Description

[Detailed Description of the Invention] (Industrial Application Field) The present invention relates to a clip attachment device for attaching a clip used for a writing instrument to a cylindrical body such as a barrel or a cap barrel of the writing instrument.

(Prior art and its problems) Conventional writing instrument clip attachment devices include those that prohibit insertion of the base of the clip into the window hole provided in the cylinder, and those that prevent the base of the clip from being inserted into the opening at one end of the cylinder. There are known clips in which the base of the clip is held between the inner wall of the cylindrical body and the locking member by fitting the locking member into the opening.

However, in either case, since the clip base is located protruding inside the cylinder, there are mechanical parts (for example, the lead feed mechanism of a sharp pencil or the refill of a ballpoint pen) inside the cylinder. forward/backward mechanism, inner cap to prevent drying, etc.)
However, there remained the problem that it became an obstacle in the deployment of

(Purpose of the invention) The present invention was devised in view of the above-mentioned conventional problems, and aims to provide a clip attachment device that can prevent the protrusion of the base and other parts of the clip into the cylindrical body as much as possible. be.

(Structure of the invention) Hereinafter, the invention will be described in detail based on embodiments shown in the accompanying drawings.

In FIG. 1, reference numeral 1 indicates a cylindrical body such as a barrel or a cap tube of a writing instrument, and a part of the side wall of the cylindrical body 1 may be bent outward at any location on the side wall of the cylindrical body 1. A locking piece 2 is formed in an upright manner, and a locking portion indicated by reference numeral 3 is formed on the free end side of the locking piece 2 by further bending the locking piece 2 downward. be. Reference numeral 4 is a hole provided above the locking piece 2 in the side wall of the cylinder 1, and the hole 4 has a protrusion 6a (a protrusion 6a) formed on the first contact portion 6 of the clip 5, which will be described later. (see Figure 3) is inserted and locked. The member indicated by reference numeral 5 is a clip, and the clip 5 has a hole 7 into which the locking piece 2 can be inserted, and a first hole 7 formed by bending the clip 5 at the upper end. The abutment part 6 of, and the lower end part,
Similarly, second contact portions 8 are formed by bending. The member indicated by reference numeral 9 is a locking member, and the locking member 9 includes a flange 10 that is larger than the hole 7 of the clip 5, and a hole 7 in which the locking piece 2 is inserted into the hole 7. A fitting portion 11 is formed to have a shape that can be fitted into the fitting portion 11. Further, the fitting portion 11 is provided with a protrusion indicated by reference numeral 12, and due to the presence of the protrusion 12, the cylindrical body 1 of the fitting portion 11 is
It is designed to prevent you from immersing yourself inside.

Next, the installation procedure of the embodiment shown in FIGS. 1 to 3 will be explained.

Insert the locking piece 2 into the hole 7 of the clip 5, bring the first and second contact parts 6, 8 of the clip 5 into contact with the outer surface of the cylinder 1, and in this state, insert the clip 5 into the cylinder 1. On the other hand, until the protrusion 6a of the first abutment part 6 is inserted into the hole 4, the approximately middle part of the clip 5 is pressed and curved toward the cylindrical body 1 and slid upward. At the same time as the protrusion 6a of the first abutment part 6 is engaged with the hole 4, the engagement part 3 of the engagement piece 2 is engaged with the lower end of the hole 7. If the pressure on the clip 5 is released here, the clip 5 will try to return to its original state due to its own elasticity, but since the locking part 3 is engaged with the lower end of the hole 7, it will not return to its original state. The return is blocked midway through, and the first and second abutting portions 6, 6 of the clip 5,
8 is pressed against the outer surface of the cylindrical body 1 by the own elasticity of the clip 5. Next, the fitting portion 1 of the locking member 9 is inserted into the hole 7 in which the locking piece 2 is inserted.
1 from the outside to prevent the locking piece 2 and the hole 7 from shifting (see FIG. 2).

In FIG. 4, reference numeral 101 indicates a cylinder;
The cylindrical body 101 is placed at an arbitrary location on the side wall of the cylindrical body 101.
An upright locking piece 102 is formed by bending a part of the side wall of the locking piece 102 outward.
A locking portion 103 is formed by bending the free end side. Reference numeral 104 is a hole formed by raising the locking piece 102. A member designated by reference numeral 105 is a clip, which has a hole 107 and first and second abutting portions 106 and 108 at the upper and lower ends, as in the previous embodiment. Further, a member indicated by reference numeral 109 is a locking member, and the locking member 10
9 is formed with a fitting part 111 having a shape that can be fitted into the hole 107 with the locking piece 102 inserted into the hole 107, and the fitting part 111 is formed in a shape that allows the fitting part 111 to be connected to the fitting part 111 and elastically close to each other. Deformable legs 112, 112 are formed. The legs 112, 112 normally have a width greater than the width of the hole 104. Further, the length in the longitudinal direction of the leg portions 112, 112 is the same as that of the hole 1 when a protrusion similar to the previous embodiment formed on the first contact portion 106 of the clip 105 is inserted and locked into the hole 104.
The length in the longitudinal direction is approximately equal to that of 04.

Next, the installation procedure of the embodiment shown in FIGS. 4 to 6 will be explained.

As in the previous embodiment, the protrusion of the first contact part 106 is inserted and locked into the upper end of the hole 104, the locking part 103 of the locking piece 102 is engaged with the lower end of the hole 107, First and second contact portions 10 of clip 105
6 and 108 are pressed against the outer surface of the cylinder body 101 by the own elasticity of the clip 105. Next, the fitting portion 111 of the locking member 109 is fitted into the hole 107 into which the locking piece 102 is inserted from inside the cylinder 101, so as to prevent the locking piece 102 and the hole 107 from being misaligned. do. At this time, the leg portion 11 of the locking member 109
2, 112 will be deformed by the hole 104 of the cylindrical body 104, but the leg portions 112, 112 will expand by their own elasticity in the state of coming out of the hole 104, and the end portions will be expanded by their own elasticity. It locks onto the outer surface of the cylinder 104 (see FIG. 5).

(Effects of the invention) As described above, in the present invention, the protrusion of the first contact part of the clip is inserted and locked into the hole of the cylinder, and the locking part of the locking piece is inserted into the lower end of the hole of the clip. After engaging,
By fitting the fitting part of the locking member into the hole of the clip with the locking piece inserted, the clip can be securely attached to the cylinder, and the clip is only inserted and locked into the hole of the cylinder. Since the first abutting part is also the same depth as or less than the depth of the hole, it does not protrude into the cylindrical body, so that it is possible to eliminate as much as possible obstacles in arranging the mechanism part within the cylindrical body. Further, according to the present invention, the locking member can be colored for decoration, or the exposed portion of the locking member can be engraved or a sticker can be attached to the locking member to use it as an indicator. You can expect it.
