FR2791923A3 - Foldable book for teaching infants has leaves folded together in pairs and carrying information corresponding between pairs - Google Patents

Abstract

The foldable book for teaching infants has leaves (2) of the same formed pivoted together in pairs (3) to allow successive placing flat. The group of leaves form a Zig-Zag array to form a compact square surface. The leaves carry information on their front and rear surfaces to allow a correspondence between the exposed face of one leaf and one of the two faces at the time of unfolding.

Description

1 2791923

  The present invention relates to a foldable book and in particular a

  educational and / or fun book for children.

  Traditional books are generally formed by a number of sheets of the same format linked or assembled together in a common articulation region constituting the back of the book, by various means such as broaching, gluing, ring binders or analogues, etc. In these books, the sheets can be more or less thick and even be rigid, as is often the case with books for young children. The book is generally read by passing the pages successively in review. A linked sheet can be associated with another unbound sheet, articulated (sometimes by a simple folding of an extension of the linked sheet) on an edge of the linked sheet, so that it can unfold, and make a sheet appear more larger than the format of the book, for example for the purpose of placing a large format illustration, or to reveal only when the sheet is unfolded

its back, previously hidden.

  The object of the invention is to widen the possibilities of unfolding a

  book, especially in the field of educational books.

  The subject of the invention is a book formed from n sheets of the same format, characterized in that the n sheets are assembled two by two by an articulation, so as to be able to unfold successively flat in a linear series of n sheets, this following extending in a direction not

  exclusively rectilinear, and able to fold in the form of a book.

  Advantageously, the series extends in a zigzag to form a compact surface, that is to say in which each sheet, with the exception of the sheets of the edge and of the corners, is surrounded by four sheets adjacent to its edges (the central leaf being attached to only two of them), the edge and corner leaves being adjacent to only three and two leaves respectively. The surface advantageously comprises the same number of columns and rows. It is a square if each sheet is itself square, but it is not an obligation: the sheets could be rectangular, even of any shape as long as it allows a

  overlap when the sheets are folded over each other.

  It is preferable that each sheet is rigid or semi-rigid, and produced for example from cardboard, plasticized cardboard, or plastic. Each sheet is articulated to an adjacent sheet by a hinge made of flexible material, such as a plastic material, advantageously transparent. According to an important characteristic of the invention for its educational applications, at least certain sheets contain on their front and / or their back information organized so that there is a correspondence between the visible face of a sheet not yet unfolded, and

  one of the two previously hidden faces that appear when unfolding.

  This correspondence is generally a logical correspondence of the question / answer type, the answer only appearing when the corresponding sheet is unfolded. Other features and advantages of the present invention

  will emerge from the description below of an exemplary embodiment of

  the invention illustrated in the accompanying drawings in which: - Figure 1 is a view of one side of the unfolded book according to the invention, - Figure 2 is a view of the other side of the unfolded book of Figure 1 , - Figures 3 to 6 show in perspective four stages of

  unfolding of the book according to the invention.

  Book 1 is made up of 9 square sheets 2, marked a to i. The sheets 2 are rigid and articulated to each other by a flexible hinge 3 for example made of transparent plastic arranged on one side of the sheet and allowing two adjacent sheets 2 to fold over one another, whatever regardless of the thickness of the sheets or the stack of sheets already folded. The hinges are arranged so that the sheets 2 form three rows abc, def, and ghi, within which the intermediate hinges 3 are vertical (taking reference to Figure 1), the rows being interconnected at the level of horizontal hinges 3 provided between the sheets c and d on the one hand and f and g on the other hand. The continuation of sheets 2 thus forms a

  zigzag covering a substantially compact square surface.

  We have designated by Q1 to Q7 and Ri to R7 seven questions and corresponding answers and Figures 1 and 2 show their arrangement on sheets 2, organized so as to allow their logical appearance during the

  unfold Book 1, as shown in Figures 3 to 6.

  There is shown in Figure 3 the book already partially open, that is to say after having unfolded sheets a and b which can serve as a cover for the book when it is in its conventional form of closed book. The sheets a and b bear on the face visible in FIG. 1 for example

  illustrations, book title, etc., but no questions / answers yet.

  Starting from the closed book and opening the sheet a, we discover the stack of other sheets 2, above which is the sheet c revealing the first question Ql. By unfolding to the right this sheet c, with all of its underlying stack, we discover on the one hand sheet b letting see the answer Ri to question Q1, while the stack of sheets 2 still folded on sheet c is surmounted by the sheet d which then reveals the question Q2. By unfolding down the stack surmounted by sheet d, according to arrow 4 in Figure 3, we let appear the answer R2 readable on sheet c, while also appears the new question Q3 on sheet e surmounting the stack whose unfolded sheet forms the base. The unfolding of the book is continued by unfolding according to arrow 5 the sheet e and the associated sheets, and the process continues naturally as illustrated in FIGS. 4 to 6, gradually discovering the questions then the associated answers, until you have fully laid flat all of

  leaves. Just reverse the process to close the book.
