Description

Domaine Technique

[0001] The present invention relates to a longitudinal partitioning device for a refrigerated body, in particular for a refrigerated body of a motor vehicle or a motor vehicle trailer. The invention also relates to a trailer for a motor vehicle, in particular for a truck, comprising a refrigerated body equipped with at least one partitioning device. Arrière-plan technique

[0002] Partitioning devices for refrigerated vehicles are known which make it possible to delimit within the same refrigerated body, whether it is a refrigerated body placed on a truck or on a semi-trailer, separate zones, which can possibly be directed under different temperatures. A partitioning device typically has a movable partition between a vertical position in the body and a raised position in which the partition is, for example, folded upwards against a ceiling of the refrigerated body.

[0003] Document EP-3.825.180-A1 describes an improved partitioning device with numerous advantages. In particular, the partitioning partition has, at an upper edge of the partition, a mechanism for anchoring the partition in a multitude of longitudinal positions in the bodywork. Furthermore, this document describes a partitioning device in which the partition comprises two transversely juxtaposed panels, each of which can be retracted independently of the other by pivoting around the upper transverse retraction axis between a vertical service position and a raised position.

[0004] Furthermore, lashing bars are known for forming, in the loading volume of a truck body or a truck trailer, a solid support for securing loads in the loading volume, and / or for blocking the movement of loads in the loading volume in the longitudinal direction. A lashing bar is intended to be removably fixed in a longitudinal position across the loading volume. For this purpose, the lashing bar has two lashing ends which are each provided with a lashing member on a side wall of the rigid body. It is known to provide the two opposite internal side walls of a rigid body each with a longitudinal profile comprising a multitude of lashing means complementary to the lashing members of the lashing bar, distributed over the length of the rail.Such facing profiles allow a lashing bar to be removably fixed in different longitudinal positions in the loading volume, depending on the load to be secured. Generally, to unload a trailer, it is necessary to unhook the lashing bar. At the end of unloading, the lashing bar may be forgotten on the loading dock. EP-3,699,027, US-4,880,342, US-2,715,040 and US-5,265,993 describe systems according to the prior art.

[0005] The object of the invention is to provide an improved partitioning device, which facilitates the work of loading and unloading a refrigerated vehicle, to promote both the safety of loading and compliance with the temperature conditions for transporting the goods. Exposé de l'invention

[0006] The invention provides a longitudinal partitioning device for a refrigerated body, of the type comprising at least one partitioning partition having, at an upper edge of the partition, a mechanism for anchoring the partition in a multitude of longitudinal positions in the body, and the partition being retractable by pivoting the partition around an upper transverse retraction axis between a vertical service position and a raised position.

[0007] The device comprises a lashing bar which is in one or more parts, and which is fixed to the partition by a tilting mechanism which allows the lashing bar to be moved between a storage position and a lashing position relative to the partition. The lashing bar is thus always available. Furthermore, by being fixed to the partition, it ensures, in the lashing position, lashing of the partition relative to its upper transverse retraction axis.

[0008] In some embodiments, the tilting mechanism determines a movement of the lashing bar, between its lashing and storage positions, which is parallel to a general plane of the partition. This allows for minimal bulkhead space for the assembly, and easy manipulation of the lashing bar between its storage and lashing positions.

[0009] In some embodiments, in the stowed position, the lashing bar is horizontal, and in the stored position, the lashing bar is inclined relative to the horizontal by a storage angle that is in the range of 15 degrees to 90 degrees. This allows the lashing bar, in the stored position, not to protrude transversely from the partition. The space requirement is therefore reduced.

[0010] In some embodiments, the lashing bar comprises two lashing ends which are each provided with a lashing member on a side wall of the refrigerated body. Securing on the walls allows the bar to form a solid lashing point for the cargo, and on the other hand, the bar is also secured to the partition, it allows the partition to be securely lashed, by blocking any rotation of the partition around its retraction axis.

[0011] In some embodiments, the tilting mechanism comprises a hinge by which the lashing bar is hinged to the partition about an axis of rotation perpendicular to the partition. Such an embodiment is simple and inexpensive to implement.

[0012] In some embodiments, the tilting mechanism includes at least one sliding connection point between the bar and the partition, offset from the axis of rotation of the bar. In some embodiments, the sliding connection point of the tilting mechanism includes a slide in an arc about the axis of rotation and a claw that is retained by the slide in at least one direction in the direction perpendicular to the partition and that can slide in the slide in the arc about the axis of rotation. The slide may be integral with one of the partition and the bar, while the claw may be integral with the other of the partition and the bar.

[0013] In some embodiments, the partition comprises two transversely juxtaposed panels, each of which is independently retractable from one another by pivoting about the transverse upper retraction axis between a vertical service position and a raised position. In such a case, the lashing bar may comprise a first half-bar which is fixed to a first of the two panels by a first tilting mechanism which allows the first half-bar to move between a storage position and a stowed position relative to the first panel, and a second half-bar which is fixed to the second panel by a second tilting mechanism which allows the second half-bar to move between a storage position and a stowed position relative to the second panel.Each half-bar may have a medial end and a lateral end, the lateral end being able to be provided with a lashing member on a side wall of the refrigerated body, the lateral end thus forming a lashing end of the lashing bar. The production of the lashing bar in several parts makes it possible to reduce the weight of each part, which simplifies the retraction maneuvers of the panels around the upper transverse retraction axis. This also allows each part of the bar to be easily included, in the storage position, in the transverse dimensions of the panel in question.

[0014] In some embodiments, the half-bar tilting mechanism determines a movement of the half-bar, between its stowed and stored positions, which is parallel to a general plane of the corresponding panel. This allows for minimal bulk for the assembly, and easy handling of the half-bar between its stored and stowed positions.

[0015] In some embodiments, the half-bar tilting mechanism comprises a hinge by which the half-bar is hinged to the corresponding panel about an axis of rotation perpendicular to the corresponding panel. Such an embodiment is simple and inexpensive to implement.

[0016] In some embodiments, the half-bar tilting mechanism comprises at least one sliding connection point between the half-bar and the corresponding panel of the partition, offset from the axis of rotation of the half-bar. This makes it possible to limit the risk of the half-bar being torn off from the panel. The tilting mechanism may thus comprise a slide in an arc of a circle around the axis of rotation and a claw which is retained by the slide in at least one direction in the direction perpendicular to the panel and which can slide in the slide in the arc of a circle around the axis of rotation, the slide being secured to one of the panel and the half-bar, while the claw is secured to the other of the panel and the half-bar. Such a design is simple and reliable.

[0017] In some embodiments, the half-bar has a center of gravity that is closer to the upper transverse retraction axis when the half-bar is in the storage position than when it is in the stowed position. This makes it possible to simplify the retraction of the corresponding panel.

[0018] In some embodiments, the axis of rotation of the half-bar is offset along the half-bar toward a lateral end of the half-bar.

[0019] In some embodiments, the device comprises means for locking the medial ends of the half-bars in the stowed position, locking the rotation of the half-bars in the stowed position.

[0020] In certain embodiments, the device comprises means for mutually embedding the medial ends of the half-bars in the anchoring position, thus making it possible to produce, at lower cost, a bar in several parts having resistance properties equivalent to those of a single-part bar.

[0021] In certain embodiments, the device comprises a member for returning the half-bar to its storage position, thus allowing it to be given a stable position. The return means can also facilitate the handling of the half-bar, for example if the latter has a center of gravity offset from its axis of rotation.

[0022] In certain embodiments, the joint has laxity along the axis of rotation, making it possible to limit the risk of the bar being torn away from the partition.

[0023] The invention also relates to a refrigerated body comprising at least one partitioning device having at least one of the characteristics stated above. Such a refrigerated body may, for example, be part of a motor vehicle or a motor vehicle trailer.

[0024] The invention also relates to a trailer for a motor vehicle, the trailer comprising a refrigerated body having at least one partitioning device having at least one of the characteristics stated above.

[0027] There figure 1 shows a partitioning device 10 of a refrigerated body 11, in an example in which the refrigerated body is part of a motor vehicle trailer 12.

[0028] In this example, the refrigerated body 11 is that of a semi-trailer 12, intended to be towed by a tractor truck 14. In a known manner, the tractor truck 14 comprises a chassis 16 having at least one front axle 18 and one rear axle 20. The front part carries a cabin 22 housing the driving position of the tractor truck 14. The rear part of the chassis 16, longitudinally behind the cabin 22, comprises a coupling (not visible) of the “fifth wheel” type. The semi-trailer 12 comprises a chassis which comprises one or more rear axles 24, but, being a semi-trailer, no front axle. The front part 26 of the semi-trailer 12 overlaps the rear part of the chassis of the tractor truck 14 and is articulated on the fifth wheel. However, in other examples, the refrigerated body could be placed on the chassis of a rigid truck, or could be integrated into any other type of motor vehicle.

[0029] The refrigerated body 11 delimits a loading volume 28 intended to accommodate goods. This loading volume 28 is generally accessible from a rear face 30 of the semi-trailer, generally equipped with a door, for example a double-leaf door or a roller shutter door. This loading volume 28 is preferably parallelepipedal, with a longitudinal direction which is that of the vehicle, a vertical direction, and a transverse direction perpendicular to the longitudinal and vertical directions. The refrigerated body 11 conventionally comprises a floor 32, preferably horizontal, side walls 34, preferably longitudinal and vertical, and a ceiling 36, also preferably horizontal.Preferably, the side walls 34 are made of isothermal materials so as to define a loading volume thermally insulated from the outside, in which goods can be transported under controlled temperatures. In a known manner, the semi-trailer 12 comprises a refrigeration installation for lowering the temperature inside the loading volume 28 relative to the temperature of the ambient air outside the bodywork 11.

[0030] The partitioning device 10 makes it possible to delimit distinct zones between them, within the loading volume 28 defined by the refrigerated body 11. These distinct zones can be maintained at the same temperature or at different temperatures.

[0031] The partitioning device 10 is a longitudinal partitioning device that makes it possible to separate a front area 38 from a rear area 40 in the loading volume 28 of the refrigerated body 11. To achieve this, the partitioning device 10 comprises at least one partitioning partition 42 having, at an upper edge 44 of the partition 42, an anchoring mechanism 46 for anchoring the partition 42 in a multitude of longitudinal positions in the body 11. The multitude of positions comprises at least two distinct longitudinal positions, and preferably more, with positions distributed over a range of positions that preferably extends over several meters, possibly over more than 80 percent of the length of the loading volume 28. The multitude of positions could consist of an infinite number of contiguous positions, with a continuously adjustable anchoring mechanism.However, in practice, the anchoring mechanism 46 makes it possible to anchor the upper edge 44 in one of a series of several discrete longitudinal positions, distributed, for example at regular intervals, for example intervals of 5 centimeters or of one or more tens of centimeters, over a range of positions which preferably extends over several meters.

[0032] In a known manner, the partitioning partition 42 is retractable by pivoting the partition 42 around an upper transverse retraction axis A46 between a vertical service position (shown in the Figure 1 ), and a raised position (not shown). Preferably, the raised position of the partition 42 is substantially horizontal and substantially attached to the ceiling 36. Preferably, the anchoring mechanism 46 makes it possible to maintain the partition 36 in the raised position. Preferably, the anchoring mechanism 46 makes it possible to maintain the partition 42 in the vertical, service position. Preferably, to effectively separate the separate zones 38, 40 of the loading volume 28 from a thermal point of view, the partitioning partition extends, in the service position, over the entire height of the loading volume 28 in the vertical direction, and over the entire width of the loading volume in the transverse direction. Preferably, the partitioning partition is made of thermally insulating materials.

[0033] In some embodiments, such as the first embodiment illustrated in Figures 2 et 3 , the partition wall 42 comprises a single panel which extends over the entire width of the loading volume 28 in the transverse direction. However, in other embodiments, such as the second and third embodiments illustrated respectively in Figures 4 has 8 and to the Figures 9 has 12 , the partition wall 42 comprises two panels 42a, 42b juxtaposed transversely, which are each retractable independently of one another by pivoting around the upper transverse retraction axis A46 between a vertical service position and a raised position.

[0034] An example of an anchoring mechanism 46, for a single-panel partition 42, or for a two-panel partition 42a, 42b is for example described in document EP-3.825.180 to which reference will be made for more detail. The anchoring mechanism 46 comprises for example, for each panel 42, 42a, 42b, a carriage which is arranged at the upper edge 44 of the panel and which is configured to slide and lock on a corresponding longitudinal rail 47a, 47b fixed to the ceiling 36 of the insulated bodywork. In the case illustrated in Figure 1 of a partition wall 42 with two juxtaposed panels 42a, 42b, two longitudinal rails 47a, 47b are provided fixed to the ceiling 36 of the insulated bodywork, offset from each other in the transverse direction to be arranged substantially at the middle of the corresponding panel 42a, 42b in the transverse direction. The carriage of the anchoring mechanism 46 associated with each panel preferably comprises means for anchoring the panel 42, 42a, 42b in a multitude of longitudinal positions relative to the corresponding rail 47a, 47b. The carriage may also comprise means for holding the panel in the raised position, or even in the service position.

[0035] In one aspect, the partitioning device 10 includes a lashing bar 48 that is secured to the partition 42 by a tilting mechanism 50 that allows the lashing bar to be moved between a storage position and a lashing position relative to the partition. By securing the lashing bar 48, sometimes referred to as a load stop bar, to the partitioning partition, it is ensured that it is never forgotten. It will also be seen that it participates in maintaining the partitioning partition 42 in its vertical service position, at the longitudinal position set by means of the anchoring mechanism 46.

[0036] Preferably, as shown respectively on the Figures 3 And 7, the lashing bar 48 is arranged, in the lashing position, so that its length extends in the transverse, horizontal direction, across the loading volume 28. As will be described in more detail for the second and third embodiments, the lashing bar 48 comprises two lashing ends 52a, 52b which are each provided with a lashing member 54 for lashing the lashing end 52a, 52b to the corresponding side wall 34 of the refrigerated body 11. It will be seen that this lashing of the lashing bar 48 can be done on longitudinal profiles 76 which are arranged on the side walls, and that this lashing can be done in a longitudinal position in the loading volume 28, which corresponds to the longitudinal position of the partition wall fixed by the anchoring mechanism 46.

[0037] In the stowed position, the stowage bar 48 is preferably arranged in a lower half of the partition 42, for example in an area of ​​the partition which is comprised, in height, from a lower edge of the partition 42, between 15 percent and 50 percent of the total height of the partition, more preferably between 20 and 40 percent of the total height of the partition.

[0038] In the lashing position, the lashing members 54 located at the two lashing ends 52a, 52b of the lashing bar 48 are lashed with the corresponding side wall 34 to block the lashing bar in this position and to allow the lashing bar to absorb forces in the longitudinal direction without displacement, forces which can be significant and which can be applied to the lashing bar itself or to the partition wall 42.

[0039] Preferably, the lashing bar 48 is rectilinear between its two lashing ends 52a, 52b.

[0040] In a single-panel embodiment, such as the first example illustrated in Figures 2 et 3 , the lashing bar 48 can be produced in the form of a full-width bar, the length of which is substantially equal to the width of the loading volume 28 in the transverse direction. In such an embodiment, the tilting mechanism 50 preferably determines a movement of the lashing bar 48, between its lashing and storage positions, which is parallel to a general plane of the partition 42. In the storage position, the lashing bar 48 is inclined relative to the horizontal by a storage angle which is in the range from 15 degrees to 90 degrees. In the first exemplary embodiment, a storage angle of 25 degrees relative to the horizontal transverse direction has been shown.

[0041] In the first embodiment, the movement of the lashing bar 48, between its lashing and storage positions, is a pure rotational movement around an axis of rotation A56 perpendicular to the partition 42. For this, the tilting mechanism 50 comprises an articulation 56 by which the bar 48 is articulated on the partition around the axis of rotation A56. In this first example, the articulation 56 is arranged in the middle of the length of the lashing bar 48 and the axis of rotation A56 is arranged in the center of the partition 42 in the transverse direction. Furthermore, the rotation axis A56 is preferably arranged in a lower half of the partition 42, for example in an area of ​​the partition which is comprised in height, from a lower edge of the partition 42, between 15 percent and 50 percent of the total height of the partition, more preferably between 20 and 40 percent of the total height of the partition.

[0042] In the first example and the third example embodiment, the tilting mechanism 50 comprises at least one sliding connection point 58, which is offset from the axis of rotation A56 of the bar 48, and which, without interfering with the rotation of the lashing bar 48, makes it possible to connect the lashing bar 48 to the partition 42 in the direction perpendicular to the partition 42. In the first example, the device comprises two sliding connection points 58 which are each arranged on one side of the axis of rotation A56, preferably at an equal distance from the axis of rotation A56. Each sliding connection point 58 makes it possible to take up forces which would tend to move the lashing bar 48 away from the partition 42, in particular under the effect of the application of a longitudinal force on the partition 42 when it is lashed in the service position by the lashing bar 48. Such a sliding connection point 58 will be described in more detail in relation to the third embodiment.

[0043] In an embodiment with several juxtaposed panels, it could be provided that the lashing bar is a full-width lashing bar which would be fixed, by a suitable tilting mechanism, on one of the panels. In such a case, it will advantageously be provided that the axis of rotation A56 of the bar 48, determined by the articulation 56, is offset along the bar, relative to the center of the latter in the direction of its length so as to be closer to one of its lateral ends 52a, 52b than to the other.

[0044] However, in embodiments with several juxtaposed panels, such as the second example and the third example, the lashing bar 48 is preferably made in the form of a lashing bar 48 in several parts, preferably in as many parts as there are panels 42a, 42b. Thus, the lashing bar 48 comprises, in the second and third examples, a first half-bar 48a which is fixed on a first 42a of the two panels, by a first tilting mechanism 50a which allows the movement of the first half-bar 48a between a storage position and a lashing position relative to the first panel 42a, and a second half-bar 48b which is fixed on the second panel 42b by a second tilting mechanism 50b which allows the movement of the second half-bar 48b between a storage position and a lashing position relative to the second panel 42b.In the examples, the two half-bars 48a, 48b and their respective tilting mechanism 50a, 50b are identical and symmetrical to each other with respect to a median vertical and longitudinal plane of the loading volume, because in the examples the two panels 42a, 42b of the partition wall are of identical width in the transverse direction. For the case where the two panels do not have the same width in the transverse direction, it would be possible to have half-bars of different lengths, or, alternatively, half-bars of identical lengths.

[0045] Each half-bar 48a, 48b has a medial end 60a, 60b, transversely towards the center of the loading volume in the stowed position, and a lateral end 52a, 52b, transversely towards the corresponding side wall of the refrigerated body 11. The lateral end 52a, 52b of each half-bar 48a, 48b is provided with a stowage member 54 on the corresponding side wall 34 of the refrigerated body. Thus, the lateral end 52a, 52b of each half-bar forms a stowage end of the stowage bar 48 taken as a whole. Each half-bar 48a, 48b is preferably rectilinear between its medial end 60a, 60b and its lateral end 52a, 52b. Preferably, when each of the half-bars 48a, 48b forming the lashing bar 48 is in the lashing position, they are aligned in a rectilinear manner, so as to form a rectilinear lashing bar 48.

[0046] In an embodiment with several juxtaposed panels, the tilting mechanism 50a, 50b determines a movement of each half-bar 48a, 48b, between its stowed and storage positions, which is preferably parallel to a general plane of the corresponding panel 42a, 42b on which it is fixed by the tilting mechanism 50a, 50b.

[0047] In the examples, the tilting mechanism 50a, 50b of a half bar 48a, 48b comprises an articulation 56a, 56b by which the half-bar 48a, 48b is articulated on the corresponding panel 42a, 42b around an axis of rotation A56a, A56b perpendicular to the corresponding panel.

[0048] In the stowed position, each half-bar is preferably horizontal. In the storage position, each half-bar 48a, 48b is preferably inclined relative to the horizontal by a storage angle which is in the range from 15 degrees to 90 degrees. In the second example, it can be seen at figures 4 And 5 that the storage angle of each half-bar is 90 degrees. In the third example, the storage angle of each half-bar is expected to be 25 degrees.

[0049] In the stowed position, the stowage members 54 located at the stowage ends 52a, 52b of each of the two half-bars 48a, 48b are stowed with the corresponding side wall 34 to lock the bar in this position. An embodiment of a sliding connection point 58 is illustrated in more detail in Figures 10 and 11, more particularly in the case of a half-bar 48a, 48b for a partition 42 with two juxtaposed panels. However, the same design can be used in the case of a single-part stowage bar 48, for a single-panel partition, as illustrated in Figures 2 et 3 .

[0050] In the illustrated embodiments, each lashing member 54 comprises a sliding finger 64 which is illustrated more particularly in the Figures 10 et 11 . As seen in these figures, the sliding finger 64 is mounted at the lateral end 52a, 52b of the half-bar 48a, 48b and it extends and slides relative to the half-bar 48a, 48b in the direction of elongation of the half-bar 48a, 48b in question, being urged transversely outwards, in the direction of the lateral wall 34 corresponding to the lateral end 52a, 52b in question, towards a projecting lashing position. The sliding finger 64 can thus slide between an unlocked retracted position and its projecting lashing position in which it projects transversely outwards in the direction of elongation of the half-bar 48a, 48b, to cooperate with lashing means 74, 76 of the corresponding lateral wall 34.

[0051] In the example, the lashing member 54 comprises a cartridge forming the housing 66, which is mounted at the lateral end 52a, 52b considered of the half-bar 48a, 48b. The sliding finger 64 has a base 68 which slides in a housing delimited by the cartridge 66, while the sliding finger 64 projects transversely towards the outside of the cartridge 66 through an orifice 72 facing towards the lateral wall 34 corresponding to this lateral end 52a, 52b. A compression spring 70 may be provided, housed in the housing delimited by the cartridge 66, and bearing on the base 68 of the sliding finger 64 to urge it outwards towards its projecting lashing position.

[0052] In the exemplary embodiments, the side walls 34 of the refrigerated body 11 comprise, as lashing means, a series of indentations 74 in which the sliding finger 64 can be received when the lashing bar 48, or the half-bar 48a, 48b is in the lashing position. Each indentation 74 is positioned longitudinally in the loading volume 28 so as to correspond, at least approximately, to a longitudinal position of the partition wall 42 determined by the anchoring mechanism 46.

[0053] In a manner known in the field of lashing bars, these impressions 74 can be formed on a longitudinal profile 76 fixed on an internal surface of each of the side walls 34 of the body 11. The longitudinal profile 76 is for example made of metal, for example folded and cut sheet metal. Two longitudinal profiles 76 are therefore arranged transversely facing each other on either side of the loading volume, each on an internal surface of one of the side walls 34 of the refrigerated body 11, at the same height as the lashing bar 48 in the lashing position. The indentations 74 of the two longitudinal profiles 76 are arranged in correspondence along the longitudinal direction, in the sense that an indentation 74 of one of the longitudinal profiles 76 is arranged at the same longitudinal position, in the loading volume 28, as a corresponding indentation of the other of the longitudinal profiles 76.

[0054] Generally, the securing members of the securing bar 48 are configured, with the corresponding securing means of the bodywork, to at least ensure blocking of the securing bar in the longitudinal direction capable of retaining loads during movement of the vehicle, and capable of absorbing forces applied to the partitioning device during loading and unloading.

[0055] As can be seen more particularly on the Figure 9 and on the Figure 11 , an example of longitudinal profile 76 has, in a vertical transverse plane, a gendarme hat profile, the lower and upper edges of which form lower and upper longitudinal portions 78, 80 for fixing on the side wall 34, and a central portion of which, between the lower and upper longitudinal portions 78, 80, is in relief transversely towards the center of the loading volume relative to the internal surface of the side wall 34 on which the longitudinal profile 76 is fixed. In this central portion, which extends over the length of the longitudinal profile 76, the indentations 74 intended to accommodate the sliding finger 64 are arranged at regular intervals. The indentations 74 are for example formed by cutouts and flaps of the sheet metal forming the longitudinal profile 76.

[0056] The sliding finger 64 is received in a recess 74 to form a bolt received in a striker, and to block the lashing bar 48 or the half-bar 48a, 48b in the lashing position, at least in the longitudinal direction.

[0057] In the example of the Figures 10 et 11 , the sliding finger 64 has an upper inclined face 82, which, when the half-bar 48a, 48b arrives from its storage position towards its lashing position, comes to bear on the lower edge of the central portion of the longitudinal rail 76 to cause, by cam effect, the automatic retraction of the sliding finger 64 towards the inside of the cartridge 66, allowing the half-bar 48a, 48b to reach its lashing position. When the half-bar 48a, 48b has reached its lashing position, the sliding finger 64 is located opposite an imprint 74 in which it engages, under the effect of the spring 70, to lash the half-bar 48a, 48b in the lashing position. Thus, automatic lashing of the lashing bar or the half-bar in the lashing position is obtained.

[0058] In the example of the Figures 10 et 11 , the sliding finger 64 has a lower inclined face 84, which, when the bar leaves its securing position, by manipulation by the user, causes automatic unsecuring of the securing member 54, allowing, beyond a certain force applied to the securing bar 48 rotating around the axis of rotation A56a, A56b, to automatically retract the locking finger 64 against the spring 70, and therefore to pivot the half-bar 48a, 48b towards its storage position.

[0059] It is noted that such automatic unfastening occurs only when a rotational force is applied to the half-bar 48a, 48b around the rotation axis A56a. This automatic unfastening does not occur when a force perpendicular to the partition 42 in the service position is applied to the bar 48 or to the partition 42. In this way, the automatic unfastening of the lashing member 54 in no way reduces the capacity of the lashing bar 48 to absorb forces in the longitudinal direction without displacement, forces which may be significant and which may be applied to the lashing bar 48 itself or to the partitioning partition 42.

[0060] However, such automatic lashing or unlashing is not mandatory. In the second embodiment illustrated more particularly in figures 4 And 8, the lashing member 54 can be manually unlashed by the user by a pull tab 85 which is provided to allow the sliding finger 64 to be retracted against the compression spring 70. This second embodiment, by the presence of the compression spring 70, however allows automatic lashing. However, it could also be provided that the lashing of the lashing member 54 is also manual, for example with a lashing member with a sliding finger 64, without a spring, but allowing, thanks to the pull tab 85, the sliding finger 64 to be moved towards its projecting lashing position.

[0061] Preferably, the partitioning device 10 comprises means for locking the medial ends 60a, 60b of the half-bars 48a, 48b in the stowed position, in order to lock the rotation of the half-bars in the stowed position. These locking means could comprise means for locking, on the partition 42, the medial end 60a, 60b of a half-bar 48a, 48b in question, for example by locking the medial end 60a, 60b on the panel 42a, 42b corresponding to this half-bar 48a, 48b in question.

[0062] However, in the second and third examples, the device comprises, as means for locking the medial ends 60a, 60b, means for mutually embedding the medial ends 60a, 60b of the half-bars 48a, 48b in the lashing position. Indeed, in these embodiments, the half-bars 48a, 48b in the lashing position are aligned and their medial ends 60a, 60b face each other.

[0063] In these two examples, the mutual embedding means comprise an embedding sleeve 62 which is slidably mounted on one of the two half-bars, between an unlocked position, illustrated for example in the figures 5, 6 And 9 , and a locking position shown on the Figures 4 And 7 .

[0064] In the examples, each half-bar 48a, 48b is made in the form of a square-section profile, and the embedding sleeve 62 has an internal profile of complementary square section, so as to be able to slide along the half-bar. Of course, each half-bar 48a, 48b could have a section of a shape other than square. The sleeve does not necessarily have a section of the same shape, but preferably a section which slides with reduced play on the half-bars. In the examples, the embedding sleeve 62 is mounted on a first half-bar 48a, and, in the unlocked position, it is received between the lateral end 52a and the medial end 60a, leaving the latter visible. When the two half-bars 48a, 48b are brought into their stowed position, as illustrated in figure 6 for example, a user can then cause the embedding sleeve 62 to slide towards its locking position illustrated for example in Figure 7 . In the locking position, the embedding sleeve 62 is received astride the two medial ends 60a, 60b opposite the two half-bars, being embedded with minimal play on these two ends. Once the two half-bars are joined by the embedding sleeve 62, neither of them can pivot around its axis of rotation A56a, A56b.

[0065] In some embodiments, it could be provided for example that the axis of rotation A56a, A56b of the half-bar 48a, 48b, determined by the articulation 56a, 56b, is located at the center of the half-bar in the direction of its length, so as to have each half-bar balanced with respect to its axis of rotation A56a, A56b. However, in other embodiments, as illustrated in the figures, the axis of rotation A56a, A56b of the half-bar 48a, 48b, determined by the articulation 56a, 56b, is offset along the half-bar, with respect to the center thereof, in the direction of its length, so as to be closer to the lateral end 52a, 52b of the half-bar than to its medial end 60a, 60b.For example, the rotation axis A56a, A56b is offset along the half-bar so as to be arranged at a distance from the lateral end 52a, 52b of the half-bar which is for example in the range from 10 percent to 40 percent of the length of the half-bar 48a, 48b.

[0066] Such an arrangement has two advantages. A first advantage results from the fact that this provides, when handling the half-bar 48a, 48b between its stowed and stored positions, a leverage effect, when handling the half-bar 48a, 48b by its medial end 60a, 60b, to engage or disengage the stowage member 54 located at the lateral end 52a, 52b.

[0067] A second advantage of this offset of the rotation axis A56a, A56b is obtained by providing that, as in the embodiment examples, in the storage position, the medial end 60a, 60b of the half-bar considered is located vertically above the level of the articulation axis A56a, A56b, while the lateral end 52a, 52b of said half-bar considered is located vertically below the level of the disarticulation A56a, A56b. Indeed, starting from the assumption that the center of gravity of the half-bar 48a, 48b is arranged close to the middle of the latter in the direction of its length, it is therefore understood that the offset of the axis of rotation A56a, A56b towards the lateral end 52a, 52b means that the half-bar has a center of gravity which is closer to the upper transverse retraction axis A46 when the half-bar lashing bar 48a, 48b is in the storage position than when it is in the lashing position.Indeed, the section of the half-bar 48a, 48b between the axis of rotation A56a, A56b and the medial end 60a, 60b is longer, and therefore heavier, than the section of the half-bar 48a, 48b between the axis of rotation A56a, A56b and the lateral end 52a, 52b. The longer section is therefore, in the storage position, above the level of the articulation 56a, 56b. Now, an advantage of having the center of gravity of the half-bar closer to the upper transverse retraction axis A46 is that it is easier to raise the panel 42a, 42b to the raised position.

[0068] In certain embodiments, in particular in the first embodiment and the third embodiment, the partitioning device comprises a member for returning the half-bar 48a, 48b to its storage position. The return member may be an elastic return member, or the like. This proves particularly useful for the third embodiment, when the axis of rotation A56a, A56b is offset as described above, and the center of gravity, in the storage position, is located above the articulation 56a, 56b as described above. Indeed, in such a case, in the absence of an elastic return member, the half-bar 48a, 48b would tend to return to its stowed position under the effect of gravity. On the Figure 10 , an exemplary embodiment of an elastic return member has been illustrated, which in this case is integrated into the articulation 56a, 56b, which forms an articulation with an integrated elastic return towards the storage position. The articulation 56a, 56b comprises a cylinder of square section of small section 86, the central axis of which forms the axis of rotation A56a, A56b, secured to a base 88 allowing the fixing of the articulation 56a, 56b on the partition 42. The articulation 56a, 56b also comprises a cylindrical tubular profile 90 of square section, hollow and of large section. The cylinder of square section of small section 86 is received inside the cylindrical tubular profile 90, the two square sections being offset in rotation by 45 degrees around the axis of rotation A56a. Four elastomer pads 92 are interposed between the two to bring them back into this 45-degree offset position, which corresponds substantially to the storage position.When the half-bar 48a, 48b is brought to its stowed position, the cylindrical tubular profile 90 pivots around the axis of rotation A56a relative to the square-section cylinder 86, crushing the elastomer pads 92, thus generating a return force. Of course, other return members can be provided, for example in the form of an angular spring around the articulation 56a, 56b, or in the form of a gas cylinder or a helical traction or compression spring interposed between the half-bar 48a, 48b and the partition 42.

[0069] In the second embodiment, it is provided, as illustrated more particularly in the figure 8 , that the articulation has a laxity along the axis of rotation A56a, A56b. For example, the articulation 56a, 56b has, between the half-bar 48a, 48b and the partition 42, a set of springs allowing a laxity along the axis of rotation. This laxity is particularly useful when the lashing bar 48 is lashed in the lashing position between the two side walls 34 of the bodywork 11, in the event that a force is applied to the partition 42. This can happen for example during loading or unloading operations. In this case, the laxity at the articulation 56a, 56b makes it possible to limit the risks of tearing of the articulation 56a, 56b relative to the partition 42, by allowing a slight displacement of the partition 42 relative to the lashing bar 48. Such laxity in a direction perpendicular to the partition can also be provided within the framework of the first embodiment comprising a single panel 42 and a lashing bar 48 in a single part.

[0070] In the third exemplary embodiment, similarly to the first exemplary embodiment, the tilting mechanism 50a, 50b of a half-lashing bar 48a, 48b comprises at least one sliding connection point 58, offset from the axis of rotation A56a, A56b of the half-bar 48a, 48b and which, without interfering with the rotation of the half-lashing bar 48a, 48b around the axis of rotation A56a, A56b, makes it possible to connect the half-lashing bar 48a, 48b to the partition 42 in the direction perpendicular to the partition 42. An embodiment of a sliding connection point 58 is illustrated, more particularly in the case of a half-bar for a partition 42 with two juxtaposed panels, on the Figure 12 . However, the same design can be used in the case of a single-piece tie-down bar 48, for a single-panel bulkhead, as shown in Figures 2 and 3.

[0071] On the Figure 12 , we see that the tilting mechanism 50a comprises a slide 94 in an arc of a circle around the axis of rotation A56a. The figure 12 represents only a half-bar 48a and its tilting mechanism 50a, with an angle of view opposite to that of Figure 9 , as seen by transparency through the partition 42, the latter not being illustrated in this figure. The slide 94 extends over an arc of a circle which is preferably at least equal to the angle between the storage and stowage positions of the stowage bar 48a, 48b. In the example of the Figure 12 , the slide 94 is integral with the partition 42. It is for example fixed on a base 96 of the tilting mechanism 50a, of which one can see here a fixing face on the panel 42a of the partition 42. The tilting mechanism 50a also comprises a claw 98 which is retained by the slide 94 in at least one direction in the direction perpendicular to the panel, therefore the direction of the axis of rotation A56a, A56b, but which can slide in the slide 94 according to the arc of a circle around the axis of rotation A56a, A56b. In the example, the claw 98 is integral and fixed relative to the half-bar. It could be provided that the slide is integral with the half-bar 48a, 48b, while the claw would be integral with the panel 42a, 42b. The claw 98 prevents the lashing bar 48a, 48b from moving away from the slide 94 in the direction perpendicular to the partition 42.It thus prevents a torque being applied to the joint 56a, 56b around an axis perpendicular to the axis of rotation A56a, A56b which would cause a tendency for the joint 56a, 56b to tear off.

[0072] In the example, the slide comprises two parallel rails 100 in an arc around the axis of rotation A56a, separated by a slot 102. The claw 98 is in the form of a cylindrical pin which extends perpendicular to the partition from the half-bar 48a, 48b, in the direction of the partition 42, and which extends through the slot between the two rails. The claw 98 comprises an enlarged head which bears on a face of the rails facing away from the half-bar 48a, 48b. The enlarged head, visible on the Figure 12 , prevents the claw 98 from being removed from between the two rails 100 in the direction perpendicular to the partition, in the direction of the spacing of the half-bar 48a, 48b relative to the partition 42.

[0073] It is noted that the sliding connection point 58 prevents the lashing bar 48a, 48b from moving away from the slide 94 in the direction perpendicular to the partition 42 regardless of the position of the lashing bar 48a, 48b between its storage and lashing positions. Alternatively, it could be provided that the device comprises, on at least one panel, a hooking member offset from the axis of rotation of the corresponding half-bar, and on which the half-bar 48a, 48b would hook in the lashing position to secure the half-bar with the hooking member in the direction perpendicular to the panel. Such a hooking member may, for example, be in the form of a hook or a bracket, a distal arm of which extends parallel to the partition so that the half-bar 48a, 48b, in the lashing position, finds itself wedged, in the direction perpendicular to the panel, between the partition 42 and the distal arm of the hooking member.Such a latching member performs the same function as the sliding connection point 58 described above, but only in the lashing position, in which the anti-tearing function is most useful.

[0074] In the second example of realization, we can see in particular at the figure 8that the device comprises, on at least one panel, a stop 104 which is offset from the axis of rotation of the corresponding half-bar, and on which the half-bar 48a, 48b comes to bear in the lashing position to block the rotation of the half-bar in rotation around the axis of rotation A56a, A56b, thus forming an angular stop for the half-bar 48a, 48b. In the example illustrated, the stop 104 also forms a spacer wedge which guarantees, in the lashing position, a predefined spacing between the partition 42 and the half-bar 48a, 48b, in the direction perpendicular to the panel 42a, 42b. Such a stop 104 can easily be transformed into a hooking member as described above, by producing it in the form of a hook or a bracket having a distal arm parallel to the partition.
