Transport container designed as a lattice box

The invention relates to a transport container designed as a lattice box with a container base, lattice walls standing thereon, the front wall of which consists of two folding wall parts that can be folded out forwards around a central common horizontal axis, with a container lid provided with holding means that protrude at the edge and partially reach over and under the upper edge of the fixed lattice walls, and with at least one locking bracket that can be placed on the container front wall and overlaps its folding wall parts, which is to be connected via its upper end to the front edge of the container lid and to be locked together with the latter.

Gitterboxes are designed for transport and storage, especially for stacking a wide variety of goods. They are also used in particular as Gitterbox exchange pallets in the transport of goods and ensure that the goods to be sent do not have to be packed in special boxes and that the goods arriving at the recipient do not have to be immediately unpacked or reloaded.

in the case of such lattice box exchange pallets, the otherwise necessary return of empty containers. In order to protect the goods stored in such lattice boxes from unauthorized theft or exchange for goods of lower quality, it is known from DE 42 30 117 A1 that such lattice boxes are provided with a container lid with holding means that protrude from the edge and partially reach over and under the upper edge of the fixed side walls, as well as with a locking bracket that is placed on the front wall of the container and extends over its folding wall parts, which is to be connected via its upper end to the front edge of the container lid and locked together with the latter. In the known lattice box, the locking bracket extends over the entire height of the front wall of the container and is mounted so that it can be moved by means of articulated pins on both sides of its lower end in hinge tube-like locking projections attached to the front of the container base. This lower-end mounting of the locking bracket is not only structurally complex, but also makes it more difficult to handle in that the locking bracket must be pushed into its aligned central position in order to be locked together with the container lid and must be pulled out of the locking projections on the underside of the cage after only slight twisting around its longitudinal axis in order to be removed from the cage.

The invention is therefore based on the object of creating a lattice box of the type mentioned at the beginning, which is even simpler and more cost-effective to manufacture, in particular with regard to its locking system comprising the locking bracket. This object is achieved on the basis of a transport container of the type mentioned at the beginning in that the locking bracket is designed as a locking blade with at least one L-shaped profiled, downwardly open holding claw arranged on its rear side, which can be placed on the front wall of the container from above and at the same time brought into fork-like engagement with the front wall of the container with its holding claw. In this way, any lower attachment of the locking blade to the lower edge of the container is eliminated. Instead, the locking blade can simply be placed over the front wall of the container, with only

It is important to ensure that the retaining claw attached to the back of the cage must grip the front wall like a fork. It goes without saying that the locking blade must also grip the lower folding wall section of the cage to such an extent that it is prevented from folding forwards as far as possible.

In its simplest form, the locking blade can have a retaining claw formed on its upper end, which reaches over the upper edge of the upper folding wall part and reaches behind it more than halfway. The latter, in conjunction with the upper folding wall part, ensures that the locking blade cannot be swung forwards away from the lower folding wall part at its lower end. In principle, several retaining claws can also be attached to the back of the locking blade, which reach through the corresponding grid meshes of the upper and/or lower folding wall part, which are arranged in a row one below the other. In these cases, the retaining claws can be kept much shorter due to their greater distance from the locking blade connection point to the container lid.

The locking blade is preferably attached to the front edge of the container lid in the form of a hinge, i.e. it is permanently connected to the container lid and cannot be misplaced. When removed, the locking blade can be folded against the back of the container lid and locked there using clamps or similar arranged at the appropriate point on the underside.

However, it is also possible to provide the locking blade with a transverse support arm at its upper end and to lock it by means of the container lid that reaches over it in the locking position and is to be locked. In this case, a receiving pocket for the upper support arm of the locking blade is advantageously provided on the front of the container lid.

To close the container lid, two locking bars are preferably provided on the front side, which can be moved longitudinally in opposite directions and which, in their extended position,

with their outer ends reaching under the upper container side wall edges and are then locked together with the locking blade via their inner ends, which are then next to each other. These locking bars can penetrate longitudinal slots in the middle of the container lid edge with their inner, upwardly angled ends and have through holes here for the shackle of a padlock or a sealing wire.

Instead of the aforementioned locking bars that extend in opposite directions, the container lid can also be provided on its front with retaining clips that overlap the upper edge of the upper folding wall part at the top and front and on its back with a retaining clip flap attached in the manner of a hinge, which in its folded-down position overlaps and engages behind the upper edge of the container rear wall and can be locked. In this case too, the locking blade can be hinged to the front of the container lid or simply overlapped by the container lid in its closed position and thus locked.

The drawing shows several embodiments of lattice boxes designed according to the invention and their various locking means.

leadership form,

Fig.10 the partial front view of a grid box equipped with a container lid of Fig.9 and the

Fig.11 and 12 are sections along lines XI-XI and XII-XII of Fig.9, respectively.

The lattice box shown in Fig. 1 is provided in the conventional way with a closed base 1 and lattice side walls 2 firmly attached to it and with a fixed rear wall 3 also made of latticework. There are four support feet 4 on the base, which slightly protrude in relation to the side walls in a manner not shown in detail and therefore enable such lattice boxes to be stacked in the upper, angularly profiled edge strips 5 of the lower lattice box. The front wall 7 of the lattice box consists of two folding wall parts that can be folded out forwards around a common central horizontal axis 6, namely the upper folding wall part 7' and the lower folding wall part 7''.

In order to protect the goods to be stored and transported in such lattice boxes from unauthorized access by third parties, the lattice box must be closed at the top and front wall. The lid 8 and the locking blade 9 connected to it via its upper end serve this purpose. The lid 8 has holding means on its narrow sides and on the back in the form of holding strips 8', 8'' formed on the container lid edges. These holding strips are each more than half as long as the corresponding container lid edges. In the closed position of the container lid 8, which preferably also has a lattice-like structure but can also be made of sheet metal with individual grip recesses arranged in it, the rear holding strip 8 ' ' grips under the upper rear edge 3 ' of the container rear wall 3, while the two lateral holding strips 8' grip over the upper edges 2' of the side walls 2 or rest on them.

As shown in particular in Fig.2 and 3, the container lid 8 is provided on its front side 8''' with two locking rods 11, 12 which are longitudinally displaceable in opposite directions in guide eyes 10 mounted on the underside of the lid. These

In their extended position, they reach at their outer ends, e.g. 11', under the upper container side wall edges, specifically under their front corners 2'. The inner ends H'' or 12"' of the locking bars 11, 12 are angled upwards and thus pass through the longitudinal slots 13, 13' in the middle of the container lid edge 8' ' ', which are offset from one another accordingly. In the extended position of the two locking bars 11, 12 shown in Fig. 2, their angled ends H'' or 12'' are close to one another. A fork-like retaining clip 14 can be welded to one end of the locking bar H'', which in the extended position of the two locking bars 11, 12 shown, encompasses the other angled locking bar end 12''. In the two legs of the retaining clip 14, there are through-holes 15 through which the shackle of a padlock or a sealing wire or similar locking means can be inserted, so that the two locking bars 11,12 and thus the container lid 8 as a whole can be securely closed in this position.

The locking blade 9, which spans the front folding wall parts 7', 7'', is provided with a bearing eye 9' at its upper end, via which it is pivotably mounted on the bearing bracket 16 firmly attached to the underside of the container lid edge 8''' and is firmly connected to the container lid 8 via a corresponding folding joint. At its upper end, on the back of the locking blade 9, there is an L-shaped, downwardly open retaining claw 17, which reaches over the upper edge 18 of the upper folding wall part 7' and also reaches behind the latter by more than half. As Fig. 4 clearly shows, the locking blade 9 designed in this way can be placed on the container front wall 7 from above and at the same time brought into a fork-like grip with the container front wall or its upper folding wall part 7' with its retaining claw 17. By tightly engaging the locking blade with its rear holding claw 17 over the upper hinged wall part 7', the locking blade 9, which is firmly hinged to the container lid 8, is secured against pivoting forwards, so that the locking blade 9 with its lower part 9'' simultaneously securely locks the lower hinged wall part 7'' in its closed position.

The locking blade 9a shown in Fig.5 has a transverse support arm 9a' at its upper end instead of a hinge eye, by means of which it can be locked in its inserted position by the container lid 8a that overlaps it and is to be locked. For this purpose, there is a receiving pocket 8a' on the front of the container lid 8a, which in the locked position reaches over the transverse support arm 9a' of the locking blade 9a and thus allows it to be securely locked, for which purpose the locking bar ends, as shown in Fig.6, are of the same nature as in the case of the previously described embodiment.

The locking blade 9b shown in Figs. 7 and 8 differs from those described above in that it has several, but comparatively short, retaining claws 17b on its back, which grip the corresponding grid meshes 18, 18' of the upper and lower folding wall parts 7' and 7'', which are arranged in a row one below the other, and grip behind their correspondingly located grid wire area. In this way, too, sufficient locking of the two folding wall parts '7', 7'' can be achieved. It goes without saying that in this case too, the locking blade 9b could be provided with a transverse support arm 9a' instead of an upper hinge eye 9b' and could therefore only be held in the closed position by the container lid 8 by resting it on it.

In the embodiment shown in Figs. 9 to 12, the container lid 8c is provided on its front side 8c' with two retaining clips 20 which overlap the upper edge 18 of the upper folding wall part 7' on the top and front side, while on its back side a retaining clip flap 21 is provided which is attached in the manner of a swivel joint and which, in its folded-down position shown in Fig. 12, overlaps and reaches behind the upper edge 3c' of the container rear wall 3c. The articulation point of the retaining clip flap 21 on the rear edge of the lid is designated 22. In the leg 21' of the clip 21 which overlaps the rear wall, there are again two through holes 15 for the bracket which extends through and behind the lattice box rear wall 3.

gel of a padlock 23 indicated by dash-dot lines.

On the front side 8c' of the container lid 8c, a hinge bracket 16c is attached, which forms the pivot axis for a locking blade 9c, which is also attached to its upper end in the manner of a hinge. As is easily understandable, in this case too, the container lid 8c with its locking blade 9c hinged to the front can be perfectly closed by the locking retaining clip flap 21.
