Patent number: 5421931Abstract: A composite tool handle includes one or more load-bearing jackets surrounding a core of lightweight or reinforcing material. The interface between the core and the jacket is corrugated to increase the flexural strength of the tool handle while minimizing weight. The composite tool handle is manufactured by pultrusion wherein the core having a corrugated outer surface is fed through a pultrusion die tube. Resin coated fibers are channeled into the space between the core and the die tube for compression and heating to form a fiber-resin jacket having an internal surface conforming to the shape of the core for key-lock engagement therewith. The outer surface of the fiber-resin jacket can be formed with a corrugated or other discontinuous surface shape by placing one or more external mold members into the space between the resin coated fibers and the die tube for pultrusion therewith through the die tube, and for separation from the fiber-resin jacket upon exiting the die tube.Type: GrantFiled: April 8, 1993Date of Patent: June 6, 1995Inventor: Joseph A.

Patent number: 4617697Abstract: A handle adapter for hand molding around an existing handle and constructed in a manner enabling the user to shape the external surface of the adapter to conform to the grip of the user's hand. The material to be molded is contained in a pouch having flexible walls and end closures. The size of the pouch is such that the total volume which it could contain is much larger than the volume of the moldable material therein. One half of the pouch has a cross-sectional area smaller than the cross-sectional area of the other half, whereby the smaller cross-section half of the pouch can be pushed inside the larger cross-section half of the pouch and the material therebetween becomes trapped between two concentrically positioned flexible walls. When the walls of the smaller half pouch are supported by a solid structure, the moldable material then envelops such structure.Type: GrantFiled: August 1, 1985Date of Patent: October 21, 1986Inventor: Constant V.

Patent number: 4393539Abstract: An overhandle for enclosing the handle or the shank of a tool, such as a dental tool. The overhandle is formed of two mating semi-cylindrical sections having respective forward end faces which are confrontingly opposed in the opened condition and are in a single plane in the assembled closed condition. Laterally spaced apart hinges interlock the sections at their forward end faces. An elongated channel is respectively formed in each of the sections and extends through the forward end face of the respective section. The channels matingly confront in the assembled closed condition to define an internal chamber with an open forward end so that the chamber receives the end of the tool with the remaining tool portion axially extending through the open forward end. A coupling mechanism is provided for retaining the sections in the assembled closed condition. In modified embodiments, the same overhandle can enclose either the handle of one tool or the shank of another tool.Type: GrantFiled: December 9, 1980Date of Patent: July 19, 1983Assignee: Ipco CorporationInventor: Bernard Weissman
