ABSTRACT:
A portable worktable includes a work platform and an automatic stabilizing mechanism for stably supporting the platform on an uneven floor. First and second horizontally spaced, generally parallel panels are arranged so as to extend downwardly from the work platform. The stabilizing mechanism includes a pair of support feet fixed to a lower portion of one of the panels. The stabilizing mechanism also includes a beam member which is swingably mounted at a lower portion of the other panel for swinging relative to the platform about a generally horizontal axis. Another pair of support feet are mounted on the beam member at respective opposite ends thereof so that the swinging axis of the beam is disposed centrally of the support feet on the beam. The device also includes a locking mechanism for releasably holding the beam member in a chosen fixed position relative to the platform.
