Abstract
Abstract A paint spray booth enclosure having fixed, outer walls and movable, inner walls. Many inner walls throughout the length of a paint spray booth enclosure could be placed such that the total air volume moving through the work stations inside the paint spray booth enclosure would be minimized, thus lowering energy costs and capital investment for related equipment.

Total Claims: 12
Claim 1
Independent Claim
54 words
An improved paint spray booth enclosure of the type having controlled air flow through a perforated ceiling and a perforated floor, wherein the improvement comprises: outer walls; a plurality of movable inner walls located interiorly of the outer walls; and means for blocking controlled air flow between the inner walls and the outer walls.
Claim 2
Dependent Claim
54 words

Claim 3
Dependent Claim
55 words
The booth of claim 1 wherein the inner walls may be positioned at various distances from the outer walls to suit the desired work space needed at each work station in the booth such that each work station in the booth may have a unique width with respect to other work stations in the booth.
Claim 4
Dependent Claim
24 words
The booth of claim 1 wherein the inner walls are made in sections, of sizes and weights which are capable of being manually moved.
Claim 5
Dependent Claim
24 words
The booth of claim 2 wherein the inner walls are made in sections, of sizes and weights which are capable of being manually moved.
Claim 6
Dependent Claim
46 words
The booth of claim 1 wherein said means for blocking controlled air flow comprises barrier plates positioned over portions of the perforated ceiling overlying the spaces between the inner walls and the outer walls such that controlled air flow may be greatly reduced in said spaces.
Claim 7
Dependent Claim
113 words
An improved paint spray booth enclosure of the type having a plurality of work stations and controlled air flow through a perforated ceiling and a perforated floor wherein the improvement comprises: outer walls; a plurality of movable, inner walls located interiorly of the outer walls for minimizing the controlled air space in the booth by positioning the inner walls at various distances from the outer walls to define a desired work space needed at each work station in the booth; and barrier plates positioned over portions of the perforated ceiling overlying the spaces between the inner walls and the outer walls such that controlled air flow may be greatly reduced in said spaces.
Claim 8
Dependent Claim
113 words
An improved paint spray booth enclosure of the type having a plurality of work stations and controlled air flow through a perforated ceiling and a perforated floor wherein the improvement comprises: outer walls; a plurality of movable, inner walls located interiorly of the outer walls for minimizing the controlled air space in the booth by positioning the inner walls at various distances from the outer walls to define a desired work space needed at each work station in the booth; and barrier plates positioned over portions of the perforated ceiling overlying the spaces between the inner walls and the outer walls such that controlled air flow may be greatly reduced in said spaces.
Claim 9
Dependent Claim
148 words
An improved paint spray booth enclosure of the type having a plurality of work stations, fixed, outer walls, and controlled air flow through a perforated ceiling and a perforated floor, wherein the improvement comprises: movable, inner walls for minimizing the controlled air space in the booth; the inner walls positioned at various distances from the outer walls to define a desired work space at each work station in the booth; the inner walls made in sections of sizes and weights which are capable of being manually moved; barrier plates positioned on the perforated ceiling in the space between the outer walls and the inner walls thereby greatly reducing controlled air flow through the ceiling in said space; first means for removably coupling a top portion of each inner wall to the ceiling; and second means for removably coupling a bottom portion of each inner wall to the floor.
Claim 10
Dependent Claim
148 words
An improved paint spray booth enclosure of the type having a plurality of work stations, fixed, outer walls, and controlled air flow through a perforated ceiling and a perforated floor, wherein the improvement comprises: movable, inner walls for minimizing the controlled air space in the booth; the inner walls positioned at various distances from the outer walls to define a desired work space at each work station in the booth; the inner walls made in sections of sizes and weights which are capable of being manually moved; barrier plates positioned on the perforated ceiling in the space between the outer walls and the inner walls thereby greatly reducing controlled air flow through the ceiling in said space; first means for removably coupling a top portion of each inner wall to the ceiling; and second means for removably coupling a bottom portion of each inner wall to the floor.
Claim 11
Dependent Claim
32 words
The booth of claim 7 wherein the first means for removably coupling comprises a bracket assembly bolted to the inner wall and designed to hang from existing structural members in the ceiling.
Claim 12
Dependent Claim
