1. Field of the Invention
The present invention relates to a cord structure and, more particularly, to an elastic cable structure available for an elastic exercising device (such as a chest pull) or a pet drawing rope.
2. Description of the Related Art
A conventional elastic cable structure in accordance with the prior art shown in
In accordance with the present invention, there is provided an elastic cable structure comprising 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 at least one latex bar mounted in and covered by the outer layer.
Preferably, each of the strands of elastic tubes includes at least one elastic tube.
Preferably, each of the elastic tubes includes a plurality of latex bars, and the number of the latex bars is changed to fit a needed elastic force of the elastic cable.
Preferably, the outer layer of each of the elastic tubes is made by weaving.
Alternatively, the outer layer of each of the elastic tubes is made by stitching.
Preferably, the elastic cable structure further comprises two handles mounted on two opposite ends of the elastic cable. Each of the two opposite ends of the elastic cable is provided with a locking member, and each of the handles is provided with a mounting hole for mounting the respective locking member of the elastic cable.
Alternatively, the elastic cable structure further comprises a handle mounted on a first end of the elastic cable, and a locking hook mounted on a second end of the elastic cable and connected with a collar of a pet.
According to the primary advantage of the present invention, the latex bars enhance the tensile resistance, resilience and strength of the elastic cable.
According to another advantage of the present invention, 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.
According to a further advantage of the present invention, the outer layer has different colors to enhance the aesthetic quality of the elastic cable.
According to a further advantage of the present invention, 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, so as to assure the user's safety of usage.
Further benefits and advantages of the present invention will become apparent after a careful reading of the detailed description with appropriate reference to the accompanying drawings.
Referring to the drawings and initially to
The elastic cable 10 includes a plurality of strands of elastic tubes 11, and the strands of elastic tubes 11 are twisted mutually. Each of the strands of elastic tubes 11 includes at least one elastic tube 11. Each of the elastic tubes 11 includes an outer layer 112 and at least one latex bar 111 mounted in and covered by the outer layer 112. Each of the elastic tubes 11 includes a plurality of latex bars 111, and the number of the latex bars 111 can be changed to fit the needed elastic force of the elastic cable 10 according to the user's requirement. The outer layer 112 of each of the elastic tubes 11 is preferably made by weaving or stitching.
In the preferred embodiment of the present invention, the elastic cable 10 includes four strands of elastic tubes 11, each of the strands of elastic tubes 11 includes two elastic tubes 11, and each of the elastic tubes 11 includes four latex bars 111.
The handles 20 are mounted on two opposite ends of the elastic cable 10. Each of the two opposite ends of the elastic cable 10 is provided with a locking member 12, and each of the handles 20 is provided with a mounting hole 21 for mounting the respective locking member 12 of the elastic cable 10.
In assembly, the outer layer 112 covers the latex bars 111 to form each of the elastic tubes 11. Then, a first end of the elastic cable 10 formed by the elastic tubes 11 is mounted in the respective locking member 12. Then, the elastic tubes 11 are divided into four strands, and the four strands of elastic tubes 11 are twisted mutually to form the elastic cable 10. Then, a second end of the elastic cable 10 is mounted in the respective locking member 12. Finally, the locking member 12 of each of the two opposite ends of the elastic cable 10 is mounted in the mounting hole 21 of each of the handles 20, so that the elastic cable 10 is fixed between the handles 20. Thus, the elastic cable structure functions as a chest pull.
Referring to
Accordingly, the latex bars 111 enhance the tensile resistance, resilience and strength of the elastic cable 10. In addition, the latex bars 111 are covered by the outer layer 112 so that the latex bars 111 will not directly contact the user's skin and will not cause allergic reactions to the user. Further, the outer layer 112 has different colors to enhance the aesthetic quality of the elastic cable 10. Further, the latex bars 111 are completely covered by the outer layer 112 so that when the latex bars 111 are broken due to an excessive force, the latex bars 111 are restricted by the outer layer 112 and will not be sprung outward, so as to assure the user's safety of usage.
Although the invention has been explained in relation to its preferred embodiment(s) as mentioned above, it is to be understood that many other possible modifications and variations can be made without departing from the scope of the present invention. It is, therefore, contemplated that the appended claim or claims will cover such modifications and variations that fall within the true scope of the invention.
