Abstract
Abstract A moveable device used for delineating traffic lanes, adapted to be selectively placed into permanent dug holes for channeling vehicular traffic. The device comprises a bendable tubular post of polyethylene fastened to a rigid conical base. The base has a downward circular anchoring extension which can be inserted into a dug hole. The base has a very low above-ground profile and can be impacted by high speed vehicles without being damaged or pulled off the ground.

Claims Analysis
Total Claims: 8
Claim 1
Independent Claim
119 words
A readily removable device for delineating traffic lanes or the like which comprises: an elongated tubular post made of lightweight pliable material having a cylindrical, threaded lower end; a substantially conical base having at its apex a shallow well threaded and dimensioned to hold the lower end of the said post secured therein; extending downward from the bottom center of said base and integrally therewith, a solid anchoring stud having a rounded lower end; and in the ground surface, at least one sleeved dug hole shaped and dimensioned to fit closely around said stud; said anchoring stud being free from vertical restraint in relation to said dug hole other than the combined weight of said post base and stud.
Claim 2
Dependent Claim
119 words
A readily removable device for delineating traffic lanes or the like which comprises: an elongated tubular post made of lightweight pliable material having a cylindrical, threaded lower end; a substantially conical base having at its apex a shallow well threaded and dimensioned to hold the lower end of the said post secured therein; extending downward from the bottom center of said base and integrally therewith, a solid anchoring stud having a rounded lower end; and in the ground surface, at least one sleeved dug hole shaped and dimensioned to fit closely around said stud; said anchoring stud being free from vertical restraint in relation to said dug hole other than the combined weight of said post base and stud.
Claim 3
Dependent Claim
