Abstract

A marker post formed of a resilient materiel which is normally bendable without breaking, with the resilient material arranged in a triangular cross shape with internal webs therein to impart sufficient rigidity to the marker post to enable the marker post to be driven into most soils with the internal webs coacting to provide a restoring force to enable the marker post under many field conditions to return to a normally straight condition.

Claims

1. A hollow resilient one piece marker post for indicating the presence of an object comprising:

an elongated member, said elongated member including a first panel having a first edge and a second edge, a second panel having a first edge and a second edge and a third panel having a first edge and a second edge, said elongated member further including a first radiused corner member having a first edge and a second edge, a second radiused corner member having a first edge and a second edge and a third radiused corner member having a first edge and a second edge, said first panel first edge integrally joined with said first radiused corner first edge and said second panel second edge integrally joined with second edge of said first radiused corner, said second panel first edge integrally joined with said second radiused corner first edge, said third panel second edge integrally joined with second edge of said second radiused corner and said third panel first edge integrally joined with said third radiused corner member first edge, said third radiused corner member second edge integrally formed with said second edge of said first panel to thereby form a triangular shaped cross section; and

a first integral web extending from said first panel to said second panel said first integral web spaced inwardly away from said first radiused corner to create a gap therebetween, a second integral web extending from said second panel to said third panel said second integral web spaced inwardly away from said second radiused corner to create a gap therebetween and a third integral web extending from said third panel to said first panel said third integral web spaced inwardly away from said third radiused corner to create a gap therebetween with said webs cooperating to provide resiliency to said marker post so that when said marker post is bent by an object, the marker post can return to its original condition when the object is removed.

2. The resilient one piece marker post of claim 1 wherein the elongated member is made of polycarbonate.

3. The resilient one-piece marker post of claim 1 wherein the elongated member includes a cap for covering a first end of said elongated member to prevent rain from entering into said elongated member.

4. The resilient one-piece marker post of claim 1 wherein the elongated member has sufficient stiffness to permit the marker post to be driven into a top layer of soil.

5. The marker post of claim 1 wherein the elongated hollow member includes a cap to cover an end of said hollow elongated member.
