Abstract

Self-expanding foldable hollow body for display and self-expanding foldable hollow structural assembly for display. The hollow body comprises an even number of quadrilateral panels (1, 2, 3, 4) jointed together forming an annular band that can be arranged flattened or expanded, the body being closed by a fifth and sixth polygonal panels (5, 6) of number of sides equal to the panels of the band, which have attached hook panels (7, 8) where an elastic traction element (50) that pulls the fifth and sixth panels (5, 6), approximating them, integrating two connection panels (13, 14) attached to edges of a panel of the annular band, adjacent to the panel attached to said fifth and sixth panels (5, 6) and hook panels (9, 10) attached to said panels of connection (13, 14) and which have superimposed on said panels in the form of a hook (7, 8).

In addition, as shown in Fig. 1, the first and second hook connection edges 7a and 8a, and the third and fourth hook connection edges 9a and 10a, are oriented in substantially diagonal directions with respect to the edges of the fifth and sixth panel 5 and 6.

The previously described articulated joint of the first and second hook-shaped panels 7 and 8, by means of said first and second hook connecting edges 7a and 8a, to the internal faces of the fifth and sixth panels 5 and 6, are achieved by means of first and second fixing panels 11 and 12 fixed by adhesive C1 to said internal faces of the fifth and sixth panels 5 and 6, as can be seen in Figs. 2 and 3. Said first and second fixing panels 11 and 12 are each joined, by means of joints, to the respective fifth or sixth panel 5 or 6, and to the respective first or second hook-shaped panel 7 or 8, by the respective connecting edges 11a or 12a, and the respective first or second hook connection edges 7a or 8a.

In order to achieve a simple and economical production, all the parts that make up said self-expanding hollow body, with the exception of elastic tensile means 50, are integrated into a single piece of sheet material 30, so that after said cutting sheet material 30, simple bending and gluing operations shown in Figs. 2 to 8, allow to obtain said hollow body.

Since the base material is a sheet material 30, but the initial geometry of the hollow body is an annular band formed by the articulated joint of the first panel 1, joined to one side of the second panel 2 by said first connecting edge 1a, the second panel 2 attached to one side of the third panel 3 by said second connection edge 2a, the third panel 3 attached to one side of the fourth panel 4 by said third connection edge 3a and the fourth panel 4 attached to one side of the first panel 1 by said fourth connecting edge 4a, it is provided that any one of said articulated connecting edges 1a, 2a, 3a or 4a is obtained by fixing, by means of adhesive C2, of a fixing flap 19, fixed in the manner shown in Fig. 3 and 4, thus allowing the obtaining of said annular band from said sheet material 30.

According to the first embodiment described in Fig. 1, said fixing flap 19 is between the third and fourth panels 3 and 4.

Both in Fig. 1 and in Fig. 9 it can be seen that in said piece of sheet material 30, first and second limiting panels 15, 16 are articulated jointly connected by respective connecting edges 15a, 16a to opposite transverse edges to said third and fourth connecting edges 3a, 4a of the fourth panel 4, which is adjacent to the first panel 1, said first and second limiting panels 15, 16 having inclined edges that are provided to be connected to corresponding inclined edges of second and third limiting panels 17, 18 articulated jointly by respective connecting edges 17a, 18a to opposite edges transverse to said second and third connecting edges 2a, 3a of the third panel 3, which is adjacent to the second panel 2, so that the first and third limiting panels 15, 17 and the second and fourth limiting panels 16, 18 reach a coplanar position limiting the expansion of the body h The socket 40 in the expanded position and in particular determining a seating plane for faces 5 and 6 drawn in approximation by the elastic tensile element 50 (Figs. 5 and 8).
