Weighted golf club
A weighted golf club is disclosed herein. More specifically, a golf club head includes a chassis with a heel opening and a toe opening defined therein. A heel weight member is disposed within the heel opening and a toe weight member is disposed within the toe opening. The heel weight member and the toe weight member are securely mechanically attached to the chassis by a fastener.
1. A golf club head comprising:
a chassis formed of a first material having a first density, said chassis including a heel having a heel opening, a toe opposite said heel having a toe opening, a topline, a sole opposite said topline, a hosel, a rear wall and a striking face coupled to the heel, toe, topline and sole;
a heel weight member disposed within the heel opening, said heel weight member being formed of a second material having a second density greater than the first density, wherein said heel weight member comprises a heel mass portion and a heel extension portion, the heel weight member being inserted into the heel opening at an angle an of less than +/−30° relative to a ground plane G when the golf club head is held in a normal address position;
a toe weight member disposed within the toe opening, said toe weight member being formed of a third material having a third density greater than the first density, wherein said toe weight member comprises a toe mass portion and a toe extension portion, the toe weight member being inserted into the toe opening at an angle α t of less than +/−30° relative to the ground plane G when the golf club head is held in the normal address position;
a housing disposed within a center opening interposed between said heel opening and said toe opening,
wherein said center opening is connected to said heel opening by a center heel opening and said center opening is connected to said toe opening by a center toe opening,
wherein said heel extension portion extends through said center heel opening into said center opening and said toe extension portion extends through said center toe opening into said center opening, and
wherein a fastener passes through each of said housing, said heel extension portion, and said toe extension portion, and mates with a fastener receiving hole defined in said chassis within said center opening to mechanically couple said heel weight member and said toe weight member with said chassis.
2. The golf club head of claim 1 , wherein the angle α h is less than +/−10° relative to the ground plane G when the golf club head is held in the normal address position and the angle α t is less than +/−10° relative to the ground plane G when the golf club head is held in the normal address position.
3. The golf club head of claim 2 , wherein said heel mass portion includes a heel notch and said chassis includes a heel tab that mates with said heel notch, and wherein said toe mass portion includes a toe notch and said chassis includes a toe tab that mates with said toe notch.
4. The golf club head of claim 3 , wherein first complimentary grooves are defined in said heel notch and said heel tab and second complimentary grooves are defined in said toe notch and said toe tab.
5. The golf club head of claim 1 , wherein said heel mass portion and said toe mass portion are configured such that the golf club head has a preselected overall mass.
6. A golf club head comprising:
a chassis including a heel, a toe opposite said heel, a topline, a sole opposite said topline, a hosel, a striking face, and a rear wall opposite said striking face;
a center opening in said rear wall;
a toe opening in said toe that is configured to receive a toe weight member, wherein said toe weight member has a first mass of between about 40 grams and 100 grams and includes a toe mass portion having a toe mass shape corresponding to a toe opening shape, and a toe extension portion, the toe weight member being inserted into the toe opening at an angle α t of less than +/−30° relative to a ground plane G when the golf club head is held in a normal address position and extending into said center opening;
a heel opening in said heel that is configured to receive a heel weight member, wherein said heel weight member has a second mass of between about 10 grams to 25 grams and includes a heel mass portion having a heel mass shape corresponding to a heel opening shape, and a heel extension portion extending into the heel opening at an angle α h of less than +/−30° relative to the ground plane G when the golf head is held in the normal address position and extending into said center opening;
a housing disposed within said center opening, interposed between said heel opening and said toe opening,
wherein said center opening is connected to said heel opening by a center heel opening and said center opening is connected to said toe opening by a center toe opening,
wherein said heel extension portion extends through said center heel opening into said center opening and said toe extension portion extends through said center toe opening into said center opening,
and
a fastener mating with a fastener receiving hole within said center opening to mechanically couple said toe weight member and said heel weight member with said chassis.
7. The golf club head of claim 6 , wherein said housing comprises a first recess having a first recess shape corresponding to said heel extension portion and a second recess having a second recess shape corresponding to said toe extension portion.
8. The golf club head of claim 6 , wherein said toe mass portion includes a recess and said toe opening includes a projection, and wherein said recess and said projection constitute a dovetail joint.
