  • Patent number: 4106476
    Abstract: This door omits the usual metal frame for supporting a pane of glass. Hinges are mounted on channel trim strips on the adjacent edges of a pair of the glass panes to provide a two panel folding door. The lower hinge has a spring catch to hold the door closed. The trim strips are secured in assembled relation on the horizontal and vertical edges of the glass by snap fit engagement with four corner connectors within the channels, without screws or welds. On one of the panels two of the corner connectors have pivot posts for mounting the door in a stationary frame and on the other panel two of the corner connectors have guide posts which slide in grooves in said frame. Thus the trim strips and corner connectors themselves form a frame for the glass in each door panel.
