Abstract
The present invention includes three off-set hinges adapted to utilize the weight of the door to cause the door to self position and allow manual operation of the door. A center hinge includes a top leaf, a center pin, and a bottom leaf. The center pin includes an upper pin-portion adapted to slidably insert into an inverted slot on a top socket of the top leaf and an oppositely disposed lower pin-portion adapted to slidably insert into an upright cylindrical slot of the bottom leaf. A gear is disposed intermediate to the upper pin-portion and lower pin-portion. The gear is fixed or otherwise coupled to the pin whereby rotation of the gear results in corresponding rotation of the pin including both the top portion and the bottom portion. The lower pin-portion further includes a beveled lower (distal) end. This bevel matches a corresponding bevel in the bottom leaf.
