Patent attributes
Universal Coaster and Stacking Device comprising two similarly shaped flat members spaced from each other in parallel planes and defining a central axis normal to the parallel planes forming a space between the flat members, which have similar configurations and peripheral edges and surfaces facing in axially opposing directions. Three parallel fingers are parallel to the central axis and positioned radially beyond the peripheral edges and axially beyond the outwardly facing surfaces. A linkage assembly is arranged within the space that has link portions extending beyond the flat member peripheries for supporting the fingers and for selectively moving the fingers between fully retracted positions for storage and supporting smaller vessels and fully extended positions for supporting larger vessels on the link portions when said fingers are brought into proximity with vessels in contact with the device.
