Abstract
Vehicle washing apparatus having two suspended brushes rotatable about generally vertical axes which are forced apart during passage of the vehicle between the brushes wherein the brushes are initially inclined towards the vehicle and are swung into an oppositely-inclined position by pressure against the vehicle, whereby the front and rear surfaces of the vehicle are more efficiently cleaned.
Claims7
An apparatus for washing front, side and rear surfaces of vehicles wherein a relative movement occurs between said apparatus and said vehicle, comprising:
- a frame;
- at least two brushes rotatably mounted on said frame about generally vertical axes of rotation which lie in planes parallel to the longitudinal axis of said vehicle and are initially inclined at an acute angle (.alpha.) with respect to the vertical in the direction of the relative movement of said vehicle relative to said frame whereby the bottom of said brushes are initially inclined toward the front of said vehicle prior to engagement of said front of said vehicle with said brushes;
- pivot means for pivotally supporting each of said two brushes for pivotal movement about horizontal axes transverse to said longitudinal axis of said vehicle;
- and
- track means on said frame for supporting said brushes for movement between positions adjacent said longitudinal axis of said vehicle for washing said front and rear surfaces of said vehicle along a path extending transversely of said longitudinal axis of said vehicle and remote from said longitudinal axis of said vehicle for washing said side surfaces of said vehicle.
