Abstract

A wood type golf club formed of a shaft and head assembly, the head assembly including a hollow main body portion and an insert coupled thereto along the majority of its periphery by a dovetail to preclude lateral and downward movement of the insert with respect to the main body portion, the main body portion having a ramp extending outwardly from its face with the adjacent face of the insert having a recess positioned to receive the ramp thereby precluding the movement of the insert upwardly away from the main body portion and further including an adhesive coupling the insert to the main body portion.

Claims

1. A wood type golf club formed of a shaft and head assembly, the head assembly including a hollow main body portion having an insert-receiving exterior face having a periphery and an insert for stroking a golf ball, the insert having an interior face, an exterior face and a periphery turnaround, the insert being coupled to the main body portion along the majority of the periphery of the exterior face of the main body portion by a dovetail to preclude material and downward movement of the insert with respect of the main body portion, the exterior face of the main body portion having a ramp extending outwardly therefrom, the interior face of the insert having, within the periphery of the insert, a recess positioned to receive the ramp thereby precluding the movement of the insert upwardly away from the main body portion and further including an adhesive coupling the insert to the main body portion.

2. A golf clubhead assembly formed of a main body portion with ah insert-receiving exterior face and an insert for striking a golf ball, said insert having an interior face, said assembly further including mechanical means to couple to the main body portion to the insert, the mechanical means including a mating peripheral dovetail arrangement between said main body portion and said insert and a wedge having an angled outwardly projecting face located within the boundaries of the peripheral dovetail arrangement and further including a recess for matingly receiving said projecting face.

3. The assembly as set forth in claim 2 wherein the wedge is centrally located on the exterior face of the main body portion.

4. The assembly as set forth in claim 3 wherein the recess is located in the interior face of the insert facing the wedge for the receipt thereof.

5. The assembly as set forth in claim 4 wherein the wedge has an essentially horizontal lower face positioned in contact with an essentially horizontal lower face in the recess.

6. The assembly as set forth in claim 5 wherein the insert has peripheral edges and the main body portion has peripheral edges and further including mating dovetails around the majority of the peripheral edges of the insert and the main body portion.

7. The assembly as set forth in claim 6 wherein the insert includes a plurality of vertical recesses for receiving an adhesive.

8. The assembly as set forth in claim 7 wherein the assembly is a wood type head with a hollow main body portion.
