Description

background the invention

The present invention relates to a collapsible transport container according to the preamble of claim 1. Such a transport container is from the DE 100 47 616 A1 known.

The invention particularly relates to a reusable, collapsible transport container, such as these. B. for the transport of parts in closely juxtaposed, unmixed pack using suitable internal structures in the transport container in the automotive industry for overseas assembly plants use. The need for garniturenweiser return shipment of all parts of the transport container after the discharge itself, as well as the respective required internal structures, clips etc. in the form of a reduced return volume bill, various designs have been developed, among others DE 199 08 824 C2 as well as the generic DE 100 47 616 A1 , etc. in which the front and side walls by means of fixed hinges and z. T. from / hinged hinges are connected to the substructure. All these constructions have the practical disadvantage that they are extremely susceptible to repair and must undergo a complete time-consuming and costly overhaul after just a few orbits. The reason for this is given by the fact that all of these hinges, which are connected by screw or rivet joints with the front and side walls of the container, bent or torn due to the leverage effects when not absolutely appropriate handling and thus severely limited in their function, or completely unusable. In addition, the hinges are often damaged during shipping, even if they are aushängbar, and bent in the rough operation, if they are not aushängbar, the risk is even greater, especially in larger-scale container parts undue forces on the hinges due to the Significant leverage when building and dismantling the transport container arise.

The Practice in the use of the above-mentioned structures with hinges proves the very high, ongoing compared to the purchase price Effort for Repairs, whereby by the respective connection of mostly two Parts / walls the short-term replacement cost is correspondingly greater than the replacement from a single, damaged, independent Part. Furthermore suffers the rigidity of the container walls due to buckling tendency by dividing the walls in exclusively horizontal direction and joint through hinges. This makes in particular disadvantageous for the life of such transport container in multiple stacking noticeable in the stores, with the pressure on the bottom container depending on load weights can be very high.

One Another disadvantage of such folding structures is usually the less tightness of the transport container at the edges / corners and joints on the hinges due to missing Überstandsfälze to avoid entry of moisture, impurities, dust on the z. T. oiled sheet metal parts while the transport route, which is not always exclusively on the envelope inside a sealed ISO steel container limited.

Of the Advantage to connect with only by loose clips with each other Items, d. H. Floor / walls / lid a transport container is due to the hinge connection of several parts together Disadvantage and leads to increased Effort for repairs.

Of the Invention has for its object to propose a transport container, which the advantages of the clip / bracket system with loose items and thereby cheaper, fast interchangeability of all items in case of damage while the transport chain for reusable containers z. For example the transport of automotive parts to the overseas assembly plants with the advantages of a garniturenweise return of all to the respective container belonging, required parts and fixtures for safe positioning the contents, surplus clips etc. united in a much lower return volume and the latter itself an independent, compact, transport-safe, high stackable unit forms.

These Task is solved according to the claim.

In the dependent claims are features of preferred embodiments characterized.

The dismountable, reusable transport container ( 10 ), has a floor, in particular from a floor pallet ( 11 ), in a suitable for forklift and pallet truck undercarriage construction, as well as four lower inner walls, namely two lower forehead ( 12 . 13 ) and two lower side walls ( 14 . 15 ), which are mounted around the actual outer wall thickness offset inwards on the floor ( 2 ). At least one of these lower inner walls ( 15a ), preferably on the longer side wall side, is to be removed by a sliding arrangement to the outside, whereby facilitated during loading and unloading of the container easier, unhindered access to the inside. At these lower inner walls are each spacers ( 16 ), the thickness of the outer walls ( 17 . 18 . 19 . 20 ) and by analogous recesses of the outer walls ( 17a . 18a . 19a . 20a ). While the completely constructed transport container in full height, d. h with attachment of the outer, high side walls ( 17 . 18 . 19 . 20 ) with the help of suitable mounting parts for the secure recording of z. B. sheet metal stamping for the automotive industry can serve inside, this construction allows the return of the emptied transport container in a much lower overall height on the basis of the lower, inner side walls ( 12 . 13 . 14 . 15 ), on which the lid ( 21 ) comes to rest. While the end walls ( 17 . 18 ) can be accommodated inside the return shipping container, as well as the previously described fixtures for receiving the contents (for example, metal stampings), the longer side walls are superposed in corresponding recesses ( 27 ) on the two low end walls ( 12 . 13 ) placed so that they come to rest flush with the spacers attached to this point outwards. The overlying lid ( 21 ) with the clips in the places where the spacers ( 16 ) underneath are clipped, so that forms a transportable compact return shipping unit with much lower height than the actual transport container in fully assembled state. Next to the end walls ( 17 . 18 ) inside the return shipping unit in addition to the fixtures for receiving the contents and all surplus spring steel clips, which do not come into function when returning in the low unit, stored safely and without loss, stowed.

Furthermore - in contrast to the construction acc. DE 100 47 616 A1 - basically always uses a single type of clips, which eliminates the risk of confusion and associated delays.

In the first embodiment of the invention described below, as shown in FIG 1 and 2 recognizes the bottom of a bottom plate ( 22 ) with underlying spacer blocks ( 23 ) and skid boards ( 24 ) as slip rails, three fixedly mounted on this bottom plate low end and side walls ( 12 . 13 . 14 ), as well as an extendable low sliding wall ( 15 ), which facilitates removal after loading by loading the packers.

4 shows that at each of the low inner walls, which are mounted around the outer wall thickness inwardly, two spacers ( 16 ) are mounted by outer wall thickness, which in their positioning with the slots of the overlying lid ( 21 ) correspond in such a way that in the packaged state at the low Return shipping unit usually eight clips connect the lid to the rest of the unit down by placing the spacers ( 16 ) and ensure that no loose parts can fall out of the interior of the smaller packing unit.

As 3 shows, the shorter end walls ( 17 . 18 ) are kept longitudinally inside the low packing unit; the long side walls ( 19 . 20 ) are placed in corresponding recesses ( 27 ) of the low end walls ( 12 . 13 ) are inserted one above the other parallel to the longitudinal direction of the container, so that they face the spacers ( 16 ) come to lie flush to the outside. The recess depth corresponds to the total thickness of the two superimposed side wall panels ( 19 . 20 ), the width of the recesses ( 27 ) at both low end walls ( 12 . 13 ) corresponds in each case to the height of the high side wall parts ( 19 . 20 ). It can naturally only be as large as the width of the low end walls ( 12 . 13 ). The bottom plate ( 22 ) receives circumferential folds on all four sides, in which the high end and side walls ( 17 . 18 . 19 . 20 ), laterally they are also due to the low walls ( 12 . 13 . 14 . 15 ) supported and limited. Inside the low return unit, the extra clips and the fixtures for the recording positioning of the contents are stowed loss-secure.

3a shows an exploded view, disassembled view, wherein the end parts all internal construction parts in disassembled form and the remaining clips are inserted in the low return volume. After inserting the two side wall parts in the recesses of the low inner end walls in outwardly flush shape to the spacers, is compactly sealed with the lid.

4 shows the finished packed return unit with the lid on and down over the spacers clipped cover as a conclusion upwards. In general, eight clips, ie at each corner two pieces, the rest are together with the other walls and internals inside the Rückversandvolumens, gem. 3a ,

After completion of the pack, ie eg loading of the bottom pallet ( 11 ) with the help of the recordings ( 30 ) for the content (see 1a ), in the case of execution z. B. Fender sheet metal parts ( 31 ), the high outer end walls ( 17 . 18 ) as well as outer side walls ( 19 . 20 ), wherein in each case the spacers ( 16 ) represent a valuable positioning aid by passing through the analog recesses ( 17a . 18a . 19a . 20a ) immerse. In such a way exactly attached, the high walls remain connected by already a single clip, stand alone and can from a single person in turn through the remaining clips, both with the ground; as well as interconnected at the container corners ( 1 ). After placing the lid, the high unit packed with contents is firmly closed with the help of the remaining clips and is ready for dispatch. Stacking fuses, such. B. stackable bowls ( 25 ) are mounted on all four corners of the lid, facilitate stacking and prevent slippage during transport of any sequence of high, full or low return pack units with the same bottom or lid sizes.

A second embodiment describes a transport container in the sense of the aforementioned criteria, but with a front and side wall height which is greater than the inner width of the low return container, or the width of the low end parts ( 12 . 13 ).

5 shows a collapsible, built-up transport container in a completely closed state according to a second embodiment, in which due to the opposite container width to large container height, the Behälterstirn- and side walls are divided in half for the purpose of the best possible stability and carrying capacity when stacking in the horizontal direction in the long Sidewalls and in the vertical direction at the end walls. One can see here the spacers of the same material thickness reaching through the front or side walls in the lower area as in the outer walls. The because of the four-fold thickness of the four side wall halves more downwardly displaced spacers in the end wall area are provided with slots in the interior for the purpose of using uniform clips leg lengths of all reaching for use clips, the spacers on the side wall side correspond exactly to the nature of the embodiment 1 , The total number of clips required depends on the dimensions of the transport container in the 3 axial directions.

According to the invention, the outer walls are divided, namely the side walls ( 19 . 20 ) in the horizontal direction and the end walls ( 17 . 18 ) in the vertical direction. This is in contrast to the construction mentioned in the introduction ( DE 100 47 616 A1 ) ensures that for the purpose of stability improvement and thus life increase at the four edges of the container kink-load resistant, continuous walls are present, which give the same in the corner areas also high security against Ausknickgefahr due to Verklammerung with horizontally divided side walls. Sliding wedge connecting straps ( 26 ) (Detail A in 6 ), which are attached to the joints of the front and side walls, serve for the Rückversandpro zess to separate the wall halves of each other.

Before creating the full, loaded transport container height they are dimensionally stable and joint-tight connected by lateral telescoping friction due to wedging action ( 6 ). With the above-mentioned method, it is possible to design a transport container for the full container height even when only half the ISO container width is used. In contrast, a transport container with full ISO container width can accommodate end and side walls in undivided form for the full ISO container height.

In the low return container, as in 7 to 9 shown, the four pieces of split end walls in pairs rotated 180 degrees against each other and stored offset to the return of the sliding wedge connecting straps, the four pieces of split sidewalls are equally rotated 2 pieces 180 degrees against each other, offset by the Schiebekeilverbindungslaschenbreite and a total package of four plates on the with recesses ( 27 ), low, inner end walls ( 12 . 13 ) stored. In this case, the sliding wedge connecting straps ( 26 ), which are attached to the uppermost side wall half, down, so that the cover plate ( 21 ) over the entire surface, just lying on the total package of the side walls comes.

8th shows the two second Stirnteilhälften placed on it and the first two long side wall halves also rotated against each other and placed one another in the recesses of the low inner end walls, positioned outwardly flush with the spacers, inserted. Subsequently, in the same way, the second two long side wall halves twisted against each other must be placed here on it. The sliding wedge connecting straps are always inwardly facing each other in such pairwise assembly, so that they do not deposit in the total thickness, but only result in a slight lateral offset of the plates.

The depth of the recesses ( 27 ) at the low inner end walls ( 12 . 13 ) is now four times the plate thickness, the width of which is wider than the width of the side wall halves by the return width of the sliding wedge connecting straps. Taking into account the recess depths in quadruple plate thickness in this embodiment, the spacers ( 28 ) (Detail C in 6 ), which are flush with the side wall halves outwardly to the outside, provided with slots for clipping the low packing unit with the lid. At the low, inner side walls remain the spacers ( 16 ) exist in unchanged form with the engagement of the clips from below to the spacers during clipping ( 10 ). Also this low packing unit for the special case of transport containers, which i. P. are higher than wide and thus make a division of the side and end walls required forms an outwardly closed unit, which usually by 8 clips, as the embodiment shows, can be safely closed and inside all parts for the Completion of the assembled container including all the necessary clips and fixtures to hold the contents to be packaged ( 10 ). Fully closed transport container after DE 100 47 616 A1 and DE 199 08 824 C2 are only partially feasible with a much greater height than width. This fact may, depending on the size and shape of the contents in practice often lead to unfavorable packaging arrangements thereof or to a less favorable volume utilization.
