【発明の属する技術分野】
本発明は、キーホルダーに関し、特にキーホルダーからキー装着部が容易に脱落しない強固な構造を有するキーホルダーに関するものである。
【０００２】
【従来の技術】
図１０は、従来のキーホルダーの要部を示す切欠斜視図である。同図において、板状台座９の上端縁部に、複数の短冊状切欠部９ｂを形成することによって、複数の環状突出部９ａが形成され、環状突出部９ａ間にホルダー装着部１０が設けられている。ホルダー装着部１０は、棒状部材の先端部に頭部１１が形成され、かつ他端に環部１０ａが形成されており、環状突出部９ａ間に頭部１１が係合し、環部１０ａにキーが取り付けられるなす環１２が装着されている。ホルダー装着部１０が取り付けられた板状台座９は、折り畳み可能な蓋体７が一体となった保持板部６にリベット１３で固定されている。
【０００３】
【発明が解決しようとする課題】
従来のキーホルダーでは、板状台座９の環状突出部９ａ間に、ホルダー装着部１０の先端部の頭部１１が係合している。従って、頭部１１が摩耗するか、または、板状台座９に形成された短冊状切欠部９ｂに沿って、板状台座９が湾曲して短冊状切欠部９ｂの幅が拡大し、頭部１１が拡大した短冊状切欠部９ｂから擦り抜けてホルダー装着部１０が板状台座９から抜け落ち易くなる欠点があった。
【０００４】
また、従来のキーホルダーでは、キーやホルダー装着部１０が引っ張られると、ホルダー装着部１０の頭部１１と板状台座９の環状突出部９ａとに力が加わり易く、板状台座９が湾曲し易い構造となっている。このような要因から板状台座９からホルダー装着部１０が抜け落ち易い欠点があった。
【０００５】
本発明は、上述のような課題に鑑みなされたものであって、キーホルダーからキー装着部が容易に脱落しない強固な構造のキーホルダーを提供することを目的とするものである。
【０００６】
【課題を解決するための手段】
本発明は、上記課題を達成するためになされたものであり、請求項１の発明は、ハウジングに固定された板状台座と、
前記板状台座の上端縁部に固定した棒状部材と、
前記棒状部材が嵌通する嵌通穴と長穴とを設けた連結部材と、
前記連結部材の長穴に吊設した弾力性線材によるフック状のキー装着部と、
前記キー装着部を形成する該弾力性線材が挿通され、かつ該弾力性線材の端部を内側に屈曲させた端部に設けた折返部が挿入される閉管とを有し、
前記閉管に挿入された前記折返部を該閉管に係止して前記弾力性線材の弾力性により前記キー装着部の開放端を拘束し、かつ該キー装着部からキーを脱着する際には該閉管に係止された該折返部を該閉管から開放して該開放端の拘束を解除するようにしたことを特徴とするキーホルダーである。
【０００７】
請求項１の発明によれば、板状台座に固定された棒状部材には、キー装着部を吊設するための連結部材が貫通し、連結部材が棒状部材に回動自在に設けられてキー装着部が接続され、しかもキー装着部は、連結部材に設けた長穴に装着されており、キー装着部同士が絡み難い作用を有する。また、キー装着部が強く引っ張られたとしても棒状部材が設けられているので、板状台座が湾曲したり、反り返ったりすることがない作用を有する。
【０００８】
また、請求項２の発明は、前記キー装着部が、弾力性線材の一端に湾曲部を形成して、該湾曲部の端部を該弾力性線材と交差させ、前記嵌通穴に挿通される環部を形成し、前記弾力性線材の他端をフック状に屈曲させて弾性折曲部として、前記弾性折曲部の先端を内側に屈曲させ、かつその先端部を前記閉管に係止するための前記折返部を形成したことを特徴とする請求項１に記載のキーホルダーである。
【０００９】
請求項２の発明によれば、キー装着部の材料が弾力性線材で構成されており、環部が材質自体の弾性を利用して、交差部で湾曲部と弾力性線材とが強固に係合しており、かつフック状の弾性折曲部は、その解放端を閉管で閉じない場合、線材自体の弾性により解放され、弾性折曲部の解放端からキーを装着又は脱抜し得る状態となり、弾力性線材の折返部を閉管に挿入して係合させることによって、弾性折曲部の弾性を利用して、解放端を閉じることができる。
【００１０】
また、請求項３の発明は、前記キー装着部の解放端は、前記閉管の一端が前記折返部に係合し、該閉管の他端が前記湾曲部に係止されて閉じられ、かつキーの着脱時には、前記弾性折曲部を押圧して、該閉管に係合する該折返部を該閉管から挿脱して該開放端の拘束を解除することを特徴とする請求項２に記載のキーホルダーである。
【００１１】
請求項３の発明によれば、キー装着部は、弾力性線材で構成されており、弾性折曲部を指で押圧することにより、その先端部の折返部に係合していた閉管が外れる。閉管は、弾性折曲部に挿通したままで自由に移動し得る状態となるので、キー装着部からキーの挿脱ができる。
【００１２】
また、請求項４の発明は、前記板状台座が、その固定面よりその上端部が上方に屈曲し、その先端縁部に複数の環状突出部が形成され、該環状突出部に前記棒状部材を挟持して固定したことを特徴とする請求項１，２又は３に記載のキーホルダーである。

【００１５】
請求項５の発明によれば、化粧板を兼ねる保持板部をリベットによって板状台座と裏打板とで挟持して固定することにより、キー装着部が取り付けられる板状台座自体が保持板部から破損して抜け落ちるおそれがない。保持板部は、表化粧板と縫合されて蓋部と連なっている。
【００１６】
【発明の実施の形態】
以下、本発明に係るキーホルダーの実施の形態について、図面を参照して説明する。図１は、本発明の実施形態を示す一部切欠平面図である。同図において、板状台座１には、その上端縁部に複数の環状突出部１ａが形成され、環状突出部１ａに棒状部材２が挟持されて固定され、環状突出部１ａ間の隙間１ｂから棒状部材２が露呈し、これらの隙間１ｂに棒状部材２が嵌通する連結部材３が回動自在に設けられている。かつ連結部材３には、キーＫが装着されるキー装着部４が吊設されている。キー装着部４は、その解放端を閉管５で閉じることによって、キーＫが抜け落ちない構造となっている。板状台座１は、保持板部６にリベット８で固定されている。板状台座１に設けたキー装着部４は、皮革等の保持板部６と保持板部６の両側に連なる蓋部７とで覆うことができる。なお、本発明では、キー装着部４を覆う皮革等の保持板部６とその両側の蓋部７をハウジングと称する。無論、ハウジングは、実施形態に限定するものではない。
【００１７】
さらに、本実施形態のキーホルダーについて、図２乃至図５を参照して詳細に説明する。図２は、キーホルダーの要部を示し、棒状部材２は、板状台座１の一端縁に環状突出部１ａでかしめられて固定されている。棒状部材２には、図３に示したように、その端部に張り出し部２ａが形成され、環状突出部１ａで棒状部材２をかしめる際に、張り出し部２ａが環状突出部１ａの内壁部に噛み込まれて棒状部材２が強固に固着されている。
【００１８】
板状台座１は、上端部が保持板部６と接触した固定面より上方に屈曲して、断面への字状であり、板状台座１の長手方向の反りに対して強固な構造となっている。板状台座１の先端縁部には、複数の環状突出部１ａが形成されて、環状突出部１ａで棒状部材２が固定され、断面への字状構造と、棒状部材２とによって、一層強固な構造となっている。
【００１９】
連結部材３は、図４（ａ）に示したように、板状台座１の断面形状に沿うように、への字状の平板部材であり、その一端部に棒状部材２が嵌通する嵌通穴３ａが形成され、かつ他端部に長穴３ｂが形成されている。長穴３ｂは、この長穴３ｂに貫通する部材の自由度を高める作用を有する。
【００２０】
次に、キー装着部４については、図５（ａ），（ｂ）を参照して説明する。なお、図５（ａ）はその正面図であり、図５（ｂ）はその側面図である。同図において、キー装着部４は、その材質にステンレス等の弾力性線材が用いられる。例えば、弾力性線材の直径が１．２ｍｍのステンレス線材である。弾力性線材の一端は、環状に折り曲げられて、環部４ｃを形成し、その先端に湾曲部４ｂが形成され、さらに先端部４ａが正面に対して手前方向直角に突出している。なお、キー装着部４が、連結部材３に吊設される場合、湾曲部４ｂは、弾力性線材と交差し、弾力性線材の弾性によって押圧して連結部材３から容易に脱落しない構造となっている。一方、弾力性線材の他端には、フック状に屈曲した弾性折曲部４ｄが形成され、さらにその端部が内側に折り曲げられた屈曲部４ｅが形成され、その先端部に正面方向外側に折り返した折返部４ｆが形成されている。なお、キー装着部４は、連結部材３に吊設される前は、図５（ｂ）に示したように交差していないが、連結部材３に取り付けた後は、弾力性線材の弾力性を利用して、図２に示したように、湾曲部４ｂを弾力性線材に交差させて強固に固定されている。また、このキー装着部４は、図４（ｂ）に示した長穴状の嵌通穴が設けられた閉管５が弾力性線材に挿通されて、弾性折曲部４ｄの解放端を閉管５で拘束することによって閉じることができる。
【００２１】
なお、図６に示したように、リベット８の本体は、板状台座１と保持板部６とステレス板等の裏打板１ｃとを嵌通し、リベット８の本体の先端部をかしめることによって、保持板部６を板状台座１と裏打板１ｃとで強固に挟持している。保持板部６は、その上端縁と下端縁に縫代部６ａ，６ｂが設けられ、縫代部６ａ，６ｂが化粧板と縫合されている。皮革等の化粧板は、蓋部と連なっている。無論、板状台座１の固定は、この実施形態に限定するものではない。
【００２２】
続いて、図７，図８を参照して、閉管５による弾性折曲部４ｄの解放端の拘束について説明し、閉管５等を操作してキーＫをキー装着部４に装着する操作について説明する。先ず、図７の実線で示したように、閉管５は、弾性線材に挿通されて、かつ閉管５に挿通されている折返部４ｆが閉管５の一端部に係合し、閉管５の他端部が先端部４ａと湾曲部４ｂとに係止されている。フック状に屈曲した弾性折曲部４ｄの解放端は、このような組み合わせによって、閉じられている。
【００２３】
次に、図７の点線で示したように、弾性折曲部４ｄを指で押圧すると、弾性折曲部４ｄがバネ部材であるので、変形して閉管５と係合していた弾性折曲部４ｄの先端部の折返部４ｆが外れて、閉管５は、矢印Ｙ１に示したように、移動し得る状態となり、弾性折曲部４ｄの拘束が解除される。指を弾性折曲部４ｄから離すことによって、図８に示したように、閉管５に係合していた弾性折曲部４ｄの折返部４ｆが外れて解放される。キーＫをキー装着部４に装着する場合は、閉管５を弾性折曲部４ｄの解放端から外し、キーＫの穴Ｋａに折返部４ｆを挿通して、図７の矢印Ｙ２に示したように、再び閉管５に折返部４ｆを係合させて閉管５を戻すことによって、キー装着部４にキーＫを装着することができる。
【００２４】
続いて、図９を参照し、キー装着部４の弾力性について説明する。通常、閉管５は、キー装着部４の先端部４ａと折返部４ｆとで解放端が閉じられて固定されている。仮に、キー装着部４が矢印Ｙ３の方向に力が加わった場合、屈曲部４ｅが閉管５を引き下し、弾性折曲部４ｄが変形し、点線で示したように、閉管５が移動する。なお、弾性折曲部４ｄ′、折返部４ｆ′、屈曲部４ｅ′及び閉管５′は、矢印Ｙ３の方向に力が加わて変形した場合を示している。しかし、折返部４ｆは、閉管５に係合しており、折返部４ｆが閉管５から外れることはない。このように、キー装着部４に不必要な力が加わわったとしてもキー装着部４で吸収できる構造となっている。
【００２５】
【発明の効果】
以上説明したように、本発明によれば、連結部材が棒状部材に嵌通して、この連結部材にキー装着部が吊設された構造であり、従来のような板状台座の切欠を設けて環状突出部間に、キー装着部の頭部を架け渡す構造と比較して、板状台座が湾曲したり、反りが発生することが少なく、キー装着部が抜け落ちるおそれが極めて少ない利点がある。
【００２６】
また、本発明によれば、キーホルターに装着されたキーを強引に引っ張ったとしても、キー装着部自体が弾性を有する線材で形成され、かつキー装着部自体がばね構造となっているので、線材自体と構造的な弾力性によって、閉管が容易に外れることがなく、キー装着部からキーが抜け落ちるおそれがないし、しかも棒状部材に異常な力が加わわらないので、キー装着部が容易に脱落することがない利点がある。また、棒状部材に異常な力が加わったとしても板状台座を変形するまでには至らない利点がある。
【００２７】
また、本発明によれば、連結部材に長穴を設け、この長穴にキー装着部が吊設されているので、キー装着部が自在に回動する構造となっており、キー装着部同士が絡み合うおそれが少ない利点がある。
【００２８】
また、本発明によれば、板状台座の上端部が上方の折れ曲がった、断面への字状構造であるので、板状台座が構造的に強固である利点がある。
【００２９】
また、本発明によれば、板状台座が裏打板とで保持板部を強固に挟持しており、板状台座が保持板部から容易に抜け落ちることがない利点がある。

Next, as shown by the dotted line in FIG. 7, when the elastic bent portion 4 d is pressed with a finger, the elastic bent portion 4 d is a spring member, so that the elastic bent portion 4 d is deformed and engaged with the closed pipe 5. The folded portion 4f at the distal end of the portion 4d comes off, the closed tube 5 becomes movable as shown by the arrow Y1, and the restraint of the elastic bent portion 4d is released. By releasing the finger from the elastically bent portion 4d, as shown in FIG. 8, the bent portion 4f of the elastically bent portion 4d that has been engaged with the closed tube 5 is released and released. When the key K is mounted on the key mounting portion 4, the closed tube 5 is removed from the open end of the elastic bending portion 4d, and the bent portion 4f is inserted through the hole Ka of the key K, as shown by the arrow Y2 in FIG. Then, the key K can be mounted on the key mounting portion 4 by engaging the folded portion 4f with the closed tube 5 again and returning the closed tube 5.
[0024]
Next, the elasticity of the key mounting unit 4 will be described with reference to FIG. Normally, the open end of the closed tube 5 is closed and fixed by the distal end portion 4a of the key mounting portion 4 and the folded portion 4f. If a force is applied to the key mounting portion 4 in the direction of arrow Y3, the bent portion 4e pulls down the closed tube 5, the elastic bent portion 4d is deformed, and the closed tube 5 moves as shown by the dotted line. . Note that the elastic bent portion 4d ', the folded portion 4f', the bent portion 4e ', and the closed tube 5' show a case where a force is applied in the direction of arrow Y3 to deform. However, the folded portion 4f is engaged with the closed tube 5, and the folded portion 4f does not come off from the closed tube 5. As described above, even when an unnecessary force is applied to the key mounting portion 4, the key mounting portion 4 can absorb the force.

【The invention's effect】
As described above, according to the present invention, the connecting member is inserted into the rod-shaped member, and the key mounting portion is hung from the connecting member, and the notch of the conventional plate-shaped pedestal is provided. Compared to a structure in which the head of the key mounting portion is bridged between the annular projecting portions, there is an advantage that the plate-shaped pedestal is less likely to bend or warp, and the possibility that the key mounting portion falls off is extremely small.
[0026]
According to the present invention, even if the key mounted on the key halter is forcibly pulled, the key mounting portion itself is formed of an elastic wire, and the key mounting portion itself has a spring structure. Due to the wire itself and structural elasticity, the closed tube does not come off easily, the key does not fall off from the key mounting part, and the key mounting part falls off easily because no abnormal force is applied to the bar-shaped member There is no advantage to doing it. Further, there is an advantage that even if an abnormal force is applied to the rod-shaped member, the plate-shaped pedestal is not deformed.
[0027]
Further, according to the present invention, the connecting member is provided with a long hole, and the key mounting portion is suspended from the long hole, so that the key mounting portion is freely rotated. However, there is an advantage that there is little possibility of entanglement.
[0028]
Further, according to the present invention, since the upper end of the plate-shaped pedestal is bent upward and has a cross-shaped structure, there is an advantage that the plate-shaped pedestal is structurally strong.
[0029]
Further, according to the present invention, the plate-shaped pedestal firmly clamps the holding plate portion with the backing plate, and there is an advantage that the plate-shaped pedestal does not easily fall off the holding plate portion.
