摘要:
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.
