Baseboard dusters for vacuum cleaners

Claim 2

In a vacuum cleaner: a housing having sidewalls; holding means on each of the sidewalls having spaced dovetail openings; and a brush for mounting on each of said holding means, each said brush including bristles secured on an inverted U shaped frame having a dovetail cross section such that the legs of said frame are engageable into the correspondingly shaped openings on said holding means; whereby said brushes are held with their bristles extending substantially laterally from the opposite sidewalls of the housing thereby enabling said brushes to be used to sweep across the baseboards while the vacuum cleaner housing is being moved about to clean the carpet in a room.

Claim 3

In a vacuum cleaner as defines in claim 1 wherein the dovetail openings of the holding means on the sidewalls are provided by three pairs of molded projections spaced for receiving the ends and midportion of said inverted U shaped frame.

Claim 4

In a vacuum cleaner as defined in claim 1 wherein the dovetail openings of the holding means on the sidewalls are provided by a pair of spaced vertically disposed grooves formed on the front of a plate secured to each of the sidewalls.

Claim 5

In a vacuum cleaner as defined in claim 3 wherein the upper inner corners of said grooves are rounded to form a circular upper wall on each said plate which engages the rounded midportion of said inverted U shaped frame when the brush is joined on said holding means.

Claim 6

In a vacuum cleaner as defined in claim 1 wherein said housing encloses a suction fan for drawing air from a bottom inlet chamber formed on the front end thereof into a bag held on a handle thereof, and wherein said housing has openings on its sidewalls forming the sides of said inlet chamber, whereby the dust on said baseboards loosened by the brushes can be drawn by the fan into said bag.

Claim 7

A vacuum cleaner including a housing enclosing a suction fan for drawing air from a bottom inlet chamber formed on the front end thereof into a bag held on an upright handle thereof, said housing having an opening on its sidewall forming a side of said inlet chamber, and including a baseboard duster attachment for said housing comprising: a holding device in the form of a plate having a pair of spaced vertically disposed dovetail grooves formed on the front portion thereof with an opening therethrough between the grooves; means for securing said holding device on the sidewall of said housing with its opening aligned with the opening thereon; and a brush including an inverted U shaped frame having its end formed with a dovetail cross section and spaced to correspond to the openings of the grooves on said holding device; whereby the ends of said inverted U shaped frame can be inserted down into said respective grooves to form an interlocking dovetail joint between the brush and the holding device with the bristles of the brush extending substantially laterally from the sidewall of the housing thereby enabling said brush to be used to sweep across the baseboards while the vacuum cleaner is being moved about to clean the carpet in a room.

Claim 8

A vacuum cleaner including a housing enclosing a suction fan for drawing air from a bottom inlet chamber formed on the front end thereof into a bag held on an upright handle thereof, said housing having an opening on its sidewall forming a side of said inlet chamber, and including a baseboard duster attachment for said housing comprising: a holding device in the form of a plate having a pair of spaced vertically disposed dovetail grooves formed on the front portion thereof with an opening therethrough between the grooves; means for securing said holding device on the sidewall of said housing with its opening aligned with the opening thereon; and a brush including an inverted U shaped frame having its end formed with a dovetail cross section and spaced to correspond to the openings of the grooves on said holding device; whereby the ends of said inverted U shaped frame can be inserted down into said respective grooves to form an interlocking dovetail joint between the brush and the holding device with the bristles of the brush extending substantially laterally from the sidewall of the housing thereby enabling said brush to be used to sweep across the baseboards while the vacuum cleaner is being moved about to clean the carpet in a room.

Claim 9

The vacuum cleaner as defined in claim 6 wherein a baseboard duster attachment is similarly provided on the opposite sidewall of said housing.

Claim 10

The vacuum cleaner as defined in claim 6 wherein the lower ends of the inverted U shaped frame extend below the bottom edge of the holding device and wherein the bristles fan outwardly above and below the holding device so as to sweep over a large vertical range.

Claim 11

In a vacuum cleaner: A housing having sidewalls; a holding means on each of the sidewalls, each said holding means including a vertically disposed inverted U shaped rim portion having openings along the front face thereof; and lengths of bristles held in said openings such that they extend substantially laterally from the sidewalls of the housing to form brushes having inverted U shaped configurations; whereby said bristles can be used to sweep across the sides and upper edges of the baseboards of a room while the vacuum cleaner housing is being moved about to clean the carpet therein.

Claim 12

In a vacuum cleaner: A housing having sidewalls; a holding means on each of the sidewalls, each said holding means including a vertically disposed inverted U shaped rim portion having openings along the front face thereof; and lengths of bristles held in said openings such that they extend substantially laterally from the sidewalls of the housing to form brushes having inverted U shaped configurations; whereby said bristles can be used to sweep across the sides and upper edges of the baseboards of a room while the vacuum cleaner housing is being moved about to clean the carpet therein.

Claim 13

In a vacuum cleaner as defined in claim 9 wherein said openings along the inverted U shaped rim portion are spaced blind holes and wherein said lengths of bristles are held by their midpoints in said spaced holes by metal staples.

Claim 14

In a vacuum cleaner: a housing having sidewalls; a pair of holding means each comprising a body having an inverted U shaped rim portion with spaced openings on the front face thereof; means for anchoring lengths of bristles in each of the spaced openings on the face of said U shaped rim portion to form a brush; and means for securing said holding means on the respective sidewalls of said housing such that the front faces of said inverted U shaped rim portions are disposed in vertical planes; whereby said brushes are held with their bristles extending substantially laterally from the sidewalls of said housing thereby enabling them to be used to sweep across the sides and upper edges of the baseboards of a room while the vacuum cleaner housing is being moved about to clean the carpet therein.

Claim 15

In a vacuum cleaner: a housing having sidewalls; a pair of holding means each comprising a body having an inverted U shaped rim portion with spaced openings on the front face thereof; means for anchoring lengths of bristles in each of the spaced openings on the face of said U shaped rim portion to form a brush; and means for securing said holding means on the respective sidewalls of said housing such that the front faces of said inverted U shaped rim portions are disposed in vertical planes; whereby said brushes are held with their bristles extending substantially laterally from the sidewalls of said housing thereby enabling them to be used to sweep across the sides and upper edges of the baseboards of a room while the vacuum cleaner housing is being moved about to clean the carpet therein.

Claim 16

In a vacuum cleaner as defined in claim 11 wherein said means for securing said holding means on the respective sidewalls of said housing include strips of adhesive tape on the back wall of said body and a hole in the center thereof to enable a screw to pass therethrough to threadably engage said sidewall.
