Description

[Detailed Description of the Invention] This invention relates to an assembly type calculator for infants that is made of synthetic resin or the like as a main material and is capable of being assembled and disassembled.

There are a variety of conventional counters, calculators, etc. for young children, and there are even ones that have electric circuits built in as educational toys, such as ones that give an answer when you press a push button. However, there are only a few calculators that are too expensive and limit creativity, and which require users to think and assemble themselves as semi-finished products in order to enhance their creativity.These calculators were created to solve these problems.

However, the present invention was created to achieve these objectives, and will be explained below with reference to the drawings.As shown in FIG. 3 and the right side of FIG. 2. Numbers 1 to 9 are engraved intermittently in the center left (
(see FIG. 3), and the central part of the polygonal numeral body is extended vertically to form the polygonal numeral body with the supporting shaft 3 as one body.

Next, as shown in the second fixing diagram, holding holes are symmetrically drilled at even intervals in the center of the left and right side plates of the box-shaped main frames a and 9, and support shafts are provided protruding from the left and right sides of the polygonal numeral body 1. 3 into the left holding hole, insert the right side of the support shaft 3 into the right holding hole, fix the rotary knobs 4 from the outside of the right side plate so that they can rotate freely toward the outer periphery of the support shaft, and then A plurality of polygonal numerals 1 are laterally assembled inside a frame a.

In addition, the answers to addition, subtraction, multiplication, and division from 1 to 9 are imprinted on each side of the polygonal numerals on the right side.

Furthermore, as shown in the right figure of Figure 2, the four sides (left and middle code body 5,
Addition, subtraction, multiplication, and division signs are imprinted on the four sides of 5' at regular intervals of nine steps to form a code body 5, 5', and a - sign on the left side of the right code body and a polygonal numeral body on the right side. The answer numbers for addition, subtraction, multiplication, and division are stamped at uniform intervals on the bottom surface of the right-hand side and a one-symbol mark so that the answer to the right of 1 is hidden. Code body 5
2. Put on the top lid, make multiple insertion holes in the center of the front and back plates on the inside of the 100 front and back plates, and place them vertically between the numbers and the 1 code of the polygonal numerals 1. The center portions of the upper and lower surfaces of the code bodies 5, 5, 5 are extended vertically to form support shafts 6, 8 integrally with the code bodies, and the upper support shafts of the code bodies are inserted into the insertion holes of the front plate L, While inserting the lower support shaft 6 of the code bodies 5, 5, 5 into the insertion hole from the inside of the rear plate, the outer upward rotation knob 7 is fitted onto the outer periphery of the support shaft and fixed vertically so that it can rotate freely (can be rotated manually). Put the top lid on and assemble step 10.

Furthermore, Fig. 5 shows the bottom side of the right figure of Fig. 2, and shows the box-shaped main frame a, 10 in which multiple polygonal numerals 1 are installed horizontally.
When molding the box-shaped main frame, a box-shaped main frame is molded by embossing katakana, hiragana, Roman letters, etc. in alphabetical order on the bottom surface of the box (1. Top lid, 10 has a transparent congratulatory or see-through window on the top surface, Thin tube portions 12 and 13 are provided that intersect with the lower left side of the box-shaped main frames a and 9 and the lower side of the right side of the upper cover 10, and the stop pin 1
This is an assembly-type calculator for young children that can be assembled and disassembled into a hinge shape by inserting the calculator into the calculator.

If you are not going to use the assembled calculator for young children of this invention, the box-shaped main frame (main frame) a, 9 as shown in the left diagram of Figure 2.
Inside, nine polygonal numerals 1 are held by support shafts 3 and rotation knobs 4 that can be inserted into the left and right side plates, and are internally rotated manually. Numbers 1 to 9 are stamped on the left side of the box, numbers 1 to 9 are stamped on the center of each polygonal numeral body, answers to addition, subtraction, multiplication, and division are stamped on the right side, and the box-shaped main frame a.

On the inside of 10, add, subtract, multiply, and divide codes are stamped on the four sides of the code bodies 5, 5' so as to touch the middle of the numbers vertically stamped on the polygonal numeral body 1. A support shaft 8 is inserted into the insertion hole of the front and rear plates on the upper surface of the middle of the numeral of each polygonal numeral body 1, and a rotation knob 7 is inserted into the insertion hole of the rear plate from the outside onto the outer periphery of the support shaft 6 and rotated manually. Furthermore, one code is stamped on two sides of the code body 5 on the right side of Figure 2, and the answers for addition, subtraction, multiplication, and division are stamped on the other two sides at uniform intervals, and on the right side of the polygonal numeral body 1. The answers to addition, subtraction, multiplication, and division are each engraved, and they are internally rotatable manually in the same manner as the aforementioned code bodies 5 and 5' so that they are joined to the upper surface midway between the numbers in the center, and the answers to the polygonal numbers are omitted from the drawings. However, the top lid is usually placed so that the answer cannot be seen, and a sliding plate with congratulations for the player who bats first is installed on the right side of 10 so that it can be slid back and forth so that the answer can be seen smoothly.

In addition, on the upper surface of the upper cover 10, each side 2 of a polygonal numeral body 1 is provided.
A see-through window 11 is provided correspondingly.

Therefore, by supporting the rotary knob 4 on the right side of the box-shaped main frame 1, turn the rotary knob of the code body to add, subtract, multiply, and divide each polygonal numeric body 1 to 10. Time is ×
For division, I rotated the support shaft 30 on the right side by turning it in the diagonal direction, and turning the 9 knobs for example 2+2=, 4+4=answers, so I could see numbers 1 to 9 at a glance. It is designed so that people can develop their creativity while assembling and disassembling it.

FIG. 6 is an enlarged view showing the state in which the right support shaft 3 with a polygonal numeral body is fitted into the right side plate with the rotation knob 4 from the outside, and 9 is the right side plate of the box-shaped main body frame.

FIG. 7 is a schematic diagram of the box-shaped main frame a, 9 with a top cover 10 fitted thereon; 12 is a hinge-shaped thin tube 1;
3 and 12 are connected, and a stop pin 15 is inserted through the top cover to facilitate opening/closing and attachment/detachment of the top cover.

As explained above, although it looks complicated at first glance, it has a simple structure and is a semi-finished product, which allows young children to naturally learn numbers and mathematical skills by assembling and disassembling it, and it can be molded from synthetic resin. It is lightweight and easy to carry, and is effective as an educational assembling calculator for young children that doubles as a toy.It is very convenient and its practical effects are extremely novel.
