Description

Title of the invention: A deck of cards featuring a homogeneous perforated coding. Technical field of the invention

[0001] The present invention relates to the field of physical coding and punched cards. The present invention relates to a coding system and punched cards implementing said coding system. More particularly, the present invention relates to a set of coded cards. State of the art

[0002] A number of card games based on the question / answer principle are known. For example, it is common to use cards that have questions on one side and answers on the other.

[0003] In this classic system, the questions and answers are directly visible to the user. Furthermore, this type of card necessarily associates only one question with one answer. It is not possible to combine several inputs and associate them with one or more outputs. This latter type of question / answer is particularly desirable for learning arithmetic (multiplication, addition) or verb conjugations. For example, two numbers (each used as an input) can be associated with another number (an output) corresponding to the multiplication or addition of these two inputs. Alternatively, a verb, a tense, and a person (three inputs) can be associated with a conjugated form of the verb (an output).

[0004] Another type of card is known that allows these latter actions. For example, application KR102031483B1 describes a series of question / answer cards for learning addition. A first series of cards, each comprising an initial input in the form of a number printed on one side of the card and a perforation. Another series of cards, each comprising an input in the form of an operation and a printed number, and a series of possible outputs.

[0005] Superimposing a card from the first series onto a card from the second series makes it possible to display the solution through the perforation which reveals the appropriate output while the other outputs in the series of outputs are masked by the rest of the card.

[0006] However, this latter type of question / answer cards is not entirely satisfactory. Firstly, the series of possible answers is displayed clearly on one of the cards, which gives the user a clue as to the expected answer.

[0007] Furthermore, the perforation is located at a specific point on the card, corresponding to an area of ​​the card containing the answers, which gives the user an additional clue.

[0008] Ultimately, this type of card game must be divided into two series, one containing the answers and the other containing the perforations. This increases the production cost and limits the possibilities for use.

[0009] The present invention aims to solve the problems listed above. More particularly, it provides a card, usable in a question / answer game, in which: - The answers are coded and unreadable by the user, - each card can serve as a source of questions and answers, - the perforations are arranged so as to be indistinguishable from one card to another. Summary of the invention

[0010] Thus, the present invention relates to a set of cards of the same dimensions, each having on the same face a first symbol, a second symbol and a perforated area, characterized in that: The perforated area comprises perforations arranged relative to each other in the same way from one card to another. the second sign comprising a set of points, the arrangement of the points being specific to said first sign of the same card, characterized in that the position of the perforated area is offset from one card to the other and in that said offset is specific to said first sign of the same card.

[0011] In the context of the present invention, the term "game" refers to the set of cards and not to the playful activity.

[0012] In the context of the present invention, the term "same dimension" means elements having the same length and the same width.

[0013] In the context of the present invention, the term "specific" means: - that each first sign corresponds to a unique arrangement, in relation to the other cards in the game, of the points in the set of points, - that each first sign corresponds to a unique offset, in relation to the other cards in the game, of the perforations.

[0014] In the context of the present invention, the term "arranged identically relative to one another from one card to the next" means, firstly, that all the cards in the same deck have the same number of perforations. Furthermore, by using the centroid of the lowest and leftmost perforation on each card as the origin of an orthonormal coordinate system, each perforation on a card corresponds to the same position. in all the cards of the game. Moreover, from one card to another, the perforations having the same position in said orthonormal coordinate system are of the same size and the same shape.

[0015] In the context of the present invention, the terms "top" and "left" are used with reference to the card arranged so that said first sign is presented in the normal reading direction.

[0016] Consequently, it is possible by superimposing all the cards of the same deck, and offsetting them from each other, to superimpose all the perforations so as to form channels of constant cross-section from the card placed above the stack to the card placed below the stack.

[0017] In the context of the present invention, the terms "offset" and "offset" are meant to mean that from one card to another the same perforation (that is to say a perforation having the same position in said orthonormal frame) is positioned at a different distance from at least one edge of said cards.

[0018] According to a preferred embodiment, said second sign and the perforated area have substantially the same dimensions and are arranged on either side of an axis of symmetry separating the card into two identical surfaces.

[0019] In the context of the present invention, "the perforated area" is the minimum continuous surface containing all the perforations of a card.

[0020] According to a preferred embodiment, said offset is an offset in the direction of the length and / or the width.

[0021] In the context of the present invention, the terms "length" and "width" are used with reference to the map. The terms "height" and "length" are used interchangeably. In the case of a square map, one of the two dimensions may be arbitrarily designated as the length and the other as the width.

[0022] According to a preferred embodiment, said offset in the width direction between two cards of the same deck is equivalent to n times the width of a perforation.

[0023] According to a preferred embodiment, said offset in the length direction between two cards of the same deck is equivalent to m times the height of a perforation.

[0024] In the context of the present invention, n and m are independently of each other positive integers greater than 1.

[0025] According to a preferred embodiment, said perforations are arranged uniformly in rows and columns, each row and each column comprising an identical number of perforations.

[0026] In the context of the present invention, the term "uniformly" means that the distance between two adjacent perforations arranged, in said orthonormal coordinate system, at the same abscissa is identical for all the perforations of the card and that the distance between two contiguous perforations arranged on the same ordinate is identical for all the perforations of the card.

[0027] According to a preferred embodiment, the set of points comprises several subsets of points, each subset forming a third specific sign for said first sign of the same card and said first sign of another card of the same set.

[0028] In the context of the present invention, the term "specific" means: - that each first sign of a card corresponds, on another card of the same game, to a subset of points.

[0029] According to a preferred embodiment, said third specific sign of said first signs of two cards appears when the perforated area of ​​the first card is superimposed on the second sign of the second card.

[0030] According to a preferred embodiment, the third specific sign of said first signs of two cards appears when the first card completely covers the second card.

[0031] The present invention also relates to a set of parts characterized in that it comprises: a card game according to the invention, and a case completely open on its top face characterized in that its internal volume has a horizontal cross-section equivalent to that of the cards of said game. Brief description of the drawings

[0032] [Fig-1] presents an embodiment of a card according to the invention.

[0033] [Fig.2] presents an example of the use of cards according to the invention.

[0034] [Fig.3] presents an example of superimposing two maps according to the invention.

[0035] [Fig.4] presents examples of superimposing several maps according to the invention onto the same map according to the invention. Detailed description

[0036] With reference to [Fig.1], a card 1 according to the invention is preferably rectangular in shape and has a face 2 comprising a first sign 3 and a second sign 4. The other face 5 can receive a printed element for decorative or advertising purposes.

[0037] The card 1 according to the invention can be made of paper, cardboard and / or plastic. Its thickness is irrelevant and can be chosen according to the user's needs.

[0038] The dimensions of the cards 1 according to the invention are irrelevant. However, to facilitate production and distribution, the cards 1 according to the invention preferably have the standard dimensions of playing cards 1. For example, the cards according to the invention may have a length of between 11 and 12 cm and a width of between 7 and 8 cm.

[0039] The first symbol 3 can be placed anywhere on the card 1. Its position does not affect the coding system used. Advantageously, the first symbol 3 is printed on the surface of the card 1. "Symbol" means any distinctive marking such as words, letters, figures, numbers, or drawings. Preferably, said first symbol 3 is a number.

[0040] The first sign 3 is the first entry in a question. For example, the first sign 3 may be a number that corresponds to part of a mathematical operation such as multiplication or addition.

[0041] The perforated area 6 includes a series of perforations 7. These allow a part of the second sign 4 of card 1 to be seen, which is placed below another card 1 of the same set.

[0042] Each of the perforations 7 has a surface area sufficient to allow visualization of a point 8 from the set of points. Consequently, preferably said perforation 7 has a minimum surface area of ​​0.5 mm² and even more preferably of 1 mm². Advantageously, all the perforations 7 in the perforated area 6 have the same surface area.

[0043] The shape of the perforations is not important. Preferred shapes include circles, squares, and rectangles. Advantageously, all the perforations 7 in the perforated area 6 have the same shape.

[0044] The perforations 7 can be obtained by any technique known to a person skilled in the art. Among the available techniques, punching and cutting may be mentioned in particular. Punching is a preferred technique which can be carried out by an electromechanical punch press.

[0045] The perforations 7 of a given card 1 are arranged relative to each other in the same way from one card 1 to another in the same set. This latter characteristic makes it possible to distinguish the cards 1 of the same set from one another.

[0046] Each perforation zone 6 is uniquely positioned from one card 1 to the next within the same set. This position is specific to the first symbol 3 and thus reveals a unique area of ​​the second symbol 4 on the card 1 located below it. The applicant has observed that the changes in position of the perforation zone 6 from one card to the next are sufficiently subtle to be indistinguishable by an average user.

[0047] Two adjacent perforations 7 on the same line are advantageously separated by a space equivalent to n times the width of a perforation 7. Two adjacent perforations 7 at the same height are advantageously separated by a space equivalent to m times the height of a perforation 7. Thus, using all the offsets of possible, the same game can include (n+l)*(m+l) cards 1 each having the same punched area 6 positioned in a unique way.

[0048] The second sign 4 comprises a set of points 8.

[0049] Each of the points 8 has a surface area sufficient to allow its visualization through a perforation 7. Advantageously, each of the points 8 has a minimum surface area of ​​0.5 mm² and even more preferably of 1 mm². Advantageously, all the points 8 of a set of points have the same surface area.

[0050] The shape of the points 8 is of little importance. Preferred shapes include circles, squares, and rectangles. Advantageously, all the points 8 in a set of points have the same shape. Advantageously, the points 8 have the same dimensions and shape as the perforations 7.

[0051] The dots 8 are advantageously printed. The dots 8 preferably have a color that contrasts with the color of the perforated area 6 in order to improve the visibility of the dot 8 through the perforation 7.

[0052] Each set of dots comprises a series of subsets of dots 8, each forming a third sign 9 specific to said first sign 3 of the same card 1 and said first sign 3 of another card 1 from the same set. This means that, in a question-and-answer game, each subset of dots 8 corresponds to an answer in which the first sign 3 of the same card 1 will be an element of the question.

[0053] Each card 1 accumulates in the set of points 8 all the responses that can be associated with the first sign 3. This accumulation of points 8 makes the different subsets of points directly illegible and they can only be individually identified by covering them with a perforated area 6.

[0054] Preferably, the perforated area 6 and the second symbol 4 are arranged on either side of an axis dividing the card 1 into two equal parts. Even more preferably, said axis is perpendicular to the longer side of the card 1. Alternatively, said axis may be perpendicular to the shorter side of the card 1 or pass through two corners of the card 1. These arrangements allow the perforated area 6 and the second symbol 4 to overlap when two cards 1 are placed head-to-tail so as to completely cover each other.

[0055] To secure two superimposed cards 1 in position and thus facilitate the reading of the third sign 9, it may be advantageous to place them in a case open on its upper face and whose dimensions are such that its lateral edges are able to hold the cards 1 on each of their edges.

[0056] The use of a set of cards 1 according to the invention is illustrated in [Fig. 3]. The illustrated set of cards 1 is intended for teaching multiplication. It comprises nine cards 1, each containing a first symbol 3 representing a digit from 1 to 9. The first symbol 3 is repeated several times on the card in different forms in order to to allow reading regardless of the user's level and / or the position of the map.

[0057] The perforated area 6 comprises seventy-seven perforations 7, arranged in seven rows and eleven columns. Contiguous perforations 7 are separated by a distance corresponding to the dimension of two perforations 7. This arrangement allows for nine offsets from one card 1 to the next, which is sufficient to associate nine responses with each first sign 3. This is illustrated in [Fig. 4], which shows that the same card according to the invention can be used to present a variety of third signs 9.

[0058] The second sign 4 comprises 9 subsets of points 8. Each subset of points 8 forms a third sign 9 which is the answer to a multiplication of the first sign 3 with any one of the numbers 1 to 9.

[0059] The perforated area 6 and the second sign 4 are arranged on either side of the card 1, symmetrically with respect to the axis perpendicular to the long side of the card 1 and separating said card into two equivalent surfaces.

[0060] In the illustrated example, the user will randomly draw two cards 1 and must guess the result of multiplying the first 3 symbols on each card 1. Once the user has performed the calculation mentally, they will check their calculation by placing the two cards 1 upside down. By doing so, the overlap of the perforated area 6 of card 1 over the set of dots 8 of the other card 1 reveals the third symbol 9, which represents the solution to the multiplication.
