Abstract

A head-measuring device is disclosed and includes a support frame. The head-measuring device also includes a plurality of movable arms comprising a first set of movable arms and a second set of movable arms. The first set includes a first outermost arm, the second set includes a second outermost arm opposite the first outermost arm, and each movable arm is movable between a first position and a second position. The head-measuring device also includes a stationary arm coupled to the support frame such that the stationary arm is approximately equidistant between the outermost arms as the outermost arms are moved between the first and second positions. The plurality of movable arms are parallel to each other and to the stationary arm. The first and second sets of movable arms are mechanically linked such that the first set moves synchronously with the second set between the first and second positions.
