Abstract
A light flexible hand grip and method of making with an inner tubular core of flexible rubber with apertures formed therein and an outer tubular cover disposed over the core with a lighter weight annular flexible foam spacer between the core and outer cover. The spacer may be formed by injecting curable material through the apertures. The apertures may be formed by inserting a mandrel in the core, punching the holes and removing the mandrel.
Claims9
A flexible hand grip comprising:
- (a) a tubular core formed of flexible material and having a plurality of spaced apertures therein;
- (b) an outer tubular member received over the tubular core with an annular space between the tubular core and the outer tubular member, wherein the tubular core has an outwardly extending flange at an end thereof, and the outer tubular member has a substantially closed end formed integrally therewith disposed axially distal the flange such that the axially opposite ends of the annular space are closed;
- and,
- (c) a flexible spacer formed of material having a bulk density substantially less than the tubular core or outer tubular member disposed in the annular space wherein the spacer is a curable material inserted through the apertures and into the annular space.
