Abstract
A knuckle-joint over-center hinge, in combination with a first member for connection to a wall and a second member for connection to a door, and a first arm and a second arm, respectively, pivotaly linked to the first and second member, and an over-center mechanism forcing the hinge resiliently towards one of its end positions. The mechanism includes a closing spring having one end disposed and supported at the first arm which has a portion of U-shaped cross-section and a transverse wall. A pusher is displaceably mounted in the first arm, while the closing spring is disposed within the U-shaped portion and supports itself with its one end on the transverse wall, while the other end of the spring engages the pusher. The first member has a cam projection in the vicinity of the point where the first arm is pivotally linked to the first member, and the pusher supports itself on the cam projection.
