Fig. 10 is a cross section along the line X-X according to FIG. 9.

As can be seen from FIGS. 1 and 2, has a stator component 1 a generally rectangular, channel-shaped or U-shaped cross-section for a pallet support structure (see Fig. 2), narrow, curved flanges 2 are provided on the open rear side of this cross section. The overall depth of this Profile can, for example, substantially half or be slightly more than half the profile width, or the depth and width of the U-profile can be substantially chosen to be equal to each other. In the middle of the front side surface 3 of the stand component 1 is a vertical, channel-shaped recess 4 formed with rounded corners. On the bottom thief recess 4 is a vertically directed Row of at the same distance from each other, right-angled slots 5 in the form of elongated holes (see Fig. intended. Furthermore, there is a vertical web in each of the webs present on both sides of the channel-shaped recess 4 Row of slots 6 provided, each spaced apart by the same vertical spacing as the slots 5, however, are not in alignment with the latter in the transverse direction, rather opposite the slots are arranged offset. The slots 6 are preferably located in consideration of the height of the slots 5 in the Stand component 1 in each case essentially in the middle between these slots 5.

Each of the slots 6 (see FIG. 1) has an approximately rectangular upper part 7, which is formed by narrow roundings or shoulders 8, which, as can be seen, are advantageous

are liable to be slightly bevelled downwards, separated from a lower, longer part 9, with this part 9 tapers downwards to a short, lower edge 10. A narrow, semicircular one Cutout 11 projects beyond the upper part 7 of the slot 6.

A connection element which can be seen in FIGS. 3 to 6, which is used to produce a connection between the stator component 1 and a horizontally directed component, such as a beam (not shown) of the structure serves, consists of an elongated arm 12 of angled, substantially L-shaped cross-section (see Fig. 3) with a narrow, lateral flange 13 on the free, vertical edge of a front web 14 of the cross-sectional profile. This narrow flange 13 faces an opposite side flange 15 of the cross-sectional profile such an inner distance that the arm 12, when it is in the position shown in Fig. 7, the stator component 1 engages halfway, with between the side flange 15 of the arm 12 and the opposite Page 17 of the stand component there is a margin 16. The side flange 15 is flat and carries the (not horizontal member of any suitable channel-shaped, box-shaped or angular cross-section, which with the side flange 15 preferably by means of a welded connection or possibly also by means of Rivets attached.

The narrow side flange 13 is with one or more flat hooks 20 which are arranged protruding from its free edge. Generally there will be three such Hooks or teeth 20 (as shown) or also four hooks can be provided. If there is more than one hook, then these hooks 20 are at the same vertical spacing as the slots 5 in the channel-shaped recess arranged in the stand component · 1 from each other. Any of the hooks

030044/0809

has a generally rectangular shape with a short tongue or tab 21 (see Fig. 6) freely following protrudes below and opposite the edge of the flange 13 a Has distance 22 which is slightly greater than the material thickness of the stator component 1. The thickness 2 3 (see Fig. 7) of a hook or tooth 20 is chosen so that two hooks 20, 20 'on arms 12, 12' from each other oppositely aligned, horizontal components in each slot 5 in the channel-shaped recess 4 (see Fig. 7) can be taken close side by side. The corners of the hook 20 and its tab 21 are rounded or beveled (see Fig. 6). However, if desired, the tab 21 can also be tapered slightly inward be trained.

The front web 14 of the arm 12 has in its middle Area a hook-shaped or nose-shaped approach 25 or, as shown, a number of such hook-shaped approaches 25, each arranged with the same vertical spacing as the hook 20 and the slots 5 and 6 from one another are. The or each hook-shaped projection 25 consists of an inwardly pressed, bridge-shaped part an outline shape (see FIG. 5) which is essentially complementary to that of the slot 6 in the stator component 1, this bridge-shaped part made of the material of the arm 12 pressed and by means of rounded transitions 26, 27 (see Fig. 8) at its upper and lower ends with this arm 12 is still in one piece. If you first look at the upper end of the approach 25, it can be seen that a substantially rectangular or square upper part 28 (see FIG. 5) initially in its area 2 9 (see FIG. 8) downwards and against runs inclined over the inner surface of the web 14 at an angle of approximately 30 ° and then with its part runs essentially parallel to this surface downwards, but at a distance from said surface. This substantially parallel part 30 can be flat or planar (as shown) or it can be at its from the

Inner surface of the web 14 remote outer side be slightly rounded, but he is on its inner side is flat (as shown). A lower part 31, which is separated from the upper part 28 by narrow shoulders 32 (see Fig. 5) is separated, has a downwardly tapering shape, Which to the shape of the part 9 of the Slot 6 is complementary. This lower part 31 initially runs against the inner surface of the web 14 inclined downwards at an angle of approximately 30 ° and is then parallel to this inner surface after directed downwards. As can be seen from FIGS. 4, 5 and 8, is in the web 14 of the arm 12 above one of the hook-shaped lugs 25 an opening 33 is provided. Each hook-shaped projection 25 is dimensioned so that it is inserted into a slot 6 in a direction perpendicular to the front side of the stator component 1 and then after can be moved downward to cause the shoulders 32 of the lug 25 behind the corresponding fillets engage this slot, while the side edges of the tapered, lower part 31 are tight and fit flush with the side edges of the tapered portion of the slot 6. The interlocking ones Shoulders 8, 32 prevent movement of the arm 12 away from the stand component 1 and the mutual movement Fitting the respective side edges of the tapered parts 9, 31 ensures that very good Support surfaces available for transferring the load are, so that overall a firm and good connection between the arm 12 and the horizontal attached to it Component on the one hand and the stator component 1 on the other hand results.

The relative dimensions are chosen so that when the hook-shaped projection 25 is in a corresponding slot 6 is inserted, the hook 20 on the arm 12 is inserted at the same time into a corresponding slot 5, and that, when the arm 12 is lowered, so does the hook 20

Time since the hook-shaped projection 25 comes into engagement, engages over the lower edge of the slot 5. The hook 20 helps prevent separation with and when the hook 20 of a second arm 12 'also is arranged in a tightly engaging manner in the same slot 5 (see Fig. 7); then the two arms are 12, 12 " and their associated horizontal components are also fixed against transverse movement of the stand component 1 held.

Given the conditions of assembly, the interior surface of the front web 14 of each arm can be flat come against the outer surface of the web 3 of the stator component 1 to the plant, but the side flange 15 of the Arm 12 is separated from the opposite side 17 of the stator component 1 by the clearance 16. This Room for maneuver facilitates the installation of individual horizontal beams in the structure or their removal from it in those cases when other beams, especially beams under load, in their position and here remain with their ends in contact with the stator components. If necessary, the margin 16 can also used to hold other components, such as trim panels or any Fastening means, which are not shown in the drawings are.

The adjustment of the height of the connecting arms 12 and thus also of the horizontally oriented components attached to them is only dependent on the choice of the respective slots and 6 in the stand component 1, in which the Hook 20 and the lugs 25 are brought into engagement.

A modified embodiment of a stator component 1a is shown in FIGS. 9 and 10, which for larger Loads serves as that according to FIGS. 1 and 2.

The difference is that now two rows of narrower slots 5a in a wider channel-shaped Depressions 4a are provided, which serve to separately receive the hooks 20, 20 'of two arms 12, 12', i.e., instead of receiving them together side by side in wider slots of a single row, as shown in Fig. 7 is shown.

The stand components and link arms described above can be made of sheet metal, metal plates or metal strips in an economical manner and by means of known Easily create methods. Structural structures that such Components contained are not only stable, stable and robust, but also have a clean look Appearance and offer security, especially due to the lack of exposed protrusions or the like on the front and side surfaces of the stator component 1 and the connecting element 12. If necessary, can additional supporting and / or connecting and / or frame parts, which extend from the front to the rear of the supporting structure extend, get to installation. Furthermore, additional safety locking means can be provided to a prevent accidental upward displacement of the link arms.

The cutouts 11, of which each one overlaps an opening 33 in the arm 12 and thereby enables the introduction of locking bolts or pins of known locking means (not shown) in a simple manner. The semicircular shape of this cutout ensures a wide support surface for a bolt with a circular cross-section.

Holes 34 (see FIGS. 4 to 6) in the connecting arm 12 represent openings which, if necessary, are used for suspension

the arm attached to a beam can be used to hook this arrangement through a paint shop to be able to lead through.

One of these openings 34, for example the lower opening in the side flange 15, but can also be used as a so-called auxiliary opening serve to ensure accurate alignment during the operations of forming the arm. Furthermore is a series of openings 18 in the side flange 15 provided that in one of a number of mounting positions of the arm on a beam effective paint drying to ensure. However, if necessary, these openings 18 can also be used for other purposes to be used.

The side walls of the stand or post 1 can each be arranged with a vertical row of equally spaced, round openings (which are not shown), which can be used, for example, to to screw the elements used to stiffen the ends of the structural sections to the stand or post.
