Portable exercising apparatus

Abstract

A portable exercising apparatus includes a first frame member, a second frame member, a first tube perpendicularly and fixedly connected to the first frame member, a second tube perpendicularly and fixedly connected to the second frame member and slidably inserted into the first tube and defining with the first tube an air chamber, an air valve mounted in the first tube in communication with the air chamber and the atmosphere, and two elastic members connected between the first frame member and the second frame member at two sides of the first tube and the second tube.

1 . A portable exercising apparatus comprising:
 a first frame member;   a second frame member;   a first tube having a first end fixedly connected to said first frame member and an opening at a second end thereof;   a second tube having a first end fixedly connected to said second frame member and a second end inserted through the opening of said first tube into the inside of said first tube such that an air chamber is defined inside said first tube;   an air valve mounted in said first tube in communication with said air chamber and the atmosphere; and   at least one elastic member fixedly connected between said first frame member and said second frame member.   
   
   
       2 . The portable exercising apparatus as claimed in  claim 1 , wherein said first frame member has a locating hole, which receives the first end of said first tube. 
   
   
       3 . The portable exercising apparatus as claimed in  claim 1 , wherein said second frame member has a locating hole, which receives the first end of said second tube. 
   
   
       4 . The portable exercising apparatus as claimed in  claim 1 , wherein said first tube has a transverse through hole, which accommodates said air valve. 
   
   
       5 . The portable exercising apparatus as claimed in  claim 1 , wherein said at least one elastic member is formed of a carbon fiber rod member. 
   
   
       6 . The portable exercising apparatus as claimed in  claim 5 , wherein said first frame member has a mounting hole for receiving a first end of the carbon fiber rod member. 
   
   
       7 . The portable exercising apparatus as claimed in  claim 6 , wherein said second frame member has a mounting hole for receiving a second end of the carbon fiber rod member. 
   
   
       8 . The portable exercising apparatus as claimed in  claim 1 , further comprising at least one grip respectively mounted on said at least one elastic member. 
   
   
       9 . The portable exercising apparatus as claimed in  claim 1 , the portable exercising apparatus has two said elastic members, which are connected between said first frame member and said second frame member at two sides of and in parallel to said first tube and said second tube.
