Patent ID: 8534633

Claim:
A suction cup for a vacuum powered tool, the suction cup comprising: a first or upper end configured to be brought into fluid flow communication with a vacuum source; a second or lower end opposite the first end and configured to be brought tightly into contact with a surface of an object to be handled by the vacuum powered tool; a sealing ring comprising a means for coupling formed integrally therewith and running circumferentially about an inner periphery of the sealing ring; at least one bellows comprising a first means for coupling formed integrally therewith and running circumferentially about an inner periphery in an upper end of the bellows, and a second means for coupling formed integrally therewith and running circumferentially about an outer periphery in a lower end of the bellows; and an end piece comprising a means for coupling formed integrally therewith and running circumferentially about an outer periphery of the end piece, wherein the means for coupling of the sealing ring is configured to selectively provide a form fitting engagement with another correspondingly-shaped one of the means for coupling of the end piece and the at least one bellows, the means for coupling of the end piece is configured to selectively provide a form fitting engagement with another correspondingly-shaped one of the means for coupling of the at least one bellows and the sealing ring, each of the first and second means for coupling of one of the at least one bellows is configured to selectively provide a form fitting engagement with another correspondingly-shaped one of the means for coupling of the end piece, the sealing ring, and another of the at least one bellows, the sealing ring, the at least one bellows, and the end piece form a set of connectable elements that are mutually connectable with one another, and each one of the means for coupling has a complementary shape with respect to other ones of the means for coupling and forms an interface that is common for all connections between the mutually-connectable elements in the set.
