Abstract
Frames for mounting windows within the walls of enclosures for isolating or sealing substances such as radioactive or other hazardous substances from the surrounding environment. In a first embodiment of the present invention, a window assembly includes a two-piece frame that is welded into the wall of an enclosure. In a second embodiment of the present invention, a window assembly includes a three-piece frame that is clamped to the wall of an enclosure. The frame assemblies may also be used to mount structures other than windows to enclosure walls, such as ducts or pipes intended for passing power, gas, vacuum, or other utilities into the interior of an enclosure.
Claims8
A system, comprising:
- an enclosure having a non-glass wall;
- a first frame member having a ledge surrounding a central opening in the first frame member and a raised portion extending perpendicular to and surrounding the ledge;
- a lip formed in the first frame member around an outer edge of the raised portion, the lip having a first surface abutting against an inside surface of the non-glass wall and a second surface lying within an inside periphery of an aperture passing through the non-glass wall;
- a plurality of fastener-receiving holes formed in a mounting surface on the raised portion of the first frame member;
- a second frame member having a mounting surface and an opposing clamping surface surrounding a central opening in the second frame member, wherein the clamping surface of the second frame member abuts against an untapped region of an outside surface of the non-glass wall;
- a plurality of holes extending through the second frame member, wherein the plurality of holes extending through the second frame member is spaced for alignment with the plurality of fastener-receiving holes in the first frame member;
- a third frame member having a clamping surface surrounding a central opening in the third frame member, wherein the clamping surface of the third frame member is adapted to abut against the mounting surface of the second frame member and overlie the ledge of the first frame member;
- and
- a plurality of holes extending through the third frame member, wherein the plurality of holes extending through the third frame member is spaced for alignment with the plurality of fastener-receiving holes in the first frame member.
