Highway traffic lane and road edge reflectors

In a reflector of the kind to be placed between highway traffic lanes and at road edges and the like for traffic guidance by light reflected therefrom;

• the improvement comprising:
• a housing rising gradually from a location about the perimeter of the housing where, in use, said housing intersects the road surface,
• at least one reflective element recessed within the housing,
• a light channel opening from the exterior of the housing to the reflective element,
• the housing having a shoulder on each side of the channel,
• a bridge spanning the channel;
• and
• a base portion adapted for location below the surface of a road, said base portion having a recess therein, the reflective element including a mounting means extending below the reflective element into the recess, means located entirely below the road surface cooperating between the recess and the mounting means, for locking the reflective element and mounting means in place and the reflective element having a height extending substantially the entire distance from the plane of the road surface to an under-surface of the bridge.

In a reflector of the kind to be placed between highway traffic lanes and at road edges and the like for traffic guidance by light reflected therefrom;

• the improvement comprising:
• an upper housing,
• a lower base,
• a reflector assembly insertable and removable as a unit protectively recessed within said housing in a light channel opening thereto and including at least one reflective element and a support therefor,
• and interfitting means on the interior of the light channel and the support for securing the reflector assembly removably in place, said interfitting means including means slidably receiving the support.

In a reflector of the kind to be placed between highway traffic lanes and at road edges and the like for traffic guidance by light reflected therefrom;

• the improvement comprising:
• an upper housing,
• a lower base,
• a reflector assembly protectively recessed within said housing in a light channel opening thereto and including at least one reflective element and a support,
• and interfitting means on the interior of the light channel and the support for securing the reflector assembly removably in place,
• the base being integral with the housing and adapted to be bolted to the road, and
• including at least one elongate bolt having a head with coded drive provisions thereon adapted for driving engagement by a cooperatively coded drive tool, whereby said bolt resists unauthorized removal of the reflector.

In a reflector of the kind to be placed between highway traffic lanes and at road edges and the like for traffic guidance by light reflected therefrom;

• the improvement comprising:
• an upper housing,
• a lower base,
• a reflector assembly protectively recessed within said housing in a light channel opening thereto and including at least one reflective element and a support,
• and interfitting means on the interior of the light channel and the support for securing the reflector assembly in place, and
• the reflector assembly being accessible through the light channel communicating from the housing exterior to the at least one reflective element, an elongate recess formed in the floor of the light channel, said reflector assembly support fitting in sliding relation into said recess, a slot in the under side of said support, a downwardly biased leaf spring secured in the slot, a projection extending upward from the bottom of the recess and located to be abutted by the end of the leaf spring to prevent removal of the reflector assembly.

In a reflector of the kind to be placed between highway traffic lanes and at road edges and the like for traffic guidance by light reflected therefrom;

• the improvement comprising:
• an upper housing unit gradually rising from a location about the perimeter of the housing unit where, in use, said housing unit intersects the road surface,
• a light channel opening into the upper housing unit,
• a reflector assembly secured in the light channel,
• a lower base unit adapted to be secured to the road and located entirely at or below a level substantially flush with the surface of the road,
• means detachably connecting the upper housing unit and the lower base unit and adapting said upper housing unit for repeated seasonal removal to leave the roadway free of residual parts protruding substantially above the road level;
• said upper housing unit and lower base unit forming a binary system of two separable unitary parts;
• whereby removal of the housing unit effects removal of the reflector assembly and all parts of the reflector substantially above the road level.

In a reflector of the kind to be placed between highway traffic lanes and at road edges and the like for traffic guidance by light reflected therefrom;

• the improvement comprising:
• an upper housing portion gradually rising from a location about the perimeter of the housing portion where, in use, said housing intersects the road surface,
• a lower base portion adapted to be secured to the road, and
• means detachably connecting the upper housing portion and the lower base portion,
• one of said housing and base portions including plural lugs extending from a circular wall thereof, and the other of said housing and base portions including cooperating circularly arranged slots larger than said lugs and having openings for receiving the lugs, whereby said reflector is assembled by placing the lugs in the lug receiving openings and turning the housing portion relative to the base portion,
• the base portion having a circular peripheral outer wall and said lugs and slots being circularly arranged inwardly of the outer wall,
• the slots extending circularly beyond the lug openings, said lugs when located in the slots with said housing portion turned in locked relation leaving at least one accessible portion of a lug opening, a locking wedge being dimensioned to fit said open portion and prevent return rotation of the housing.
