Description

[Detailed description of the invention]

[0001]

[Technical field to which the invention belongs]

 The present invention provides a new product that appeals to the user's entertainment by using moving character members for various writing instruments such as ballpoint pens and mechanical pencils.

[0002]

[Prior art]

 Various writing instruments such as ballpoint pens and mechanical pencils have been widely used in the past, and various efforts have been made to attract consumers' attention by using beautiful decorations and outstanding designs in addition to writing functions.

In recent years, interest in character products has also increased, and it has become common to incorporate this into various writing instruments.

[0004] In addition, a movable part is provided in a part of the character member adopted in this manner, and the character member moves separately from the writing function to satisfy the user's taste and entertainment. ing.

[0005]

[Problems to be solved by the invention]

 However, most of the movements of the above-mentioned character members are apparent at first glance from the physical mechanism thereof, and it is not usually possible to find much unexpectedness in performing various movements.

[0006] In other words, the mechanism of the character member is not obvious at first glance, and various types of movable character members having a type in which the user finds unexpectedness in the operation of the character member itself are unexpected. Writing implements do not exist in the prior art.

[0007]

[Means for Solving the Problems]

 The present invention has been made as a result of repeated studies of improving the points which were not taken into consideration in the above-described conventional technology, and is as follows.

(1) A cylindrical member formed of a transparent material so as to be observable from the outside, a character member substantially inscribed in the cylindrical member and moving up and down inside, and fitted to the upper end of the cylindrical member A writing implement having an automatic elevating mechanism for a character member, comprising: a bellows-type pump member that is held to let air in and out of the cylindrical member; and a writing part that is connected to a lower part of the cylindrical member.

(2) The bellows type pump member located inside the transparent cylindrical member is provided with a whistle member which sounds at the lower end of the bellows type pump member by taking in and out of air. A writing implement with an automatic lifting mechanism for character members.

[0010]

[Embodiment of the invention]

 The specific embodiments of the present invention as described above and shown in the accompanying drawings will be described below.

FIG. 1 is an explanatory drawing showing the operational relationship of an example of a writing instrument 1 according to the present invention. That is, a cylindrical member 3 made of a transparent material such as plastic is attached above the writing portion 2 that performs a writing function, and a bellows type pump member 4 is attached to the upper end side of the cylindrical member 3. A character member 5 that moves up and down in response to the inflow and outflow of air by a bellows-type pump member 4 is enclosed within the box.

In other words, when the bellows-type pump member 4 is pushed in the direction of a white arrow, air is sent into the cylindrical member 3, and the character member 5 is pushed by the pressure of the air, and the inside of the cylindrical member 3 is pushed. It will be sent to the bottom. When the pressing of the bellows type pump member 4 is stopped, the bellows is restored to the initial state. Then, the air inside the cylindrical member 3 is sucked, and the character member 5 is pulled upward. It will be able to be done.

Since the cylindrical member 3 and the writing portion 2 are not in close contact with each other but allow a small gap, a small amount of air sent from the bellows type pump member 4 is small in the gap. When the bellows-type pump member 4 is restored from the pressed state, air is sent into the cylindrical member 3 little by little from this gap.

Here, the inner diameter of the cylindrical member 3 employed in the present invention is about 1 to 1.5 cm, and the shape of the character member 5 is such that it is substantially inscribed inside the cylindrical member 3. Should be selected. In other words, if the character member 5 is large enough to come into close contact with the inside of the cylindrical member 3, the inside character member 5 can move even if air is taken in and out by the bellows type pump member 4. In addition, if the character member 5 is small enough to be able to rotate freely inside the cylindrical member 3, the orientation of the various characters to be used will vary in various ways depending on the inflow and outflow of air. It is because it is lost and the entertainment is lost. Also, the character member 5, which has been pulled up by the restoration of the bellows-type pump member 4, has fallen to the bottom of the cylindrical member 3 due to gravity if the writing implement 1 of the present invention is similarly kept in a substantially vertical state. It goes, but its falling speed is slow because it is almost inscribed as described above.

Also, the weight of the character member 5 needs to be such that it can move up and down inside the cylindrical member 3 when air is introduced and removed by the bellows-type pump member 4. Around 5 grams should be employed.

As long as the size and weight conditions as described above are satisfied, the character member 5 may be of various forms other than those shown in the figures, and may be a character expressing the character in a plane. It can be a three-dimensional representation of a character, one that hangs with a string or the like and vibrates inside, etc. If the length of the cylindrical member 3 is within the allowable range, two or more character members can be used. 5 may be simultaneously enclosed.

As described above, since the cylindrical member 3 of the present invention is formed of a transparent material such as plastic, the operation of each character member 5 as described above can be observed from outside. Further, since such an operation is caused by a change in air pressure, a seemingly obvious physical mechanism is not adopted, and the character member 5 inside the cylindrical member 3 has no characteristic. It appears to be floating up and down without the application of external force, and seems to be moving up and down automatically, which is surprising to consumers, etc., and is more entertaining and hobby Is high.

In order for the character member 5 to smoothly move up and down inside the cylindrical member 3, air should be appropriately discharged from the end of the cylindrical member 3, and a vent hole for this purpose should be provided. The part 6 is formed on the upper end side of the cylindrical member 3.

Further, if a whistle member 7 is attached to the tip of the bellows-type pump member 4 located inside the cylindrical member 3 as shown in FIG. A sound is emitted from the whistle member 7, and in this regard, it is also possible to provide the consumer with new entertainment.

[Effect of the invention]

 According to the present invention described above, a character member that moves up and down in response to a change in air pressure is inserted into a cylindrical member made of a transparent material to realize unexpected character operation. Therefore, it is a highly industrial valued product because it satisfies the hobbies and recreational needs of consumers.
