Description

【0001】
【発明が属する技術分野】
本発明は自動販売機の扉等に使用される錠装置に関するものである。
【0002】
【従来の技術】
一般の扉等に使用されている錠装置では、操作者が鍵をロータの鍵孔に挿入して所定方向に回すと、内蔵の連動機構を介してロック部材が施錠位置に駆動されるものであるが、ロック部材が係合する筐体や建物側の受金部材は、防犯対策上から操作者によく見えない位置に設けられているため、ロック部材が受金部材に正規位置において完全に係合しているかどうかを操作者が目視確認することは困難である。
【0003】
通常は、鍵が正規の施錠角度である90度まで回転したかどうかを、鍵の回転終端における位置姿勢によって判別するのであるが、経年使用によって鍵や鍵孔の摩り減りが進み、鍵がぐらつくようになった段階では、この判別の正確性は保証の限りではない。
そのため、ロック部材が受金部材と完全に係合していない所謂半掛かりの状態であるのにもかかわらず、施錠成立と誤信して操作者が立ち去ったときには、後で振動衝撃によってロック部材と受金部材の半掛かり状態が偶発的に解除され、扉等が無意図的に開いてしまう危険性がある。
【0004】
【発明が解決しようとする課題】
したがって本発明の目的は、施錠が操作者の手動操作によって操作者の目視下において実感的に完全になされることになり、施錠の確実性と信頼性に優れている受金ピン抜差し型の錠装置を提供することである。
【0005】
【課題を解決するための手段】
以下、添付図面中の参照符号を用いて説明すると、請求項1の発明の錠装置は、ハウジング1の端面に開口する第1空洞2をハウジング1に形成し、第1空洞2に錠ケース3を出没可能に収納し、錠ケース3に錠前ユニット4を収納し、ハウジング1に掛金体5が挿入される受溝6を形成し、受溝6内に出入りして掛金体5に係合する受金ピン7をハウジング1の受孔8に嵌挿し、受金ピン7を錠ケース3に相対回転可能に連結し、錠前ユニット4のロータ9に受金ピン7を連結し、第1空洞2に連続する第2空洞10にカム円盤11を収容し、カム円盤11を受金ピン7に連結し、ハウジング1のガイド孔12に嵌挿したラッチボルト13をバネ14によってカム円盤11に向かって移動付勢し、カム円盤11の下面側周縁部の一部を切り欠いて錠止段部15を形成し、錠止段部15の一対の内壁面の奥部に駆動カム面33を形成し、ラッチボルト13の先端部分13aの側面部に一対の従動カム面34を形成し、ラッチボルト13の先端部分13aの下面部にカム円盤11の周縁肩部に押されるラッチ動作用カム斜面35を形成してあり、ラッチボルト13の先端部13aをカム円盤11の前記錠止段部15に係合させて、第1空洞2からの錠ケース3の脱出を制止し、錠前ユニット4の鍵16によってカム円盤11を回転させて、カム円盤11の前記駆動カム面33でラッチボルト13の前記従動カム面34を押すことによって、ラッチボルト13の先端部分13aをカム円盤11の錠止段部15から押し出して、ラッチボルト13とカム円盤11の係合を解除し、錠ケース3の突出移動により受金ピン7と掛金体5の係合を解除するものである。
【0006】
【発明の作用】
請求項1の発明では、掛金体5と受金ピン7の係合によって防護対象物を施錠するには、施錠対象物に連結してある掛金体5の先端部分をハウジング1の受溝6に嵌め入れ、錠ケース3を第1空洞2内で押し動かして受金ピン7を前記受溝6内に突出させ、受金ピン7を掛金体5に差し込む。
このように錠ケース3を押し動かす過程において、カム円盤11の周縁肩部が先端部分13aのラッチ動作用カム斜面35を押すため、ラッチボルト13はバネ14の付勢に抗して後退移動させられる。受金ピン7が掛金体5に差し込み係合したとき、ラッチボルト13はバネ14の付勢によって前進移動し、ラッチボルト13の先端部分13aがカム円盤11の錠止段部15に係合する。
【0011】
このラッチボルト13との係合によってカム円盤11はハウジング1に対して移動不能に拘束され、受金ピン7を介してカム円盤11に連結されている錠ケース3もまた当該押し込み位置に拘束される。そのため、受金ピン7は掛金体5に差し込まれた施錠位置に拘束される。
施錠を解除するには、錠前ユニット4のロータ9の鍵孔に鍵16を挿入し、鍵16によってロータ9を所定方向に回す。このロータ9の回転に付随してカム円盤11が回転するため、カム円盤11の駆動カム面33によってラッチボルト13の従動カム面34が押されて、ラッチボルト13はバネ14の付勢に抗して後退移動させられ、ラッチボルト13の先端部分13aがカム円盤11の錠止段部15から脱出する。
【0012】
このようにしてカム円盤11がハウジング1に対する拘束から解放されるため、カム円盤11と受金ピン7と錠ケース3は第1空洞2と第2空洞10内を一体となって移動し、錠ケース3はハウジング1から突出することができる。
錠ケース3が所定長さまでハウジング1から突出したとき、受金ピン7は前記受溝6から脱出して前記受孔8側に退没し、受金ピン7が掛金体5から抜き取られる。これによって解錠動作が完了し、施錠対象物の錠止拘束が解除される。
【0013】
【発明の実施の形態】
図1から図28に示した実施例では、本発明の受金ピン抜差し型錠装置は、自動販売機の扉を筐体に対して錠止拘束するのに使用されている。
掛金体5はアーム状に形成されており、自動販売機の筐体21にボルト締めによって固着される軸受体22の割溝部23に掛金体5の基端部が嵌め込まれ、垂直枢軸24によって水平面内で旋回するように連結されている。垂直枢軸24と掛金体5の軸孔25の間にはカラー筒26が挿入されている。掛金体5の先端部分には受金ピン7が差し込まれる垂直透孔27を形成してある。垂直枢軸24はロックビス54によって軸受体22に締付け固定されている。
図29に示した実施例では、掛金体5は自動販売機の筐体21に直接固着されており、
水平面内では旋回しないものである。
【0014】
図2と図4及び図6から図9に示したように、ハウジング1の第1空洞2はハウジング1の下側端面に開口しており、第1空洞2の横断面は三つの角部を丸めた略四辺形状に形成されている。図10から図17に示したように錠ケース3は第1空洞2と同形の断面を有するため、第1空洞2に嵌め込まれた錠ケース3はハウジング1に対して回転することができない。
図1に示したようにハウジング1は背面1a側に形成したねじ孔32を利用して、中間にスペーサーまたは台座53を挿入して扉29の端面壁部にボルト締め固着される。図2と図3に示したように受溝6はハウジング1の正面と左右側面に開口させてハウジング1の上部に横長に形成されている。図1に示した実施例では、扉29を一側の蝶番軸(図示していない)を中心に閉鎖回転させた後、図28に示したように垂直枢軸24を中心に掛金体5を水平旋回させると、図1に示したように閉鎖位置に待ち受けている受溝6に掛金体5の先端部分が入り込む。
図29の実施例では、扉29を閉鎖回転させると、不動位置にある掛金体5の先端部分が見掛け上受溝6に入り込む。
【0015】
図2と図6に示したように受金ピン7が係合する受孔8は、受溝6の下側壁面と上側壁面の双方に形成されており、上側壁面の受孔8は盲孔に形成されている。ハウジング1の扉29に対する固着に当たっては、該受孔8の軸線上に掛金体5の垂直透孔27が来るように位置調整される。
図12と図15に示したように錠ケース3には、下面側に開口した錠前収納部28が形成されている。錠前収納部28の下方部分は大径の円形孔28aに形成され、中間部分は断面小判形孔28bに形成され、上端部分は小径の段付き円形孔28cに形成されている。段付き円形孔28cには丸棒状の受金ピン7の基端部が嵌挿されている。
【0016】
第2空洞10は第1空洞2よりも小径に形成され、その中央部に前記受孔8が形成されている。カム円盤11の中央透孔30に嵌挿された受金ピン7は直径方向の透孔55を通る固定ピン31によってカム円盤11に固着されている。カム円盤11が錠ケース3の上面に当接し、錠前収納部28の段付き円形孔28cの環状段面28dに受金ピン7の環状鍔部7aが当接しているため、受金ピン7とカム円盤11及び錠ケース3は一体となってハウジング1の縦軸方向に移動可能となっているとともに、受金ピン7とカム円盤11は錠ケース3に対して回転可能となっている。
【0017】
図21から図23に示したようにカム円盤11は、下面側周縁部の一部が切り欠きされて錠止段部15が形成されている。錠止段部15の一対の内壁面の奥部には傾斜角度45度の駆動カム面33が形成されている。
図24から図26に示したようにラッチボルト13は平板状に形成され、先端部分13aの側面部に傾斜角度45度の一対の従動カム面34が形成され、先端部分13aの下面部にラッチ動作用カム斜面35が形成されている。カム円盤11が回転するとき、駆動カム面33が従動カム面34を押すことによって、ラッチボルト13の先端部分13aがカム円盤11の錠止段部15から押し出される。
ラッチボルト13の基端部分の側面部には、図8に示したようにガイド孔12の途中の肩面36に係脱する停止突起37を形成してある。停止突起37と肩面36が係合することによって、ラッチボルト13は第2空洞10内への脱落を阻止される。
【0018】
ラッチボルト13の付勢用バネ14は圧縮コイルバネで構成されており、バネ14の一端部はラッチボルト13の基端部の丸孔38に挿入され、バネ14の他端部はバネ受板39の凹部40に挿入されている。バネ受板39はハウジング1の背面部の収容溝41に嵌めこまれ、ビス42によってハウジング1に締付け固着されている。図18から図20に示したようにバネ受板39には全体としてL字状をなすように延長板部43が形成されており、延長板部43の下端部にストッパー部材20が突設されている。
図13と図16に示したように錠ケース3の外側面の一つの角部には、上下方向に長い規制溝44が形成されており、図9に示したようにストッパー部材20が、ハウジング1の隔壁の開口56を通して規制溝44に挿入されている。
ストッパー部材20が規制溝44の上下壁面44a,44bに当接することによって、錠ケース3の押し動かし時と引出し時のストロークが決定されている。すなわち、ハウジング1の第1空洞2からの錠ケース3の突出を、取付機構19の操作が可能となる範囲内にストッパー部材20によって限定したので、第1空洞2から錠ケース3を完全に抜き取る場合とは異なり、錠ケース3及び錠前ユニット4の紛失や破損の危険性がない。
【0019】
錠前ユニット4としては、施錠位置においてのみ鍵16が抜差しされる公知構造のシリンダー錠が使用されている。錠ケース3の錠前収納部28は下向きに開口しており、錠前ユニット4はロータ9の鍵孔45を下向きにして装着されているため、不正解錠や不正破錠が困難になっている。
錠前ユニット4の固定本体46の頭部は円形に形成されており、図6に示したように錠ケース3の錠前収納部28の前記円形孔28aに嵌めこまれる。固定本体46の胴部は小判形断面に形成されており、錠前収納部28の前記小判形断面孔28bに嵌めこまれる。固定本体46の末端部分とロータ取付用ナット58は、錠前収納部28の前記段付き円形孔28cに嵌め込まれている。
【0020】
錠前ユニット4は、錠ケース3の横側面から操作される取付機構19によって錠ケース3に固定される。この取付機構19は、固定本体46の前記胴部のねじ山部に螺合される固定リング47と、錠ケース3の側面開口48から錠前収納部28に挿入されるU字状金具57とからなり、U字状金具57はビス49によって錠ケース3の中間壁部3aに締付け固定される。固定リング47の外周溝50にはU字状金具57の脚部突起51が係合しており、これによって錠前ユニット4の抜き取りが制止されている。
前記取付機構19は、鍵16の挿入回転によって錠ケース3をハウジング1の第1空洞2から突出させたとき、ハウジング1の外部に露出するようになっているから、ハウジング1を自動販売機等から取外さなくても、錠前ユニット4の点検や交換作業を行える簡便性に優れている
ロータ9の断面小判形の先端部9aは、図6に示したように受金ピン7の基端部の同形断面の連結孔52に嵌め込まれている。
【0021】
上記実施例では、ラッチボルト13とカム円盤11の係合を解除した解錠位置においては、鍵16が錠前ユニット4から抜き取れない構造になっており、鍵16が錠前ユニット4に拘束されているため、鍵16を引くことによって錠ケース3をハウジング1の第
1空洞2から的確に引き出することができる。
このように鍵16によって錠ケース3を牽引することができるため、ハウジング1の配置態様は第1空洞2の開口を下向きにした態様に限定されず、用途や適用場所に応じて適宜に変更することができる。
【0022】
また、上記実施例では、受金ピン7が嵌められる受孔8は、掛金体5が入り込む受溝6の相対向する二壁面に跨って形成されているため、受金ピン7が掛金体5と係合した施錠状態においては、受金ピン7はハウジング1によって両持支持されることになり、相当大きな外力が加えられても、掛金体5と受金ピン7の係合が破壊されることがなく、不法破錠に対する防護機能が増大する。
【0023】
【発明の効果】
以上のように請求項1の発明の受金ピン抜差し型錠装置では、ハウジング1の第1空洞2に錠ケース3を移動可能に収納し、ハウジング1の受溝6内に出入りして掛金体5に係合する受金ピン7を錠ケース3に相対回転可能に連結し、錠前ユニット4のロータ9に連結した受金ピン7をハウジング1の受孔8に嵌挿し、ハウジング1の第2空洞10に収容したカム円盤11を受金ピン7に連結し、ハウジング1のガイド孔12に嵌挿したラッチボルト13をカム円盤11に向かってバネ付勢し、ラッチボルト13をカム円盤11の側面の錠止段部15に係合させて、第1空洞2からの錠ケース3の脱出を制止するものであり、錠ケース3をハウジング1の第1空洞2に沿って押し動かすことによって、受金ピン7をハウジング1の受溝6に押し出し、この押し出した受金ピン7を受
溝6内の掛金体5に差し込むものであるから、施錠は操作者の手動操作によって操作者の目視下において実感的に完全になされることになり、施錠の確実性と信頼性に優れている。
また、錠前ユニット4の鍵16によってカム円盤11を回転させ、カム円盤11の駆動カム面33でラッチボルト13の従動カム面34を押すことによって、ラッチボルト13をバネ14の付勢に抗して後退移動させ、ラッチボルト13の先端部分13aをカム円盤11の錠止段部15から脱出させて、ラッチボルト13とカム円盤11の係合を解除すると、錠ケース3が解錠位置に移動し、受金ピン7が掛金体5から直ちに抜き取れらるものであるから、解錠操作の迅速性と確実性にも優れている。

[0006]
[Effects of the Invention]
In the invention of claim 1, in order to lock the object to be protected by the engagement of the latch body 5 and the receiver pin 7, the front end portion of the latch body 5 connected to the lock object is inserted into the receiving groove 6 of the housing 1. The lock case 3 is pushed and moved in the first cavity 2 so that the receiving pin 7 protrudes into the receiving groove 6, and the receiving pin 7 is inserted into the latch body 5.
In this process of pushing and moving the lock case 3, the peripheral shoulder of the cam disk 11 pushes the latching cam inclined surface 35 of the tip portion 13 a, so that the latch bolt 13 moves backward against the bias of the spring 14. It is done. When the receiving pin 7 is inserted into and engaged with the latch body 5, the latch bolt 13 is moved forward by the bias of the spring 14, and the tip portion 13 a of the latch bolt 13 is engaged with the locking step portion 15 of the cam disk 11. .
