Description

Combi box for transport and storage of goods

Technical area

The technical solution concerns a combi box for transporting and storing goods

Current state of the art

To transport different kinds of goods, various packages are used, crates or boxes in which the goods are deposited. The most well-known and used transport packaging is the “injected” boxes. These “injected” boxes are made in injection molds and are made of a single material. The disadvantage consists in the fairly high initial investment in injection tools, the rather high weight and the loss of housing volume with the increasing height of the body walls (chamfers required for demolding). The service life of the use of injected cases is limited. When the injection molded material has deteriorated and is no longer usable, the box is put out of use and crushed to recycle the plastic. Possibly, the injected box can be put out of use or become obsolete when the articles for which it is designed are no longer used. Other known means of transporting goods include "construction crates". These are made up of a base cut out of a flat material (using a cutting machine) and stacking profiles (manufactured using an extrusion mold). In comparison with the injected boxes intended for smaller articles, they are generally used to manufacture atypical dimensions. The disadvantage of "construction boxes" is the relatively high cost of mass production, often limited load capacity and more expensive recycling. Patent document EP 2369693 presents a box constructed from the cut injected box or, possibly, from the construction box. This cut box constitutes the lower part (the lower frame) and the upper part (upper frame) of the new box and an intermediate part is inserted between the

BE2018 / 5189 two cut parts, the latter is designated as an envelope. This intermediate part is assembled by welding with the lower part and the upper part coming from the cut injected box. The drawback of these welded boxes consists in the difficulty of positioning the lower part and the upper part of the cut body with respect to the intermediate part when it is necessary to fix their positions before the welding operation. The position is fixed using grooves formed on the intermediate part by depositing the ribs located on the cut parts of injected boxes. Even fixing the position using the ribs does not guarantee the correct positioning of the intermediate part to be welded to the lower part and to the upper part coming from the cut injected body. The two parts, lower and upper, must therefore be locked before welding mechanically which is quite disadvantageous. Another disadvantage of this box consists in the fact that when it is damaged, it is no longer usable.

Principle of the technical solution:

The drawbacks of the known means of transport and storage of goods are overcome thanks to the combi box conforming to the technical solution. The combi box is composed of a lower part and an upper part formed by cutting a worn or possibly new plastic, injected or construction box. Between the elements of the body thus cut, namely between the lower part and the upper part, an intermediate part is introduced (inserted). The latter forms an envelope comprising two open faces and its height may vary. The principle of the technical solution consists in that one of the open faces of the inserted part is assembled on its lower periphery with the lower part and on its upper periphery with the upper part by means of assembly by locking. The locking assembly contains a first locking element formed on the vertical rib of the lower part and on the rib of the upper part. The vertical ribs on which the first locking element is formed, are the original ribs located on the injected or construction cut box. This first locking element engages in the second locking element formed

BE2018 / 5189 on the lower perimeter and on the upper perimeter of the envelope of the inserted intermediate part.

The locking assembly is opened or closed depending on the embodiment of the second locking element. The surface of the closed locking assembly around the second locking element on the intermediate part is solid - compact. The open latch assembly is formed to create an opening conducted from the second latch to the open face of the intermediate portion. This opening makes it easier to assemble and slide the second locking elements into the first locking elements formed on the vertical ribs of the lower part and of the upper part because the wall of the intermediate part comprising the opening is more malleable. . The locking assembly consisting of a first locking element and a second locking element is called "simple locking assembly". In many cases, it is necessary to build a combi box whose dimensions are larger to support a greater weight of the goods transported. Thus it is necessary to double the assembly by locking. To create a double locking assembly, two first locking elements are formed on the vertical ribs of the lower part and of the upper part and two second locking elements are formed on the intermediate part. This type of locking assembly is referred to as double closed or double open. The surface around the second locking element of the double closed assembly located on the intermediate part is solid - compact. The double open locking assembly is formed so as to create an opening conducted from the second locking elements to the open face of the intermediate part and the two second locking elements are also connected by an opening. Triple or possibly multiple locking assemblies can also be created, but these embodiments no longer prove to be advantageous from a practical point of view. In certain cases of use of combi boxes, it will be necessary, particularly in the case of storage of goods, to leave at least one face of the assembled parts open, this will therefore form a space used to deposit or take the articles out of the box. It can be the short front side or the long side side or, optionally,

BE2018 / 5189 the combination of the two sides. Although the interlocking assemblies provide the assembled box parts with sufficient strength, the resistance of the assembled parts can be further reinforced by welding at several points or by mechanical assembly.

The advantage of this technical solution is the low cost of mass production, almost zero cost of extending a range of products, recycling of injected or worn construction cases, partially damaged or otherwise unusable, the low weight, the resistance required for the load can be obtained depending on the type of material used. In the majority of cases, the material of the different parts of the combi box is plastic, but the combination with other materials is not excluded. The combi box can be used to transport industrial goods, for example in the automotive, mechanical, electrical engineering, etc., as well as for the transport of food products, medicines, toys, etc.

Description of embodiments of the invention

The combi box 10 intended for the transport and storage of the goods illustrated by FIGS. 1 to 18 is made up of injected or construction boxes, worn or common. An injected or construction current case is cut in the middle to obtain a lower part 1 (above designated "lower frame" 1_) and an upper part 2 (above designated "upper frame 2). Between the lower frame 1_ and the upper frame 2 an intermediate part 3 will be inserted, it forms an envelope with two open faces, the height of this intermediate part 3 can vary and this depending on the goods transported or stored. The shape of this intermediate part 3 corresponds to the shape of the lower frame 1. and of the upper frame 2. This intermediate part 3 is assembled with the lower frame 1_ and the upper frame 2 by means of locking assemblies 4 at the faces. open. The locking assemblies 4 are formed on the surfaces of the lower periphery 3.1 and on the surfaces of the upper periphery 3.2 of the intermediate part 3 and on the vertical ribs 1.1 of the lower frame 1. and on the vertical ribs 2.1 of the upper frame 2. According to the different embodiments and according to the number of locking assemblies 4 formed between the intermediate part 3 assembled with the lower frame 1. and with the upper frame 2, the assembled parts can be used without other locking method or can be fixed to prevent their separation by welding or by a removable or non-removable mechanical assembly. In all the exemplary embodiments described below, provision is made to construct a combi box 10 comprising a lower frame 1_ and a lower frame 2 of construction adapted from an injected body or from construction and from an intermediate part 3 (intermediate casing) fixed to the frames by means of the locking assembly 4.

Figures 1 to 4 illustrate a combi box 10 of rectangular shape with four locking assemblies 4 formed on the opposite long sides of the assembled parts. The locking assemblies 4 are arranged so that the lower frame! is provided, on each long side on an original vertical rib 1.1 with a first locking element 4.1 comprising a recess 4.11 and

BE2018 / 5189 a projecting element 4.12 coming from the original vertical rib 1.1 of the cut body. The first locking elements 4.1 on the lower frame 1_ are relative to each other located diagonally (fig. 2 and 3). The upper frame 2 also comprises on each long side a first locking element 4.1 formed on an original vertical rib 2.1 and comprising a hollow 4.11 and a projecting element 4.12 coming from the original vertical rib 1.1 (fig. 2 and 4). On the lower periphery 3.1 and on the upper periphery 3.2 of the intermediate part 3, the second locking parts 4.2 are formed facing the first locking elements 4.1 and the latter form an orifice passing through a wall of the intermediate part 3. The shape of this orifice is designed so that the projecting elements 4.12 of the first locking element 4.1. commit to it. The second locking element 4.2 is surrounded by a solid wall of the intermediate part 3, this locking assembly 4 is therefore designated as a closed assembly. As the locking assembly 4 is formed by a first locking element 4.1 and a second locking element 4.2, this locking assembly 4 is designated as simple and closed. (NOTE: for example figs. 13 and 14 show an assembly with double closed locking, see description of these figures below). To ensure greater stability of the assembled parts, the lower frame 1. and the upper frame 2 of the cut box are provided with structural adaptations and the vertical ribs 9 are kept to be inserted in the grooves 11 formed on the lower periphery 3.1 and the upper periphery 3.2 of the intermediate part 3. Two grooves 11 are formed on the short sides of the assembled parts and a groove 11 is formed on the long sides. To assemble the intermediate part 3 with lower frame 1. and with the upper frame 2, it is proceeded so as to install the intermediate part 3 on the lower frame 1_ and on the upper frame 2 until the first locking element 4.1 fits into the second locking element 4.2 which creates a locking assembly 4. The assembly of the intermediate part 3 with the lower frame 1. and the upper frame 2 using four locking assemblies 4 ensures a sufficiently precise position of the assembled parts for their possible subsequent fixing by means of a mechanical assembly, for example by means of welds at points 12 or at

BE2018 / 5189 using removable or non-removable assemblies at points 13 on the short sides of the combi box 10.

Figures 5 and 6 show a combi box 10 of rectangular shape where each side of the intermediate part 3 is assembled, on the lower periphery 3.1 and on the upper periphery 3.2, with the lower frame 1_ and the upper frame 2 by means of two locking assemblies 4, in total the lower frame 1_ is fixed to the edges of the sides 3.1 of the intermediate part 3 by means of eight locking assemblies 4 and the fixing of the edges of the sides 3.2 of the intermediate part 3 to the upper frame 2 includes the same number of assemblies per lock

4. The method for producing the locking assemblies 4 is designed in the same way as in the case of the examples in FIGS. 1 and 2, namely a first locking element 4.1, formed on the vertical ribs 1.1 of the lower frame 1. and on the vertical ribs 2.1 of the upper frame 2, is inserted into the second locking element 4.2 formed on the intermediate part 3. This number of assemblies by locking ensures a sufficiently solid fixing between the frames 1 and 2 fixed to the intermediate part 3, it is therefore no longer necessary to carry out other means of fixing the assembled parts. In this exemplary embodiment, the assembly by locking 4 is also carried out as simple and closed, therefore the second locking element 4.2 on the intermediate part 3 is surrounded by a solid surface. However, this variant of attachment by means of 16 locking assemblies does not exclude additional attachment, for example by means of welds.

FIGS. 7 to 16 show the different alternative embodiments of the locking assembly 4.

FIGS. 7 and 8 illustrate the production of the simple open locking assembly 4. This simple and open locking assembly 4 is formed so as to make an opening 6 driven from the second locking element 4.2 on the lower periphery 3.1 and on the upper periphery 3.2 of the intermediate part 3 towards the open faces of the intermediate part 3. The first locking element 4.1 on the upper frame 1_ and on the lower frame 2 is

BE2018 / 5189 formed identically to that of the previous embodiments. This opening 6 facilitates the insertion of the second locking elements 4.2 into the first locking elements 4.1 formed on the vertical ribs 1.1 of the lower frame 1. and on the vertical ribs 2.1 of the upper frame 2.

Figures 9 and 10 illustrate an embodiment of the assembly by simple closed locking 4 formed on the vertical rib 2.1 for fixing the upper frame 2 to the intermediate part 3, the recess 4.11 of the first locking element 4.1 being formed on the long part of the vertical rib 2.1 and the projecting element 4.12 being formed on the short part of the vertical rib 2.1. The second locking element 4.2 formed on the upper periphery 3.1 of the intermediate part 3 is produced more deeply in the wall of the intermediate part 3 (fig. 9). To fix the lower frame 1_ to the intermediate part 3, the locking assembly 4 is formed on the vertical rib 1.1 of the lower frame 1_, the recess 4.11 being produced in the long part of the vertical rib

1.1 and the protruding element 4.12 on the short part of the vertical rib 1.1. The second locking element 4.2 formed on the lower periphery 3.1 of the intermediate part 3 is produced more deeply in the wall of the intermediate part 3 (fig. 10).

Figures 11 and 12 illustrate the production of the simple locking assembly 4 of identical design to that described for the examples in Figures 9 and 10. The difference of this locking assembly consists in the fact that from the second element 4.2 for locking an opening 6 leading to the open faces of the intermediate part 3 is made to facilitate the insertion of the second locking element 4.2 into the first locking element 4.1 on the lower frame 1_ and on the upper frame 2.

Figures 13 and 14 illustrate the embodiment of the assembly by double closed locking 4 fixing the intermediate part 3 to the lower frame 1. and to the upper frame 2. The design of the assembly by double closed locking contains the same elements as the design described in the previous examples but on the vertical rib 1.1 of the lower frame 1_ and on the rib

BE2018 / 5189

2.1 of the upper frame 2 two first locking elements 41 are formed comprising the hollow 4.11 and the projecting element 4.12. On the lower periphery 3.1 and the upper periphery 3.2 of the intermediate part 3, two superimposed second locking elements 4.2 are formed in which the first two locking elements 4.1 are inserted. When the rectangular combi box comprises two assemblies by double locking on each side located on the two lower vertical ribs 1.1 and on the two upper vertical ribs 2.1, the total number of assemblies by locking on the periphery of the combi box is 32. This embodiment of the locking assembly is suitable above all for large combi boxes with a higher permissible load.

Figures 15 and 16 illustrate the embodiment of the assembly by double open locking 4 which fixes the intermediate part 3 to the lower frame 1. and to the upper frame 2.1. It is a design of the locking assembly identical to that described for the exemplary embodiments of FIGS. 13 and 14. The difference of this locking assembly 4_consists in the fact that from the second locking element 4.2 an opening 6 leading to the open face of the intermediate part 3 is made and an opening 7 is also made between the two second overlapping locking elements 4.2. These openings 6 and 7 facilitate the insertion of the second locking elements 4.2 into the first locking elements 4.1 on the lower frame 1_ and on the upper frame 2.

Obr. 15 a 16 znâzornuji provedeni dvojnâsobného otevreného zâmkového spoje 4, kterÿ spojuje stredni cast 3 se spodnim râmem 1_a s hornim râmem 2.1.

Figures 17 and 18 illustrate a combi box 10 of rectangular shape composed of the intermediate part 3 and the lower frame 1. and the upper frame 2, the intermediate part 3 being assembled with the lower frame 1. and the upper frame 2 by means assembly by simple and open locking 4. The design of the assembly by simple and open locking is identical to the example of the embodiment described and illustrated by FIGS. 7 and 9. But a short side of the assembled parts 1, 2 and 3 is an open face 8. This solution is suitable above all

BE2018 / 5189 to store the goods on the shelves or the open face 8 presents a solution for accessing the stored goods. The open face 8 can also be formed on the two opposite short sides or on the adjacent short and long sides. To reinforce the resistance of the assembled elements 1_, 2 and 3, these 5 are further assembled by welding at points 12.

Although several variants of the assembly of the lower frame 1_ and of the upper frame 2 with the intermediate part 3 of the combi box have been described and illustrated, no other combination is excluded, for example, the lower frame 10 of a box combi will be assembled with the intermediate part by a double assembly by closed locking and the upper frame by a simple and open locking assembly, etc. An additional reinforcement of the resistance of the assembled parts by welding or by mechanical assembly is not excluded either.
