A golf club head (10) of the wood variety is constructed of a titanium ball striking plate (16), a composite central housing part (18) and a back housing part (22) assembled into a unitary configuration. The central housing part and back housing part are constructed of a graphite composite with carbon fibers. One or more weights are fixedly secured within the back housing part (22) to provide a center of gravity for the head (10) located just rearwardly of the plate (16) and below the centerline between the top and bottom surfaces of the central housing part (18).
1. A golf club head of the wood variety, comprising:
a metal ball striking plate constructed of titanium having a rear formed surface;
a central housing part to which a hosel and shaft is connected and including a surface contoured to fittingly engage with the striking plate formed surface;
a back housing part having an edge wall secured to a portion of the central housing part facing in a direction opposite to that of the striking plate; and
means for securing the striking plate to the central housing part.

1. Field of the Invention
The present invention relates generally to a golf club, and, more particularly to the construction of the head of a golf club of the so-called wood variety as opposed to a club of the iron variety.
2. Description of Related Art
A full set of golf clubs typically includes three general categories or varieties of clubs commonly referred to as “woods”, “irons” and a “putter”. Much earlier this terminology was adopted because the striking head of the longer clubs was made of wood whereas the striking head of the shorter clubs was made of iron, and a putter was a special form of an iron club. More recently, although the terminology of a “wood” is still used for the longer club category, the head of the club may be found to be made of metal alone or in combination with a non-wood material (e.g., various plastics).
Moreover, wood clubs come in different lengths and striking face slopes varying from the least sloping face and longest club (a “driver”) which is typically used to strike a ball positioned on the top of a tee stuck into the ground, to shorter and greater sloping striking faces considered for striking a ball located on a ground surface. The present invention will be described primarily in connection with a driver head construction for ease of presentation, although the head construction may be advantageously applied to other wood clubs of the shorter length and greater sloped striking faces.
In the practice of the present invention there is provided a golf club head of the wood category constructed of multiple parts assembled to form a unitary club head including a high-density metal ball striking plate and the remainder of relatively low-density nonmetal parts with an overall head center of gravity located lower and more forwardly than would be achieved by a single material head of either solid or hollow construction.
These and other objects of the present invention will become more readily apparent upon reading the following detailed description and upon reference to the attached drawings in which:

Moreover, the flange 48 and the flange 26 on the ball striking plate 16 are so dimensioned and formed that the plate can be fitted onto the central housing part 18 such that the two flanges interfit and mate with one another (
When the plate is assembled onto the central housing part as just described, the opening 28 in the plate flange fits into a slot 52 on the outer surface of the cylindrical member 46. Preferably the plate 16 is secured to the central housing portion flange by three metal pegs 54, 56 and 58 extending through appropriately formed openings in the two flanges 26 and 48, one centered on the top wall and two spaced apart on the bottom wall (
Similarly, a further flange 60 unitary with the central housing encircles the rear opening 42 conforming to the opening geometry and contiguous with the inner cavity of central housing and terminating at an outwardly extending flange wall 62 that faces rearwardly of the central housing (
For the ensuing description of the back housing part 22, reference is made to
Although other materials may be advantageously employed, in a practical construction of the invention both the central housing part and back housing part were molded from a graphite composite including carbon fibers and having a weight of approximately 4.0 ounces where the maximum overall distance from the rear wall to the front wall was 4.75 inches and the external height was 2.25 inches. The titanium ball striking plate was constructed of a plate having a thickness of 0.125 inches and weighed 4.5 ounces.
On assembly, the bushing 20 is mounted within an opening 66 in the upper surface of the cylindrical member 46 and the outer surfaces of the housing parts and striking plate are finished to a smooth flat surface. Finally, a protective coating is applied to the outer surface of the housing parts.
One or more weights 68 are secured to the bottom wall of the back housing cavity (
Although the present invention has been described in connection with a preferred embodiment, it is to be understood that those skilled in the appertaining art may make modifications that come within the spirit of the invention as disclosed and within the ambit of the appended claims.
