  • Window frame system for vacuum insulated glass unit
    Patent number: 9845635
    Abstract: A window assembly may include a vacuum insulated glass unit and a frame assembly. The vacuum insulated glass unit may include first and second glass substrates defining a space therebetween that is at a pressure lower than atmospheric pressure. One of the first and second glass substrates may include a vacuum port extending outward therefrom. The vacuum port may define a passage in communication with the space. The frame assembly supports the glass unit and may include a base member and a glazing member. The base member and the glazing member cooperate to define a slot in which an edge portion of the glass unit is received. The glazing member may include a cavity receiving the vacuum port.
    Type: Grant
    Filed: September 19, 2016
    Date of Patent: December 19, 2017
    Assignee: Guardian Glass, LLC.
    Inventors: Robert D. Thompson, Charles L. Anderson, John M. Mitchell, Nigel J. Flynn, Kunal D. MacDonald, David Scott Rowley, Edward I. Stamm, Jr.
