ABSTRACT:
A battery-operated dust cup type, hand-held vacuum cleaner is provided with wall-mounted store-and-charge means that supports the cleaner in upwardly pointed position. The cleaner is also rechargeable independently of the storage bracket, using the same charging means. The flap valve associated with the vacuum nozzle of the cleaner is backwardly slanted from the intake mouth in closed position. The flap valve seals on a lip extending around the inner periphery of the nose end of the dust cup. The intake mouth is provided with a serration or comb forming a re-entrant lip at the bottom side of the mouth. The dust bag is mounted independently of the dust cup but also without use of special brackets forward of the vacuum intake. Latch means for the dust cup is mounted immediately adjacent the power switch, and is mechanically arranged to be "forgiving" of variations in manufacturing tolerance. The latch surfaces are hidden from sight and the latch mechanism is protected from dirt and dust within the dust cup by being isolated therefrom by sealing means. A novel sealing means is provided. The thin-walled plastic body forming the housing for the power components comprises two molded halves each of which has stiffening ribs partially penetrating the other in engaging relation. Pairs of posts extend transversely from the outer side walls of the two housing halves into mating and end-abutting relation with each other, and are fastened together in such relation.
