A hinge assembly including a first hinge leaf hingedly connected to a second hinge leaf by a hinge pin (14), the hinge pin (14) being rotatably mounted in one hinge leaf (12) non-rotatably mounted in the other hinge leaf (11), and a check mechanism (30) operably connected to the hinge pin (14) and said one hinge leaf (12) to releasably hold the first and second hinge leaves (11, 12) at at least one angular position about the hinge axis, the check mechanism (30) including check means (32) resiliently biased in a radial direction relative to the hinge axis and into contact with an annular cam track (34) formed on a reaction member (33), the check means (32) being driven along said annular cam (34) by relative rotation between said first an second hinge leafs (11, 12), the cam track (34) including at desired locations therealong one or more check formations (38) which cooperate with said check means (32) to releasably retain the first and second hinge leafs (11, 12) at a desired angular position relative to one another. |
