Abstract
Abstract In a transport star for containers with a rotatable basic body and several gripper tongs mounted on its circumference, which are formed by clamps in the form of double-levers, a rotatable, lifter is provided mounted between the counterarms of radially inward-facing associated clamps, and the lifter forces the two adjacent counterarms apart in at least one angular or closed position and allows the counterarms to come together in at least one other angular or open position. In this way, low production costs, high operating safety, and universal application possibilities are achieved.

Transport star according to claim 2, wherein said basic body (13) has two parallel disks and/or rings (14, 15) between which said pins (10, 11, 12) are fastened, so that said pins can be loosened, with said clamps (5, 6; 7, 8; 46, 47), which are mounted on said pins.
Claim 5
Dependent Claim
48 words
Transport star according to claim 2 or 3, wherein said lifter (17, 44, 45) is formed essentially by two parallel flattened areas of a control shaft (18) which is mounted, so that it can be rotated, parallel to said pins (10, 11, 12) in said basic body (13).
Claim 6
Dependent Claim
81 words
Transport star according to claim 1, 2, or 3, wherein at least one control lever (19, 20) is fastened to a control shaft (18) of said lifter (17, 44, 45), wherein said control lever, together with stops (22, 23) mounted stationary relative to a rotational track of said transport star (1, 2, 38, 39, 40, 55), cause a controlled displacement of said lifter (17, 44, 45), and thus, an opening or closing of said clamps (5, 6; 7, 7; 46, 47).
Claim 7
Dependent Claim
60 words
Transport star according to claim 2 or 3, wherein said basic body (13) forms a circular structural unit with said pins (10, 11, 12) and said claims (5, 6; 7, 8; 46, 47) fixed on them, and said structural unit is fastened, so that it can be loosened, to a hub (2) equipped with one or more radial arms (24).
