Stacking storage arrangement

1. A stacking storage arrangement for containers, comprising:

at least one transverse connector;

multiple uprights that are connected to one another by the at least one transverse connector;

connection elements configured to connect the at least one transverse connector to multiple uprights;

each connection element being arranged to bear against a contact surface of a respective upright of the multiple uprights,

wherein each contact surface comprises a slot to which at least one screw protruding through a respective connection element is screwably connected,

wherein the slot is embodied in a projection, wherein the projection comprises outer sides that extend outwardly away from the respective upright and the outer sides of the projection are sloped toward each other relative to an axis of the at least one screw;

wherein a respective connection element from the connection elements is configured to laterally grip around the projection to press the outer sides of the projection inward so that a lateral force is created that increases a holding capacity of the stacking storage arrangement.

2. The stacking storage arrangement according to claim 1 , wherein each slot is continuous over an entire length of a respective upright of the multiple uprights.

3. The stacking storage arrangement according to claim 1 , wherein the respective connection element comprises sloped inner sides, which are sloped to match the outer sides of the projection.

4. The stacking storage arrangement according to claim 1 , wherein the slot extends all the way into a cavity of a respective upright.

5. The stacking storage arrangement according to claim 1 , wherein the multiple uprights are embodied as extruded elements or roll formed profiles.

6. The stacking storage arrangement according to claim 1 , wherein the multiple uprights comprise three types of uprights:

a first type having a cross-like cross-section,

a second type having a T-shaped cross-section, and

a third type having an angled or V-shaped cross-section.

7. The stacking storage arrangement according to claim 6 , wherein the first type of uprights are arranged in rows, such that the uprights of one row are arranged to be staggered from uprights of an adjacent row.

8. The stacking storage arrangement according to claim 1 , wherein the at least one transverse connector comprise a slot into which a screw protruding through the connection element is screwed.

9. The stacking storage arrangement according to claim 8 , wherein the slot in the at least one transverse connector is embodied in a projection around which the connection element laterally grips.

10. The stacking storage arrangement according to claim 9 , wherein the projection on the at least one transverse connector comprises side flanks that are sloped towards an axis of the screw, and the respective connection element comprises second sloped inner sides configured to matched the slope of the side flanks.

11. The stacking storage arrangement according to claim 8 , wherein the respective connection element comprises a load bearing section to which the at least one transverse connector is attached, and wherein the load bearing section is arranged below the at least one transverse connector.

12. The stacking storage arrangement according to claim 8 , wherein the at least one transverse connector is embodied as an extruded element or roll formed profile.

13. The stacking storage arrangement according to claim 8 , wherein the slot in the at least one transverse connector extends all the way into a cavity in the at least one transverse connector.
