Abstract
An improved apparatus for attaching a flexible marker shaft to a roadway. The flexible lower part of the marker shaft slides over a mandrel, and into a maker shaft cavity. Locking wedges are positioned in the cavity to surround and support the flexible marker support shaft in the cavity. A locking pin passes through a locking pin hole and locks the wedges and the marker shaft into the marker shaft cavity.
Claims19
A mounting base for supporting a marker support shaft of a highway marker comprising in conjunction:
- a base plate having a top surface and a bottom surface, the bottom surface suitable for attaching the base plate to a road surface;
- a marker shaft cavity extending from the top surface and having a plurality of cavity walls;
- an upward protruding mandrel joined to the base plate and located within the marker shaft cavity, the exterior of the mandrel defining a clearance between the mandrel and the marker shaft cavity wall, the clearance being of suitable shape as to receive the marker support shaft, the marker support shaft having a lower end with a receptacle which slides over the mandrel and locates in the cavity;
- a locking pin hole extending through the base plate, into the marker shaft cavity, and into the mandrel, the lower end of the marker support shaft having a locking pin hole that registers with the locking pin hole of the base and mandrel;
- and
- a locking pin passing through the locking pin holes of the base, lower end of the marker support shaft, and the mandrel, for locking the marker support shaft to the base plate.

A highway marker comprising in combination:
- a base plate having a top surface and a bottom surface, the bottom surface suitable for attaching the base plate to a road surface;
- a marker shaft cavity extending from the top surface and having a plurality of cavity walls;
- an integrally formed upward protruding mandrel joined to the base plate and located within the marker shaft cavity, the exterior of the mandrel defining a clearance between the mandrel and the marker shaft cavity wall, the clearance being a suitable shape as to receive the marker support shaft, the marker support shaft having a lower end which slides over the mandrel and locates in the cavity;
- a marker support shaft having a lower end that extends into the cavity, the lower end having a locking pin hole in the marker shaft, for locking the marker support shaft to the base plate;
- at least one locking wedge positioned in the cavity between the marker shaft cavity walls and the marker support shaft, the locking wedge surrounding and supporting the marker support shaft in the cavity;
- a locking pin hole extending through the base plate transverse to the marker support shaft, into the marker shaft cavity, through the locking wedge, and through the mandrel;
- a locking pin passing through the locking pin hole in the base plate, locking wedges, into the locking pin hole in the marker shaft, and through the mandrel, for locking the marker support shaft to the base plate.
