Abstract

The panel (1-3) is made from a rigid material with a printed centre, e.g. with a calendar, and a surround with one or more fold lines (4,4'). The surround is also partly pre-cut so that it can be folded along the fold lines and make a stand which allows the calendar to be placed on a horizontal surface. A flat strip of material can be used to hold the edges of the fixed and folded sections. Variants of the design can be made with different folding surround sections to make the calendar stand up.

Description

 The present invention relates to printed rigid plates.

 The devices known in this field generally relate to the field of calendars and usually consists of a printed plate comprising a member for suspending the plate from a wall, or other vertical support.

 The printed rigid plate, object of the present invention, incorporates a device for erecting the plate on a horizontal support, which makes it possible to put this plate in a practical manner on a desk, for example.

 The printed rigid plate, object of the invention, which can be erected in stable equilibrium on a support surface, is produced in a blank of material of constant thickness; each of the two sides of the blank being inscribed in a plan, in the unfolded position of the plate. The plate has one or more fold lines and is composed of a first part constituting a flap articulated by means of the fold line or lines with respect to a second part of the plate - called the main part - constituting the support of the zone. printed erect. When one face of the flap is inclined by folding with respect to a face of the main part at an angle suitable for the stable equilibrium of the plate on a bearing surface, at least one spacer element, attached to the plate , connects the flap to the main part to maintain the distance of this angle between the flap and the main part.

 According to one embodiment of the invention, one or more lines for cutting the plate cooperate with the fold line or lines to delimit the flap.

 According to one embodiment of the invention, the flap folds in a first gyratory direction relative to the main part, to determine a first folded position of the plate, and folds in a second gyratory direction, opposite to the first gyratory direction, to determine a second folded position of the plate. The flap is located on the back side of the main part in the first folded position, while in the second folded position, the flap is located on the front side of the main part. The spacer is reversible in position to connect the flap to the main part, whatever the folded position of the plate.

 According to one embodiment of the invention, the plate consists of a rigid core, each face of which is laminated to a sheet or to a flexible film.

A material recess is produced along each fold line, by cutting the core. This cutting operation is performed before the laminating operation of the flexible sheets or films.

 According to one embodiment of the invention, the cutting line or lines delimiting the flap and the main part are produced after the laminating operation.

 According to an embodiment of the invention, the fold line or lines are arranged along an axis parallel to the surface on which the plate is erected.

 According to one embodiment of the invention, the flap consists of at least two separate edges of the plate.

 According to one embodiment of the invention, there are two fold lines. Each fold line connects an edge of the plate to one end of a line for cutting the plate, and each line for cutting delimits the upper part of the printed area intended to be erected. One fold line connects a first edge of the plate and the other fold line connects a second edge of the plate opposite the first edge.

 According to one embodiment of the invention, the two folding lines connect the ends of the same single cutting line for the plate. One fold line connects one end of the cut line, while the other fold line connects the other end of the cut line, the flap having a general U-shaped configuration.

 According to one embodiment of the invention, the flap is constituted by a single edge of the plate, by a single fold line, and by two cut lines. One end of the fold line joins one end of the first cut line, the other end joins an edge of the plate.

The other end of the fold line joins one end of the second cut line, the other end of which joins the same edge of the plate. The two cutting lines delimit on the main part, in the folded position of the plate, two printed zones arranged on either side of the recess produced in the plate by folding the flap.

 According to one embodiment of the invention, one end of the spacer is fixed to the plate when it is unfolded.

 According to one embodiment of the invention, the two ends of the spacer are removably attached to the plate when the latter is folded.

 According to one embodiment of the invention, the end of the spacer element fixed to the plate when it is unfolded is produced in the form of a U-shaped clamp clamping the thickness of the plate to the place of an edge of the plate.

 According to one embodiment of the invention, one end of the spacer comprises a part which, in the folded position of the plate, after passing through a hole in the plate, abuts against the plate or against an element secured to the plate.

 According to one embodiment of the invention, the hole constitutes a member for suspending the plate against a vertical surface.

 According to one embodiment of the invention, at the location of one of its connections with the plate, the spacer element is foldable along an axis arranged parallel to the bearing surface of the plate.

 According to FIGS. 1 to 19, the printed rigid plate 1 which can be erected in stable equilibrium on the support surface Sa, is produced in a blank 3 of material of constant thickness. Each of the two sides Ro or Vo of the blank 3 are inscribed in a plane pli or pl2, in the unfolded position of the plate 1-3 (FIGS. 1 and 2), the face Ro being inscribed in the plane p11 and the face Vo being inscribed in the p12 plane which is parallel to the pil plane. Plate 1-3 has two fold lines 4, 4 ′ and a cut line 5 for plate 1-3. The fold lines 4, 4 'cooperate with the cut line 5 in order to delimit a first part 6 of the plate 1-3 constituting the flap 6. The flap 6 is articulated via the fold lines 4, 4' by relative to a second part 7 of the plate 1-3 - said main part 7 - constituting support 7 of the erected printed area 8. When the face F1 or F3 of the flap 6 is inclined by folding relative to the face F2 or F4 of the main part 7 at an angle V suitable for the stable equilibrium of the plate 1-3 on the bearing surface Sa, a spacer 2, attached to the plate 1-3, connects the flap 6 to the part main 7, to maintain the distance of this angle V between the flap 6 and the main part 7.

 According to Figures 6, 7, and 8, the plate 1-3 consists of a rigid core 25 of solid cardboard, each side 9 or 10 is laminated to a flexible sheet 11 or 11 'of paper. A recess 12 or 12 ′ of material is produced along each fold line 4 or 4 ′, by cutting the core 25. This cutting operation (shown in FIG. 6) is carried out before the laminating operation ( shown in Figure 7) flexible sheets 1 1 11 ', while the cutting line 5, delimiting the flap 6 relative to the main part 7 is produced after the laminating operation (see Figure 8).

 According to Figures 9 and 10, the configuration of the fold lines 4 and 4 ', resulting from the particular shaping of the plate 1-3, implies that at the location of the fold lines 4 and 4', only the two flexible sheets 1 1 and 11 'constitute the fold lines 4 and 4', the material of the core 25 being removed along the recesses 12 and 12 '. The fold lines 4 and 4 ′ consequently constitute a flexible articulation allowing the fold of the flap 6 relative to the main part 7, without the rigid plate 1-3, having a large thickness, deteriorating at the level of the fold lines 4 and 4 '. This configuration makes the invention particularly suitable for the production of calendars obtained by shaping a plate comprising a core of solid cardboard laminated on each of its two faces by a sheet of paper, each sheet mentioning the months of the year. As such, the drawings 1 to 19 represent a calendar constituted by the plate 1-3, the front Ro mentions, at the place of the main part 7, the months from January to July, while its back Vo mentions, at the location of main part 7, the months of July to December, as well as the month of January of the following year.

 According to FIGS. 1 and 13, and in particular FIGS. 1 and 2, each fold line 4 or 4 ′ connects an edge 13 or 14 of the plate 1-3 to an end 15 or 16 of the same single cutting line 5 of plate 1-3, the cutting line 5 delimiting the upper part 17 of the printed area 8 intended to be erected. The flap 6 is constituted by three separate edges 13, 26, 14 of the plate 13, so as to create a printed area 8 optimized, in surface configuration, for its printing. According to the example shown in drawings 1 to 19, the upper part 17 of the printed area 8, determined by the configuration of the cutting line 5, is located in the central position in the plate 1-3 and its entire rectangular shape allows printing a continuous block of text or drawing (in the example of the accompanying drawings, this is a series of months).

 Still according to FIGS. 1 and 13, and in particular FIGS. 1 and 2, a fold line 4 connects a first edge 13 of the plate 1-3 and the other fold line 4 'connects a second edge 14 of the plate 1 -3 opposite the first edge 13.

A fold line 4 connects one end 15 of the cut line 5, while the other fold line 4 'connects the other end 16 of the cut line 5, the flap 6 having a general U-shaped configuration .

 According to FIG. 13, the two fold lines 4, 4 ′ are arranged along an axis X-X ′ parallel to the surface Sa on which the plate 1-3 is erected.

 According to Figures 1 to 4, one end 18 of the spacer 2 is fixed to the plate 1-3 when it is unfolded. This end 18 is produced in the form of a U-shaped clamp 18 tightening the thickness e of the plate 1-3 at the location of the edge 21 of the plate 1-3. The spacer 2 is made of a plastic material and has a line of reduced thickness 27 disposed on an edge of the U-shaped profile formed by the clamp 18. According to Figures 3 and 4, this line 27 affects a profile V-shaped allowing the folding of the spacer 2 following the hollow of this V. The use of the thinner line 27 as the folding member of the spacer 2 minimizes the thickness clean e 'of the spacer 2 in order to obtain a final product 1-3 having itself a minimized thickness, which optimizes the packaging during the superimposition or juxtaposition of a plurality of plates 1- 3 identical.

According to Figure 14, the spacer 2 is foldable along an axis Y
Y 'arranged parallel to the bearing surface Sa of the plate 1-3, the thinner line 27 being arranged along this axis Y-Y'.

The end 19 of the spacer 2 not fixed to the plate 1-3 when it is unfolded comprises a part 22 which, in the folded position of the plate 1-3 (Figures 14 and 15), after passing through the through a hole 23 made in the plate 1-3, abuts against the eyelet 28 bordering the hole 23, the eyelet 28 being secured to the plate 1-3. According to the configuration of the two ends 18, 19, these two ends 18, 19 of the spacer 2 are removably attached to the plate 1-3 when the latter is folded. Furthermore, according to FIG. 5, the hole 23 constitutes a suspension member 23 of the plate 1-3 against the vertical surface
Sv, when the plate 1-3 is in the unfolded position, the nail 42 fixed to the vertical surface Sv being placed inside the hole 23.

 Figures 11 to 14 and 16 to 19 clearly explain the simple assembly method of the calendar 1-3 produced according to the invention.

 According to Figure 11, the user of the device folds the flap 6 relative to the main part 7 in a first gyratory direction G1 and also folds the spacer 2 in the direction S1 at the location of its line of least thickness 27.

 According to FIG. 12, the user then forcibly passes the end 19 of the spacer 2 through the circular hole 23 made in the plate 1-3.

 According to FIGS. 13, 14 and 15, once placed on the bearing surface Sa, the plate 1-3, by its weight, so much to spread the flap 6 away from the main part 7, which pushes the enlarged part 22 ( see Figure 15) in abutment against the eyelet 28 secured to the plate 1-3. The spacer 2 then maintains between the flap 6 and the main part 7 an angle V suitable for the stable balance of the plate 1-3 on the bearing surface Sa.

 Figures 11 to 14 describe a first folded position P1 (noted in Figures 12, 13 and 14) of the plate 1-3, position determined by the direction of rotation G1 of the flap 6. In this first position P1, the flap 6 is located on the back side Vo of the main part 7 (see Figures 12 and 14).

Figures 16 to 19 illustrate a second folded position
P2 of plate 1-3 (position noted in Figures 18 and 19). According to Figure 16,
The user of the device folds the flap 6 relative to the main part 7 in a second gyratory direction G2, opposite to the first gyratory direction G1, to determine the second folded position P2 of the plate 1-3. In this second folded position P2, the flap 6 is located on the side of the front side Ro of the main part 7 (see FIG. 18).

 The spacer 2 is reversible in position for connecting the flap 6 to the main part 7, whatever the folded position P1 or P2 of the plate 1-3.

 Figures 14, 16, 17, 18 and 19 describe more precisely the passage from the first folded position P1 of the plate 1-3 to the second folded position P2.

 From the first folded position P1 shown in Figure 14, the flap 6 is folded in the second gyratory direction G2 (Figure 16), while the spacer 2 is removed from the edge 21 of the plate 1-3 , the clamp 18 making a removable connection with this edge 21. According to FIG. 17, the spacer element 2 is fixed on the edge 21 in a reverse position relative to the position it occupied in FIG. 14, c '' is to say that the thinner line 27 which was on the back Vo of the main part 7 in Figure 14 is now located on the front Ro of this main part 7 Similar to the assembly described in Figure 12, according to the FIG. 18, the user of the device, by pivoting the flap 6 still in the direction G2, forces the end 19 of the spacer 2 to pass through the hole 23 to determine the second folded position P2.

Once the plate 1-3 is placed in stable equilibrium on the support surface
Sa, according to FIG. 19, the position P2 visually highlights, for the user of the device, the months of July to December of the current year, as well as the month of January of the following year, while according to FIG. 13, the position P1 visually highlights, for the user of the device, the months from January to July.

 FIG. 20 shows the production of a printed plate 1-3 according to the invention, but comprising a single fold line 4. The flap 6 is constituted by three distinct edges 33, 34, 35 of the plate 1-3 and by the cutting line 90. Like the previous embodiment, this variant of the invention also delimits a printed area 8 allowing the printing of a continuous block of text; however, according to this figure 20, the flap 6 is weakened by its configuration compared to the embodiment, presented by Figures 1 to 19, and incorporating two fold lines 4 and 4 '.

 According to the variant shown in FIG. 21, the fold lines 4 and 4 ′ are two in number and the flap 6 is constituted by two separate parts 31 and 32. The flap 6 is also constituted by three distinct edges 43, 44, 45 of plate 1-3. Each fold line 4 or 4 'connects an edge 43 or 45 of the plate 13 to one end 80 or 81 of a cutting line 82 or 83 of the plate 1-3.

Each cutting line 82 or 83 delimits the upper part 17 of the printed area 8 intended to be erected. A fold line 4 connects a first edge 43 of the plate 1-3 and the other fold line 4 'connects a second edge 45 of the plate 1-3 opposite the first edge 43. In this case, the flap 6 must be connected to the main part 7 of the plate 1-3 by two spacers 2 and 2 ', which makes handling more complicated, when mounting the plate 1-3, compared to the embodiment presented. by Figures 1 to 19.

 According to the variant shown in Figure 22, the flap 6 is constituted by a single edge 50 of the plate 1-3, by a single fold line 4, and by two cutting lines 52, 53. One end 54 of the line folding 4 joins one end 55 of the first cutting line 52 whose other end 56 joins the edge 50 of the plate 1-3. The other end 57 of the fold line 4 joins one end 58 of the second cutting line 53, the other end 59 of which joins the same edge 50 of the plate 1-3. The two cutting lines 52, 53 delimit on the main part 7, in the folded position of the plate 1-3, two printed zones 70-71 arranged on either side of the recess 72 produced in the plate 1-3 by folding the flap 6. According to this variant of the invention, the total printed area 70-71-73 has a U shape allowing the printing of two blocks of text each mentioning three months of the year. In this case, the flap 6 offers the advantage of being able to be produced in a compact form.

However, the total printed area 70-71-73 is split in the middle, the discontinuity of this area 70-71-73 could, in certain cases, affect its optimization.

 According to the variant shown in Figures 23 to 26, each of the two sides Ro or Vo of the blank 3 making up the plate 1 are inscribed in a plane pl3 or pl4, in the unfolded position of the plate 1-3 (Figures 23 and 24), the face Ro being inscribed in the plane pl3 and the face Vo being inscribed in the plane pl4 which is parallel to the plane pl3. This plate 1-3 has a single fold line 4 connecting the sides 75 and 76 of the plate 1-3 to delimit the flap 6 relative to the main part 7, this flap 6 being constituted by the edges 75, 76, 77 from plate 1-3. The spacer 2, fixed to the edge 77 of the plate 1-3 by means of its end 18 in the form of a clamp 18, comprises two lines of lesser thickness 27 and 27 ′ allowing the folding of this element of spacing 2 so that its end 19 penetrates by force through the hole 23, in the folded position of the plate 1-3 (Figures 25 and 26). According to this last embodiment of the invention, the visual presence of the end 19 and of the hole 23 on the front face of the plate 1-3 (FIG. 25) however achieves an aesthetic damage to the final appearance of the product.

 The device, object of the invention, can be used as a rigid printed plate which can be erected in stable equilibrium on a support surface, a particularly advantageous application being the field of calendars.
