A sliding door/window track assembly particularly suited for use with thick glass. Fastenable directly to both the upper and lower edges of such glass, the assembly includes a frame member made of plastic. The frame member is suspended between a pair of guides formed within a track member. A plurality of keys, which ride in slots formed in the sides of the guides, are employed not only to suspend the frame member but also to lock it into the track member for security. Moreover, the track member also allows a large amount of foreign material to be deposited along the track before any interference with operation occurs. Further, the track assembly can be fabricated so that only plastic material rubs on plastic when the door/window is slid, thereby allowing for free movement with little friction.

A track assembly for slideably supporting a sheet of material for a door comprising: (a) an elongated track member, each transverse cross-section thereof being approximately symmetrical; the track member including a first side wall which is disposed horizontally and a pair of guides which extend vertically therefrom; the guides being substantially mirror images of each other and spaced apart; the first side wall and the guides comprising a first single, unitary piece formed of plastic; (b) each guide having an opposing elongated slot which is disposed horizontally; (c) a frame member, each transverse cross-section thereof being approximately symmetrical; the frame member including a second side wall which is disposed horizontally and above the guides of said track member and a three-sided plug which extends vertically therefrom the plug extending substantially the length of the frame member; the frame member having third and fourth side-walls which extend vertically from the second side wall in a direction away from the plug, the second, third and fourth side walls forming a trough into which an edge of the sheet of material can be inserted; the plug being movable between the guides; the second, third and fourth sidewalls comprising a second single, unitary piece formed of plastic; and (d) a plurality of keys, each key being generally rectangular in shape and pivotally connected to a single side of the plug; contiguous pairs of keys being spaced apart; the ends of each key riding in the opposing slots.
