Definitions

  • the invention relates t a storage tub or a bearing box made from sheet metal which and which in particular has an S ichtöff- voltage, with a formed by a bead and integrally formed on this subsequent bends stacking edge, the horizontal a substantially, by the upper bead wall Has a stacking surface and an approximately vertical boundary surface consisting of the bend for receiving a further storage trough or another storage box, an outside profile being formed on the outside of the part of the stacking edge forming the vertical boundary surface, which supports stiffening against the box wall.
  • Stackable troughs or storage boxes of this type already belong to the prior art due to DE-Gm 19 97 260 and DE-OS 17 86 082. They have the advantage that the actual stacking 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.
  • a disadvantage of the generic stackable storage boxes of the known type is that the hollow profiles shielding the actual stacking edge from the outside have a relatively large projection, so that the storage space required for adjusting the individual storage boxes on all sides dimensioned considerably larger no must than the box base bounded by the box bottom. This inevitably results in relatively large, unusable cavities between two storage boxes or known construction set up next to one another.
  • the invention aims to overcome these disadvantages. It is therefore based on the task of finding a spatial shape for a storage trough or a storage box of the generic type made of BLech, which despite adequate securing of the stack edge against buckling and buckling and while maintaining a high overall stability to reduce the largest outer tub or box dimensions leads relative to their floor area.
  • the hollow profile has a wall section parallel to the bend part forming this vertical boundary surface of the stacking edge, which I extend approximately to the height of the lower edge of the bead and there in a wall running obliquely to the edge wall section merges with which a support section parallel to the box wall adjoins, which is firmly connected to the box wall, for example by " spot welding " .
  • Substantially part of the hollow profile which stabilizes the walls lies approximately at the same height as the bead located below the stacking edge and can thus be delimited to the outside by relatively wide, flat surfaces.
  • the innovation feature specified in the second claim can also prove to be advantageous.
  • a further stabilization measure to protect the stack edge against undesirable effects of force effects can also be achieved after the innovation by the feature specified in the third claim.
  • a stackable storage trough 1 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 storage trough 1 are preferably made from a single sheet metal section formed, which is provided at its transverse edges with right-angled bevels 8, which have where the bending edges between the front wall 5 and bottom 6 and the rear wall 7 and bottom 6, gusset-like notches, through which 8 miter joints 9 are formed between the bevels.
  • 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.
  • 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 .
  • 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 .
  • the welding points 12 between the bevels 8 and the transverse walls 10 and 11 but also further welding points 15 of the end wall 5 with the bevels 14 and the rear wall 7 with the bevels 14 each pass through the sheet metal double 13. This ensures particularly high dimensional stability at the upright tub corners.
  • At least the two transverse walls 10 and 11 of the storage trough 1 are provided with a stacking edge 1b 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 one after at the top of this bead 19 is an integral subsequent bend.
  • This hollow profile 20 is formed by a wall section parallel to the bent part forming the vertical boundary surface 18 of the stacking edge, a wall section 22 extending obliquely to the transverse wall 10 or 11 and a support section 23 parallel to the transverse wall 10 or 11.
  • the wall section 21 of the hollow profile 20 thus integrally encloses itself via a curved section 24 on the bent part forming the boundary surface 18 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 extending obliquely to the transverse wall 10 1 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.
  • this not only offers the stacking edge 16 on the transverse walls 10 and 11 good protection against denting and buckling due to external forces, but at the same time ensures that this increase in stability with a minimal projection of the upper tub circumference compared to the outline shape of the tub floor is reached.
  • a further increase in the stability of the hollow profile 20 can be achieved, if necessary, by embossing an outward bead 27 into the wall section 21 parallel to the vertical boundary surface 17 of the stacking edge 16, approximately at the level of the inward 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.
  • the upper edge of the rear wall is provided with an outwardly rolled edge 28 for stiffening, 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 double elun g 29 is then a b - edged at an acute angle according to FIG. 5 and finally 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.
  • the rear wall 7 is provided at the level of the stacking surface 17 of the stacking edge 16 of the transverse walls 10 and 11 with a pressing 30 directed outwards at least by the sheet thickness, as can be seen from FIGS. 3 and 6, in order to thereby to make rectified stacking of several storage trays 1 in the manner shown in FIG. 7 possible.
  • 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 is used for alignment when stacking several storage trays 1 according to FIG. 7.
  • the wall section 31 upstream of the stiffening edge 28 is equipped at both 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 stacking edge 16 and the wall part 21 of the hollow profile 20 parallel thereto and are firmly connected to them by spot welding 33.
  • 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 is shown.
  • the Stinrwand 5 in the illustrated embodiment of a storage trough 1 is only about half high as the rear wall 7 and the two transverse walls 1o and 11, the storage trough 1 also has a viewing or engaging opening at this point when several storage troughs 1 can be stacked on top of one another in the manner shown in the figure.
