Patent number: 11446556Abstract: A lightweight compression molded multicolor golf grip having at least a first section and a second section of differing colors and composed of elastomer compounds joined by cross-linking across a sharply defined cross-color interface having an interface transition zone beyond which there is no mixing of the colors. The grip has a soft feel and unique compression characteristics achieved in some embodiments through the controlled use of an expanding blowing agent in a rubber compound. Achieving the sharply defined cross-color interface is due in part to the use of complementary geometries at opposing interface edges to increase the stability of the interface and reduce the flow during molding associated with the increased viscosity of low density rubber compounds, promote cross-linking of the sections, and better distribute and control the consolidation pressure.Type: GrantFiled: August 3, 2020Date of Patent: September 20, 2022Assignee: Eaton Intelligent Power LimitedInventors: Stephen James Davis, Alex Lee Walls, Wen-Chen Su, Aaron Joseph Michaud, Edward Wang

Publication number: 20210170247Abstract: A flexible grip for a golf club having in one version a groove with an acute angle undercut grove in either or both the inner and outer surface to improve gripability. In another version, either or both of the inner and outer surface may be textured with peaks and valleys with radius less than 0.2 mm. In another version, either or both of the inner and outer surfaces may have a textured surface with raised portions having a height less than 0.3 mm. In another version, either or both the inner and outer surface may have a microtexture with raised portions having a transverse section width not greater than 0.3 mm with a height about 2 multiples of the transverse section width. In another version, the wall of the grip has voids or hollow spaces for improved cushioning for the user's grip.Type: ApplicationFiled: February 22, 2021Publication date: June 10, 2021Applicant: Eaton Intelligent Power LimitedInventors: Stephen James Davis, Gregory William Cavill

Patent number: 10987557Abstract: A flexible elastomeric grip for the shaft of a golf club having an end cap with a cavity for receiving a sensor and/or counterweight. The cap has a durometer hardness equal to or greater than the tubular body portion of the grip and a flange sized to match the larger diameter of the body, with a sleeve engaging the inner periphery of the larger end of the tubular body. In one version of the cap, the sleeve portion is extended in length and has stiffening ribs on the outer surface of the sleeve; and, in another version, the sleeve is shorter and may also have stiffening ribs on the outer surface of the sleeve. In another version of the cap, fibrous material is disposed in the flange and sleeve to increase lateral stiffness without increasing durometer.Type: GrantFiled: February 20, 2020Date of Patent: April 27, 2021Assignee: EATON INTELLIGENT POWER LIMITEDInventors: Stephen James Davis, Gregory William Cavill, Joshua Cliff Stokes, Alex Lee Walls, Andy Allan Arrington

Publication number: 20200406113Abstract: A flexible tubular implement grip with a first section formed of elastomeric material having a first set of properties and a second section having a second different set of properties. An annular interface member is disposed between and abutted and bonded to the first and second section on opposite sides of the interface member. The interface member is fitted on a core bar and inserted therewith in a mold. The materials of different properties are then disposed concurrently in the mold, either for compression molding or by injection and cured in a single molding operation. The interface member may have grooves on the inner or outer periphery to provide positive interlocking engagement of the elastomeric material with the interface member.Type: ApplicationFiled: September 14, 2020Publication date: December 31, 2020Applicant: Eaton Intelligent Power LimitedInventors: Stephen James Davis, Edward Wang

Patent number: 10729953Abstract: A lightweight compression molded multicolor golf grip having at least a first section and a second section of differing colors and composed of elastomer compounds having a density of less than 0.90 g/cc, and joined by cross-linking across a sharply defined cross-color interface having an interface transition zone beyond which there is no mixing of the colors. The grip has a soft feel and unique compression characteristics achieved in some embodiments through the controlled use of an expanding blowing agent in a rubber compound. Achieving the sharply defined cross-color interface is due in part to the use of complementary geometries at opposing interface edges to increase the stability of the interface and reduce the flow during molding associated with the increased viscosity of low density rubber compounds, promote cross-linking of the sections, and better distribute and control the consolidation pressure.Type: GrantFiled: July 3, 2019Date of Patent: August 4, 2020Assignee: EATON INTELLIGENT POWER LIMITEDInventors: Stephen James Davis, Alex Lee Walls, Wen-Chen Su, Aaron Joseph Michaud, Edward Wang

Patent number: 10632356Abstract: An improved golf club grip 10a, 10b, 10c with a well-defined and pronounced reminder rib 20a, 20b, 20c includes in one embodiment of the present disclosure a groove 32 positioned in the exterior surface 34 on each side of or surrounding a ridge 24a that extends lengthwise inside the body 14a of the grip 10a. When the golf grip 10a is installed on a golf club shaft 12, the groove 32 facilitates the flexing of the grip material for forming the reminder rib 20a. In another embodiment of the present disclosure, the grip 10b, 10c is provided with a raised portion 36 of a selected material in a select region on the grip 10b, 10c. When the golf grip 10b, 10c is installed on a golf club shaft 12, the raised portion 36 becomes the reminder rib 20b, 20c.Type: GrantFiled: May 2, 2018Date of Patent: April 28, 2020Assignee: EATON INTELLIGENT POWER, LTD.Inventors: Stephen James Davis, Alex Walls, Andy Arrington, Bruce Miller
