ABSTRACT:
An infinite position door hold open includes a pair of pivotally interconnected hinge members which are respectively mounted on the door and body. The door mounted hinge member pivotally supports an arcuate link having oppositely facing braking and frictional surfaces, both generated about the pivotal axis of the hinge members. The braking surface is frictionally engageable with a brake pad adjustably mounted on the body mounted hinge member. The engagement of the braking surface with the brake pad is controlled by pivotal movement of a wedging cam relative to the door mounted hinge member between non-wedging limit positions through an intermediate wedging position. The cam has a friction member in constant engagement with the frictional surface of the brake member. Any reversal of the direction of movement of the door relative to the body causes the friction member of the cam to move the cam to the intermediate wedging position and wedge the braking surface of the brake member into frictional engagement with the brake pad.
