First Claim
Patent Images
1. An adjustable-weight exercise apparatus comprising:
- a rod with opposing end sections each having a transverse cross section defining first, second, and third longitudinally-extending surfaces positioned circumferentially, and a detent between the second and third longitudinally-extending surfaces; and
a plurality of weights each having a hub defining a hole shaped to slide onto one of the opposing end sections;
the hub including a bearing surface for slidably engaging the first longitudinally-extending surface and including at least one flexible finger with a tip extending radially inward within the hole, the flexible finger configured to slide along the second longitudinally-extending surface when in a first rotational orientation during assembly of the weights onto one of the end sections of the rod, and configured to flex over the detent and then interlockingly engage the third longitudinally-extending surface when the weight is rotated to thus lock the weights onto the rod; and
wherein the at least one finger includes opposing fingers extending in opposite directions, and wherein the first, second and third longitudinally-extending surfaces of the rod include first, second and third opposing surfaces.

Abstract
An adjustable-weight exercise apparatus include a rod with opposing end sections defining bearing surfaces, a first shallow channel without ribs, and a second shallow channel with ribs. The weights each include a hub shaped to telescopingly slide onto ends of the rod. Each hub further includes opposing flexible fingers with tips configured to slide along the second shallow channel when in a first rotational orientation during assembly of the weights onto the rod, and configured to flex over a raised detent into engagement with the second shallow channel between the ribs when the weight is rotated.
