Snowplowable road marker

Abstract

An improved casting for a road marker having a reflector and a method of installation for the road marker are disclosed. The method of installation includes forming a groove that has a rectangular geometry when view from above and is longitudinal oriented parallel to the direction of the road. The groove can also have a deeper section at the center with the same geometry of the groove but with a bigger radius to receive one or more legs from the road marker of the present invention.

1 ) A base for a snowplowable roader marker for securing a reflector and having a longitudinal axis, the base comprising:
 a top surface;   a bottom surface;   at least one leg extending outwardly from the bottom surface, the at least one leg being perpendicular to the longitudinal axis of the base.   
     
     
         2 ) The base for a snowplowable road marker of  claim 1  wherein the one or more legs comprise a center leg and a plurality of transverse legs. 
     
     
         3 ) The base for a snowplowable road marker of  claim 2  wherein the center leg extends further from the base than the transverse legs. 
     
     
         4 ) The base for a snowplowable road marker of  claim 2  wherein the transverse legs and center leg are connected at the bottom surface by a flange, the flange being perpendicular to the longitudinal axis of the base. 
     
     
         5 ) The base for a snowplowable road marker of  claim 4  wherein the transverse legs and center leg extend from the flange in a radial manner. 
     
     
         6 ) The base for a snowplowable road maker of  claim 1  further comprising:
 a plurality of tabs, the tabs extending from a perimeter of the base; 
 wherein the tabs rest on top of the road to which the maker is to be installed. 
 
     
     
         7 ) The base for a snowplowable road marker of  claim 1  wherein the top surface has a pair of rails running outside an area in which the reflector can be installed. 
     
     
         8 ) The base for a snowplowable road marker of  claim 7  wherein the rails are wider near an end of the base and increasingly narrow towards a middle of the base. 
     
     
         9 ) The base for a snowplowable road marker of  claim 8  wherein the bottom surface has a plurality of recesses, the recesses being deeper under the rails of the top surface. 
     
     
         10 ) The base for a snowplowable road marker of  claim 1  wherein the bottom surface has a generally arcuate shape, with the curve of the arcuate shape being normal to the longitudinal axis of the base. 
     
     
         11 ) A method for installing a marker in a road surface, the method comprising:
 providing a road surface, a road marker, and an adhesive;   cutting a longitudinal groove in the road surface, the groove having a longitudinal axis running parallel to a direction of travel of the road surface;   cutting a center groove in the longitudinal groove, the center groove extending deeper in the road surface than the longitudinal groove, the center groove having a longitudinal axis parallel to the direction of travel of the road surface;   attaching the road marker to the road surface in the longitudinal groove and center groove with the adhesive.   
     
     
         12 ) The method of  claim 11  wherein the longitudinal groove and the center groove are cut as part of a single operation. 
     
     
         13 ) The method of  claim 11  wherein the longitudinal groove and the center groove have an arcuate cross sectional profile, the profile being perpendicular to the direction of travel of the road surface. 
     
     
         14 ) The method of  claim 11  wherein the longitudinal groove is approximately 2 centimeters deep. 
     
     
         15 ) The method of  claim 11  wherein the center groove is approximately 4 centimeters deep. 
     
     
         16 ) The method of  claim 11  wherein the center groove is twice as deep as the longitudinal groove.
