Abstract

A marking device for marking the location of underground utility lines including an indicating member having at least one substantially planar surface and a positioning member rigidly secured to the indicating member that includes a stake member oriented perpendicularly with respect to the substantially planar surface having a plurality of stabilizing members extending therefrom and oriented at an angle of between thirty and sixty (30°, 60°) degrees thereto. The stabilizing members are constructed from a material having sufficient resilience to allow each stabilizing member to flex while the stake member is inserted into the earth. The indicating member includes indicia indicating at east one type of utility and indicia indicating a direction of travel with respect to the indicating member.

Claims

1. A utility marking device comprising:

a substantially disk shaped indicating member having at least one substantially planar surface, said indicating member including integrally formed utility indicia indicating at least one type of utility and integrally formed direction indicia indicating a direction of travel with respect to said indicating member, said indicating member being at least three times broader in a first direction than said indicating member is thick in a second direction, said second direction being orthogonal to said first direction; and

a positioning member rigidly secured to said indicating member and extending from a center of a side surface of said indicating member, said positioning member including a conically shaped stake member, oriented perpendicularly with respect to said substantially planar surface, said stake member having six stabilizing members extending therefrom that each have a curve along the entire length thereof having a radius of curvature of about eight inches, said stabilizing members each curving away from a tip of said stake member, said stabilizing members being constructed from a material having sufficient resilience to allow each said stabilizing member to flex while said stake member is inserted into soil located above a utility line.
