GOLF CLUB AND GOLF CLUB HEAD WITH INTERCHANGEABLE BODY COMPONENT
An iron type golf club head includes a club head having a first body component defining a striking face, and a second body component releasably secured to the first body component with a fastener. The second body component defines at least a perimeter portion of a rear face of the club head body and may define substantially an entire rear face of the club head body.
This invention relates generally to golf clubs and golf club heads, and, in particular, to golf clubs and golf club heads having an interchangeable body component.
BACKGROUND OF THE INVENTIONGolfers tend to be sensitive to the “feel” of a golf club. The “feel” of a golf club comprises the combination of various component parts of the club and various features associated with the club that produce the sensory sensations experienced by the player when a ball is swung at and/or struck. Club weight, weight distribution, swing weight, aerodynamics, swing speed, and the like all may affect the “feel” of the club as it swings and strikes a ball. “Feel” also has been found to be related to the sound produced when a club head strikes a ball to send the ball in motion. If a club head makes an unpleasant, undesirable, or surprising sound at impact, a user may flinch, give up on his/her swing, decelerate the swing, lose his/her grip, and/or not completely follow-through on the swing, thereby affecting distance, direction, and/or other performance aspects of the swing and the resulting ball motion. User anticipation of this unpleasant, undesirable, or surprising sound can affect a swing even before the ball is hit.
The performance of a golf club can vary based on various factors, including weight distribution about the head, which affects the location of the center of gravity of the golf club head. When the center of gravity is positioned behind the point of engagement on the contact surface, the golf ball follows a generally straight route. When the center of gravity is spaced to a side of the point of engagement, however, the golf ball may fly in an unintended direction and/or may follow a route that curves left or right, ball flights that often are referred to as “pulls,” “pushes,” “draws,” “fades,” “hooks,” or “slices”. Similarly, when the center of gravity is spaced above or below the point of engagement, the flight of the golf ball may exhibit more boring or climbing trajectories, respectively.
Accordingly, club heads may be formed with various configurations to provide different performance characteristics and “feels.” Additionally, club heads often have a cavity formed in its rear surface into which different weights can be placed to alter the performance characteristics and “feel” of the club.
It would be desirable to provide a golf club and golf club head that reduces or overcomes some or all of the difficulties inherent in prior known devices. Particular objects and advantages will be apparent to those skilled in the art, that is, those who are knowledgeable or experienced in this field of technology, in view of the following disclosure of the invention and detailed description of certain embodiments.

These and additional features and advantages disclosed here will be further understood from the following detailed disclosure of certain embodiments.
The figures referred to above are not drawn necessarily to scale, should be understood to provide a representation of particular embodiments of the invention, and are merely conceptual in nature and illustrative of the principles involved. Some features of the golf club and golf club head having an interchangeable body component depicted in the drawings have been enlarged or distorted relative to others to facilitate explanation and understanding. The same reference numbers are used in the drawings for similar or identical components and features shown in various alternative embodiments. Golf clubs and golf club heads having an interchangeable body component as disclosed herein would have configurations and components determined, in part, by the intended application and environment in which they are used.
DETAILED DESCRIPTION OF CERTAIN PREFERRED EMBODIMENTSAn embodiment of a golf club 10 is shown in
As seen in
Body member 18 of golf club head 14 may be constructed from a wide variety of different materials, including materials conventionally known and used in the art, such as steel, titanium, aluminum, magnesium, nickel, tungsten, alloys of these metals, graphite, polymers, fiber-reinforced materials, or composites, or combinations thereof. Other suitable materials will become readily apparent to those skilled in the art, given the benefit of this disclosure. It is to be appreciated that first body component 34 and second body component 40 may be formed of the same or different material.
First body component 34 and second body component 40 are removably secured to one another with a fastener arrangement 46, as illustrated in
In the embodiment illustrated in
Another embodiment of a fastener 46 used to secure first body component 34 and second body component 40 to one another is illustrated in
Another embodiment of club head 14 is illustrated in
As noted above, because second body component 40 is removably secured to first body component 34, second body component 40 can advantageously, easily, and quickly be replaced with a different second body component having one or more different characteristics than those of the initial second body component 40. Specifically, second body component 40 can be replaced with a new second body component having a different shape or geometry than that of initial second body component 40. Through the use of such interchangeable body components, golf club head 14 can be modified to produce a club head with different performance characteristics.
As seen in the embodiments illustrated in
An alternative embodiment of a second body component 60 is illustrated in
Another alternative embodiment of a second body component 62 is illustrated in
A further alternative embodiment of a second body component 68 is illustrated in
Yet a further alternative embodiment of a second body component 76 is illustrated in
Another embodiment of a second body component 78 is illustrated in
Thus it can be seen that any number of alternative second body components can be substituted for second body component 40. Accordingly, a user can have a variety of different second body components that can be substituted for one another for a variety of reasons. For example, a second body component can be selected based on playing conditions expected to be encountered (e.g., different course conditions, different weather conditions, different wind conditions, etc.), the type of golf ball being used, and the skill or ability of the golfer. As a user improves, they may adapt a different playing style, and being able to replace the second body component of the club head allows them to modify their club without purchasing an entirely new club. It is to be appreciated that all aspects of the geometry or mass properties of club head 14 can be modified through the use of the interchangeable body component including, but not limited to, the club head's shape, weight, weight distribution, bounce angle, center of gravity, moment of inertia, material of which it is formed, and appearance, which can alter the center of gravity, moment of inertia, and/or other “feel” characteristics of club head 14.
Such interchangeable body components, that is, additional second body components can be provided for each of the different clubs a golfer uses, allowing significant flexibility for the golfer. Alternatively, if desired, by exchanging first body components on a given second body component (optionally with the hosel element formed with the second body component), the user may alter the loft angle of the club (e.g., to change a wedge from a 48 degree wedge to a 52 degree wedge).
An alternative embodiment of a fastener 80 for golf club head 14 is illustrated in
Another alternative embodiment of a fastener 94 is illustrated in
As illustrated herein, it can be seen that there are many alternative engagement structures and fastener arrangements available for securing first and second body components 34, 40 together. As an additional example, dovetail or other types of joints may be provided to help securely hold the first and second body components 34, 40 together. Other suitable engagement and fastener arrangements will become readily apparent to those skilled in the art, given the benefit of this disclosure.
An alternative embodiment is shown in
Further, it is to be appreciated that the mortise slots 116 could be formed on second body component 40 with the corresponding tenons 118 being formed on first body component 34. In other embodiments, the mortise slots and tenons could be mixed, with some mortise slots 116 formed on first body component 34 and others formed on second body component 40, and corresponding tenons 118 being formed on both first and second body component 34, 40.
The mating of first and second alignment members 112, 114 serves to align and register first body component 34 and second body component 40 with respect to one another, helping to ensure a rigid and accurate connection between them.
Another embodiment is shown in
Thus, while there have been shown, described, and pointed out fundamental novel features of various embodiments, it will be understood that various omissions, substitutions, and changes in the form and details of the devices illustrated, and in their operation, may be made by those skilled in the art without departing from the spirit and scope of the invention. For example, it is expressly intended that all combinations of those elements and/or steps which perform substantially the same function, in substantially the same way, to achieve the same results are within the scope of the invention. Substitutions of elements from one described embodiment to another are also fully intended and contemplated. It is the intention, therefore, to be limited only as indicated by the scope of the claims appended hereto.
