Temporary portable abatement, remediation, demolition, and remodeling door

摘要

A reusable and portable temporary door/frame assembly primarily used in abatement, remediation, demolition, and remodeling applications with a containment enclosure or barrier to allow quick and easy ingress/egress, or restrict movement, to/from a limited access area. The assembly comprises lightweight materials, such as but not limited to plastic or aluminum, and two non-spring-loaded telescopic poles that extend a top bar/piece upwardly for attachment to an overhead door frame, header, or ceiling. The top of the frame is also configured to accept two upwardly extendable spring-loaded/biased poles allowing a containment enclosure or barrier to be built to ceiling heights beyond the reach of the integral telescopic poles. Since the assembly is portable, it can be installed to open inwardly, outwardly, and is reversible, depending on convenience or need. The door is lockable. The door panel's frame includes a seal at the top/bottom to reduce air transmission to/from the limited access area.

主权项

1. A reusable, portable, and reversible temporary door and frame assembly blocking unauthorized access into construction areas and primarily used in abatement, remediation, demolition, and remodeling applications with an underneath supporting surface, an overhead surface, and a walkway opening leading to a construction area, said door and frame assembly comprising:
an outer frame portion having a top end, opposing sides, and a bottom end; a door with an upper end and an opposed lower end, said door also having hinged connection to one of said opposing sides of said outer frame portion allowing movement of said door relative to said outer frame portion between a closed position against said outer frame portion and opened positions creating a temporary walkway access through and between said top end, said opposing sides, and said bottom end of said outer frame portion; a generally C-shaped top extension having two non-spring-loaded poles each with a top end and an opposed bottom end, said top extension also having a top bar connected across and between said top ends of said two poles, said bottom ends of said poles associated with said outer frame portion for repeat upward and downward elevation change of said top bar toward and away from said outer frame portion wherein differing portions of said poles remain hidden from view within said outer frame portion; and a door handle allowing on-demand movement of said door between said closed position against said outer frame portion and at least one of said opened positions, wherein when said temporary door and frame assembly is positioned in front of said walkway opening leading to said construction area, said bottom end of said outer frame portion is temporarily secured to a supporting surface in a manner eliminating air transmission around said bottom end, said top bar of said top extension is temporarily secured to an overhead surface in a manner eliminating air transmission around said top bar, and said opposing sides are temporarily secured to eliminate air transmission around them, said door and frame assembly can provide containment of potentially harmful substances within, and block unauthorized access to, the construction area, and after association with said walkway opening leading to said construction area, said assembly can be promptly and easily relocated for reuse.
