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.
Claims7
A mechanism for line striping and designed to be attached to a vehicle, said mechanism comprising:
- a frame;
- means for attaching said frame to said vehicle at least two points allowing said frame to move only vertically;
- a ground-engaging wheel mounted to said frame, said wheel being mounted so as to be capable of swiveling about a generally vertical axis relative to said frame and to rotate about a generally horizontal axis, said ground-engaging wheel being capable of rollably supporting said mechanism during striping operations and being the sole point of contact;
- and
- means for applying a stripe attached to said frame.
A mechanism for line striping and designed to be attached to a vehicle having a direction of travel, said mechanism comprising:
- a frame having first and second sides;
- means for attaching said frame to said vehicle;
- a main beam releasably attached to said frame perpendicular to said direction of travel and extendible to either of said sides without removal from said frame;
- a pivoting boom arm slideably and releasably clamped to said main beam and being slideable to either of said sides without removal from said frame;
- and
- means for applying a stripe attached to said frame.
A mechanism for line striping and designed to be attached to a vehicle having a direction of travel, said mechanism comprising:
- means for striping;
- means for the operator of said vehicle to sight a desired point along a line to be striped ahead of said vehicle;
- means for measuring and storing the delay distance between said striping means and said desired point;
- means controlling said striping means so as to utilize said delay distance to initiate a striping action with said striping means at said desired point.
