Detailed description of the invention.
[0011] The present invention includes a tower type central display structure (10) and false lateral volumetric structures (20-20'), of advertising character and various allegorical formats with the displayed products, which are fixedly attached to the central tower structure (10). The central structure (10) is made up of tray modules (a), upright modules (b) that, according to this invention, form closing side walls, components of consecutive corner columns and structural and interlocking elements support of the lateral false structures (20-20'), likewise, the central structure (10) includes connecting pieces (c) in the form of knots to link the tray modules (a) and the upright modules (b).
[0012] Each tray module (a) is formed, from a diecut cardboard blank, whose development is show in this description, in Figures 2 and 3.
[0013] In the assembly position (figures 4 and 6), with each template, a tray is obtained (a) which has a main wall in a quadrilateral shape, with a supportive tubular perimeter flange and corners forming right-angled (12) where the connecting pieces (c) are respectively located. On the main wall of the tray can be assembled a false wall formed by a cardboard sheet (not shown) that strengthen the tray and can hold the appropriate graphic providing it an aesthetic cover. Briefly, since a detailed description is disclosed in patent AR096797 A1, in Figures 2 and 3, it is shown that the central wall in a quadrilateral shape has wings with consecutive parallel folding lines on all four sides to form the sections of the tubular perimeter flange.
[0014] According to the object of the present invention, each upright module (b) includes from a diecut cardboard blank whose development is illustrated in Figure 5A and complementary figures 5B and 5C.
[0015] The template in question has a central portion (1) in the shape of a quadrilateral, in which, two opposite sides constitute lines (2) of folding and linking with respective wings (3) that have parallel consecutive folding lines (4) that form two straight tubes (5). A third side of the template constitutes, likewise, a line (6) of bending and linking with a wing (7a) angularly positioned, preferably at 90°, with the portion (1).
[0016] In the embodiment illustrated in Figures 1, 5A, 5B, 5C, 6 and 7, the false volumetric structures (20-20') correspond to hollow bodies with curved cross section and the wings (7a) have a congruent curved edge.
[0017] It should be noted that the wing in question of the upright module (b) can have other perimeter shapes selected from polygonal, circular and ellipsoidal, regular and irregular, with sides selected from straight, curvilinear and combined between them, in each case congruent with the cross section of the corresponding false lateral volumetric structure.
[0018] In the description that follows, the citations to the false lateral volumetric structures are indicated with the references (20-20') and the wings of the uprights (b) with the references (7a).
[0019] In the uprights (b), the straight tubes (5) have the same cross section as the section of the tubular edges (11) of each tray (a), having a square section in this example.
[0020] As seen in Figure 5A, in the template forming each upright (b), the first two consecutive wall portions of the wings (3), which are delimited by the fold lines (2) and (4), form on one of the edges of the template, extensions (8) whose height is equal to the height of the perimeter tubular edges (11) of each tray module (a), followed by entering (9) with equal height.
[0021] The straight tubes (5) are components of corner column pairs of the central structure (10) and the wing (7a), acts for support and structural reinforcement, as a rib of the corresponding false structure (20-20').
[0022] As emerges from Figures 1 and 6, the central portion (1) of each upright module forms a lateral closing wall between two consecutive superimposed trays (a) of the tower (10) and with reference to Figure 1, it is seen that said wall (1) also closes the portion of the immediate facing face of the attached lateral false structure (20-20').
[0023] The connecting pieces (c) will be briefly described as being the same as those disclosed in patent AR096797 A1. These connector pieces (c) are basically corner knots to structurally link each tray module (a) with the uprights (b), comprising a central part and arms projected in three spatial orthogonal axes. The aforementioned arms of the connector pieces (c) have a square cross section for cooperating fit at the corresponding ends of the tubular edges (11) of the tray modules (a) and straight tubes (5) of the uprights (b).
[0024] The straight tubes (5) of each upright (b) respectively have at one end a defined neckline during the folding of the insole by the entering (9) adjacent the corresponding extension (8). The height of each neckline or entering (9) is equal to the height of the central part of each piece-node (c), with which, in the assembly position (figures 1 and 7) the uncut wall portion, that is, the extensions (8) they cover the mentioned central part of the corresponding piece-knot (c).
[0025] The false lateral structures (20-20 ') are structures that, as previously explained, have an allegorical advertising character with the products that are displayed for sale on the trays (a) of the central structure (10). These false structures (20-20') are preferably made of flexible cardboard, known in the art as "soft cardboard" capable of molding more or less intricate shapes.
[0026] In the embodiment shown in Figures 1 and 7, these false lateral structures (20-20') have a random half-bottle shape with an open flat face facing the corresponding side of the tower (10) and section transverse congruent with the free contour of the wings (7a), (figures 5A, 5B, 5C and 6) which fit into the insert structure for support and structural reinforcement, like ribs, thereof.
[0027] The assembly of the set begins with the folding of the tray modules (a), as illustrated in Figures 2 and 3. For each tray (a), at the ends of two opposite tubular edges (11) the corresponding four-knot arms (c) are inserted. Then, the two remaining opposite wings are folded and fixed in the same way, wrapping the opposite arms of the knots (c), remaining inserts at the ends of these new tubular edges (11), all in accordance with what is shown in Figures 3 and 4.
[0028] Next, the upright modules (b) are assembled, proceeding to the folding of the corresponding templates, as shown in Figures 5B and 5C, with the straight tubes (5) being formed on both sides of the wall (1) and the respective fins (7a) bent at a required angle with said wall (1).
[0029] As can be seen in figure 6, the tray modules (a) thus assembled are linked in a tower shape by fitting the ends of the tubes (5) into the arms of the corresponding corner knots (c). In this position and as shown in figure 7, the lower arms of the nodes (c) of the first lower tray (a) form legs of the structure, likewise, the set of wings (7a) are positioned perpendicular to the walls (1), projecting outward on both sides of the structure (10).
[0030] The assembly of the set (figure 1) is completed with the previous assembly of the false structures (20-20 '), coupling the wings (7a) in said structures, being able to be reinforced said assembly with fixing elements selected from what is known, for example, screws (not shown) that attach fins or other perimeter parts of the false structures with the tubes (5) or with the wall (1) of the uprights (b).
[0031] With reference to Figures 8A, 8B, 9A, 9B, 10A and 10B, other variants are shown, with free-form shapes, non-limiting shapes, for the false lateral structures.
[0032] In the variant shown in Figures 8A and 8B, the false lateral structures refer to halves (30-30 ') of a jar type container, with a curved cross section. Figure 8A shows that the upright modules (b) include wings(7a) with curved edge.
[0033] In the variant shown in Figures 9A and 9B, the false side structures refer to halves (40-40') of a container with a narrow substantially rectangular cross-section. In figure 9A it is shown that the upright modules (b) include rectangular wings (7b) like those shown in figure 5D.
[0034] According to another variant represented schematically in Figures 10A and 10B, the false lateral structures refer to volumes (50-50') in the form of prisms vertical rectangular. Figure 10A shows that the upright modules (b) include rectangular wings (7c) with straight sides as shown in Figure 5E.
- tray modules, each of which is constituted by a cardboard blank having a central portion in the form of a quadrilateral, the corners of which form incoming vertices and the sides of which constitute lines of folding and engagement with respective wings, having first portions with parallel consecutive fold lines capable of forming raised tubular edges, and second portions which together form a wall having the same area as the central portion of the insole and is superimposed therewith, each wing having reciprocal anchoring elements with said central portion of the template,
- straight tubes that make up modules of the modules of each corner column, which have the same cross section as the perimeter tubular edges of each tray module, and
- the invention relates to connector parts in the form of corner nodes, each of which has a central part with arms, projected in three spatial orthogonal directions which fit at the concurrent ends of the tubular edges of each tray module, and the corresponding ends of the tubes that make up the upright modules,
characterized in that the upright modules that constitute the corner columns are made up of templates that form pairs of straight tubes, where each of said templates has a central portion in the shape of a quadrilateral, with lateral closure between two consecutive superimposed trays of the tower, in which two opposite sides constitute folding and bonding lines with respective wings that have parallel consecutive folding lines that form two tubes, and where a third side of the template constitutes in turn a folding and linking line with a lateral lace wing in a given false volumetric cardboard structure, representative of an allegorical body, for support and structural reinforcement of said false structure, where said wing is shaped perimeter copying the cross section of the false volumetric structure.REFERENCES CITED IN THE DESCRIPTION
