ABSTRACT:
A gate assembly is provided for positioning in an opening through which selective entry is required. The gate assembly includes barrier means mountable directly or indirectly to one or more surrounding surfaces defining the opening. Hinge means are provided to allow the barrier means to be movable relative to the surrounding surfaces in use between a closed position, wherein the opening is closed, to an open position, wherein the opening is open. The hinge means include a hinge pin movably mounted in a channel or recess. The channel or recess receiving the hinge pin in use has a taper which narrows from an opening of said channel or recess through which said hinge pin is located in use towards a base or opposite end of said recess or channel.
