Zusammenfassung:	The mechanism is intended for lifting rectangular boxes or the like from a random supply by means of a suction cup (21) which is held on a movable (2) carrier (1,3) and connected (23) to a vacuum source. The suction cup is carried via at least two universal gimbals (3,6,9,18,21) or ball joints arranged one above the other and the suction line (23) extends centrally through these joints. The two gimbal rings (6,18) may be pivotably connected (12,16) via forks (10,14) extending from both ends of a tubular coupling member (9), the upper ring (6) being pivoted (7,8) to the carrier (3) and the lower ring (18) pivoted (20,21) to the suction cup. A coil spring may be interposed between the two gimbals.
