Hereinafter, embodiments of the present invention will be specifically described with reference to the drawings. Note that the following embodiment is one mode for embodying the present invention, and does not limit the present invention within the scope thereof.

FIG. 1 is a sectional view showing a configuration of a mechanical pencil 1 which is a stationery (writing implement) according to an embodiment of the present invention, and FIG. 2 is a sectional view showing a front part of the mechanical pencil 1. In the description of the following embodiments, a central axis extending in the longitudinal direction of the barrel 12 of the mechanical pencil 1 is simply referred to as an axis, and the extending direction is simply referred to as an axial direction. In addition, the tip side on which writing is performed is called the front in the axial direction, and the opposite side is called the back.
The mechanical pencil 1 includes a leading tool 11 having a substantially conical outer shape, a substantially cylindrical barrel 12, a grip 13 as a substantially cylindrical grip, a knock member 18 and a clip arranged at a rear end. 19.
Further, as its internal mechanism, the mechanical pencil 1 has a writing lead tank for storing the writing lead, a chuck unit for gripping and sending out the writing lead, and an elastic member for operating the chuck unit. The internal mechanism of the mechanical pencil 1 can be any known internal mechanism, and a description thereof will be omitted. Further, in other stationery (writing implement) embodiments, the internal mechanism may be an internal mechanism of a ballpoint pen or any other stationery (writing implement). In still other cosmetic embodiments, the internal mechanism may be an internal mechanism of a cosmetic container containing any cosmetic.

The tip 11 is a tapered cylindrical member having a substantially conical outer shape. An opening through which the writing core 2 and the tip pipe 21 holding the writing core 2 penetrate is formed at the tip of the tip tool 11.
A female screw 112 is formed on the inner peripheral surface of the leading tool 11 to be screwed with a male screw 1231 formed on the outer peripheral surface of the front end of the barrel 12 (see FIG. 3). The tool 11 is assembled to the barrel 12.
The leading tool 11 has a protruding portion 111 projecting further rearward from a bottom surface (rear surface) 115 (see FIG. 3) having a substantially conical outer shape. The protruding portion 111 is formed in a cylindrical shape having an outer diameter smaller than the outer diameter of the rear surface 115 of the tool 11, and is inserted into a counterbore 131 formed on the inner peripheral surface at the front end of the grip 13 described later.

The barrel 12 is formed in a substantially cylindrical shape. A grip insertion portion 121 to which a grip 13 described later is assembled is formed at a front portion of the barrel 12. The outer diameter of the grip insertion portion 121 is formed smaller than the outer diameter of the other part of the barrel 12. The grip insertion portion 121 is formed such that the outer diameter at the rear end is substantially the same as the inner diameter of the grip 13 or slightly smaller than the inner diameter of the grip 13. Thus, the rear end of the grip insertion portion 121 is configured such that no gap is generated between the grip 13 and the barrel 12 (grip insertion portion 121).
The outer peripheral surface of the grip insertion portion 121 is formed such that its outer diameter increases toward the rear. In other words, the outer peripheral surface of the grip insertion portion 121 is formed in a tapered shape. With such a configuration, when the grip 13 is assembled to the outer periphery of the grip insertion portion 121 of the barrel, a space that becomes smaller toward the rear between the grip 13 and the grip insertion portion 121 at the front of the grip insertion portion 121. 15 (gap) is formed. This point is the same between the counterbore 131 formed on the inner peripheral surface at the front end of the grip 13 and the grip insertion portion 121, and the space that becomes smaller between the counterbore 131 and the grip insertion portion 121 toward the rear is reduced. It is formed. For this reason, when the O-ring 14 described later is pushed rearward in the space 15, the O-ring 14 can come into strong contact with both the grip 13 and the barrel 12 (grip insertion portion 121) as it goes rearward. it can. An annular protrusion 122 is formed on the front side of the grip insertion portion 121 so as to project radially outward. The outer diameter of the annular projection 122 is formed to be slightly smaller than the inner diameter of the projection 111 of the tool, and when the tool 11 is assembled to the barrel 12, the annular projection 122 is placed inside the projection 111. Can be inserted. By forming the projection 122 on the barrel 12, it is possible to prevent the O-ring 14 and the grip 13 described below from dropping forward of the barrel 12.

グリップ A grip 13 which is a grip portion formed in a cylindrical shape is attached to the outer periphery of the grip insertion portion 121 of the barrel 12. The grip 13 is formed of a material different from the material forming the barrel 12, and is formed separately from the barrel 12. In the present embodiment, the grip 13 is formed of a material that does not substantially elastically deform. With this configuration, even when the shaft cylinder is formed of a material having a relatively low elastic modulus such as a resin, which can be elastically deformed, for example, the shaft cylinder is formed of a metal material having a higher elastic modulus by the tactile feel of the grip. An improved tactile sensation can be obtained, such as an enhanced mechanical pencil. The “material that does not substantially elastically deform” refers to a material having rigidity such that the grip 13 does not elastically deform due to an external force applied to the grip 13 during normal assembly and use of the mechanical pencil 1. Further, the grip 13 is formed of a material having a higher hardness than the material forming the barrel 12. With this configuration, even when the barrel is formed of, for example, a relatively soft material such as resin, the tactile sensation of the grip causes, for example, a mechanical pencil formed of a metal material having higher hardness. An improved tactile sensation can be obtained. Further, the grip 13 is formed of a material having a higher heat transfer coefficient than the material forming the barrel 12. With this configuration, even when the shaft cylinder is formed of a material having a relatively low heat transfer coefficient, such as a resin, for example, the shaft cylinder is formed of a metal material having a higher heat transfer coefficient by the tactile sensation of the grip. An improved tactile sensation, such as a mechanical pencil, can be obtained. In the present embodiment, the grip 13 is formed of a resin material filled with a metal filler. In other embodiments, for example, resin, a shaft cylinder formed of a material having a relatively low specific gravity such as wood, a specific gravity greater than the material constituting the shaft cylinder, for example, metal, glass, ceramic, etc. A grip formed of a material may be assembled. When a grip formed of a material having a higher specific gravity than the material of the barrel is used, the mechanical pencil can be given weight and an improved feeling of weight can be obtained.

環状 An annular counterbore 131 is formed radially inward of the front end of the grip 13 (see FIG. 3). An annular counterbore 131 is formed on the grip 13, and as described later, the O-ring 14 is configured to be pressed rearward by the protrusion 111 of the leading tool 11. The O-ring 14 can be compressed and elastically deformed in the radial direction between the bottom surface (rear end surface) 136 (see FIG. 3) of the annular counterbore 131 of the grip 13 (see FIG. 3). When the O-ring 14 elastically deforms in the radial direction, the O-ring 14 contacts both the barrel 12 and the grip 13 more strongly, and prevents the grip 13 from moving forward with respect to the barrel 12 in the axial direction. The depth (length in the axial direction) of the counterbore 131 is configured to be deeper than the circular diameter d (length in the axial direction of the O-ring 14) of the cross section of the O-ring 14. With this configuration, when the O-ring 14 is assembled to the shaft cylinder 12 as described later, the O-ring 14 can be hidden by covering the outer periphery of the O-ring 14 from the radial outside with the grip 13. . For this reason, it is excellent as a design, and it is possible to prevent the assembled grip 13 from coming off the shaft cylinder 12 due to the handling of the mechanical pencil 1 by the user. The outer peripheral surface of the grip 13 can have any non-slip shape such as groove processing.

A ring-shaped O-ring 14 made of an elastic body and having a circular cross section is disposed between the barrel 12 and the grip 13. The O-ring 14 is disposed in contact with both the barrel 12 and the grip 13 to prevent the grip 13 from moving in the axial direction with respect to the barrel 12. By arranging the O-ring 14, even when the leading tool 11 is detached from the barrel 12, the grip 13 moves forward with respect to the barrel 12, dropping forward, or is orthogonal to the axial direction. It can be prevented from moving in the direction. In addition, by disposing the O-ring 14 so as to be in contact with both the barrel 12 and the grip 13, it is possible to prevent the grip 13 from rotating in the circumferential direction with respect to the barrel 12. Further, when an external force is applied by a user's handwriting in a direction perpendicular to the axial direction in a state where the grip 13 is assembled to the barrel 12, the grip 13 moves in a direction perpendicular to the axial direction with respect to the barrel 12. It is possible to prevent the user from having a feeling of moving. The O-ring 14 is formed of a material having elasticity, and in this embodiment, is formed of an elastomer material. The inner diameter D1 of the O-ring 14 is substantially the same as or slightly smaller than the outer diameter of the distal end portion of the grip insertion portion 121 (near the rear of the projection 122).

With reference to FIGS. 3 and 4, the assembly of the leading tool 11, the barrel 12, the grip 13, and the O-ring 14, and the relationship among the members after assembly will be further described. FIG. 3 is an exploded sectional view showing the front part of the mechanical pencil 1, and FIG. 4 is an enlarged sectional view showing the structure of the front part of the mechanical pencil 1. Illustration of the internal mechanism of the mechanical pencil 1 is omitted.

As shown in FIG. 3, the distal end portion of the barrel 12 (the grip insertion portion 121 and the annular projection 122) is inserted into the center hole of the cylindrical grip 13 and penetrated. The outer diameters of the grip insertion portion 121 and the annular projection 122 are formed smaller than the inner diameter of the center hole of the grip 13. Therefore, it is easy to attach the grip 13 to the barrel 12.
After assembling the grip 13 to the barrel 12, the O-ring 14 is inserted into the space 15 between the barrel 12 and the grip 13 from the front and assembled. First, the O-ring 14 is mounted on the outer peripheral surface of the distal end portion of the grip insertion portion 121 of the barrel 12. After the center hole of the O-ring 14 formed of an elastomer is expanded radially outward to pass rearward through the radially outer side of the projection 122 of the barrel 12 formed in front of the grip insertion portion 121, the O-ring 14 Is restored to the original shape, and attached on the outer peripheral surface of the grip insertion portion 121. In this state, the O-ring 14 is assembled on the outer peripheral surface of the grip insertion portion 121 of the shaft cylinder ahead of the front end surface 135 of the grip 13.

後に After assembling the O-ring 14 on the outer peripheral surface of the grip insertion portion 121 of the barrel 12, the leading tool 11 is screwed into the front end of the barrel 12 and assembled. When the leading tool 11 is screwed into the barrel 12 and assembled, the projection 111 at the rear end of the leading tool 11 is inserted into the space 15 between the grip insertion portion 121 of the barrel and the counterbore 131 of the grip 13. You. As a result, the O-ring 14 assembled to the front end of the grip insertion portion 121 of the barrel 12 is pressed rearward by the protrusion 111, and the O-ring 14 is positioned between the grip insertion portion 121 of the barrel 12 and the counterbore 131 of the grip 13. It is pressed into the space 15. As described above, since the space 15 between the grip insertion portion 121 of the tapered barrel 12 and the grip 13 is formed so as to become narrower toward the rear, the O-ring 14 moves rearward. , O-ring 14 strongly contact both the barrel 12 and the grip 13. Furthermore, the O-ring 14 compressed in the axial direction between the rear end of the protrusion 111 of the leading tool 11 and the bottom surface (rear end surface) of the counterbore 131 of the grip 13 elastically deforms radially inward and outward. As a result, both the shaft cylinder 12 and the grip 13 are more strongly contacted. The O-ring 14 of the present embodiment is formed such that the circular diameter d of the cross section thereof is larger than the protrusion height of the protrusion 122 (the amount of protrusion from the outer peripheral surface of the grip insertion portion 121 to the outside in the radial direction). Further, the inner diameter D3 of the annularly formed protrusion 111 is formed smaller than at least the outer diameter D2 of the O-ring 14. With this configuration, the assembled O-ring 14 suitably contacts both the barrel 12 and the grip 13. The circular diameter d of the cross section of the O-ring 14 is desirably, for example, twice or more the height of the protrusion 122. According to the configuration of the mechanical pencil 1 of the present embodiment, the grip 13 and the O-ring 14 are moved to predetermined positions of the barrel 12 by an easy assembling work in which the leading tool 11 is screwed to the tip of the barrel 12. Easy and accurate mounting. The O-ring 14 comes into contact with the barrel 12 and also comes into contact with the leading tool 11 assembled to the barrel 12, so that the leading tool 11 screwed to the barrel 12 is attached to the barrel 12. In contrast, rotation can be prevented. For this reason, it is possible to prevent the assembled tool 11 and the barrel 12 from loosening and the tool 11 from falling off the barrel 12.

FIG. 4 is an enlarged view showing a configuration of a front portion of the mechanical pencil 1 in a state where the tool 11 is assembled to the barrel 12. FIG. 5 is an enlarged sectional view showing a portion where the O-ring 14 is arranged.
As shown in FIGS. 4 and 5, when the leading tool 11 is assembled to the shaft cylinder 12, the bottom surface (rear face) 115 of the conical outer shape of the leading tool 11 and the front end face 135 of the grip 13 abut. Thereby, the leading tool 11 pushes the grip 13 backward.
When the O-ring 14 is inserted into the space 15 between the barrel 12 (grip insertion portion 121) and the grip 13 (counterbore 131), the O-ring 14 extends radially between the barrel 12 and the grip 13. Compressed. Since the space between the barrel 12 and the grip 13 is configured to be smaller than the circular diameter d of the cross section of the O-ring 14, the O-ring 14 contacts the barrel 12 and the

grip

13 and 13 is locked at a predetermined position in the axial direction of the barrel 12.

When the O-ring 14 is pushed to the deepest portion of the counterbore 131 of the grip by the rear end face 116 of the protrusion 111 of the leading tool 11, the O-ring 14 is moved between the bottom surface 136 of the counterbore 131 and the rear end face 116 of the protrusion 111. Are axially compressed. In this state, the gap between the bottom surface 136 of the counterbore 131 of the grip and the rear end surface 116 of the protrusion 111 of the leading tool is configured to be smaller than the circular diameter d of the cross section of the O-ring 14. For this reason, the O-ring 14 elastically deforms radially outward and inward, and further strongly presses and contacts the inner peripheral surface of the grip (side surface of the counterbore 131) and the outer peripheral surface of the grip insertion portion 121 of the barrel. . For this reason, when an external force is applied in a direction perpendicular to the axial direction by writing by the user, it is possible to prevent the grip 13 from giving the user a feeling of moving in a direction perpendicular to the axial direction with respect to the barrel 12. can do.

As described above, in the present embodiment, the protrusion 122 is further formed in front of the grip insertion portion 121. For this reason, after assembling the grip 13 to the barrel 12 using the O-ring 14, the O-ring 14 is elastically deformed to the outside in the radial direction, and the radially outside of the protrusion 122 is passed through in the forward direction. As long as the O-ring 14 is not removed from the barrel 12, the grip 13 does not accidentally fall forward from the barrel 12. For this reason, even if the front tool 11 is detached from the barrel 12, it is possible to prevent the grip 13 from accidentally dropping forward from the barrel 12.

As described above, according to the mechanical pencil 1 of the present embodiment, the grip 13 can be easily assembled to the barrel 12, and the assembled grip 13 does not easily fall off the barrel 12.
Generally, it is known that a mechanical pencil can be detached from a barrel for maintenance or repair. However, when the grip 13 is made of a material that does not substantially elastically deform and the assembling of the grip 13 to the barrel 12 is easy as in the mechanical pencil 1 of the present embodiment, the grip is It cannot be easily conceived that there is a possibility that it may easily fall off even if it falls off from the vehicle. For this reason, especially when the user is a child, when the tip is removed from the barrel, for example, when the mechanical pencil is shaken vigorously for repair, the grip suddenly flies vigorously. There is a possibility that it will go out. In this case, since the grip formed of a material that does not substantially deform elastically that flew vigorously may damage people and things around it, the grip falls off from the barrel as such It is desired to prevent that. In the configuration of the mechanical pencil 1 of the present embodiment, as described above, the grip 13 falls off from the barrel 12 even when the barrel 12 is strongly shaken in a state where the tip 11 is removed from the barrel 12. This has a special effect that it is possible to preferably prevent such a situation.

In this embodiment, a mechanical pencil has been described as a specific example of a stationery (writing instrument). However, aspects of the present invention are not limited to this, and in other embodiments, any stationery such as a ball-point pen may be used. For example, the same configuration can be applied to any hand tool having a configuration in which a grip is assembled to a cylindrical member. For example, a cosmetic container can be configured as follows.
"A cylindrical body, a grip attached to an outer periphery of the cylindrical body, the grip not being substantially elastically deformed, and an annular concave portion formed at a boundary between the cylindrical body and the grip and opened toward the distal end. And a O-ring that is in contact with both the cylinder and the grip. "
In such an embodiment, the “annular concave portion opening on the distal end side” for arranging the O-ring may be formed at a location that is a boundary between the cylindrical body and the grip. For example, the “annular concave portion opening on the distal end side” may be configured by a concave portion formed on the cylindrical body side, or may be configured by a concave portion formed on both the cylindrical body and the grip. Further, in order to configure the space formed between the shaft cylinder and the grip to be further narrowed toward the rear, a tapered counterbore having a side surface of the counterbore with a slope having a predetermined angle with respect to the axis is used. You may do it.
