DESCRIPTION

Arrangement with at least two baskets stackable on top of each other

[0001]The invention relates to an arrangement according to the preamble of claim 1.

[0002]In the state of the art, arrangements with baskets stackable on top of each other in a plurality of configuration forms are known. It is also known to provide devices on the side walls of the baskets with which the baskets stacked on top of each other can be connected, as shown for example in document EP 3 434611 A2, or which serve to stabilize the boxes stacked on top of each other. another, as shown, for example, in document AT 321 809.

[0003] DE 91 05 963 U1 discloses a generic arrangement in which the coding body is removable. Document US 2007/0080089 A1 discloses stackable boxes that can be connected to each other at their corners by means of pins.

[0004]In some forms of application it is important that the baskets stacked on top of each other can only be stacked on top of each other in a single stacking position.

[0005]The objective of the invention is therefore to improve an arrangement mentioned at the beginning in such a way as to ensure that the baskets can only be stacked on top of each other in a single stacking position.

[0006]To achieve this objective, the invention provides that the coding body can only be inserted into the coding body housing in a single stacking position to an extent sufficient to stack the baskets on top of each other.

[0007]A two-basket stacking position is, in this regard, a position in which the baskets are stacked on top of each other along their side walls and their side walls are aligned with each other or are placed coincident with each other. seen from above. Therefore, a stacking position is not arranging the baskets in any way, that is, for example, crossed or transversely on top of each other.

[0008]The stacked arrangement of the baskets in a stacking position is therefore only possible according to the invention if the coding body can be inserted sufficiently into the coding body receptacle. This can be achieved through several measures. For example, it may be provided that the coding body is the only coding body of the lower basket and the coding body housing is the only coding body housing of the upper basket. However, it is also possible that the coding body housing is the only opening on the underside of the side walls of the upper basket into which the coding body can be sufficiently pushed or even fitted. This can be achieved either by the appropriate shape of the coding body and the coding body housing or simply by the size of their cross-sectional surfaces relative to each other. In such configurations, there can then be several openings on the underside of the side walls of the upper basket, wherein precisely only one of these openings can be used as a coding body receptacle for the coding body due to a corresponding size or cross-sectional area. transversal and/or shape.

[0009]The preferred embodiments of the invention provide that the coding body can be fixed to the upper side of the side wall of the basket in each lower case by means of a non-destructively separable fixing device. This means that the encoding body can be used when necessary to ensure stacking at the only possible stacking position. The encryption body can also be removed if this security is not necessary.

[0010]In order to be able to easily fix the coding body manually in the lower basket and also remove it again from it, preferred variants provide that the fixing device is configured for tool-free fixing of the coding body to or on the upper side of the side wall of the basket in each lower case and/or for tool-free separation of the upper side of the side wall of the basket in each lower case.

[0011]A particularly preferred variant provides that the coding body can be fixed or is fixed on or on the upper side of the side wall of the basket in each lower case by means of a snap-in connection.

[0012]Other characteristics and particularities of preferred configuration forms of the invention are explained below by means of embodiment examples. It should be noted in this regard that the individual characteristics of these embodiments are not necessarily linked to the other characteristics of the respective embodiment, but can also be combined in other combinations or individually with the basic idea of the invention.

[0014]To form arrangements according to the invention with at least two baskets 20, 21 stacked on top of each other in a unique stacking position, a wide variety of types of baskets can be designed according to the invention.

[0015]The coding body 26, the coding body housing 27 and their function will be described in detail later in the description with reference to Figures 17 to 30.

[0016]A special configuration of a basket arrangement and its structure will be previously explained with the help of Figures 1 to 16, this basket arrangement being able to be used in principle as a lower basket 20 or as an upper basket 21 in the invention.

[0017]Figure 1 shows in a perspective representation an exemplary embodiment of a basket arrangement with a base basket 1 and an attachment piece 2 and connection supports 3, wherein the base basket 1 has a basket bottom 4 and side walls 5 and in the side walls 5 and in the superimposed part 2, receiving recesses 6 or 7 are each formed for the connection supports 3, where the superimposed part 2 is fixed to the base basket 1 of distanced from the base basket 1 by means of the connection supports 3 releasably interlocked in the accommodation spaces 6 and 7. The connection supports 3 are releasably interlocked in one of the accommodation recesses 6 of the walls sides 5 of the base basket 1 in each case by means of a rotary lock 8 and are releasably locked in one of the receiving recesses 7 of the superimposed part 2 in each case by means of a rotary lock 8. Advantageously, In this regard, it is provided that the connecting brackets 3 are mounted or can be mounted by means of the respective rotary lock 8 in the respective receiving recess 6 or 7 rotatably back and forth in each case between a locked position and a position unlocked.

[0018]Such basket arrangements could also be called modularly constructed baskets or simply modular baskets. The basket arrangements are created by correspondingly assembling the base basket 1 and the overlay 2 by means of the connecting brackets 3, where the overlay 2 can be fixed to the base basket 1 at different heights or at different distances from it. using 3 connection brackets of different lengths. In this way, the basket arrangements can be easily adapted to the size or height of the objects to be stored in the basket arrangement. The baskets or basket arrangements can be used, for example, as dish baskets, for example for glasses or plates, but also as so-called industrial baskets for storing and storing various technical objects in them or simply as storage baskets and/or baskets Of transport. The term basket could also be replaced by the term box, that is, one could speak of box arrangements or boxes constructed in a modular manner or simply of modular boxes.

[0019]If these basket arrangements are not only used for storing and/or transporting, but also for washing or rinsing and/or also for drying the objects stored in them, it is advantageous if the basket bottom 4 of the base basket 1 is formed, as is known in itself, as a grid or at least has openings in some way. The side walls 5 of the base basket can also have openings or can also be configured as a grid.

[0020]The base basket 1, the attachment piece 2 and the connecting brackets 3, as well as the coding body 26, are advantageously made of plastic. These may, for example, be injection molded parts. Fortunately, the entire basket arrangement is made of plastic.

[0021]In the sense of the fastest possible connection of the base basket 1 with the attachment piece 2, preferred forms of configuration provide that the respective connection support 3 can be releasably locked by means of a single rotary movement by means of of the respective rotary lock 8 simultaneously both in one of the accommodation spaces 6 of the side walls 5 of the base basket 1 and in one of the accommodation spaces 7 of the overlay 2. In the case of connection supports 3 that are preferably elongated, the rotary movement advantageously takes place around a longitudinal axis of the respective connection support 3.

[0022]In Figure 2, the base basket 1, the overlay 2 and the connection brackets 3 are shown in an exploded view. In Figure 2, the connection brackets 3 are thus unlocked and are shown removed from the respective accommodation spaces 6 or 7 of the side walls 5 of the base basket 1 and the superimposed piece 2. In this state, the brackets Connecting brackets 3 can be replaced by other connecting brackets 3, in particular longer or shorter connecting brackets 3, to connect the superimposed part 2 to the base basket 1 at a different height or at a different distance from it.

[0023]In this, as well as in other preferred configuration forms, the overlay 2 is configured as an overlay frame. This surrounds a central opening in the form of a frame, but has no bottom itself. Unlike the exemplary embodiment shown in this case, such a basket arrangement could also present as a superimposed piece 2 a superimposed basket with a basket bottom and with side walls, the recesses for housing the superimposed basket being arranged on its side walls. The superimposed basket could, for example, also be constructed in the same way as the base basket 1. In such configuration forms, which are not shown here, the basket arrangement would have several baskets stacked on top of each other and fixed from each other in a distanced manner by means of the connection supports 3.

[0024]Of course, the number of connecting brackets 3 per basket arrangement may vary. It is not necessary, as implemented in this case, to provide in each case two connection supports 3 for each side wall 5 of the base basket 1. The positioning of the connection supports 3 on the side walls 5 of the base basket 1 and the superimposed piece 2 may also differ from the embodiment example shown here. For example, it would also be conceivable to place the connecting brackets 3 in the corner areas of the side walls 5 of the base basket 1 and the overlay 2, but also in the more central areas of the respective side wall 5.

[0025]Optionally, a label holder 16 can be provided, shown in Figures 2, 3 and 4. As in the example embodiment shown in this case, this can be placed on one of the side walls 5 of the base basket. 1, for example, by means of a clip 17.

[0026]Figure 5 shows a top view of the basket arrangement of Figure 1. Figure 6 shows the vertical section along the cutting line A-A of Figure 5 and Figure 7 shows a detail view of the area B of Figure 6. Figure 8 shows a section analogous to that of Figure 6, but with only the base basket 1 being represented. Figure 9 shows only the superimposed piece 2 in an analogous section. Figure 10 shows area C of Figure 8, enlarged. Figure 11 shows area D of Figure 9, enlarged. The connection supports 3 used in this case in this example of embodiment of the invention are shown in Figures 12 to 14, Figure 14 showing the section along the cutting line E-E. Figures 15 and 16 show the rotary lock 8 in a view towards the accommodation cavity 6 or 7, Figure 15 showing the unlocked position in which the connection support 3 can be removed from the accommodation cavity 6 or 7. Figure 16 shows the locked position in which the connection brackets 3 are locked in the respective housing recesses 6 or 7 by means of the rotary lock 8. As is also implemented in this case, the rotary locks 8 in the housing recesses 6 of the side walls 5 of the base basket 1 are advantageously configured identically to the rotary locks 8 in the accommodation recesses 7 of the superimposed piece 2. Thus, in this exemplary embodiment, figures 15 and 16 show both the rotary lock 8 in the accommodation gap 6 of the side walls 5 as in the accommodation gaps 7 of the superimposed piece 2.

[0027]Advantageously, as also implemented in this case, it is provided that the rotary locks 8 are formed in each case by a rotatable locking part 9 formed in the connection support 3 and a rotatable locking part 10 formed in the recess housing 6 or 7. Preferably, it is also provided that the rotary locking part 9 formed in the connection support 3 can be inserted into the rotary locking part 10 formed in the housing recess 6 or 7 and can be removed from it. in the or in an unlocked position and is locked in the or in a locked position. This is also implemented in the variant shown in this case.

[0028]If we now look at figures 6 and 7, it can be seen that the rotary lock 8 is arranged a little more recessed both in the accommodation spaces 6 of the side walls 5 and in the accommodation spaces 7 of the superimposed piece. 2. This has the advantage that the connection brackets 3 are supported in each case by the wall sections adjacent to the rotary lock 8 and surrounding the receiving recesses 6 or 7. Of course, this recessed arrangement of the rotary lock 8 also It may be configured differently, deviating from the variant specifically shown in this case.

[0029]As also implemented in this case, the rotary locks 8 in the two receiving recesses 6 and 7 are preferably configured identically. In this way it is possible that the respective connecting bracket 3 can be releasably locked by means of a single rotary movement by means of the respective rotary lock 8 simultaneously both in one of the receiving recesses 6 of the side walls 5 of the base basket 1 as in one of the accommodation spaces 7 of the superimposed piece 2.

[0030]The rotary locks 8 can be configured so that they have stops both in the locked position and in the unlocked position. In these configurations, the connecting supports 3 can then only rotate back and forth between the unlocked position and the locked position. However, preferred configuration forms, such as the one implemented in this case, provide that each of the rotary locks 8 has a succession of alternately consecutive locked positions and unlocked positions, where the respective connection support 3 can be successively brought to a from the locked positions and to one of the unlocked positions, additionally rotating in a single direction of rotation. Generally speaking, the rotary locks 8 could also be called interlocking devices or interlocking device. The connecting brackets 3 could also be called studs, connectors or intermediate pieces. Favorably they are configured elongated. Its rotary locking parts 9, which are provided to form the rotary lock 8 according to the invention, are favorably located at opposite ends of the connecting brackets 3. The connecting brackets 3 are favorably offered in different lengths.

[0031]The rotary locking devices 8 used in such basket arrangements can in principle be designed very differently. For example, it can also be a threaded or screwed connection, a type of bayonet closure or the like. However, the preferred forms of configuration provide that when the connecting supports 3 are rotated between the locked position and the unlocked position, there is no stroke in the longitudinal direction of the connecting supports 3, so that the superimposed piece 2 always remains at the same distance from the base basket 1 when locking or unlocking. This is possible, for example, if, as provided in the preferred embodiment variants, the rotary locking part 10 formed in the receiving recess 6 or 7 has at least one rim 11 and the rotary locking part 9 formed in The connection support 3 has at least one pair of clamping bodies 13 that delimit a rim receiving gap 12, 14, in which the rim 11 can be held in the locked position in the rim receiving gap 12 between the clamping bodies 13, 14, preferably elastically. In preferred configuration forms, such as the one shown in this case, it is even provided that the rotary locking piece 10 formed in the accommodation recess 6 or 7 has a succession of flanges 11 arranged in a plane and the rotary locking piece 9 formed in the connection support 3 there is at least one pair, preferably a number of pairs corresponding to the number of flanges 11, of clamping bodies 13, 14 that delimit a flange accommodation gap 12, wherein the flanges 11, preferably all, they can be held in the locked position in one of the flange receiving recesses 12 between the clamping bodies 13, 14. This also makes it possible to configure a succession of alternatively consecutive locked positions and unlocked positions, where the respective connection support 3 can be successively brought to one of the locked positions and to one of the unlocked positions, additionally rotating in a single direction of rotation. In this way, it does not matter in which direction the connection support 3 is rotated to take it from the locked position to the unlocked position or vice versa. The flanges 11 arranged in a plane in this variant can be seen in figures 6 to 11, as well as 15 and 16. Due to this arrangement of the flanges 11 in a plane, during locking and unlocking no stroke is generated in the longitudinal direction of the respective connection support 3.

[0032]In the variant shown in this case, the flanges 11 are arranged in a square. But this is just an example. Other polygons with a different number of edges 11 are also possible, for example, to implement the succession of edges 11 arranged in a plane.

[0033]With regard to the rotary locking parts 9 of the connection supports 3, reference is made to Figures 12 to 14 as an example. In the longitudinal section according to Figure 14, in particular, it is easy to see that each of the rotary locking parts 9 has a number of rim receiving recesses 12 corresponding to the number of rims 11 of the rotary connection part 10 , which are delimited in each case by a pair of two clamping bodies 13 and 14. By means of the clamping bodies 13 and 14, a flange 11 can in each case be held, preferably elastically, in the flange accommodation recess. 12. Between the clamping bodies 13, which are formed in each case in the end area of the respective connection support 3, there are in each case intermediate zones 19 without rim receiving recess 12. These intermediate zones 19 are arranged more near the rotation axis 32 than the clamping bodies 13. The rotation axis 32 is the axis around which the respective connection support 3 can be rotated from the unlocked position to the locked position and vice versa.

[0034]The clamping bodies 14 pointing in the direction of the center of the respective connection support 3, seen in the longitudinal direction of the connection support 3, are formed in a kind of common disc-shaped structure in this exemplary embodiment, which does not necessarily have to be the case. In this case, however, it is in any case favorable if this disc-shaped structure has at least one recess 18. The function of the recess 18 is explained in detail below.

[0035]Before the connecting brackets 3 can be rotated from the unlocked to the locked position, they must first be pushed into the respective housing recesses 6 or 7 until their rotary locking parts 9 can engage with the rotary locking parts 10 into the accommodation spaces 6 or 7 by means of a subsequent turn. This insertion as well as the extraction takes place in the position that can be seen in Figure 15. In this position, the intermediate zones 19 can be guided beyond the flanges 11 until the clamping bodies 13 have been pushed between the flanges 11 so much that a rotary movement around the axis of rotation 32 is then possible. If, starting from Figure 15, the connection support 3 is rotated around the axis of rotation 32, the clamping bodies 13 and 14 engage with the respective flange 11, the flange 11 then resting in the respective flange accommodation gap 12 between the clamping bodies 13 and 14. By means of a sufficiently large rotation, the locking position shown in Figure 16 is reached, in which the Flanges 11 are held in the flange accommodation spaces 12 between the clamping bodies 13 and 14, preferably by means of elastic fastening. This position can also be seen well in figures 6 and 7.

[0036]Unlike the variant shown in this case, it would of course also be possible to configure the rotary locking parts 9 and 10 in reverse. In this case, the rotary locking parts 9 of the connection support 3 would have corresponding flanges 11 and the rotary locking parts 10 of the accommodation gap 6 or 7 of the side walls 5 or of the superimposed part 2 would have corresponding housing gaps. flange 12 with corresponding clamping bodies 13 and 14.

[0037]It can also be provided that, as is also implemented in this case, water evacuation openings 15 are formed in the connection supports 3 in each case to evacuate the water that penetrates into the accommodation cavity 6 or 7 in the one in which the respective connection support 3 is locked. This serves to ensure that, for example, during washing or rinsing operations, the water that eventually enters the accommodation recesses 6 or 7 does not remain in the respective rotating interlocks 8. To this end, in the example of embodiment shown, they are water evacuation openings 15 are provided in the connection supports 3. The water that penetrates into the accommodation gap 6 or 7 can escape through it and through the recess 18 from above and, therefore, does not remain in the accommodation recesses 6 or 7 above the connection supports 3 or their rotary lock 8.

[0038]The coding body 26, essential for the invention, is already represented in figures 1 and 2, as well as in 6 and 7. Together with the accommodation of the coding body 27, it ensures that, in an arrangement with at least two baskets 20 and 21 stackable on top of each other, these baskets can only be stacked on top of each other in a single stacking position. In other words, the coding body 26 together with the coding body housing 27 prevents two baskets from being stacked on top of each other in different stacking positions. A two-basket stacking position is, in this regard, as already explained at the beginning, a position in which the baskets are stacked on top of each other along their side walls and their side walls are aligned with each other or are aligned. They are placed coinciding with each other seen from above. Therefore, a stacking position is not arranging the baskets in any way, that is, for example, crossed or transversely on top of each other.

[0039]As already mentioned at the beginning, the invention provides for an arrangement with at least two baskets 20, 21 stackable on top of each other, where each of the baskets 20, 21 has a basket bottom 4 and side walls 22, 23 and, when the baskets 20, 21 are stacked on top of each other, the lower sides 24 of the side walls 23 of the basket 21 in each upper case rest on the upper sides 25 of the side walls 22 of the basket 20 in each lower case, wherein on the upper side 25 of at least one side wall 22 of the basket 20 in each lower case a coding body 26 is arranged that protrudes beyond this upper side 25 of this side wall 22 and on the lower side bottom 24 of at least one side wall 23 of the basket 21 in each upper case a coding body receptacle 27 is formed, wherein the coding body 26 can only be inserted into the coding body receptacle in a single stacking position 27 enough so that the baskets 20, 21 are stacked on top of each other.

[0040]Therefore, the stacked arrangement of the baskets in a stacking position is only possible if the coding body 26 can be inserted sufficiently into the coding body housing 27. This can be achieved by various measures. For example, it may be provided that the coding body 26 is the only coding body 26 of the lower basket 20 and the coding body housing 27 is the only coding body housing 27 of the upper basket 21. However, It is also possible that the coding body housing 27 is the only opening on the underside 24 of the side walls 23 of the upper basket 21 into which the coding body 26 can be sufficiently pushed or even fitted. This can be achieved both by the appropriate shape of the coding body 26 and the coding body housing 27 or simply by the size of the opening cross section of the coding body housing 27 relative to the cross-sectional area 35 of the coding body 26. In such configuration forms there can then be several openings in the underside 24 of the side walls 23 of the upper basket 21, precisely only one of these openings can be used as encoder body receptacle 27 for the coding body 26 due to a corresponding size or cross-sectional area and/or shape.

[0041]The basket arrangement shown in Figure 1 by way of example, consisting of the base basket 1 and the superimposed part 2 fixed to it by means of the connecting brackets 3, can constitute in this respect both a lower basket 20 as an upper basket 21. These reference numerals have already been correspondingly introduced in Figures 1 and 2. Therefore, it can be provided that the lower basket 20 has a base basket 1 and an overlay 2 and connecting brackets 3, where the base basket 1 has the basket bottom 4 of the lower basket 20 and the side walls 5 of the base basket 1 and on the side walls 5 of the base basket 1 and on the superimposed piece 2 are housing recesses 6, 7 are formed in each case for the connection supports 3, where the superimposed piece 2 is fixed to the base basket 1 in a manner distanced from the base basket 1 by means of the connection supports 3 arranged in the accommodation recesses 6, 7, and the side walls 22 of the lower basket 20 are formed by the side walls 5 of the base basket 1, the overlay 2 and the connecting brackets 3, and the coding body 26 is arranged on an upper side 25 of the overlay 2 pointing away from the base basket 1. Reference numerals 22 and 23 are already shown correspondingly in Figure 1 to illustrate that if the basket arrangement of Figure 1 is used as a lower basket 20 or as an upper basket 21, the side walls 22 of the lower basket 20 or the side walls 23 of the upper basket 21 are in each case formed by the side walls 5 of the respective base basket 1 and of the respective superimposed piece 2, as well as by the respective connection brackets 3. In this case, the coding body 26 of the lower basket 20 is then arranged on the upper side 25 of the side wall 22 of the lower basket 20 and, therefore, on the upper side 25 of the overlay 2 of the lower basket 20. Instead, the coding body receptacle 27 is then formed in these cases on the lower side 24 of at least one side wall 5 of the base basket 1 of the upper basket 21.

[0042]In preferred configuration forms, such as the one also shown in this case, it is provided that the coding body 26 is fixed or can be fixed in one of the accommodation recesses 7 for the connection supports 3. It is also favorable that, as is also implemented here, one, preferably exactly one or, in other words, only one, of the receptacles 6 for the connection supports 3 forms the coding body receptacle 27.

[0043]In principle, it is conceivable that the coding body 26 is fixedly fixed to the respective upper side 25 of the side walls 22 of the basket 20 in each lower case. However, preferred configuration forms, such as those shown in this case, provide that the coding body 26 can be fixed to the upper side 25 of the side wall 22 of the basket 20 in each lower case by means of a device of fixation 28 non-destructively separable. The fixing device 28 is preferably configured for tool-free fixing of the coding body 26 on or on the upper side 25 of the side wall 22 of the basket 20 in each lower case. Preferably it is also provided that the fixing device 28 is configured to be separated without tools from the upper side 25 of the side wall 22 of the basket 20 in each lower case. Although there are other possibilities of designing the fixing device 28, for example, in the form of bayonet locks, threaded connections and the like, preferred configuration forms, such as those shown here, however, provide that the body of coding 26 can be fixed or is fixed by means of a snap-fit connection 29 to or on the upper side 25 of the side wall 22 of the basket 20 in each lower case.

[0044]The coding body 26 implemented in this case in this exemplary embodiment is shown individually in Figures 17, 18 and 19. Figure 17 shows a side view, Figure 18 a top view and Figure 19 shows the section along the cutting line F-F of Figure 18. In this exemplary embodiment, the coding body 26 is fixed to the upper side 25 of the side wall 22 of the basket 20 in each lower case by means of a connection of snap fit 29. The elastic hooks 30 implemented for this purpose on the coding body 26 in the embodiment examples shown here can be clearly seen in Figures 17, 18 and 19. In the first embodiment example, these hooks Elastics 30 engage in corresponding notches 31 in the accommodation recesses 6 of the insert 2 to form the snap-on connection 29 and therefore for fixing to the upper side 25 of the basket 20 in each lower case. The notches 31 can be clearly seen in figures 9 and 11, for example.

[0045]These snap-in connections 29 are fixing devices 28 that allow the coding body 26 to be fixed and released non-destructively and without the use of tools.

[0046]It will now be explained, with reference to Figures 20 to 24, by means of the first embodiment example, how it can be ensured by means of the coding body 26 and the corresponding coding body housing 27 that the two or more baskets 20 , 21 stackables can only be stacked on top of each other in a single stacking position. In the example shown here, this is achieved because there is only one coding body housing 27 per basket 20 or 21 into which the coding body 26 can be sufficiently inserted. In the variants shown here, exactly one of the receiving recesses 6 is provided with an opening cross section 34 so large that the coding body 26 can be sufficiently inserted into it. Figure 20 shows a top view of a base basket 1 of the upper basket 21. This has a total of eight accommodation spaces 6, figure 21 showing the section G-G, figure 22 the section H-H, figure 23 the section I-I and figure 24 section J-J. By comparing Figures 21, 22, 23 and 24, it is easy to see that seven of the accommodation recesses 65 have a smaller opening cross section 33 and only one of the accommodation recesses 6 has a larger opening cross section 34. , which qualifies this housing space 6 as the only housing of coding body 27.

[0047]Figure 25 now shows a section through an arrangement with the two baskets 20 and 21 stacked on top of each other of the first embodiment in the area of the coding body 26. The only possible stacking position is shown in which the coding body 26 has penetrated the coding body housing 27 to the corresponding extent. The section according to Figure 25 also illustrates once again that, in this first embodiment, both the lower basket 20 and the upper basket 21 are each composed of a base basket 1, the corresponding overlay 2 and the connection supports 3. The side walls 22 and 23 of the lower basket 20 and the upper basket 21 are also formed by the corresponding side walls 5 of the respective base basket 1, the respective overlays 2 and the respective connection supports 3.

[0048]Figure 26 shows area K of Figure 25, enlarged. In this figure 26 it can now be clearly seen that the opening cross section 34 of the coding body housing 27 is so large that the coding body 26 fits there with its cross sectional area 35.

[0049]Figure 27 now shows, by way of example, a fragment corresponding to Figure 26, which shows what happens when an attempt is made to stack the two baskets 20 and 21 on top of each other in a different stacking position. In this case, the coding body 26 encounters a receiving recess 6. However, its opening cross section 33 is so small that the coding body 26 does not fit into this small opening cross section 33 with its area of cross section 35. The collision identified by reference 36 thus occurs, so that these baskets 20 and 21 cannot be stacked on top of each other in this position, which differs from the only possible stacking position.

[0050]Figures 28 to 30 now show a second embodiment according to the invention, in which the lower basket 20 and the upper basket 21 each consist only of a base basket 1. Correspondingly, the side wall 22 of the lower basket consists solely of the side wall 5 of the base basket 1, and the side wall 23 of the upper basket 21 also consists solely of the side wall 5 of the corresponding base basket 1. In this second embodiment, the notches 31 are formed in the corresponding housing recess 6 of the side wall 5 of the base body 1 to form the snap-fit connection 29 with the coding body 26.

[0051]Figure 28 again shows in the corresponding sectional representation the situation in which the two baskets 20 and 21 are stacked on top of each other in the only possible stacking position. The coding body 26 can in this case again penetrate to the corresponding extent into the housing of the coding body 27. The area L of Figure 28 is again shown enlarged in Figure 29. Figure 30 again shows the situation in which attempts in vain to stack the upper basket 21 on top of the lower basket 20 in a stacking position other than the only possible one. In this case shown in Figure 30, due to the smaller opening cross section 33 of the receiving gap 6, the situation again arises that the coding body 26 cannot penetrate this receiving gap 6, so that Stacking on top of each other is not possible in this position due to the collision 36 of the baskets 20 and 21.

[0052]It is useful for people who stack the baskets 20 and 21 on top of each other to be able to easily recognize the position of the coding body 26. A technical means for this can be implemented by designing the coding body 26 in a different color than of the side wall 22 of the lower basket 20 in which it is arranged. This way, the person stacking the baskets on top of each other can easily see which direction the baskets should be stacked on top of each other.
