Portable exerciser

Abstract

An exerciser has a stand, a base and two covers. The stand has a supporting rod, a knob and a stand rod. The knob is detachably attached to the supporting rod. The stand rod is universally connected between the supporting rod and the knob. The base is detachably attached to the bottom of the stand to support the stand. The covers are pivotally connected to supporting rod of the stand. Each cover has a chamber to receive the elements of the stand and the base after the stand and the base are disassembled. Accordingly, the exerciser is detachable and portable so that the portable exerciser can be carried to anywhere conveniently.

What is claimed is:

 a stand with a bottom and constructed of by multiple elements, the stand comprising: 
 a supporting rod;  
 a knob detachably attached to the supporting rod; and  
 a stand rod universally connected between the supporting rod and the knob, the stand rod having a rod body with a top and a bottom and a ball with a top portion and a bottom portion formed on the top of the rod body and universally connected between the supporting rod and the knob;  
   a base constructed of at least one element and detachably attached to the bottom of the stand to support the stand; and    two covers pivotally connected to supporting rod of the stand, each respective cover having a top and a bottom with a chamber, and the chamber in each cover having multiple baffles for selectively holding the elements of the stand and the base after the stand and the base are disassembled.    
     
     
         2 . The exerciser as claimed in  claim 1 , wherein the supporting rod has a middle portion and a threaded hole defined in the middle portion of the supporting rod; 
 a through hole with a diameter smaller than that of the threaded hole is defined in a bottom of the threaded hole to form a shoulder between the threaded hole and the through hole;    the rod body of the stand rod penetrates through the through hole in the supporting rod;    the bottom portion of the ball on the stand body is supported on the shoulder in the supporting rod;    the knob has a stub extending downward from the knob and an outer thread formed on the stub to screw with the threaded hole in the supporting rod; and    the stub has a bottom and a curve cavity defined in the bottom of the stub to receive the top portion of the ball.    
     
     
         3 . The exerciser as claimed in  claim 2 , wherein the rod stand further has a neck with a diameter smaller than that of the rod body and formed between the ball and the rod body.  
     
     
         4 . The exerciser as claimed in  claim 2  further comprising a positioning plate with a bottom and a through hole mounted around the stub on the knob and abutting with the knob, 
 wherein the positioning plate has two curve edges formed on opposite sides of the positioning plate and two flat edges formed on another opposite sides of the positioning plate; and  
 each respective cover has a recess with a bottom and a curved inner edge defined in one side of the top of the respective cover to selectively receive one of the curve edges on the positioning plate.  
 
     
     
         5 . The exerciser as claimed in  claim 4 , wherein the positioning plate has a bottom and two protrusions formed on the bottom of the positioning plate; and 
 each respective cover has a depression defined in the bottom of recess to selectively receive one of the protrusions on the positioning plate.    
     
     
         6 . The exerciser as claimed in  claim 2 , wherein the supporting rod has two grooves respectively defined around two ends of the supporting rod; and 
 each respective cover has a holding tab with a curve recess to selectively engage with one of the grooves in the supporting rod.    
     
     
         7 . The exerciser as claimed in  claim 2 , wherein the stand rod has multiple longitudinal channels defined in an outer periphery of the rod body along an axial direction of the rod body; and 
 the base has multiple legs each having a rail detachably attached to one of the channels in the stand rod.    
     
     
         8 . The exerciser as claimed in  claim 7 , wherein each respective channel in the stand rod extends to the bottom of the rod body.  
     
     
         9 . The exerciser as claimed in  claim 7 , wherein each respective leg of the base has a top and an inverse U-shaped recess defined in the top of the leg; and 
 a supporting bar with a U-shaped cross section is pivotally attached to each respective leg and covers the inverse U-shaped recess in the leg.    
     
     
         10 . The exerciser as claimed in  claim 9 , wherein each respective leg has two pivotal holes respectively defined in two sides of the leg; and 
 each respective supporting bar has two pivots respectively inserted into the pivotal holes in the corresponding one of the legs.    
     
     
         11 . The exerciser as claimed in  claim 7 , wherein the supporting rod has multiple cavities; and 
 the supporting bars on the legs of the base are selectively engaged with the cavities on the supporting rod when the supporting bars are pivotally rotated relative the legs.    
     
     
         12 . The exerciser as claimed in  claim 1 , wherein each respective cover has a skirt extending around the bottom of the cover so as to define a chamber in the bottom of the cover.  
     
     
         13 . The exerciser as claimed in  claim 1 , wherein each cover has multiple bumps formed on the top of the cover.  
     
     
         14 . The exerciser as claimed in  claim 1  further comprising two U-shaped rod holders respectively enclosing two sides of the supporting rod and detachably attached to the covers.  
     
     
         15 . The exerciser as claimed in  claim 14 , wherein each respective cover has two lock holes; and
