Abstract

A superior performance highway striping system is provided with various features including single person operation for different kinds of striping requirements and simplified automatic tracking around curved striping patterns provided by articulation at a ball joint between a towing truck and trailer paint striping unit. A common non-dedicated pick-up truck tows a trailer mounted modular paint striping system that may be broken down into a hand pushed parking lot type of striper sub-system or a ride behind motorized airport runway striper sub-system for a versatility of operational environments with one or two coat striping in multiple colors and widths. The towed trailer carries two 55 gallon paint drums of different colored paint, loaded and unloaded by a one person loading winch. Thus, the striping system controlled by a single person provides the versatility of on-highway and off-highway striping.

Claims

1. A paint striping system for automatic tracking around curved striping patterns, comprising in combination,

a towing vehicle structured for a driver to follow a striping pattern visible from the towing vehicle while driving the towing vehicle, said towing vehicle having a rear end trailer hitch extending therefrom to receive a trailing striping unit,

an unmanned striper trailer unit having a head end trailer hitch extending therefrom for coupling to the trailer hitch on said towing vehicle by an articulation joint comprising a universal joint connection, and

at least one paint striping gun mounted extending laterally from the striper trailer unit at a location rearward of said universal joint connection thereby to automatically track around curved paths in said striping pattern being followed as a function of the articulation of the towing vehicle and striper unit as the driver in the towing vehicle follows the striping pattern in front of the vehicle.

2. The paint striping system of claim 1 further comprising:

a video monitor visible to said driver in the towing vehicle without looking backward and to divert the eyes off-road,

paint striping control means available to said driver in the towing vehicle for control of striping from the paint striping gun in said striper unit when being towed by the towing vehicle, and

a video camera carried by the trailer unit to view at least one stripe being laid down for indicaing alignment and position referenced to the trailer unit of a striping pattern being painted by the paint striping gun.

3. The paint striping system of claim 2 further comprising a second video camera carried by the towing vehicle that monitors a striping pattern to be followed, and

means on said monitor for viewing both the pattern being followed and the striping pattern being painted simultaneously.

4. The paint striping system of claim 1 wherein said at least one paint striping gun further comprises means located upon and laterally extending from the towing vehicle ahead of the articulation joint to paint an initial stripe pattern and means comprising said laterally extended at least one striping gun on the trailer for painting a second stripe pattern coat in registration upon the initial painted stripe pattern.

5. The paint striping system of claim 1 with striping guns laterally extending from both the towing vehicle and trailer unit further comprising trailer hitch means disposed between the towing vehicle and the trailer unit for adjusting the distance between the universal joint and the striping guns.

6. A paint striping system for automatic tracking around curved striping patterns, comprising in combination,

a towing vehicle structured for a driver to follow a striping pattern visible from the towing vehicle while driving the towing vehicle, said towing vehicle having a rear end trailer hitch extending therefrom to receive a trailing striping unit,

a striper trailer unit having a head end trailer hitch extending therefrom for coupling to the trailer hitch on said towing vehicle by an articulation joint comprising a universal joint connection,

at least one paint striping gun mounted extending laterally from the striper trailer unit at a location rearward of said universal joint connection thereby to automatically track around a curved striping pattern as a function of the articulation of the towing vehicle and striper unit as the towing vehicle follows the striping pattern in front of the vehicle, and

a wheeled trailer unit having a load receiving bed and a removable hand steered paint striping unit removably affixed upon said load receiving bed adapted for control of stripe painting both when being towed by the towing vehicle and as a modular unit, said removable unit comprising a manual walk-behind unit with handlebar steering.

7. The paint striping system of claim 6 further comprising painting means for controlling the removable hand steered paint striping unit for dispensing paint for highway striping, and paint distribution means comprising at least one paint gun system mounted upon and extending laterally from said trailer unit for striping removably connected to the hand steered paint striping unit for the painting of highway stripes.

8. The paint striping system of claim 6 further comprising means located on said trailer to removably receive and secure in place at least one paint barrel.

9. The paint striping system of claim 8 further comprising a winch on the trailer unit for mechanically lifting paint barrels on to the trailer unit.

10. The paint striping system of claim 6 further comprising ramp means on said trailer unit for moving the hand steered paint striping unit on and off the trailer unit.

11. A paint striping system for automatic tracking around curved striping patterns, comprising in combination,

a towing vehicle structured for a driver to follow a striping pattern visible from the towing vehicle while driving the towing vehicle, said towing vehicle having a rear end trailer hitch extending therefrom to receive a trailing striping unit,

a striper trailer unit having a head end trailer hitch extending therefrom for coupling to the trailer hitch on said towing vehicle by an articulation joint comprising a universal joint connection,

at least one paint striping gun mounted extending laterally from the striper trailer unit at a location rearward of said universal joint connection thereby to automatically track around a curved striping pattern as a function of the articulation of the towing vehicle and striper unit as the towing vehicle follows the striping pattern in front of the vehicle, and

a paint striping system carried by said trailer having modular units removable from the trailer for one person operation in off-trailer locations including a walk behind paint striping unit and a ride on power driven striping unit.

12. The paint striping system of claim 11 further comprising, interconnected appliances disposed on the towing vehicle including a video monitoring and control system for in-cab viewing by said driver, a set of paint striping guns mounted to extend laterally away from either side of said towing vehicle, and disconnectable interconnections between the towing vehicle and the trailer for communicating with the interconnected appliances.

13. A multi-purpose paint striping system for on-highway and off-highway use, comprising in combination, a trailer adapted to be towed by a truck along a highway, and a modular paint striping system carried by the trailer comprising at least one operable paint-striping module for off-loading and operation by a single operator wherein said modular paint striping system comprises an articulated joint between the truck and trailer and paint striping guns extending laterally from at least one side of the joint configured to paint a stripe that tracks around curved paths.

14. A multi-purpose paint striping system for on-highway and off-highway use, comprising in combination, a trailer adapted to be towed by a truck alonf a highway, and a modular paint striping system carried by the trailer comprising at least one operable paint-striping module for off-loading and operation by a single operator, paint barrel mounting and securing means on a bed platform of said trailer, and a winch for lifting paint barrels up to the bed platform.
