Publication number: 20130102414Abstract: A hollow golf club is provided having an outer shell and an inner frame. The outer shell comprises one or more lightweight members, such as the crown or the skirt, and preferably fits within an envelope of about 5 inches×5 inches×2.8 inches. The inner frame fits within a smaller envelope and sits on the sole of the club head. One or more weights are located either on or within the inner frame to optimize the moment of inertia of the club head about both the vertical axis running through the center of gravity or geometric center of the club head, hereinafter referred to as the “y-axis,” and the axis running through the center of the shaft of the golf club, hereinafter referred to as the “hosel axis.” The weights can be attached to the inner frame or can be distributed within the inner frame.Type: ApplicationFiled: December 13, 2012Publication date: April 25, 2013Applicant: ACUSHNET COMPANYInventor: ACUSHNET COMPANY

Publication number: 20130095956Abstract: The present invention is directed to golf balls consisting of a multi-layer core and a cover. The multi-layer core consists of a center and an outer core layer that are both soft relative to a hard rubber intermediate core layer. The outer core layer is preferably thin relative to the center and the outer core layer. The multi-layer core includes at least one layer formed from a relatively soft HNP composition and at least one layer formed from a relatively hard HNP composition.Type: ApplicationFiled: December 3, 2012Publication date: April 18, 2013Applicant: ACUSHNET COMPANYInventor: Acushnet Company

Publication number: 20130072325Abstract: The present invention provides a method for arranging dimples on a golf ball surface in which the dimples are arranged in a pattern derived from at least one irregular domain generated from a regular or non-regular polyhedron, and particularly a dipyramid. The method includes choosing control points of a polyhedron, generating an irregular domain based on those control points, packing the irregular domain with dimples, and tessellating the irregular domain to cover the surface of the golf ball. The control points include the center of a polyhedral face, a vertex of the polyhedron, a midpoint or other point on an edge of the polyhedron and others. The method ensures that the symmetry of the underlying polyhedron is preserved while minimizing or eliminating great circles due to parting lines.Type: ApplicationFiled: November 13, 2012Publication date: March 21, 2013Applicant: ACUSHNET COMPANYInventor: Acushnet Company

Publication number: 20130072316Abstract: A method relating to an improved fitting system for a golf club shaft is disclosed herein. More specifically, the present invention utilizes specific data gathered from the golfer's golf swing itself to determine the best performing golf club shaft for this particular golf swing. Even more specifically, the present invention relates to the utilization of infrared motion capturing cameras to record the location data of a golf club shaft throughout a swing. Based on the location data captured, one or more dynamic behavioral characteristics can be calculated to determine one or more preferred shaft characteristics. Using the preferred shaft characteristics, a shaft can be recommended for the golfer having this particular golf swing. The current inventive fitting methodology is preferred to the archaic fitting method of using data gathered from the result orientated ball flight data together with a tedious process of having to try numerous different shafts.Type: ApplicationFiled: November 15, 2012Publication date: March 21, 2013Applicant: ACUSHNET COMPANYInventor: Acushnet Company

Publication number: 20130065708Abstract: The present invention provides a method for arranging dimples on a golf ball surface that significantly improves aerodynamic symmetry and minimizes parting line visibility by arranging the dimples in a pattern derived from at least one irregular domain generated from a regular or non-regular polyhedron. One or more irregular domains may have an initial dimple sub-pattern of nearest neighbor dimples wherein the dimple sub-pattern is packed in one or more irregular domains; and the unfilled regions of the irregular domains are packed with dimples and the irregular domains are tessellated around the golf ball surface.Type: ApplicationFiled: November 9, 2012Publication date: March 14, 2013Applicant: ACUSHNET COMPANYInventor: ACUSHNET COMPANY

Publication number: 20130045820Abstract: A golf ball comprising: an inner core having a compression of less than about 60; at least one outer core layer (surrounding the inner core or an optional intermediate layer) having a hardness of at least about 55 Shore D and a specific gravity greater than a specific gravity of the inner core; and a cover surrounding the outer core layer; at least one of the inner core, intermediate layer and outer core layer comprising a partially or fully neutralized ionomer; and the inner core having a hardness less than a hardness of the at least one outer core layer. Additionally, either the cover has a Shore D hardness of at least 60 and a specific gravity less than the specific gravity of the at least one outer core layer, or the inner core comprises a partially or fully neutralized ionomer and a specific gravity less than 1.0.Type: ApplicationFiled: October 22, 2012Publication date: February 21, 2013Applicant: ACUSHNET COMPANYInventor: Acushnet Company

Publication number: 20130035175Abstract: An iron-type golf dub includes a conventional-weight section, a lightweight section and a heavyweight section. The conventional-weight section includes the hitting face and at least a portion of the hosel. The heavyweight section, made of a denser material than the conventional-weight section, includes the sole and an optional back flange. The lightweight section, made of a material less dense than either of the other sections, includes a core to which the other two sections are secured, such as by co-molding the core to the other two sections. The heavyweight section includes anchoring structures to which the lightweight section can securely attach. This arrangement maintains the overall weight of the club head compared to a similarly proportioned conventional club head while shifting the center of gravity low and aft. As such, the club head provides benefits such as forgiveness for thin shots, heel/toe shots, and provides longer drives with less roll.Type: ApplicationFiled: October 9, 2012Publication date: February 7, 2013Applicant: ACUSHNET COMPANYInventor: ACUSHNET COMPANY
