In summary, this document describes a collapsible superstructure 1 for a pallet 15, wherein the superstructure 1 comprises: four corner profiles 10, a first pair of opposite sides 11 of the superstructure 1, a second pair of opposite sides 12a, 12b of the superstructure 1, wherein at least one of the sides in said first pair of opposite sides 11 or said second pair of opposite sides 12a, 12b is provided with an openable portion 16 in an opening. Moreover, the openable portion 16 is designed such that displacement, in a horizontal direction H along said side provided with an opening, of a first abutment portion relative to a second abutment portion, substantially diagonally opposite the first abutment portion, is counteracted, and such that displacement, in the horizontal direction H along said side provided with an opening, of a third abutment portion relative to a fourth abutment portion, substantially diagonally opposite the third abutment portion, is counteracted, whereby a unidirectional angle setting of the two corner profiles 10, connected to the side provided with an opening, along said side provided with the opening, is counteracted.

1. A collapsible superstructure for a pallet, wherein the superstructure comprises: four corner profiles arranged to, in a raised position of the superstructure, be placed standing upright, in a vertical direction (V), at each corner of said pallet,a first pair of opposite sides of the superstructure, which are structurally separate from and removably fastened to the four corner profiles, which sides are each provided with at least one inner hinge joint, standing upright in the vertical direction, and which sides are each connected to two corner profiles,a second pair, separate from said first pair, of opposite sides of the superstructure, which are structurally separate from and removably fastened to the four corner profiles and which sides are each connected to two corner profiles,wherein the corner profiles and the sides are produced from sheet metal;wherein, at each one of the corner profiles, at least one of the sides connected to the respective corner profile is connected via upright standing hinge joints for permitting collapse of the superstructure,wherein at least one of the sides in said first pair of opposite sides or in said second pair of opposite sides is provided with an openable portion in an opening,wherein the openable portion is designed such that displacement, in a horizontal direction (H) along said side provided with an opening, of a first abutment portion (A) relative to a second abutment portion (B), substantially diagonally opposite the first abutment portion, is counteracted, and such that displacement, in the horizontal direction along said side provided with an opening, of a third abutment portion (C) relative to a fourth abutment portion (D), substantially diagonally opposite the third abutment portion, is counteracted,wherein the first abutment portion and the third abutment portion are arranged to abut directly or indirectly on one of the corner profiles connected to the side provided with an opening,wherein the second abutment portion and the fourth abutment portion are arranged to abut directly or indirectly on the other of the corner profiles connected to the side provided with an opening, whereby a unidirectional angle setting of the two corner profiles, connected to the side provided with an opening, along said side provided with the opening, is counteracted,wherein the openable portion is composed of one or more sheet metal plates which are folded to form stiffening folds that extend substantially in the horizontal direction along said side provided with an opening, andwherein the stiffening folds in the horizontal direction extend across the whole of the openable portion. 2. The collapsible superstructure for a pallet according to claim 1, wherein the openable portion has a first stiffening portion and a second stiffening portion which are each arranged to extend substantially in the horizontal direction along said side provided with an opening, and which are located at a distance from each other in the vertical direction,wherein the first stiffening portion comprises the first abutment portion and the fourth abutment portion, andwherein the second stiffening portion comprises the second abutment portion and the third abutment portion. 3. The collapsible superstructure for a pallet according to claim 2, wherein the first stiffening portion and the second stiffening portion are connected to each other such that displacement of the first stiffening portion relative to the second stiffening portion, in the horizontal direction along said side provided with an opening, is counteracted. 4. The collapsible superstructure for a pallet according to claim 2, wherein the openable portion is provided with a first side-edge portion, which connects the first abutment portion to the third abutment portion, and is provided with a second side-edge portion, which connects the second abutment portion to the fourth abutment portion. 5. The collapsible superstructure for a pallet according to claim 1, wherein the openable portion is provided with a central opening. 6. The collapsible superstructure for a pallet according to claim 1, wherein the corner profiles connected to the side provided with an opening each comprise an abutment surface which at least partially extends in the vertical direction and which at least partially extends in a transverse direction (T) which is perpendicular to the side provided with an opening, andwherein the respective abutment portions of the openable portion are arranged to abut on the respective abutment surface of the corner profiles and are arranged to transfer pressure forces (F). 7. The collapsible superstructure for a pallet according to claim 1, wherein a non-openable portion of the side provided with an opening comprises, on both sides of the openable portion, an abutment surface which at least partially extends in the vertical direction and which at least partially extends in a transverse direction (T) which is perpendicular to the side provided with an opening, andwherein the respective abutment portions of the openable portion are arranged to abut on the respective abutment surface of the non-openable portion and are arranged to transfer pressure forces (F). 8. The collapsible superstructure for a pallet according to claim 1, wherein each one of the sides in the first pair of opposite sides is connected to two corner profiles via upright standing outer hinge joints for permitting collapse of the superstructure. 9. The collapsible superstructure for a pallet according to claim 1, wherein at least one of the sides in at least said second pair of opposite sides is provided with said openable portion in an opening. 10.
