Description

[Detailed Description of the Invention] The present invention relates to a structure for attaching a plate clip to a writing instrument.

Traditionally, to attach a plate clip to a writing instrument,
They were caulked or tightened with crowns, but the structure was complicated or the assembly was complicated.

The present invention provides a structure for attaching a plate clip to a writing instrument in which the plate clip and the cap or barrel of the writing instrument are very easily engaged and the plate clip is securely locked.

The present invention will be described below based on embodiments shown in the drawings.

As shown in FIGS. 1 and 2, the plate clip 1 has a presser protrusion 11 protruding from its tip, and a cap 2.
Alternatively, the writing instrument is held by holding the pocket end or the like between the barrel and the barrel. The plate clip 1 extends upward from the protrusion 11 toward the top of the writing instrument and along the side surface, and its head is bent to form an insertion arm 12 forming a surface substantially perpendicular to the axial direction of the writing instrument. The insertion arm 12 has a locking hole 1
Drill 3. The top portion 21 of the cap 2 includes an insertion arm 12 for inserting the insertion arm 12 into the side wall 22.
An insertion hole 23 having substantially the same shape as the cross section is bored. Then, an engagement protrusion 25 that engages with the locking hole 13 is provided in a protruding manner on the seat 24 inside thereof. The engaging protrusion 25 has at least a back portion standing upright in the axial direction of the writing instrument so as to engage with the locking hole 13, and is provided to protrude in the axial direction of the writing instrument. In order to facilitate the engagement between the locking hole 13 and the engagement protrusion 25, the tip of the insertion arm 12 is bent at an angle, and the insertion arm 12 is once aligned with the engagement protrusion 2 while facing the insertion direction.
An engagement guide surface 14 for riding on the insertion arm 12 is provided, and the engagement projection 25 is also provided with an engagement guide surface 26 that is inclined so as to receive the tip of the insertion arm 12. The top of the cap 2 is covered with a crown 27.

To attach plate clip 1 to cap 2,
The insertion arm 12 is inserted into the insertion hole 23 from the tip of the insertion arm 12. In this embodiment, since the tip of the insertion arm 12 is bent at an angle, the insertion arm 12 is inserted while tilting up and down according to the angle. When the engagement guide surface 14 reaches the engagement protrusion 25, it comes into contact with the engagement guide surface 26, guides each other, and the insertion arm 12 rides on the engagement protrusion 25. If it is further inserted, when the positions of the locking hole 13 and the engagement protrusion 25 match, they will fit together.
A plate clip 1 is attached to a cap 2. In short, insert the insertion arm 12 of the plate clip 1 into the cap 2.
When inserted into the insertion hole 23 and pushed in, the locking hole 13 and the engagement protrusion 23 will naturally engage with each other as the inner edge of the locking hole 13 will catch on the back of the engagement protrusion 23 and will not come out. 1 is attached to cap 2.

3 and 4 respectively show other embodiments, in which the head of the plate clip 1a is bent and one side of the tip of the insertion arm 12a in which the locking hole 13a is bored is chamfered. In this embodiment, an engagement guide surface 14a is provided. According to this embodiment, since the tip of the insertion arm 12a is not bent, insertion into the insertion hole is facilitated. Further, in FIG. 4, the engaging protrusion 25a is square-shaped, and the locking hole of the plate clip is also square-shaped accordingly. According to this embodiment, since the plate clip cannot rotate about the engagement protrusion 25a, the engagement is ensured.

Note that the engagement guide surface does not need to be provided on both the plate clip side and the cap side, and may be provided on only one side.

According to the plate clip attachment structure of the writing instrument according to the present invention, it can be attached extremely easily by simply inserting the insertion arm of the plate clip into the insertion hole of the cap or barrel, and the structure is simple, so it can be attached firmly and reliably. be able to. In addition, since the plate clip can be attached regardless of the crown, for example, if writing instruments are classified by color display on the crown, it is possible to classify them in an easy-to-handle state before attaching the plate clip and then attach the crown. You can also do that.
