Abstract

A portable vacuum cleaner has a two-part housing comprised of an upper part and a lower part, a handle attached to the upper part by two enlarged substantially arcuate shaped end portions on the handle, a recess formed between the arcuate portions and a part of the housing for the removable storage of accessories such as nonflexible extension tubes, a motor within the housing, a rechargeable battery within the housing to drive the motor, a turbo-impeller within the housing operatively connected to the motor to be driven thereby, a dust collecting means in the housing, a dust filter surrounding the impeller and protecting the impeller and motor from dust collected in the dust collecting area, and an opening in the housing for the attachment of accessories operably connected to the suction circuit produced by the impeller.

Claims

1. A portable vacuum cleaner comprising:

a housing having an upper part and a lower part;

means for detachably connecting said upper and lower parts together;

a handle on said upper part having an elongated hand grip portion;

a substantially arcuately shaped enlarged portion at each end of said handle connecting said handle in spaced relationship to said upper part so that an opening is provided between said handle and said upper part to accommodate at least part of the user'"'"'s hand;

a recess on at least one side of said handle extending within said housing formed between said arcuately shaped portions and said upper part having a shape similar to accessories to be used with the vacuum cleaner and adapted to receive said accessories so that said accessories are removably insertable into said recess to be substantially completely contained therein within the external surface of the housing;

means in said recess on said upper part to removably fasten said accessories within said recess so that said accessories do not extend substantially beyond the outer surface of said housing;

an elongated shoulder strap device attached at its ends to said housing to support said housing thereby;

suction producing means within said housing;

dust collecting means within said housing operatively connected to said suction producing means; and

an opening on said housing to operatively and removably connect accessories to said suction producing means.

2. A vacuum cleaner as claimed in claim 1 wherein said suction producing means comprises:

an electric motor mounted within said upper part of the housing;

a rechargeable battery mounted within the housing and operatively connected to said motor to drive said motor; and

a turbo-impeller operatively connected to said motor to be driven thereby and disposed within said lower part of the housing, and rotatable about an axis extending substantially perpendicular to the axis of said accessory connecting opening and spaced therefrom.

3. A vacuum cleaner as claimed in claim 2 wherein said dust collecting means comprises:

said lower part of the housing; and

a dust filter operatively mounted between said lower part of the housing and said impeller and motor so that said impeller and motor are screened from dust drawn into said lower part by said impeller.

4. A vacuum cleaner as claimed in claim 3 wherein said housing is contoured so that the edges thereof are rounded and smooth.

5. A vacuum cleaner as claimed in claim 4 wherein a said recess is provided on both sides of said handle and are provided with said removable fastening means for accessories.
