Abstract

A weightlifting barbell, having a barbell frame, a pair of three-axis rotatable and orbital handle mechanisms, and a pair of loadable weight sleeves. The handle mechanisms are mounted onto a horizontal section of the barbell frame, and the loadable weight sleeves are respectively mounted onto lower portions of a vertical section of the barbell frame. The handle mechanisms each contain three sets of bearing and shaft systems, allowing rotational movement in the X-axis, Y-axis, and Z-axis simultaneously, creating a free and orbital movement of handle grips of the handle mechanisms at any given time. The handle mechanisms are fixed along the barbell through a screw clamp mechanism. The handle grips are located higher in position relative to the loadable weight sleeves, to keep the barbell remaining plumb and upright during the rotational and orbital movement of the handle grips, while the barbell is free to pendulate during exercise.

Claims4

Dependent claims

A weightlifting barbell, comprising:

a U-shaped frame, including:
an elongated horizonal portion having two opposing ends and a cross-sectional shape, the cross-sectional shape being non-circular with a plurality of edges extending along a longitudinal axis of the elongated horizontal portion;
and
two vertical portions respectively extending downward from the two opposing ends;
a pair of loadable barbell weight sleeves respectively coupled to lower portions of the two vertical portions and respectively extending away from the U-shaped frame, the pair of loadable barbell weight sleeves being substantially parallel to the longitudinal axis;
two shoe footplates respectively coupled to lower ends of the two vertical portions, each shoe foot plate extending laterally away from opposing sides of the corresponding vertical portion and located adjacent to the corresponding loadable barbell weight sleeve, the two shoe footplates being substantially perpendicular to both the longitudinal axis and the two vertical portions, respectively, and configured to enable the weightlifting barbell to rest on a floor without falling over;
and
two handles coupled along the elongated horizonal portion, the two handles being rotatable in an X-axis, a Y-axis, and a Z-axis, each handle comprising:
a first bearing and shaft system to enable rotation in the X-axis;
a second bearing and shaft system to enable rotation in the Y-axis;
and
a third bearing and shaft system to enable rotation in the Z-axis.
