5. The damping hinge according to claim 1 , wherein the actuating member and the movable pressure member are configured for rolling engagement with one another, the rolling engagement causing movement of the movable pressure member vertically upon relative rotation of the second clamp plate towards the first clamp plate about the hinge axis to transmit force to the damper which, in turn, retards or controls closing of the hinge.
6. The damping hinge according to claim 5 , wherein the movable pressure member has a follower roller configured for rolling engagement with the actuating member, an outer surface of the follower roller being configured for rolling engagement with a surface of the actuating member in the manner of a cam follower, and wherein the surface of the actuating member is an inclined surface.
7. The damping hinge according to claim 6 , wherein the movable pressure member has at least one guide roller in rolling engagement with a wall or a surface of the clamp plate, on which the linear damper is arranged, for rolling movement in a vertical direction to transmit the force to the linear damper.
8. The damping hinge according to claim 7 , wherein the at least one guide roller is in rolling engagement with the follower roller, the at least one guide roller having a larger diameter portion in rolling engagement with the follower roller and a smaller diameter portion in rolling engagement with the wall or surface of the clamp plate, on which the linear damper is arranged, for rolling movement in the vertical direction.
9. The damping hinge according to claim 1 , wherein a damping mechanism is arranged on each of the first clamp plate and the second clamp plate, and wherein each damping mechanism includes a linear damper arranged substantially parallel to the hinge axis and configured to retard or control relative rotation of the second clamp plate towards the first clamp plate during closing of the hinge.
10. A damping hinge for controlled closing of a glass door or gate, comprising:
a first clamp plate configured to be mounted to a supporting structure;
a second clamp plate configured to be mounted to a panel of the door or gate, wherein the second clamp plate is connected with the first clamp plate for relative rotation thereto about a vertical hinge axis;
a damping mechanism arranged on either or each of the first clamp plate and the second clamp plate and having a linear damper that extends substantially parallel to the hinge axis, wherein one end of the damper is operatively fixed and an opposite end of the damper is operatively connected to a movable pressure member that is movable vertically to transmit force to the damper; and
an actuating member that extends towards the clamp plate on which the damping mechanism is arranged from the other clamp plate to operatively engage with the movable pressure member;
wherein the actuating member and the movable pressure member are configured for rolling engagement, the rolling engagement between the actuating member and the movable pressure member causing movement of the movable pressure member vertically upon relative rotation of the second clamp plate towards the first clamp plate about the hinge axis to transmit force to the damper which, in turn, retards or controls closing of the hinge.
11. The damping hinge according to claim 10 , wherein the movable pressure member has a roller for rolling engagement with the actuating member, and wherein an outer surface of the roller is configured for rolling engagement with a surface of the actuating member in the manner of a cam follower.
12. The damping hinge according to claim 11 , wherein the surface of the actuating member is an inclined surface.
13. The damping hinge according to claim 10 , wherein the damping mechanism is arranged such that the linear damper is positioned outside of a plane of the panel adjacent or next to an outer or facing surface of the panel.
14. The damping hinge according to claim 10 , wherein a damping mechanism is arranged on each of the first clamp plate and second clamp plate, wherein each damping mechanism includes a linear damper which is arranged vertically.
15. A damping hinge for controlled closing of a door or gate, comprising:
a first clamp plate configured to be mounted to a fixed supporting panel;
a second clamp plate configured to be mounted to a panel of the door or gate, wherein the second clamp plate is connected with the first clamp plate for relative rotation thereto about a hinge axis; and
