COMPRESSIBLE SUCTION CUP HAVING ADDITIONAL VACUUM COMPARTMENT, AS WELL AS LIP, AND BELLOWS THEREFOR

摘要

A suction cup for engaging and lifting an object is disclosed, comprising a lip, a bellows, and an upper portion sealingly connected to the bellows for connecting an inner volume of the suction cup to a source of vacuum, which cup, in an operative state, is capable of being locked in an at least partly compressed state of the lip and/or bellows. Locking is accomplished by air entrapped in a sealed exterior volume formed between the lip and bellows and/or between one or more segments of the bellows in an operative state being evacuated through one or more through open holes provided in the lip and/or bellows when vacuum is connected to the suction cup. A corresponding lip and a corresponding bellows for use in the suction cup are also disclosed.
