Abstract

The pitching rubber comprises a block of hard rubber having a lateral flange at each longitudinal end thereof. Each flange is secured to the block of rubber and has a section which extends outwardly therefrom in a manner to lie against a surface underlying the rubber block. Each flange has a bore therein for receiving a spike therethrough, the spike being pounded into the ground to secure the pitching rubber in place. To remove the pitching rubber, the spikes are simply pried out of the ground in known manner.

Claims

1. A portable pitching rubber for use in playing ball comprising a block of hard rubber having mounting flanges engaged thereto, a section of each flange extending longitudinally from and lying against a surface underlying, the rubber block, said block being approximately 3/4 inch high, and having a width between 3 inches and 7 inches and a length between 16 inches and 26 inches.

2. The pitching rubber of claim 1 wherein each flange is made of metal.

3. The pitching rubber of claim 2 wherein each flange has first, second and third planar sections.

4. The pitching rubber of claim 3 wherein a first section of said flange extends longitudinally from longitudinal ends of said rubber block and has a bore therethrough.

5. The pitching rubber of claim 4 wherein said bore is sized and configured to receive a spike therethrough.

6. The pitching rubber of claim 5 wherein a second section of flange is perpendicular to the first section, and extends upwardly along the longitudinal end of said rubber block to approximately half the height of said block.

7. The pitching rubber of claim 6 wherein said second section of each flange tapers upwardly.

8. The pitching rubber of claim 7 wherein a third section of said flange is perpendicular to said second section and extends into said rubber block a predetermined distance.

9. The pitching rubber of claim 8 wherein said third section of said flange has a centered, relatively large opening therein.

10. The pitching rubber of claim 9 wherein said opening is filled with the hard rubber of the block.

11. The pitching rubber of claim 10 wherein said opening extends to and cuts into a top surface of said second flange section.

12. The pitching rubber of claim 11 wherein the width and length of the block are 4 inches and 18 inches, respectively.

13. The pitching rubber of claim 11 wherein the width and length of the block are 6 inches and 24 inches, respectively.

14. The pitching rubber of claim 11 wherein said flange third section extends approximately 21/2 inches into said rubber block.

15. The pitching rubber of claim 14 wherein said flange third section is approximately 2 inches wide.

16. The pitching rubber of claim 15 wherein said flange is centered along the width of said block.

17. The pitching rubber of claim 16 wherein said flange first section is approximately 4 inches long.

18. A portable pitching rubber for use in playing ball comprising a rectangular block of hard rubber having a flange mounted to each longitudinal end thereof, each flange including three sections, a first planar section extending outwardly of said block and being coplanar with one rectangular surface thereof, a second planar section perpendicular to said first section and rising along said longitudinal end of said block and a third planar section perpendicular to said second section and extending into said block, each first flange section having a bore therethrough, each third flange section having an opening therein, and each second section extending from said first section to said third section.
