Cyclonic rotor

Abstract

A cyclonic rotor is a arm muscle trainer, comprising a semicircular shield and a rolling ball, where the round shield is composed of an outer shield and inner shield. These two shields are superposed and expanded conically downward with a larger space at the bottom to contain a rolling ball. In the interior of the semicircular shields, there are two lock ears to be inserted into the T-type channel on the handle. The lock ears and the handle are fastened firmly together by two outer screws which come from the exterior of the semicircular shields. While holding the handle, waving the rotor, the ball rolls within the hollow space. If waving slowly, the ball rolls slowly; if waving fiercely, the ball rolls fast and violently and continues self-rolling with centrifugal and inertia force and effects vigorous training on arm muscle.

1 . A cyclonic rotor comprising a semicircular shield, a handle and a rolling ball characterized by that: 
 said semicircular shield constitutes said outer semicircular shield and said inner semicircular shield superposed to form a hollow space with a small diameter at a top and a large diameter at a bottom to contain said rolling ball, interior of said inner semicircular shield provides two lock ears to be inserted into a T type channel of said handle, said rolling bolt is employed to fasten said lock ear and handle firmly together; and    while holding said handle and waving said semicircular shield, said rolling ball rolls in said hollow space, if waving slowly, said rolling ball rolls slowly; if waving fiercely, said rolling ball rolls violently with fast and centrifugal movement.    
     
     
         2 . The cyclonic rotor of  claim 1 , wherein said outer and inner semicircular shields have a flat facet for aligning and locking them together.  
     
     
         3 . The cyclonic rotor of  claim 1 , wherein said outer semicircular shield provides a plurality of slots and indentations on its rim, said inner semicircular shield has a plurality of lock ears on its rim, when said outer and inner semicircular shields are superposed, and said outer semicircular shield is turned counter-clockwise, said lock ears of said inner semicircular shield will fit into said slots and indentations of said outer semicircular shield.  
     
     
         4 . A cyclonic rotor comprising a semicircular shield, a handle and a rolling ball characterized by that said semicircular shield is an integral formed extrusion with a hollow space formed within, two protruded bars are formed and disposed in opposite positions, an opening is provided nearby a bar having a diameter larger than said rolling ball to permit entrance of said rolling ball into said hollow space, a similar semicircular shield matching an inner rim of said semicircular shield is fixed on an interior part of said handle, said similar semicircular shield has two slots on an outer wall to receive said protruded bars on the other semicircular shield, then said semicircular shield and said handle shield are superposed and locked together by a bolt and a nut to come up with another cyclonic rotor.
