Abstract
A doorway mounted chin-up bar has a rod with an interior tube that is telescopically received within a rotating sleeve. A mount is positioned on each end of the rod for securing the rod to a doorjamb. A pair of U-shaped extension bars extend outward and upward from the rod. Each of the extension bars have first and second ends that extend out of planes that are defined by the doorway in first and second directions, respectively. A first hand-grip bar is affixed to the first ends of the extension bars and a second hand-grip bar is affixed to the second ends of the extension bars. When a user grasps the first hand-grip bar and pulls down, the extension bars pivot about the rod until the second hand-grip bar engages a wall surface above the doorway. The user may engage in chin-ups while being supported by the first hand-grip bar. Alternatively, a user may grasp the second hand-grip bar and pull down until the first hand-grip bar engages a wall surface above the doorway. The second hand-grip bar supports the user while the user engages in chin-ups. The first and second hand-grip bars are different distances away from the rod such that the hand-grip bars will be at different heights above the floor.
