Description

衣服用ハンガー及び衣服用ハンガーの製造方法Clothes hanger and method for manufacturing clothes hanger
　本発明は、衣服用ハンガー及び衣服用ハンガーの製造方法に関する。 The present invention relates to a clothes hanger and a method for manufacturing a clothes hanger.
　従来、百貨店などで使用される高級なハンガーは木製であるが、安価なハンガーとして、樹脂製のハンガーが使用されている（例えば、特許文献１）。 Conventionally, high-quality hangers used in department stores and the like are made of wood, but resin hangers are used as inexpensive hangers (for example, Patent Document 1).
特許５５４４５９０号公報Japanese Patent No. 5544590
　ハンガーの基本的な機能は、衣類を効率的に保管したり、衣類のしわや型崩れを防ぐことであるが、衣服を展示販売するブティックや百貨店などにおいては、衣服をハンガーに吊るしたときの全体としての外観が、買い物客を惹きつけ、販売に影響を与える重要な要素である。一般的に、外観については、一枚の板からハンガー全体を削り出して製造する、いわゆる「一本物」が最も高級感があると言われている。ところが、「一本物」は、極めて高価であるうえに、材料を効率的に使用することができない。このため、最高級品以外の木製のハンガーの製造においては、ハンガーの本体を構成する左右の肩支持部を別々に切り出して成形した後に、中央部で貼り合わせることによって、木材を効率的に使用するようになっている。しかし、この製法の場合、中央部に合わせ目が残り、その合わせ目の上に塗料を塗布しても、時間が経過すると、やはり、その合わせ目が表面化し、外観を害する。上記文献の樹脂製のハンガーは、上記の合わせ目が存在しないように成形することができるが、扁平な構造であり、その外観は高級感を欠く。 The basic function of the hanger is to store clothes efficiently and prevent wrinkles and deformation of the clothes. However, in boutiques and department stores where clothes are displayed and sold, clothes are hung on hangers. The overall appearance is an important factor that attracts shoppers and affects sales. In general, it is said that the so-called “one piece”, which is produced by cutting the entire hanger from a single plate, has the highest quality. However, “single” is extremely expensive and the material cannot be used efficiently. For this reason, in the manufacture of wooden hangers other than the finest products, the left and right shoulder support parts that make up the hanger body are cut out separately and molded, and then bonded together at the center to efficiently use wood. It is supposed to be. However, in the case of this manufacturing method, a seam remains in the central portion, and even if a paint is applied on the seam, the seam will surface and damage the appearance as time passes. The resin hanger described in the above document can be molded so as not to have the above-mentioned joint, but has a flat structure and lacks a high-class appearance.
　本発明はかかる問題の解決を試みたものであり、木製のハンガーよりも安価であり、かつ、木製のハンガーに劣らない高級感のある衣服用ハンガー及び衣服用ハンガーの製造方法を提供することを目的とする。 The present invention is an attempt to solve such a problem, and provides a clothes hanger that is less expensive than a wooden hanger and has a high-class feeling, and a method for manufacturing a clothes hanger.

　以下、本発明を実施するための形態（以下、実施形態）について詳細に説明する。以下の説明においては、同様の構成には同じ符号を付し、その説明を省略又は簡略する。なお、当業者が適宜実施できる構成については説明を省略し、本発明の基本的な構成についてのみ説明する。 Hereinafter, modes for carrying out the present invention (hereinafter referred to as embodiments) will be described in detail. In the following description, the same reference numerals are given to the same components, and the description thereof is omitted or simplified. Note that description of configurations that can be appropriately implemented by those skilled in the art will be omitted, and only the basic configuration of the present invention will be described.
＜第一の実施形態＞
　図１及び図２に示すように、衣服用ハンガー１（以下、「ハンガー１」という。）は、フック部２と本体部４で構成されている。本体部４は、中心部４ａと、中心部４ａに対して対称に形成される肩支持部４ｂ及び４ｃがプラスチック樹脂によって一体として形成されている。中心部４ａ、肩支持部４ｂ及び４ｃは、プラスチック樹脂によって、合わせ目を有さない単一の部材として形成されている。フック部２は、中心部４ａに固定される。フック部２は金属で形成されている。 <First embodiment>
As shown in FIGS. 1 and 2, a clothes hanger 1 (hereinafter referred to as “hanger 1”) includes a hook portion 2 and a main body portion 4. The main body 4 has a central portion 4a and shoulder support portions 4b and 4c formed symmetrically with respect to the central portion 4a, which are integrally formed of plastic resin. The center portion 4a and the shoulder support portions 4b and 4c are formed of a plastic resin as a single member having no joint. The hook part 2 is fixed to the center part 4a. The hook part 2 is made of metal.
　本体部４を形成するプラスチック樹脂は、射出成型とブロー成型が可能な樹脂であり、
例えば、ポリプロピレン（ｐｏｌｙｐｒｏｐｙｌｅｎｅ）である。 The plastic resin forming the main body 4 is a resin that can be injection molded and blow molded,
For example, it is polypropylene (polypropylene).
　図３及び図４に示すように、本体部４には、中心部４ａにおいて屈曲し、一方の肩支持部４ｂの端部近傍の位置Ｐ１から他方の肩支持部４ｃの端部近傍の位置Ｐ２へ向かう空間部４ｄが形成されている。図５に示すように、空間部４ｄは、本体部の下面４ｓ１に沿って形成されており、上面４ｓ２に沿って形成されているのではない。すなわち、空間部４ｄは、本体部４の上方の領域Ｈ１には空間部４ｄは形成されておらず、下方の領域Ｈ２にのみ形成されている。 As shown in FIGS. 3 and 4, the main body portion 4 is bent at the center portion 4a, and a position P2 near the end portion of the other shoulder support portion 4c from a position P1 near the end portion of the one shoulder support portion 4b. The space part 4d which goes to is formed. As shown in FIG. 5, the space 4d is formed along the lower surface 4s1 of the main body, and is not formed along the upper surface 4s2. That is, the space 4d is not formed in the region H1 above the main body 4 and is formed only in the region H2 below.
　図５に示す本体部４の長手方向のＰ－Ｐ線断面図が図６（ａ）であり、Ｑ－Ｑ線断面図が図６（ｂ）である。Ｐ－Ｐ線断面図は肩支持部４ｂにおける断面図であり、Ｑ－Ｑ線断面図は中心部４ａにおける断面図である。中心部４ａにおける空間部４ｄの上方の壁の厚さＢ３(図６（ｂ）参照)は、肩支持部４ｂにおける空間部４ｄの上方の壁の厚さＢ１(図６（ａ）参照)よりも大きく構成されている。 FIG. 6A is a cross-sectional view taken along the line PP of the main body 4 shown in FIG. 5, and FIG. 6B is a cross-sectional view taken along the line QQ. The sectional view taken along the line PP is a sectional view at the shoulder support portion 4b, and the sectional view taken along the line QQ is a sectional view at the central portion 4a. The wall thickness B3 (see FIG. 6B) above the space portion 4d in the central portion 4a is larger than the wall thickness B1 (see FIG. 6A) above the space portion 4d in the shoulder support portion 4b. Is also made up of large.
　上述のように、中心部４ａにおいて、フック部２が固定される領域には、空間部４ｄは形成されていない。このため、フック部２は、プラスチック樹脂のみで形成されている領域Ｈ１に強固に固定される。 As described above, the space portion 4d is not formed in the region where the hook portion 2 is fixed in the central portion 4a. For this reason, the hook part 2 is firmly fixed to the area | region H1 currently formed only with the plastic resin.
　図６（ａ）に示すように、肩支持部４ｂにおいて、空間部４ｄの上方の壁の厚さＢ１は、空間部４ｄの下方の壁の厚さＢ２よりも大きい。また、図６（ｂ）に示すように、中心部４ａにおいて、空間部４ｄの上方の壁の厚さＢ３は、空間部４ｄの下方の壁の厚さＢ４よりも大きい。すなわち、本体部４の全体にわたって、空間部４ｄの上方の壁の厚さが下方の壁の厚さよりも大きいから、衣服が接することによって外力が加わる部分である上方の構造が外力に対する耐性が大きく構成されている。 As shown in FIG. 6A, in the shoulder support portion 4b, the thickness B1 of the wall above the space portion 4d is larger than the thickness B2 of the wall below the space portion 4d. As shown in FIG. 6B, in the central portion 4a, the thickness B3 of the upper wall of the space portion 4d is larger than the thickness B4 of the lower wall of the space portion 4d. That is, since the thickness of the upper wall of the space portion 4d is larger than the thickness of the lower wall over the entire body portion 4, the upper structure, which is a portion to which external force is applied by contact with clothes, has high resistance to external force. It is configured.
　図７に示すように、フック部２の上側部分は、吊下げ用のバー（図示せず）に吊り下げるための開口環状部２ｃ及び直線部２ｄで構成される。フック部２の下側部分は、複数の環状部２ｂ１が形成された直線部２ｂと拡径部２ａで構成される。環状部２ｂ１は、上側の面から下側の面に向かって傾斜している。 As shown in FIG. 7, the upper portion of the hook portion 2 is composed of an annular opening portion 2c and a straight portion 2d for hanging on a hanging bar (not shown). The lower part of the hook part 2 is composed of a straight part 2b in which a plurality of annular parts 2b1 are formed and an enlarged diameter part 2a. The annular portion 2b1 is inclined from the upper surface toward the lower surface.
　図８に示すように、フック部２は、本体部４の中心部４ａに対して、矢印Ｚ１に示す方向に差しこまれる。フック部２は、領域Ｈ１の範囲において固定される。 As shown in FIG. 8, the hook portion 2 is inserted in the direction indicated by the arrow Z <b> 1 with respect to the center portion 4 a of the main body portion 4. The hook portion 2 is fixed in the range of the region H1.
　本体部４を成形した後、本体部４を金型から取り出し、プラスチック樹脂が完全に固化する前に、フック部２を本体部４に差しこむと、図９（ａ）の断面図及び平面図に示すように、本体部４には孔Ｊ１が生じるのであるが、極めて短時間において、図９（ｂ）に示すように、拡径部２ａを含むフック部２は溶融状態のプラスチック樹脂に覆われる。フック部２を本体部４に差しこむ条件によっては、拡径部２ａの上面２ａａ（図７）において、直線部２ｄの近傍はプラスチック樹脂に覆われない場合もあるが、その場合であっても、上面２ａａの一部はプラスチック樹脂に覆われる。 After the body part 4 is molded, the body part 4 is taken out from the mold, and before the plastic resin is completely solidified, the hook part 2 is inserted into the body part 4, so that a cross-sectional view and a plan view of FIG. As shown in FIG. 9, a hole J1 is formed in the main body portion 4, but in a very short time, the hook portion 2 including the enlarged diameter portion 2a is covered with a molten plastic resin as shown in FIG. 9B. Is called. Depending on the conditions for inserting the hook portion 2 into the body portion 4, the upper surface 2aa (FIG. 7) of the enlarged diameter portion 2a may not be covered with plastic resin in the vicinity of the straight portion 2d. A part of the upper surface 2aa is covered with a plastic resin.
　あるいは、本体部４を成形した後、本体部４を金型から取り出し、プラスチック樹脂が固化した後に、フック部２をプラスチック樹脂の融点以上の温度に熱して本体部４に差しこむことによって、フック部２が本体部４を溶融状態にしつつ、本体部４の内部に入り込むことができる。いずれの場合においても、フック部２が本体部４に差しこまれた後に、直線部２ｂと拡径部２ａが溶融状態のプラスチック樹脂で覆われ、フック部２は強固に固定される。すなわち、プラスチック樹脂が固化した後において、フック部２の上面２ａａ及び下面２ａｂ（図７参照）は、プラスチック樹脂と接しているから、本体部４におけるフック部２の上下方向の位置は強固に固定される。 Alternatively, after forming the main body part 4, the main body part 4 is taken out from the mold, and after the plastic resin is solidified, the hook part 2 is heated to a temperature equal to or higher than the melting point of the plastic resin and inserted into the main body part 4. The part 2 can enter the inside of the main body part 4 while the main body part 4 is melted. In any case, after the hook portion 2 is inserted into the main body portion 4, the straight portion 2b and the enlarged diameter portion 2a are covered with a molten plastic resin, and the hook portion 2 is firmly fixed. That is, after the plastic resin is solidified, since the upper surface 2aa and the lower surface 2ab (see FIG. 7) of the hook portion 2 are in contact with the plastic resin, the vertical position of the hook portion 2 in the main body portion 4 is firmly fixed. Is done.
　以下、図１０乃至図１３を参照して、本体部４の製造方法を説明する。本体部４を成型するために、図１１に示すように、一対の部材２００Ａ及び２００Ｂから構成される金型を使用する。部材２００Ａ及び２００Ｂは、部材２００Ｂが図１２（ａ）の矢印Ｂ１方向に移動することによって、図１２（ｂ）に示すように一体となり、本体部４の形状をしたキャビティ（図１０（ａ）参照）を形成する。図１１等に示す金型は、本体部４を同時に２個成形することができる。部材２００Ａの凹部２００Ａ１と部材２００Ｂの凹部２００Ｂ１が一体となり、部材２００Ａの凹部２００Ａ２と部材２００Ｂの凹部２００Ｂ２が一体となり、それぞれ、本体部４の形状をしたキャビティを形成する。 Hereinafter, the manufacturing method of the main body 4 will be described with reference to FIGS. 10 to 13. In order to mold the main body 4, as shown in FIG. 11, a mold composed of a pair of members 200 </ b> A and 200 </ b> B is used. The members 200A and 200B are integrated into a cavity as shown in FIG. 12B by moving the member 200B in the direction of arrow B1 in FIG. 12A (see FIG. 10A). Reference). The mold shown in FIG. 11 and the like can form two main body portions 4 simultaneously. The concave portion 200A1 of the member 200A and the concave portion 200B1 of the member 200B are integrated, and the concave portion 200A2 of the member 200A and the concave portion 200B2 of the member 200B are integrated to form a cavity having the shape of the main body portion 4, respectively.
　図１２（ｂ）に示すように、部材２００Ａ及び２００Ｂによって、本体部４の形状をしたキャビティが形成されると、図１３（ａ）に示すように、樹脂吐出口２０２からキャビティ内にプラスチック樹脂が射出され、充填される（図１０（ｂ）参照）。 When the cavity having the shape of the main body 4 is formed by the members 200A and 200B as shown in FIG. 12B, a plastic resin is introduced into the cavity from the resin discharge port 202 as shown in FIG. Are injected and filled (see FIG. 10B).
　キャビティにプラスチック樹脂が充填されると、プラスチック樹脂が固化する前に、図１３（ｂ）に示すように、気体ノズル２０４から気体を噴射し、矢印Ｓ１に示すように、プラスチック樹脂内を通過させる。気体は、大気圧よりも高い圧力を有する気体である。気体は、例えば、窒素（Ｎ２）であり、圧力は大気圧の数倍であり、例えば、５気圧である。プラスチック樹脂内を気体が通過することによって、図１０（ｃ）に示すように、プラスチック樹脂が外側（矢印Ｖ１方向）に広がり、キャビティの内面に押し付けられる。これにより、図１０（ｄ）に示すように、本体部４の製造が完了する。気体が通過した通路は、本体部４において、空間部４ｄとなる。プラスチック樹脂の充填態様と気体の圧力を調整することによって、空間部４ｄの体積を調整することができ、ハンガー１の重量を調整することができる。 When the cavity is filled with plastic resin, before the plastic resin is solidified, gas is injected from the gas nozzle 204 as shown in FIG. . A gas is a gas having a pressure higher than atmospheric pressure. The gas is, for example, nitrogen (N 2 ), and the pressure is several times the atmospheric pressure, for example, 5 atmospheres. When the gas passes through the plastic resin, as shown in FIG. 10C, the plastic resin spreads outward (in the direction of arrow V1) and is pressed against the inner surface of the cavity. Thereby, as shown in FIG.10 (d), manufacture of the main-body part 4 is completed. The passage through which the gas passes becomes a space portion 4 d in the main body portion 4. By adjusting the filling mode of the plastic resin and the gas pressure, the volume of the space 4d can be adjusted, and the weight of the hanger 1 can be adjusted.
　なお、気体通路の開口部を構成していた肩支持部４ｂ及び４ｃの端部は、プラスチック樹脂の成型後の収縮により、一部または全部が閉鎖される。 Note that the end portions of the shoulder support portions 4b and 4c constituting the opening portion of the gas passage are partially or entirely closed by contraction after molding of the plastic resin.
　以下、図１４を参照して、本体部４の製造方法を概括する。まず、金型２００Ｂを矢印Ｂ１（図１２参照）方向に移動させて金型２００Ａと一体化することによって金型を閉鎖し、本体部４の形状を有するキャビティを形成する（図１４のステップＳＴ１）。続いて、キャビティにプラスチック樹脂を充填する（ステップＳＴ２）。続いて、キャビティに充填したプラスチック樹脂が固化する前に、プラスチック樹脂に大気圧よりも高い圧力を有する気体を通過させ、空間部４ｄを形成する（ステップＳＴ３）。ステップＳＴ３において、プラスチック樹脂がキャビティに押し付けられ、本体部４の製造が完了する。最後に、金型２００Ｂを矢印Ｂ１とは逆の方向へ移動させ、金型を開放する（ステップＳＴ４）。 Hereinafter, the manufacturing method of the main body 4 will be summarized with reference to FIG. First, the mold 200B is moved in the direction of arrow B1 (see FIG. 12) and integrated with the mold 200A to close the mold, thereby forming a cavity having the shape of the main body 4 (step ST1 in FIG. 14). ). Subsequently, the cavity is filled with plastic resin (step ST2). Subsequently, before the plastic resin filled in the cavity is solidified, a gas having a pressure higher than atmospheric pressure is passed through the plastic resin to form the space 4d (step ST3). In step ST3, the plastic resin is pressed against the cavity, and the manufacture of the main body 4 is completed. Finally, the mold 200B is moved in the direction opposite to the arrow B1, and the mold is opened (step ST4).
＜第二の実施形態＞
　次に、図１５を参照して、第二の実施形態について説明する。なお、第一の実施形態と共通する構成については説明を省略し、第一の実施形態と異なる部分を中心に説明する。 <Second Embodiment>
Next, a second embodiment will be described with reference to FIG. In addition, description is abbreviate | omitted about the structure which is common in 1st embodiment, and it demonstrates centering on a different part from 1st embodiment.
　第二の実施形態のハンガー１Ａの本体部４には、木目が付されている。これは、図１１に示す凹部２００Ａ１、２００Ａ２、２００Ｂ１及び２００Ｂ２に木目を模した凹凸が形成されていることによる。すなわち、本体部４の製造工程の最終工程において、プラスチック樹脂がキャビティに押し付けられることによって、キャビティに付された凹凸が本体部４に写されて、本体部４に木目が形成される。これにより、ハンガー１Ａは、木製のハンガーの外観と近似する。 A wood grain is attached to the main body 4 of the hanger 1A of the second embodiment. This is because the concave and convex portions 200A1, 200A2, 200B1, and 200B2 shown in FIG. That is, in the final step of the manufacturing process of the main body part 4, the plastic resin is pressed against the cavity, whereby the unevenness applied to the cavity is copied to the main body part 4 and a grain is formed on the main body part 4. Thereby, 1 A of hangers approximate the external appearance of a wooden hanger.
＜第三の実施形態＞
　次に、第三の実施形態について説明する。なお、第二の実施形態と共通する構成については説明を省略し、第二の実施形態と異なる部分を中心に説明する。 <Third embodiment>
Next, a third embodiment will be described. In addition, description is abbreviate | omitted about the structure which is common in 2nd embodiment, and it demonstrates centering on a different part from 2nd embodiment.
　第三の実施形態においては、プラスチック樹脂に、所定の割合で木材が混入されている。木材は、木材粉であり、その混入割合は、例えば、５～３０重量パーセントである。これにより、ハンガー１Ａは、一層、木製のハンガーの外観に近似する。 In the third embodiment, wood is mixed in the plastic resin at a predetermined ratio. Wood is wood powder, and the mixing ratio is, for example, 5 to 30 weight percent. Thereby, the hanger 1A further approximates the appearance of a wooden hanger.
＜第四の実施形態＞
　次に、図１６を参照して、第四の実施形態について説明する。なお、第一の実施形態と共通する構成については説明を省略し、第一の実施形態と異なる部分を中心に説明する。 <Fourth embodiment>
Next, a fourth embodiment will be described with reference to FIG. In addition, description is abbreviate | omitted about the structure which is common in 1st embodiment, and it demonstrates centering on a different part from 1st embodiment.
　第五の実施形態のハンガー１Ｂは、アンダーバー６を有する。アンダーバー６は、衣服を吊り下げる吊り下げ部６ａと、本体部４の肩支持部の端部近傍の下部に固定される一対の固定軸部６ｂで構成される。固定軸部６ｂには、直径が拡大した拡大部６ｂａが形成されている。 The hanger 1B of the fifth embodiment has an underbar 6. The underbar 6 includes a hanging part 6 a for hanging clothes and a pair of fixed shaft parts 6 b fixed to the lower part near the end of the shoulder support part of the main body part 4. The fixed shaft portion 6b is formed with an enlarged portion 6ba having an enlarged diameter.
　アンダーバー６は、上述のフック部２と同様の方法によって、本体部４に固定される。このため、アンダーバー６が本体部４に固定されると、拡大部６ｂａの上面及び下面は、肩支持部を構成するプラスチック樹脂と接する状態となる。これにより、アンダーバー６の本体部４における上下方向の位置は強固に固定される。 The underbar 6 is fixed to the main body 4 by the same method as the hook 2 described above. For this reason, when the under bar 6 is fixed to the main body portion 4, the upper surface and the lower surface of the enlarged portion 6ba are in contact with the plastic resin constituting the shoulder support portion. Thereby, the position of the up-down direction in the main-body part 4 of the under bar 6 is firmly fixed.
＜第五の実施形態＞
　次に、図１７乃至図２１を参照して、第五の実施形態について説明する。なお、第一の実施形態と共通する構成については説明を省略し、第一の実施形態と異なる部分を中心に説明する。第五の実施形態は、第一の実施形態と、本体部４の製造に使用する金型の構造等が異なる。 <Fifth embodiment>
Next, a fifth embodiment will be described with reference to FIGS. In addition, description is abbreviate | omitted about the structure which is common in 1st embodiment, and it demonstrates centering on a different part from 1st embodiment. The fifth embodiment is different from the first embodiment in the structure of the mold used for manufacturing the main body 4.
　ハンガー１を製造するために、図１８に示すように、一対の部材２００Ａ及び２００Ｂから構成される金型を使用する。部材２００Ａ及び２００Ｂは、部材２００Ｂが図１８の矢印Ｂ１方向に移動することによって、一体となり、ハンガー１の形状をしたキャビティを形成する。図１８等に示す金型は、ハンガー１を同時に２個成形することができる。部材２００Ａの凹部２００Ａ１と部材２００Ｂの凹部２００Ｂ１が一体となり、部材２００Ａの凹部２００Ａ２と部材２００Ｂの凹部２００Ｂ２が一体となり、それぞれ、ハンガー１の形状をしたキャビティを形成する。 In order to manufacture the hanger 1, as shown in FIG. 18, a mold composed of a pair of members 200A and 200B is used. The members 200A and 200B are united when the member 200B moves in the direction of the arrow B1 in FIG. The mold shown in FIG. 18 and the like can form two hangers 1 at the same time. The concave portion 200A1 of the member 200A and the concave portion 200B1 of the member 200B are integrated, and the concave portion 200A2 of the member 200A and the concave portion 200B2 of the member 200B are integrated to form a cavity having the shape of the hanger 1, respectively.
　部材２００Ａの凹部２００Ａ１及び２００Ａ２には、それぞれ、軸部材１００Ａ及び１００Ｂが配置される。軸部材１００Ａ及び１００Ｂは、凹部２００Ａ１及び２００Ａ２の面には接していない。すなわち、軸部材１００Ａ及び１００Ｂは、ハンガー１の形状をしてキャビティが形成されたときには、キャビティ内において浮いた状態になる。 The shaft members 100A and 100B are disposed in the recesses 200A1 and 200A2 of the member 200A, respectively. The shaft members 100A and 100B are not in contact with the surfaces of the recesses 200A1 and 200A2. That is, when the shaft members 100A and 100B have the shape of the hanger 1 and the cavity is formed, the shaft members 100A and 100B float in the cavity.
　図１９に示すように、部材２００Ａ及び２００Ｂによって、ハンガー１の形状をしたキャビティが形成されると、図２０に示すように、樹脂吐出口２０２からキャビティ内にプラスチック樹脂が射出され、充填される。プラスチック樹脂は、図１７（ａ）に示すように、軸部材１００Ａ及び１００Ｂを取り巻くようにキャビティ内に充填される。 As shown in FIG. 19, when a cavity having the shape of the hanger 1 is formed by the members 200A and 200B, a plastic resin is injected from the resin discharge port 202 into the cavity as shown in FIG. . As shown in FIG. 17A, the plastic resin is filled in the cavity so as to surround the shaft members 100A and 100B.
　キャビティにプラスチック樹脂が充填されると、プラスチック樹脂が固化する前に、軸部材１００Ａ及び１００Ｂは、図１７（ａ）、図１７（ｂ）及び図２０に示すように、それぞれ、矢印Ｘ１方向、矢印Ｘ２方向に引き抜かれる。これにより、充填したプラスチック樹脂において、図１７（ｃ）に示す気体通路１００Ａｓ及び１００Ｂｓが形成される。気体通路１００Ａｓと１００Ｂｓは連続した気体通路を形成している。フック部２が固定される領域Ｈ１には、気体通路は形成されない。 When the cavity is filled with plastic resin, before the plastic resin is solidified, the shaft members 100A and 100B are moved in the direction of the arrow X1, respectively, as shown in FIGS. 17 (a), 17 (b), and 20. It is pulled out in the direction of arrow X2. Thereby, the gas passages 100As and 100Bs shown in FIG. 17C are formed in the filled plastic resin. The gas passages 100As and 100Bs form a continuous gas passage. No gas passage is formed in the region H1 where the hook portion 2 is fixed.
　続いて、図１７（ｃ）及び図２１に示すように、気体通路１００Ａｓ及び１００Ｂｓから構成される気体通路に大気圧よりも高い圧力を有する気体を通過させる。気体は、図２１の気体ノズル２０４から噴射され、矢印Ｙ１方向から入り、矢印Ｙ２方向に抜けていく。気体は、例えば、窒素（Ｎ２）であり、圧力は大気圧の数倍であり、例えば、５気圧である。プラスチック樹脂内を気体が通過することによって、図１７（ｃ）に示すように、プラスチック樹脂が外側（矢印Ｖ１方向）に広がり、キャビティの内面に押し付けられる。これにより、図１７（ｄ）に示すように、本体部４が完成する。気体通路は、本体部４において、空間部４ｄとなる。軸部材１００Ａ及び１００Ｂの太さを調整することによって、空間部４ｄの体積を調整することができ、ハンガー１の重量を調整することができる。 Subsequently, as shown in FIG. 17 (c) and FIG. 21, a gas having a pressure higher than the atmospheric pressure is passed through the gas passage composed of the gas passages 100As and 100Bs. The gas is injected from the gas nozzle 204 of FIG. 21, enters from the direction of arrow Y1, and exits in the direction of arrow Y2. The gas is, for example, nitrogen (N2), and the pressure is several times the atmospheric pressure, for example, 5 atmospheres. As the gas passes through the plastic resin, as shown in FIG. 17C, the plastic resin spreads outward (in the direction of arrow V1) and is pressed against the inner surface of the cavity. Thereby, as shown in FIG.17 (d), the main-body part 4 is completed. The gas passage is a space portion 4 d in the main body portion 4. By adjusting the thickness of the shaft members 100A and 100B, the volume of the space 4d can be adjusted, and the weight of the hanger 1 can be adjusted.
　なお、気体通路の開口部を構成していた肩支持部４ｂ及び４ｃの端部は、プラスチック樹脂の成型後の収縮により、一部または全部が閉鎖される。 Note that the end portions of the shoulder support portions 4b and 4c constituting the opening portion of the gas passage are partially or entirely closed by contraction after molding of the plastic resin.
　なお、本発明は本実施形態に限定されるものではなく、本発明の目的を達成できる範囲での変形、改良等は本発明に含まれるものである。例えば、上述の第一の実施形態乃至第五の実施形態の構成を、適宜、組み合わせてもよい。 It should be noted that the present invention is not limited to the present embodiment, and modifications, improvements, etc. within a scope that can achieve the object of the present invention are included in the present invention. For example, the configurations of the first to fifth embodiments described above may be combined as appropriate.
