Abstract:
A telescoping handle including a plurality of telescoping hollow tubes that are nested within each other and dimensioned to provide a gap between each adjacent pair of nested tubes. At least one shim is secured to the outer circumferential surface of one end of at least one of the tubes. The shim has a thickness sufficient to fill the gap between the adjacent pair of tubes whereby the shim is flush against the inner surface of the adjacent hollow tube. The other end of an adjacent tube has a tapered portion which has an inner circumferential surface that is flush against the outer circumferential surface of the adjacent telescoping tube.
