Dumbbell with antimicrobial handle
View Patent ↗A dumbbell having an antimicrobial handle comprises a bar having a pair of end regions, and extending generally longitudinally therebetween along a generally central axis, weight plate masses mounted at the end regions and mechanically secured thereto, and a pair of collars located at longitudinally opposed positions on bar to define a handle region therebetween. A handle is located within the handle region and includes a generally tubular grip surface member supported by the bar and formed from an antimicrobial copper alloy, the generally tubular grip surface member extending generally axially between longitudinally spaced-apart end regions. The pair of longitudinally-spaced generally annular collars have axially-inwardly extending flange portions sized and structured to substantially circumscribe the end regions of the generally cylindrical grip surface member and to securely capture the end regions between the flange portions and the bar.
1. A dumbbell comprising:
a bar having a pair of end regions, and a central region extending generally longitudinally therebetween along a generally central axis, the bar having a shoulder at the interface of the central region and each end region;
weight plate masses mounted at the end regions and mechanically secured thereto; and
a pair of annular collars located at longitudinally opposed positions on the bar to define a handle region therebetween,
a handle being located within the handle region and including a generally tubular grip surface member supported by the bar and formed from an antimicrobial copper alloy, the generally tubular grip member extending generally axially between longitudinally spaced-apart end regions and having a crimped end portion overlying the shoulders that is sufficiently reduced dimensionally to create a securing press fit against the bar,
the pair of longitudinally-spaced generally annular collars having axially-inwardly extending flange portions sized and structured to substantially circumscribe the crimped end regions of the generally cylindrical grip surface member.
2. The dumbbell of claim 1 wherein the antimicrobial copper alloy is a cuprous nickel alloy.
3. The dumbbell of claim 2 wherein the collars have crimped flanges overlying the shoulders that are sufficiently reduced dimensionally to create a securing press fit between the generally tubular grip surface member and the bar and securely capture said end regions between the flange portions and the bar.
4. The dumbbell of claim 2 wherein the alloy contains approximately 80% copper.
5. The dumbbell of claim 2 wherein the alloy contains approximately 18-20% nickel.
6. The dumbbell of claim 1 the axially-inward extending flange portions are sized and structured to securely compress the generally tubular grip surface member between the flange portions and the bar.
7. The dumbbell of claim 6 wherein the end regions of the generally tubular grip surface member are captured between the flange portions and the bar via a diameter-reduction operation imposed on the flange regions.
8. The dumbbell of claim 1 wherein the collars are made from an antimicrobial copper alloy.
