[Detailed description of the invention]

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a diagram drawing toy capable of drawing a diagram of a plurality of symbols.

[0002]

2. Description of the Related Art Conventionally, there has been known a drawing toy in which a writing implement attached to the tip of a hollow case-like gripper vibrates (Japanese Utility Model Laid-Open No. 52-131142 and Japanese Utility Model Laid-Open No. 53-63943). Gazette). When trying to draw a line with these line drawing toys, the writing instrument is always vibrating, so a fine loop becomes a continuous line.

[0003]

[Problem to be Solved by the Invention] However, the above-mentioned drawing toy merely draws a continuous line of fine loops, and cannot draw a diagram of a special pattern automatically. Was.

According to the present invention, two or more kinds of patterns can be automatically drawn by a switching operation, and can be manually moved arbitrarily as in the case of using a normal pen with a hand.
An object of the present invention is to provide a line drawing toy capable of changing the design in various ways.

[0005]

According to the present invention, there is provided a diagrammatic drawing toy having a rotating plate having a brush tip provided on a front surface and a rotating shaft having a gear on a back surface, and a rotating shaft of the rotating plate being eccentric. Rotating plate supporting means rotatably mounted, a rotation drive mechanism for rotating the rotating plate supporting means, and a gear portion meshing with a gear of a rotating shaft of the rotating plate, and engaging with the rotating plate supporting means A switching member movable between a position to be engaged and a position not to be engaged, wherein the switching member is configured to rotate integrally with the rotating plate supporting means when engaged with the rotating plate supporting means. It is characterized by having done.

[0006] By using the drawing toy of the present invention having such a configuration, it is possible to automatically draw a plurality of special design lines by moving the switching member.

If the gear portion of the switching member has a plurality of gears having different numbers of teeth, three or more types of symbols can be automatically drawn by moving the switching member.

Further, even when the gear of the rotation axis of the rotation plate is constituted by a plurality of gears having different numbers of teeth, three or more kinds of symbols can be automatically drawn by moving the switching member.

[0009]

According to the present invention, when the rotating plate supporting means having the eccentrically mounted rotating plate provided with the writing implement rotates, the writing implement follows a circular orbit. Since the gear portion of the switching member meshes with the gear that is axially attached to the rotation axis of the rotation plate, when the switching member rotates integrally with the rotation plate supporting means, the rotation plate does not rotate,
A circular orbit is maintained.

When the switching member is moved to a position where it does not engage with the rotating plate supporting means, the switching member does not rotate. At this time, the gear pivotally mounted on the rotating plate meshes with the gear portion of the switching member, but since this gear portion is not rotating, when the rotating plate supporting member rotates, it meshes with the stopped gear portion. The gear of the rotating shaft inevitably rotates in order to move with the rotation of the rotating plate supporting member. As a result, the rotating plate rotates while revolving with the rotating rotating plate support member. The trajectory of the writing instrument becomes an ellipse or another geometrical figure by combining the revolution of the rotating plate and the rotation.

When the switching member is not rotating, a figure defined by the ratio of the number of teeth of the gear of the rotating shaft of the rotating plate to the number of teeth of the gear portion of the switching member is drawn as the trajectory of the writing implement. Therefore, by changing the ratio of the number of teeth,
Many kinds of designs can be drawn automatically.

The cylindrical member 63, the locking member 81, the cylindrical member 42, and the motor 35 are housed in the holding portion 15, and the operating portion of the switch 13 projects outside through the hole 14 of the upper casing 15a. A cover 25 is provided at the tip of the gripper 15.
Is inserted so that only the tips of the brush tips 19a and 19b protrude outside.

Next, the operation of the diagrammatic toy 10 will be described with reference to FIGS.

In FIG. 3, the changeover switch 13 is set to the position A at the most distal end. When the power switch 11 is turned on, the pinion 36 is rotated by the motor 35, and this rotation is transmitted to the gear 43 via the reduction gears 37, 39, 41.

Since the gear 43 is mounted on the revolving shaft 48, the circular members 23 and 47 rotate together with the gear 43 (hereinafter referred to as revolving). Accordingly, the rotating plate 21 eccentrically attached to the circular member 23 revolves in a circle.

At this time, the switching member 69 is configured such that the protrusion 75 protruding inward is formed by the protrusion 4 protruding rearward of the circular member 47.
6 and revolves integrally with the circular member 47. As a result, the gear 55 of the rotation shaft 51 that moves on the revolving circular member 47 simply moves while meshing with the inner peripheral gear 65 of the revolving switching member 69, and the rotation shaft 51 itself rotates (hereinafter, referred to as rotation). )do not do. At this time, the trajectory of the writing tip is a circle as shown in FIG.

Next, as shown in FIG.
3 is moved to the center position B, the protrusion 7 of the changeover switch is moved.
Since 3 is fitted in the groove 71 provided on the outer periphery of the switching member, the switching member 69 also moves to the center position.

When the power switch 11 is turned on, the pinion 36 is rotated by the motor 35, and this rotation is transmitted to the gear 43 via the reduction gears 37, 39, 41.

Since the gear 43 is mounted on the revolving shaft 48, the circular members 23 and 47 revolve integrally with the gear 43. Accordingly, the rotating plate 21 eccentrically attached to the circular member 23 revolves in a circle.

The above description is based on the changeover switch 13 shown in FIG.
Is set to the position A at the most distal end.

However, the projection 75 projecting inside the switching member 69 is separated from the projection 46 projecting rearward of the circular member 47, and the projection 72 projecting rearward of the switching member 69.
Engages with the locking projection 83 inside the locking member 81, and the switching member 69 is stopped.

The gear 5 attached to the rotation shaft 51 of the rotation plate 21
5 meshes with the inner peripheral gear 65 of the switching member 69, but since the inner peripheral gear 65 does not revolve, the circular member 23
And 47 revolve, the gear 55 meshing with the stopped inner circumferential gear 65 necessarily moves with the circular members 23 and 47, and thus inevitably rotates. As a result, the rotating plate 21
Is revolving while revolving with the revolving plate members 23 and 47.

The number of teeth of the gear 55 is 24, and the number of teeth of the first inner peripheral gear 65 is 48. The greatest common divisor of the number of teeth of the gear 55 and the inner gear 65 is 24, and the number of teeth of the inner gear 65 is 24.
The value divided by is 2. As a result, the trajectory of the writing tip of the writing member 17 has an elliptical shape as shown in FIG.

Next, as shown in FIG.
When 3 is moved to the rearmost position C, the switching member 69 also moves to the rearmost position because the projection 73 of the changeover switch is fitted in the groove 71 provided on the outer periphery of the switching member 69.
At this time, the gear 55 of the rotation shaft 51 of the rotation plate 21 meshes with the second inner peripheral gear 67 of the switching member 69.

When the power switch 11 is turned on, the pinion 36 is rotated by the motor 35, and this rotation is transmitted to the gear 43 via the reduction gears 37, 39, 41.

Since the gear 43 is mounted on the revolving shaft 48, the circular members 23 and 47 revolve integrally with the gear 43. Accordingly, the rotating plate 21 eccentrically attached to the circular member 23 revolves in a circle. The projection 75 projecting inside the switching member 69 is separated from the projection 46 projecting rearward of the circular member 47, and the projection 72 projecting rearward of the switching member 69 is engaged with the locking projection 83 inside the locking member 81. In this case, the switching member 69 has stopped. The above is the same as the case where the changeover switch 13 shown in FIG.

That is, the gear 55 attached to the rotation shaft 51 of the rotation plate 21 meshes with the inner peripheral gear 67 of the switching member 69, but since the inner peripheral gear 67 does not revolve, the circular members 23 and 47 When revolving, the gear 55 meshing with the stopped inner peripheral gear 67 becomes circular members 23 and 47.
It is inevitably rotating because it needs to move with it. As a result, the rotating plate 21 rotates while revolving with the rotating plate members 23 and 47 that revolve.

However, the gear 55 attached to the rotation shaft 51 of the rotation plate 21 is connected to the second inner peripheral gear 6 of the switching member 69.
7 is engaged. The gear 55 has 24 teeth, and the second inner peripheral gear 67 has 50 teeth. The greatest common divisor of the number of teeth of the gear 55 and the inner peripheral gear 67 is 2, and the value obtained by dividing the number of teeth of the inner peripheral gear 67 by 2 is 25. As a result, the trajectory of the brush tip becomes a floral pattern having 25 petals shown in FIG. 6 (C).

Although the embodiments have been described above, the present invention is not limited to the above-described embodiments, and various design changes and addition of new configurations are also included in the scope of the present invention.
For example, the number of brush tips may be one, or three or more. The number of gears attached to the rotation shaft of the rotation plate may be two or more, and the number of gears of the switching member may be one or two or more.

[0041]

As described above, according to the present invention, the combination of the rotation and stop of the rotating plate on which the brush tip is attached and the revolution of the support means eccentrically mounted on the rotating plate is achieved by moving the switching member. By selecting this, multiple types of figures are automatically drawn, and by adding the movement of the hand to the movement of the brush tip, the player can draw a diagram that exceeds the player's expectation There is.
