Abstract
An access door of an imaging device is movable between a raised closed position, a lowered open position, and a raised open position. A linkage assembly includes a lower link connected to the access door using a first revolute joint and an upper link connected to the access door using a compound joint. The compound joint is transformable between a prismatic joint and a second revolute joint, with the compound joint forming the prismatic joint as the access door moves between the raised closed position and the lowered open position and forming the second revolute joint as the access door moves between the lowered open position and the raised open position. The compound joint as the prismatic joint allows translational motion of the access door relative to the upper link. The compound joint as the second revolute joint allows rotational motion of the access door relative to the upper link.
