ABSTRACT:
An adjustable exercise bar comprises a bar (145) and one or more rails (100, 105) upon which one or more bar retainers are constrained to move. The rails are secured to a vertical surface such as a wall or post (110). A plunger assembly (400) contained within the bar retainers is coupled to the bar by a stiff metal band that is attached to the bar. A plunger in each plunger assembly is normally inserted in a hole (115) in the rail or rails, preventing the bar retainer from moving. The plunger assembly is actuated by rotating the front of the bar upward (from the user's perspective). This actuation causes the plunger (405) to be removed from the hole, enabling movement of the bar upward or downward. When the rotational force on the bar is removed, a spring (435) within the plunger assembly returns the bar to its original rotational position and returns the plunger to a hole in the rail. An optional weight (155) secured to the bar retainers by cords (160, 161) acts as a counterbalance to bar movement. An additional static bar (170) is provided to permit the performance of additional exercises.
