摘要： A vacuum hose storage system includes a housing which is mounted in a storage area of a dwelling or vehicle and connected to a vacuum source. A length of flexible, expandable cleaning hose is mounted in a looped fashion about a plurality of spaced rollers rotatably mounted within the housing. A handle is attached to one end of the hose and is seated in a cradle formed in the housing when the hose is in a fully retracted position within the housing. The cradle is mounted in the housing and receives the open end of the hose when not in use and enables other vacuum tubes in t he structure to be operational without shutting off the vacuum to the stored hose. An ON/OFF switch is located in the cradle for controlling the vacuum source and is actuated when the handle is placed in or removed from the cradle. The hose h as an internal helical spring which biases the hose toward a retracted position about the spaced rollers within the housing. In an alternate embodiment, the hose is slidably extendable from within a rigid serpentine tubing mounting within the housing .

摘要： A mounting bracket for use in association with a vacuum canister for a central vacuum system is disclosed. The mounting bracket is received within the housing of the vacuum canister and thereby divides the canister into clean a nd dirt collection chambers. Dirt collection chamber is adapted to receive dirt - laden air from the central vacuum system while clean chamber is adapted to re- circulate cleaned air back into the building. Mounting bracket is preferably a molded structure having a central bore. A plurality of stepped grooves are provided for receiving one of a variety of sizes of motor therein. A plurali ty of circuit board brackets are formed on mounting bracket, said circuit board brackets range in size so as to accommodate a range of sizes of circuit boar ds therein. Mounting bracket further includes a filter support formed therein. The fitter support includes a quick attachment/release mechanism for installing filters thereon. Mounting bracket also includes art aperture and straight tube connection for connecting a clean chamber auxiliary intake valve assembly to the dirt collection chamber of the vacuum canister.

摘要： A vacuum canister for use with a central vacuum system is disclosed. The vacuum canister includes a hollow, tubular housing that has openings at eith er end. A cover covers the upper opening and a dust collection bin is disposed beneath the lower opening. The housing is divided into clean and dirt collection chambers by a wall. The clean chamber is a dust-free area and the vacuum pump assembly is mounted therein. The dirt collection chamber is the area in the canister where the dirt-laden vacuumed air is drawn into the device. The vacuum canister is provided with an auxiliary vacuum intake assembly that enters the housing in the clean, dust-free chamber. The intake assembly includes a receptacle for receiving the end fitting of a portable vacuum hos e and the receptacle is operatively connected to the dirt collection chamber of th e housing by way of a conduit that extends from the receptacle through an aperture in the wall and into the dirt collecting chamber. The receptacle is wired to the motor for the vacuum pump assembly so that when the portable hose is attached to the receptacle, the vacuum pump is automatically started. The wiring for the receptacle passes through the clean chamber of the housing. The receptacle includes a pivoted cover which covers the receptacle when it is n ot in use so as to maintain the vacuum within the system.
