MECHANISMS FOR OPENABLE/CLOSEABLE MEANS ABSTRACT OF THE DISCLOSURE This invention relates to a mechanism or hinge for use in a structural glass assembly. In particular the mechanism is attachable to a glass unit, e.g. a double glazing unit, to enable it to open or close. The mechanism has essentially two parts, a stationary part and a movable part. The stationary part which is attachable to the glass structure incorporates two blade-like plates between which the movable part is slideably located. The stationary part has two arcuate tracks (open and closed) over which a pair of roller bearings are guided during operation of the mechanism whereas the movable part which is attachable to e.g. a double glazed unit, has a single arcuate track over which a single roller bearing is guided during operation of the mechanism. The mechanism has a virtual pivot point on the glazing unit to which the mechanism is attachable. One embodiment of the invention includes a centring arrangement Figure 5 where a pair of tapered roller bearings are guided on arcuate tapered surfaces of a closed track.
