Abstract:
1. A Marker Pole consisting of: no more than two parts; each of the no more than two parts being formed from materials of substantially constant physical composition throughout their structure and further comprising a comparison of the physical composition of the first part being substantially plastic material and the physical composition of the second part being substantially metal material; the first part being a generally elongate pole body having substantially no protrusions on the sides thereof; the pole body having a penetrating end and a distal end, the penetrating end formed with a tapered tip for insertion into a support medium, the distal end being formed to have a generally planar upper surface and further formed in a generally cylindrical profile to receive the second part being a generally undeformable and unbreakable impact cap; the impact cap having a flat nail head structure; the impact cap being formed to have a generally cylindrical body having an access opening correspondingly formed to receive the distal end of the pole body on one end thereof, and a substantially planar surface opposing the access opening, the planar surface being in substantial contact with the upper surface of the distal end of the pole body when the impact cap is fitted over the distal end; 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 structure of the impact cap, to the planar surface of the impact cap, and to the distal end of the pole body during reversible and removable insertion of the marker pole into the support medium when using an impact producing tool; and, upon reversible and removable insertion of the marker pole into the support medium, at least a portion of the pole body being disposed outside of the support medium.
