A hanger hinge is used to suspend panels of a folding door or window from an overhead track. The hanger hinge has a hanger bolt with an externally threaded lower end on which a nut is threaded by a tool. The nut is located within a sleeve which engages the bolt to prevent relative rotation between the sleeve and the bolt. At least one hinge leaf is pivotally mounted on the hanger bolt and supported on the sleeve. Each hinge leaf is adapted to be fixed to a respective panel, and the position of the panel(s) is dependent on the extent to which the nut is threaded onto the hanger bolt. A key clip is used to lock the nut rotationally relative to the sleeve, so that the nut cannot rotate relative to the hanger bolt. The key clip is automatically disengaged when the tool is inserted in the nut, to permit the nut to turn relative to the bolt. |
