Abstract

See full text

A tool handle includes a tapered shaft retainer which is dimensioned for insertion into the eyehole of a tool head, a high strength handle shaft bonded within the shaft retainer, and a grip which ensheathes the handle shaft. The shaft retainer includes an outer surface portion generally corresponding to a portion of the eyehole, an upper enlarged portion which is incapable of passing through the eyehole, and a slightly tapered inner cavity. The shaft retainer is inserted into the eyehole from the top end thereof, a measured adhesive is placed into the inner cavity, and then the handle shaft is pressed therein through a lower end of the eyehole. In order to improve the bond between the shaft retainer and the upper end of the handle shaft, keyways are provided on the upper end of the shaft and within the inner cavity of the shaft retainer. The grip may be molded directly onto the handle shaft prior to assembly of the shaft retainer to the handle shaft, or the grip may be slidably received onto the handle shaft afterwards and then attached thereto. In such a case, in one preferred method of assembly, an adhesive compound is placed within the grip prior to its being slid onto the handle shaft. In another preferred method of assembly, a mechanical attachment is utilized between the girp and the handle shaft.
