Abstract

A golf putter having a CORIAN putterhead [10] and a handle [110] affixed thereto. The putterhead is a three layer [20, 30, 40 ] hollow, [31], ear-shaped methacrylate sandwich fixedly encapsulating a variably sized lead shot weight filler [60, 70] in the hollow. Putting alignment inlays [50] are affixed in the top surface. The sandwich has a flat putting face [80] and a curvo-linear shaped body [90] the top edge of which is slanted [120]. The different colored CORIAN layers and alignment indicators add to the aesthetics of the putterhead. The CORIAN putting face [80] reduces the tendency of the golf ball to skid when it is contacted. The sandwich is made by adhering a hollowed [31] middle layer [30] to a flat end layer [20], inserting the lead shot [60] and resin filler [70], closing with a flat end layer [40 ] and shaping. The sandwich is then provided with the alignment inlays [50 ], final shaped [120], finished to a high luster and provided with a handle [110]. The layers [20, 30, 40] may each be made up of multiple layers [FIGS. 16, 17].

Claims

1. A golf putter comprising:

a methacrylate putterhead adapted to receive a shaft comprising;

a first layer of methacrylate material that is the sole of the putterhead;

a second layer of methacrylate material that is the body of the putterhead;

a third layer of methacrylate material that is the top of the putter head;

weight means that are an integral part of the putterhead;

means for attaching the weight means to the methacrylate material;

means for attaching the layers of methacrylate material together;

a first cross-sectional side of the putterhead that comprises the face; and

a second cross-sectional side of the putterhead that comprises the back, and

a shaft affixed to the putterhead as a golf handle for the putter.

2. A methacrylate putterhead apparatus comprising:

a first layer of methacrylate material that is the sole of the putterhead;

a second layer of methacrylate material that is the body of the putterhead;

a third layer of methacrylate material that is the top of the putterhead;

weight means that are an integral part of the putterhead;

means for attaching the weight means to the methacrylate material;

means for attaching the layers of methacrylate material together;

a first linear cross-sectional side of the putterhead that comprises the face; and

a second curvo-linear cross-sectional side of the putterhead that comprises the back.

3. A methacrylate putterhead apparatus according to claim 2 further comprising;

at least one alignment inlay attached to the putterhead.

4. A methacrylate putterhead apparatus according to claim 2 wherein the means for attaching the weight means to the methacrylate material include:

means for placing the weights inside the methacrylate putterhead; and

resin filler for adhering the weights and methacrylate material together.

5. A methacrylate putterhead apparatus according to claim 4 wherein the means for placing the weights inside the methacrylate putterhead is provided by the body layer of methacrylate material being hollow and the contiguous sole and top layers of methacrylate material being solid.

6. A methacrylate putterhead apparatus according to claim 2 wherein the top edge of the curvo-linear side of the putterhead is inwardly slanted.

7. A methacrylate putterhead apparatus according to claim 2 wherein the weight means that are an integral part of the putterhead are lead shots, the weight of the putter being a function of the size and number of lead shots.

8. A methacrylate putterhead apparatus according to claim 2 further comprising means for attaching a shaft of a golf putterhead handle to the methacrylate putterhead.

9. A methacrylate putterhead apparatus according to claim 8 wherein the means for attaching the shaft of the golf putterhead handle to the methacrylate putterhead include means for inserting the shaft into the methacrylate putterhead at an angle which determines the lie angle of the putterhead.

10. A methacrylate putterhead apparatus according to claim 2 wherein the face of the putterhead has a loft angle.

11. A methacrylate putterhead apparatus according to claim 2 wherein the face provided by the methacrylate material when contacted with golf ball reduces the amount of skid on the ball.

12. A methacrylate putterhead apparatus according to claim 2 wherein the putterhead is made for a right-handed golfer.

13. A methacrylate putterhead apparatus according to claim 2 wherein the putterhead is made for a left-handed golfer.

14. A methacrylate putterhead apparatus according to claim 2 wherein the first layer of methacrylate material that is the sole of the putterhead comprises of a number of thinner multiply laminated layers of methacrylate material.

15. A methacrylate putterhead apparatus according to claim 14 wherein the first layer that is the sole of the putterhead comprises of two thinner laminated layers of methacrylate material.

16. A methacrylate putterhead apparatus according to claim 2 wherein the third layer of methacrylate material that is the bottom of the putterhead comprises of a number of thinner multiply laminated layers of methacrylate material.

17. A methacrylate putterhead apparatus according to claim 16 wherein the third layer that is the bottom of the putterhead comprises of two thinner laminated layers of methacrylate material.

18. A methacrylate putterhead apparatus according to claim 2 wherein the second layer of methacrylate material that is the body of the putterhead comprises of a number of thinner multiply laminated layers of methacrylate material.

19. A methacrylate putterhead apparatus according to claim 18 wherein the second layer of methacrylate material that is the body of the putterhead comprises of four thinner laminated layers of methacrylate material.

20. A methacrylate putterhead apparatus comprising:

a first layer of methacrylate material that is the sole of the putterhead;

a second layer of methacrylate material that is the body of the putterhead;

a third layer of methacrylate material that is the top of the putterhead;

weight means that are an integral part of the putterhead;

means for attaching the weight means to the methacrylate material;

means for attaching the layers of methacrylate material together;

a first cross-sectional side of the putterhead that comprises the face; and

a second cross-sectional side of the putterhead that comprises the back.
