Abstract:
1. An adjustable, horizontal bar exercise apparatus, comprising: a bar, first and second vertically-oriented, parallel foraminous rails, each of said rails containing a plurality of vertically disposed holes wherein at least one hole in said first rail is located at a common vertical position with at least one hole in said second rail, a pair of bar retainers, each slidably mounted on one of said rails and each having a bore through which said bar extends and within which said bar can be urged to rotate, said bar retainers further each including a springably actuated plunger assembly comprising a spring and a plunger within a housing and a lever that connects said bar to said plunger, said plungers being arranged to arrest motion of said retainers when said bar is in a first rotational position, said plungers being arranged to arrest said motion when said bar is in said first rotational position within said retainers by causing said plungers to extend from said housing and from said retainers into respective vertically disposed holes in said rails so that said plungers extend into said respective holes to lock said retainers and said bar on said rails to prevent said retainers and said bar from moving up or down on said rails, and said lever being arranged so that when said bar is urged to rotate to a second rotational position, said lever also rotates and urges said plunger to withdraw from said vertically disposed holes in said rails, thereby permitting said retainers to move on said rails, whereby when said bar is in said first rotational position it is fixed at a first vertical position, and when said bar is in said second rotational position, it is free to move to a new vertical position.
