FIG. 2.

EXERCISE BAR BACKGROUND OF THE INVENTION FIELD OF THE INVENTION The present invention relates to an exercise bar of the type including interchangeable weights.

SUMMARY OF THE INVENTION The exercise bar of the instant invention includes an elongate bar having a pair of depending shafts rigidly secured thereto in spaced parallel relation adjacent the opposite ends of the exercise bar. The shafts are threaded to receive weights which are secured to the shafts by washers and nuts. Clearly rotatable hand grips are positioned on the bar adjacent opposite ends thereof to permit the bar to be used with the weights being swung in a complete circle while performing various exercises such as overhead lift from the floor, forward curl. reverse curl. kneebends, shoulder press and the like.

The primary object of the invention is to provide an exercise bar having interchangeable weights which can be swung around the bar while performing exercises with the bar.

Other objects and advantages will become apparent in the following specification when considered in light of the attached drawings.

BRIEF DESCRIPTION OF THE DRAWINGS FIG, 1 is a top plan view of the invention;

FIG. 2 is a front elevation of the invention;

FIG. 3 is an enlarged vertical sectional view, taken along the line 33 of FIG. 2, looking in the direction of the arrows; and

FIG. 4 is an enlarged fragmentary sectional view, taken along the 44 of FIG, I, looking in the direction of the arrows.

DESCRIPTION OF THE PREFERRED EMBODIMENT Referring now to the drawings in detail, wherein like reference characters indicate like parts throughout the several figures. the reference numeral IO indicates generally an exercise bar constructed in accordance with the invention,

The exercise bar includes an elongate generally cylindrical member 1 I provided with a pair ofgenerally cylindrical freely rotatable hand grips I2 adjacent the opposite ends of the member ll. At each end of each of the hand grips 12 the member I1 is provided with a circumferential groove 13 in which is sitted a spring retaining split ring 14 to maintain the cylindrical handle 12 in its correct position on the member 11.

A vertical shaft 15 has a threaded end 16 thereof threaded through a threaded bore 17 in the member I I. The shafts 15 are positioned adjacent opposite ends of the member 11 and are arranged in spaced apart parallel relation. The lower end portion of the shaft I5 is threaded at 18 and a pair of nuts 19 are threaded thereon in spaced apart relation to grip a plurality of weights 20 therebetween with the aid of washers 21.

The weights 20 may be removed and replaced with weights of a different number or different total weight as desired.

In the use and operation of the invention the user grasps the hand grips 12 then by swinging the member 11 causes the Weights 20 to rotate about the member 1] with the member 11 turning in the hand grips l2. With the rotational motion continued the user then moves the member 11 through any of various exercises such as overhead lifts from floor, forward curl. reverse curl. kneebends, shoulder press and the like. The motion of the weights and the member produced in this manner provides an unique exercise and strengthens the muscles involved more quickly than the simple lifting of weight would provide.

Having thus described the preferred embodiment of the invention it should be understood that numerous structural modifications and adaptations may be resorted to without departing from the spirit of the invention.

What is claimed is:

I. An exercise apparatus including an elongate generally cylindrical bar, a pair of freely rotatable hand grips mounted in spaced apart relation on said bar adjacent opposite ends thereof, circumferential grooves in said bar at each end of each said hand grips, retainer rings seated in each of said grooves for securing said hand grips against longitudinal movement along said bar, a weight support threaded shafts threaded into each end portion of said bar between the end of said bar and the adjacent hand grip and extending perpendicularly to said bar, weights on said threaded shafts and opposed nuts on each of said threaded shafts detachably securing said weights on said threaded shafts.
