Claim 0:
1. A door swing control device adapted to
enable a door that is hingedly affixed to a structure to swing between a closed position
and a first open position and between the first open position and a second open position,
the device comprising:
a bracket adapted to be affixed to the door;
a pivoting element pivotably affixed to the bracket or adapted to be pivotably affixed to the door, the pivoting element engaged with the bracket to limit a range of movement of the pivoting element relative to the bracket, the pivoting element comprising a finger extending therefrom; and
a swinging catch mechanism adapted to be mounted directly or indirectly to the structure, the finger of the pivoting element being selectively engageable with the swinging catch mechanism to selectively limit a range of movement of the pivoting element relative to the swinging catch mechanism and hereby selectively limiting a range of movement of the bracket relative to the swinging catch mechanism;
wherein, when the finger is engaged with the swinging catch mechanism, the device is adapted to hold the door to swing in the first open position;
wherein, when the finger is disengaged from the swinging catch mechanism, the device is adapted to allow the door to swing between the first open position and the second open position;
a strut adapted to restrain movement of the door from the closed position to the first open position and/or from the first open position to the second open position, the strut being (a) adapted to be pivotably affixed at a first end to the structure and (b) pivotably affixed at a second end to the bracket or adapted to be pivotably affixed at the second end to the door;
wherein the pivoting element is adapted to pivot relative to the bracket between a first position and a second position as the door moves, respectively, between the closed position and the first open position; and
wherein the bracket comprises a pin protruding from the bracket that is slidably engaged with an arcuate channel defined in the pivoting element such that the slidable engagement limits the range of movement of the pivoting element relative to the bracket.
