Exercising elastic pull cord

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.

1 . An exercising elastic pull cord, comprising: 
 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.    
   
   
       2 . The exercising elastic pull cord in accordance with  claim 1 , wherein the elastic inner tube of the elastic pull cord body has an elastic coefficient greater than that of the fabric outer layer.  
   
   
       3 . The exercising elastic pull cord in accordance with  claim 1 , wherein the elastic pull cord body has two distal ends each provided with a handgrip, an urging body, and a contraction sleeve, wherein the contraction sleeve is attached to the respective distal end of the elastic pull cord body and mounted around an outer periphery of the fabric outer layer of the elastic pull cord body.  
   
   
       4 . The exercising elastic pull cord in accordance with  claim 3 , wherein the contraction sleeve is made of a material that is contracted when being heated.  
   
   
       5 . The exercising elastic pull cord in accordance with  claim 3 , wherein the contraction sleeve has an inner wall provided with a gel layer coated around the outer periphery of the fabric outer layer of the elastic pull cord body.  
   
   
       6 . The exercising elastic pull cord in accordance with  claim 5 , wherein the outer periphery of the fabric outer layer of the elastic pull cord body has a plurality of meshes combined with the gel layer of the contraction sleeve integrally.  
   
   
       7 . The exercising elastic pull cord in accordance with  claim 6 , wherein when the gel layer of the contraction sleeve is heated to form a liquid state, the gel layer of the contraction sleeve is infiltrated into and mixed with the meshes of the fabric outer layer of the elastic pull cord body.  
   
   
       8 . The exercising elastic pull cord in accordance with  claim 6 , wherein the gel layer of the contraction sleeve and the meshes of the fabric outer layer of the elastic pull cord body are bonded together, so that the contraction sleeve and the fabric outer layer of the elastic pull cord body are combined integrally.  
   
   
       9 . The exercising elastic pull cord in accordance with  claim 5 , wherein the gel layer of the contraction sleeve is disposed at a liquid state when being heated.  
   
   
       10 . The exercising elastic pull cord in accordance with  claim 3 , wherein: 
 the handgrip is pivotally attached to the respective distal end of the elastic pull cord body and has an end face having an inside formed with a catch flange rested on the contraction sleeve;    the urging body is attached to the respective distal end of the elastic pull cord body and inserted into the elastic inner tube of the elastic pull cord body to press the elastic pull cord body and the contraction sleeve radially outward so that the contraction sleeve has a radially outward extended stop portion rested on the catch flange of the handgrip to secure the contraction sleeve to the handgrip, thereby preventing the contraction sleeve from being detached from the handgrip.    
   
   
       11 . The exercising elastic pull cord in accordance with  claim 1 , wherein the fabric outer layer of the elastic pull cord body is formed by a cylinder knitting machine.  
   
   
       12 . The exercising elastic pull cord in accordance with  claim 3 , wherein when the elastic pull cord body is pulled outward by the handgrip, the elastic inner tube of the elastic pull cord body will not driven by the handgrip to slip toward the tensile direction of the elastic pull cord body from the urging body.  
   
   
       13 . The exercising elastic pull cord in accordance with  claim 3 , wherein the elastic inner tube of the elastic pull cord body is not deformed by a 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.  
   
   
       14 . The exercising elastic pull cord in accordance with  claim 3 , wherein the fabric outer layer of the elastic pull cord body is coated around the elastic inner tube to prevent the elastic inner tube of the elastic pull cord body from being rubbed by the handgrip.
