Abstract

A highway marker comprises a delineator unit and a base unit. The base unit is adhesively secured to a flat surface along the highway so as to indicate the side of the road, thereby serving as a guide for a motorists and maintenance workers. The delineator unit is separable from the base unit and replacement is easily achieved if necessary.

Claims

1. A highway marker comprising a disc member residing in a first plane, delineator means projecting from one side of said disc member, and a plurality of angularly spaced anchor fingers secured to the other side of said disc member in a second plane generally parallel to said first plane, a concavo-convex shell including a bottom peripheral edge, a platform in a plane offset upwardly from the plane of said peripheral edge, said platform having a plurality of angularly spaced notches for the accommodation of said fingers and intermediate locking lugs for engaging the upper sides of said fingers when said fingers are rotated out of registry with said notches, and rib means laterally outward of said notches and lugs and extending from beneath the lower surface of said shell into the plane of said peripheral edge providing adhesive-receiving pockets.

2. A highway marker in accordance with claim 1 in which said rib means includes a circular rib circumjacent said notches and lugs and a plurality of additional ribs between said cylindrical rib and said bottom peripheral edge.

3. A highway marker in accordance with claim 2 in which said additional ribs extend longitudinally and transversely.

4. A highway marker in accordance with claim 1 in which said delineator means includes a flat panel having a reflectorized surface on at least one side thereof nd said plurality of fingers includes a first pair of oppositely directed fingers and a second pair of oppositely directed fingers extending in a 90* relationship with said first pair, whereby said panel may be disposed in at least two perpendicularly oriented positions depending upon the angular orientation of said fingers.

5. A highway marker comprising a delineator unit including a disc member residing in a first plane, a mast projecting from one side of said disc member, and a plurality of angularly spaced anchor fingers secured to the other side of said disc member in a second plane generally parallel to said first plane, and a base unit having a peripheral edge residing in a third plane generally parallel to said first and second planes so as to permit said base unit to be adhesively secured to a substantially flat surface along the highway, said base unit further including a platform disposed in a fourth plane intermediate said first and second planes, said platform having angularly spaced notches for the accommodation of said fingers and intermediate locking lugs for engaging said fingers when rotated out of registry with the notches, each locking lug haVing a pair of rounded projections formed on the side thereof toward said peripheral edge and spaced apart a distance sufficient to accommodate therebetween a respective finger, said fingers having a curved surface so as to cam over said rounded projections when being rotated into a position therebetween.

6. A highway marker in accordance with claim 5 including a circular wall surrounding said platform, said wall extending away from said platform a distance generally equal to the thickness of said disc member.

7. A highway marker in accordance with claim 6 in which said disc member projects radially beyond the end of said fingers and said platform has an annular seal against which said disc member bears.

8. A highway marker in accordAnce with claim 7 including a shell, said platform and peripheral edge being integral with said shell, and said shell having a plurality of ribs forming recesses for the accommodation of adhesive.
