Patent ID: 8439401

Claim:
A caution pole comprising: a generally elongate pole body; a generally undeformable and generally unbreakable impact cap; a clip disposed on the pole body; the pole body having a proximate end portion and a distal end portion, the proximate end portion formed with a tapered end portion for insertion into a support medium, the distal end portion formed to have a generally planar upper surface and further formed in a generally cylindrical profile to receive the impact cap; the impact cap having a flat nail head surface; the impact cap formed to have a generally cylindrical body having an access opening correspondingly formed to receive the distal end portion of the pole body on one end thereof, and a substantially planar surface opposing the access opening, the impact cap being fitted over the distal end portion of the pole body; and upon receiving impact force from a driving implement, the impact cap distributing the impact force evenly over the pole, thereby achieving enhanced efficiency and reduced force transmission sequentially from the driving implement, to the flat nail head surface of the impact cap, to the planar surface of the impact cap, and to the distal end portion of the pole body during reversible and removable insertion of the caution pole into a support medium, wherein the clip includes a clip proximate end portion and a clip distal end portion, the clip having a base disposed at the clip proximate end portion and an arm extending from the base, wherein the base is formed to wrap around the pole body and the shape of the base is chosen from the group cylinder, cube, hexagonal cylinder, octagonal cylinder, and barrel and wherein the clip comprises the only protrusion on the sides of the pole body.
