  • Patent number: 4525966
    Abstract: A window construction incorporates a pane or panes of glass retained in a frame by glazing beads inserted between the glass and the frame at the outside of the window and incorporates means for preventing disengagement of the glazing beads other than by breaking the glass. The glazing beads may incorporate oppositely acting retaining formations engageable with at least one co-operating retaining member on the frame, each retaining formation being arranged to be more firmly engaged by movement of the associated bead in a direction to disengage the other formation. In an alternative arrangement the glazing beads may incorporate retaining formations which extend beyond and are retained by the edges of the glass following completion of the glazing process.
