Description

【０００１】
【発明の属する技術分野】
本発明は、例えば、自動車のインストルメントパネル側に開閉可能に取り付けられるグローブボックスの如き、収納体のサイドロック装置の改良に関するものである。
【０００２】
【従来の技術】
従来のこの種サイドロック装置は、具体的には図示しないが、グローブボックス本体の意匠面側にカム溝を形成した一対のカム部材を移動可能に設けて、該各カム部材にインストルメントパネルに形成されたロック孔を出入する一対のスライドピンを連結すると共に、各カム部材間に該左右の各スライドピンを常時ロック孔内に係入する方向へ付勢する圧縮コイルばねを装着する一方、操作ハンドル側に上記カム部材の各カム溝の溝縁に沿って移動する凸部を設ける構成となっている（例えば、特許文献１参照）。
【０００３】
そして、グローブボックス本体の閉塞状態にあっては、操作ハンドル側の凸部が対応するカム溝の内側に位置する関係で、左右のスライドピンの先端部がインストルメントパネル側のロック孔内に係入して、グローブボックス本体をその閉塞位置にロックすることとなるが、このロック状態を解除してグローブボックス本体を開放する場合には、操作ハンドルの揺動操作で、今度は、当該操作ハンドルの凸部をカム部材のカム溝の外側に移行させると、左右のカム部材が圧縮コイルばねの付勢ばね圧に抗して互いに接近する方向に移動して、スライドピンの先端部をロック孔から後退させるので、これにより、グローブボックス本体を開放方向へ移動させることが可能となる。

【発明が解決しようとする課題】
従って、従来のサイドロック装置にあっては、グローブボックス本体の両サイドにおいて、そのロック状態とロック解除状態が簡単に得られる利点はあるが、反面、サイドロック装置の本体部をグローブボックス本体の意匠面の表側から取り付けようとすると、特に、カム部材と操作ハンドルとを意匠面を傷つけないように取り付けなければならないので、慎重に作業をしなければならず、作業時間が自ずと長くなると共に、作業者の負担が大きくなる。又、カム部材が外側に突出していると、これを内側に押し込みながら組み付けなければならないので、いずれにしても、組付作業性が悪いという問題点があった。尚、このことは、サイドロック装置の取り付けをグローブボックス本体の意匠面の裏側から行なう場合でも、カム部材を内側に押し込みながら組み付けなければならないので、同様に、取り付けに手間がかかる。
【０００６】
【課題を解決するための手段】
本発明は、斯かる従来のサイドロック装置が抱える課題を有効に解決するために開発されたもので、請求項１記載の発明は、支持体に収納体を開閉可能に取り付けて、該収納体側に左右一対のスライドピンを移動可能に保持すると共に、該左右の各スライドピンを付勢ばね圧で支持体側に形成されたロック孔方向ヘ付勢して、操作ハンドルの揺動操作で、上記左右の各スライドピンの先端部を支持体側のロック孔から付勢ばね圧に抗して後退させるように構成したサイドロック装置において、上記操作ハンドル側に円筒部を形成して、該円筒部の内面に第１凸部と第２凸部を突設する一方、円筒部内に上記スライドピンを連結してその進退動を促すカム部材を摺動可能に挿入して、該カム部材の外周に上記第１凸部を摺接するカム溝を形成すると共に、カム部材が円筒部内に引き込まれた位置で、上記第２凸部を受け入れるロック溝を形成する構成を採用した。
【０００７】
請求項２記載の発明は、請求項１を前提として、ロック溝は、カム部材のカム溝の範囲内に位置して、カム溝よりも浅底に形成され、且つ、第１凸部よりも第２凸部の方がその高さ方向に対して短い構成を採用した。
【０００８】
請求項３記載の発明は、請求項２を前提として、ロック溝は、第１凸部の摺接するカム溝の範囲の内で、カム部材に対する付勢ばね圧が小さくなった時に、第１凸部が摺接する位置側に切り込まれている構成を採用した。
【０００９】
請求項４記載の発明は、請求項３を前提として、第１凸部をその巾方向に対して太く第２凸部をその巾方向に対して細くする一方、カム部材のカム溝は、略直角三角形状を呈して、上記巾方向に太い第１凸部が該カム溝の略直角三角形状の斜辺溝縁に沿って摺接状態をもって移動し、ロック溝の形成部位においては、カム溝の斜辺溝縁とロック溝の入口間は離間されて、上記巾方向に細い第２凸部のロック溝に受け入れられる通路を画成する構成を採用した。
【００１０】
請求項５記載の発明は、請求項４を前提として、第２凸部がロック溝に受け入れられている時には、第１凸部がロック溝の底面よりも深く形成されたカム溝の深底に存在する構成を採用した。
【００１１】
請求項６記載の発明は、請求項１を前提として、操作ハンドルの円筒部にスリットを設けて、該スリットと対向する円筒部の内面に第２凸部を突設し、スリットの内周開口縁側に第１凸部を突設する構成を採用した。
【００１２】
請求項７記載の発明は、請求項１を前提として、円筒部の内面の同一母線上に第１凸部と第２凸部とが存在する構成を採用した。
【００１３】
依って、請求項１記載の発明にあっては、操作ハンドルの円筒部内でカム部材を回転させて、該カム部材のロック溝内に第２凸部を導き入れれば、カム部材は操作ハンドルの円筒部内に引き込まれた状態に保持されるので、斯かる状態のまま、収納体の意匠面の表側からサイドロック装置の本体部を取り付ける場合にも、カム部材が邪魔になることがないので、その組付作業性が頗る向上すると共に、納品する場合でも、納品形態を可能な限り小さくできる。
【００１４】
請求項２記載の発明にあっては、ロック溝がカム部材のカム溝の範囲内に位置しているので、カム部材の長さ寸法を可能な限り短縮できる。請求項３記載の発明にあっては、やはり、カム部材を可能な限り短縮できると共に、操作ハンドルの円筒部も短縮できる。請求項４記載の発明にあっては、太い第１凸部は耐摩耗性が確保できると共に、細い第２凸部は離間するカム溝の溝縁とロック溝の入口間を通ってスムーズにロック溝内に受け入れられる。
【００１５】
請求項５記載の発明にあっては、第２凸部がロック溝に受け入れられている時には、第１凸部はカム溝の離れた深底に存在することとなるので、両凸部同士が干渉し合うことがない。請求項６記載の発明にあっては、操作ハンドルの円筒部に一つのスリットを設けるだけで、第１凸部と第２凸部を同時に形成できる。請求項７記載の発明にあっては、操作ハンドルの円筒部の強度低下や変形を小さく抑えて、カム部材の円滑な作動が期待できる。
【００１６】
【発明の実施の形態】
以下、本発明を図示する好適な実施の形態に基づいて詳述すれば、該実施の形態に係るサイドロック装置も、自動車のインストルメントパネルに開閉可能に取り付けられるグローブボックスを対象とするもので、そのボックス本体はインストルメントパネルの空所に回動可能に軸支されることを前提とする。
【００１７】
そして、本実施の形態に係るサイドロック装置は、図１に示す如く、上記グローブボックス本体の意匠面に画成される凹部内にあってグローブボックス本体の開閉を操作する操作ハンドル１と、該操作ハンドル１を揺動可能に支持して上記凹部内に延出する取付壁にネジ止めされる支持枠２と、左右一対のスライドピン３と、該左右の各スライドピン３の進退動を促す左右一対のカム部材４と、左右の各スライドピン３をインストルメントパネル側に形成されたロック孔方向に個々に付勢する２本の圧縮コイルばね５を備える構成となっている。
【００１８】
上記操作ハンドル１は、図２にも示す如く、その背面側にカム部材４と圧縮コイルばね５を左右で個々に収納する一対の円筒部６を一体に形成して、該各円筒部６の内面に後述するカム部材４のカム溝２０内を移動する一対の第１凸部７と、同ロック溝２１に受け入れられる１個の第２凸部８を突設するものであるが、この円柱状の各凸部７・８の突設に際しては、個々の円筒部６の長手方向にスリット９を設けて、該スリット９と対向する円筒部６の内面に第１凸部７に比し短くて細い第２凸部８を設け、スリット９の内周開口縁側に一方の第１凸部７を突設すると共に、該一方の第１凸部７と対向する円筒部６の内面に他方の第１凸部７を突設する構成となっている。尚、一対の第１凸部７は、上記した第２凸部８と比較すると、長くて太い形状が付与されている。
【００１９】
特に、本実施の形態にあって、操作ハンドル１に対して上記構成を採用したことは、円柱形状である一方の第１凸部７の半分を構成する半円柱形状をスリット９の周縁に設けることにより、横断面がスリット９の輪郭形状を呈する第１金型を円筒部６の内面に交差する方向に移動させ、横断面が円筒部６の内面の輪郭形状であり且つ端面に半円形状の凸部を持ち稜線部に半円形状の溝を持つ第２金型を円筒部６の軸方向に移動させて、第１金型の半円形状と第２金型の半円形状の凸部を係合すると、円筒部６の内面に第１金型と第２金型により円柱形状の溝が画成されて、この円柱形状の溝により一方の第１凸部７が成形されることとなるので、円筒部６と一方の第１凸部７を同時に成形することが可能となる。
【００２０】
又、他方の第１凸部７は円筒部６の内面の対向した位置にあるので、他方の第１凸部７の半分を構成する半円形状の溝を第１金型の端面に設け、第２金型の稜線部の円筒部６の中心軸線と対称となる位置に半円形状の溝を設けることにより、第１金型の半円形状と第２金型の半円形状の凸部が係合した時に、円筒部６の対向する位置に円形状の溝が２ヶ所できるので、他方の第１凸部７も同時に成形できる。更に、第２凸部８はスリット９の輪郭内部に存在するため、第１金型の端面に円柱形状の窪みを設けることにより、これも同時に成形できる。
【００２１】
従って、本実施の形態にあっては、既述したように配置された一対の第１凸部７と第２凸部８とは、操作ハンドル１を成形する際に、同時に成形できることとなる。しかも、他方の第１凸部７と第２凸部８は、円筒部６の内面で同一母線上に存在することとなるので、双方の円柱中心軸が平行となって、第１金型の移動方向とも平行となり、一方の第１凸部７の円柱中心軸は他方の凸部７の円柱中心軸が重なるため、一対の第１凸部７と第２凸部８の円柱中心軸は全て円筒部６の中心軸と直交することとなる結果、第１凸部７と第２凸部８の円柱外周は後述するカム部材４のカム溝２０と平行となるので、少なくとも、第１凸部７はカム溝２０と円滑に摺動できることとなる。
【００２２】
支持枠２は、その背面側に複数のネジ孔１０を形成すると共に、両側縁に上記円筒部６方向に折曲する折曲壁１１を延設して、該各折曲壁１１の中央部に各カム部材４の先端側の出没を許容する開口１２を形成する構成となっている。
【００２３】
左右一対のスライドピン３は、勝手違いに成形されるものであるが、基本的には、図３にも示す如く、その後端部側に後述するカム部材４の連結片１８を嵌合する貫通孔１３を形成して、該貫通孔１３を画成する上下の壁部外面に後述するカム部材４の係止孔１７に係止する突起１４を個々に形成する構成となっている。又、操作ハンドル１がグローブボックス本体の中央に配置される場合には、各スライドピン３の形状が左右同一となるが、操作ハンドル１が左右どちらか寄りに配置される場合には、各スライドピン３の形状が左右同一とならないので、スライドピン３を組み付ける際に、左右のスライドピン３の誤組付防止のための凹溝２３が後端部側面に形成してある。更に、スライドピン３の先端部側に傾斜面を設けて、グローブボックス本体をインストルメントパネル側に回動させる時には、スライドピン３がインストルメントパネル側に設けられているロック孔に係入し易くしてあるので、スライドピン３自身にも組付方向があり、上記した凹溝２３は組付方向の誤認防止にも有効に作用することとなる。
【００２４】
カム部材４は、左右対称に成形されるものであるが、基本的には、図４にも示す如く、そのフランジ部１６を境とする先端側を角筒状に形成し、後端側を円筒状に形成して、前者の角筒状先端部４ａに対しては、その上下側面に上記スライドピン３の突起１４を係止する係止孔１７を形成すると共に、他で対向する一側面に上記した貫通孔１３と嵌合する連結片１８を形成し、且つ、他側面の内側に誤組み付け防止用のリブ壁１９を形成する構成となっている。
【００２５】
又、後者の円筒状後端部４ｂに対しては、その外周に略直角三角形状を呈するカム溝２０とカム部材４の軸線に平行な誘導溝２０ａとを形成し、該カム溝２０と誘導溝２０ａとは壁を隔てて同じ深さに形成されるが、フランジ部１６の近傍にカム溝２０と誘導溝２０ａとを繋げる通路が画成されている。上記誘導溝２０ａは円筒状後端部４ｂの端面まで達しており、カム部材４を軸線方向に移動させると、上記した第１凸部７が当該端面側から誘導溝２０ａに入り込み、上記通路を通って略直角三角形状のカム溝２０内に導入される。そして、サイドロック装置が組み上がった後、操作ハンドル１を把持して引き上げると、第１凸部７がカム溝２０を形成する略直角三角形状の斜辺溝縁に沿って摺接状態をもって移動する構成となっている。尚、円筒状後端部４ｂには、軸線を中心に１８０°回転させた位置にも、上記と同様なカム溝２０と誘導溝２０ａが形成されているため、一対の第１凸部７が対応するカム溝２０に導き入れられることとなる。
【００２６】
これに加えて、上記一方のカム溝２０の長手方向の範囲内で、カム部材４に対する圧縮コイルばね５の付勢ばね圧が小さくなった時（伸長した時）に、第１凸部７がカム溝２０の円筒状後端部４ｂの端面側で摺接する位置に第２凸部８を受け入れるロック溝２１を切り込ませて形成する構成となっている。又、このロック溝２１が形成されるカム溝２０の略直角三角形状を形成する斜辺溝縁に段差部２２を設けることにより、カム溝２０とロック溝２１の分岐部が当該段差部２２上に形成されることとなるので、略直角三角形状のカム溝２０の斜辺溝縁に接触する第１凸部７は、分岐部から離れた状態で摺動する。従って、第１凸部７がカム溝２０に沿って摺動する際には、分岐部を接触して通過することがないので、操作ハンドル１を操作する際には、何かが引っ掛かったような引掛感が発生する要因はなく、操作者に不快な違和感を与えることがない。
【００２７】
尚、カム溝２０と誘導溝２０ａの底面はロック溝２１のそれと比べると深底となっており、且つ、ロック溝２１の形成部位においては、カム溝２０の斜辺溝縁とロック溝２１の入口間は離間されて、第２凸部８のロック溝２１に受け入れられる通路を画成する構成となっている。又、ロック溝２１は、カム部材４の円筒状後端部４ｂの端面近くで、略直角三角形状のカム溝２０の斜辺の外側に形成された全体が略矩形状を呈する窪みとして構成され、当該略矩形状のロック溝２１は、カム溝２０の斜辺側で且つカム部材４の中央寄りの角でカム溝２０と繋がっている。更に、ロック溝２１は、カム溝２０の斜辺側で且つカム部材４の端面側の角に、カム部材４を操作ハンドル１の円筒部６内に引き込んだ状態に保持するため、第２凸部８を係合する隅肉部２１ａを有し、該隅肉部２１ａの一辺を構成し且つカム部材４の軸線と平行な壁は、カム溝２０の斜辺と間隔をおいて形成されるので、第１凸部７がカム溝２０に沿って摺動する際には、何かが引っ掛かったような引掛感が発生することはない。又、この隅肉部２１ａは、カム部材４が回転しても、係合する第２凸部８がロック溝２１から脱落しないように設けられているものであるから、その目的を満たせば、上記した隅肉部２１ａの壁はカム部材４の軸線と平行である必要はなく、ある程度傾斜していても構わないし、且つ、壁でなく突起であっても構わない。
【００２８】
これに加えて、本実施の形態に係る操作ハンドル１にはシリンダ錠を配置していないが、一対のカム部材４の間にシリンダ錠を配置する操作ハンドルも存在する。この場合、操作ハンドルに対して、一対のカム部材４とシリンダ錠が同一軸線上に配置されることとなるが、ロック溝２１をカム部材４の円筒状後端部４ｂの端面近くで、カム溝２０の斜辺の外側に位置させることにより、操作ハンドル１に操作者が把持するために必要十分な巾を持たせて、操作ハンドル１を違和感なく引き上げることができる角度を確保することが可能となる。その上、本実施の形態にあっては、シリンダ錠を配置しない操作ハンドルとシリンダ錠を配置する操作ハンドルの構成部品を共用化してコストダウンを図っているので、ロック溝２１をカム部材４の円筒状後端部４ｂの端面近くでカム溝２０の斜辺と一辺で形成される角近くの外側に配置することが有効である。
【００２９】
依って、斯かる構成のサイドロック装置を組み付ける場合には、まず、操作ハンドル１側の各円筒部６内に左右の圧縮コイルばね５とカム部材４とを個々に挿入することとなるが、この場合には、カム部材４の円筒状後端部４ｂの外周に形成されている一対のカム溝２０の誘導溝２０ａ内に対応する第１凸部７を臨ませながら、カム部材４の円筒状後端部４ｂを円筒部６内に押し込んで所定方向に回転して、当該第１凸部７をカム溝２０内に係入させれば、左右の各カム部材４は、図５に示す如く、各圧縮コイルばね５のばね圧で、その角筒状先端部４ａを外部に突出させた状態に付勢されることとなる。
【００３０】
次いで、今度は、この状態にある操作ハンドル１に支持枠２を組み付けることとなるが、この場合には、各カム部材４を回転させながら円筒部６内に押し込んで、カム溝２０の斜辺溝縁の内側に摺接している第１凸部７をカム溝２０内で外側方向へ移行させれば、図６に示す如く、ロック溝２１に第２凸部８が導き入れられて、カム部材４全体が円筒部６内に引き込まれることとなるので、後は、斯かる状態を利用して、支持枠２を操作ハンドル１の背面側に被嵌すれば、これにより、支持枠２が操作ハンドル１側に組み付けられることとなる。尚、この場合には、離間して、第１凸部７がカム溝２０の深底に存在し、第２凸部８がロック溝２１の浅底に存在することとなるので、両凸部７・８同士が干渉し合うことはない。
【００３１】
従って、後は、斯かる状態のまま、グローブボックス本体の凹部内に延出する取付壁に支持枠２をネジ止めすれば、当該凹部側に操作ハンドル１が揺動可能に支持されることとなる訳であるが、この場合には、左右のカム部材４の角筒状先端部４ａが外部に突出していないので、組付作業が頗る容易となると共に、納品する場合にも、カム部材４を引き込んだ状態で納品できるので、納品形態も可能な限り小さくできる。
【００３２】
しかも、カム部材４を円筒部６内に引き込んだ状態では、図７に示す如く、操作ハンドル１が開状態となって、持ち易くなるので、この点からも、組付作業が容易となり、支持枠２を取付壁にネジ止めした後は、開状態にある操作ハンドル１を閉じれば、カム部材４の円筒部６内に対する引き込み状態が解除されて、カム部材４の角筒状先端部４ａが支持枠２の開口１２から外方に突出することとなるので、後は、各カム部材４の角筒状先端部４ａに左右の各スライドピン３の後端部を内嵌すれば、これにより、サイドロック装置が組み立てられることとなる。この時には、誤組み付け防止用のリブ壁１９がスライドピン３の貫通孔１３を画成する凹溝２３に嵌合することにより挿入できるようになり、仮に、挿入向きや左右のスライドピン３を誤って挿入しても、凹溝２３を有しない壁部側面が上記リブ壁１９に当たって嵌入することができないので、左右のスライドピン３が誤って組み付けられることもない。
【００３３】
尚、斯かる状態にあっては、スライドピン３の後端部をカム部材４の角筒状先端部４ａに内嵌すると、スライドピン３に設けられている突起１４が係止孔１７に係止するので、その抜け外れが有効に防止されると同時に、カム部材４側の連結片１８がスライドビン３の貫通孔１３内に圧入され、連結片１８の先端角部が貫通孔１３の内面を押し広げるので、スライドピン３のガタツキをも有効に防止できる。
【００３４】
従って、これにより、実際の使用に供せられることとなる訳であるが、操作ハンドル１を揺動操作させない状態にあっては、図８に示す如く、左右一対のスライドピン３が圧縮コイルばね５の付勢ばね圧で伸長して、グローブボックス本体（図示せず）の側面に形成されている通孔（図示せず）からインストルメントパネルＰのロック孔Ｈに係入しているので、これにより、グローブボックス本体が閉塞状態にロックされることとなる。
【００３５】
又、斯かるロック状態を解除する場合には、操作ハンドル１を把持して引き上げると、円筒部６内の第１凸部７が対応するカム溝２０の斜辺溝縁に沿って移動して、カム部材４を円筒部６内に引き込ませるので、図９に示す如く、各スライドピン３の先端部がインストルメントパネルＰのロック孔Ｈから後退して、グローブボックス本体が開放方向へ回動することが許容されることとなる。
【００３６】
【発明の効果】
以上の如く、本発明は、上記構成の採用により、操作ハンドルの円筒部内でカム部材を回転させて、該カム部材のロック溝内に第２凸部を導き入れれば、カム部材は操作ハンドルの円筒部内に引き込まれた状態に保持されるので、斯かる状態のまま、収納体の意匠面の表側からサイドロック装置の本体部を取り付ける場合にも、カム部材が邪魔になることがないので、その組付作業性が頗る向上すると共に、納品する場合でも、納品形態を可能な限り小さくできる。

BACKGROUND OF THE INVENTION
The present invention relates to an improvement in a side lock device of a storage body, such as a glove box that can be opened and closed on the instrument panel side of an automobile.
[0002]
[Prior art]
Although this type of conventional side lock device is not specifically shown, a pair of cam members having cam grooves formed on the design surface side of the glove box body are provided movably, and the instrument panel is attached to each cam member. While connecting a pair of slide pins that enter and exit the formed lock hole, and mounting a compression coil spring that urges the left and right slide pins in the direction to always engage the lock hole between the cam members, A convex portion that moves along the edge of each cam groove of the cam member is provided on the operation handle side (see, for example, Patent Document 1).
[0003]
In the closed state of the glove box body, the tip of the left and right slide pins is engaged in the lock hole on the instrument panel side because the convex portion on the operation handle side is positioned inside the corresponding cam groove. The glove box body is locked in its closed position, but when releasing the locked state and opening the glove box body, the operation handle is swung. When the convex portion of the cam member is shifted to the outside of the cam groove of the cam member, the left and right cam members move toward each other against the biasing spring pressure of the compression coil spring, and the tip of the slide pin is locked to the lock hole. Therefore, the glove box body can be moved in the opening direction.
[0004]

[Problems to be solved by the invention]
Therefore, in the conventional side lock device, there is an advantage that the locked state and the unlocked state can be easily obtained on both sides of the glove box body. When trying to attach from the front side of the design surface, especially the cam member and the operation handle must be attached so as not to damage the design surface, so the work must be done carefully, the work time will naturally become longer, The burden on the worker increases. Further, if the cam member protrudes outward, it must be assembled while being pushed inward, and in any case, there has been a problem that the assembly workability is poor. In addition, even when attaching a side lock apparatus from the back side of the design surface of a glove box main body, since it has to assemble | move while pushing a cam member inside, it takes time and effort similarly.
[0006]
[Means for Solving the Problems]
The present invention was developed in order to effectively solve the problems of such a conventional side lock device, and the invention according to claim 1 attaches a storage body to a support body so that the storage body can be opened and closed. A pair of left and right slide pins are movably held at the same time, and each of the left and right slide pins is biased toward the lock hole formed on the support side by a biasing spring pressure, and the operation handle is swung to In the side lock device configured to retract the front end of each of the left and right slide pins from the lock hole on the support body against the biasing spring pressure, a cylindrical portion is formed on the operation handle side, While projecting the first and second convex portions on the inner surface, a cam member that slidably inserts the slide pin into the cylindrical portion and urges its forward and backward movement is inserted into the outer periphery of the cam member. Form a cam groove to slidably contact the first convex part Together, at a position where the cam member is pulled into the cylindrical portion, and employs a configuration that forms a locking groove for receiving the second projection.
[0007]
According to a second aspect of the present invention, on the premise of the first aspect, the lock groove is located within the cam groove of the cam member, is formed at a shallower depth than the cam groove, and more than the first convex portion. A configuration in which the second convex portion is shorter in the height direction is adopted.
[0008]
According to a third aspect of the present invention, on the premise of the second aspect, the lock groove has a first convexity when the biasing spring pressure against the cam member is reduced within the range of the cam groove in sliding contact with the first convex part. A configuration is adopted in which the part is cut into the side where the part comes into sliding contact.
[0009]

DETAILED DESCRIPTION OF THE INVENTION
Hereinafter, if the present invention is described in detail based on a preferred embodiment illustrated, the side lock device according to the embodiment is also intended for a glove box attached to an instrument panel of an automobile so as to be opened and closed. The box body is presupposed to be pivotally supported in the empty space of the instrument panel.
[0017]
And, as shown in FIG. 1, the side lock device according to the present embodiment is in a recess defined in the design surface of the glove box body, and an operation handle 1 for operating the opening and closing of the glove box body, A support frame 2 that supports the operation handle 1 in a swingable manner and is screwed to a mounting wall that extends into the recess, a pair of left and right slide pins 3, and a forward and backward movement of the left and right slide pins 3 are urged. A pair of left and right cam members 4 and two compression coil springs 5 for individually urging the left and right slide pins 3 in the direction of a lock hole formed on the instrument panel side are provided.
[0018]
As shown in FIG. 2, the operation handle 1 is integrally formed with a pair of cylindrical portions 6 for individually accommodating the cam member 4 and the compression coil spring 5 on the left and right sides on the back side thereof. A pair of first protrusions 7 that move in a cam groove 20 of the cam member 4 to be described later and one second protrusion 8 that is received in the lock groove 21 protrude from the inner surface. When projecting the columnar convex portions 7 and 8, slits 9 are provided in the longitudinal direction of the individual cylindrical portions 6, and the inner surfaces of the cylindrical portions 6 facing the slits 9 are shorter than the first convex portions 7. The thin second convex portion 8 is provided, and one first convex portion 7 is projected on the inner peripheral opening edge side of the slit 9, and the other inner surface of the cylindrical portion 6 facing the one first convex portion 7 is provided on the other side. The first convex portion 7 is configured to project. Note that the pair of first protrusions 7 has a longer and thicker shape than the second protrusions 8 described above.
[0019]
In particular, in the present embodiment, the above-described configuration is adopted for the operation handle 1 because a semi-cylindrical shape that constitutes a half of the first convex portion 7 having a cylindrical shape is provided on the periphery of the slit 9. Accordingly, the first mold having a cross section of the contour shape of the slit 9 is moved in a direction intersecting the inner surface of the cylindrical portion 6, and the cross section is the contour shape of the inner surface of the cylindrical portion 6 and is semicircular at the end surface The second mold having a convex portion and a semicircular groove in the ridge line portion is moved in the axial direction of the cylindrical portion 6 so that the semicircular shape of the first die and the semicircular shape of the second die When the portions are engaged, a cylindrical groove is defined on the inner surface of the cylindrical portion 6 by the first die and the second die, and one first convex portion 7 is formed by the cylindrical groove. Thus, the cylindrical portion 6 and the first convex portion 7 can be formed at the same time.
[0020]
Further, since the other first convex portion 7 is located at an opposite position on the inner surface of the cylindrical portion 6, a semicircular groove constituting half of the other first convex portion 7 is provided on the end surface of the first mold, By providing a semicircular groove at a position symmetrical to the central axis of the cylindrical portion 6 of the ridge line portion of the second mold, the semicircular shape of the first mold and the semicircular convex portion of the second mold Since the two circular grooves can be formed at opposite positions of the cylindrical portion 6 when the two are engaged, the other first convex portion 7 can be formed at the same time. Furthermore, since the 2nd convex part 8 exists in the outline inside of the slit 9, this can also be shape | molded simultaneously by providing a cylindrical hollow in the end surface of a 1st metal mold | die.
[0021]
Therefore, in the present embodiment, the pair of first convex portions 7 and the second convex portions 8 arranged as described above can be simultaneously formed when the operation handle 1 is formed. In addition, since the other first convex portion 7 and the second convex portion 8 are present on the same generatrix on the inner surface of the cylindrical portion 6, both the central axes of the cylinders are parallel to each other, Since the cylindrical central axis of one first convex part 7 overlaps the cylindrical central axis of the other convex part 7, the cylindrical central axes of the pair of first convex part 7 and second convex part 8 are all parallel. As a result of being orthogonal to the central axis of the cylindrical portion 6, the outer circumferences of the first convex portion 7 and the second convex portion 8 are parallel to a cam groove 20 of the cam member 4 to be described later. 7 can slide smoothly with the cam groove 20.
[0022]
The support frame 2 is formed with a plurality of screw holes 10 on the back side thereof, and a bent wall 11 that is bent in the direction of the cylindrical portion 6 is extended on both side edges, and the center portion of each bent wall 11 is extended. In addition, an opening 12 that allows the cam member 4 to protrude and project on the tip side is formed.
[0023]
The pair of left and right slide pins 3 are formed arbitrarily, but basically, as shown in FIG. 3, as shown in FIG. A hole 13 is formed, and projections 14 that are locked to locking holes 17 of the cam member 4 to be described later are individually formed on the outer surfaces of the upper and lower wall portions that define the through-hole 13. Further, when the operation handle 1 is arranged at the center of the glove box body, the shape of each slide pin 3 is the same on the left and right, but when the operation handle 1 is arranged on either the left or right side, each slide Since the shape of the pin 3 does not become the same on the left and right, when the slide pin 3 is assembled, a concave groove 23 for preventing erroneous assembly of the left and right slide pins 3 is formed on the side surface of the rear end. Furthermore, when the inclined surface is provided on the distal end side of the slide pin 3 and the glove box body is rotated toward the instrument panel side, the slide pin 3 is easily engaged in the lock hole provided on the instrument panel side. Therefore, the slide pin 3 itself also has an assembly direction, and the above-described concave groove 23 effectively acts to prevent misidentification of the assembly direction.
[0024]
The cam member 4 is formed symmetrically. Basically, as shown in FIG. 4, the front end side with the flange portion 16 as a boundary is formed in a rectangular tube shape, and the rear end side is formed. A cylindrical hole is formed on the upper and lower side surfaces of the former rectangular tube tip 4a, and a locking hole 17 for locking the projection 14 of the slide pin 3 is formed on the other side surface. The connecting piece 18 that fits into the through hole 13 is formed, and the rib wall 19 for preventing misassembly is formed inside the other side surface.
[0025]
Further, for the latter cylindrical rear end portion 4b, a cam groove 20 having a substantially right triangle shape is formed on the outer periphery thereof, and a guide groove 20a parallel to the axis of the cam member 4 is formed. The groove 20a is formed at the same depth across the wall, but a passage connecting the cam groove 20 and the guide groove 20a is defined in the vicinity of the flange portion 16. The guide groove 20a reaches the end surface of the cylindrical rear end portion 4b. When the cam member 4 is moved in the axial direction, the first convex portion 7 enters the guide groove 20a from the end surface side, and passes through the passage. It is introduced into the cam groove 20 having a substantially right triangle shape. Then, after the side lock device is assembled, when the operation handle 1 is grasped and pulled up, the first convex portion 7 moves in a sliding contact state along the oblique side groove edge of the substantially right triangle shape forming the cam groove 20. It has a configuration. In addition, since the cam groove 20 and the guide groove 20a similar to the above are formed in the cylindrical rear end portion 4b at a position rotated by 180 ° about the axis, the pair of first convex portions 7 are formed. It will be introduced into the corresponding cam groove 20.
[0026]
In addition to this, when the biasing spring pressure of the compression coil spring 5 with respect to the cam member 4 becomes smaller (extends) within the longitudinal range of the one cam groove 20, the first convex portion 7 is The lock groove 21 that receives the second convex portion 8 is cut and formed at a position in sliding contact with the end face side of the cylindrical rear end portion 4 b of the cam groove 20. Further, by providing a step portion 22 at the edge of the oblique side that forms a substantially right triangle shape of the cam groove 20 in which the lock groove 21 is formed, the branch portion of the cam groove 20 and the lock groove 21 is placed on the step portion 22. As a result, the first convex portion 7 that contacts the edge of the oblique side of the cam groove 20 having a substantially right triangle shape slides away from the branch portion. Therefore, when the first convex portion 7 slides along the cam groove 20, it does not pass through the branch portion, so that something seems to be caught when the operation handle 1 is operated. There is no factor that causes an uncomfortable feeling of touch and does not give an uncomfortable feeling to the operator.
[0027]
The bottom surfaces of the cam groove 20 and the guide groove 20 a are deeper than those of the lock groove 21, and the oblique groove edge of the cam groove 20 and the entrance of the lock groove 21 are formed at the portion where the lock groove 21 is formed. The gap is spaced apart to define a passage that is received in the lock groove 21 of the second convex portion 8. Further, the lock groove 21 is configured as a hollow having a substantially rectangular shape as a whole formed near the end surface of the cylindrical rear end portion 4b of the cam member 4 and outside the oblique side of the cam groove 20 having a substantially right triangle shape. The substantially rectangular lock groove 21 is connected to the cam groove 20 at the corner on the oblique side of the cam groove 20 and closer to the center of the cam member 4. Further, the lock groove 21 holds the cam member 4 in a state where the cam member 4 is drawn into the cylindrical portion 6 of the operation handle 1 at the oblique side of the cam groove 20 and the end surface side of the cam member 4. 8, the wall that constitutes one side of the fillet portion 21 a and is parallel to the axis of the cam member 4 is formed at a distance from the oblique side of the cam groove 20. When the first convex portion 7 slides along the cam groove 20, there is no such a feeling that something is caught. The fillet portion 21a is provided so that the engaging second convex portion 8 does not fall off the lock groove 21 even when the cam member 4 rotates. The wall of the fillet portion 21a does not need to be parallel to the axis of the cam member 4, may be inclined to some extent, and may be a protrusion instead of a wall.
[0028]
In addition to this, a cylinder lock is not arranged in the operation handle 1 according to the present embodiment, but there is also an operation handle that arranges the cylinder lock between the pair of cam members 4. In this case, the pair of cam members 4 and the cylinder lock are disposed on the same axis with respect to the operation handle. However, the lock groove 21 is located near the end surface of the cylindrical rear end portion 4b of the cam member 4 and the cam. By positioning it outside the oblique side of the groove 20, it is possible to secure an angle at which the operation handle 1 can be lifted without a sense of incongruity by providing the operation handle 1 with a necessary and sufficient width for the operator to grip. Become. In addition, in the present embodiment, the cost is reduced by sharing the components of the operation handle where the cylinder lock is not arranged and the operation handle where the cylinder lock is arranged. It is effective to arrange it near the end surface of the cylindrical rear end portion 4b and outside the corner formed by the oblique side and one side of the cam groove 20.
[0029]
Therefore, when assembling the side lock device having such a configuration, first, the left and right compression coil springs 5 and the cam members 4 are individually inserted into the respective cylindrical portions 6 on the operation handle 1 side. In this case, the cylinder of the cam member 4 faces the first convex portion 7 in the guide groove 20a of the pair of cam grooves 20 formed on the outer periphery of the cylindrical rear end portion 4b of the cam member 4. When the first rear portion 4b is pushed into the cylindrical portion 6 and rotated in a predetermined direction to engage the first convex portion 7 into the cam groove 20, the left and right cam members 4 are shown in FIG. As described above, the spring pressure of each compression coil spring 5 biases the square cylindrical tip 4a to a state of protruding outward.
[0030]
Next, the support frame 2 is assembled to the operation handle 1 in this state. In this case, each cam member 4 is pushed into the cylindrical portion 6 while rotating, and the oblique side groove of the cam groove 20 is inserted. If the first convex portion 7 that is in sliding contact with the inner side of the edge is moved outward in the cam groove 20, the second convex portion 8 is introduced into the lock groove 21 as shown in FIG. Since the entire frame 4 is drawn into the cylindrical portion 6, the support frame 2 can be operated by applying the support frame 2 to the back side of the operation handle 1 using such a state. It will be assembled to the handle 1 side. In this case, since the first convex portion 7 is present at the deep bottom of the cam groove 20 and the second convex portion 8 is present at the shallow bottom of the lock groove 21, the two convex portions are separated. 7.8 does not interfere with each other.
[0031]
Therefore, after that, if the support frame 2 is screwed to the mounting wall extending into the recess of the glove box body in such a state, the operation handle 1 is swingably supported on the recess side. In this case, however, since the square cylindrical tip portions 4a of the left and right cam members 4 do not protrude to the outside, the assembling work is facilitated and the cam members 4 can be delivered. Can be delivered in a retracted state, so the delivery form can be made as small as possible.
[0032]
In addition, when the cam member 4 is pulled into the cylindrical portion 6, as shown in FIG. 7, the operation handle 1 is opened and easy to hold. From this point, the assembling work is facilitated and supported. After the frame 2 is screwed to the mounting wall, if the operating handle 1 in the open state is closed, the retracted state of the cam member 4 into the cylindrical portion 6 is released, and the square cylindrical tip portion 4a of the cam member 4 is released. Since it protrudes outward from the opening 12 of the support frame 2, if the rear end portions of the left and right slide pins 3 are fitted in the square cylindrical tip portions 4 a of the cam members 4, The side lock device will be assembled. At this time, the rib wall 19 for preventing wrong assembly can be inserted into the concave groove 23 that defines the through hole 13 of the slide pin 3, so that the insertion direction and the right and left slide pins 3 can be mistakenly inserted. Even if inserted, the side surface of the wall portion that does not have the concave groove 23 cannot be fitted into the rib wall 19, so that the left and right slide pins 3 are not erroneously assembled.
[0033]
In such a state, when the rear end portion of the slide pin 3 is fitted into the square cylindrical tip portion 4 a of the cam member 4, the protrusion 14 provided on the slide pin 3 is engaged with the locking hole 17. Therefore, the connecting piece 18 on the cam member 4 side is press-fitted into the through hole 13 of the slide bin 3, and the tip corner of the connecting piece 18 is the inner surface of the through hole 13. Can be effectively prevented from rattling of the slide pin 3.
[0034]
Therefore, although this is used for actual use, as shown in FIG. 8, when the operating handle 1 is not swung, the pair of left and right slide pins 3 are compressed coil springs. Since it is extended by the biasing spring pressure of 5 and is engaged with the lock hole H of the instrument panel P from the through hole (not shown) formed in the side surface of the glove box body (not shown), As a result, the glove box body is locked in the closed state.
[0035]
In order to release such a locked state, when the operation handle 1 is grasped and pulled up, the first convex portion 7 in the cylindrical portion 6 moves along the hypotenuse groove edge of the corresponding cam groove 20, Since the cam member 4 is drawn into the cylindrical portion 6, as shown in FIG. 9, the distal end portion of each slide pin 3 retreats from the lock hole H of the instrument panel P, and the glove box body rotates in the opening direction. It will be allowed.
[0036]
【The invention's effect】
As described above, according to the present invention, when the cam member is rotated in the cylindrical portion of the operation handle and the second convex portion is introduced into the lock groove of the cam member by adopting the above-described configuration, Since it is held in the state of being drawn into the cylindrical portion, even when attaching the main body portion of the side lock device from the front side of the design surface of the storage body in such a state, the cam member does not get in the way, The assembly workability is greatly improved, and the delivery form can be made as small as possible even when delivered.
