以下、本発明に係る実施形態を、図面を参照して説明する。ただし、本発明の範囲は、図示例に限定されるものではない。
まず、本実施形態における花留め1の構成を説明する。
図1は、実施形態における花留め1の斜視図である。
図2は、花留め1を例示する六面図である。図2(A)は平面図、図2(B)は底面図、図2(C)は正面図、図2(D)は右側面図である。なお、背面図は、正面図と対称につき省略し、左側面図は、右側面図と対称につき省略する。

Hereinafter, embodiments according to the present invention will be described with reference to the drawings. However, the scope of the present invention is not limited to the illustrated examples.
First, the configuration of the flower clasp 1 in the present embodiment will be described.
FIG. 1 is a perspective view of the flower clasp 1 in the embodiment.
FIG. 2 is a six-view view illustrating the flower clasp 1. 2 (A) is a plan view, FIG. 2 (B) is a bottom view, FIG. 2 (C) is a front view, and FIG. 2 (D) is a right side view. The rear view is omitted because it is symmetrical with the front view, and the left side view is omitted because it is symmetrical with the right side view.
FIG. 3 is an end view illustrating the AA line cut portion of the flower clasp 1 illustrated in FIG.

図1及び図2に例示するように、花留め1は、銅合金鋳物で構成された鋳物であり、砂型鋳造により形成されている。花留め1は、花留め本体10と、貫通孔20とを有する。
花留め本体10は、銅又は銅を主成分とする金属(銅合金)の鋳物で構成された花留め1の本体である。花留め本体10は、円柱、又は、角柱の形状である。すなわち、花留め本体10は、柱体の形状である。
また、花留め本体10は、金属光沢を放つよう、側面、天面、及び、底面が全面にわたって研磨されている。即ち、花留め本体10は、天面及び底面の少なくとも一部が研磨されている。ここで、本例における花留め本体10の天面とは、図2(A)に例示した花留め本体10の端面を示し、花留め本体10の底面とは、図2(B)に例示した花留め本体10の端面を示す。
また、花留め本体10の大きさは、例えば直径5cm以上7cm以下、かつ、厚み2cm以上4cm以下の大きさであり、本例の花留め本体10は、直径6cm以上6.5cm以下以下、かつ、厚み2.5cmの大きさに形成される。
As illustrated in FIGS. 1 and 2, the flower clasp 1 is a casting made of a copper alloy casting, and is formed by sand casting. The flower retainer 1 has a flower retainer main body 10 and a through hole 20.
The flower clasp main body 10 is the main body of the flower clasp 1 made of copper or a metal (copper alloy) casting containing copper as a main component. The flower retaining body 10 is in the shape of a cylinder or a prism. That is, the flower retaining body 10 has a pillar shape.
Further, the side surface, the top surface, and the bottom surface of the flower retaining body 10 are polished over the entire surface so as to give off a metallic luster. That is, at least a part of the top surface and the bottom surface of the flower retaining body 10 is polished. Here, the top surface of the flower retaining body 10 in this example indicates the end surface of the flower retaining body 10 illustrated in FIG. 2 (A), and the bottom surface of the flower retaining body 10 is exemplified in FIG. 2 (B). The end face of the flower retaining body 10 is shown.
The size of the flower retaining body 10 is, for example, a diameter of 5 cm or more and 7 cm or less and a thickness of 2 cm or more and 4 cm or less, and the flower retaining body 10 of this example has a diameter of 6 cm or more and 6.5 cm or less and a diameter of 6 cm or more and 6.5 cm or less. , 2.5 cm thick.

貫通孔20は、図2及び図3に例示したように、円柱の形状である花留め本体10に複数設けられ、天面から底面まで貫通した孔である。貫通孔20は、図2(B)に例示した底面に位置する貫通孔の開口の大きさより、図2(A)に例示した天面に位置する貫通孔の開口の大きさの方が大きい。具体的には、図3に例示した貫通孔20A〜20Dに着目すると、天面に位置する貫通孔の開口幅Dは、底面に位置する貫通孔の開口幅dより広く形成されており、貫通孔20は、天面及び底面の開口を接続するように、天面から底面に向かって徐々に狭まっている。また、隣り合う2つの貫通孔20の間に位置する壁面の厚みは、天面から底面に向かって徐々に厚くなっている。
また、貫通孔20の壁面22は、平らでない凹凸のある表面となっている。貫通孔20の壁面22は、砂型鋳造で使用した砂の粒径に応じた表面粗さとなっており、未研磨である。そのため、貫通孔20の壁面22は、研磨された花留め本体10の天面、底面、及び側面よりも粗い表面となっている。なお、貫通孔20の壁面22は、砂型に使用する砂の粒径に応じて、表面粗さを適宜変更することができる。壁面22は、表面を粗くすることにより表面積を大きくしている。
As illustrated in FIGS. 2 and 3, a plurality of through holes 20 are provided in the flower retaining body 10 having a cylindrical shape, and are holes that penetrate from the top surface to the bottom surface. In the through hole 20, the size of the opening of the through hole located on the top surface illustrated in FIG. 2 (A) is larger than the size of the opening of the through hole located on the bottom surface illustrated in FIG. 2 (B). Specifically, focusing on the through holes 20A to 20D illustrated in FIG. 3, the opening width D of the through hole located on the top surface is formed wider than the opening width d of the through hole located on the bottom surface, and the through hole is formed. The hole 20 is gradually narrowed from the top surface toward the bottom surface so as to connect the openings on the top surface and the bottom surface. Further, the thickness of the wall surface located between the two adjacent through holes 20 gradually increases from the top surface to the bottom surface.
Further, the wall surface 22 of the through hole 20 has an uneven surface that is not flat. The wall surface 22 of the through hole 20 has a surface roughness corresponding to the particle size of the sand used in the sand casting, and is unpolished. Therefore, the wall surface 22 of the through hole 20 has a rougher surface than the top surface, the bottom surface, and the side surface of the polished flower retaining body 10. The surface roughness of the wall surface 22 of the through hole 20 can be appropriately changed according to the particle size of the sand used for the sand mold. The surface area of the wall surface 22 is increased by roughening the surface.

次に、使用状態における花留め1を説明する。
図4は、植物Pを生けた状態の花留め1を例示する図である。図4(A)は、植物Pを生けた状態の花留め1を例示する斜視図であり、図4(B)、植物Pを生けた状態の花留め1の断面図である。
図4(A)に例示するように、花留め1は、水を張った花器Vに、水に沈めた状態で配置される。そして、花留め1は、植物Pを立てた状態で固定している。花留め1は、水に沈めた状態で配置することにより、銅が水中に溶出する。これにより、花留め1は、水中に溶出した銅(いわゆる銅イオン)の殺菌作用により、雑菌の繁殖を防止することができる。よって、植物Pを長持ちさせることができる。また、貫通孔20は、未研磨で粗い壁面22であるため、水と接触する面積を大きくすることができる。これにより、花留め1は、水中に高濃度の銅イオンを溶出させやすい。
Next, the flower clasp 1 in the used state will be described.
FIG. 4 is a diagram illustrating a flower clasp 1 in a state where the plant P is alive. FIG. 4 (A) is a perspective view illustrating the flower retainer 1 in the state where the plant P is alive, and FIG. 4 (B) is a cross-sectional view of the flower retainer 1 in the state where the plant P is alive.
As illustrated in FIG. 4A, the flower clasp 1 is placed in a vase V filled with water in a state of being submerged in water. Then, the flower clasp 1 is fixed in a state where the plant P is upright. By arranging the flower clasp 1 in a state of being submerged in water, copper is eluted into the water. As a result, the flower retainer 1 can prevent the growth of various germs by the bactericidal action of copper (so-called copper ion) eluted in water. Therefore, the plant P can be made to last for a long time. Further, since the through hole 20 is an unpolished and rough wall surface 22, the area in contact with water can be increased. As a result, the flower retainer 1 tends to elute high-concentration copper ions into water.

また、図4(B)に例示するように、植物Pの基端は、植物Pの基端Aのように、植物Pの基端を折り曲げた状態、又は、植物Pの基端Bのように、植物Pの基端を折り曲げず真っ直ぐな状態で、貫通孔20に挿入されている。植物Pの基端を、天面から底面に向かって貫通孔20に押し込みながら挿入すると、植物Pは、天面から底面に向かって徐々に狭くなる貫通孔20の壁面22により次第に、植物Pの基端を圧迫され挟まれる。これにより、花留め1は、植物Pを立てた状態で固定できる。このとき、植物Pの基端は、貫通孔20の壁面22の凹凸と引っ掛かるため、花留め1は、より強固に植物Pを固定できる。 Further, as illustrated in FIG. 4 (B), the base end of the plant P is such that the base end of the plant P is bent like the base end A of the plant P, or the base end B of the plant P. In addition, the base end of the plant P is inserted into the through hole 20 in a straight state without being bent. When the base end of the plant P is inserted while being pushed into the through hole 20 from the top surface to the bottom surface, the plant P is gradually narrowed from the top surface to the bottom surface by the wall surface 22 of the through hole 20. The base end is pressed and pinched. As a result, the flower clasp 1 can be fixed in a standing state of the plant P. At this time, since the base end of the plant P is caught by the unevenness of the wall surface 22 of the through hole 20, the flower retainer 1 can fix the plant P more firmly.

次に、実施形態における花留め1の製造方法を説明する。
図5は、実施形態における花留め1の製造方法(S10)を例示するフローチャートである。
図5に例示するように、ステップ100(S100)において、製造者は、砂で成形した鋳型に、溶かした銅合金を流し込む。
ステップ102(S102)において、鋳型に流し込んだ銅合金が冷えて固まった後に、製造者は、鋳型から花留め本体10を取り出す。取り出した花留め本体10は、貫通孔20が設けられた柱体形状となっている。製造者は、取り出した花留め本体10から砂を落とし、湯口やバリを除去する。
ステップ104(S104)において、製造者は、花留め本体10の表面のうち、花留め本体10の側面、天面及び底面のみを全面にわたって、金属光沢ができるまで研磨する。即ち、製造者は、花留め本体10の表面のうち、貫通孔20の壁面22を除いた領域を、金属光沢ができるまで研磨する。これにより、花留め1の意匠性を向上させると共に、使用時における使用者の手指の怪我を防止することができる。また、花留め本体10の天面及び底面を研磨することにより、花器Vの盛る面や植物Pの傷防止とすることができる。そして、製造者は、花留め1を得ることができる。
Next, a method of manufacturing the flower clasp 1 in the embodiment will be described.
FIG. 5 is a flowchart illustrating the method (S10) for manufacturing the flower clasp 1 in the embodiment.
As illustrated in FIG. 5, in step 100 (S100), the manufacturer pours the melted copper alloy into a mold molded from sand.
In step 102 (S102), after the copper alloy poured into the mold has cooled and solidified, the manufacturer removes the flower retaining body 10 from the mold. The flower retaining body 10 taken out has a pillar shape provided with a through hole 20. The manufacturer removes sand from the taken-out flower retaining body 10 to remove sprues and burrs.
In step 104 (S104), the manufacturer polishes only the side surface, the top surface, and the bottom surface of the flower retaining body 10 among the surfaces of the flower retaining body 10 until a metallic luster is formed. That is, the manufacturer polishes the area of the surface of the flower retaining body 10 excluding the wall surface 22 of the through hole 20 until metallic luster is obtained. This makes it possible to improve the design of the flower clasp 1 and prevent the user's fingers from being injured during use. Further, by polishing the top surface and the bottom surface of the flower retaining body 10, it is possible to prevent scratches on the surface on which the vase V is piled up and the plant P. Then, the manufacturer can obtain the flower clasp 1.

以上説明したように、本実施形態における花留め1によれば、銅合金の鋳物で構成することにより、植物を生けた水中に銅イオンを含有させることができる。これにより、水中における雑菌の繁殖を防止することができるため、植物を長持ちさせることができる。 As described above, according to the flower clasp 1 in the present embodiment, copper ions can be contained in the water in which the plant is alive by forming the casting of the copper alloy. As a result, it is possible to prevent the growth of various germs in water, so that the plant can last a long time.

なお、本実施形態において、貫通孔20の軸方向が花留め本体10の天面及び底面に対して略垂直となるように、貫通孔20を形成する場合を説明したが、貫通孔20の軸方向が花留め本体10の天面及び底面に対して傾斜するように、貫通孔20を形成してもよい。
また、本実施形態において、銅合金の鋳物で花留め本体10を構成する場合を説明したが、例えば、抗菌性のない金属で構成した鋳物や陶器で花留め本体10を形成し、この花留め本体10の表面に、抗菌性のある金属の皮膜を形成してもよい。抗菌性のある金属として、例えば、錫、銅、銀等が挙げられる。
In the present embodiment, the case where the through hole 20 is formed so that the axial direction of the through hole 20 is substantially perpendicular to the top surface and the bottom surface of the flower retaining body 10 has been described. The through hole 20 may be formed so that the direction is inclined with respect to the top surface and the bottom surface of the flower retaining body 10.
Further, in the present embodiment, the case where the flower retaining body 10 is composed of a copper alloy casting has been described. For example, the flower retaining body 10 is formed of a casting or pottery made of a metal having no antibacterial property, and the flower retaining body 10 is formed. An antibacterial metal film may be formed on the surface of the main body 10. Examples of the antibacterial metal include tin, copper, silver and the like.
