Claims Analysis

Total Claims: 3
Claim 1
Independent Claim 351 words
A paint spray filter for use in a paint spray booth characterized by a pair of substantially parallel side panels, an end panel interconnecting said side panels, a top panel overlying said side panels and said end panel, means defining access to said booth from the front of said booth, and frame means disposed intermediate said end panel and said access, comprising: a grid comprising a plurality of parallel vertical members including a first pair of said vertical members defining the vertical edges of said grid and being substantially twenty-four inches apart, and a second pair of said vertical members being located substantially twelve inches apart and substantially six inches from respective ones of said first pair of said vertical members; a plurality of parallel horizontal members including a first pair of said horizontal members defining the horizontal edges of said grid, and being substantially thirty-six inches apart, and a second pair of said horizontal members being located substantially eighteen inches apart and substantially six inches from respective ones of said first pair of said vertical members, and another one of said horizontal members located substantially midway between said second pair of said horizontal members; a plurality of attachment spikes secured to said grid, extending outwardly and upwardly therefrom, four of said spikes being located at the intersections of said second pair of said vertical members and said second pair of horizontal members, and two of said spikes being located at the intersections of said second pair of said vertical members and said other one of said horizontal members; a sheet of fiberglass filter material having a first face substantially covering said grid and being secured thereto by said attachment spikes, and a fully exposed second face; and support means extending from the corners of said grid and adapted to cooperate with said frame means of said booth for maintaining said paint spray filter in said booth, whereby said paint spray filter defines a barrier separating said booth into an exhaust area located between said barrier and said end panel, and a spraying area located between said barrier and said access.
