Summary of the Invention

Problems to be Solved by the Invention

[0004] In recent years, there has been a demand for providing card toys that can also be used for learning using Chinese characters.

[0005] The present invention has been made in view of such circumstances, and an object thereof is to provide a card toy that can also be used for learning using Chinese characters.

Means for Solving the Problems

[0006] In order to achieve the above object, the card toy of the present invention is a card toy having a plurality of cards, wherein the cards are characterized in that a plurality of Chinese characters are described thereon.

[0007] According to the present invention, since a plurality of Chinese characters are described on the cards, a card toy that can also be used for learning using Chinese characters can be provided.

[0008] In the plurality of cards, if any one of the cards has at least one kanji character in common with any other card, then it is possible to learn kanji while searching for which kanji character is common to any one card and any other card.

[0009] The inside of the card has a predetermined shaped portion with a plurality of cuts of a predetermined shape, and a continuous portion is formed between adjacent cut portions, connecting the predetermined shaped portion and the surrounding portion. By pressing the predetermined shaped portion, the continuous portion can be broken, separating the predetermined shaped portion from the surrounding portion and forming a hole in the predetermined shaped portion. More specifically, the central part of the card has three arc-shaped notches forming a circular portion, and three continuous portions are formed between adjacent notches, connecting the circular portion and the peripheral portion. By pressing the circular portion, the continuous portions can be broken, separating the circular portion from the peripheral portion and forming a hole in the central part.

[0010] In other words, if there are two arc-shaped notches and two continuous sections, there is a risk that the circular section may separate from the surrounding section due to vibrations such as those during product transport, without any pressure being applied to the circular section. If there are four arc-shaped notches and four continuous sections, there is a risk that the pressing force required to break the continuous section may become excessively large.

[0011] In other words, in the card toy of the present invention, if there are three arc-shaped notches and three continuous sections, the card will not separate due to vibrations such as those during product transportation, and the pressing force will not become excessively large, allowing for an appropriate pressing force to break the continuous section.

[0012] The pressing force applied to the circular portion to break the continuous portion can be a predetermined value, which can be 2.5N to 6N.

[0013] In other words, the card toy of the present invention is intended for elementary school students in grades 1 through 3 who are receiving kanji education. By setting the pressing force of the pressing device to 2.5N to 6N, the average elementary school student in grades 1 through 3 can break the cards with a slightly greater pressing force than usual, which is expected to contribute to the intellectual and physical development of the target elementary school students in grades 1 through 3, as it provides moderate exercise for their fingers.

[0014] The predetermined value is the measured value of the pressing force when the continuous portion is broken by pressing the circular portion with a predetermined pressing device, the pressing device having a shaft-shaped body for pressing the circular portion, an operating part for operating the shaft-shaped body to move in the axial direction, a mounting part for placing the card, and a measuring part for measuring the measured value of the pressing force, the tip of the shaft-shaped body is provided so as to be covered by an elastic body, the mounting part is plate-shaped and has a hole that is larger in size than the outer diameter of the circular portion of the card, and the measured value of the pressing force by the measuring part is, The card is placed on the aforementioned mounting unit such that the circumferential portion of the circular part of the card is located inside the hole of the aforementioned mounting unit, and the area outside the circular part of the card is supported by the area outside the hole of the aforementioned mounting unit. The shaft-shaped body is then operated by the operating unit to move at a predetermined speed in the axial direction, and the tip of the elastic body is pressed against a predetermined pressing position on the circular part. The measured value of the pressing force when the state in which all three continuous parts of the unit are continuous, with the circular part and the peripheral part being continuous, is broken, can be set to the predetermined value.

[0015] By using rubber for the elastic body, and more specifically, by using urethane rubber, it is possible to create a pressing device that simulates the elasticity and feel of a human finger, and the measured pressing force of the pressing device can be made to approximate the pressing force when a person presses with their finger.

[0016] By setting the shear hardness of the elastic body to 40-60, it is possible to further simulate the elasticity and feel of a human finger.

[0017] The predetermined pressing position of the circular portion is a position between the circular portion and the one continuous portion to be broken from the center of the circular portion, and the shaft center of the shaft body can be pressed against the circular portion so as to come to this position.

[0018] The pressing position can be a radial position from the center of the circular portion to the one continuous portion.

[0019] The ratio of the distance from the pressing position to the one continuous portion to the distance from the pressing position to the center of the circular portion can be 1.0 to 1.5.

[0020] The predetermined speed of the shaft body can be 1.0 to 2.0 mm / s.

Advantages of the Invention

[0021] According to the present invention, it is possible to provide a card toy that can also be used for learning using Chinese characters.

[0024] Referring to Figures 1 to 3, the outline of the card toy 1 of the present invention will be described. The card toy 1 is made of paper and has multiple cards 10. The card toy 1 has, for example, 55 cards 10 and can be used to play various card games.

[0025] Card 10 has an outline that is roughly square. The corners 10c of card 10 are curved and protrude outwards, giving them a rounded shape. The vertical dimension A and horizontal dimension B of card 10 are 5-10cm, more specifically 6-8cm, and more specifically 7cm, and the weight is 0.5-2.5g, more specifically 1.0-2.0g, and more specifically 1.5g. Card 10 is made of paper, and the front surface 10' and back surface 10'' are embossed.

[0026] Card 10 has a serial number 10b and several Chinese characters 10a printed on its front 10' and back 10''.

[0027] The serial number 10b is described on both the front surface 10' and the back surface 10'' of the central part 11 of the card 1. The serial number 10b on the front surface 10' is in Arabic numerals, and the serial number 10b on the back surface 10'' is in Chinese numerals. When the number of cards 10 is 55, the serial number 10b ranges from 1 to 55. On the first card 10, "1" is described in the central part 11 of the front surface 10', and "one" is described in the central part 11 of the back surface 10'. Also, on the 55th card 10, "55" is described in the central part 11 of the front surface 10', and "fifty-five" is described vertically in the central part 11 of the back surface 10'.

[0028] A plurality of Chinese characters 10a are described on both the front surface 10' and the back surface 10'' of the peripheral part 12 of the card 10.

[0029] On the front surface 10' of the card 10, the Chinese character 10a of 3 is described on the lower side. Also, on the back surface 10'' of the card 10, the Chinese character 10a of 8 is described. The Chinese characters 10a of 8 on the back surface 10'' are described in a radial pattern and at equal intervals of 45°. The Chinese characters 10a of 8 on the back surface 10'' have different colors from each other.

[0030] On the back surface 10'' side of any one card 10A and another card 10B among the plurality of cards 10, as shown in FIG. 4, at least one Chinese character 10a' among the plurality of, more specifically, eight Chinese characters 10a is common to each other. The Chinese characters 10a described on the card 10 are the Chinese characters of the first to third grades in the Chinese character allocation table by grade in the elementary school learning guidance syllabus.

[0031] In the inner central part 11 of the card 10, a predetermined shape part 13 provided with a plurality of cut parts 15 of a predetermined shape is formed. Between adjacent cut parts 15, a continuous part 14 that connects the predetermined shape part 13 and the peripheral part 12 is formed. By pressing the predetermined shape part 13, the continuous part 14 can be broken to separate the predetermined shape part 13 from the peripheral part 12, and a hole 13' can be formed in the predetermined shape part 13. More specifically, the central part 11 of the card 10 is provided with three arc-shaped linear notches 15. These three arc-shaped linear notches 15 form a circular part 13 in the central part 11 of the card 10. Between the ends 15a of adjacent notches 15, three continuous parts 14 are formed, connecting the circular part 13 and the peripheral part 12. Therefore, as shown in Figure 5, by pressing the circular part 13, the continuous parts 14 can be broken, separating the circular part 13 from the peripheral part 12 and forming a hole 13' in the central part.

[0032] In other words, if there are two arc-shaped notches 15 and two continuous sections 14, there is a risk that the circular section 13 may separate from the surrounding section 12 due to vibrations such as those during product transport, without any pressure being applied to the circular section 13. If there are four arc-shaped notches 12 and four continuous sections 14, there is a risk that the pressing force required to break the continuous section 14 may become excessively large.

[0033] In other words, in the card toy 1 of the present invention, if there are three arc-shaped notches 15 and three continuous sections 14, the card will not separate due to vibrations such as those during product transportation, and the pressing force will not become excessively large, allowing for an appropriate pressing force to break the continuous section 14.

[0034] Furthermore, the continuous section 14 has a width dimension C of 0.5 to 1.5 mm, more specifically 0.7 to 1.3 mm, and more specifically 1 mm, and a thickness D of 0.25 to 0.4 mm, more specifically 0.3 to 0.35 mm, and more specifically 0.33 mm. The continuous section 14 of 3 is formed at equal intervals of 120°. In addition, the central section 11 of the card 10, more specifically the circular section 13, has a diameter E of 2 to 3 cm, more specifically 2.2 to 2.8 cm, and more specifically 2.5 cm.

[0035] With the card toy 1 configured in this way, you can find the common kanji character 10a' on the back side 10'' of any one card 10A and another card 10B, and hold up the common kanji character 10a' through the hole 13'' separated by the circular part 13, or throw the cards 10 like shuriken and play a game similar to ring toss.

[0036] Here, the pressing force applied to the circular portion 13 to break the continuous portion 14 is a predetermined value. More specifically, the predetermined value is between 2.5N and 6N.

[0037] In other words, the card toy 1 of the present invention is intended for use by elementary school students in grades 1 through 3. By setting the pressing force of the pressing device 100 to 2.5N to 6N, the average elementary school student in grades 1 through 3 can break the card with a slightly greater pressing force than usual, which is expected to contribute to the development of the intellectual and physical abilities of the target elementary school students in grades 1 through 3, such as providing moderate exercise for their fingers.

[0038] The predetermined value is the measured pressure when the continuous section 14 is broken by pressing the circular section 13 with the predetermined pressing device 100 shown in Figures 6 and 7. This pressure is such that an average elementary school student in grades 1 through 3 can break it with a pressure slightly greater than the normal pressure.

[0039] The pressing device 100 for measuring this pressing force has the following configuration.

[0040] In other words, as shown in Figures 6 and 7, the pressing device 100 includes a shaft-shaped body 101 for pressing the circular portion 13, an operating part 102 for operating the shaft-shaped body 101 to move in the axial direction (up and down direction), a mounting part 103 for placing the card 10, and a measuring part 104 for measuring the measured value of the pressing force. The tip portion 101a of the shaft-shaped body 101 is covered by an elastic body 101b. The elastic body 101b is made of rubber, and the rubber is urethane rubber.

[0041] The shear hardness of the elastic body 101b is set to be 40-60, more specifically 45-55, and even more specifically 50. The mounting portion 103 is plate-shaped and has a hole 103a with a dimension F that is larger than the outer diameter dimension E of the circular portion 13 of the card 10.

[0042] In other words, the measurement value of the pressing force by the measuring unit 104 can be measured as follows.

[0043] First, as shown in Figure 8, the card 10 is placed on the mounting section 103 such that the circumferential portion 13a of the circular part 13 of the card 10 is located inside the hole 103a of the mounting section 103.

[0044] Then, as shown in Figure 9, with the outer area of ​​the circular portion 13 of the card 10, i.e., the peripheral portion 12, supported by the outer area 103a' of the hole 103a of the mounting portion 103, the operating portion 102 is used to operate the shaft-shaped body 101 so that it moves in the axial direction (up and down direction) at a predetermined speed, and the tip portion 101a, which is provided with the elastic body 101b, is pressed against the predetermined pressing position X of the circular portion 13.

[0045] This results in a state where all three continuous sections 14 are connected to the circular section 13 and the peripheral section 12, but only one continuous section 14 is broken. The measured value of the pressing force when all three continuous sections 14 are connected to the circular section 13 and the peripheral section 12, but only one continuous section 14 is broken, is set to a predetermined value.

[0046] The predetermined pressing position X of the circular portion 13 is the position X between the center O of the circular portion 13 and the continuous portion 14 to be broken, and the shaft body 101 is pressed against the circular portion 13 so that the axial center 101' of the shaft body 101 is at the pressing position X.

[0047] The pressing position X is defined as the position X in the radial direction R from the center O of the circular portion 13 to the first continuous portion 14. The ratio G of the distance Z (7 cm) from the pressing position X to the first continuous portion 13 to the distance Y (5.5 cm) from the pressing position X to the center O of the circular portion 13, as shown in Equation 1, is set to 1.0 to 1.5, more specifically to 1.1 to 1.4, and even more specifically to 1.27. [Mathematics 1] G=Z / Y

[0048] Furthermore, the predetermined speed of the axial body 101, which is movable in the axial direction (up and down direction) by the operating unit 102, is set to 1.0 to 2.0 mm / s.

[0049] The predetermined speed of the shaft-shaped body 101, which is movable in the axial direction (up and down direction) by the operating unit 102, is set to 1.0 to 2.0 m / s, more specifically to 1.2 to 1.8 m / s, and more specifically to 1.5 mm / s. The outer diameter of the tip portion 101a of the shaft-shaped body 101, to which the elastic body 101b is provided, is set to 5 to 15 mm, more specifically to 7 to 13 mm, and more specifically to 10 mm.

[0050] The measured pressing force when all three continuous sections 14, which were connected to the circular section 13 and the peripheral section 12, were broken is shown in Figures 10 to 12. As shown in these figures, the measured pressing force was 2.5 to 6 N, the average value was 3.96 N, the standard deviation was 0.58, and the time from when the tip 101a of the shaft-shaped body 101 contacted the surface of the circular section 13 of the card 10 until it broke was 6 seconds.

[0051] As described above, according to the present invention, since the card 10 has multiple kanji characters 10a written on it, it is possible to provide a card toy 1 that can also be used for learning using the kanji characters 10a.

[0052] Furthermore, in any one card 10 and any other card 10 among the multiple kanji 10a, at least one kanji 10a' is common to both, allowing learners to study kanji 10a while searching for the kanji 10a' that is common to both cards 10 and any other card 10.

[0053] Furthermore, Card 10 has an outline that is roughly square, with vertical dimension A and horizontal dimension B being 5-10 cm, more specifically 6-8 cm, and even more specifically 7 cm. This means that the dimensions of Card 10 are set to be slightly larger than the average hand size of a first to third grader, making it deliberately difficult to handle. In other words, by deliberately making it difficult to handle, it is expected that it will provide good hand and finger exercise for the target audience of first to third graders, and will contribute to the growth of their intellectual and physical abilities.

[0054] Furthermore, the diameter E of the circular part 13 of card 10 is set to 2-3 cm, more specifically 2.2-2.8 cm, and more specifically 2.5 cm. When the circular part 13 is separated to form a hole 13', the dimensions of the hole 13' are suitable for elementary school students in grades 1 through 3 to play by inserting their fingers into the hole 13'.

[0055] Furthermore, by making the elastic body 101b provided at the tip 101a of the shaft 101 of the pressing device 100 out of rubber, and more specifically, out of urethane rubber, the pressing device 100 can be made to simulate the elasticity and feel of a human finger, and the measured pressing force of the pressing device 100 can be made to be closer to the pressing force when a person presses with their finger.

[0056] Furthermore, by setting the shear hardness of the elastic body 101b to 40-60, it is possible to further simulate the elasticity and feel of a human finger.

[0057] In the above-described embodiment, the predetermined value is set to 2.5N to 6N, and is the measured value of the pressing force when the continuous portion 14 is broken by pressing the circular portion 13 with the pressing device 100. However, the measured value of the pressing force may change when pressing with a pressing device of a different configuration.

[0058] In other words, even if the measured pressure is 2.5N to 6N when the circular portion 13 is pressed by another pressing device 100 or other equipment, causing all three continuous portions 14 to break from a state where the circular portion 13 and the peripheral portion 12 are continuous, if the measured pressure is 2.5N to 6N when the circular portion 13 is pressed by a pressing device 100 having the same configuration as the pressing device 100 of this embodiment in the same manner, causing all three continuous portions 14 to break from a state where the circular portion 13 and the peripheral portion 12 are continuous, it is interpreted that this falls within the scope of the claims of the present invention.

[0059] It should be noted that the present invention is not limited to the embodiments described above and can be modified and applied in various ways.

[0060] For example, in the embodiment described above, the central part 11 of the card 10 is provided with three arc-shaped notches 15 to form a circular part 13, and three continuous parts 14 are formed between adjacent notches 15 to connect the circular part 13 and the peripheral part 12. By pressing the circular part 13, the continuous parts 14 are broken, separating the circular part 13 from the peripheral part 12 and forming a hole 13' in the central part 11. However, the embodiment is not limited to "the central part 11 of the card 10," "the arc-shaped notches 15," and "the circular part 13."

[0061] In other words, the "central part 11 of card 10" can be any part of the "inside of card 10," and may be the edge or corner of card 10. Also, the "arc-shaped cutout 15" can be any cutout 15 of a predetermined shape, and may be straight or other curved. Furthermore, the "circular part 13" can be any part of a predetermined shape, and may be elliptical, rectangular, star-shaped, etc.

[0062] In other words, as described above, a predetermined shaped portion 13 is formed in the central portion 11 on the inside of the card 10, with a plurality of cut portions 15 of a predetermined shape provided therein. A continuous portion 14 is formed between adjacent cut portions 15, connecting the predetermined shaped portion 13 and the peripheral portion 12. By pressing the predetermined shaped portion 13, the continuous portion 14 is broken, separating the predetermined shaped portion 13 from the peripheral portion 12 and forming a hole 13' in the predetermined shaped portion 13.

[0063] However, it goes without saying that a more preferable embodiment is one in which the central portion 11 of the card 10 is provided with three arc-shaped notches 15 to form a circular portion 13, and three continuous portions 14 are formed between adjacent notches 15 to connect the circular portion 13 and the peripheral portion 12, and the continuous portions 14 are broken by pressing the circular portion 13 to separate the circular portion 13 from the peripheral portion 12, thereby forming a hole 13' in the central portion 11.
