Claim 0:
1. A condition activated door hinge retainer pin replacement device, comprising:
a lower extension pin sized and shaped to fit within a door hinge of a door
a first arm oriented to abut a door frame when the door is open and the device is installed in the door hinge;
a second arm oriented to abut the door when the door is open and the device is installed in the door hinge;
a spring having a coil and being configured to store energy that, when released, forces the first and second arms to rotate in opposing directions;
a condition sensitive module comprising at least one sensor capable of detecting one or more triggering environmental conditions, the condition sensitive module further comprising an activation system that electronically activates the device upon the at least one sensor's detection of a triggering environmental condition;
the activation system comprising a ratchet mechanism and a trigger mechanism, the ratchet mechanism operating to facilitate the winding and storage of energy in the spring by retaining the spring in a pre-activation position, and the trigger mechanism operating to release the spring by placing the device in a post-activation position upon detection of a triggering environmental condition by the at least one sensor of the condition sensitive module; and
a power source connected with the condition sensitive module;
wherein upon detection of a triggering environmental condition by the at least one sensor, the activation system operates to release the spring, and the energy stored in the spring operates to rotate the first and second arms in opposing directions, placing rotational force upon the door and door frame to close the door.
