Claim 14:
15. An assembly comprising
a moving structure including a cover plate having a pair of apertures,
a fixed structure including a pair of screw bosses, the screw bosses having internal threads,
a pair of screws positionable through the pair of apertures of the cover plate, and
a pair of alignment sleeves, each alignment sleeve to receive one of the screws and engage one of the screw bosses, each alignment sleeve including:
a resiliently and flexibly collapsible body, the resiliently and flexibly collapsible body having a longitudinal length defining a longitudinal axis and a plurality of contraction members,
a first end that includes a guide configured to engage a screw of the pair of screws to align the screw along the longitudinal axis,
a second end that includes an alignment cup configured to engage a screw boss of the pair of screw bosses to align the alignment sleeve with the screw boss to guide the screw to engage the threads of the screw boss as the moving structure is aligned with the fixed structure,
wherein the alignment sleeve collapses longitudinally to reduce the longitudinal length of the collapsible body such that each contraction member is resiliently collapsed as the screw associated with the alignment sleeve is threaded into the screw boss and draws the moving structure toward the fixed structure.
