A chin up bar assembly is provided with a cross bar and a pair of handles slidably mounted on the cross bar. The handles are pivotally mounted for movement between locked and unlocked positions. When a user hangs from the handles, the handles automatically pivot to the locked position to frictionally engage the cross bar and prevent sliding movement of the handles along the cross bar. The handles also can be swiveled during use to exercise different muscles in the user's arms, chest and back.

What is claimed is: 1. A chin up bar assembly, comprising: a cross bar; a pair of collars slidably mounted on the cross bar; a pair of handles pivotally mounted on the collars; the handles being held in a selected position substantially at any point along the cross bar by application of a portion of a user's weight to the handles. 2. The assembly of claim 1 wherein the handles are pivotal between locked and unlocked positions. 3. The assembly of claim 1 wherein the handles are movable relative to the collars between an unlocked position for sliding along the cross bar, and a locked position for preventing sliding along the cross bar. 4. The assembly of claim 1 wherein the handles are pivotal relative to the collars about horizontal and vertical shafts. 5. The assembly of claim 1 wherein each handle includes an arm having opposite first and second ends and the arm being pivotally mounted to one of the collars at a point between the opposite ends for rotation about an axis parallel to the cross bar. 6. The assembly of claim 5 wherein each handle includes a handgrip mounted to the first end of the arm whereby the user's weight will pivot the second end of the arm into frictional engagement with the cross bar so as to lock the handle against sliding movement. 7. The assembly of claim 5 wherein the first end of each arm includes a tube and each handle includes a handgrip with a shaft pivotally received in the tube, whereby the handgrip is pivotal while the handle is fixed against sliding movement along the bar. 8. The assembly of claim 1 wherein the handles include handgrips spaced forwardly from the cross bar. 9. The assembly of claim 8 wherein the handles each includes an arm pivotally mounted to the cross bar about a horizontal shaft to define a fulcrum. 10. The assembly of claim 1 wherein the handles engage a bottom surface of the cross bar to lock the handles in position and preclude sliding movement of the handles along the cross bar. 11. A method of setting a pair of chin up handles at a selected position along a cross bar, comprising: sliding each handle to a selected position along the bar; pivoting each handle to a locked position such that a user's weight alone precludes sliding of the handles along the cross bar, wherein each handle includes a collar slidably mounted to the cross bar. 12. The method of claim 11 wherein movement to the locked position is achieved by gripping a handgrip of each handle such that the weight of the user pivots a portion of the handle into frictional engagement with the cross bar. 13. The method of claim 11 further comprising swiveling the handles about a substantially vertical axis to a desired orientation. 14. The method of claim 11 further comprising moving each handle to an unlocked position wherein the handle is disengaged from the cross bar to allow sliding movement of the handle along the cross bar. 15. The method of claim 11 further comprising engaging a bottom surface of the cross bar with the handles to retain the handles in a locked position. 16. The method of claim 11 wherein each handle includes a handgrip, the method further comprising positioning the hand grips forwardly firm the cross bar. 17. A chin up bar assembly, comprising: a cross bar; a pair of collars slidably mounted on the cross bar; and a handle on each collar and pivotal relative to the collar about a substantially vertical shaft and a substantially horizontal shaft. 18. The assembly of claim 17 wherein the handles are pivotally mounted on the cross bars for movement between locked and unlocked positions. 19. The assembly of claim 18 wherein the handles are held in the locked position solely by the user's weight. 20. The assembly of claim 18 wherein the handles each include a collar slidably mounted on the cross bar, and an arm pivotally mounted to the collar, the arm having a first end supporting the handgrip and a second end engageable with the cross bar when the handle is in the locked position. 21. The assembly of claim 17 wherein the handles include handgrips spaced forwardly from the cross bar. 22. The assembly of claim 17 wherein the handles engage a bottom surface of the cross bar to lock the handles in position and preclude sliding movement of the handles along the cross bar.
