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

The alignment channel and the alignment projection are designed and configured to provide a visual and tactile indication as to whether the golf grip is in the proper, or intended, orientation with respect to a golf club face. The system includes a golf grip and an alignment device. The alignment device is releasably secured to the golf grip and includes a feedback element. The feedback element provides an indication as to whether the golf grip is in a desired position with respect to the golf club face.Type: GrantFiled: September 24, 2008Date of Patent: December 29, 2009Inventor: Lanny L. Johnson

Publication number: 20090247315Abstract: A golf putter constriction and a method for using are presented. A defined gripping plane is positioned parallel to a general body position relative to a hip-plane, or shoulder-plane, and also generally parallel to the face of the club at a slight angle parallel to a shaft-angle. This constriction arrangement repositions the grip location and hence body and arm positioning for a user and creates a physiological bone alignment along one of the user's arms (left or right depending upon dominance swing), which allows an alternative rigid-arm swing through contact with the ball for improved ball-contact alignment.Type: ApplicationFiled: March 24, 2009Publication date: October 1, 2009Inventor: ANDREW KOSSOWSKY

Publication number: 20090143163Abstract: A golf club (2) includes a head (4), a shaft (6) and a grip (8). At least one siping groove (g1) is provided on a surface of the grip (8). The siping groove (g1) is bent in a direction (Dd) of a depth of the grip. A width (Wg) of the siping groove (g1) is set to be equal to or greater than 0.15 mm and is equal to or smaller than 1.5 mm. It is preferable that an opening edge (e1) of the siping groove (g1) should be bent. The width (Wg) is more preferably equal to or greater than 0.20 mm. The width (Wg) is more preferably equal to or smaller than 1.4 mm and is further preferably equal to or smaller than 1.3 mm. A depth (F1) of the siping groove (g1) is preferably equal to or greater than 0.5 mm and is preferably equal to or smaller than 3.5 mm.Type: ApplicationFiled: September 24, 2008Publication date: June 4, 2009Inventor: Tomio Kumamoto

Patent number: 7537532Abstract: An implement for swinging in one's hands has an implement body. A handle extends from the implement body. The handle consists of two elongate handle members that generally abut against the other along substantially the length of the handle members. The handle members have inwardly sloped, converging sidewalls along at least one side of the handle where the handle members abut to form a longitudinal groove along substantially the length of the at least one side of the handle. The converging sidewalls are at least one of convex arcuate or planar surfaces. A method of swinging the implement may be performed by gripping the handle with both hands so that the hands are in a closely adjacent or touching adjacent position with at least the tip of one or more fingers lie generally in or along the longitudinal groove. The implement is then swung while holding the implement in both hands.Type: GrantFiled: May 16, 2007Date of Patent: May 26, 2009Inventor: Carl D. Young

Publication number: 20090048036Abstract: The disclosure herein includes a grip for a golf club with a flexible tube and a layered sheet. The tube includes a tubular body and raised portions extending from the tubular body. The outer surface of the raised portions cooperates with the layered sheet to form a gripping surface. The grip reduces impact shock and provides a feeling of tackiness while providing increased variation in the physical characteristics of the gripping surface.Type: ApplicationFiled: August 14, 2007Publication date: February 19, 2009Inventor: Ben Huang

Patent number: 7485050Abstract: A micropattern grip surface for use on a grip, and particularly a grip for a golf club, wherein the pattern includes alternating upstanding ridges and grooves between the ridges. In a preferred embodiment, the ridges extend with a generally longitudinal direction of extension component on the grip with a generally circumferential direction of extension component and also may be parallel. The ridges in an embodiment zigzag along the longitudinal direction. In an embodiment, at intersections or bends between the zig and the zag line elements, additional free end barbs extend from the intersections. The density, width and height of the line elements of the ridges are selected to provide drag on the hand or object gripping the grip, preferably in both the longitudinal and circumferential directions, and to give the grip a velvety feel. Alternatively, each of the ridges is comprised of some line elements.Type: GrantFiled: January 17, 2006Date of Patent: February 3, 2009Assignee: Grip Surface Technologies, Inc.Inventor: Timothy Rose

Publication number: 20090023512Abstract: The golf club grip includes an upper portion and a lower portion. The upper portion has a forward-facing aspect and a rearward-facing aspect, the forward-facing aspect preferably having a substantially arcuate contour. The forward-facing aspect is adapted to support the user's thumb during use. The rearward-facing aspect includes first and second surfaces joined together at a vertex, the first and second surfaces being acutely angled with respect to one another. The first and second surfaces are adapted for gripping by the user's fingers. The golf club grip has an axial bore formed therein, and the golf club grip is preferably symmetric about a plane of symmetry extending between the vertex and a central point of the forward-facing aspect. The axial receives the upper end of a golf club shaft.Type: ApplicationFiled: July 18, 2008Publication date: January 22, 2009Inventor: Jack Watson

Publication number: 20080248892Abstract: An improved putting method and apparatus include an improved putter and a swinging stance of specific features. The improved putter includes a putter head, a shaft and a handle. The putter head is attached to one end of the shaft and the handle is formed on the other end of the shaft. The handle includes a gripping portion, which is terminated with a substantially spherical ball. The elements of the swinging method include resting a back of one hand against a leg thigh; placing the substantially spherical ball into the palm of the one hand; grasping the spherical ball with the fingers and thumb of the one hand; grasping the gripping portion with the other hand; and retracing an arcuate path to strike the golf ball. Preferably, the one hand is closest to the target. The putter head is preferably swung parallel to the ground.Type: ApplicationFiled: April 9, 2007Publication date: October 9, 2008Inventor: Jimmy H.
