Abstract

A flexible tube is suspended from a support arranged to be mounted adjacent a vehicle light surface to be cleaned. The support has an inlet for admitting compressed air to the tube whereby upon selected pressured flow of air through the tube, the tube whips back and forth in a flogging action to clean foreign material from the surface. The support also has an inlet for a cleaning solution used in combination with the whipping tube. The tube has a shape in cross section that tends to maintain it in the plane of the surface being cleaned. In modifications of the invention, a guide is provided to hold the tube in close to the surface being cleaned, and apertures are provided in the tube so that air pressure urges the tube toward the surface.

Claims

1. A cleaning device for the lens surface of vehicle lights having a support frame, said device comprising

(a) support means arranged to be mounted on said light adjacent said lens surface,

(b) a flexible tube having opposite ends,

(c) one end of said tube being secured to said support means for support adjacent said lens surface,

(d) the other end of said tube being open,

(e) said tube being supported in substantially parallel relation with said lens and in overlapping engagement therewith,

(f) and means at the supported end of said tube for admitting pressured fluid whereby upon selected pressured flow of fluid through said tube, said tube whips back and forth in flogging engagement with said surface to beat foreign material off said lens surface.

2. The cleaning device of claim 1 wherein said means for admitting said pressured fluid comprise air inlet means, and means at the supported end of said tube for directing a liquid against said lens surface to assist said tube in cleaning.

3. The cleaning device of claim 1 wherein said tube has a greater dimension in its body thickness that extends at right angles to the lens surface than the body thickness that extends parallel to said surface whereby the whipping action will mostly be confined in a plane parallel with the lens surface.

4. The cleaning device of claim 1 wherein said tube is oval in cross section and is supported by said support means with its major axis extending approximately at right angles to the lens surface.

5. The cleaning device of claim 1 wherein said tube has exterior radial rib means extending approximately at right angles to the lens surface.

6. The cleaning device of claim 1 including guide means confining the whipping action of said tube in a plane substantially parallel with the lens surface.

7. The cleaning device of claim 1 wherein said tube has aperture means on the side thereof opposite from the lens surface whereby pressured outflow of fluid from said aperture means urges said tube toward the lens surface.

8. The cleaning device of claim 1 wherein said support means is arranged to be secured to the support frame of the vehicle light, said support means including air inlet means communicating with said tube for providing air as said compressed fluid, said support means also including cleaning liquid inlet and discharge means, the said discharge means being directed toward the lens surface for directing a cleaning liquid against the lens surface to assist said tube in cleaning.
