An insert ring 1 for a pallet box is in accordance with Fig. 1 to 7 composed of two plastic surface parts 3 and a plurality of transverse struts 4, as will be described in more detail below. The insert ring 1 has a rectangular base and forms a total of four side walls A, B, C, D. Within the four side walls A to D, a flexible Gefacheanordnung 2 is provided in the insert ring 1, which consists of several loops of a textile surface web. The loops form fold-like pockets and are each arranged parallel next to each other. The flexible Gefacheanordnung 2 can be fixed or suspended by means of tension strands or by means of attached to the Gefacheanordnung 2 hooks or eyes on the inner sides of the insert ring 1 and is thus held on at least two opposite side walls C, D of the insert ring 1.

The two opposing plastic surface portions 3 are identical to each other. Each plastic surface part 3 is double-walled in a twin-sheet construction. In this case, each of the two plastic surface parts 3 has an inner shell facing the center of the insert ring 1 and an outward outer circuit, which are produced in a basically known manner by common deep drawing in a twinsheet process to form cavities and connecting seams to the respective plastic surface part 3.

Based on Fig. 7 The design of the plastic surface part 3 is clearly visible. The opposite plastic surface part 3 of the insert ring 1 is designed identically. Each plastic tile part 3 has a side wall portion 5, which is designed to be hinged divided by an upright bend line 6. The side wall portion 5 is provided in the region of its upper half with a rectangular cutout which is partially closed by a flap portion 7. The flap section 7 is integrally connected to the plastic surface part 3 and is connected to the side wall section 5 in the region of a film hinge S, which runs transversely relative to the vertical axis of the plastic surface part 3. Also, the flap portion 7 has a coaxially aligned with the bending line 6 crease line 6a. Both the bending line 6a and the bending line 6 are each formed by an integrally molded film hinge, which is aligned with the outer shell of the plastic surface part 3. Starting from the inner shell, both the Seitenwandungsabschnitt 5 and the flap portion 7 unspecified miter edge surfaces flanking the crease line 6, 6a in an angled orientation of 45 ° on both sides. The film hinge S, with which the folding portion 7 is held on the side wall portion 5, is provided at the height of the inner shell of the plastic surface part 3. At the opposite edge sides of the Seitenwandungsabschnittes 5 includes in each case an upright over the entire height of the Seitenwandungsabschnittes 5 extending crease line 10, which is designed as provided at the level of the outer shell film hinge. From the inner shell, each of the two crease lines 10 is flanked on opposite sides of the side wall section 5 by miter edge surfaces which are identical to the miter edge surfaces of the crease line 6.

Each outwardly connects to each bend line 10 a narrow support back 11, which extends over the entire height of the plastic surface part 3 and is bounded on the outside by a further crease line 9. The crease line 9 forms in deployed functional position of the insert ring 1 each have a corner of the insert ring 1. The crease line 9 is formed by a positioned in the outer shell of the film hinge, which passes over the entire height of the plastic surface part 3 and aligned parallel to the fold lines 10, 6 is. From the inner shell forth the film hinge 9 is flanked by aligned at a 45 ° angle miter edge surfaces. The opposite outer wall portions of the plastic surface part 3 are opposite formed the support back 11 wider holding portions 8, which form over the entire height of the plastic surface part 3 extended wall sections. Laterally outward, each holding section 8 has a bevel edge surface oriented at an angle of 45 °. The holding portions 8 are provided with integrally molded transverse grooves 14, which are arranged distributed over the height of the holding portions 8. In the illustrated embodiment, a total of six transverse grooves 14 are provided, which are formed for receiving dimensionally stable transverse struts 4. Each transverse groove 14 is assigned to the inner side of the support back 11 a arranged at the same height graduation recess 15 which receive corresponding rectangular ends of the insert ring front ends of the dimensionally stable transverse struts 14.

Characterized in that a transversely extending film hinge S of the flap portion 7 is provided in the region of the inner shell of the plastic surface part 3, the flap portion 7 can be pivoted by 180 ° inwardly, whereby its crease line 6a is oriented opposite to the crease line 6 of the associated Seitenwandungsabschnittes 5 (Fig. Fig. 2 . 5 . 6 ). As a result, the folding section 7 forms a reinforcement and stiffening for the side wall section 5 in the folded-over state.

In the transverse grooves 14 of the two opposing Kunststofflächenteile 3 six dimensionally stable transverse struts 4 are inserted on opposite sides of the insert ring 1, which are executed in the illustrated embodiment as metallic hollow sections with quadrangular cross-section. Preferably, the cross struts are made of steel. However, it is also possible to produce the transverse struts 4 from a light metal, in particular an aluminum alloy, or from a composite fiber material. By the cross struts 4, the two opposite plastic surface parts 3 are interconnected, as based on Fig. 1 to 3 is clearly recognizable. The transverse struts 4 are each designed in their cross-sectional profile such that they can be embedded flush in the provided with square light cross-section transverse grooves 14. For fixing the transverse struts 4 in the transverse grooves 14 of the opposite holding portions 8 of the plastic surface parts 3 are fastening means provided in the form of rivets or the like. The fastening means are preferably positively effective. It is also possible to provide screw connections and / or integrally formed latching profiles as fastening means.

As based on the Fig. 2 can be seen, the transverse struts 4 are flush received in the holding portions 8 of the opposite plastic surface portions 3, so that they do not protrude beyond an inner surface or inner contour of the holding portions 8 inward. The cross struts 4 are provided with the middle of the insert ring 1 open towards longitudinal grooves 12 in which corresponding holding means 13 of the hooks, loops or tension strands of the Gefacheanordnung 2 are held.

As based on the Fig. 5 and 6 can be seen, the miter lines 9 flanking miter edge surfaces of the plastic surface parts 3 in erected functional state of the insert ring 1 support surfaces to support the rectangular orientation of the corners of the insert 1.

The insert ring 1 is with or without integrated Gefacheanordnung 2 in a folded state of rest according to the Fig. 3 and 4 transferable. For this purpose, the folding portions 7 are pivoted back from their inwardly folded reinforcing position by 180 ° upwards in a simple manner, thereby according to Fig. 7 are aligned with the outer surface contours of the respective side wall section 5. Subsequently, the side wall sections 5 are pressed inwards around their middle crease line 6, 6a towards the center. Once a left and a right half of each Seitenwandungsabschnittes 5 including the two-part folding sections 7 abut each other with their outer sides, the folded-rest position of the insert ring 1 according to the Fig. 3 and 4 reached. As based on the Fig. 3 and 4 can be seen remains due to the support back 11 between the formed by the cross braces 4 at least over part of their width side walls C, D and the folded Seitenwandungsabschnitten 5 a clearance, since the holding sections 8 are aligned relative to the support back 11 by 90 ° and the Seitenwandungsabschnitte 5 are supported at about 90 ° inside lying to the cross braces 4 on the support back 11. The crease lines and thus the associated film hinges are designed so flexible that a slightly oblique orientation of the folded side wall portions 5 according to Fig. 4 is possible. Thereby, the opposite side wall portions 5 with the side walls A, B superimpose each other, as shown in FIG Fig. 3 and 4 is recognizable. The clearance remaining between the cross struts 4 and the associated holding portions 8 of the opposite side walls C, D is sufficient to receive the flexible dish assembly 2 in its folded state.

The two side walls C, D are therefore formed by the respective two holding portions 8 of the opposite plastic surface portions 3 and by the six transverse struts 4, which are embedded in the transverse grooves 14 of the two holding portions 8 of the opposite plastic surface portions 5.

The insert ring 1 has due to the twin-sheet construction of the plastic surface parts 3 and due to the dimensionally stable cross struts 4 high rigidity and stability. Characterized in that the transverse struts 4 completely form the opposite side walls C, D between the opposite holding portions 8 of the plastic surface parts 3, a weight saving is achieved. Although the transverse struts 4 are arranged in a common wall plane parallel to one another but at a distance from one another, it is possible to see through the transverse struts 4 into the interior of the insert ring 1 in the region of the side walls C, D.

A pallet box H after the 8 to 12 serves to accommodate at least one insert ring 1 after the Fig. 1 to 7 in its established functional position ( Fig. 8 ) or in its folded resting position ( Fig. 9 and 12 ). The pallet box H has standard dimensions used in the automotive industry or in the household appliance industry. The pallet box H is made of plastic in the illustrated embodiment and at least a hinged side wall provided. As based on the Fig. 8 It can be seen, an insert ring 1 can be used in a functional condition erected including its Gefacheanordnung 2 from above into the upwardly open pallet box H. The insert ring 1 is matched to the inner dimensions of the pallet box H so that it rests in the established functional state essentially free of play on all four side walls of the cuboid box H at least substantially flush. Additional fastening means for securing the insert ring 1 in the installed functional state within the pallet box H are thereby avoided.

As based on the Fig. 9 can be seen, the insert ring 1 can also be folded. This folding can take place both within the pallet box H and outside the pallet box H. In the folded state, the insert ring is arranged standing in the pallet box H. According to the 10 and 11 it can be easily removed upwards. The inherent stability of the insert ring 1 even in folded state of rest allows easy handling by the insert ring 1 can be positioned either upright in the pallet box H or can be easily pulled up from the pallet box H ( 10 and 11 ). In folded functional state, it is possible to accommodate a total of fourteen insert rings 1 standing side by side within the pallet box H. In an empty and folded state, a plurality of insert rings 1 can thus be transported through a pallet box H. Again, no additional fasteners are necessary. Rather, the fourteen insert rings 1 are stacked side by side in such a way that they substantially accurately fill the inner dimensions of the pallet box H.
