Suction cleaner
First Claim
1. In a lightweight, upright vacuum cleaner, a base assembly including a suction nozzle, an elongated body housing, means attaching said body housing to said base assembly for pivotable movement relative thereto, said body housing including a motor housing assembly, a bulkhead assembly, a filter bag housing assembly, and a body closure assembly, means for securing said motor housing assembly, said bulkhead assembly and said filter bag housing assembly in assembled relation, means pivotably mounting said body closure assembly on said filter bag housing assembly, said filter bag housing assembly defining a vacuum chamber, air filter means supported within said vacuum chamber and including an apertured disk having an air-permeable bag secured thereto, said filter bag housing assembly including means for supporting said apertured disk adjacent outer peripheral edge portions, said body closure assembly including a duct terminating in a discharge nozzle, and seal means spaced substantially outwardly of said nozzle for applying a force to the outer peripheral edges of said disk to clamp and seal said disk between said seal means and said means for supporting said disk, elongated duct means extending between said suction nozzle and said body closure assembly duct means, a motor-fan unit mounted within said motor housing assembly for drawing an air stream through said suction nozzle, said elongated duct means, said body closure assembly duct and said air filter means to remove dust and dirt particles from said airstream, an elongated handle assembly, means supported by said bulkhead assembly for releasably receiving therein the lowermost end portion of said handle assembly, said handle assembly further including means for retaining said body closure assembly in a closed position.

Abstract
A lightweight, upright, top-loading vacuum cleaner wherein a seal between the disk of a filter bag and a duct for conveying dirt-laden air to the bag is provided adjacent the outer peripheral edges of the disk resulting in the disk becoming an integral part of the seal while eliminating pressure differential across opposite sides of the disk. A portion of the duct extending into the filter bag is capable of being displaced to an open position for filter bag loading and unloading and is normally closed to maintain the seal by a latch which cooperates with the handle vacuum cleaner handle. The vacuum cleaner handle includes electrical components having projections which are releasably received and supported within an electrical receptacle supported by the vacuum cleaner housing.
