Description

[Detailed Description of the Invention] [Industrial Application Field] The present invention relates to a number divider, which is an educational tool for young children for practicing number games and calculations.

[Conventional technology]

Conventionally, there is a device that uses Ohajiki as one type of the above-mentioned number divider, as shown in Fig. 3, there are left and right portions protruding from the inner surface of the lid c of a container (not shown) that accommodates a large number of Ohajiki a. Hollow pillars e, e are removably fitted and implanted into a pair of protrusions d, d (only one is shown in the figure), and the above-mentioned Ohajiki a is drilled in the center of a through hole b. It is configured so that it can be inserted into and removed from the support column e, and allows you to count the number of coins a inserted into one or both of the support columns e, e, or increase or decrease the number by comparing them. It is known to be used for the purpose of making students familiar with calculations.

[Problem that the invention attempts to solve]

However, since this number divider is constructed such that the supports e and e into which the Ohajiki a is inserted stand upright on the inner surface of the lid c, in order to perform the number games and calculations described above, the lid c is Not only does it have to be removed from the box (not shown) of the container and turned upside down, but this also causes the side plate c' of the lid c to get in the way when inserting and removing the ohajiki a.
Because it is necessary to fit into the protrusion d, a hollow shaft is used, so it is relatively thick, and accordingly, the through-hole b of the headpiece a also had to be formed with a large diameter.

[Means for solving problems]

The present invention provides a number divider that solves the above-mentioned problems, and is capable of accommodating a large number of ohajiki with a through hole in the center. A box body having a generally rectangular shape in plan view, which is provided with a baffle plate that extends to the other long side plate and does not reach the other long side plate, and has a long hole bored in the longitudinal center of the other long side plate through which a coin can pass; A lid that is removably attached to the opening and is transparent on half of its length in the longitudinal direction, and a tapered inner circumferential surface that is recessed in the bottom outer surface of the lid near one long side and expands in diameter outward. A fitting that can be inserted into a pair of left and right fitting holes and a through-hole of the Ohajiki, and has a required number of small protrusions extending in the axial direction and having a tapered shape corresponding to the fitting holes at one end. The structure includes a support column having an end portion.

[Effect]

According to the present invention, since the support is installed upright on the outer surface of the lid, it is possible to play games with the lid attached to the box, and the side plates of the lid can be It won't get in the way. Further, the support can be shaped like a thin rod, and the small protrusion provided at one end has the function of maintaining a securely fixed state with the fitting hole of the lid, and the fitting part has a tapered shape. It is also easy to remove. In addition, since the fitting hole of the lid body is close to one long side, when inserting and removing the hajiki to the post fixed to the fitting hole, position the post on the front side and perform the insertion/extraction operation. It is easy to do, and the fitting hole does not get in the way when counting the number of ohajiki that are inserted through the long hole in the box body and are divided to the left and right by the baffle plate inside the box body by looking through the transparent half of the lid body. do not become.

〔Example〕

Next, an embodiment of the number divider of the present invention will be described based on the drawings.

In Fig. 1, reference numeral 1 indicates a cherry blossom-shaped resin Ohajiki with a through hole 2 in the center, and 3 indicates the Ohajiki 1.
A box body 4 made of opaque material that accommodates a large number of
The container has a generally rectangular parallelepiped shape and includes a lid 9 made of a transparent material that is removably attached to an opening 5 of the box 4, and one long side plate 6a is located in the center of the former box 4 in the longitudinal direction.
A baffle plate 7 is integrally formed upright on the other side, and a long hole 8 into which an ohajiki 1 can be inserted is bored in a portion of the other long side plate 6b corresponding to the baffle plate 7. , on the bottom outer surface 10 of the latter lid body 9,
The inner peripheral surface 11' is located close to the long side of one side.
A pair of tapered fitting holes 11, 11 whose diameter expands upward is recessed at appropriate intervals in the left and right (longitudinal direction), and the bottomed cylindrical portion forming the fitting holes 11. 12 protrudes from the inner surface 10' of the lid 9, and one half of the inner surface 10' bordering on the center in the longitudinal direction is provided with a finely uneven surface 13, making it semi-transparent. 14, 14 are the fitting holes 11, 11
A thin rod-shaped resin support that is removably installed in the
The length is set such that a large number of Ohajiki 1... can be loosely inserted into the through holes 2... in a state where they are overlapped in the axial direction, and the fitting end 15 of the support column 14 is enlarged in Fig. 2. As shown, the outer circumferential surface 15' has a tapered shape corresponding to the inner circumferential surface 11' of the fitting hole 11, and a plurality of small protrusions 16 are formed protrudingly spaced equidistantly in the circumferential direction.

That is, since the above-mentioned number divider is configured such that the pillars 14, 14 are erected on the outer surface 10 of the lid body 9,
As described in the above [Function] section, the lid 9 can be inserted into and removed from the supports 14, 14 with the lid 9 mounted on the box 4.
The side plate 9', etc. of the
If the supports 14, 14 are placed on the front side, the above-mentioned insertion/extraction operation becomes easier. In addition, the small protrusions 16 provided on the fitting end 15 of the strut 14 are the inner circumferential surface 1 of the fitting hole 11.
1' to help maintain a reliable standing state of the support column 14 with respect to the lid 9, and the fitting hole inner circumferential surface 11' and the fitting end outer circumferential surface 15' are tapered upward. Since the diameter is expanded, the support column 14 can be easily removed.

In addition to the above-mentioned usage, this number divider can also be used for
After combining the box body 4 and the lid body 9 and placing the container 3 with the long hole 8 facing upward,
An arbitrary number of oysters 1 are placed and dropped, and the number of oysters 1 are divided left and right by the baffle plate 7 in the container 3, and more specifically, the number of oysters 1 distributed on the transparent half side of the lid body 9 can be seen through. with a number,
It can also be used to estimate the remaining number that cannot be seen through the uneven surface 13. At that time, the pillar 14
Since the fitting hole 11 is located near the upper or lower edge of the lid body 9, the number of visible openings 1 is limited by the presence of the fitting hole 11 and the bottomed cylindrical portion 12 around it. It never becomes difficult to count.

[Effect of idea]

As described above, the number divider of the present invention allows various number games to be played with the lid body and box body combined together, and the two do not come apart.

The side plate of the lid does not get in the way when in use.

The upright state of the support column is maintained reliably, and its removal is also easy.

The pillars can be made relatively thin.

Since the fitting hole for the column provided in the lid body is located close to the long side of the lid body, the column can be positioned in front of you and you can easily insert and remove the column. The fitting hole does not get in the way when counting the number through the transparent half of the lid.

It produces excellent effects.
