【発明の属する技術分野】
本発明は、うちわに関し、特に、強度が高く、充分な寿命が得られ、且つ製造が容易なうちわに関するものである。
【０００２】

【発明が解決しようとする課題】
しかしながら、うちわは実際に使用することにより両面に大きな力がかかるが、上記のようなうちわは骨組みを有していないため、その両面方向の力に耐えがたい。よって、特に持ち手部が折れ曲がり易く充分な寿命が得られない。また持ち手部の強度を向上するために、図４に示すうちわ１００のように、持ち手部にさらに１枚の板紙１０１を貼り付けることで持ち手部の強度を向上することも考えられるが、１枚の板紙１０１を貼り付けただけの持ち手部では未だ充分な強度を有さないばかりか、却って、持ち手部と本体との境界部分に曲げ力が集中するので、その部分が折れ曲がり易くなり、充分な寿命が得られないという問題点があった。
【０００５】
本発明は上述した問題点を解決するためになされたものであり、強度が高く、充分な寿命が得られ、且つ製造が容易なうちわを提供することを目的としている。
【０００６】
【課題を解決するための手段】
この目的を達成するために請求項１記載のうちわは、板状の本体部と、その本体部の外周の一部に設けられた連結部と、その連結部を介して前記本体部と連結された把持部とを有するうちわであって、前記連結部を前記本体部に対し折り曲げ且つ前記把持部を前記連結部に対し折り曲げることにより前記把持部が前記本体部に対向する姿勢でその把持部を係止するように、前記本体部に設けられた係止部と、前記把持部が前記係止部に係止された状態の前記把持部と対向する面の側に折り曲げ可能に前記本体部に連設された本体部側厚み部と、前記把持部が前記係止部に係止された状態の前記本体部と対向する面の側に折り曲げ可能に前記把持部に連設された把持部側厚み部とを有して構成されている。
また、前記本体部側厚み部は、前記本体部に第２切込みを入れることにより前記連結部へ向かって折り曲げることができるように形成されており、前記把持部側厚み部は、前記連結部を基準として前記第２切込みと略対称である第３切込みを前記把持部に入れることにより前記連結部へ向かって折り曲げることができるように形成されている。
【０００７】
この請求項１記載のうちわによれば、把持部が係止部に係止された状態の把持部と対向する面の側に折り曲げ可能に本体部に連設された本体部側厚み部と、把持部が係止部に係止された状態の本体部と対向する面の側に折り曲げ可能に把持部に連設された把持部側厚み部とを有しているので、把持部側厚み部と本体部側厚み部とが本体部と把持部との間に挟まれた状態で、把持部が本体部に設けられた係止部に係止される。
また、第３切込みは連結部を基準として第２切込みと略対称であるので、把持部が本体部に設けられた係止部に係止された状態では、第２切込みと第３切込みが略一致する。また共に連結部へ向かって折り曲げられた本体部側厚み部と把持部側厚み部とが、本体部と把持部の間で重なる。
【０００８】
請求項２記載のうちわは、請求項１記載のうちわにおいて、前記係止部は、前記本体部に略半円の円弧状の第１切込みを入れることにより形成されるように構成されている。
【０００９】
【００１０】
【００１１】
請求項３記載のうちわは、請求項１または２に記載のうちわにおいて、前記把持部の外周は、略円弧状の円弧部を有し、前記係止部は前記把持部のうち前記円弧部の一部を係止するものであるように構成されている。
【００１２】
請求項３記載のうちわによれば、請求項１または２に記載のうちわと同様に作用する上、把持部のうち円弧部の一部を係止部に係止することによりうちわを組み立てることができる。さらに、係止部と把持部との間に働く力を一点に集中させることができる。
【００１３】
請求項４記載のうちわは、請求項１から３のいずれかに記載のうちわにおいて、前記本体部側厚み部及び前記把持部側厚み部が折り曲げられた状態で前記把持部を前記係止部に係止することにより、前記本体部側厚み部及び前記把持部側厚み部は前記本体部と前記把持部との間に挟まれた状態で少なくとも１部において互いに接触し、且つ所定の角度を持って対向するものであるように構成されている。
【００１４】
請求項４記載のうちわによれば、請求項１から３に記載のうちわと同様に作用する上、本体部側厚み部及び把持部側厚み部は本体部と把持部との間に挟まれた状態で少なくとも１部において互いに接触し、且つ所定の角度を持って対向するものであることから、本体部側厚み部と把持部側厚み部とがばねとして働き、把持部が係止部に逆らおうとする方向の力を大きくする。
【００１５】
請求項５記載のうちわは、請求項１から４のいずれかに記載のうちわにおいて、前記本体部、前記連結部、前記把持部は、切刃およびけい線を組み込んだ抜き型で打ち抜くことにより１枚の板紙から一体的に成型されるものであるように構成されている。
【００１６】
請求項６記載のうちわは、請求項１から４のいずれかに記載のうちわにおいて、前記本体部、前記連結部、前記把持部は、１枚の板状の合成樹脂からなるものであるように構成されている。
【００１７】
【発明の効果】
請求項１記載のうちわによれば、把持部が係止部に係止された状態においては、本体部と把持部との間に、本体部側厚み部及び把持部側厚み部による厚みが介挿されることとなるので、本体部、連結部、把持部が強固な三角構造をなす。よって、うちわの持ち手の部分の強度が格段に向上し、充分な寿命が得られるという効果がある。また、かかる三角構造により係止部においては把持部を係止する方向の力が常に働き、且つ把持部には係止部の係止に逆おうとする方向の力が常に働いているので、本体部には常に力が加えられ、本体部に腰を与えることになる。よって、本発明のうちわは骨組みを有さずも、本体部のたわみを抑制でき、充分な寿命が得られるという効果がある。
また、第２切込みを入れることにより本体部側厚み部が形成され、把持部に第３切込みを入れることにより把持部側厚み部が形成されるので、容易に本体部側厚み部及び把持部側厚み部を形成することができるという効果がある。また、第３切込みは連結部を基準として第２切込みと略対称であるので、把持部が本体部に設けられた係止部に係止された状態では、第２切込みと第３切込みが略一致する。よって、本体部側厚み部および把持部側厚み部を折り曲げて把持部を係止部に係止した状態では、使用者がうちわを用いる際に上記第２切込みと第３切込みに指をいれることができるようになる。第２切込みと第３切込みとは共に略円弧状に構成すれば、指を痛めることがないという効果がある。さらに、共に連結部へ向かって折り曲げられた本体部側厚み部と把持部側厚み部とが、本体部と把持部との間で重なって、本体部、連結部、把持部との間に形成される三角構造をさらに強化するので、強度が向上し、充分な寿命が得られる。
【００１８】
請求項２記載のうちわによれば、請求項１記載のうちわの奏する効果に加え、係止部が略半円の円弧状となるので、係止部を最適な形状とすることができ、強度が向上して充分な寿命が得られ、且つ容易に組み立てることができるという効果がある。係止部が略半円よりも小さい円弧状である場合には把持部を介挿することが難しく、また、係止部が略半円よりも大きい円弧状である場合には、係止部の強度が低下し、把持部の力により破れやすくなるのである。
【００１９】
【００２０】
請求項３記載のうちわによれば、請求項１または２に記載のうちわの奏する効果に加え、把持部のうち円弧部の一部を前記係止部に係止することによりうちわを組み立てることができるので、組み立てが容易であるという効果がある。さらに、係止部と把持部との間に働く力が一点に集中するため、本体部がさらに安定するという効果がある。
【００２１】
請求項４記載のうちわによれば、請求項１から３のいずれかに記載のうちわの奏する効果に加え、把持部側厚み部および本体部側厚み部は本体部と把持部との間に挟まれた状態で少なくとも１部において互いに接触し、且つ所定の角度を持って対向するものであることから、把持部側厚み部と本体部側厚み部とがばねとして働き、把持部が係止部に逆らおうとする方向の力をより大きくするので、係止部に働く力をより大きくすることができ、本体部の腰をより強くし、うちわの強度を向上することができるという効果がある。
【００２２】
請求項５記載のうちわによれば、請求項１から４のいずれかに記載のうちわの奏する効果に加え、例えば合板に切刃及びけい線を組み込んだ抜き型を用いることにより１枚の板紙から容易に成型でき、且つ、１枚の板紙のうち廃棄される部分を少なくすることができるという効果がある。
【００２３】
請求項６記載のうちわによれば、請求項１から４のいずれかに記載のうちわの奏する効果に加え、１枚の板状の合成樹脂から成型することができるので、容易に成型できるという効果がある。
【００２４】
【発明の実施の形態】
以下、本発明の好ましい実施例について、添付図面を参照して説明する。図１は本発明の実施例におけるうちわ１を示す図であり、図１（ａ）はうちわ１の正面図であり、図１（ｂ）はうちわ１の右側面図であり、図１（ｃ）はうちわ１の平面図であり、図１（ｄ）はうちわ１の背面図であり、図１（ｅ）はうちわ１の底面図である。なお、うちわ１の左側面図は図１（ｂ）の右側面図と対称である。まず、図１を参照してうちわ１の全体構成について説明する。
【００２５】
うちわ１は、略円盤状の本体部２、その本体部２の外周の一部に接し且つ一体的に設けられた矩形状の連結部３、及びその連結部３を介して本体部２に連結された略円弧状の外周形状を有する把持部４を有しており、１枚の段ボールを後述する抜き型によって打抜くことにより成型されている。
【００２６】
うちわ１の使用者は、本体部２の正面側の下部及び本体部２の背面側に対向する把持部４（図１（ｂ）の下側）を把持して支点とし、うちわ１の本体部２を正面側または背面側へあおぐことにより風を送ることができる。
【００２７】
本体部２は、略半円であって下に凸の円弧状の切込みである第１切込み５と、円周の略５／６程度であって上に凸の円弧状の切込みである第２切込み６を有している。
【００２８】
第１切込み５により本体部２に係止部７が形成される。係止部７は、本体部２の正面側から本体部２の背面側へ使用者の指などで押されることにより本体部２との間に間隙を生じさせることができ、その間隙に把持部４を介挿することができるようになる。また、把持部４を介挿した状態で使用者が係止部７を押している指を戻すと、係止部７は把持部４を本体部２との間に介挿したまま元に戻ろうとするので、係止部７は本体部２との間に把持部４を挟持することができる。
【００２９】
また、係止部７は第１切込み５と同様に略半円の円弧状の外形を有している。係止部７を略半円よりも小さい円弧状とすると係止部７を押し上げて把持部４を介挿することが難しく、また、係止部７を略半円よりも大きい円弧状とすると、係止部７の強度が低下し、把持部４の力により、第１切込み５の両端が破れやすくなるのである。
【００３０】
第２切込み６により本体部２に本体部側厚み部８が形成される。本体部側厚み部８は、使用者が指などで押すことにより把持部４が係止部７に係止された状態の把持部４と対向する面の側すなわち本体部２の正面から背面へ向けて折り曲げて連結部３側へ倒すことができるよう、図２（ａ）に太い破線で示す本体部側厚み部罫線９が設けられている。
【００３１】
連結部３は、図２（ａ）に太い破線で示すように、連結部３を本体部２に対し折り曲げることを容易にするために本体部２と連結部３との間に設けられた第１罫線１０と、把持部４を連結部３に対し折り曲げることを容易にするために連結部３と把持部４との間に設けられた第２罫線１１とを有している。
【００３２】
把持部４は、略円弧状の円弧部１２と第２罫線１１とをその外周形状に有し、図１（ｄ）のように把持部４が係止部７に係止された状態で上に凸となる略円弧状の切込みである第３切込み１３を有する。第１罫線１０において連結部３が本体部２に対して折り曲げられ、第２罫線１１において把持部４が連結部３に対して折り曲げられた状態で、把持部４の円弧部１２の一部が本体部２に設けられた係止部７に係止されることにより、図１（ａ）から（ｅ）に示す連結部３と把持部４とが折り曲げられた状態が維持される。
【００３３】
第３切込み１３により把持部４に形成される把持部側厚み部１４は、使用者が指などで押すことにより把持部４が係止部７に係止された状態の本体部２と対向する面の側すなわち把持部４の正面から背面へ向けて折り曲げて連結部３側へ倒すことができるよう、図２（ａ）に太い破線で示す把持部側厚み部罫線１５が設けられている。ここでいう把持部４の正面とは、うちわ１が組み立てられた状態で外側へ向かう面をいい、把持部４の背面とは、うちわ１が組み立てらた状態で本体部２の背面と対向する側の面をいう。
【００３４】
次に、図２を参照して、上述のように構成されたうちわ１の組み立て方法について説明する。図２は本体部２及び把持部４の背面から見た図であって、図２（ａ）は組み立て前の状態であり、図２（ｂ）は本体部側厚み部と把持部側厚み部とを折り曲げた状態であり、図２（ｃ）は把持部４を折り曲げて本体部２に対向させた状態である。図２（ａ）に示す組み立て前の状態から、本体部側厚み部８及び把持部側厚み部１４をそれぞれ本体部２の背面側及び把持部４の背面側（図２（ａ）の紙面手前側）へ折り曲げ連結部３へ向けて倒し、図２（ｂ）に示す状態とする。次に、本体部側厚み部８及び把持部側厚み部１４を倒した状態を保ちつつ、第１罫線１０において連結部３を本体部２に対して折り曲げ、第２罫線１１において把持部４を連結部３に対して折り曲げ、図２（ｃ）に示す状態とする。最後に、把持部４の円弧部１２の一部を本体部２に設けられた係止部７に係止することにより、図１に示すうちわ１を組み立てることができる。
【００３５】
このように組み立てられたうちわ１は、本体部２と把持部４とが対向した状態で第２切込み６と第３切込み１３とが略一致していて、使用者は上記第２切込み６と第３切込み１３に指をいれて、本体部２の下部と把持部４とを持ち手部とすることができることができるが、前記第２切込み６と第３切込み１３は略円弧状に形成されているため、使用者の指が痛むのを防止できる。また、持ち手部となるため特に強度が要求される本体部２の下部と把持部４においては、本体部２、連結部３、把持部４が強固な三角構造をなしているため、充分な強度が得られる。さらに、共に連結部３へ向かって折り曲げられた本体部側厚み部８と把持部側厚み部１４とが、本体部２と把持部４との間で重なって厚みを形成し、上記三角構造をさらに強化しているので、強度が向上し、充分な寿命が得られる。
【００３６】
次に、本発明のうちわ１において作用している力について、図１（ｂ）を参照して説明する。図１（ｂ）に示すように、係止部７においては係止部７が把持部４を係止する方向の力Ｆ１が常に働いている。これは、把持部４を介挿することにより常に背面側へ押圧された状態となっている係止部７に元に戻ろうとする力が働くためと考えられる。また、把持部４には前記把持部４が係止部７に逆おうとする方向の力Ｆ２が常に働いている。したがって、本体部２には常に力が加えられて緊張した状態となっており、本体部２の腰が格段に向上する。さらに、本体部側厚み部８及び把持部側厚み部１４は本体部２と把持部４との間に挟まれた状態で少なくとも１部において互いに接触し、且つ所定の角度を持って対向していることから、本体部側厚み部８と把持部側厚み部１４とがばねとして働き、把持部４が係止部７に逆らおうとする方向の力をより大きくする。
【００３７】
本発明のうちわ１は、抜き型（図示せず）により、１枚の段ボールを打ち抜くことで成型することができる。抜き型に、組み立て前のうちわ１の外形形状、第１切込み５、第２切込み６、及び第３切込み１３に対応した切れ刃と、第１罫線１０、第２罫線１１、本体部側厚み部罫線９、及び把持部側厚み部罫線１５に対応したけい線とを設けておくことにより、一度の打抜きでうちわ１を成型できる。
【００３８】
本発明のうちわ１によれば、把持部４が係止部７に係止された状態で、本体部２と把持部４との間に、本体部側厚み部８及び把持部側厚み部１４による厚みが介挿されることとなるので、本体部２、連結部３、把持部４が強固な三角構造をなす。よって、うちわ１の持ち手の部分の強度が格段に向上し、充分な寿命が得られるという効果がある。また、かかる三角構造により係止部７においては把持部４を係止する方向の力が常に働き、且つ把持部４には係止部７の係止に逆おうとする方向の力が常に働いているので、本体部２には常に力が加えられ、本体部２に腰を与えることになる。よって、本発明のうちわ１を用いてあおいだ場合には、本体部２のたわみを抑制でき、充分な寿命が得られるという効果がある。
【００３９】
また本発明のうちわ１によれば、係止部７が略半円の円弧状となるので、係止部７を最適な形状とすることができ、強度が向上して充分な寿命が得られ、且つ容易に組み立てることができるという効果がある。係止部７が略半円よりも小さい円弧状である場合には把持部４を介挿することが難しく、また、係止部７が略半円よりも大きい円弧状である場合には、係止部７の強度が低下し、把持部４の力により破れやすくなるのである。
【００４０】
また本発明のうちわ１によれば、第２切込み６を入れることにより本体部側厚み部８が形成され、把持部４に第３切込み１３を入れることにより把持部側厚み部１４が形成されるので、本体部側厚み部８及び把持部側厚み部１４を容易に形成することができるという効果がある。また、第３切込み１３は連結部３を基準として第２切込み６と略対称であるので、把持部４が本体部２に設けられた係止部７に係止された状態では、第２切込み６と第３切込み１３が略一致する。よって、本体部側厚み部８および把持部側厚み部１４を折り曲げて把持部４を係止部７に係止した状態では、使用者がうちわ１を用いる際に上記第２切込み６と第３切込み１３に指をいれることができるようになるが、第２切込み６と第３切込み１３とは共に略円弧状であるので、指を痛めることがないという効果がある。さらに、共に連結部３へ向かって折り曲げられた本体部側厚み部８と把持部側厚み部１４とが、本体部２と把持部４との間で重なって、本体部２、連結部３、把持部４との間に形成される三角構造をさらに強化するので、強度が向上し、充分な寿命が得られる。
【００４１】
また本発明のうちわ１によれば、把持部４のうち円弧部１２の一部を前記係止部７に係止することによりうちわ１を組み立てることができるので、組み立てが容易であるという効果がある。さらに、係止部７と把持部４との間に働く力が一点に集中するため、本体部２がさらに安定するという効果がある。
【００４２】
また本発明のうちわ１によれば、把持部側厚み部１４および本体部側厚み部８は本体部２と把持部４との間に挟まれた状態で少なくとも１部において互いに接触し、且つ所定の角度を持って対向するものであることから、把持部側厚み部８と本体部側厚み部１４とがばねとして働き、把持部４が係止部７に逆らおうとする方向の力をより大きくするので、係止部７に働く力をより大きくすることができ、本体部２の腰をより強くし、うちわ１の強度を向上することができるという効果がある。
【００４３】
また本発明のうちわ１によれば、例えば合板に切刃及びけい線を組み込んだ抜き型を用いることにより１枚の段ボールから容易に成型でき、且つ、１枚の段ボールのうち廃棄される部分を少なくすることができるという効果がある。
【００４４】
以上、実施例に基づき本発明を説明したが、本発明は上記実施例に何ら限定される物ではなく、本発明の趣旨を逸脱しない範囲内で種々の改良変形が可能であることは容易に推察できるものである。
【００４５】
例えば、本実施例では、本体部２は略円盤状に構成されていたが、図３に変形例として示すうちわ２１のように、例えば本体部２２を矩形状とするなど、本体部が多角形状であっても良い。
【００４６】
また、本実施例では、把持部４が円弧部１２を有していたが、必ずしも有しなくとも良い。すなわち、図３に変形例として示すうちわ２１のように、把持部４のうち係止部７に係止される部分が直線上とされていても良い。
【００４７】
また、本実施例では、第１切込み５が略半円の円弧状とされていたが、図３に変形例として示すうちわ２１のように、例えばＶ字状の第１切込み２５とするなど、連結部２３の向きに凸の形状であれば良い。
【００４８】
また、本実施例では、うちわ１は１枚の段ボールから成型されていたが、例えば白板紙など厚い板状の紙、またはプラスチック製段ボールや合成樹脂製シートなどの腰のある板状の合成樹脂から成型されても良い。
