Description

The invention relates to an insert ring for a pallet box, in particular a lattice box, with four side walls, wherein at least one side wall has holding means for a flexible Gefacheanordnung, and a pallet box with such an insert ring.

A pallet box is out of the WO 97/31830 A1 known. The pallet box is intended for transporting automotive parts and has a pallet base that can be handled by a forklift. On the pallet floor a collapsible wall ring is placed. On the Wandungsring a lid is placed, which closes the interior of the Wandungsringes. The wall ring has four flat side walls, which are foldable via edge hinges. On two opposite side walls holding rails are provided on the inside, to which a flexible Gefacheanordnung is attached for receiving corresponding automotive parts.

The object of the invention is to provide an insert ring and a pallet box of the type mentioned, which are easy to manufacture and have a stable structure.

This object is achieved in that at least two opposite side walls are designed as plastic surface parts produced in a twinsheet method, and that the two remaining side walls are at least partially formed by dimensionally stable transverse struts, which are connected to the plastic surface parts. Characterized in that the plastic surface parts are produced in a twinsheet process, the plastic surface parts are double-walled designed from an inner shell and an outer shell to form hollow chambers or cavities between the inner shell and the outer shell of the plastic surface part. The terms "inside" and "outside" are based on the established functional position of the insert ring, wherein "inside" the inwardly facing side of the insert ring and "outside" define the outwardly facing side of the insert ring. The solution according to the invention is suitable in a particularly advantageous manner for insert rings, the size of which are matched to standardized grid boxes for the storage and transport of supplied parts for the automotive industry.

Advantageously, the insert rings are intended to be inserted into a corresponding grid box or a comparable pallet box made of a plastic material. In both cases, in the erected functional position, the side walls of the insert ring directly against corresponding inner walls of the grid box or pallet box. Alternatively, it is provided according to the invention to execute the insert rings directly as wall rings for corresponding pallet boxes. In this case, a corresponding insert ring is placed with its underside on a corresponding pallet floor. An upper side of the insert ring is closed by an attachable lid.

The lid is designed relative to the pallet base so that it can also be placed directly on the pallet base. The production of the plastic surface parts in a twinsheet process means that two sheets are made of a thermoplastic material and introduced into a mold in which at the same time by deep drawing of the two plastic plates and corresponding welding of the plastic plates at its edge region and at intermediate portions together generates the bivalve surface part becomes. The transverse struts form at least partial regions of the side walls of the insert ring and are preferably designed as metallic hollow profiles, in particular of a steel alloy.

In an embodiment of the invention, the plastic surface parts are provided with upright extending buckling areas to allow collapsing and unfolding of the insert ring. The edgewise kink areas are preferably formed by film hinges, which are integrally molded with the plastic surface parts.

In a further embodiment of the invention, at least one of the plastic surface parts is provided with a flap portion which is connected by means of a transverse film hinge with the plastic surface part. The flap portion is connected only in the region of the film hinge with the plastic surface part. The folding section makes it possible to gain access to the interior of the insert ring. Preferably, the film hinge is arranged such that in the folded state of the flap portion of the associated side wall portion of the plastic tile part is additionally stiffened and reinforced. In the folded state, the flap section closes the access opening to the interior of the insert ring. About the access opening is the introduction or removal of a corresponding cargo, in particular an automotive supply part enabled.

In a further embodiment of the invention, the cross struts are embedded in groove-like recesses of wall sections of the plastic surface parts and fixed by means of fastening elements. As a result, the transverse struts do not protrude beyond a corresponding surface contour of the plastic surface parts. The design allows a space-saving arrangement of the cross braces. The Embedding the crossbars additionally ensures a stiffening of the wall sections of the plastic surface parts.

In a further embodiment of the invention, the cross struts are provided with the holding means for the flexible Gefacheanordnung. Additional support or support rails for the flexible Gefacheanordnung be avoided. Preferably, the cross struts are provided with inwardly directed longitudinal grooves in which corresponding slide or sliding elements are displaceable, with which the flexible Gefacheanordnung is connected. The grooves of the transverse struts are preferably designed in the manner of curtain rails. The slide or sliding elements for holding the flexible Gefacheanordnung are designed in the manner of a curtain suspension.

In a further embodiment of the invention, the upright extending buckling areas at corner regions of the insert ring on each two spaced parallel crease lines which define a support back between them, which defines a free space between corresponding wall sections of the plastic surface parts in the folded state of the insert ring. This ensures that even in the folded state of the insert ring enough space is available to accommodate the flexible Gefacheanordnung between corresponding wall sections of the plastic surface parts. This ensures that the flexible Gefacheanordnung does not have to be removed from the cross braces before folding or folding the insert ring. Rather, the Gefacheanordnung can remain connected in the folded state of the insert ring with the side walls, in particular with the cross struts.

In a further embodiment of the invention, the bending lines are designed by film hinges, which are flanked on the inside by miter edge surfaces of the plastic surface parts, in particular miter angle of 45 ° are provided. The miter edge surfaces are based on each other in the folded state, whereby the corresponding wall sections of the plastic surface parts are aligned at right angles relative to each other and relative to the support bridges in the folded state.

The insert ring according to the invention can be used in a particularly advantageous manner in a pallet box, in particular in a grid box made of steel. In this case, the insert ring from above, d. H. from the open side of the pallet box, inserted until its bottom edge rests on the pallet floor. The side walls of the insert ring are matched in height and width to the side walls of the pallet box in such a way that in the installed functional state of the insert ring, the side walls lie substantially flat against the inner walls of the pallet box. The pallet box has the dimensions of a standardized mesh box, which has a width of 835 mm, a length of 1240 mm and a height of 970 mm. The pallet box represents a loading aid for the storage, transport and conveyor technology. Each pallet box has four feet at the bottom of its pallet base, which must enable an attack of a forklift truck from all four sides.

An insert ring 1 for a pallet box is according to the 1 to 7 made of two plastic parts 3 as well as several cross struts 4 composed, as 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 is in the insert ring 1 a flexible compartment arrangement 2 provided consisting of several loops of a textile surface sheet. The loops form fold-like pockets and are each arranged parallel next to each other. The flexible compartment arrangement 2 is suspended by means of tension strands and on the opposite side walls C, D of the insert ring 1 held.

The two opposite plastic surface parts 3 are designed identically to each other. Each plastic surface part 3 is double-walled in Twinsheet construction. In this case, each of the two plastic surface parts 3 one to the center of the insert ring 1 facing inner shell as well as an outwardly directed external switch, which in a basically known manner by common deep drawing in a Twinsheet method to form cavities and connecting seams to the respective plastic surface part 3 are made.

Based on 7 is the design of the plastic surface part 3 good to see. The opposite plastic surface part 3 of the insert ring 1 is identically designed. Each plastic surface part 3 has a side wall portion 5 on, by an upright bend line 6 designed to be foldable shared. The sidewall section 5 is provided in the region of its upper half with a rectangular cutout, partly by a folding section 7 is closable. The folding section 7 is integral with the plastic surface part 3 connected and is in the range of a film hinge S, relative to the vertical axis of the plastic tile part 3 transverse, with the side wall portion 5 connected. Also the folding section 7 has one with the bend line 6 coaxially aligned bend line 6a on. Both the break line 6a as well as the break line 6 are each formed by an integrally molded film hinge with the outer shell of the plastic surface part 3 flees. Starting from the inner shell, both the Seitenwandungsabschnitt 5 as well as the folding section 7 unspecified miter edge surfaces on the bend line 6 . 6a Flank on both sides in an angled orientation of 45 °. The film hinge S, with the folding section 7 on the side wall portion 5 is held at the height of the inner shell of the plastic surface part 3 intended. At the opposite edge sides of the Seitenwandungsabschnittes 5 each includes an edgewise over the entire height of the Seitenwandungsabschnittes 5 running crease line 10 on, which is designed as provided at the level of the outer shell of the film hinge. From the inner shell forth each of the two fold lines 10 on opposite sides of the side wall portion 5 flanked by Miter edge surfaces, which are identical to the miter edge surfaces of the bend line 6 are executed.

Each outward closes at each bend line 10 a narrow support back 11 on, extending over the entire height of the plastic surface part 3 extends and out through another crease line 9 is limited. The bend line 9 forms in erected functional position of the insert ring 1 one corner of the insert ring 1 , Also the bend line 9 is formed by a positioned in the outer shell of the film hinge, over the entire height of the plastic surface part 3 goes through and parallel to the fold lines 10 . 6 is aligned. From the inner shell ago, the film hinge 9 flanked by bevel edge surfaces oriented at a 45 ° angle. The opposite outer wall sections of the plastic surface part 3 be from opposite the support bridges 11 wider holding sections 8th formed over the entire height of the plastic surface part 3 form extended wall sections. Laterally outward, each holding section 8th a bevel edge surface oriented at an angle of 45 °. The holding sections 8th are with integrally molded transverse grooves 14 provided that exceeds the height of the holding sections 8th are arranged distributed. In the illustrated embodiment, a total of six transverse grooves 14 provided for receiving dimensionally stable cross struts 4 are formed. Every cross groove 14 is inside of the support back 11 a graduated recess arranged at the same height 15 associated, in the rectangularly constructed state of the insert ring corresponding ends of the dimensionally stable cross struts 14 take up.

Characterized in that a transverse film hinge S of the flap portion 7 in the region of the inner shell of the plastic surface part 3 is provided, the folding section 7 be pivoted inward by 180 °, reducing its crease line 6a is aligned opposite to the crease line 6 the associated side wall section 5 ( 2 . 5 . 6 ). This forms the folding section 7 in the folded-in state, a reinforcement and stiffening for the side wall section 5 ,

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

As based on the 2 is recognizable, are the cross struts 4 in the holding sections 8th the opposite plastic surface parts 3 Received flush, so they do not have an inner surface or inner contour of the holding sections 8th protrude inwards. The cross struts 4 are with to the center of the insert ring 1 towards open longitudinal grooves 12 provided in which appropriate holding means 13 the tension strands of the Gefacheanordnung 2 are held.

As based on the 5 and 6 are recognizable, which form the fold lines 9 flanking miter edge surfaces of the plastic surface parts 3 in the erected functional state of the insert ring 1 Support surfaces to the rectangular orientation of the corners of the insert 1 to support.

The insert ring 1 is with or without integrated partition arrangement 2 in a folded state of rest according to the 3 and 4 transferable. For this purpose, the folding sections are in a simple manner 7 pivoted from its inwardly folded reinforcing position again 180 ° upwards, thereby according to 7 with the outer surface contours of the respective Seitenwandungsabschnittes 5 aligned. Subsequently, the Seitenwandungsabschnitte 5 around its mean crease line 6 . 6a pressed inwards towards the middle. Once a left and a right half of each side wall section 5 including the two-part folding sections 7 lie flat against each other with their outer sides, is the folded rest position of the insert ring 1 according to the 3 and 4 reached. As based on the 3 and 4 recognizable, remains due to the support back 11 between through the cross struts 4 At least over part of its width formed side walls C, D and the folded Seitenwandungsabschnitten 5 a clearance, because the holding sections 8th relative to the support backs 11 aligned at 90 ° and also the Seitenwandungsabschnitte 5 in about 90 ° inside lying to the cross struts 4 at the support back 11 are supported. The creases and thus the associated film hinges are formed so flexible that a slightly oblique orientation of the folded side wall sections 5 according to 4 is possible. This allows the opposite side wall sections 5 with the side walls A, B overlay each other, as shown by the 3 and 4 is recognizable. The between the cross struts 4 and the associated holding portions 8th the opposite side walls C, D remaining clearance is sufficient to the flexible Gefacheanordnung 2 in their folded state.

The two side walls C, D are accordingly through the respective two holding sections 8th the opposite plastic surface parts 3 as well as through the six cross struts 4 formed in the transverse grooves 14 the two holding sections 8th the opposite plastic surface parts 5 are embedded.

The insert ring 1 indicates due to the twin-sheet construction of the plastic surface parts 3 as well as due to the dimensionally stable cross struts 4 a high rigidity and stability. Because of the cross struts 4 the opposite side walls C, D between the opposite holding portions 8th the plastic surface parts 3 Complete form, a weight saving is achieved. Because the cross struts 4 Although in a common wall plane parallel to each other, but at a distance from each other, is arranged, it is possible in the region of the side walls C, D by the cross struts 4 through the inside of the insert ring 1 look into it.
