BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a math instructional toy that allows children and the like to learn addition and subtraction while playing.

[0002]

2. Description of the Related Art Conventionally, as the arithmetic toys described above, Japanese Utility Model Publication No. 54-40136 and Japanese Utility Model Publication No. 54-4 are used.
The one disclosed in Japanese Patent No. 2759 is known.

[0003]

The conventional arithmetic toys described above have a problem that a child or the like can remember addition while playing, but cannot remember subtraction. An object of the present invention is to provide an arithmetic learning toy having a simpler structure than a conventional one, in which a child or the like can learn both addition and subtraction while playing.

[0004]

In order to achieve the above-mentioned object, the math instructional toy of the present invention has button fitting holes 12 at the top and vertically long arm actuating holes 13 and 14 on both left and right sides. A hollow toy main body 11 having a window 16 and a small window 18, a window hole opening / closing body 17 for opening / closing the small window 18 of the main body 11 and the window hole opening / closing body 17 provided in the button fitting hole 12 of the main body 11.
Push button 31 to open the interlock by pushing
Then, an analog display 27 and a digital numeral 28 are displayed on the outer peripheral surface, and the analog display 27 and the digital numeral 28 are rotatably supported in the main body 11 so as to be sequentially exposed to the large window 16 and the small window 18, respectively. A vertically rotatable left side projecting to the outside of the main body 11 through a cylinder 25 and an arm operating hole 13 on the left side of the main body and an arm operating hole 14 on the right side of the main body that are pivotally supported by the left and right brackets 23 and 24 in the main body 11. Arm 33
And the right arm 34 and the pushing operation of the right arm 34 causes the rotary cylinder 25 to perform an adding operation by one pitch, and the pushing operation of the left arm 33 causes the rotary cylinder 2 to move.
The ratchet type interlocking mechanism 40 for subtracting 5 by 1 pitch, and the ratchet pawls of the interlocking mechanism 40 are disengaged, and the rotary cylinder 25 is returned so that each analog display 27 and digital number 28 return to zero. The reset mechanism 70 for operating is provided.

[0005]

In the arithmetic learning toy having the above-described structure, the rotary cylinder 25 is rotated by one pitch in the adding direction each time the right arm 34 is pushed down, and the figure corresponding to the number of pushes of the right arm 34 is displayed. When the analog display 27 appears on the large window 16 and the push button 31 on the top of the main body is pressed, the same number of digital numbers 28 as the number of the displayed figures appears on the small window 18, so that children and others can add while playing interestingly. You can remember

In addition, in the arithmetic training toy of the present invention, when the left arm 33 is pushed down during the addition operation or at the end of the addition operation, the rotary cylinder 25 moves in the subtraction direction every time the left arm 33 is pushed down once. By turning back one pitch at a time, the analog display 27 such as a figure displayed on the large window 18 is sequentially returned and subtracted by the number corresponding to the number of pushes each time, and the push button 31 on the top of the main body is pushed. Since the same number of digital numbers 28 as the subtracted numbers appear in the small window 18, a child or the like can remember the subtraction while playing interestingly.

Further, when the reset mechanism 70 is operated during the addition operation and the subtraction operation as described above, each analog display 27 and the digital number 28 are returned to 0, and the same addition and subtraction as described above are repeated. You can practice.

2, a pin movable plate 73 that has a pin pushing end portion that can come in contact with and separate from the reset pin 72, and that can slide back and forth in a central groove in the main body as shown in FIG. The movable plate pressing operation portion 75 is provided at the end portion and protrudes rearward of the main body through the rear end hole 74 of the main body 11.

When the pin movable plate 73 is pushed forward in the addition operation and the subtraction operation (state shown in FIG. 3) as described above, the pin push end of the pin movable plate 73 becomes the reset pin 72. Upon contact, the second ratchet lever 44 is rotated so that the second ratchet pawl 62 engages and disengages from between the operating pins 34, and the concave engaging portion 61 engages and disengages from the rotary connecting pin 57. Outward escape rotation of the first ratchet lever 42 as shown in FIG. 4 due to rotation of the second ratchet lever 44 (at this time, the second rotation lever 43 is in the engagement / disengagement state as shown in FIG. 3). Then, the first ratchet pawl 51 of the first ratchet lever 42 comes into engagement and disengagement from between the operation pins 34.

That is, when the pin movable plate 73 is pushed forward in the state shown in FIG. 3, the first ratchet pawl 51 is moved.
Then, the second ratchet pawl 62 and the reversal stopper pawl 56 are all disengaged from the operating pin 35, and the rotary cylinder 25 is analog-displayed by the accumulated power of the reversing power spring 26 that is wound during the addition operation. And the digital number 28 is returned to 0.
When the rotary cylinder 25 is returned to the zero point, the projecting pin 35a at the lower end of the cylinder has the base stopper projection 7 shown in FIGS.
It is regulated by abutting on 6.

[Effects of the Invention] Since the arithmetic toy learning toy of the present invention has the construction described in the scope of claims for utility model registration,
Each time the right arm 34 is pushed down once, the rotary cylinder 25 rotates by one pitch in the adding direction, and the analog display 27 such as a figure corresponding to the number of pushes of the right arm 34 appears in the large window 16. When the push button 31 on the top of the main body is pressed, the same number of digital numbers 28 as the number of figures shown appears on the small window 18, so that a child or the like can enjoy the addition while playing interestingly.

In the arithmetic toy of the present invention, when the left arm 33 is pushed down during the addition operation or at the end of the addition operation, the rotary cylinder 25 moves in the subtraction direction every time the left arm 33 is pushed down once. By turning back one pitch at a time, the analog display 27 such as a figure displayed on the large window 18 is sequentially returned and subtracted by the number corresponding to the number of pushes each time, and the push button 31 on the top of the main body is pushed. Since the same number of digital numbers 28 as the subtracted numbers appear in the small window 18, a child or the like can remember the subtraction while playing interestingly.

Further, when the reset mechanism 70 is operated during the addition operation and the subtraction operation as described above, each analog display 27 and the digital numeral 28 are returned to 0, and the same addition and subtraction as described above are repeated. You can practice.
