Abstract

Generally, provided is an insert for usage on an outer surface of a sporting apparatus (e.g., a golf club). The insert includes a securing member that protrudes from surface of the insert. The securing member may include a stem and a head, wherein the stem functions to couple the head to a face of the securing member. The head of the securing member functions to prevent the insert from becoming dislodged or separated from the outer surface of the sporting apparatus during usage.

Claims (30)

1. A golf club head, comprising:

a top portion;

a striking face coupled to the top portion;

a sole portion coupled to the striking face, the sole portion including an inner surface and an outer surface, the sole portion further defining an aperture extending therethrough;

a uni-directional, non-rotatable insert including a face and a securing member, the securing member comprising a stem portion and a head portion, the securing member configured to contact the inner surface for securing the insert to the sole portion, the face including a rim that surrounds the face; and

an adhesive layer located between the outer surface and the face, the adhesive layer covering the entirety of the face within the rim and including an opening through which the stem passes, the adhesive layer having a thickness greater than a height of the rim.

2. The golf club head of claim 1 , wherein the securing member includes a gap that extends from a tip of the head along a direction of the stem axis, the gap subdividing the head portion into a first head portion and a second head portion.

3. The golf club head of claim 2 , wherein the aperture has an aperture diameter, the stem portion having a stem diameter wherein the aperture diameter is substantially equivalent to the stem diameter such that the stem portion is configured to extend through the aperture.

4. The golf club head of claim 3 , wherein the head portion includes a engagement surface proximal the stem portion and having an engagement diameter, the head portion further includes a leading surface distal the stem portion and having a leading diameter.

5. The golf club head of claim 4 , wherein the engagement diameter is greater than the aperture diameter and the leading diameter no greater than the aperture diameter.

6. The golf club head of claim 5 , wherein the head portion further includes a tapered wall which couples the leading surface and the engagement surface.

7. The golf club head of claim 5 , wherein when the head portion is inserted into the aperture, the first head portion and the second head portion flexes toward one another until the engagement surface contacts the inner surface of the sole portion.

8. The golf club head of claim 1 , wherein a thickness of the aperture is substantially equal to the difference of the thicknesses of the stem and the adhesive layer.

9. The golf club head of claim 1 , wherein a transition region proximal the stem portion and head portion includes a step.

10. A golf club head, comprising:

a top portion;

a striking face coupled to the top portion;

a sole portion coupled to the striking face, the sole portion including a recessed portion defining an aperture, the recessed portion having an inner wall and outer wall; and

a uni-directional, non-rotatable insert including:

a face including a rim that surrounds the face,

an adhering layer having a first surface for contacting and adhering to the face and having a second surface opposite the first surface for contacting and adhering to the recessed portion of the sole portion,

a securing member adjacent the second surface of the adhering layer, the securing member configured to be insertably locked into the sole portion, the securing member comprising a stern portion and a head portion, and

an adhesive layer located between the outer wall and the face, the adhesive layer covering the entirety of the face within the rim and including an opening through which the stern passes, the adhesive layer having a thickness greater than a height of the rim.

11. The golf club head of claim 10 , wherein the securing member comprises a stem and a head, the stem positioned between the head and the face.

12. The golf club head of claim 11 , wherein a maximum diameter of the head is greater than a maximum diameter of the stem.

13. The golf club head of claim 12 , wherein a maximum diameter of the head is greater than a maximum diameter of the aperture, and a maximum diameter of the stem is no greater than a maximum diameter of the aperture.

14. The golf club head of claim 13 , further comprising a bore extending through the head.

15. The golf club head of claim 14 , wherein the bore further extends through the stem.

16. The golf club head of claim 15 , wherein the bore is configured to allow the head to temporarily flex from an uncompressed state to a compressed state when the head is inserted into the aperture.

17. The golf club head of claim 16 , wherein the bore is further configured to allow the head to return to the uncompressed state when a surface of the head defining the maximum diameter engages the inner wall.
