【発明が解決しようとする課題】
上記パチンコ機用施錠装置は、パチンコ機の前面枠を良好に施錠できるものの、針金などを用いた不正解錠に対し、対策が施されていないという問題があった。すなわち、パチンコホールでは、近年、営業中にパチンコ機の前面枠やガラス枠を不正に解錠し、本体枠内の遊技プログラムを格納したＲＯＭなどを不正なものと取り替えてしまい、多くの入賞球を不正に払い出すようにする不正行為が行われる事件が発生している。このような不正解錠は、通常、本体枠と前面枠の隙間から針金や線材などを差込み、針金の先端で施錠装置の連結杆やガラス枠施錠杆を引っ掛けて、解錠方向にそれを動かすことにより行われている。このために、針金などを用いて行われる不正解錠を未然に防止することができるパチンコ機用施錠装置が要望されていた。
【０００６】
本発明は、上記の課題を解決するためになされたもので、針金などを用いて行われる不正解錠を未然に防止することができるパチンコ機用施錠装置を提供することを目的とする。
【０００７】
【課題を解決するための手段】
上記の目的を達成するために、本発明のパチンコ機用施錠装置は、縦長の基枠の上部と下部に鉤部材が傾動可能に枢支され、基枠の内側に連結杆が摺動可能に配設され、連結杆の上端と下端に鉤部材が連結杆の上下摺動により傾動するように連結され、基枠の取付板にシリンダ錠がその錠軸を内側に差込むように固定され、錠軸の先端に連結杆と係合可能なカム板が固定され、シリンダ錠の操作によりカム板を介して連結杆を摺動させ、鉤部材を傾動させて前面枠を解錠するパチンコ機用施錠装置において、基枠には連結杆が施錠位置にあるとき、連結杆をロックするロック部材が設けられ、ロック部材は、連結杆の係止部に係止する係止部を有すると共に、カム板に係合する係合部を有して、基枠に回動可能に軸支され、ロック部材はカム板が解錠側に回動されたとき、ロックを解除するように構成され、シリンダ錠の操作により鉤部材を傾動させて解錠したとき、鉤部材と連結杆の解錠状態を保持する解錠保持部材が設けられ、解錠保持部材は、基枠に設けた係止凹部に係止可能な係止部を有して、連結杆に回動可能に軸支され、前面枠を本体枠側に閉じたとき本体枠側の部分に当って回動し解錠状態の保持を解除するように構成されたことを特徴とする。
【０００９】
また、上記ロック部材は、カム板が解錠側に回動されたとき、カム板の係合凸部に係合する係合部を有し、カム板の係合凸部の回動によりロック部材が回動して、連結杆のロックを解除する構造とすることができる。
【００１０】
【作用】
このような構成のパチンコ機用施錠装置では、キーをシリンダ錠に差し込んでその錠軸を回すと、カム板が回動し、このとき、カム板の係合凸部がロック部材を動かして、その係止部と連結杆の係止部との係合を外し、その後、カム板の係合凸部が連結杆の係合部に係合して連結杆を摺動させる。このとき、連結杆の摺動により鉤部材が解錠位置に傾動し、本体枠側の受け金具との係合を外し、解錠される。また同時に、解錠保持部材がその係止部を支持板の係止凹部に嵌入させて、連結杆を解錠位置に保持し、解錠状態が保持される。
【００１１】
一方、開いた状態の前面枠を本体枠に対し閉じると、先ず、施錠装置の解錠保持部材が本体枠側の一部に当たって、解錠保持部材がその係止部を基枠の係止凹部から外すように動作し、これにより解錠の保持が外れ、連結杆はコイルばねの付勢力により施錠側に摺動し、上下の鉤部材は施錠可能な状態となるから、鉤部材が本体枠側の受け金具に当ったとき、そこに係止され、施錠状態となる。
【００１２】
そして、この施錠状態では、ロック部材の係止部が連結杆の係止部に係止され、連結杆がロックされているため、キー以外の手段、例えば針金などにより連結杆を解錠方向に動かそうとしても動かず、また、鉤部材を解錠側に傾動させようとしても、連結杆が摺動しないために傾動しない。したがって、不正に針金などを差し込んで鉤部材や連結杆にその先端を引っ掛けてそれを動かし、不正に解錠しようとする不正解錠を防止することができる。
【００１３】
【発明の実施の形態】
以下、本発明の実施例を図面に基づいて説明する。図１は施錠装置の正面図を、図２はその左側面図を示し、図３はその右側面図を、図４はその左側面図を、図５はその背面図を各々示している。１は縦長の基枠で、取付板２と支持板３を断面略Ｌ形に曲折して一体成形され、取付板２には複数の取付孔が穿設され、また、後述のシリンダ錠７を取り付けるための開口部が形成される。
【００１４】
さらに、取付板２の上部と下部にはその一部を背面側に切り起こして支持板片３ａ，３ｂが支持板３に沿って支持板３とは別に形成されている。そして、それらの上下の支持板片３ａ，３ｂに、軸ピン４ａ，５ａを介して鉤部材４，５が各々傾動（回動）可能に軸支され、鉤部材４，５は下側に傾動可能に背面側に突出する。支持板片３ａ，３ｂと支持板３の間に連結杆６が上下に摺動可能に配設され、連結杆６の上端と下端に各々上下の鉤部材４，５の下端部がピン４ｂ、５ｂで連結される。したがって、連結杆６の上方への摺動に伴い、鉤部材４，５は水平位置から下方の解錠位置に傾動する。鉤部材４，５は図２に示すように、上側に開口したフック部を有して形成され、連結杆６を上方に摺動させると、鉤部材４，５はその軸ピン４ａ，５ａを支点に下方に傾動し、ロックが解除される構造である。
【００１５】
図４に示すように、シリンダ錠７はその元部にフランジ７ａを有し、基枠１の取付板２の開口部にその内側から挿入し、フランジ７ａを取付板２にねじ止めして固定される。シリンダ錠７の錠軸にはカム板８が固定され、カム板８には、取付板２側に曲折された第一係合凸部８ａと連結杆６側に延びる第二係合凸部８ｂが設けられる。図６に示すように、上記連結杆６の対応個所に係合部６ｂが内側に曲げて形成され、カム板８が図４、図６、図８の反時計方向に回動したとき、第一係合凸部８ａと係合部６ｂが係合して連結杆６を上方に移動させる。
【００１６】
さらに、図５、図６に示すように、連結杆６の係合部６ｂの少し上部には係止部６ａが内側に曲折されて形成される。この係止部６ａは、後述のロック部材１０の係合部１１ａに係合して、連結杆６の上方への移動を阻止する。さらに、連結杆６と支持板３の間に、ガラス枠用解錠杆１８が摺動可能に配設される。このガラス枠用解錠杆１８には、図５に示すように、作動部１８ａが支持板３から側方に突出して設けられ、ガラス枠用解錠杆１８が上記カム板８の第二係合凸部８ｂによって下方に摺動したとき、作動部１８ａが図示しないパチンコ機の金枠に設けたガラス枠施錠具の解錠片に作用して、ガラス枠施錠具を解錠動作させる。このためにガラス枠用解錠杆１８のカム板８との対応個所に、係合部１８ｂが設けられ、カム板８が図６の時計方向に回動した時、第二係合凸部８ｂと係合する。
【００１７】
ロック部材１０は、シリンダ錠７つまりカム板８の回動によってのみ連結杆６の移動を許容し、それ以外のときは連結杆６をロック状態とする部材で、取付板２の上に軸ピン１３によって回動可能に軸支され、コイルばね１４により、連結杆６側に近づけるように付勢される。図５、図６に示すように、ロック部材１０には、その下端に、カム板８の第二係合凸部８ｂが係合可能な係合部１１ａが内側に湾曲して形成され、その係合部１１ａの少し上に、連結杆６の係止部６ａと係合可能な係止部１１ｂが段部として形成される。
【００１８】
このロック部材１０は通常時、その係止部１１ｂを係止部６ａに係合させて連結杆６の解錠方向への移動をロックしている。そして、シリンダ錠７によりカム板８が図６の反時計方向に回動したとき、カム板８の第二係合凸部８ｂがロック部材１０の係合部１１ａに当接して、それを内側に回動させ、係止部１１ｂと係止部６ａの係合を外し、カム板８による連結杆６の移動を可能とする。
【００１９】
ところで、鉤部材４，５が施錠位置にあるとき、連結杆６が常時ロック部材１０によってロックされているのでは、解錠操作の後、前面枠を開き、シリンダ錠７つまりカム板８を戻した状態でも、連結杆６及び鉤部材４，５がロックされた状態であるから、前面枠を閉じたとき、自動的に施錠することができない。
【００２０】
このために、シリンダ錠７を操作してカム板８を回動させ、解錠を行ったとき、連結杆６を解錠位置に保持するために解錠保持部材１５が、連結杆６に軸ピン１６によって回動可能に軸支される。この解錠保持部材１５にはその下端に係止部１５ｂが設けられ、係止部１５ｂは解錠時、連結杆６の係合凹部６ｃと支持板３の係止凹部３ｃに嵌入して連結杆６の動きをロックする。すなわち、支持板３の対応位置に係止凹部３ｃが形成され、連結杆６にも対応位置に係合凹部６ｃが形成され、解錠保持部材１５はコイルばね１７によって、その係止部１５ｂを係合凹部１５ｂと係止凹部３ｃに嵌入するように付勢されている。
【００２１】
また、解錠保持部材１５の上部には凸部１５ａが背面側に突出して設けられ、この凸部１５ａは図７に示すように、シリンダ錠７をキーにより解錠し鉤部材４，５を解錠位置に傾動させた状態で、背面側に突出する。そして、前面枠が閉じた際には、凸部１５ａが本体枠側に設けた当て部２４に当たり、このとき、図１２のように回動し、連結杆６の動きを許容し、鉤部材４，５を傾動させて施錠が可能となる。
【００２２】
一方、キーをシリンダ錠７に差し込んで解錠操作したとき、図９のように、カム板８が回動して、ロック部材１０を内側に動かしてロック部材１０による連結杆６のロックを外し、連結杆６を上方に摺動させるが、このとき、図１０に示すように、連結杆６が所定位置まで摺動したとき、解錠保持部材１５の係止部１５ｂが係止凹部３ｃに嵌入して係止され、連結杆６が解錠位置で保持される構造となっている。
【００２３】
このように構成された施錠装置は、図１１、図１２に示すように、パチンコ機の前面枠２１の内側に本体枠２０側を向けて縦に固定され、本体枠２０側の対応位置には、鉤部材４，５が係止される受け金具２２，２３が固定される。また、本体枠２０側には解除保持部材１５の凸部１５ａに対応した個所に、前面枠２１を閉じたときにその凸部１５ａが当たる当て部２４が設けられる。前面枠２１内にはガラス枠を有した図示しない金枠が設けられ、金枠にはガラス枠用のガラス枠施錠具が設けられる。上記ガラス枠用解錠杆１８の作動部１８ａはこのガラス枠施錠具の解錠用レバーの真上に位置する。
【００２４】
このパチンコ機用施錠装置では、キーをシリンダ錠７に差し込んで、右に回すと、カム板８が同方向に回動し、このとき、図８のように、カム板８の第二係合凸部８ｂがロック部材１０を内側に回動させて、その係止部１１ｂと連結杆６の係止部６ａとの係合を外し、その後、カム板８の第一係合凸部８ａが連結杆６の係合部６ｂに係合して連結杆６を上方に摺動させる。このとき、連結杆６の上への摺動により鉤部材４，５が図７のように解錠位置に傾動したとき、図１０のように、解錠保持部材１５がコイルばね１７の付勢力に伴ってその係止部１５ｂを支持板３の係止凹部３ｃに嵌入させ、連結杆６と鉤部材４，５を解錠位置に保持し、これで解錠状態となる。
【００２５】
したがって、パチンコ機の前面枠２１を解錠して開いたときには、施錠装置は図７のように上下の鉤部材４，５を解錠位置に傾斜した状態となり、その状態が保持される。そして、この前面枠２１を本体枠２０に対し閉じると、図１１に示すように、先ず、施錠装置の解錠保持部材１５の凸部１５ａが本体枠２０側の当て部２４に当たり、内側に戻されるように回動する。これにより、解錠保持部材１５の係止部１５ｂが支持板３の係止凹部３ｃから退出して、解錠の保持が外れ、連結杆６はコイルばね１７の付勢力により下方に摺動し、上下の鉤部材４，５が上側に回動し、図１２のように、受け金具２２，２３に鉤部材４，５が係止され、施錠状態となる。
【００２６】
この施錠状態では、ロック部材１０の係止部１１ｂが連結杆６の係止部６ａに係止されているため、キー以外の手段、例えば針金などにより連結杆６を解錠方向（上方）に動かそうとしても動かず、また、鉤部材４，５を解錠側に傾動させようとしても、連結杆６が摺動しないために傾動しない。したがって、不正に針金などを差し込んで鉤部材や連結杆にその先端を引っ掛けてそれを動かし、不正に解錠しようとする不正解錠を防止することができる。
【００２７】
そして、前面枠２１を解錠する場合は、上記のように、キーをシリンダ錠７に差し込んで、右に回すと、カム板８が同方向に回動し、カム板８の第二係合凸部８ｂがロック部材１０を内側に回動させて、その係止部１１ｂと連結杆６の係止部６ａとの係合を外し、その後、カム板８の第一係合凸部８ａが連結杆６の係合部６ｂに係合して連結杆６を上方に摺動させる。このとき、連結杆６の上への摺動により鉤部材４，５が解錠位置に傾動し解錠状態となり、解錠保持部材１５がコイルばね１７の付勢力に伴って回動し、その係止部１５ｂを支持板３の係止凹部３ｃに嵌入させ、連結杆６は解錠位置に保持される。
【００２８】
一方、図示しないガラス枠を解錠する場合は、シリンダ錠７に差し込んだキーを左に回し、カム板８を図４の時計方向に回転させると、カム板８の第二係合凸部８ｂがガラス枠用解錠杆１８の係合部１８ｂに係合し、これを下方へ摺動させる。このガラス枠用解錠杆１８の下移動によって、その作動部１８ａが図示しない金枠のガラス枠施錠具の解錠用レバーを押し下げ、ガラス枠は開放される。
【００２９】
このように、施錠状態では、鉤部材４，５を連結する連結杆６がロック部材１０によってロックされ、鉤部材４，５は連結杆６のロックによりロックされる構造のため、針金などを鉤部材４，５、連結杆６に引っ掛けても解錠側に動かすことはできず、シリンダ錠７の錠軸の回動によるカム板８を回動する以外に、つまりシリンダ錠７はキーを抜いた状態で錠軸がロックされ、カム板８は回動不可能であるから、シリンダ錠７と適正なキーを用いて解錠操作しない限り、鉤部材４，５を傾動または連結杆６を摺動することができず、針金などによる不正解除を確実に防止することができる。また、解錠したときは、解錠保持部材１５により鉤部材４，５、連結杆６が解錠位置に保持されるから、解錠して前面枠を開き、キーをシリンダ錠から抜いた状態でも、その解錠状態は保持され、前面枠を閉じるとき、解錠保持部材１５が本体枠側の当て部２４に当って、解錠保持が解除され、鉤部材４，５が施錠可能な状態となるから、前面枠を閉じれば、自動的に鉤部材４，５が受け金具２２，２３に係止され、施錠することができる。
【００３０】
【発明の効果】
以上説明したように、本発明のパチンコ機用施錠装置によれば、施錠状態では、鉤部材及びそれを連結する連結杆がロック部材によりロックされ、シリンダ錠によってカム板を回動する以外に、つまりシリンダ錠を用いて解錠操作をしない限り、鉤部材を傾動させることができず、針金などを連結杆または鉤部材に引っ掛けて行う不正解除を確実に防止することができる。また、シリンダ錠の操作によって解錠したとき、ロック部材のロック状態は解除されると共に、解錠保持部材によって連結杆と鉤部材が解除位置に保持され、前面枠を閉じたとき、解錠保持部材の解錠保持が解除され、施錠可能な状態となるので、従来の施錠装置と同様に、前面枠を閉じるだけで、自動的に施錠することができる。

Japanese Patent Laid-Open No. 11-206999
[Problems to be solved by the invention]
Although the pachinko machine locking device can satisfactorily lock the front frame of the pachinko machine, there is a problem that no countermeasure is taken against unauthorized unlocking using a wire or the like. In other words, in pachinko halls in recent years, the front frame and glass frame of pachinko machines have been illegally unlocked during operation, and ROMs that store game programs in the main body frame have been replaced with illegal ones. Incidents have been made in which fraudulent acts to illegally pay out Such unauthorized unlocking usually involves inserting a wire or wire from the gap between the main body frame and the front frame, hooking the locking rod of the locking device or the glass frame locking rod with the tip of the wire, and moving it in the unlocking direction Has been done. For this reason, there has been a demand for a locking device for a pachinko machine that can prevent unauthorized unlocking using a wire or the like.
[0006]
The present invention has been made to solve the above-described problems, and an object of the present invention is to provide a locking device for a pachinko machine that can prevent unauthorized unlocking using a wire or the like.
[0007]
[Means for Solving the Problems]
In order to achieve the above object, the locking device for a pachinko machine according to the present invention is such that the hook member is pivotally supported on the upper and lower parts of the vertically long base frame so that the connecting hook can slide inside the base frame. It is disposed and connected to the upper and lower ends of the connecting rod so that the flange member tilts by the vertical sliding of the connecting rod, and the cylinder lock is fixed to the mounting plate of the base frame so that the lock shaft is inserted inside, For pachinko machines where a cam plate that can be engaged with the connecting rod is fixed at the tip of the lock shaft, the connecting rod is slid through the cam plate by operating the cylinder lock, and the front frame is unlocked by tilting the rod member In the locking device, the base frame is provided with a locking member that locks the connecting rod when the connecting rod is in the locking position. The locking member has a locking portion that locks the locking portion of the connecting rod, and a cam. It has an engaging part that engages with the plate and is pivotally supported by the base frame so that the lock member is a cam. When rotated to unlocked side, it is configured to unlock upon unlocking by tilting the hook member by the operation of the cylinder lock, unlocking to hold the unlocked state of the connecting rod and the hook member A holding member is provided, and the unlocking holding member has a locking portion that can be locked in a locking recess provided in the base frame, is pivotally supported by a connecting rod, and the front frame is on the main body frame side. When it is closed, it is configured to rotate by hitting a part on the main body frame side to release the unlocked state.
[0009]
The lock member has an engaging portion that engages with an engaging convex portion of the cam plate when the cam plate is rotated to the unlocking side, and is locked by rotating the engaging convex portion of the cam plate. It can be set as the structure which a member rotates and releases the lock | rock of a connection rod.
[0010]
[Action]
In the locking device for a pachinko machine having such a configuration, when the key is inserted into the cylinder lock and the lock shaft is rotated, the cam plate is rotated, and at this time, the engagement convex portion of the cam plate moves the lock member, The engagement between the engaging portion and the engaging portion of the connecting rod is released, and then the engaging convex portion of the cam plate is engaged with the engaging portion of the connecting rod, and the connecting rod is slid. At this time, the hook member is tilted to the unlocking position by the sliding of the connecting rod, and the engagement with the receiving metal fitting on the main body frame side is released and unlocked. At the same time, the unlocking holding member fits the locking portion into the locking recess of the support plate, holds the connecting rod in the unlocked position, and holds the unlocked state.
[0011]
On the other hand, when the opened front frame is closed with respect to the main body frame, first, the unlocking holding member of the locking device hits part of the main body frame side, and the unlocking holding member uses the locking portion as the locking recess of the base frame. Since the unlocking is released, the connecting rod is slid to the locking side by the urging force of the coil spring, and the upper and lower flange members are in a lockable state. When it hits the receiving bracket on the side, it is locked there and is locked.
[0012]
In this locked state, the locking portion of the locking member is locked to the locking portion of the connecting rod, and the connecting rod is locked, so that the connecting rod is unlocked by means other than a key, such as a wire. Even if it tries to move, it does not move, and even if it tries to tilt the hook member toward the unlocking side, the connecting hook does not slide because it does not slide. Therefore, it is possible to prevent unauthorized unlocking by illegally inserting a wire or the like and hooking the tip of the wire member or connecting rod to move the tip to move it illegally.
[0013]

[0029]
Thus, in the locked state, the connecting rod 6 that connects the rod members 4 and 5 is locked by the lock member 10, and the rod members 4 and 5 are locked by the lock of the connecting rod 6. Even if it is hooked on the members 4 and 5 and the connecting rod 6, it cannot be moved to the unlocking side, and in addition to rotating the cam plate 8 by the rotation of the locking shaft of the cylinder lock 7, that is, the cylinder lock 7 removes the key. In this state, the lock shaft is locked and the cam plate 8 cannot be rotated. Therefore, unless the unlocking operation is performed using the cylinder lock 7 and an appropriate key, the flange members 4 and 5 are tilted or the connecting rod 6 is slid. It is impossible to move, and it is possible to reliably prevent unauthorized release by a wire or the like. When unlocked, the unlocking holding member 15 holds the flange members 4 and 5 and the connecting rod 6 in the unlocked position, so that the front frame is unlocked and the key is removed from the cylinder lock. However, the unlocked state is maintained, and when the front frame is closed, the unlocked holding member 15 hits the abutting portion 24 on the main body frame side, the unlocked holding is released, and the hook members 4 and 5 can be locked. Therefore, when the front frame is closed, the flange members 4 and 5 are automatically locked to the receiving brackets 22 and 23 and can be locked.
