Abstract

PURPOSE:To prevent a danger due to the disengagement of a writing instrument by the division of the instrument or the release of locking of a string from fixing fittings when a strong tensile strength is applied to the string engaged with a neck. CONSTITUTION:A writing instrument 1 has a string engaging part 4 in which an engaging string 5 can be inserted at a predetermined position of a barrel. Knots 6 are formed at both ends of the string 5, and locked to fixing fittings 7 to form the string in a looped state. When a specific or more tensile strength is operated at the string 5, at least one knot is removed from the fittings 7, or the fittings 7 are divided, and the looped state can be opened.

Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an improvement in a writing instrument with a string that can be worn around the neck.

[0002]

2. Description of the Related Art Usually, writing instruments such as ball-point pens and mechanical pencils are provided with a clip on the side surface of their barrel.

The string hook portion is not limited to the embodiment, and is provided at a predetermined position of the cap and a similar shaft cylinder.

On the other hand, the fixture 7 is a resin molded product having excellent elasticity, and as shown in FIGS. 3 and 4, the fixture A8 and the fixture B1.
It is composed of two parts. A hole 9 that opens outward and a step 10 are formed inward at one end of the fixture A8, and a locking protrusion 11 is formed at the outer periphery at the other end. Also, the fixture B1
2, a hole 13 and a step 14 are formed at one end, and a locking groove 15 is formed on the peripheral surface of the hole at the other end so as to engage with the locking projection 11 of the fixture A8 and lock. .

Further, both ends of the hanging string 5 are fitted and inserted into the hole 9 of the fixing tool A8 and the hole 13 of the fixing tool B12, respectively, and as shown in FIG. 2, knots 6 and 6'are provided at the ends, respectively. Has been. As described above, the knots 6 and 6'abut on the step portions 10 and 14 of the fixtures A and B, respectively, and are fixed so that they cannot be pulled out, and the locking projections 11 of the fixture A are locked into the locking groove portions of the fixture B. It is elastically locked to 15. The mutual locks can be separated with a predetermined pulling force or more.

5 to 10 show a second embodiment. First, the clip 3'is integrally formed on one side of the cap 2'of the writing instrument 1 '. Further, a string hook 4'through which the hook 5 can be inserted is formed at the rear end base of the clip 3 '. Incidentally, it is basically the same as the first embodiment.

The fixture 20 is a resin molded product and is shown in FIGS. 6 and 7.
As shown in FIG. 5, a hinge 21 is formed on one side in the longitudinal direction, and the hinge 21 is divided into an expanded state. In addition, a semicircular hole 2 that communicates with the outside is provided at both ends of each of the divided parts.
5 and 27 are formed, and step portions 26 and 2 are formed inside the holes, respectively.
8 is formed. Further, a locking groove 23 is formed on one of the divided surfaces, and a locking projection 24 is formed on the other, so that they are elastically locked to each other when combined.

The knots 6 and 6'of the hanging string 5 are placed on the divided one of the fixtures 20, and the knots 6 and 6'abut on the respective step portions to prevent the knots 6 and 6'from coming off. In this state, the other part of the fixture 20 is fitted and the divided portion is locked. Also, the fixture 20
In the vicinity of the holes 25, 27, the slitting parts 29, 30 are appropriately provided.
As shown in FIG. 8, at least one of the hole portions 25 and 27 is expanded when a pulling force of a predetermined amount or more is applied to the hanging cord 5, so that one of the knots 6 and 6'of the hanging cord 5 is formed. Will come out.

[0011]

The writing instrument with a cord of the present invention is configured as described above, and when the cord is strongly pulled while the hanging cord is hung on the neck, the fixing device elastically divides or the knot of the hanging cord from the fixing device. Is removed and the loop state is released.

[0012]

The writing instrument with a cord according to the present invention is as described above, and when the cord is strongly pulled while the cord is hung on the neck, the looped state of the cord is released so that danger is prevented.
