    Abstract: An apparatus for mounting a bifold door panel, and allowing the panel to run on a track. The apparatus has a trolley that runs within the track and a vertical elongate member that is axially movable relative to the trolley. A hinge or hinge portion is mounted on the elongate member, and a first support is disposed between the trolley and the hinge or hinge portion. The first support functions to support the hinge or hinge portion against a compression force arising from the bifold door panel when the apparatus is mounted on a top region of the panel. A second support is disposed at or toward the terminus of the elongate member and distal to the trolley. The second support functions to support the hinge or hinge portion against a compression force arising from the bifold door panel mounted thereon when mounted on a bottom region of the panel.

    Abstract: Door and window panels for use in building construction, and particularly bi-folding door and window panels. A latch mechanism and associated bolt are provided with a track to guide the bolt and a hinge fixing portion being disposed within the track. The hinge fixing portion provides a point of attachment for the hinge, and is movable within the track so as to be locatable at any level along the door or window panel as desired. The hinge fixing portion and/or track may be configured such that the hinge fixing portion is maintained clear of the bolt to allow the bolt to slide thereunder. In that context, the hinge fixing portion may perform two tasks: firstly the task of providing an anchor for the hinge, and secondly for maintaining itself clear of a bolt within the track.
