れる。<B> Impact Absorbing Fence Rope Material FIG. 1 is a perspective view of the rope material 1 and FIG. 2 is an enlarged sectional view thereof. There are multiple (3 bundles) of rope materials 1 for shock absorbing fences.
The point that the strand bundles 2 of No. 1 are twisted together is the same as the conventional one, but in the present invention, the reinforcing wire 3 is additionally woven into each spiral groove 11 formed continuously between the strands 2. Composed.
【００１４】複数の素線２１をより合わせて構成される
素線束２や、複数の素線束２の編成方法等については従

に機能する。The reinforcing wire 3 is a well-known steel wire that is resistant to tension and wear, and the diameter of the reinforcing wire 3 is from the axis of a plurality of wire bundles 2 constituting the rope material 1 to that of the wire bundle 2 as shown in FIG. The diameter is inscribed in a virtual circle whose radius is the distance to the outermost peripheral surface. That is, the reinforcing wire 3 functions so that the cross-sectional diameter of the rope material 1 maintains the same diameter over the entire length and the cross-sectional shape is circular.

平状態に変形することがない。<A> Deformability Since the conventional rope material has a substantially triangular cross-section, when pressed, the filament bundles are displaced and deformed into a flat shape. By accommodating the reinforcing wire 3 in each of the grooves 11, the reinforcing wire 3 prevents the strands of wire 2 from being displaced, and the reinforcing wire 3 itself is also restrained by the strands of wire 2 to prevent displacement. Therefore, even if a considerably large flattening force is applied to the rope material 1, the cross-sectional shape can be maintained in a substantially circular shape, and the rope material is not deformed into a flattened state unlike the conventional case.

なる。<B> Sliding property In FIG. 5, the rope member 1 has a circular cross section, and the shape is the same over the entire length of the rope member 1. Therefore, even if the impact absorbing device 6 grips the rope material 1, the rope material 1 can maintain a substantially uniform diameter without a diameter difference.
The sliding resistance of the sliding rope material 1 becomes constant due to the tension acting on the rope material 1 exceeding the gripping force. Further, if the gripping force of each rope member 1 is constant and the tension application timings are the same, all the rope members 1 will start sliding simultaneously.
