Three-piece golf club iron head structure

Abstract

This invention provides a three-piece golf iron head structure, comprising a hitting unit made of a first material, a body unit made of a second material, a cover unit made of a third material, and a connecting module. The connecting module uses at least two fasteners to lock the body unit to the hitting unit. A first adhesive unit is provided on a second adhesive portion on one side of the body unit and is attached to a first adhesive portion of the hitting unit. A second adhesive unit is provided on a third adhesive portion on the other side of the body unit and is attached to the cover unit. This allows for the combination of the hitting unit, body unit, and cover unit made of different materials through locking and adhesive methods, combining the advantages of each material. Furthermore, the assembly process eliminates the need for welding, thus improving structural stability and durability.

Claims

1. A three-piece assembled golf iron head structure, comprising: a hitting unit formed of a first material, the hitting unit including a hitting face, a set portion, and a handle portion, wherein the hitting face has a striking surface on one side facing a first direction, and the set portion is formed on the other side opposite the striking surface, and the set portion has a first adhesive portion protruding from its periphery along the first direction, and the handle portion protrudes from the side of either the hitting face or the set portion, wherein... The striking unit has at least two locking holes protruding within the space formed by the first adhesive portion surrounding the assembly portion; a body unit is formed of a second material, the body unit has a second adhesive portion along its periphery on one side corresponding to the striking unit, and a third adhesive portion along its periphery on the other side, the body unit is assembled with the second adhesive portion at the first adhesive portion, and the body unit has a limiting through hole formed at the corresponding locking hole positions, and a counterweight unit is provided between the limiting through holes to adjust its center of gravity; a cover unit is formed of a third material, the periphery of one side of the cover unit is assembled with the third adhesive portion of the body unit; and a connecting module has at least two locking fasteners, a first adhesive unit and a second adhesive unit, the first adhesive unit and the second adhesive unit being arranged around the periphery of the locking fasteners; The locking fasteners are respectively inserted through the limiting through holes and locked into the locking holes, so that the cover unit abuts against the counterweight unit; the first adhesive unit is disposed between the first adhesive part and the second adhesive part, and the second adhesive unit is disposed between the periphery of the cover unit of the third adhesive part.

2. The three-piece golf iron head structure as described in claim 1, further comprising, wherein the first adhesive portion has a first annular bottom wall and an adjacent first annular protruding wall, wherein, The first annular convex wall is formed by protruding from the end adjacent to the bottom wall of the first ring along the first direction.

3. The three-piece golf club head structure as described in claim 1, further comprising the limiting through holes protruding radially to form a limiting portion.

4. The three-piece golf iron head structure as described in claim 2, further comprising the second adhesive portion having a second annular protrusion and an adjacent second annular bottom wall, wherein the second annular protrusion is disposed opposite to the first annular bottom wall, and the second annular bottom wall is disposed opposite to the first annular protrusion.

5. The three-piece golf iron head structure as described in claim 4, further comprising the first adhesive unit being disposed at least between the first annular convex wall and the second annular bottom wall or between the first annular bottom wall and the second annular convex wall.

6. The three-piece golf iron head structure as described in claim 1, further wherein the first material of the striking unit, the second material of the body unit, and the third material of the cover unit are different from each other.

7. The three-piece golf iron head structure as described in claim 1, further comprising a plurality of grooves on the striking face of the striking surface.

8. The three-piece golf iron head structure as described in claim 1, further comprising that the first material of the striking unit and the second material of the body unit are metallic, while the third material of the cover unit is non-metallic.

9. The three-piece golf iron head structure as described in claim 1, further wherein the striking unit and the body unit are each integrally formed.
