Problems solved by technology

[0005] One problem associated with prior art barbells is that if the bar is to withstand bending forces when lifted with the weights at the ends, it must be made of a strong and relatively heavy material
Another problem is that the use of disc-shaped end weights creates storage and transport problems for the barbell with associated weights
[0006] Another problem associated with conventional barbells with or without rotatable grips is that it is inconvenient and unsuitable to provide a heavier weight at one end than the other, resulting in asymmetrical stress on the user's muscles during exercise

Embodiment Construction

[0027] refer to Figure 1-4 A preferred embodiment of the exercise apparatus of the present invention includes a pair of outer rings 10 and 12, which are preferably made of tubular steel, aluminum or other rigid material. The rings 10 each have a plurality of threaded holes 14 made at equal intervals around their circumference for securing the rotatable inner ring in a manner to be described subsequently.

[0028] The two outer rings 10 and 12 are connected to each other by a pair of curved tubular connecting rods 16 and 18 . The ends of the rods are welded or otherwise fixed to spaced points around the periphery of the outer rings 10 and 12 . The rods and other elements of the exercise machine can be made of alloy or composite materials and be solid or tubular. A straight central rod 20 , preferably rectangular in cross-section, extends between the two curved connecting rods 16 and 18 and its ends are also fixed to the peripheries of the two rings 10 and 12 and midway betwe...

Abstract

An exercise barbell comprises a pair of rings connected by a pair of curved bars. The rings rotatably support handle members. Extensions of the bar on the exterior of the two rings support crescent-shaped weights which conform to the outer diameter of the ring and to one another. The weights are relatively flat so the entire apparatus lies in a single plane. A straight bar connecting the opposed sides of the two rings supports a sliding weight which may be moved to one side of the bar or the other to allow asymmetrical exercises.

Description

[0001] related application [0002] This application claims priority to U.S. Provisional Patent Application Serial No. 60 / 547,590, filed February 25, 2004, and U.S. Provisional Patent Application Serial No. 60 / 564,671, filed April 21, 2004 , the above provisional application is hereby incorporated by reference. technical field [0003] The present invention relates to barbells for exercise purposes, such as weightlifting, and more particularly to exercise machines that include means for supporting a plurality of weights at both ends of the machine and include rotatable handles supported on a central rod sliding weights, and rectangular curved weights that can be supported at the end of the instrument. Background technique [0004] Barbells are commonly used for various exercises including curling and weightlifting, and it has been proposed to provide a rotating grip for use in such equipment so that the user's grip can be adapted to any position without Confined to angles ...
