Description

[Detailed Description of the Invention] "Industrial Application Field" The present invention relates to a writing instrument clip that is easy to assemble.

``Prior art'' In conventional clips, a ring-shaped clamped part is formed on the head of the clip body, and this clamped part is clamped between the crown and the shaft body, or is inserted into the head of the clip body. It was common to have a cylinder and fit it in and glue it.

However, such conventional clips require a crown or adhesive, making it difficult to assemble the clip and requiring a large number of man-hours. In addition, when a writing instrument is placed in a pocket, the cloth in the pocket is held between the clip and the shaft, but since this is the only place that is held, there is a problem that the holding force is weak and unstable. It was hot.

``Purpose of the invention'' The present invention was made by paying attention to these conventional problems, and it enables the insertion tube of the clip body to engage with the shaft of the writing instrument, and also makes it possible to connect the clip and the shaft. It is an object of the present invention to provide a clip for a writing instrument that solves the above-mentioned problems by being able to clamp the cloth in a pocket at other locations in addition to between the pockets.

"Structure of the invention" In order to achieve the above object, in the present invention, a pair of parallel slits are bored in the axial direction at the tip of a hollow cylindrical fitting tube, and a spring-acting spring having an engaging protrusion between the slits is provided. A clip main body is formed on the head of the fitting tube and extends parallel to the axial direction in opposition to the fitting piece, and the fitting tube is fitted into the shaft body and The engagement protrusion is engaged with the engagement hole drilled in the body to lock it, and the engagement protrusion protruding outward from the shaft body is brought into elastic contact with the inner surface of the clip body, and the tip side of the writing instrument is moved beyond the engagement protrusion. This is a writing instrument clip in which a presser protrusion is formed on the clip body that is biased toward the inside and faces inward, and the presser protrusion and the outer surface of the shaft come into contact with or come close to each other. The clip is locked when the engaging protrusion engages with the engaging hole of the shaft, and there is a gap between the holding protrusion of the clip body and the shaft, and between the engaging protrusion protruding outward from the shaft and the clip body. The pocket cloth is sandwiched between the pocket cloth and the inner surface of the pocket cloth.

“Embodiment” An embodiment of the present invention will be described below based on the drawings.

1 and 2 show an embodiment of the present invention.

The clip is attached by fitting the fitting tube 1 into the shaft body 2. In this embodiment, since the writing instrument is a knock-type sharp pencil, the fitting tube 1 is attached to the clip.
The head 11 of is open. The outer diameter of the fitting tube 1 is approximately the same as the inner diameter of the shaft body 2.

An engagement piece 3 is formed at the tip 12 of the fitting tube 1, and a clip body 4 extends from the head 11, facing the engagement piece 3 and extending approximately parallel to the axial direction around the outer periphery of the shaft body. There is.

That is, a pair of parallel slits 13, 13 are bored in the tip 12 of the insertion tube 1, and a half-piece-shaped engagement piece with a spring action centered on the base 31 is inserted between the parallel slits 13, 13. 3 is formed, and an engaging protrusion 32 protruding outward is provided at the tip of the engaging piece 3. The tip of the engagement protrusion 32 protrudes to the outside of the shaft body 2 in the attached state and comes into elastic contact with the inner surface of the clip body 4.

On the other hand, an engagement hole 21 is bored in the outer wall of the shaft body 2, with which the engagement protrusion 32 of the engagement piece 3 engages in the attached state.

The clip body 4 has an engaging protrusion 32 of the engaging piece 3.
A presser projection 41 is provided that is deviated more toward the tip end 5 side of the writing instrument and projects inward. The presser protrusion 41 is set so as to come into contact with the outer surface of the shaft body 2 or to be close enough to hold the pocket cloth in the attached state.

To attach the clip having the above structure, it is inserted into the shaft body 2 from the tip end 12 of the insertion tube 1. Since the engagement protrusion 32 of the engagement piece 3 protrudes larger than the outer diameter of the fitting tube 1, it interferes with the edge of the shaft body 2, but the engagement piece 3 swings around the base 31 due to the action of the spring. When the fitting tube 1 is strongly pushed in, the engagement protrusion 32 is bent and retracted into the outer diameter of the fitting tube 1, allowing the fitting tube 1 to be deeply inserted.

When the fitting cylinder 1 is fully inserted, the engagement protrusion 32 and the engagement hole 21 of the shaft body 2 are aligned, so the engagement protrusion 32 that is urged outward will automatically engage the engagement hole 2.
The tip of the engaging protrusion 32 protrudes from the outer surface of the shaft body 2 and comes into elastic contact with the inner surface of the clip body 4. As a result, the clip body 4 extends axially along the outer surface of the shaft body 2, and the presser projection 41 is in close proximity to or in contact with the outer surface.

As you can see in Figure 1, the clip body 4 and the shaft body 2
The holding protrusions 41 of the clip main body 4 and the engaging protrusions 32 of the engaging piece 3 are arranged in alternate directions and sandwich the fabric of the pocket 6 at two places in the gap between the two parts, so that the fabric of the pocket 6 is alternately folded and bent. and is strongly clamped.

"Effects of the invention" According to the writing instrument clip of the invention, the clip can be assembled by simply fitting the insertion tube into the shaft, and no crown or adhesive is required, reducing the number of assembly steps. At the same time, the number of parts is reduced and costs can be significantly reduced. Since the fitting tube is in contact with the shaft body over a wide area and does not tilt, the clip body is held securely and durability is improved. moreover,
Since the head of the fitting tube can be used as a crown, the structure is simplified and a writing instrument with good appearance quality can be obtained.
