ABSTRACT

A vacuum cup construction designed to support large items includes a planar
outer plate, and a planar, generally coincidentally shaped inner plate which
is smaller than the outer plate. A generally flat coincidentally shaped
compressible unmolded, non-preformed sealing member, which is larger than the
inner plate, is retained between the outer and inner plates by a threaded stud
and a threaded nut connecting the outer and inner plates, the tightening of
which compresses the sealing member. Compression of the sealing member causes
the periphery to deform and form a sealing edge. A vacuum passage passes
through the outer plate, the sealing member, and the inner plate to permit a
vacuum to be drawn when the assembly is placed against the surface of an item
or object.
