Abstract

The invention relates to a foldable item of furniture consisting of two outer panels and one inner central sliding panel, each outer panel having four longitudinal folds forming two internal vertices and two external vertices, substantially orthogonal to one another. The two internal vertices form adhesive tabs by means of which the two outer panels are permanently joined. At least one outer panel has at least one system of cuts and folds which, when the item of furniture is unfolded, forms a shelving unit having a rear support that is permanently joined to the inner central sliding panel and a front support that is generated from the outer panel by means of a fold. Finally, the inner central sliding panel moves longitudinally to fold and unfold the item of furniture.

Description

FOLDABLE FURNITURE

1. Field of the Invention The present invention relates to folding furniture systems, particularly furniture made of laminated materials that allow die-cutting, such as corrugated cardboard with shelves for the location of objects that are assembled in a single movement.

2. Description of the state of the art

Corrugated cardboard is a structural material, widely used in the development of packaging for packaging and the like. Its low price, structural qualities and the ease with which it can be handled have resulted in a large number of new applications in the manufacture of different products. The use of this material in furniture with shelves is widely applied given its great structural potential and its ability to be printed, generating furniture for advertising and very aesthetic purposes. They are generally furniture with cubic shapes and shelves for the location of products. Furniture can be very bulky when armed, which increases transportation costs, therefore they tend to be deployed to be assembled and folded at the installation point. The great limitation of this furniture is that its multiple parts and the complexity of folding require a person trained in its assembly so that it is folded and assembled properly.

Patent document No. US US2010 / 0006529 claims a furniture in corrugated cardboard, foldable in cubic form, with two shelves fronts and with the following components: a front panel, a rear panel, two side panels and a sliding central panel. It has two fronts with exhibition spaces or shelves that are generated from cuts made in the front and rear panels that in turn are fixed to the sliding panel through glue tabs. Said sliding panel controls the folding and unfolding of the furniture through a vertical movement and has anchor tabs that are fixed in perforations made in the side panels to secure the furniture when it is armed. The whole development is done in two cardboard sheets, the first sheet forms the front, rear panel and side panels, and the second sheet constitutes the sliding central panel. One of the disadvantages of this furniture is that its folding requires the assembly of multiple tabs to fix the furniture when it is folded. These tabs could be mistreated to be reused, causing the furniture to fail operationally. On the other hand, the way in which the shelves are developed generates weak surfaces that generate structural problems to support the weight of non-light objects, which would limit the functionality of the furniture. A person versed in this technique could solve this structural problem by generating glue tabs on the sides, a feature that does not allow the furniture to unfold or fold again.

Patent document No. US 2010/0051568 Al claims a furniture in corrugated cardboard, foldable, with cubic form and with the following components: a front panel, a back panel and two side panels. The furniture has exhibition spaces that come out of cuts made on the front panel, which when folded inwards generate the product display spaces and some windows on the sides, these in turn are fixed by means of anchor tabs to the back panel All the furniture is raised in a single unfolded sheet. According to the above, it is clear that the trend should be directed to systems that with a single movement allow the folding of the furniture, and at the same time provide solutions with strength and structural stability, rigidity, longer life cycle and ease in assembly. Although the state of the art discloses folding corrugated cardboard furniture that allows its transport in a folded way, said furniture does not allow easy assembly at the installation site and still have impractical mechanisms for folding, since they have structural flaws that limit the load capacity of shelves. Therefore, there is a need for furniture that can be transported deployed and allowed to be folded at the installation site, where the furniture allows folding and unfolding multiple times, and that is easy to manufacture in such a way that it generates optimal use of the material to reduce waste in its manufacture. 3.

4. BRIEF DESCRIPTION OF THE INVENTION The present invention is a folding furniture to place on a surface, with at least one face, at least one shelf and an assembly system that works with a sliding central panel that moves vertically by folding and unfolding the furniture. , allowing the assembly of the furniture in the place where it will be installed and facilitates its transport when being packed folded.

Specifically, the present invention discloses a folding piece of furniture, characterized in that it comprises two exterior panels and an internal sliding central panel, where Each outer panel has four longitudinal folds that form two internal vertices and two external vertices, substantially orthogonal. The two internal vertices form glue tabs by means of which the two outer panels are joined and where at least one outer panel has at least one system of cuts and folds that form a shelf with a back support that permanently attaches to the sliding central panel interior and an anterior support that joins the outer panel by folds; and where the inner sliding central panel moves longitudinally to fold and unfold the furniture. 5. Detailed description of the invention

The present invention discloses a folding piece of furniture that simplifies the folding and unfolding of folding furniture with shelves, allowing its assembly to be a single movement action. This allows to improve its transport and storage capacity by being flat eliminating the need to use skilled labor.

The invention is intended to be manufactured in sheet materials that allow them to be punched and foldable, as for example, without being limited to the following materials: cartons of various categories and plastic sheet materials.

Referring to Figure 1, an embodiment of the furniture of the present invention is observed, which is composed of 3 pieces assembled together, thus: two outer panels (01) and an inner sliding central panel (02) cut from a sheet of folding material (as shown in Figure 2).

As shown in Figures 1 and 2, each outer panel (01) has four longitudinal folds that form two internal vertices (3) and two external vertices (4), where all the vertices are parallel to each other. In the present invention, the term fold should be understood as a linear mark on the material, which weakens the material in order to generate a bend. Referring to Figure 2, The two internal vertices (3) of the outer panels (01) form glue tabs (05) where the two outer panels (1) are joined, either through a mechanical assembly or with a glue, ensuring that the two outer panels (01) are joined together.

Referring to Figures 1 and 2, the furniture of the present invention has at least one cutting and folding system (06) that allows generating shelves (07). A shelf should be interpreted as a surface placed horizontally on a piece of furniture for the location of objects. The system of cuts and folds (06) that can be interchangeably in at least one of the outer panels (01) generates a shelf (07), which folds and unfolds at the moment when the inner sliding central panel (02) is it moves longitudinally, as shown in Figure 3, allowing objects to be placed on the shelf (07) when the furniture is deployed. Referring to Figure 1, the shelf (07) has a rear support (08) that joins the central sliding panel (02) either by a mechanical assembly or attached when the central sliding panel (02) is inserted for the furniture assembly. This joint is what controls the folding and unfolding of the shelf (07) when the sliding central panel (02) is displaced, as seen in Figure 3, where the furniture assembly is shown both in a perspective sequence and in a sequence of cuts. There it is observed how with the sliding of the central sliding panel (02), the shelf (07) unfolds.

Referring to Figure 1, the shelf (07) has a previous support (09) generated by a fold that allows it to remain attached to the outer panel (01) from which it was built and avoiding tears that can be generated in joints or cuts, on the other hand this previous support (09) works as a pivot when the furniture is folded and unfolded. Referring to Figure 2, in one embodiment of the folding furniture of the present invention, the system of cuts and folds (06), has a hexagonal shape, located in such a way that the two vertical diagonals of the hexagon are defined as the lines of union of its non-consecutive vertices. Said diagonals are collinear to the two outer vertices (04) of the outer panel (01) in which the system of cuts and folds (06) is contained, that is, the two vertices of each vertical diagonal (13), are inscribed in the two external vertices (04).

According to Figure 2, said hexagonal shaped cut and fold system (06) of the preferred embodiment of the invention is comprised of:

Three main cuts (10) inscribed on the 3 upper sides of the hexagon and 3 three main folds inscribed on the 3 lower sides of the hexagon, where the horizontal fold generates the anterior support (09) of the shelf and the two inclined folds generate lateral supports external (11) for the shelf.

An internal edge (12) parallel and equidistant from the upper side of the hexagon, thus generating the rear support (08) of the shelf (07) that is permanently attached to the central sliding panel (02), as shown in Figure 1.

Two collinear folds to the vertical diagonals (13) of the hexagon, ranging from the fold that generates the anterior support (09) to the parallel internal edge (12), thus generating two other internal lateral supports (14) for the shelf (07).

Two collinear cuts (15) to the vertical diagonals of the hexagon, which are comprised from the upper horizontal side of the hexagon to the parallel internal edge (12) and thus finish delimiting the rear support (08) of the shelf.

Two cuts (16) that go from the vertices of the parallel internal edge (12) to the external vertices of the hexagon and thus finish releasing the system of cuts and folds (06) of the outer panel (01) and that this is joined only in the folds and thus allow the shelf (07) to function when the furniture is folded and unfolded.

Two small cuts (17) that start from the outer vertices of the hexagon. Its function is to reduce the surface tension at this point to avoid tearing when the furniture is folded and unfolded. In a second embodiment of the invention, such as that shown in Figures 4 and 5, the cut and fold system (06) has a hexagonal shape, as shown in Figure 5, located such that the two vertical diagonals of the Hexagon, where the vertical diagonals of the hexagon are defined as the joining lines of its non-consecutive vertices, are collinear to the two external vertices (04) of the outer panel (01) in which the cut and fold system (06) is contained ). Said system of cuts and folds (06), as shown in Figure 5, can have: · A cut (18) and four cuts (19) inscribed on the top five sides of the hexagon, where the cut (18) is the rear support point (08) of the shelf (07) and where a fold (20) inscribed on the horizontal lower side of the hexagon generates the anterior support (09) of the shelf (07).

• Two cuts (21) inscribed in the vertical diagonals of the hexagon, in order to free the shelf (07) so that it remains joined only by the posterior (08) and anterior (09) support points, allowing its folding and unfolding. This modality does not have any lateral support on the shelf. In a third embodiment of the invention, as shown in Figures 6 and 7, the cut and fold system (06) has a hexagonal shape, as shown in Figure 7, located in such a way that the two vertical diagonals of the hexagon, where the vertical diagonals of the hexagon are defined as the joining lines of its non-consecutive vertices, are collinear to the two external vertices (04) of the outer panel (01) in which the system of cuts and folds ( 06). Said system of cuts and folds (06) is equal to the system of cuts and folds (06) of the preferred mode, but has two empty sections (22), as shown in Figure 7, in this way this mode has side supports (23) for the shelf (07) but decrease its length compared to the preferred mode.

In a preferred embodiment of the invention, such as that illustrated in Figure 8, the furniture has four shelves (07) on each of its two panels exteriors (01), wherein said shelves (07), are formed by 4 systems of cuts and folds (06) located longitudinally and equidistant in the exterior panels (01), as shown in Figure 9. This embodiment illustrates a piece of furniture with four shelves on its front face and four shelves on its back face

For this preferred embodiment, as illustrated in Figure 9, two outer panels (01) and two central sliding panels (02) are needed, all these pieces must be cut from a sheet material that allows to be punched. In Figure 10, an exploded view of the assembly of the multiple parts that make up the furniture can be seen. The two outer honeycombs (01) face each other and are joined by means of glue tabs (05). Each outer panel (01) joins a central sliding panel (02) by means of the rear support points (08) that each cut and fold system (06) possesses, where in this preferred embodiment, the surface of the points Rear support (08) is attached to the central sliding panel (02). In this preferred embodiment, as illustrated in Figure 9, the rear support points (08) have two tooth-shaped cuts (24) and the central sliding panels have rectangular grooves (25), where said shaped cuts of teeth (24) of the outer panel (01) fit the rectangular grooves (25) of the central sliding panel (02). In this way, a guide is generated to correctly join the outer panels (01) with the sliding central panels (02), as illustrated in Figure 10.

As seen in Figure 8, when the two outer panels (01) are joined and each outer panel (01) is attached to a sliding central panel (02), as described above, the furniture is left with two outer panels (01 ) and with a double wall sliding central panel (02) due to the union of the two sliding central panels (02) that are needed for the preferred mode and thus generate more firmness and structural rigidity in this piece. In Figure 11, it can be seen how the central sliding panel (02) is responsible for generating the furniture assembly, by means of its displacement.

In the preferred embodiment, as illustrated in Figure 9, the systems of cuts and folds (06), have a cut that forms borders (26) which serve to stop the objects supported on the shelves. In Figure 12, the systems of cuts and folds (06) of the outer panel (01) can be modified in their angles (27) and in their distance (28) which allows generating different inclinations in the shelves (07). It should be understood that the present invention is not limited to the modalities described and illustrated, since as will be evident to a person versed in art, there are possible variations and modifications that do not depart from the spirit of the invention, which is only found defined by the following claims.
