The invention relates to system for the mounting of shelves on a substantially rectangular load carrier having four identical columns arranged in the corners thereof. The system comprises columns having a rectangular profile with four side faces, a substantially rectangular shelf of a length which is shorter than the distance between the columns of the load carrier, on which shelf a holder is mounted that can be inserted into complementary slots in the columns of the load carrier, said slots being configured with a support face with which the holder is capable of engaging in such a manner that the holder supports on the column. The columns as such are configured with slots that extend symmetrically about a longitudinally extending center axis of one of the side faces and through the side faces adjacent to that side face. The slots are each separately configured with three substantially identical cut-outs, the one of which is situated in the axis of symmetry and the two remaining ones are in the adjacent side faces. The cut-outs are function as support faces for the holders of the shelf, them being arranged on the shorter sides of the shelf and extending in the longitudinal direction of the shelf to the effect that they are capable of engaging with the slots in the four columns arranged on the load carrier.

1. A system for the mounting of shelves on a substantially rectangular load carrier having four identical columns arranged at corners thereof, said system comprising: the four columns each having a rectangular profile with four side faces, a substantially rectangular shelf of a length which is shorter than a distance between corresponding columns of the load carrier,at least one holder mounted on said shelf, the at least one holder comprising two parallel legs and a middle part extending between the legs thereby creating an opening between the least one holder and the shelf,wherein slots are formed in each column and each slot extends symmetrically about a longitudinally extending centre axis of a first side face of the side faces and through the side faces adjacent to the first side face resulting in each of said slots continuously extending through three adjacent sides and having three downwardly-extending cut-outs, at least one of said cut-outs which is situated on the first side face and in an axis of symmetry of the column and the two remaining cut-outs are formed in the corresponding adjacent side faces, respectively, such that said cut-outs are configured to support each holder of the shelf, and the columns each define a protruding portion between an adjacent pair of downwardly extending cut outs, wherein one of said corresponding openings defined by a corresponding holder is configured to receive a respective protruding portion therein,wherein the at least one holder comprises at least two holders each extending outwardly in a longitudinal direction from two opposing ends of the shelf on shorter sides of the shelf and are configured to engage with corresponding slots of respective columns when the parallel legs and middle part of the holder are passed through the slots and engage two or more of the three downwardly-extending cut-outs of each slot arranged on the load carrier for simultaneous mounting of the shelf thereon and removal of the shelf therefrom without rotation of the shelf. 2. A system according to claim 1, wherein each opening has a rectangular shape. 3. A system according to claim 1, wherein the columns each have at least four slots to the effect that four shelves can be mounted on the load carrier. 4. A system according to claim 1, wherein the slots each have a fourth cut-out extending in a direction opposite one of the three downwardly extending cut-outs. 5. A system according to claim 1, wherein the slots each have a fourth cut-out extending in a direction opposite one of the three downwardly extending cut-outs, and wherein the fourth cut-outs on each said column comprises at least two different configuration shapes that alternate along the longitudinal direction of the respective columns. 6. A system according to claim 2, wherein the columns each have at least four slots to the effect that four shelves can be mounted on the load carrier. 7. A system according to claim 2, wherein the slots each have a fourth cut-out extending in a direction opposite one of the three downwardly extending cut-outs. 8. A system according to claim 3, wherein the slots each have a fourth cut-out extending in a direction opposite one of the three downwardly extending cut-outs. 9. A system according to claim 2, wherein the slots each have a fourth cut-out extending in a direction opposite one of the three downwardly extending cut-outs, and wherein the fourth cut-outs on each said column comprises at least two different configuration shapes that alternate along the longitudinal direction of the respective columns. 10. A system according to claim 3, wherein the slots each have a fourth cut-out extending in a direction opposite one of the three downwardly extending cut-outs, and wherein the fourth cut-outs on each said column comprises at least two different configuration shapes that alternate along the longitudinal direction of the respective columns. 11. A system according to claim 4, wherein the slots each have a fourth cut-out extending in a direction opposite one of the three downwardly extending cut-outs, and wherein the fourth cut-outs on each said column comprises at least two different configuration shapes that alternate along the longitudinal direction of the respective columns.
