Body twist exercising apparatus with adjustable resistance

Abstract

A body twist exercising apparatus having a variable resistance is developed, wherein the body twist exercising apparatus activates a mechanical switch to generate a resistance in one rotational direction and allowing a resistance-free rotation in a backward direction. The body twist exercising apparatus further comprises a mechanically controlled switch to adjust the resistance against rotational motions.

What is claimed is: 
     
         1 . A body twist exercising apparatus, comprising:
 a base with a flat surface;   a rotatory part, comprising:
 a stationary wheel having a first surface area, 
 an elliptical rotatory wheel having a second surface area which is smaller than the first surface area, and the elliptical rotatory wheel being attached parallel and concentric to the stationary wheel such that an overlapping section and a non-overlapping section form, and a gap between the parallel wheels formed; 
   a bobbin located in the non-overlapping section of the stationary wheel; and   a rubber pad secured in place with the bobbin,   wherein the rotatory part is mounted on the base, and wherein the rubber pad freely rotates, and the elliptical rotatory wheel is configured to rotate in clockwise and counter-clockwise directions.   
     
     
         2 . The apparatus of  claim 1 , further comprising a guardrail which is secured on the base. 
     
     
         3 . The apparatus of  claim 1 , wherein the apparatus creates a rotational resistance only in clockwise direction. 
     
     
         4 . The apparatus of  claim 1 , wherein the apparatus creates a rotational resistance only in counter-clockwise direction. 
     
     
         5 . The apparatus of  claim 1 , wherein the apparatus creates a rotational resistance in clockwise and counter-clockwise directions. 
     
     
         6 . The apparatus of  claim 2 , further comprising a handgrip which is mounted on the guardrail. 
     
     
         7 . The apparatus of  claim 2 , further comprising:
 a switch which is mounted on the guardrail; and   a pulley which is connected to the bobbin via a cord from a first end while concurrently connected to the switch via the cord from a second end.   
     
     
         8 . The apparatus of  claim 7 , wherein a rotational resistance of the elliptical rotatory wheel is controlled by the switch. 
     
     
         9 . The apparatus of  claim 7 , wherein a rotational resistance of the elliptical rotatory wheel is controlled by the switch only in clockwise direction. 
     
     
         10 . The apparatus of  claim 7 , wherein a rotational resistance of the elliptical rotatory wheel is controlled by the switch only in counter-clockwise direction. 
     
     
         11 . The apparatus of  claim 7 , wherein a rotational resistance of the elliptical rotatory wheel is controlled by the switch in clockwise and counter-clockwise directions.
