Claim 4:
5. The condition activated door hinge retainer pin replacement device of claim 4, wherein the ratchet mechanism comprises:
a ring gear assembly with a series of teeth arranged circumferentially and extending inwardly;
a ratcheting slider disposed within the ring gear assembly, the ratcheting slider comprising a biasing spring and at least one slider tooth extending outwardly and engaging with the teeth of the ring gear assembly; and
an actuator shaft rotate-ably connected to the ratcheting slider, the actuator shaft comprising at least one cut-out section located adjacent to the ratcheting slider;
wherein the biasing spring of the ratcheting slider pushes the at least one slider tooth toward the teeth of the ring gear assembly, thereby engaging the ratcheting slider with the ring gear assembly;
wherein the teeth of the ring gear assembly are provided with a straight edge and an angled edge, the angled edge permitting the ratcheting slider to rotate relative to the ring gear assembly upon employment of a rotating force in a ratcheting direction, and the straight edge preventing the ratcheting slider from rotating relative to the ring gear assembly in an unwinding direction opposite the ratcheting direction; and
wherein, upon activation of the device due to the at least one sensor's detection of one or more triggering environmental conditions, rotation of the actuator shaft relative to the ratcheting slider withdraws the at least one tooth of the ratcheting slider from engagement with the teeth of the ring gear assembly, permitting rotation of the ratcheting slider relative to the ring gear assembly in the unwinding direction.
