Abstract

Book or booklet comprising several pages of texts and / or illustrations, produced by folding a sheet, characterized in that the folding of the sheet is made in a snail, forming several flaps (V1 to V5) all folded around parallel hinges.

Description

Book or booklet obtained by folding.

  The present invention relates to a booklet or a book, generally of small size obtained by folding a sheet of paper, cardboard or other suitable material, intended to present various texts and / or illustrations. Such a booklet is particularly suitable for children's literature, and may include an association of texts and illustrations.

  In particular, illustrated books generally require the cutting of a large number of sheets proportional to the number of pages in the book.

  Moreover, when flipping through an illustrated book or album, it is generally not possible or not intended to keep in front of a printed text several illustrations, especially those printed on the preceding pages of the book. .

  Books or guides are known, including tourist guides, which include pamphlets that are supposed to allow the presentation of larger-sized illustrations than the book, and thus make reading more attractive, especially for young children. it is a children's book. In this case, however, the leaflet requires a particular cut of a sheet which is inserted into the various sheets constituting the book. In addition, the folding, usually made accordion, is designed to be fully unfolded for the presentation of its content or, conversely, completely folded when the book is closed. Sometimes such illustrated books, formed by folding an accordion sheet are used by unfolding, each time forming a double page illustrated. We do not try to benefit from the total length of the unfolded sheet.

  In other known embodiments, the booklet comprises several flaps folded in several directions around fold lines perpendicular to each other so as to form, after unfolding completely, a board of width and height corresponding to the dimensions of several flaps.

  In any case, it appears that the known books or albums do not allow an easy and attractive presentation of the information or illustrations contained in the book. In addition, the known devices are complex to achieve and therefore lead to a significant increase in the cost of this type of work.

  The present invention relates to the production of a book, in particular a small book, such as a booklet, comprising several pages of text or illustrations, in which the folding allows a matching of different parts or different pages of the book, for a more attractive and easier reading.

  The invention also relates to such a booklet, which is simple to manufacture and therefore a very reasonable cost.

  The invention thus allows the presentation of an illustration of great length in a small format.

  The invention also allows the realization of a book of several pages, which requires the cutting of only one sheet for its realization.

  Finally, the present invention relates to such a booklet, allowing reading page by page without losing sight of the illustrations of the previous pages.

  In one embodiment, the booklet comprises several pages of text and / or illustrations, and is made by folding a snail leaf, so as to form several flaps each comprising upper and lower edges and side edges, said flaps being all folded around folding lines parallel to the lateral edges of the flaps.

  One can thus obtain, in the unfolded state, a page whose length substantially corresponds to the width of several flaps, by means of a single sheet not cut and not stitched.

  In a preferred embodiment, the booklet comprises a first flap whose back forms the front cover, a second flap whose back forms the back cover and several additional flaps following the second flap in the longitudinal direction perpendicular to the fold lines. Advantageously, the back of at least some of the additional flaps or all the additional flaps, presents a text and / or illustration in intellectual or visual connection with a text and / or an illustration on the front of the previous flap.

  With this arrangement, the unfolding of each additional component initially folded into snail, to discover, for example information corresponding to the contents of the front of the previous pane, appearing next to the back of the unfolded flap. In addition, as and when successive unfolding flaps, the information materialized by the text and / or illustrations on the front of the previously unfolded flaps remains visible, the assembly forming a band whose length increases the width of the flaps. a shutter at each unfolding and which forms a kind of long longitudinal panoramic poster.

  Note that the length of the band is optionally increased depending on the material used, the width of the hinges formed around the fold lines of the various components.

  In a preferred embodiment, one of the faces of the sheet, corresponding to the back or the front of all the shutters, is printed in colors and the other side in black and white. This allows a significant saving on printing costs while giving the reader the feeling of a book in color when unfolding successive shutters.

  One of the faces of the sheet, corresponding to the back or the front of all the flaps, may for example advantageously comprise illustrations, preferably in color and the other side of the texts printed in black on a white background. The unfolding of the successive shutters generates a long illustrated panoramic strip of which each portion can be the subject of a specific comment printed on the back of the shutter not yet unfolded.

  In an advantageous embodiment, the booklet further comprises a cover, for example hardcover, fixed on one of the faces of one of the flaps and covering the two sides of the booklet in the fully folded state.

  The cover can be fixed by its back on the back of the second component, for example by gluing.

  Preferably, the cover is made of a material more rigid than that of the sheet constituting the flaps, for example, cardboard, and the cover is glued on the printed side in black and white, thus showing in the completely unfolded state , the entire front of the sheet printed in color.

  The invention will be better understood on studying the detailed description of an embodiment taken by way of non-limiting example and illustrated by the appended drawings, in which: FIG. 1 schematically illustrates an embodiment of the invention; invention, showing a booklet in the folded position with the cover partially open; FIGS. 2a to 2d illustrate the appearance of the booklet according to the invention, as it unfolds; FIG 3a is a view showing the front of the unfolded sheet constituting the booklet of the invention; and FIG. 3b is a view of the back of the same sheet, also in the unfolded state.

  As illustrated in Figure 1, the booklet according to the invention is made by folding a single sheet of paper, referenced 1 as a whole. The sheet 1 is folded into a snail, defining five flaps, referenced V 1, V 2, V 3, V 4 and V 5.

  In the example illustrated, the booklet thus constituted by the five aforementioned flaps is associated with a cover 2 more rigid than the sheet 1 and of appropriate dimensions to those of the sheet 1 in the folded state, as illustrated in FIG. All five flaps V1 to V5 is fixed, for example by gluing, on the back 2a of the cover 2. The adhesive layer 3 is placed between the cover back 2a and the outer face of the second flap V2. When the first part 2b of the cover 2 is closed, the assembly constituted by the cover 2 and the snail folding of the sheet 1 constitutes a booklet which can have a conventional library format or a small format, for example for young children. In a variant, the sheet 1 can be made of rigid or cardboard paper and the cover 2 removed. The back of the flap V1 then forms the front cover, while the back of the flap V2 forms the back cover.

  The snail folding visible in FIG. 1 shows that all the flaps are all folded around fold lines forming hinges C1, C2, C3 and C4, the width of these hinges depending on the thickness of the sheet 1 and decreasing. from C1 to C4. The fold lines are all perpendicular to the unfolding of the flaps. Reading or observation of the book can be done, after opening around the fold line C1 of the cover 2b in the direction of the arrow 5 and observation of the back of the first flap V1, by successive unfolding of the additional flaps V3, V4 and V5 to the right in FIG. 1, in the direction of the arrow 4 around the folding lines C2, C3 and C4.

  It will be noted that each flap V1 to V5 has an upper edge 6, a lower edge 7 and two lateral edges forming the respective fold lines C1 to C4. Only end flaps V1 and V5 have a free lateral edge 8, 9. All fold lines C1 to C4 are thus parallel to each other and at the same time perpendicular to the folding and unfolding direction of the flaps.

  Figures 2a to 2d make it possible to understand how to use the booklet according to the invention.

  In FIG. 2a, the cover 2 has been completely opened and on the right side of FIG. 2a, that is to say, above the back 2a of the cover 2, the stacking of the shutters V, at V5, all folded. The back of the first component V, may, for example, include a text constituting the title of the book. This text is referenced To in Figure 2a.

  The first unfolding operation is in the direction of the arrow 5 (Figure 1), the back of the flap V1 is applied on the part 2b of the cover 2. It then appears in Figure 2b the front of the flap V1 which has, in the illustrated example, a first illustration referenced I. Given the unfolding of the first flap V 1 in the direction of the arrow 5, is also shown on the right side of Figure 2b the back of the third flap V3 . In the example illustrated, the back of the flap V3 comprises a text referenced T, which is in intellectual and visual connection with the illustration I1 which appears on the front of the flap V1 and which appears immediately next to it, as seen on the Figure 2b.

  The remainder of the unfolding is always in the same direction, namely in the direction of the arrow 4. It then appears (Figure 2c) the back of the fourth component V4 which, in the illustrated example, includes a text referenced T2 which is in intellectual connection with the illustration I2 on the front of the second component V2 which was discovered by the latter unfolding. In addition, in the illustrated example, care was taken to design illustrations I1 and I2 as a logical sequence.

  The following unfolding gives rise to the state shown in Figure 2d, which shows a text on the back of the fifth component V5 which is advantageously related to the illustration I3 on the front of the third component V3 which has been discovered by the last unfolding. As before, the three illustrations I1 I2, I3 form a logical succession, representing here a landscape, then the appearance of the sun and the appearance of rain.

  The last unfolding, always in the direction of the arrow 4, gives the state illustrated in Figure 2e where we see appearing the front of the fifth flap V5 and the front of the fourth flap V4, which respectively show the illustrations I5 and I4. In the illustrated example, these two illustrations which form the last visual obtained by unfolding, realize a unique figure constituted here by a schematized rainbow.

  Referring to FIG. 3, it will be seen that the booklet of the invention, apart from the cover 2 which may be used in some embodiments, but may also be omitted, is made by folding. of a single sheet. The production of the booklet therefore requires only one cut. In addition, the sheet is printed on one of its faces which corresponds to the front of the five panels VI to V5, for example in four-color for the formation of successive illustrations. The front of the sheet thus printed forms, in the fully unfolded state, a frieze whose length is equal to five times that of the average width of a single flap which corresponds substantially to the size of the book. The successive flaps have, in practice, a decreasing width to take into account the thickness of the folded leaf snail and thus allow the definition of successive hinges.

  The first two components VI and V2 can be of the same width. Then the shutters V3 to V5 have for example, according to the grammage of the sheet used, a decreasing width each time of about 2 to 8 mm.

  The back of this same sheet, visible on the lower part of FIG. 3, which represents the same returned sheet, shows an impression, here for example in black and white, comprising all the texts intended to correspond to the different illustrations.

  In the example shown, the back of the second flap V2 is not used since it constitutes the bonding face of the cover 2. On the other hand, we see that the text TI of the third flap V3 corresponds to the image II of the first part VI. The text T2 of the fourth component V4 corresponds to the image 12 of the second component V2 and the text T3 of the fifth component V5 corresponds to the image I3 of the third component V3.

  Such a small format book can be read and observed by successively unfolding the various components until obtaining a complete frieze, for example illustrated. With each unfolding of a shutter, the illustration can be enriched, complemented or unveiled to offer, at the end of the unfolding, a rich and long illustrated frieze.

  Such a booklet is for everyone, but especially for young children. In this case, indeed, with each flap turned, the child sees under his eyes the illustration lengthen. At each moment of the story, he can ask a question about the previous steps or remember what happened from the beginning. At the end of the book, in front of this long illustrated frieze that unfolded to him over the unfolded shutters, the child contemplates a vast panoramic picture and can return to the whole action.

  In the illustrated example, the booklet has five parts, but it will of course be understood that it may contain a larger number.

  In the example shown, the first three parts present the first three sequences of a small story, while the last two parts form a last double illustrated page. In this example, the composition of the drawing can thus be wider than on the previous individual shutters.

  Of course, it will be understood that any variant with regard to the arrangement of illustrations and / or texts may be considered. Such a booklet can be conceived only with text, which, again preferably, can proceed in a logical manner as the flaps are unfolded. You can also design such a booklet for very young children, only with illustrations, both on the back and on the front of the different components.

  The invention thus allows the realization of a book, which is both a small book and a long panoramic poster. In the case of four-color process printing, as in the example illustrated above, the invention makes it possible to achieve a noticeable saving in printing, by producing four-color printing on the front and printing in black and white on the back.

  The invention also makes it possible to obtain a book that is particularly economical, requiring the cutting of only one page per book, without any stitching and without binding, the book being formed by simply folding the first part on the whole other shutters folded into snails.

  The invention makes it possible, if desired, to develop adapted scenarios providing for the step-by-step discovery of a set that is only revealed when the work is completely unfolded. When reading, a discovery, a transformation, a meeting or an action that supports the interest of readers throughout history, appears with each unfolding of a component. Once the set is fully unfolded, the illustration can form a coherent and balanced whole looking like a panoramic poster.

  In general, one can, thanks to the invention, present a little story that is revealed only step by step and gives the possibility of a final fall when the book is completely unfolded.

  Although the invention has been illustrated from an example of a horizontal course, it will of course be understood that vertical unfolding can also be conceived.
