Intermediate floor for Euro pallet box

The invention relates to an intermediate floor specifically for Euro pallet cages.

The EUROGITTERBOX has been used as a standard load carrier by freight forwarders, automobile manufacturers, and in the metal, wood and materials industries for many years.

Every small and medium-sized company owns some of these load carriers.

Due to the wide range of uses of pallets, the range of items that can be transported on the pallets is of very different geometric shapes.

The bodywork of trucks is also designed in terms of length and width dimensions on the basis of a number of EUROGITTERBOXES.

The pallets are subjected to a lot of stress in day-to-day business for frequent goods handling (for example in the general cargo sector) , so that damage to the items being transported is not uncommon. It is often required that parts be spatially separated from one another in order to avoid friction and pressure points on one another (e.g. for driver seat bellows for trucks) .

The current state of the art uses cardboard, polystyrene, special load carriers and variable wooden pallets, which experience has shown to be very impractical or unsuitable. These have the disadvantage that they cannot be stacked five high, cannot be exchanged full for empty at any time during a commercial delivery and cannot be left outside for an unlimited period of time due to weather conditions. Finding the right selection of common load carriers today involves considerable effort and expense, as special and specialized load carriers are not necessarily offered at low prices and cardboard and polystyrene do not protect against the weight of the items being transported. At the same time, protective packaging is often no longer reusable after it has gotten wet once. During transport and storage, it is also often found that the pallets are only 1/3 full in terms of volume, as it is not possible to effectively and optimally divide the pallet.

The high demands of the current packaging regulations require reusable pallets that can be used flexibly and make a significant contribution to reducing packaging waste.

The introductory sentences quickly make it clear that the transport and shipping business is difficult to imagine without these load carriers and that the degree of use and flexibility of the pallet is limited. In addition, the aim should be to use existing standards and to expand them as far as possible.

The invention is based on the task of creating a suitable floor for dividing up lattice boxes which, on the one hand, can accommodate the required load-bearing capacity of approx. 250 kilograms and, at the same time, is practical, simple and safe to handle. In addition, no external changes to a EURO lattice box 1200 x 800 x 820 are to be made and the aforementioned disadvantages are to be eliminated. At the same time, the required floor is intended to make the use of the pallet more attractive and flexible.

The design of the intermediate floor provides that the material is preferably made from a recyclable plastic as an injection-molded part. This is firstly due to the mirror-image rib-like design of the individual floor half (10) and the draft angle of 1° (4) on the underside of the floor. To produce the entire intermediate floor, only a single plastic injection molding tool is required. Left side = right side of the intermediate floor. The choice of plastic is secondly reinforced by the requirement to ensure a moisture-repellent and weather-resistant surface.

At the same time, this invention offers a high load-bearing capacity with a low weight due to the grid-like ribbing on the underside of the floor.

An advantageous design on the front sides of the intermediate floor provides for the floor to be fixed at the inserted height or the desired height by means of 7 centering prongs (1) in the grid of the transverse sides (14) of a GITTERBOX (12).

For the practical use of the intermediate floor, this means that an intermediate floor (11) can be inserted into the existing (round steel) welded grid bars of the EUROGITTERBOX with just one movement (each at a distance of approx. 40mm) . This also offers the advantage of setting up several levels within the grid box (depending on the geometric physical size of the part to be transported). The folding intermediate floor can be inserted effortlessly due to its low weight, the hand grips on the top and the centering prongs on the front sides.

Another advantageous design is the folding mechanism and the achieved internal dimensions of the floor when assembled. Due to the welded-on attachment frame (13) (smaller than the internal dimensions of the box, the supporting frame for stackability) of a lattice box, it is almost impossible to construct or insert an intermediate floor that has or fills the full length and width dimensions of the box. The solution to the problem is achieved here by using a folding mechanism in the middle of the intermediate floor. This makes it possible to insert the intermediate floor from above or from the side (by opening the loading flap of a lattice box) and to achieve 100% use of the area within the lattice box. As previously mentioned, the entire floor consists of two halves (10) which are constructed in such a way that they can be either the "left side" or the "right side" of the entire floor. If you now take two individual halves and push them together at the articulated arms (3), then fix them together by inserting a round steel bar 0.5mm (9) through the center axis of the articulated arms (hinge construction) , you get a complete framework... : : :*· * . ^: : : : : *: 2 \

Only now can the intermediate floor be used and cleaned as a complete unit. The support surfaces (2) are designed in such a way that the two floor halves rest on and on each other when unfolded (in use). This ensures that the required weight-bearing capacity of the entire floor is guaranteed.

Another advantageous design is the articulated arms (3) for the folding radius of the base. These are designed in such a way that the base can be folded up by 180 ⁰ C. This means that an article that is rather large in use becomes a simple article with half of its external dimensions reduced (crucial in the area of empties, return transport, storage, etc.).
