ABSTRACT

A vacuum holder for holding articles by suction includes a vacuum chamber
divided into a plurality of interconnected sub-chambers each communicating via
a control a passageway with a plurality of suction openings extending through
an outer holding surface, and a valve member for each control passageway
integrally formed with a mounting section mounted to the housing, and an
elastic juncture section normally biassing the valve member to open its
respective control passageway to permit the application of suction to its
plurality of suction openings. Each valve member is displaceable by the
suction force applied from its respective vacuum sub-chamber, when its
plurality of suction openings are not covered by the article to be held by the
holder, to thereby close the control passageway to its respective suction
openings.
