Abstract
Abstract A tubular handle for hand tools and the like comprises a grip supporting portion having a hollow open construction at the butt end thereof and a solid preformed plastic plug of material exhibiting dimensional stability at elevated temperatures secured in the open end by a firm pressure fit therewith. A hand cushion grip is molded directly onto the handle and securely conforms to the grip supporting portion and plastic plug, fully encasing both members. The sealed mold utilized in molding the grip contains a multiplicity of perforation-producing pins having individual gas vents associated therewith, the pins and vents being spaced along the longitudinal extent of the mold cavity.

Claims Analysis
Total Claims: 7
Claim 1
Independent Claim
103 words
In an elongated tubular handle for hand tools and the like comprising a grip supporting portion having a hollow open construction at the free end thereof and a hand cushion grip covering the grip supporting portion and free end, the combination including a plug formed of a solid durable plastic material having dimensional stability at elevated temperatures driven into said open end in a secure press fit connection with said handle to fully close said free end, the hand cushion being molded in place over said plug to fully enclose the plug and conformably adhere to the grip supporting portion of the handle.
Claim 2
Dependent Claim
103 words
In an elongated tubular handle for hand tools and the like comprising a grip supporting portion having a hollow open construction at the free end thereof and a hand cushion grip covering the grip supporting portion and free end, the combination including a plug formed of a solid durable plastic material having dimensional stability at elevated temperatures driven into said open end in a secure press fit connection with said handle to fully close said free end, the hand cushion being molded in place over said plug to fully enclose the plug and conformably adhere to the grip supporting portion of the handle.
Claim 3
Dependent Claim
58 words
The tool handle of claim 1 wherein the plug omprises a generally arcuate body portion having an integral radially extending flange on one end thereof, said main body portion being positioned within the tubular handle in press fit relationship therewith and the radial flange cooperatively engaging the end of the handle to limit inward movement of the plug.
Claim 4
Dependent Claim
53 words

Claim 5
Dependent Claim
30 words
The tool handle of claim 1 including a layer of adhesive between the grip and the grip supporting portion of the handle for firmly anchoring the grip to the handle.
Claim 6
Dependent Claim
39 words
The tool handle of claim 1 wherein the molded-in-place grip is provided with a multiplicity of grip facilitating perforations spaced along the length of the grip and extending into the grip for a depth less than the thickness thereof.
