Abstract

A hand-held cleaning device is disclosed comprising a two-piece, molded plastic housing having a top handle and a forwardly-extending snout-like sweep tunnel with a forwardly-inclined intake opening at its forward end and containing a driveable endless belt with spaced flexible sweeping blades thereon which pick up dust and debris at the intake opening and carry it through the tunnel to a material-receiving chamber within the housing. An illuminating system is located in the housing above the tunnel for alternately acting as a flashlight or a beacon, and a debris cup is removably mounted on the underside of the housing for collecting and disposing of material from the material-receiving chamber, which cup may also act as a prop for inclinedly supporting the device on a flat surface when the illuminating system is being used. Power cells and an electric motor are mounted within partitions molded integrally with the axially-mating housing halves, and respective switching arrangements are provided for energizing the electric motor and the illuminating system.

9. A device as in claim 7 further comprising means on the underside of said tunnel means, cooperating with said debris cup means when removed, for supporting said housing in an inclined position.

10. A device as in claim 1 further comprising:

electric power means in said housing for energizing said motor means;

switch means for electrically connecting said power means in circuit with said motor means and comprising;

contact means for opening and closing said circuit and having a first conductive member conductively connected to said power means and a second conductive member conductively connected to said motor means, said second member having a camming surface thereon;

plunger means for conductively closing said contact means comprising;

a plunger having a push-button on one end extending out of said housing and a camming surface on its other end in engagement with the camming surface on said second member and cooperating therewith to press said said second member into contact with said first member when said push-button is pushed downwardly toward said housing; and

spring means for urging said plunger outwardly from said housing.

11. A device as in claim 10 wherein said push-button is disposed immediately forward of said handle means.
