Abstract
A collar for a barbell, the collar having a first collar portion having a body extending along a curve, wherein the body includes: an outer radial surface; an inner radial surface; a channel extending between the outer radial surface and the inner radial surface; a blockage disposed within the channel, wherein the blockage comprises an elastomeric material; and a first pad extending radially inward from the inner radial surface of the first collar portion, wherein first pad includes the same elastomeric material of the blockage, and wherein the first pad is integral with the blockage disposed within the channel.

A collar for a barbell, the collar comprising:
- a first collar portion having a body extending along a curve, wherein the body includes:
- an outer radial surface;
- an inner radial surface;
- a channel extending between the outer radial surface and the inner radial surface, wherein the channel forms a through-hole from the outer radial surface to the inner radial surface;
- a blockage disposed within the channel, wherein the blockage comprises an elastomeric material;
- and
- a first pad extending radially inward from the inner radial surface of the first collar portion,
- wherein the first pad includes the same elastomeric material of the blockage, and wherein the first pad is integral with the blockage disposed within the channel.
A collar for a barbell, the collar comprising:
- a first collar portion having a body extending along a curve, wherein the body includes:
- an outer radial surface;
- an inner radial surface;
- a channel forming a through-hole from the outer radial surface to the inner radial surface;
- and
- a first pad extending radially inward from the inner radial surface of the first collar portion,
- wherein the first pad includes an elastomeric material mechanically interlocked to the inner radial surface of the first collar portion, and
- wherein the channel is at least partially filled with the elastomeric material of the first pad.
A method of manufacturing a collar for a barbell, the method comprising:
- injecting an elastomeric material into one or more channels disposed in an outer radial surface of a first portion of the collar, such that the elastomeric material flows through the one or more channels and into a recess of an inner radial surface of the first portion of the collar;
- and
- solidifying the elastomeric material in the one or more channels and the recess to produce a pad at least partially disposed within the recess and mechanically interlocked to the first portion of the collar.
