A linkage assembly includes a first link connected at a first point to a translation mechanism attached to a support structure. The translation mechanism is arranged to allow the first point of the first link to translate along a substantially straight axis. A second link is pivotally connected at a first point to the support structure, and at a second point to the first link. A second point of the first link travels on or near an arc of substantially constant finite radius when the first link pivots with respect to the second link. |
