JPH01195100A - Method of fitting decorative piece to clip for writing implement - Google Patents

Abstract

PURPOSE:To ensure easy and secure fitting of a decorative piece to a clip for a writing implement without any limitation of the material of the clip, by inserting a guide part of the decorative piece into a small fitting hole and a large fitting hole provided in the clip, drawing out the guide part to fasten an expanded part of the decorative piece to a fastening stepped part of the large fitting hole, and then cutting off the guide part from the expanded part. CONSTITUTION:At the time of fitting a decorative piece A to a clip B for a writing implement, guide parts 4 on the back side of the decorative piece 1 are inserted into small fitting holes 6 and large fitting holes 7, and are drawn in the direction of arrows. Expanded parts 2 are immediately brought into collision with fastening stepped parts 8 provided at upper parts of the holes 7. Since the expanded parts 2 have appropriate elasticity, however, further strong pulling of the guide parts 4 cause the expanded parts 2 to contract in diameter and pass through the fastening stepped parts 8 of the holes 7, after which the expanded parts 2 are restored to the initial shape thereof, whereby the parts 2 are fastened to the stepped parts 8. Next, the guide parts 4 protruding from the expanded parts 2 are cut off by a cutter or the like, whereby the desired clip for the writing implement can be obtained.

Description

DETAILED DESCRIPTION OF THE INVENTION [Industrial Field of Application] The present invention relates to several methods for securely attaching a decorative piece to the gripping portion of a writing instrument clip.

[Prior art] Decorative pieces in writing instrument clips are mainly used to improve the appearance design effect, indicate the color of the ink used, and to display the manufacturer's name,
It is attached to the holding part for the purpose of advertising the product name, etc., but since this type of decorative piece is usually made of a molded body of synthetic resin, etc., it can be attached by appropriate means such as gluing, welding, or uneven fitting. By using it, it can be easily attached to the clip for the commode storage device.

In addition to the above-mentioned materials, there are also materials made of rubber-like elastic materials such as silicone rubber, but in this case, if the above-mentioned methods are used to attach them, the following problems may occur. there were.

[Problems to be solved by the invention] That is, when it comes to adhesion, there are problems such as poor appearance due to adhesive extrusion and decrease in adhesive strength over time, and when it comes to welding, the melting point of the clip material is higher than that of the decorative piece material. Because the melting point of the decorative piece is required to be higher than the melting point of This raises another problem, such as increasing the strength and making the installation process extremely difficult.In any case, there is room for improvement in the method of attaching decorative pieces made of elastic material.

[Means for Solving the Problems] The present invention has been made based on the above-mentioned circumstances, and the present invention is not subject to any particular restrictions on the number of clips to be used, and the installation work is simple and easy to install. The purpose of this article is to provide a method for attaching a decorative piece to a writing instrument clip.

That is, the present invention comprises a decorative part, a mounting protrusion having an enlarged portion on the back surface of the decorative part, and a guide part with a small diameter at the tip of the protrusion, and at least the mounting protrusion and the guide part are made of an elastic material. a writing instrument clip, which has a mounting hole in its holding part, which has several small holes and a locking step for locking the enlarged part of the mounting protrusion of the decorative piece; Inserting the guide part of the decorative piece into the small hole and the large mounting hole of the writing instrument clip and pulling the guide part to lock the enlarged part of the decorative piece to the locking step of the large mounting hole, The gist of the present invention is a method for making a decorative single claw for a writing instrument clip, which is characterized in that the guide portion is then cut out from the ampulla.

[Function] Insert the guide part of the decorative piece into the small mounting hole and large mounting hole of the writing instrument clip, and by pulling this guide part, the large part of the mounting protrusion connected to the guide part is engaged with the large mounting hole. This is passed through the stopper part and then locked, and the guide part is then cut out, so it can be secured without gluing ('4I attachment, etc.).
Moreover, the decorative piece can be easily attached to the writing instrument clip.

[Example] In the following, a method for attaching a decorative piece to a writing instrument clip according to the present invention will be described with reference to the accompanying drawings.

1 to 5 show a first embodiment of the present invention, and reference numeral A is a decorative piece made of an elastic material such as silicone rubber or NBR (21-libutadiene rubber). , a decorative portion 1 and a plurality of protrusions 83 having enlarged portions 2 are provided on the back surface of the decorative portion 1 (two in the figure), and a tip of the attachment protrusion 3 is provided with an appropriate length. A guide portion 4 having a small diameter is integrally arranged. Reference numeral B designates a writing instrument clip made of resin, metal, etc., and having a gripping part 5 for gripping clothing, etc., and the clip B has a holding part 5 with the above-mentioned decorative piece A attached thereto.
A small mounting hole 6 and a large mounting hole 7 connected to the small mounting hole 1 are bored corresponding to the positions and numbers of the mounting protrusions 3, and in the upper part of the large mounting hole 7. teeth,
An annular locking step 8 for locking the enlarged portion 2 is provided in a protruding manner.

In order to attach the decorative piece A to the writing instrument clip B, as shown in FIG. Pull this guide part 4 in the direction of the arrow.

At this time, the ampulla 2 immediately collides with the locking step 8 at the top of the manhole 7 (see Figure 3).
has appropriate elasticity, so if the guide part 4 is pulled further, the enlarged part 2 is reduced in diameter (see Fig. 4), and the fifth part is reduced in diameter.
As shown in the figure, the enlarged part 2 passes through the locking step part 8 of the large hole 7, and after this, the enlarged part 2 restores to its original shape and is locked to the locking step part 8. Become. Next, if the guide portion 4 protruding from the ampulla 2 is cut out using a cutter or the like,
A desired writing instrument clip can be obtained.

(See Fig. 2) Fig. 6 shows a second embodiment of the present invention, which differs from the first embodiment in that the decorative piece A has a decorative part 1 and an enlarged part 2. The projection 3 and the guide part 4 are constructed as separate parts A], and the mounting protrusion 83 having the guide part 2 and the guide j'
? In order to facilitate the removal of the guide portion 4 protruding from the ampullae 2 in the final step,
Although the notch 4a is provided at the boundary between the enlarged portion 2 and the guide portion 4, instead of this notch 4a, it is also possible to adopt a method of making the portion thinner.

[Effects of the Invention] As explained below, according to the present invention, it is possible to reliably and easily attach a decorative piece to a writing instrument clip made of various materials, and the appearance and design effects of the clip are improved. It has excellent advantages such as being able to improve the performance as much as possible.
