Abstract

An improved synthetic golf tee which has a substantially uniform transverse cross sectional wall thickness along the entire length thereof from a ball supporting end to a tapered end. The tee can be manufactured by either injection molding or machining and is the same weight or is slightly heavier in weight than a conventional wooden tee. A central bore extends through a major portion of the golf tee.

Claims

1. A hollow synthetic golf tee comprising:

a ball supporting end having an annular surface which is contoured for supporting a golf ball;

a tapered end for facilitating insertion of at least a portion of the synthetic tee into a ground surface; and

an intermediate portion interconnecting said ball supporting end and said tapered end with one another to form a contiguous monolithic golf tee;

wherein a central bore extends completely through said ball supporting end, said intermediate portion and a portion of said tapered ends;

said ball supporting end tapers into a sharp circular linear edge which provides a perimeter point contact for solely Engaging with and supporting a golf ball, during use, to minimize a contact area between a golf ball and the golf tee when the golf ball is supported thereon.

2. A hollow synthetic tee according to claim 1, wherein at least said intermediate portion has a substantially uniform transverse cross sectional wall thickness along the entire length thereof.

3. A hollow synthetic tee according to claim 1, wherein both said ball supporting end and said intermediate portion have a substantially uniform transverse cross sectional wall thickness along the entire length thereof.

4. A hollow synthetic tee according to claim 3, wherein said substantially uniform transverse cross sectional wall thickness of said synthetic golf tee is between about 0.053 and 0.075 inches.

5. A hollow synthetic tee according to claim 3, wherein each of said ball supporting end, said intermediate portion and said tapered end has a substantially uniform transverse cross sectional wall thickness along the entire length thereof.

6. A hollow synthetic tee according to claim 1, wherein said central bore has a diameter of approximately 0.050 inches to 0.093 inches.

7. A hollow synthetic tee according to claim 1, wherein said golf tee is manufactured from one of a thermoplastic polymer and an acetal resin.

8. A hollow synthetic tee according to claim 1, wherein said taper of said ball supporting end has substantially the same angle as the taper of said tapered end.

9. A hollow synthetic tee according to claim 8, wherein said taper of both said ball supporting end and of said tapered end ranges between about 10 to about 60 degrees.

10. A hollow synthetic tee according to claim 1 in combination with a tee carrying device, said tee carrying device comprises an elongate cylindrical body section which has a diameter sufficiently larger than said central bore of said golf tee so that an interference fit is achieved between said cylindrical body section and said central bore whereby upon engagement between said central bore and said cylindrical body section, said synthetic tee is releasably retained by the tee carrying device.

11. The combination according to claim 10, wherein said tee carrying device includes a head section which is attached to said cylindrical body section, and said head section includes a mechanism for attaching said tee carrying device to a desired object.

12. The combination according to claim 10, wherein said tee carrying device further includes a tail section which is tapered to facilitate insertion of said tee carrying device into said central bore of said golf tee.

13. A hollow synthetic tee according to claim 1 in combination with a light stick, said light stick is accommodated within said central bore of said synthetic tee to facilitate playing of golf at night time.

14. A hollow synthetic golf tee according to claim 1, wherein said sharp circular linear edge has a circumference smaller than a maximum circumference of exterior surface of said ball supporting end and smaller than a maximum circumference of an inner surface of said ball supporting end.

15. A method of manufacturing a synthetic golf tee comprising the steps of:

providing a ball supporting end with an annular surface which is contoured for supporting a golf ball;

providing said synthetic golf tee with a tapered end for facilitating insertion of at least a portion of the synthetic tee into a ground surface;

providing an intermediate portion to interconnect said ball supporting end and said tapered end with one another to form a contiguous monolithic golf tee; and

forming a central bore completely through said ball supporting end, said intermediate portion and a portion of said tapered end;

forming said annular surface of said ball supporting end with a circular linear edge which provides a perimeter point contact for solely engaging with and supporting a golf ball during use to minimize the area contact between a golf ball and the golf tee when the golf ball is supported on the golf tee;

inserting said golf tee in a ground surface; and

supporting said golf ball solely by said circular linear edge to minimize the contact area between a golf ball and the golf tee.

16. A method according to claim 15, further comprising the step of providing at least said intermediate portion with a substantially uniform transverse cross sectional wall thickness along the entire length thereof.

17. A method according to claim 15, further comprising the step of providing both said ball supporting end and said intermediate portion with a substantially uniform transverse cross sectional wall thickness along the entire length thereof.

18. A method according to claim 17, further comprising the step of using a transverse cross sectional wall thickness of between about 0.053 and 0.075 inches.

19. A method according to claim 15, further comprising the step of providing each of said ball supporting end, said intermediate portion and said tapered end with a substantially uniform transverse cross sectional wall thickness along the entire length thereof.

20. A hollow synthetic golf tee in combination with a golf ball, said synthetic golf tee comprising:

a ball supporting end having an annular surface which is contoured for supporting a golf ball;

a tapered end for facilitating insertion of at least a portion of the synthetic tee into a ground surface; and

an intermediate portion interconnecting said ball supporting end and said tapered end with one another to form a contiguous monolithic golf tee;

wherein a central bore extends completely through said ball supporting end, said intermediate portion and a major portion of said tapered end;

each of said ball supporting end, said intermediate portion and said tapered end has a substantially uniform transverse cross sectional wall thickness along the entire length thereof;

said ball supporting end tapers into a sharp circular linear edge which provides a perimeter point contact for solely engaging with and supporting a golf ball, during use, to minimize a contact area between a golf ball and the golf tee when the golf ball is supported thereon; and

said golf ball being supported solely by said sharp circular linear edge to minimize contact between said golf ball and said golf tee.
