Description

The technical sector of the present invention is that of packaging assemblies in the form of a box for receiving various parts or components to be delivered.

Numerous embodiments have been proposed, for example FR-2805521, FR-2956384, FR2643335, US-5415310, EP-0089017. Patent FR-2805521 proposes a dismountable box comprising a pallet on which lower corner elements are fixed to receive in a simple downward movement of the side walls and upper elements for fixing the walls together. The disadvantage of this. realization lies in the fact that the rigidity of the body is low because it can be disassembled by a simple traction on a wall. In addition, the fund has a very insufficient level of security. FR-2956384 discloses corner elements to enhance the rigidity of the assembly. US-5415310 discloses a crate whose side walls can be individually assembled. EP-0089007 discloses a trunk consisting of a base assembly comprising a bottom and four side walls, two consecutive walls being connected by brackets to connect said walls to each other, fixing means being provided between the bottom and each side wall, the assembly being completed by upper corners capping the walls in pairs. The main disadvantage of this trunk lies in its complex realization which requires several interventions and a large assembly time. The object of the present invention is to provide a box which can be assembled and disassembled very quickly from a kit without any tools. The subject of the invention is therefore an assemblable box consisting of at least one bottom, two longitudinal side walls, two transverse side walls and four top corners, characterized in that the bottom is provided at its transverse edges. retaining means for blocking each of the transverse walls on the bottom by means of wedges fixed to said transverse walls, said transverse walls being held in the corresponding retaining means by means of said wedges engaged by horizontal translation, the two opposite longitudinal walls being free with respect to the bottom, each of the longitudinal walls being provided with a stop cooperating with the abutment of the adjacent transverse wall in order to prevent any upward movement of the longitudinal walls with respect to the transverse walls, each upper corner being supported on two adjacent walls. According to a feature of the invention, the lateral transverse walls comprise two vertical uprights at the lower ends of each of which is fixed a wedge. According to another characteristic of the invention, the bottom is provided with cleats along its longitudinal edges intended to prohibit the displacement of the longitudinal walls to the outside. According to another characteristic of the invention, the internal space of each retaining means extends in one direction along a transverse edge, while each batten extends perpendicularly to this direction along a ridge. longitudinal. According to yet another characteristic, the retaining means is constituted by a profile in the form of a U, one wing of which is extended by a flap parallel to the base of said U. According to yet another characteristic, the profile is disposed totally or partially along each of the transverse ridges. According to yet another feature, the box has four sections each disposed at the ends of the transverse edges. According to yet another characteristic, the profile defines an internal space shaped to the dimensions of each shim bearing against the flap. According to yet another feature, the retaining means is metallic. According to yet another feature, the longitudinal and transverse side walls are in the form of frames.

According to yet another feature, the upper corners are in the form of a hollow part comprising at least one cover and two L-shaped arms delimiting an internal space. According to yet another characteristic, the internal space 10 is shaped to that of the corresponding upper part of each longitudinal and transverse side wall. According to yet another feature, the upper corners are each provided with at least one lug for limiting the movement of a body relative to another during their superposition. According to yet another characteristic, during the assembly of the side walls, the horizontal bars and the vertical uprights of the longitudinal side walls bear respectively with the horizontal bars 20 and the uprights of the transverse side walls to form a nesting of these walls. A first advantage of the present invention lies in the fact that the body according to the invention is a rigid assembly little deformable. Another advantage is the ease of mounting the box without any tools by one person. Another advantage of the invention lies in the locking of two walls on the bottom and the locking of the other two walls on the previous two. Yet another advantage of the present invention lies in the presence of a lug which translational immobilization of one body relative to the other when superimposed. Yet another advantage of the invention is its simplicity of construction. Other features, advantages and details of the invention will be better understood on reading the additional description which will follow of embodiments given by way of example in relation to drawings in which: FIG. 1 is a side wall and FIG. 3 is the adjacent side wall; FIG. 4 is an assembled box; FIG. 5 is a view of the box; FIG. Figure 6 is a cross-sectional view of the retainer, Figure 7 is a view of the upper wedge, and Figure 8 is a further view of the upper wedge. In the exploded view of FIG. 1, different constituents of the body 1, namely the bottom 2, the longitudinal lateral walls 3 and 4, the transverse side walls 5 and 6, the upper corners 7-10 and the means 13. It is obvious that the longitudinal and transverse designations are distinguished to clarify the understanding of the invention and not to limit its scope. In the remainder of the description, reference will be made hereinafter indifferently to longitudinal and transverse walls and to longitudinal and transverse edges without reference to the length of these walls and edges. There are shown here four retaining means 13 fixed at the transverse edges 11 and in the vicinity of the ends of the longitudinal edges 12 of the bottom 2. It goes without saying that the retaining means could be made in the form of a single piece in one piece and of appropriate length at each transverse edge. Four cleats 34a-34d (the cleat 34d is not visible in this figure), of appropriate length, are arranged in the vicinity of each retaining means 13 along the two longitudinal edges 12 of the bottom 2 and are aligned therewith. In the figure, it can be seen that two cleats 34 are provided along a longitudinal edge 12, but it goes without saying that it would be possible to provide a single cleat of a different length. The role of these cleats will be explained in the following description. The longitudinal walls 3 and 4 are provided on either side respectively of the abutments referenced 16a or 16'a and 16b or 16'b and the transverse walls 5 and 6 respectively of the abutments referenced 15a or 15'a and 15b or 15 ' b. These stops are arranged so as to prohibit any relative movement of the walls relative to each other when they are positioned on the bottom 2, as will be explained below. The bottom 2 is in the form of a pallet, but it goes without saying that it could be made in any form provided that it can be handled by a forklift. It can be made of wood or any other suitable material. The longitudinal and transverse side walls 3-6 are here in the form of a frame stiffened by vertical uprights and a transverse bar fixed on these uprights. Of course, these walls are made using wooden planks but they can be made of any other suitable material. The transverse lateral walls 5 and 6 are each provided at their base with shims 30a and 30b near their end and positioned at a small distance, referenced e, of the lower bar 14a. These wedges are intended to cooperate with the retaining means 13 so as to fix the transverse walls 5 and 6 on the bottom 2. It goes without saying that the wedges 30a and 30b are fixed at the lower end of the uprights 31a and 31b. It is still seen in this figure that the longitudinal walls 3 and 4 are of greater length than the transverse walls 5 and 6. It goes without saying that the lengths can be modified according to the needs of users and the dimensions of the equipment intended for be packed. FIG. 2 shows a flat view of the transverse wall 3, of identical structure to the transverse wall 4, consisting of at least one frame formed by the four vertical uprights 25a-25d and horizontal end bars. lower 26 and upper 27. These elements are nailed or screwed together by appropriate means. This frame is stiffened by a transverse bar 28 connecting diagonally the four uprights 25a-25d. In the plane of the figure, it can be seen that the lower end of each upright 25a-25d protrudes from the lower edge of the lower bar 26.

The lower horizontal bar 26 can thus come slightly above the cleats. We also see that the upper end of the outer uprights 25a and 25d, is flush with the upper edge of the upper bar 27. It can be seen that the upper end of the intermediate uprights 25b and 25c is set back from the upper edge of the upper bar 27. We also see that the ends of the lower bar 26 and upper 27 exceed relative to the uprights 25a and 25d outside. The frame of the longitudinal wall 3, 4 can be completed by a plate 37 fixed between the intermediate uprights 25b and 25c and on the lower and upper bars 27. The stops 16a and 16b protrude laterally each relative to the amount on which they are fixed. FIG. 3 shows a flat view of the transverse wall 5, of identical structure to the transverse wall 6, consisting of at least vertical uprights 31a and 31b, horizontal bars 14a and 14b and a crossbar 29 connecting diagonally the uprights 31a and 31b. These elements are nailed or screwed together by appropriate means. In the figure, we see that the transverse walls 5 and 6 are of shorter length than the longitudinal walls 3 and 4 and we still see the high disposition of the stops 15a and 15b. We can still see the wedges 30a and 30b respectively fixed on the uprights 31a and 31b at a small distance, referenced e, of the lower bar 14a. It can be seen that the lower end of each upright 31a 31b protrudes from the lower edge of the lower bar 14a. We also see that the upper end of the uprights 31a 35 and 31b, is flush with the upper edge of the upper bar 14b. It can also be seen that the ends of the lower bars 14a and 14b exceed the uprights 31a and 31b. The stops 15a and 15b protrude laterally each relative to the amount on which they are fixed. The abutments 15 of the transverse walls are arranged at a determined height so as to come against and above the upper edge of one of the abutments 16 of the longitudinal walls. In Figure 4, there is shown the box 1 assembly. For this, the transverse walls 5 and 6 are positioned on the bottom 2 respectively along the transverse edges 11a and 11b. To this end, we do this in the following way. The transverse wall 5 is engaged by horizontal translation in the retaining means 13 corresponding to the transverse edge 11a by introducing the ends of the uprights 31a and 31b and the shims 30 fixed to these ends. In the final position, the wedges 30a and 30b and the lower ends of the uprights 31a and 31b are blocked by the retaining means 13 in the vertical direction. Thus, the transverse walls 5 and 6 are held rigidly on the bottom 2 preventing movement in the vertical direction. Note that there is provided here a retaining means 13 positioned in the vicinity of each end of the transverse wall 5 or 6 but could be provided a single retaining means of sufficient length to receive the wedges 30a and 30b of each transverse wall 5 or 6. Each transverse wall 5 or 6 is in this position locked in the vertical direction. In FIG. 4, it can also be seen that the lower end of one of the uprights of each transverse wall and one of their respective wedges 30a or 30b abut respectively against one of the two cleats 34a and 34d. Two of the cleats 34a and 34d, whatever their length, are fixed on the bottom 2 so as to form a stop for the transverse walls 5 and 6 during their installation. The other two cleats 34b and 34c are fixed on the bottom 2 at a distance from the retaining means 30 to leave free passage for the wedges 30a and 30b and the lower ends of the vertical uprights 31a and 31b during the horizontal translation of the transverse walls 5 and 6. After fixing one or more transverse walls 5 and 6 to the bottom 2, each longitudinal wall 3 or 4 is placed by interlocking or by horizontal translation, positioning its abutment 16a under the abutment 15b of the transverse wall and its abutment 16b under the abutment 15a of the other transverse wall, while the lower end of each of the uprights 25a and 25d outside bears against one of the cleats 34a, 34b, 34c or 34d. Furthermore each of these uprights 25a and 25d outside, that is to say those arranged along the lateral edges of the longitudinal wall 3, bears against the transverse walls 5 and 6. According to an example of mounting, a first wall lateral lateral 5 is mounted by a horizontal translation, that is to say a translation parallel to the bottom 2. Then a first longitudinal side wall 3 is mounted by a horizontal translation to abut against the wall 5 previously mounted. Then a second transverse lateral wall 6 is mounted by a horizontal translation to bear against the previously mounted wall 3. Finally, a second longitudinal lateral wall 4 is fitted against the cleats 34 and against the transverse lateral walls 5 and 6. This latter longitudinal wall 4 is fitted by positioning the lower ends of its uprights on the bottom 2, the wall 4 then being slightly inclined, then it is fitted by vertically straightening this wall 4. In final position, the longitudinal walls 3 and 4 are blocked outwards by the cleats 34 and towards the inside of the box 1 by the low horizontal bars 14a and high 14b transverse walls. We then see that the longitudinal walls 3 and 4 are free from the bottom 2, that is to say that they are not fixed directly to the bottom 2, and they are blocked by the other transverse walls 5 and 6. The longitudinal walls are also blocked by the cleats 34 fixed to the bottom. The assembly is completed by placing the upper corners 7- 10 by capping the ends of the upper uprights 25 and 31 disposed along the side edges of the side walls so as to further block the four walls 3-6 between them. These corners 7-10 complete the blocking of the four walls between them. This body 1 has two spacers 38a and 38b resting on the upper free ends of the uprights 25b and 25c intermediate the longitudinal walls 3 and 4. The withdrawal of the intermediate amounts is provided for this purpose. These two spacers 38a and 38b stiffen the structure of the body avoiding its flaring. Of course, this box is circled before delivery of the packaged material to ensure its good performance. It is easily understood that the box according to the invention can be delivered in the form of a kit at the customer's including the bottom 2 pre-equipped retaining means 13 and cleats 34, on which are arranged flat transverse side walls 3 and 4 and longitudinal 5 and 6, the two spacers 38 and the four corners 7. In Figure 5, there is shown a view of the retaining means 13 in the form of a U-shaped section 20 partially closed whose base 17 is extended by the wings 18a and 18b. Of course, this profile is fixed to the bottom 2 by means of screws with holes made in the base 17. The wing 18a is extended by a flap 19 disposed parallel to the base 17. The profile 13 defines then a semi-closed internal space 20 shaped to the dimensions of the shim 30a or 30b and the lower end of the uprights 31a or 31b, wherein a shim 30 is introduced to bear against the flap 19 to allow its locking. The side wall is thus locked in the retaining means. The clearance between each shim 30 and the low horizontal bar 14a is provided to facilitate the insertion of shims 30. The section 13 may be of any material, but a metal material is preferred.

In Figure 6, there is shown a cross section of the section 13 with its base 20, the flange 18a, the flap 19 and the internal space. This space is rectangular but it can be square, triangular or other. In the internal space 20, there is shown the disposition of the end of an upright 31 and its associated shim 30. The internal retaining space extends in one direction along a transverse edge, while the shim extends perpendicularly to this direction along a longitudinal edge. In Figures 7 and 8, there is shown one of the upper corners, here the corner 7 for example, the others being identical. Each upper corner 7 to 10 is in the form of a hollow part consisting of a lid 15 L plan 15, an outer arm 22 and an inner arm 21 extending the cover 36 and each forming portions arranged at right angle L-shaped. Two flaps 33 and 35 perpendicularly extend the inner arm 21 and are applied against the cover 36. These wedges thus secure the outer uprights 25a and 25d of the longitudinal walls and the uprights 31a and 31b. transverse lateral walls. The internal space 23 of each corner 7-10 is shaped like that of the corresponding upper part of each side wall 3 to 6. The folded portions 33 and 35 are in particular intended to come against the uprights of the longitudinal or transverse walls and to leave a free passage along the outer arm 22. This free passage allows the passage of the horizontal bars of the longitudinal or transverse walls.

Advantageously, the cover 36 and the flaps 33 and 35 of each upper corner 7 to 10 may be provided with a lug or two lugs 24 or more, allowing the limitation of displacement during the superposition of two boxes. Of course, these lugs 24 project upwards when the corners are put in place. The lugs protrude from the cover 36, opposite the arms 21 and 22. The corners 7-10 may be made of metallic material.
