Abstract
A top brush interrupt system for a vehicle wash system particularly adapted for pickup trucks that includes a top brush rotatable on a generally horizontal cross shaft that journalled in a pair of spaced arms that are pivoted on a frame for movement toward and away from the top of the vehicle to be washed. The interrupt system includes a proximity switch on the frame cooperating with a proximity target on one of the arms for sensing when the top brush is in position on top of the vehicle and for indicating when the top brush is not on the top of the vehicle and associated circuitry including timing means for terminating rotation of the top brush and/or raising the top brush from the vehicle.
Claims9
A vehicle wash system for both an automobile vehicle and a pick-up truck vehicle, said automobile and pick-up truck vehicles each defining a front, a passenger area, a generally horizontal top over said passenger area, a lower rear portion, and a drop off, said drop off defined generally by a boundary between said top and said lower rear portion, comprising, in combination:
- a frame for moving over said vehicle;
- a top brush rotatably carried by said frame, said top brush rotatable about a generally horizontal axis for washing said vehicle, said top brush moving upward, to wash said top of said vehicle, and lowering, from said top to said lower rear portion of said vehicle, to wash said lower rear portion of said vehicle, as said frame moves over said vehicle;
- measurement means for measuring distance from said front of said vehicle to said drop off of said vehicle and responsively producing a measurement signal;
- and
- interrupt means, interconnected to said measurement means, for receiving said measurement signal and selectively controlling said lowering of said top brush.
