  • Each of the strands 12 has a plurality of steel wires 14 .
  • the wires 14 are laid parallel to each other (See Japanese Industrial Standards (JIS) G 3525 12.2 b). It is preferable for the cross-sectional construction of the strands 12 to be a Warrington type as defined in JIS G 3525.
  • the coating body 13 is composed of thermoplastic ether-based polyurethane resin, for example.
  • An adhesive 15 is applied to at least an outer peripheral portion of each of the strands 12 to integrate the strands 12 with the coating body 13. That is, the strands 12 and the coating body 13 are bonded to each other by means of the adhesive 15.

  • the constraining force of the coating body 13 on the strands 12 is reduced because a large number of gaps 13a are disposed on the coating body 13, permitting a certain amount of movement of the strands 12 in a width direction of the rope main body 11.
  • the constraining force of the coating body 13 on the strands 12 can easily be set by means of the distance between gaps 13a that are adjacent to each other in the longitudinal direction of the rope main body 11, in other words, by the length of the joining portions 13c.
  • the stress alleviating portions 13b are disposed in the gaps 13a, concentration of stress at the either longitudinal end portion of the gaps 13a is alleviated, enabling the occurrence and development of cracking due to the concentration of stress to be suppressed.
  • gaps 13a that are adjacent to each other in a width direction of the rope main body 11 are disposed so as to be offset by half a pitch from each other in the longitudinal direction of the rope main body 11, the joining portions 13c are also disposed so as to be offset from each other in the longitudinal direction of the rope main body 11, enabling strength to be made uniform in the longitudinal direction of the rope main body 11.
  • Figure 5 is a cross section of an elevator rope according to Embodiment 2 of the present invention.
  • high-strength fibers 16 functioning as a reinforcing material are mixed uniformly into a coating body 13.
  • Aramid resin fibers or glass fibers, etc. are used for the high-strength fibers 16, for example.
  • the high-strength fibers 16 may be mixed into the coating body 13 as unmodified single fibers, or as a composite body constituted by a plurality of single fibers. The rest of the construction is similar to that of Embodiment 1.
  • the strength of the coating body 13 can be increased, enabling strength degradation of the coating body 13 due to the disposing of the gaps 13a to be prevented. Furthermore, because high-strength fibers 16 functioning as a reinforcing material are used, tensile strength in the coating body 13 is increased, but stiffening effects in a shearing direction and a compressive direction are low, preventing movement of the strands 12 from being suppressed.
  • Figure 6 is a cross section of an elevator rope according to Embodiment 3 of the present invention
  • Figure 7 is a cross section taken along line VII - VII in Figure 6 .
  • a belt-shaped rope main body 21 has: seven strands 22 disposed at a distance from each other in a width direction of the rope main body 21; a coating body 13 made of resin for covering and integrating the strands 22; and a woven cloth body 23 embedded in the coating body 13 so as to surround the strands 22.
  • Each of the strands 22 respectively includes: a core material 24 made of resin extending in a longitudinal direction of the rope main body 21; and three unit strands 25 disposed around the core material 24 and laid together with the core material 24.
  • Each of the unit strands 25 has a plurality of steel wires 26. The wires 26 are laid parallel to each other.
  • thermoplastic resin such as polypropylene resin, polyethylene resin, or vinyl, etc., or synthetic resin fibers such as high-strength aramid fibers or polypropylene fibers, etc., laid together at a high density, for example, can be used for the material of the core material 24.
  • Adhesive (not shown) is applied to at least an outer peripheral portion of each of the unit strands 25 in order to integrate them with the coating body 13.
  • the woven cloth body 23 is constituted by high-strength fibers such as aramid resin fibers or glass fibers, etc., woven into a cloth form, for example. Furthermore, the high-strength fibers 16 may be woven as unmodified single fibers, or as composite bodies constituted by a plurality of single fibers. The woven cloth body 23 may also be dispose only between adjacent strands 22.
  • gaps 13a are disposed in the coating body 13.
  • gaps 13a that are adjacent to each other in a width direction of the rope main body 11 are disposed so as to line up in similar positions in a longitudinal direction of the rope main body 21.
  • the strands 22 are constituted by a core material 24 and three unit strands 25, slenderer wires 26 can be used, enabling reductions in a diameter of a sheave to which the present invention is applied.
  • the strength of the coating body 13 can be increased, enabling strength degradation of the coating body 13 due to the disposing of the gaps 13a to be prevented. Furthermore, because a woven cloth body 23 functioning as a reinforcing material is used, tensile strength in the coating body 13 is increased, but stiffening effects in a shearing direction and a compressive direction are low, preventing movement of the strands 22 from being suppressed.
  • the woven cloth body 23 is not divided up finely by the gaps 13a, enabling reinforcing effects from the woven cloth body 23 to be increased.
  • gaps 13a passing through a rope main body 11 or 21 are shown, but the gaps may also be apertures opening onto only one side of the rope main body, or may also be hollow gaps having no openings.
  • the gaps 13a may be assumed to be air gaps, but the gaps may also be filled with a material differing from that of the coating body. However, it is undesirable for the material with which the gaps are filled to hinder movement of the strands.
  • an elevator apparatus using a two-to-one (2:1) roping method is shown, but the elevator rope according to the present invention can also be applied to elevator apparatuses using other methods such as a one-to-one (1:1) roping method, etc., for example.
  • a one-to-one (1:1) roping method etc.
  • particularly superior effects are exhibited when it is applied to elevator apparatuses in which a twist occurs in the rope main body.
