Concealed multi pintle latch hinge

摘要

A spring hinge assembly is used as a concealed furniture hinge. A frame hinge section and a leaf hinge section are connected by link members each having two pivot points and being movable between an open and a closed position. The hinge sections are under spring action with respect to one another with the leaf hinge section being held by a spring latch in the closed position. The extension of one of the link members includes a control cam which coacts with a lever element. The lever element carries a roller and is under spring action. A biasing mechanism is located on that side of the lever element remote from the link supporting plate of the frame hinge section. The biasing mechanism is effective to simultaneously engage the lever element and the link supporting plate and the biased lever element and the supporting plate outwardly from the frame member.
