Abstract
A "roll over" type vehicle wash apparatus includes a frame which is movable on a track and which is driven between a front end and a rear end of the track. The apparatus includes a pair of front arms and a pair of rear arms which are pivotally connected to the frame. Side wrap brushes are rotatably connected to each of the front and rear arms and are rotated about vertical axes. Positioned proximate the rear end of the track are arm deflectors which cause the rear arms to be driven inward toward one another as the frame approaches the rear end. This prevents the rear arms of the apparatus from being accidentally driven through doors at the ends of the bay area in the event of a failure of the actuators of the rear arms.
Claims16
A roll-over type vehicle wash apparatus comprising:
- track means having a front end and a rear end;
- frame means movable on the track means between the front end and the rear end;
- first and second front arm means pivotally connected to opposite sides of the frame means;
- first and second front side wrap brush means rotatably connected proximate free ends of the first and second front arm means, respectively;
- first and second rear arm means pivotally connected to opposite sides of the frame means;
- first and second rear side wrap brush means rotatably connected proximate free ends of the first and second rear arm means, to rotate about first and second vertical pivot axes, respectively;
- front actuator means connected between the frame means and the first and second front arm means for controlling the position of the front arm means to move the first and second front side wrap brush means into engagement with the vehicle;
- and
- rear actuator means connected between the frame means and the first and second rear arm means for controlling the position of the rear arm means to move the first and second rear side wrap brush means into engagement with the vehicle;
- means positioned proximate the rear end for engaging the first and second rear arm means and driving the free ends of the first and second rear arm means inward toward one another as the frame means approaches the rear end if the rear actuator means has not moved the first and second rear arm means inward toward one another.
A roll-over vehicle wash apparatus comprising:
- first and second substantially parallel horizontal rails defining a track having a first end and a second end;
- frame means movable on the track between the first end and the second end;
- first and second arms pivotally connected to opposite sides of the frame means to pivot about first and second generally vertical arm axes, respectively;
- first and second brushes rotatably connected proximate free ends of the first and second arm means to rotate about first and second generally vertical brush axes, respectively;
- actuator means connected to the frame means and the first and second arms for controlling the position of the first and second arms;
- and
- first and second upstanding members positioned proximate the first end of the first and second rails, respectively, for engaging the first and second arms to drive the arms so that the free ends of the first and second arms move inward toward one another as the frame means approaches the first end if the actuator means has failed to move the free ends of the arm means inward toward one another.
