ADJUSTABLE-WEIGHT EXERCISE APPARATUS AND METHOD
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 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.

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.

20. An apparatus comprising:
-
a rod with a first surface defining a cylinder, a second surface defining an assembly-permitting shallow channel, and a third surface defining a weight-locking shallow channel with longitudinally spaced ridges; and a plurality of weights each having a hub defining a hole shaped to slide onto ends of the rod;
at least two of the weights including a bearing surface in their hub for slidably engaging the first surface and including at least one flexible finger configured to slide along the second surface when in a first rotational orientation during assembly of the weights onto the rod, and configured to flex over the detent and then interlockingly engage the third surface when the weight is rotated.

21. An adjustable exercise apparatus comprising:
-
a rod with ends each having a transverse cross section defining at least a first recessed surface and a detent adjacent the recessed surface; and a plurality of weights each designed to telescopingly slide onto one of the ends;
the weights each including a hub with a bearing surface for slidably engaging one of the ends and including at least one flexible finger configured to permit sliding assembly onto the ends when in a first rotational orientation, and configured to flex over the detent and then interlockingly engage the recessed surface when the weight is rotated.

22. An adjustable exercise apparatus comprising:
-
a rod; and a plurality of weights each configured to slide onto the rod when in a first rotational orientation and configured to interlockingly engage the rod when rotated to a second rotational orientation. - View Dependent Claims (23, 24)

25. A method of exercising comprising steps of:
-
providing a rod and weights configured for self-attachment to the rod; assembling at least one weight onto each end of the rod; and securing the weights to the ends by rotating the weights on the rod from a first rotational orientation to an interlocking second rotational orientation.
