Abstract:
1. A hinge assembly including a first hinge leaf hingedly connected to a second hinge leaf by a hinge pin, the hinge pin being rotatably mounted in one hinge leaf and non-rotatably mounted in the other hinge leaf, and a check mechanism operably connected to the hinge pin and said one hinge leaf to releasably hold the first and second hinge leaves at least one angular position about the hinge axis, the check mechanism including a check body which is fixed to the hinge pin and is rotatably located within an annular cam track, the check body including two or more check members which are equally spaced from one another circumferentially about the hinge axis, the check members being resiliently biased in a radial outward direction relative to the hinge axis to engage and run along said cam track, the check body being driven along said annular cam track by relative rotation between said first and second hinge leafs, the cam track including at desired locations therealong one or more check formations which co-operate with said check means to releasably retain the first and second hinge leafs at a desired angular position relative to one another, the cam track being formed on a reaction member which is non-rotatably located in a housing fixedly secured to said one hinge leaf, the reaction member being in the form of an annulus.
