Claim 9:
10. A door closing apparatus comprising:
a base plate configured to be coupled to a door, the door configured to be positioned in an open position and a closed position; and
a closing mechanism comprising a pivot cam, a closing bar and a cable;
the pivot cam is configured to be coupled to a hinge of the door using a hinge pin and coupled to the base plate using a tension member;
the closing bar is linearly movable and biasingly connected to the base plate and adapted to be releasably held in place via a pawl of a lever member;
the cable is connected at a distal end to the pivot cam and is connected at a proximal end to the closing bar, wherein when the door is pivoted into the open position the cable partially wraps around the pivot cam to move the closing bar;
the closing mechanism coupled to the base plate and having an unprimed state and a primed state, the closing mechanism configured to be transitioned between the unprimed state and the primed state by a user; wherein
in the unprimed state the closing mechanism is decoupled from operation of the door; and
in the primed state the closing mechanism is configured to move the door into the closed position responsive to receipt of a signal, and the closing mechanism is configured to allow movement of the door between the open position and the closed position in absence of the signal;
the closing bar including a plurality of gear teeth each adapted to releasably retain the pawl between any two of the plurality of the gear teeth.
