Abstract

According to various aspects, exemplary embodiments are disclosed of golf putter heads having customizable centers of gravity that are adjustable in three dimensions. Also disclosed are exemplary embodiments of methods of adjusting a center of gravity of a golf putter head.

Claims

1. A golf putter head comprising:

a hollow body portion having a top surface; and

a plurality of weights configured to be added at a plurality of different available locations along the top surface of the hollow body portion, thereby providing a plurality of different options for adding weight to the golf putter head for adjusting a center of gravity of the golf putter head in three dimensions.

2. The golf putter head of claim 1, wherein:

the top surface of the hollow body portion includes a plurality of openings that define the different available locations along the top surface; and

the weights are configured to be inserted into the openings in the top surface of the golf putter head.

3. The golf putter head of claim 1, wherein:

the openings in the top surface of the hollow body portion are internally threaded; and

the weights include outer threaded surfaces such that the weights are threadingly engageable within the internally threaded openings.

4. The golf putter head of claim 2, wherein:

the top surface of the hollow body portion includes first, second, and third recessed portions respectively located adjacent or along a heel portion, a middle portion, and a toe portion of the golf putter head; and

the openings in the top surface are disposed within the first, second, and third recessed portions.

5. The golf putter head of claim 4, further comprising first, second, and third caps configured to positioned over the respective first, second, and third recessed portions, and wherein each of the first, second, and third recessed portions includes two or more of the openings equally and circumferentially spaced apart from each other within the corresponding recessed portion.

6. The golf putter head of claim 1, wherein:

the golf putter head includes a plurality of dials slidably and rotatably supported within a hollow interior of the hollow body portion, the dials including a plurality of openings that define the different available locations along the top surface of the hollow body portion; and

the weights are configured to be inserted into the openings in the dials.

7. The golf putter head of claim 6, wherein:

the golf putter head includes a striking surface and a bracket having a first portion attached internally along or to an inner surface of a portion of the golf putter head that defines the striking surface;

the bracket includes a plurality of elongate members that extend outwardly from the first portion; and

the dials are rotatingly and slidably coupled to corresponding ones of the elongate members.

8. The golf putter head of claim 7, wherein:

each elongate member includes a slot extending along a portion of a length of the elongate member; and

the dials are rotatable and slidable along the slots of the corresponding elongate members.

9. The golf putter head of claim 7, wherein:

the openings of the dials are internally threaded;

the weights include outer threaded surfaces such that the weights are threadingly engageable within the internally threaded openings of the dials; and

each dial includes two or more of the internally threaded openings circumferentially spaced apart from each other.

10. The golf putter head of claim 7, wherein:

the first portion of the bracket has a shape and size complementary to a shape and size of the striking surface; and

the elongate members extend outwardly from the first portion such that an acute angle is defined therebetween.

11. The golf putter head of claim 1, wherein:

a plurality of inserts disposed at different locations along an inside top surface of the hollow body, the inserts include openings that define the different available locations along the top surface of the hollow body; and

the weights are configured to be inserted into the openings of the inserts.

12. The golf putter head of claim 1, wherein at least two of the plurality of weights have different weights;

and/or wherein;

the different available locations along the top surface of the hollow body portion are defined by a plurality of internally threaded openings; and

the weights include outer threaded surfaces such that the weights are threadingly engageable within the internally threaded openings.

13. A golf putter comprising the golf putter head of claim 1 coupled to a shaft, wherein the golf putter is configured to use spring force for putting a golf ball.

14. A method of adjusting a center of gravity of a hollow golf putter head in three dimensions, the method comprising adding one or more of a plurality of weights to the hollow golf putter head at one or more of a plurality of different available locations along a top surface of the hollow golf putter head.

15. The method of claim 14, wherein adding one or more of a plurality of weights comprises adding at least two weights to the golf putter head at two different locations along the top surface of the hollow golf putter head.

16. The method of claim 14, wherein at least two of the weights have different weights, and wherein adding one or more of a plurality of weights comprises adding the at least two weights having different weights to the hollow golf putter at two different locations along the top surface of the hollow golf putter head.

17. The method of claim 14, wherein:

the top surface of the hollow golf putter head includes a plurality of openings that define the different available locations along the top surface of the hollow golf putter head;

the weights are configured to be inserted into the openings in the top surface of the golf putter head; and

adding one or more of a plurality of weights comprises inserting one or more of the weights into a corresponding one or more of the openings in the top surface of the golf putter head.

18. The method of claim 17, wherein:

the openings in the top surface of the golf putter head are internally threaded;

the weights include outer surfaces that are threaded; and

inserting one or more of the weights into a corresponding one or more of the openings comprises rotating and threadingly engaging the one or more weights with the corresponding one or more openings.

19. The method of claim 14, wherein:

the golf putter head includes a plurality of dials slidably and rotatably supported within a hollow interior of the hollow golf putter head, dials including a plurality of openings that define the different available locations along the top surface of the hollow golf putter head; and

adding one or more of a plurality of weights comprises;

adding one or more weights to one or more of the openings of one or more of the dials; and

sliding and/or rotating the one or more of the dials before and/or after adding the one or more weights to the one or more openings of the one or more dials.

20. The method of claim 14, wherein:

the golf putter head includes a plurality of inserts disposed at different locations along an inside top surface of the golf putter head, the inserts include openings that define the different available locations along the top surface of the hollow golf putter head; and

adding one or more of a plurality of weights comprises inserting the one or more weights into a corresponding one or more of the openings of the inserts.
