Block stacking arrangement

1. A block stacking arrangement comprising:

a plurality of container receiving slots;

a loading space arranged below the container receiving slots in a direction of gravity;

a pass-through opening between respective container receiving slots and the loading space; and

a holding device, which is arranged in the pass-through opening, having a flap pivotable about a shaft between a holding position and a release position,

wherein the shaft is mounted in an edge of the pass-through opening,

wherein the shaft is mounted at at least one end in a bolt socket that is upwardly open in the direction of gravity; and

further comprising a shaft hold-down device, which is fastened to the edge of the pass-through opening, arranged at least partially above the bolt socket in the direction of gravity to act on the end of the shaft.

2. The block stacking arrangement according to claim 1 , wherein the edge of the pass-through opening in which the flap is mounted is in a corner of the pass-through opening between a longitudinal side and a transverse side of the pass-through opening, and the shaft hold-down device is connected both to the longitudinal side and to the transverse side.

3. The block stacking arrangement according to claim 2 , wherein the shaft hold-down device is connected to the edge of the pass-through opening by screws.

4. The block stacking arrangement according to claim 3 , wherein the shaft hold-down device has a screw boss facing the edge of the pass-through opening for each of the screws.

5. The block stacking arrangement according to claim 1 , wherein the flap is pretensioned into the holding position by a spring.

6. The block stacking arrangement according to claim 5 , wherein the spring is designed as a coil spring arranged on the end of the shaft.

7. The block stacking arrangement according to claim 1 , wherein the pass-through opening has a positioning profile and the shaft hold-down device has a matching counter-profile.

8. The block stacking arrangement according to claim 1 , wherein the shaft hold-down device is designed as a plastic element.

9. The block stacking arrangement according to claim 1 , wherein the shaft hold-down device has an insertion bevel at its lower end in the direction of gravity.

10. The block stacking arrangement according to claim 1 , wherein the pass-through opening is formed in a frame arranged between the container receiving slots and the loading space, wherein the shaft is mounted in the frame.

11. The block stacking arrangement according to claim 10 , wherein the shaft hold-down device has an extension in the direction of gravity with which it covers the frame in the direction of gravity.

12. The block stacking arrangement according to claim 11 , wherein the shaft hold-down device has a recess in which the flap is received in the release position.

13. The block stacking arrangement according to claim 10 , wherein the shaft hold-down device forms a sliding surface on its side facing the pass-through opening.

14. The block stacking arrangement according to claim 1 , wherein the frame has longitudinal members and cross-members, which are connected to one another by angle elements,

wherein the shaft hold-down device is fastened to one of the angle elements, and

wherein the shaft hold-down device projects beyond the angle element in the direction of at least one of the longitudinal member or the cross-member fastened to the angle element.
