Embodiment Construction

[0024] exist figure 1 In , a barbell pad 16 is shown together with a barbell 17 having an elongated bar 18 with weight plates 19 detachably mounted on opposite ends of the bar.

[0025] Such as Figure 2-5 As further shown, the barbell liner 16 has an elongated body 21 of injection molded EVA foam which is mounted on a bar which passes through an axially extending opening 22 in the body. The pad has a circular cross-section, with an inner diameter corresponding to the diameter of the bar, and an outer diameter that varies along the length of the pad in accordance with the contour of the body against which the bar will rest. In the embodiment shown, the opening 22 has a straight cylindrical side wall 23, but it may have a different profile corresponding to the shape of another bar.

[0026] The outer surface 24 of the bar pad body has a cylindrical central portion 26 of substantially uniform diameter, concavely curved portions 27, 27 extending from opposite ends of the centra...

Abstract

Pad that mounts on the bar of a barbell and spreads forces exerted by the bar over a larger area of the shoulders, neck, and / or chest of a person upon which the bar is resting. The pad has an elongated body of resilient, highly compressible injection molded EVA foam having an annular cross section, an inner surface that grips the bar and holds the pad in place on the bar, and an outer surface withan ogee curvature that conforms to the contour of the shoulders, neck, and / or chest of the person using the barbell.

Description

technical field [0001] The present invention relates generally to sports and fitness equipment, and more particularly to a pad that mounts on a barbell bar and that distributes the force exerted by the bar across the shoulders, neck of a person upon which the bar rests and / or on larger areas of the chest. Background technique [0002] Barbell pads are used to perform a variety of movements, such as knee bends or squats, in which the user places a loaded barbell across his or her shoulders and back, or across the chest and shoulders while performing shoulder compression exercises . These pads are usually made of some type of extruded foam, and their main purpose is to provide cushioning between the bar and the body, thereby improving comfort or relieving the discomfort of a bar weighing on the user . [0003] The most basic type of bar pad currently available consists of a length of tubular foam that slides over the end of the bar or creates a slit opening along one side, ...
