Abstract: An elastic cable structure includes an elastic cable. The elastic cable includes a plurality of strands of elastic tubes, and the strands of elastic tubes are twisted mutually. Each of the elastic tubes includes an outer layer and a plurality of latex bars mounted in and covered by the outer layer. Thus, the latex bars are covered by the outer layer so that the latex bars will not directly contact the user's skin and will not cause allergic reactions to the user. In addition, the latex bars are completely covered by the outer layer so that when the latex bars are broken due to an excessive force, the latex bars are restricted by the outer layer and will not be sprung outward.

Abstract: A pet strap assembly includes a drawing unit and a pulling unit detachably connected with the drawing unit. The drawing unit includes an elastic strap. The elastic strap includes an outer layer, at least one inner layer mounted in and surrounded by the outer layer and a plurality of resilient strips mounted in and surrounded by the at least one inner layer. Thus, the elastic drawing unit provides an elastic buffering effect to the user by the elastic action of the resilient strips to reduce the reaction applied by the pet on the user's hand to the minimum extent, thereby preventing the user's wrist from being hurt when the pet is running violently.

Abstract: A pet strap includes a pulling unit, a locking unit, and an elastic drawing mounted between the pulling unit and the locking unit and including an elastic inner tube and a weaving outer layer mounted on a surface of the inner tube. Thus, the elastic drawing unit provides a buffering effect to the user to reduce the reaction applied by the pet on the user's hand, thereby preventing the user's wrist from being hurt when the pet is running violently. In addition, the weaving outer layer is enclosed around the inner tube, so that when the inner tube is broken due to an excessive reaction, the inner tube will not being sprung outward, thereby preventing the user from being hurt by the broken inner tube.

Abstract: An exercising elastic pull cord includes an elastic pull cord body having an elastic inner tube, and a fabric outer layer coated around an outer periphery of the elastic inner tube. The elastic pull cord body has two distal ends each provided with a handgrip, an urging body, and a contraction sleeve. Thus, the elastic inner tube of the elastic pull cord body is not deformed by the tensile action of the elastic pull cord body, so that the contraction sleeve mounted around the elastic pull cord body is secured to the handgrip closely, thereby preventing the handgrip from being detached from the respective distal end of the elastic pull cord body.

Abstract: A pull cord for an exercising device includes an elastic cord body, and an outer layer mounted on an outer surface of the cord body. Thus, the outer layer is formed by the knitting yarns which are knitted onto and enclosed around the outer surface of the cord body so as to protect the cord body efficiently, so that the cord body does not directly contact a user's hands, thereby preventing the cord body from being worn out, and thereby enhancing the lifetime of the cord body. In addition, when the cord body is broken due to tensile action during a long-term utilization, the broken cord body is enclosed in the outer layer, thereby preventing the broken cord body from hurting the user's body.
