Appl. No.:

7/088007

Inventors:

Ronald R. Pohl - Rochester MI

Assignee:

Venderbush Industrial Corporation - Mt. Clemens MI

International Classification:

E04H 1534

Abstract:

A controlled environment enclosure provides a dust-free atmosphere for manufacturing operations. The enclosure includes a frame formed of interconnected, horizontally and vertically extending, spaced frame members. An outer cover member is deployed over the sides and top of the interconnected frame members. The outer cover member is formed of a heat shrinkable material which provides a taut, secure attachment of the cover member to the frame members. The bottom ends of the cover member are sealingly attached to a lower support surface or floor by means of an interconnectable clamp and strip having a mating projection and notch which traps the bottom end of the cover member therebetween.

Abstract:

A contaminant shield prevents airborne contaminants from contacting manufactured parts in a work area in a manufacturing facility. The contaminant shield is formed of a plurality of like frames, each formed of a plurality of interconnected side frame members covered by a flexible sheet attached at its outer edges to the side frame members. The frames are interconnected at adjacent edges to form the complete contaminant shield. A sealing strip is applied to the joints between adjacent frames to form a continuous contaminant barrier in conjunction with the flexible sheet attached to each frame. The contaminant shield is constructed by first constructing a plurality of frames by interconnecting side frame members into a rigid, planar frame and attaching the edges of a flexible sheet to each side frame member of the frame. Each of the side frame members includes an aperture which receives a complimentrally shaped cap which traps the edges of the flexible sheet between itself and the aperture in the side frame for securely attaching the flexible sheet to the side frame.
