Patent number: 8647462Abstract: A flexible implement grip is formed with an underlist of one rubber compound wrapped with a skin of a second rubber compound with multi-colored rubber based paint or ink air dried thereon and the assembled grip vulcanized in a mold. In one version, the skin pattern is cut from a sheet of cured rubber and curable adhesive employed with the wrapping. In another version, the multi-colored ink or paint is air dried on an uncured sheet prior to cutting the skin pattern; and, no adhesive is employed with the wrapping and bonding to the underlist occurs during final vulcanizing.Type: GrantFiled: September 24, 2012Date of Patent: February 11, 2014Assignee: Eaton CorporationInventors: Wen-Chen Su, David Keith Gill, Billy Dee Wood

Patent number: 8641553Abstract: A flexible golf club grip having a brightly colored underlist of elastomeric material of a certain durometer and an outer layer of less durometer. The outer layer may have voids to expose portions of the underlist or the underlist may have portions thereof extend into the voids during molding but remain recessed below the surface of the outer layer. In another version, a brightly colored cover layer is molded over the underlist and a spiral wrapped strip of softer elastomer is molded thereover with the edges of the strip spaced to expose the original strip of the cover layer.Type: GrantFiled: April 15, 2013Date of Patent: February 4, 2014Assignee: Eaton CorporationInventors: David Keith Gill, Bruce Allan Miller, Daniel Francis Koehler

Patent number: 8424164Abstract: A flexible molded grip for an implement handle having a pattern on the surface of portions raised above adjacent areas, with the surfaces of the raised portions textured. The raised textured portions may extend in the range of about 0.5 mm to 2 mm above the intermediate smooth portions. The area of each of the raised portions may be in the range of about 100-200 percent (%) of the area of the intermediate spaces. The pattern of raised portions may include patterns such as polygonal, circular, oval and elliptical patterns. The method includes forming raised portions in a mold and forming textured surfaces on the raised portions after removal from the mold.Type: GrantFiled: July 5, 2011Date of Patent: April 23, 2013Assignee: Eaton CorporationInventor: David Keith Gill

Patent number: 8296907Abstract: A light weight flexible hand grip and method of making with a single piece precursor grip member having a tubular sleeve portion connected with a tubular grip portion with a wall situated therebetween. An alternate embodiment includes the tubular grip portion attached proximate an open end of the tubular sleeve portion. A core portion is disposed on an outer surface of the tubular sleeve portion and the tubular grip portion is positioned back over the tubular sleeve portion securing the core portion within an annular cavity to form the light weight hand grip.Type: GrantFiled: May 15, 2009Date of Patent: October 30, 2012Assignee: Eaton CorporationInventors: David Keith Gill, Billy Dee Wood

Patent number: 8296908Abstract: A light flexible hand grip and method of making with an inner tubular core of flexible rubber with apertures formed therein and an outer tubular cover disposed over the core with a lighter weight annular flexible foam spacer between the core and outer cover. The spacer may be formed by injecting curable material through the apertures. The apertures may be formed by inserting a mandrel in the core, punching the holes and removing the mandrel.Type: GrantFiled: June 16, 2011Date of Patent: October 30, 2012Assignee: Eaton CorporationInventor: David Keith Gill

Patent number: 8294066Abstract: A heated element includes a thermally and electrically conductive polymer in a shaped or spaced arrangement. The spaced arrangement has at least one string of material with ends that are configured to be electrically connected to a power source. A first end is connected to a positive terminal of the power source while the other end is connected to a negative terminal of the power source. A hand grip includes the heating element disposed on an inner layer, and may include an outer layer. The spaced arrangement may be disposed between the inner and outer layer for indirect heating applications. Alternatively, portions of the spaced arrangement may protrude from either the inner layer or the outer layer for direct heating applications. The heated element may be used with a number of devices, including but not limited to, golf club grips, hand grips, heating pads, blankets, or other applications.Type: GrantFiled: November 19, 2010Date of Patent: October 23, 2012Assignee: Eaton CorporationInventors: David Keith Gill, Billy Dee Wood
