Grip Exerciser

Abstract

A grip exerciser has a first handle, a second handle, a connecting member and a spring. The first handle and the second handle both have a pivoting portion and a holding portion, a pivot is disposed through the pivoting portions of the first handle and the second handle to assemble the first handle and the second handle together; the first handle further has an escaping space at an inner edge for accepting the connecting member, and the second handle further has a closed surface at an inner edge; the closed surface further has a plurality of positioning protrusions located along a continuous line and capable of engaging with one end of the spring;

What is claimed is: 
     
         1 . A grip exerciser comprising: a first handle, a second handle, a connecting member and a spring; wherein:
 the first handle and the second handle both have a pivoting portion and a holding portion, a pivot is disposed through the pivoting portions of the first handle and the second handle to assemble the first handle and the second handle together; the first handle further has an escaping space at an inner edge for accepting the connecting member, and the second handle further has a closed surface at an inner edge; the closed surface further has a plurality of positioning protrusions located along a continuous line and capable of engaging with one end of the spring;   wherein the connecting member has a connecting column with an enlarged stopper at an end and pivoted in the escaping space, and another end of the spring is sleeved onto the connecting column that is pushed by the stopper.   
     
     
         2 . The grip exerciser as claimed in  claim 1 , wherein the closed surface is an arced surface. 
     
     
         3 . The grip exerciser as claimed in  claim 1 , wherein the positioning protrusions are integrally formed with the second handle. 
     
     
         4 . The grip exerciser as claimed in  claim 1 , wherein the positioning protrusions are hemispherical. 
     
     
         5 . The grip exerciser as claimed in  claim 1 , wherein each positioning protrusion has a smaller top portion and a larger lower portion, and the larger portion is capable of engaging with the free end of the spring. 
     
     
         6 . The grip exerciser as claimed in  claim 1 , wherein each positioning protrusion has a larger top portion and a smaller lower portion, and the larger portion is capable of engaging with the free end of the spring. 
     
     
         7 . The grip exerciser as claimed in  claim 1 , wherein each positioning protrusion is a tapered conical frustum, and a larger portion thereof is capable of engaging with the free end of the spring. 
     
     
         8 . The grip exerciser as claimed in  claim 1 , wherein each positioning protrusion is a conical frustum, and a larger portion thereof is capable of engaging with the free end of the spring. 
     
     
         9 . The grip exerciser as claimed in  claim 1 , wherein a padding member is located at an outer edge of each holding portion, and the padding member is softer than the holding portion. 
     
     
         10 . The grip exerciser as claimed in  claim 9 , wherein the padding member has a plurality of anti-slip patterns, and each anti-slip pattern is a groove. 
     
     
         11 . The grip exerciser as claimed in  claim 9 , wherein the padding member has a plurality of anti-slip patterns, and each anti-slip pattern is protruding. 
     
     
         12 . The grip exerciser as claimed in  claim 1 , wherein the second handle has corresponding indicating symbols adjacent to the positioning protrusions. 
     
     
         13 . The grip exerciser as claimed in  claim 1 , wherein the stopper of the connecting member is pivoted in the escaping space via the pivot.
