Abstract
A pair of diametrically offset flaps of feltlike fabric are mounted at opposite ends of a filament-strand carwasher brush to clear the brush strands away from mirrors and antennae as the vehicle is washed.
Claims8
A brush for washing a vehicle comprising:
- a rotary shaft having an axis of rotation;
- a plurality of strand-like elements substantially uniformly attached around and along said shaft to form a rotary brush;
- and
- at least one solid flexible paddle attached to said rotary shaft among and circumferentially interleaved between the elements and offset from the center of said brush, the width of said paddle along the brush shaft axis being substantially less than the overall width of said brush but great enough to overlie a plurality of said elements, said paddle being extendible radially outward by centrifugal force upon rotation of said rotary shaft to prevent the brush elements from becoming entangled with external components of a vehicle.
1 more element
A vehicle washing brush comprising:
- a rotary shaft;
- a plurality of brush element sections wrapped around said shaft in side-by-side relationship;
- each section including a flexible base and a plurality of flexible brush elements attached to said base to extend radially from said shaft axis when said shaft is rotated;
- each of said section bases being disposed around said shaft and overlapped end-to-end to define an overlap area, each said section being fastened in the overlap area;
- and
- a solid flap of flexible material fastened to at least one of the sections in the overlap area thereof and excluding from said section circumferentially between the elements thereof.
