ABSTRACT:
Releasable suction cup assemblies for use in supporting an object on a smooth surface are formed by a cup body which has a duct passing therethrough and a valve element for selectively opening the duct whereby the vacuum of the suction cup can be released for repositioning the suction cup. The valve extends through the duct and is threaded on one end to receive a threaded fastener which is used to move the valve element into a sealing position and to secure the suction cup to an object. The stem portion of the suction cup may have an annular slot therein and an expanded lip which is deformed outwardly by inserting a plug in the slot.
