Abstract

See full text

A one-piece injection molded tool handle having a body with a tang end for attaching to a tool and a handle end with a D-handle molded to the body. The body has a hollow defined by an inside generally frustoconical surface extending from the tang end outwardly to the handle end and diverges outwardly at an angle of about 1/2.degree.. The outside surface of the body is defined by a first outside generally frustoconical surface extending from the tang end and diverges downwardly and outwardly at an angle of about 3/4.degree. toward the handle end. A second outside surface extends from the first frustoconical outside surface to the handle end and diverges outwardly at an angle of about 1/4 degree. The frustoconical surfaces result in the wall of the handle being thickest at an intermediate part of the handle. A cylindrical tool receiving extension is integrally attached to the tang end of the handle body. The D-shaped handle is offset from an extension of the walls defining the frustoconical surface by about two inches.
