Self closing multi pintle hinge

摘要

A wide-angle hinge assembly includes a frame hinge section and a door leaf hinge section connected to one another by a linkage arrangement. The linkage arrangement includes two double-armed link members and an intermediate link. The double-armed link members are pivotable about a common pivot point, and one of the link members pivotally engages one end of the intermediate link having its other end pivotally connected to the leaf hinge section. The linkage arrangement further includes a spring mechanism that is effective to provide a closing pressure during closing and maintaining the closed position for securing the door leaf. The spring mechanism is arranged on the intermediate link and coacts with a cam component included as a part of the leaf hinge section.
