Abstract
A golf club head includes: a head body that includes a cavity; a weight that is detachably attached to the cavity; and a cover that is openably and closably attached to the head body and that covers at least a part of the cavity when the cover is in a closed state. The weight is attached to the cavity in a state where the weight is slidingly movable in the cavity. In the closed state, the cover applies a pressing force to the weight. The weight may be fixed to the cavity by a static frictional force increased by the pressing force. The cavity may form a slide groove.
Claims20
A golf club head comprising:
- a head body having an interior and an exterior which includes a groove shaped cavity;
- a weight that is detachably attached to the cavity;
- and
- a cover that is attached to the head body, is in a closed state when the cover covers at least a part of the cavity and is alternatively in an open state,
- wherein
- the weight is attached to the cavity in a state where the weight is slidingly movable in the cavity,
- in the closed state, the cover inner surface directly or indirectly abuts against the weight to apply a pressing force to the weight,
- a first end portion of the cover is fixed to the head body with a first cover attaching member,
- a second end portion of the cover is fixed to the head body with a second cover attaching member,
- the weight includes a first abutment portion that is a first side surface of the weight and a second abutment portion that is a second side surface of the weight,
- the cavity includes a first slide portion on a first side surface which abuts the first abutment portion and a second slide portion on a second side surface which abuts the second abutment portion,
- in the slide movement of the weight, the first and second abutment portions slide on the first and second slide portions so that the weight slides within the cavity,
- the weight has a shape that allows the weight to slidingly move within the cavity,
- the cavity includes a first tapered portion in which a distance between the first side surface and the second side surface gradually decreases toward the head body interior,
- the weight includes a second tapered portion in which a distance between the first side surface and the second side surface gradually decreases, and
- the second tapered portion is fitted into the first tapered portion so that the weight is fitted within the cavity.
A golf club head comprising:
- a head body that includes a groove shaped cavity;
- a weight that is detachably attached to the cavity;
- and
- a cover that is attached to the head body, is in a closed state when the cover covers at least a part of the cavity and is alternatively in an open state,
- wherein
- the weight is attached to the cavity in a state where the weight is slidingly movable in the cavity,
- in the closed state, the cover inner surface applies a pressing force directly or indirectly to the weight,
- a first end portion of the cover is fixed to the head body with a first cover attaching member,
- a second end portion of the cover is fixed to the head body with a second cover attaching member,
- the weight includes an abutment portion,
- the cavity includes a slide portion that abuts the abutment portion at only three or more contact points,
- in the slide movement of the weight, the abutment portion slides on the slide portion so that the weight slides within the cavity, and
- the weight has a shape that includes corners or projections on the abutment portion or the slide portion has projections such that the weight abutment portion contacts the cavity slide portion at a total of three or more contact points.
A golf club head comprising:
- a head body that includes a groove shaped cavity;
- a weight that is detachably attached to the cavity;
- and
- a cover that is attached to the head body, is in a closed state when the cover covers at least a part of the cavity and is alternatively in an open state,
- wherein
- the weight is attached to the cavity in a state where the weight is slidingly movable in the cavity,
- the cover inner surface includes a cover engaging shape that engages with the weight at a plurality of positions in a path of the slide movement of the weight,
- the weight includes a weight engaging shape that engages with the cover engaging shape when the cover is in the closed state,
- the cover engaging shape includes a plurality of cover recess portions or cover projection portions formed at a plurality of positions in the path of the slide movement, and
- the weight engaging shape includes a weight projection portion that complementarily engages with the cover recess portions, or a weight recess portion that complementarily engages with the cover projection portions.
