Benefits of technology

"The present invention provides an exercising elastic pull cord that has several technical effects. Firstly, the elastic inner tube of the pull cord is not deformed by the tensile action, which ensures that the handgrip is securely attached to the pull cord and prevents it from detaching. Secondly, the fabric outer layer coated around the elastic inner tube prevents the elastic inner tube from being rubbed by the handgrip, which improves the lifetime of the pull cord. Lastly, the elastic inner tube is coated by the fabric outer layer to prevent accidental springing outward and to protect the user's safety when using the pull cord."

Problems solved by technology

Further, the elastic pull cord body 41 will spring outward accidentally when being broken or worn out, thereby causing danger to a user's when using the exercising elastic pull cord.

Embodiment Construction

[0020] Referring to the drawings and initially to FIG. 1, an exercising elastic pull cord 1 in accordance with the preferred embodiment of the present invention comprises an elastic pull cord body 11 having an elastic inner tube 111, and a fabric outer layer 112 coated around an outer periphery of the elastic inner tube 111. The fabric outer layer 112 of the elastic pull cord body 11 is formed by a cylinder knitting machine. The elastic inner tube 111 of the elastic pull cord body 11 has an elastic coefficient greater than that of the fabric outer layer 112.

[0021] Referring to FIGS. 1-4, the elastic pull cord body 11 has two distal ends each provided with a handgrip 12, an urging body 2, and a contraction sleeve 3.

[0022] The handgrip 12 is pivotally attached to the respective distal end of the elastic pull cord body 11 and has an end face having an inside formed with a catch flange 121 rested on the contraction sleeve 3.

[0023] The urging body 2 is attached to the respective dista...

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.

Description

BACKGROUND OF THE INVENTION [0001] 1. Field of the Invention [0002] The present invention relates to an exercising device, and more particularly to an exercising elastic pull cord. [0003] 2. Description of the Related Art [0004] A conventional exercising elastic pull cord 4 in accordance with the prior art shown in FIGS. 5-8 comprises an elastic pull cord body 41 having two distal ends each provided with a handgrip 42, an urging body 5, and a sleeve 6. The handgrip 42 has an end face having an inside formed with a catch flange 421 rested on the sleeve 6. The urging body 5 is inserted into the elastic pull cord body 41 to press the elastic pull cord body 41 and the sleeve 6 outward so that the sleeve 6 has a protruding stop portion 61 rested on the catch flange 421 of the handgrip 42 to secure the sleeve 6 to the handgrip 42, thereby preventing the sleeve 6 from being detached from the handgrip 42. [0005] When the handgrip 42 is moved outward relative to the elastic pull cord body 41...
