端面１４ｂと隙間を保って装着されて回転自在に保持されている。第２のローラー１２は、先端側にローラー軸１３が挿通可能な孔１５ａの形成された栓１５が嵌装されており、保持部材８への取付け側は孔１４ａを有するブッシュ１４が嵌装されている。そして、ローラー軸１３が、先端部から挿入されて孔１４ａに挿通し、止め具１６がブッシュ１４の端面１４ｂと隙間を保って装着されて回転自在に保持されている。これらにより図２に示すように、回転体７は、ローラー軸１３が保持部材８に保持されて、保持部材８に回転自在に保持される。 The first roller 11 is open at the tip side and has a hollow inside the cylinder, and a bush 14 having a hole 14 a slightly larger than the shaft portion of the roller shaft 13 is fitted on the attachment side to the holding member 8. . The roller shaft 13 is inserted from the tip and inserted into the hole 14a, and the stopper 16 is mounted with a clearance from the end surface 14b of the bush 14 and is rotatably held. The second roller 12 is fitted with a stopper 15 formed with a hole 15a through which the roller shaft 13 can be inserted on the tip side, and a bush 14 having a hole 14a is fitted on the mounting side to the holding member 8. ing. The roller shaft 13 is inserted from the tip and inserted into the hole 14a, and the stopper 16 is mounted with a clearance from the end surface 14b of the bush 14 and is rotatably held. As a result, as shown in FIG. 2, the rotating body 7 is rotatably held by the holding member 8 with the roller shaft 13 held by the holding member 8.

次に、制御ケーブル４が回転体７を押圧した時のエレベータ制御ケーブルの保護装置６の動作について図４を用いて説明する。
かご１が最下階に近づいてかご１の底部と制御ケーブル４との距離が近くなり、制御ケーブル４が矢印Ａ方向（かご１方向）に移動して、上側（中間部）あるいは下側（先端部）の回転体７を押圧した時に保持部材８がかご１方向に移動（回動）する。この時、緩衝機構２５のバネ２１が縮んで、制御ケーブル４が回転体７に接触して押圧した時の衝撃エネルギーを吸収する。なお、制御ケーブル４が回転体７から離れるとバネ２１が昇降路３の壁面３ａ方向に伸び、保持部材８が押圧される前の位置に戻る。 Next, the operation of the elevator control cable protection device 6 when the control cable 4 presses the rotating body 7 will be described with reference to FIG.
As the car 1 approaches the lowermost floor, the distance between the bottom of the car 1 and the control cable 4 decreases, and the control cable 4 moves in the direction of arrow A (the direction of the car 1) to move upward (intermediate) or lower ( When the rotating body 7 at the front end portion is pressed, the holding member 8 moves (rotates) in the direction of the car 1. At this time, the spring 21 of the buffer mechanism 25 contracts and absorbs impact energy when the control cable 4 comes into contact with the rotating body 7 and is pressed. When the control cable 4 is separated from the rotating body 7, the spring 21 extends in the direction of the wall surface 3a of the hoistway 3 and returns to the position before the holding member 8 is pressed.

このようなエレベータ制御ケーブルの保護装置６によれば、一端をかご１の底部１ａから吊設し他端を昇降路３に設けた中継点５に吊設して昇降路３の壁面３ａに沿って垂下した制御ケーブル４の壁面３ａ側に対向して、制御ケーブル４のかご１への接触を防ぐ回転体７を保持部材８により回転自在に保持してかご１の底部１ａに配設したエレベータ制御ケーブルの保護装置６において、かご１の底部１ａに、保持部材８を回動可能に保持する固定部材２４と、保持部材８に回動可能に連結してかご１方向へ伸縮する緩衝機構２５と、を備えているので、制御ケーブル４が回転体７に接触して回転体７を押圧した時の衝撃を緩衝機構２５のバネ２１がかご１方向に縮んで吸収することにより、騒音の発生を防ぐことができる。 According to such an elevator control cable protection device 6, one end is suspended from the bottom 1 a of the car 1, and the other end is suspended from the relay point 5 provided in the hoistway 3, along the wall surface 3 a of the hoistway 3. An elevator which is disposed on the bottom 1a of the car 1 so as to face the wall surface 3a of the hanging control cable 4 and prevent the control cable 4 from coming into contact with the car 1 so as to be rotatably held by a holding member 8. In the control cable protection device 6, a fixing member 24 that rotatably holds the holding member 8 at the bottom 1 a of the car 1, and a buffer mechanism 25 that is rotatably connected to the holding member 8 and extends and contracts in the direction of the car 1. Therefore, when the control cable 4 comes into contact with the rotator 7 and presses the rotator 7, the spring 21 of the buffer mechanism 25 contracts and absorbs in the direction of the car 1 to generate noise. Can be prevented.

そして、緩衝機構２５は、保持部材８に対向した孔２３ａを有しかご１の底部１ａに配設した金具２３と、一端部が保持部材８に連結され他端部が孔２３ａに挿通されたバネロッド２０と、バネロッド２０に装着されたバネ２１と、孔２３ａに挿入されたバネロッド２０の他端部側に固定されたストッパ２２と、を備えているので簡単な構成で緩衝機能を得ることが出来る。 The shock absorber 25 has a hole 23a facing the holding member 8 and a metal fitting 23 disposed on the bottom 1a of the car 1, one end connected to the holding member 8, and the other end inserted through the hole 23a. Since the spring rod 20, the spring 21 attached to the spring rod 20, and the stopper 22 fixed to the other end side of the spring rod 20 inserted into the hole 23a are provided, a buffering function can be obtained with a simple configuration. I can do it.

さらに、回転体７を上下方向に少なくとも２つ並設して備えているので、かご１が最下階に近づいてかご１の底部１ａと制御ケーブル４との距離が近くなった時に、下側（先端部）の回転体７に制御ケーブル４が接触して押圧するので、制御ケーブル４があまり曲がっていない状態でかご１との接触を防ぐことで、制御ケーブル４に急激な負荷を与えなくてすむ。 Further, since at least two rotating bodies 7 are arranged in the vertical direction, when the car 1 approaches the lowest floor and the distance between the bottom 1a of the car 1 and the control cable 4 becomes short, the lower side Since the control cable 4 comes into contact with and presses against the rotating body 7 at the (tip portion), the control cable 4 is prevented from coming into contact with the car 1 in a state where the control cable 4 is not bent so much, so that a sudden load is not applied to the control cable 4. Tesumu.

また、回転体７は円筒形状の第１のローラー１１と第１のローラー１１の内径より外形が小さい円筒形状の第２のローラー１２を備えており、第１のローラー１１に第２のローラー１２を遊挿した構成としているので、第２のローラー１２の遊挿する深さを変えて円筒方向の長さを変えることが可能であり、制御ケーブル４の幅や本数が変わった時もそれらに応じた長さに変えることが出来る。 The rotating body 7 includes a cylindrical first roller 11 and a cylindrical second roller 12 whose outer shape is smaller than the inner diameter of the first roller 11, and the first roller 11 includes the second roller 12. Therefore, it is possible to change the length of the cylindrical direction by changing the depth of insertion of the second roller 12, and when the width and number of the control cables 4 change, It can be changed according to the length.
