The transport bag is attached, via a suspension means (17), in a suspended manner to a carrying means (23) of the conveyor member. The transport bag has two frame brackets (15, 16) which are pivotally connected to the suspension means. The two frame brackets (15, 16) are substantially 2-fold rotationally symmetrical to one another, but not mirror symmetrical to one another. ## Claims ### Claim 1 A transport bag for a suspended conveyor system, a rail-guided conveyor system or a transport chain conveyor system, the transport bag comprising: a conveyor member; a transport bag having a receiving region for receiving one or a plurality of units of goods; wherein the transport bag is attached, via a suspension means, rotatably about a vertical rotational axis in a suspended manner to a carrying means of the conveyor member; and two frame brackets which are pivotally connected to the suspension means wherein the two frame brackets are substantially 2-fold rotationally symmetrical to one another about the vertical rotational axis, but not mirror symmetrical to one another. ### Claim 2 (depends on 1) The transport bag according to claim 1, wherein the conveyor member comprises a carriage of the rail-guided conveyor system or a conveyor chain link of the transport chain conveyor system. ### Claim 3 (depends on 1) The transport bag according to claim 1, wherein the transport bag has at least one wall which defines the receiving region of the transport bag and which is pivotally connected at two edges of the wall to a respective region of one of the two frame brackets facing away from the suspension means. ### Claim 4 (depends on 3) The transport bag according to claim 3, wherein the at least one wall is realized as a carrying loop in the form of a panel made of a flexible material, for example a textile fabric or a foil. ### Claim 5 (depends on 3) The transport bag according to claim 3, wherein a first rigid wall and a second rigid wall are connected by a flexible base of the bag. ### Claim 6 (depends on 1) The transport bag according to claim 1, wherein a first frame bracket of the two frame brackets has a first engagement region adapted to be engaged by an actuator for pivoting the first frame bracket; and a second frame bracket of the two frame brackets has a second engagement region adapted to be engaged by an actuator for pivoting the second frame bracket; and the first engagement region of the first frame bracket is arranged about the rotational axis in 2-fold rotational symmetry with the second engagement region of the second frame bracket. ### Claim 7 (depends on 6) The transport bag according to claim 6, wherein the transport bag has at least one wall which defines the receiving region of the transport bag, and which is pivotally connected at two edges of the wall to a respective region of one of the two frame brackets facing away from the suspension means; the first engagement region, when looking perpendicular toward the at least one wall, protrudes on a first side over an outer edge of the at least one wall; and the second engagement region protrudes on a second side, opposite to the first side, over the outer edge of the at least one wall. ### Claim 8 (depends on 7) The transport bag according to claim 7, wherein the first engagement region protrudes laterally on the first side over the outer edge of the at least one wall; and the second engagement region protrudes laterally on the second side over the outer edge of the at least one wall. ### Claim 9 (depends on 6) The transport bag according to claim 6, wherein the transport bag has at least one wall which defines the receiving region of the transport bag, and which is pivotally connected at two edges of the wall to a respective region of one of the two frame brackets facing away from the suspension means; the first engagement region, when looking perpendicular toward the at least one wall, protrudes on a first side in a first region over an outer edge of the at least one wall; the first engagement region protrudes on a second side, opposite to the first side, in a second region over the outer edge of the at least one wall; the second engagement region protrudes on the first side in a second region over the outer edge of the at least one wall; and the second engagement region protrudes on the second side in a first region over the outer edge of the at least one wall. ### Claim 10 (depends on 6) The transport bag according to claim 6, wherein the first engagement region is realized as one or more sections of the first frame bracket; and the second engagement region is realized as one or more sections of the second frame bracket. ### Claim 11 (depends on 6) The transport bag according to claim 6, wherein the first engagement region and the second engagement region are realized as protruding rigid plates or pins attached to the frame brackets. ### Claim 12 (depends on 1) The transport bag according to claim 1, wherein the transport bag is connected to the conveyor member via a rotating joint in such a manner that it can rotate about the vertical rotational axis. ### Claim 13 (depends on 1) The transport bag according to claim 1, wherein the transport bag has a suspension hook; the conveyor member has a carrying hook; and the suspension hook is suspended in the carrying hook; wherein the suspension hook can assume at least two stable bearing positions in the carrying hook; and wherein the suspension hook in a first stable bearing position is rotated through a certain angle relative to the suspension hook in a second stable bearing position. ### Claim 14 (depends on 13) The transport bag according to claim 13, wherein the carrying hook of the conveyor member is configured in such a manner that in a certain spatial orientation of the carrying hook the suspension hook of the transport bag can assume a first stable bearing position in which the suspension hook is aligned in a first plane; and in the same spatial orientation of the carrying hook the suspension hook can assume a second stable bearing position in which the suspension hook is aligned in a second plane; wherein the first bearing position and the second bearing position correspond to local minima of the potential energy of the suspended transport bag; and wherein the suspension hook is transferable back and forth between the first stable bearing position and the second stable bearing position by rotating the suspension hook through a certain rotational angle.
