Abstract

A stabilized equipment support which is both small and light-weight in construction, for receiving equipment (e.g., a camera) with which it is to be used upon an expanded support network which complements the supported equipment in a manner which not only alters the position of the center of gravity for effective support of the resulting assembly, but which further ensures that the equipment support can be folded into a compact arrangement which does not significantly increase the profile, or overall size of the assembled combination, yet which is easily deployed to assume an expanded balanced arrangement which is appropriate for stabilized operations of the resulting assembly in simple and straightforward fashion, while minimizing the potential for precession during such use.
