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.

An infinite position door hold open comprising, in combination, a pair of pivotally interconnected hinge members movable in door opening and closing directions relative to each other, a brake pad mounted on one hinge member for movement therewith, a brake member mounted on the other hinge member for movement therewith and movement relative thereto into and out of frictional engagement with the brake pad to selectively and alternately hold the hinge members against movement or permit movement in either direction, a brake member actuator mounted on said other member, and cooperating frictionally engageable means on the brake member and brake member actuator operable upon reversal of the direction of movement of the hinge members for moving the brake member relative to the one hinge member and into frictional engagement with the brake pad to thereby hold the hinge members against movement in either direction.
