1. A frameless glass fencing hinge for a frameless glass fencing installation, the frameless glass fencing hinge including:
a first leaf assembly for operative attachment to a first glass panel or building structure; and
a second leaf assembly for operative attachment to a second glass panel, the second leaf assembly operatively adapted to undergo pivotal movement about a hinge axis so as to move the second glass panel between a closed position and an open position with the open position providing access to an area enclosed by the frameless glass fencing installation and the ability to exit from the frameless glass fencing installation;
wherein the first leaf assembly and the second leaf assembly define a cam formation operatively adapted to cause the second leaf assembly to undergo axial movement along the hinge axis between a rest position and a raised position when the second leaf assembly undergoes pivotal movement about the hinge axis;
wherein (i) the first leaf assembly includes a first knuckle body having a first cam surface, and (ii) the second leaf assembly includes a second knuckle body having a second cam surface operatively adapted for contact with the first cam surface, the first and second cam surfaces being configured such that movement of the second cam surface along the first cam surface causes the second leaf assembly to move axially along the hinge axis;
wherein the first and second cam surfaces are operatively adapted such that movement of the second cam surface along the first cam surface causes the second leaf assembly to be displaced vertically when the second leaf assembly undergoes axial movement along the hinge axis;
wherein the first and second cam surfaces are adapted to permit the second leaf assembly to move from the raised position to the rest position under the influence of gravity;
wherein the frameless glass fencing hinge includes a damping assembly to arrest movement of the second leaf assembly between the raised position and the rest position; and
wherein the damping assembly includes (i) a piston secured to the first knuckle body, and (ii) a damping chamber defined by an internal surface of the second knuckle body and a face of the piston, wherein movement of the second leaf assembly relative to the first leaf assembly causes the volume of air within the damping chamber to be increased and decreased respectively when the glass panel is moved between the closed position and the open position.
