Abstract

An apparatus mountable on a vehicle is provided for pre-marking pavement for striping or lining comprising a distance sensor which emits an infrared light beam toward the roadway edge or curb, where it is reflected by a reflector mounted on a stick held by a roadway worker. The reflected light is received by a beam receiver, and the distance of the vehicle from the roadway edge is computed and provided to a marking device, which has a paint gun movable transversely on a carriage guide to position the paint gun a predetermined distance from the roadway edge and mark the pavement in response to the distance measurement.

Claims

1. Apparatus mountable on a vehicle for marking pavement on a roadway for striping by placing pre-striping marking lines a predetermined distance from the edge of the roadway comprising:

distance determining means for determining the distance that a portion of the vehicle is from the edge of the roadway; and

marking means responsive to said distance determining means for marking the pavement a predetermined distance form the roadway edge, comprising means for holding a paint marking gun and means for moving a paint marking gun relative to the vehicle and toward and away from the roadway edge in response to he distance determining means, to locate the paint marking gun a predetermined distance from the roadway edge.

2. Apparatus according to claim 1, wherein the distance determining means comprises:

beam emitting means for emitting a beam toward the roadway edge;

beam reflecting means at the roadway edge for reflecting the beam toward the beam emitting means;

beam receiving means for receiving the reflected beam; and

means responsive to the beam receiving means for producing a signal indicative of the distance that the vehicle portion is from the roadway edge.

3. Apparatus according to claim 1, wherein the marking means comprises a marking gun movable toward and away from said roadway edge and means for positioning the marking gun a predetermined distance from the roadway edge.

4. Apparatus according to claim 2, wherein the beam emitting means comprises an infrared beam emitter.

5. Apparatus according to claim 3, wherein the marking means comprises a marking gun carriage guide, a gun carriage movable on said marking gun carriage guide toward and away from said roadway edge, and a paint marking gun mounted on said gun carriage.

6. Apparatus according to claim 1, wherein the distance determining means and the marking means are mounted on the front bumper of the vehicle.

7. Apparatus according to claim 1, wherein the roadway edge has a curb.

8. Apparatus according to claim 2, wherein the beam reflecting means comprises a reflector mounted on a stick.
