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

Patent number: 11266890Abstract: A flexible tubular golf club grip is formed of elastomeric material having a substantially closed end with an end cap. The tubular portion is formed of substantially softer material than the end cap and has disposed on opposite sides axially spaced discrete areas of macro-texture having spaced raised portions giving a quilt-like appearance. The discrete areas of macro-texture are disposed peripherally spaced on opposite sides of the grip. The end cap has an extension which closely inter-fits the inner periphery of the tubular portion and provides support therefor proximate the substantially closed end. The cap extension has axially extending protrusions peripherally spaced on the top and bottom of the cap which are flush with the outer surface of the tubular portion.Type: GrantFiled: July 31, 2020Date of Patent: March 8, 2022Assignee: Eaton Intelligent Power LimitedInventors: Gregory William Cavill, Bruce A. Miller, Craig R. Balnis, James Ledford, Jonathan C. Neal, Aaron J. Michaud, Alex Lee Walls

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: 20140076487Abstract: A method of forming a flexible implement grip utilizing a cured underlist. A sleeve is formed of uncured sheet stock laminated with a carrier having a design thereon of heat transferable colored ink. The laminate is cut to a pattern, wrapped on a core bar and heated in a mold with textured/embossed cavities. The design is heat transferred to the sheet stock in the molding and upon removal from the mold, the carrier and core bar are removed to leave a seamless tubular sleeve with the colored design on the outer surface. The sleeve is then assembled on the underlist and adhesively secured thereon forming a finished grip.Type: ApplicationFiled: September 14, 2012Publication date: March 20, 2014Applicant: Eaton CorporationInventors: Wen-Chen Su, Alex Lee Walls, Min-Chia Wang, Meng-Feng Tsai

Publication number: 20130248089Abstract: In one version of the method of making a flexible grip, a thin film carrier with negative of desired colored image is laminated to an uncured skin sheet and flat cured in a mold to heat transfer the image to the skin sheet and concurrently form a textured surface. The carrier is peeled away and the skin sheet wrapped and adhesively bonded to a cured underlist. In another version, the thin film carrier with negative of desired image is laminated on an uncured skin sheet which is wrapped on a cured underlist. The wrapped underlist is cured in a textured mold cavity to concurrently, in a single molding operation, heat transfer the image of the skin sheet from a textured surface and cure the skin sheet in place on the underlist.Type: ApplicationFiled: March 21, 2012Publication date: September 26, 2013Inventors: Wen-Chen Su, Alex Lee Walls, Min-Chia Wang, Meng-Feng Tsai

Patent number: 8485916Abstract: An apparatus and method for forming a reminder rib on a hand grip using an improved core bar having an axial groove extending lengthwise on a molding portion of the core bar for forming a rib on an interior surface of the hand grip. When the hand grip is installed on a shaft or handle, the interior rib forms a reminder rib on an underside of the hand grip.Type: GrantFiled: May 22, 2009Date of Patent: July 16, 2013Assignee: EatonInventors: David Keith Gill, Alex Lee Walls

Patent number: 8371956Abstract: A golf grip apparatus includes a pre-molded cap that is fixedly attached to a molded outer sleeve. The golf grip is adapted to be mounted onto the proximal end of a golf club shaft. The golf grip may be permanently mounted onto the golf club shaft, with the outer sleeve of the grip being disposed around the outer circumference of the golf club shaft and the pre-molded cap of the grip being disposed at the most proximal end of the shaft. The outer sleeve may have a predetermined wall thickness that is sufficiently thin to provide a hollow area between the grip's outer sleeve and the club's shaft, when the grip is in use, thus reducing the weight of the grip. Spacers may be created on the inner surface of the grip so that when the grip is mounted onto a shaft, the spacers may assist in maintaining the position of the golf club shaft in the grip.Type: GrantFiled: December 11, 2009Date of Patent: February 12, 2013Assignee: Eaton CorporationInventor: Alex Lee Walls
