Abstract
A line striper is attached to a vehicle with a two point hitch and has a swivelable rotatable wheel mounted thereunder to support the striper on the ground. A main beam is releasably clamped and may be slid from side to side depending on operator preference. The gun boom may then be located on the desired side. A delay feature on the control allows the operator to look ahead on a sighting camera and pick the point at which he or she desires striping to start (or stop or any other operation). The controller then compensates for the calibrated distance between the sight point and the spray gun and then starts and stops the gun at the appropriate time given road speed.
Description
CA 022030~6 1997-04-18 ' VEHICLE TOWED APPARATUS FOR STRIPING OF ROADS
BACKGROUND OF THE INVENTION
Apparatus for striping roads which does not require a dedicated vehicle is shown in US Patent No. 5,368,232, the contents of which are incorporated by reference. While such a device is quite effective, one drawback is that limited amounts of weight may b e cantilevered off the rear end of a vehicle, particularly when th e 10 vehicle is smaller and/or has a relatively low load carrying capacity.
SUMMARY OF THE INVENTION
It is therefore an object of this invention to provide a n apparatus which may be attached to most any vehicle and yet which 15 may have a substantial amount of weight for the mechanism thereon.
It is further an object of this invention to provide a road striping apparatus which is easy to set up and operate by one person as compared to many of the prior art devices which require t w o operators .
It is further an object of this invention to provide a device in which a single paint applying boom may be easily and quickly switched from side to side and which may be easily placed in a transport position for transit between striping locations.
CA 022030~6 1997-04-18 It is yet further an object of this invention to provide a device which is easy to set up and which provides a delay which encourages efficient one operator operation.
The device is intended to apply stripes to roadways to either 5 match existing lines exactly or to apply new stripes per specification with one person operation. Such an operation is allowed by utilizing one person operation and providing a monitor delay system and e a s y to memorize finger touch controls. When the control system i s powered up, all gun controls are switched to a guns off position and 10 bead control is on; that is when any paint is turned on beads a r e applied to that paint. When powered off, all programmed skips, delays, and bead gun distances are retained in memory to be recalled f necessary.
The striping mechanism is designed for attachment to a towing 15 vehicle by means of a two-point hitch and the rear of the striping mechanism is supported by a swivel mounted support wheel which in the preferred embodiment has a damping mechanism as well a s spring mountings.
The support beam may be releasably clamped and moved from O side to side so that the spray gun boom arm may be utilized o n either side of the striping mechanism also by releasably clamping t o the beam.
The bead tank is provided with a concave spherically s h ap e d top having a central hole and a plug which is actually located in the ~5 tank and which may be pulled upwardly by means of a handle. Thus CA 022030~6 1997-04-18 when the plug is pulled upwardly and the tank pressurized, the tank is sealed yet the tank may easily be filled by releasing pressure a n d popping the plug downwardly. The plug is retained from falling into the tank by means of a handle which is wider than the hole. During 5 transport, the boom arm is swung upwardly and latched at the center of the mechanism. A gasoline engine powers a hydraulic power supply which in turn runs three hydraulic pumps for supplying of fluid at airless pressures to the three spray guns. The gasoline engine also powers a small air compressor which provides 10 air pressure to the bead supply unit.
The control provides an auto cycle set up switch which allows the operator to stay in the vehicle and program the controller t o place new lines over existing skip lines. When the auto cycle set u p button is pressed, the skip set up screen appears on the LCD screen 1 S and the skip cycle will be flashing . The operator then simply p u s h e s the mark button at the start and end of the cycle and the appropriate distance will appear on the LCD screen under the skip cycle. This c a n be accomplished at the same time the guns are painting by simply having the appropriate paint guns selected. For greater accuracy~ the 20 operator would want to stop on the first mark and then press mark then drive forward to the end of the cycle and stop again and press mark then back up and start painting. After the mark button h a s been pressed the second time, the auto cycle set up button turns off.
The cycle button can be changed any time thereafter by using 5 up and down arrow keys. The paint line length is a manual input a n d can be changed at any time. The three guns may be independently CA 022030~6 1997-04-18 switched on and off from one another and may either be switched into a solid striping regime or skip lines.
The delay button brings up the LCD screen for adjusting the feature monitor delay. The monitor delay is an important part of one 5 man operation and eliminates the need for the operator to look back at the guns when starting, stopping and line changes. Simply make all line selections at the appropriate time when the cross hairs on the monitor reach these points. The delay distance is the number of feet from this point back to the paint guns. The microprocessor simply 10 holds all keyboard commands for a set amount of traveled feet. The operator needs to watch the monitor for alignment purposes so i t makes sense to run the paint controls from the same view screen.
These and other objects and advantages of the invention will appear more fully from the following description made i n 15 conjunction with the accompanying drawings wherein like reference characters refer to the same or similar parts throughout the several vlews .

DESCRIPTION OF THE PREFERRED EMBODIMENT
The following table shows the components:
A Viscount I Hydraulic Motor Operates the displacement pump B Boom Arm Hitch Pin Secures spray gun boom arm when the Striper is in transport C Displacement Pump Provides fluid to be sprayed through spray gun D Fluid Filter Filters fluid between source and spray gun CA 022030~6 1997-04-18 E Breather Cap Provides a means for hydraulic reservoir ventilation, oil check and fill F Pressure Drain Valve Relieves fluid pressure when open G Fluid Outlet Tube Hose carries fluid from displacement pump to spray gun H Hydraulic Reservoir Holds 12 gallons of hydraulic oil for hydraulic pump Hydraulic Select/Bypass Selects displacement pumps Valve for guns 1 & 2, or 3; or bypasses all guns J Hub Allows trailer wheel to swivel K Hydraulic Pump Creates hydraulic pressure for the hydraulic power supply system L Main Beam Supports spray gun boom arm M Bead Tank Holds up to 300 lb. of glass beads for continuous spraying N Air Regulator Allows regulation of bead tank air pressure O Compressor Provides pneumatic supply to switch paint spray gun and bead spray guns on and off as directed by the programmable skipline control P Engine 18.0 HP gasoline engine CA 022030~6 1997-04-18 -R Tail Light Standard tail light that includes brake and directional lights S Hydraulic Pressure Knob Provides adjustment of hydraulic pressure. Clock wise rotation increases pressure. Pressure setting is locked with inner lock knob.
T Dolly Used to roll Striper into place for connection to tow vehicle and hold Striper upright when disconnected from tow vehicle and stored U Spray Gun Boom Arm Allows striping on either side of the tow vehicle at adjustable distances V Bead Spray Gun Sprays beads when commanded by the programmable skipline control W Paint Spray Gun Sprays fluid when commanded by the programmable skipline control X Fuel Tank Holds gasoline Figure 8 shows gun carriage 10 in its transport position when i t is swung up and locked. The paint pumps C in the preferred embodiment are a hydraulically (A) operated pump C of the Viscount line also manufactured by Graco Inc. When it is desired to paint, the 5 boom arm U is unlatched and slid to one end where it is locked using the latches 12, wherein it may then pivot and is supported by t h e road wheel 14.
CA 022030~6 1997-04-18 The framework 16 of the striping mechanism 10 itself attaches to the vehicle by means of two receivers 22 holding trailer hitch balls of conventional design. Thus the two-point hitch 18 (one side i s shown with an identical hitch on the other side) allows the striping S mechanism 10 to maintain absolute linearity with the vehicle 2 0 itself and does not suffer from articulation problems present i n typical trailers. A pivotable wheel 24 is located on the rear end of the striping frame to provide support and a damping mechanism 26 is utilized in hub J in order to prevent the swivel wheel 24 from 10 becoming unstable at speed.
Figure 10 shows the two point hitch 18 having a hitch frame 1 8A which is part of a normal frame mounted hitch such a s manufactured by DRAW-TITE. Two hitch receivers 18B are clamped to frame rail 18A as shown allowing use of standard hitches for the 1 5 two point hitch 18.
As can be seen on the frame 16, the three pumps Cwhich each are designed to pump two different colors (typically one being white and the other being yellow) are driven off a common gasoline engine P and hydraulic power supply J.
20A bead container M is utilized along with a small compressor O
driven off the same gasoline engine P and the bead container M is pressurized in order to supply beads to the bead gun V. The bead container M is provided with a knockout plug 60 of the t y p e commonly used in sandblasting equipment and a depressed upper - CA 022030~6 1997-04-18 surface 58 which allows easy loading of beads and quick locking and sealing of the container M.
As can be seen particularly in figure 7, wheel 24 rides on axle 28 and pivot member 30 which pivots about pivot point 32 on swivel fork 34. A spring pivot (36) mounts a pair of rod ends (38) which extend through springs 40, into mounting plate 42. Thus, rod e n d s (38) are always under tension and serve to compress springs 40, and under suspensions, loads will compress even more.
Swivel axle 44 extends upwardly from swivel 34 through 1 0 damping mechanism 46 in Hub J. One or more belleville washers (48) serve to preload a damping surface member (50) which may b e manufactured from an acetal homopolymer (lOOAF); which is impregnated with Teflon or a similar material.
As can be seen in the figures, the carriage rod/main beam L
may be unlocked and moved to either side of the vehicle and thence the boom arm moved to the outside of the carriage rod L so that the stripe may be positioned as desired. When it is desired to detach the striping mechanism from the vehicle, two supports T are cranked down by hand which lift the two hitch mechanisms 18 off the balls and allow the whole mechanism to be wheeled away from the vehicle .
Frame 16 has a channel 52 thereon, with a pair of clamps (54) of the over-center type serve to clamp and retain main beam L in the channel 52. Main beam L is desirably manufactured from a piece of square tubing with a piece of plate welded to one corner thereof, CA 022030~6 1997-04-18 with clamps 54 gripping the steel plate. Bolts (56) may be inserted on either end to limit the travel of main beam L. Upon reaching the job site, the operator may merely unlatch transport pin B a n d unclamp clamps 12 and 54. The operator can then extend main b e a m 5 L to the side on which it is desired a stripe and spray gun boom arm (U) moved outwardly to the striping position and clamp 12 locked again with boom U lowered so that road wheel 14 contacts t h e ground. The spray guns (W), may then be positioned as desired along with bead guns (V).
Bead guns V are shown in more detail in Figure 9 and have a teardrop shaped needle 64 which reduces chattering by encouraging laminar flow therethrough.
The attached operation instructions show the menu flow chart for the controller and help explain set up and operation. The 15 following table expands on the controls shown in Figure 3 :
Switch/Indicator Explanation A POWER ON/OFF switch ON enables battery DC power to the Control and to the engine. OFF
removes power from the Control and the engine. Engine can not be started when this switch is in the OFF position.

C RESET/HOLD switch HOLD disables paint guns 1, 2 and 3 and resets the internal cycle counter.
RESET resets the internal cycle counter but does not affect continuous line activity. If switch is held in RESET, a new cycle will not begin until the switch is released .
D ADV/RET switch Used in conjunction with the arrow switches to adjust the paint line position to match a previously painted line. ADV
allows the dash line to be moved forward. RET allows the dash line to be moved closer.
E BEADS ON/ BEADS TEST Enables/disables bead gun BEADS ON (up) - beads start to flow when paint guns start to paint.

As can be seen on the frame 16, the three pumps Cwhich each are designed to pump two different colors (typically one being white and the other being yellow) are driven off a common gasoline engine P and hydraulic power supply J.
20A bead container M is utilized along with a small compressor O
