Portable exercise apparatus

Abstract

A portable exercise apparatus is provided. The portable exercise apparatus may include a base frame adapted to telescopically receive an extension frame. The extension frame may include four vertical extensions pivotably connected to four extension bars so as to form a generally simple cubic lattice shape. The four vertical extensions may include a plurality of spaced apart pin openings. The base frame may include four tubular vertical members. Each vertical member may include an upper end defining a opening for telescopically receiving the vertical extension. Near the upper end on each vertical member may include a locator pin sized for connecting with the pin openings. A user may telescopically mount the vertical extensions into the upper ends of the base frame by connecting four locator pins in predetermined pin openings along the length of the vertical extensions. The user may then perform body-weight exercises on at least one extensions bar at a predetermined height.

What is claimed is: 
     
         1 . A portable exercise apparatus comprising:
 a base frame comprising:
 four vertical members, wherein each vertical member terminates in an upper end and an opposing lower end, wherein each upper end defines an extension opening; and 
 four horizontal members, wherein each vertical member has an adjustable locator pin near each upper; and 
   an extension frame comprising:
 four vertical extensions, wherein each vertical extension terminates in a top end and an opposing bottom end; and 
 four extension bars, 
 wherein each vertical extension forms a plurality of spaced apart pin openings along the length thereof for receiving the locator pin. 
   
     
     
         2 . The portable exercise apparatus of  claim 1 , wherein the four vertical members are tubular, and wherein each bottom end is sized to be telescopically received by the extension openings. 
     
     
         3 . The portable exercise apparatus of  claim 3 , further including two horizontal braces, wherein each horizontal brace connects a pair of vertical members near their respective upper ends, and wherein each horizontal brace forms a plurality of apertures. 
     
     
         4 . A method of exercising on a portable exercise apparatus comprising:
 providing a portable exercise apparatus comprising: a base frame comprising: four tubular vertical members terminating in an upper end and an opposite lower end, wherein the upper ends each define an extension opening; and four horizontal members pivotably connected to the four respective vertical members so that the base frame folds from an operable position to a collapsed position, wherein the four vertical members have an adjustable locator pin near each upper end opposite the horizontal members; and an extension frame comprising: four vertical extensions, wherein the vertical extensions are sized to be telescopically received by the extension openings; and four extension bars, wherein the four extension bars are pivotably connected to the four vertical bars so that the extension frame folds from an operable position to a collapsible position, wherein the four vertical extensions form a plurality of spaced apart pin openings along the length thereof for rigidly receiving the locator pins;   performing body-weight exercises on at least on extension bars;   disconnecting the four locator pins from the four pin openings;   dismounting the extension frame from the base frame; and   transporting the extension frame and the base frame.   
     
     
         5 . The method of  claim 5 , further including providing at least one elastic band for performing body-weight exercises. 
     
     
         6 . The method of  claim 5 , further including providing at least one elastic tube for performing body-weight exercises. 
     
     
         7 . The method of  claim 6 , further including tying the extension frame and the base frame are tied together with the elastic band.
