ABSTRACT:
A new and novel concealed door hinge is disclosed and includes three pivot points, all of which are hidden when the door is closed. The device includes a substantially right angle interior leaf secured to the cabinet and a cup-like external leaf secured within a recess in the door. A forcing member is pivotally connected to one of the surfaces of the interior leaf and a pivoting member is pivotally connected to another surface of the internal leaf and to the external leaf. In one embodiment of the invention, when closing the door, a cam-like structure within the external leaf moves the forcing member to urge the pivoting member toward the door opening and, consequently, causes the entire hinge assembly to close. In another embodiment of the invention, the pivot point between the forcing member and the interior leaf is slidingly positioned with respect to the interior leaf. This embodiment also includes an axle which interconnects the forcing member and the pivoting member. This hinge assembly is particularly useful in cabinets positioned closely together or in recessed door cabinets where there is a small amount of room for the door to open and where it is desirable to open the door beyond 90.degree. as on cabinets, vehicles, safes and the like.
