Description

Title of the invention: Card game with homogeneous perforated coding. Technical field of the invention

[0001] The present invention belongs 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] There are a number of card games based on the question / answer principle. For example, it is common to use cards with 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 a single question with a single answer. It is not possible to combine several inputs and associate them with one or more outputs. This last type of question / answer is particularly desirable for learning calculation (multiplication, addition) or 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 includes a first input in the form of a number printed on one side of the card and a perforation. Another series of cards each includes an input in the form of an operation and a printed number and a series of possible outputs.

[0005] The superposition of a card of the first series on a card of the second series makes it possible to display the solution through the perforation which reveals the appropriate exit while the other exits of the series of exits are masked by the rest of the card.

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

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

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

[0009] The present invention proposes to solve the problems listed above. More particularly, it proposes a card, usable in a question / answer game, in which: - the answers are coded and unreadable directly 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 size each having on the same face a first sign, a second sign and a perforated zone characterized in that: the perforated area comprises perforations arranged relative to each other in an identical manner 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 zone is offset from one card to another 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 play activity.

[0012] In the context of the present invention, the term “same dimension” is intended to designate elements having the same length and the same width.

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

[0014] In the context of the present invention, the term "arranged relative to each other in an identical manner from one card to another" is intended to mean first of all that all the cards in the same set comprise the same number of perforations. Furthermore, by using the barycenter of the perforation placed furthest to the bottom and left of each of the cards as the origin of an orthonormal reference frame, for each perforation of a card there is a perforation corresponding to the same position in all the cards in the game. Furthermore, from one card to another, the perforations having the same position in the said orthonormal reference frame are of the same dimension and the same shape.

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

[0016] Consequently, it is possible by superimposing all the cards of the same set, and by offsetting them relative to each other, to superimpose all the perforations so as to form channels of constant 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", "shift" are intended to mean that from one card to another the same perforation (i.e. a perforation having the same position in said orthonormal reference 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 zone have a substantially identical dimension 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 of the perforations of a card.

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

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

[0022] According to a preferred embodiment, said offset in the width direction between two cards of the same game 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 game 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" is intended to mean that the distance between two contiguous perforations arranged, in said orthonormal reference frame, at the same abscissa is identical for all the perforations of the card and that the distance between two contiguous perforations arranged at 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 sign specific to said first sign of the same card and to said first sign of another card of the same game.

[0028] In the context of the present invention, the term "specific" is intended to mean: - 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 sign specific to 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 entirely open on its upper face, characterized in that its internal volume has a horizontal section equivalent to that of the cards of said game. Brief description of the drawings

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

[0033] [Fig.2] shows an example of using cards according to the invention.

[0034] [Fig.3] shows an example of superposition of two cards according to the invention.

[0035] [Fig.4] shows examples of superposition of several cards according to the invention on the same card according to the invention. Detailed description

[0036] With reference to [Fig.l], 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 may be made of paper, cardboard and / or plastic. Its thickness is indifferent and may be chosen according to the user's needs.

[0038] The size of the cards 1 according to the invention is indifferent. However, to facilitate production and distribution, the cards 1 according to the invention preferably have the classic size 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 sign 3 can be indifferently arranged on any area of ​​the card 1. Its position does not affect the coding system used. Advantageously, the first sign 3 is printed on the surface of the card 1. By “sign” is meant any distinctive marking such as words, letters, numbers, figures, drawings. Preferably, said first sign 3 is a number.

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

[0041] The perforated area 6 comprises a series of perforations 7. These make it possible to see a part of the second sign 4 of the card 1 which is placed below another card 1 of the same game.

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

[0043] The shape of the perforations is not very important. Among the preferred shapes, we can notably cite the round, the square and the rectangle. Advantageously all the perforations 7 of the perforated zone 6 have the same shape.

[0044] The perforations 7 can be obtained by any techniques known to those 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 punching machine.

[0045] The perforations 7 of the same card 1 are arranged relative to each other in an identical manner from one card 1 to another of the same game. This latter characteristic makes it possible to make the cards 1 of the same game indistinguishable from one another.

[0046] Each perforation zone 6 is positioned uniquely from one card 1 to another of the same set. This position is specific to the first sign 3. And will therefore make it possible to reveal a unique zone of the second sign 4 of the card 1 which is placed below. The applicant was able to observe that the changes in position of the perforation zone 6 from one card to another are sufficiently discreet so that they are indistinguishable by an average user.

[0047] Two contiguous perforations 7 on the same line are advantageously separated by a space equivalent to n times the width of a perforation 7. Two contiguous perforations 7 on the same height are advantageously separated by a space equivalent to m times the height of a perforation 7. Thus, by using all the offsets possible, the same game can include (n+l)*(m+l) cards 1 each having the same perforated zone 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 sufficient surface area to allow its visualization through a perforation 7. Advantageously, each of the points 8 has a minimum surface area of ​​0.5mm2 and even more preferably of 1mm2. Advantageously, all the points 8 of a set of points have the same surface area.

[0050] The shape of the points 8 is not very important. Among the preferred shapes, we can notably cite the circle, the square and the rectangle. Advantageously all the points 8 of a set of points have the same shape. Advantageously, the points 8 have the same dimension and the same shape as the perforations 7.

[0051] The points 8 are advantageously printed. The points 8 preferably have a color which contrasts with the color of the perforated zone 6 in order to improve the visibility of the point 8 through the perforation 7.

[0052] Each set of points comprises a series of subsets of points 8 each forming a third sign 9 specific to said first sign 3 of the same card 1 and to said first sign 3 of another card 1 of the same game. This means that, in a question and answer game, each subset of points 8 corresponds to an answer of 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 answers which can be associated with the first sign 3. This accumulation of points 8 makes the different subsets of points directly illegible, as they can only be individually identified by covering them with a perforated zone 6.

[0054] Preferably, the perforated zone 6 and the second sign 4 are arranged on either side of an axis separating the card 1 into two equal parts. Even more preferably, said axis is perpendicular to the largest side of the card 1. Alternatively, said axis may be perpendicular to the smallest side of the card 1 or pass through two corners of the card 1. These arrangements make it possible to superimpose the perforated zone 6 and the second sign 4 when two cards 1 are superimposed head to tail so as to completely cover each other.

[0055] To wedge 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 dimension is such that its lateral edges are capable of holding 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 multiplications. It comprises nine cards 1, each comprising a first sign 3 representing a number from 1 to 9. The first sign 3 is repeated several times on the card in different forms in order to allow reading regardless of the user level and / or the position of the card.

[0057] The perforated area 6 comprises seventy-seven perforations 7, arranged in seven rows and eleven columns. The contiguous perforations 7 are separated by a distance corresponding to the dimension of two perforations 7. This arrangement makes it possible to make nine shifts from one card 1 to the other, 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 of a multiplication of the first sign 3 with any of the numbers 1 to 9.

[0059] The perforated zone 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 draw two cards 1 and will have to guess the result of the multiplication of the first signs 3 of each card 1. Once the calculation has been done mentally by the user, the latter will check his calculation by superimposing the two cards 1 head to tail. In doing so, the superposition of the perforated area 6 of card 1 above the set of points 8 of the other card 1 makes it possible to reveal the third sign 9 which represents the solution to the multiplication.
