Delineating pole having an anchoring base and spring cartridge for snow based applications
An anchoring base for a delineating pole using the reconfiguration of protruding resilient mechanical members to facilitate insertion and resist the subsequent extraction force on the pole. The mechanical members extend outwards relative to the insertion rod longitudinal axis, and bend or configure upon insertion of the anchoring base, into a first position that facilitates insertion while impeding and resisting axial extraction forces, and upon subsequent rotation of the anchoring base, the mechanical members bend or reconfigure into a second position such that the extraction resistance force is significantly reduced. The anchoring base design may be used in conjunction with a spring cartridge having a plurality of interlocking members forming a rigid mechanical structure during rotation.
1. An anchoring base for a delineator pole for snow based applications comprising an insertion rod having a longitudinal axis, said insertion rod including a plurality of resilient mechanical members extending outwards relative to said insertion rod longitudinal axis, wherein said plurality of resilient mechanical members comprises a plurality of bristles or bristle tufts, said plurality of resilient mechanical members bending or configuring upon insertion of said anchoring base, into a first position or configuration that facilitates insertion while impeding and resisting axial extraction forces, and upon subsequent rotation of said anchoring base, said plurality of mechanical members bending or reconfiguring into a second position or configuration reducing said anchoring base extraction resistance force.
2. The anchoring base of claim 1 including:
a flange; and
a connector portion having a first end attached to said insertion rod and a second end attached to said flange.
3. The anchoring base of claim 2 wherein said flange, insertion rod, and said connector may be integrally formed.
4. The anchoring base of claim 1 including having said plurality of resilient mechanical members arranged in an upward direction at an angle less than ninety degrees from said longitudinal axis.
5. The anchoring base of claim 2 wherein said connector includes said plurality of resilient mechanical members.
6. A delineator pole having a pole portion and an anchoring base for securing said pole portion, said anchoring base comprising a protruding resilient member that flexibly compresses in response to insertion forces and opposes removal forces that would result in an unintended extraction, wherein said protruding resilient member includes bristles or bristle tufts.
7. The delineator pole of claim 6 including having said protruding resilient member extend approximately radially from said anchoring base longitudinal axis.
8. The delineator pole of claim 6 including having said anchoring base removably attached to said delineator pole.
9. The delineator pole of claim 8 wherein said anchoring base includes:
a flange at a first end of said anchoring base for receiving and aligning said pole portion, and for providing a depth guide to ensure proper placement of said anchoring base during insertion; and
an insertion rod at a second end of said anchoring base from which said protruding resilient member extends.
10. The delineator pole of claim 9 wherein said protruding resilient member is aligned by, attached to, or secured by, said insertion rod.
11. The delineator pole of claim 6 wherein said protruding resilient member includes a brush structure comprising plastic or metal material.
12. The delineator pole of claim 6 wherein said protruding resilient member comprises a bendable material capable of compressing into a first configuration upon insertion into ice or a dense snow pack, said first configuration having a retention strength to oppose extraction.
13. The delineator pole of claim 7 wherein, prior to insertion, said protruding resilient member is angled upwards relative to said anchoring base longitudinal axis in a direction towards said pole portion.
