Description

Convertible cardboard box on desk table.

Object of the invention

The present invention relates to a cardboard box that has been specially designed to contain inside a large number of packages, also cardboard, transformable in other elements intended to together form the furniture necessary to assemble a classroom. The packages included inside the box are convertible into desks, preferably in a number between 12 and 30 units and, at least one, on a blackboard. The container box itself, once empty, is transformed into a table, with which in a single box it is possible to include: a table, a blackboard and several desks, allowing to form a basic classroom from a single package.

Background of the invention

Cardboard, as a lightweight, recyclable and economical material, has been and is one of the most used materials in recent decades in the furniture and decoration sector. The furniture design made of corrugated cardboard had its main exponent in the figure of Frank Gehry, an American architect who, between 1969 and 1973, designed a line of pressed cardboard furniture consisting mainly of chairs, tables and armchairs. With the use of this everyday material in these small-scale designs, it brought a new aesthetic character to the pieces of furniture and opened the way for the constructive exploration of furniture in cardboard. From these designs of cardboard furniture, the models of furniture in corrugated cardboard have been varied, from pieces constituted by the assembly of elements to the resolved ones by means of a single plate cut, split and folded.

In the patent literature there are several references related to this type of furniture: U0164227, ES1027584 refer to cardboard tables. Document U0164229 refers to a cardboard desk. For their part, documents ES-1027341, ES-1043492 and ES-1057128 deal with cardboard chairs.

Description of the invention

The invention consists of a cardboard box convertible into a desk, which is obtained from a single sheet or cardboard sheet, conveniently cut and marked with various creasing lines that allow folding along them, which delimit several areas in said sheet, which will eventually constitute parts of the box or table.

This sheet, from a first rectangular central zone, has several adjacent zones, the result of extending longitudinally and transversely in both directions, which fold orthogonally to form a parallelepiped thereon. Firstly, the sides of said sheet are folded and folded at a right angle towards the inside, above said central area, the overlaps of these sides are folded at a right angle towards the interior by dividing the parallelepiped longitudinally by a double central partition.

This parallelepiped constitutes a box, capable of containing various elements or objects. The box, once filled, closes with the two lateral zones prolonging the central zone in the longitudinal direction, which overlap and couple each other by means of a window-flap set or any other solution that allows the box to be temporarily closed.

The aforementioned parallelepiped can also give rise to a table, it is enough to fold the two lateral zones prolonging the central area in a longitudinal direction, on the lateral partition thereof, the first annexed on the outside and the extreme annexed on the inside. For this purpose, this extreme zone has an intermediate cut in the longitudinal direction that divides it into two, so that the dividing partition in the parallelepiped is in between. In this way an inverted table is mounted, which logically only needs to be turned around to use it as such a table.

To facilitate its use as a table, the existence of two lateral openings is planned, from the floor to an area close to the lid, which allows users to introduce the legs under the table.

According to one of the objectives of the invention, the box is designed to include several desks and optionally a waxing, all elements that allow the formation of a classroom. Once it has been completely emptied, the box is transformed into a table and thus a complete classroom is composed, easy to assemble and transport due to its low weight and volume.

The only material with which this table-box is manufactured is cardboard, which is an economical, sustainable and recyclable product. On the other hand it is a resistant and durable material, which can be easily cut or stamped to achieve series production elements, in which you can also rethink its configuration, either separately or in combination with other complementary elements. cardboard, in order to get the most out of the starting cardboard sheet, which promotes the minimum consumption of raw material used.

Figures 1 to 8 show the sheet (1) as it is folded to form the table (2), represented in an inverted position in Figure 7 and in the position of use in Figure 8.

Figures 9 to 12 link the series with Figure 5, showing in succession the steps to be taken to obtain a box (4) from the sheet (1).

Figure 13 represents a plan view in greater detail of the sheet (1), which constitutes the only element necessary for the realization of the box or table object of the invention.

Preferred Embodiment of the Invention

As can be seen in the referenced figures, the table-box of the present invention is constructed from a single cardboard sheet (1), which has various cuts and folding lines that delimit a series of areas that will be described in detail below. .

We start from a central area (11), with a quadrangular configuration, which extends longitudinally in both directions in paths (12-13) of similar size and configuration, which are separated from each other by transverse folding lines. Both the central zone (11) and the two zones (12) adjacent to it extend laterally in as many (three) zones (14-15-16), of which the intermediate (14) is connected to the central zone by a bending line, while the zones attached to it form flaps (15-16), which are connected to the respective intermediate zone (14) by a bending line (145-146), but are separated by a cut line (153-163) of the respective annexed zones (12).

Each of the flaps (15-16) has a central folding line (151-161) in which there are two cuts in opposite directions. In the flaps (15) the cut (152) goes from the outer edge to approximately the center and in the flaps (16) the cut (162) goes from the separation line with the attached area

(12) to the center.

The flaps (15-16) are facing laterally, so that the cuts described (152-162) are opposed on the same side and on the opposite flaps of opposite sides, so that when folding the set of flaps on both sides upwards and towards the inside of the sheet these cuts intersect by joining the respective flaps (15-16) through these intermediate cuts.

With this configuration and the cardboard sheet is placed on the floor or on a surface (see figure 1), the lateral zones (14-15-16) are folded upwards until they are placed in an upright position, then they are folded at a right angle side flaps (15-16) and the opposite sides are coupled to each other through the cuts (152162) that they present (see figures 2 and 3). The end part of the flaps (15-16) fold inwards so that they are attached to each other, the assembly forming a superiorly open parallelepiped, which is divided longitudinally by a double intermediate partition (18) as shown in the figure. Four.

From this configuration we are able to form either a box (5) or a table (2).

Following the sequence of figures 5 to 8, the formation of the table (2) can be clearly seen. First, the two lateral zones (12-13), which are prolongation of the central zone (11) in the longitudinal direction, are closed on the lateral partition formed by the coupling between the respective zones (15-16) and then the surfaces or extreme flaps (13) on the intermediate partition (18), piercing the flaps (13), thanks to the fact that they have a central cut (131) that divides them in two in a longitudinal direction, until they are attached to the inner wall of the formed parallelepiped , which is open on the upper face.

In order to facilitate the placement of the user's legs under the table, it is provided that the side flaps (14) have a large central window (141) from the outer edge, which when the table occupies its functional position (figure 8 ), determine gaps on two opposite sides. Since the use of this element will first be a box for transporting the classroom and then, at destination, a table, this window (14) can be delimited by a cut line; in principle it would take its place while it is mounted as a table, this area being removed when the table is to be formed.

Following from Figure 4, which links to the sequence of Figures 9 to 12, the formation, filling and closing of the box (5) is observed. The two spaces of the parallelepiped are filled with other boxes (3-4), which in the application for which this invention has been designed contain and / or give rise to a series of desks (3) and a waxing or slate (4) . Once the box has been filled, it closes when the two lateral zones (12-13) are folded, which are a prolongation of the central zone (11) longitudinally on the annexed lateral partition, the extreme zones (13) forming a double lid for this box.

The zones (13) have respectively two extreme flaps (133), in correspondence with two windows (132) located in the bending line and union with the annexed zones (12), which allow their coupling by means of this window flap set , which guarantees the closing of the box (5).

This double set of flaps (133) and windows (132) existing in the area (13) also allows to secure the 5 partitions of the sides of the table (2) when engaging in the last phase of formation of the same, as has been explained above.

Once the nature of the invention has been sufficiently described, as well as a preferred embodiment, it is stated for the appropriate purposes that the materials, shape, size and arrangement of the described elements may be modified, provided that this does not imply an alteration. of the characteristics
