Ceiling fan brush and adjustable angle tube vacuum connector for same
First Claim
1. A ceiling fan brush for vacuum cleaning of thin, elongated, planar ceiling fan blades having laterally opposed, longitudinally extending opposite side edges, said ceiling fan brush comprising:
- an elongated body, a plenum chamber within said body and opening to one face of said body, a pair of side brushes mounted on said one face and projecting outwardly thereof, spaced laterally from each other and extending over the major length of said body, a pair of longitudinally opposed end brushes, spanning transversely across the body on said one face and projecting outwardly of said one face in the same direction as said side brushes and forming with said side brushes a vacuum chamber with the tips of said side brushes in contact along each face of said thin elongated planar ceiling fan blade, the end brushes having bristles of a length in excess of the length of the bristles forming said side brushes and being spaced from each other a distance generally equal to the lateral width of the ceiling fan blades to thereby engage respective opposite side edges of said elongated planar ceiling fan blades, and means carried by said body and opening to said plenum chamber for coupling said plenum chamber to a source of vacuum pressure such that said ceiling fan brush, when moved longitudinally over the surface of the fan blade, dislodges accumulating dust from the surface of the fan blade and said dust is sucked into the plenum chamber under vacuum pressure for effectively removing the dust from the ceiling fan blades.

Abstract
An elongated body, has internally formed a plenum chamber opening to one face of the body. A pair of side brushes mounted on the face projected outwardly thereof and being spaced laterally from each other and extending over the major length of the body. A pair of longitudinally opposed end brushes spanned transversely across the body face from one side brush to the other project outwardly of the one face in the direction of the side brushes and form with the side brushes a vacuum chamber. The tips of the side brushes are formed of bristles of a length in excess of the length of bristles formed by the side brushes, and are engageable with laterally opposed longitudinally extending opposite side edges of planar ceiling fan blades. The side brushes are spaced from each other a distance generally equal to the lateral width of the ceiling fan blades. Locking plates fixed to the body project outwardly from opposite ends of the body longitudinally outside of the end brushes and in contact therewith such that the ceiling fan brush is effectively locked by the locking plates to the opposite side edges of the fan blade to facilitate dust removal from the surface of the fan blade enveloped by the ray of side brushes and end brushes while mechanically guiding the ceiling fan brush during travel longitudinally over the surface of the ceiling fan blade from one end to another.
