Abstract

Abstract There is disclosed herein a cart for computer cleaning. The cart includes a wheeled housing which defines a housing and a work surface at the top end of the frame. The housing includes a rear compartment in which a compressed gas unit, a retractable hose reel, a vacuum, and a retractable power cord are mounted. In addition, the housing includes an openable front compartment in which various tools are carried at convenient locations. The top of the cart carries a foldable work surface which may be folded to an open position wherein the computer components can be laid on the work surface. The frame defines a bottom well within which the hose reel may be partially positioned so as to lower the center of gravity and afford the cart with enhanced stability and reduce tipping susceptibility.

Claim 1
Independent Claim 161 words
A portable cart for use in cleaning computer systems at remote locations which includes: a housing mounted on wheels for movability wherein said housing includes a rear compartment and a front compartment, said rear compartment storing vacuum means, compressed gas means and compressed gas distribution hose means associated with the compressed gas means and an electric power means; said compressed gas means being stored on one side of the housing, said vacuum means being stored on the other side of said housing; said compressed gas distribution hose means including a reel on which said hose means is stored positioned between the compressed gas means and vacuum means, said hose being extendable from said reel; said housing having a floor and said floor defining a well therein which is aligned with the hose reel and at least a portion of the hose reel fits into the well so as to minimize the height of the hose reel relative to a support surface.
Claim 2
Dependent Claim 161 words
A portable cart for use in cleaning computer systems at remote locations which includes: a housing mounted on wheels for movability wherein said housing includes a rear compartment and a front compartment, said rear compartment storing vacuum means, compressed gas means and compressed gas distribution hose means associated with the compressed gas means and an electric power means; said compressed gas means being stored on one side of the housing, said vacuum means being stored on the other side of said housing; said compressed gas distribution hose means including a reel on which said hose means is stored positioned between the compressed gas means and vacuum means, said hose being extendable from said reel; said housing having a floor and said floor defining a well therein which is aligned with the hose reel and at least a portion of the hose reel fits into the well so as to minimize the height of the hose reel relative to a support surface.
Claim 3
Dependent Claim 258 words
A portable cart for use in cleaning computer systems at remote locations which includes: a housing, mounted on wheels for movability on a support surface wherein said housing includes a rear compartment and a front compartment, said rear compartment storing vacuum means, compressed gas means, and compressed gas distribution hose means associated with the compressed gas means, electric power means and having in a side thereof a vacuum outlet connected to said vacuum means; a front compartment adjacent the rear compartment being openable and constructed to carry tools for cleaning a computer; electric cord means associated with said power means, hose means associated with said compressed gas means and extendable into a front compartment; an openable work surface on the top of the rear compartment and foldable rearwardly to an open position; a handle associated with the rear compartment for moving of the cart and constructed to support the openable top; wherein said compressed gas is stored in a bottle in the rear compartment on one side thereof, said vacuum means is stored on the other side of said rear compartment and said compressed gas hose means is stored on reel positioned between the bottle of gas and vacuum, and said hose being extendable from said reel; and wherein said cart includes a floor portion having a well or lower portion therein, which well is aligned with the hose reel and at least a portion of the hose reel fits into the well so as to minimize the height of the hose reel relative to a support surface.
Claim 4
Dependent Claim 258 words
A portable cart for use in cleaning computer systems at remote locations which includes: a housing, mounted on wheels for movability on a support surface wherein said housing includes a rear compartment and a front compartment, said rear compartment storing vacuum means, compressed gas means, and compressed gas distribution hose means associated with the compressed gas means, electric power means and having in a side thereof a vacuum outlet connected to said vacuum means; a front compartment adjacent the rear compartment being openable and constructed to carry tools for cleaning a computer; electric cord means associated with said power means, hose means associated with said compressed gas means and extendable into a front compartment; an openable work surface on the top of the rear compartment and foldable rearwardly to an open position; a handle associated with the rear compartment for moving of the cart and constructed to support the openable top; wherein said compressed gas is stored in a bottle in the rear compartment on one side thereof, said vacuum means is stored on the other side of said rear compartment and said compressed gas hose means is stored on reel positioned between the bottle of gas and vacuum, and said hose being extendable from said reel; and wherein said cart includes a floor portion having a well or lower portion therein, which well is aligned with the hose reel and at least a portion of the hose reel fits into the well so as to minimize the height of the hose reel relative to a support surface.
Claim 5
Dependent Claim 44 words
A portable cart as in claim 2, wherein said rear compartment is accessible by a pair of doors in the rear thereof and insulation is applied to the interior of the rear compartment for minimizing sound transmitted from the compartment to positions external thereof.
