このようなエレべ一夕装置においては、 駆動シーブ 2とかご吊り車 9及び釣合 おもり吊り車 1 0との間で主索 5が捻られるため、 ロープ本体 1 1の幅方向の位 置によって子纏 1 2の幾何学的な長さが異なり、 これにより子縛 1 2の負担荷重 もロープ本体 1 1の幅方向の位置によって異なってしまう。 In such an elevator apparatus, the main rope 5 is twisted between the driving sheave 2 and the car suspension wheel 9 and the counterweight suspension wheel 10, so that the position of the rope main body 11 in the width direction is changed. The geometric lengths of the child body 1 and 2 are different, and this causes the load Also depends on the position of the rope body 11 in the width direction.
このような負担荷重の違いにより子繙 1 2の張力に差が生じると、 被覆体 1 3 の互いに隣接する子繙 1 2間の部分にはせん断力が作用する。 そして、 接着剤 1 5の剥離、 被覆体 1 3の破損、 及び負担荷重が大きい子緙 1 2の素線 1 4の疲労 断線が生じる恐れがある。  When a difference occurs in the tension of the sub-references 12 due to such a difference in the burden load, a shear force acts on a portion between the adjacent sub-references 12 of the cover 13. Then, the adhesive 15 may be peeled off, the covering 13 may be damaged, and the wires 14 of the strand 12 having a large load may be broken.
これに対し、 この実施の形態 1では、 被覆体 1 3に多数の隙間 1 3 aが設けら れているので、 被覆体 1 3による子耩 1 2の拘束力が低減され、 ロープ本体 1 1 の幅方向への子緙 1 2の動きがある程度許容される。  On the other hand, in the first embodiment, since a large number of gaps 13 a are provided in the covering 13, the restraining force of the child 12 by the covering 13 is reduced, and the rope body 1 1 The movement of the child 緙 12 in the width direction is allowed to some extent.
従って、 接着剤 1 5の剥離、 被覆体 1 3の破損、 及び素線 1 4の疲労断線が抑 制され、 安定した強度を確保できるとともに、 長寿命化を図ることができる。 即 ち、 特定の子繙 1 2に損傷が集中しないため、 主索 5全体としての寿命を延ばす ことができる。  Therefore, peeling of the adhesive 15, breakage of the covering 13, and fatigue disconnection of the strand 14 are suppressed, and stable strength can be ensured and the life can be extended. That is, since the damage is not concentrated on a specific child ref 1, the life of the main rope 5 as a whole can be extended.
また、 口一プ本体 1 1の長手方向に互いに隣接する隙間 1 3 aの間隔、 即ち結 合部 1 3 cの長さにより、 被覆体 1 3による子縛 1 2の拘束力を容易に設定する ことができる。  In addition, the restraining force of the binding 13 by the covering 13 can be easily set by the distance between the gaps 13 a adjacent to each other in the longitudinal direction of the mouthpiece body 11, that is, the length of the joint 13 c. can do.
さらに、 隙間 1 3 aに応力緩和部 1 3 bが設けられているので、 隙間 1 3 aの 長手方向両端部での応力集中が緩和され、 応力集中による亀裂の発生及び進展を 抑制することができる。  Furthermore, since the gap 13a is provided with the stress relaxation portion 13b, stress concentration at both ends in the longitudinal direction of the gap 13a is reduced, and the generation and propagation of cracks due to the stress concentration can be suppressed. it can.
さらにまた、 ロープ本体 1 1の幅方向に互いに隣接する隙間 1 3 aは、 ロープ 本体 1 1の長手方向に互いに半ピッチずつずらして配置されているので、 結合部 1 3 cも口一プ本体 1 1の長手方向に互いにずらして配置され、 ロープ本体 1 1 の長手方向について強度を均等化することができる。 実施の形態 2 .  Furthermore, since the gaps 13 a adjacent to each other in the width direction of the rope body 11 are shifted by half a pitch from each other in the longitudinal direction of the rope body 11, the connecting portion 13 c is also a mouth-opening body. The rope bodies 11 are arranged so as to be shifted from each other in the longitudinal direction, so that the strength can be equalized in the longitudinal direction of the rope body 11.

Each unit core 25 has a plurality of steel strands 26. The strands 26 are twisted in parallel with each other.
芯材 2 4の材料としては、 例えばポリプロピレン樹脂、 ポリエチレン樹脂又は ビニール等の熱可塑性樹脂、 若しくは高強度のァラミ ド繊維又はポリプロピレン 繊維等の合成樹脂繊維を高密度に撚り合わせたものが使用できる。  As the material of the core material 24, for example, a thermoplastic resin such as a polypropylene resin, a polyethylene resin or vinyl, or a high-strength synthetic resin fiber such as an aramid fiber or a polypropylene fiber can be used.
各単位子緙 2 5の少なくとも外周部には、 被覆体 1 3と一体化させるために接 着剤 （図示せず） が塗布されている。  At least the outer peripheral portion of each unit element # 25 is coated with a bonding agent (not shown) in order to integrate it with the cover 13.
織布体 2 3は、 例えばァラミ ド樹脂繊維又はガラス繊維等の高強度繊維を布状 に織り上げたものである。 また、 高強度繊維は、 単繊維のまま、 又は複数の単繊 維の集合体として織られている。 織布体 2 3は、 隣接する子繙 2 2間のみに配置 してもよい。  The woven fabric body 23 is made by weaving high-strength fibers such as an aramide resin fiber or a glass fiber into a cloth. The high-strength fiber is woven as a single fiber or as an aggregate of a plurality of single fibers. The woven fabric 23 may be arranged only between the adjacent children 22.
被覆体 1 3には、 複数の隙間 1 3 aが設けられている。 実施の形態 3では、 ロープ本体 1 1の幅方向に互いに隣接する隙間 1 3 aは、 ロープ本体 2 1の長手 方向の同じ位置に並べて配置されている。 このような構成によれば、 芯材 2 4と 3本の単位子繙 2 5とにより子繙 2 2を 構成したので、 より細い素線 2 6を用いることができ、 適用する綱車の径を小さ くすることができる。 The cover 13 has a plurality of gaps 13a. In the third embodiment, the gaps 13a adjacent to each other in the width direction of the rope main body 11 are arranged at the same position in the longitudinal direction of the rope main body 21. According to such a configuration, since the core member 24 and the three unit elements reference 25 constitute the child reference 22, a thinner wire 26 can be used, and the diameter of the sheave to be applied is Can be reduced.
また、 被覆体 1 3に織布体 2 3を埋設したので、 被覆体 1 3の強度を高めるこ とができ、 隙間 1 3 aを設けたことによる被覆体 1 3の強度低下を防止すること ができる。 また、 補強材としての繊布体 2 3を用いたので、 被覆体 1 3の引張強 度は高められるが、 せん断方向や圧縮方向への補強効果は低く、 子縛 2 2の動き が抑制されるのが防止される。  In addition, since the woven fabric body 23 is embedded in the covering body 13, the strength of the covering body 13 can be increased, and the strength of the covering body 13 due to the provision of the gap 13a can be prevented. Can be. In addition, since the woven fabric 23 is used as a reinforcing material, the tensile strength of the cover 13 can be increased, but the reinforcing effect in the shear direction and the compression direction is low, and the movement of the binding 22 is suppressed.
