GOLF CLUBS

CROSS-REFERENCE TO RELATED APPLICATION

This application claims priority from United States provisional application No. 60/724,162, filed 6 October, 2005, the entire disclosure of which is incorporated herein by reference for purposes.

BACKGROUND OF THE INVENTION Field of the Invention

This invention relates to golf clubs. Introduction to the Invention

The distribution of weight in a golf club, especially its head, has an important effect on the way in which a golf club performs. Different golfers swing clubs in different ways, and for optimum results, each golfer should use golf clubs having a weight distribution suited to his or her own particular swing. Various ways of adjusting weight distribution within a golf club head are described in U.S. Patent Nos. 6,739,983, 6,773.360 and 6,826,619 and in U.S. Patent Publication Application Nos. 2005/0026714, 2005/0043112, 2005/0009627 and 2004/0242343. The entire disclosure of each of those patents and patent publications is incorporated herein by reference for all purposes.

SUMMARY OF THE INVENTION

A first discovery of the present invention is that the weight distribution of a golf club can be adjusted through the use of a convertible member which can be reversibly converted between first and second shapes, the weight distribution being fixed when the component is in the first shape, and the weight distribution being adjustable when the component is in the second shape. A second discovery of present invention is that the weight distribution of a golf club can be adjusted through the use of a weight member which can be fixed in a first position in relation to the remainder of the club, and, if not so fixed, can be moved slidably along a location member forming part of the golf club into a second position in which the weight member can be fixed in relation to the remainder of the club.

These discoveries are also applicable to other assemblies in which the weight distribution is an important factor, including for example other handheld sporting instruments such as rackets for tennis, racquetball, squash, and other ballgames; baseball bats; wheels of all kinds; and bicycle frames.

It is to be understood that the disclosure of the invention in this specification includes all appropriate combinations of such particular features. For example, where a particular feature is disclosed in connection with a particular discovery, a particular aspect, a particular embodiment, or a particular Figure, that feature can also be used in connection with other particular discoveries, aspects, embodiments and Figures (except where the context excludes that possibility), and in the invention generally.

The term "comprises" and grammatical equivalents thereof are used herein to mean that other elements (i.e. components, ingredients, steps etc.) are optionally present. For example, an assembly "comprising" (or "which comprises") components A, B and C can contain only components A, B and C, or can contain not only components A, B and C but also one or more other components. Where reference is made herein to a method comprising two or more defined steps, the defined steps can be carried out in any order or simultaneously (except where the context excludes that possibility), and the method can include one or more other steps which are carried out before any of the defined steps, between two of the defined steps, or after all the defined steps (except where the context excludes that possibility). The term "at least" followed by a number is used herein to denote the start of a range beginning with that number (which may be a range having an upper limit or no upper limit, depending on the variable being defined). For example "at least 1" means 1 or more than 1 , and "at least 80%" means 80% or more than 80%. When, in this specification, a range is given as " (a first number) to (a second number)" or "(a first number) - (a second number)", this means a range whose lower limit is the first number and whose upper limit is the second number. For example, "from 50 to 1000C" or "50-1000C" means a range whose lower limit is 5O0C, and whose upper limit is 1000C. The numbers given herein should be construed with the latitude appropriate to their context and expression; for example, each number is subject to variation which depends on the accuracy with which it can be measured by methods conventionally used by those skilled in the art. The terms plural, multiple, plurality and multiplicity are used herein to denote two or more than two items. The term "metal" is used herein to include a single metal, a mixture of two or more metals, and an alloy of two or more metals.

(d) forms part of a golf club head and is a straight and/or curved rail which lies in a plane which is parallel to (including which is the same as) a plane which (i) contains two of the three principal axes of the golf club head [the x-axis (front to back), the y-axis (shaft to toe), and the z-axis (sole to crown)] of the golf club head, and (ii) is at right angles to the other axis or is inclined at an angle (e.g. 5 to 85°, or 10 to 80°, or 10 to 45°, or 45 to 80°) to the other axis, for example in a plane which is parallel to (including which is the same as) the yz plane and is at a selected angle to the shaft of the golf club, e.g. an angle which is 75 to 90°, or 90° to 105°, e.g. substantially 90°; or which lies in a plane which is inclined to all three axes;

(e) is part of the shaft of a golf club, e.g. part of the main shaft itself, or a rail or post extending from the main shaft;

(f) is a cavity, which may for example have a cross section which is the same throughout its depth or which increases or decreases regularly or irregularly, e.g. comprises ridges which cooperate with the weight member, e.g. circumferential ridges; or

(g) a post, which may for example have a cross section which is the same throughout its height or which increases or decreases regularly or irregularly, e.g. comprises ridges which cooperate with the weight member, e.g. circumferential ridges.

(6) There is a plurality of location members.

The golf club heads of the invention can optionally comprise a cover plate which is secured to the back of the golf club head and which at least partially covers the weight member or members. The cover plate can bear against the weight member, or against one or more of a plurality of weight members, to assist in ensuring that the weight members do not come loose during use. The cover plate is preferably secured to the remainder of the golf club head by a securing means such that the cover plate cannot be easily removed during the course of a round of golf, in order to comply with the USGA rules.

Heat-recoverable metals (also known as shape memory metals) and superelastic metals are well known, and are used in a wide variety of applications, including for example structural and medical applications. Shape memory alloys generally exhibit a shape memory effect as a result of their ability to transform between martensitic and austenitic phases as the results of a change in temperature. Further information is available is available in the article by L. M. Schetky in Scientific American, Volume 241 , pages 68 to 76 (1979) entitled Shape Memory Alloys. Many shape memory metals are nickel-titanium based alloys, which may include additional elements to change the transformation temperature or strength characteristics. Shape memory metals based on other alloys are also known. Reference may be made for example to U.S. Patent Nos. 3,753,700, 4,337,090, 4,565,589, 4,770,725, 4,144,104, 4,146,392 and 4,166,739, the entire disclosures of which are incorporated herein by reference. Description of the Drawings

Referring now to the drawings, in which the same reference numerals are used to denote the same or similar components, Figures 1-6 show convertible weight members 2 comprising a gripping member 21 which is composed of heat-recoverable metal, which is in the form of a split ring (Figures 1 and 2), a split tube (Figures 3 and 4) or a coiled wire (Figures 5 and 6). In Figures 1-4, the weight member also includes a second component 22 composed of a metal which is not heat-recoverable. Figure 7-14 show golf club heads 3 comprising a body portion 31 and one or more location members 1. In Figures 7-10, 13 and 14, weight member(s) 2 is(are) fitted to the location member(s). In Figures 11-12, there are a plurality of location members in the form of cavities into one or more of which weight members as shown in Figures 3-6 can be fitted while they are cold and in the first shape. The weight members are then converted into the second shape as they warm to room temperature and thus become secured within the cavities. In Figures 15 and 16, a weight member 2 fits within a heat- recoverable location member having a C-shaped cross-section. Under the first set of conditions, the location member 1 clamps down on the center section of the weight member 2 and fixes it in place. Under the second set of conditions, the cross-section of the location member opens sufficiently to allow the weight member to slide to a different position.
