<p>A damper assembly for a toggle-type hinge, comprising a holder 23 receiving linear damping device 17 and to be mounted in use onto the cup flange of the hinge with the axis of the damping device parallel to the rotational axis of the hinge movement, and an actuator 24 to convert rotational movement of the hinge into linear movement of the damping device over at least part of hinge travel. In one aspect the actuator is rotatably mounted in the holder in line with the axis of the damping device, in a further aspect the actuator includes an engagement means to one side of the hinge arm. The holder or actuator may include a helical cam groove 29 and the other of the holder or actuator may include a helical cam follower rib (30, fig.4), the cam follower may comprise pin and the cam groove may have a variable pitch. The actuator preferably has protruding member 28 for engagement with a striking plate (32, fig.1) of the hinge arm. The damper assembly may include two dampers coaxially aligned, one to each side of the hinge arias with separate actuators; the second damper may have different damping characteristics to the first damping device and may come into action at a different stage during closing of the hinge.</p> |
