DETAILED DESCRIPTION OF THE INVENTION

(14) The object of the invention relates to a piece of modular furniture, such as a table or shelving, of the types used for material storage at both domestic and industrial levels, which furniture comprises a set of elements (1, 3, 5) intended for being coupled by fitting to one another, and therefore without having to use coupling elements such as screws, nails, pins, or tools for applying said coupling elements.

(15) The modular furniture comprises at least two pairs of vertical posts (1), wherein each vertical post (1) has housings (2), horizontal slats (3) having conformations (4) configured for being introduced in the housings (2) of the vertical posts (1), and at least one shelf (5) having indentations (6) configured for fitting to the vertical posts (1).

(16) Therefore, when using the furniture, i.e., when the user couples the set of elements (1, 3, 5) making up the furniture to one another, each pair of vertical posts (1) is joined by the horizontal slats (3), and the conformations (4) of each horizontal slat (3) are introduced in the housings (2) of the vertical posts (1), whereas the shelves (5) are supported on the horizontal slats (2) with the vertical posts (1) fitted in the indentations (6) of the shelves (5), a suitable strength and rigidity of the furniture thereby being assured.

(17) When several shelves (5) are used, the furniture corresponds to a shelving such as the one depicted in the drawings, whereas when one shelf (5) is used, the furniture corresponds to a table.

(18) The length, width, and thickness of the vertical posts (1), horizontal slats (3), and shelves (5) are selected depending on the requirements asked of the furniture, such as furniture height, depth, and rigidity.

(19) The elements (1, 3, 5) of the modular furniture are preferably made of wood as it has a good price and appearance, although they may be made of any other material known in the furniture sector, such as metal or plastic.

(20) The housings (2) of the vertical posts (1) have a shape complementary to the conformations (4) of the horizontal slats (3), and the indentations (6) of the shelves (5) have a shape complementary to the cross-section of the vertical posts (1), such that press-fitting is established between said elements. Minimum tolerances between said elements are selected to assure a tight-fitted joining that is, however, sufficient to make it easier to disassemble the furniture.

(21) As seen in FIG. 5, the vertical slats (1) have a rectangular cross-section with the housings (2) on one of their faces. The housings (2) are separated from one another by a distance according to the required height between shelves (5).

(22) In this type of furniture, it is suitable for the lowermost shelf (5) of the furniture to be separated at least 10 cm from the floor to enable cleaning or to prevent contact with water that may spill under the shelving, so the housings (2) of the vertical posts (1) are preferably arranged with a separation of at least 10 cm with respect to one of the ends of each vertical post (1).

(23) The housings (2) of the vertical posts (1) preferably have a rectangular configuration, although they may have a circular configuration or any other polygonal configuration; in any case, the housings (2) preferably have a shape complementary to the conformations (4) of the horizontal slats (3) to assure a tight-fitted joining.

(24) FIG. 6 shows an embodiment of the horizontal slats (3), wherein each conformation (4) is arranged at one end of the horizontal slats (3), and the conformations (4) have a cross-section that is smaller than the cross-section of the horizontal slats (1).

(25) FIG. 7 shows another embodiment of the horizontal slats (3), wherein each conformation (4) is arranged at one end of the horizontal slats (3), the conformations (4) having a cross-section which is the same as the cross-section of the horizontal slats (1), such that the horizontal slats (3) have an identical cross-section along their entire length.

(26) According to one embodiment, the vertical posts (1) of each pair are joined by means of the horizontal slats (3), such that they form a single, side ladder-like assembly unit. According to this embodiment, the conformations (4) of the horizontal slats (3) can possibly be joined to the housings (2) of the vertical posts (1) by means of an adhesive. In any case, by using minimum tolerances a perfect anchoring is achieved and no adhesive is necessary, but in some cases in which tolerances are not suitable, the adhesive can assure the fixing. With these embodiments, the vertical posts (1) are supplied, joined to the horizontal slats (3), in a flat packaging of reduced thickness in which the shelves (5) are also included.

(27) When the vertical posts (1) are joined by the horizontal slats (3), to assure the assembly of the shelves (5), the square or rectangular space formed between said elements (1, 3) must be large enough for a shelf (5) to be introduced therethrough. In other words, the diagonal of the square or rectangular space formed by the vertical posts (1) with the horizontal slats (3) must be greater than the width of the shelf (5), see FIG. 15.

(28) With the embodiment in which the vertical posts (1) are supplied individually without being joined by the horizontal slats (3), the user can arrange the horizontal slats (3) in the housings (2) of the vertical posts (1) as desired, where he or she can therefore choose the height at which the shelves (5) are arranged in the furniture. In any case, all the elements (1, 3, 5) of the modular furniture are supplied individually but included in a flat packaging of reduced thickness.

(29) FIG. 1 shows an embodiment of the modular furniture of the invention with shelves (5) such as those depicted in FIG. 4. This embodiment is conceived for positioning the furniture supported against a wall, for which the shelves (5) have indentations (6) arranged equidistant from one another on the larger sides, where the indentations (6) are arranged at least at the ends of the shelves (5). The shelves (5) therefore do not protrude outwardly with respect to the vertical posts (1), the furniture being fitted against the wall where it is arranged and the vertical posts (1) abutting with the wall.

(30) FIG. 8 shows another embodiment of the modular furniture of the invention with shelves (5) such as those depicted in FIG. 9. This embodiment is conceived for positioning the furniture in an intermediate location without being supported against the wall, such that in this embodiment the shelves (5) protrude laterally from the vertical posts (1) to assure a suitable securing of the shelf. (5). To that end, the shelves (5) have indentations (6) arranged equidistant from one another on the larger sides, the indentations (6) being arranged at least at the ends of the shelves (5) but with a slight separation with respect to the ends.

(31) FIGS. 1 to 9 show vertical posts (1) with a rectangular cross-section, although they can have another configuration such as a square or another polygonal configuration, such as the irregular polygonal configuration in the shape of a rectangular trapezoid shown in FIGS. 10, 11, and 12, in which the vertical post (1) has a beveled side at least in the area where it fits with the indentations (6), such that with the indentation (6) having a complementary shape, a dovetail-type joint is established between the vertical post (1) and the indentation (6) of the shelf (5), assuring complete anchoring.

(32) Each vertical post (1) therefore has four sides, one of them having a beveled shape, such that the beveled side forms an angle with respect to the contiguous side smaller than 90, and preferably smaller than 80. The shelf (5) therefore cannot slide horizontally with respect to the vertical post (1), which could indeed happen if the vertical post (1) has a rectangular or square cross-section with angles equal to 90 between its sides.

(33) FIG. 12 shows a cross-section of the version of the vertical posts (1) indicated in the preceding paragraph, i.e., with one of its sides beveled, and FIG. 13 shows a shelf (5) with its indentations (6) in a shape complementary to the shape of the bevel of the vertical posts (1), such that a dovetail-type joint is established between the vertical posts (1) and the indentations (6) of the shelves (5).

(34) In its simplest version, the furniture shelving would be formed by two ladder-like structures each of which is formed by a pair of vertical posts (1) with their corresponding horizontal slats (3), such as the one depicted in FIGS. 2 and 3, which would be assembled in factory, such that the end user would only have to place the corresponding shelves (5) depicted in FIG. 13 between these two structures and the shelving would be assembled. This embodiment furthermore allows safe transport and occupies minimum space, both from the manufacturing site to the point of sale, and thereafter to the point of installation, given that the two ladder-like structures and the shelves (5) can be arranged such that they occupy parallel planes.

(35) As seen in FIG. 14, if each shelf (5) had the same measurement A at the upper edge and the lower edge of the part of that has to be fitted between the vertical posts (1), in this case the diagonal B would have a measurement greater than the measurement of the separation C between the vertical posts (1), which would result in an interference when assembling the shelf (5). To prevent this interference, chamfering (7) has been envisioned to be made in the respective indentations (6) of the shelf (5), as shown in FIG. 15, such that the measurement of the diagonal b is therefore smaller than the measurement of the separation C between the vertical posts (1), said interference thereby being prevented.
