Description

The invention relates to a container for goods transport, in particular a transport container or roll-off container, having a container bottom assembly, two side walls, an end wall and a rear wall, wherein container bottom assembly, side walls, end wall and rear wall form a cargo space, according to the preamble of claim 1.A container, for example in the form of a roll-off container, is a standardized, large steel container or cargo container, which can be rolled onto and off a vehicle via a hook system. It serves primarily for the transport and storage of bulk goods, waste or materials such as round wood, free-flowing or dust-like goods or palletized piece goods, and is used in industry, construction and municipal disposal establishments.A special rolling-off vehicle with hook arm lifts the container on the hook receptacle. The container is pulled or unrolled via its runners (guide rails) onto the load surface. On the rear side there are rollers which make it possible to easily pull on and roll off. The load is secured by side parts, tailgates, lashings or tarpaulins.ACTS (roll-off container transport system) is an intermodal logistics approach in which special roll-off containers can be changed between truck and track without a crane. The containers have ACTS rollers (rotatable rollers on the longitudinal sides) in addition to the standard rollers. On special railway cars or terminals there is a turntable on which the container can be rotated and displaced laterally. A truck rolls the container onto the platform and by rotation it is transferred to the track truck (and vice versa).Conventional roll-off containers are adapted to only a single type of load. For example, roll-off containers for round wood with lateral ridges exist, with which round wood is supplied to a sawwork via, for example, a rail or road connection. The sawwork processes the supplied round wood, but due to the system itself does not dispatch round wood. This has the result that the roll-off containers which have supplied the round wood and are suitable only for this purpose have to be moved back again empty to a loading location for round wood by railway or truck. Conversely, the sawwork produces wood chips to be transported away from the sawwork. For this purpose, other rolling containers, which are adapted to transport wood chips with a closed load space, must first be transported empty to the saw mill by track or truck. These empty drives are cost-intensive logistics and, due to corresponding energy consumption, they burden the environment without immediate use.Each type of goods transport by means of containers requires information about which weight of goods is contained in the containers. This is necessary, on the one hand, to calculate transport costs and, on the other hand, to meet permissible specifications for load weights on the track or truck. One approach to this is external balances which weigh the container before and after loading, it being possible for the containers to be loaded onto trucks or railroad cars only after loading and weighing. This is impractical because in any case the container must be separated from the truck for weight determination, even if this were not necessary for loading or unloading. Moreover, a precisely horizontal surface must be present for such a scale, since the weight measurement by means of conventional scales supplies correct values only when the container is precisely horizontally oriented.EP 1 983 314 A2 discloses an on-board balance for trucks which are equipped for transporting roll containers. Special load corners are composed of a load carrier, a base frame, a load cell and guide plates. Four or more of these load corners together with the weight display and the calibration box form the actual balance. Transverse forces and force shuntings are absorbed by the link plates. The load corners are screwed fixedly to a main frame or auxiliary frame of a truck. The roll container always rests on the load corners even during travel. However, this system has the disadvantage that only trucks specially equipped with these load corners can determine the weight of the roll-off container.EP 2 311 757 B1 discloses a container for the weather-protected transport of free-flowing or dust-like goods or palletized piece goods in combined traffic on rails, ships and roads with a side door. This container has the following structure, which has a rectangular parallelepipedal steel frame structure having two floor longitudinal beams and which carries a container floor, a container roof, two side walls and two end walls. The one side wall is closed and fixed. The other side wall is formed with two pivoting doors, each with at least two door leaves pivotable in the same direction and outwards for opening. However, this container is exclusively suitable for transporting bulk materials or palletized piece materials, that is to say also in particular for wood chips, but not for transporting round wood.The invention is based on the object of expanding a container with respect to the transportable goods. The invention is based on the further object of providing a weighing radio for a container.This object is achieved according to the invention by containers of the above-mentioned type. The invention is solved by the features characterized in claim 1. Advantageous embodiments of the invention are described in the further claims.For this purpose, it is the case in a container of the above-mentioned type. According to the invention, it is provided that the side walls each have a front side wall segment and a rear side wall segment, which form an opening in the side wall between them, wherein at least one door leaf is provided, which is pivotably connected to one of the side wall segments via a hinge, wherein the at least one door leaf is formed in such a way that, in a closed position, it closes the opening between the side wall segments, so that a continuously closed side wall results, and, in an open position, bears against the associated side wall segment and is aligned substantially parallel to the associated side wall segment, so that the opening between the side wall segments is open, wherein the transition from the open position into the closed position takes place by pivoting the at least one door leaf relative to the associated side wall segment, wherein the hinge is formed in each case with at least three pivot axes spaced apart from one another for the pivoting movement between the door leaf and the associated side wall segment, wherein a stanchion for cargo securing is arranged and formed on each side wall adjacent to a free end of the front side wall segment facing away from the front wall and adjacent to a free end of the rear side wall segment facing away from the rear wall in such a way that the door leaf abuts at least one stanchion with an outer side facing away from the cargo space in the closed state.This has the advantage that the container according to the invention can be used in two different configurations, namely a configuration for bulk goods in which the side walls are closed in the circumferential direction and a configuration for round timber in which the side walls have an opening for engaging a loading / unloading device for round timber, such as a fork lift truck or gripper.In a preferred embodiment, the container is a roll-off container, in particular for combined rail / road traffic, in particular with an ACTS system, wherein the container base assembly has a base plate, wherein the front wall has a hook receptacle and wherein the rear wall has a rear wall flap.A particularly simple and thus quick conversion of the container between the open side wall and the closed side wall is achieved in that two door leaves are provided on each side wall, wherein one of the door leaves is connected to the front side wall segment via a hinge at the end of the front side wall segment facing away from the front wall, and wherein the other door leaf is connected to the rear side wall segment via a hinge at the end of the rear side wall segment facing away from the rear wall, wherein the two door leaves are designed such that together in the closed position they close the opening between the side wall segments, wherein in the open position one door leaf bears against the front side wall segment and the other door leaf bears against the rear side wall segment and is in each case aligned substantially parallel to the associated side wall segment.A particularly good adaptation of the contact of the door leaves with the uprights is achieved in that each hinge has at least two, in particular four, segments in the longitudinal direction of the pivot axes, which are pivotable independently of one another.A stable closed side wall without gaps in the region of the base plate in the closed position of the door leaves and a simple load and unloadability of round wood in the open position of the door leaves are achieved in that, for each door leaf, a load beam, the length of which substantially corresponds to the length of the associated door leaf, is arranged on a base plate of the container base assembly pivotably between a first position and a second position, wherein the pivot joint for each load beam is arranged adjacent to a stanchion, such that, in the first position of the load beam, said load beam forms a stop for the door leaf and a closure of a distance between door leaf and base plate in the closed position, and in that, in the second position of the load beam, said load beam forms a support for round wood, such that a lowermost layer of round wood is spaced apart from the base plate.A container which can be particularly well adapted to the selective transport of bulk materials or round wood is achieved in that, in the first position, the loading beams are aligned parallel to the associated side wall and, in the second position, the loading beams are aligned perpendicular to the associated side wall and at least partially overlap the base plate in the direction parallel to the end wall, so that, in the second position, the loading beams of two opposite side walls form at least two supports for round wood which each extend over an entire width of the base plate from side wall to side wall and which are spaced apart from one another in the direction parallel to the side walls.A particularly simple and functionally reliable changeover or pivoting of the loading beams between the first and the second position is achieved in that the pivot joint for the loading beam is in each case formed with a link guide, wherein the link guide is formed in such a way that the respective loading beam latches in the first position and the second position and is lifted from the base plate in any position therebetween, wherein the link guide has oblique flanks in such a way that from a position of the respective loading beam between the first and the second position the force of gravity pivots the respective loading beam into the first or the second position until latching, depending on which of the two positions is closer to the current position of the respective loading beam.In a preferred embodiment of the container according to the invention, at least one rotatable roller is arranged on the container base assembly in the region of an end of the container base assembly on the rear wall side on a side of the container base assembly facing away from the loading space, wherein at least one stand is arranged on the container base assembly in the region of an end wall side of the container base assembly on a side of the container base assembly facing away from the loading space, wherein the at least one roller and the at least one stand are arranged and configured such that they form the single support points of the container such that, in a storage state of the container on a storage plane below the container, an overall force flow from the container into the storage plane takes place via the at least one roller and the at least one stand, wherein the at least one roller and the at least one foot are each connected to the container base assembly via a carrier, wherein each of the carriers is designed and arranged such that, in the storage state of the container, each of the carriers is subject to an elastic deformation, wherein the container has a device for determining a weight of the container, wherein the device for determining a weight of the container has a number of measurement sensors corresponding to the number of carriers for measuring an elastic deformation of a component connected to the measurement sensor compared to an unloaded state of the component, wherein one of the measurement sensors is arranged on each carrier.This has the advantage that a weight of the container can be determined from the measurement of the elastic deformation of the carriers without a classic external weighing device being necessary for this purpose. In contrast to a classic balance, the weight determination does not require a uniform load distribution in the load space and it is likewise not necessary for the weight determination that the container with its container base assembly is aligned exactly perpendicular to a direction of gravity.A particularly accurate measurement of an elastic deformation of the carriers is achieved in that each carrier is designed as a rectangular profile with a longitudinal axis, wherein each carrier is arranged on the container base assembly in such a way that the longitudinal axis encloses a predetermined angle with respect to a plane of the container base assembly with a value greater than 0 degrees and less than 90 degrees.A particularly good measurement of the elastic deformation due to a high amplitude of the elastic deformation with a correspondingly high accuracy and good repeatability of measurement results is achieved in that the measurement sensor is arranged on a side of the carrier which faces the container base assembly or faces away from the container base assembly.A particularly simple and reliable measurement of the weight of the container is achieved in that the measurement sensors are designed and arranged in such a way that they determine a length change of the carrier in the region of the measurement sensor on account of the elastic deformation of the carrier and emit a measurement signal corresponding to the length change.A simple and rapid determination of the weight of the container from data or signals of the measurement sensors is achieved in that the device for determining a weight of the container has a data processing device which determines a weight of the container from data or signals of the measurement sensors and a calibration curve determined for each measurement sensor, which calibration curve assigns a weight to respective data or signals of a measurement sensor.An extension of the container with characteristic data individual for each container, which can be managed individually for the container, for example, via an app on a smartphone, is achieved in that the device for determining a weight of the container has a data management device which stores characteristic data of the container, wherein a transmitting and receiving device, in particular a mobile radio module, is provided which transmits and / or receives the characteristic data of the container.An exact tracking of, in particular, the load, state, location and / or history of the container up to a use calculation by an owner of the container to users who have left the container for transporting goods is achieved by the characteristic data of the container being at least one of the following data, a current GPS position of the container, a current weight of the container, a weight of the container stored over time, a description of the load of the container, a configuration state of the container, a departure location of the container, a destination location of the container, a current speed of the container, a speed of the container stored over time, a serial number of the container, damage to the container, a time period or date for a next maintenance of the container, acceleration data of the container stored over time, a distance travelled by the container, time and / or locally restricted releases for a lock on the container, data about the current user of the container, data stored over time of users of the container and / or data about the owner of the container.A particularly stable and functionally reliable weighing function for the roll-off container is achieved in that the container base assembly has at least two container base assembly cross members and at least two container base assembly longitudinal members on which the base plate rests, wherein at least one of the members is arranged on a container base assembly cross member of the container base assembly, on a container base assembly longitudinal member of the container base assembly or on the base plate of the container base assembly.The invention is explained in more detail below with reference to the drawings. These show in FIG. 1 shows a preferred embodiment of a container according to the invention, by way of example, in the form of a rolling container, in a perspective view from above; FIG. 2 shows the preferred embodiment of the container according to the invention according to FIG. 1 in a perspective view from below; FIG. 3 shows a rotatable roller of the preferred embodiment of the container according to the invention according to FIG. 1 in a perspective view; FIG. 4 shows a stand of the preferred embodiment of the container according to the invention according to FIG. 1 in a perspective view; FIG. 5 shows a door leaf of a side door of the preferred embodiment of the container according to the invention according to FIG. 1 in a closed position for use of the container according to the invention for bulk material in a schematic sectional view along line I-I of FIG. 1 ; FIG. 6 shows a door leaf of a side door of the preferred embodiment of the container according to the invention according to FIG. 1 in a closed position for use of the container according to the invention for bulk material in a schematic sectional view along line II-II of FIG. 1 ; FIG. 7 shows a door leaf of a side door of the preferred embodiment of the container according to the invention according to FIG. 1 in an open position for use of the container according to the invention for round timber in a schematic view from above; FIG. 8 shows the preferred embodiment of the container according to the invention according to FIG. 1, wherein loading beams are arranged in a position as a stop for door leaves of a side door, in a perspective view; FIG. 9 shows the preferred embodiment of the container according to the invention according to FIG. 1, wherein loading beams are arranged in a position as supports for round timber, in a perspective view; FIG. 10 shows a pivoting mechanism for loading beams in a perspective detailed view; and FIG. 11 shows a hinge arrangement for a door leaf of a side door of the preferred embodiment of the container according to the invention according to FIG. 1 in a perspective detailed view.Although the invention is described below with reference to a roll-off container, the invention is not limited to roll-off containers, but can be applied to any type of container or transport containers with a bottom, side walls, front wall and rear wall, which form a store space.The container according to the invention, which is illustrated as an example as a roll-off container in FIGS. 1 and 2, has the following: a container bottom assembly with a base plate 10, container bottom assembly cross member 12 and container bottom assembly longitudinal member 14, two side walls 16, an end wall 18 with a hook receptacle 20 and a rear wall 22 with a rear wall flap 24. In the embodiment shown, the roll-off container does not have a roof on the top side which delimits the cargo space at the top. However, this is merely optional; a corresponding roof can also be provided.The end wall 18 is composed of an end wall plate 181 and end wall longitudinal beams 182 and end wall transverse beams 183. The entire structure for the hook receptacle 20 is fastened to the front wall longitudinal members 182 and the front wall transverse members 183.The side walls 16 were each composed of a front side wall segment 161 and a rear side wall segment 162 forming an opening therebetween. In this opening, two door leaves 163 are arranged, which can be pivoted inward in the direction of the cargo space. In the state illustrated in FIGS. 1 and 2, the door leaves 163 are closed, resulting in a continuously closed cargo space for bulk material of any type. On the base plate 10 there is provided for each door leaf 163 a loading beam 26 whose length corresponds substantially to the length of the associated door leaf. The loading beams 26 are pivotable via a hinge in a plane parallel to the base plate 10, which will be explained in detail later. In the position of the loading beams 26 shown in FIGS. 1 and 2, these beams each form a stop for one of the door leaves 163. In this way, a gap between door leaf 163 and base plate 10 is closed, so that no bulk material can escape from the cargo space here. Furthermore, the loading beams 26 support the door leaves 163 on their underside, which faces the base plate 10, against forces acting outwards on the door leaves 163 by the item to be loaded. In this respect, the loading beams 163 form a completion of a tension belt running in the vicinity of the base plate 10 against outwardly acting forces of the load.The door leaves 163 are each pivotably connected via a hinge 28 to the front side wall segment 161 at its free end 76 remote from the end wall 18 or to the rear side wall segment 162 at its free end 78 remote from the rear wall 22. In the region of the hinge articulation between the side wall segments 161, 162 and the respectively associated door leaves 163, a stanchion 30 is arranged in each case, which is anchored in the container base assembly and extends upwards in the direction of the cargo space starting from the base plate 10. These posts 30 serve as load securing means during the transport of round wood or also bulk material by means of the roll-off container according to the invention and as supports against which the door leaves 163 abut in the closed state. Corresponding to the number of hinges 28 for connecting the door leaves 163 to the side wall segments 161, 162, four ridges 30 are provided. As is customary for transporting round timber, these posts 30 are inclined in the direction of the cargo space, so that they only bend outwards under the load of the loading by round timber into a position in which they are aligned substantially completely perpendicular to the floor panel 10.The roll container according to the invention further comprises fork lift truck pockets 32 which serve for the introduction of fork prongs of a fork lift truck in order to lift the entire roll container and, if appropriate, to tilt it for unloading the cargo.On the underside of the roll-off container, two rotatable rollers 34 are arranged in a region of an end of the container base assembly on the rear wall side and on a side of the container base assembly facing away from the cargo space. Furthermore, two feet 36 are arranged on the underside of the roll-off container in a region of an end wall-side end of the container base assembly and on a side of the container base assembly facing away from the loading space. The rotatable rollers 34 and the feet 36 are arranged and configured in such a way that in a storage state of the roll container, in which the roll container is standing or is stored on a plane, the roll container is supported only on the rollers 34 and the feet 36. In this way, a total force flow occurring due to the force of gravity runs from the roll container to the plane beneath it exclusively via the rollers 34 and the feet 36.As can be seen from FIGS. 3 and 4, the rollers 34 and the feet 36 are connected in a positively locking manner to the container base assembly via carriers 38, wherein the feet 36 are connected in an articulated manner to an end of a respective carrier 38 facing away from the container base assembly. The articulated feet 36 have identical ground irregularities. In the illustrated embodiment, the beams 38 are each secured to one of the container bottom assembly cross-beams 12. The carriers 38 are designed as box profiles and a longitudinal axis 42 of the carriers 38 encloses a predetermined angle 40 with a plane 44 of the base plate 10. In the embodiment shown, this angle 40 is, for example, 30 degrees. All the carriers 38 are thus subjected to elastic deformation in the storage state of the container, in which the entire force flow flows via the rollers 34 and the feet 36.According to the invention, it is now provided to use this elastic deformation to determine a weight of the roll container. For this purpose, a sensor 46 is arranged on each carrier 38. Each sensor 46 measures its elastic deformation on the carrier 38 assigned to it due to the weight force of the container in comparison to a zero position of the carrier 38 not elastically deformed without application of force. A weight at this location is then determined from a calibration curve for each pair of support 38 and sensor 46. The total weight of the roll container is then obtained from the sum of all weights determined by all sensors 46 present. In the embodiment shown with two rollers 34 and two feet 36, to which a total of four sensors 46 are assigned, a 4-point bending system is thus integrated on the roll container. Preferably, the sensors 46 only supply a sensor signal that is dependent on the strength of the elastic deformation of the associated carrier 38 starting from or relative to a zero position in which the carrier 38 is not acted upon by force and is therefore not elastically deformed. The sensor signals of all sensors 46 are then processed in a data processing unit (not shown) and used to calculate the total weight of the roll container.For the highest possible accuracy of the measurement, in the embodiment shown, the sensors 46 are arranged on a surface 381 of the carrier 38 which faces the plane 44 of the base plate 10. At this surface 381, the elastic deformation of the carrier 38 leads to a change in length between corresponding ends of the sensor 46, such that the sensor 46 can determine the elastic deformation of the carrier 38 indirectly via this change in length. A characteristic measurement length L 0 of the sensor 46 is, for example, 150 mm. A rated load per sensor 46 is, for example, 60.7 kN (force which acts on one of four measurement points or sensors in f= 1,5 taking into account the dead weight, payload and load factor L). A permissible technical elongation for the carrier 38 is, for example, up to 1000 μm / m. A value for the ratio of length change.DELTA.L to measurement length L 0( .DELTA.L / L 0) is, for example, 149 μm / m. In this case, .DELTA.L denotes a reactive length change over the characteristic measurement length L 0 of the sensor 46 and is, for example, 0.02237 mm. The characteristic measurement length L 0 of the sensor 46 is the length L 0 without load. A total load to be measured is, for example, m g= 16,5 t (mass) or F g= 161,9 N (weight force).The weighing system or the device for determining a weight of the roll container has, for example, a data processing device 74 (FIG. 1 ), which is attached to the roll container, for example to the end wall 18, and which determines a weight of the roll container from the data or signals of the measurement sensors 46 and a calibration curve determined for each measurement sensor 46, which calibration curve assigns a weight to respective data or signals of a measurement sensor 46. Alternatively, the data or signals of the measurement sensors 46 are transmitted as raw data and further processed in an external data signal processing. As a result, the data can be stored in a cloud and are available to different users and authorized persons.The weighing system or the device for determining a weight of the roll-off container, which is integrated into the roll-off container, can optionally be provided with further additional utility. These additional users are integrated, for example, in a data management device 70 (FIG. 1 ) with a mobile radio module 74 (FIG. 1 ), which is attached to the roll container according to the invention, for example to the end wall 18, and relate, for example, to the acquisition, storage and provision of further characteristic data individually for each roll container, such as, for example, a current GPS position of the roll container, a current weight of the roll container, a weight of the roll container stored over time, a description of the load of the roll container, a configuration state of the roll container (configuration for round wood or bulk material), a departure location of the roll container, a destination location of the roll container, a current speed of the roll container, a speed of the roll container stored over time, a serial number of the roll container, damage to the roll container, a time period or date for a next maintenance of the roll container, acceleration data of the roll container stored over time, a distance travelled by the roll container, time- and / or locally-restricted releases for a lock on the roll container, data on the current user of the roll container, data stored over time of users of the roll container and / or data on the owner of the roll container. By further supplementing the weighing system with a mobile radio module, it is additionally possible to manage these stored data. These include both the input of these data into the weighing system and the retrieval of the currently stored characteristic, individual data for a roll container from the weighing system. This can be realized, for example, via an app on a smartphone of the user of the roll container.As can be seen from FIGS. 5 to 7, the door leaves 163 are pivotably arranged via the hinges 28 on the front side wall segment 161 or on the rear side wall segment 162 in such a way that the door leaves 163 can be pivoted inward in the direction of the cargo space relative to the side wall segments 161, 162. The swivel angle is 180°. In this way, the door leaves 163 can be pivoted inward to such an extent that they bear against the inner sides of the front side wall segment 161 and of the rear side wall segment 162, respectively. This state is shown in FIG. 7. It is obvious that the section of the side wall 16 between the front side wall segment 161 and the rear side wall segment 162 is hereby opened, so that in this area, where the door leaves 163 previously completed the side walls 16, the side walls 16 are open towards the cargo space. In this way, a configuration of the roll-off container according to the invention is produced in which the roll-off container can be used for transporting round wood.To complete this configuration (round timber configuration), the loading beams 26 are furthermore pivoted from the position shown in FIG. 8 by 90° about a respective joint 48 into a position shown in FIG. 9, so that two opposite loading beams 26 form a support for round timber extending over the entire width of the base plate 10. In this way, the lowermost layer of round wood is spaced apart from the base plate and a free space is formed in which the fork of a forklift can engage for receiving or depositing the round wood from or into the roll-off container.The position of the loading beams 26 shown in FIG. 8 corresponds to a bulk material configuration of the roll-off container according to the invention, in which the loading beams 26 have the function of a stop for the door leaves 163 and thus close a gap between the door leaves 163 and the base plate 10.The position of the loading beams 26 shown in FIG. 9 corresponds to a round timber configuration of the roll-off container according to the invention, in which the loading beams 26 have the function of a support for a lowermost layer of round timber, such that the lowermost layer of round timber does not bear directly on the base plate 10.The configuration of the joint 48 is shown in FIG. 10. The joint 48 has a slotted guide 50, in which the respective loading beam 26 engages in the position according to FIG. 8 (first position of the loading beams or bulk material configuration) and in the position according to FIG. 9 (second position of the loading beams or round timber configuration). Between these two positions, the slotted guide 50 ensures that the loading beam 26 is lifted somewhat from the base plate 10, so that it is not necessary for the pivoting of the loading beams 26 to overcome a frictional force between an entire length of the loading beam 26 and the base plate 10. In this way, the pivoting of the loading beams 26 from one position or configuration into the other position or from the first position into the second position and vice versa is simplified and can be carried out significantly more quickly. The respective positions for the configurations are clearly defined. At the same time, the latching function of the slotted guide 50 ensures that the loading beams 26 are only either in one position or in the other, but not in an intermediate position, since the slotted guide 50 alone by the action of gravity results in either the one or the other end position or position of the loading beams 26 being taken up. For this purpose, corresponding oblique flanks are provided in the slotted guide.In FIGS. 8 and 9, the side walls 16 and the rear wall 22 are not shown merely for the sake of better clarity of the illustration. For the round timber configuration shown in FIG. 9, the front side wall segments 161, the rear side wall segments 162 and the door leaves 163 (in the configuration according to FIG. 7 ) and the rear wall 22 are naturally present and do not have to be dismantled.It is also important to note that for changing the configuration of the roll-off container according to the invention from round wood configuration to bulk material configuration or vice versa, the stanchions 30 do not have to be changed in their position.Preferably, the front side wall segments 161 and the rear side wall segments 162 are not firmly welded to the container bottom assembly, but are screwed together. In this way, it is possible, similar to a modular system, to exchange the front and rear side wall segments 161, 162 in order to adapt them to specific requirements of transport goods. Furthermore, these can be replaced easily in the event of possible damage. This avoids the situation with conventional rolling containers, in which these have to be completely scrapped or in which laborious welding operations are necessary if the side walls are damaged.The embodiment of the hinge 28 can be seen from FIGS. 5, 6, 7 and 11. The hinge 28 is shown in detail in FIG. 11, wherein the stanchion 30 is not shown for the sake of better clarity. The hinge 28 is designed in a particular manner, so that the position of the door leaves 163 in the region of the hinges 28 can adapt to the respective state of the stanchion 30. The term "state of the stanchion" here denotes a more or less heavy loading of the stanchion 30 by the cargo in the direction outwards away from the cargo space. The stanchion 30 is designed in such a way that it can flex outwards under a load from the cargo, wherein the lower end 66 of the stanchion 30 facing the base plate 10 is fixed and the stanchion 30 can flex outwards over its entire length in the direction of a free end 68 of the stanchion 30 facing away from the base plate 10. In this case, the local offset due to the bending of the stanchion 30 outwards over the length of the stanchion 30 from the lower end 66 of the stanchion 30 facing the base plate 10 to the free end 68 of the stanchion 30 facing away from the base plate 10 is not constant, but rather is greatest at the free end 68 of the stanchion 30 facing away from the base plate 10 and becomes smaller and smaller in the direction of the lower end 66 of the stanchion 30.In order that the hinge 28 and thus the door leaf 163 can be adapted to this different offset of the stanchion 30 along the length of the stanchion 30, the hinge 28 is formed on the one hand with three pivot axes 52, 54, 56 which are aligned substantially perpendicular to the base plate 10 and on the other hand the hinge 28 is divided along the pivot axes 52, 54, 56 into four segments 58, 60, 62, 64 which can be pivoted relative to the side wall segments 161, 162 and the door leaves 163 to a certain degree independently of one another. In this way, along the pivot axes 52, 54, 56, the segments 58, 60, 62, 64 can assume slightly different pivot angles relative to the side wall segment 161, 162 or the door leaves 163. This is illustrated in FIGS. 5 and 6. FIG. 5 shows the state of the hinge 28 at the upper end near the free end 68 of the stanchion 30 facing away from the base plate 10. Since the stanchion 30 in the unloaded state is inclined slightly inward in the direction of the cargo space, this free end 68 of the stanchion 30 is located somewhat further inward in the direction of the cargo space than the lower end 66 of the stanchion 30 facing the base plate 10. In FIG. 6, on the other hand, the state of the hinge 28 in the vicinity of the base plate 10 is shown. The door leaf 163 must be positioned further outwards away from the cargo space in comparison to the free end 68 of the stanchion 30. This reaches the hinge 28 with the relevant segment 58 by a less elongated, more angled position of the three pivot axes 52, 54, 56. Overall, it is thus possible for the door leaf 163 to assume an oblique position deviating from a position perpendicular to the base plate 10, so that the door leaf 163 can follow the slightly oblique position of the stanchion 30 in the unloaded state. With increasing loading, a corresponding force of the cargo causes the stanchions 30 to be increasingly pushed outwards. In this case, the displacement is greatest due to the outward pressing at the free end 68 of the stanchion 30. Due to the three pivot axes 52, 54, 56 and the segments 58, 60, 62, 64 of the hinge 28, the hinge 28 or the door leaf 163 can follow a stanchion 30 that is pressed further outwards or oriented more upright continuously.Furthermore, the hinge 28 with the three pivot axes 52, 54 and 56 enables each door leaf 163 to perform not only a pivoting movement relative to the associated side wall segment 161, 162 but also a translatory movement relative to the associated side wall segment 161, 162, such that a distance between the associated side wall segment 161, 162 and the door leaf 163 articulated thereto via the hinge 28 can be varied. In this way, it is possible to move the door leaf 163 from the closed position, as shown in FIGS. 1, 2, 5 and 6, to the open position, as shown in FIG. 7, in which the door leaf abuts the associated side wall segment 161.References included in the specificationThis list of documents cited by the applicant has been produced in an automated manner and is only included for the better information of the reader.
