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.
Claims17
A method of making a flexible hand grip comprising:
- (a) forming a tubular core member of flexible material having a plurality of spaced apertures therein;
- (b) disposing an outer tubular member of flexible material over the core member and forming an annular space therebetween;
- (c) assembling the outer tubular member to the core member and closing the axially opposite ends of the annular space;
- and,
- (d) inserting a flexible material of bulk density substantially less than the density of the core and outer member through the apertures into the annular space formed between the core member and outer member.
