The door comprises a leaf essentially of glass, the glass constituting the structure of the leaf. It is advisable to distinguish clearly this door of glass from a glazed door of wood. In the door of glass as in the conventional glass doors, the structure of the leaf is constituted of the glass, the glass occupying, in effect, the greater part of the leaf, assuring the rigidity and strength of said leaf and not being supported by any element of a different material or not being carried by any frame.The presence of an upright member of a material other than glass, in the glass door, does not in any way change the structure, the aforementioned upright simply extending the glass laterally and not having the function of supporting the glass in its lower part when the glass is in a vertical position or of assuring stiffening of the leaf. In glazed doors of wood, the glass occupies a more limited proportion of the leaf and is supported by reinforcements and/or frames of timber, the reinforcements and frames forming the structure of the leaf.
