1. A poly axial hinge comprising:a mounting plate,
a first arm pivotally coupled to a panel mounting element at its first end,
a second arm pivotally coupled in a scissoring manner with the first arm by a main pivot, and pivotally coupled to said mounting plate at its first end,
a third arm pivotally coupled at a first end to said second arm at a location part way between said first end of said second arm and a said main pivot,
a first link member pivotally coupled at one end to a second end of said second arm, and pivotally coupled at another end to said panel mounting element,
a second link member pivotally coupled at one end to a second end of said first arm, and pivotally coupled at another end to another end of said third arm,
wherein said mounting plate includes at least one rigidly fixed first gear, and said third arm includes gear teeth directly or indirectly coupled together with said fixed gear, such that rotation of said second arm with respect to said mounting plate causes rotation of said first arm with respect to said second arm thereby driving the poly axle hinge open and/or closed.
