Abstract
Abstract An upright vacuum cleaner conversion and storage pedestal for receiving and supporting a vacuum cleaner and adapting the cleaner to flexible hose cleaning tasks is disclosed having a wheeled base or bed releasably fastenable to the bottom of the cleaner with a vacuum transmitting conduit in the base positionable in substantially airtight relation with the suction mouth of the cleaner and communicating with a coupler for joining a flexible air hose to the conduit so that the pedestal supported cleaner may be used in much the same manner as a conventional canister type cleaner. A leg may be pivotably supported beneath the base, movable between a stowed horizontal position and an extended position for supporting the cleaner and pedestal on a stairway with wheels of the base resting on one step surface and the leg resting on the next lower step surface so as to adapt the upright vacuum cleaner to vacuuming stairways and the like. The pedestal or base may extend laterally beyond a supported cleaner and include attachment arrangements for supporting cleaner accessories. A quick release cam arrangement may be provided for securing the cleaner to the pedestal. A method of adapting an upright vacuum cleaner for vacuuming stairways is also disclosed.

Claims Analysis
Total Claims: 14
Claim 1
Independent Claim
182 words
A mobile adapter pedestal and accessory caddy for an upright vacuum cleaner comprising: a cleaner supporting bed having a plurality of depressions for accepting cleaner wheels, an opening for fitting snugly adjacent the suction mouth of the cleaner when the cleaner is supported in position on the bed, a coupler for receiving a flexible air hose, and a conduit leading from the opening to the coupler to transmit suction from the cleaner to a flexible air hose; a plurality of wheels beneath the bed for rollably supporting the bed; means for securing a cleaner in position on the bed with the cleaner wheels in the bed depressions and the cleaner suction mouth juxtaposed with the opening; and a generally U-shaped leg pivotably supported beneath the bed and movable between a stowed position lying generally flat against the bottom of the bed in a generally horizontal attitude and an extended position to support the bed and associated cleaner on a stairway with some of the plurality of wheels resting on one step surface and the leg resting on the next lower step surface.
Claim 2
Dependent Claim

Claim 3
Dependent Claim
20 words
The device of claim 1 wherein at least some of the set of wheels beneath the bed are caster wheels.
Claim 4
Dependent Claim
34 words
The device of claim 1 wherein the U-shaped leg is pivotably attached to the underside of the bed near the U ends and further comprising means yieldably retaining the leg in the stowed position.
Claim 5
Dependent Claim
118 words
A traylike upright vacuum cleaner conversion and storage pedestal for receiving and supporting a cleaner and adapting the cleaner to flexible hose cleaning tasks comprising a wheeled base releasably fastenable to the bottom of the cleaner, a vacuum transmitting conduit in the base adapted to be placed in substantially air-tight relation with the suction mouth of the cleaner, a coupler for joining a flexible air hose to the conduit, and a leg pivotably supported beneath the base and movable between a stowed generally horizontal position and an extended position to support a cleaner and the pedestal on a stairway with certain base wheels resting on one step surface and the leg resting on the next lower step surface.
Claim 6
Dependent Claim
118 words
A traylike upright vacuum cleaner conversion and storage pedestal for receiving and supporting a cleaner and adapting the cleaner to flexible hose cleaning tasks comprising a wheeled base releasably fastenable to the bottom of the cleaner, a vacuum transmitting conduit in the base adapted to be placed in substantially air-tight relation with the suction mouth of the cleaner, a coupler for joining a flexible air hose to the conduit, and a leg pivotably supported beneath the base and movable between a stowed generally horizontal position and an extended position to support a cleaner and the pedestal on a stairway with certain base wheels resting on one step surface and the leg resting on the next lower step surface.
Claim 7
Dependent Claim
36 words
The pedestal of claim 4 wherein the leg is generally U-shaped and pivotably attached to the underside of the base near the U ends and further comprising means yieldably retaining the leg in the stowed position.
Claim 8
Dependent Claim
25 words
The pedestal of claim 4 wherein the base extends laterally beyond a supported cleaner, the laterally extending base portion including means for supporting cleaner accessories.
Claim 9
Independent Claim
113 words
The method of adapting an upright vacuum cleaner for vacuuming stairways comprising the steps of: extending a normally horizontally stowed leg to a generally vertical direction; partially supporting the cleaner on a step surface with a portion of the cleaner overhanging the step surface and the leg extending downwardly from that overhanging portion to engage and partially support the cleaner on the next lower step surface; coupling a flexible air transmitting hose to a cleaner suction inlet and a cleaning accessory to the hose end remote from the cleaner suction inlet; and vacuuming a plurality of steps before moving the cleaner to a position supported on a different pair of adjacent step surfaces.
