Abstract:
1. A mechanism for the operation of multiple panels door working in conjunction with a pair of guide rails and panels further comprising: a pair of hinge mechanism for each of a plurality of garage door panels; said pair of hinge mechanism consisting of a clamshell module and a cam; said clamshell module having a first part on one said plurality of garage door panels and a second part on another one of said plurality of garage door panels; each said cam being rotationally attached to a plate and the plate having a clamshell module fixedly attached to the plate; the plate being fixedly attached to one of a plurality of said garage door panels; said cam being rotationally attached to said plate at said cam proximal end and rotationally attached to a blade at said cam distal end; each said blade being connected to a caster and each said caster rolling within one of said pair of guide rails; a top cam rotationally attached to a top plate on said top cam proximal end and said top plate being fixedly attached to a top panel said top panel being the uppermost of said plurality of garage door panels and; said top cam being rotationally attached to a secondary cam on said top cam distal end; said top cam situated between a top caster and said top plate; a first caster rotationally attached to a secondary cam and a long cam; a top cam having a distal end rotationally attached to a top plate and a proximal end rotationally attached to a top blade; a top blade having a proximal end rotationally attached to a secondary cam and said proximal end of said top cam; said top blade having said top blade distal end rotationally attached to a caster; said long cam having said long cam proximal end rotationally attached to said first caster and said secondary cam; said long cam having said long cam distal end rotationally attached to an attachment bracket; one top caster on each rail of said pair of rails; said first caster traveling from an horizontal part of said rail onto a vertical part of said rail as said multiple panels door closes; distance between said first caster and said distal end of said top blade being reduced so that said secondary cam and said top cam change their relative positions from a “Y” configuration into a “T” configuration; said “T” configuration inducing said cams from being substantially parallel to said rail to being substantially perpendicular to said rail.
