FOLDABLE DISPLAY MADE OF CORRUGATED CARDBOARD OR THE LIKE
The invention relates to a display comprising parallel connection panels (5a, 5b, 5c) connected in an articulated manner to first and second parallel wall panels (1, 2), forming a configuration of an articulated parallelogram movable between a working position providing shelves and a folded position over an inner face of the second wall panel (2). Third and fourth wall panels (3, 4) are connected in an articulated manner to opposite longitudinal edges of the second wall panel (2) and are movable between a working position wherein the third and fourth wall panels (3, 4) are substantially perpendicular or inclined in relation to the first and second wall panels (1, 2) and connection panels (5a, 5b, 5c), and a folded position wherein the third and fourth wall panels (3, 4) are substantially parallel and superimposed over an outer face of the second wall panel (2).
The present invention relates to a foldable display made of corrugated cardboard or the like, having a very simple and cost-effective construction and being easy and practical to use, and which in a working position provides a structure capable of standing upright on the ground and provided with one or more shelves for bearing items to be displayed.
BACKGROUND OF THE INVENTIONDocument US 2008/0265726 A1 discloses a foldable display made of a single, bent and glued piece of corrugated cardboard or the like. The foldable display comprises opposite front and rear wall panels, opposite upper and lower panels connected in an articulated manner to said front and rear wall panels, a pair of side panels connected in an articulated manner to the front wall panel, and several shelf panels cut in the front wall panel and connected in an articulated manner to the front and rear wall panels. The front and rear wall panels, the upper and lower panels and said shelf panels form an articulated parallelogram configuration which can be moved between a working position wherein the upper and lower panels and the shelf panels are perpendicular to the front and rear wall panels, and a folded position wherein the front and rear wall panels, the upper and lower panels and the shelf panels are substantially parallel and superimposed. The foldable display includes foldable joint elements keeping the side wall panels coplanar with the front wall panel in the folded position, and retaining means formed by tabs projecting from the rear wall panel and fitting and interlocking in slits of the side wall panels in the working position.
A drawback of the foldable display of the mentioned document US 2008/0265726 A1 is that due to the existence of the mentioned foldable joint elements, the side wall panels cannot be additionally folded to reduce the extension of the display in the folded position once the side wall panels reach a position that is coplanar with the front wall panel.
BRIEF DESCRIPTION OF THE INVENTIONThe present invention helps overcome the preceding and other drawbacks by providing a foldable display made of corrugated cardboard or the like comprising mutually parallel and opposite first and second wall panels, at least two mutually parallel connection panels, each of which has a first transverse edge connected in an articulated manner to said first wall panel and a second transverse edge connected in an articulated manner to said second wall panel, where the first and second wall panels and said at least two connection panels form an articulated parallelogram configuration which can be moved between a working position wherein the connection panels are perpendicular or inclined with respect to the first and second wall panels, and a folded position wherein the first wall panel and the connection panels are substantially parallel to and superimposed over an inner face of the second wall panel. The foldable display further comprises at least one third wall panel having an edge connected in an articulated manner to a first longitudinal edge of the second wall panel, and retaining means retaining said first, second and third wall panels and the at least two connection panels in said working position.
The mentioned third wall panel is foldable around said first longitudinal edge between a working position wherein the third wall panel is substantially perpendicular or inclined with respect to the first and second wall panels, closing a space defined between the first and second wall panels and the connection panels, and a folded position wherein the third wall panel is substantially parallel to and superimposed over an outer face of the second wall panel.
In one embodiment, the foldable display only has the mentioned third wall panel in addition to the first and second wall panels, and in such case the first and second wall panels form side walls, said third wall panel forms a rear wall, and at least one of said connection panels forms a shelf.
In other embodiments, the foldable display includes a fourth wall panel having a first longitudinal edge connected in an articulated manner to a second longitudinal edge of the second wall panel opposite said first longitudinal edge, where the fourth wall panel can be folded around said second longitudinal edge between a working position wherein the fourth wall panel is substantially perpendicular or inclined with respect to the first and second wall panels, closing a space defined between the first and second wall panels and the connection panels, and a folded position wherein the fourth wall panel is substantially parallel to and superimposed over an outer face of the second wall panel together with the third wall panel in the folded position.
In the case of including both third and fourth wall panels in addition to the first and second wall panels, the foldable display of the present invention can have two other embodiments. In one embodiment, the first wall panel forms a rear wall, the second wall panel forms a front wall, the third and fourth wall panels form side walls, and at least one of said connection panels forms a shelf. In another embodiment, the first wall panel forms a front wall, the second wall panel forms a rear wall, the third and fourth wall panels form side walls, and at least one of the connection panels forms a shelf.
Regardless of the embodiment of the foldable display of the present invention, the second wall panel has opposite inner and outer faces, and in the folded position the third and fourth wall panels are folded over the outer face of the second wall panel whereas the articulated parallelogram configuration formed by the first and second wall panels and the connection panels is folded over the inner face of the second wall panel. Therefore, the thickness of the first wall panel and of the connection panels in the folded position is not an obstacle for folding the third and fourth wall panels, and this allows reaching a significantly compact configuration in the folded position.
In one embodiment in which the second wall panel forms a front wall, the second, third and fourth wall panels are integral parts of a first piece of sheet made of corrugated cardboard or the like cut from a previously printed first board of corrugated cardboard or the like. Optionally, the connection panels are also integral parts of said first piece of sheet and are cut in the second wall panel. In such case, the first transverse edge of each of the connection panels is connected to a respective fixing tab by a first weakened line, said fixing tab is fixed to the first wall panel by fixing means, and said second transverse edge of each of the connection panels is connected to the second wall panel by a second weakened line.
Alternatively, one or more of the connection panels are formed by additional pieces of sheet made of corrugated cardboard or the like, where the first transverse edge of each of the connection panels is connected to a first fixing tab by a first weakened line, said first fixing tab is fixed to the first wall panel by fixing means, said second transverse edge of each of the connection panels is connected to a second fixing tab by a second weakened line, and said second fixing tab is fixed to the second wall panel by fixing means. This allows including shelves formed by connection panels with a depth exceeding the vertical distance between shelves.
In one embodiment, the mentioned retaining means comprise a head piece having first retaining elements which fit and are interlocked in second retaining elements formed in the third and fourth wall panels when they are in the working position. This head piece is made up of a second piece of sheet made of corrugated cardboard or the like and can be cut from said previously printed first board of corrugated cardboard or the like together with said first piece of sheet.
In an optional embodiment, the head piece is fixed to the first wall panel by fixing means and the first wall panel has a transverse fold line around which that portion of the first wall panel in which the head piece is fixed can be bent over an outer face of the rest of the first wall panel in the folded position.
In one embodiment in which the first wall panel forms a rear wall, which does not need to be printed, especially if the foldable display includes a printed head piece, the first wall panel is formed by a third piece of sheet made of corrugated cardboard or the like cut from a non-printed second board of corrugated cardboard or the like. This helps reduce the overall cost of the product.
Preferably, in one embodiment in which the third and fourth wall panels are side wall panels, the latter have respective reinforcement panels adhered to their inner faces, said reinforcement panels having hooking elements attached thereto in an articulated manner by weakened lines. These hooking elements are not adhered to the corresponding third and fourth wall panels, such that they can pivot around the mentioned weakened lines. Furthermore, the foldable display includes elastic elements, such as rubber rings, each of which is connected to one of the hooking elements of the reinforcement panel adhered to the third wall panel and to one of the hooking elements of the reinforcement panel adhered to the fourth wall panel, such that the elastic elements pull the third and fourth wall panels towards the working position.
The hooking elements are strategically arranged in positions such that when the foldable display is in the working position, both the hooking elements and the elastic elements are adjacent to a lower face of the connection panels and are concealed by the latter.
Preferably, the third and fourth wall panels have upper edges connected to respective flaps by weakened lines, and said flaps are bent and adhered to an inner face of the respective third and fourth wall panels. In correspondence, the reinforcement panels have cutouts in which the flaps fit.
The reinforcement panels are formed by respective fourth and fifth pieces of sheet made of corrugated cardboard or the like, and given that the reinforcement panels generally do not need to be printed, said fourth and fifth pieces of sheet are cut from said non-printed second board of corrugated cardboard or the like together with the third piece of sheet making up the first wall panel.
