Turning now to the drawings and, more particularly to
The pole body 12 includes a proximate end portion 13 as defined by a tapered end portion 15 having generally conical walls 16 for insertion into a support medium such as, for example, the earth and media associated thereto such as snow or the ground. Embodiments include those wherein the tapered end portion 15 includes a pointed tip 18. As shown in
The pole body 12 includes a distal end portion 14. Embodiments include those wherein the upper surface 14a of the distal end portion 14 of the pole body 12 is generally flat. Alternative embodiments include those wherein the upper surface 14a of the distal end portion 14 of the pole body 12 is formed with a rough surface such as may be left by a saw or machine cut. Embodiments further include those wherein the pole body 12 is approximately 3 to 4 feet long and one-quarter to one-half inch in diameter.
Embodiments and alternatives are provided having an impact cap 20 disposed at the distal end portion 14 of the pole body 12 thereby being placed at the end opposite the tapered end portion 15. The impact cap 20 includes a cylindrical wall 22. The impact cap 20 and cylindrical wall 22 define an internal cavity 24 which internal cavity 24 further includes an access opening 26 into which the distal end portion 14 of the pole body 12 projects. The impact cap 20 includes a substantially planar surface opposing the access opening 26. Embodiments include those wherein the access opening 26 provides access to the internal cavity 24 of the cylindrical walls 22. A nail-head surface 28, comprising a generally flat end panel, is formed integrally with the cylindrical wall 22 to ultimately form the impact cap 20. Some embodiments of the nail-head surface 28 have a substantially planar surface. As desired, the diameter of the internal cavity 24 is selected to be slightly larger than the diameter of the pole body 12 such that the distal end portion 14 of the pole body 12 fits snugly within the internal cavity 24. As seen in the Figures, in some embodiments, the impact cap 20 is fitted over the distal end portion 14 of the pole body 12 in a snug, friction-fitting manner. In some embodiments, the planar surface of the impact cap 20 opposing the access opening 26 is in substantial contact with the upper surface 14a of the distal end portion 14 of the pole body 12 when the impact cap 20 is fitted over the distal end portion 14 of the pole body 12. The impact cap 20 is generally undeformable and generally unbreakable thereby providing durability and facilitating repeated and continued use of the caution pole 10 year after year. The generally undeformable and generally unbreakable impact cap 20 allows the user to drive the caution pole 10 into the ground by applying force directly to the impact cap 20. Therefore, it will further be readily understood that the material composition of the impact cap 20 relates directly to mechanical function of driving the caution pole 10 into the ground and not merely to ornamentation.
As seen in
It should be understood that while the present application discusses embodiments in terms of being hammer-driven, any driving implement may be used to drive the present caution pole 10 into the support medium such as snow or ground. Embodiments are provided wherein any driving implement will suffice to apply force to the impact cap 20 sufficient to drive the pole 12 into the support medium. Alternatives include those wherein a driving implement such as, for example, a blunt instrument to include a hammer, achieves the best force distribution over the nail-head surface 28. Other embodiments and alternatives are provided wherein other objects may be used to provide force sufficient to drive the pole 12 into the support medium as needed or as desired by a user.
In operation, a user may take a hammer or other driving implement to the impact cap 20 to drive the caution pole 10 into the support medium. In some embodiments, usually one or two blows are sufficient to drive the caution pole 10 sufficiently into the snow or into the ground. The high visibility surface enhances the ability for others to see the caution pole 10 and thus become alert to a hazard. The impact cap 20 provides the ability to drive the caution pole 10 into the snow or ground to the extent that it will typically not blow over or become unstable under adverse circumstances. Further, in some embodiments, the impact cap 20 prevents the upper surface 14a of the distal end portion 14 of the pole body 12 from splintering, mushrooming or deforming upon receiving force from a driving implement.
Embodiments include those wherein the caution pole 10 includes a clip 30 disposed on the pole body 12 as shown in
With reference to
Embodiments include those wherein the base 36 is attached to the pole body 12 by attachment means such as, for example, friction-fit, glue, adhesive, dowel, rivet, pin, screw, bolt, fastener, or any other suitable means for attaching the base 36 to the pole body 12.
With reference back to
With reference to
Embodiments include those wherein the clip 30 is comprised of substantially metal material. Alternatively, the clip 30 is comprised of any material suitable for securing the attachment 44 such as, for example, plastic or rubber. As seen in the Figures, embodiments include those wherein the caution pole 10 consists of no more than three parts: the pole body 12, the impact cap 20, and the clip 30.
By the above, the embodiments and alternatives provide an effective low-cost, lightweight caution pole with the ability to be driven by hammer or other driving implement and the ability to secure an attachment such as barricade or caution tape.
It will therefore be readily understood by those persons skilled in the art that the present embodiments and alternatives are susceptible of a broad utility and application. While the present embodiments and alternatives are described in all currently foreseeable embodiments, there may be other, unforeseeable embodiments, alternatives and adaptations of the present embodiments and alternatives, as well as variations, modifications and equivalent arrangements, that do not depart from the substance or scope of the present invention. The foregoing disclosure is not intended or to be construed to limit the present embodiments and alternatives or otherwise to exclude such other embodiments, adaptations, variations, modifications and equivalent arrangements, the present embodiments and alternatives being limited only by the description provided herein, the claims appended hereto and the equivalents thereof.
