Description

SELF-EXPANSIBLE FOLDING SIDE SUPPORT FOR EXHIBITOR

Technical field

The present invention concerns a self-expanding folding side stand for exhibitor, comprising a structure formed by several panels of a sheet material, such as strong paper, thin cardboard, or plastic, fixed to a surface of an exhibitor to support or stabilize the display erect when in an expanded position.

Background of the invention

US-A-7367S39 discloses a lateral support for an exhibitor, comprising a structure made of several panels of a sheet material, with a fixing panel fixed to a rear surface of an exhibitor and two support panels articulated together to the fixing panel along respective vertical fold lines. The support panels may be (folded outwardly by said fold lines from an expanded position in which the support panels are substantially perpendicular to the fixing panel and the display surface, to a folded position, in which the panels of support are coplanar with the fixing panel and superimposed on the surface of the display stand In the expanded position, lower edges of the support panels collaborate with a lower edge of the display to provide a support base capable of supporting the display in a vertical or slightly tilted backward position.The structure includes stopper flaps connected to the fixing panel along respective horizontal fold lines, which can be folded between an active position, in which the stopper fins are raised and in contact with the support panels when they are in 1 .. expanded position, and a position inactive, in which the stop fins are coplanar with the fixing panel and with the stop panels when they are in the folded position.

Elastic elements connected to the support panels and the stop fins push the structure towards the expanded position. The structure can be moved from the expanded position to the folded position by applying an external pressure against the support panels to fold them out against the thrust of the elastic elements. The fixing panel and the support panels include horizontal fold lines aligned with corresponding horizontal fold lines of the display that allow the assembly to be zigzag from the folded position to a compact folded position.

A drawback of the lateral support of said patent US-A-7367539 is that the fins of

stop and elastic elements are exposed to view when the exhibitor in a situation of

service with the structure in the expanded position, providing an unsightly appearance to the

exhibitor. In addition, the side support structure provides few large surfaces and

cleared suitable as a support for graphic and / or textual information. On the other hand, the operation of

moving from the expanded position to the folded position can be difficult and cumbersome since

Two support panels should be folded out in opposite directions against the thrust of

the elastic elements.

International patent application WO 20071112538 describes an inclined structure

backwards to support an exhibitor. The structure comprises a front panel, a rear panel,

S

and two side panels that have vertical edges articulately connected to respective

vertical edges of the front and rear panels. The side panels are foldable inwards

through respective vertical fold lines, so that the structure can be

folded from an expanded three-dimensional position, in which the side panels are

substantially perpendicular to the front and rear panels and lower edges of the

10

four panels provide a support base, and a flat folded position in which the four;

panels are overlapping. A butt fin is articulated connected to the front panel by

a horizontal fold line and an elastic element is connected to the rear panel and the fin of

stop to move the stop flap from an inactive position superimposed on the front panel, when:

The structure is in the folded position. to an active position substantially perpendicular to the

fifteen

four panels, when the structure is in the expanded position. The tension of the elastic element:

is greater when the stopper fin is in the inactive position than when it is in the active position.

From the butt fin protrudes a tongue that is inserted into a slit in the rear panel when the

The stopper reaches the active position. The panels of the structure hide the butt fin and the

elastic element in the expanded position. and offer a surface that could be used as

twenty

support of graphic and / or textual information.

However, a drawback of the structure of the aforementioned international patent application

WO 2007/112538 is that to move the structure from the expanded position to the folded position

it is necessary to release the mentioned tongue of the slit, and this causes the tension of the element

elastic move the stopper fin to a new inactive position opposite the inactive position

25

initial. The tension of the elastic element when the retention alert is in this new position

inactive is less than the voltage in the active position and much less than the voltage in the position

inactive initial, and this makes it impossible for the structure to automatically expand again by the

elastic element tension. Thus, the structure is only self-expanding once only starting from

an initial folded position with the stopper flap in the initial inactive position, and the structure does not

30

it can be moved from the expanded position to the folded position by an external pressure exerted

on the panels moving at the same time> the stopper flap to the initial inactive position in which the

Stress of the elastic element is greater than the tension in the active position. The fact that

side panels are connected to both the front panel and the rear panel prevents applying to this

display stand for the solution described in the aforementioned patent US-A-7367539. since the panels

35

laterals cannot be folded towards fu era to move from the expanded position to the position

p legacy increasing the tension of the elastic element.

Exhibition of the invention

The present invention contributes to overcoming the foregoing and other inconveniences by providing a self-expanding folding side stand for exhibitor, comprising a structure formed by several panels of a sheet material connected to each other by fold lines, including at least one fixing panel fixed to a surface of an exhibitor and one or more support panels. The mentioned structure is foldable by said fold lines between an expanded three-dimensional position, in which at least one lower edge of said one or more support panels provides a support base in contact with a horizontal support surface J, generally in cooperation with a lower edge of the display, and a flat folded position, in which said various panels of the structure are substantially flat and superimposed on said surface of the

exhibitor. The lateral support also includes an elastic element connected to the structure to push the structure towards said expanded position. Said elastic element has a higher tension level when the structure is in said folded position than when it is in the: expanded position.

The lateral support also includes at least one limiting configuration made of a sheet material and articulated connected to the structure by a fold line. This limiting configuration is movable between a flat idle position. superimposed on the various panels of the structure when they are in the folded position. and an active position. in which the limiting configuration limits the expansion of the structure in the expanded position. Preferably, the limiting configuration is linked to the structure and / or the elastic element so that the limiting configuration is moved from said inactive position to said active position by a part of the structure and / or by the elastic element during movement of the structure from the folded position to the expanded position.

The one or more support panels are configured so that they hide the elastic element and the limiting configuration when they are in the expanded position, and have a clear outer surface that can be used as a graphic or textual information support. In addition, the structure is configured so that it can be moved from the expanded position to the folded position by an external pressure exerted on the support panels against the thrust of the elastic element at the same time that the limiting configuration is moved or dragged from the position active to the inactive position by a part of the structure and / or by the elastic element during its movement from the expanded position to the folded position. The aforementioned external pressure is generally applied in an appropriate direction to crush the structure against the surface of the display to change from the expanded position to the folded position.

The particular configuration of the side support structure of the present invention means that the various panels that form the structure are made of a single piece or several pieces joined together of a relatively thin sheet material, such as, for example, sheet of strong paper, thin cardboard sheet, or plastic sheet, of an appropriate thickness to be printed directly on a conventional printing machine, contrary to what happens with many prior art media, which require to be made of thick cardboard or corrugated cardboard that cannot be printed directly.

The lateral support of the present invention is especially indicated for supporting an exhibitor of the type formed by a single plate arranged in a vertical position or slightly tilted back, with a front surface showing graphic and / or textual infannation, and a rear surface to which the mentioned fixing panel of the lateral support structure is attached, for example by adhesive. With the lateral support of the present invention, the rear face of the display and / or the support panels of the lateral support can be used as support for additional graphic and / or textual information. In this way, the exhibitors equipped with the lateral support of the present invention can be placed in places where they can be seen from both sides.

Alternatively, the lateral support of the present invention can be used to provide additional stability to self-sustaining displays of the type provided, by. example, of several panels facing each other and connected by their lateral edges forming a vertical column of circular, elliptical or polygonal cross-section. In these exhibitors only the outer surfaces of the panels that form it are visible, which are all used to support graphic and / or textual information. The fixing panel of the side support structure is attached, for example by adhesive, to one of said external surfaces of the display and the support panels of the side support structure can be printed, for example, by graphic information and / or textual complement of the graphic and / or textual information shown on the display panels.

According to one embodiment, the side support structure comprises a single support panel of generally triangular shape, which, when in the flat folded position, has a pair of rectilinear side edges and a curved bottom edge. In the expanded position, this single support panel adopts a partially conical three-dimensional configuration, with said S 'two side edges facing said display surface and with said lower edge providing said support base.

In another embodiment, the side support structure comprises two lateral support panels generally triangular in shape connected to each other by a central fold line, which, when in the flat folded position, have respective opposite side edges and respective ones contiguous bottom edges. When the structure is in the expanded position, the two lateral support panels adopt a partially pyramidal three-dimensional configuration, with said opposite lateral edges facing the surface of the display and with said lower edges providing the support base.

According to yet another embodiment, the structure comprises two lateral support panels of generally triangular shape connected by respective fold lines to opposite lateral edges of a central support panel of generally quadrilateral shape, ie rectangular or trapezoidal, although also It can be triangular with the base at the lower or upper end. When the structure is in the flat folded position, all said support panels are substantially coplanar, and the two lateral support panels have respective opposite side edges and respective bottom edges adjacent to a lower edge of the central support panel. When the structure is in the expanded position, the support panels adopt a generally three-dimensional polyhedral configuration with said lateral edges of the two lateral support panels facing said surface of the display and said lower edges of the two lateral support panels and of the central support panel providing the support base.

In any of the previously described embodiments, the fixing panel, the limiting configuration and the elastic element, which are always hidden by the panels of: support in the expanded position, can adopt a variety of fonts and arrangements providing different operating modes, some of which will be described in detail below by way of example. Advantageously, the support panels, the fixing panel, the limiting configuration, as well as other auxiliary panels that the structure may optionally include, are obtained by die-cutting as a single piece of sheet material, although: alternatively they can always be obtained as two or more pieces of adhesive bonded sheet material. The fold lines are weakened lines obtained, together with other optional fold lines or cuts, in the same die-cutting process. The fold lines are generally rectilinear to provide rectilinear edges and flat panels, although alternatively some fold lines can be curved to obtain arched edges and combined panels.

It is usual that the plate or panels of the display have a horizontal fold line through which the panel can be folded to a compact position, in which case, the one or more panels of the side support structure of the present invention comprise respective transverse fold lines in alignment with said horizontal fold line of the display to allow folding the side support together with the display plate or panels to the compact folded position.

The present invention provides for the use of a retention panel in combination with any of the embodiments of the lateral support to retain the structure in the folded position with little effort. This retention panel is articulated to the structure or to the surface of the display protruding from the lower edge of the one or more support panels when the structure is in the folded position, and can be folded by a fold line and superimposed on the structure. or to the exhibitor when the structure is in the folded position. Thus, the pushing force produced by the tension of the elastic element is distributed over the relatively large surface of the retention panel and the structure can be retained in the folded position by exerting a relatively low pressure on the retention panel. The retention panel is useful to help retain the structure of the lateral support in the folded position inside an envelope or other similar container. The retention panel is configured and dimensioned so that it is hidden by the structure of the lateral support when it is in the expanded position and in an operating position supporting the stand upright on a support surface, since in such a situation the retention panel does not protrude from the bottom edges of the support panels.

Detailed description of some embodiments

Referring firstly to Figs. 1 to 4, by the numerical reference 10, a structure of a self-expanding folding lateral support in accordance with an embodiment of the present invention is generally designated. Said structure 10 is formed by several panels of a sheet material, such as for example strong paper sheet, thin cardboard sheet, or sheet

plastic, articulated connected to each other by fold lines. Fig. 2 shows a flat die cut piece that includes all the panels and fins necessary to form the structure 10.

In the example of Figs. 1 to 4, the structure 10 comprises first and second support panels 2, 3 generally triangular in shape, connected to each other by a fold line 8 along respective adjacent edges. These first and second support panels 2, 3 have respective first and second opposite side edges 2a, 3a and respective adjacent lower edges 2b, 3b, as can be seen when they are in an extended position shown in Fig. 2. A fixing panel 7 is articulated connected to the first lateral edge 2a of the first support panel 2, and a limiting configuration in the face of a stopper flap 6 is connected by a fold line 11 to an opposite edge of the fixing panel 7. The second edge: side13a of the second side panel 3 is articulatedly connected to a reinforcement flange 23. In the stopper flap 6 and in the reinforcement flange 23, respective first and second are connected. clamping configurations 12 ~ 13.

As shown in Figs. 3 AND 4, said fixing panel 7 is fixed to a rear surface of a display 50 by means of an adhesive 24 applied to the outer face of the fixing panel 7 (and shown symbolically by a striped area in Fig. 2), of so that the first lateral edge 2a of the first support panel 2 is in a phylo position in relation to the surface of the display 50, while the second lateral edge 3a of the second support panel 3. is movable. The reinforcing flange 23 is folded along the fold line corresponding to the second lateral edge 3a and attached to an inner face of the second support panel 3 by means of an adhesive 2 ~ applied to the inner face of the reinforcing flange 23 (and shown symbolically by an area: dotted in Fig. 2). Once the structure 10 is assembled, the first fastening configuration 12 is arranged relatively close to the first fixed side edge 2a with respect to the surface of the display 50, and the second fastening configuration 13 is arranged relatively close to the second movable side edge 3a.

An elastic element 5 in the shape of an elastic cord, and more preferably in the shape of an elastic ring, is engaged in said first and second fastening configurations 12, 13 to attract the second movable side edge 3a of the second support panel 3 towards the first lateral edge 2a sliding on the surface of the display 50 to move the structure 10 from the folded position to an expanded position (Figs. 1 and 3), in which the first and second support panels 2, 3 adopt a configuration three-dimensional partially pyramidal, with the first and second lateral edges 2a, 3a opposite facing the rear surface of the display 50 and the lower edges 2b, 3b providing a support base for holding the stand upright, generally in cooperation with a lower edge of the display SW.

The stopper flap 6 can be folded along the fold line 11 between an inactive position, substantially coplanar with the structure panels 10 in the folded position, and an active position, and said elastic element 5 is engaged in the first groove configuration 12 such that it lifts the stop fin 6 from the inactive position to the active position while pushing the structure 10 towards the expanded position. The stopper flap 6 has an edge configured to do with the second side panel 3 when said stopper fin 6 is in the active position to limit the expansion of the structure 10 in the expanded position shown in Fig. 3. The two Support panels 2, 3 are configured to hide the fixing panel 7, the elastic element 5 and the imitation configuration 6 when they are in the expanded position. and they have an exterior surface that can be used as a graphic or textual information support.

The structure 10 is configured to be moved from the expanded position to the folded position against the thrust of the elastic element 5 by an external pressure (indicated symbolically: by an arrow P in the figures) exerted on the support panels 2, 3, Y the stop fin 6 is moved from the active position to the inactive position by the elastic element 5 during its movement from the expanded position to the folded position, as shown in Fig. 4, while: the second edge 3a of the second panel of support 3 moves away from the first edge 2a of the first support panel 2 sliding on the surface of the display 50 and the center fold line 8 approaches the rear surface of the display 50. In the flat folded position, the various panels of the structure 10 are substantially flat and superimposed on the rear surface of the display 50. When the structure 10 is in the folded position, the elastic element 5 has a level The voltage is higher than when it is in the expanded position. Therefore, when the pressure P is removed, the structure 10 automatically expands again to the expanded position due to the tension of the elastic element 5.

In Figs. 5 to 8 another embodiment of the lateral support of the present invention is shown, which is analogous to the one described above in relation to Figs. 1 to 4 except that here the structure 10 comprises a single support panel I instead of the two support panels 2;

3. As best seen in Fig. 6, this single support panel 1 is generally triangular in shape and has first and second lateral edges the, lb. and a lower edge le, which, when in the folded position flat, it is preferably curved. When the structure 10 is in the expanded position shown in Fig. 5, the only support panel I adopts a partially conical three-dimensional configuration, with said first and second lateral edges the, lb facing the rear surface of the display 50 and said edge bottom Ic providing a support base, generally in cooperation with a lower edge of the display 50. The structure 10 of the embodiment shown in Figs. 5 to 8 includes a stopper flap 6, a fixing panel 7, a reinforcement flange 23 and an elastic element 5, the configuration and functionality of which is analogous to that described above in relation to Figs. 1 to 4, so your detailed description will be omitted.

The elastic element 5, which is in the form of an elastic cord, or more preferably in the form of an elastic cord, is arranged for <l alr <ler the second movable edge later <ll lb movable of the single support panel 1 towards the first lateral edge the f!, jo sliding on the surface of the display 50 to move from the folded position to the expanded position while the stop fin 6 is moved from the inactive position to the active position limiting the expansion of the lOen structure the expanded position. The structure 10 can be moved from the expanded position (Figs. SY 7) to the folded position (fig. 8) against the thrust of the elastic element 5 by an external pressure (indicated symbolically by an arrow P in the figures) exerted on the single support panel 1 while the stop fin 6 is automatically moved from the active position to the inactive position.

In Figs. 9 to 12 another embodiment of the lateral support of the present invention is shown, which comprises a structure 10 with first and second similar triangular support panels 2, 3 those shown in Figs. I to 4, connected by a central fold line 8 and with: respective first and second side edges 2a, 3a opposite and respective adjacent bottom edges 2b, 3b, although the internal mechanism is different, as will be described below. In the expanded position (Figs. T and t) these first and second support panels 2, 3 adopt one: partially pyramidal three-dimensional configuration, with the first and second lateral edges 2a, 3a opposite facing the rear surface of the display SO and the edges bottoms 2b, 3b providing a support base for supporting the upright display, generally in cooperation with a lower edge of the display 50.

As best seen in Fig. 9, the structure 10 comprises a fixing panel 7 which has opposite side edges connected by fold lines 7a to respective folding panels 9, each of which is divided into portions. inner and outer 9a, 9b by an intermediate fold line 20. The outer portion 9b of one of these two folding panels ~ 9 has an edge articulably connected to the second side edge 3a of the second support panel 3, while the outer portion 9b of the other of the folding panels 9 is configured to be superimposed on a reinforcement flange 26 articulatedly connected to the first lateral edge 2a of the first support panel 2 when the structure 10 is folded and assembled (Fig. 10). In the outer portions 9b of the folding panels 9, respective first and second fastening configurations 12, 13 are attached, and in said reinforcement flange 26 an additional fastening configuration 13a is connected to which the second fastening configuration 13 overlaps when the Structure 10 is assembled (Figs. 10, 1I and 12). A limiting configuration in the form of a stop fin 6 is connected by a fold line 14 to a lower edge of the fixing panel 7.

The measuring panel 7 is fixed to a rear surface of a display 50 by means of an adhesive 24 (symbolically shown by a striped area in Fig. 10) applied to the outer face of the fixing panel 7, and the elastic element 5, the which is in the form of an elastic cord

or an elastic ring. it is connected on one side to the flow configuration formed in the outer portion 9b of one of the folding panels 9 and on the other to the superimposed clamping configurations 13, 13a formed in the outer portion 9b of the other of the folding panels 9 and in the refractive flange 26, respectively, resulting in ql1e the outer portions 9b of both folding panels are articulated connected to the respective lateral edges 2 ~ 3a of the two support panels 2, 3. The tension of the elastic element 5 attracts the opposite first and second lateral edges 2a, 3a of the first and second lateral support panels 2, 3 towards each other sliding on the surface of the display stand SO while the folding panels 9 fold down their respective intermediate fold lines 20 to pass from the folded position (Fig. 12) to the expanded position (Fig. 1 \).

A portion of the elastic element S is passed under the stop fin 6 so that the stop fin 6 is lifted by the elastic element from an inactive position to an active position when the structure 10 passes from the folded position to the position expanded. The stop fin 6 is provided with opposite side edges 6a configured to make counting said inner portions 9a of the folding panels 9 when said stop fin 6 is in the active position and the structure 10 is in the expanded position, thus limiting the expansion of the structure 10 in the expanded position (Fig. 11). The structure 10 can be moved from the expanded position (Fig. 11) to the folded position (Fig. 12) against the thrust of the elastic element 5 by an external pressure (indicated symbolically by an arrow P in the figures) exerted on the first and second support panels 2, 3, whereby the lateral edges 2a, 3a of the first and second support panels 2, 3 move away from each other sliding on the surface of the display 50 and the center fold line 8 Approaches the rear surface of the display 50 while the folding panels 9 are deployed and the stop fin 6 is automatically moved from the active position to the inactive position. When the structure 10 is in the folded position, the elastic element 5 has a higher tension level than when it is in the expanded position. Therefore, when the pressure P is removed, the structure 10 automatically expands again to the expanded position due to the tension of the elastic element 5.

In Figs. 13 to 16 shows another embodiment of the lateral support of the present invention analogous to that described above in relation to Figs. 9 to 12 except that here the stop fin 6 and the reinforcement flange 26 are suppressed (compare Fig. 13 with Fig. 9), and the outer portions 9b of the folding panels 9 are configured to be superimposed and adhered to corresponding portions of the inner faces of the first and second support panels 2, 3 by means of an adhesive 25 applied to the inner face of the folding panels (and shown symbolically by dotted areas in Fig. 13). The first and second fastening configurations 12, 13 have been replaced by first fastening configurations 12a, 12b and second configurations 13a, 13b formed in the inner portions 9a of the folding panels close to the intentional fold lines 20.

Thus, as shown in Fig. 14, the elastic element 5 pushes the structure 10 towards the

expanded position in a manner analogous to that described above in relation to Figs. 9 a

12, except that here the limiting configuration is provided by the inner portions

9a of the folding panels () in cooperation with the contact of the first and second side edges

the, lb of the first and second lateral edges 2a, 3a of the first and second support panels

sides 2, 3 with the t.rase surface of the SO display to limit the expansion of the structure 10 in

the expanded position. The structure 10 can be moved from the expanded position (Fig. 15) to the

folded position (Fig. 16) against the thrust of the elastic element 5 by an external pressure (indicated

S

symbolically by means of an arrow P in the figures) exerted on the first and second panels of

support 2, 3. When the structure 10 is in the folded position, the elastic element 5 has a level

of higher tension than when in the expanded position. Therefore, when the

pressure P is removed, structure 10 automatically expands back to the expanded position

due to the tension of the elastic element S.

Fig. 17 shows an alternative embodiment in which the structure 10 comprises a single

Figs. 19 and 20 illustrate another embodiment of the lateral support of the present invention, in the

that the structure comprises first and second lateral support panels 2, 3 of form

generally triangular, which are connected by respective fold lines 830 8b ~

opposite side edges of a central support panel 4 generally quadrilateral, and

twenty

more specifically rectangular in the embodiment shown. The central support panel 4 has some:

opposite upper and lower edges 4a, 4b, and the first and second side support panels 2, 3

they have respective first and second opposite edges 2a, 3a opposite and respective edges

lower 2b, 3b adjacent to the lower edge 4b of the central support panel 4 when the structure 10

They are in a flat folded position. When structure 10 is in the expanded position (Figs. 19

25

And 20), the first and second side support panels 2, 3 and the central support panel 4 adopt

a generally polyhedral configuration, with the first and second lateral edges 2a, 38 of the

first and second side support panels 2, 3 And the top edge of the panel is supported 4a center

4 facing the rear surface of the exhibitor SO and the lower edges 2b, 3b of the first and

second side support panels 2, 3 And said lower edge 4b of the central support panel 4

providing a support base for the SO display, generally in cooperation with a border

bottom of the eXPlsitor SO.

As shown in Fig. 20, the structure 10 provided with the first and second panels of

lateral support 2, 3 and the central support panel 4 includes an internal mechanism analogous to that described

above in relation to Figs. 9 to 12, but with the butt fin 6 widened in a proportion

35

equivalent to the width of the central support panel 4. One skilled in the art will understand that the

structure 10 provided with the first and second side support panels 2, 3 and the support panel

Center 4 could also work alternately with an internal amylogo mechanism described above.

fifteen

above in relation to Figs. 13 to 16 with appropriate adaptations. It will also be understood that alternatively the central support panel 4 could be trapezoidal or even triangular in shape, either with the vertex at the top or bottom.

In Figs. 21 and 22 another embodiment of the lateral support of the present invention is shown, which is analogous to that described above in relation to Figs. 19 and 20, with the difference that here the opposite upper and lower edges 4a 4b of the center support panel J 4 are significantly longer than the other two opposite edges that form the fold lines 8a, 8b. As shown in Fig. 22, the internal mechanism is analogous to that described in relation to Figs. 9 to 12, with the difference that the stop fin 6 is widened in a proportion equivalent to the width of the central support panel 4. In addition, a stiffening flange 27 is connected: articulately to the lower edge 4b of the central support panel 4 and bent inwardly at an angle with the central support panel 4 in order to stiffen the lower edge 4b thereof. Additionally, a similar flange (not shown) could be articulatedly connected to the edge: upper 4a of the central support panel 4, bent inward and joined. for example by adhesive, to the rear surface of the display 50.

With reference now to Figs. 23-26 another embodiment of the self-expanding folding side support of the present invention applied to support an display 50 is described. The side support comprises a structure 10 having first and second support panels 2, 3 of generally triangular shape, connected the one to the other by a central fold line 8 along respective respective adjacent edges. These first and second support panels 2, 3 have one respective first and second side edges 2a, 3a opposite and respective adjacent edges ~ 2b, 3b, as can be seen when they are in an extended position shown in Fig;

24. Each of the first and second side support panels 2, 3 is divided into two portions by a panel fold line 2c, 3c located between the corresponding side edge 2a, 3a and the center fold line 8 and extending from the corresponding lower edge 2b, 3b to a vertex opposite it.

As best seen in Fig. 24, a pair of fixing panels 7 are articulably connected to the first side edge 2a of the first support panel 2 and the second edge 3a of the second support panel 3, respectively, and a pair of stiffening tabs 15 are connected by respective fold lines to the lower edges 2a, 3a of the first and second side support panels 2, 3 respectively. Each of these stiffening tabs 15 is divided into two portions by a fold line ISa extending from the end of the corresponding panel sheet line 2c, 3c to a free edge of the stiffening flange 15 opposite the corresponding edge lower 2b, 3b. In the stiffening flange 15, first and second clamping configurations 12, 13 are formed. When the structure 10 is folded and assembled to the display 50 as shown in Figs. 25 and 26, the two fixing panels 7 are fixed to a rear surface of the display 50 by means of an adhesive 24 applied to the outer face

of each fixing panel 7 (and shown symbolically by a striped area in Fig. 2), of

handle that the first and second lateral edges 2a. 3rd opposites of the first and second panels of

lateral supports 2, 3 remain in fixed positions in relation to the surface of the display 50 in

under fixing panels 7 attached to it.

5

An elastic element 5 in the shape of an elastic cord, or preferably a ring

elastic, is connected to said first and second clamping configurations 12, 13 rounds in

stiffening tabs 15 to push the structure 10 into an expanded position (Figs. 23

and 25) in which the first and second lateral support panels 2, 3 adopt a configuration

three-dimensional partially pyramidal, with the first and second lateral edges 2a, 3a opposite

10

facing the rear surface of the exhibitor SO and the lower edges 2b, 3b providing a ~

support base to hold the stand upright, usually in cooperation with an edge

bottom of the exhibitor SO. The limit of the expansion of the structure 10 in the expanded position lo

provide here the stiffening tabs 1 S, when the two portions of each tab d ~

stiffening 15 are mutually coplanar, which occurs at the same time as the two portions

1 S

of each of the first and second side support panels 2, 3 are also mutually ~

coplanar. The plane formed by the two portions of each stiffening flange 15 forms a.

angle with the plane formed by the two portions of the corresponding first or second panel d ~

adjacent side support 2, 3, which prevents the first and second side support panels 2.

3 fold further inwards by the respective panel fold lines 2c, 3c.

twenty

The structure 10 is configured so that it can be moved from the position

expanded (Fig. 25) to the folded position (Fig. 26) against the thrust of the elastic element 5 mediant ~

an external pressure (indicated symbolically by an arrow P in the figures) exerted on

the first and second support panels 2, 3 in cooperation with a slight inward pressure

on the 1 S stiffening tabs, whereby the 1 S stiffening tabs are blanched

25

inside by their respective fold lines 15a and the first and second support panels 2, 3 are

fold outward by their respective panel fold lines 2c, 3c so that they move away

each other while the center fold line 8 approaches the rear surface of the

display until reaching a folded position in which the panels that form the structure 10 are

substantially coplanar and attached to the rear surface of the SO display. When the structure

30

10 is in the folded position, the elastic element S has a higher tension level than

when in the expanded position. Therefore, when the pressure P is removed, the structure

10O automatically expands back to the expanded position due to the tension of the

elastic element 5.

It will be understood that the stiffening eyelash system 15 described above is likewise

35

applied cable to a lateral support comprising a structure 10 composed of first and second

lateral support panels 2, 3 and a central support panel 4, as described above in

relationship with Figs. 19 to 22.

In Figs. 27 to 30 shows another embodiment provided with a structure 10 comprising a single support panel 1 similar to that described above in relation to Figs. 5 to 8 but in combination with limiting configurations provided by stiffening tabs 15 analogous to those described above in relation to Figs. 23 to 26. Here, as best shown in Fig. 28, the only support panel 1 has a generally triangular phonoa, with a first and second lateral edges, and a curved lower edge. The single support panel 1 is divided into three portions by a pair of panel fold lines Id extending from said curved bottom edge to an opposite vertex. A pair of fixing panels 7 are articulatedly connected to the first and second lateral edges la, lb of the single support panel 1, respectively, and a pair of stiffening tabs 15 are connected by respective lines: fold to the lower edge Ic of the single support panel I extending to the side and side of the panel fold lines Id, respectively, and leaving a central portion of the lower edge Ic free.

Each of these stiffening tabs 15 is divided into two portions by a line of: fold ISa which extends from the end of the corresponding panel fold line Id to a free edge of the stiffening flange 15 opposite the lower edge lc . In. The stiffening flanges 15 are fitted with first and second fastening configurations 12, 13. When the structure 10 is folded and assembled to the display 50 as shown in Figs. 29 and 30, the two fixing panels 7 are fixed to a rear surface of the display 50 by means of an adhesive 24 applied to the outer face of each fixing panel 7 (and shown symbolically by a striped area in Fig. 28), so that the first and second side edges, the opposite lb of the single support panel l remain in fixed positions in relation to the surface of the display 50 by virtue of the fixing panels 7 adhered thereto.

When the structure 10 is in the expanded position shown in Fig. 29, the only support panel I adopts a partially conical three-dimensional configuration, with said first and second lateral edges the, lb facing the rear surface of the display 50 and said lower edge Ic providing a support base, generally in cooperation with a lower edge of the display 50. In this expanded position, portions of the single support panel I adjacent to each of the panel fold lines Id are substantially coplanar and the two portions of each stiffening flange 15 are coplanar in another plane that forms an angle with the plane formed by the two portions of the only adjacent support panel I, thus limiting the expansion of the display in the expanded position. To move the structure 10 from the expanded position (Fig. 29) to the folded position (Fig. 30), an external pressure P will be applied analogously to that described above in relation to Figs. 24 to 27.

Referring now to Figs. 31 and 32, there is shown a self-expanding folding lateral support according to the embodiment shown in Figs. 24 to 26 applied to a display 50 of the type formed by a single plate that must be supported by the lateral support in a vertical position or slightly tilted backwards. The structure 10 according to the aforementioned embodiment has a pair of fixing panels attached, for example by adhesive, to a rear surface of the display

50. The lateral support further includes a retaining panel 21 protruding from the lower edges 2b, 3b of the first and second lateral support panels 2, 3 Y of a lower edge of the display SO when the structure 10 is in the position. folded Said retention panel 21 is articulatedly connected to the fastening panels 7 of the structure 10 by a fold line 22, so that it can be folded by a fold line 22 and superimposed on the structure 10 when it is in the folded position, as shown in Fig. 31, to help retain the structure 10 in the folded position by means of a slight pressure P applied on the retension panel 21. This slight pressure P is the one that can, for example, exert , the walls of an envelope within which the exhibitor assembly 50 is housed with the lateral support in the folded position and the panel: folded retention on it.

As shown in Fig. 32, when the slight pressure P is removed from the retention panel 21, the tension of the elastic element 5 expands the structure 10 towards the expanded position and the retention panel 21 is bent outwards by the fold line 22 releasing the structure 10. The retention panel 21 is conveniently configured to be hidden by the structure 10 when it is in the expanded position and in a service situation by holding the display 50 in an upright position on a support surface. It is obvious that the retaining panel 21 can be used in combination with any of the embodiments of the lateral support described above, either including a single support panel 1, two triangular support panels 2, 3 or two support panels 2, 3 And a central support panel 4, the retention panel 21 protruding in each case from the lower edge lc of the single support panel 1 and the lower edge of the display 50, of the lower edges 2b, 3b of the support panels 2, 3 And of the lower edge of the display stand SO, or of the lower edges 2b, 3b of the support panels 2, 3 and / or of the lower edge 4b. of the central support panel 4 and of the lower edge of the display 50, respectively, when the structure 10 is in the folded position. Alternatively, the retaining panel 21 may have a fixing flange (not shown) connected thereto by the fold line 22 and attached, for example by adhesive, directly to the rear surface of the display 50.

In Figs. 33 to 38 shows another embodiment of the lateral support of the present invention, which comprises a structure 10 with first and second triangular support panels 2, 3 analogous to those shown in Fig. 1, which are provided with respective adjacent edges connected to each other by a fold line 8, respective first and second side edges 2a, 3a opposite and respective adjacent bottom edges 2b, 3b, as can be seen when they are in an extended position shown in Fig. 33. A fixing panel 7 is articulated connected to the first lateral edge 2a of the first support panel 2. Here, the structure 10 comprises a limiting configuration in the face of a link panel 16 having an edge connected by a line of fold 17 to one edge of the fixing panel 7 and another opposite edge connected by a reversible fold line 18 to a reinforcement fin 28, which is configured to, once the structure 10 folded and assembled, be superimposed and fixed to an inner face of the second support panel 3 by means of an adhesive 29 applied to the outer face of the reinforcement fin 28 (and shown symbolically by a striped area in Fig. 33) . As a result, said link panel 16 is connected on one side to the fixing panel 7 by the fold line 17 and on the other side to the second side edge 3a of the second support panel 3 by the fold line 18.

As shown in Figs. 34 to 38, said fixing panel 7 is fixed to a rear surface of a display 50 by means of an adhesive 24 applied to the outer face of the fixing panel 7 (and shown symbolically by a striped area in Fig. 33), of such that the first lateral edge 2a of the first support panel 2 is in a fixed position in relation to the surface of the display 50, while the second lateral edge 3a of the second support panel 3 is movable together with the link panel 16.

On the link panel 16 a first fastening configuration 12 is molded and on the edge of the adhesive-free reinforcement flap 28 a second fastening configuration is molded 13. An elastic element 5 in the form of an elastic cord, or preferably an elastic ring is connected to said first fastening configuration 12, which is close to the fastening panel 7 and to said second fastening configuration 13, which is located in the second side panel 3, so that the tension of the element elastic 5 attracts the second lateral edge 3a of the second support panel 3 towards the first lateral edge 2a of the first support panel 2 and said link panel 16 towards the surface of the display 50 to move the structure 10 from a folded position to a expanded position (Fig. 34). The link panel) 6 in cooperation with e ~ contact of the second lateral edge 3a of the second support panel 3 with the surface of the exposed ~ limits the expansion of the structure in the expanded position shown in Fig. 34, in which the . First and second support panels 2, 3 adopt a partially pyramidal three-dimensional configuration. with the first and second side edges 2a, 3a opposite facing the rear surface of the display 50 and the bottom edges 2b, 3b providing a support base for supporting the upright display, generally in cooperation with a lower edge of the display 50.

In the expanded position, the link panel 16 is substantially coplanar with the equation panel 7 and attached to the surface of the display. The structure 10 is configured to be moved from the expanded position (Fig. 34) to the folded position (Fig. 38) against the thrust of the elastic element 5 by an external pressure (indicated symbolically by an arrow P in the figures) exerted on the support panels 2, 3. In a first phase shown in Fig. 35, the pressure P is applied laterally on the second support panel 3 to force the separation of the second lateral edge 3a of the second support panel 3 from the surface of the display 50 at the same time as the link panel 16 rotates around the fold line 17. During this first phase, the second support panel 3 and the link panel 16 form a convex dihedral until they reach the

situation shown in Fig. 36, when the second support panel 3 and the link panel 16 are

substantially coplanar.

From this situation, the pressure P exerted externally inward on the second

support panel 3 and / or on the link panel 16 causes the dihedral formed by the second panel

S

of support 3 and the link panel 16 goes from being convex to being concave until the link panel

16 is superimposed on the plating panel 7. Then, as shown in Fig. 37, the pressure P

can be moved on the first support panel 2 to rotate the first and

second support panels 2, 3 around the fold line corresponding to the first edge

lateral 2a and fold line 18, respectively, until the situation is completely reached

10

folded shown in Fig. 38. When the structure 10 is in the folded position, the element

Elastic 5 has a higher tension level than when it is in the expanded position. POI

consequently, when the pressure P is removed, the structure 10 automatically expands again

to the expanded position due to the tension of the elastic element 5.

In Figs. 39 to 41 a self-expanding folding side stand is shown according to the

fifteen

embodiment shown in Figs. 23 to 26 applied to an OS display comprising a plate

rectangular divided into two parts by a horizontal fold line 51. The display 50 can

be folded to a compact position by folding it along said horizontal fold line 51. In

correspondence, the first and second lateral support panels 2, 3 of the support structure 10

laterally comprise respective transverse fold lines 19 in alignment with said line

twenty

of horizontal fold 51 of the exhibitor SO. In Fig. 30 the structure 10 of the lateral support is in the

expanded position keeping the display stand SO in an upright position and with its two portions ~

coplanar. To fold the display stand SO to the compact position it is necessary, first, apply!

a pressure P on the first and second support panels 2, 3 to fold the structure 10 such

as described above, and then apply pressure P backwards on the upper portion

25

of the display 50 to start folding the display 50 along the horizontal fold line 51, with the

that the first and second support panels 2, 3 will begin to fold simultaneously by sm

respective transverse fold lines 19. Finally, and after going through a final phase of the

folding operation illustrated in Fig. 41, the two portions of the display will be

substantially superimposed with the structure 10 folded between them in a folded position

30

compact

The SO display and side stand assembly can be kept in the compact position

by applying a very light pressure despite the tension level of the elastic element 5

when the structure 10 is in the folded position it is higher than when it is in the position

expanded, it can even be kept in the compact position by the weight of one of the portions of the

35

display 50 in a horizontal position on the folded structure 10 and on the other portion of the

SO display. However, from the compact folded position, grabbing an upper edge of the

display and lifting it achieves the automatic deployment of the display 50 to the upright position and of the structure 10 of the lateral support to the expanded position.

Figs. 42 to 46 illustrate another embodiment of the lateral support of the present invention, in which the structure 10, when in an operational situation shown in Figs. 42 and 44, comprises first and second lateral support panels 2, 3 of generally triangular shape, which are connected by respective fold lines 8a, 8b to opposite lateral edges of a central support panel 4, which also It is generally triangular in shape. The central support panel 4 has an upper vertex 4a in which the vertices of the lateral support panels 2, 3 and a lower edge 4b opposite the vertex 4a converge. The first and second side support panels 2, 3 have respective first and second side edges 2a, 3a opposite and one ~

respective lower edges 2b, 3b adjacent to the lower edge 4b of the central support panel 4. When the structure 10 is in the expanded position (Figs. 42 and 44), the first and second lateral support panels 2, 3 and the panel of central support 4 adopt a general-pyramid configuration, with the first and second lateral edges 2a, 3a of the first and second lateral support panels 2, 3 facing the rear surface of the display 50 and the lower edges 2b ~ 3b, 4b of the first and second lateral support panels 2, 3 Y of the central support panel 4, providing a support base for the display 50, generally in cooperation with an edge; bottom of the display 50.

Fig. 43 shows the flat initial part from which structure 10 is formed. This: flat initial part comprises the first and second lateral support panels 2, 3 connected by their respective first and second lateral edges 2a, 3a to the lateral edges of a triangular fixing panel 7, which has a lower edge articulatedly connected to a fin in which first fastening configurations are formed 12. The second lateral support panel J, is connected in the side edge opposite the central support panel 4 by one of the fold lines 8b. The central support panel 4 and the first lateral support panel 2 are connected at their opposite edges to respective stop fins 6a, 6b by other fold lines 8a. Each of the stop fins 6a, 6b has a corresponding second clamping configuration 13 formed. The lower edge 4b of the central support panel 4 is connected to a retaining panel 21 which can be folded along a fold line. which defines the lower edge 4b.

As shown in Figs. 44 and 45, in use situation, the two stop fins 68, 6b are joined to each other by means of an adhesive 25, so that the fold lines 8a coincide forming a single fold line 8a between the first panel of lateral support 2 and the central support panel 4 and the clamping configurations 13 coincide forming a single clamping configuration 13. Alternatively, the two abutment alleles 68, 6b can be attached to each other by

stapling or any other means of attachment. The fixing panel 7 is fixed to a rear surface of a display 50 by means of an adhesive 24 applied to the outer face of the fixing panel 7.

An elastic element 5 (Figs. 44, 45), for example in the form of an elastic ring, is engaged in said first and second fastening configurations 12, 13 to attract the movable fold line 8b that connects the central support panel 4 and the second lateral support panel 3 empties the first lateral edge 2a of the first fixed lateral support panel 2 with respect to the display 50 to expand the structure 10 towards the expanded position shown in Fig. 44, while an end edge of the two butt-shaped butt fins 6a, 6b are internally supported on the first lateral edge 2a limiting the expansion of the structure 10.

Fig. 45 shows how the structure 10 can be moved from the expanded position to the folded position against the thrust of the elastic element 5 by an external pressure P exerted on the support panels 2, 3, 4, and the stop fin 6a , 6b is moved from the active position to the: inactive position by the elastic element 5 during its movement from the expanded position to the folded position. During the folding operation, the retention panel 21 can be folded and inserted between the second side support panel 3 and the display 50, so that the panel; retention retains the structure 10 in the folded position against the force of the elastic element 5 (Fig. 46). However, it is sufficient to manually initiate a movement of the structure 10 from the folded position towards the expanded position so that the retention panel 21 is released and the structure 10 quickly and automatically adopts the expanded position thanks to the push of the elastic element 5.

Figs. 47 to 51 illustrate another embodiment of the lateral support of the present invention, in which the structure 10, when in an operational situation shown in Figs. 42 and 44, comprises first and second lateral support panels 2, 3 of generally triangular shape, which are connected to each other at respective adjacent lateral edges by a fold line 8. The first and second lateral support panels 2, 3 have respective first and second opposite edges 2a, 3a opposite and respective adjacent bottom edges 2b, 3b. When the. structure 10 is in the expanded position (Figs. 47 and 49), the first and second lateral support panels 2, 3 adopt a generally pyramidal configuration, with the first and second lateral edges 2a, 3a of the first and second panels of lateral support 2, 3 facing the rear surface of the display 50 and the lower edges 2b, 3b providing a support base for the display 50, generally in cooperation with a lower edge of the display 50.

Fig. 48 shows a flat initial part from which structure 10 is famous. This flat initial part comprises the first and second lateral support panels 2, 3 connected to each other by adjacent lateral edges along the line of folding 8. The first lateral support panel 2 is articulated by its first lateral edge 2a articulated to a lateral edge of a triangular foamed pivot panel 7, which is articulably connected by its lower edge to a fin in which they are First fastening configurations are attached 12. The fastening panel 7 and the second lateral support panel 3 are connected by their opposite lateral edges 3a to respective abutment fins 6a, 6b in which second configuration configurations are formed.

clamping 13. The lower edge 3b of the second side support panel 3 is connected to a panel of

retainer 21 that can be folded by a fold line along part of the bottom edge 3b.

As shown in Figs. 49 and 50, in use situation, the fixing panel 7 is fixed to a

rear surface of a display 50 by means of an adhesive 24 applied to the outer face of the panel

5

fixing 7, and the two stop fins 6a. 6b are located adjacent to each other and connected of

movable way by means of an elastic element S, for example in the shape of an elastic ring,

hooked to said first and second clamping configurations 12, 13. In the absence of others

external forces (Fig. 49), the force of the elastic element 5 attracts the second lateral edges 3a the

towards each other by joining the two butt fins 6a, 6b against each other, so that the two

10

second lateral edges 3a coincide forming a single second lateral edge 3a between the second

side support panel 3 and fixing panel 7 and clamping configurations 13 match

forming a single clamping configuration 13. In this situation, the contact between the two fins

of stop 6 limits the expansion of the structure 10 in the expanded position.

Fig. 50 shows how the structure 10 can be moved from the expanded position to the

I S

position folded against the thrust of the elastic element S by an external pressure P exerted on ~

the support panels 2, 3, so that the two second side edges 3a are separated from each other ~

another and the two butt fins 6a, 6b, which are linked by the elastic element engaged;

in the respective second clamping configurations 13, they are moved from the active position:

Each of the first and second side support panels 2, 3 is divided into two parts by a panel fold line 2c, 3c located between the corresponding side edge 2a ~ 3a and the corresponding fold line 8a, 8b. This panel fold line 2c, 3c extends from the corresponding lower edge 2b, 3b to a vertex opposite it, and each of said stiffening tabs 15 is divided into two portions by a fold line 15a that extends from the end of the corresponding panel fold line 2c, 3c to a free edge of: the stiffening flange 15 opposite the corresponding lower edge 2b, 3b.

In a situation of use, the two fixing panels 7 can be fixed directly to one: rear surface of the display 50 by means of an adhesive (not shown) and an elastic element 5 can be attached to the first and second fastening configurations 12, 13 for attracting each other, so that the stiffening tabs 15 act to limit the expansion of the structure 10 in the expanded position in a manner analogous to that described above in relation to the embodiment illustrated in Figs. 23 to 26. However, structure 10 according to the embodiment shown in Figs. 52 and 53 are planned to be associated with a brochure holder 30.

As shown in Fig. 57, said booklet 30 is interposed between the structure 10 and the display 50, and is configured to support items such as booklets or the like (not shown) so that they are accessible through a slotted opening 52 in the display 50. The booklet 30 is foldable and can be moved between a folded position and an expanded position together with the structure 10, even with the items stored therein. In addition, the booklet 30 is hidden by the structure 10 and by the display 50 when both are in the expanded position.

Fig. 54 shows a flat initial piece from which the booklet holder 30 is connected. This flat initial piece comprises a base panel 31 having lateral edges articulately connected to respective fixing panels 42 by means of lines of fold 43. The base panel 31 includes "U" shaped cuts 32a defining a fin 35, which is articulated connected to the base panel 31 by an upper fold line 36 extending between two upper ends of said cuts in the form of "U" 323. When the fin 35 is bent by the upper fold line 36 (Fig. 57), the cuts in the form of "U" 323 the upper fold line 36 fill an opening 32 suitable for the passage of the articles, In use situation, the base panel 31 is fixed to the display 50, for example by means of an adhesive 24 (Fig. 54) with said opening 32 facing said opening 52 of the display 50.

From a lower end of the base panel 31 extends down a storage panel 33 connected by one of its edges to the base panel 31 by a line of: bottom crease 37, and cuts 38 extend from the ends of said line from the lower fold 37 to a lower edge of the base panel 31. The storage panel 33 has intentional fold lines 39 and an end edge connected to a joint panel 40 by means of: an extreme fold line 41. In situation of use (Fig. 57), the storage panel 33 is folded by the lower fold lines 37, the ends 39 and the end 41, and the joint panel 40 is fixed, for example by adhesive, to the fin 35, so that the storage panel 33 forms a support fold 34 at a lower level with respect to the opening 32. Thus, the articles are supported by said support fold 34 at the same time that they are accessible through said openings 32, 52 of the panel base 31 and exhibitor 50.

The base panel 31 of the booklet holder 30 has approximately the same dimensions as the central support panel 4 of the structure 10, and the structure 10 is attached to the booklet holder 30 by means of elastic rings 44 (Fig. 55) that hold the respective panels of fixation 7, 42 mutually attached. To facilitate the engagement of the elastic rings, the fixing panels 7 of the structure 10 have notches 7c fused together with the ends of the second edges 2a. 3a and the fixing panels 42 of the portfolio 30 have corresponding notches formed next to the ends of the fold lines 43. Preferably, the fixing panels 7, 42 of the structure 10 and of the brochure holder 30 are folded inwards before being attached and joined by the elastic rings, so that they are hidden when the structure 10 and the brochure holder 30 are in use.

Fig. 55 shows structure 10 and brochure holder 30 attached to display 50 in the expanded position. Fig. 56 shows how the structure 10 and the brochure holder 30 can be moved from the expanded position to the folded position against the thrust of the elastic element 5 by an external pressure P exerted on the support panels 2, 3, 4. During the folding operation, the retention panel 21 can be folded and divided below the display, so that the retention panel 21 retains the structure 10 and the brochure holder 30 in the folded position against the force of the elastic element 5, for example when the whole set is introduced in an envelope or similar wrap. However, simply remove the envelope assembly manually so that the panel

retention 21 is released and the structure 10 quickly and automatically adopts the expanded position thanks to the push of the elastic element 5. It will be understood that the structure 10 according to any of the embodiments of the lateral support described above can be applied to a folding display of a manner 5 analogous to that described in relation to Figs. 39 to 41.
