Description

TECHNICAL AREA

The present invention relates to the field of pallet boxes, and more particularly to pallet boxes intended for the transport of bulky products, such as motor vehicle seats and / or benches.

STATE OF THE ART

A pallet box generally comprises a base forming a pallet to allow its handling, a belt and a cover. A pallet box is convertible between a loading configuration in which the belt is unfolded and erected on the base so as to form a storage volume and an empty transport configuration in which the belt is folded up and laid flat on the base. Such a pallet box is for example presented in the documents EP-A1-2 193 998 and EP-A1-2 690 027 on behalf of the plaintiff.

In order to optimize in particular the storage and transport of pallet boxes, the latter can be stacked and in other words stacked vertically one on top of the other. Thus, the cover comprises for example several studs able to engage in cavities of complementary shape and formed in the base.

The dimensions of the pallet boxes are generally chosen according to the means of transport used and the goods to be transported in order to maximize the loading and thus reduce the cost of transport. Thus, for example for transport by truck, depending on the goods to be transported, the user has various models of pallet boxes each having dimensional characteristics adapted to the storage space defined by the trailer of the truck, and namely for example an optimized stack of two or three pallet boxes depending on the model.

This standardization nevertheless requires the user, for certain bulky objects to be transported such as motor vehicle seats and / or benches, to tilt these objects in order to adapt to the models of pallet boxes offered.

At present, the user uses for example one or more wedges provided with inclined planes in order to position and orient the object to be transported in the storage volume of the pallet box.

Such loading is however not optimized.

First, these wedges are positioned manually and without visual cues on the base, upstream of the introduction of the object to be transported into the storage volume. Thus, the user must regularly repeat it several times in order to position and correctly orient the object in the storage volume, to the detriment of productivity.

Second, these bulky holds are stored separately when the pallet boxes are converted from the loading configuration to the empty return configuration. Thus, it is essential that they are repatriated simultaneously to the pallet boxes on the loading stations so that the loading chain is not immobilized.

Third, the wedges are simply attached to the base of the pallet box. Thus, during transport, under the jolts caused by the irregularities of the roadway, the objects can move, and in particular damage the means for locking the cover on the belt and / or the structure of the belt.

The prior art also includes documents JP-A-2015016872 , WO-A1-03 / 068616 , US-A-3472363 , EP-A2-1947019 , WO-A1-2012 / 136706 , WO-A1-2015 / 023519 .

The objective of the present invention is therefore to provide a pallet box allowing easy loading of the object to be transported, this pallet box also being quickly convertible and compact.

DISCLOSURE OF THE INVENTION

The invention provides for this purpose a pallet box comprising at least one base and an articulated belt, the pallet box being convertible between a loading configuration in which the belt is unfolded and erected on the base so as to form a storage volume and an empty transport configuration in which the belt is folded up and laid flat on the base;
characterized in that it comprises at least one hinged bottom panel resting on the base and capable of forming a wedge for a bulky object, such as a motor vehicle seat, to be loaded into the storage volume, and in that the panel comprises a tray and a flap articulated with the tray around a first fold line substantially parallel to the base, this flap being movable between a deployed position in which the flap is angularly spaced apart by a predetermined angle of the panel so as to form the wedge for the object and a retracted position in which the flap is parallel to the tray, and this flap being housed in a recess of the tray when it is in its retracted position.

In the present application, the term “erected belt” is understood to mean a belt which extends substantially perpendicularly to the base, for example vertically, and by “belt laid flat” a belt which extends substantially parallel to the base (this is i.e. at the base plane) for example horizontally.

First, during loading, the operator simply has to deploy the panel upstream of the introduction of the bulky object to be transported into the storage volume, for the benefit of productivity and ease of loading.

Second, a hinged panel can easily be folded up and laid flat with the belt between the base and the cover, when the pallet box is converted from a loading configuration to an empty transport configuration, for the benefit of compactness.

Thirdly, during transport, a panel helps to ensure the stability of the bulky object loaded in the storage volume.

DETAILED DESCRIPTION

On the figure 1 is shown a pallet box 1 capable of storing at least one bulky object, and according to the example illustrated two front seats 2 ( figure 5 ) contiguous and a rear seat 3 ( figure 6 ) of a motor vehicle.

The pallet box 1 comprises at least one base 4 forming a pallet and an articulated belt 5, the pallet box 1 being convertible between a loading configuration (illustrated on figures 1 and 2 ) in which the belt 5 is unfolded and erected on the base 4 so as to form a storage volume and an empty transport configuration (shown in the figure figure 3 ) in which the belt 5 is folded and laid flat on the base 4.

• une direction longitudinale, horizontale, confondue avec la longueur de la base 4,
• une direction transversale, horizontale, confondue avec la largeur de la base 4,
• une direction verticale, confondue avec la hauteur de la base 4.

By convention in the present application, the following directions are defined with respect to the pallet box 1:

• a longitudinal, horizontal direction, coincident with the length of the base 4,
• a transverse, horizontal direction, coincident with the width of the base 4,
• a vertical direction, coincident with the height of the base 4.

According to the embodiment illustrated in the figures, the pallet box 1 further comprises a cover 6 covering in particular the storage volume in the loading configuration and a collar 7 surrounding the belt 5 when the pallet box 1 is in the loading configuration, this collar 7 being fixed to the base 4. The collar 7 is obtained for example by folding a polypropylene plate with a bubble structure marketed under the brand Akyboard ® or a cellular polypropylene plate marketed under the Akylux ® brand or by double skin thermoforming.

In the loading configuration illustrated in particular on the figure 1 , the belt 5 is fixed to the base 4 and to the cover 6 by means of locking means housed respectively in the base 4 and the cover 6. In the vacuum return configuration illustrated in particular on the figure. figure 3 , the cover 6 is fixed to the collar 7 by means of the locking means of the cover 6. Such locking means are in particular presented in more detail in the document EP-A1-2 193 998 on behalf of the plaintiff.

According to the embodiment illustrated in the figures, the belt 5 is formed of plates 8 articulated around vertical folding axes, and in other words perpendicular to the base 4 when the pallet box 1 is in the loading configuration. The belt 5 corresponds to a foldable belt 5 in M by analogy to the shape of the belt 5 during the folding (respectively deployment) of the latter. The belt 5 is obtained for example by folding a polypropylene plate with a bubble structure marketed under the trademark Akyboard® or a cellular polypropylene plate marketed under the trademark Akylux®. The belt 5 is only partially shown on the figure 2 .

According to the embodiment illustrated in the figures, to make it possible to stack the pallet boxes ( figure 4 ), and in other words to stack them vertically on top of each other, the cover 6 comprises six studs 9 able to engage in cavities of complementary shape and formed in the base 4. The cover 6 and the base 4 are for example obtained by double skin thermoforming.

Such a pallet box 1 is for example marketed under the brand Uni-Pak®.

Advantageously, to minimize its mass, the various components of the pallet box 1 are made of plastic, for example polypropylene or polyethylene.

The pallet box 1 also comprises a hinged bottom panel 10 resting on the base 4 and capable of forming a wedge for two seats 2 contiguous longitudinally of a motor vehicle to be loaded into the storage volume.

More precisely, the panel 10 comprises a plate 11 and a flap 12 articulated with the plate 11 around a first (longitudinal) folding line 13 substantially parallel to the base 4, this flap 12 being movable between an extended position ( figures 1, 2 , 7 , 8 , 10 to 14 , 17 , 21 and 22 ) in which the flap 12 is angularly spaced apart by a predetermined angle A of the panel 10 so as to form the wedge for the two seats 2 and a retracted position ( figures 3 , 9 , 15 and 16 ) in which the flap 12 is parallel to the plate 11. A fold line thus forms a hinge or an articulation.

In other words, in the deployed position, the panel 10 makes it possible to wedge the two seats 2 in an inclined manner so that the latter are included in the storage volume.

Thus, when the pallet box 1 is in the loading configuration ( figures 1 and 2 ), the panel 10 rests on the base 4 in the deployed position in the storage volume. Conversely, when the pallet box 1 is in the empty return configuration ( figure 3 ), the panel 10 rests on the base 4 in the retracted position below the folded belt 5, and more generally within the volume defined by the collar 7 between the base 4 and the cover 6.

Advantageously, to minimize its mass, the panel 10 is made of plastic, and for example of polypropylene or polyethylene.

According to the embodiments illustrated in the figures, in the deployed position, the flap 12 is angularly separated from the plate 11 by a predetermined angle A so that the angle B between the plate 11 and the base 4 is between 15 ° and 25 °.

According to the embodiments illustrated in the figures, the panel 10 further comprises a sole 14 articulated with the plate 11 around a second (longitudinal) fold line 15 parallel to the first fold line 13 and opposite to the flap 12, the sole 14 forming a support for the rear seat 3.

The first and second fold lines 13, 15 are formed by local compression of the material and / or thinning of the thickness of the panel 10.

Alternatively, not shown, the first and second fold lines 13, 15 are formed by one or more hinges.

In the remainder of the description, different embodiments of the panel 10 are presented, the elements common between these embodiments keep the same numbering.

According to the first embodiment of the panel 10 illustrated in the figures 7 to 10 , when the flap 12 is in the deployed position ( figures 7, 8 and 10 ), the flap 12 is substantially perpendicular to the base 4 and forms a support for the plate 11. According to the present invention, when the flap 12 is in the retracted position ( figure 9 ), the flap 12 is housed in a recess 16 of the plate 11 of complementary shape, this architecture makes it possible in particular to minimize the height of the pallet box 1 when the latter is in the empty return configuration.

In order to facilitate the positioning of the panel 10 on the base 4 and to avoid any transverse movement of the panel 10 during transport, the sole 14 can be in abutment against a first plate 8a (longitudinal) of the belt 5 and the flap 12 can be in abutment against a second plate 8b (longitudinal) of the belt 5 when the flap 12 is in the deployed position ( figures 7, 8 and 10 ), the first plate 8a being opposite the second plate 8b.

The plate 11 further comprises four transverse grooves 17, joined together in pairs, each of these grooves 17 opening into the recess 16 near the first folding line 13 and being delimited by a bearing face 18 near the second folding line 15. The grooves 17 are each suitable for receiving a slide 19 of a device 20 for adjusting a front seat 2, these slides 19 being suitable for being fixed to a floor of a motor vehicle body. When the seat 2 is positioned on the plate 11, the slides 19 are in abutment against the bearing faces 18 of the grooves 17.

The panel 10 further comprises a wall 21 for wedging a backrest 22 of the rear seat 3, this wall 21 being articulated with the sole 14 around a third (longitudinal) fold line 23 substantially parallel to the first and second lines. 13, 15 folding.
