Abstract

(57) [Summary] [Problem] A writing instrument owner can easily provide the name or address of the owner or characters such as dreams and wishes on the grip portion of the writing instrument, and arbitrarily display or hide the characters. Be able to display. SOLUTION: In the conventional writing instrument, it is very difficult to remove the elastic pipe and provide a character on the grip section because the elastic pipe of the grip section strongly tightens the writing instrument shaft section. In order to improve this point, a solid pipe 22 is provided below the elastic pipe 23, and the solid pipe is designed to hold the tightening force of the elastic pipe. Thereby, since the solid pipe and the elastic pipe can be easily removed, it is possible to easily provide a character on the grip portion. In addition, since the grip can be rotated by introducing the solid pipe, the transparent portion and the opaque portion are provided on the elastic pipe or the solid pipe to display or hide characters provided on the grip. Can be arbitrarily selected.

Description

[Detailed description of the invention]

[0001]

[Technical field to which the invention belongs]

 The present invention relates to an improvement in a grip portion of a writing instrument so that a purchaser of the writing instrument can set an arbitrary character inside a grip portion of the writing instrument and can select whether to display or hide this character. It is.

[0002]

[Prior art]

 To be able to provide characters on the grip of the writing implement has the same effect as described in `` Effects of the Invention '', but the purchaser writes characters on the grip of the conventional writing implement. At present, there is no such place. However, Japanese Patent Application Laid-Open No. 7-276887 has proposed a method of providing characters on the grip portion. In this patent, it is proposed that a letter for a company name or the like be provided on a handle shaft portion of a writing instrument, and a transparent elastic pipe be placed over the letter to protect the letter.

In the present invention, a purchaser of a writing instrument provides arbitrary characters on the writing instrument and arbitrarily selects display or non-display thereof, which is different from the above-mentioned Japanese Patent Application Laid-Open No. 7-276887. Have a purpose. Therefore, if the method presented in the above-mentioned Japanese Patent Application Laid-Open No. 7-276887 is applied to this purpose, there are the following inadequate points.

First, in Japanese Unexamined Patent Application Publication No. 7-276887, since an elastic pipe is inserted directly over a character, the elastic pipe strongly tightens a shaft portion of a writing instrument. It is extremely difficult to remove the elastic pipe to provide the text, and it is similarly more difficult to replace it with the text sheet.

[0005] Second, when writing characters such as the owner's dreams, wishes, goals, etc., it is often thought that it is often desirable to keep it secret from others because it includes personal content. In the case of Kaihei 7-276887, since the purpose is to protect letters for advertisement from wear, etc., there is no idea of concealment and concealment is impossible at all.

Third, since there is no idea of secrecy as described above, there is no idea of switching between display and non-display. That is, the writing implement owner cannot arbitrarily display or hide the characters.

As described above, in the conventional technology, it is not considered that the owner of the writing instrument provides an arbitrary character on the grip portion and arbitrarily switches between display and non-display thereof, and a method therefor. Not even.

[0008]

[Problems to be solved by the invention]

 The elastic pipe used for the grip part of the current writing instrument strongly tightens the shaft of the writing instrument. In order to make it easy for the purchaser to remove this, it is necessary to loosen the tightening. However, when the tightening of the elastic pipe is weakened, a feeling of floating occurs when the writing instrument is squeezed. Therefore, it is an issue to be solved that it can be removed without giving a floating feeling.

Further, in order to display or hide characters, a transparent portion and an opaque portion are partially provided on an outer pipe of a sheet on which the characters are written, and the display or non-display is performed by rotating the portions. It is conceivable to select the display. However, if the elastic pipe in the case of JP-A-7-276887 is made rotatable, a feeling of lifting occurs when the writing instrument is gripped and tightened as described above.

[0010]

[Means for Solving the Problems]

 In order to solve the above problems, a solid pipe is provided inside the elastic pipe, and the tightening force of the elastic pipe is held by the solid pipe. As a result, the solid pipe and the elastic pipe at the grip can be removed from the writing tool shaft without causing a floating feeling. Since the elastic pipe and the solid pipe are removed by removing the tip of the writing implement (Lopra) that has been screwed, the removal operation becomes extremely easy, and the owner can set the character on the handle shaft of the writing implement. You can easily do it.

In addition, if an appropriate gap is provided between the grip portion shaft and the solid pipe, the grip portion can be rotated. Therefore, a transparent portion and an opaque portion are provided on either the solid pipe or the elastic pipe. For example, by rotating them, it is possible to arbitrarily select display or non-display of characters written on the sheet.

On the other hand, when a character provided in the grip portion is viewed through an elastic pipe, it is difficult to see the character clearly. This is because the elastic resin used for the elastic pipe often has insufficient transparency. Further, in the case of an elastic resin, there is a case where dirt is easily attached and it is difficult to maintain the initial transparency. Furthermore, when the solid pipe and the elastic pipe are overlapped, the letter below may be difficult to see due to extra refraction of light at the boundary of the resin. As a method of improving this point, it is conceivable to provide a convex portion on the solid pipe and make a hole in a wall portion of the elastic pipe corresponding to the convex portion of the solid pipe.

As a problem when a hole is provided in the elastic pipe, it is conceivable that a crack may be formed in the elastic pipe from the hole with use. For this reason, it is conceivable to stop installing the hole of the elastic pipe and to make the wall thickness of the elastic pipe corresponding to the hole thinner.

As a method of providing a grip portion on a writing instrument such as a pencil without a fixed grip portion, a pipe has an inner cross-sectional shape that is the same as the outer cross-section of a shaft portion of the writing instrument, and an outer cross-sectional shape of a pipe that is circular. It is conceivable to use a modified cross-section pipe and use it as the grip shaft. By inserting a solid pipe or an elastic pipe as described above on this irregular cross-section pipe, a grip portion for providing an arbitrary character can be formed. At each end of the pipe with irregular cross-section, parts for fixing the solid pipe, such as a convex part, a screw part and a nut part, are required.

When the character provided on the grip portion is provided with an opaque portion for hiding the character, incident light is reduced and the character becomes difficult to see. As a solution to this problem, it is appropriate to use fluorescent ink, luminous ink, gold ink, and silver ink when writing characters on the sheet below the solid pipe.

[0016]

[Embodiment of the invention]

 An embodiment of the invention will be described with reference to the drawings. In each of the working drawings, the number of transparent parts and the like is limited, but this is for the sake of simplicity, and does not mean a limitation on the working.

(Example 1) Claim 1 proposes that a solid pipe is inserted under an elastic pipe, and the tightening force of the elastic pipe is held by the solid pipe. One example of the implementation in this case is shown in FIG. The handle shaft portion 20 of the writing instrument is made slightly thinner than the other shaft portions 30, and a sheet 21 for writing characters is affixed on the shaft portion. On top of this, a solid pipe 22 having a rectangular transparent portion 22a and other opaque portions 22b is filled. The thickness of the solid pipe 22 should be such that there is a slight gap between the gripper shaft 20 and the sheet 21 so that the solid pipe 22 can be rotated while being fitted on the gripper shaft 20 or the sheet 21. . Furthermore, a transparent elastic pipe 23 is entirely covered on the outside of the solid pipe 22 to form a grip for a writing instrument. Instead of the sheet 21, the surface of the shaft portion 20 can be used as a place for printing characters by making the surface state in which characters can be written or printed.

(Second Embodiment) A second embodiment of the present invention provides a method for solving the incomplete transparency of the elastic pipe 23. As shown in FIG. 2, a part of the transparent solid pipe 24 is defined as a convex part 24a, while a part corresponding to the convex part 24a of the elastic pipe 25 is defined as a hole part 25a. As a result, the characters can be seen clearly only through the solid pipe having good transparency.

The surface of the elastic pipe 25 is substantially the same as or slightly higher than the surface of the convex portion 24a of the solid pipe. If the elastic pipe surface is slightly raised, the finger will not hit the solid pipe 24 when it is squeezed, preventing a decrease in gripping comfort. In addition, the solid pipe's convex portion 24a is scratched by touching objects and scratching. It is also possible to prevent the property from being reduced.

On the other hand, if an opaque resin is used for the elastic pipe 25, the characters printed on the sheet 21 can be seen only through the highly transparent convex portion 24a, so that these can be seen clearly. By rotating the solid pipe 24 and the elastic pipe 25, the display or non-display of the character can be arbitrarily selected. As the elastic pipe 25, a dark color transparent elastic resin other than the opaque resin can be used.

(Third Embodiment) As a problem of the second embodiment, there is a possibility that the elastic pipe 25 provided on the solid pipe 24 may be cracked from the hole 25a to cause peeling. Although the problem of cracking and peeling can be solved by bonding the elastic pipe 25 to the solid pipe 24 using an adhesive, there is a disadvantage that one step is added. Therefore, the following compromise may be considered to solve the problems of peeling and improvement of transparency. As shown in FIG. 3, a part of the solid pipe 26 is formed as a convex part 26a, and the wall thickness of a part 27a corresponding to the convex part 26a of the elastic pipe 27 is reduced. As a result, the solid pipe layer having good transparency is thick, and the layer of the elastic pipe having low transparency becomes a thin grip portion, so that the characters inside can be seen clearly.

Example 4 In the case of a writing instrument having no fixed grip, as shown in FIG. 4, the cross section of the pipe has the same shape as the cross section of the writing instrument shaft, and the outer cross section of the pipe has a circular shape. Is inserted into a writing instrument to form a grip shaft. In order to fix the solid pipes (22, 24, 26) and the elastic pipes (23, 25, 27) to the deformed cross-section pipe 28, a convex portion 28a is provided at one end, and a convex portion 28a is provided at the other end. A nut portion 28c to be combined with the male screw portion 28b is provided. The solid pipes (22, 24, 26) and the elastic pipes (23, 25, 27) are combined and fitted to the outside of the modified cross-section pipe 28. The solid pipe and the elastic pipe are fixed on the odd-shaped cross-section pipe by tightening the nut 28c with a screw, thereby forming a grip for the writing instrument. As described above, it is possible to arbitrarily display or hide arbitrary characters by providing a grip on a writing instrument having no grip. Provide a small gap between the writing tool shaft and the irregularly shaped pipe so that it can slide as the writing tool wears out.

Fifth Embodiment As shown in FIG. 5, unevenness 29 a is provided at one end of the grip shaft 20, and similar unevenness 29 b is provided on the inner surfaces of the corresponding solid pipes 22, 24, 26. As a result, the rotation of the grip portion is made stepwise, and the display or non-display state of the character due to the careless rotation does not occur. If the same thing as the unevenness 29a is also provided on the tip part (ropler) 10 and the same thing as the unevenness 29b is provided on the inner surface of the other end of the solid pipes 22, 24, 26, more stable rotation can be obtained. . Also, by adjusting the height of the irregularities 29a and 29b, the gap between the shaft 20 and the solid pipes 22, 24, 26 can be adjusted. Wear of the surface can be prevented. Similarly, the grip portion using the deformed pipe 28 can be provided with irregularities to stabilize rotation.

(Embodiment 6) If a small projection is provided on the inner surface of the irregularly shaped pipe 28, when the irregularly shaped pipe is inserted into the writing instrument, the projection slightly bites into the shaft of the writing instrument. This becomes resistance when sliding on the writing instrument shaft, so that the entire grip portion can be prevented from falling off the writing instrument. Further, since the gap between the writing implement and the irregularly shaped pipe can be made slightly larger by this projection, it is possible to prevent a situation in which the irregularly shaped cross section pipe 28 does not fit into the writing implement.

Example 7 By writing characters to be written or printed on the sheet 21 with a fluorescent ink, a luminous ink, a gold ink, a silver ink, or the like, the visibility is enhanced and the decorativeness is enhanced. Can be done.

[0026]

[Effect of the invention]

 The present invention devises a method for providing an arbitrary character on the grip portion of a writing instrument. First, the effect of providing a character on the grip portion of the writing instrument will be described.

For example, by attaching letters such as a name, a nickname, and an address to a writing implement owned by a schoolchild or the like, it is possible to reduce the loss or mistaken holding of the writing implement at a school or the like.

Further, if the dream or wish of the owner is provided in the grip of the writing instrument, the grip has the meaning of “gripping” as its name implies, so “gripping” the dream or hope, that is, the dream And hope can be achieved. Each squeeze of the writing implement can give the joy of approaching the achievement of a dream or hope.

In the writing instrument with an improved grip portion according to the first aspect, since the elastic pipe is held by the solid pipe, the solid pipe and the elastic body are removed by removing the writing tool tip part (Lopra). Both pipes can be easily removed from the writing instrument body. If the owner of the writing implement sets an arbitrary character on the grip part shaft, refills the solid pipe and the elastic pipe, and fixes the tip parts, the writing implement is restored, and by rotating the elastic pipe, The display or non-display of an arbitrary character can be arbitrarily selected.

[0029] In the writing instrument with the improved grip portion described in claim 2, the character can be seen through only the convex portion of the highly transparent solid pipe, so that the character can be easily seen. Also in this method, it is needless to say that the owner of the above-mentioned writing instrument can easily provide characters and can select display or non-display of characters.

[0030] In the writing instrument with the improved grip portion described in claim 3, the elastic pipe having insufficient transparency is made as thin as possible to prevent the characters from being blurred, and to reduce the elastic pipe. By integrating them, problems such as cracks and separation from solid pipes are eliminated.

The grip section can be formed by using the modified cross-section pipe described in claim 4 as a grip section, and inserting a solid pipe and an elastic pipe outside the pipe. As a result, even in a writing instrument such as a pencil having no fixed grip portion, the owner of the writing instrument can provide an arbitrary character on the grip portion and can arbitrarily select display or non-display of this character. Since the proper gripping position moves as the pencil is sharpened, the gripping position using a pipe with a modified cross-section can be adjusted by sliding it on the pencil axis.

By using the ink described in claim 5, the characters provided on the grip portion are easy to see and the decorativeness is good.
