Abstract:
In an abrasive blasting system including an abrading device for delivering a spray of abrasive particles in the direction of an article to be abraded, a collapsible spray cabinet for containing said abrading device and said abraded article, comprising:a flexible cabinet housing having an expanded position for defining an interior blasting chamber and a collapsed position for storage, said housing including a bottom, a plurality of sidewalls and a top, where the combination defines said interior blasting chamber, at least one of said sidewalls having a cover member which may be opened to allow the placement of said article to be abraded through said sidewall into said blasting chamber;a folding frame supporting said cabinet housing and having an open position wherein said cabinet housing is held in said expanded position and a closed position wherein said cabinet housing is held in said collapsed position, said folding frame including a base, a plurality of vertically disposed support members, a plurality of horizontal loading members, and a plurality of spacing members, said spacing members being secured to said supporting members and pivotally connected to said loading members so as to allow said loading members to pivot to form a substantially flat unit when said folding frame is in said closed position;means for suspending said cabinet housing from said loading members of said folding frame;a support element disposed in a spaced relationship to said bottom and said top for supporting said article to be abraded when said cabinet housing is in said expanded position;access means for manipulating said abrading device from a position exterior to said cabinet housing;a transparent viewing portal disposed in one of said sidewalls for allowing an operator to view the interior of the cabinet housing;said bottom having a funnel shape for collecting spent abrasive particles;an exhaust port disposed in one of said sidewalls for connecting to a source of vacuum; andmeans for providing the ingress of ambient air into said blasting chamber so as to establish a continuing current of air flow downwardly through said support element and through said exhaust port, whereby said current of air continuously clears said blasting chamber between said viewing portal and said support member.
