The supports are downwardly open profiles having a first and a second side wall. A horizontal wall connects the side walls and forms a goods support. At least one crossbeam has two slots, each with a locking projection that engages in an opening in the respective side wall. The openings are located in short end portions of the side walls. Central portions form a majority length of the side walls. The end portions are separated from the central portions by a slot which extends from the lower edge of the side wall over a portion of the height of the side wall. The end portions have in the direction toward the lower edge thereof a wall extent which in comparison with the wall extent on the central portion is offset in the direction toward the profile center plane. ## Claims ### Claim 1 A rack for storing goods, comprising: two crossbeams (2, 3) which are arranged parallel with each other; and supports (5) which extend between the crossbeams (2, 3) and are supported on the crossbeams (2, 3), wherein the supports (5) are downwardly open profiles and are each composed of a first side wall (11) on one side of a vertical profile center plane (M), a second side wall (12) on another side of the vertical profile center plane (M), and a horizontal wall (10) which connects the first side wall (11) and the second side wall (12), wherein an upper side of the horizontal wall (10) forms a goods support (10A), wherein at least one of the crossbeams has a crossbeam upper side (6), a crossbeam rear wall (8), and two slots (21, 22) for securing one of the supports (5), wherein the two slots (21, 22) extend from the crossbeam upper side (6) into the crossbeam rear wall (8) and each have a locking projection (9), wherein the locking projection (9), in a locking state, engages in a positive-locking manner in an opening (4) in the respective side wall (11, 12), wherein the opening (4) is located in an end portion (15) of the respective side wall (11, 12), wherein the end portion (15) is short in comparison with a central portion (16) which forms a majority length of the respective side wall (11, 12), wherein the end portion (15) is separated from the central portion (16) by a slot (33) which extends from a lower edge (34) of the respective side wall (11, 12) only over a portion of a height of the side wall (11, 12) and wherein the end portion (15) has in a direction toward the lower edge (34) thereof a wall extent which in comparison with a wall extent of the central portion (16) is offset in a direction toward the profile center plane (M). ### Claim 2 (depends on 1) The rack as claimed in claim 1, wherein the wall extent of the end portion (15) is increasingly offset further in a downward direction in the direction toward the profile center plane (M). ### Claim 3 (depends on 1) The rack as claimed in claim 1, wherein the end portion (15) comprises a wall portion (14) which is arranged at a right-angle with respect to the horizontal wall (10) and which is in alignment with the central portion (16) and the offset wall extent. ### Claim 4 (depends on 3) The rack as claimed in claim 3, wherein the slot (33) extends as far as a height of the wall portion (14) which is in alignment with the central portion (16). ### Claim 5 (depends on 3) The rack as claimed in claim 3, wherein the opening (4) is mostly located in the wall extent which is offset in the direction toward the profile center plane (M) and extends upward into the wall portion (14) which is in alignment with the central portion (16). ### Claim 6 (depends on 1) The rack as claimed in claim 1, wherein the offset wall extent is composed of a sequence of wall portions (15a, 15b, 15c) which are arranged one above the other and which merge into each other along folding or bending lines. ### Claim 7 (depends on 6) The rack as claimed in claim 6, wherein the opening (4) extends at least over an entire height of an uppermost wall portion (15a) of the wall portions (15a, 15b, 15c) which are arranged one above the other. ### Claim 8 (depends on 1) The rack as claimed in claim 1, wherein on the end portion (15) the lower edge (34), starting from the slot (33), initially extends horizontally and then as an obliquely rising edge (37). ### Claim 9 (depends on 1) The rack as claimed in claim 1, wherein the horizontal wall (10) of the support (5) merges at the end thereof facing the crossbeam (2,3) into a declining chamfer (35). ### Claim 10 (depends on 9) The rack as claimed in claim 9, wherein the crossbeam upper side (6) is composed of a horizontal face and an oblique face (13) which is adjacent in the direction toward the crossbeam rear wall (8). ### Claim 11 (depends on 10) The rack as claimed in claim 10, wherein the chamfer (35) which is formed on the support (5) meets the oblique face (13) which is formed on the crossbeam upper side (6) at an angle between 20° and 60°. ### Claim 12 (depends on 1) The rack as claimed in claim 1, wherein the side walls (11, 12) in a longitudinal direction of the supports (5) are composed of the end portion (15), the central portion (16) which follows the slot (33), and an additional end portion (17) at another end of the support (5). ### Claim 13 (depends on 1) The rack as claimed in claim 1, wherein the side wall (11, 12) of the central portion (16) has a greater height than of the end portion (15). ### Claim 14 (depends on 12) The rack as claimed in claim 12, wherein the side wall (11, 12) of the central portion (16) has a greater height than of the end portion (15) and of the additional end portion (17). ### Claim 15 (depends on 1) The rack as claimed in claim 1, wherein the locking projections (9) of the two slots (21, 22) are orientated toward each other. ### Claim 16 (depends on 15) The rack as claimed in claim 15, wherein for supporting the support (5) on the crossbeam (2, 3) on each locking projection (9) there is formed a support face (9A) which is directed toward the crossbeam upper side (6) and on which the edge (4a) of the respective opening (4) is supported. ### Claim 17 (depends on 15) The rack as claimed in claim 15, wherein the crossbeam rear wall (8) in order to form the slots (21, 22) is provided with punched-out portions, which define contours of the two locking projections (9) and wherein mutually facing portions of the contours are chamfers, a largest spacing (A1) of which with respect to each other is greater than a spacing (A2) which the lower edges (34) of the end portions (15) have with respect to each other. ### Claim 18 (depends on 1) The rack as claimed in claim 1, wherein the crossbeam (2) has a crossbeam front side (50) which is integral with a wheel guide (51) in the form of a channel-like rail. ### Claim 19 (depends on 1) The rack as claimed in claim 1, wherein the support (5) has an edge (80) which protrudes over the horizontal goods support (10A) and which extends longitudinally with respect to the goods support (10A) over an entire length of the support (5).
