Description

[Detailed description of the invention] The present invention relates to an addition toy in which a rotary wheel is rotated intermittently and numbers are displayed at positions corresponding to the rotation of the rotary wheel in increments. This invention relates to an addition toy that does not rotate more than a notch.

The present applicant first proposed the application in 1983-995 in order to incorporate the learning of arithmetic into play and improve academic ability while having fun.
As No. 25, he proposed an idea regarding addition toys.

Such a device rotatably supports a plurality of pin wheels displaying numbers to be added on the outer circumferential surface and one pin wheel displaying the resultant number on the outer circumferential surface, and controls the movement of the intermittent feed member. When the rotating wheel that displays the number to be added is rotated in intermittently, the rotating wheel that displays the answer number added by the same number of rotations as the number of rotations in intermittently is also rotated in intermittently, and each number to be added is displayed. The rotating wheels whose answers are displayed intermittently rotate by the total number of intermittent rotations of the rotating wheels, and numbers are displayed on the outer circumferential surface of each rotating wheel for each angle corresponding to one increment of rotation. By attaching it at a predetermined position, the numbers to be added and the result of the addition are made to face the display window.

The problems involved in the above prior art are as follows.

That is, since addition toys are generally used by young children, they may hit the operating buttons with all their might without saving force when operating the operating buttons.

In such a case, the pushing pawl of the intermittent feed member may not feed the pin by one increment, but may feed the pin by two or more increments.

As a result, the rotating wheel that displayed the number to be added stopped rotating for two increments, but the rotating wheel that displayed the answer to add did not rotate for one increment, or conversely, it displayed the answer that added. The rotating wheel will rotate more than the predetermined value.

In this case, an incorrect answer will appear on the display window, and there is a risk that the learning effect will be counterproductive.

In view of the above-mentioned problems, the present inventor developed the present invention in order to effectively solve the problem. A rotary wheel displaying a numeric value that is the summation answer, and a rotary wheel displaying a numeric value to be added. and a rotating wheel displaying an answer are provided so as to rotate intermittently at the same time, and a regulating pawl is provided on the feed member to prevent the rotating wheel from rotating intermittently by more than two increments at a time, thereby preventing rough operation. To provide an addition toy that can always display a correct answer without displaying an incorrect answer even when the answer is incorrect.

A preferred embodiment of the present invention will be described in detail below with reference to the accompanying drawings.

Said push-up member 44. Case bottom plate 18 near 46
Two brackets 85 and 86 are provided spaced apart from each other on the top, the proximal end of a striking member 87 is pivotally attached to one bracket 85 as shown in FIG. As shown in Figure 3, the bell 88 is firmly attached.

The striking member 87 is elastically supported from below by a spring 89 so that the striking part of the striking member 87 is located slightly above the bell 88.

A projecting piece 90 extending above the plate parts 49, 59 of the push-up members 44, 46 is attached to the middle part of the striking member 87, and when the push-up members 44, 46 are moved upward by the rotation of the arm rods 33, 37, The striking member 87 rotates upward about the pivot portion, and when the push-up member descends, it rotates downward, and its momentum strikes the bell 88.

Further, a hidden plate 8 is provided inside the display section 4 formed in the case 1 so as to be able to appear and disappear at will.

That is, the hidden plate 8 is elastically biased upward by a spring fixed to the inner surface of the case 1, and when the lower end of the hidden plate 8 is connected to a connecting rod that is linked to the push button 16, and the push button 16 is pushed down, The hidden plate 8 moves downward against the elastic force of the spring, so that the number 7a corresponding to the answer displayed on the outer peripheral surface of the rotary wheel 7 appears on the display section 4.

FIG. 6 shows a mechanism for preventing the rotating wheels 5 and 6 from rotating at the same time, in which a bracket is provided on the bottom plate 18 located between the upright piece 34 of the arm rod 33 and the upright piece 38 of the arm rod 37. A swinging member 91 having a substantially semicircular side surface is attached to this bracket.
It is centrally connected.

The upper end surface of this swinging member 91 has push buttons 14 and 15, respectively.
When facing the lower end of the button, when one push button, for example push button 14, is pressed down, it swings in the direction of the arrow in the figure, and when the other push button 15 is pushed down, it swings in the opposite direction. However, both pushbuttons 14 and 15 can only be pressed down at the same time.

That is, if the pushbuttons 14 and 15 can be pressed at the same time, the rotary wheel 7 will not rotate by the total number of intermittent rotations of the rotary wheels 5 and 6, but will only rotate by the number of times that are pressed at the same time. The incorrect answer will be displayed, so press button 14. 15 is prevented from being pressed down at the same time.

゛The operation of the addition and toy consisting of the above structure will be explained in detail below.

First, the display sections 2, 3. Turn each rotating wheel 5, 6, at a position where all the numbers facing 4 are "0".
Set 7.

Then, when the push button 14 is pressed down, this 14 moves to the armrest 3.
3, the arm rod 33 is rotated clockwise about the shaft 22.

Then, the lower end of the elongated hole 36 formed in the arm rod 33 comes into contact with the rod-shaped member 42, causing the side rod 40 to rotate clockwise against the spring 84, thereby locking the pin 26 and the pawl 74. Release.

At the same time, the push-up member 44 pivotally attached to the tip 43 of the arm rod 33 is lifted upward against the spring 94, and the push-up claws 52, 54 formed on the feed arms 50, 51 of this push-up member are lifted up against the spring 94. contacts the pins 26 of the rotary wheels 5 and 7, respectively, to push them up and rotate them.

Incidentally, at this time, the locking state between the stop claw 76 of the bent arm 73 and the rotary wheel 7 is released.

This upward rotation causes the rotary wheels 5 and 7 to rotate intermittently for one minute.

Here, as described above, the regulating claws 53 and 55 are formed below the pushing claws 52 and 54, so even if the push button 14 is pushed down strongly, the pin 26 will come into contact with the lower end of the regulating claws 53 and 55, and further Since rotation is regulated, the rotating wheels 5 and 7 will not rotate intermittently by more than two increments due to a single depression of the push button 14.

Also, the spring 3 provided on the bulge 35 of the arm rod 33
5a comes into sliding contact with the outer surface of the rotary wheel 5 when the arm rod 33 swings, so that moderate rotation is ensured, and this also prevents intermittent rotation of more than two increments.

Further, since the spring 73a provided on the bent arm 73 that restricts the return rotation of the rotary wheel 7 is also in sliding contact with the outer side of the rotary wheel 7 with moderation, rotation of the rotary wheel 7 by more than two increments is more effectively prevented. Ru.

Next, when you release your finger from the push button 14, the pushing member moves downward due to the elastic force of the spring 94, the arm rod 33 rotates counterclockwise, and the striking member 87 moves against the bell 8.
Hit 8 to make a sound.

In this way, when the rotary wheel 5, which was in the position to display "0" on the display section 2, is rotated by one step, the number "1" appears on the display section 2 as shown in FIG. When the push button 14 is pressed down again, the same operation as described above is performed and the number "2" appears on the display section 2.

That is, the same number of numbers as the number of times the push button 14 is pressed is displayed on the display section 2 as the rotating wheel 5 rotates intermittently, and the rotating wheel 7 also rotates intermittently by the same number of times as the rotating wheel 5 rotates intermittently. Let's do it.

The rotary wheels 5 and 7 rotate intermittently while accumulating pressure in return springs 29 and 29, respectively, but at the same time as the push button 14 is released, the bent arms 71 and 73 release the spring 8.
Rotates counterclockwise due to the elastic force of 4..., and the retaining pawl 7
4 and 76 are locked to the pin 26, the rotary wheels 5 and 7 do not rotate back.

As described above, after the push button 14 is depressed to display an appropriate number on the display section 2, the push button 15 is depressed in order to display a number to be added to this number on the display section 3.

That is, when the push button 15 is pressed down, the arm rod 37 and the push-down member 46 perform the same operation as when the push button 14 is pressed down, and the rotary wheel 6 moves intermittently in the same number of times as the number of times the push button 15 is pressed down. It rotates, and the same number as the number of rotations appears on the display section 3.

The rotating wheel 7 also rotates intermittently by the same number of rotations as the rotating wheel 6.

In this case as well, the regulating claws 64 and 65 formed on the feed arms 60 and 61 and the spring 73 fixed to the bent arm 73
Due to the action of the spring 39a provided on the spring 39a and the bulge 39, the rotary wheels 6 and 7 will not rotate more than two steps in one operation.

Therefore, since the rotary wheel 7 rotates intermittently by the same number of rotations as the number of rotations in intermittently increments of each rotary wheel when either of the rotary wheels 5 and 6 is rotated, The result of adding the digits will appear on the display section 4.

Therefore, after pressing down the pushbuttons 14 and 15,
In order to confirm the answer to the addition, the push button 16 is pressed down, the hidden board 8 is pulled down, and the number that becomes the answer is read on the display section 4.

After confirming the answer, the user depresses the push button 17 to rotate the arm rod 40 clockwise about the shaft 22.

Then, the rod-shaped member 42 inserted into the tip of the arm rod 40 rotates upward, and the contact pieces 77, 7 of the bent arms 71, 72, 73
8, 79 from below, lift it up, and bend the bent arm 7.
1, 72, and 73 are rotated clockwise about the shaft 21, and the retaining pawls 74, 75, and 76 and the pin 26.
Release the locked state with...

At the same time as this operation, the rod-shaped member 42 is moved to a rod-shaped member 92. 93 from below and pushes up the member 4
4, 46 are rotated counterclockwise around their respective pivot parts, and the pins 26... and push claws 52, 54,
62, 63 and regulating claws 53, 55, 64, 65
Release the locked state with.

As a result, all the members restraining the return rotation of the rotating wheels 5, 6, 7 are released, and the rotating wheels 5, 6, 7 are released. 7 is rotated back by the accumulated force of the return springs 29...

And each display part 2, 3, 4 is all numbered like the original state.
0” is coming.

It should be noted that the above description is only one embodiment of the present invention, and the number of rotating wheels with addition numbers displayed is arbitrary, and the springs 35a, 39 adjust the rotation of the rotating wheels with moderation.
A, 73 A may be replaced with an elastic member such as rubber.

As is clear from the above description, according to the present invention, a plurality of rotary wheels with addition numbers displayed on the outer circumferential surface and a rotary wheel with answer numbers displayed on the outer circumferential surface are rotatably supported via a return spring, A push-up member is swingably provided with a pushing pawl that engages with a pin provided on the side of each rotating wheel to interlock each rotating wheel displaying an addition number and the rotating wheel displaying an answer number to rotate in intermittently. Furthermore, since a regulating pawl is provided adjacent to the push pawl to prevent the rotary wheel from rotating by two increments, the rotary wheel can be reliably rotated intermittently one increment at a time, making it easy for young children etc. It has many advantages, such as not displaying incorrect answers even if operated roughly.
