Rere~ g to Figures 2 and 3, an abd(lmin~l cAelcisillg apparatus in S accordance with the present invention is generally co~ lised of a base frame 2, a substantially U-shaped frame 1 fastened to two opposite ends of the base frame 2, a back cushion 6 fiAedly secured to the base frame 2, and two elbow cll~hinn~ 3 mounted on two opposite ends of the U-shaped frame 1. The U-shaped frame 1 is colllp,i ,cd of a transverse tube 12, two parallel connecting tubes 11, and two elbow tubes 10 respectively connected to two opposite ends of the base tube 12 by the connecting tubes 11 to hold the elbow cushions 3. The connecting tubes 11 are respectively and detachably connected to the two opposite ends of the l,~ e~e tube 12 by detachable connecting means, such as plug joints or the like and then fi-Aed by a removable fixing means, such as a screw, bolt, pin or the like. The elbow tubes 10 are respectively turned about a respective pivot bolt 5 at one end of each connecting tube 11, and then fixed in the operative position by a removable fiAing means 4, such as a screw, bolt, pin or the like. Therefore, when the removable fixing means 4, such as a screw, bolt, pin or the like are removed from the connecting tubes, the elbow tubes 10 can be turned about the respective pivot bolts S from the operative position to the coll~psed position closely attached to the connecting tubes 11 to ",i~-i",i,e the storage S space.
In one embodiment of the invention, the eAelcise device or apparatus co~ es pivoting means, such as a pair ~pair of stands or feet which may be connected to the elbow tubes of the apparatus by means of a pin, bolt, pin-like devi~e, or similar device, such that the elbow tube of the exercise apparatus pivots freely on or about said pivoting means. In this embodiment of the invention, the apparatus moves in a fixed arc of a circle wherein said pin serves as the center of said circle. This embodiment may be described by rererellce to Figures 4, 5 and 6.
In this embodiment, the pivoting means 22 coll,plises a base 24 and support means 26 mounted on said base 24 and colllplising two opposing walls on said base 24. The support means 26 are distanced from each other sufflciently to receive and be pivotably connected to the elbow tube 10, such that elbow tube 10 may pivot freely between the two opposing walls of support means 26. Each opposing wall on said base 24 con~ains an opening 28 for receiving the pin 30, the respective openings being on a common h~.,;,.o"lal axis relative to the base. Each of the two pivoting means 22 is connected to one elbow tube 10 of the apparatus by means of a pin or pin-like S device 30 which extends holi~ontally through an opening 28 in one opposing wall 26 of the pivoting means, through the diameter of the elbow tube, and through an opening 28 in the other opposing wall of the support means 26 of the pivoting means 22.

In particular, the base frame 2 may be connected to the upper ends of the connecting tubes 11, with the elbow tubes 10 connected to the lower end of said connecting tubes. A back cushion 6 for supporting the neck and/or head may be affixed to the base frame. In such a configuration, the opposing ends of the U-shaped tube 1 may be connected to the connecting tubes 11 between said base frame and said elbow tubes. In such a configuration, the elbow cushions 3 are placed on or around the U-shaped tube near the opposing ends of said U-shaped tube.
The under side of the base 24 of the pivoting means may complise a friction enhancing surface to decrease the degree of undesirable motion of the appalalus when in use, such as shifting or sliding. Said surface may colll~lise a separate textured material applied to the base or it may coll,plise a feature of the structure of the base, or a combination thereof.
By whatever means formed, the pin 30 co~ lises a shaft 32 of lesser diameter collllllunicating between two ends 34 of larger diameter. Said ends 34 are of sufflciently larger diameter than the openings 28 such that the pin 30, after insertion, cannot be readily dislodged from the opposing walls 26 of the pivoting means 22 by the normal motion of the apparatus in use.
This app1ic~tir~n is a con~ ualion-in-part of pending U.S. application Serial No. 08/501,614, filed July 12, 1995.
