Abstract

A transport bag for the hanging transportation of goods by a transport device extending in a transport direction, the transport bag having a rear wall oriented in a transverse direction to the transport direction and a front wall oriented in a transverse direction to the transport direction, which are moveably connected to one another at an upper bag end and a lower bag end in such a way that the front wall can move relative to the rear wall between a filling position in which same is at a first distance to the rear wall, and an empty position in which same is at a second distance to the rear wall, which second distance is smaller than the first distance, and which transport bag can be connected in a hanging manner to the transport device by a connection means attached at the top on the rear wall.

3. The transport bag according to claim 2 , wherein the axes of the first rolling elements ( 17 a , 17 b ) are oriented transversely to the transport direction ( 26 ).

4. The transport bag according to claim 1 wherein the rear wall ( 11 ) is dimensionally stable.

5. The transport bag according to claim 4 , wherein the transport bag ( 10 ; 10 . 1 - 10 . 5 ) is frameless.

6. The transport bag according to claim 5 , wherein the rear wall ( 11 ) and front wall ( 12 ) are sections of an integral hollow chamber plate having hollow chambers and that is folded twice at a suitable spacing transversely to the longitudinal direction of the hollow chambers to form the rear wall ( 11 ), the front wall ( 12 ) and a bottom therebetween, in such a manner that the hollow chambers in the rear wall ( 11 ) and front wall ( 12 ) run vertically when the transport bag is hanging.

7. The transport bag according to claim 1 , wherein the rear wall ( 11 ) has a frame, which is dimensionally stable.

8. The transport bag according to claim 1 , wherein for the movable connection between the front wall ( 12 ) and the rear wall ( 11 ), a dimensionally stable bracket ( 18 ) is provided at the upper bag end ( 14 ), said bracket being mounted pivotably both on the front wall ( 12 ) and on the rear wall ( 11 ).

9. The transport bag according to claim 1 , wherein a dimensionally stable frame ( 19 ) or bottom ( 19 a ) is mounted pivotably on both the front wall ( 12 ) and the rear wall ( 11 ) on the lower bag end ( 16 ) for the movable connection between the front wall ( 12 ) and the rear wall ( 11 ).

10. The transport bag according to claim 1 , wherein in the region of the upper bag end ( 14 ), the front wall ( 12 ) has laterally arranged second rolling elements ( 15 a , 15 b ) for guiding and/or influencing the transport bag ( 10 ; 10 . 1 - 10 . 5 ).

11. The transport bag according to claim 10 , wherein the axes of the second rolling elements ( 15 a , 15 b ) are oriented transversely to the transport direction ( 26 ).

12. The transport bag according to claim 1 , wherein at least one access opening ( 20 a , 20 b ) is provided in the front wall ( 12 ), through which access to a transport space ( 21 ) inside the transport bag ( 10 ; 10 . 1 - 10 . 5 ) is possible.

13. The transport bag according to claim 1 , wherein the transport bag ( 10 ; 10 . 1 - 10 . 5 ) is open at the sides.

14. The transport bag according to claim 1 , wherein the transport bag ( 10 ; 10 . 1 - 10 . 5 ) is at least partially closed at the sides.

15. A method for filling the transport bag according to claim 1 , comprising moving the transport bag ( 10 , 10 . 1 - 10 . 5 ) hanging on the transport device ( 23 , 23 ′) from a freely hanging vertical position by pivoting the rear wall ( 11 ) in order to reach the filling position in a horizontal position in which the rear wall ( 11 ) is above the front wall ( 12 ) that the resulting distance between the rear wall ( 11 ) and front wall ( 12 ) is large enough for transport goods ( 22 ) to be placed therein.

16. The method according to claim 15 , further comprising pivoting the transport bag ( 10 ; 10 . 1 - 10 . 5 ) by moving the first guide elements ( 17 a , 17 b ) of the rear wall ( 11 ) upwards relative to the transport device ( 23 , 23 ′) on a slotted guide ( 27 ).
