Abstract

A sealed double glazing unit having an outer pane with a countersunk hole punched in a corner thereof, and an inner pane with a hole punched in a corner thereof, opposed to the countersunk hole in the outer pane. A generally cylindrical liner is inserted into the countersunk hole in the outer pane, a bottom of the liner extending into, without passing through, the countersunk hole in the outer pane. A glazing unit is secured to a supporting member by a fixing member which is fixed through the liner, and a sealing member engages the holes in the inner and outer panes. This sealing member includes a guide ring having the same diameter as the diameter of the bottom of the liner, with a front end of the guide ring extending into the countersunk hole and abutting against the bottom of the liner. The sealing member also includes a ring-shaped boss concentric with and encircling the guide ring, the ring-shaped boss having an inner diameter that is larger than an outer diameter of the guide ring such that a space is formed between the guide ring and the boss. This space is bridged by a plurality of connecting parts extending between the outer diameter of the guide ring and the inner diameter of the ring-shaped boss.
