Description

[0001] Sled and opening side tarpaulin wall system

[0002] The invention relates to a slide, in particular for use in an openable side tarpaulin wall system for a commercial vehicle according to the preamble of an independent claim, and to an openable side tarpaulin wall system for a commercial vehicle.

[0003] In practice, a wide variety of solutions and configurations are known for side curtain wall systems for commercial vehicles. Commercial vehicles, such as trucks, trailers, and semi-trailers, primarily serve to transport goods and merchandise on public roads. For this purpose, commercial vehicles include a cargo area designed to hold the goods and merchandise being transported. This cargo area is typically equipped with a side curtain wall system along its sides.

[0004] Side tarpaulin wall systems for commercial vehicles are known from practical experience, in which a side tarpaulin or strap is attached to an outer guide surface of a slide by means of rivets, with a backing plate serving as a base for the rivet head. A disadvantage of this design is that the dynamic loads on the side tarpaulin are transferred into the hole created by the rivet, and due to the resulting stress concentration, the strap or tarpaulin material quickly tears and becomes unusable. Furthermore, the strap or tarpaulin material cannot be easily loosened and retensioned after relaxation has occurred.

[0005] The side curtain wall system of a commercial vehicle primarily serves to protect cargo from rain, dirt, weather, and other lateral influences. Furthermore, the side curtain wall system must ensure cargo security, particularly during travel, for example, when cornering or during emergency braking. This means the system must always be able to absorb a defined horizontal force, such as that exerted by cargo shifting within the cargo area. These forces act primarily on sliding carriages connected to a side curtain of the side curtain wall system, which can be moved along a guide rail. A disadvantage is that existing carriages are not capable of absorbing or transmitting sufficiently high forces.

The object of the invention is to provide a slide or an openable side tarpaulin wall system that can reliably and safely absorb horizontal forces.

[0011] This problem is solved according to the invention by a slide with the features of an independent claim or by an openable side panel wall system with the features of an independent claim.

[0012] According to one aspect of the invention, a slide for use in an openable side tarpaulin wall system for a commercial vehicle is provided, comprising a plate-shaped body with an outer guide surface and an inner guide surface, wherein the body has a narrow side perpendicular to the outer and inner guide surfaces, a mounting plate for attaching a belt, and a roller with a horizontal axis of rotation, wherein the mounting plate and the roller are arranged on the inner guide surface of the body, wherein the body has a recess for receiving the belt, the recess having a horizontal deflecting edge, and wherein the recess is arranged below the mounting plate. The slide is characterized in that the recess is arranged between the mounting plate and the roller.Advantageously, the belt does not affect the roller's movement, thus preventing the belt from becoming entangled with the roller and ensuring a reliable carriage. Furthermore, connecting the belt to the carriage is simple and intuitive. Due to the advantageous arrangement of the recess, the belt can be connected to the carriage in such a way that only minimal torques from the belt act on the carriage. Consequently, a carriage that is particularly resistant to increased horizontal forces is advantageously created, ensuring reliability, safety, and durability. The recess is expediently designed as an elongated slot to accommodate the full width of the belt.The advantage of the design is that the full width of the belt is arranged in the holder, so that on the one hand the belt material is protected, and on the other hand a uniform force distribution from the belt to the carriage is achieved without any point-like force acting, thus ensuring an increased product lifespan of the belt.

[0013] Preferably, the horizontal deflection edge of the recess has a rounded shape with a radius. Advantageously, the rounding of the deflection edge prevents, for example, a sharp edge from cutting into the belt and thus damaging it.

[0014] Advantageously, the distance from the horizontal deflection edge to the axis of rotation of the roller is 3 to 15 times, preferably 5 to 10 times, and particularly preferably 7 to 8 times the thickness of the narrow side of the body. Advantageously, the distance from the horizontal deflection edge to the axis of rotation of the roller can be easily calculated as a function of the thickness of the body, so that, for example, with a different slide and a different body thickness, the distance between the deflection edge and the axis of rotation of the roller can be easily determined, thus minimizing the forces acting on the slide from the belt.

[0015] In an advantageous embodiment, the thickness of the narrow side is 3 mm to 20 mm, preferably 4 mm to 12 mm, and particularly preferably 5 mm to 8 mm. Advantageously, the body of the slide is made of a sheet material, for example, steel or an aluminum alloy, with the thickness being advantageously thin so that the slide is designed to save installation space.

[0016] Preferably, the thickness of the narrow side is constant. A constant body thickness particularly facilitates simple and cost-effective manufacturing. Furthermore, the slide is compact and space-saving. Advantageously, the roller has a maximum outer radius around the axis of rotation, wherein the distance from the horizontal deflection edge to the axis of rotation of the roller is 1 to 5 times, preferably 1.2 to 2.5 times, more preferably 1.3 to 1.8 times, and particularly preferably 1.5 times the maximum outer radius of the roller. Advantageously, the distance from the horizontal deflection edge to the axis of rotation of the roller can be easily calculated as a function of the maximum outer radius of the roller, so that, for example,With a different sled, a different roller, and a different outer radius, the distance between the deflection edge and the axis of rotation of the roller can be determined in a simple way, so that small forces from the belt act on the sled.

[0017] According to one aspect of the invention, a slide for use in an openable side tarpaulin wall system for a commercial vehicle is provided, comprising a plate-shaped body with an outer guide surface and an inner guide surface, wherein the body has a narrow side perpendicular to the outer and inner guide surfaces, a mounting plate for attaching a belt, and at least two rollers, each with a horizontal axis of rotation, wherein the mounting plate and the two rollers are arranged on the inner guide surface of the body, wherein the body has a recess for receiving the belt, the recess having a horizontal deflecting edge, and wherein the recess is arranged below the mounting plate. The slide is characterized in that the recess of the body is arranged centrally between the two rollers.Advantageously, the torque generated by the belt, which acts on the upper rollers, is minimized, allowing horizontal forces acting on the carriage to be effectively dissipated.

[0018] Preferably, a first counter-roller with a horizontal first axis of rotation is arranged on the inner guide surface below the roller. Advantageously, a first counter-roller arranged below the roller increases the stability of the slide. Preferably, a second counter-roller with a horizontal second axis of rotation is arranged on the inner guide surface below the roller. Advantageously, a first and a second counter-roller arranged below the roller increase the stability of the slide, wherein the roller, the first counter-roller, and the second counter-roller are arranged in one plane, resulting in a compact, space-saving, and stable slide design.

[0019] Preferably, the roller, the first counter-roller, and the second counter-roller are arranged in a triangular formation with respect to their pivot points. Advantageously, this secures the carriage against pivoting and / or tilting in a displacement direction or in a direction transverse to the displacement direction, ensuring that the carriage is always correctly positioned upright in a guide rail.

[0020] In an advantageous embodiment, the triangular formation is designed as an isosceles triangle comprising a base and an apex, wherein the connection between the pivot points of the first and second counter-rollers forms the base of the isosceles triangle, such that the pivot point of the roller is the apex of the isosceles triangle. This results in a compact, space-saving, and very stable sled.

[0021] In an alternative embodiment, the recess is arranged below the first counter roller and / or below the second counter roller. Advantageously, different connection points of the belt to the carriage are provided, whereby the forces emanating from the belt and acting on the carriage can be individually adjusted.

[0022] According to a further aspect of the invention, a slide for use in an openable side tarpaulin wall system for a commercial vehicle is provided, comprising a plate-shaped body with an outer guide surface and an inner guide surface, wherein the body has a narrow side perpendicular to the outer guide surface and the inner guide surface with a thickness, a mounting plate for attaching a belt, and a roller with a horizontal axis of rotation, wherein the mounting plate and the roller are arranged on the inner guide surface of the body, wherein the body has a recess for receiving the belt, wherein the recess has a horizontal deflecting edge, wherein the recess is arranged below the mounting plate, and wherein a first counter roller with a horizontal first axis of rotation is arranged below the roller on the inner guide surface.A second counter-roller with a horizontal second axis of rotation is arranged below the roller on the inner guide surface. The carriage is characterized by the fact that the carriage body has a first horizontal elongated recess and a second horizontal elongated recess between the roller and the first counter-roller and the second counter-roller, respectively. Advantageously, the belt is connected to the carriage essentially at the same level with a guide rail for the first time, so that forces transmitted from the belt to the carriage are distributed evenly to the roller, the first counter-roller, and the second counter-roller, resulting in a virtually identical and uniform force acting on each roller. The carriage is thus able to efficiently absorb and transmit horizontal forces.

[0023] The first recess has a first deflecting edge formed with a rounded shape, wherein the distance from the axis of rotation of the roller to the first deflecting edge of the first recess is 1 to 5 times, preferably 1 to 3 times, and particularly preferably 1.8 times the maximum outer radius of the roller, wherein the second recess has a lower edge formed with a rounded shape, wherein the distance from the axis of rotation of the roller to the lower edge of the second recess is 1 to 3 times, preferably 1 to 2 times, and particularly preferably 1.25 times the maximum outer radius of the roller.

[0024] In a preferred embodiment, the roller and / or the first counter-roller and / or the second counter-roller each have a central running surface, and each roller and / or the first counter-roller and / or the second counter-roller have a radially projecting collar on both sides of the central running surface. The radially projecting collars prevent a roller from disintegrating from a guide rail, particularly in a direction transverse to the displacement direction of the slide, so that increased horizontal forces can be absorbed or transmitted via the rollers.

[0025] Preferably, a deflection plate is arranged above the mounting plate. The deflection plate offers the advantage that the belt can be wrapped around it, thus providing a kind of strain relief. Furthermore, the belt can be fixed to the inner guide surface of the carriage body via the deflection plate, allowing for easy tensioning of the belt. The mounting plate and the deflection plate are advantageously attachable and detachable via a screw connection.

[0026] Preferably, a vertical plane of mirror symmetry is arranged along the axis of rotation of the roller. Because the slide is symmetrical, manufacturing is simple and cost-effective. Furthermore, the forces acting on the slide are distributed and transmitted evenly, resulting in safe and reliable operation.

[0027] According to one aspect of the invention, an openable side tarpaulin wall system for a commercial vehicle is provided, comprising a tarpaulin segment which at least partially closes a side opening of the commercial vehicle and which is suspended via at least one tarpaulin suspension device which is displaceable along a longitudinal beam supported against a loading platform and / or against a frame, and at least one slide which is displaceable longitudinally along a guide rail associated with the loading platform and / or the frame, wherein the tarpaulin segment has at least one strap which is connected to the slide, wherein the slide comprises a body with an outer guide surface, an inner guide surface and a mounting plate for attaching the strap, wherein the strap of the tarpaulin segment rests on the outer guide surface, and wherein the strap is guided through a recess in the body.and wherein the belt is clamped between the inner guide surface and the mounting plate. The openable side tarpaulin wall system is characterized in that the slide is designed as a slide according to the invention. Advantageously, a simple, quick, and intuitive connection of the belt to the slide within an openable side tarpaulin wall system is provided, whereby the tarpaulin segment can safely and reliably transmit horizontal forces to the respective slides, and the slides can safely and reliably absorb these forces, thereby preventing, in particular, the slide from jamming with the guide rail.

[0028] Advantageously, the slide comprises a deflection plate with a first side and a second side, wherein the deflection plate is arranged on the inner guide surface at a distance from the mounting plate, the first side of the deflection plate facing the inner guide surface and the second side of the deflection plate facing away from the inner guide surface, and wherein the belt is placed around the deflection plate so that the belt rests on the second side of the deflection plate. The deflection plate advantageously serves as a strain relief for the belt, and the deflection plate can also be mounted on the inner guide surface of the slide body so that the belt can also be fixed to the body via the deflection plate, e.g., for tensioning the belt.

[0029] Preferably, the belt, which is wrapped around the deflection plate, is guided through a gap between the deflection plate and the mounting plate, wherein the belt is guided between a first belt section and the mounting plate, and wherein the first belt section and a second belt section are clamped between the inner guide surface and the mounting plate. Advantageously, reliable clamping of the belt is achieved if a first belt section and a second belt section are clamped in a sandwich arrangement between the inner guide surface of the carriage body and the mounting plate, whereby increased friction is advantageously achieved, thus ensuring a stable, force-fit connection.

[0030] In an advantageous embodiment, a sliding post with a stake carriage is arranged between the longitudinal beam and the guide rail. The stake carriage is movable along the guide rail, and at least one strap of the tarpaulin segment is connected to the stake carriage. Sliding posts are particularly advantageous for relatively long longitudinal beams, as they prevent deflection of the longitudinal beam due to the weight of a roof, ensuring that the longitudinal beam of the openable side tarpaulin wall system is always correctly aligned. Furthermore, sliding posts can also absorb horizontal forces, thus relieving stress on the tarpaulin segments, the tarpaulin suspension devices, and the carriages.

[0031] Advantageously, the stake slide is designed as a slide according to the invention. A strap of a tarpaulin segment can also be advantageously attached to a stake slide, so that the stake slide can absorb and transmit horizontal forces effectively, thereby ensuring increased product durability of the stake slide.

[0032] Further advantages, developments and features of the invention will become apparent from the following description of a preferred embodiment and from the dependent claims.

[0033] The invention is explained in more detail below with reference to the accompanying drawings and a preferred embodiment of the invention.

[0034] Fig. 1 shows a schematic side view of a commercial vehicle of an exemplary embodiment.

[0035] Fig. 2 shows a perspective view of the slide according to the invention.

[0036] Fig. 3 shows a rear view of the sled.

[0037] Fig. 4 shows a sectional view from Fig. 3.

[0038] Fig. 5 shows another embodiment.

[0039] Fig. 6 shows a detail view from Fig. 5.

[0040] Fig. 7 shows another embodiment.

[0041] Fig. 1 shows in a schematic side view an openable side tarpaulin wall system 1 for a commercial vehicle V, which is shown in dotted lines, wherein the commercial vehicle V, comprising a tractor unit and a semi-trailer, is by way of example a semi-trailer truck.

[0042] The openable side tarpaulin wall system 1 comprises a tarpaulin segment 2 designed as a foldable tarpaulin, which at least partially closes a lateral opening s of the commercial vehicle V and which is suspended via several tarpaulin suspension devices 3, which are movable along a longitudinal beam 6 supported against a loading platform 4.

[0043] Furthermore, the openable side tarpaulin wall system 1 comprises several slides 10 which can be displaced in the longitudinal direction L along a guide rail 7 assigned to the loading platform 4, wherein the tarpaulin segment 2 has at least one strap G which strap G is connected to at least one of the slides 10, the strap G being shown from Fig. 2 onwards.

[0044] Furthermore, Fig. 1 shows two tarpaulin segments 2 which are connected to each other via a sliding stake 8, wherein the sliding stake 8 can be moved along the guide rail 7 via a stake slide 9.

[0045] Fig. 2 shows a perspective view of an outer guide surface 12 of the slide 10. The slide comprises a plate-shaped body 11 with the outer guide surface 12 and an inner guide surface 13 parallel to it, the body 11 having a narrow side 14 perpendicular to both the outer guide surface 12 and the inner guide surface 13, with a constant thickness t. Furthermore, the slide 10 comprises a horizontal, elongated recess 17 with a horizontal deflecting edge 18, the belt G passing through the recess 17 with its full width w, the belt G bearing against the rounded deflecting edge 18 of the recess 17.

[0046] Fig. 3 shows a view of the inner guide surface 13 of the body 11 of the slide 10. It can be seen that the slide 10 comprises, above the elongated recess 17, a mounting plate 15 for fastening the belt G and a deflecting plate 23 arranged above the mounting plate 15, with a first side 23a and a second side 23b, wherein both the mounting plate 15 and the deflecting plate 23 are arranged on the inner guide surface 13, with the first side 23a of the deflecting plate 23 facing the inner guide surface 13.

[0047] Furthermore, in this embodiment, the slide 10 has a roller 16 with a horizontal axis of rotation A and a maximum outer radius R, the roller 16 being arranged below the recess 17. The slide 10 also has a first counter-roller 19 arranged below the roller 16 with a horizontal first axis of rotation B, and a second counter-roller 20 arranged below the roller 16 with a horizontal second axis of rotation C. The roller 16, the first counter-roller 19, and the second counter-roller 20 are arranged in a triangular formation with respect to their pivot points A, B, and C. The triangular formation is an isosceles triangle D comprising a base and an apex. The connection between the pivot points B and C of the first counter-roller 19 and the second counter-roller 20 forms the base of the isosceles triangle D, such that the pivot point A of the roller 16 is the apex of the isosceles triangle D.Furthermore, the roller 16, the first counter roller 19, and the second counter roller 20 are arranged on the inner guide surface 13 of the slide 10. In addition, the slide 10 is mirror-symmetrical with respect to a vertical plane of symmetry E, which is arranged in both directions along the axis of rotation A of the roller 16.

[0048] Fig. 4 shows a sectional view IV-IV from Fig. 3, in which it can be seen that the horizontal deflecting edge 18 of the recess 17 has a rounded section with a radius r in order not to damage the belt G which is arranged to rub against the deflecting edge 18. Furthermore, the roller 16 is arranged at a defined distance P from the deflecting edge 18 of the recess 17, wherein the distance P from the horizontal deflecting edge 18 to the axis of rotation A of the roller 16 is approximately 1.5 times the maximum outer radius R of the roller 16.

[0049] Furthermore, the belt G is connected to the carriage 10 in a specific manner. The belt G rests on the outer guide surface 12 of the body 11 of the carriage 10, and is guided through the recess 17 of the body 11 at the curve with radius r of the horizontal deflection edge 18 of the recess 17. The belt G is clamped between the inner guide surface 13 and the mounting plate 15. The belt G is also positioned against the inner guide surface 13 of the body 11, and is wrapped around the deflection plate 23 so that it rests on the second side 23b of the deflection plate 23. The belt G, wrapped around the deflection plate 23, is guided through a gap 24 located between the deflection plate 23 and the mounting plate 15.Here, the belt G is arranged between a first belt section G1 of the belt G and the mounting plate 15, wherein the first belt section G1 of the belt G and a second belt section G2 of the belt G are clamped between the inner guide surface 13 and the mounting plate 15.

[0050] Furthermore, the mounting plate 15 and the deflection plate 23 can be attached and fastened to the body 11 of the carriage 10 by means of detachable fasteners, for example, screws. Additionally, the roller 16, the first counter roller 19, and the second counter roller 20 each have a central running surface 21, wherein the roller 16, the first counter roller 19, and the second counter roller 20 each have a radially projecting collar 22 on both sides of the central running surface 21, so that the roller 16, the first counter roller 19, and the second counter roller 20 can reliably absorb or transmit horizontal forces acting on the carriage 10.

[0051] Fig. 5 shows a sectional view of another embodiment of a slide 10'. The difference compared to the previous slide 10 is that the body 11' of the slide 10' now has two further parallel recesses 17', 17" between the roller 16 and the first counter roller 19 and the second counter roller 20, respectively. A web 26 is arranged between the two recesses 17', 17"; a detailed view of this is shown in Fig. 6.

[0052] Here, the lower first recess 17' is designed as a horizontal, elongated recess 17' which can accommodate the full width w of the belt G, which is shown at least partially with dashed lines. Furthermore, the upper second recess 17" is designed as a horizontal, elongated recess 17" which can also accommodate the full width w of the belt G. The first recess 17' further comprises a first deflection edge 18' rounded with a radius r', and the second recess 17" further comprises a second lower edge 18" rounded with a radius r". Here, a distance P' from the axis of rotation A of the roller 16 to the deflection edge 18' of the first recess 17' is approximately 1.8 times the outer diameter R of the roller 16, and a distance Q from the axis of rotation A of the roller 16 to the lower edge 18" of the second recess 17" is approximately 1.25 times the outer diameter R of the roller 16.

[0053] To connect the belt G to the carriage 10', the belt G must first be inserted into the first recess 17' while resting against the outer guide surface 12 of the body 11'. The belt G then rests, at least partially, against the inner guide surface 13, where it is immediately guided outwards into the second recess 17". Once the belt G has passed through the second recess 17", it is guided upwards along the outer guide surface 12 of the body 11', where it is inserted into the recess 17 as before. Finally, the belt G is secured as described above using the mounting plate 15 and the deflection plate 23.Advantageously, due to the arrangement of the belt G in the first recess 17', a particularly low torque is transmitted to the roller 16 and to the first counter roller 19 as well as to the second counter roller 20, whereby acting forces are transmitted evenly to the roller 16, to the first counter roller 19 as well as to the second counter roller 20.

[0054] Furthermore, the carriage 10, 10' can be used as a stake carriage in which a first carriage 10, 10' and an opposing second carriage 10, 10' are integrally connected via an identical extended body, with a sliding stake vertically arranged in the center of the stake carriage. The first carriage 10, 10' is thus located on one side of the sliding stake, and the second carriage 10, 10' is located on the other side. Consequently, the stake carriage can be rigidly connected to a strap G on each side. The stake carriage can also be moved along the guide rail 7.

[0055] Fig. 7 schematically shows another embodiment of a slide 100. The slide 100 comprises a plate-shaped body 110 with an outer guide surface 120 and an inner guide surface 130, with the view of the inner guide surface 130 of the body 110 being shown. The difference from the previous embodiments is that two upper rollers 160 are now rotatably attached to the body 110, with a recess 170 in the body 110 for receiving and deflecting a belt G being arranged centrally between the two rollers 160. A counter roller 190, 200 is rotatably arranged below each of the rollers 160, so that the slide 100 can also be moved along a guide rail 7. The recess 170 also has a deflecting edge 180 rounded with a radius r1, so that damage to the belt G is prevented.Furthermore, the belt G is simply fixed to the body 110 by means of a mounting plate 150 and fasteners 250. Advantageously, this minimizes the torque generated by the belt G acting on the upper rollers 160, allowing horizontal forces acting on the carriage 100 to be effectively dissipated.

[0056] The invention works as follows:

[0057] The carriage 11 is arranged to be displaceable in the longitudinal direction L on the guide rail 7 of an openable side tarpaulin wall system 1 such that the roller 16 is assigned to an upper narrow side of the guide rail 7, and the first counter roller 19 and the second counter roller 20 are assigned to opposite lower narrow sides of the guide rail 7. To connect the tarpaulin segment 2 with its strap G to the carriage 10, the strap G is attached to the carriage 10 as described above, with the strap G being tensioned in a conventional manner known to a person skilled in the art. Once the tarpaulin segment 2 is connected to the carriage 10, the tarpaulin segment 2 can be easily and simply displaced along the guide rail 7 with the aid of the carriage 10 when opening and closing the tarpaulin segment 2, so that a defined fold of the tarpaulin segment can be repeated without fluttering.

[0058] Due to the configuration of the slide 10, horizontal forces acting directly and / or indirectly on the tarpaulin segment 2 and on the slide 10 can advantageously be reliably and safely absorbed and transmitted without causing damage to the tarpaulin segment 2 or the slide 10. These horizontal forces are all forces that have at least a partial horizontal component. These horizontal forces can occur, for example, when the commercial vehicle V is cornering, such as when a load located in the cargo area of ​​the commercial vehicle V presses against the inside of the tarpaulin segment 2.

[0059] Advantageously, the belt G connected to the carriage 10 generates only a small torque with respect to the roller 16, the first counter roller 19 and the second counter roller 20, due to the small distance P between the axis of rotation A of the roller 16 and the deflecting edge 18 of the recess 17, so that the forces emanating from the belt G and acting on the carriage 10 can be well dissipated.

[0060] The invention has been explained above using an exemplary embodiment in which the carriage is associated with the guide rail. It is understood that the carriage can also be attached to a longitudinal beam in a displaceable manner.

[0061] The invention has been explained above using an exemplary embodiment in which a strap can be connected to the carriage. It is understood that other lashing devices, e.g., a rope, can also be connected to the carriage instead of a strap.

[0062] The invention has been explained above using an exemplary embodiment in which the carriage has rollers. It is understood that sliding elements or a combination of rollers and sliding elements can also be attached to the carriage instead of rollers.

[0063] The invention has been explained above with reference to an exemplary embodiment in which the deflecting edge 18, 18' is designed as a rounded longitudinal edge, preferably the upper longitudinal edge of an elongated hole 17, 17'. It is understood that instead of the rounded longitudinal edge, a roller or the like can also be provided, which is rotatably mounted in the body, thereby facilitating the guidance of the belt. In particular, the roller can have a longitudinal groove into which the belt can be clamped and thus guided in a defined manner around the deflecting edge. Especially in the embodiment where the belt is guided through multiple recesses in the body, this can facilitate threading of the belt. Furthermore, a common recess in which the roller is subsequently arranged can be manufactured more easily, since a gap or web required for strength reasons can be omitted. The roller is preferably rotatably mounted on the body.For practical purposes, the roller should not protrude more than 10 mm from the outer guide surface, so that no significantly larger overhang is created than, for example, by the rivet heads of the rollers or the counter rollers.

[0064] The invention has been explained above with reference to an exemplary embodiment in which the body has a single roller designed as a support roller and two counter rollers. It is understood that the body can also have two rollers designed as support rollers, either with only one counter roller or also with two counter rollers, wherein the distance between the adjacent support rollers is preferably dimensioned such that the belt can be guided past the rivet heads of the rollers along the outer guide surface. In the case of two support rollers, the recess having the deflecting edge can be arranged such that the deflecting edge lies almost in the horizontal plane spanned by the two axes A of the two rollers, thus ensuring that only small moments are introduced from the belt into the carriage or its rollers.
