Description

[Technical Field]

[0001] The present invention relates to an openable curtainsider system for multipurpose vehicles such as trucks, semi-trailers, transport vehicles, trailers, containers, railroad freight cars, etc. The present invention further relates to a sliding stanchion for the curtainsider system. [Background technology]

[0002] In fact, a wide variety of solutions and designs are known for curtain-sider systems for utility vehicles. Utility vehicles, such as trucks, trailers and semi-trailers, are primarily used to transport goods and products on public roads. For this reason, utility vehicles include a cargo space provided to accommodate the goods and products to be transported. This cargo space is, for example, equipped with a curtain-sider system on both sides.

[0003] The main task of the curtain-sider system of a utility vehicle is to protect the cargo from rain, dust, weather and other lateral influences. Furthermore, the curtain-sider system must ensure that the cargo is protected, especially when moving, for example when cornering or during emergency braking, so that the curtain-sider system is always able to absorb the defined horizontal forces exerted on it, for example by sliding cargo in the cargo space.

[0004] Furthermore, the curtainsider system should have as low a dead weight as possible so that operational trips are cost-effective and energy-saving. Another important aspect is the rapid opening and closing of the curtainsider system to keep the so-called non-productive time for loading and unloading as short as possible. It is also advantageous for the curtainsider system to be able to provide the largest possible opening to the cargo space so that loading and unloading of goods and products can take place with little hindrance.

[0005] DE 197 56 617 A1 shows an openable curtainsider system for a utility vehicle, which comprises at least one sliding stanchion with a stanchion suspension device displaceable along a first chamber of a longitudinal beam supported against the loading platform, and at least one tarpaulin segment which at least partially closes a side opening of the utility vehicle and is suspended by a tarpaulin suspension device displaceable along a second chamber of the longitudinal beam, wherein the side tarpaulins can be connected to the corner stanchions by keder connections.

[0006] DE 10 2020 126 429 A1 shows a multi-purpose vehicle with an openable curtainsider system, which comprises at least one tarpaulin segment that at least partially closes a side opening of the multi-purpose vehicle, the tarpaulin segment having at least one edge-to-side connecting element that is connected to a corresponding counter element of a corner stanchion. Here, the connecting element of the tarpaulin segment is designed as a keder.

[0007] EP 2 708 395 A1 discloses an openable curtainsider system for a multi-purpose vehicle, such as a semi-trailer, comprising at least one sliding stanchion with a stanchion suspension device displaceable along a longitudinal beam supported on the loading platform. The stanchion suspension device has a total of three horizontal guide rollers and two vertical load-bearing rollers, with two guide rollers located in the lower chamber of the longitudinal beam and a third guide roller located between the two load-bearing rollers in the upper chamber of the longitudinal beam. The system also discloses at least one tarpaulin segment displaceable along the longitudinal beam by the stanchion suspension device, which at least partially closes a side opening of the multi-purpose vehicle. Furthermore, in one area of ​​the loading platform, there is a guide rail that is designed to be approximately identical to the upper longitudinal beam, and the sliding stanchions have at their lower ends sliding stanchion carriages that approximately correspond to the stanchion suspension devices, so that the sliding stanchions can be displaced at their lower ends along the guide rail by the sliding stanchion carriage. The tarpaulin segments are directly connected to the sliding stanchions by fastening devices, so that the tarpaulin segments can follow the displacements of the sliding stanchions in the longitudinal direction of the loading platform.

[0008] DE 10 2016 103 171 A1 shows an openable curtainsider system for a utility vehicle, which comprises at least one sliding stanchion with a stanchion suspension device displaceable along a first chamber of a longitudinal beam supported against the loading platform, and at least one tarpaulin segment which at least partially closes a side opening of the utility vehicle and is suspended by a tarpaulin suspension device displaceable along a second chamber of the longitudinal beam, the stanchion suspension device having two twin load-bearing rollers.

[0009] JP 7-276 990(A) discloses an openable curtainsider system for a utility vehicle, which comprises at least one sliding stanchion having a stanchion suspension device displaceable along a first chamber of a longitudinal beam supported against the loading platform, and at least one tarpaulin segment that at least partially closes a side opening of the utility vehicle and is suspended by a tarpaulin suspension device displaceable along a second chamber of the longitudinal beam, the stanchion suspension device being arranged in the first chamber and in each case having a guide roller in the direction of movement.

[0010] EP 2 835 282 A1 shows a structure for a roof cover frame of a utility vehicle, the structure having a cargo safety device displaceable along the longitudinal direction in a first chamber, the cargo safety device including a carriage having a first pair of twin load-bearing rollers at a first end and a second pair of twin load-bearing rollers at a second end, two guide rollers arranged between the first pair of twin load-bearing rollers and the second pair of twin load-bearing rollers, and a locking device arranged between the two guide rollers.

[0011] WO 2009 003 218(A1) shows an openable curtainsider system for a utility vehicle, with side tarpaulins suspended from tarpaulin suspension devices displaceable along a chamber of a longitudinal beam, where a profile rail is arranged in one area of ​​the loading platform, to which the lower area of ​​the side tarpaulin can be fastened by a tensioning device, and a metal strip is inserted into the pocket of the side tarpaulin between the upper tarpaulin suspension device and the lower tensioning device, the metal strip being connected to the tarpaulin suspension device and the lower tensioning device by a fastening means. The tarpaulin suspension device has a first pair of twin load-bearing rollers and a second pair of twin load-bearing rollers, with two horizontal guide rollers arranged between the two twin load-bearing rollers.

[0012] German Patent Application Publication No. 32 04 505 A1 discloses an openable curtainsider system for a utility vehicle, comprising side tarpaulins suspended from tarpaulin suspension devices displaceable along upper chambers of a longitudinal beam, a guide rail with a lower chamber arranged in one area of ​​the loading platform, a lower area of ​​the side tarpaulins displaceable along the guide rail by a tarpaulin carriage, a reinforcing strip arranged between the upper tarpaulin suspension device and the lower tarpaulin carriage, the reinforcing strip being connected to the tarpaulin suspension device and the lower tarpaulin carriage by fastening means, Furthermore, the tarpaulin suspension device and the lower tarpaulin carriage each have a first pair of twin load-bearing rollers and a second pair of twin load-bearing rollers, and the lower tarpaulin carriage further has at least one horizontal guide roller.

[0013] DE 10 2011 107 377 A1 discloses an openable curtainsider system for a utility vehicle, which comprises at least one height-adjustable sliding stanchion with a stanchion suspension device displaceable along a chamber of a longitudinal beam supported against the loading platform, and at least one tarpaulin segment which at least partially closes a side opening of the utility vehicle and is suspended by a tarpaulin suspension device respectively arranged on the stanchion suspension device, the stanchion suspension device having two twin load-bearing rollers, and a guide roller with a lower chamber is arranged in an area of ​​the loading platform in which the sliding stanchion is displaceable along a guide rail by means of a sliding stanchion carriage.

[0014] DE 10 2017 107 583 A1 discloses a load-bearing roller for the carriage of a roof frame for tarpaulin construction, which has a flange area that is suitable for absorbing horizontal forces.

[0015] DE 10 2016 103 172 A1 discloses a retractable curtainsider system for a utility vehicle, with a side tarpaulin suspended from at least one tarpaulin suspension device, the tarpaulin suspension device having two load-bearing rollers and at least one guide roller, the load-bearing roller being displaceable in a first chamber of a longitudinal beam and the guide roller being displaceable in a second chamber of the longitudinal beam, where the guide roller is arranged between the two load-bearing rollers below the first chamber.

[0016] German Patent Application Publication No. 10 2017 126 055(A1) discloses an openable curtainsider system for utility vehicles. The openable curtainsider system at least partially closes the side opening of the utility vehicle and includes a side tarpaulin suspended by a tarpaulin suspension device displaceable along a longitudinal beam supported against the loading platform. The side tarpaulin has at least one edge-to-side connection element connected to a counter element of the corner stanchion. The side tarpaulin connection element includes a kedder inserted into a kedder rail designed as a counter element of the corner stanchion. The side tarpaulin also has a strap. A drawback of this curtainsider system is that the side tarpaulin can only be moved along the longitudinal beam using the tarpaulin suspension device. The side tarpaulin includes a tension element at its lower horizontal edge that can be engaged with the loading platform. Opening or closing the side tarpaulin therefore always requires that the tensioning elements of the side tarpaulin be operated, which makes opening or closing the side tarpaulin time-consuming. Furthermore, an at least partially open side tarpaulin is not fastened or tensioned at its lower edge, so that the side tarpaulin can be displaced in an uncontrolled manner.

[0017] German Patent Application Publication No. 10 2006 043 655 (A1) discloses an openable curtainsider system for utility vehicles. The curtainsider system includes at least one sliding stanchion with a stanchion suspension device displaceable along a chamber of a longitudinal beam supported on the loading platform. The curtainsider system also includes a side tarpaulin that at least partially closes the side opening of the utility vehicle. The side tarpaulin has a connecting element connected to a counter element of the sliding stanchion. The counter element includes a keder rail with a groove into which the connecting element, designated as a keder, of the side tarpaulin is inserted. Furthermore, the side tarpaulin is attached exclusively to the sliding stanchion. A disadvantage is that the side tarpaulin is attached exclusively to the sliding stanchion or corner stanchion, meaning that almost the entire weight of the side tarpaulin is supported by the sliding stanchion. This type of fastening shortens the service life of the side tarpaulin, which is constantly exposed to high loads. Furthermore, there are problems with sealing against rain, meltwater and sewage in the roof area of ​​the utility vehicle, as the side tarpaulins are not connected to the longitudinal beams. In addition, the side tarpaulins are attached in one area to the pulling edge of the loading platform by means of pulling elements, which makes opening and closing the side tarpaulins time-consuming.

[0018] German Utility Model No. 20 2013 006 707(U1) discloses a tarpaulin for a utility vehicle, which is connected to the roof cover frame of the utility vehicle. The tarpaulin can be used in either a curtainsider system or a roof tarpaulin system for the utility vehicle. The corresponding curtainsider system comprises at least one sliding stanchion displaceable along a longitudinal beam supported against the loading platform. Furthermore, the curtainsider system comprises at least one tarpaulin segment that at least partially closes a side opening of the utility vehicle. The tarpaulin segment has at least one edge-to-side connecting element designed as a keder. The keder of the tarpaulin segment is connected to a counter element of the sliding stanchion, which is designed as a keder rail.

[0019] WO 2017 214 689(A1) describes an openable curtainsider system for a utility vehicle. The curtainsider system includes at least one sliding stanchion with a stanchion suspension device displaceable along a longitudinal beam supported on the loading platform. The curtainsider system also includes a side tarpaulin that at least partially closes the side opening of the utility vehicle. The sliding stanchion also includes a sliding stanchion carriage that can move along a guide rail attached to the loading platform. The side tarpaulin is connected to the sliding stanchion and has an upper edge parallel to the longitudinal beam and a lower edge parallel to the loading platform. The sliding stanchion has a trapezoidal cross-section that facilitates guiding the sliding stanchion over obstacles when opening or closing the side tarpaulin. Furthermore, a folding aid for the side tarpaulin is disposed between adjacent sliding stanchions. The disadvantage is that the curtain-sider system has a continuous side tarpaulin and therefore contains an unnecessarily large number of components, as opposed to, for example, sliding stanchions, which increases the overall weight of the utility vehicle. Furthermore, the manufacture and installation of the curtain-sider system is time-consuming and expensive.

[0020] European Patent Application Publication No. 3 284 624 A1 discloses a sliding stanchion for an openable curtainsider system for a utility vehicle. The sliding stanchion includes a sliding stanchion body having an upper end and a lower end. The upper end of the sliding stanchion body includes a stanchion suspension device having at least two upper load-bearing rollers and at least one upper guide roller disposed between the two load-bearing rollers, the upper load-bearing rollers and the upper guide roller being disposed in a first chamber of a longitudinal beam. The stanchion suspension device is displaceable along the longitudinal beam of the utility vehicle supported on the loading platform, and an additional guide roller is disposed in a second chamber of the longitudinal beam. The sliding stanchion further includes a sliding stanchion carriage disposed at the lower end of the sliding stanchion body, the load-bearing rollers and the guide roller of the sliding stanchion carriage also requiring two chambers. The sliding stanchion carriage includes at least one lower load-bearing roller and at least one lower guide roller. The side tarpaulins of the releasable curtainsider system are attached to the sliding stanchion body of the sliding stanchion. A disadvantage is that the curtainsider system has a continuous side tarpaulin. In this respect, an increase in mechanical point loads on the side tarpaulin can be expected due to its own weight. In particular, in the fastening area within the sliding stanchion, high tensile forces in the direction of movement and the weight of the side tarpaulin in the vertical direction act on the side tarpaulin or the connecting elements during the opening and closing process of the curtainsider system.

[0022] The object of the present invention is to provide an openable curtainsider system and sliding stanchions for utility vehicles that allows the side tarpaulins of the utility vehicles to be opened and closed easily and reliably and that can be manufactured cost-effectively. [Means for solving the problem]

[0023] This object is solved according to the present invention by an openable curtainsider system having the features of independent claim 1 and by a sliding stanchion having the features of independent claim 10.

[0024] According to one aspect of the present invention, there is provided an openable curtainsider system for multipurpose vehicles such as trucks, semi-trailers, transport vehicles, trailers, containers, rail cars, etc. The openable curtainsider system includes at least one sliding stanchion having a stanchion suspension device displaceable along a first chamber of a longitudinal beam supported on the loading platform. The openable curtainsider system further includes at least one tarpaulin segment that at least partially closes a side opening of the multipurpose vehicle and is suspended by a tarpaulin suspension device displaceable along a second chamber of the longitudinal beam. In this regard, the stanchion suspension device has at least two twin load-bearing rollers. The openable curtainsider system is characterized by the stanchion suspension device having a guide roller on the outer side of each of the twin load-bearing rollers arranged in the first chamber in the direction of movement. By providing two twin load-bearing rollers and two guide rollers in the first chamber, the stanchion suspension device not only supports the mass of the sliding stanchion, but also ensures that the forces normally applied to the sliding stanchion and / or the connected tarpaulin segments, whether during loading or the dynamic load of the cargo during movement, are brought to the corresponding longitudinal beam by the load-bearing rollers.

[0025] Preferably, a further twin load-bearing roller can be arranged between at least two twin load-bearing rollers adjacent to the guide roller, for example 1, 2, 3, 4, 5 or 6 twin load-bearing rollers, so that the total number of twin load-bearing rollers is 3, 4, 5, 6, 7 or 8 accordingly. The intervening twin load-bearing rollers increase the axial load-bearing capacity of the sliding stanchion and advantageously prevent the stanchion suspension device from jamming or twisting. Since the stanchion suspension device conveniently runs in the first chamber, there is no risk of the stanchion suspension device colliding with the tarpaulin suspension device. If the stanchion suspension device does not protrude beyond the stanchion body in the direction of tarpaulin movement by more than 1.5 times the width of the tarpaulin suspension device, the overall package of opened side tarpaulins will not increase.

[0026] According to one aspect of the present invention, there is provided a sliding stanchion for an openable curtainsider system for multipurpose vehicles such as trucks, semi-trailers, transport vehicles, trailers, containers, railcars, etc. The sliding stanchion comprises a sliding stanchion body having an upper end and a lower end, the upper end of which has a stanchion suspension device, the stanchion suspension device having at least two upper twin load-bearing rollers and at least one upper guide roller. In this regard, the upper load-bearing roller and the upper guide roller are displaceable in a first chamber of the longitudinal beam. The sliding stanchion is characterized in that the stanchion suspension device has a guide roller on the outer side of each of the twin load-bearing rollers in the direction of movement. The guide roller ensures that the sliding stanchion can be displaced without jamming. Furthermore, the two guide rollers align the sliding stanchion so that the sliding stanchion can always move smoothly and without jamming along the longitudinal beam, even at a slight incline. In particular, the two guide rollers arranged in the forefront in the direction of travel allow the forces normally acting on the sliding stanchion to be absorbed, and the provision of the two guide rollers in an outer position, and therefore at a considerable distance from each other, prevents tipping moments that arise in the case of asymmetrical loads.

[0027] Advantageously, the sliding stanchion has a sliding stanchion carriage at the end opposite the stanchion suspension device, by means of which the stanchion can be displaced relative to a guide rail assigned to the loading platform. It is therefore advantageous for the sliding stanchion to be mounted and guided at its upper part by the stanchion suspension device and at its lower part by the sliding stanchion carriage. Guides at both ends of the sliding stanchion advantageously support its unimpeded displacement. Furthermore, the guides at both ends prevent the sliding stanchion from being pushed out of the guideway of the longitudinal beam or out of the guide rail when horizontal forces act on the sliding stanchion. Advantageously, in that case, the sliding stanchion can also transmit forces normally exerted on the sliding stanchion or the connected tarpaulin segment not only to the longitudinal beam but also to the guide rail, so that the longitudinal beam and the guide rail can jointly absorb such loads. It is no longer necessary to remove the sliding stanchions from the stanchion base and then manually fasten them again. In this way, the entire side tarpaulin can be closed very quickly. Furthermore, the stanchions no longer need to be individually locked to connect them to the stanchion base. There is no longer any risk of the structure being weakened by the sliding stanchions not being fixed to the loading platform.

[0028] Preferably, each sliding stanchion carriage has at least one load-bearing roller arranged above the guide rail and at least one counter roller arranged below the guide rail. The upper and lower support or guide rollers increase the stability and robustness of the sliding stanchion. Furthermore, the sliding stanchion can absorb horizontal forces without being pushed out of the guide rail. In addition, the combination of the load-bearing roller and the guide roller increases the smooth running of the sliding stanchion carriage as it moves along the guide rail, thereby preventing it from getting stuck at all times. The forces normally acting on the sliding stanchion are absorbed, in particular, by the lower counter roller.

[0029] Preferably, the sliding stanchion has a downwardly protruding stop body at the end facing the stanchion suspension device, the stop body being located on the inner side of the sliding stanchion next to the sliding stanchion carriage. The stop body provides additional protection against the lower sliding stanchion carriage being pushed out of the guide rail if a load or obstacle in the inner lower area of ​​the sliding stanchion exerts a force against the sliding stanchion. Furthermore, the stop body provides protection against damage to the sliding stanchion carriage of the sliding stanchion.

[0030] Conveniently, at least one tarpaulin segment has a tarpaulin carriage at its end facing the tarpaulin suspension device, by means of which the tarpaulin segment can be displaced relative to a guide rail assigned to the loading platform. Advantageously, the tarpaulin segment with flexible tarpaulin material is not only suspended from the upper horizontal edge but also fastened to the lower horizontal edge by the tarpaulin carriage. This has the advantage that the tarpaulin segment always has a vertically tensioned shape, so that the tarpaulin material is prevented from flapping, for example, while the utility vehicle is moving. In particular, in the vertical orientation, the tarpaulin segment is tensioned by the tarpaulin suspension device and the tarpaulin carriage, and this tension ensures a defined folding movement when the curtainsider system is opened or closed. The provision of a tarpaulin carriage also means that the tarpaulin segments are clamped with little play at the top by the tarpaulin suspension device and at the bottom by the tarpaulin carriage, so that the loads that normally act on the tarpaulin segments, caused by the centrifugal forces on the cargo when loading or moving, for example by a forklift truck, are brought to the second chambers or guide rails of the longitudinal beams, which advantageously ensures that these forces do not have to be brought to bear only by the sliding stanchions.

[0031] For convenience, each tarpaulin carriage has at least one load-bearing roller arranged above the guide rail and at least one counter roller arranged below the guide rail. The upper and lower load-bearing or guide rollers in each case increase the stability and robustness of the tarpaulin segments. Furthermore, the tarpaulin segments can absorb horizontal forces without being pushed out of the guide rail. In addition, the combination of the load-bearing and guide rollers increases the smooth running of the tarpaulin carriage as it moves along the guide rail, thus preventing it from getting stuck at all times. The forces normally acting on the tarpaulin segments are absorbed in particular by the lower counter roller.

[0032] It is convenient for the tarpaulin carriage and the sliding stanchion carriage to be displaceable on the same guide rail. This arrangement advantageously has a compact, component-reducing, space-saving construction. Furthermore, this arrangement makes installation easy and manufacturing cost-effective, as similar or identical components can be used.

[0033] According to a preferred embodiment, at least one tarpaulin segment is arranged between two adjacent sliding stanchions, which advantageously border the tarpaulin segments on both sides, giving the curtainsider system its versatility and smooth movement.

[0034] Preferably, at least one tarpaulin segment is connected to each adjacent sliding stanchion. In a particularly preferred embodiment, it is provided that the tarpaulin segments close the entire side opening of the utility vehicle and are therefore designed in the manner of a continuous side tarpaulin. In this case, at least one tarpaulin segment is connected, for example riveted, to the sliding stanchion so that the sliding stanchion is dragged along when the at least one tarpaulin segment is opened, which is also facilitated by the tarpaulin carriage and the sliding stanchion carriage being arranged to be displaceable on the same guide rail.

[0035] Preferably, the tarpaulin segment has at least one edge-to-side connecting element, which is connected to a corresponding counter-element of the sliding stanchion. The tarpaulin segment can be easily, intuitively and quickly attached to the sliding stanchion. Furthermore, in the event of a defect, the tarpaulin segment can be quickly and easily removed from the sliding stanchion. This makes it advantageous to replace the tarpaulin segment only at the relevant point in the curtainsider system, so that the time-consuming and costly replacement of the entire side tarpaulin is no longer necessary.

[0036] The connecting elements are expediently designed as kedars. Kedar connections provide a simple and immediately recognizable solution for assembling or disassembling tarpaulin segments. Kedars are inexpensive and can be manufactured in many variations. One advantage of kedar connections is that tensile forces are distributed evenly over the entire kedar rail, so that no tensile point loads act on the tarpaulin segments, which could eventually cause damage to the tarpaulin segments. As a result, the tarpaulin segments have an increased service life.

[0037] For ease of installation, the kedar is preferably designed as a zip kedar tape, which makes it easy to fit the tarpaulin segments into the kedar rail at the edges.

[0038] Conveniently, the counter element includes at least one kedar rail, preferably made of aluminum. The kedar rail is necessary for the kedar connection so that the tarpaulin segments can be fitted or inserted at their edges into grooves in the kedar rail. Advantageously, the kedar connection is a positive connection due to the insertion of the kedar into the kedar rail. Furthermore, the dead weight of an aluminum kedar rail is significantly reduced compared to steel, which generally makes it more cost-effective to operate a multi-purpose vehicle. Aluminum kedar rails can be easily manufactured in metric quantities by extrusion, making them extremely cost-effective.

[0039] According to a preferred embodiment, the counter element is attached to the sliding stanchion. Advantageously, the counter element is a separate component that is advantageously placed on the sliding stanchion depending on the application and attached to the sliding stanchion by a connecting means. This modular design provides an improved ease of installation. Furthermore, the counter element can be easily and quickly attached to the sliding stanchion.

[0040] Preferably, the kedar rail has two parallel grooves for receiving the kedar of the first tarpaulin segment and the kedar of the second tarpaulin segment. The kedar rail can therefore accommodate two tarpaulin segments at the same time. This advantageously facilitates a compact, space-saving design. In particular, if the grooves for accommodating the kedars are arranged close together, the appearance of the continuous tarpaulin is almost uninterrupted, so that, for example, a tarpaulin segment can be printed across the segment.

[0041] Preferably, the guide rollers are respectively arranged below the upper edges of the twin load-bearing rollers and above the lower edges of the twin load-bearing rollers.

[0042] Expediently, the twin load-bearing rollers each have a horizontal axis of rotation. Advantageously, the load-bearing rollers in the first chamber are arranged vertically, which allows displacement along the longitudinal beam, while at the same time the weight of the sliding stanchion is mainly borne by the twin load-bearing rollers.

[0043] Preferably, each guide roller has a vertical axis of rotation. The guide rollers, which are arranged horizontally within the stanchion suspension device, always align the sliding stanchion in an optimal position during displacement. This ensures that the sliding stanchion can move smoothly and without jamming.

[0044] According to a preferred embodiment, the vertical axis of rotation is located in the plane between the two load-bearing rollers of the twin load-bearing rollers. This structure and this arrangement of the rollers promotes optimal alignment and jam-free displacement of the sliding stanchions, regardless of the direction in which the sliding stanchions are moved along the longitudinal beam. Preferably, the vertical axis of rotation is located exactly centered between the two load-bearing rollers of the twin load-bearing rollers.

[0045] According to a preferred development, the horizontal rotation axis of the twin load-bearing rollers is in each case arranged below the guide roller, which advantageously provides sufficient free space for the sliding stanchions to always be optimally aligned with respect to the guide roller.

[0046] According to a preferred embodiment, the two guide rollers are arranged flush with each other. The two guide rollers are arranged flush and aligned with each other, which allows the sliding stanchion to move smoothly and without jamming.

[0047] Generally, it is advantageous for the twin load-bearing rollers to be arranged vertically. The weight of the sliding stanchion acts mainly on the twin load-bearing rollers, so the load-bearing rollers are advantageously arranged in a vertical position. On the one hand, this facilitates smooth displacement of the sliding stanchion and holding or supporting the sliding stanchion, since the twin load-bearing rollers can move along the longitudinal beam without getting stuck.

[0048] Preferably, the guide rollers are arranged horizontally. A horizontal arrangement of the guide rollers advantageously allows optimal alignment of the sliding stanchions in the event of displacement during the opening or closing process of the side tarpaulins.

[0049] According to a preferred embodiment, the outer diameter of the guide rollers protrudes beyond the width of the twin load-bearing rollers, which advantageously prevents the load-bearing rollers from coming into contact with the inner side wall of the chamber in which the twin load-bearing rollers and the guide rollers are arranged.

[0050] Preferably, the upper and lower edges of the guide roller are chamfered and / or rounded along their outer circumferential surfaces. On the one hand, the rounded or chamfered outer edges of the guide roller facilitate insertion of the guide roller into the first chamber of the longitudinal beam, and on the other hand, the rounded or chamfered outer edges facilitate jamming-free and smooth displacement of the sliding stanchion.

[0051] According to a design variant, the sliding stanchion has at least one guide element extending at least partially from the edge of the sliding stanchion body of the sliding stanchion. Furthermore, the guide element is preferably oriented outward, away from the loading platform. If cargo in the cargo space of the utility vehicle, for example by sliding, presses against the inner side of the curtainsider system, the curtainsider system can move easily and smoothly thanks to the sliding stanchion having the guide element. The guide element can advantageously be guided past obstacles or objects located in the cargo space. This advantageously allows the sliding stanchion to be guided past the cargo without getting stuck against the cargo.

[0052] According to another aspect of the present invention, an openable curtainsider system is provided for a multipurpose vehicle such as a truck, semi-trailer, transport vehicle, trailer, container, railroad freight car, etc. The openable curtainsider system includes at least one sliding stanchion having a stanchion suspension device displaceable along a first chamber of a longitudinal beam supported against the loading platform. The openable curtainsider system further includes at least one tarpaulin segment that at least partially closes a side opening of the multipurpose vehicle and is suspended by a tarpaulin suspension device displaceable along a second chamber of the longitudinal beam. The openable curtainsider system is characterized in that the tarpaulin segment has at least one edge-to-side connection element, and the connection element is connected to a corresponding counter element of the sliding stanchion. The tarpaulin segment can be easily, intuitively, and quickly attached to the sliding stanchion. Furthermore, in the event of a defect, the tarpaulin segment can be quickly and easily removed from the sliding stanchion. This makes it advantageous to replace tarpaulin segments only at the relevant point in the curtainsider system, so that the time-consuming and costly replacement of the entire side tarpaulin is no longer necessary.

[0053] The connecting elements are expediently designed as kedars. Kedar connections provide a simple and readily apparent solution for installing or removing tarpaulin segments. Kedars are inexpensive and can be manufactured in many variations. One advantage of kedar connections is that the tensile forces are distributed evenly over the entire kedar rail, so that no tensile point loads act on the tarpaulin segments, which could eventually cause damage to the tarpaulin segments. As a result, the tarpaulin segments have an increased service life.

[0054] For ease of installation, the kedar is preferably designed as a zip kedar tape, which makes it easy to fit the tarpaulin segments into the kedar rail at the edges.

[0055] Conveniently, the counter element comprises at least one kedar rail, preferably made from aluminium. The kedar rail is necessary for the kedar connection so that the tarpaulin segments can be fitted or inserted at their edges into grooves in the kedar rail. Advantageously, the kedar connection is a positive connection due to the insertion of the kedar into the kedar rail. Furthermore, the dead weight of an aluminium kedar rail is significantly reduced compared to steel, making travel by multi-purpose vehicles overall more cost-effective. Aluminium kedar rails can be easily manufactured in metre lengths by extrusion, making them extremely cost-effective.

[0056] According to a preferred embodiment, the counter element is mounted on the sliding stanchion. Advantageously, the counter element is a separate component that is advantageously placed on the sliding stanchion depending on the application and attached to the sliding stanchion by a connecting means. This modular design provides an improved ease of installation. Furthermore, the counter element can be easily and quickly attached to the sliding stanchion.

[0057] Preferably, the kedar rail has two parallel grooves for receiving the kedar of the first tarpaulin segment and the kedar of the second tarpaulin segment. The kedar rail can therefore accommodate two tarpaulin segments at the same time. This advantageously facilitates a compact, space-saving design. In particular, if the grooves for accommodating the kedars are arranged close together, the appearance of the continuous tarpaulin is almost uninterrupted, so that, for example, a tarpaulin segment can be printed across the segment.

[0058] According to a preferred embodiment, the tarpaulin segments are free of sliding stanchions in the area outside the edge-side connecting elements. The first and second tarpaulin segments are directly connected to the sliding stanchions by counter elements, so that the tarpaulin segments are arranged in one plane. When viewed from the outside, the sliding stanchions are located behind the first and second tarpaulin segments. The transition from the first to the second tarpaulin segment is flush and step-free on the outer side facing away from the utility vehicle. This advantageously facilitates a streamlined shape of the side tarpaulins, which advantageously allows for energy cost savings.

[0059] Adjacent tarpaulin segments are conveniently connected to one another by sliding stanchions. Advantageously, the first and second tarpaulin segments are connected by sliding stanchions. In this regard, the sliding stanchions advantageously transmit the tensile force not only to the first tarpaulin segment but also to the second tarpaulin segment, depending on the direction of movement. In addition, the connection by only one sliding stanchion allows for a space-saving, compact design of the curtainsider system.

[0060] Generally, it is advantageous that a plurality of tarpaulin segments between which sliding stanchions are arranged form a side tarpaulin, and that the side tarpaulin can be tensioned at its ends to position the movable sliding stanchions. Advantageously, the sliding stanchions and the tarpaulin segments form a unit, so that, depending on the direction of displacement, a pulling force can be transmitted from the tarpaulin segment to the sliding stanchions on the one hand, and from the sliding stanchions to the tarpaulin segment on the other. When the curtainsider system is closed, the tarpaulin segments are always positioned between two adjacent sliding stanchions in a tensioned and stretched state. As long as the side tarpaulins are tensioned at their ends, the sliding stanchions are always moved to a specific position.

[0061] The manufacturing costs of the side tarpaulins do not increase significantly compared to conventional tarpaulins, which consist of continuous tarpaulin segments and which have to be guided over sliding stanchions or central stanchions fixed to the base area. Furthermore, the side tarpaulins can be operated in the same way as conventional side tarpaulins.

[0062] Preferably, adjacent tarpaulin segments are connected to one another by means of sliding stanchions in each case. Furthermore, the sliding stanchions can preferably be moved into position when the tarpaulin segments are tensioned. This advantageously facilitates a compact, space-saving design of the curtainsider system. Furthermore, the curtainsider system can be produced cost-effectively due to the reduced number of components. Advantageously, the sliding stanchions are always in a defined position, which ensures a reliable stability of the curtainsider system.

[0063] Preferably, adjacent tarpaulin segments are in each case connected to one another by sliding stanchions, which can move into position when the tarpaulin segments are tensioned. As a result, the tarpaulin segments and the sliding stanchions form a force chain which, when subjected to a lateral tension, transmits and distributes this tension to all links of the force chain. This advantageously prevents different areas of the side tarpaulin from being subjected to different tensions.

[0064] Generally, it is advantageous that a plurality of tarpaulin segments together form a side tarpaulin, and that at least one edge tarpaulin segment can be connected to a tensioning device for tensioning the side tarpaulin. A plurality of tarpaulin segments arranged next to each other advantageously form a side tarpaulin that makes it possible to completely close the side opening of the utility vehicle. The side tarpaulin is tensioned by a tensioning device that is advantageously arranged on the tarpaulin segment.

[0065] When the tarpaulin is closed, the tarpaulin segments are preferably arranged in a common vertical plane. The tarpaulin segments are advantageously arranged flush or evenly with respect to one another. Furthermore, the tarpaulin segments are arranged parallel to one another. This is advantageous for appearance, for example, when the outer sides of the side tarpaulins are printed or coated with advertising. The uniform spacing and flush tarpaulin segments promote an overall high-quality impression of the curtainsider system.

[0066] When the side tarpaulins are tensioned, the tension is expediently applied to the tarpaulin segments by the sliding stanchions. The sliding stanchions advantageously absorb and also transmit part of the tension force, so that the tension force is advantageously transmitted uniformly to adjacent tarpaulin segments and adjacent sliding stanchions. As a result, the sliding stanchions can always move uniformly and without disruptive effects such as jamming, thus always facilitating reliable opening and closing of the side tarpaulins. Furthermore, the tension also results in the positioning of the sliding stanchions.

[0067] Preferably, when the side tarpaulin is opened, the sliding stanchions of the tarpaulin segments also move. The advantage is that a large amount of time is saved while opening the side tarpaulin, as the sliding stanchions move automatically almost simultaneously with the tarpaulin segments. As a result, side access to the cargo space of the multi-purpose vehicle is quick and free.

[0068] According to a preferred embodiment, the tarpaulin segments are exclusively connected to one another by a counter-element connected to the sliding stanchion, which counter-element preferably has two parallel grooves. The counter-element is designed as a separate component, preferably in the form of a grooved rail made of aluminum as explained above, and can be positioned at any point on the sliding stanchion depending on the application and can be connected by suitable connecting means. A total of two tarpaulin segments can be advantageously connected by two parallel keder grooves. This results in a compact and simple solution characterized by a high degree of ease of installation. Preferably, the counter-element is a one-piece part extending over the height of the tarpaulin segment, but it is also possible to provide several, preferably abutting, counter-elements instead of a one-piece part.

[0069] According to a further preferred embodiment, at the edges, the tarpaulin segments have at least a primarily continuous chedder housed in the counter-element. Furthermore, preferably, only the chedder transmits the tensile force. Advantageously, a uniform tensile force acts on the edges of the tarpaulin segments, so that, as a result, the tarpaulin segments are wrinkle-free in the closed state. Furthermore, the interaction between the tarpaulin segments and the sliding stanchions connected to them advantageously transmits the tensile or tensioning force across the entire edge-to-side connection between the sliding stanchions and the tarpaulin segments, so that, on the one hand, the tarpaulin material of the tarpaulin segments is not subjected to point stresses, and, on the other hand, the sliding stanchions can always move in an upright position without jamming. This promotes quiet and reliable opening and closing of the side tarpaulins and an increased service life of the curtainsider system.

[0070] It is expedient that adjacent tarpaulin segments are each connected to the same sliding stanchion by the edge-side connecting elements of the corresponding tarpaulin segments, which offers the advantage of a compact, space-saving design. Overall, this allows for fewer components and cost savings.

[0071] According to a further preferred embodiment, the tarpaulin segments have vertical and / or horizontal tensile reinforcements. When the side tarpaulins are opened or closed, the tensile forces acting on the tarpaulin segments increase. These tensile forces can overstretch the tarpaulin segments. In this regard, the tensile reinforcements advantageously serve to ensure that the tarpaulin segments are not overstretched and therefore not damaged, thereby guaranteeing an increased product service life.

[0072] According to a preferred embodiment, the sliding stanchions are guided at both ends without jamming and can always be moved in an upright position, in order to open and close the side tarpaulins smoothly and quietly.

[0073] According to one embodiment, the tarpaulin segments at least partially comprise strap material. The strap material advantageously increases the stability of the tarpaulin segments against possible excessive stretching of the tarpaulin material of the tarpaulin segments, so that the tarpaulin segments can absorb higher tensile forces. Furthermore, the strap material advantageously gives the tarpaulin segments a defined shape. During the opening and closing process, the tarpaulin segments always fold or unfold in an accordion-like manner. The tarpaulin segments always maintain a uniform and identical fold, so that the tarpaulin material is advantageously protected by the strap material. This allows the curtainsider system to open and close smoothly, while the tarpaulin segments have an increased service life.

[0074] Conveniently, the tarpaulin segment comprises at least partly strapping material.

[0075] The strap material expediently contains at least partly aramid fibers. This advantageously significantly increases the stability and tensile strength of the tarpaulin segments. The tarpaulin segments can advantageously absorb or transmit even higher tensile forces, so that the curtainsider system can also be used for the highest loads. The aramid fibers are preferably woven into at least the end regions of the straps.

[0076] Preferably, the strap material reduces the stretchability of the tarpaulin segments. The strap material advantageously prevents unwanted overstretching of the tarpaulin segments, so that the tarpaulin segments always maintain a precisely defined shape. Furthermore, the tensile forces are primarily borne by the strap material, which prevents overstretching or even tearing of the tarpaulin material.

[0077] According to a preferred embodiment, the strap material is sewn and / or welded to the tarpaulin segments. Sewing and / or welding offers the advantage of ensuring a particularly high level of robustness of this connection. The tarpaulin segments are advantageously designed to be durable, safe and secure. Furthermore, sewing and / or welding can be done easily and cheaply, so that the curtainsider system design is both cost-effective and efficient.

[0078] According to a further preferred embodiment, the strap material is arranged in at least one pocket of the tarpaulin segment. This type of covering of the strap material advantageously protects the strap material during displacement of the tarpaulin segment. This increases the durability of the connection between the strap material and the tarpaulin segment, thereby ensuring greater overall security and stability by advantageously preventing the strap material from chafing.

[0079] It is expedient that the strap material is at least partially connected to the tarpaulin suspension device. The strap material is advantageously used here as a reinforcement, as increased tensile forces act on the tarpaulin segments in the region of the connection between the tarpaulin suspension device and the tarpaulin segments. Advantageously, the tensile forces are at least primarily borne by the strap material, which reduces the load on the tarpaulin material and protects it.

[0080] According to one embodiment variant, the strapping material is designed as at least one strapping strip, which can be easily and quickly attached to the tarpaulin segments, making it cost-effective to manufacture and store.

[0081] Generally, it is advantageous for multiple strap strips to be connected vertically and horizontally to each tarpaulin segment. The tensile forces acting on the tarpaulin segments are primarily horizontal and vertical. By arranging the strap strips vertically and horizontally on the tarpaulin segments, the tensile forces are optimally absorbed and deflected, thereby protecting the tarpaulin segments or the tarpaulin material of the tarpaulin segments from unwanted excessive stretching. Furthermore, the tensile forces are optimally transmitted from the tarpaulin segments to the adjacent sliding stanchions, ensuring smooth and uniform opening and closing of the curtainsider system.

[0082] According to a preferred embodiment, the strap strips are arranged in a checkerboard pattern, which offers the advantage that this geometric arrangement can be produced easily and quickly and at the same time ensures tear resistance and increased stability against tensile forces and possible overstretching of the tarpaulin segments, especially within the crossing points of the strap strips, so that the tarpaulin segments have an increased load limit.

[0083] According to a further preferred embodiment, the strap strips are arranged at a defined distance from one another: the strap strips have a specific spacing next to one another and one after the other to ensure that the tensile forces can be transmitted uniformly from the tarpaulin segments and that the tarpaulin segments can be produced economically.

[0084] Preferably, the sliding stanchion has at least one guide element extending at least partially from the edge of the sliding stanchion body, the guide element oriented outward in a direction away from the loading platform. The guide element is advantageously provided over the entire height of the sliding stanchion body and forms a kind of wedge on each of its two end faces facing the direction of movement, with the wedge surface facing away from the utility vehicle. When the sliding stanchion moves, the front wedge in the direction of movement moves first with its tip at the greatest distance from the utility vehicle, followed by the wedge surface next to the tip, along with the load. In the case of an overhang load, the guide element is gradually moved away from the utility vehicle by the wedge surface. At the same time, the stanchion suspension device applies a reaction force to the cargo to move it out of the path of movement. This facilitates the elimination of the overhang load without the sliding stanchion having to swing in a pendulum manner away from the utility vehicle.

[0085] For convenience, the guide element and the sliding stanchion body are made in one piece. This advantageously eliminates the need for complex installation of the guide element. In addition, manufacturing costs are reduced. Such a one-piece part can be manufactured, for example, by bending sheet metal material.

[0086] Preferably, the guide element forms at least one wing-like edge of the sliding stanchion body in the longitudinal direction of the sliding stanchion. Advantageously, the guide element completely surrounds the sliding stanchion body on both sides so that the sliding stanchion can be guided normally over obstacles at any point, regardless of the direction in which the sliding stanchion moves.

[0087] According to a preferred embodiment, the guide element is designed as a folded edge of the sliding stanchion body. The folded edge can be manufactured easily and cheaply. Furthermore, the folded edge provides very good stability, so that the sliding stanchion can always be guided safely and reliably over obstacles when repositioning.

[0088] The guide elements are expediently rounded and / or chamfered on the outer edges. Because the sliding stanchions can come into contact with the tarpaulin segments, it is advantageous for the outer edges of the guide elements to be rounded and / or chamfered. This means that the tarpaulin material of the tarpaulin segments is not damaged, thus ensuring an increased service life.

[0089] Generally, the guide element is advantageously curved so as to define a cavity. Advantageously, the guide element is arranged in the sliding stanchion body in a compact and space-saving manner.

[0090] According to another preferred embodiment, the guide element has a triangular cross section: on the one hand, the triangular shape is easy to manufacture, and on the other hand, the triangular shape allows the sliding stanchion to be easily guided over obstacles in a sloped manner without getting stuck against them.

[0091] According to one embodiment, the guide element has at least one rounded outer edge with a radius in the longitudinal direction. The sliding stanchion does not have sharp or pointed outer edges, so that the tarpaulin segments cannot be damaged. In this respect, a reliable and safe movement of the sliding stanchion is guaranteed.

[0092] Expediently, the guide elements have a smooth front surface facing outwards in the longitudinal direction. When the sliding stanchions move, they may come into contact with the tarpaulin segments, which may roughen or wear away the tarpaulin material of the tarpaulin segments over time. A smooth surface gives the advantage that the tarpaulin material of the tarpaulin segments is protected, which advantageously increases the service life of the tarpaulin segments.

[0093] Expediently, the tarpaulin segments are arranged parallel to the front face of the guide element in the closed state. The guide element advantageously provides a shaped support for the tarpaulin segments. Furthermore, the tarpaulin segments can be optimally tensioned without undesired creases. Furthermore, tension forces can be transmitted uniformly from the sliding stanchion to the tarpaulin segments or from the tarpaulin segments to the sliding stanchion.

[0094] Preferably, the tarpaulin segments abut against the front face when closed. The front face of the guide element advantageously provides a kind of support surface for the tarpaulin segments, so that the tarpaulin segments can be given a defined shape. The tarpaulin segments are advantageously arranged with smooth, wrinkle-free edges, so that tensile forces can be transmitted very well. Furthermore, the guide element supports uniform folding or unfolding of the tarpaulin segments, which always ensures reliable and smooth opening and closing of the curtainsider system.

[0095] Generally, the tarpaulin segments connected to the sliding stanchions advantageously have, in their edge regions, lateral tarpaulin suspension devices that overlap the sliding stanchions. Advantageously, the sliding stanchions are therefore no longer visible because the corresponding tarpaulin segments are arranged in front of them. The sliding stanchions are therefore positioned between the cargo space and the connected tarpaulin segments. A further advantage is that when the curtainsider system is closed or tensioned, there is no need for additional fastening of the sliding stanchions, which saves time when opening and closing the curtainsider system.

[0096] Preferably, the stop body is riveted and / or screwed to the sliding stanchion. Depending on the application, the stop body can be quickly and easily connected to the sliding stanchion. This modular design advantageously provides variable design options, which ensures a high level of ease of installation.

[0097] According to an alternative design, the stop body is connected to the sliding stanchion in a bayonet manner. In this case, the stop body can advantageously be connected to the sliding stanchion, for example, by a bayonet latch connection. The advantage is that the stop body can be quickly and easily attached to or detached from the sliding stanchion without tools.

[0098] Preferably, each tarpaulin carriage is arranged on the opposite side to the tarpaulin hanging device, which advantageously facilitates the desired folding of the tarpaulin segments during the opening and closing process of the curtainsider system.

[0099] However, according to an advantageous embodiment, the tarpaulin carriage is not arranged on the side opposite the lateral tarpaulin suspension device. Due to the presence of kedders, or connecting elements, at the edges of the tarpaulin segments, it is not necessary to arrange the tarpaulin carriage below the horizontal edges of the tarpaulin segments, since the kedder connection of the tarpaulin segments with the sliding stanchions is sufficient to keep the tarpaulin segments in the desired shape in this area. The number of components is advantageously reduced, which saves costs and assembly time. In particular, this makes it possible to connect the tarpaulin carriage and the sliding stanchion carriage to the same guide rail.

[0100] According to a preferred embodiment, at least two tarpaulin carriages are arranged between adjacent sliding stanchion carriages. Since the tarpaulin segments have at least two tarpaulin carriages, preferably at least four, and usually six to twelve tarpaulin carriages, displaceable along the guide rails, the tarpaulin segments can advantageously be moved uniformly and without jamming. Furthermore, when the tarpaulin segments are closed, they are pulled vertically by the tarpaulin carriages, which prevents the tarpaulin segments from flapping when moving.

[0101] According to another preferred embodiment, the load-bearing rollers and / or counter rollers are detachably connected to the corresponding carriages by means of screws, which has the advantage that defective rollers can be replaced very quickly and easily.

[0102] Generally, it is advantageous for the load-bearing rollers and / or counter rollers to have a central running surface that contacts the narrow side of the guide rail, and for the load-bearing rollers and / or counter rollers to be provided with radially protruding collars on both sides of the running surface that can be brought into contact with the wide side of the guide rail to absorb horizontal forces. The load-bearing rollers or counter rollers are designed to be able to make optimal contact with the guide rail and are displaceable along the guide rail, thereby allowing the tarpaulin segments and sliding stanchions to move smoothly and without jamming. Furthermore, the load-bearing rollers or counter rollers can absorb horizontal forces without the tarpaulin carriages or sliding stanchion carriages being pushed out of the guide rail. The collars can be formed perpendicular to the central running surface. However, preferably, the collars are at a small angle to the vertical to increase the mobility of the rollers, allowing them to better adapt to deformations of the guide rail and to prevent jamming.

[0103] According to one embodiment, the tarpaulin segment has at least one tensile-resistant reinforcing strip, which advantageously allows tensile forces acting on the tarpaulin segment to be deflected in a defined manner without damaging the tarpaulin segment.

[0104] Preferably, the reinforcing strips are sewn and / or welded to the tarpaulin segments, which connects the reinforcing strips to the tarpaulin segments in a simple and cost-effective manner.

[0105] According to a design variant, the reinforcing strips at least partially comprise straps. This combination facilitates elastic stretching of the tarpaulin segments, which means that the tarpaulin segments can be equipped with different reinforcing strips depending on the application.

[0106] Expediently, the tarpaulin segment comprises at least one pair of reinforcing plates designed as folding aids, which advantageously serve to regulate the folding or unfolding of the tarpaulin segment during the opening and closing process of the curtainsider system.

[0107] According to a preferred embodiment, at least one pair of reinforcing plates is welded and / or sewn to the tarpaulin segment, which provides a simple and cost-effective way of creating a connection between the reinforcing plate pair and the tarpaulin segment.

[0108] According to a further preferred embodiment, at least one reinforcing plate pair is manufactured from tarpaulin material. Advantageously, the same tarpaulin material can be used for the reinforcing plate pair as for the tarpaulin segments, thereby saving costs. Furthermore, this facilitates welding to the tarpaulin segments, thereby providing a stable, physically bonded connection.

[0109] Generally, it is advantageous for the thickness of at least one reinforcing plate pair to be greater than the thickness of the tarpaulin segment. By providing an increased thickness of the reinforcing plate pair, a defined weight can be set in the lower region of the tarpaulin segment, so that the folding or unfolding of the tarpaulin segment takes place in a coordinated manner.

[0110] Preferably, the pair of reinforcing plates of at least one of the tarpaulin segments is arranged adjacent to the tarpaulin carriage, which on the one hand advantageously results in optimal folding or unfolding, and on the other hand, the pair of reinforcing plates acts as a protective element against wear in the area of ​​the guide rail, which therefore increases the service life of the tarpaulin segment by protecting it from chafing.

[0111] Preferably, at least one pair of reinforcing plates is assigned to each tarpaulin carriage. The pairs of reinforcing plates advantageously facilitate the folding and unfolding of the tarpaulin segments in a coordinated, uniform and accordion-like manner.

[0112] According to one variant embodiment, the tarpaulin segments are printed. Advantageously, the tarpaulin segments can be coated or printed on their outer side in order to provide advertising or promotion for public use.

[0113] Preferably, the tarpaulin segments can be folded in an accordion manner. In this case, each tarpaulin segment can advantageously be folded into multiple folds, in particular 2 to 12 folds, preferably 4 to 8 folds, when opened. In particular, the vertical straps of the tarpaulin segments form part of the folds that remain in the plane of the closed tarpaulin. In particular, the part of the tarpaulin segment arranged between the pair of reinforcing plates forms a fold fold, preferably extending perpendicularly in a plane parallel to the plane of the closed tarpaulin. When the side tarpaulins are open, the uniform accordion-like folding allows for the largest possible opening to the cargo space of the multi-purpose vehicle. Furthermore, it ensures that the curtainsider system can be easily opened and closed. In addition, the coordinated folding of the tarpaulin segments increases their service life. The uniform accordion-like folding minimizes lateral overhang when the side tarpaulins are open.

[0114] According to a preferred embodiment, all the load-bearing rollers and guide rollers of the stanchion suspension device are arranged in the first chamber. Furthermore, preferably, all the load-bearing rollers of the tarpaulin suspension device are arranged in the second chamber. The first and second chambers are conveniently separated from each other. Advantageously, the tarpaulin segments and the sliding stanchions can be guided along only one longitudinal beam. This results in a compact, space-saving design. In addition, the sliding stanchions and the tarpaulin segments can be removed or replaced from the longitudinal beam independently of each other, thus increasing the ease of installation.

[0115] Generally, it is advantageous for the tarpaulin suspension device to have guide rollers that are supported against the outer wall of the longitudinal beam, and for the outer wall of the longitudinal beam to be arranged above the first chamber. The guide rollers, inter alia, hold the tarpaulin segments at a distance from the longitudinal beam, thereby preventing wear of the tarpaulin segments. This increases the service life of the tarpaulin segments, as they are prevented from rubbing.

[0116] Preferably, the tarpaulin suspension device is equipped with a spring, for example in that the two axially guided parts are pretensioned in the tension direction by at least one tension spring. Advantageously, when the tarpaulin segments move, possible excessive stretching of the tarpaulin material of the tarpaulin segments is avoided or compensated for, since the spring used in the tarpaulin suspension device always ensures dynamic distance compensation between the tarpaulin segments and the tarpaulin suspension device. As a result, shifting the tarpaulin segments protects the material and therefore has a beneficial effect on the service life of the product.

[0117] According to another preferred embodiment, the outer wall of the longitudinal beam is arranged below the second chamber. This arrangement advantageously facilitates optimal folding and unfolding of the tarpaulin segments. Furthermore, the tarpaulin segments are advantageously always arranged at a certain distance from the longitudinal beam, so that the tarpaulin material does not rub against the longitudinal beam on the inner side of the tarpaulin segments.

[0118] Conveniently, the sliding stanchion body includes at least one kedar rail, which advantageously allows for quick and easy mounting and connection of, for example, tarpaulin segments or tensioning devices, each having a corresponding kedar.

[0119] According to a preferred embodiment, the sliding stanchion body preferably has a central recess into which at least one kedar rail can be inserted. Furthermore, when the kedar rail is inserted, one end face of the kedar rail is at least nearly flush with one front face of the sliding stanchion body. The sliding stanchion is advantageously very easy to install, as the kedar rail is connected into the recess of the sliding stanchion with an accurate fit. Furthermore, a space-saving and compact sliding stanchion is provided in which the kedar rail can be incorporated almost invisible. The sliding stanchion and the kedar rail have flush front faces when installed, which advantageously prevents the tarpaulin segments from rubbing along unwanted edges during the opening and closing process.

[0120] Preferably, at least one kedar rail extends across the effective height of the sliding stanchion body, which advantageously allows material and weight to be saved or reduced, thus providing an economically advantageous combination of sliding stanchion and kedar rail.

[0121] The further features of the sliding stanchion described above in connection with the curtainsider system according to the invention, as well as the advantages and properties thereof, may also be implemented in the sliding stanchion according to the invention and are hereby expressly included.

[0122] According to one aspect of the present invention, there is provided a method for manufacturing an openable curtain-sider system for multipurpose vehicles such as trucks, semi-trailers, transport vehicles, trailers, containers, rail cars, etc. The method comprises providing tarpaulin segments having kedders on their edges, inserting the kedders into grooves in kedder rails, and attaching the kedder rails to sliding stanchions. The above method has two major advantages: on the one hand, the side tarpaulins can be installed quickly, efficiently, and economically, and on the other hand, they can be easily replaced, for example, if the tarpaulin segments or the sliding stanchions are defective.

[0123] The method according to the invention therefore first connects the kedars of the tarpaulin segments to the kedar rails, thus creating a continuous chain of alternating tarpaulin segments and kedar rails. However, in this case, the kedar rails can be attached to the stanchion bodies of the sliding stanchions, which can therefore already be arranged, in particular, on the longitudinal beams and / or guide rails. However, it is also possible to attach the kedar rails to the corresponding sliding stanchions immediately after connecting the tarpaulin segments to the channel rails, which for this purpose have two grooves, and it is also possible to continue with the kedar rails and the kedars of the tarpaulin segments that run away from another kedar rail.

[0124] For convenience, the tarpaulin hanging device is connected to the tarpaulin segment. The tarpaulin hanging device is preferably used to hold and move the tarpaulin segment so that it always maintains the desired shape. Furthermore, the tarpaulin hanging device mainly bears the weight of the tarpaulin segment. Attaching the tarpaulin hanging device is advantageously performed before the tarpaulin segment is prepared, so that the tarpaulin segment is already provided with the tarpaulin hanging device before the kedder is inserted. This is advantageous, especially when the tarpaulin segment has straps extending vertically from the tarpaulin hanging device, because the tarpaulin hanging device can be better connected to the straps before the tarpaulin segment is prepared. The tarpaulin segment can be hung from the longitudinal beam by the tarpaulin hanging device before the kedder is inserted into the kedder rail.

[0125] According to a preferred embodiment, the tarpaulin suspension device is connected to the tarpaulin segment before the kedder is inserted into the groove. Pre-assembled tarpaulin segments can be connected to the curtainsider system even more quickly, thereby ensuring ease of assembly.

[0126] Preferably, the tarpaulin carriage is connected to the tarpaulin segments. This connection of the tarpaulin carriage ensures that the tarpaulin segments always maintain their shape along the guide rails. Furthermore, flapping during movement is advantageously avoided. Furthermore, the opening and closing process of the tarpaulin segments is always coordinated and smooth.

[0127] According to a further preferred embodiment, the tarpaulin carriage is connected to the tarpaulin segment before the kedder is inserted into the groove. To save time, the tarpaulin segment can advantageously be delivered pre-assembled with the connected tarpaulin carriage, so that the tarpaulin segment can be quickly replaced or connected to the sliding stanchion. The tarpaulin carriage can therefore already be pushed into the guard rail before the kedder of the tarpaulin segment is connected to the kedder rail.

[0128] Generally, it is advantageous for the kedar rail to be attached to the sliding stanchion by riveting. The riveting process ensures a particularly high level of stability of the connection between the kedar rail and the sliding stanchion.

[0129] According to one design variant, the kedar is connected to the tarpaulin segments at the edges by sewing, welding, gluing, or a combination thereof. The kedar is connected to the tarpaulin segments using conventional methods, thus providing a cost-effective and reliable connection.

[0130] According to another preferred embodiment, the kedar has kedar fins to which the tarpaulin segments are connected at their edges by sewing, welding, gluing, or a combination thereof. The kedar fins facilitate connection to the tarpaulin segments. Furthermore, the kedar can be easily replaced without damaging the tarpaulin segments or the tarpaulin material.

[0131] According to another aspect of the present invention, there is provided a method for manufacturing an openable curtainsider system for multipurpose vehicles such as trucks, semi-trailers, transport vehicles, trailers, containers, rail cars, etc. The method comprises providing a tarpaulin segment with an edge-side kedar rail having at least one groove. The method further comprises inserting a corresponding connecting element into the groove of the kedar rail. Depending on the application, the tarpaulin segment is advantageously equipped with the kedar rail at this point. In this way, the tarpaulin wall system offers increased versatility and ease of installation.

[0132] Preferably, the kedar rails are attached to the tarpaulin segments at their edges by sewing, welding, gluing or a combination thereof. To this extent, the connection of the kedar rails with the tarpaulin segments is advantageously a stable and reliable connection. Furthermore, the connection is cost-effective and efficient.

[0133] Generally, the kedar rail advantageously has kedar tape by means of which the tarpaulin segments are connected at their edges by sewing, welding, gluing or a combination thereof. When the kedar rail is replaced, the kedar tape is cut open, so that the tarpaulin segments or their tarpaulin material are not damaged.

[0134] Preferably, the corresponding connecting element is designed as a longitudinally extending rod or as a longitudinally extending tube, which is connected to the sliding stanchion by a screw connection and / or welding. The corresponding connecting element is advantageously a separate component that is attached to the sliding stanchion. In this respect, this method advantageously provides increased versatility and ease of installation.

[0135] According to one embodiment, the corresponding connecting element is designed as a bend or protrusion extending from the sliding stanchion. In this respect, the corresponding connecting element is formed integrally with the sliding stanchion. The advantage is that the number of components is reduced overall, thereby reducing costs. Furthermore, the integral connecting element is very robust, providing a reliable and safe curtainsider system.

[0136] For convenience, at least one pair of reinforcing plates designed as a folding aid is sewn and / or welded to the inner and / or outer side of the tarpaulin segment. If a tarpaulin segment requires further pairs of reinforcing plates, these can be attached to the tarpaulin segment during assembly. This advantageously improves the ease and versatility of installation of the tarpaulin segment.

[0137] Preferably, in the method, the sliding stanchion is designed as described above.

[0138] As a direct result of the method, the manufacturing process produces a curtainsider system that is easy to manufacture, simple to operate and reliable. Thus, according to one aspect of the present invention, there is provided a curtainsider system obtainable by the method.

[0139] Further advantages, properties, features and developments of the claimed invention will become apparent from the following description of preferred embodiments and from the dependent claims.

[0140] The invention will now be described in more detail with reference to the accompanying drawings. [Brief explanation of the drawings]

[0142] Figure 1 shows an exemplary embodiment of a curtainsider system 10. By way of example, a utility vehicle 11 with a semi-trailer is shown in side view in Figure 1. The curtainsider system 10 is positioned between a longitudinal beam 14 and a guide rail 26 assigned to a loading platform 15. Furthermore, the curtainsider system 10 comprises a plurality of tarpaulin segments 16 positioned between vertical sliding stanchions 12. In this respect, Figure 1 shows schematically a first tarpaulin segment 16a and a second tarpaulin segment 16b, each of which is connected to the sliding stanchion 12 by its vertical edge 16e.

[0143] The sliding stanchions 12 have a sliding stanchion body 12a having an upper end 12b and a lower end 12c. At this point, each sliding stanchion 12 is connected by a stanchion suspension device 13 that is displaceable within a first chamber 14a, shown in FIG. 5, of a longitudinal beam 14.

[0144] Furthermore, the sliding stanchion 12 has at its lower end 12c a sliding stanchion carriage 25 which is displaceable along a guide rail 26. The sliding stanchion body 12a includes a kedar rail 22 with a double groove 22a, as shown in Figures 5, 8 and 9. The kedar rail 22 attached to the sliding stanchion 12 forms a counter element 20 for the kedar connection 21 with the tarpaulin segment 16.

[0145] Each tarpaulin segment 16 has an upper horizontal edge 16c and a lower horizontal edge 16d. Furthermore, each tarpaulin segment 16 has at least one vertical edge 16e on which a keder 23; 24 is arranged. The keder 23; 24 of the tarpaulin segment 16 together with the counter element 20 of the sliding stanchion 12 form a connecting element 19 of the tarpaulin segment 16, so that the tarpaulin segment 16 can be connected to the sliding stanchion 12 by a keder connection 21.

[0146] The upper horizontal edge 16c of the tarpaulin segment 16 carries a tarpaulin hanging device 18, and the lower horizontal edge 16d of the tarpaulin segment 16 carries a tarpaulin carriage 35. As a result, the tarpaulin segment 16 can be displaced along the second chamber 14b of the longitudinal beam 14, shown in Figure 5, by means of the tarpaulin hanging device 18. Furthermore, the tarpaulin segment 16 can be displaced along the guide rail 26 by means of the tarpaulin carriage 35. The tarpaulin hanging device 18 is described in detail, for example, in German Utility Model No. 20 2015 006 044 (U1), the disclosure of which is incorporated herein by reference.

[0147] When a sliding stanchion 12 connected to a tarpaulin segment 16 by a keder connection 21 is displaced, a tensile force acts on the tarpaulin segment 16 along the vertical edge 16e. This tensile force is transmitted to the adjacent sliding stanchion 12, so that this stanchion also always displaces in one direction of displacement. The combination of the sliding stanchions 12 and tarpaulin segments 16 described above therefore forms an openable side tarpaulin 9 for a multipurpose vehicle.

[0148] To ensure that the tarpaulin segments 16 are not overstretched and to ensure that they have a certain robustness, the tarpaulin segments 16 have tensile reinforcements 28; 43 sewn or welded to them.

[0149] The tension reinforcements 28; 43 also at least partially comprise straps 29; 29a. Advantageously, in the middle of the tension reinforcements 28; 43 or strap strips 29; 29a, the tarpaulin segments 16 are protected from excessive stretching.

[0150] Furthermore, the tension reinforcements 28; 43 preferably act as folding aids. During opening of the curtainsider system 10, the sliding stanchions 12 are displaced and therefore the tarpaulin segments 16 are also displaced. At this point, the tarpaulin segments 16 are folded together like an accordion.

[0151] 2 shows a perspective view of the curtainsider system 10 by way of example. In this exemplary embodiment, it can be clearly seen that the tarpaulin segments 16 have tension reinforcements 28; 43 arranged in a checkerboard pattern with the tarpaulin segments 16. Furthermore, the vertical tension reinforcements 28; 43 are connected on one side to the tarpaulin carriage 35 in the area of ​​the guide rail 26 and on the other side to the tarpaulin suspension device 18 in the area of ​​the longitudinal beam 14.

[0152] Figure 3 shows an enlarged front view of a detail of the curtainsider system 10. A tarpaulin segment 16 is positioned in the middle and is framed at each of its vertical edges 16e by sliding stanchions 12. An upper horizontal edge 16c of the tarpaulin segment 16 is attached to a tarpaulin hanging device 18 and a lateral tarpaulin hanging device 18a, which are also located in the second chamber 14b of the longitudinal beam 14. A lower horizontal edge 16d of the tarpaulin segment 16 is connected to a tarpaulin carriage 35, which is covered by the tarpaulin segment 16 in Figure 3.

[0153] The two vertical edges 16e of the tarpaulin segment 16 each have a keder 23; 24 that is positioned in a groove 22a of the keder rail 22. The keder rail 22 is arranged longitudinally on the sliding stanchion 12 and fastened to the sliding stanchion 12 by means of screws. The keder connection 21 establishes a positive connection, so that the tensile force exerted by the sliding stanchion 12 on the tarpaulin segment 16 can act uniformly over the entire vertical edge 16e of the tarpaulin segment 16. Furthermore, the tarpaulin segment 16 can transmit the same tensile force to the sliding stanchion 12 by means of the keder connection 21, depending on the displacement direction of the side tarpaulin 9.

[0154] Figure 4 shows the same view as Figure 3, but without the tarpaulin segment 16. In Figure 4, the two sliding stanchions 12 are fully visible in front view, including the lower tarpaulin carriage 35 which was previously covered by the tarpaulin segment 16.

[0155] Each sliding stanchion 12 has a so-called guide element 30, 30a longitudinally along its sliding stanchion body 12a. If cargo in the cargo space moves out of the loading platform 15, the sliding stanchion 12 can be easily guided past the cargo by the guide element 30 during the opening and closing process.

[0156] 5 shows a detail of the upper region 12b of the sliding stanchion 12. In particular, the longitudinal beam 14 is clearly visible, and a cross section of the longitudinal beam 14 is shown so that the first chamber 14a and the second chamber 14b of the longitudinal beam 14 are visible.

[0157] 5, the sliding stanchion 12 is shown with the stanchion suspension device 13 visible. The stanchion suspension device 13 is positioned on the side facing the loading platform 15. The stanchion suspension device 13 is designed as a twin load-bearing roller 33 and has load-bearing rollers 33a; 33b which are displaceable in the first chamber 14a of the longitudinal beam 14.

[0158] 5 further shows tarpaulin hanging devices 18 or lateral tarpaulin hanging devices 18a having a total of two load-bearing rollers 18b arranged in and displaceable within the second chamber 14b of the longitudinal beam 14. Furthermore, each tarpaulin hanging device 18; 18a has two horizontal guide rollers 18c displaceable along the outer wall 14c of the longitudinal beam 14. It can be clearly seen that an inclined bend 31 extends outward from the sliding stanchion body 12a, which bend defines a guide element 30.

[0159] 5 also clearly shows the kedar rail 22 located centrally along the sliding stanchion body 12a. The kedar rail 22 includes a double groove 22a into which the kedars 23, 24 of the tarpaulin segment 16 can be fitted on the left and right sides, respectively.

[0160] As a result, the first tarpaulin segment 16a and the second tarpaulin segment 16b can be connected to one sliding stanchion 12 by the first keder 23 and the second keder 24.

[0161] Figure 6 shows a cross-sectional view of the upper end 12b of the sliding stanchion body 12a. The longitudinal beam 14 having a first chamber 14a and a second chamber 14b is clearly visible, both chambers 14a, 14b being located at a distance from each other. The stanchion suspension device 13 is located in the first chamber 14a, together with two twin load-bearing rollers 33, which in this view have upper and lower edges 45, 46.

[0162] The sliding stanchion 12 is arranged below the stanchion suspension device 13 and is connected to the stanchion suspension device 13 by frictional coupling and form-fitting. The tarpaulin suspension device 18; 18a is located in the second chamber 14b of the longitudinal beam 14. The tarpaulin suspension device 18; 18a has a vertical load-bearing roller 18b and a horizontal guide roller 18c. In this respect, the horizontal guide roller 18c is guided on the outer wall 14c of the longitudinal beam 14. The outer wall 14c is arranged on the side facing away from the loading platform 15.

[0163] 7 shows the lower end 12c of the sliding stanchion body 12a. At the lower end 12c, the sliding stanchion 12 has a sliding stanchion carriage 25 that is displaceable along a guide rail 26. The sliding stanchion carriage 25 includes two upper load-bearing rollers 25a and a lower counter roller 25b. The load-bearing rollers 25a and the counter rollers 25b each have a collar 25d that protrudes beyond the running surface 25c, so that the load-bearing rollers 25a and the counter rollers 25b can absorb horizontal forces without being pushed out of the guide rail 26.

[0164] Furthermore, Figure 7 shows a stop body 27 which serves as an additional protection for the sliding stanchion carriage 25. The stop body 27 transmits horizontal forces which may be caused in particular by sliding cargo to the sliding stanchion body 12a, so that the sliding stanchion carriage 25 of the sliding stanchion 12 is always connected to the guide rail 26 in a displaceable manner.

[0165] Figure 8 shows the sliding stanchion 12 from above. The sliding stanchion 12 has an overall mirror-symmetrical shape characterized by a plane of symmetry E. The kedar rail 22 is centrally located within the sliding stanchion 12. The kedar rail 22 has a double groove 22a into which the kedars 23, 24 of the first tarpaulin segment 16a and the second tarpaulin segment 16b can be inserted. The double groove 22a of the kedar rail 22 has an open slot extending along the kedar rail 22 as a whole. Each tarpaulin segment 16 emerges from this open slot to the left or right.

[0166] It is important that the opening slot is narrow so that the two emerging tarpaulin segments 16a; 16b are positioned flush with each other with as little gap as possible.

[0167] The stanchion suspension device 13, in particular, can be clearly seen in FIG. 8. The stanchion suspension device 13 has so-called twin load-bearing rollers 33 positioned in a vertical orientation on the left and right sides of the kedar rail 22. Each twin load-bearing roller 33 includes a first load-bearing roller 33a and a second load-bearing roller 33b, each of which defines a width 39 and has the same rotation axis 36. The horizontal guide rollers 34 of the stanchion suspension device 13 are disposed outward relative to the twin load-bearing rollers 33 in the direction of movement of the sliding stanchion 12. Furthermore, each guide roller 34 has a vertical rotation axis 37. In addition, the guide rollers 34 have an outer diameter 38 that is greater than the width 39 of the twin load-bearing rollers 33.

[0168] 8 also shows a first exemplary embodiment of a guide element 30. The guide element 30 of the sliding stanchion 12 extends from the sliding stanchion body 12a at a certain angle W. The guide element 30 is designed as a bend 31 with a radius R, where the outer edge 32 points in the direction towards the tarpaulin segment 16.

[0169] Figure 9 shows the upper end 12b of the sliding stanchion 12 with the stanchion suspension device 13 connected to the sliding stanchion body 12a. Because the longitudinal beam 14 is not shown in Figure 9, both the twin load-bearing rollers 33 and the guide roller 34 of the stanchion suspension device 13 are clearly visible. The horizontal guide roller 34 of the stanchion suspension device 13 has an upper edge 40 and a lower edge 41 located on the outer circumferential surface 42 of the guide roller 34.

[0170] Additionally, a second exemplary embodiment of a guide element 30 of the sliding stanchion 12 is shown in Figure 9. The guide element 30 has a total of three bends 31 in the sliding stanchion body 12a. Each bend 31 has a radius R. The guide element 30 is bent at an angle W from the sliding stanchion body 12a such that the guide element 30 forms a triangular cross section containing a cavity H. Here, each outer edge 32 is rounded in the direction of travel.

[0171] Furthermore, the guide element 30 has a smooth front surface 30 a arranged facing away from the loading platform 15 .

[0172] The invention works as follows: a closed and latched curtainsider system 10 is unlocked at the corresponding point so that the curtainsider system 10 or the side tarpaulin 9 can be moved or opened. With the aid of a rod with a hook, the curtainsider system 10 can be manually opened by means of a strap loop. In this case, the user pulls the strap loop so that the sliding stanchions 12 and the tarpaulin segments 16 connected to the sliding stanchions 12 follow the strap loop in the opening direction.

[0173] When shifted in the opening direction, the tarpaulin segment 16 folds like an accordion, so that the sliding stanchion 12 and the folded tarpaulin segment 16 are positioned at the corners of the utility vehicle 11, thereby freeing up the side opening 17 of the utility vehicle 11.

[0174] To close the curtainsider system 10, a second strap loop located on the opposite side, connected to another stanchion hanging device 13, is manually pulled in the other direction by a rod with a hook, so that the sliding stanchion 12 or the tarpaulin segment 16 follows the direction of displacement. The tarpaulin segment 16 unfolds, thereby forming a smooth, flat wall. When the entire side opening 17 is covered by the curtainsider system 10, the curtainsider system 10 is latched and pulled by a latching device and, if necessary, by a pulling device. At this point, the utility vehicle 11 is ready to drive away.

[0175] If cargo slides within the cargo space to the extent that it becomes an obstacle for the sliding stanchion 12, the sliding stanchion 12 can be guided past the obstacle simply by using its guide element 30.

[0176] The side tarpaulin 9 or curtainsider system 10 no longer simply functions as a cover: the side tarpaulin 9 is divided into a number of tarpaulin segments 16 which are connected directly to the sliding stanchions 12. In this way, the tarpaulin segments 16 take on the function of chain links between the sliding stanchions 12.

[0177] In the event of damage to the tarpaulin segment 16, the tarpaulin segment 16 shall be replaced by, for example, the following steps: in this respect, the tarpaulin material is first cut into rectangular tarpaulin segments 16, and the upper horizontal edge 16c of the tarpaulin segment 16 is assigned to the longitudinal beam 14 and the lower horizontal edge 16d of the tarpaulin segment 16 is assigned to the guide rail 26.

[0178] In a next step, at least one keder 23; 24 is connected next to the vertical edge 16e of the tarpaulin segment 16. This vertical edge 16e of the tarpaulin segment 16 is correspondingly assigned to the sliding stanchion 12. This is followed by inserting the keder 23; 24 connected to the tarpaulin segment 16 by form-fitting or material bonding into the groove 22a of the keder rail 22. The keder rail 22 connected to the tarpaulin segment 16 is then attached to the sliding stanchion 12 by rivets or screws.

[0179] The upper horizontal edge 16c of the tarpaulin segment 16 is connected to a tarpaulin hanging device 18; 18a, which is thus suspended in a second chamber 14b of the longitudinal beam 14 and is displaceable along the longitudinal beam 14.

[0180] In a final step, the tarpaulin segments 16 are connected to tarpaulin carriages 35 which are displaceable along guide rails 26 assigned to the loading platform 15. Correspondingly, the entire curtainsider system 10 has a modular construction, so that the individual components can be exchanged and replaced very easily and quickly.

[0181] Furthermore, the curtainsider system 10 can be automated so that it can be opened and closed automatically under computer control.

[0182] Figure 10 shows an alternative embodiment of an openable curtainsider system 100 for a utility vehicle 110, in which the wrinkle-free inner surface 91 of the closed side tarpaulin 90 is shown, the inner surface 91 of the side tarpaulin 90 facing the loading platform 150, which is shown as a dashed line. In contrast to the previous exemplary embodiment, the side tarpaulin 90 in Figure 10 does not have individual tarpaulin segments. The side tarpaulin 90 is here designed as a one-piece continuous side tarpaulin 90 or comprises only a single tarpaulin segment forming the side tarpaulin 90.

[0183] FIG. 11 shows an enlarged detail of the closed curtainsider system 100 according to FIG.

[0184] 10 and 11 has an upper horizontal edge 90a assigned to the longitudinal beam 140, and in one area of ​​the upper horizontal edge 90a the side tarpaulin 90 comprises a tarpaulin suspension device connected to the longitudinal beam 140 or displaceable along the longitudinal beam 140, although the tarpaulin suspension device is not shown in Figures 10 or 11. Furthermore, the side tarpaulin 90 has a lower horizontal edge 90b on the side opposite to the upper horizontal edge 90a, this lower edge being assigned to the loading platform 150 or the guide rail 260.

[0185] Furthermore, the curtainsider system 100 shown in Figures 10 and 11 includes a plurality of sliding stanchions 120, each having a sliding stanchion body 120a with an upper end 120b and a lower end 120c, and the sliding stanchions 120 are displaceable along the longitudinal beam 140 and an oppositely located guide rail 260 that is fastened to the loading platform 150 by a stanchion suspension device and a sliding stanchion carriage, although the stanchion suspension device and the sliding stanchion carriage are not shown in Figures 10 and 11.

[0186] Furthermore, the side tarpaulin 90 has fastening elements 190, such as hook-and-loop fastener strips, on the inner surface 91, which are arranged, inter alia, in the upper, middle and lower regions of the side tarpaulin 90. Furthermore, the side tarpaulin 90 is riveted to the sliding stanchions 120.

[0187] The side tarpaulin 90 has a triangular plate 440 arranged along the upper edge 90a of the side tarpaulin 90 so that the side tarpaulin 90 can be folded or unfolded like an accordion during the opening and closing process of the curtainsider system 100. Therefore, the triangular plate 440 is designed as a tarpaulin folding aid. Furthermore, the side tarpaulin 90 has a metal strip 430 made of a steel material arranged in a pocket aligned horizontally in the longitudinal direction of the side tarpaulin 90, and this metal strip 430 supports the folding and unfolding of the side tarpaulin 90. Therefore, the metal strip 430 is arranged parallel to the longitudinal beam 140 or the guide rail 260 when the side tarpaulin 90 is in the closed state.

[0188] To provide the side tarpaulin 90 with excellent mechanical stability that protects it from tearing, the side tarpaulin 90 has vertical straps 290 as tensile reinforcements 280. The straps 290 are sewn to the side tarpaulin 90 and comprise an aramid fiber reinforced strap material. Furthermore, the side tarpaulin 90 is connected to a tarpaulin carriage 350 by the vertical straps 290 in an area along the lower horizontal edge 90b of the side tarpaulin 90. The tarpaulin carriage 350 is connected to a guide rail 260 of the loading platform 150 and is displaceable along the guide rail 260. Furthermore, the side tarpaulin 90 is riveted to the tarpaulin carriage 350. Therefore, the straps 290 are positioned parallel to the sliding stanchions 120 when the side tarpaulin 90 is in the closed state. In addition, two triangular plates 440 are disposed between two adjacent vertical straps 290 .

[0189] FIG. 12 shows a cross section of a longitudinal beam 140 having a first chamber 140a and a second chamber 140b. Two twin load-bearing rollers 330 of the stanchion hanging device 130 are displaceably arranged in series within the first chamber 140a of the longitudinal beam 140. Each twin load-bearing roller 330 here includes a first load-bearing roller 330a and a second load-bearing roller 330b. Furthermore, two guide rollers 340 of the stanchion hanging device 130 are displaceably arranged within the first chamber 140a. The guide rollers 340 are positioned outside the twin load-bearing rollers 330 in the direction of movement of the sliding stanchion 120. Therefore, the arrangement of the twin load-bearing rollers 330 and the guide rollers 340 of the stanchion hanging device 130 corresponds to the previous exemplary embodiment. Furthermore, the stanchion hanging device 130 has a bent portion 131 that is riveted to the sliding stanchion body 120a at the upper end 120b of the sliding stanchion 120. As a result, the sliding stanchion 120 is placed on the longitudinal beam 140 by the stanchion hanging device 130 and is guided so as to be displaceable along the longitudinal beam 140.

[0190] The load-bearing roller 180b of the tarpaulin hanging device 180 is displaceably arranged in the second chamber 140b of the longitudinal beam 140. Furthermore, the tarpaulin hanging device 180 includes a guide roller 180c that is displaceable along the outer wall 140c of the longitudinal beam 140. The tarpaulin hanging device 180 further includes a slot receptacle into which a vertical strap 290 is guided in a loop manner, and the vertical strap 290 is also sewn to the side tarpaulin 90. As a result, the side tarpaulin 90 is placed on the longitudinal beam 140 by the tarpaulin hanging device 180 and is guided so as to be displaceable along the longitudinal beam 140.

[0191] 13 shows an enlarged detailed perspective view of a guide rail 260 connected to the bed 150 of the utility vehicle 110. The guide rail 260 includes at least one removable guide rail segment 261 that is prevented from falling off by two locking elements 264.

[0192] The attached guide rail segment 261 is aligned and flush with the remaining guide rail 260, so that the tarpaulin carriage 350 and the sliding stanchion carriage 250 can move smoothly without bumps or jams. The purpose of the removable guide rail segment 261 is to allow the sliding stanchion carriage 250 and the tarpaulin carriage 350 to pass through the gap in the guide rail 260, for example, to be able to raise the roof of the utility vehicle 110 without damaging the sliding stanchion 120 and the side tarpaulin 90.

[0193] 13 further shows the lower end 120c of the sliding stanchion body 120a of the sliding stanchion 120 with the connected sliding stanchion carriage 250, where the upper load-bearing roller 250a and lower counter roller 250b of the sliding stanchion carriage 250 are visible. In this regard, the upper load-bearing roller 250a is disposed on the upper narrow side of the guide rail 260, and the lower counter roller 250b is disposed on the opposite lower narrow side of the guide rail 260. The sliding stanchion carriage 250 includes a total of two load-bearing rollers 250a arranged in series and two counter rollers 250b arranged in series that are riveted to the sliding stanchion body 120a of the sliding stanchion 120 by fastening plates 251.

[0194] Additionally, an end face portion of end stop body 271 can be seen behind upper load bearing roller 250a.

[0195] 14 shows a perspective view of a portion of the guide rail 260 with a removed guide rail segment 261, which has a first pin 262 and an opposite second pin 263, each extending perpendicularly from the same wide side of the guide rail segment 261 in the same direction. It can be seen that the guide rail segment 261 is designed as an elongated flat piece with a rectangular cross section. Furthermore, the first pin 262 and the second pin 263 each have a cylindrical shape, and the first pin 262 and the second pin 263 are welded to the guide rail segment 261.

[0196] Furthermore, the first pin 262 has a first hole 262a and the second pin 263 has a second hole 263a, the first hole 262a and the second hole 263a being disposed transversely to the longitudinal axis of the first pin 262 and the longitudinal axis of the second pin 263, respectively.

[0197] To mount the guide rail segment 261 on the utility vehicle 110 , the first pin 262 of the guide rail segment 261 is inserted into the first receptacle 265 a of the first fastening element 265 .

[0198] Furthermore, the second pin 263 of the guide rail segment 261 is inserted into the second receptacle 266 a of the second fastening element 266 .

[0199] The first fastening element 265 and the second fastening element 266 are connected to the cargo bed 150 of the multi-purpose vehicle 110 by a screwed or riveted connection, and the first fastening element 265 and the second fastening element 266 each have a rectangular parallelepiped body, and the longitudinal sides of the first fastening element 265 and the longitudinal sides of the second fastening element 266 are arranged parallel to the cargo bed 150.

[0200] The first receptacle 265a of the first fastening element 265 has a first through hole 265b disposed transversely relative to the first receptacle 265a. The second receptacle 266a of the second fastening element 266 has a second through hole 266b disposed transversely relative to the second receptacle 266a. Thus, the first pin 262 and the second pin 263 of the guide rail segment 261 are inserted into the first receptacle 265a of the first fastening element 265 and the second receptacle 266a of the second fastening element 266 by a bayonet connection. In this respect, the first hole 262a of the first pin 262 and the first hole 265b of the first receptacle 265a of the first fastening element 265 are aligned. Furthermore, the second hole 263a of the second pin 263 and the second hole 266b of the second receptacle 266a of the second fastening element 266 are arranged in alignment. Thus, to avoid unwanted collapse of the guide rail segment 261, a fixing element 264, which in each case is designed as a spring pin, can be inserted into each of the aligned holes 262a, 265b; 263a, 266b.

[0201] 15 shows a cross-sectional top view of sliding stanchion body 120a of sliding stanchion 120, in which the top cross-section of sliding stanchion carriage 250 is visible, and two load-bearing rollers 250a of sliding stanchion carriage 250 are visible, with their running surfaces 250c resting on guide rails 260. Guide rails 260 are laterally connected to the wall of bed 150 of utility vehicle 110, and guide rails 260 extend longitudinally of bed 150. Furthermore, sliding stanchion carriage 250 is connected to sliding stanchion body 120a by rivets 500.

[0202] The sliding stanchion body 120a has an omega-shaped profile 121 in the middle, from which a first V-shaped profile portion 122 extends laterally in the longitudinal direction, from which a second V-shaped profile portion 123 extends laterally on the opposite side, the first V-shaped opening 124 of the first V-shaped profile portion 122 and the second V-shaped opening 125 of the second V-shaped profile portion 123 being oriented toward each other, and the first V-shaped profile portion 122 and the second V-shaped profile portion 123 being positioned away from the cargo bed.

[0203] Furthermore, the sliding stanchion body 120a is symmetrically formed along the longitudinal bisecting plane E', and the sliding stanchion body 120a has a guide element 300 formed as a bend 310 having a radius R' on both sides in the direction of movement x, which element extends from the lower end 120c to the upper end 120b of the sliding stanchion body 120a. Furthermore, the guide element 300 of the sliding stanchion body 120a forms an angle W' with the loading platform 150.

[0204] The running surface 250c of the load-bearing roller 250a is disposed between two protruding collars 250d, and the collars 250d of the load-bearing rollers 250a each surround the guide rail 260 from the sides, so that when a force acts on the sliding stanchion 120 perpendicular to the longitudinal axis of the guide rail 260, there is no possibility that the load-bearing roller 250a of the sliding stanchion carriage 250 will slide laterally and deviate from the guide rail 260, i.e., derail.

[0205] 16 shows a perspective view of the inner surface 350a of the tarpaulin carriage 350, with the load-bearing rollers 351 of the tarpaulin carriage 350 resting on the guide rails 260. The tarpaulin carriage 350 includes a first clamping element 352 and a second clamping element 353, each of which is detachably connected to the tarpaulin carriage 350 by a screw 501. The first clamping element 352 and the second clamping element 353 are formed as flat pieces made of steel material with a rectangular cross-section. The first clamping element 352 and the second clamping element 353 each have a wide side and a narrow side, with the wide side of the first clamping element 352 or the wide side of the second clamping element 353 being arranged parallel to the inner surface 350a of the tarpaulin carriage 350. A strap 290, designated as a tensile reinforcement 280 and represented by a dashed line, is frictionally connected by clamping between the inner surface 350a of the tarpaulin carriage 350 and the first clamping element 352 or the second clamping element 353.

[0206] FIG. 17 shows a perspective view of the lower end 120c of the sliding stanchion 120 with the connected sliding stanchion carriage 250, with the stop body 270 protruding from the sliding stanchion body 120a and aligned in a direction toward the bed 150 of the utility vehicle 110.

[0207] The stop body 270 is formed as a U-shaped flat piece made from steel material having a base 270a connecting first and second leg portions 270b, 270c, which are riveted to the sliding stanchion body 120a, with the base 270a of the stop body 270 projecting downwardly from the sliding stanchion body 120a such that the stop body 270 is positioned perpendicular to the cargo bed 150. Here, the first and second leg portions 270b, 270c of the stop body 270 are each represented by dashed lines.

[0208] Furthermore, an end stop body 271 is disposed between the load-bearing roller 250a of the sliding stanchion carriage 250 and the stop body 270. The end stop body 271 is formed as a flat piece of steel material having a rectangular cross-section, with the end stop body 271 having a wide side and a narrow side, and the end stop body 271 is disposed parallel to the stop body 270. In addition, the end stop body 271 has a first end face 271a and an opposite second end face 271b, which are V-chamfered such that the first end face 271a and the second end face 271b are formed in the shape of a cutting edge, respectively. This facilitates threading of the end stop body 271 between the load-bearing roller 250a of the sliding stanchion carriage 250 and the stop body 270 when the sliding stanchion 120 is displaced. When the side tarpaulin 90 is fully closed, the position of the end stop body 271 in one area of ​​the loading platform 150 corresponds to the end position of the sliding stanchion 120 assigned to the end stop body 271.

[0209] In the final ready-to-drive position, the sliding stanchion 120 is therefore very well protected from the resulting horizontal forces which extend approximately perpendicular to the longitudinal direction of the loading platform 150 and which act on the inner side surface 121 of the sliding stanchion 120. When these forces act on the inner side surface 121 of the sliding stanchion 120, the stop body 270 strikes the end stop body 271, in particular so that the load-bearing roller 250a of the sliding stanchion carriage 250 is not damaged.

[0210] FIG. 18 shows a side view of the sliding stanchion body 120a and sliding stanchion carriage 250 of the sliding stanchion 120, which includes two upper load-bearing rollers 250a arranged in series and two opposing lower counter rollers 250b arranged in series, where the upper load-bearing rollers 250a and the lower counter rollers 250b are identical.

[0211] The guide rail 260 is disposed between the upper load-bearing roller 250a and the lower counter roller 250b and is connected to the bed 150 of the utility vehicle 110 by a threaded connection. A first clamping jaw 272 and a second clamping jaw 273 are disposed between the guide rail 260 and the bed 150, and these jaws clamp the end stop body 271, which is then fixedly connected in this way to the guide rail 260 or the bed 150. In this respect, the end stop body 271 is disposed between the first clamping jaw 272 and the second clamping jaw 273.

[0212] Additionally, the loading platform 150, the first clamping jaw 272, the second clamping jaw 273, the end stop body 271, and the guide rail 260 each have at least one hole. The loading platform 150, the first clamping jaw 272, the second clamping jaw 273, the end stop body 271, and the guide rail 260 are positioned such that the holes are aligned with one another so that screws 501 can be inserted into the holes to connect the loading platform 150, the first clamping jaw 272, the second clamping jaw 273, the end stop body 271, and the guide rail 260 to one another via a threaded connection.

[0213] Additionally, the stop body 270 of the sliding stanchion 120 can be seen, which is positioned between the end stop body 271 and the loading platform 150 and projects downwardly from the sliding stanchion body 120a towards the first clamping jaw 272.

[0214] FIG. 19 shows a schematic rear perspective view of an alternative stanchion hanging device 130 for the sliding stanchion 120, which is connected to the upper end 120b of the sliding stanchion body 120a of the sliding stanchion 120 by four threaded connections with screws 501.

[0215] The stanchion hanging device 130 comprises an elongated stanchion hanging device body 131 designed as a flat piece, from which a first tab 132 and a second tab 133 extend downwards in the same direction towards the sliding stanchion body 120a. The first tab 132 and the second tab 133 are represented by dashed lines.

[0216] Furthermore, the stanchion hanging device body 131, the first tab 132, and the second tab 133 are made integrally from a steel sheet and are manufactured by a laser cutting process. Furthermore, the stanchion hanging device body 131 has a wide side 131a and a narrow side 131b, and the wide side 131a of the stanchion hanging device body 131 is arranged parallel to the sliding stanchion body 120a. Furthermore, the stanchion hanging device 130 is designed to be mirror-symmetrical with respect to the central longitudinal bisector E' of the sliding stanchion body 120a of the sliding stanchion 120.

[0217] The first tab 132 and the second tab 133 of the stanchion hanging device 130 are positioned in a clamping manner within the sliding stanchion body 120a, and the fastening of the stanchion hanging device 130 to the sliding stanchion body 120a will be described in more detail below with reference to FIG. 20.

[0218] The stanchion hanging device 130 here has six vertical twin load-bearing rollers 330 arranged in series, one after the other, along the stanchion hanging device body 131, and in each case the load-bearing rollers 330a; 330b of each twin load-bearing roller 330 are arranged on the wide side 131a of the stanchion hanging device body 131 so that the stanchion hanging device body 131 is designed as a partition wall arranged between the first load-bearing roller 330a and the second load-bearing roller 330b of the corresponding twin load-bearing roller 330.

[0219] The stanchion hanging device body 131 has a first end 134 and an opposite second end 135 in the longitudinal direction, and horizontal guide rollers 340 are arranged at the first end 134 and the second end 135 of the stanchion hanging device body 131, in each case in the direction of movement of the sliding stanchion 120. In this respect, all the twin load-bearing rollers 330 are arranged between the two horizontal guide rollers 340, and the two guide rollers 340 are further fixed to the corresponding pins by locking pins 341, respectively.

[0220] Furthermore, the stanchion suspension device 130 includes four so-called wear blocks 600. When the side tarpaulin 90 is closed during movement of the utility vehicle 110, vibrations and the weight of the sliding stanchion 120 cause the load-bearing rollers 330a, 330b of the twin load-bearing rollers 330 to penetrate the running surface of the first chamber 140a of the longitudinal beam 140, which is made of aluminum.

[0221] Over time, this causes point-like depressions in the running surface of the longitudinal beam 140. In order to prevent the load-bearing rollers 330a; 330b of the twin load-bearing roller 330 from further penetrating into the running surface, so-called wear blocks 600 are fastened to the stanchion suspension device body 131 of the stanchion suspension device 130 by means of a threaded connection with screws 501. As a result, starting from a defined depression depth of, for example, 1 mm, the wear blocks 600 rest with their undersides on the running surface of the longitudinal beam 140, thus preventing the load-bearing rollers 330a; 330b of the twin load-bearing roller 330 from further progressively penetrating into the running surface. The wear blocks 600 therefore have the function of bearing or supporting the load-bearing rollers 330a; 330b of the twin load-bearing roller 330 during the moving operation.

[0222] Each wear block 600 is disposed between the two first load-bearing rollers 330 a of the corresponding twin load-bearing roller 330 and / or between the two second load-bearing rollers 330 b of the corresponding twin load-bearing roller 330 .

[0223] Furthermore, the wear blocks 600 are made of plastic, so that they can be cost-effectively manufactured, preferably by an injection molding process. However, the wear blocks 600 can also be made of a steel material. The wear blocks 600 are each rectangular parallelepiped, with the wide sides of the wear blocks 600 aligned longitudinally parallel to the stanchion hanger body 131.

[0224] Figure 20 shows a cross-sectional view of the stanchion hanging device 130 taken along line XX-XX of Figure 19. In this regard, the first tab 132 of the stanchion hanging device 130 can be seen, which extends downward from the stanchion hanging device body 131 towards the sliding stanchion body 120a of the sliding stanchion 120.

[0225] Furthermore, the first tab 132 is connected to the sliding stanchion body 120a by a threaded connection with the screw 501. Therefore, the tab 132 is arranged parallel to and between the double clamping plate including the first clamping plate 700 and the second clamping plate 701 and the third clamping plate 702.

[0226] The sliding stanchion body 120a, the first fastening plate 700, the second fastening plate 701, and the tab 132 each have an opening 703 into which a screw 501 having an externally threaded portion can be inserted in a direction transverse to the longitudinal direction of the sliding stanchion body 120a. The third fastening plate 702 has an internally threaded hole 704 so that the screw 501 is mounted by its externally threaded portion within the internally threaded hole 704 in a friction-locking and interlocking manner in that the external threads of the screw 501 engage with the internal threads of the internally threaded hole 704. This causes the opening 703 and the corresponding internally threaded hole 704 to be aligned.

[0227] Accordingly, the second tab 133 is attached to the sliding stanchion body 120a following the first tab 132. Here, the first tab 132 and the second tab 133 each have two screws 501 for stable fastening to the sliding stanchion body 120a, and the first tab 132 and the second tab 133 each are connected to the sliding stanchion body 120a by tightening.

[0228] The present invention has been described above based on several exemplary embodiments, and it is understood that the features of the exemplary embodiments may also be combined individually or in their entirety, and that these combinations are hereby expressly described as part of the disclosure of this application.
