Golf club having removable weight
A golf club head includes a club head body and a weight member that is secured to the body. The weight member is constructed to utilize lateral forces to couple to the head body to minimize the structure required to retain the weight member, and the weight member is preferably constructed so that it has a low profile.
1. A golf club head, comprising:
a club head body including a face defining a ball-striking surface, a sole, a crown, and a skirt, wherein said sole extends aftward from a lower edge of said face, wherein said crown extends aftward from an upper edge of said face, and wherein said skirt extends between said sole and said crown around a perimeter of said club head body;
a weight mount disposed on said club head body, wherein said weight mount includes an aperture defined by an outer surface of said club head body; and
a weight member comprising a weight body, at least one lock tab, and a locking mechanism,
wherein said weight body includes a cavity configured to receive at least a portion of said locking mechanism and at least a portion of said at least one lock tab,
wherein said weight body includes a sidewall having at least one aperture,
wherein said locking mechanism is rotatably coupled to said weight body,
wherein said locking mechanism has a substantially elliptical shape and includes a cam surface on an outer periphery,
wherein said at least one lock tab includes a first end proximate said cam surface and a second end opposite said first end,
wherein in a locked configuration a major axis of said locking mechanism is aligned with said at least one lock tab such that said at least one lock tab protrudes from said at least one aperture in said sidewall and secures said weight member within said weight mount, and
wherein in an unlocked configuration a minor axis of said locking mechanism is aligned with said at least one lock tab such that said at least one lock tab is retracted inward toward said cavity of said weight body and said weight member is removable from said weight mount.
2. The golf club head of claim 1 , wherein said first end of said at least one lock tab is attached to a spring to bias said at least one lock tab toward said cam surface.
3. The golf club head of claim 2 , wherein said spring is mounted to said weight body.
4. The golf club head of claim 2 , wherein said spring surrounds said cam surface and said locking mechanism is configured to rotated within said spring.
5. The golf club head of claim 1 , wherein said at least one lock tab is biased toward said cam surface by magnetic force in said unlocked configuration.
6. The golf club head of claim 5 , wherein said locking mechanism includes at least one magnetic insert at said cam surface in line with said minor axis.
7. The golf club head of claim 5 , wherein said at least one lock tab includes a magnetic insert at said first end.
8. The golf club head of claim 1 , wherein said at least one lock tab is tapered such that said first end has a dimension greater than said second end.
9. The golf club head of claim 1 , wherein said locking mechanism has at least one flat portion along said cam surface.
10. The golf club head of claim 1 , wherein said locking mechanism includes a tool engagement feature configured to receive a tool to rotate said locking mechanism relative to said weight body.
11. A weight member, comprising:
a weight body having an internal cavity, said weight body including a sidewall having an aperture;
a locking mechanism rotatably coupled to said weight body and at least partially enclosed within said internal cavity, said locking mechanism having a cam surface on an outer periphery; and
a lock tab at least partially enclosed within said internal cavity, said lock tab having a first end proximate said cam surface and a second end opposite said first end,
wherein in a locked configuration said lock tab protrudes from said aperture in said sidewall, and
wherein in an unlocked configuration said lock tab is retracted inward toward said internal cavity.
12. The weight member of claim 11 , wherein said lock tab is biased toward said cam surface by a spring.
13. The weight member of claim 11 , wherein said lock tab is biased toward said cam surface by magnetic force.
14. The weight member of claim 11 , wherein said locking mechanism has a substantially elliptical shape.
15. The weight member of claim 11 , wherein said weight body includes at least one indicium, wherein said locking mechanism includes at least one indicium, and wherein alignment of said at least one indicium of said weight body and said at least one indicium of said locking mechanism corresponds to one of said locked configuration and said unlocked configuration.
16. The weight member of claim 11 , wherein said locking mechanism has a magnetic insert and said lock tab is made of a ferrous material.
17. The weight member of claim 11 , wherein said weight body has a substantially cylindrical shape.
18. The weight member of claim 11 , wherein said locking mechanism includes a tool engagement feature configured to receive a tool to rotate said locking mechanism relative to said weight body.
19. The weight member of claim 11 , wherein said lock tab is tapered such that said first end has a dimension greater than said second end.
20. The weight member of claim 19 , wherein said aperture in said sidewall is tapered.
