ADJUSTABLE GYMNASTIC BAR SUPPORTED BY A-FRAMES
First Claim
1. In a gymnastic device, a pair of oppositely disposed A-frames each comprised of a pair of diagonally disposed legs, means for detachably connecting the upper ends of each pair of legs, the lower ends of each of said legs having means thereon for frictionally engaging a supporting surface, and a horizontal cross brace interconnecting said legs on each of said A-frames;
- at least one horizontally disposed gymnastic bar extending from one of said legs of one of said A-frames to a corresponding leg of the other of said A-frames, said gymnastic bar being spaced above said lower ends of said legs;
bracket means for independently adjustably securing said at least one bar to said two respective legs;
said at least one bar comprising the sole means of connection between said Aframes; and
an outwardly extending guy wire being attached to each of said A-frames and being adapted to be secured to support means outwardly from said A-frAme.

Abstract
A device including oppositely disposed upstanding A-frames having corresponding legs on one side side at least interconnected by a gymnastic bar. The connection between the bar and the legs is by a mounting bracket having a first sleeve slidably and adjustably movable on the leg and a second sleeve vertically oriented for receiving a downwardly extending pin on the gymnastic bar. The two A-frames and mounting brackets may be appropriately used with different types of gymnastic devices.

said bar having downwardly extending end pins received in said second sleeves;
set screw means on said first and second sleeves for providing selective adjustable attachment of said first and second sleeves on said legs and said end pins respectively.
- a horizontally disposed gymnastic bar extending from one leg of one A-frame to a corresponding leg of the other A-frame; and
-
4. The structure of claim 3 wherein said pair of diagonally disposed legs are pivotally interconnected at their upper ends.
-
5. The structure of claim 3 wherein a second bracket means as said first bracket means is defined is slidably mounted on one of said parts to support one end of a second gymnastic device.
-
