（産業上の利用分野）
本考案は筆記具用クリツプに関するものであ
る。[Detailed Description of the Invention] (Field of Industrial Application) The present invention relates to a writing instrument clip.
（従来技術とその問題点）
筆記具用クリツプとして種々知られる中にあつ
て、第７図に示す如くの形態のクリツプがある。(Prior art and its problems) Among the various types of clips for writing instruments known, there is a clip of the form shown in FIG.
該クリツプ１０１は、軸筒に嵌合し得る断面Ｃ

の対向する２片を円形に折曲して嵌合部１０２を
形成し、又他片の基部を起立させて先端部の挾持
部１０４にて紙、布等を挾持するに充分な高さを
腕部１０３に付与するのみで安価に製作すること
ができることから、低価格品、高価格品を問わず
筆記具において広く採用されている。 The clip 101 has a cross section C that can fit into the shaft cylinder.
a cylindrical fitting part 102, an arm part 103 extending from a part of the fitting part 102, and the arm part 103.
and a clamping part 104 provided integrally or separately at the tip of the clip 101.In addition to being easy to attach to the shaft cylinder, such a clip 101 can be easily attached to a T-piece obtained by press working. The two opposing pieces of the letter-shaped metal plate are bent into a circular shape to form the fitting part 102, and the base of the other piece is made to stand up so that the holding part 104 at the tip is sufficient to hold paper, cloth, etc. Since it can be manufactured at low cost simply by adding height to the arm portion 103, it is widely used in writing instruments, regardless of whether they are low-priced products or high-priced products.

形を充分に支えることができなくなり、ついには
挾持部１０４での挾持力に当る腕部１０３の弾性
を損うことになりかねない。 However, in the above-mentioned clip 101, in order to provide a predetermined height to the entire arm part 103 so that the holding part 104 at the tip part securely holds paper, cloth, etc., it is necessary to extend it from the fitting part 102. Since the base portion of the arm portion 103 is made to stand up, at least one bent portion S perpendicular to the swinging direction (arrow direction) of the arm portion 103 is formed at the base portion. In addition to being inferior in rigidity to the other arm portions 103 at the stage of bending, the bent portion S is repeatedly bent.
When the arm is swung, stress tends to concentrate and metal fatigue is likely to occur.As a result, the rigidity of the bent portion S deteriorates further, making it impossible to sufficiently support the elastic deformation of the arm portion 103. Eventually, the elasticity of the arm portion 103, which corresponds to the clamping force of the clamping portion 104, may be impaired.

したものである。(Summary of the invention) The present invention uses a substantially L-shaped metal plate as a base material, and forms a fitting part that can be fitted into a shaft cylinder by leaving a part corresponding to the leg part of one piece as a base material. The gist of the writing instrument clip is a writing instrument clip formed by bending at least one part of the boundary between the two pieces to form an arm part facing the outer periphery of the fitting part and the outer surface of the shaft cylinder at a predetermined height. This prevents deterioration of rigidity due to stress concentration and metal fatigue even when the arm is swung, and the elasticity of the arm can be maintained over a long period of time.

に折曲したものであつてもよい。 1 to 4, reference numeral 1 is a clip, and the clip 1 includes a cylindrical fitting part 3 that can be fitted into the shaft cylinder 2, and a cylindrical fitting part 3 that extends from one side of the fitting part 3. a leg portion 4; an arm portion 5 bent approximately 90 degrees with respect to the leg portion 4 and facing the outer surface of the shaft cylinder 2 at a predetermined height;
It is constituted by a clamping part 6 provided at the tip of the arm part 5. In the illustrated example, the clamping part 6 is formed by drilling a hole 7 at the tip of the arm part 5 and fixing a chip 8 made of resin, metal, etc. in the hole 7. 6 may be formed by bending the tip of the arm portion 5 inward.

ようにすれば簡単に得ることができる。 As shown in Fig. 4, such a clip 1 is made by bending one piece K1 of a substantially L-shaped metal plate K obtained by press processing into a circle, leaving the part that corresponds to the leg part 2. Forming a fitting part 3, the piece K1 and the other piece
This can be easily obtained by bending the boundary part K 3 (dotted line part) with K 2 by approximately 90 degrees.

に奏せられること勿論である。(Effects of the invention) As described above, according to the invention, the leg extending from the fitting part and the arm bent with the leg have a direction perpendicular to the swinging direction of the arm as in the conventional art. Since there is no bending part to bend, even when the arms are repeatedly swung, stress can be concentrated and the deterioration of rigidity caused by metal fatigue can be prevented as much as possible. can be suitably maintained. Of course, such an effect can be similarly achieved even when the bending directions of the arm portion and the fitting portion are not on the same side with respect to the leg portion.
