Safety Strap

Abstract

A safety strap has an outer layer, an inner layer disposed in the outer layer and a plurality of interlace strands. The inner layer has a plurality of warp strand bundles and a plurality of first weft strands woven with each other. Each of the warp strand bundles has more than one first warp strand. The outer layer is woven with a plurality of second warp strands and a plurality of second weft strands. The interlace strands continuously intertwine with the second weft strands and the first weft strands.

Claims

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENT

[0018] First, please refer to FIG. 1-FIG. 4. A safety strap 10 comprises an outer layer 12 an inner layer 11 disposed in the outer layer 12 and a plurality of interlace strands 20. The inner layer 11 has a plurality of warp strand bundles 111 and a plurality of first weft strands 112 woven with each other. Each of the warp strand bundle 111 has more than one first warp strand 1111. The outer layer 12 is woven with a plurality of second warp strands 121 and a plurality of second weft strands 122. The interlace strands 20 continuously intertwine with the second weft strands 122 and the first weft strands 112. With the interlace strands 20, the inner layer 11 and the outer layer 12 are combined together and a reinforcement effect is provided to the inner layer 11.

[0019] Furthermore, the warp strand bundle 111 are woven with three first warp strands 1111.

[0020] Moreover, the warp strand bundles 111 are woven with three first warp strands 1111, two of the three first warp strands 1111 respectively pass several first weft strands 112 from above and from below, and another first warp strand 1111 continuously passes around the first weft strand 112.

[0021] Furthermore, the first warp strand 1111, the second warp strand 121, the first weft strand 112 and the second weft strand 122 are multifilament polymer strands, which are composed of UV-resistant liquid crystal aromatic polyester fibers, also known as LCP liquid crystal polymer aromatic polyester fiber.

[0022] In addition, the outer layer 12 is completely wrapped around the inner layer 11.

[0023] For actual operation, the safety strap 10 is equipped with the anti-fall clothing or the anti-fall belt on a user's body, so that the anti-fall clothing or the anti-fall belt can be connected with the anti-fall device 30 via the safety strap 10, as shown in FIG. 1, to ensure the safety of personnel working at heights or activities. If the user accidentally falls during the operation or the second warp strand 121 of the outer layer 12 is worn out and damaged due to friction from the wall, the support or the iron sheet of the building, as shown in FIG. 5 and FIG. 6, the warp strand bundle 111 can still be tightened continuously through the interlace strands 20, and the first warp strands 1111 of the warp strand bundle 111 are not spread out at the damaged opening, therefore, the safety strap 10 can be kept in a tightened and not loose state because the warp strand bundle 111 is still in a tightened and not loose state and will not break, as shown in FIG. 7. Also, the safety strap 10 has the tightening and strengthening effect of the inner layer 11, so its structural strength can be significantly improved.

[0024] Although the present invention has been explained in relation to its preferred embodiment, it is to be understood that many other possible modifications and variations can be made without departing from the spirit and scope of invention as hereinafter claimed.
