Definitions

  • the invention relates to a storage trough or a storage box made of sheet metal, in particular with a viewing opening, in which or at least the transverse walls have a vertical wall surface and a stacking edge adjoining it at the top, which is formed by a bead which is integrally connected to these folds, and which has a substantially horizontal stacking surface formed by the upper corrugation wall and an approximately vertical boundary surface consisting of the fold for receiving a further storage trough or a further storage box, a hollow profile being formed on the outside on the part of the stacking edge which forms the vertical boundary surface, which has a wall section running obliquely towards the box wall, stiffening with an angled support section against the box wall, and with this, e.g. B. is firmly connected by welding.

  • a disadvantage of the generic stackable storage boxes of the known type is that the hollow sections shielding the actual stacking edge from the outside have a relatively large projection, so that the storage space required for the adjustment of the individual storage boxes must be considerably larger on all sides than that of the box bottom limited box floor space.

This sheet metal doubling 29 is then first folded at an acute angle, as shown in FIG. 5, and then rolled into the shape shown in FIG. 3. It is obvious that this measure gives the stiffening edge 28 formed on the rear wall 7 high dimensional stability. It is also important that the rear wall 7 at the level of the stacking surface 17 of the stacking edge 16 of the transverse walls 10 and 11 of a compression 30 directed outwards at least by the sheet thickness, as can be seen from FIGS.

  • the angled tongues 32 engage in the spacing gap 25 between the vertical boundary surface 18 of the stack edge 16 and the wall part 21 of the hollow profile 20 which is parallel thereto and are firmly connected to them by spot welding.
  • end wall 5 can also be provided with a stiffening edge 34 rolled outwards. If necessary, this can be stabilized in a similar manner by sheet metal doubling, as is shown in FIGS. 3 to 5 for the stiffening edge 28 of the rear wall 7.
  • the storage trough 1 Since the front wall 5 in the exemplary embodiment of a storage trough 1 shown is only about half the height of the rear wall 7 and the two transverse walls 10 and 11, the storage trough 1 also has a viewing or engaging opening at this point when a plurality of storage troughs 1 are stacked on top of one another in the manner shown in FIG.

Storage tray or storage crate (1) of sheet metal, more especially with a viewing opening, in which at least the transverse walls (10, 11) comprise a vertical wall surface and a stacking rim (16) attached to the top thereof, which rim is formed by a bead (19) and turned-over edges in one piece with the latter, and which comprises a substantially horizontal stacking surface (17) formed by the upper bead wall and a substantially vertical external surface (18) consisting of the turned-over edge and for receiving an additional storage tray or crate (1), a hollow section member (20) being formed externally on that part of the stacking rim (16) which forms the vertical external surface (18), which hollow section member comprises a wall section (22) obliquely of the tray or crate wall, is supported with a bent-over support section (23) and with a stiffening action against the tray or crate wall (10, 11) and is connected fast to the latter, for example, by being welded thereon, characterised in that the hollow section member (20) comprises a wall section (21) parallel to the edge forming the vertical boundary surface (18) of the stacking rim (16), which section (21) is extended approximately to the height of the bottom edge of the bead (19), and that the adjoining wall section (22) extending at an inclination to the tray or crate wall (10, 11) is led from the region of the bottom edge of the bead (19) until against the vertical wall surface and at this position merges into the bent-over support section (23) which extends parallel to the vertical wall surface.

Description

Die Erfindung betrifft eine Lagerwanne oder einen Lagerkasten aus Blech, insbesondere mit Sichtöffnung, bei der bzw. dem mindestens die Querwände eine senkrechte Wandfläche und einen sich oben daran anschließenden Stapelrand aufweisen, der durch eine Sicke und sich einstückig an diese anschließende Abkantungen gebildet wird, und der eine im wesentlichen waagerechte, durch die obere Sickenwand gebildete Stapelfläche und eine etwa senkrechte, aus der Abkantung bestehende Begrenzungsfläche zur Aufnahme einer weiteren Lagerwanne oder eines weiteren Lagerkastens aufweist, wobei außenseitig an den die senkrechte Begrenzungsfläche bildenden Teil des Stapelrandes ein Hohlprofil angeformt ist, das einen schräg zur Kastenwand hin verlaufenden Wandabschnitt aufweist, sich mit einem abgewinkelten Stützabschnitt versteifend gegen die Kastenwand abstützt und mit dieser, z. B. durch Anschweißen, fest verbunden ist.The invention relates to a storage trough or a storage box made of sheet metal, in particular with a viewing opening, in which or at least the transverse walls have a vertical wall surface and a stacking edge adjoining it at the top, which is formed by a bead which is integrally connected to these folds, and which has a substantially horizontal stacking surface formed by the upper corrugation wall and an approximately vertical boundary surface consisting of the fold for receiving a further storage trough or a further storage box, a hollow profile being formed on the outside on the part of the stacking edge which forms the vertical boundary surface, which has a wall section running obliquely towards the box wall, stiffening with an angled support section against the box wall, and with this, e.g. B. is firmly connected by welding.

Stapelbare Lagerwannen oder Lagerkästen dieser Gattung gehören bereits durch das DE-U-1 997 260 bzw. die DE-A-1 786 082 zum Stand der Technik. Sie haben den Vorteil. daß der eigentliche Stapelrand durch das ihn nach außen umgebende Hohlprofil geschützt und damit selbst bei rauhem Betrieb gegen Verbeulen oder Einknicken gesichert wird. Außerdem bewirkt aber das den Stapelrand umgebende Hohlprofil auch noch eine stabilisierende Aussteifung der Kastenwände insgesamt.DE-U-1 997 260 and DE-A-1 786 082 already make stackable storage trays or storage boxes of this type part of the prior art. You have the advantage. that the actual stack edge is protected by the hollow profile surrounding it and is thus secured against buckling or buckling even in rough operation. In addition, however, the hollow profile surrounding the stack edge also brings about a stabilizing stiffening of the box walls as a whole.

Nachteilig bei den gattungsgemäßen stapelbaren Lagerkästen der bekannten Bauart ist jedoch, daß die den eigentlichen Stapelrand nach außen abschirmenden Hohlprofile eine verhältnismäßig große Ausladung haben, so daß der für das Einstellen der einzelnen Lagerkästen notwendige Stauraum nach allen Seiten beträchtlich größer bemessen sein muß als die vom Kastenboden begrenzte Kastengrundfläche. Zwischen zwei nebeneinander aufgestellten Lagerkästen der bekannten Bauart ergeben sich dadurch zwangsläufig verhältnismäßig große, nicht nutzbare Hohlräume.A disadvantage of the generic stackable storage boxes of the known type, however, is that the hollow sections shielding the actual stacking edge from the outside have a relatively large projection, so that the storage space required for the adjustment of the individual storage boxes must be considerably larger on all sides than that of the box bottom limited box floor space. This inevitably results in relatively large, unusable cavities between two side-by-side storage boxes of the known type.

Nachteilig ist ferner, daß die nach außen gewölbte Hohlprofile im Eckbereich eines Kastens nur durch aufwendige Schweiß- oder Lötvorgänge miteinander verbunden werden können, die wiederum zusätzliche Putzarbeiten nach sich ziehen. Außerdem ergeben die Wölbungen beim Zuschnitt des flachen, unverformten Bleches komplizierte Abwicklungsschnitte, die wiederum den Einsatz teurer Schnittwerkzeuge notwendig machen.Another disadvantage is that the outwardly curved hollow profiles in the corner region of a box can only be connected to one another by complex welding or soldering processes, which in turn entail additional cleaning work. In addition, the curvatures when cutting the flat, undeformed sheet result in complicated development cuts, which in turn make the use of expensive cutting tools necessary.

Als besonders nachteilig hat sich bei den bekannten Kästen erwiesen, daß der gegen die Kastenwand zurücklaufende Teil des Hohlprofiles sich im Bereich der Sicke gegen die Kastenwand abstützt. Dadurch ergibt sich im Bereich der Kante, die den Übergang von dem senkrechten Teil der Kastenwand zur Sicke bildet, eine Schwachstelle, die bei Belastung des Stapelrandes durch andere Stapelkästen zu einem tordierenden Abknicken des Stapelrandes führen kann.It has been found to be particularly disadvantageous in the known boxes that the part of the hollow profile which runs back against the box wall is supported against the box wall in the region of the bead. This results in a weak point in the area of the edge which forms the transition from the vertical part of the box wall to the bead, which can lead to a twisting buckling of the stack edge when the stack edge is loaded by other stack boxes.

Die Erfindung bezweckt die Beseitigung dieser Nachteile, Ihr liegt daher die Aufgabe zugrunde, für eine Lagerwanne oder einen Lagerkasten der gattungsgemäßen Art aus Blech eine Raumform zu finden, die trotz ausreichender Sicherung des Stapelrandes gegen Einknicken und Verbeulen sowie unter Aufrechterhaltung einer hohen Gesamtstabilität zu einer Verminderung der größten äußeren Wannen- bzw. Kastenabmessungen relativ zu deren Bodenfläche führt. Die Lösung dieser Aufgabe wird nach der Erfindung dadurch erreicht, daß das Hohlprofil einen zu der die senkrechte Begrenzungsfläche des Stapelrandes bildenden Abkantung parallelen Wandabschnitt aufweist, der sich etwa bis zur Höhe der Unterkante der Sicke erstreckt, und daß der sich daran anschließende schräg zur Kastenwand hin verlaufende Wandabschnitt vom Bereich der Unterkante der Sicke aus bis gegen die senkrechte Wandfläche geführt ist und dort in den abgewinkelten Stützabschnitt übergeht, welcher sich parallel zur senkrechten Wandfläche erstreckt.The invention aims to eliminate these disadvantages, it is therefore the object of finding a spatial shape for a storage trough or a storage box of the generic type made of sheet metal, which despite sufficient securing of the stack edge against buckling and buckling and while maintaining a high overall stability to a reduction the largest outer tub or box dimensions relative to their floor area. The solution to this problem is achieved according to the invention in that the hollow profile has a wall section parallel to the fold forming the vertical boundary surface of the stacking edge, which extends approximately to the height of the lower edge of the bead, and in that the diagonal to the box wall extending wall section is led from the area of the lower edge of the bead to the vertical wall surface and merges there into the angled support section which extends parallel to the vertical wall surface.

Dabei ist es von Vorteil, daß der wesentliche Teil des die Wandungen stabilisierenden Hohlprofils etwa auf gleicher Höhe der unterhalb des Stapelrandes befindlichen Sicke liegt und somit nach außen durch verhältnismäßig breite, ebene Flächen begrenzt werden kann.It is advantageous that the major part of the hollow profile stabilizing the walls lies approximately at the same height as the bead located below the stacking edge and can thus be limited to the outside by relatively wide, flat surfaces.

Zur Vermeidung des Verbeulens oder Einknickens des Stapelrandes bei Einwirkung äußerer Kräfte kann sich auch das im zweiten Anspruch angegebene Neuerungsmerkmal als vorteilhaft erweisen.In order to avoid buckling or buckling of the stack edge under the action of external forces, the innovation feature specified in the second claim can also prove to be advantageous.

Eine weitere Stabilisierungsmaßnahme zum Schutz des Stapelrandes gegen unerwünschte Krafteinwirkungen kann nach der Neuerung auch durch das im dritten Anspruch angegebene Merkmal noch erreicht werden.A further stabilization measure to protect the edge of the stack against undesired forces can also be achieved after the innovation by the feature specified in the third claim.

In vielen Fällen kann es sich als zweckmäßig erweisen, an einer Lagerwanne oder einem Lagerkasten die im vierten und fünften Anspruch vorgeschlagenen Maßnahmen zu treffen.In many cases, it may prove expedient to take the measures proposed in the fourth and fifth claims on a storage trough or a storage box.

In baulicher Hinsicht haben sich nach der Neuerung auch die im sechsten Anspruch vorgeschlagenen Maßnahmen bewährt.In terms of construction, the measures proposed in the sixth claim have also proven their worth after the innovation.

Eine besonders formstabile Ausgestaltung der Lagerwanne oder des Lagerkastens gegen seitliche Krafteinwirkungen und eine Erhöhung der Verwindungssteifigkeit ergibt sich durch neuerungsgemäße Nutzung der in den Ansprüchen 7 und 8 aufgezeigten Maßnahmen.A particularly dimensionally stable configuration of the storage trough or the storage box against the effects of lateral forces and an increase in the torsional stiffness results from the use of the measures indicated in claims 7 and 8 in accordance with the innovation.

Im Sinne einer Stabilisierung der Lagerwanne oder des Lagerkastens wirken sich auch die in den Ansprüchen 9 und 10 angegebenen Merkmale aus, während durch die Maßnahme nach Anspruch 11 der Einsatzbereich für die Lagerwanne oder den Lagerkasten vergrößert werden kann.In terms of stabilizing the storage trough or the storage box, the features specified in claims 9 and 10 also have an effect, while the area of use for the storage trough or storage box can be enlarged by the measure according to claim 11.

In Fig. 1 ist eine stapelfähige Lagerwanne 1 gezeigt, die eine verhältnismäßig große Baubreite 2, eine verhältnismäßig große Bautiefe 3 und eine relativ geringe Bauhöhe 4 haben kann. Die Stirnwand 5, der Boden 6 und die Rückwand 7 der Lagerwanne 1 werden dabei vorzugsweise von einem einzigen Blechabschnit gebildet, der an seinen Querkanten mit rechtwinkligen Abkantungen 8 versehen ist, die jeweils dort, wo die Biegekanten zwischen Stirnwand 5 und Boden 6 sowie Rückwand 7 und Boden 6 liegen, zwickelartige Ausklinkungen haben, durch welche zwischen den Abkantungen 8 Gehrungsstöße 9 entstehen. Die beiden Querwände 10 und 11 der Lagerwanne 1 werden aus besonderen Blechzuschnitten geformt, welche sich innenseitig an die Abkantungen 8 anlegen und mit diesen durch Punktschweißungen 12 fest verbunden werden können.In Fig. 1 a stackable storage trough 1 is shown, which can have a relatively large width 2, a relatively large depth 3 and a relatively low overall height 4. The end wall 5, the bottom 6 and the rear wall 7 of the bearing trough 1 are preferably formed from a single sheet metal section which is provided at its transverse edges with right-angled bevels 8, each where the bending edges between the end wall 5 and the bottom 6 and the rear wall 7 and bottom 6, have gusset-like notches through which 8 miter joints 9 are formed between the folds. The two transverse walls 10 and 11 of the bearing trough 1 are formed from special sheet metal blanks which lie on the inside on the bevels 8 and can be firmly connected to them by spot welds 12.

Die aufrechten Ränder der beiden Querwände 10 und 11 werden jeweils, wie insbesondere aus Fig. 8 ersichtlich ist, durch einen gedoppelten Blechabschnitt 13 gebildet, welcher auf halber Breite der Blechdoppelung mit einer parallel zur Stirnwand 5 bzw. zur Rückwand 7 gerichteten Abkantung 14 versehen ist. Nicht nur die Schweißpunkte 12 zwischen den Abkantungen 8 sowie den Querwänden 10 und 11, sondern auch weitere Schweißpunkte 15 der Stirnwand 5 mit den Abkantungen 14 und der Rückwand 7 mit den Abkantungen 14 gehen dabei jeweils durch die Blechdoppelung 13 hindurch. Eine besonders hohe Formstabilität an den aufrechten Wannenecken wird hierdurch gewährleistet. Erwähnenswert ist hierbei noch, daß auch dann, wenn sich die Wannenstirnwand 5 nur etwa über die halbe Bauhöhe 4 der Lagerwanne 1 erstreckt, die Abkantungen 14 im Bereich der Blechdoppelungen 13 dort die gleiche Höhe haben, wie im Bereich der Rückwand 7, um eine optimale Stabilität gegen seitliches Ausbrechen der Querwände 10 und 11 zu erreichen.The upright edges of the two transverse walls 10 and 11 are each formed, as can be seen in particular from FIG. 8, by a double sheet metal section 13, which is provided halfway across the sheet metal double with a bevel 14 directed parallel to the end wall 5 and the rear wall 7 . Not only the weld points 12 between the folds 8 and the transverse walls 10 and 11, but also further weld points 15 of the end wall 5 with the folds 14 and the rear wall 7 with the folds 14 each pass through the sheet metal double 13. This ensures particularly high dimensional stability at the upright tub corners. It is also worth mentioning that even if the tub end wall 5 extends only about half the height 4 of the storage tub 1, the bevels 14 in the area of the sheet metal doubles 13 have the same height as in the area of the rear wall 7 in order to achieve an optimum To achieve stability against lateral breaking of the transverse walls 10 and 11.

Mindestens die beiden Querwände 10 und 11 der Lagerwanne 1 sind mit einem eine waagerechte Stapelfläche 17 und eine senkrechte Begrenzungsfläche 18 aufweisenden Stapelrand 16 versehen, wie er deutlich aus Fig. 2 erkennbar ist. Dabei wird die waagerechte Stapelfläche 17 vom oberen Wandabschnitt einer in die Querwand 10 bzw. 11 eingeformten Sicke 19 gebildet, während es sich bei der senkrechten Begrenzungsfläche 18 um eine nach oben an diese Sicke 19 einstuckig anschließende Abkantung handelt.At least the two transverse walls 10 and 11 of the storage trough 1 are provided with a stacking edge 16 having a horizontal stacking surface 17 and a vertical boundary surface 18, as can be clearly seen from FIG. 2. The horizontal stacking surface 17 is formed by the upper wall section of a bead 19 molded into the transverse wall 10 or 11, while the vertical boundary surface 18 is a bevel which adjoins this bead 19 in one piece.

Nach außen wird der Stapelrand 16 durch ein Hohlprofil 20 abgeschirmt und stabilisiert. Dieses Hohlprofil 20 wird dabei von einem zu dem die senkrechte Begrenzungsfläche 18 des Stapelrandes bildenden Abkantungsteil parallelen Wandabschnitt (21), einem schräg zur Querwand 10 bzw. 11 verlaufenden Wandabschnitt 22 und einem zur Querwand 10 bzw. 11 parallelen Stützabschnitt 23 gebildet. Der Wandabschnitt 21 des Hohlprofils 20 schließt sich dabei so über einen Bogenabschnitt 24 einstückig an den die Begrenzungsfläche 18 bildenden Abkantungsteil an, daß zwischen ihm und der Begrenzungsfläche 18 ein Spaltabstand 25 gebildet ist, der etwa der Blechdicke entspricht. Der Wandabschnitt 21 hat dabei eine solche Breite, daß er sich etwa bis zur Höhe der Unterkante der Sicke 19 erstreckt, wo er in den schräg zur Querwand 10 bzw. 11 hin verlaufenden Wandabschnitt 22 übergeht. Durch Schweißpunkte 26 ist der Stützabschnitt 23 des Hohlprofils 20 fest mit der Querwand 10 bzw. 11 verbunden.The stack edge 16 is shielded and stabilized from the outside by a hollow profile 20. This hollow profile 20 is formed by a wall section (21) which is parallel to the bent part forming the vertical boundary surface 18 of the stacking edge, a wall section 22 which runs obliquely to the transverse wall 10 or 11, and a support section 23 which is parallel to the transverse wall 10 or 11. The wall section 21 of the hollow profile 20 adjoins the bend part forming the boundary surface 18 in one piece via an arc section 24 in such a way that a gap distance 25 is formed between it and the boundary surface 18, which corresponds approximately to the sheet thickness. The wall section 21 has such a width that it extends approximately to the height of the lower edge of the bead 19, where it merges into the wall section 22 which extends obliquely to the transverse wall 10 or 11. The support section 23 of the hollow profile 20 is firmly connected to the transverse wall 10 or 11 by welding points 26.

Durch die besondere Ausgestaltung des Hohlprofils 20 bietet dieses nicht nur dem Stapelrand 16 an den Querwänden 10 und 11 einen guten Schutz gegen Verbeulen und Einknicken durch äußere Krafteinwirkungen, sondern es stellt gleichzeitig sicher daß diese Stabilitätserhöhung mit einer minimalen Ausladung des oberen Wannenumfangs gegenüber der Umrißform des Wannenbodens erreicht wird.Due to the special design of the hollow profile 20, this not only offers the stacking edge 16 on the transverse walls 10 and 11 good protection against buckling and buckling due to external forces, but it also ensures that this increase in stability with a minimal projection of the upper tub circumference compared to the outline shape of the Tub bottom is reached.

Eine weitere Stabilitätserhöhung des Hohlprofils 20 kann im Bedarfsfalle dadurch erreicht werden, daß in den zu der senkrechten Begrenzungsfläche 18 des Stapelrandes 16 parallelen Wandabschnitt 21, und zwar etwa auf Höhe der einwärts gerichteten Sicke 19 eine auswärts gerichtete Sicke 27 eingeprägt wird, deren Tiefe etwa gleich der Blechdicke ist. Die seitliche Ausladung des Hohlprofils 20 wird durch die Sicke 27 also nur minimal vergrößert.If necessary, a further increase in the stability of the hollow profile 20 can be achieved by embossing an outward-facing bead 27 into the wall section 21 parallel to the vertical boundary surface 18 of the stacking edge 16, approximately at the level of the inward-facing bead 19, the depth of which is approximately equal the sheet thickness is. The lateral projection of the hollow profile 20 is therefore only minimally increased by the bead 27.

Die Oberkante der Rückwand 7 ist zur Versteifung mit einem nach auswärts eingerollten Rand 28 versehen, wie das besonders deutlich den Fig. 3 und 6 entnommen werden kann. Aus Fig. 4 ist dabei ersichtlich, daß zur Herstellung dieses eingerollten Randes 28 die Oberkante der Rückwand 7 zunächst mit einer Blechdoppelung 29 versehen wird. Diese Blechdoppelung 29 wird dann entsprechend der Fig. 5 zunächst spitzwinklig abgekantet sowie schließlich in die aus Fig. 3 ersichtliche Form gerollt. Dabei ist offensichtlich, daß durch diese Maßnahme der an der Rückwand 7 gebildete Versteifungsrand 28 eine hohe Formstabilität erhält. Wichtig ist dabei auch, daß die Rückwand 7 in Höhe der Stapelfläche 17 des Stapelrandes 16 der Querwände 10 und 11 mit einer wenigstens um Blechdicke nach auswärts gerichteten Verpressung 30 versehen wird, wie das aus den Fig. 3 und 6 ersichtlich ist, um hierdurch das gleichgerichtete Übereinanderstapeln mehrerer Lagerwannen 1 in der aus Fig. 7 ersichtlichen Art und Weise möglich zu machen. Der dem Versteifungsrand 28 vorgelagerte Bandabschnitt 31 oberhalb der Verpressung hat die gleiche Aufgabe, wie die Begrenzungsflächen 18 des Stapelrandes 16, d. h. er dient zur Ausrichtung beim Übereinanderstapeln mehrerer Lagerwannen 1 gemäß Fig. 7.The upper edge of the rear wall 7 is provided with an outwardly rolled edge 28 for reinforcement, as can be seen particularly clearly in FIGS. 3 and 6. From Fig. 4 it can be seen that to produce this rolled edge 28, the upper edge of the rear wall 7 is first provided with a sheet metal double 29. This sheet metal doubling 29 is then first folded at an acute angle, as shown in FIG. 5, and then rolled into the shape shown in FIG. 3. It is obvious that this measure gives the stiffening edge 28 formed on the rear wall 7 high dimensional stability. It is also important that the rear wall 7 at the level of the stacking surface 17 of the stacking edge 16 of the transverse walls 10 and 11 of a compression 30 directed outwards at least by the sheet thickness, as can be seen from FIGS. 3 and 6, in order thereby to make it possible to stack a plurality of storage trays 1 in the same manner in the manner shown in FIG. 7. The band section 31 upstream of the stiffening edge 28 above the pressing has the same function as the boundary surfaces 18 of the stacking edge 16, ie it serves for alignment when stacking a plurality of storage trays 1 according to FIG. 7.

Damit eine stabile Verbindung zwischen dem Stapelrand 16 der Querwände 10 und 11 und dem Versteifungsrand 28 der Rückwand 7 erreicht wird, ist der dem Versteifungsrand 28 vorgelagerte Wandabschnitt 31 jeweils an seinen Enden mit einer abgewinkelten Zunge 32 ausgestattet (Fig. 3 und 6). Die abgewinkelten Zungen 32 greifen dabei in den Abstandsspalt 25 zwischen der senkrechten Begrenzungsfläche 18 des Stapelrandes 16 und dem dazu parallelen Wandungsteil 21 des Hohlprofils 20 ein und sind mit diesen durch Punktschweißung fest verbunden.So that a stable connection between the stacking edge 16 of the transverse walls 10 and 11 and the stiffening edge 28 of the rear wall 7 is achieved, the wall section 31 upstream of the stiffening edge 28 is equipped at its ends with an angled tongue 32 (FIGS. 3 and 6). The angled tongues 32 engage in the spacing gap 25 between the vertical boundary surface 18 of the stack edge 16 and the wall part 21 of the hollow profile 20 which is parallel thereto and are firmly connected to them by spot welding.

Erwähnt sei noch, daß auch die Stirnwand 5 mit einem nach außen eingerollten Versteifungsrand 34 versehen werden kann. Dieser läßt sich dabei im Bedarfsfalle in ähnlicher Weise durch Blechdoppelung stabilisieren, wie dies in den Fig. 3 bis 5 für den Versteifungsrand 28 der Rückwand 7 gezeigt ist.It should also be mentioned that the end wall 5 can also be provided with a stiffening edge 34 rolled outwards. If necessary, this can be stabilized in a similar manner by sheet metal doubling, as is shown in FIGS. 3 to 5 for the stiffening edge 28 of the rear wall 7.

Da die Stinrwand 5 beim gezeigten Ausführungsbeispiel einer Lagerwanne 1 etwa nur halb so hoch wie die Rückwand 7 und die beiden Querwände 10 und 11 ausgeführt ist, weist an dieser Stelle die Lagerwanne 1 auch dann eine Sicht- bzw. Eingriffsöffnung auf, wenn mehrere Lagerwannen 1 in der aus Figur 7 ersichtlichen Art und Weise übereinandergestapelt werden.Since the front wall 5 in the exemplary embodiment of a storage trough 1 shown is only about half the height of the rear wall 7 and the two transverse walls 10 and 11, the storage trough 1 also has a viewing or engaging opening at this point when a plurality of storage troughs 1 are stacked on top of one another in the manner shown in FIG.

Selbstverständlich ist es auch möglich, die vorstehend in Verbindung mit einer Lagerwanne beschriebenen Merkmale auf Lagerkästen anzuwenden.Of course, it is also possible to apply the features described above in connection with a storage trough to storage boxes.

Insbesondere bei Lagerkästen, aber auch bei Lagerwannen kann es zweckmäßig sein, die obere Kante einer weiteren Wand oder gar die oberen Kanten aller Wände mit den beschriebenen Stapelrändern auszurüsten. In den Eckbereichen, in denen zwei Stapelränder rechtwinklig zusammenlaufen, muß dann für eine entsprechende Verbindung, bspw. durch Einstecken relativ breiter Zungen, gesorgt werden.In the case of storage boxes in particular, but also in the case of storage trays, it can be expedient to equip the upper edge of a further wall or even the upper edges of all walls with the stacking edges described. In the corner areas in which two stack edges converge at right angles, a corresponding connection must then be provided, for example by inserting relatively wide tongues.

Abschließend soll nur noch erwähnt werden daß es möglich ist, wenigstens an der Stirnwand 5 und der Rückwand 7 der Lagerwanne 1 Zungenpaare 35 auszustanzen und winkelförmig nach innen zu formen, damit durch diese Halteführungen für lösbar einzusetzende Trenn- bzw. Zwischenwände gebildet werden.In conclusion, it should only be mentioned that it is possible to punch out tongue pairs 35 at least on the end wall 5 and the rear wall 7 of the bearing trough 1 and to form them in an angular shape so that these holding guides form separable partitions or partitions.
