Description

[Detailed description of the invention]

[0001]

[Technical field to which the invention belongs]

 The present invention is to provide a new product that provides users with entertainment by using a knock-down writing instrument such as a mechanical pencil or a ball-point pen to form a knocking section that is used for knocking operation with a removable inverted top member. It is assumed that.

[0002]

[Prior art]

 In writing instruments such as mechanical pencils and ballpoint pens, knocking-out operations of the writing core and writing section are widely performed. In addition, such writing implements are also provided with various decorations to appeal to consumers, rather than merely functioning as writing implements.

In addition, it is also common to add various accessory-like members to such various writing instruments.

[0004]

[Problems to be solved by the invention]

 However, in the above-described conventional technology, even if a toy-like element is added to an accessory-like member, it is usually inseparable from a writing instrument. Even if it is applied to the movement, it is still integrated with the writing instrument.

[0005] In other words, in the above-described writing implement, a member to be removed for refilling the writing core or replacing the writing shaft is used. However, if such a member is removed, the member may be used for a different purpose. No suggestion has been made that it can be used to give the user entertainment.

[0006]

[Means for Solving the Problems]

 The present invention has been made by repeatedly performing experiments and studies on solving the above-mentioned problems in the prior art, and has been developed by forming a removable knock portion as an inverted top member. It is intended to provide new recreational characteristics to the children, and is specifically as follows.

(1) A knock-type writing instrument provided with a knock member at the upper end of a writing shaft for operating the writing section so that the writing section is inserted into and held by the hemispherical top body and the writing shaft. A knock-type writing instrument having a detachable knock portion also serving as an inverted top member, characterized in that the top portion is formed by a cylindrical shaft that also serves as a shaft member for rotating the top body.

[0008] (2) A groove with a lid made of a transparent material is formed on the side of the hemisphere-shaped top of the top of the top of the top of the body, and the size is such that the top of the top of the top of the top can be randomly moved in the groove when the top of the top is rotated. A knock-type writing instrument according to the above (1), wherein a detachable knock portion also serves as an inverted top member.

(3) The groove portion is divided into a plurality of portions by a partition plate so that the sphere stays at any position when the top of the top is stopped. A knock-type writing instrument in which the detachable knock portion described also serves as an inverted top member.

(4) The knock-type writing instrument according to the above (2), wherein the cube is a die, and the removable knock portion also serves as an inverted top member.

[0011]

[Embodiment of the invention]

 The specific embodiment of the present invention will be described below with reference to the accompanying drawings. FIG. 1 is a side view showing an entire writing instrument 1 employing the present invention. The present invention can be applied to both a mechanical pencil and a ballpoint pen as long as it is a knock-type writing instrument 1 in which the upper end of the writing shaft 2 is the knocking portion 3 and the lower end is the writing portion 4. it can. The knock part 3 can be removed in the same manner as used in a general knock type writing instrument, and it is also possible to replace the writing lead and the ink shaft with the knock part 3 removed. The same is true.

The technical characteristic of the present invention is that the knocked portion 3 which has been removed has a shape that forms a top in that state. That is, the knock portion 3 is formed by a hemispherical top body 5 and a cylindrical shaft 6 serving as a shaft when turning the top. Here, the cylindrical shaft 6 is formed in a cylindrical shape so as to be connected to a shaft member holding a writing core or an ink shaft when the knock portion is attached to the writing shaft 2.

Further, since the top body 5 in the present invention has a hemispherical shape as described above, if the top body 5 is turned with a certain strength or more, the hemispherical top body 5 is raised, The shaft 6 serves as a so-called inverted top, which is a lower rotating shaft. This is because the position of the center of gravity when turning the main body 5 is in an inverted state is more stable, and since the top body 5 has a hemispherical shape, it is easy to shift to the inverted state. However, if the knock portion 3 is formed to have substantially the same shape as that shown in the figure, there is no strict condition for making the inverted upside down. Of course, the inverted top which has been rotated is in a stationary state with the top of the hemisphere top 5 and the cylindrical shaft 6 up.

FIG. 2 is a perspective view of the knocking part 3 with the hemispherical main body 5 part down, showing the member configuration. A groove 7 is formed in a flat top surface of the hemispherical top body 5, and the groove 7 is closed by a lid member 8 formed of a transparent material such as plastic. Therefore, the groove 7 is in a state where it can be observed from the outside via the transparent lid member.

A fine motion member 9 shaped like a sphere or a cube is sealed inside the groove 7. The fine motion member 9 is of a size and weight capable of randomly moving around in the space formed by the groove 7 and the cover member 8 when the top body 5 is turned. Therefore, the fine movement member 9 moves around in the groove 7 while the top body 5 is rotating, but because of the size and weight as described above, it almost acts so as to hinder the rotation of the top body 5. do not do. Further, when the top body 5 stops rotating, the fine motion member 9 also comes to rest somewhere in the groove 7.

In the example shown in FIG. 2, a plurality of partitions 10 are further provided in the groove 7, and numbers are assigned to each partitioned location. A spherical body is used as the fine movement member 9. . As described above, when the top 5 is rotated, the sphere in the groove 7 also moves freely, and when the rotation of the top 5 stops, the sphere comes to rest at any of the locations assigned with the respective numbers for each partition. That is, the same relationship as the so-called roulette playground equipment is realized.

If a cube is used as the fine movement member 9 instead of a sphere, and a number from 1 to 6 is applied to each surface of the cube, it becomes the same as a dice, and the rotation of the top 5 is significantly adversely affected. Unless you give two or more cubes, you can enclose one or more dice at random by rotating Top 5 and stopping it. Can be offered.

【The invention's effect】

 According to the present invention as described above, an inverted top which can be used for amusement of a user even when detached from a knocking portion of a knocking type writing instrument which has not been given any particular use as such in the past. It is possible to add functions such as roulette play equipment and dice that can show random eyes as well as knock-type writing instruments, and add new recreational elements to knock-type writing instruments. Since this can be realized with a simple configuration, the present invention is industrially valuable.
