EP4470725B1 - Modular storage assembly - Google Patents

Description

The present invention relates to a storage assembly composed of several elements which are of modular type and are combinable with each other, so as to make said assembly adjustable according to the specific needs of the user.

We know of such sets which are used in different types of industry to store objects permanently or temporarily.

Such sets are used in the entertainment sector, and particularly in the cinema sector where, for the purposes of filming a film, the staff need to store and make available to the various users a wide variety of items, ranging for example from the actual filming equipment to the "rollers" intended to contain and present to the filming staff the supplies they need.

We thus know of storage units, often arranged on trolleys, which are made up of lockers whose number and dimensions, which are fixed for a given unit, depend on the use that is to be made of them.

Such storage units usually consist of a supporting base supporting horizontal and vertical metal uprights which are welded together to form a specific number of racks in the very specific dimensions required.

We know this by the patent EP 0640447 a device for storing and displaying tools, which comprises several stacked racks which are housed and held within a rigid structure.

It is understood in these conditions that each storage set is defined by several essential parameters, namely on the one hand the number of lockers and on the other hand the dimensions of each of these, namely their width, and their height and possibly their depth, without forgetting their relative arrangement. A user who has the need for a given application of a storage set comprising a well-defined number of lockers whose dimensions are also well-defined will often have difficulty in finding in an existing stock the set of ideal storage, especially since its requirements can also extend to the arrangement of these lockers in relation to each other.

This user will therefore have no other option than to have the storage unit he needs specially manufactured, which is costly both in terms of time and budget.

We also know by the patent application FR 21.04680 a modular storage unit which has the advantage of being able to be put together on demand, from a few basic elements, in a particularly easy and rapid manner, this storage unit being able, in particular, after use, to be easily transformed to create a new, different configuration.

This storage assembly thus comprises at least one module supported by a carrier base, this module being made from at least one folded sheet, in particular a metal sheet, so as to form a rectangular flat frame, each of the longitudinal and transverse sides of which comprises an internal fold forming a first wing perpendicular to the plane of the frame and extending downwards which is itself folded at 90° inwards to form a second wing parallel to the plane of the frame, said second wings being arranged in the same plane.

It should be noted, however, that such a storage unit is formed from constituent parts, some of which have a large deployed volume, which constitutes a disadvantage on the one hand with regard to its ease of storage and shipping and on the other hand with regard to the quantity of material used for its manufacture.

The patent application US 4 183488 A discloses the preamble of claim 1.

Such storage sets are also known from documents US 2015/157144 A1 And US 4 261470 A .

The object of the present invention is to propose a modular type storage unit which can be assembled on demand, from a few basic elements, in a particularly easy and rapid manner, this storage unit being able in particular, after use, to be easily transformed to create a new different configuration and which, moreover, is formed of constituent elements which are presented prior to assembly in a particularly compact form thus lending itself easily to its storage and transport. In addition, the present invention makes it possible to achieve particularly substantial savings on the quantities and therefore on the cost of the materials used for its manufacture.

• chaque extrémité de la première aile se terminant par une patte de fixation dite primaire, et chaque extrémité de la seconde aile se terminant par une patte de fixation dite secondaire, lesdites pattes de fixation s'étendant vers l'intérieur de l'élément cornière,
• l'écartement existant entre la patte de fixation primaire et la patte de fixation secondaire, à chacune des extrémités d'un montant, étant égal à l'épaisseur de l'embase augmentée d'une fois l'épaisseur des pattes de fixation.

The present invention thus relates to a storage assembly of the type comprising at least one series of at least one module, each module comprising a base and perpendicular uprights connected to it, each upright being made up of an angle element formed of two perpendicular wings, namely a first wing and a second wing,

• each end of the first wing ending in a so-called primary fixing lug, and each end of the second wing ending in a so-called secondary fixing lug, said fixing lugs extending towards the inside of the corner element,
• the gap existing between the primary fixing lug and the secondary fixing lug, at each end of an upright, being equal to the thickness of the base increased by one time the thickness of the fixing lugs.

In one embodiment of the invention, the second wing will be longer than the first wing, and in another embodiment, both wings may be the same length.

The amounts of the same module can advantageously be of identical shape and dimensions.

• la première aile d'un montant et la seconde aile de l'autre montant seront coplanaires,
• une patte de fixation primaire d'un premier montant sera appliquée contre une patte de fixation secondaire de l'autre montant et une patte de fixation secondaire du premier montant sera appliquée contre une patte de fixation primaire de l'autre montant.

The storage unit may comprise at least one series of at least two superimposed modules comprising at least four pairs of adjacent aligned uprights in which, for each pair of said uprights:

• the first wing of one upright and the second wing of the other upright will be coplanar,
• a primary fixing lug of a first upright will be applied against a secondary fixing lug of the other upright and a secondary fixing lug of the first upright will be applied against a primary fixing lug of the other upright.

• les premières ailes de chacun des montants adjacents alignés seront coplanaires, et les secondes ailes de ces montants seront également coplanaires,
• une patte de fixation primaire d'un premier montant sera appliquée contre une patte de fixation primaire de l'autre montant, et une patte de fixation secondaire du premier montant sera appliquée contre une patte de fixation secondaire de l'autre montant.

In an alternative embodiment of the invention, the storage assembly may comprise at least one series of at least two superimposed modules comprising at least four pairs of aligned adjacent uprights, in which for each pair of said uprights:

• the first wings of each of the adjacent aligned uprights will be coplanar, and the second wings of these uprights will also be coplanar,
• a primary fixing lug of a first upright will be applied against a primary fixing lug of the other upright, and a secondary fixing lug of the first upright will be applied against a secondary fixing lug of the other upright.

The uprights and/or the base may be made of metal, in particular stainless steel, and the primary fixing lugs and the secondary fixing lugs may be obtained by bending.

According to the invention, the uprights and/or the base may also be made of a synthetic material and then be produced in particular by molding.

The base may form a rectangular flat frame, each of the transverse and longitudinal sides of which may comprise, on the one hand, two transverse internal flanks and two longitudinal internal flanks perpendicular to the plane of the frame and, on the other hand, two transverse external flanks and two longitudinal external flanks perpendicular to the plane of the frame, the transverse internal flanks and the longitudinal internal flanks extending downwards and extending at 90° towards the interior of the frame to form respectively transverse internal wings and longitudinal internal wings which will be parallel to the plane of the frame, said internal wings being furthermore coplanar.

The transverse external flanks and the longitudinal external flanks of the base may extend at 90° towards the inside of the frame, to form respectively transverse external wings and longitudinal external wings coplanar and parallel to the transverse sides and the longitudinal sides.

The transverse flanks may extend over the entire width of the base and the ends of the transverse external wings and the longitudinal external wings may extend up to a distance from the ends of the frame equal to the width of the wings of the uprights.

Furthermore, the ends of the longitudinal sides may extend up to a distance from the longitudinal ends of the frame, this distance being less than the width of the wings of the uprights.

The storage unit may include at least two series of at least one module, the lower bases of which will be connected by at least one stiffening bar.

This stiffening bar may be placed in the space between the transverse side of the base, a transverse external flank of the base, and one end of a longitudinal external flank of the base.

The storage unit may comprise at least two series of at least one module, and the overall height of these at least two series of at least one module may be the same and their upper part may be closed by a tray common to said two series.

According to the invention, at least two adjacent uprights belonging to each of the aforementioned at least two series may be secured by removable fixing means.

Furthermore, at least two of the bases belonging to each of the aforementioned at least two series may be secured by removable fixing means.

The storage unit may comprise two wheels which will be secured to a lower base by means of a gusset on which they will be fixed, said gusset being made up of a metal plate, two adjacent sides of which will be folded at 90° so as to form a flank perpendicular to the plate, this flank itself being folded at 90° towards the inside of the plate so as to form two wings parallel to the latter, the distance between said plate and said wings being equal to the thickness of the base.

Finally, in order to save on the material used when the base and the uprights are made from a metal sheet, in particular a stainless steel sheet, the length of the uprights may be less than the distance separating the two internal transverse wings of the base, thus making it possible to make them in a metal part intended for waste.

It has been represented on the figure 1 a perspective view of an example of a storage assembly 1 according to the invention.

This storage assembly 1 is made up of three series of modules 2, each series comprising at least two modules stacked on top of each other. These series are arranged side by side, namely a first series A of two modules 2, a second series B of three modules 2 and a third series C of four modules 2. It would of course be possible, according to the invention, to combine in the same way any number of series, each made up of any number of modules 2, and this depending on the use that is intended to be made of the storage assembly 1.

It is thus understood that each module 2 is made up of a base 3 and four vertical uprights 5, the upper module being closed by a cover 7 which can be made up, as shown in the figure 1 , by a receiving plane covering several series of modules or in particular by a base 3 as shown on the figure 13 .

The amounts 5 which are represented in detail on the figure 2 are, for a given module 2, all identical and are made from a metal angle element, in particular stainless steel, that is to say an element which is formed of two wings 6a and 6b which are perpendicular and have a width m. The first wing 6a, which we will designate hereinafter in this text as "primary wing", is folded at each of its ends at 90° towards the inside of the angle, so as to form a fixing lug called "primary lug" 8a.

Likewise, the second wing 6b, which we will refer to hereinafter in this text as “secondary wing”, is folded at each of its ends at 90° towards the inside of the angle iron, so as to form a fixing lug called “secondary lug” 8b.

The secondary wings 6b are of greater length than the primary wings 6a, so that once the legs 8a and 8b are formed, they are located at a distance E from each other at each end of the upright, as shown in the figures 2 to 3 .

It has been represented on the figure 2 two uprights before their installation, namely an upper upright 5a and a lower upright 5b, this installation being carried out by a simple relative movement of the uprights in the direction of arrow F.

When the two upper 5a and lower 5b uprights are correctly positioned, as shown in the figures 3 And 4 , it is noted on the one hand that the primary wing 6a of the upper upright 5a and the secondary wing 6b of the lower upright 5b are coplanar, as are the secondary wing 6b of the upper upright 5a and the primary wing 6a of the lower upright 5b. It is also noted that a secondary leg 8b of the lower upright 5b comes into contact with a primary leg 8a of the upper upright 5a and, under these conditions since the uprights 5a and 5b are identical, a primary leg 8a of the lower upright 5b comes into contact with a secondary leg 8b of the upper upright 5a.

It is understood that once the two amounts 5a and 5b are in position, as shown in the figure 3 , the gap E' existing between the lower face of the secondary leg 8b of the lower upright 5b and the upper face of the secondary leg 8b of the upper upright 5a is as follows: $$\mathrm{E}\text{'}=\mathrm{E}-\mathrm{e}$$

This space E' is intended to receive a base 3 of thickness a=E' , as shown in the figures 5 to 10 . The installation is carried out by a simple relative displacement of the pair of uprights 5a/5b in the direction of the arrow F1 as shown in the Figure 5 .

In order to ensure the attachment of the two uprights 5a and 5b to the base 3, the latter and the legs 8a and 8b of the uprights are provided with holes 10, 10a which will be crossed for example by tightening bolts, not shown in the drawing. Other means of fixing could of course be used as explained below.

In an implementation variant shown in the Figure 2a , to produce the amounts differently, while remaining within the scope of the present invention.

Thus, these upper 5'a and lower 5'b uprights are also made from an angle element therefore having two perpendicular wings, namely a primary wing 6'a and a secondary wing 6'b, these uprights being identical in shape and dimensions for the same module 2. The primary wing 6'a ends at each of its ends with a fixing lug called primary 8'a and the secondary wing 6'b ends at each of its ends with a fixing lug called secondary 8'b. Unlike the previous embodiment, the two primary 6'a and secondary 6'b wings are of the same length. Furthermore, at each end of an upright, the two primary and secondary legs are spaced apart by a distance E , the latter being equal, as in the previous embodiment, to the thickness a of a base increased by the thickness e of the legs 8'a and 8'b.

• d'une part, les ailes primaires 6'a des montants supérieur 5'a et inférieur 5'b soient coplanaires et que les ailes secondaires 6'b des montants supérieur 5'a et inférieur 5'b soient également coplanaires,
• de seconde part, les pattes 8'b des montants supérieur 5'a et inférieur 5'b soient en contact ainsi que les pattes 8'a des montants 5'a supérieur et inférieur 5'b.

As shown on the Figure 2a , these legs are positioned in such a way that:

• on the one hand, the primary wings 6'a of the upper 5'a and lower 5'b uprights are coplanar and that the secondary wings 6'b of the upper 5'a and lower 5'b uprights are also coplanar,
• secondly, the legs 8'b of the upper 5'a and lower 5'b uprights are in contact as well as the legs 8'a of the upper 5'a and lower 5'b uprights.

The bases 3 can be made up of simple solid panels made of any rigid material such as wood or PVC (polyvinyl chloride), as shown in the figures 5 And 6 . More interestingly, these bases 3 can be made of a shaped metal sheet, in particular folded stainless steel, or a rigid composite material for example as shown in the figures 7 and following.

In this latter embodiment, the base 3 forms a rectangular frame having transverse sides 12 and longitudinal sides 14 as specified below, each of these sides comprising an external flank and an internal flank which is perpendicular to them. Thus, the longitudinal sides 14 comprise an external flank 14a and an internal flank 14b and the transverse sides 12 comprise an external flank 12a and an internal flank 12b. The external transverse flanks 12a extend over the entire width of the side 12, unlike the longitudinal flanks 14a which stop at a distance g from each end, as shown in the figures 7 and 8 , this distance g being less than the width m of the uprights 5a and 5b.

The transverse external flanks 12a and the longitudinal external flanks 14a are folded at 90° towards the inside of the base, so as to form respectively transverse 12c and longitudinal 14c wings which are parallel to the sides 12 and 14, as shown in the figure 8 . Furthermore, it will be noted that these transverse 12c and longitudinal 14c wings stop at a distance f from the respective ends of the transverse 12 and longitudinal 14 sides, this distance f being equal to the width m of the uprights 5a and 5b.

Likewise, the transverse internal flanks 12b and the longitudinal internal flanks 14b are folded at 90° towards the inside of the base, so as to form respectively transverse internal wings 12d and longitudinal internal wings 14d coplanar and parallel to the sides 12 and 14. This defines a recessed supporting plane which can securely receive the base of a product storage bin, and preferably a standard format bin called "Europe". This supporting plane, insofar as it is recessed between the flanks 12b and 14b, ensures the holding of the bins and prevents them from slipping.

It should be noted that these different folds cooperate to ensure two functions, namely on the one hand to constitute the aforementioned embedded supporting plane and on the other hand to create stiffening ribs which give the module its own rigidity, both in the transverse and longitudinal direction.

Of course, according to the invention, the base 3 could also be made of a synthetic material, obtained in particular by molding.

The installation of a pair of uprights, that is to say an upper upright 5a and a lower upright 5b assembled, is carried out as previously in the example of a solid base, as shown in the figures 9 And 10 . Such an assembly is then slid into a corner of the base 3 in the direction of the arrow F3 as shown in the figure 9 .

In this arrangement, and as shown on the figure 10 , the secondary leg 8b of the lower upright 5b comes into contact on the one hand with the upper face 12 of the base 3 and on the other hand with the leg 8a of the upper upright 5a, and the lower leg 8b of the upper upright 5a comes into contact on the one hand with the part 12e of the transverse external flank 12a which is included between the end of this flank and the end folded 12c of the transverse wing 12a and on the other hand with the tab 8a of the lower upright 5b.

As mentioned previously, the fixing can be ensured by any tightening means applying the fixing lugs to the base, and in particular by bolts 13 which pass through the holes 10 of the fixing lugs and the hole 10a of the base 3.

Depending on requirements, a series of A modules can be created by superimposing them on top of each other as shown in the figure. figure 13 , just as several of these series of modules A, B, C can be assembled together as shown in the figure 1 .

The series of modules A, B, C can be held together by screwing or, preferably, by fixing devices that are quickly and easily implemented, without the need for tools. Staples can thus be used, for example of the type shown in the figures 14 to 16 . Such a clip 18 can thus be made up of a rectangular plate 18a comprising at each end a bolt 18b intended to be placed in an oblong window 19 made in two adjacent uprights 5 which it is desired to connect. The dimensions of these bolts are such that once they are placed in the two adjacent windows 19, the plate 18a is strongly applied with a force F4 against each upright 5, thus ensuring a good lateral connection of the latter.

It is also possible to use means for connecting two adjacent bases whose upper surface is at the same level, in particular by means of the staples 18 mentioned above.

Furthermore, in order to promote overall stiffening of several series of modules A, B, C, it is possible, as shown in the figure 17 , use stiffening bars 20 which will connect the lower bases of these different sets of modules together.

Indeed, as represented on the figure 17 , it is understood that the lower bases 3 do not receive lower uprights 5b, so that, taking into account the fact that the longitudinal flank 14a does not extend over the entire length of the longitudinal side 14, an opening is thus created, and this opening allows the introduction of a stiffening bar 20 which will cross the adjacent lower bases of the different series of modules A, B, C, ... etc. and thus ensure their rigidity. As well as represented on the figure 18 , it is thus possible to arrange two stiffening bars 20 ensuring the rigidity of said series of modules.

The storage unit according to the invention may preferably include wheels 24 allowing it to be moved easily, which makes it possible to constitute, as shown in the figures 1 , 19 And 22 mobile equipment usually referred to as “rolling”.

The wheels 24 may in particular be held by support gussets 22 which are essentially constituted, in the present embodiment, by a square of folded metal sheet, in particular stainless steel. Such a gusset 22, as shown in the figure 20 , comprises on two of its adjacent sides a double fold, namely a first fold at 90° forming a flank 22a perpendicular to the plate, followed by a second fold at 90° in the direction of the latter and forming a wing 22b parallel to said plate, the spacing b between the plate and the wings 22b being equal to the thickness a of the base 3, so as to ensure its maintenance when the gussets 22 are arranged on it, as shown in the figure 21 , the fixing being able to be ensured by bolts or rivets. The wheels 24 are rotatably mounted on supports 26 which are secured to the gussets 22.

The wheels 24 can be arranged under the base 3, as shown in the figure 19 , or be arranged on either side of it, as shown on the figure 22 .

The storage assembly according to the present invention is particularly interesting in that firstly its assembly and disassembly are particularly easy and quick, since they can be carried out without the need to use tools.

Furthermore, it is understood that to produce modules of different heights, it is simply sufficient to use uprights of different lengths, uprights which, for a module of given height, are all identical. Under these conditions, a user who has bases and several series of uprights of different heights is able to easily and quickly produce a storage unit whose different series of modules A, B, C etc. have different heights, and this according to the needs, as shown in the figure 1 . In fact, the latter includes a first series A formed from a first stack of two high-rise modules, a second series B formed of a second stack of three medium-rise modules and a third series C formed of a stack of four low-rise modules.

Another advantage of the present invention lies in the fact that a user, provided that he has a few uprights of different heights, will be able to quickly and easily modify the composition of his existing storage unit, according to specific needs, without having to call on external contractors to do so, which represents a saving of time and substantial savings for him.

Such a storage unit is thus particularly interesting in the rental sector, where user customers have specific and varied needs. In such a sector, the present invention allows, for example, a rental company, once the service has been completed, to partially dismantle the recovered storage unit in order to transform it to meet the wishes of a new customer, or to replace a particular module that may have been damaged during the service.

It would also be possible for the lessor to completely dismantle the recovered storage unit in order to have the uprights and bases in reserve, which would then become available for another service, which is particularly easy due to the reduced volume of the constituent elements of the storage unit.

Another advantage of the present invention relates to the storage and shipping of such storage units, insofar as their individual parts, since they are essentially made up of uprights and bases, are presented in a particularly compact form, particularly in comparison with the storage units of the prior art, particularly when they are made of mechanically welded construction.

Finally, the present invention is particularly interesting with regard to the saving of raw material used, which in the case where the latter is made of stainless steel can prove to be particularly significant.

In particular, during the turning/stamping operation involved in the manufacture of the bases 3, the metal plate included inside the frame 12-14 between the wings 12d and 14d which usually constitutes waste can be used to make the uprights 5a, 5b, when the length of the latter is less than the existing dimension between the wings 12d.
