The transport unit 1 shown in Figure 1 consists of a house appliance 2 to be packaged and shown in dotted lines, e.g. B. a household refrigerator and transport packaging, with two such transport units on top of each other are stacked (in Fig. 1 are for the sake of clarity the two transport units at a short distance above one another drawn). As usual, the household appliance has a Rigid outer housing, an appliance door 3 and on the back an evaporator 4 of a not shown Refrigeration units. The domestic appliance 2 rests on one Bottom part 5 of the stackable transport packaging, which preferably of a suitable plastic, e.g. Polypropylene, is made. This bottom part 5 - as well as the cover part 6 described - is as a shell part made of dimensionally stable Material formed and has one in this Embodiment the basic shape of the household appliance 2 or whose outer shell shell shell 7 in Form of a shelf and a protruding vertically, circumferential shell edge flange 8. Like the figures 1 and 3 show, the bottom is largely closed and thus the edge contour of the shell edge flange that is capable of roller conveyors 8 on two opposite flange parts of the rectangular bottom part 5 two incisions 9, which run out freely with centering slopes 10. These cuts 9 are used to insert the tensioning straps described 11. There is a between the incisions 9 Entry opening 12 for lifting transport vehicles, e.g. Lifting forks from Forklifts. Located to the side of the incisions 9 in the aforementioned flange parts of the shell edge flange 8 handle openings 13 for manual lifting of the transport unit. The identical cover part in the exemplary embodiment 6 is directional with the bottom part 5 on the Put on the top of the household appliance 2, so that the rotating Shell edge flange 8 a part of the top of the household appliance 2 embraces. Here triangular-shaped pairs are used Centering approaches 14 on the one hand the limitation of a Incision 15 for the aforementioned straps 11 and on the other hand, they fit together with those that belong together in pairs Centering bevels 10 of the bottom part 5 of the the above-described transport unit 1 stacked another Transport unit, as can be clearly seen from Fig. 1. These centering elements stack one on the other Transport units 1 are centered in relation to one another and mechanically secured against slipping. The perpendicular to the above-described flange parts extending Flange parts according to FIG. 2 in turn have entry openings 12 for lifting transport tools and in the area between these two entry openings 12 additional centering elements each in the form of centering lugs 16 and centering cuts 17, the stacked transport units interlock again. As shown in Fig. 1 can by means of the straps 11 bottom part 5 and Cover part 6 firmly together with accommodation of the household appliance 2 be braced.

As is apparent from Fig. 1, are between the cover part 6 and the bottom part 5 preferably dimensionally stable in all corner areas Supports 18 provided. To insert these supports 18 can e.g. in the shell base 7 of the base and cover part 5/6 corresponding openings 19 may be provided. These supports 18 can serve to stack the weight on top of each other Transport units 1 record by the ends of these Support 18 stacked transport units on top of each other rest, these supports 18 through the openings 19 protrude through. Some variants are shown in FIGS. 4 to 7 such supports made clear. Here are the Supports each from two parts, namely from at least one partially tubular support member 20, 21 and 22 and a slightly smaller rod-shaped support part in diameter 23, 24 and 25. In the variant according to FIG. 4 the Support part 23 is also at least partially tubular and has spaced apart Bores 26 for inserting a fixing pin 27. The associated one other support part 20 has an external thread 28 and a union nut 29. Here there is a rough adjustment, i.e. a rough adjustment of the length of the column part 20 and 23 existing prop at the distance of two stacked transport units 1 instead of through correspondingly deep or less deep insertion of the Support part 23 in the support part 20 and by fixing this position by inserting the fixing pin 27. After this, a fine adjustment can take place by adjusting the union nut 29, the end of which is on the fixing pin 27 supports.

In the variant according to FIG. 5, a stepless adjustment can be made the length of the supports 21/24, characterized in that the support part 24 has an external thread or a thread-like one Has corrugation and the support part 21 with a quick release lock 31 is provided, which in turn with an eccentric cooperating hand lever 32 and one with it connected pressure piece also carrying a corrugation 33 has, which cooperates with the corrugation 30. Here, the support part 21 can have an internal thread for the also have a corrugation 30 designed as a thread.

In the variant according to FIG. 6, the support part 25 at the free end a flattened shoulder 34 which is attached to the Front edges have thread grooves 35. The lower, tubular trained support member 22 has inside Pipe shape opposite one another, provided with thread grooves, approximately quarter-circular lugs 36 and diametrically Opposing parting lines 37. By a quarter turn one of the support parts 22 or 25 is the flattened approach 34 in the circumferential gaps between the approaches 36, so that the support parts 22 and 25 are displaced relative to each other can be according to the desired length the prop. Then turn again by a quarter turn the thread grooves are engaged with each other and by tightening a threaded adapter sleeve 38 on an external thread the support part 22 through the parting lines 37 separate tube segments of the support part 22 pressed against the thread grooves of the support part 25 and thus locked the two support parts together.

In the second exemplary embodiment according to FIGS. 8 to 17 is the dash-dot indicated home appliance 2, which is preferably with a disposable packaging, for example with two foam or cardboard trays if necessary with these and the household appliance can be provided with shrink film, placed on the profile base 39 of a bottom part 40, after which on the upper side of the domestic appliance 2 a bowl-like Cover part 41 is placed. Base part 40 and cover part 41 are interconnected by elongated, according to Fig. 9 L-shaped supports 42 or 42 'in all four corners the packaging or transport unit are arranged and in also corner-side and L-shaped grooves 43 of the bottom part 40 and cover part 41 inserted and positively fixed are. The support shown in Figures 10 and 11 42 'also has an overall L-shaped angle profile, the stabilizing formations along the angle leg 42'a and both ends not profiled, L-shaped Has plug connections 42'b. Here is the form 42'a, middle support part on both sides limited by strip-like, one-piece L-parts 42'd, by which the plug connections 42'b run out. The plug connections 42'b on both sides of the central support part are of different lengths and have an L-shape several, in each case five supporting ribs 42'c in the example, which, molded in one piece, extend over a certain length extend along the plug connections 42'b in the plugging direction and obliquely tooth-like in relation to the L-shaped surfaces are placed, approximately parallel to the bisector of the L shape. When the supports 42 'are inserted into the L-shaped ones Grooves 43 of the base part and cover part engage these support ribs 42'c interlocking and form-fitting in accordingly support ribs provided for the grooves 43 (not shown) which forces e.g. Torsional forces at the Handling the transport unit from a larger area be included and an even better cohesion of the individual parts of the transport unit is given. To one to ensure distinctive composition of these parts have the plug-in connections 42'b on both sides different plug profiles, e.g. given by a coding groove 42'e in one of the plug connections 42'b, into which Assemble the parts with a corresponding coding rib in the associated groove 43 engages. The packaging unit thus formed is by straps 11 in a known manner held together, again according to the first embodiment move these straps bottom part and cover part. In Fig. 8 it can be seen that the bottom part 40th on both sides of a center support generally designated 44 Has openings 45, e.g. to drive in of lifting forks of a forklift or the like. On two opposite Outside of the bottom part 40 are located mutually parallel edge flanges 46, which are in the manner of pallet feet together with the center support 44 as a base serve for the packaging unit and also for the Transport on roller conveyors are suitable. From the profile base 39 of the bottom part 40 extend downwards integrally molded wall-like supports 47, 48, wherein the supports are parts of the aforementioned box-like central support 44 are. With their free ends they form Outriggers 47, 48 lugs 49, as below explained in more detail, run in several parallel rows and which cooperate with corresponding openings 50 in the profile base 51 of the cover part, wherein in Fig. 8 due only half-sided sectional view only two of a total of four such rows of openings can be seen. 8 is above of the packaging unit explained, the base part 40 shown a second packaging unit, to be recognized is that after placing this upper packaging unit in the direction of the arrow approaches 49 of the upper Packaging unit in the openings 50 of the cover part 41 of the lower packaging unit and intervene accordingly trained centering bevels explained below positionally fixed. With the free ends of the edge flanges 46 the upper packaging unit is supported preferably circumferential support shoulders 52 of the cover part 41 the underlying packaging unit, whereby this Support shoulders are lower than the top limit of the corresponding packaging unit, so that the total stack height, e.g. of two packaging units e.g. by 1.5 cm is less than the addition of the height dimensions of the individual Packaging units.

The bottom part 40 shown in FIGS. 12 to 15 is just like the cover part 41 as a plastic profile molded part, e.g. made of polycarbonate. From Figures 12 to 14 can be seen that the profile base 39 almost on the edge is completely moved by boundary strips 53, which limit the footprint for home appliance 2 and the home appliance 2 Secure against slipping. It can also be seen the circumferential support shoulders 52 and the entry openings 45. In the corner areas between the boundary strips 53 and the support shoulders 52 are in the Plastic material molded L-shaped grooves 43 for Recording the ends of the supports 42 (Fig. 8, 9). How in particular Fig. 13 shows that act as pallet feet Edge flanges 46 U-shaped, have on the enclosed Thigh an almost continuous outer surface and move with the free, protruding at right angles Thighs the corners of the substantially square bottom part 40. There are handle openings in the aforementioned outer surfaces 54 with wavy-shaped handles 55 or molded grip surfaces (Fig. 13 and 14), where in there are two handle openings in each of the edge flanges. For reasons of stability, the profile base 39 is through Longitudinal and transverse ribs 56 reinforced. As especially in the 13 and 15 indicated, form the wall-shaped supports 47 together with the adjacent edge flange 46 dimensionally stable, essentially box-shaped unit, as well like the supports 48 arranged in the central area also box-shaped center support 44. In the closed Front surface 57 is a recessed label surface 58 incorporated to hold a label or label for the packaging unit. The in connection with Fig. 8 approaches 49 are in the free, elongated ends of the supports 47 and 48 incorporated and form a total of four parallel to each other Rows of lugs 49, as can be clearly seen in FIG. 15, these being interrupted by recessed sections 59 Approaches 49 offset in the different rows are arranged to each other to create a distinctive association between bottom part 40 and cover part 41, that is to say a kind Coding, to get a smooth run on roller conveyors is possible. The approaches 49 extend up to Height of the ends of the edge flanges 46. The surface of the profile base 39 has a plurality of openings 60, as in particular FIGS. 12 and 15 show. These breakthroughs 60 are in the middle of the profile base 39, so that on both sides of this central area smooth and uninterrupted Sliding surfaces 61 for moving the household appliance 2 remain, which are perpendicular to the edge flanges 46 extend. Finally, as shown in FIGS. 13 to 15, have the outer surfaces of the bottom part 40, as well as those of the cover part 41 a knob structure 62 to facilitate the detection of the packaging unit by e.g. to facilitate clamp-like hoists.

The cover part 41 shown in FIGS. 16 and 17 has again a profile base 51 and one of them rectangular protruding, peripheral edge flange 63, the one parallel, inner and also circumferential support wall 64 is closely adjacent, with 64 above the support wall and edge flange 63 the circumferential support shoulder already mentioned 52 is located, as a base for one placed on it Packaging Unit. In the corner areas of the profile base 51 are in turn L-shaped grooves 65 for Insert the aforementioned supports 42. According to the Distribution of the four rows receiving the approaches 49 according to 13 and 15 and according to the arrangement of these Approaches 49 are in the profile base 51 of the cover part 41 aforementioned approaches 49 positively receiving openings 50 molded in, the elongated openings 50th are limited by funnel-like centering bevels on all sides 66 so that the openings 50 opposite the profile base 51st lie deep and with the aforementioned centering bevels 66 stacking the packaging units together Centering and fixing easier or better. In The support shoulders 52 are also at the height of the openings 50, with which the already mentioned advantage regarding the total stack height results. The inside of the surrounding retaining walls 64 result in a limitation for the domestic appliance 2 that the cover part 41 is attached. Between the openings 50 and its centering bevel 66 is the surface of the profile base 51 again often interrupted by interruptions 60. Located on the outside of the edge flange 63 there is again a recessed label area 58.

16 and 17, the cover part 41 52 web-like centering bevels in the area of the support shoulders 68, which is distributed around the entire circumference of the cover part 41 and by which when placing a packaging unit a centering of the same and an automatic Sliding onto the support shoulders 52 takes place. Further the bottom part 40 has on the underside of the profile base 39 and the cover part 41 at the top of the profile base 51 incisions 69 for flush insertion and tensioning the already mentioned tensioning straps 11.

Like the bottom part 40, there is also the top part 41 practically at least anywhere from one equally thick wall material, which by rib-like or web-like Stiffeners and recesses, e.g. 67 a high Has dimensional stability with the lowest possible proportion of material.
