Abstract

Multiple molded polymeric units are joined together by side mounted fastening mechanisms. Each polymeric unit is molded as an integral structure with a smooth contoured top surface and a bottom grid like portion. Each polymeric unit has two side walls containing slots for mounting the fastening mechanism. A third side wall joining the two walls is a raised rolled edge higher than the top surface. The polymeric unit has a receptacle for receipt of a golf cup and a water drain hole. A simulated grass layer overlays the smooth top surface of the joined polymeric units.

Description

BRIEF DESCRIPTION OF THE DRAWINGS

The invention can be best understood by those having ordinary skill in the art by reference to the following detailed description when considered in conjunction with the accompanying drawings in which:

Claims

1. A portable golf putting training green comprising

2. The portable golf putting training green according to claim 1 wherein the top surface is contoured to simulate a rolling putting green surface.

3. The portable golf putting training green according to claim 1 wherein a water drain hole passes through the polymeric unit.

4. The portable golf putting training green according to claim 1 wherein a chipping platform comprising a polymeric unit having a smooth planar top surface integral with a supporting grid and a layer of simulated grass over the smooth planar top surface is spaced apart from the portable golf putting training green.

5. The portable golf putting training green according to claim 1 wherein the fastening mechanism is a cam operated S-hook within the first and second side walls of one polymeric unit engaging a complimentary plate in the first and second side walls of an adjacent polymeric unit, the cam adapted to be turned by an allen wrench.

6. The portable golf putting training green according to claim 1 wherein the polymeric units are made by a blow molding process.

7. The portable golf putting training green according to claim 1 wherein the polymeric units are made by an injection molding process.

8. The portable golf putting training green according to claim 1 wherein the polymeric units are made by a compression molding process.

9. The portable golf putting training green according to claim 1 wherein the grid structure consists of multiple joined six sided elements open at a bottom and closed at a top by the smooth top surface.

10. A portable golf putting training green comprising:

11. The portable golf putting training green according to claim 10 wherein the smooth top surface is contoured to simulate a natural putting green surface.

12. The portable golf putting training green according to claim 10 wherein the grid like bottom surface is in the shape of multiple joined hexagons.

13. The portable golf putting training green according to claim 10 wherein the simulated grass layer is a close cropped multi-fiber rug.

14. The portable golf putting training green according to claim 10 wherein the simulated grass layer is synthetic turf.

15. The portable golf putting training green according to claim 1 wherein there are four polymeric units joined together and covered with simulated grass.

16. The portable golf putting training green according to claim 15 wherein the simulated grass is synthetic turf.

17. The portable golf putting training green according to claim 15 wherein the simulated grass is a closely cropped rug.

18. The portable golf putting training green according to claim 1 wherein the polymeric units are made by a low pressure blow molding process.

19. The portable golf putting training green according to claim 1 wherein the polymeric units are made by rotational molding.

20. The portable golf putting training green according to claim 1 wherein the polymeric units are made by structural foam injection molding.
