Description

[Detailed explanation of the idea] The present invention relates to a writing toy.

Conventional writing toys have characteristics such as shapes, and are designed for the purpose of simply writing; others allow for color changes by replacing the lead; and others have original geometric shapes when used. When drawing patterns, etc., it was necessary to draw them all freehand or with the help of other pattern-forming tools.

The present invention was developed in view of the above circumstances, and consists of a motor with a crayon core, colored pencil core, carbon core, etc. set at the tip of a helical spring with appropriate hardness, and whose rear end protrudes outside the main body of the writing toy. Attached to the shaft via a connecting device, the helical spring is rotated by a motor drive, and the shape of the helical spring is changed by using the pressing force applied to the tip of the lead when writing, allowing you to create geometries with different shapes and sizes. This makes it possible to freely draw continuous patterns, etc. In addition, we have considered that it can be used as a regular writing instrument by regulating the circumference of the lead with a prescribed correction means, so in addition to drawing the above-mentioned geometric continuous patterns, it can also be used as a regular line drawing writing instrument. The idea is to provide a writing toy that is both functional and fun.

An embodiment of the present invention will be described below based on the drawings. FIG. 1 is a perspective view showing the overall structure of the writing toy.

In the figure, 1 is a toy body made of, for example, synthetic resin, 2 is a helical spring with appropriate hardness, 3 is a writing instrument, 4 is an orthodontic cap as a correction means, 5 is a pin clip/switch, and 6 is the above-mentioned toy. Main body 1
It is a removable battery cap that is attached to the rear end of the battery.

Next, a series of mechanisms incorporated inside the toy main body 1 will be explained with reference to FIG.

As shown in the figure, the toy main body 1 is shaped like a hollow, slightly thick pencil case with a small hole at the tip and an open rear end, and a motor 7 and a battery 8 inside.
(In this embodiment, two single batteries are used) can be stored. A shaft 9 of the motor 7 faces a small hole at the tip of the toy body 1, and a helical spring 2 is attached to the shaft 9 via a joint 10 which is a connecting device. Further, a writing instrument 3 is removably attached to the tip of the helical spring 2 via a predetermined chuck.

By the way, as shown in the figure, a correction cap 4 is placed around the helical spring 2, which is a correction means for the helical spring 2, so that even if the helical spring 2 is deformed, the writing instrument 3 will not be displaced. It seems like there is no such thing. The tip of the writing instrument 3 is set so as to be slightly exposed through the hole at the tip of the correction cap 4.

On the other hand, the positive side of the motor 7 is energized by the positive terminal of the battery 8 in direct contact with the anode plate plate 11, and the negative side is energized by the cathode plate 12 and lead terminal 13 in contact with the negative base of the battery 8. , via the switch plate 14 and lead wire 15. By the way, the switch plate 14 is attached to a portion of the inner surface of a ring 16 formed to rotatably attach the pin clip to the outer periphery of the toy main body 1, and when the ring 16 is rotated in the direction of arrows A and B in the figure, The lead terminal 13 and the lead wire 15 are electrically connected at this position.

Hereinafter, the operation, handling, and effects of this writing toy will be explained based on the above embodiment and FIGS. 3 and 4.

First, when the pin clip/switch 5 is rotated in the direction of arrow A or B, the switch plate 14 moves to short-circuit the lead terminal 13 and the lead wire 15. Therefore, a predetermined drive current is supplied to the motor 7, and the motor 7 starts driving. As a result, the helical spring 2 and the writing instrument 3 at its tip rotate, which are connected via the serial device 10 attached to the motor shaft 9, and the helical spring 2 is deformed by the pressing force applied to the tip of the writing instrument 3 during writing. For example, a continuous geometric pattern is drawn as shown in FIG. In addition, by attaching the correction cap 4 of the helical spring 2 to the front part of the toy body 1, the circumference of the writing instrument 3 is regulated and corrected to prevent deformation of the helical spring 2, allowing normal writing as shown in Fig. 4. becomes.

Since the present invention has the above-mentioned structure and function, it is possible to easily draw geometric continuous patterns, which were conventionally difficult for young children, by simply adjusting the pressing force applied to the writing instrument. By attaching a coiled spring correction cap to the toy body, the shape of the coiled spring is prevented from changing, and the area around the flexible tip of the writing instrument is also regulated, so it can fully function as a normal writing instrument. . Further, since the helical spring has the effect of relieving the writing pressure, the pressure is softened and serves to prevent the lead from breaking. For example, if the helical spring correction cap is molded from several different colored semi-transparent resin materials, you can attach a cap that is the same color as the core, allowing you to identify the type of core, or to coordinate with the color of the toy itself. Not only does it protect your fingertips from getting dirty, but it also prevents your fingertips from getting dirty from writing instruments.
Furthermore, if a correction cap having a tip hole that allows the shape of the helical spring to change to some extent is attached to the toy body, the position of the writing instrument will be displaced within the range of play in the hole, making it possible to draw a continuous geometric pattern of a constant shape. In addition, the writing instrument removably attached to the tip of the helical spring can be replaced with crayon lead, colored pencil lead, pencil lead, ballpoint pen lead, magic lead, etc., making full use of the features of conventional writing instruments. It is also fun to be able to write in various tones.

In addition to the above, the mechanism is simple but multi-purpose, such as an electric eraser that replaces the spiral spring with a writing instrument, a portable fan that replaces the coiled spring with blades, and other games that can be played by replacing the attachments. It is a toy with a dream.
