US 2021/0355723 A1 · Latching System for Door or Window 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.
