Description

【０００１】
【産業上の利用分野】
本発明は、自動販売機、コンイロッカーなどの開閉扉に装着される錠前の錠把手とシリンダー錠との固定構造に関する。
【０００２】
【従来の技術】
従来、自動販売機の錠前の錠把手とシリンダー錠との固定構造として、実公平６ー３９４１８号公報に一例が開示されている。この実施例の主要部を図１０及び図１１に示して説明すると次の通りである。
【０００３】
すなわち、５１は自動販売機の開閉扉に固定される錠前のハンドルケースで、
このハンドルケース５１は、鍔状に形成された取付け部５２と、この取付け部に直交方向に連設する円筒部５３とから成る。そして、前記取付け部５２には嵌合部５４が形成され、また円筒部５３には係合孔５５が形成されている。
【０００４】
５６はハンドルケース５１内に摺動可能に嵌合する錠把手（ハンドル）で、この錠把手５６は図示しないバネでハンドルケース５１の外方向に常時付勢されている。錠把手５６は前記嵌合部５４に嵌合する把手部５７と、この把手部５７に直交方向に連設する筒状部５８とから成り、前記筒状部５８に自動販売機の本体側の係合部と係合する係合ボルト５９が貫通状態に設けられている。
【０００５】
６０は錠把手５６の前方部に取り外し可能に嵌合するシリンダー錠で、このシリンダー錠６０にはキー６１が差し込まれる。シリンダー錠６０の外周壁には、フラット面６２と、複数本のネジ状係止溝６３とが形成され、前記ネジ状係止溝６３には半径方向にメネジ６４が形成されている。
【０００６】
そこで、錠前の錠把手５６とシリンダー錠６０との固定構造について説明すると、図１０で示すように錠把手５６の筒状部５８の前部には半径方向に所要間隔を有して２個の角型貫通孔６６が対設形成され、これらの貫通孔６６、６６に固定手段としての断面コ字型の係合具６５がそれぞれ差し込まれる。係合具６５は左右の係合脚部の先端部に係止ネジ部６７、６７をそれぞれ有し、また係合脚部を連結する水平部には前記筒状部５８の適宜部位に形成された丸型のネジ用貫通孔６８と連通状態に符合する止めネジ６９係止用孔７０が形成されている。
【０００７】
しかして、図１１で示すように止めネジ６９を前記係止用孔７０及びネジ用貫通孔６８に差し込みかつ、止めネジ６９を締め付けると、係合具６５の係止ネジ部６７、６７が筒状部５８の内側に突出してシリンダー錠６０のメネジ６４に螺合し、これによりシリンダー錠６０が錠把手５６に固定される。一方、このように固定されたシリンダー錠６０を錠把手５６から取外す時は、まず止めネジ６９を緩めて係合具６５から取外し、次に係合具６５の係止ネジ部６７、６７をシリンダー錠６０のネジ状係止溝６３からその係合を解除させる。この場合概して係合具６５を錠把手５６から取り外したうえで、シリンダー錠６０を錠把手５６から引き抜く。
【０００８】
しかしながら、上記構成の錠把手５６とシリンダー錠６０との固定構造に於いては、係合具６５と止めネジ６９とは別体的に組み合わせられているので、シリンダー錠６０を錠把手５６から引き抜く場合は、両方の部材６５、６９を一体的にシリンダー錠６０のネジ状係止溝６３から係合解除あるいは錠把手５６の筒状部５８から取り外しをすることができない。したがって、次に列挙するような欠点があった。
(1)止めネジ６９を緩めても直ちに係合具６５をシリンダー錠６０のネジ状係止溝６３から係合解除できるとは限らない。
(2)止めネジ６９を係合具６５から取り外した場合、係合具６５がそのまま錠把手５６の筒状部５８に残っている。したがって、係合具６５を筒状部５８から適宜に取り外さなければならないので、手間がかかる。
(3)シリンダー錠６０を交換する場合、両方の部材６５、６９がいわゆるバラバラに成るので、小さな止めネジ６９を見失う場合がしばしばある。
【０００９】
【発明が解決しようとする課題】
本発明は以上のような従来の欠点に鑑み、第１の目的はシリンダー錠を錠把手から引き抜く場合に、固定手段としての係合具を簡単に係合解除することができると共に、止めネジを介して係合具を錠把手の筒状部から簡単に取り外すことができることである。また第２の目的は止めネジを締め付けた際に、係合具と止めネジを一体的に結合する結合支持部材が変形、破損、脱落などしないことである。
第３の目的はシリンダー錠を簡単に交換することができることである。
【００１０】
【課題を解決するための手段】
本発明の錠前の錠把手とシリンダー錠との固定構造は、開閉扉に固定される錠前のハンドルケース１と、ハンドルケース１内に摺動可能に嵌合する錠把手６と、この錠把手の筒状部８に取り外し可能に嵌合するシリンダー錠２０と、前記筒状部８の前部に形成された係合具用貫通孔２６に係止脚部３１が差し込まれ、かつ、前記シリンダー錠２０の外壁に形成された係止溝２３と係合する係止部３２を前記係止脚部の先端部に有する断面Ｌ字型或いは断面コ字型の係合具３０と、この係合具のネジ係止用孔３４及び前記筒状部８のネジ用貫通孔２８に差し込まれ、係合具の係止部３２がシリンダー錠２０の係止溝２３と係合した状態で該係合具を筒状部８に固定する止めネジ４０とを備え、前記止めネジ４０のネジ部４０ｂには嵌合取付部４１を形成し、この嵌合取付部４１には該ネジ部４０ｂと交差状態に突出すると共に、前記止めネジを緩めたときに前記係合具も一緒に筒状部８から引き抜くための結合支持部材４２を取付け、一方、前記筒状部８の係合具用貫通孔２６と連通する嵌合凹所あるいは嵌合溝８ａには、前記結合支持部材４２を前記止めネジと共に回転可能に収納する収納凹所２７が形成されていることを特徴とする。
【００１１】
上記構成に於いては、前記止めネジ４０のネジ部４０ｂに嵌合取付部４１を形成し、この嵌合取付部４１には該ネジ部４０ｂと交差状態に突出する結合支持部材４２Ａを取付けると共に、係合具３０Ａの水平部３３Ａの内面３３ａに結合支持部材４２Ａを前記止めネジと共に回転可能に収納する収納凹所あるいは収納溝２７Ａを形成しても良い。
【００１２】
【作用】
まず係合具の止めネジ係止用孔に止めネジを差し込んだ後にそのネジ部の嵌合取付け部に結合支持部材４２を嵌め込む。これにより止めネジと係合具とが一体になる。
【００１３】
次に係合具の係止脚部を錠把手の筒状部の貫通孔に差し込むと同時に、止めネジを締め付け可能な状態にする。この時結合支持部材は、錠把手の筒状部に形成された収納凹所又は係合具の水平部の内面に形成された収納凹所に完全に収納される。そこで、止めネジを締め付けると、そのネジ部がシリンダー錠のメネジ又は錠把手の筒状部のメネジに螺合し、これによりシリンダー錠が錠把手に固定される。この時止めネジを強力に締め付けても、係合具の圧接力が結合支持部材に加わらない。
【００１４】
一方、シリンダー錠を錠把手から取外す時は、止めネジを緩める。そうすると、止めネジと共に結合支持部材は収納凹所内で回転すると共に、係合具の係止ネジ部がシリンダー錠のネジ状係止溝から直ちにその係合が解除される。そして、止めネジを筒状部から引き抜くと、結合支持部材を介して係合具も一緒に筒状部から外れる。
【００１５】
【実施例】
以下、図面に示す実施例により本発明を詳細に説明する。なお、本発明の各実施例を説明するにあたって、従来の実施例と同一の部分は簡単に説明する。
図１ないし図５は第１実施例である。１は錠前のハンドルケースで、このハンドルケース１は鍔状に形成された取付け部２と、この取付け部に連設する円筒部３とから成る。ハンドルケース１は断面がＴ字型状に形成されているが、断面Ｌ型状であっても良い。取付け部２には嵌合部４が形成され、また円筒部３には係合孔５が形成されている。
【００１６】
６はハンドルケース１内に直接又はガイド筒を介して摺動可能に嵌合する断面Ｔ字型状の錠把手で、この錠把手６は後述するバネでハンドルケース１の外方向に常時付勢されている。本実施例では錠把手６は、ハンドルケース１内に直接摺動可能に嵌合する。錠把手６もハンドルケース１の断面形状に対応して断面Ｌ型状に形成しても良い。
【００１７】
しかして、錠把手６は前記嵌合部４に嵌合する把手部７と、この把手部７に連設する筒状部８とから成り、前記筒状部８に係合ボルト９が後端部の透孔１０を介して貫通状態に設けられている。
【００１８】
１１はこの係合ボルト９に巻装され、かつ、錠把手６をハンドルケース１の外方向に常時付勢するバネである。このバネ１１は錠把手６の筒状部８の後端面とハンドルケース１の円筒部３の後端部の内面との間に介在している。
【００１９】
１２は錠把手６の筒状部８の前方部よりの部位に回動可能に内装された駆動カムで、この駆動カム１２にはロック片１３が係合している。ロック片１３はロック片１３用孔１４を介してハンドルケース１の係合孔５と係脱する。またロック片１３は圧縮バネ１５で前記係合孔５の方向に常時付勢されている。
【００２０】
２０は錠把手６の前方部に取り外し可能に嵌合するシリンダー錠で、このシリンダー錠２０にはキー２１が差し込まれる。シリンダー錠２０の外周壁には、両側にフラット面２２が形成され、またフラット面２２を除いたその他の部分には複数本のネジ状係止溝２３が形成されている。そして、前記ネジ状係止溝２３には半径方向にメネジ２４が１個又は２個、本実施例では１個形成され、さらにシリンダー錠２０にはキー２１操作で回動しかつ前記駆動カム１２と嵌合する駆動軸１６が設けられている。
【００２１】
そこで、錠前の錠把手６とシリンダー錠２０との固定構造について説明する。図１及び図２で示すように錠把手６の筒状部８の前部には半径方向に１個の係合具用貫通孔２６が形成されている。この貫通孔２６は、従来の実施例のように筒状部８の上下の部位にそれぞれ形成しても良い。また錠把手６の筒状部８の前部には、前記貫通孔２６と連通し、かつ、後述する係合具３０の水平部３３が嵌合
する嵌合凹所あるいは嵌合溝８ａが形成されている。そして、嵌合凹所あるいは嵌合溝８ａには、さらに後述する結合支持部材用凹所２７が形成されている。この結合支持部材用凹所２７は、結合支持部材４２が回転できる広さを有し、半径方向にネジ用貫通孔２８が少なくとも１個形成されている。そこで、前記貫通孔２６には固定手段としての断面Ｌ字型の係合具３０が差し込まれる。この係合具３０の形態は、例えば係合具用貫通孔２６が対設形成されている場合は、断面コ字型など適宜の形状に形成しても良い。
【００２２】
係合具３０は図３で示すように垂直方向の係合脚部３１の先端部に爪状ないしネジ状の係止部３２を有し、また係合脚部３１と直交方向に連結する水平部３３には前記筒状部８に形成された貫通孔２８と連通状態に符合する止めネジ係止用孔３４が形成されている。係合具３０の内面３３ａは筒状部８の嵌合凹所あるいは嵌合溝８ａの底面と面接触（当接）する。
【００２３】
４０は係合具３０の前記止めネジ係止用孔３４及びネジ用貫通孔２８に差し込まれ、かつ、シリンダー錠２０のメネジ２４に螺合する止めネジである。この止めネジ４０の頭部４０ａと連設するネジ部４０ｂ（ネジのない部分も含む。）には、半径方向（図４では水平方向）に水平貫通孔、水平溝などの嵌合取付け部４１が形成されている。
【００２４】
４２は止めネジ４０のネジ部４０ｂと交差状態に突出するように前記嵌合取付け部４１に取り付けられ、かつ、前述した収納凹所２７に収納される結合支持部材である。この結合支持部材４２は、本実施例では図５で示すように望ましくは「Ｅリング」の形状をしている。結合支持部材４２は収納凹所２７に収納されても、嵌合凹所あるいは嵌合溝８ａの底面８ｂから突出しない。結合支持部材４２は強靭であることが望ましい。
【００２５】
上記構成に於いては、まず係合具３０の止めネジ係止用孔３４に止めネジ４０を差し込み、次に貫通したネジ部４０ｂの嵌合取付け部４１に結合支持部材４２を嵌め込む。これにより止めネジ４０と係合具３０との一体化が図れる。
【００２６】
次に係合具３０の係止脚部３１を貫通孔２６に、一方、止めネジ４０のネジ部４０ｂをネジ用貫通孔２８に同時に差し込むようにする。そこで、止めネジ４０を締め付ける。この時結合支持部材４２は図４で示すように収納凹所２７に完全に収納される。止めネジ４０を締め付けると、そのネジ部４０ｂがシリンダー錠２０のメネジ２４に螺合し、これによりシリンダー錠２０が錠把手６に固定される。この時止めネジ４０を強力に締め付けても、係合具４０の圧接力が結合支持部材４２に加わらない。
【００２７】
一方、上記のように固定されたシリンダー錠２０を錠把手６から取外す時は、止めネジ４０を緩める。そうすると、止めネジ４０と共に結合支持部材４２は収納凹所２７内で回転すると共に、係合具３０の係止ネジ部３２がシリンダー錠２０のネジ状係止溝２３から直ちにその係合が解除される。そして、止めネジ４０を筒状部８から引き抜くと、結合支持部材４２を介して係合具３０も一緒に筒状部８から外れる。そこで、シリンダー錠２０を錠把手６から引き抜く。
【００２８】
【異なる実施例】
図６乃至図９に示す本発明の異なる実施例につき説明する。なお、異なる実施例の説明にあたって前記本発明の第１実施例と同一の部分には同一の符号を付し、重複する説明を省略する。
【００２９】
まず図６乃至図８に示す第２実施例の錠前の錠把手６Ａとシリンダー錠２０Ａとの固定構造に於いて、前記実施例と主に異なる点は、結合支持部材４２Ａを収納する収納凹所２７Ａを錠把手６Ａの筒状部８Ａの前部ではなく、断面Ｌ型の係合具３０Ａに形成した点である。
【００３０】
しかして、収納凹所２７Ａは係合具３０Ａの水平部３３Ａの内面３３ａに形成されている。ここで「収納凹所２７Ａ」とは、普通一般の凹所のみならず、図７で示すような切欠溝も含まれる。このように構成しても第１実施例と同一の作用・効果がある。
【００３１】
なお、本発明の第１及び第２実施例に於いて、シリンダー錠２０（２０Ａ）の外壁にメネジ２４が形成され、このメネジ２４に係合具３０（３０Ａ）をシリンダー錠２０（２０Ａ）の係止溝２３に係合させるための止めネジ４０が螺合する旨を説明したが、前記シリンダー錠２０（２０Ａ）に必ずしもメネジ２４を形成せず、図９で示す第３実施例のように錠把手６（６Ａ）の筒状部８（８Ａ）に止めネジ４０が螺合するメネジ２４Ａを形成しても良い。この場合係合具３０（３０Ａ）は止めネジ４０を介して錠把手６（６Ａ）の筒状部８（８Ａ）に固定され
る。
【００３２】
【発明の効果】
以上の説明から明らかなように、本発明にあっては次に列挙するような効果がある。
（１）止めネジと係合具とが結合支持部材を介して一体的に結合しているので、シリンダー錠を錠把手から引き抜く場合に、固定手段としての係合具をシリンダー錠から簡単に係合解除することができる。
（２）また止めネジを介して係合具を錠把手の筒状部から簡単に取り外すことができる。
（３）錠把手の筒状部に又は係合具の水平部の内面に結合支持部材用の収納凹所が形成されているので、止めネジを強力に締め付けても、係合具の圧接力が結合支持部材に加わらない。したがって、結合支持部材が変形、破損、脱落などしない。
（４）シリンダー錠を簡単に交換することができる。

[Industrial application fields]
The present invention relates to a fixing structure of a lock handle of a lock and a cylinder lock mounted on an opening / closing door of a vending machine, a conic locker or the like.
[0002]
[Prior art]
Conventionally, an example is disclosed in Japanese Utility Model Publication No. 6-39418 as a fixing structure between a lock handle and a cylinder lock of a vending machine. The main part of this embodiment will be described with reference to FIGS.
[0003]
That is, 51 is a lock handle case fixed to the door of the vending machine.
The handle case 51 includes an attachment portion 52 formed in a bowl shape, and a cylindrical portion 53 that is connected to the attachment portion in an orthogonal direction. A fitting portion 54 is formed in the mounting portion 52, and an engagement hole 55 is formed in the cylindrical portion 53.
[0004]
Reference numeral 56 denotes a lock handle (handle) that is slidably fitted into the handle case 51. The lock handle 56 is always urged outward of the handle case 51 by a spring (not shown). The lock handle 56 includes a handle portion 57 that is fitted to the fitting portion 54 and a cylindrical portion 58 that is continuous with the handle portion 57 in the orthogonal direction. The cylindrical portion 58 is provided on the main body side of the vending machine. An engagement bolt 59 that engages with the engagement portion is provided in a penetrating state.
[0005]
A cylinder lock 60 is detachably fitted to the front portion of the lock handle 56, and a key 61 is inserted into the cylinder lock 60. A flat surface 62 and a plurality of screw-like locking grooves 63 are formed on the outer peripheral wall of the cylinder lock 60, and female screws 64 are formed in the screw-like locking grooves 63 in the radial direction.
[0006]
Therefore, the fixing structure of the lock handle 56 and the cylinder lock 60 will be described. As shown in FIG. 10, the front portion of the cylindrical portion 58 of the lock handle 56 has two gaps with a required distance in the radial direction. Square-shaped through holes 66 are formed to be opposite to each other, and engagement tools 65 having a U-shaped cross section as fixing means are respectively inserted into these through holes 66 and 66. The engagement tool 65 has locking screw portions 67 and 67 at the distal end portions of the left and right engagement leg portions, respectively, and a round portion formed at an appropriate portion of the cylindrical portion 58 on the horizontal portion connecting the engagement leg portions. A set screw 69 locking hole 70 is formed that matches the state of communication with the screw through hole 68 of the mold.
[0007]
Then, as shown in FIG. 11, when the set screw 69 is inserted into the locking hole 70 and the screw through hole 68 and the set screw 69 is tightened, the locking screw portions 67 and 67 of the engagement tool 65 are cylinders. The cylinder lock 60 is fixed to the lock handle 56 by projecting to the inside of the shaped portion 58 and screwed into the female screw 64 of the cylinder lock 60. On the other hand, when the cylinder lock 60 fixed in this way is removed from the lock handle 56, the set screw 69 is first loosened and removed from the engaging tool 65, and then the locking screw portions 67, 67 of the engaging tool 65 are removed from the cylinder. The engagement is released from the screw-like locking groove 63 of the lock 60. In this case, the engagement tool 65 is generally removed from the lock handle 56 and then the cylinder lock 60 is pulled out of the lock handle 56.
[0008]
However, in the fixing structure of the lock handle 56 and the cylinder lock 60 configured as described above, the engagement tool 65 and the set screw 69 are combined separately, so that the cylinder lock 60 is pulled out from the lock handle 56. In this case, both the members 65 and 69 cannot be disengaged integrally from the screw-like locking groove 63 of the cylinder lock 60 or removed from the cylindrical portion 58 of the lock handle 56. Therefore, there are the following disadvantages.
(1) Even if the set screw 69 is loosened, it is not always possible to disengage the engaging tool 65 from the threaded locking groove 63 of the cylinder lock 60.
(2) When the set screw 69 is removed from the engaging tool 65, the engaging tool 65 remains in the cylindrical portion 58 of the lock handle 56 as it is. Therefore, since the engaging tool 65 must be appropriately removed from the cylindrical portion 58, it takes time and effort.
(3) When the cylinder lock 60 is replaced, since both the members 65 and 69 are so-called apart, the small set screw 69 is often lost.
[0009]
[Problems to be solved by the invention]
In view of the above-described conventional drawbacks, the present invention has a first object in that when the cylinder lock is pulled out from the lock handle, the engaging tool as the fixing means can be easily disengaged, and the set screw can be used. The engagement tool can be easily removed from the cylindrical portion of the lock handle. The second purpose is to prevent the coupling support member that integrally couples the engaging tool and the set screw from being deformed, damaged, or dropped when the set screw is tightened.
The third purpose is that the cylinder lock can be easily changed.
[0010]
[Means for Solving the Problems]
The lock structure of the lock and the cylinder lock according to the present invention includes a lock handle case 1 fixed to an opening / closing door, a lock handle 6 slidably fitted in the handle case 1, and the lock handle. A cylinder lock 20 that is detachably fitted to the tubular portion 8, a locking leg portion 31 is inserted into an engagement tool through-hole 26 formed in the front portion of the tubular portion 8, and the cylinder lock An engaging tool 30 having an L-shaped cross section or a U-shaped cross section having a locking portion 32 that engages with a locking groove 23 formed on the outer wall 20 at the distal end of the locking leg, and the engaging tool The engagement tool is inserted into the screw locking hole 34 and the screw through hole 28 of the cylindrical portion 8, and the engagement part 32 of the engagement tool is engaged with the locking groove 23 of the cylinder lock 20. And a set screw 40 for fixing the screw to the cylindrical portion 8. The fitting attachment portion 41 protrudes in a state intersecting with the screw portion 40b, and when the set screw is loosened, the coupling support member for pulling out the engagement tool together from the tubular portion 8 is formed. On the other hand, in the fitting recess or fitting groove 8a that communicates with the engagement tool through hole 26 of the tubular portion 8, the coupling support member 42 is housed rotatably together with the set screw. A recess 27 is formed.
[0011]
In the above-described configuration, the fitting attachment portion 41 is formed in the screw portion 40b of the set screw 40, and the fitting attachment portion 41 is attached with the coupling support member 42A protruding in a state intersecting with the screw portion 40b. A housing recess or housing groove 27A may be formed in the inner surface 33a of the horizontal portion 33A of the engaging tool 30A so that the coupling support member 42A is rotatably housed together with the set screw .
[0012]
[Action]
First, a set screw is inserted into the set screw locking hole of the engagement tool, and then the coupling support member 42 is fitted into the fitting mounting portion of the screw portion. Accordingly, the set screw and the engaging tool are integrated.
[0013]
Next, the locking leg portion of the engagement tool is inserted into the through hole of the cylindrical portion of the lock handle, and at the same time, the set screw can be tightened. At this time, the coupling support member is completely stored in the storage recess formed in the cylindrical portion of the lock handle or the storage recess formed in the inner surface of the horizontal portion of the engaging tool. Therefore, when the set screw is tightened, the screw portion is screwed into the female screw of the cylinder lock or the female screw of the cylindrical portion of the lock handle, thereby fixing the cylinder lock to the lock handle. At this time, even if the set screw is tightened strongly, the pressure contact force of the engagement tool is not applied to the coupling support member.
[0014]
On the other hand, when removing the cylinder lock from the lock handle, loosen the set screw. Then, the coupling support member rotates together with the set screw in the housing recess, and the engagement screw portion of the engagement tool is immediately released from the threaded engagement groove of the cylinder lock. Then, when the set screw is pulled out from the tubular portion, the engaging tool is also detached from the tubular portion through the coupling support member.
[0015]
