Portable exercising apparatus

Abstract

A portable exercising apparatus includes a holder block fixedly mounted inside a housing and defining a transverse track, a slide slidably mounted in the track of the holder block, two pull belts respectively fastened to one end of the track and the slide and extended out of two opposite lateral sides of the housing for pulling by the user to exercise the muscles of the arms, and a damping spring member mounted inside the housing for imparting a damping resistance to the slide upon movement of the slide by the user.

1 . A portable exercising apparatus comprising: 
 a housing;    a holder block fixedly mounted inside said housing, said holder block comprising a transversely extended track;    a slide coupled to and axially movable along said track of said holder block;    a first pull belt fixedly fastened to one end of said track of said holder block and extended out of a first lateral side of said housing;    a second pull belt fixedly fastened to said slide and extended out of a second lateral side of said housing; and    a damping spring member mounted in said holder block and coupled to said slide for imparting a damping resistance to said slide upon moving of said slide in said track.    
   
   
       2 . The portable exercising apparatus as claimed in  claim 1 , further comprising a first cross rod fixedly fastened to said holder block and extended across one end of said track for holding one end of said first pull belt, and a second cross rod fixedly mounted inside said slide for holding one end of said second pull belt.  
   
   
       3 . The portable exercising apparatus as claimed in claim  1 , wherein said housing comprises a transverse sliding slot transversely extended in a top wall thereof corresponding to said track, and graduations marked on the top wall along one side of said transverse sliding slot; said slide has a top index block inserted into said transverse sliding slot of said housing.  
   
   
       4 . The portable exercising apparatus as claimed in  claim 1 , wherein said holder block comprises a locating rod adapted to hold said damping spring member.  
   
   
       5 . The portable exercising apparatus as claimed in  claim 1 , further comprising a damping resistance adjustment member mounted in and movable along a sliding way in said holder block for adjusting the damping resistance produced by said damping spring member at said slide.  
   
   
       6 . The portable exercising apparatus as claimed in  claim 5 , wherein said housing comprises a longitudinal sliding slot longitudinally extended in a top wall thereof, and graduations marked on the top wall along one side of said longitudinal sliding slot; said damping resistance adjustment member has a top index portion inserted into said longitudinal sliding slot of said housing.  
   
   
       7 . A portable exercising apparatus comprising: 
 a housing;    a holder block fixedly mounted inside said housing. said holder block comprising a transversely extended track;    a slide coupled to and axially movable along said track of said holder block;    a first press grip inserted through a first lateral side of said housing and fixedly fastened to one end of said track of said holder block;    a second press grip inserted through a second lateral side of said housing and fixedly fastened to said slide; and    a damping spring member mounted in said holder block and coupled to said slide for imparting a damping resistance to said slide upon moving of said slide in said track.    
   
   
       8 . The portable exercising apparatus as claimed in  claim 7 , wherein said housing comprises a transverse sliding slot transversely extended in a top wall thereof corresponding to said track. and graduations marked on the top wall along one side of said transverse sliding slot: said slide has a top index block inserted into said transverse sliding slot of said housing.  
   
   
       9 . The portable exercising apparatus as claimed in  claim 7 , wherein said holder block comprises a locating rod adapted to hold said damping spring member.  
   
   
       10 . The portable exercising apparatus as claimed in  claim 7 . further comprising a damping resistance adjustment member mounted in and movable along a sliding way in said holder block for adjusting the damping resistance produced by said damping spring member at said slide.  
   
   
       11 . The portable exercising apparatus as claimed in  claim 10  wherein said housing comprises a longitudinal sliding slot longitudinally extended in a top wall thereof, and graduations marked on the top wall along one side of said longitudinal sliding slot: said damping resistance adjustment member has a top index portion inserted into said longitudinal sliding slot of said housing.
