Self cleaning pavement marker

A self-cleaning pavement marker adapted to be installed in a groove below the plane of the driving surface of an associated roadway to provide a retroreflective light signal visible to an oncoming vehicle. The marker comprises an integrally formed elastomeric body adapted to be positioned in a longitudinally extending groove cut in the roadway surface. The body includes an upper portion for receiving a retroreflective lens means. The lens means is effective a retroreflect light impinging upon its front face from an oncoming vehicle back toward the vehicle. The upper body portion of the marker is depressible between a normal position wherein the lens means is positioned below the plane of the associated roadway to retroreflect light impinging on the front face from an oncoming vehicle back toward the light source, and a depressed position caused by the force of a vehicle tire passing over the upper body portion. Wiping means is positioned below the plane of the associated roadway and is integrally formed with the body, and is positioned adjacent to the front face of the lens means, and is configured and arranged such that the wiping means does not interfere with the retroreflective function of the lens means when the body portion is in the normal position. Upon depression of the upper body portion to the depressed position, and its return to the normal reflecting position, the front face of the lens means moves past the wiping means and in direct contact therewith, whereby the wiping means effects a debris-cleaning and wiping function. The marker is effective as a snowplowable marker, particularly where studded tires are permitted. |

DETAILED DESCRIPTION The invention, in its preferred embodiment, comprises a selfcleaning pavement marker adapted to be installed in an elongated groove provided in the associated roadway surface, in a fashion such that the marker normally is disposed substantially entirely below the plane of the driving surface of the associated roadway.
The elastomeric body includes an upper body portion for receiving a retroreflective lens means, the retroreflective lens means being secured to the upper body portion and includes a front face and retroreflective system effective to retroreflect light impinging on the front face from an oncoming vehicle back toward the vehicle.
The upper body portion is positionable between a normal, non-depressed reflecting position, wherein the lens means is positioned to retroreflect light toward the light source, while still being positioned below the roadway surface, and a depressed position caused by the force of a vehicle tire passing thereover.
Wiping means, also located below the plane of the associated roadway, is positioned adjacent to the front face of the lens means, to effect a wiping action upon the front face as the lens means is moved between the normal reflecting position, and the depressed position.
The wiping means effects a debris-cleaning and wiping function on the front face so as to retain a high percentage of the reflector's brightness over an extended time period.
In the preferred embodiment, the elastomeric member including the body potion and wiping means is a single, integrally formed extruded member og a gewnerally G-shaped configuration.
It is easily positionable and affixed to the groove cut in the underlying roadway surface.
The retroreflector lens means includes a lens holder to which the retroreflective is secured, a metal cap for protecting the lens and lens holder from studded snow tires which pass thereover, and a lens having retroreflective system therein.
The lens holder is a generally T-shaped member having a leg portion which is adapted to be secured within a receiving slot in the upper body portion and a cross member to which the retroreflective lens is secured, whereby depression of the upper body portion by the force of the vehicle tire passing thereover moves the retroreflective lens means relative to the wiping means to clean debris therefrom
