Exercise apparatus

Abstract

An exercise apparatus includes a base having a bracket member and a wheel pedal unit mounted at the base at a location far apart from the bracket member. A moving arm member is retractably coupled to the bracket member and movable relative to the bracket member in an angle of inclination between a first position and a second position. A seat unit is mounted at the moving arm member. Moving the moving arm member between a first location and a second location can change the elevation difference between the seat unit and the wheel pedal unit in both the vertical and horizontal directions, thus enabling the user to selectively perform different exercise modes in either a normal sitting posture or a recumbent sitting posture.

What is claimed is: 
     
         1 . An exercise apparatus, comprising:
 a base including a bracket member;   a wheel pedal unit installed on said base and configured to be spaced apart from said bracket member at a distance for pedaling by the legs of a user;   a moving arm member retractably mounted in said bracket member, said moving arm member comprising a movable part movable in and out of said bracket member in a predetermined angle of inclination between a first position located far apart from said bracket member and a second position located close to said bracket member; and   a seat unit mounted at said movable part of said moving arm member for sitting by the user, said seat unit being movable with said movable part between said first and second positions to change the elevation difference between said seat unit and said wheel pedal unit in both a horizontal direction and a vertical direction.

         6 . The exercise apparatus as claimed in  claim 5 , wherein the rail holder further comprises a first stop block and a second stop block respectively located at two opposite ends thereof, such that the first stop block is located adjacent to the bracket member and the second stop block is located farther away from the bracket member. 
     
     
         7 . The exercise apparatus as claimed in  claim 2 , further comprising a handle assembly pivotally connected to one of said wheel pedal unit and said upright support, and movable between a falling down position located adjacent to said seat unit and an upright position located far apart from said seat unit. 
     
     
         8 . The exercise apparatus as claimed in  claim 7 , wherein said handle assembly comprises a sleeve pivotally connected to said wheel pedal unit, and a handlebar coupled to said sleeve for holding by the hands of the user. 
     
     
         9 . The exercise apparatus as claimed in  claim 8 , wherein said handle assembly further comprises a movable bar having one end thereof coupled to said sleeve and an opposite end thereof terminating in said handlebar. 
     
     
         10 . The exercise apparatus as claimed in  claim 9 , wherein said movable bar is telescopically movable in and out of said sleeve. 
     
     
         11 . The exercise apparatus as claimed in  claim 9 , wherein said movable bar is arranged parallel to said moving arm member when said handle assembly is in said upright position. 
     
     
         12 . The exercise apparatus as claimed in  claim 8 , wherein said handlebar of said handle assembly comprises two grips spaced from each other at a distance larger than the width of said seat unit so that said grips are located at two opposite lateral sides relative to said seat unit when said handle assembly is in said falling down position. 
     
     
         13 . The exercise apparatus as claimed in  claim 1 , wherein when said seat unit is moved with said moving arm member to said first position, the elevation difference between said seat unit and said wheel pedal unit reaches the maximum point in the vertical direction and the minimum point in the horizontal direction; and when said seat unit is moved with said moving arm member to said second position, the elevation difference between said seat unit and said wheel pedal unit reaches the minimum point in the vertical direction and the maximum point in the horizontal direction. 
     
     
         14 . An exercise apparatus, comprising:
 a base including a bracket member and a rail holder coupled with said bracket member;   an upright support located at said rail holder and kept apart from said bracket member at a distance, wherein said upright support is movable along said rail holder;   a wheel pedal unit installed on said base and configured to be spaced apart from said bracket member at a distance for pedaling by the legs of a user;   a moving arm member retractably mounted in said bracket member, said moving arm member comprising a movable part movable in and out of said bracket member in a predetermined angle of inclination between a first position located far apart from said bracket member and a second position located close to said bracket member; and   a seat unit mounted at said movable part of said moving arm member for sitting by the user, said seat unit being movable with said movable part between said first and second positions to change the elevation difference between said seat unit and said wheel pedal unit in both a horizontal direction and a vertical direction.   
     
     
         15 . The exercise apparatus as claimed in  claim 14 , wherein said upright support is slidingly mounted to the rail holder, and said wheel pedal unit is mounted at said upright support. 
     
     
         16 . The exercise apparatus as claimed in  claim 14 , wherein the rail holder further comprises a first stop block and a second stop block respectively located at two opposite ends thereof, such that the first stop block is located adjacent to the bracket member and the second stop block is located farther away from the bracket member. 
     
     
         17 . The exercise apparatus as claimed in  claim 14 , wherein the moving arm member is telescopically movable in and out of the bracket member. 
     
     
         18 . An exercise apparatus, comprising:
