The sprung hinge for a door flap hinged on its upper edge e.g. an upper flap for a cupboard, has an angled lever (3) which grips the inside of the door flap. The lever is joined to other control levers hinged on the support frame and with a compressed spring (21) element attached to one lever. In the lower, closed position of the door the lever linkage is at a dead point with the spring vector holding the flap closed. By slightly opening the flap the spring vector moves to enable the spring to assist in the opening of the flap until, in the open position, the spring holds the flap open. |
