Abstract

A tool for laying out a pattern of a measured size and orienting the pattern with respect to an exterior point of reference is disclosed. A cord having a plurality of anchoring points spaced along its length is arrayed to form the pattern. A direction finding device orients the pattern formed by the cord to a point of reference exterior to the pattern. Anchoring devices anchor each anchoring point of the cord to a surface so that the cord is held to the surface in the shape of the pattern. The cord is attached to a spool which stows the cord, anchoring devices, and direction finding device when not deployed.

Claims

1. An apparatus for laying out a pattern of a measured size and orienting the pattern with respect to an exterior point of reference, said apparatus comprising:

a cord having a measured length for forming the pattern, said cord having a plurality of anchoring points spaced along its length;

a direction finding device attached to said cord, said direction finding device for orienting the pattern formed by said cord to a point of reference exterior to the pattern; and

a plurality of anchoring devices, each of said plurality of anchoring devices for securing one of the plurality of anchoring points to the surface.

2. The apparatus of claim 1, further comprising a spool attached to said cord for receiving said cord wound thereon and for stowing said plurality of anchoring devices and said direction finding device.

3. The apparatus of claim 2, wherein the pattern is a rectangle and wherein each of the plurality of loops is positioned at one corner of the rectangle.

4. The apparatus of claim 3, wherein the plurality of anchoring points comprises a first loop, a second loop, a third loop, a fourth loop, a fifth loop and a sixth loop, the first loop and the second loop partitioning the cord into a long length, the third, forth, fifth and sixth loops partitioning the cord into four short lengths wherein each of the short lengths may be arrayed to form a side of the square and the long length may be arrayed to form a diagonal of the rectangle.

5. The apparatus of claim 4, wherein the direction finding device is fixed to the long length adjacent to the second loop.

6. The apparatus of claim 4, wherein the spool is fixed to a short length adjacent to the sixth loop.

7. The apparatus of claim 4, wherein the orienting means comprises means for orienting the pattern to magnetic north.

8. The apparatus of claim 1, further comprising a tag attached to said cord adjacent to each of the attachment points to identifying the attachment point.

9. The apparatus of claim 1, wherein each of the plurality of anchoring devices is a stake for anchoring the cord to the ground.

10. The apparatus of claim 9, wherein the non-magnetic material is selected from the group consisting of aluminum, brass, titanium, plastic, composite, and wood.

11. The apparatus of claim 1, wherein each of the plurality of anchoring devices is made from a non-magnetic material.

12. The apparatus of claim 1, wherein said direction finding device comprises a magnetic compass.
