Abstract

A playing field layout device includes an alignment guide having a plurality of lines marked thereon. A stake is inserted in the alignment guide, and a cord has one end attached to the stake. The cord has a plurality of marks thereon. The playing field may be, for example, volleyball, croquet, or badminton and may be laid out by aligning the cord over relevant lines and marking distances at predetermined locations indicated by the marks. The layout device may then be removed from the playing field so that it does not interfere with the participants.

Claims

1. A method for laying out a playing field comprising:

placing an alignment guide at a predetermined position on the playing field, the alignment guide including a plurality of lines at predetermined angles with respect to each other;

placing one end of a flexible element at an intersection of said plurality of lines, the flexible element having a plurality of marks at predetermined positions therealong;

aligning the flexible element over one of the lines and marking a position on the field at a location corresponding to a first of said plurality of marks on the flexible element; and

moving said flexible element to a position over another of said lines and marking a position on the field corresponding to a position of another of the plurality of marks.

2. The method according to claim 1, comprising removing the alignment guide and flexible element from the field after the positions on the field are marked.

3. The method according to claim 1, comprising inserting a stake into the intersection of the lines on the alignment guide and connecting the one end of the flexible element to the stake.

4. The method according to claim 3, wherein the alignment guide is supported on a supporting surface and the stake is inserted through the alignment guide into the supporting surface.

5. The method according to claim 1, wherein the intersection of the lines is at the center of the alignment guide.

6. The method according to claim 1, wherein one of the plurality of lines and one of the plurality of marks determines the location of a net post.

7. The method according to claim 1, wherein at least one of the plurality of lines and at least one the plurality of marks determines a corner of the playing field.

8. The method according to claim 1, wherein the playing field is a volleyball court.

9. The method according to claim 1, wherein the playing field is a croquet court.

10. The method according to claim 1, wherein the playing field is a badminton court.

11. A device for laying out a playing field comprising:

an alignment guide having a plurality of lines at predetermined angles relative to each other;

a stake capable of being inserted into the alignment guide at an intersection of said lines; and

a flexible element having one end attached to said stake and a plurality of marks at predetermined distances from said one end.

12. The device for laying out a playing field according to claim 11, wherein said intersection of said lines are at a the center of said alignment guide.

13. The device for laying out a playing field according to claim 11, wherein each of the plurality of marks is painted on said flexible element.

14. The device for laying out a playing field according to claim 11, wherein each of the plurality of marks is a knot on said flexible element.

15. The device for laying out a playing field according to claim 11, wherein each of the plurality of marks is a clip on said flexible element.

16. The device for laying out a playing field according to claim 11, wherein each of the plurality of marks is a tape on said flexible element.

17. The device for laying out a playing field according to claim 11, wherein said stake is an eye bolt.
