Patent number: 6393950Abstract: The tools (wrenches) of this invention provide a one color instant identification of color coded tools. Preferably, the tools have a portion of their outer surface colored. Typically, the color impregnates the metal or plating during the manufacturing process. Another embodiment is a colored applique, band or sleeve on the outer surface of the tools. The key of this coloring is to identify the tool quickly by coloring a large area of the tool. This provides for quick identification of the tool even if the numerical designations are illegible because of small sizing or dirt obliteration. In a preferred embodiment, virtually the entire tool is colored during manufacturing. In another preferred embodiment, large raised numbers combine with the overall color scheme to make the tools quickly identifiable. Dirting the large colored surface is very unlikely as is obliterating the large raised fractional numbers.Type: GrantFiled: August 3, 1999Date of Patent: May 28, 2002Inventor: Larry G. Crosser

Patent number: RE37190Abstract: A universal handle for household and other hand-held implements, the handle being adapted to ergonomically render the implement to which it is applied useable by individuals who have difficulty in firmly grasping a conventional handle. The universal handle, which is fabricated of elastomeric material having good thermal insulation and cushioning properties, includes an internal cavity to socket the core shank of the implement. The handle has an elliptical cross section, the opposing sides of the handle adjacent its upper end each having a concave depression, in each of which an array of spaced, flexible fins is anchored to define a depressible grip site. When the fingers of a user's hand are clenched about the handle, the internal region of the resultant fist conforms to the form of the handle to provide a good grip thereon, the thumb and forefinger pressing into the grip sites to enhance the user's grip on the handle.Type: GrantFiled: December 4, 1992Date of Patent: May 29, 2001Assignee: General Housewares Corp.Inventors: Davin Stowell, Michael Callahan
