EP3426566B1 - Transport box - Google Patents

Description

The invention relates to a transport box according to the preamble of claim 1.

Many types of transport boxes are required to transport components to a customer without damage. The bottoms of the boxes are very often provided with bulges and domes in order to hold the components securely during transport. This corresponds to the principle of an egg box.

More flexible transport containers are also known, in which compartments are formed within the container by insertable inserts.

From the CN 102 020 069 B is a generic transport box with domes on the floor.

In the European patent application EP 0 505 427 A1 describes a transport container in which there are recesses in its base in a grid into which simple holding elements can be inserted, the position of which can be adapted to the goods to be transported.

From the utility model DE 20 2006 016 566 U1 a tray for use in a transport container is known, in which compartments are formed in the tray and thus in the transport container by plug-in rods, the size of which is adapted to the goods to be transported.

From the utility model DE 8 808 808 U1 a transport box with insert is known in which mounting slats are attached to strips of the inner walls, into which notches for components to be accommodated are made.

Also in the utility model DE 8 420 430 U1 describes a transport container with smooth inner walls, in which an insert made of inserted dividing strips is inserted, and thus provides compartments in the required size.

Further transport boxes are in the US 4,261,464 A , the GB 2 023 102 A and the DE 26 53 269 A1 described.

The invention has for its object to disclose a simple transport box, in which brackets for flat, vertical components can be provided by means of division strips attached to the side walls.

This object is solved by the features of claim 1. Embodiments of the invention are described in the subclaims.

The transport box is used for packaging flat, essentially rectangular components. Such components are, for example, plastic frames for switches. However, boards, glass panes, ceramic plates, sheet metal sections or the like can also be transported with the transport box.

The transport box has a bottom, and four side walls, which have webs in the direction of the bottom in a certain grid dimension, between which grooves are formed. Dividing strips can be inserted into these grooves, which divide the transport box into compartments.

The transport box is characterized in that the dividing strips have the same webs and grooves on both sides in the same grid dimension as in the side walls and the components are held vertically spaced between opposite grooves. In this way, several components of the same width can be spaced apart in each case a staked out compartment. Components with the same or a different width can be held in an adjacent compartment.

The dividing strips can be positively inserted at their ends into the grooves by means of a spring designed as a bead. The division strips thus hold securely in the grooves. The bottom of the transport box has domes on which the dividing strips are supported and are thus held in a straight line. This gives the dividing strips a secure stability and prevents them from bending during transport.

The dividing strips are advantageously provided in two variants.
In one embodiment, the springs are formed in alignment with the center line of the dividing strip. In a further embodiment, the springs are formed offset to the center line of the graduation strip. Due to the offset, the distances between the dividing strips and also the side wall can be varied and can thus be more precisely adapted to the desired widths.

The walls of the grooves in the side walls and the dividing strips are concave. This results in a further possibility of varying the distance, depending on the thickness of the component to be held.

The webs and the dividing strips have about 60% of the height of the side walls. The components are thus held securely. However, it is also possible for the components to be thicker in the free area.

The upper edge of the side walls is designed as a stack edge. So the transport boxes can be stacked on top of each other and then form a composite.

In one embodiment, the transport box is designed such that it is designed as an inner box of a transport box. In this way, standardized transport boxes can be equipped with holders for many components, by means of which the components are kept at a distance.

The transport box and the dividing strips are preferably made of plastic, here preferably polypropylene or polystyrene. However, other materials such as wood, metal or cardboard are also possible.

The size of the transport box is advantageously chosen so that its external dimensions correspond to a smooth division ratio of the basic dimensions of a standardized pallet.

For example, several groups of stacked transport boxes can be transported on one Euro pallet.

Detailed views of the ends of graduation strips.

The Fig. 1 shows a transport box 1 in an oblique view. The side walls 2 are provided with grooves 5 which do not extend to the edge 4 of the stack. The dividing strips 8 are inserted into the grooves 5. They are further stabilized by the dome 7 in the floor 3. The components 6 are held in the grooves 5 in the side walls and the grooves 11 in the partition strips.

In the Fig. 2 and Fig. 3 are excerpts from the Fig. 1 shown. In Fig. 2 is the cutout on the side and in Fig. 3 the cutout is shown on a corner of the transport box.

In the grooves 5 on the side wall 2 division strips with a symmetrical spring 9 and asymmetrical spring 10 are used. The components 6 used in the grooves 11 of the dividing strips 8 extend down to the floor 3 next to the domes 7. The components 6 can now have different widths, depending on whether dividing strips 8 with a symmetrical spring 9 or an asymmetrical spring 10 are used.

In the 4a to 4f the possible widths for the components when using the symmetrical and asymmetrical division strips are given as examples.
In the example shown here, with an offset of the springs of 5 mm, the possible widths at the edge are 29.5 mm, 34.5 mm and 39.5 mm.

The possible widths between the division strips in the case of the connectors shown here are then 33 mm, 38 mm, 43 mm, 48 mm and 53 mm.
Together with the concave shape of the grooves, many widths are possible for the components.

Fig. 5 shows ends of two graduation strips 8 in an oblique view. In the left graduation strip 8, the spring 10 is asymmetrical. In the right graduation strip 8, the spring 9 is formed symmetrically. In the symmetrical design, the grooves 11 extend into the upper bead 12 of the dividing strips 8. In the unsymmetrical design, the grooves 11 extend further into the upper bead 12 of the dividing strips 8 on one side, while the upper bead 12 on the other side is not cut.
