Description

CORNER FOR RECEIVING WALLS OF A FUND AND

FOLDABLE BOX ASSEMBLY AND REMOVABLE

The present invention relates to an angle element, commonly called "pad" or "angle" to assemble side walls of a box, and more particularly of a crate, ie whose walls are consisting of slats spaced apart from each other.

The invention also relates to a device and a method of assembling such a box comprising brackets.

Finally, the present invention also relates to a collapsible box and removable thanks to such an assembly device.

[0004] "body" means any container or receptacle having at least two adjacent walls, and intended to contain an object.

Traditionally, the assembly of the different walls of a body requires the use of fixing means such as nail, glue, or screw.

This type of assembly method, however, has various disadvantages. For example, if walls are poorly assembled, it is very difficult or impossible to separate them without damaging part of the walls to reassemble them properly.

For example, patent FR2805521 discloses a box comprising a pair of angles (an upper angle and a lower angle) to dismountably assemble two adjacent walls of the body. However, this type of assembly device generally requires the use of fastening means to maintain the angles in position once the body mounted.

An object of the invention is to provide an assembly system that facilitates the assembly, i.e. assembly and disassembly of a box, and gives stability and rigidity to the body. In addition, the angles must be maintained without the use of additional fasteners. It is thus possible to quickly assemble and dismount a box in minutes.

Another object of the present invention is to ensure the integrity of the device, i.e. the box once mounted, or even the security of the box (no access to the content).

Another problem raised here relates to the strength of the device, or even the mounted box. And another, the maintenance of angles, crate mounted.

A corollary problem relates to the speed of implementation and / or removal of angles, crate mounted. Another, the catch-up of game possibly necessary on the box, in particular in height.

For this purpose is proposed, an angle to assemble a box, without necessarily using tools. Each angle has spaces oriented in two transverse directions and adapted to receive walls of the box with which the angle is adapted to be assembled, each space being delimited by an outer side wall (an edge wall) and an inner side wall of said angle iron. For clarity later, the different walls of an angle will be called "Partitions" so as not to be confused with the walls of the box. Said bracket also has at least one tab provided with a transverse retaining zone, said tab being adapted to engage in a slot in a wall of the box, preferably parallel to an edge of the wall, and to be there held by stop of its transverse zone.

Such tab form, provided with a transverse retaining area, preferably flat and thin, extending parallel to the edges (lower or upper) of a wall of a box, facilitates the handling of the angles.

A slot as considered may have an open or closed contour.

For example, a body wall is generally formed from slats, for example, a lower slat, an upper slat and two side slats (a right and a left) called "amounts".

By higher, lower, right and left is meant the positioning of the considered objects when a box according to the invention is assembled.

Thus, according to a first example, the slot can be formed only by the lower edge of the upper lath of the wall, such a slot then has an open contour. In this case, the transverse retaining zone of the tab is engaged under the upper lath.

Thus, it is not necessary to make slots, nor horizontal nor vertical, in the walls of the box to be able to fix an angle. According to a second example, a slot as considered may be a housing of determined dimensions formed in the upper lath of the wall, such a slot then has a closed contour.

It can be the same with a lower batten.

Thus, no nail or tool is needed to assemble the box.

Preferably, each slot of the walls of the box must be arranged in accordance with the shape and position of the tab of the angle that it must receive.

Typically, two external walls juxtaposed with an angle define an angle of 90 ° between them. However, this angle can vary to suit the type of body that you want to assemble.

Preferably, the lug provided with its transverse retaining zone defines an elastically deformable clip. The elastic structure of the tab then facilitates its insertion and withdrawal from the slot without damaging the angle or the box.

Preferably, the transversal retaining zone of a tab has an asymmetrical shape, for example in the form of a knife blade to facilitate insertion and / or extraction of the tab in the slot.

Preferably, the tab also has a hooked area, for example a hole, which can be used to insert a tool to facilitate the disengagement of the tab of the corresponding slot. According to an advantageous embodiment, each outer side wall has at least one leg, each leg being adapted to cooperate with a corresponding slot in a wall to form the body. The presence of tabs only on the outer side walls of the angles thus makes it easier to dismantle the box.

According to another advantageous embodiment, each inner partition has at least one lug, each lug being adapted to cooperate with another corresponding slot, preferably arranged on the inner face of the walls intended to form the body. Advantageously, the slots of the walls of the box intended to receive the legs of the inner side walls are through. Thus, when dismounting the box, it is possible to insert a tool into the slot to push the tab to the inside of the box to dislodge and remove the angle.

Therefore, in the case where an angle bracket has both tabs on the inner side walls and on the outer side walls, it is preferable that the tabs of the inner side walls are longer than the tabs of the outer side partitions. , so that the latter do not obstruct the slots of the legs of the inner side walls.

Advantageously, the bracket comprises a transverse partition, and preferably orthogonal to the inner and outer side walls, forming a bottom stop. Thus, when the transverse wall is an upper wall, the angle forms an upper angle, and the tabs are then located at the lower ends of the corresponding side walls. When the transverse partition is a lower partition, the angle forms a lower angle, and the legs are then located at the upper ends of the corresponding side walls.

Advantageously, the transverse partition has a guide wall, serving as a lateral stop for an element (for example another body) which would be placed on the body, to wedge its position. Preferably, the guide wall is located in the extension of the outer side walls of said bracket.

These guide walls are advantageously located on an upper angle and may have a flared shape to facilitate the superposition of another element on the body. They serve in particular to strengthen the holding position of this other superimposed element.

The angle may further have various other features. For example :

^■ The transverse partition may have a perforated area, for example a hole, which may allow to introduce a tool adapted to catch a hooked area of an inner lug to facilitate its extraction of the slot.

^■ An upper angle can have, on the upper face of its transverse partition, anti-slip pins to reinforce also the maintenance in position of another superimposed element, for example another box. These spikes preferably have a sharp, tapered shape, so that a superimposed element can be fixed on it. ^■ A lower angle may have, on the underside of its transverse wall, fastening means for securing the box to a support member, such as a pallet. These attachment means can also be pins, or staples, or any other mechanical hooking system, or even a chemical means such as glue.

According to another aspect of the invention, there is shown a polygonal box comprising:

walls, each wall having at least one slot,

- and several angles,

at least one bracket being of the type of those defined above.

Preferably, all the upper angles used are identical and all the lower angles used are identical. Moreover, there are as many upper angles than lower angles. In addition, it is also possible to have upper angles identical to the lower angles.

According to a preferred embodiment, the body comprises a cover arranged to cover an upper opening that the walls of the body define between them, towards the top of the body. Advantageously, the upper angles cover said lid at an angle of the box. This type of configuration allows a seal of the body that can not then open accidentally. The lid can be removed when dismounting the box.

According to another preferred embodiment, the body comprises a pallet on which stand its walls.

Advantageously, the lower angles are fixed to the pallet, above it.

For mounting, the walls of the box slide in lower angles provided with tabs which, by elastic deformation, slip into the corresponding slots of the walls.

The upper angles are inserted by sliding down on the upper ends of the walls of the box and pressing on each angle until the tabs engage in the corresponding slots.

Then it is possible to fix a lid.

The disassembly is done by two movements:

Preferably, the inner lugs of the upper angles of their respective slot are first removed, if these inner lugs exist:

^■ If the box is closed by a cover that it is not possible to remove independently of the upper angles, it is necessary to dislodge the inner legs of the upper angles by inserting an object, for example about 7 cm long and 7 mm maximum diameter such as a screwdriver, in each slot (which must then be through), the legs will come out of their housing with a movement towards the interior of the box.

^■ If the crate is not closed by a cover or the cover has been removed, the inner tabs of the upper brackets must be pushed out slightly to remove them from their seats and pull the bracket upwards.

Advantageously, the tabs have a notch serving as a hooked area, for example a hole, in which it is possible to insert a tool to facilitate the disengagement of the tab.

It is then possible to introduce a tool through perforated zones of the transverse partition of the upper angles to grip these hooked zones of the inner legs.

Both methods can also be performed simultaneously if necessary, namely inserting a tool into the slots to push the tabs inward while inserting another tool in the hooked areas.

Then, remove the ends of the legs of the outer side walls to remove them from their housing, and pull the angle iron towards In the case where the angles have only outer legs, only this second step is then necessary.

Thus, the inner legs may have a geometry that provides them with greater elasticity to facilitate disassembly.

A similar approach is to remove the lower angles.

Another solution to at least part of the problems raised consists of an assembly device comprising a pair of angle and a traction element interconnecting the angles of said pair, to pull them towards each other .

The at least partial solution proposed here consists in that the traction element comprises an elastic element.

Preferably, each angle has, in the angle, an outgrowth, i.e. a protrusion, external to place the elastic member, this protrusion being provided with a retaining rim.

Thus, it will make both fast and convenient setting up and withdrawal.

In a first embodiment, the traction element comprises an elongated rigid frame bearing against its opposite ends on the brackets of the pair to pull them towards each other.

This will provide strength and stiffness of maintenance. Preferably, each angle then has a through passage extending in the direction in which extends the elongate rigid member connecting the pair of angles concerned and on the side walls of which the frame will be supported by means of adjustment lengthways.

Also concerned is a polygonal box comprising:

- sidewalls each having, near at least one upper or lower edge of each face, an end portion which comprises there a batten and an adjacent post disposed substantially perpendicular to each other,

and a plurality of pairs of angles which, along each of their two outer lateral partitions, respectively receive the uprights and the adjacent slats, these pairs of angles being those each provided with a said traction element, the assembly device shown in FIG. high .

For the protection and safety of the contents and the maintenance of the angles, crate mounted, it is preferable that the body comprises a lid arranged to cover an upper opening that the side walls define between them, towards the top of the box, and the upper angle of each pair of brackets covers said lid at an angle of the box.

For the same purpose and for handling, it is expected that the box may include a pallet on which stand the side walls, each bottom angle of pairs of angles being fixed to the pallet, above it.

To promote speed and ease of implementation and removal, and a free internal volume gain for loading, it is recommended that the traction element, or each of them, be disposed outside the corners of the box.

For a stable box and sufficiently resistant mechanically, it is recommended that each corner element has, between each outer side wall and an inner wall erected internally (an inner side wall), at a distance, substantially parallel to it and the along which is disposed at least one polygonal pillar of section greater than the thickness of the partition and which stands in the space between the inner side wall and the outer side wall to define:

a first volume in which the amount of the relevant lateral wall of the body is received, which is thus engaged against the internal lateral partition, and

- A second adjacent volume where is received the adjacent slat which is thus engaged substantially against said outer side wall.

Thus, it is not necessary to notch the slats concerned, unlike the solution of FR2805521 where the partitions form transverse structures vis-à-vis the space which, moreover, they limit the volume. However, cooperation between notches in the walls of the box and transverse reinforcements in the angles can contribute to a better hold in position of angles and walls.

For the strength and stability of the device provided with these angles, it is recommended that the inner side walls meet near said first angle of each angle, at the corner of a corner where a connecting wall and stop for the walls of the body joined a polygonal corner pillar which stands against said outer side walls.

To promote a gain of free internal volume for the loading of crates, it is recommended that the bottom of each corner element has a substantially triangular shape and is, on the side where the partitions stand and on its part located at outside the first and second volumes, devoid of any erect structure rising to a height greater than a quarter of that of the partitions.

To facilitate a stack of crates, it is further recommended that, on the opposite side to that where the side walls rise, the bottom of the angles is bordered by abutment walls that converge towards the said first angle and calent in the corners the boxes superimposed.

In addition, the operation of these boxes will be even easier if each abutment wall is extended by a guide edge inclined outwardly and a height less than that of the abutment wall.

For stability, it is recommended that the abutment walls extend the side walls. outside, just outside edge of the angles, on the opposite side of the bottom.

For the same purpose, it is recommended that the first angle of the angles be truncated and that these angles are devoid of guiding edge and / or that the abutment walls are connected in the corner by a wall of erect angle of lesser height.

For the resolution of at least some of the problems mentioned above, is still proposed an angle, having spaces oriented in two directions and adapted to receive walls of a box with which the angle is suitable for assembly, each space being delimited by at least one outer side wall and an inner side wall, and said bracket further having a protrusion, an outer projection provided with a retaining flange for attaching a traction element to bring one of the other two angles of this type.

It is not meant "outside" that the protrusion is located on the visible surface when the angle is assembled with walls of a box for example. Advantageously, this protrusion is located at the junction of the outer side walls, in the corner they form.

Preferably, it also has a lug provided with a transverse retaining zone, said lug being adapted to engage in a slot parallel to an edge of a wall of the box and to be retained by abutment of its seat. transversal area, the paw and its area transversal retaining thereby forming a fastening clip.

In this case, transverse means the fact that the retaining zone extends in a transverse direction, or even orthogonal, to a direction of the tab.

Thus, the use of brackets jointly having an outer protrusion provided with a retaining flange and at least one fastening clip allows both to assemble and dismount a box easily and quickly, without the need for tools. specific. When the body is dismantled and folded, it is easily transportable and all the elements that make it together and held together. The presence of clip is not essential when the body is folded, but it becomes very useful when mounted, for the strength of the structure, and for safety, especially if a traction element became defective, for example, if the traction element was breaking. In addition, when the body is mounted, the joint presence of the clips and excrescences which are hung traction elements makes it possible to solidify the body, and very easily guarantee a good alignment of the assembly, ie so that the side walls of the body crate be straight for example. This allows, especially if several boxes are stacked, to ensure that a cover (if the fund is provided) extends horizontally; thus a stack of cases is more stable.

Advantageously, the transverse retaining zone of one of the lugs has an asymmetrical shape, for example example in the form of a knife blade, which facilitates the insertion and extraction of the tab for fixing the angle and its voluntary withdrawal.

According to an advantageous embodiment, particularly in the case where the tab considered is an inner lug, i.e. integral with an inner partition, at least one of the tabs has a hooking zone.

According to another advantageous embodiment, the outer side wall of at least one oriented space of the angle has at least one leg and the inner side wall of the same oriented space has at least one leg, so that the leg the inner sidewall is longer than the outer sidewall tab.

Preferably, the two outer side walls each have a tab. This embodiment thus allows the simplest implementation.

According to another embodiment, the two inner side walls each having a tab. If the tabs are only present on the internal partitions, this allows to have a bracket whose removal is more difficult, which ensures better tamper content.

If tabs are present on the inner walls in addition to legs present on the outer walls, then the benefits are cumulative. In the latter case, it is preferable that the tabs of the inner side walls are longer than the tabs of the outer side walls. Indeed, as stated above, this makes it possible to disengage choice, inner or outer legs first, the slots of the inner legs then to be tranversante.

Preferably, an angle according to the invention comprises a bottom wall, transverse to the inner and outer side walls, forming a bottom stop.

According to an advantageous embodiment, and even more advantageously when the bracket comprises inner legs provided with a hooked area, the bottom wall has a perforated area.

According to another advantageous embodiment, each space has at least one transverse reinforcement at least one of the inner and outer side walls adapted to cooperate with a slot orthogonal to an edge of the wall and opening to ensure the relative positioning of the side wall of the box and the angle. Preferably, each transverse reinforcement is orthogonal to at least one of the partitions, which allows the angle to be produced by molding without requiring machining. The transverse reinforcement and the orthogonal slot thus have complementary orientations to insert the reinforcement into the slot.

These transverse reinforcements make it possible to stiffen certain parts of the structure. They are however profiled so as to confer, despite their presence, enough flexibility to the angle to facilitate the insertion or extraction of the legs. It is then necessary that vertical and emergent slots are formed in the walls of the box so as to receive these transverse reinforcements. They also allow to once again ensure the positioning of the angle.

In addition, it is also advantageous that the angle has at least one rib capable of sinking into the wall for wedging, to compensate for possible play. This rib preferably has a conical shape so as to drive it more easily into the wall during the insertion of the angle.

The present invention also provides a device for assembling a box comprising side walls, and comprising at least a first and a second angle as defined above, and a traction element adapted to connect the first and the second angles being hooked to their outer outgrowth.

Preferably, the traction element comprises an elastic element, which makes it possible to connect the first and second angles via their external protrusion.

Finally, the present invention also relates to a dismountable mounted crate comprising at least one side wall, and the following constituent elements may be assembled reversibly, i.e. can be separated to dismount the box:

at least one assembly device as defined above,

at least a third and a fourth angle as previously described, the side walls of the box being assembled with the angles, and a pallet, forming a bottom wall at the box. The box is thus devoid of any other means of maintenance to assemble the box in a unitary unit.

According to a preferred embodiment, the first and second angles define lower angles fixed to the pallet at two adjacent corners of the pallet, the third and fourth angles define upper angles, the side wall is assembled with the two lower angles and the two upper angles, and the traction element interconnects the first, second, third and fourth angles. Thus, to secure and lock the assembly of a box, only two tie rods are needed. In addition, if the box is rectangular, that is to say that it comprises four walls whose two facing walls are longer than the other two, it is preferable that the tie rods connect the four angles located at the four corners of the longest walls, so that the tension in the tie rods is greater. Thus the assembly is more robust.

Advantageously, at least two brackets are fixed to the pallet, for example by nails, glue, or staples. Fastening angles to the pallet makes it possible to limit the number of actions to be performed during assembly or dismantling of the box.

Advantageously, the wall of the box has at least one slot orthogonal to the edge of the side wall and opening. Thus, the wall is adapted to receive a transverse reinforcement to at least one of the internal and external side walls when the angle is provided.

Preferably, a wall of the body comprises at least one slot parallel to an edge of the side wall, to receive a transverse retaining zone of a tab. If there is no horizontal slot, then the angle must be dimensioned so that the retaining cross-zone comes to grip under a lath constituting the wall.

Advantageously, the body, which comprises a plurality of side walls, comprises a lid arranged to cover an upper opening that the side walls of the body define between them. The presence of a lid is preferable to protect and isolate the contents of the box when it is filled.

Finally, the present invention is directed to an assembled dismountable box comprising at least one side wall and the following constituent elements that can be assembled in a reversible manner, i.e. that can be separated to assemble the box:

at least one assembly device as defined above,

at least a third and a fourth angle as previously described, and

a pallet, forming a bottom wall at the body, and the packaging device being such that the first and second angles define lower angles fixed to the pallet, the third and fourth angles define upper angles. placed on the pallet, at least one side wall for forming the body is laid supine, flat, on the pallet, preferably above the brackets, and the pull element interconnects the first and second angles.

Advantageously, the two lower angles fixed to the pallet are fixed at two non-contiguous corners of the pallet, for example diagonally opposite for a square or rectangle pallet, which then makes it possible to attach the tie rods in a cross to provide better maintenance of all elements together.

Thus, for a box with four walls, two tie rods are necessary. Each tie then connects two lower angles fixed to the pallet via their outgrowth. The tie rods are crossed so that all the elements can be held together when the box is dismantled.

Advantageously, the four side walls of the box are laid flat and crosswise on the pallet, that is to say crossed two by two, preferably above the upper angles, which have been previously detached, for keep them in place.

The cooperation of these various elements thus leads to a packing device of a box allowing its assembly in less than 2 minutes.

In addition, such a device facilitates the recycling of items and for example the consignment of boxes.

The invention, according to a preferred embodiment, will be well understood and its advantages. will appear better on reading the detailed description which follows, by way of indication and in no way limiting, and with reference to the accompanying drawings presented below:

The identical elements shown in FIGS. 1 to 35 are identified by identical reference numerals.

A box, as illustrated, is polygonal, preferably four sides. It comprises four walls 3, a pallet 5 and a lid 4, these different elements being connected to each other by means of four upper angles 1 and four lower angles 2. Thus, an upper angle 1 and a lower angle 2 can constitute a pair angles. The box is for example rectangular, two of the walls 3 are longer than two others which are perpendicular to them.

Advantageously, a cover 4 is arranged to cover the upper opening that the side walls 3 define between them, towards the top of the box. The upper angle 1 of each pair of angles covers the lid at an angle of the box, thus ensuring its retention. This will avoid the traditional bands of strapping.

In Figure 1, the box is in assembly configuration, soon ready to receive one or more objects in its interior volume delimited by the side walls 3 erected on the pallet 5, the periphery thereof with, to each angle, an angle bracket 1 or higher 2.

According to the present example, the walls 3 are made of wood and slatted. However, all forms and materials would be suitable here. [00104] Likewise, a pallet 5 is typically a wooden element, but any type of base or support capable of receiving a box would be suitable.

The pallet 5 can comprise a base comprising a series of feet (not shown) which 1 'separate from the ground or several (here three) rafters 51 surmounted by a plate 52 adapted to the shape given by the walls 3.

Here, the plate 52 is rectangular and forms a preferably solid and flat bottom for the body. Each side wall 3 is here slatted. Each side wall 3 comprises several (here three) slats 32 horizontally elongated and placed one above the other, spaced apart, and several (here two) vertical uprights 33 interconnecting the lateral ends of the slats 32.

The slats 32 and the adjacent amounts 33 associated are perpendicular to each other on each side of the body. They can be wooden and fixed together, for example by nails. As illustrated, the uprights 33, a priori all identical, have a rectangular or trapezoidal section and are arranged inside the box with respect to the slats 32.

On each side wall 3, the uprights 33 extend from the lower edge 321 of the lower batten 32 to the upper edge 322 of the batten 32 upper.

Therefore, at the location of the lower end of a wall, the lower edge of each side wall 3 is formed by the lower edge 321 of the corresponding lower batten 32 and the ends longitudinal lower 33 corresponding amounts. In addition, this lower edge is substantially rectilinear along the side wall 3 considered, which thus has in particular no part projecting downwards.

In contrast, at the location of the upper end portion, the upper edge of each side wall 3 is formed by the corresponding upper edge 322 of the upper slats 32 and the upper longitudinal ends of the uprights 33. This end upper is also substantially rectilinear along the side wall 3, without projecting portion upwards.

Preferably, a box is assembled with a set of upper angles 1 all identical to each other and a lot of lower angles 2 all identical to each other. The upper angles 1 and lower 2 can also be all identical to each other, but not necessarily. It is thus possible to differentiate between the lower and upper angles 1. Thus, the upper angles 1 may have or not guide walls 14, for example.

Each angle (1, 2) will be favorably monobloc, i.e. in one piece, and plastic, such as polypropylene, and for example injection molded.

However, there are different embodiments of the upper angles 1 or lower 2.

According to a preferred embodiment, the walls have at least one slot 31 adapted to receive a tab (111, 121, 211, 221) of an angle (1, 2), when these legs are not long enough to be able to come to grip the slats of the box for example.

Whatever the embodiment, an upper angle 1 has spaces oriented 15 in two transverse directions and adapted to receive the relevant walls 3 of the box with which the angle 1 is to assemble. Each space 15 is open on at least one side, and delimited on two other sides by an outer side wall 11 and an inner side wall 12.

To receive in a wedged manner the relevant side wall 3 of the box, each partition 11 of the angle 1 considered is thus doubled internally, remotely, by the inner side wall 12 which stands substantially parallel to it.

These outer lateral partitions 11 converge to a first angle 18 of the angle.

Here, the angle 18 is a right angle, preferably truncated.

The upper angles 1 may also have different structural reinforcement elements 16 as is customary in this type of technology. Reinforcements 16 also contribute to the proper positioning of the relevant walls 3 of the box with which the angle 1 is to be assembled.

The reinforcing elements of structure 16 are advantageously constituted by a polygonal pillar, against an inner side wall 12. These pillars are a priori identical. They are preferably rectangular. They serve as reinforcement and limitation of the space 15, to receive against them (and wedge) the walls of the box. Their section is equal to about half the width "i" of said space 15, to define two spaces between the inner side wall 12 concerned and the outer side wall 11 it comes to double.

Thus, the two adjacent and communicating volumes allow to receive the battens 32 and 33 amounts concerned. It is preferred that the bearing faces are perpendicular to each other.

The pillars 16 therefore longitudinally limit the first volume, receiving, the amount 33 concerned. These pillars 16 are raised here towards the end of these volumes, opposite the first angle 18. At this end the second volume is open at 150.

At its longitudinal end close to the angle 18, and therefore opposite to the open one 150, this second space is advantageously limited by a partition 114 and, in alignment, by a portion 124 extending the partition 12. It is possible to thus consider that the partitions 114 delimit a corner pillar 181.

Each upper corner 1 preferably has a partition 13 extending transversely to the inner side walls 12 and outer 11, forming a bottom stop. The bottom 13 is advantageously a solid plate, but may include perforated zones.

Thus, along each outer side wall 11, and in abutment against the bottom 13, will be able to be received, substantially parallel to the partition 11, a side wall 3 of the body. In the illustrated embodiment, it is the end portion of one of these side walls 3 which therefore comprises there, disposed substantially perpendicularly to one another, a slat 32 and an associated adjacent amount 33.

Preferably, the upper face of the transverse partition 13 of an upper angle 1 has antiskid pins 131 with, preferably, a pointed end, which thus contribute to the maintenance in position of a superimposed body.

According to one embodiment (for example illustrated in Figure 12), an upper bracket 1 has two outer legs 111 each joined to an outer side wall 11 and two inner lugs 121 each joined to an inner side wall 12.

Each lug (111, 121) is provided with a transverse retaining zone (112, 122). Thus, each tab (111, 121) is adapted to engage a slot 31 formed in a wall 3 of the box and be held there by abutting its transverse area (112, 122).

In Figure 12, the inner lugs 121 have a shape giving them more elasticity than the outer legs 111. Indeed, such a shape can facilitate disassembly of the assembled box. The inner lugs 121 then preferably have a hooked area 123, in this case a hole. A hooked area 123 may, for example, be used to insert a tool to facilitate the disengagement of the inner lug 121 to remove the upper angles 1. In this case, the transverse partition 13 also preferably has perforated zones 132. The perforated zones 132 allow the insertion of a tool to engage the hooked zones 123.

According to this embodiment of an upper angle 1 of this transverse partition 13 stand: on the side of its lower face the outer 11 and inner 12 outer partitions, and, where appropriate, the side of its upper face a guide wall 14. Preferably, the guide wall 14 is in the extension of the outer side walls 11 of the upper angle 1. Preferably, the guide wall 14 has a slightly flared shape, ie with an inclined edge outwardly and a height h2 less than that h3 of the guide wall, facilitating the positioning of an element (for example another body) which would be superimposed on the body, thus promoting its wedging.

An angle having a guide wall 14 could of course be used as a lower angle, but the guide wall 14 would then lose its usefulness, or make the assembly much less convenient.

[00133] It can further be provided that, if the first angle (18, 28) is truncated, the angles there are devoid of guide walls 14, or preferably, that these guide walls 14 are connected in the corner by a upright corner wall, of lower height.

It will also be noted that the bottom (13, 23) has at this location a substantially triangular shape and may be, on the side where the partitions (11, 21, 12, 22) stand and on its part located at the outside the first and second volumes (15a, 15b; 25a, 25b), devoid of any erect structure rising to a height greater than a quarter of that of said partitions. There may be no such erect structures at all, which will further free up the space available for loading the crate.

In this embodiment, it is then preferable, when tabs (111, 121) are present both on the inner 12 and outer side walls 11 of the angle 1, that the inner lugs 121 of the inner side walls. 12 are longer than the outer legs 111 of the outer side walls 11.

Indeed, it is possible to remove an inner lug 121 by inserting, as far as possible, a tool in the hooked area 123 through a perforated area 132, but it is also possible to remove a leg 121 by inserting a tool in the slot 31 (which must then be through) which retains its transverse area 122 and pushing it inwardly of the box. In this case, it is then necessary for the inner lugs 121 to be longer than the outer lugs 111. This length also contributes to giving them greater elasticity.

According to another embodiment (for example illustrated in FIG. 13), an angle bracket, upper 1 or lower 2, has only two external lugs 111 each joined to an outer lateral partition 11, and provided with a transverse zone of retaining 112, adapted to engage a slot 31 in a wall 3 of the body. The outer leg 111 is then retained by abutment of its transverse zone 112. The perforated zones 132 are then not necessary.

In this embodiment, an upper bracket 1 or lower 2 also has no guide wall 14.

However, it goes without saying that an upper bracket 1 may have a guide wall 14 and have only outer legs 111 or inner lugs 121, or have no guide wall 14 having legs internal 111 and outer 121.

[00140] If an upper bracket has only inner lugs 121, with or without guide wall 14, it becomes altogether preferable that the inner lugs 121 have hooked areas 123 and that the transverse partition 13 has perforated zones 132 to facilitate the removal of these elements during dismantling of the body. Or, the slot 31 in which engages an inner lug 121 is preferably through to facilitate the insertion of a tool to push the clip when removing the angle.

A lower angle 2, shown for example in Figure 11, has oriented spaces 25 in two transverse directions and adapted to receive walls 3 of a box with which the angle 2 is intended to be assembled.

Each space 25 is delimited by an outer lateral partition 21 and an inner lateral partition 22. The outer lateral partitions 21 converge towards a first angle 28 of the lower angle 2.

Here, the angle 28 is a right angle, preferably truncated.

[00145] The lower angles 2 may also have different structural reinforcement elements 26 as is customary in this type of technology. Reinforcements 26 also contribute to the proper positioning of the relevant walls 3 of the box with which the angle 2 will be assembled.

The reinforcing elements of structure 26 are advantageously a polygonal pillar, against an inner side wall 22. These pillars are a priori identical. They are preferably rectangular. They serve as reinforcement and limitation of the space 25, to receive against them (and wedge) the walls of the box. Their section is equal to about half the width "i" of said space 25, to define two spaces between the inner side wall 22 concerned and the outer side wall 21 it comes to double.

Thus, two adjacent and communicating volumes will allow to receive slats 32 and 33 amounts concerned. It is preferred that the bearing faces are perpendicular to each other.

The pillars 26 therefore longitudinally limit the first volume, receiving there, the amount 33 concerned. These pillars 26 are raised here towards the end of these volumes, opposite the first angle 28. At this end the second volume is open at 250. At its longitudinal end near the angle 28, and therefore opposite to that 250 open, this second space is advantageously limited by a partition 214 and, in alignment, by a portion 224 extending the partition 12. It can be thus consider that the partitions 214 delimit a corner pillar 281.

[00150] Each lower angle 2 has for example two tabs 211 each joined to an outer side wall 21 and two tabs 221 each joined to an inner side wall 22.

Each lug (211, 221) is provided with a transverse retaining zone (212, 222). Thus, each tab (211, 221) is adapted to engage a slot 31 in a wall 3 of the box and be held there by abutting its transverse area (212, 222).

As for the upper angles 1 according to the first embodiment, it is preferable, when tabs (211, 221) are present both on the inner 22 and outer side walls 21, that the inner legs 221 of the inner side walls 22 are longer than the outer legs 211 of the outer lateral partitions 21.

Each lower angle 2 also has a transverse partition 23 to the outer lateral walls 21 and 22, forming a bottom stop. The bottom 23 is advantageously a solid plate.

The transverse partition 23 then comprises at its upper face, the outer and outer side walls 21 and 22. At its face lower, the transverse partition 23 may, for example, have junction elements with the pallet 5, for example nails (not shown here).

Thus, along each outer side wall 21, and abutting against the bottom 23, will be received, substantially parallel to the partition 21, a side wall 3 of the body. In the illustrated embodiment, it is the end portion of one of these side walls 3 which therefore comprises there, disposed substantially perpendicularly to one another, a slat 32 and an associated adjacent amount 33.

To receive in a wedged manner the relevant side wall 3 of the box, each partition 21 of the angle 2 considered is thus doubled internally, remotely, by the inner side wall 22 which stands substantially parallel to it.

An upper bracket 1 according to the embodiment of Figure 13 for example, can both constitute an upper bracket and a lower bracket. In addition, an upper bracket 1 according to this second embodiment is similar to a lower bracket 2, shown in Figure 11 for example, but which would not include inner legs 221. In this case, it is possible to assemble a box with angles all identical, indifferently lower or higher.

According to the exemplary embodiments shown, a tab 121 of FIG. 12 is more easily elastically deformable than a tab 211 or 221. However, all the tabs (111, 121, 211, 221) may have the same shape as the tab 121 of FIG. Similarly, only the tab 121 has a hooked area 123, but all the legs (111, 121, 211,

221) could have a hooked area, such as a hole, to facilitate their extraction from the corresponding slot 31.

[00160] The transverse retaining zone (112, 122, 212,

222) of a tab (111, 121, 211, 221) may also have an asymmetrical shape, for example in the form of a knife blade as the transverse zone 112, which makes the insertion and extraction of angles easier .

According to the examples shown, the transverse retaining zones (112, 122, 212, 222) of the tabs (111, 121, 211, 221) facing each other, for example 222-212 or 122-112, leave between them a space, visible in Figures 11c) and 12c) for example. Nevertheless, these transverse retaining zones (112, 122, 212, 222) could be wider, which would produce an overlap of the outer legs (112, 212) by the inner lugs (122, 222) without affecting the operation of 1 invention.

The shape of the upper angles 1 and lower 2 allows to superpose the boxes which facilitates their transport and storage. For example, the upper angles 1 are able to receive the pallet 5 of another box.

According to other embodiments shown in Figures 14 to 17, an angle (1, 2) has inner lugs (121, 221) and / or outer (111, 211), provided with a transverse retaining zone (112, 122, 212, 222) adapted to engage the edge of a slat a wall 3 of the body and be retained by abutment of its transverse area (112, 122, 212, 222).

Similarly, the transverse retaining area (112, 122, 212, 222) of a tab (111, 121, 211, 221) may have an asymmetrical shape, for example in the form of a knife blade. The inner legs may have a shape giving them more elasticity, such as the shape of the tab 121, which facilitates disassembly of the assembled box. Such a tab then preferably has a hooked area 123, in this case a hole, which can be used to insert a tool to facilitate the disengagement of the tab and remove the angle.

In this case, the transverse wall (13) advantageously has a perforated zone 132. The perforated zones 132 allow the insertion of a tool to engage the hooked zones 123.

It is also possible to remove an inner lug (121, 221) by pushing the transverse zone (122, 222) gripping a lath of a wall towards the inside of the box.

It goes without saying that an upper bracket 1 may have a guide wall 14 and comprise only external lugs 111 or inner lugs 121, or outer lugs 111 and inner lugs 121, or not present. guide wall 14 having inner lugs 121 and / or outer lugs 111.

When long legs (111, 121, 211, 221) are present both on the inner (12, 22) and outer (11, 21) side walls, it is preferably that the inner lugs (121, 221) of the inner side walls (12, 22) are longer than the outer legs (111, 211) of the outer side walls (11, 21).

When an angle is used as a lower angle 2, it is advantageous that the transverse wall 23 then comprises at its outer face, for example, junction elements with the pallet 5 (not shown here).

Similarly, it goes without saying that a lower angle 2 may have connecting elements with the pallet 5 and comprise only external legs 211 or that inner lugs 221, or both outer legs 211 and internal lugs 221, or not having junction elements with the pallet 5 having inner lugs 221 and / or outer 211.

The use of long legs has mainly the advantage of not having to machine slot 31 in the walls of the box.

[00172] Favorably, each angle (1, 2) then has, in the angle (18, 28) considered, an outgrowth (or projection) outside (19, 29) to place the elastic element 6. This protrusion is preferably provided with a retaining rim preventing the elastic element 6 from sliding unexpectedly.

It (19, 29) allows, for example, to connect together an upper angle 1 and a lower angle 2 so as to form a pair, with a traction element 6, thus bringing them closer to one another. on the other (here to pull them towards each other). To limit the interior space synonymous with lost space for loading, it is preferable that each traction element (6, 7) is disposed outside the corners of the box. Each extends (vertically) over the height of the box, between the upper and lower angles 1 and 2 of the pair considered.

According to a preferred embodiment, the traction element comprises an elastic element 6. It may be extensible rubber.

According to another embodiment, illustrated in Figures 25 to 27, the traction element may comprise an elongated rigid frame 7 mounted to rotate on the brackets (1, 2) of the pair. This frame 7 is provided with length adjustment means 71 spaced along its length and which bear on the angles, depending on the angular position of the frame 7, to pull them towards each other.

For this, each angle (1, 2) favorably has a through passage (17, 27) extending in the direction (here vertical) of elongation of the frame 7 mounted on the body, between the angles 1 and 2 (see for example the angles of Figures 18 and 19). By means 71 of length adjustment, the frame 7 thus bears on the periphery of the passage (17, 27). This frame 7 may be a screw and the periphery may be provided with cooperating threads. A maneuvering tip can facilitate the rotation of the frames 7. Mounted on the boxes, these frames will not exceed respectively below or above the brackets (1, 2) of the pair considered. In this chord solution, each through passage (17, 27) will be favorably made in the immediate vicinity of the first truncated angle (18, 28) concerned, so that the rigid chord 7 passes through the corner pillars (181). , 281).

The corner pillars (181, 281) are raised against said partitions (114, 214), in the truncated angle, on a height which may be that of the partitions (11, 12). These corner pillars (181, 281) are here triangular.

As for the internal partitions (12, 22), they meet near this first angle (18, 28), at the location of a corner (120, 220) where a partition (124, 224) ) of connection and abutment for the side walls 3 of the box joined the pillar (181, 281). The partition (124, 224) is bent, here at right angles, to limit longitudinally, at one end, the two volumes (15a, 15b, 25a, 25b) constituting the spaces (15, 25) of the angle considered that are open (downwards for the upper corners 1 and upwards for the lower corners 2).

To promote the equilibrium of the assembly, the protuberance (19, 29) is preferably made at a sloping wall connecting between said adjacent outer side walls (11, 21). The protrusion (19, 29) may for example be half-height H / 2 of the partition (see Fig. 20b).

To further strengthen the wedging angle and robustness of the assembly of a box, brackets (1, 2) may also include conical ribs 8, as illustrated in Figures 28 and 31 in particular. In the embodiment shown, a conical rib 8 is present on a transverse reinforcement 9, and three conical ribs 8 are present on an inner side wall. These ribs 8 could of course be positioned on any partition of the angle, as they sink into the walls of the box during the establishment of the angle.

In the embodiment shown, each of the two transverse reinforcements 9 is orthogonal to the inner and outer partitions of the oriented space in which it is present.

Thus, the angles may comprise transverse reinforcements 9 to stiffen certain parts of the structure. These transverse reinforcements 9 are profiled so as to confer, despite their presence, enough flexibility to the outer side walls to facilitate the insertion or extraction of the legs when the outer side walls are provided. It is then necessary for vertical slots 34 and outlets to be formed in the walls of the box so as to be able to receive these transverse reinforcements 9. They also make it possible to ensure once again the positioning of the corresponding angle.

Thus, an upper angle 1 and a lower angle 2, both provided with an external protrusion (19, 29) form a pair of angles capable of cooperating with an elastic traction element for packaging (for storage for example) and the assembly of a box, for example as shown in Figures 32 to 33. The angles of a pair of angles can also include ribs 8, tabs provided with transverse retaining zones, guide walls, etc. These characteristics can thus be adjusted according to specific needs.

In this case, the angles of the device for assembling a removable box and its packaging when disassembled, have fastening clips on the outer side walls capable of engaging horizontal slots 31 formed in the walls of the box, an external protrusion, conical ribs 8 and transverse reinforcements 9 adapted to engage vertical emergent slots 34 formed in the walls.

A demountable box as illustrated then comprises the following components that can be assembled in a reversible manner:

^■ four pairs of angles and two elastic traction elements, ^■ a pallet 5, forming a bottom wall at the body,

^■ four side walls, having horizontal slots 31 and vertical 34 so as to receive clips and transverse reinforcements 9.

[00190] Thus, when the body is mounted, the lower angles are fixed to the pallet, the walls and angles are positioned as it should, and each of the tie rods connects two lower angles and two upper angles. When the body is dismantled, the pairs of angles and tie rods serve as a packaging device.

The lower angles are always attached to the pallet 5, but the upper angles are now placed on the pallet 5, and the four walls 3 for forming the body 3 are laid, lying flat on the pallet 5, and crossed . The two tie rods then connect between them two diagonally opposite lower angles, so that they form a cross above the walls 3 lying, which allows to maintain all the elements.

The present invention thus makes it easy to stack the crates, mounted or dismounted.
