Abstract

A disposable bag filters dirt particles and the like from exhaust air of a hand-held vacuum cleaner. The motor housing of the vacuum cleaner receives a conventional reusable bag thereon and an adaptor facilitates changeover of existing vacuum cleaners to accommodate the disposable bag. A reinforcing member is provided on the disposable bag and is dimensioned for a friction fit with the adaptor. Another preferred embodiment incorporates a seal member into the assembly to enhance the sealing integrity between the adaptor and disposable bag.

Claims

1. A hand-held vacuum cleaner comprising:

a housing having suction means defined therein;

an adaptor having a passage defined therethrough an operatively connected to said housing, said adaptor having an inner end including a rim portion having a minimized axial dimension relative to a total axial dimension of the adaptor, a steeply sloping portion extending radially inward from the rim portion toward a generally tubular portion defined at an outer terminal end of the adaptor axially spaced from said inner end, said sloping portion extending only partially around the periphery of the adaptor, a connecting flange completing the periphery of the adaptor between the rim portion and generally tubular portion and an exterior surface of said generally tubular portion radially increasing from a narrow dimension adjacent the outer terminal end to a wide dimension adjacent the sloping portion;

a first, resuable bag selectively engaging said housing and adapted for covering relation with said adaptor;

a second, disposable bag selectively engaging said adaptor for filtering dirt particles and the like from exhaust air exiting from said suction means; and

,

a double-sided adhesive tape disposed on an interior portion of said rim portion facilitating connection between said adaptor and housing.

2. The hand-held vacuum cleaner as defined in claim 1 wherein said second bag includes a generally closed bag portion having an opening of first dimension defined through one end thereof, a reinforcing member having first and second opposed faces with an opening of second dimension extending therethrough, said second dimension closely approximating said first dimension and said reinforcing member having said first face in generally facing relation to said bag portion one end whereby said reinforcing member closely surrounds said bag portion opening and said reinforcing member opening second dimension being less than said adaptor tubular portion wide dimension whereby said second bag is friction fitted to the adaptor.

3. The hand-held vacuum cleaner as defined in claim 2 further comprising a seal member cooperating with said second bag to enhance a sealing relation between said adaptor and second bag.

4. The hand-held vacuum cleaner as defined in claim 3 wherein said seal member has an opening extending therethrough having a third dimension, said third dimension being less than said first and second dimensions whereby said seal member extends axially along a peripheral portion of said adaptor and is received through said second bag opening and reinforcing member opening.

5. The hand-held vacuum cleaner as defined in claim 1 wherein said adaptor includes means for selectively engaging an associated blower attachment whereby said hand-held vacuum cleaner may be used as a blower.

6. The hand-held vacuum cleaner as defined in claim 1 further comprising an aperture in said connecting flange adapted to receive a mechanical fastener for connecting said adaptor to the housing
