Compressible adsorption cups having additional vacuum compartments, and lips and bellows for them

摘要

Problem to be solved: to provide an adsorption cup which can be locked at least in a partially compressed state and has improved flexibility.Solution: an adsorption cup comprising a lip, a bellows, and an upper portion sealed in bellows to connect the internal volume of the suction cup to a vacuum source, is disclosed for the cup cup In an operative state, it can be locked in at least partially compressed states of the lip and / or bellows.The lock is formed between the lip and bellows and / or between the sealed outer volume formed between one or more segments of the bellows when the vacuum is connected to the suction cup in an operating state Achieved by evacuating through one or more through holes provided in the lip and / or bellows.Diagram
