ABSTRACT:
An over-center self-closing hinge for furniture. In the door-related part of the hinge, which is in the form of a cup to be set in a mortise, there is provided a resiliently biased, pivotingly mounted cam which, in cooperation with a contact surface on the jamb-related part of the hinge, forms the over-center mechanism. Within the hinge cup there is provided a swivel arm which can be swung upwardly to a position in which it holds the resiliently biased cam in its dead-center position. With the swivel arm there is associated a resilient element which seeks to swing it up into the raised position. The resilient element is preferably an elastically flexible arm reaching beneath the swivel arm and joined fixedly to the cam adjacent the pivot axis thereof.
