Description

[Technical Field]

[0001] The present invention provides A base basket, an attachment part, and a connecting support element, the base basket having a basket bottom and a sidewall; a receiving portion for the connecting support element is formed in each of the side wall portion and the attachment part; The present invention relates to a basket assembly in which the attachment part is fixed or securable to the base basket while spaced apart from the base basket by the connecting support element which is releasably fixed to the receiving portion. [Background technology]

[0002] A common type of basket assembly has been proposed (see, for example, Patent Document 1). This is known as a utensil-requiring basket. It is a modular basket having a base basket and an attachment part, with the attachment part and the base basket connected to each other via connecting support elements. Connecting support elements of different lengths are used to form a modular basket or basket assembly in which the base basket and the attachment part are fixed to each other at different intervals. This is used as a type of modular system in which the overall height of the modular basket or basket arrangement can be adapted to the objects stored inside the basket arrangement or modular basket.

[0003] According to the document, the connecting support elements are fastened to the receiving parts of the base basket and the attachment part by snap-fitting, which has the disadvantage that such snap-fitting is often difficult to release and that replacing the connecting support elements or substituting connecting support elements with connecting support elements of different lengths can be relatively costly. [Prior art documents] [Patent documents]

[0004] [Patent Document 1] Austrian Utility Model Registration Publication AT 8270U1 Summary of the Invention [Problem to be solved by the invention]

[0005] The object of the present invention is to propose a remedy in this regard. [Means for solving the problem]

[0006] Based on the general basket assembly, the basket assembly according to the invention can be provided with the following features for this purpose: each of the connecting support elements: 1st a rotational locking mechanism that releasably locks the base basket to one of the receiving portions of the side wall of the base basket; R, and, Second a rotational locking mechanism that releasably locks the attachment part to one of the receiving portions; R .

[0007] Therefore, according to the present invention, the fixing or locking of the connecting support elements is realized by a rotational locking mechanism in the receiving parts of the base basket and the side wall of the attachment part, rather than by a snap-type fixing as in the prior art. Such a rotational locking mechanism can be designed to be easily unlockable, so that the connecting support elements can be replaced much more easily compared to the prior art. Preferably, the connecting support elements can be rotated in both directions between the locked and unlocked positions by the rotational locking mechanism in each of the receiving parts.

[0008] The fastening system allows the transition between the fastened and unlocked positions by a simple rotation of each of the connecting support elements. In the fastened position, the connecting support elements are attached or fixed to the respective receiving parts. In the unlocked position, the connecting support elements are removed from the respective receiving parts of the attachment part or the base basket or its side wall.

[0009] In principle, the rotational locking mechanism has a stop at each of the locking position and the unlocking position, and cannot be rotated beyond that position. In such an embodiment, the connecting support element reciprocates between the locking position and the unlocking position to unlock, release, or lock the rotational locking mechanism. However, the basket assembly according to the present invention is particularly easy to handle if each of the rotational locking mechanisms has a sequence of alternating locking and unlocking positions, and each of the connecting support elements can be successively transitioned to one locking position and one unlocking position by further rotating in a single rotational direction. In this preferred embodiment, it is not important which rotational direction the connecting support element uses to transition from the locking position to the unlocking position, or vice versa.

[0010] The attachment part is preferably an attachment frame, which is a simple frame without a bottom that surrounds an opening. However, for the sake of completeness, it should be noted that the basket assembly according to the invention may also be composed of several baskets or a base basket that are fixed to one another by connecting support elements. In this case, the attachment part is an attachment basket that has a basket bottom and side walls, and the receiving part of the attachment basket is located on the side walls.

[0011] In a preferred embodiment of the basket arrangement according to the invention, the rotational locking mechanism is recessed and fixed in each of the receiving parts. In this sense, the receiving parts may be designed as longitudinally extending receiving channels in both the attachment part and the side wall of the base basket. Because the rotational locking mechanism is recessed in the receiving parts, the connecting support elements must be slightly pressed into each of the receiving parts to be fixed. This allows the connecting support elements to abut against the parts of the base basket or the side wall of the attachment part that surround the receiving parts. This is advantageous for the overall stability of the basket assembly according to the invention.

[0012] Further features and details of preferred embodiments of the present invention are explained below using exemplary embodiments, it being pointed out that the individual features of the embodiments are not necessarily combined with other features of the exemplary embodiments, but can be combined in other ways or individually with the basic idea of ​​the present invention.

[0014] FIG. 1 shows a perspective view of one embodiment of a basket assembly according to the present invention. The basket assembly includes a base basket 1, an attachment part 2, and connecting support elements 3. The base basket 1 has a basket bottom 4 and side walls 5. The side walls 5 and the attachment part 2 are formed with first and second receiving portions 6 and 7, respectively, for the connecting support elements 3. The attachment part 2 is fixed to the base basket 1 while spaced apart from the base basket 1 by the connecting support elements 3, which are releasably fixed to the first and second receiving portions 6 and 7. According to the present invention, each of the connecting support elements 3 is releasably fixed to one of the first receiving portions 6 of the side walls 5 of the base basket 1 and to one of the second receiving portions 7 of the attachment part 2 by a rotational fixing mechanism 8. As mentioned above, it is preferred that the connecting support element 3 is fixed or fixable in its respective first receiving portion 6 or second receiving portion 7 by the respective rotational fixing mechanism 8 so as to be rotatable clockwise and counterclockwise between a fixed position and an unlocked position.

[0015] The basket assembly according to the present invention is also referred to as a modular basket or simply a modular basket. The basket assembly is constructed by assembling a base basket 1 and an attachment part 2 via connecting support elements 3. By using connecting support elements 3 of different lengths, the attachment part 2 can be attached to the base basket 1 at different heights or different intervals from the base basket 1. In this way, the basket assembly according to the present invention can be easily adapted to the size or height of the objects to be stored therein. The basket assembly according to the present invention can be used not only as a tableware basket for glasses or plates, but also as a so-called industrial basket for storing and storing various industrial objects therein, or simply as a storage and / or transport basket. The concept of a basket can be replaced with the concept of a box, i.e., a box assembly, a modular box, or simply a modular box.

[0016] If the basket assembly is used not only for storage and / or transport but also for washing, rinsing and / or drying the objects stored therein, the basket bottom 4 of the base basket 1 is preferably of grid-like design or at least provided with openings, as known per se. The side walls 5 of the base basket may also have such openings or may also be of grid-like design.

[0017] The base basket 1, the attachment part 2 and the connecting support element 3, as well as the sign element 26, are preferably made of plastic, which may be, for example, an injection-molded product. Preferably, the basket assembly is made entirely of plastic.

[0018] In order to fasten the base basket 1 to the attachment part 2 as quickly as possible, in a preferred embodiment of the present invention, the connecting support element 3 can be simultaneously releasably fastened to one of the first receiving portions 6 of the side wall portion 5 of the base basket 1 and one of the second receiving portions 7 of the attachment part 2 by being rotated in one direction by each of the rotational fastening mechanisms 8. The connecting support element 3, which has an elongated shape, is preferably rotated about its longitudinal axis.

[0019] 2 shows the base basket 1, the attachment part 2, and the connecting support element 3 in an exploded state. Accordingly, Fig. 2 shows the connecting support element 3 in an unlocked state, where it has been removed or withdrawn from the first receiving portion 6 of the side wall portion 5 of the base basket 1 and the second receiving portion 7 of the attachment part 2. In this state, the connecting support element 3 can be replaced with another connecting support element 3, in particular a connecting support element 3 of a different length, in order to secure the attachment part 2 at a different height or at a different interval from the base basket 1.

[0020] In this case, as in the other preferred embodiments, the attachment part 2 is designed as an attachment frame. It surrounds the central opening in the form of a frame, but does not have a bottom. However, unlike this embodiment, the basket assembly according to the invention may also be an attachment basket with a basket bottom and side walls as the attachment part 2, and the receiving part of the attachment basket may be located on the side walls. The attachment basket may, for example, have the same design as the base basket 1. In this other embodiment, the basket assembly according to the invention may also comprise several baskets stacked on top of each other and fixed at a distance from each other by connecting support elements 3.

[0021] Of course, the number of connecting support elements 3 per basket assembly may vary. It is not necessary to provide two connecting support elements 3 for each side wall 5 of the base basket 1, as in the present embodiment. The arrangement of the connecting support elements 3 on the side wall 5 and attachment part 2 of the base basket 1 may also differ from that of the present embodiment. For example, the connecting support elements 3 may be arranged at the corners of the side wall 5 and attachment part 2 of the base basket 1, or may be arranged in the center of each side wall 5.

[0022] The optional marking element 26 and its function are described below.

[0023] Optionally, a label holder 16 may be provided, as shown in Figures 2, 3 and 4, which in this embodiment is attached to one of the side walls 5 of the base basket 1, for example by a clip 17.

[0024] FIG. 5 shows a top view of the basket assembly of FIG. 1. FIG. 6 shows a longitudinal cross-sectional view taken along section line AA in FIG. 5. FIG. 7 shows an enlarged view of portion B in FIG. 6. FIG. 8 shows a cross-sectional view of only the base basket 1, similar to FIG. 6. FIG. 9 shows a cross-sectional view of only the attachment part 2, similar to FIG. 6. FIG. 10 shows an enlarged view of portion C in FIG. 8. FIG. 11 shows an enlarged view of portion D in FIG. 9. FIGS. 12-14 show the connecting support element 3 used in this embodiment of the present invention, and FIG. 14 shows a cross-sectional view taken along section line EE. FIGS. 15 and 16 show the rotational locking mechanism 8 in the first receiving portion 6 and the second receiving portion 7. FIG. 15 shows the connecting support element 3 in an unlocked position, removed or withdrawn from the first receiving portion 6 or the second receiving portion 7, respectively. Figure 16 shows the connecting support element 3 in a fixed position, secured to either the first receiving portion 6 or the second receiving portion 7 by the rotational locking mechanism 8. As in this embodiment, the rotational locking mechanism 8 in the first receiving portion 6 of the side wall portion 5 of the base basket 1 is preferably identical to the rotational locking mechanism 8 in the second receiving portion 7 of the attachment part 2. Figures 15 and 16 show the rotational locking mechanisms 8 in both the first receiving portion 6 of the side wall portion 5 and the second receiving portion 7 of the attachment part 2.

[0025] As realized in this embodiment, it is preferable that the rotational locking mechanism 8 is formed of a first rotational locking portion 9 formed on the connecting support element 3 and a second rotational locking portion 10 formed on the first receiving portion 6 or the second receiving portion 7. In the present invention, it is preferable that the first rotational locking portion 9 formed on the connecting support element 3 can be inserted into the second rotational locking portion 10 formed on the first receiving portion 6 or the second receiving portion 7 in the locked position, and can be removed from the second rotational locking portion 10 formed on the first receiving portion 6 or the second receiving portion 7 in the unlocked position. This is realized in this embodiment.

[0026] 6 and 7 it can be seen that the rotation and locking mechanism 8 is arranged to some extent sunken or recessed in relation to both the first receiving portion 6 of the side wall 5 and the second receiving portion 7 of the attachment part 2. This has the advantage that each of the connecting and supporting elements 3 is adjacent to the rotation and locking mechanism 8 and is supported by the walls surrounding the first receiving portion 6 and the second receiving portion 7. The sunken arrangement of the rotation and locking mechanism 8 may also be designed in a different way from this embodiment.

[0027] The rotational fixing mechanism 8, which is identical in each of the first receiving portions 6 and the second receiving portions 7 in the other embodiments and in this embodiment, as implemented here as well, enables each of the connecting support elements 3 to be simultaneously releasably or unfastenably fixed to one of the first receiving portions 6 of the side wall portion 5 of the base basket 1 and one of the second receiving portions 7 of the attachment part 2.

[0028] As described above, the rotational locking mechanism 8 may be configured to have stops in both the locked and unlocked positions. In this embodiment, the connecting support element 3 can then rotate clockwise and counterclockwise only between the unlocked and locked positions. As realized in this embodiment, each of the rotational locking mechanisms 8 has a continuum of alternating locking and unlocking positions, and each of the connecting support elements 3 can transition to one of the locked and unlocked positions by rotating in a single rotational direction. Generally, the rotational locking mechanism 8 is also referred to as a locking unit or a locking device. The connecting support element 3 is also referred to as an upright, connector, or intermediate piece. These are preferably designed to be elongated or extend longitudinally. The first rotational locking portions 9 for forming the rotational locking mechanism 8 according to the present invention are appropriately disposed on both ends of the connecting support element 3. The connecting support element 3 is preferably provided in a variety of lengths.

[0029] The rotational locking mechanism 8 used in the basket assembly according to the present invention can, in principle, be designed in a variety of different ways. For example, it can be a screw or threaded locking mechanism, a bayonet-type locking mechanism, or equivalent. A preferred embodiment of the present invention provides for no longitudinal or axial stroke of the connecting support element 3 when the connecting support element 3 is rotated between the locked and unlocked positions, i.e., the attachment part 2 always maintains the same distance from the base basket 1 during locking or unlocking. This can be achieved, for example, in a variant of the preferred embodiment, by providing a second rotational locking portion 10 formed on the first receiving portion 6 or the second receiving portion 7 with at least one bead 11. The second rotational locking portion 9 formed on the connecting support element 3 with at least one pair of clamping elements 13, 14 defining at least a bead receiving portion 12. The bead 11 is preferably elastically clamped between the clamping bodies 13, 14 in the locked position of the bead receiving portion 12. In this preferred embodiment, the second rotational locking portion 10 formed in the first receiving portion 6 or the second receiving portion 7 is a series of beads 11 arranged in one plane. The first rotational locking portion 9 formed in the connecting support element 3 includes at least one pair of clamp bodies 13, 14, preferably multiple pairs corresponding to the number of beads 11, defining the bead receiving portion 12. Preferably, all of the beads 11 can be clamped between the clamp bodies 13, 14 at the fixed positions of the bead receiving portion 12. This allows for a continuity of alternating fixed and unlocked positions, and each connecting support element 3 can be transitioned to one fixed position and one unlocked position by further rotating in a single rotational direction. This makes it irrelevant how the connecting support element 3 is rotated to transition from the fixed position to the unlocked position, or vice versa. In this embodiment, the beads 11 arranged in one plane are shown in Figures 6 to 11 and Figures 15 and 16. As a result of this arrangement of the beads 11 in one plane, no stroke is generated in the longitudinal direction of each of the connecting support elements 3 during locking and unlocking.

[0030] In this embodiment, the beads 11 are arranged in a square shape. However, this is only one embodiment. For example, other arrangements with different numbers of beads 11 are possible to achieve a flat arrangement of beads 11.

[0031] 12 to 14 are referenced for the first rotational locking portion 9 of the connecting support element 3. In particular, the longitudinal cross-sectional view of FIG. 14 clearly shows that each of the first rotational locking portions 9 has bead receiving portions 12 defined by pairs of two clamping elements 13 and 14, the number of which corresponds to the number of beads 11 of the second rotational locking portion 10. The clamping elements 13 and 14 allow each of the beads 11 to be clamped, preferably elastically, in the bead receiving portions 12. Between the clamping elements 13 formed in the end regions of each of the connecting support elements 3, there is an intermediate region 19 where no bead receiving portion 12 is present. The intermediate region 19 is located closer to the rotation axis 32 than the clamping elements 13. The rotation axis 32 is an axis along which each of the connecting support elements 3 can rotate from the unlocked position to the locked position, or vice versa.

[0032] The clamping elements 14, seen in the longitudinal direction of the connecting support elements 3, which indicates the direction of the center of each of the connecting support elements 3, may in this embodiment, but need not necessarily, be formed as a plate-like structure, which in this case advantageously has at least one free space 18. The function of the free space 18 will be explained in more detail below.

[0033] Before the connecting support element 3 can be rotated from the unlocked position to the locked position, it must first be pushed into the first or second receiving portion 6 or 7, respectively, and then its first rotation locking portion 9 must be engaged so as to rotate together with the second rotation locking portion 10 of the first receiving portion 6. This pushing and unscrewing is performed in the position shown in FIG. 15. In this position, the intermediate region 19 is moved past the beads 11 until the clamping element 13 is threaded between the beads 11, allowing rotational movement about the rotation axis 32. Starting from the state shown in FIG. 15, when the connecting support element 3 is rotated about the rotation axis 32, the clamping elements 13 and 14 engage with the beads 11, respectively, which then rest in the bead receiving portions 12 between the clamp bodies 13 and 14. Further rotation then leads to the locked position shown in FIG. 16, where the beads 11 are held in the bead receiving portions 12 between the clamp bodies 13 and 14, preferably by an elastic clamp. This position is clearly shown in FIGS.

[0034] In contrast to this embodiment, the first and second rotary locking parts 9, 10 may also be configured inversely or interchangeably, such that the first rotary locking part 9 of the connecting support element 3 comprises a corresponding bead 11 and the second rotary locking part 10 of the side wall 5 or the first or second receiving part 6 or 7 of the attachment part 2 comprises a bead receiving part 12 with corresponding clamping elements 13 and 14.

[0035] In a preferred embodiment of the invention, as is also implemented here, drainage openings 15 are formed in each of the connecting and supporting elements 3 in order to drain water that has entered the first receiving part 6 or the second receiving part 7 to which each of the connecting and supporting elements 3 is fixed. This serves to ensure that water that may enter the first receiving part 6 or the second receiving part 7, for example during a washing or rinsing process, does not accumulate in the respective rotation and fixing mechanism 8. For this purpose, the drainage openings 15 are provided in the connecting and supporting elements 3 in this embodiment. Water that has entered the first receiving part 6 or the second receiving part 7 passes through the drainage openings 15 and through the free space 18 and is discharged from above, so that it does not accumulate in the first receiving part 6 or the second receiving part 7 via the connecting and supporting elements 3 or their rotation and fixing mechanism 8.

[0036] The indicator element 26 shown in Figures 1 and 2 and 6 and 7 is an optional feature of the present invention. In a preferred embodiment, it functions in conjunction with the indicator element receiver 27 to ensure that, in an assembly of at least two stackable baskets 20 and 21, the baskets can only be stacked in a single stacking position. In other words, the indicator element 26, together with the indicator element receiver 27, prevents two baskets from being stacked on top of each other in different stacking positions. A stacking position for two baskets is one in which the baskets are stacked on top of each other along their side walls, with their side walls aligned with each other or congruent with each other when viewed from above. A stacking position is not one in which the baskets are stacked on top of each other, for example, crisscross or across.

[0037] In a preferred variation of the present invention, at least two stackable baskets 20, 21 each have a basket bottom 4 and side walls 22, 23, and in the stacked baskets 20, 21, a lower portion 24 of each side wall 23 of the upper basket 21 is located on an upper portion 25 of each side wall 22 of the lower basket 20. A marking element 26 is disposed on each of the lower baskets 20, protruding beyond the upper portion 25 of the at least one side wall 22. A marking element receiving portion 27 is formed in the lower portion 24 of the at least one side wall 23 of each of the upper baskets 21. The marking element 26 can be inserted sufficiently deeply into the marking element receiving portion 27 so that the baskets 20, 21 can only be stacked on top of each other in a single stacking position.

[0038] Therefore, assembly of the stacked baskets in the stacked position can only be achieved if the marker element 26 is inserted sufficiently deeply into the marker element receiving portion 27. This can be achieved in various ways. For example, the marker element 26 may be the only marker element 26 of the lower basket 20, and the marker element receiving portion 27 may be the only marker element receiving portion 27 of the upper basket 21. The marker element receiving portion 27 may be the only opening in the lower portion 24 of the side wall 23 of the upper basket 21 so that the marker element 26 is inserted or fitted sufficiently deeply. This can be easily achieved by appropriately configuring the marker element 26 and the marker element receiving portion 27, for example, by adjusting the size of the cross-sectional opening of the marker element receiving portion 27 relative to the cross-sectional area 35 of the marker element 26. In such an embodiment, multiple openings are provided in the lower portion 24 of the side wall 23 of the upper basket 21, and only one of the openings is applicable as the marker element receiving portion 27 for the marker element 26 due to its corresponding size, cross-sectional area, and / or shape.

[0039] The basket assembly according to the present invention illustrated in FIG. 1 comprises a base basket 1, which constitutes a lower basket 20 and an upper basket 21, and an attachment part 2 fixed thereto by a connecting support element 3. The corresponding reference numerals have already been shown in FIGS. 1 and 2. The lower basket 20 comprises the base basket 1, the attachment part 2, and the connecting support element 3. The base basket 1 comprises a basket bottom 4 of the lower basket 20 and a side wall 5 of the base basket 1. A first receiving portion 6 for the connecting support element 3 is formed in the side wall 5 of the base basket 1, and a second receiving portion 7 for the connecting support element 3 is formed in the attachment part 2. The attachment part 2 is fixed to the base basket 1 at a distance from the base basket 1 by the connecting support element 3 arranged in the first receiving portion 6 and the second receiving portion 7. The side wall 22 of the lower basket 20 is formed by the side wall 5 of the base basket 1, the attachment part 2, and the connecting support element 3. 1 is configured as a lower basket 20 or an upper basket 21, and each of the side wall portions 22 of the lower basket 20 or the side wall portions 23 of the upper basket 21 is configured by the side wall portions 5 of the base basket 1, each of the attachment parts 2, and each of the connecting support elements 3. In this case, the label element 26 of the lower basket 20 is arranged on the upper portion 25 of the side wall portion 22 of the lower basket 20, and therefore on the upper portion 25 of the attachment part 2 of the lower basket 20. Meanwhile, in this case, a label element receiving portion 27 is formed on the lower portion 24 of at least one side wall portion 5 of the base basket 1 of the upper basket 21.

[0040] In a preferred embodiment, as realized here, the marking element 26 is fixed or fixable to the second receiving portion 7 for the connecting support element 3. As also realized here, one, single or only first receiving portion 6 for the connecting support element 3 constitutes the marking element 27.

[0041] In principle, the marker element 26 may be fixed to the upper portion 25 of each of the side walls 22 of the lower basket 20. In a preferred embodiment, the marker element 26 may be fixed to the upper end or upper portion 25 of each of the side walls 22 of the lower basket 20 by a fixing mechanism 28 that can be non-destructively released. The fixing mechanism 28 is preferably designed to fix the marker element 26 to the upper end or upper portion 25 of each of the side walls 22 of the lower basket 20 without using tools. The fixing mechanism 28 is preferably designed to be removed from the upper portion 25 of each of the side walls 22 of the lower basket 20 without using tools. For example, while the fixing mechanism 28 can be configured in the form of a bayonet-type fixing mechanism, a screw-type fixing mechanism, or the like, in a preferred embodiment, the marker element 26 is fixed or fixable to the upper end or upper portion 25 of each of the side walls 22 of the lower basket 20 by a snap fixing mechanism 29.

[0042] The sign element 26 implemented in this embodiment is shown individually in Figures 17, 18, and 19. Figure 17 shows a side view, Figure 18 shows a top view, and Figure 19 shows a cross-sectional view along section line FF in Figure 18. In this embodiment, the sign element 26 is secured to the upper part 25 of each side wall portion 22 of the lower basket 20 by a snap-fastening element 29. In this embodiment, resilient hooks 30 implemented on the sign element 26 for this purpose are clearly shown in Figures 17, 18, and 19. To form the snap-fastening mechanism 29 and thereby secure it to each upper part 25 of the lower basket 20, the resilient hooks 30 are secured to or engaged with corresponding undercuts 31 in the first receiving portion 6 of the attachment part 2 in this embodiment. The undercuts 31 are clearly shown, for example, in Figures 9 and 11.

[0043] The snap fastening element 29 is a fastening mechanism 28 that allows both fastening and unlocking of the sign element 26 non-destructively and without the need for tools.

[0044] Next, referring to FIGS. 20-24, we will explain how the labeling elements 26 and corresponding labeling element receiving portions 27 ensure that two or more stackable baskets 20, 21 can be stacked together in only one stacking position. In this embodiment, this is achieved by providing a single labeling element receiving portion 27 for each basket 20 or 21, into which the labeling element 26 can be inserted sufficiently deeply. In this embodiment, exactly one of the first receiving portions 6 has a large opening cross-sectional area 34 so that the labeling element 26 can be inserted sufficiently deeply into it. FIG. 20 shows a top view of the base basket 1 of the upper basket 21. It has a total of eight first receiving portions 6, with cross-sections along section line GG shown in FIG. 21, section line HH shown in FIG. 22, section line II shown in FIG. 23, and section line JJ shown in FIG. 24. Comparing Figures 21, 22, 23 and 24, seven receiving portions 65 have small opening cross-sectional areas 33, and only one first receiving portion 6, which serves as the only sign element receiving portion 27, has a large opening cross-sectional area 34.

[0045] 25 shows a cross-sectional view of an assembly in which two baskets 20 and 21 are stacked on top of each other in the region of the sign element 26. The only possible stacking position is shown, with the sign element 26 passing through the sign element receiving portion 27. The cross-sectional view of FIG. 25 once again shows that in this embodiment, the lower basket 20 and the upper basket 21 are each made up of a base basket 1, a corresponding attachment part 2, and a connecting support element 3. Accordingly, the side walls 22 and 23 of the lower basket 20 and the upper basket 21 are made up of the corresponding side walls 5 of each base basket 1, each attachment part 2, and each connecting support element 3.

[0046] Figure 26 is an enlarged view of portion K of Figure 25. In Figure 26, it is clear that the opening cross-sectional area 34 of the sign element receiving portion 27 is so large that a sign element 26 having the cross-sectional area 35 thereof can fit therein.

[0047] Figure 27 illustrates a detail corresponding to Figure 26 and shows what happens when an attempt is made to stack two baskets 20 and 21 on top of each other in a different stacking position. In this case, the marking element 26 faces the first receiver 6. However, its opening cross-sectional area 33 is small, so that the marking element 26 with its cross-sectional area 35 does not fit into the small opening cross-sectional area 33. Therefore, a collision occurs, as indicated by the reference numeral 36, and the baskets 20 and 21 cannot be stacked on top of each other in this position, which is outside the only possible stacking position.

[0048] It is helpful for workers who alternately stack the upper baskets 20 and the lower baskets 21 if the position of the marking elements 26 can be easily recognized. This is achieved by a technical measure in which the marking elements 26 are designed in a different color from the side wall 22 of the lower basket 20 on which they are located. In this way, workers who stack the baskets can easily see how the baskets are stacked. [Explanation of symbols]
