MODULAR ASSEMBLY SYSTEM COMPRISING PART AND RESPECTIVE REMOVABLE CONNECTION ELEMENT

Technical Field

The present invention relates to a part for modular fitting with the respective removable connection element suitable for fitting into said part and to the respective modular assembly system, used in the assembly of shelves and other similar structures, having as a main use the organisation area of interior spaces in domestic, office or industrial use, or in outdoor spaces.

Background of the Invention

The organisation of spaces has become increasingly important in everyday life, especially when spaces are insufficient for storing objects.

There are separate modules to attach to walls, hang behind doors to put shoes on, etc. There are shelves that are neither adjustable nor adaptable to the spaces to be organised. There are shelves adjustable to the width through internal springs that fix to the walls by means of pressure or by means of support pins.

So far there is no product that creates organisation for custom spaces. Known products are fixed or adjustable to the width, forcing them to limit themselves to the measures of the part, still leaving unused spaces both in terms of width and height.

The possibility of building a shelf of the required size and format, without using tools or without resorting to specialist workshops for cutting and assembling shelves is not known. There is no possibility of easily dismantling in seconds and re-assembling the shelf in a more suitable format for the place, if there is a need for adjustment due to natural evolution or simply because of the desire to reformulate the spaces, using the same parts and reusing all the material acquired before.

There are no products that allow the purchase of some additional parts that are fully compatible with the parts of the original product to add storage spaces, without wasting the previous material.

The existing possibilities are all better suited to remain inside cupboards, wardrobes, shoe racks, etc., as they do not have appealing aesthetics to be seen on the outside of the furniture. In addition, most existing space organiser possibilities come with assembly instructions that are not always easy to interpret and assembly tools, screws and other accessories which lead to unnecessary expenses and waste of tool parts.

Patent application US4232916A discloses a demountable and stackable container that uses a pair of panels, with several slots to slidably engage into other panels in various combinations, allowing it to be assembled and disassembled without the use of tools. This container serves various purposes, e g., document storage, etc. This container differs from the present invention because it is very restricted in terms of arrangement possibilities for modules according to the user’s needs, it is composed of many different parts and has as disadvantages the fact that each module is limited to a certain arrangement because the parts that make up a module are different from the parts of another module; it leads to the waste of parts because the modules are not versatile and, if a certain arrangement does not serve the user, the parts of that module are unusable; it requires a lot of instructions, because each module is assembled differently and has several different parts and several different fitting systems.

Patent US10555605 B1 describes a system for creating a modular shelving or storage unit, with different parts configured to be slidably joined without the use of any adhesive and being able to form a box. A plurality of boxes may be slidably joined to form a plurality of joined boxes. This custom modular shelving system can be constructed in a simple way, fitting into almost any area of physical space. This system has the disadvantage of having many different parts to assemble a single space, compared to the present invention which has two types of parts; being that the existence of several different parts demands several ways of fitting; and the useful spaces will always have to be limited to the square shape and with waste of useful space, because some squares are smaller than the others, and in the larger ones there must remain empty spaces due to the fittings that protrude from the plates.

Patent application EP2853172A1 discloses a furniture system comprising a plurality of basic building blocks. These blocks serve as storage space and as a division between work areas. The blocks form cells that are adapted to be combined and arranged to provide a variety of furniture system arrangements. This system has the disadvantages of requiring more than one part model, and many fitting elements; limiting the useful space to the size of the square and not allowing a partition to be created at half height to place wider and shorter objects, such as shoes, wasting half the space because if a pair of shoes is placed in a square, the shoes only occupy the lower half of the square.

In view of the above, there is a need to develop a part for modular fitting that results in a modular assembly system adapted to the needs of users, that is easy to assemble and disassemble through the use of the same parts, that does not require tools and that reuses all the material acquired before, that avoids the creation of wasted spaces and with which it is possible to build different configurations according to what is desired.

The objective of the present invention is to develop a part for modular fitting with the respective removable connection element suitable for fitting to said part and to the respective modular assembly system that overcomes the mentioned disadvantages with reference to the state of the art. Summary of the Invention

The present invention relates to a part (1 ) comprising a plurality of cavities (100, 101 , 102, 103, 108, 109, 115, 116) embedded in said part (1 ) and a fixed connection element (104) integrated in a third face (106) of the part (1 ) for modular fitting into at least another part (1 ), by means of at least one removable connection element (2), wherein each cavity (100, 101 , 102, 103, 108, 109, 115, 116) of the part (1 ) has a shape such that corresponding to the shape of the fixed connection element (104) and to the shape of the removable connection element (2).

The present invention also relates to the respective modular assembly system obtained through the fitting of at least two parts (1 ) by means of at least one removable connection element (2).

Detailed Description of the Invention

The present invention relates to a part (1 ) comprising a plurality of cavities (100, 101 , 102, 103, 108, 109, 115, 116) embedded in said part (1 ) and a fixed connection element (104) integrated in a third face (106) of the part (1 ) for modular fitting into at least another part (1 ), with at least one removable connection element (2), wherein each cavity (100, 101 , 102, 103, 108, 109, 115, 116) of the part (1 ) has a shape such that corresponding to the shape of the fixed connection element (104) and to the shape of the removable connection element (2). The present invention also relates to the respective modular assembly system obtained by fitting of at least two parts (1 ) with at least one removable connection element (2). The part (1 ) is symmetrical in two planes. The first plane is halfway between a fourth face (107) and a fifth face (110). The second plane is halfway between a first face (105) and a second face (114). The part (1 ) has the shape of a rectangle and comprises a first face (105) opposite a second face (114), a fourth face (107) and a fifth face (110) longitudinal and opposite to each other, a sixth face (111 ) and a third face (106) opposite to each other, wherein the third face (106) has a fixed connection element (104) integrated.

The fixed connection element (104) projects out of the third face (106) creating an overhang with half the depth of a removable connection element (2) in order to fit into any cavity (100, 101 , 102, 103, 108, 109, 115, 116) and becoming totally invisible. The cavities (100, 101 , 102, 103, 108, 109, 115, 116) of the part (1 ) have the same depth as the fixed connection element (104) in order to fit into the fixed connection element (104) in its entirety. Each cavity (100, 101 , 102, 103, 108, 109, 115, 116) has a shape corresponding to the removable connection element (2) and the fixed connection element (104).

The fixed connection element (104) is an integral part of the part (1 ) and is produced in the same production mould as the part (1 ), forming a single body with the part (1 ), without any type of connection between it and the part (1 ), therefore not being glued nor having any other type of connection. The fixed connection element (104) has a notch (113) of the concave surface that allows the total and complete fitting of two parts (1 ) in a durable and stable way in any cavity of the part (1 ). The fixed connection element (104) has the function of guaranteeing the fit in any cavity of the part (1 ). Likewise, the removable connection element (2) has the function of guaranteeing the fit in any cavity of the part (1 ).

The third side face (106) is arranged perpendicularly to the first face (105), to the second face (114), to a fourth face (107) and to a fifth face (110); the fourth face (107) is arranged perpendicularly to the first face (105), to the third face (106) and to a sixth face (111 ); the fifth face (110) is arranged perpendicularly to the first face (105), to the third face (106) and to the sixth face (111 ); said sixth face (111 ) is arranged perpendicularly to the first face (105), to the fifth face (110) and to the fourth face (107); a second face (114) opposite the first face (105).

The rectangular first face (105) has a first cavity (100) embedded in a first end of the first face (105), close to the fixed connection element (104), and arranged perpendicularly to said first face (105) and a second cavity (101 ) embedded in a second end, away from the fixed connection element (104), opposite to said end of the first face (105), and also arranged perpendicularly to said first face (105).

The third side face (106) has an integrated fixed connection element (104) that projects perpendicularly towards the outside of said third face (106). Said third face (106) cannot be seated on a surface, as the fixed connection element (104) integrated in this face unbalances its seating on that surface, leading to imbalance and subsequent fall of the part (1 ) and, subsequently, of the modular system.

The fourth side face (107) has a first cavity (102) embedded and located near the end closest to the third face (106) and a second cavity (103), also embedded closer to the sixth face (111 ).

The fifth side face (110) has a first cavity (108) embedded and located near its end closest to the third face (106) and a second cavity (109), embedded closer to the sixth face (111 ).

The sixth side face (111 ) is a flat face, devoid of cavities or fixed connection elements (4), allowing that when shelves are mounted with this sixth face (111 ) facing forwards, being visible to the user, they present a more attractive aspect, where the user only sees smooth faces. Another reason for said sixth face (111 ) being devoid of cavities is to ensure adequate spacing between two or more cavities from other parts (1 ) when these are mounted coupled together. As will be easily understood, the only face of the part (1 ) that should not be resting on a surface is the third face (106).

The rectangular second face (114) is opposite to the first face (105) and has a first cavity (115) embedded in a first end of the second face (114), close to the fixed connection element (104) and a second cavity (116) embedded into a second end of the second face (11 ), away from the fixed connection element (104) and opposite to said first end of the second face (114).

The fixed connection element (104) has an elongated shape and is suitable for fitting into any cavity (100, 101 , 102, 103, 108, 109, 115, 116) embedded in the faces (105, 107, 110, 114) of the part (1 ).

The present invention further relates to a removable connection element (2) that is configured to be fitted into any cavity (100, 101 , 102, 103, 108, 109, 115, 116) that is embedded into the faces (105, 107, 110, 114) of the part (1 ), i.e., it has the same symmetrical shape as the fixed connection element (104).

In the following, a preferred form of the removable connection element (2) as shown in FIG. 3 will be described. However, this shape now described does not constitute any limitation as to the shape of this element, since this element can have different shapes, as long as they correspond to the shapes of the cavities (100, 101 , 102, 103, 108, 109, 115, 116) in order to ensure its perfect fit. In this preferred form, it is constituted by walls of constant thickness, joined through an internal connecting plate (203).

Each external face (201 ) of the removable connection element (2) has four notches (204) of the concave surfaces, each having two notches that allow the full and complete fitting of two parts (1 ) in a durable and stable manner. The depth of fitting of the removable connection element (2) in the cavities (100, 101 , 102, 103, 108, 109, 115, 116) of the part (1 ) corresponds to half the depth of the removable connection element (2).

Each cavity (100, 101 , 102, 103, 108, 109, 115, 116) embedded in the faces (105, 107, 110, 114) of the part (1 ) has an elongated shape and is configured to receive a removable connection element (2) through contact between these two elements. The contact is established through a fitting made between each cavity (100, 101 , 102, 103, 108, 109, 115, 116) embedded in the faces (105, 107, 110, 114) and each removable connection element (2), wherein each cavity (100, 101 , 102, 103, 108, 109, 115, 116) embedded in the faces (105, 107, 110, 114) is configured to receive a removable connection element (2), which is carved in corresponding shape to said each cavity (100, 101 , 102, 103, 108, 109, 115, 116) embedded in the faces (105, 107, 110, 114).

In the preferred embodiment, each face (105, 107, 110, 114) of the part (1 ) has two cavities (100, 101 , 102, 103, 108, 109, 115, 116).

Still in the preferred embodiment, the removable connection element (2) is composed of a flat edge (200) that runs along the upper and lower profile of the removable connection element (2), serving as a limit for the fitting so that it is fully supported in any cavity (100, 101 , 102, 103, 108, 109, 115, 116). The flat edge (200) of the removable connection element (2) projects perpendicularly to the external face (201 ) on both sides of the removable connection element (2), said external face (201 ) is composed of two smooth parts and a concave part, which in turn has two notches (204) of the concave surface between said smooth parts, and arranged on both sides of the removable connection element (2). The smooth parts correspond to the protrusions (112) of the convex surfaces of the cavities (100, 101 , 102, 103, 108, 109, 115, 116). The protrusions (112) of the convex surfaces allow the total and complete fitting of two parts (1 ) in a durable and stable way into any cavity of the part (1 ). The removable connection element (2) also has an internal face (202) on both sides of the removable connection element (2), said internal face (202) is composed of two smooth parts and a convex part, the internal connection plate (203) is an internal connection plate which is arranged at half height of said removable connection element (2) and which makes the internal connection of the inner faces (202) of the removable connection element (2). The internal connecting plate (203) has the function of serving as an internal reinforcement of the removable connection element (2), through the union between both sides of the removable connection element (2).

The fitting of a removable connection element (2) to a cavity (100, 101 , 102, 103, 108, 109, 115, 116) of the part (1 ) is carried out as follows: placing the removable connection element (2) inside a cavity (100, 101 , 102, 103, 108, 109, 115, 116), the protrusion (112) of the convex surface of the first cavity (100) receives the notch (113) of the concave surface of the fixed connection element (104) or receives the notch (204) of the concave surface of the removable connection element (2), as it has a shape corresponding to the shape of the notch (113) of the concave surface and of the notch (204) of the concave surface. In this way, the complete alignment of the notches (204) of the concave surfaces with the protuberance (112) of the convex surfaces is obtained, thus resulting in a perfect and total fit. The notches (204) of the concave surfaces of the removable connection element (2) and the notch (113) of the concave surface of the fixed connection element (104) when connected or fitted with the protrusion (112) of the convex surface guarantee the perfect and total fit of the removable connection element (2), with the latter, totally, filling a cavity (100, 101 , 102, 103, 108, 109, 115, 116) and remaining under pressure, providing stability to the connection and joining of parts between each other.

Said fitting allows the removable connection element(s) (2) to be fitted into the cavities (100, 101 , 102, 103, 108, 109, 115, 116) of the part(s) (1 ) in an effective and lasting way, i.e. , so that the fitting between a removable connection element (2) does not disengage from a cavity (100, 101 , 102, 103, 108, 109, 115, 116) of a part (1 ), unless manual disengagement takes place, carried out by the user.

The removable connection element (2) can be any element suitable for this type of part (1 ) and can have various ways to function, as long as the symmetry of the removable connection element (2), allowing said elements to be fitted in any direction or orientation into the cavities, and the correspondence with any cavity (100, 101 , 102, 103, 108, 109, 115, 116) of the part (1 ) are maintained. By way of example, the removable connection element (2) may be in the form of connected circles, connected squares, connected diamonds, etc.; alternatively, it can have the shape of a single rectangle, or a wavy bar.

The fixed connection element (104) must have a shape similar to the shape of the removable connection element (2), which can be created with various geometric figures that are connected to each other as long as the shape is symmetrical or corresponding so that the fitting of both into a cavity can be performed safely, effectively and in a long-lasting manner, as described above.

In an embodiment of the present invention, the fixed connection element (104) can have various ways to function, as long as the symmetry of the fixed connection element (104), allowing said elements to be fitted in any direction or orientation, and the correspondence with any cavity (100, 101 , 102, 103, 108, 109, 115, 116) of the part (1 ) are maintained. By way of example, the fixed connection element (104) can be in the form of connected circles, connected squares, connected diamonds, etc., or it can be a single rectangle, or a wavy bar, as shown, in FIGS. 6 and 8. However, this element can have other shapes as long as the cavities have a corresponding shape, in order to guarantee the perfect fit in the cavities.

In another embodiment of the present invention, each face (105, 107, 110, 114) of the part (1 ) can have at least two cavities (100, 101 , 102, 103, 108, 109, 115, 116), the number of cavities (100, 101 , 102, 103, 108, 109, 115, 116) being limited to the length of each said face (105, 107, 110, 114) and provided that they are in even number.

The single-body removable connection element (2) can be a solid body, or it can be hollow. Preferably, the removable connection element (2) is hollow to allow the assembly of a lighter modular assembly system.

The notch (204) of the concave surface of the removable connection element (2) is a protrusion, or overhang, which advantageously allows fitting in the cavities (100, 101 , 102, 103, 108, 109, 115, 116) of the part (1 ) through the protrusions (112) of the convex surfaces of the same cavities (100, 101 , 102, 103, 108, 109, 115, 116).

In yet another embodiment, one part (1 ) can be connected or fitted to two parts (1 ) by means of four removable connection elements (2). A part (1 ) can also be connected or fitted to a second part (1 ) by means of at least one removable connection element (2). Alternatively, one part (1 ) can be fitted to another part (1 ) by fitting the fixed connection element (104) into a cavity. In another embodiment of the invention, one part (1 ) can be connected or fitted to five parts (1 ).

One part (1 ) can be connected or fitted to at least two parts (1 ) through at least one removable connection element (2) which is fitted into a plurality of cavities (100, 101 , 102, 103, 108, 109, 115, 116) of each of the parts (1 ), resulting in a modular assembly system of parts (1 ) as shown, by way of example, in figures 16-18.

The modular assembly system results from the assembly or fitting of at least two parts (1 ) by means of at least one removable connection element (2) of the present invention, resulting in shelves that can be stacked one on the top of the other, shelves arranged side by side, or shelves arranged in any other desired configuration. One part (1 ) can be connected to at least two parts (1 ) by fitting at least one removable connection element (2), and/or by means of at least one fixed connection element (104).

The rectangle shape presented by the part (1 ) allows it to be used in either of its two dimensions, i.e. , used in a first case, with the fourth longitudinal face (107) or fifth longitudinal face (110) resting on a surface, resulting in the assembly of modular assembly systems with a height delimited by the dimension of the sixth face (111 ) or the third face (106) resulting in an assembly with a height corresponding to a shorter edge of the part (1 ) resting on a surface; or used in a second case with its transverse sixth face (111 ) resting on a surface resulting in the assembly of modular assembly systems delimited by the dimension of the fourth face (107) or the fifth face (110) originating an assembly with height corresponding to a longest edge of the part (1 ) resting on a surface, i.e., twice the height indicated in the first case.

These embodiments are advantageous in that they allow spaces to be created for storing objects with different useful volumes, resulting in a very versatile storage of objects with different shapes and sizes.

A modular assembly system with a height corresponding to a longer edge, corresponding to a face (111 ) of the part (1 ) resting on a surface, can be constructed as follows: two removable connection elements (2) are fitted into the cavities (102 and 103 or 108 and 109) of a part (1 ), as seen in FIG. 18, until the notches (204) of the concave surfaces are aligned with the protrusion (112) of the convex surfaces, thus ensuring that the part (1 ) and the removable connection elements (2) do not unintentionally disassemble. Then, after having obtained a part (1 ) with two removable connection elements (2), these will be fitted to another set of one part (1 ) with two removable connection elements (2) or just to one individual part (1 ) through the fitting of removable connection elements (2), or through the fixed connection element (104). The choice between the first or the second depends on the type of assembly required.

A modular assembly system with a height corresponding to a shorter edge, corresponding to a face (107, 110) of the part (1 ) resting on a surface, can be constructed as follows: two removable connection elements (2) are fitted in the cavities (100 and 101 or 115 and 116) of a part (1 ), as seen, for example, in FIG. 19 a), bottom drawing. Each removable connection element (2) is fitted into the cavities (100 and 101 or 115 and 116) until alignment of the notches (204) of the concave surfaces with the protrusions (112) of the convex surfaces is obtained, thus ensuring that the part (1 ) and the removable connection elements (2) do not unintentionally disassemble.

Then, after having obtained a part (1 ) with two removable connection elements (2), these will be fitted to another set of one part (1 ) with two removable connection elements (2) or just to one individual part (1 ) through the fitting of removable connection elements (2), or through the fixed connection element (104). The choice between the first or the second depends on the type of assembly required.

A fifth part (1 ) can also be fitted into the assembly system with a height corresponding to a longer edge of the part (1 ) resting on a surface, by fitting the cavities (100 and 101 or 115 and 116) of the face (105 or 114) on the fixed connection elements (104) on the third face (106) of the first two parts (1 ), resulting in a modular assembly system with a shelf open only on one side, according to, for example, FIG. 18. The fifth part (1 ) guarantees greater support and cohesion in the modular construction.

In another embodiment of the present invention, the parts (1 ) are arranged stacked on top of each other and connected by fitting with the removable connection elements (2). In another embodiment of the present invention, the parts (1 ) are connected, by fitting, side by side. In yet another embodiment, the parts (1 ) are arranged, connected by fitting, in any way that allows creating a space suitable for use as storage of objects.

The modular assembly system of parts (1 ) has dimensions that allow it to be adaptable to the space where it will be placed, both in terms of size and format. The modular assembly system of parts (1 ) of the present invention allows the assembly and disassembly for the necessary or desired times, adding or removing parts (1 ) to said modular assembly system of parts (1 ), creating spaces with the intended dimensions and shapes. The modular assembly system of parts (1 ) and removable connection elements (2) is used to organise closed cabinets or open shelves.

In another embodiment, the removable connection elements (2) can be removed from the part(s) (1 ) for aesthetic reasons and can be used in the assembly of several different formats of modular assembly system of parts (1 ).

The removable connection element (2) has the advantage of providing numerous possibilities for different models of modular assembly system of parts (1 ), in which one or more parts (1 ) can be removed if necessary, or to make the modular assembly system of parts (1 ) more attractive if placed on an open shelf.

The part (1 ) is produced by a process of plastic injection in a mould, in which the raw material is inserted into a plastic injection machine, the raw material is melted and is injected into a previously prepared mould for this purpose. The part (1 ) can be produced in one of the following materials: recycled plastic material, woods, acrylics, composites, resins and the like such as Corian®. Said part (1 ) can also be produced with other materials, such as metal, hardboard, according to the intended use.

In a preferred embodiment, the part (1 ) is produced in recycled polypropylene. In this way, it can be recycled, not generating waste in its production, in addition to having a faster production process. The removable connection elements (2) are produced in the same materials as the part (1 ) and through the same processes.

The present invention has the following advantages:

- It adjusts to any existing space.

- It allows the creation of more spaces upwards (vertical direction) or to the side (horizontal direction), for a better use of the existing space.

- It is due to the interrelated set of part (1 ) - removable connection element (2) so that it is possible to assemble and disassemble shelves without using tools or accessories, avoiding costs and material waste, in addition to obtaining different configurations of modular assembly systems.

- It is easy to assemble, intuitive and accessible to anyone.

- The part (1 ) has reliefs, such as bas-reliefs, the notch (113) of the concave surface of the fixed connection element (104); and high reliefs, such as the protrusions (112) of the convex surface of cavities, being easily perceptible by the blind.

- It has easy disassembly for adjustments, alterations or additions.

- In the case where the parts (1 ) form modular assembly systems with removable connection elements (2), said parts (1 ) and the removable connection elements (2) are equal to each other regarding a certain dimension facilitating assembly, disassembly and use of the parts (1 ) and of the removable connection elements (2) to create a new organisation of spaces.

- It allows the possibility of purchasing additional parts (1 ) and removable connection elements (2) to add to a modular assembly system, without wasting the parts (1 ) and the removable connection elements (2) previously purchased, providing the possibility of purchasing only the number of parts (1 ) and removable connection elements (2) necessary for the intended purpose.

- The parts (1 ) and the removable connection elements (2) can be used inside cabinets, or in open shelves, fitting into any furniture. - Ease of production as the part (1 ) and the removable connection element (2) are produced in a single material.

- The parts (1 ) and the removable connection elements (2) are small, facilitating transport both in terms of space and cost.

- The part (1 ) and the removable connection elements (2) are ecological products made from recycled materials, avoiding waste of components in production and assembly, saving shipping space in boxes or containers.

The present invention can also be implemented in the form of a kit constituted by a closed package containing at least one part (1 ) and at least two removable connection elements (2). In one embodiment, the kit contains five parts (1 ) and ten removable connection elements (2).

These kits have the advantage that the user can assemble a modular assembly system with a shelf, being able to later obtain a number of parts (1 ) and additional removable connection elements (2) that are necessary for the intended purpose, for example, assembly of a modular system with several shelves.

MODULAR ASSEMBLY EXAMPLES

Some examples of modular assembly systems according to the present invention are illustrated below, only by way of example.

Example 1

One possible combination is shown in FIG. 19. To assemble this combination, 13 parts (1 ) and 22 removable connection elements (2) are used.

In a first step, two parts (1 ) fitted together longitudinally are placed by means of a removable connection element (2) inserted in the second cavity (103) of the fourth face (107) of a first part (1 ) and in the second cavity (109) of a second part (1 ), and a second removable connection element (2) inserted in the first cavity (102) of the fourth face (107) of the first part (1 ) and in the first cavity (108) of the fifth face (110) of the second part (1 ), forming a square set (1 +1 +2+2). This process is repeated four times. Subsequently, two square sets (1 +1 +2+2) are placed vertically, side by side, with the fixed connection elements (104) facing the first face of the part (1 ), that is, in the first face (105), forming two walls, then a square set is placed horizontally, over the two walls, fitting each of its four cavities, in the first cavity (100) and in the second cavity (101 ), both of the first face (105) of each part (1 ), which face the second face of the part (1 ), that is, the second face (114), on the fixed connection elements (104) of the two walls. Four removable connection elements (2) are then inserted into the four cavities, two first cavities (108) and two second cavities (109), both of the fifth face (110) of each wall that is facing the rear face, vertically and in the four cavities, in the first cavity (100) and in the second cavity (101 ), both of the first face (105) of each part (1 ) of another square set. Then, four more removable connection elements (2) are inserted in the four cavities, in the first cavity (115) and in the second cavity (116) both of the second face (114) of each part (1 ) that are facing the first face of the part (1 ), i.e., the first face (105) in the square set that is horizontal, and in the first cavity (102) and the second cavity (103), both of the fourth face (107) of two new parts (1 ) so that they are vertical, side by side, with the fixed connection element (104) facing the rear face. Soon after, a part (1 ) is placed on the rear face, fitting each of the two cavities, in the first cavity (100) and in the second cavity (101 ) both of the first face (105) on the fixed connection element (104) of each part (1 ) placed earlier.

The assembly ends by fitting four removable connection elements (2) in the first cavity (108) and in the second cavity (109), both of the fifth face (110) of the two parts (1 ) placed vertically and in the four cavities, in the first cavity (100) and in the second cavity (101 ), both of the first face (105) of each part (1 ) of a new square assembly (1 +1 +2+2) placed on top and horizontally. There are reference numbers described here, but not visible in FIG. 19, as will naturally be understood.

Example 2

One possible combination is shown in FIG. 20. To assemble this combination, 17 parts (1 ) and 32 removable connection elements (2) are used.

In a first step, two parts (1 ) fitted together longitudinally are placed by means of a removable connection element (2) which is inserted in the second cavity (103) of the fourth face (107) of a first part (1 ) and in the second cavity (109) of the second part (1 ), and a second removable connection element (2) inserted in the first cavity (102) of the fourth face (107) of the first part (1 ) and in the first cavity (108) of the fifth face (110) of the second part (1 ), forming a square set (1 +1 +2+2). This process must be repeated three times. Then, one should work on a horizontally square set with its four cavities - a first cavity (100) and a second cavity (101 ), both of the first face (105) of a part (1 ) and a first cavity (100) and a second cavity (101 ) of another part (1 ) facing the first face of the part (1 ), that is, on the first face (105) - which will serve as a base and where four removable connection elements (2) will be fitted in each of these same cavities. Subsequently, two parts (1 ) will be placed vertically, side by side, with the fixed connection elements (104) facing the rear face, between the two parts (1 ) that were placed side by side vertically, fitting their cavities - the first cavity (102) and the second cavity (103), both of the fourth face (107) of each part (1 ) that were facing the second face of the part (1 ), that is, on the second face (114) - on the four removable connection elements (2) placed earlier. Then, a part (1 ) is placed on the rear face, between the two parts (1 ) that were placed side by side vertically, fitting their two cavities in the first cavity (115) and in the second cavity (116) both of the second face (114) on the two fixed connection elements (104) of the two parts (1 ). In these same parts (1 ) two removable connection elements (2) are inserted in the two cavities, that is, in the first cavity (108) and in the second cavity (109), both of the fifth face (110) of each part (1 ) and a new square assembly (1 +1 +2+2) will be fitted from the top in these removable connection elements (2), using four cavities, the first cavity (115) and the second cavity (116), both of the second face (114) of each part (1 ) that lay face down on the second face (11 ) of each part (1 ).

The assembly is concluded by repeating the second step twice. There are reference numbers described in this example, which are not visible in FIG. 20, as will naturally be understood.

Example 3

One possible combination is shown in FIG. 21. To assemble this combination, 11 parts (1 ) and 18 removable connection elements (2) are used.

Two parts (1 ) fitted together longitudinally are placed by means of a removable connection element (2) inserted in the second cavity (103) of the fourth face (107) of a first part (1 ) and in the second cavity (109) of the second part (1 ), and a second removable connection element (2) is inserted in the first cavity (102) of the fourth face

(107) of the first part (1 ) and in the first cavity (108) of the fifth face (110) of the second part (1 ), forming a square set (1 +1 +2+2). This process is repeated three times. Then, two square sets (1 +1 +2+2) are placed vertically and side by side, with the fixed connection elements (104) facing upwards, that is, the third face (106) is upwards and another square assembly (1 +1 +2+2) is placed on the rear face of the assembly fitted by means of four removable connection elements (2) in four cavities - in the first cavity

(108) and in the second cavity (109), both of the fifth face (110) of each of the two parts (1 ) that were placed vertically and facing the rear face of the assembly and in the four cavities - in the first cavity (100) and in the second cavity (101 ), both of the first face (105) of each part (1 ) of the respective square set and in this same square set, two removable connection elements (2) are inserted in the first cavity (108) and second cavity (109), both of the fifth face (110) that are facing towards the first face of the part (1 ), i.e. , on the first face (105). Then, two parts (1 ) placed vertically and side by side and with their fixed connection elements (104) facing the rear face of the assembly, fit their cavities - in the first cavity (102) and in the second cavity (103), both of the fourth face (107) of each part (1 ) on the four fixed connection elements (104) of the two square assemblies (1 +1 +2+2) which are vertically arranged. Subsequently, a new part (1 ) is placed on the rear face of the assembly, fitting its two cavities, the first cavity (102) and the second cavity (103), both of the fourth face (107) in the two removable connection elements (2) previously inserted and fits their cavities, the first cavity (115) and the second cavity (116), both of the second face (114) into the fixed connection elements (104) of the two parts (1 ) placed vertically. In these same two parts (1 ) are inserted into their cavities, the first cavity (108) and the second cavity (109), both of the fifth face (110), four removable connection elements (2). The assembly ends with the placement of a last square assembly (1 +1 +2+2) on top of the assembly carried out so far, fitting its four cavities - the first cavity (115) and the second cavity (116), both of the second face (114) of each part (1 ) which are facing the second face of the part (1 ), i.e., on the second face (114), on the four previously placed removable connection elements (2).

All changes, as long as they do not modify the essential features of the claims that follow, are to be considered within the scope of protection of the present invention.
