Concealed hinge assembly for a door

Abstract

The invention relates to a concealed pivot hinge assembly [10] suitable for hingedly mounting a door [12] to a frame, particularly, although not exclusively, for connecting doors of storage, shipping and cargo containers, such as those which may be used on ships, rail lines and trucks, to a container in order to protect against theft. The concealed pivot hinge assembly [10] is characterised therein that it comprises a continuous, elongate hinge extending between and pivotably secured at two opposing ends thereof to the frame such that the hinge assembly [10] also constitutes a door post about which the door [12] is swiveled. The hinge assembly [10] comprises an internal axle shaft [18] which is secured at two opposing ends thereof to the frame; and an external load-bearing shaft [20] which extends coaxially with the internal shaft [18] and is pivotally secured at two opposing ends thereof to the frame such that the external shaft [20] is pivotable relative to the internal shaft [18], the arrangement being such that the door [12] is secured to the external shaft [20] so that pivoting of the external shaft [20] swivels the door [12] between a closed and an open position. The invention extends to a door [12] and a container [44] including such a concealed hinge assembly [10]. The invention also includes a remotely operable locking mechanism [56] for use in connection with such doors [12].
