Abstract
Mechanisms designed to facilitate movement of tray tables or other platforms are addressed. Internal flexible sleeves provide more constant pressure on linearly-moving shafts associated with the tables, reducing or cancelling possible lateral misalignments of the shafts. Outer cases maintain the flexible sleeves in position, and positive stopping features may be employed to prevent extension or retraction of the shafts beyond desired amounts.
