Abstract

The hinge, shown in Figs. 1 and 2, is of a design that allows the pivot point of a door or cover to move in relation to the frame or unit to which the hinge is attached. The closed position of the hinge is shown in Fig. 1 and the open position in Fig. 2.

Moving Pivot Point Hinge

The hinge, shown in Figs. 1 and 2, is of a design that allows the pivot point of a door or cover to move in relation to the frame or unit to which the hinge is attached. The closed position of the hinge is shown in Fig. 1 and the open position in Fig. 2.

The pivot point is a part of a linkage system that is composed of a hinge plate 3 and a pivot plate 4. When the door 1 is opened, the hinged end comes in contact with the frame 2. This imparts a lever action which moves the plate 3 in an arc from a point of pivot on the hinge clip 6. The pivot plate 4 moves in a generally parallel direction with relation to door 1 and frame 2. The parallel action is controlled by control pin 5 and a slot 8 in hinge plate 3.

The door 1 is attached to the linkage system at pivot point 7, which in this system moves in a parallel direction a distance equal to twice the thickness of the door 1.

Once the linkage has moved to the extent of its travel, the door 1 is clear of other doors, not shown, and the frame 2. The door is therefore free to swing open to at least an angle of 135 degrees. This allows unobstructed access to the area normally covered by the door 1. When closing the door 1, it is swung shut first, then pushed to the closed position. Two hinges are required for each application.
