Abstract

The invention relates to a structure which can be folded flat made in a semi-rigid material such as cardboard, having the shape of a cylinder whose directrix is a curvilinear triangle or quadrilateral with its concave face turned outwards. According to the invention, a fold line 7 parallel to the edges 4, 5, 6 is provided in one face 3 which is opposite one of these edges, when the cross section is a triangle, or in two opposite faces in the case of a quadrilateral, so as to allow the said structure to be folded flat.

  Structure connectable to Flat in a semi-rigid material.

  The present invention relates to a folding structure

  flat in a semi-rigid material such as cardboard.

  In many types of businesses, structures are used whose original form attracts the attention of buyers, and which serve as an advertising medium, for

  articles or products for sale in this branch.

  For this purpose, advertising slogans and possibly drawings appear on this structure, which can also serve as a support for the goods being advertised. Such structures serving as advertising media are used in particular in so-called big box stores, for example

  in hypermarkets, but also in smaller pharmacies, notably in pharmacies.

  Their use is ephemeral and, in order to limit as far as possible the costs they involve, they are generally made of a cheap material such as cardboard. As they must have a volume sufficient to attract the attention of buyers or passers-by, it is desirable that they can be folded flat, in order to be delivered to the merchant in a small volume, and they must be able to be put in place.

easily formed by the user.

  The present invention aims to meet these requirements of the technique by proposing, as a new industrial product, a foldable flat structure, in a semi-rigid material, which can be easily placed in volume by users in order to serve as advertising support. To this end, the subject of the invention is a foldable flat structure in a semi-rigid material such as cardboard, having the shape of a cylinder whose directrix is a curvilinear triangle or quadrilateral with concavity facing outwards. , the end of said cylinder being constituted by a cross section -2 on which said structure can rest and the edges of said structure being constituted by fold lines, this structure being characterized in that a fold line parallel to said edges is provided in a face opposite to one of these edges, when the section is a triangle, or in two opposite faces in the case of a quadrilateral, in order to allow the flat folding of said structure, and in that an inner panel, pinched between two faces from an edge of the or each of said faces comprising a fold line has a dimension such that in the folded position of the structure, it is applied against the non-pl contiguous and in the upright position of said structure, it can be applied flat against the face with an adjacent fold line, in order to brace it and lock it in this position, with its free edge pinched between this face and

  the opposite side to which it is attached.

  The movable panel or panels inside the structure between a first position, corresponding to the folding of the structure, and a second position, corresponding to the setting in volume of the structure, ensure by

  therefore maintaining the volume thereof.

  Preferably, the fold line or lines will be made in the middle part of the faces concerned. The section on which said structure rests may be a cross section perpendicular to the edges, in the case of a vertical structure, or arranged obliquely with respect to these structures in the case of an inclined structure. The contiguous faces of the structure are glued flat against each other in the vicinity of the edges, pinching the movable panel between the glued parts

  possibly adjacent to this edge.

  The accompanying drawings illustrate a form of implementation of the invention, in the case of a structure with a section --3 in the shape of a curvilinear triangle. In these drawings: FIG. 1 represents the structure during flat folding; Figure 2 is a view of the same structure, after setting in volume. As we can see, this structure has the shape of a right cylinder, the directrix of which has the shape of a curvilinear triangle. This cylinder consists of three panels 1, 2 and 3, respectively glued flat or stapled along a portion of their internal surface against the adjoining panel, at each of the edges 4, 5 and 6, in order to be kept curved. , the edges serving

of fold lines.

  The panel 3 has, in its middle part, a fold line 7 parallel to the edges of the structure.

  A panel 8, disposed inside the structure, is pinched between the coated parts of the panels 1 and 3, while its opposite edge 9 is free. This panel 8 has, in a plane perpendicular to the edges, a dimension less than the corresponding dimension of the panel 1 and very slightly less than that of the panel 3 comprising

fold line 7.

  As shown in Figure 1, it is thus possible to fold the structure flat, by folding around the line 7, with the panel 8 applied against the internal face

from panel 1.

  When the structure is placed in volume (FIG. 2), it suffices to pivot the panel 8 around the ridge 6, to bring it against the unfolded panel 3, by engaging its free edge 9 between this panel 3 and the adjoining panel 2, so that it ensures the bracing of the panel

  3 and prevents spontaneous folding thereof.

  The structure can thus be delivered flat to the users, who can very easily volume it, position in which it is braced and

locked by panel 8.

  Of course, the invention is not limited to the embodiment which has just been described and, in particular, an embodiment with a section in the form of a quadrilateral, with two opposite panels comprising a fold line and two bracing panels

  corresponding, obviously follows.
