Claims Analysis
Total Claims: 4
Claim 1
Independent Claim
209 words
A highway right-of-way delineator post of the ''''lay-down'''' type, including a lower section, the major portion of which is embedded in the ground, and an upper above-ground section, hinge means connecting said lower and upper sections together, whereby said upper section may be moved relative to said lower section, said hinge means comprising a bifurcated lower end on said upper section providing a pair of spaced-apart legs and a free area therebetween, one of said legs being shorter than the other, a rod fixed to and extending through a portion of the lower section which is above ground, said rod being received in said free area between said legs when the upper section is in position aligned with said lower sectioN, and a further rod fixed to end extending from the upper portion of said lower section above said first named rod, and said upper section being pivotally mounted on said further rod, said upper section having an elongated slot therein and said further rod extending therethrough, the shorter leg being substantially equal to the length of the slot, whereby upon axial movement of said upper section the shorter leg is cleared from said first named rod for pivoting movement of said upper section relative to the lower section.
Claim 2
Dependent Claim
