Abstract
In an exercise apparatus for exercising having a horizontal bar and a plurality of weights, the weights including a bar receiving slot opening through the lower edge of the weight, and a closed end intermediate the height of the weight and above the center of gravity of the weight when the bar is at the closed end of the slot, the weight being gravity biased to a position where the open end of the slot is below the bar.
Claims13
In an exercise apparatus including a horizontal bar and weights mounted on said bar, the improvement comprising a plurality of weights each having a flat base surface and each having a bar receiving slot opening through said flat base surface and defined by parallel opposed walls, said walls being perpendicular to said flat base surface and to a broad side surface of said weight, said slot having a closed end intermediate the height of said weight and sufficiently above the center of gravity of said weight that when said bar is at the closed end of said slot the bar is above the center of gravity of said weight, whereby said weight is gravity biased to a position at which said open end of said slot is below said bar, said exercise apparatus including unslotted fixed weights at either end of said horizontal bar and means for securing said fixed weights to said bar.
In an exercise apparatus including a horizontal bar and weights mounted on said bar, the improvement comprising:
- a plurality of weights each having a bar receiving slot opening through a lower edge of said weight and a closed end intermediate the height of said weight and sufficiently above the center of gravity of said weight that when said bar is at the closed end of said slot the bar is above the center of gravity of said weight, whereby said weight is gravity biased to a position at which said open end of said slot is below said bar;
- and
- means for preventing lateral movement of said weights on said bar including grooves in walls defining said slot and an annular rib concentric about said bar, said annular rib extending into said grooves.
In an exercise apparatus including a horizontal bar and weights mounted on said bar, the improvement comprising:
- a plurality of weights each having a bar receiving slot opening to a lower edge of said weight and a closed end intermediate the height of said weight and sufficiently above the center of gravity of said weight that when said bar is at the closed end of said slot the bar is above the center of gravity of said weight, whereby said weight is gravity biased to a position at which said opened end of said slot is below said bar;
- and
- a tether attached to said weight adjacent to the open ended of said slot and ground to a floor, said tether maintaining downward orientation of said slot.
In an exercise apparatus including a horizontal bar and weights mounted as said bar, the improvement comprising:
- a plurality of weights, each having a bar receiving slot open to a lower edge of said weight and a closed end intermediate the height of said weight and sufficiently above the center of gravity of said weight that when said bar is at the closed end of said slot the bar is above the center of gravity of said weight, whereby said weight is gravity biased to a position at which said open end of said slot is below said bar;
- unslotted fixed weights at either end of said horizontal bar and means for securing said fixed weights to said bar, said fixed weights preventing said weights from moving laterally to the outer ends of said bar;
- and
- magnet means attached to said weights, said magnets securing said fixed end weights to said weights.
