PREFERRED EMBODIMENT OFF THE INVENTION

(5) FIG. 1 represents a view A of a section of the modular shelving (100) according to the present invention (which is shown in FIG. 4). This section shows a bar (10) that is part of the shelving (100), a tray (12) and a fixing plate (16), in addition to some screws (18) that are screwed to the fixing plate (16) allow the fixing plate (16) to be screwed to the tray (12) and to the bar (10) of the shelving (100) increasing the stability of the modular shelving (100).

(6) The set of trays (12) together with the four bars (10) that make up the shelving (100) can be seen in FIG. 4, which also shows the view A of FIG. 1. The shelving (100) is a quadrangular shelving with rectangular shape that includes four bars (10) with holes (which are not seen in the figure) that define the heights of the shelving (100) for placing the trays (12). As can be seen in FIG. 4, the shelving (100) comprises, for example, 5 rectangular trays for this preferred embodiment. In other embodiments, the trays can be square-shaped and the number of trays can vary.

(7) FIG. 2 shows an example of a tray (12). The tray (12) comprises four corners (13) wherein an opening (14) is established. Said openings (14) allow the stacking of two or more trays (13) for storage and transport. Furthermore, each corner (13) comprises a pair of holes (15a, 15b) for attaching the tray to the bars (10) of the shelving (100).

(8) FIGS. 3A, 3B and 3C show a fixing plate (16) according to the present invention, each plate is formed by a first sector (16a) angled at 90 degrees with a second sector (16b) as seen in the FIG. 3A. The first and second sectors (16a, 16b) meet at a plate corner of the plate (20) (i.e., substantially a line of intersection (21) between the first and second sectors (16a, 16b)). The first and second sectors (16a, 16b) define an inner side of the plate as respective surfaces of the first and second sectors (16a, 16b) having an angle of 90 degrees between them, and an outer side of the plate (16) as respective surfaces of the first and second sectors (16a, 16b) having an angle of 270 degrees between them. The first sector (16a) includes first barrel extending from the inner side of the plate (16) defining a third hole (17a). The first barrel is integral with the plate (16) and has a first threaded interior. The second sector (16b) includes a second barrel extending from the inner side of the plate (16) defining a fourth hole (17b). The second barrel is also integral with the plate (16) and has a second threaded interior). The first and second barrels may be substantially cylindrical in shape. The third and fourth holes (17a, 17b) are adapted to match or coincide in diameter with the pair of holes (15a, 15b) of the corner (13) of the tray (12) and at the same time, said pairs of holes (17a, 17b) and (15a, 15b) are adapted to match a pair of holes on the bar (10). In particular, the outer side of the plate (16) is configured to abut one of the corners (13) of the tray (12) such that the third and fourth holes (17a, 17b) of the plate (16) are aligned with a pair of the first holes (15a, 15b) of the tray (12) and a pair of the holes of the bar (10).

(9) Additionally, the plate (16) may include a brace (22) at the inner side of the plate (16) between the first sector (16a) and the second sector (16b), the brace (22) configured to maintain and support the first and second sectors (16a, 16b) at 90 degrees. In particular, the brace (22) is a tetrahedral brace which extends from the plate corner (20) such that a first edge (24) of the tetrahedral brace extends along the plate corner (20), and a second edge (26) of the brace opposite the first edge (24) extends between the first sector (16a) and the second sector (16b) on the inner side of the plate. That is, the first edge (24) is substantially aligned with the plate corner (20), and extends along the line of intersection (21) between the first and second sectors (16a, 16b). The second edge (26) of the brace opposite said first edge (i.e., the edge of the tetrahedral brace which does not share any vertices with the first edge) extends between the first and second sectors (16a, 16b). That is, the second edge (26) has its first endpoint on the first sector (16a), and its second endpoint on the second sector (16b). Preferably, the second edge (26) is a straight edge.

(10) Thus, the pairs of screws (18) shown in FIG. 1 are adapted to screw each plate (16) to said corner of the tray (12) and to the shelving bar through the first and second holes of the plate (17a, 17b), the second pair of holes (15a, 15b) and the first pair of holes of the bar (10). In particular, each pair of screws (18) is adapted to be received through a respective pair of holes of the bar (10), a respective pair of first holes (15a, 15b) of the tray (12), and the third and fourth holes (17a, 17b) of the plate (16). Upon being received in the third and fourth holes (17a, 17b), the screws (18) mate with the first and second threaded interiors of the first and second barrels, respectively, to screw the plate (16) to a corner (13) of the tray (12) and to a respective one of the bars (10).

(11) Screwing the plate (16) to the tray (12) and to the bar (10) of the shelving (100) contributes the attachment of said elements to each other and therefore the assembly of the modular shelving (100) which is shown in FIG. 4. Advantageously, screwing the fixing plate (16) connects the ends of the corner (13) of the tray (12) covering the opening (14). Consequently, the plate increases the stability of the shelving (100).
