Abstract
A mechanism that is comprised of two or more four-bar linkages is shown. Each linkage shares a common link with each adjacent linkage and the movement of said two or more linkages is synchronized by mechanical means such that said mechanism may move between a collapsed and an extended state. Said mechanical means may be in the form of additional links or geared connections.
