Abstract

A weight plate for fitness weightlifting that provides an ergonomic gripping device is described. The ergonomic weight plate comprises a disc-shaped member having a center through-hole for positioning the weight plate onto a barbell. The disc-shaped member further comprises at least one ergonomic gripping cutout located around the periphery of the disc-shaped member. The gripping cutouts are adapted to receive human fingers to facilitate lifting of the weight plate. The ergonomic gripping cutouts each have an outer periphery and an inner periphery. A portion of the outer periphery of the cutouts is convex to properly conform the gripping cutout to the shape of a human hand. In a second embodiment the gripping cutout has a grip enhancement strip located on the inner surface of the outer periphery of the gripping cutouts.

Claims (27)

1. An ergonomic weight plate, comprising:

a unitary disc-shaped member having a rounded periphery and a center through-hole for positioning the disc-shaped member onto a barbell; and

at least one handle, each said at least one handle being integrally formed in said disc-shaped member, each said at least one handle having an ergonomic gripping surface defining a wall of a cutout in said disc-shaped member, each said ergonomic gripping surface having a convex curvature defined in said disc-shaped member so that convex curvature protrudes inward towards the center through-hole;

whereby each said ergonomic gripping surface is adapted to receive fingers of a hand of a weightlifter in order to facilitate lifting of said disc-shaped member;

wherein the convex curvature of said ergonomic gripping surface conforms to the fingers of the weightlifter.

2. The weight plate according to claim 1 , wherein said disc-shaped member has a known, defined weight, whereby the weightlifter is able to add a known weight increment onto the barbell.

3. The weight plate according to claim 2 , wherein said disc-shaped member has a weight in a range between about 2.5 and 100 pounds.

4. The weight plate according to claim 1 , wherein each said ergonomic gripping surface is positioned proximate to the rounded periphery;

whereby the fingers of the weightlifter are positioned adjacent said ergonomic gripping surface as the hand grasps the rounded periphery of said disc-shaped member.

5. The weight plate according to claim 1 , further comprising a grip enhancement strip attached to each said ergonomic gripping surface of each said at least one handle.

6. The weight plate according to claim 5 , wherein said grip enhancement strip further comprises a plurality of finger receiving slots, each of said finger receiving slots being adapted to fit a single finger for improved gripping of said weight plate.

7. The weight plate according to claim 1 , wherein said disc-shaped member is made from materials selected from the group consisting of cast iron having a urethane coating, cast iron having a rubber coating, cast iron having a powder paint coating and hard plastic filled with sand.

8. An ergonomic weight plate, comprising:

a unitary disc-shaped member having a rounded periphery and a center through-hole for positioning the disc-shaped member onto a barbell;

at least one handle, each said at least one handle being integrally formed in said disc-shaped member, each said at least one handle having an ergonomic gripping surface defining a wall of a cutout in said disc-shaped member, each said ergonomic gripping surface having a convex curvature defined in said disc-shaped member so that convex curvature protrudes inward towards the center through-hole; and

a grip enhancement strip disposed on each said ergonomic gripping surface, each said grip enhancement strip having a plurality of finger receiving slots;

whereby each said ergonomic gripping surface is adapted to receive fingers of a hand of a weightlifter in order to facilitate lifting of said disc-shaped member;

wherein the convex curvature of said ergonomic gripping surface conforms to the fingers of the weightlifter.

9. The weight plate according to claim 8 , wherein said disc-shaped member has a known, defined weight, whereby the weightlifter is able to add a known weight increment onto the barbell.

10. The weight plate according to claim 9 , wherein said disc-shaped member has a weight in a range between about 2.5 and 100 pounds.

11. The weight plate according to claim 8 , wherein each said ergonomic gripping surface is positioned proximate to the rounded periphery;

whereby the fingers of the weightlifter are positioned adjacent said ergonomic gripping surface as the hand grasps the rounded periphery of said disc-shaped member.

12. The weight plate according to claim 8 , wherein said disc-shaped member is made from materials selected from the group consisting of cast iron having a urethane coating, cast iron having a rubber coating, cast iron having a powder paint coating and hard plastic filled with sand.

13. The weight plate according to claim 1 , said at least one handle further includes a plurality of handles, wherein each handle has said convex curvature of said ergonomic gripping surface.

14. The weight plate according to claim 13 , wherein said plurality of handles is at least four handles.

15. The weight plate according to claim 8 , said at least one handle further includes a plurality of handles, wherein each handle has said convex curature of said ergonomic gripping surface.

16. The weight plate according to claim 15 , wherein said plurality of handles is at least four handles.
