Mechanism for sliding glass doors

A mechanism for mounting a sliding glass door, comprising:

• an upper track,
• a lower guide parallel to the upper track,
• suspension heads fixed to an upper edge of the door and provided with bearing elements that can be moved along the upper track, and
• means for limiting movement of the door,
• wherein the upper track comprises an inverted L-shape, a vertical member of which is provided on its internal surface with means for fastening travel stops which restrict horizontal travel of the door, the vertical member ending, along its free edge, in an inverted groove which protrudes towards the internal surface of the vertical member, the groove being provided externally with a longitudinal rib with a rounded profile, a horizontal member of the L-shape being provided with a central external channel with through holes, and a slit along its free edge for securing a vertical lifting stop, the function of which is to restrict lifting of the door, and
• wherein the suspension heads comprise two approximately equal rectangular plates which are opposed to one another and fixed together in corresponding positions, the plates being provided on their opposing surfaces with longitudinal rebates, beginning at a lower edge of the plates, the rebates defining a slot that can be coupled to the upper edge of the door, one of the plates being fitted on its external surface with at least one freely rotating wheel, the at least one wheel having an axis of rotation which is perpendicular to the plate, and the plate being fitted with a pivot designed to engage against the travel stops, the at least one wheel being supported by the longitudinal rib on the inverted groove in which the lower edge of the track ends.
