Abstract

1. A stackable pallet-crate formed of four upright posts (1) rigidly interconnected by a floor member (2), each post (1) carrying sliding channels (5, 6) into which are inserted removable lateral panels (7, 12) ; the internal faces (6) and the external faces (5) of the sliding channels being of uneven heights, the external face (5) extending over at least the full usable height of the crate, this height being equal to an integer multiple of the width of the pannel (7, 12) to which is added a substantial fraction (x) of this width, characterized in that the height of the internal face (6) equals the integer multiple being immediately smaller than said height to which is added a fraction (y) of said height being approximately equal to or smaller than the previous fraction, so that the difference of heights (x + z) between the internal face (6) and the external face (5) will be approximately equal to or larger than one panel width (7, 12).

Description

t-J- 2555969 The pallet box traditionally used for the

  handling and storage is usually

  a fixed height box with at least one opening side

  ble totally or partially. Such a box (French patent 1 508 153) can in particular be used for the storage and handling of small parts, but it has the disadvantage that, when the boxes are stacked, it is impossible or very difficult to pick up parts, this socket coins also becoming very awkward as the boxes empty. In addition, such cases are

  bulky when empty.

  The subject of the invention is a stackable pallet box devoid of these drawbacks, that is to say from which the parts can be removed easily and safely whatever its level of filling, this removal being also possible when the

  boxes are stacked. In addition, the fund according to the invention

  tion is variable volume and can be, when empty,

stored in a low volume.

  The box according to the invention is formed by four uprights rigidly connected by a lower plate, each upright carrying slides in which insert removable side panels, and it is characterized in that the internal and external faces of the slides are of height uneven, the external face extending at least over the whole useful height of the body which is equal to a multiple

  whole width of the panel plus a frac-

  substantial width of this width, while the height of the internal face is equal to the immediately lower whole multiple of said width plus a fraction of this width less than the previous fraction, so that the difference in heights between internal face and face external or

  greater than a panel width.

  By useful height of the box is meant the height between the lower plate and the top of the uprights, reduced by the height of overlap of the stacking feet when these

recover amounts.

  With a box thus constituted, the pan-

  side buckles are constantly removable, even when the box is part of a stack, and yet the; panels cannot accidentally spill out; we can therefore remove the panels as and when the box is emptied, as we can put in place as and when it is filled, even after stacking, which greatly facilitates

  handling and ensures the versatility of the boxes.

  The invention also relates to the following arrangements: a) The lower plate is formed by four lateral crosspieces, the median zones of which are connected together by spacers parallel to the diagonals, the assembly supporting a bottom surface. b) Provisions for uprights having the same construction as the uprights are provided, the useful height being, in this case, the height of the enhancement possibly reduced by the height of

overlap of the stacking feet.

  c) The stacking feet consist of cups with a concavity facing downwards which cover the tops of the mounts and risers,

  preferably beveled themselves.

  d) The uprights and extensions are formed of tubes made up of assembled angles, the wings of the external angle protruding from the tube and

  forming the outer faces of the slides.

  e) The risers are fitted with feet

  rant in the uprights and riser tubes.

  The invention is more fully described below.

  after with reference to the attached drawing in which: 5. Figure 1 is an overall perspective view of an exemplary embodiment of the stackable pallet box according to the invention; Figure 2 is a sectional view of an upright; 10. Figure 3 is a top view; Figure 4 is a side view of an upright; Figure 5 is a side view of an extension; 15. Figure 6 illustrates, in perspective, a box with extensions; Figure 7 illustrates, in perspective, the stacking of two boxes; Figure 8 illustrates in plan the stacking

empty.

  Referring to these figures, it can be seen that a pallet box according to the invention is formed by four uprights 1 rigidly connected to a floor or

  lower tray 2 rectangle or square. In the example

  ple shown (Figure 3), the plate 2 is formed of side tubes 3 and diagonal spacers 4 connecting the midpoints of the tubes 3, the assembly supporting a

  bottom surface 2, for example of sheet metal. This arrangement

  tion has the advantage of facilitating handling by pallet trucks whose arms are supported on

the tubes 3 and the spacers 4.

  The uprights 1 carry slides 5, 6 into which are inserted side panels

removable 7 or 12.

  According to the invention, the internal6 and external5 faces of the slides are of unequal heights: the faces 5 extend at least from the level of the plate 2 to the upper level of the uprights 1, possibly reduced by the depth of the cups 8 forming seat and stacking feet; this distance, called the useful height in the pre-

  sense description, is equal to an integer multiple n

  the width of a panel 7 or 12, plus a frac-

  tion x of this width; the internal faces 6, on the other hand, extend from the plate 2 over a height equal to the immediately lower multiple (nl) of the width of the panel plus a fraction y less than the fraction x, so that the difference in height sides 5 and 6 (x + z) is slightly greater than a panel width (fig. 4 and 5)

  As shown in Figure 7, this arrangement

  tion allows to place and remove panels 7 or 12 even

  when the pallet boxes are stacked.

  This results in several advantages: During loading, the panels 7 can be placed as they are filled, which allows better storage, better filling, with

  less breakage or deterioration.

  When loading, the upper part of the body is always accessible through the space between upper panels 7 or 12 and lower plate 2 of the

stacked body.

  As unloading, panels 7 or 12 can be removed one by one, which ensures complete and easy accessibility of the parts up to

complete emptying of the box.

  In any case, there can be no accidental spillage of parts because the panels

  7 or 12 can only be removed by a maneuver.

  tilting glass towards the inside of the body.

  The invention provides extensions 10 (Figure 5 and Figure6) which increase the

  volume of boxes. The extensions 10 have the same cons-

  titution that the uprights 1 in particular with regard to the slides 5 and 6 and their respective heights, the distance (x + z) also being greater in width of the panel. The box with a level of extensions is shown in Figure 6; we see that panels 7 or 12, at

  the junction with the extensions 10, are contiguous.

  In the case of extensions 10, the useful height is the height of the extension possibly reduced by

the depth of a cup 8.

  As shown in FIG. 2, the uprights are preferably tubular and of rectangular or square section and the extensions 10 are extended by feet 11 dimensioned to be housed in the upper part of the

amounts 1, or extensions 10.

  According to a preferred embodiment, the uprights 1 and risers 10 are produced by welding external angles la and internal lb, the wings of the angles la projecting so as to form the external face 5 of the slides. The internal faces 6 are added by welding, this profile being able to just as well

  be made in one piece by extrusion or profiling.

  Panels 7 can be solid or perforated

  as shown in 12 figure 7, for reasons of simplicity

  management or visibility of the contents of the boxes.

  FIG. 8 shows that the boxes, according to the invention, can be stacked empty without great bulk by angular shift from one box to the next.
