Description

[0001] The present invention relates to a roll container, in particular a roll pallet, comprising a container base and two side walls. The side walls are arranged longitudinally on opposite sides of the container base and each comprise a first longitudinal beam arranged in a first side wall opening of the container base and a second longitudinal beam arranged in a second side wall opening of the container base.

[0002] Roll containers are known in various designs from the prior art. The known roll containers usually comprise a container base to which two side walls are releasably fixed on two longitudinally opposite sides. For storage and transport, empty roll containers are usually disassembled or dismantled, i.e. the side walls are removed from the container bases. The removed side walls are then stored next to each other on a container base of an assembled roll container. Since the side walls are only placed on the container base, they can fall off the roll container, for example, during transport. In addition, placing the side walls on the roll container can cause damage to the roll container. In particular, the disassembled side walls are usually leaned against a side wall of the assembled, stored roll container for storage.This causes bending stress in the insertion areas of the container base, where the side wall is mounted to the container base. This bending stress can result in tearing and / or breaking off of corner areas of the container base.

[0003] The object of the present invention is to provide a roll container on which further roll containers, in particular side walls of further roll containers, can be safely stored and transported in a simple manner without damaging the roll container.

[0004] This object is achieved according to the invention by the roll container having the features of claim 1.

[0005] According to the invention, a roll container, in particular a roll pallet, is proposed, comprising a container base and two side walls. The side walls are arranged on longitudinally opposite sides of the container base and each comprise a first longitudinal beam and a second longitudinal beam. The first longitudinal beams are each arranged in a first side wall opening of the container base. The second longitudinal beams are each arranged in a second side wall opening of the container base. The first side wall openings are aligned with one another in the longitudinal direction. The second side wall openings are likewise aligned with one another in the longitudinal direction. The first side wall openings are formed in the transverse direction on a side in the container base opposite the second side wall openings.The container base comprises at least one side wall bearing opening into which a longitudinal beam of the further side wall can be inserted for supporting a further side wall on the container base, and the container base has at least one first locking element recess and at least one second locking element recess for receiving a locking element of the further side wall. The first locking element recess is partially or completely aligned in the transverse direction with the second locking element recess. Additionally or alternatively, a bearing strip is releasably fixed to the container base, which bearing strip has at least one bearing strip side wall bearing opening into which a longitudinal beam of the further side wall can be inserted for supporting a further side wall on the container base.

[0006] The core idea of ​​the invention is therefore to provide the container base with a side wall bearing opening and at least two locking element recesses that are at least partially aligned with each other in the transverse direction, and / or to releasably fix a bearing strip to the container base, which comprises a bearing strip side wall bearing opening. A further side wall can thus be easily and securely mounted on the container base.

[0007] The side wall bearing opening and / or the bearing strip side wall bearing opening can correspond to the side wall openings, in particular in their geometry.

[0008] In an exemplary embodiment of the roll container according to the invention, the container base comprises at least one pair of side wall bearing openings. The pair of side wall bearing openings is formed from two side wall bearing openings into which longitudinal beams of the additional side wall can be inserted for supporting another side wall on the container base.

[0009] A first of the sidewall bearing openings of the pair of sidewall bearing openings is aligned, for example, with the first sidewall openings in the longitudinal direction. The second sidewall bearing opening of the pair of sidewall bearing openings is aligned, for example, with the second sidewall openings in the longitudinal direction. The first sidewall bearing opening is, for example, in turn aligned with the second sidewall bearing opening in the transverse direction.

[0010] In a preferred embodiment, the roll container according to the invention comprises at least two, three, four or a plurality of side wall bearing opening pairs.

[0011] The side wall bearing opening pairs are arranged next to one another in the longitudinal direction, for example, in particular at an equal distance from adjacent side wall bearing opening pairs.

[0012] In an exemplary embodiment of the roll container according to the invention, the side wall bearing opening is arranged in the longitudinal direction between the first side wall openings and between the second side wall openings. The side wall bearing opening is offset inwards in the transverse direction relative to the first side wall openings, i.e. in the direction of a longitudinal center plane of the container base or in the direction of the second side wall openings, or offset inwards relative to the second side wall openings, i.e. in the direction of the longitudinal center plane of the container base or in the direction of the first side wall openings, such that when a first longitudinal bar of the further side wall is arranged in the side wall bearing opening, the second longitudinal bar of the further side wall protrudes in the transverse direction on a side of the container base that faces away from the side wall bearing opening.If the sidewall bearing opening is offset inward relative to the first sidewall openings, the second longitudinal beam protrudes laterally at an end of the container base that includes the second sidewall openings. If, however, the sidewall bearing opening is offset inward relative to the second sidewall openings, the second longitudinal beam protrudes laterally in the transverse direction at an end of the container base that includes the first sidewall openings.

[0013] In an exemplary embodiment, the roll container according to the invention comprises two, three, four or a plurality of side wall bearing openings, into which a longitudinal beam of a further side wall can be inserted in order to support further side walls on the container base.

[0014] The sidewall bearing openings can be spaced apart longitudinally. For example, the sidewall bearing openings may not be aligned transversely.

[0015] In a preferred embodiment of the rolling container according to the invention, at least one first side wall bearing opening is provided on the container base, which is offset inward relative to the first side wall openings. Furthermore, at least one second side wall bearing opening is provided on the container base, which is offset inward relative to the second side wall openings.

[0016] The at least one second sidewall bearing opening is offset in the longitudinal direction, for example, from the at least one first sidewall bearing opening, so that they are not aligned with each other in the transverse direction. For example, first sidewall bearing openings and second sidewall bearing openings are provided on the container base, alternating in the longitudinal direction.

[0017] In a preferred embodiment of the rolling container according to the invention, the first locking element recess and / or the second locking element recess are / is funnel-shaped.

[0018] The first locking element recess and / or the second locking element recess can have a geometry corresponding to a quick-release pin of the locking element of the further side wall.

[0019] In an exemplary embodiment of the rolling container according to the invention, a center point of the first locking element recess, preferably the first locking element recess in its entirety, and / or a center point of the second locking element recess, preferably the second locking element recess in its entirety, are / is spaced from a longitudinal center axis of the container base.

[0020] For example, the container base comprises at least two, three, four or a plurality of first locking element recesses and second locking element recesses for receiving locking elements of further side walls to be stored.

[0021] For example, the second locking element recess is offset longitudinally from the first locking element recess. In particular, the locking element recesses are offset from one another in such a way that they are partially, but not completely, aligned with one another. This allows the locking element of the further side wall to be accommodated in different positions, in particular pivoting positions on a cross member of the further side wall.

[0022] For example, the first locking element recess, in particular a center point of the first locking element recess, is aligned in the transverse direction with the side wall bearing opening, in particular a center point of the side wall bearing opening, or a respective one of the side wall bearing openings.

[0023] The second locking element recess or a center point of the second locking element recess can be spaced apart in the longitudinal direction from the side wall bearing opening, in particular a center point of the side wall bearing opening, or a respective one of the side wall bearing openings, i.e. not be aligned therewith in the transverse direction.

[0024] For example, locking elements of the additional side walls to be mounted are each mounted on the cross member of the additional side walls so that they can be displaced in the transverse direction by a defined displacement path. Depending on the position of the locking element relative to the cross member, the locking element can thus be arranged in a first locking element recess or a second locking element recess.

[0025] A distance of the center point of the first locking element recesses from the center point of an adjacent second locking element recess is, for example, less than or equal to the defined displacement path by which the locking element can be displaced on the cross member.

[0026] The locking element recess(es) can be aligned with the side wall bearing opening or a respective one of the side wall bearing openings or with the side wall bearing opening pair or a respective one of the side wall bearing opening pairs in the transverse direction.

[0027] A distance of the locking element recess to the side wall bearing opening in the transverse direction is, for example, at least as large as a minimum distance of the locking element to the longitudinal beam of the further side wall that can be arranged in the side wall bearing opening and at most as large as a maximum distance of the locking element to the longitudinal beam of the further side wall that can be arranged in the side wall bearing opening.

[0028] In an exemplary embodiment of the rolling container according to the invention, the container base has a number of locking element recesses corresponding to the number of side wall bearing openings or the number of side wall bearing opening pairs.

[0029] If the locking element recesses are first locking element recesses and second locking element recesses, the number of first locking elements and the number of second locking element recesses corresponds, for example, to the number of side wall bearing openings or the number of side wall bearing opening pairs.

[0030] An offset of adjacent locking elements in the longitudinal direction corresponds, for example, to the sum of the offset of the first sidewall bearing opening relative to the first sidewall bearing openings in the transverse direction and the offset of the second sidewall of the bearing opening relative to the sidewall bearing openings in the direction of the first sidewall opening in the transverse direction. Thus, if the sidewall bearing openings are formed alternately on opposite sides in the transverse direction, locking elements can be easily inserted into the locking element recesses.

[0031] For example, an offset of the locking elements is less than or equal to a range of movement by which the locking elements are mounted on a cross member of the side walls so that they can be displaced in the transverse direction.

[0032] The centers of the locking element recesses are offset from each other in the longitudinal direction, for example, by a maximum of the defined range of movement of the cross members.

[0033] The locking element recess(es) can have a geometry corresponding to a locking element of the further side wall in such a way that the locking element can be brought into a defined storage position by being inserted into the respective locking element recess.

[0034] For example, the locking element is aligned in the defined storage position such that the locking element has a minimum possible extension in the longitudinal direction.

[0035] The locking element for attaching the additional side wall to a container base is, for example, a drop bracket with a quick-release pin.

[0036] The locking element recess(es) can have a geometry corresponding to the quick release pin of the locking element or a transverse element of the locking element of the further side wall.

[0037] In an exemplary embodiment of the rolling container according to the invention, the bearing strip comprises at least one bearing projection. The bearing projection can be arranged in a bearing strip opening in the container base for positively supporting the bearing strip on the container base.

[0038] For example, the bearing bar comprises two, three or four bearing projections, each of which is arranged in a bearing bar opening of the container bottom for the positive mounting of the bearing bar on the container bottom.

[0039] The bearing projections are spaced apart from each other in the longitudinal direction of the bearing strip, for example.

[0040] The bearing strip may extend transversely, in particular between the two side walls.

[0041] In a preferred embodiment of the rolling container according to the invention, the bearing strip is fixed to the container bottom in such a way that the at least one bearing strip side wall bearing opening is aligned in the longitudinal direction with the first side wall openings or the second side wall openings.

[0042] In an exemplary embodiment, the roll container according to the invention comprises two bearing strips.

[0043] The two bearing strips can be fixed to the container bottom in such a way that the at least one bearing strip wall bearing opening of a first of the bearing strips is aligned in the longitudinal direction with the first side wall openings and the at least one bearing strip side wall bearing opening of the second bearing strip is aligned in the longitudinal direction with the second side wall openings.

[0044] For example, the bearing strips each comprise at least two, three, four or a plurality of bearing strip side wall bearing openings.

[0045] The bearing strips are, for example, fixed to the container bottom in such a way that the bearing strip wall bearing openings of a first of the bearing strips are each aligned in the transverse direction with a respective one of the bearing strip side wall bearing openings of the second bearing strip.

[0046] The vertical extension of the support rails, or their height, is, for example, at least as large as the vertical extension of a section of the longitudinal beams, in particular the outer longitudinal beams, below a lower cross beam. The longitudinal beams of the further side wall can thus be inserted into the support rail wall bearing openings, for example, in such a way that the lower cross beam rests on the support rails.

[0047] The vertical direction extends orthogonally to the longitudinal direction and the transverse direction.

[0048] For example, the bearing strip has a vertical extension such that the locking element of the further side wall is spaced from the container bottom when the further side wall is mounted on the bearing strip. The bearing strip comprises, for example, a gripping area, which is arranged in particular in a central region of the bearing strip in the longitudinal direction of the bearing strip.

[0049] For example, bearing strip side wall bearing openings are formed in the longitudinal direction on both sides of the handle area.

It shows: Fig. 1 is a perspective view of a roll container according to a first embodiment of the invention; Fig. 2 a top view of a container base of the roll container from Fig. 1; Fig. 3 a perspective view of the roll container from Fig. 1 together with other roll containers stored on the roll container; Fig. 4 a top view of the roll container Fig. 1 together with the other roll containers stored on the roll container; Fig. 5 a sectional view along line VV in Fig. 4 through the roll container Fig. 1 together with the other roll containers stored on the roll container; Fig. 6 is a perspective view of a roll container according to a second embodiment of the invention; Fig. 7 a plan view of a container base of the roll container from Fig. 6; Fig. 8 a perspective view of the roll container from Fig. 6 together with additional side walls stored on the roll container; Fig. 9 a top view of the roll container Fig. 6 together with the additional side walls mounted on the roll container; Fig. 10 a bottom view of the roll container from Fig. 6 together with the additional side walls mounted on the roll container; Fig. 11 a perspective view of a roll container according to a third embodiment of the invention before mounting bearing strips of the roll container; Fig. 12 a Fig. 11 corresponding view, during assembly of the bearing strips; Fig. 13 a Fig. 11 corresponding view with mounted bearing strips; Fig. 14 a Fig. 13 corresponding view together with additional side walls mounted on the roll container; Fig. 15 a sectional view along line XV-XV in Fig. 14 through the roll container Fig. 14 together with the other side walls; Fig. 16 a perspective view of the bearing bar; and Fig. 17 another perspective view of the bearing bar.

[0051] In the Fig. 1 and 3 to 5, a roll container 1 according to a first embodiment of the invention is shown. Fig. 3 to 5 show the roll container together with additional side walls and / or additional base containers, which are mounted on the roll container 1. In Fig. 2 shows a container base 2 of the roll container 1 in a standalone view.

[0052] The roll container 1 comprises the container base 2 and two side walls 3. The side walls 3 are arranged on opposite sides of the container base 2 in the longitudinal direction x. To fix the side walls 3 to the container base 2, the container base 2 comprises a first side wall opening 7 and a second side wall opening 8 at opposite end regions in the longitudinal direction x. The first side wall opening 7 and the second side wall opening 8 are provided at opposite ends of the container base 2 in the transverse direction y.

[0053] The side walls 3 each have two longitudinal beams 4 and 5, which delimit the side walls 3 in the transverse direction y. The longitudinal beams 4 are each inserted into a respective one of the first side wall openings 7, and the longitudinal beams 5 are each inserted into a respective one of the second side wall openings 8. The side walls 3 are releasably fixed to the container base 2 by means of a locking element 6, so that removal of the side walls 3 from the side wall openings 7 and 8 is impossible when the locking element 6 is in a secured position in which a transverse element 15 engages underneath the locking element 6. To release the locking elements 6 from the secured position, the locking elements 6 each comprise a quick-release pin 14. The quick-release pin 14 extends in particular orthogonally to the transverse element 15 and, in the secured position of the locking element 6, protrudes upward in the vertical direction z from a transverse beam of the respective side wall 3.

[0054] As from Fig. 2, the base container 2 comprises side wall bearing openings 9 and 10. First side wall bearing openings 9 of the side wall bearing openings 9 and 10 are formed in a first edge region of the container base 2 in the transverse direction y and are aligned in the longitudinal direction x with the first side wall openings 7. Second side wall bearing openings 10 of the side wall bearing openings 9 and 10 are formed in a second edge region of the container base 2 opposite the first edge region in the transverse direction y. The second side wall bearing openings 10 are aligned in the longitudinal direction x with the second side wall openings 8. In the transverse direction y, the first side wall bearing openings 9 are each aligned with a respective one of the second side wall bearing openings 10 and form a side wall bearing opening pair with this. In order to support further side walls 12 on the container base 2, the further side walls 12, in particular longitudinal beams thereof, can each be introduced into a side wall bearing opening pair.

[0055] The first side wall bearing opening 9 and the second side wall bearing opening 10 have geometries corresponding to the first side wall opening 7 and the second side wall opening 8.

[0056] Between the side wall bearing opening pairs, two locking element recesses 11 are formed in the container bottom 2, which are aligned with the side wall bearing opening pair in the transverse direction y.

[0057] The locking elements 6 are mounted on the cross members so that they can be displaced in the transverse direction y by a defined displacement path. The locking element recesses are arranged on the container base 2 in such a way that locking elements 6 of the further side walls 12 can be inserted into both locking element recesses 11 arranged between the locking element pairs.

[0058] As from Fig. 5, locking elements 6 of adjacent further side walls 12 are each arranged in particular in locking element recesses 11 which are offset from one another in the transverse direction y. This means that if a locking element 6 of a first further side wall 12 is arranged in a locking element recess 11 which faces the first side wall bearing opening 9, a locking element 6 of a further side wall 12, which is mounted in an adjacent pair of side wall bearing openings, is arranged in a locking element recess 11 which faces the second side wall bearing openings 10 or the second edge region.

[0059] The locking element recesses 11 have a geometry corresponding to the locking elements 6, in particular the quick-release pins 14 of the locking elements 6. Thus, when inserted into a locking element recess 11, the locking elements 6 are mounted in a defined position, in particular such that the quick-release pin 14 extends in the vertical direction z, or vertically. The transverse element 15 preferably extends in the longitudinal direction x, i.e., horizontally.

[0060] In the Fig. 6 and 8 to 10, a roll container 16 according to a second embodiment of the invention is shown. The roll container 16 according to the second embodiment essentially corresponds to the one described above and shown in the Fig. 1 to 5 according to the first embodiment. Therefore, only the distinguishing features will be explained below. Otherwise, the above embodiments apply accordingly. Identical elements are identified by the same reference numerals in the figures.

[0061] As can be seen in particular from the sole representation of a container base 17 of the rolling container 16 in Fig. 7, the container base 17 comprises side wall bearing openings 18 and 19. First side wall bearing openings 18 of these are arranged in a first edge region in the transverse direction y such that the first side wall bearing openings 18 are offset inwards in the transverse direction y with respect to the first side wall openings 7, i.e. in the direction of the second side wall openings 8, or in the direction of a container base longitudinal center plane. The second side wall bearing openings 19 are provided in a second edge region opposite in the transverse direction y. The second side wall bearing openings 19 are offset inwards in the transverse direction y with respect to the second side wall openings 8 in the direction of the container base longitudinal center plane. The first side wall bearing openings 18 and the second side wall bearing openings 19 are each formed alternately on the container base 2 in the longitudinal direction x.When projecting the first side wall bearing openings 18 in the transverse direction y, a respective one of the second side wall bearing openings 19 is arranged between the first side wall bearing openings 18.

[0062] As can be seen from the Fig. 8 to 10, further side walls 12, which are mounted on the container bottom 17, thus, when arranged in the side wall bearing openings 18 and 19, protrude alternately laterally on opposite sides of the container bottom 2 in the transverse direction y.

[0063] The container base 17 comprises locking element recesses 20. In particular, the container base 17 comprises a first row of locking element recesses 20, which extends in the longitudinal direction x, and a second row of locking element recesses 20 adjacent to the first row in the transverse direction y. The rows are slightly inclined in their extension in the longitudinal direction x in the direction of a transverse center plane in the transverse direction y and are designed, in particular, to be mirror-symmetrical to a diagonal of the base container 17. The locking element recesses have a rectangular or square profile or the shape of a parallelogram in a plan view.

[0064] The locking elements 6 of the further side walls 12 are arranged in a locking element recess 20 of the first row or a locking element recess 20 of the second row, depending on whether the further side walls 12 are arranged in the first side wall bearing openings 18 or in the second side wall bearing openings 19. This means that all further side walls 12 arranged in the first side wall bearing openings 18 are arranged in the locking element recesses 20 of the first row, which faces the second side wall openings 8, and all locking elements 6 of the further side walls 12 that are mounted in the second side wall bearing openings 19 are arranged in locking element recesses 20 of the second row facing the first side wall openings 7.

[0065] As from Fig. 10, the container bottom 17 comprises a reinforcing structure which extends in particular diagonally and is fixed to an underside of the container bottom 17.

[0066] The Fig. 11 to 15 show a roll container 22 according to a third embodiment of the invention. The roll container 22 according to the third embodiment essentially corresponds to the one described above and shown in the Fig. 1 to 5 according to the first embodiment. Therefore, only the distinguishing features will be explained below. Otherwise, the above embodiments apply accordingly. Identical elements are identified by the same reference numerals in the figures.

[0067] The roll container 22 comprises a container base 23, which comprises two bearing bar openings 24 on opposite sides in the transverse direction y. It is also conceivable to provide only one bearing bar opening or more than two bearing bar openings 24 on the container base 23.

[0068] The roll container 22 comprises two bearing strips 25 and 26, which are Fig. 16 and Fig. 17 are shown in isolation. The bearing strips 25 and 26 each have two bearing projections 29, which correspond to the bearing strip openings 24. For supporting additional side walls 12 on the container base 23, the bearing strips 25 and 26 are arranged on the container base 23 such that the bearing projections 29 are each arranged in the respective ones of the bearing strip openings 24. The bearing strips 25 and 26 each extend in the longitudinal direction x and are arranged on opposite sides of the container base 23 in the transverse direction y.

[0069] The bearing strips 25 and 26 each comprise bearing strip side wall bearing openings 28. The bearing strip 25 is arranged on the container base 23 such that the bearing strip side wall bearing openings 28 thereof are aligned with the first side wall openings 7 in the longitudinal direction x. The bearing strip 26 is mounted on the container base 23 such that the bearing strip side wall bearing openings 28 thereof are aligned with the second side wall openings 8 in the longitudinal direction x. In the transverse direction y, the bearing strip wall bearing openings 28 of the first bearing strip 25 are each aligned with a corresponding bearing strip wall bearing opening 28 of the bearing strip 26. To support the further side walls 12 on the container base 23, longitudinal beams of the side walls are each introduced into bearing strip wall bearing openings 28 that are aligned with one another in the transverse direction y.

[0070] The bearing strips 25 and 26 have an extension in the vertical direction z such that the locking elements 6 of the further side walls 12, when the further side walls 12 are introduced into the bearing strip side wall bearing openings 28, are at least slightly spaced from the container bottom 23 and thus hang freely on cross members of the further side walls 12.

[0071] For easy assembly and disassembly of the bearing strips 25 and 26, these each comprise a handle element 27. The handle element 27 can in particular be arranged between two areas comprising the bearing strip side wall bearing openings 28.
