Abstract:
1. A highway marker device for marking the location of an object located adjacent to a highway, the device comprising: (a) a coil spring having a first end and a second end, wherein the coil spring is comprised of a plurality of windings around a spring axis; (b) a marker post connected with the first end of the coil spring, wherein the marker post has a post axis and wherein the post axis is substantially perpendicular to the spring axis; and (c) a mounting mechanism for connecting the device with the object such that the coil spring is substantially restrained from bending about the spring axis, wherein the mounting mechanism is comprised of a primary mounting mechanism and a secondary mounting mechanism and wherein the secondary mounting mechanism is axially spaced along the spring axis relative to the primary mounting mechanism so that the primary mounting mechanism and the secondary mounting mechanism together substantially restrain the coil spring from bending about the spring axis.
