Description

[Detailed explanation of the idea] [Industrial application field]

This invention relates to an improvement of a piece arrangement educational toy having polygonal prism pieces.

[Conventional technology]

Traditionally, piece-arranged educational toys have been made by arranging rod-shaped shafts at equal intervals above and below an upright frame, and placing disc-shaped or cylindrical pieces on the shafts, as seen in number boards. A number play board with a pivoting configuration is known, and is used as a teaching tool or toy that allows young children to recognize the number of pieces by sliding the pieces left and right. However, with the above configuration, the piece itself is recognized as a numerical unit, but there is a drawback that the way in which it can be used is limited. Therefore, one possible method of use is to give a single piece multiple different indications, and create meaningful words, mathematical formulas, etc. by selecting and combining them. In this case, if different characters or numbers are displayed on the pieces at regular intervals in the circumferential direction, there is a risk that other characters or numbers adjacent to the characters or numbers displayed directly in front of the pieces may be easily misread. Therefore, by covering the top and bottom of the piece with a cover member, the display on the front of the piece can be easily read, but if the piece is unexpectedly rotated by an external force, the position of the piece will shift and it will become unreadable.

[Problem that the invention attempts to solve]

This idea was devised as a result of intensive research in view of the above circumstances, and its main challenge was not only to use pieces as units of numbers, but also to give various indications to each piece and select the appropriate number. One piece can have multiple displayed properties, and in addition, only the selection display section can be displayed in front, and the other display sections can be reliably covered, even if unexpected force is applied from outside. To provide a piece arrangement educational toy in which the rotation of the pieces is restrained by a member and the positions are maintained.

[Means to solve the problem]

In order to solve the above-mentioned problems of this invention, (a) A number of rod-shaped shafts are attached to the base in a vertically staggered manner, and each shaft is provided with a polygonal piece having a circumferential wall having a plurality of flat surfaces. (b) The flat surface of the peripheral wall of the piece is used as a display section, and different displays are displayed on the plurality of display sections; It spans the base between the rows of each axis, and covers the other display parts adjacent to the front display part, which is one oblique plane of each piece, from the front side, so that only the front display part is exposed. (c) The spacing between the cover member and the piece is set such that at least one of the cover members disposed above or below the piece comes into contact with a protrusion of the piece when the piece is rotated. We are taking technical measures such as .

[Effect]

The pieces slide along axes arranged in rows on the base and rotate in the circumferential direction. This piece is equipped with a display section consisting of a plurality of flat surfaces on its peripheral wall, and each display section has a different display written on it, so by rotating each piece in the circumferential direction, the desired display can be obtained. can be displayed in front. Then, other display sections adjacent to the front display section are covered with the cover member, so that only the front display section is exposed. A desired combination of displays is completed on the front by combining the front display sections in the same row (axis) or in each row, spaced apart from other pieces that are not used. Further, even if a force below a predetermined level is unexpectedly applied to the piece from the outside, the protrusion of the piece will not come into contact with the cover member and the piece will not rotate significantly. As a result, it is possible to reliably capture the display appearing in front of the user without misreading the display of adjacent characters, numbers, etc.

【Example】

Hereinafter, preferred embodiments of the piece arrangement educational toy according to this invention will be described based on the drawings. The piece arrangement educational toy 1 shown in Figs. 1 and 2 has a plurality of rod-shaped shafts 3, 3, ... attached vertically in parallel to a base 2, and regular hexagonal columns are attached to the shafts 3, 3, .... The body pieces 4, 4, ... are pivotally attached in a horizontally laid state, and side wall surfaces 5a to 5f are formed on the peripheral wall of the pieces 4 and become flat surfaces.
display portions 6a to 6f are formed respectively on the six display portions, and different displays 7, 7, . For example, the vertically inclined display section 6 adjacent to 6a
It has a structure in which cover members 9 and 10 are provided to cover and hide the parts b and 6f from the front side. That is, the base 2 consists of an upright rectangular frame, and a pair of leg stands 21, 21 are fixedly attached to the lower frame of the base 2, so that it can stand on its own. A plurality (10 stages in the illustrated example) of rod-shaped shafts 3, 3, . . . are fixed to the base 2 at approximately equal intervals in the vertical direction. As is clearer in FIG. 2, each of the shafts 3, 3, ... has a plurality of hollow pieces 4 each made of a regular hexagonal prism in a horizontally laid state (in the illustrated example, each shaft has 10 pieces).
) are pivotally connected. In this embodiment, this piece 4 has a weight 8 in its hollow.
It has a movable built-in. Although the weight 8 is spherical in the illustrated example, its material and shape are not particularly limited, and it may also contain granules, powder, or liquid in a sealed state. good. Piece 4
Since it is constructed in this way, a force is always exerted on the weight 8 in the vertical direction within the hollow space of the piece 4. Therefore, even if one of the side wall surfaces 5a to 5f (i.e. display parts 6a to 6f) selected by the user of the piece 4 is not rotated so as to be vertical, the piece 4
Rolling in the hollow of the side wall surface 5a at the shortest distance
Since the ridge line 5A of 5f is displaced to a vertical position, the selected side wall surface 5a can be automatically corrected to a position perpendicular to the front. Next, each of the side wall surfaces 5a to 5f of the piece 4 directly becomes the display portions 6a to 6f, and the display portions 6a to 6f become the display portions 6a to 6f.
Display consisting of letters (hiragana) on 6f 7, 7,
... has been applied. Although the type and display position of this display 7 are not particularly limited, the displays 7, 7, . . . displayed on each display section 6a to 6f of one piece 4 are different from each other. Further, all of the six display sections 6a to 6f on the piece 4 may be used, or some of them may be omitted and the remaining surfaces may be used. Furthermore, the types of indications 7, 7, ... written on the six display areas 6a to 6f in the piece 4 may be the same type (for example, hiragana) or a combination of different types (for example, hiragana and numbers). No questions asked. In addition, the display 7 displayed on one display section 6a is
As long as the content can be identified, it may be applied by combining multiple items at the same time (for example, a combination of figures and characters, colors and characters, etc.). In this embodiment, as described above, a configuration in which hiragana is written is illustrated. Furthermore, covering members 9 and 10 in a plurality of upper and lower stages are spanned over the base 2 and are located on the front side of the piece 4 between rows of shafts 3, 3, . . . . The cover members 9 and 10 in the illustrated example are made of ring-shaped elastic bodies such as rubber bands, and both ends thereof are fixed to the vertical bars on both sides of the base 2 by an appropriate means such as gluing or riveting. The portion is covered from the outside with a cover member 11 as shown in FIG. As shown in more detail in FIG. 3, the cover members 9 and 10 made of elastic bands are arranged in upper and lower inclined display parts 6b and 6 adjacent to the vertical front display part 6a of each piece 4.
The tilted display portions 6b and 6f are covered and are in contact with the front side of the frame f, and only the front display portion 6a is displayed. Therefore, no matter where a child's viewpoint is, only the display 7 on the front display section 6a can be read accurately and clearly, and the other inclined display sections 6b,
There is no possibility of misreading the display 7 of 6f. Moreover, the positional relationship between the cover member 9 and the piece 4 is
Since the cover member 9 is arranged on each piece 4 so as to be in contact with the front display part 6b when it rotates, each piece 4 is
The cover members 9 and 10 are in elastic pressure contact with the tilted display sections 6b and 6f on the front side in a vertically held position.
Rotation can be suppressed by the elastic force of. Further, when rotating the piece 4, it is sufficient to rotate the piece 4 with a force greater than the above-mentioned elastic force. This prevents the piece 4 from being inadvertently rotated by a relatively small external force. In addition, as shown in FIG. 1, an instruction mark 12 is attached to the center of the cover members 9 and 10 of each stage to designate the position of the piece 4 used on the same axis. This instruction mark 12 makes it easier to read the display 7 on the front display section 6a (or 6b to 6f) of the piece 4, and also improves the aesthetic appearance. So, now to explain how to use this piece arrangement educational toy 1, select the display written on the display part 6a of the side wall surface 5a of the piece 4 among the axes 3 of each row, and turn the display 7 facing forward. Rotate the piece 4 in the circumferential direction as shown in FIG. At this time, as described above, the weight 8 built into the piece 4 automatically adjusts the position of the selected display section 6a even if the user rotates it inaccurately. The piece 4 is the selected front display section 6a.
The upper and lower inclined display parts 6b and 6f adjacent to the front display part 6a are held vertically in the position where the cover members 9,
Covered by 10. By performing the above operations at each stage, the character strings "yo", "u", "chi", "e", and "n" can be combined as illustrated in FIG. In addition, various usages can be considered by changing the type of display 7. In the above embodiment, the piece 4 is attached to the base 2 made of a rectangular frame, but the base 2 may be formed as a part of another structure. FIG. 4 shows a different embodiment of the piece of this invention. This embodiment exemplifies a configuration in which no weight is built inside the piece. That is, in the embodiment described above, the piece itself automatically corrected its posture by the action of the weight, but if the piece is accurately positioned by the user, it is not necessary to adopt the above configuration, and the effect is the same as in the embodiment described above. It is possible to play. Since the other configurations are the same as those in the previous embodiment,
Identical configurations are given the same reference numerals and their explanations will be omitted. In the above embodiment, the shape of the piece 4 has been exemplified as a polygonal prism, but in this invention, the shape of the piece is not limited to the above-mentioned shape. It may have any other shape. Further, an additional structure may be provided such as integrally providing a plate-shaped collar formed in an appropriate shape on the wall surface in the axial direction. For example, when the piece has a built-in weight, it is sufficient that it is formed on the peripheral wall portion with at least the oblique planes facing each other at 180 degrees, and the shape of the other peripheral wall portion may be curved or any other shape. Further, in the above embodiment, the cover member is ring-shaped so that both the front and back sides can be integrally covered, but in this invention, one side or both sides are each stretched with an independent belt-shaped cover member. Good too. Further, the cover member may be detachably attached to the base, and it goes without saying that various other design changes may be made without changing the gist of the invention.

[Effect of the idea]

This invention has the above structure, so depending on the type of display, in the case of letters, a character play such as a string of letters is selected, and in the case of numbers, a string of numbers or a mathematical expression (for example, "8", "+", "5") is selected. ”, “=”, “1”, “3”, etc.) and calculations, and in the case of figures, it can be used as a teaching material or toy for young children such as picture matching and jigsaw puzzles. Moreover, by covering other display parts adjacent to the display part of the selected character string, number string, mathematical formula, etc. from the front side with the cover member, only the selected display part can be exposed. Therefore, there is no risk of misreading displays other than the selection display section, and the function as a teaching material for young children or an educational toy is greatly improved. In particular, this is convenient because the elastic force of the cover member prevents the piece from rotating inadvertently. It is a promising product that can be used in various ways depending on the type of display, combination method, etc., and is expected to develop in the future.
