`ABSTRACT
`
`The present disclosure provides a portable backpack vacuum
`cleaner, carried on the back of the operator, by the means of
`shoulder and belt straps. The vacuum hose through which
`dirt is collected
`is connected
`to the vacuum unit at the
`bottom of the unit, providing
`for superior motor perfor-
`mance. Furthermore,
`the present disclosure operates without
`for storing
`further
`incoming
`paper bags
`the
`dirt,
`thus
`and economy of the unit.

`
`FIELD OF THE INVENTION
`[0001] The present
`relates to vacuum cleaners,
`invention
`to portable vacuum cleaners, which are
`more particularly
`free movement of
`carried on the operator's back, allowing
`the operator's hands for greater accessibility of areas to be
`cleaned.
`
`BACKGROUNDART
`
`[0002] The earliest vacuum
`floor-based
`cleaners were
`models, with dust receptacle canister being dragged by the
`facilitated by the wheels mounted
`to the
`operator,
`typically
`bottom of the vacuum cleaner. The major disadvantage of
`such models was the inconvenience of reaching elevated or
`to be cleaned
`(such as tight corners,
`cumbersome
`areas
`stairways, shelves).
`[0003]
`to this drawback, portable vacuum
`In response
`to be carried by the operator, either
`cleaners were designed
`as "back pack" vacuums,
`shoulder-mounted
`vacuums, and
`to be
`vacuums. These models were
`belt-mounted
`found
`in cleaning heavily congested areas in various com-
`useful
`mercial settings, such as olfice areas, hotels,
`theaters, and
`restaurants.
`
`[0004] The conventional backpack vacuum cleaners avail-
`inlet vacuum hose
`able on
`the market
`today have
`the
`to the top of the machine. The air moves from the
`attached
`the top of the unit to the bottom vent port. This
`hose through
`special motor protection
`to keep
`design
`requires
`system
`objects from damaging
`fans. This protection
`the suction
`is usually a heavy-duty material
`that also serves as
`system
`the vacuum bag retainer. This system provides for effective
`motor protection, but compromises
`system performance,
`the unit increases as the pores in
`since the resistance
`through
`the retainer bag are impregnated with dust particles, and the
`vacuum bag starts to fill. This increased resistance will cause
`a decrease in overall machine performance.
`[0005] The details of the conventional back-pack vacuum
`in U. S. Pat. Nos. 5, 588, 177;
`cleaner design are set forth

`disclosure of which is incorporated by reference.
`[0006] The present invention overcomes the shortcomings
`of the prior art by providing
`a portable vacuum unit with
`and ease of maintenance. Conven-
`superior performance
`tional backpack vacuum cleaners have inlet hoses attached
`to the top of the housing, with the air moving from the top
`to the bottom vent port. This design requires special heavy-
`duty motor protection system to keep objects from damaging
`the suction fans. This increased weight and resistance com-
`for the added
`promises system performance. To compensate
`weight, most conventional backpack units use an injected
`is less
`molded plastic housing. Such housing, however,

`
`SUMMARY OF THE INVENTION
`
`It is an object of the present
`[0007]
`to provide a
`invention
`in shape, of
`portable back pack vacuum cleaner, cylindrical
`is carried on the back of the
`the type in which
`the vacuum
`operator, by the means of shoulder
`and belt straps. The
`
`vacuum hose, which collects dirt is connected to the vacuum
`the bottom of the unit. The hose
`is
`unit 6 inches
`from
`to the unit tangentially. The cleaner operates with-
`attached
`out a paper bag.
`[0008] Other objects of the present
`invention will in part
`be obvious and will in part become apparent
`to those skilled
`in con-
`the following detailed description
`in the art from
`junction with the accompanying drawings.

`main vacuum body 9 is made from 6" dia. PVC pipe. The 8'
`pipe is cut into four 22" sections. Each section is sanded
`to
`remove cutting burs. After sanding, each section is cleaned
`with Isopropyl Alcohol to remove all blemishes and manu-
`facturer's
`identification marks. All component penetrations
`in FIGS. 1
`and attachment holes are drilled as indicated

`
`[0021] FIG. 3 indicates the location and dimensions of the
`the back harness 8 to the main
`holes needed
`to attach
`vacuum body 9. The harness will be mounted
`to the vacuum
`after the motor 5 has been installed per FIG. 8.
`[0022] FIG. 4 indicates
`the electrical connection detail.
`The cord assembly 1, 2 is connected
`to the motor 5 wires
`in this detail. The cord retainer
`using the schematic shown
`to the housing 9. The location
`3 fastens the cord assembly
`and dimensions of the hole needed for the cord retainer were
`in FIG. 2.
`shown
`[0023] FIG. 5 indicates the top cover of the unit, which is
`made from 6" diameter PVC pipe cap 10. The top cover has
`six 1" symmetrically
`located holes to permit
`the discharged
`air to exit the unit with minimum motor backpressure. The
`cover has a stop ring 41 to permit adequate ventilation space
`the motor and cover. The stop rings are sections of
`between
`6" PVC pipe cut to fit required width.
`[0024] FIG. 5 also shows the vacuum
`transport handle 33,
`two 10-24x1'/z"
`is attached
`to the top cover with
`which
`Phillips head screws and two lock washers and lock nuts to
`fit attachment screws. A cap filter 13 is glued to under side
`to keep debris out of the motor
`of cap. This filter is required
`compartment. The cap is attached
`to the vacuum housing
`with three 10-24x'/4" self tapping screws.
`[0025] FIG. 6 indicates
`the bottom dirt receptacle of the
`unit, which is also made from 6" diameter PVC pipe cap 10.
`The bottom receptacle uses a '/z" spacer 41 to limit insertion
`and provide a seal between
`the vacuum housing and bottom
`cap. Two '/4" x1/i" eyebolts 19 are inserted
`into the bottom
`in FIG. 6. Two bungee cords 22 are attached
`cap as shown
`to the vacuum housing. The free ends of the bungee cords
`have spring clips 23. The bottom cap is attached
`to the
`the spring clips 23 and the
`vacuum housing by connecting
`eyebolts 19.
`[0026] The hose fitting 11 is positioned over the inlet hole
`penetration and is oriented so that it is parallel to the bottom
`in FIG. 7. The fitting is
`of the vacuum housing, as shown
`to the housing with four '/z" long 16-20 screws and
`attached
`lock nuts 39. After both parts are secured, an epoxy 18 is
`the hose fitting 11 and
`to fill all void areas between
`applied
`the vacuum housing 9. This epoxy provides an airtight seal
`and forms a structural bond between both parts. The unit is
`then lightly sanded and is sprayed with one primer coat and
`two finish coats of Rustoleum enamel.
`[0027] FIG. 8 indicates the detail of the attachment of the
`motor 5 to the vacuum housing 9. The motor housing
`is
`for the 10-16x'/z" screws. Three Stanley 1 "x1 "x
`pre-drilled
`to the Lamb motor 5
`'/4" pre drilled angles are attached
`(model no. 116146. 000), using a 10-16x'/z" self-tapping
`'/4" x1/i" is used to
`screws. A foam rubber seal 40 measuring
`provide the seal between the vacuum housing and the motor.
`The motor filter dome
`is placed over the motor and
`the
`
`is placed in the housing using a 10-24x'/4" Phillips
`assembly

`motor mounts were shown
`[0028] FIG. 9 shows
`the assembly of hose and wand
`components. The hose 12 and the wand 7 are assembled and
`inlet hose fitting 11. The connec-
`test fitted into the vacuum
`tion between these two assemblies forms a seal between
`the
`vacuum housing and the hose assembly. This test fit-up is
`to ensure that the seal between these parts were not
`required
`the painting operation. A light sanding
`compromised during
`of mating parts may be required
`to obtain desired seal.
`[0029] After the motor is attached to the housing,
`the filter
`assembly 13 is fastened
`to the housing using a 10-24x'/4"
`Phillips head screw with lock washer and nut. The location
`and dimensions of the holes needed for the filter assembly
