ABSTRACT:
A glass refrigerator door structure constructed with two or more glass panels and having a peripheral door frame extending around the sides of the door structure and at the inside of the door without covering the outside glass surface of the door. Sealant is used to bond the glass panels to peripheral spacers separating the panels and to pipe-like structures which extend peripherally around the sides of the door structure. The door frame is connected to the pipe-like structures by a peripheral extension from the frame which engages elongated slots in the pipe-like structures. As such, mechanical fasteners such as nuts, bolts or screws are not needed for the purpose of holding the refrigerator door structure together.
