Claim:
1. A lock pin mechanism for securing a closure to a structure, the lock pin mechanism comprising: a carriage on the closure and within the structure; at least one pin cylinder affixed to the carriage, each pin cylinder comprising a proximal end, a distal end, and a curvature of rotation therebetween, the pin cylinder being linearly moveable along a longitudinal axis of the pin cylinder; a rotation facilitator on the closure that engages with the curvature of rotation, and a rotating connector apparatus at the proximal end that rotatably attaches the proximal end of the pin cylinder to the carriage; such that each pin cylinder is independently rotatably attached to the carriage and is moveable, by the carriage, along the longitudinal axis of each respective pin cylinder, causing each rotation facilitator engaged with the curvature of rotation of each respective pin cylinder to rotate each pin cylinder on the carriage and around the longitudinal axis of the respective pin cylinder, so as to engage each pin cylinder with the structure.
