Description

DETAILED DESCRIPTION OF THE INVENTION [Industrial Application Field] The present invention relates to a writing instrument used outdoors.

[Prior art and its problems]

Writing instruments are often equipped with clips for convenient portability. Then, a writing instrument is mounted in a pocket or the like and carried, but for example, when performing sports or recreation in the open air, a participant or a referee of sports or recreation may record or score while moving. At this time, it is troublesome to take out the writing instrument from the pocket each time recording or scoring, and it is easy to drop the writing instrument because there is a problem that if the writing instrument is always held in the hand, it interferes with the activity.

Therefore, if you attach a string for hanging on the tail end of the barrel and hang the string on the neck and hang the writing instrument on the chest, immediately pick up the writing instrument in your hand when recording or scoring. You can do it, and when you are finished writing, just remove the writing instrument from your hand, and the writing instrument will drop and be hung on your chest.
It is suitable for recording and scoring outdoor sports and recreation, as it does not need to be taken in or out of your pocket and does not interfere with your activities.

However, in order to attach the cord, for example, the attachment hole is passed through the shaft cylinder and the cord is passed through this hole, or a dedicated part is attached to the tail end of the shaft cylinder, and the cord is attached to this part. There are problems that the number of manufacturing processes increases, the labor is required for mounting, and the number of parts increases.

[Purpose of device]

Then, this invention aims at providing the writing instrument which can attach a string easily, without increasing the number of parts.

[Constitution of the device and its action]

In the writing instrument of the present invention, a groove is formed in the pedestal of the shaft cylinder to which the clip is fixed, a string for neck hanging is fitted in the groove, and the clip attachment portion fitted into the holding cylinder protruding from the pedestal is attached. It is characterized by covering and attaching this string.

That is, since a groove is formed in the pedestal of the shaft cylinder to which the clip is fixed and the string fitted in this groove is covered by the clip attaching portion to be attached, that is, the string is attached using the clip attaching structure, A dedicated part for attaching the string is not necessary and can be attached securely.

〔Example〕

The present invention will be described in detail below with reference to the embodiments shown in the drawings.

In FIG. 2, a circular pedestal 14 is formed on the peripheral surface in the vicinity of the tail end of a thick shaft cylinder 1 formed of synthetic resin.
A cylindrical holding cylinder 11 is projectingly provided on the top of the cylinder 14. An annular locking protrusion 12 is formed on the inner peripheral surface of the holding cylinder 11, and four cut grooves 13 are formed on the upper edge of the holding cylinder 11. A substantially U-shaped groove 15 is formed at the tail end side of the pedestal 14.

Similarly, on the base end side of the clip 2 made of synthetic resin,
As shown in FIGS. 3 and 4, a cylindrical mounting portion 21 whose outer diameter is equal to that of the pedestal 14 of the shaft cylinder 1 is integrally connected. An inward flange 24 is formed in the mounting portion 21, four ribs 23 are formed below the inward flange 24, and four claws 22 are formed further inward from the inward flange 24. Has been done. here,
The virtual inscribed circle of the four ribs 23 is equal to the outer diameter of the holding cylinder 11,
The size of the claw 22 is also equal to that of the cut groove 13.

As shown in FIG. 5, the fixed tube 3 has a cylindrical shape with a bottom, a circular locking groove 32 is formed on the peripheral surface whose outer diameter is equal to the inner diameter of the holding tube 11, and a flange is provided at the upper end. The part 31 is formed.

Then, at the time of assembly, first, as shown in FIG. 6, the string 10 is fitted into the groove 15. The string 10 is for hanging a writing instrument around the neck, and is a cloth-made twisted string having an outer diameter of 2 mm and a length of about 70 cm. And the mounting portion 21 of the clip 2
When is fitted on the outside of the holding cylinder 11 of the shaft cylinder 1, the ribs 23 come into contact with the outer peripheral surface of the holding cylinder 11, and the claws 22 are cut into the cut grooves 13.
It becomes impossible to rotate by being fitted in. Then, the fixed tube 3 is fitted into the holding cylinder 11, whereby the locking projection 12 and the locking groove 32 are engaged with each other, and the flange portion 31 presses the inward flange 24 and the claw 22 of the mounting portion 11. . Therefore, the mounting portion 21 of the clip 2 has the groove 15
And a strap 10 is attached as shown in FIG.

In this way, since the string 10 is attached to the tail end of the barrel 1, when the string 10 is hung on the neck, the writing instrument is hung on the chest. Therefore, you don't need to take it out of the pocket, you can immediately pick up the writing implement in your hand and write it. It is a writing instrument that is suitable for recording and scoring outdoor sports and recreation without disturbing you. Then, the string 10 is fitted into the groove 15 formed in the pedestal 14 of the shaft cylinder 1 so as to be attached by being covered with the attachment portion 21 of the clip 2, that is, the string 10 is attached using the attachment structure of the clip. There is an advantage that a dedicated component for attaching the string 10 is not necessary and the attachment can be surely performed.

[Effect of device]

As explained above, since the string for hanging on the neck is attached using the attachment structure of the clip, the number of parts does not increase and it is possible to easily attach the string, recording sports such as outdoor sports and recreation and It can be a writing instrument suitable for scoring.
