Claim 6:
7. A method of controlling a swing of a door that is hingedly affixed to a structure between a closed position and a first open position and between the first open position and a second open position, the method comprising:
affixing a bracket of a door swing control device to the door;
pivotably affixing a pivoting element of the door swing control device to the bracket or 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
affixing a swinging catch mechanism of the door swing control device 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 thereby 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 door is able to swing between the closed position and the first open position;
wherein, when the finger is disengaged from the swinging catch mechanism, the door is able to swing between the first open position and the second open position;
pivotably affixing a first end of a strut to the structure and pivotably affixing a second end of the strut to the bracket or to the door;
wherein the strut restrains 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;
wherein the pivoting element pivots 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 a pin protruding from the bracket 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.
