Patent ID: 8647243

Claim:
An exercise device weight section for mounting to a lifting bar, the weight section having an outer circumferential surface and comprising an outer skin at least partially around the outer circumferential surface of the weight section; wherein the outer skin comprises a plurality of resilient projections extending from at least part of the outer circumferential surface of the weight section; the plurality of projections are disposed only in a discrete circumferential region of the circumferential surface of the weight section, and wherein the outer skin has in interior surface secured in direct surface-to-surface contact to the circumferential surface of the weight section, the plurality of resilient projections being disposed in direct radial opposition to the interior surface portion of the outer skin in direct surface-to-surface contact with the circumferential surface of the weight section so that radially directed impact forces applied to any of the resilient projections are transferred directly through the outer skin to the weight section without radial displacement of the interior surface; and wherein a circumferential spacing is defined between adjacent resilient projections, the circumferential spacing being irregular with respect to at least some of the adjacent resilient projections; characterized in that the outer skin includes a peripheral rim projection around an axial end circumference of the weight section which is configured to protect the projections from lateral forces, the peripheral rim projection being disposed in direct radial opposition to the interior surface portion of the outer skin in direct surface-to-surface contact with the circumferential surface of the weight section so that a radially directed impact force applied to the peripheral rim projection is transferred directly through the outer skin to the weight section without radial displacement of the interior surface.
