Total body exercise equipment

Abstract

This invention relates to total body exercise equipment. The exercise equipment includes a first crankshaft to which first crank arms having grips and a first sprocket are installed and a second crankshaft to which second crank arms having pedals, a second sprocket and a third sprocket are installed. A driven shaft includes a wheel and a driven sprocket installed thereto. A first driving force transmitting means is engaged with the first sprocket and the second sprocket that the first crankshaft and the second crankshaft are linked. A second driving force transmitting means is engaged with the third sprocket and the driven sprocket that torque of the third crankshaft is transmitted to the driven shaft. The first and the second crankshafts are installed to a frame. The driven shaft is installed to bracket and the frame and the bracket are fixed to a base.

1 . A total body exercise equipment comprising:
 a first crankshaft to which first crank arms having grips and a first sprocket are installed; a second crankshaft to which second crank arms having pedals, a second sprocket and a third sprocket are installed;   a driven shaft to which a wheel and a driven sprocket are installed;   a first driving force transmitting means so engaged with the first sprocket and the second sprocket that the torques of the first crankshaft and the second crankshaft are transmitted each other thereby the first crankshaft and the second crankshaft are linked;   a second driving force transmitting means so engaged with the third sprocket and the driven sprocket that the torque of the third crankshaft is transmitted to the driven shaft thereby the driven shaft rotates;   a frame to which the first and the second crankshafts are installed;   a bracket on which the driven shaft is installed; and   a base on which the frame and the bracket are fixed.   
     
     
         2 . The total body exercise equipment according to  claim 1  wherein:
 gears are formed on the outer circumferences of the first sprocket, the second sprocket, the third sprocket and the driven sprocket, and the first driving force transmitting means and the second driving force transmitting means are timing belts. 
 
     
     
         3 . The total body exercise equipment according to  claim 1  wherein:
 gears are formed on the outer circumferences of the first sprocket, the second sprocket, the third sprocket and the driven sprocket, and the first driving force transmitting means and the second driving force transmitting means are chain belts. 
 
     
     
         4 . The total body exercise equipment according to  claim 2  wherein:
 idler guides are so installed to be engaged with inner circumference and outer circumference of the first driving force transmitting means to control the orbit and the tension of the first driving force transmitting means to control the tension. 
 
     
     
         5 . The total body exercise equipment according to  claim 1  wherein:
 the frame further comprises a saddle attachment part on which a saddle is attached. 
 
     
     
         6 . The total body exercise equipment according to  claim 1  wherein:
 the frame further comprises a fixed grip. 
 
     
     
         7 . The total body exercise equipment according to  claim 1  wherein:
 the total body exercise equipment further comprises a load applying means for applying load to the wheel and a load control means for controlling the load. 
 
     
     
         8 . The total body exercise equipment according to  claim 7  wherein:
 the material of the wheel is metal, and the load applying means is a magnetism generating means which applies magnetism to the wheel. 
 
     
     
         9 . The total body exercise equipment according to  claim 7  wherein:
 the load applying means is a pad which applies friction force to the wheel. 
 
     
     
         10 . The total body exercise equipment according to  claim 8  wherein:
 the load control means comprises a wire which moves the magnetism generating means toward the wheel and a spring which exerts tensile force to retreat the magnetism generating means from the wheel. 
 
     
     
         11 . The total body exercise equipment according to  claim 8  wherein:
 the load control means comprises a wire which moves the magnetism generating means away from the wheel and a spring which exerts compression force to push the magnetism generating means toward the wheel. 
 
     
     
         12 . The total body exercise equipment according to  claim 9  wherein:
 the load control means comprises a wire which pulls the pad to be contact closely with the wheel and a spring which exerts tensile force to retreat the pad back from the wheel.
