Description

本発明は、パチンコ機の中枠（前面枠）に取り付けられ、中枠を本体枠に対し施錠し、且つ中枠に対し開閉可能に取り付けられたガラス枠を施錠するパチンコ機の施錠装置に関する。 The present invention relates to a locking device for a pachinko machine, which is attached to a middle frame (front frame) of a pachinko machine, locks the middle frame to a main body frame, and locks a glass frame attached to the middle frame so as to be opened and closed.

パチンコ機の中枠（前面枠）は、本体枠の前面に、ヒンジを介して開閉可能に装着され、さらに中枠の前面にガラス枠が開閉可能に装着される。このような中枠（前面枠）に取り付けられ、中枠を本体枠に対し施錠し、且つ中枠に対し開閉可能に取り付けられたガラス枠を施錠するパチンコ機の施錠装置として、上部と下部にフック状の係止爪を背面側に突設してなる中枠用施錠杆と、上部と下部にフック状の係止爪を正面側（シリンダ錠側）に突設してなるガラス枠用施錠杆とを、縦長の基枠体内に上下の摺動可能に配設した施錠装置が、下記特許文献１などにより知られている。 The middle frame (front frame) of the pachinko machine is mounted on the front surface of the main body frame so as to be opened and closed via a hinge, and further, the glass frame is mounted on the front surface of the middle frame so as to be opened and closed. As a locking device of a pachinko machine that is attached to such an inner frame (front frame), locks the inner frame to the main body frame, and locks the glass frame that can be opened and closed with respect to the inner frame, Locking rod for middle frame with hook-shaped locking claw protruding on the back side, and locking for glass frame with hook-shaped locking claw protruding on the front side (cylinder lock side) at the top and bottom A locking device in which a scissors is disposed in a vertically long base frame so as to be vertically slidable is known from Patent Document 1 below.

この施錠装置は、パチンコ機の本体枠に対し中枠を閉じると、中枠用施錠杆の係止爪が本体枠側に設けた受け金具に摺動しながら係止され、解錠する際は、基枠体の正面側に取り付けたシリンダ錠の錠軸のカム部材により、中枠用施錠杆を摺動させて係止爪と受け金具との係合を外して解錠する。一方、パチンコ機の中枠に対しガラス枠を閉じると、ガラス枠用施錠杆の係止爪がガラス枠側に設けた受け金具に摺動しながら係止され、それを解錠する場合は、シリンダ錠の錠軸のカム部材により、ガラス枠用施錠杆を摺動させて係止爪と受け金具との係合を外して解錠する。 When this locking device closes the middle frame with respect to the main body frame of the pachinko machine, the locking claw of the locking frame for the middle frame is locked while sliding on the metal fitting provided on the main body frame side, and when unlocking Then, the lock member for the middle frame is slid by the cam member of the lock shaft of the cylinder lock attached to the front side of the base frame body, and the engagement between the locking claw and the receiving metal is released and unlocked. On the other hand, when the glass frame is closed with respect to the inner frame of the pachinko machine, the locking claw of the locking rod for the glass frame is locked while sliding on the metal fitting provided on the glass frame side, and when unlocking it, The lock member for the glass frame is slid by the cam member of the lock shaft of the cylinder lock, and the engagement between the locking claw and the receiving metal is released and unlocked.

このような構造の施錠装置では、ガラス枠または中枠を閉じたとき、ガラス枠用施錠杆または中枠用施錠杆が自動的に（係止爪が受け金具に接触して受ける反力により）摺動して施錠される構造のため、施錠が完了状態においても、ガラス枠用施錠杆または中枠用施錠杆が摺動可能な状態となる。このため、施錠状態において、パチンコ機の中枠の隙間から針金等の不正器具を挿入して、その先端を係止爪に引っ掛けてガラス枠用施錠杆または中枠用施錠杆を解錠方向に摺動させた場合、不正解錠が可能となる虞があった。
特開２００５−２９６４０３号公報特開２００７−３１３０４９号公報 In the locking device having such a structure, when the glass frame or the inner frame is closed, the glass frame locking rod or the inner frame locking rod is automatically (by the reaction force received by the locking claw contacting the receiving metal). Because of the structure that is locked by sliding, the glass frame locking rod or the middle frame locking rod is slidable even when the locking is completed. For this reason, in the locked state, a fraudulent instrument such as a wire is inserted through the gap in the middle frame of the pachinko machine, and its tip is hooked on the locking claw so that the glass frame locking rod or the middle frame locking rod is in the unlocking direction. When sliding, there is a possibility that unauthorized unlocking may be possible.
JP 2005-296403 A JP 2007-313049 A

このために、従来、施錠状態で、中枠用施錠杆またはガラス枠施錠杆が不正に解錠方向に移動力を受けたとき、カム部材用の係合部をカム部材の係合凸部に当接させて、中枠用施錠杆またはガラス枠施錠杆の移動を阻止するようにロックして不正解錠を防止する施錠装置が、上記特許文献２などで提案されている。この施錠装置のカムロック機構は、シリンダ錠の錠軸に固定されるカム部材の係合凸部を長めに形成し、中枠用施錠杆及びガラス枠施錠杆に設けられたカム部材用の係合孔にその係合凸部を、施錠時には嵌入した状態とし、カム部材により中枠用施錠杆及びガラス枠施錠杆の移動をロックするように構成される。 Therefore, conventionally, when the locking frame for the inner frame or the locking frame for the glass frame is improperly moved in the unlocking direction in the locked state, the engaging portion for the cam member becomes the engaging convex portion of the cam member. Patent Document 2 and the like have proposed a locking device that is brought into contact with and locked so as to prevent movement of the inner frame locking rod or the glass frame locking rod to prevent unauthorized unlocking. The cam lock mechanism of the locking device is formed with a long engagement protrusion of the cam member fixed to the lock shaft of the cylinder lock, and the engagement for the cam member provided on the locking frame for the middle frame and the locking frame for the glass frame. The engaging convex portion is fitted in the hole during locking, and the cam member is configured to lock the movement of the middle frame locking rod and the glass frame locking rod.

しかし、この種のカムロック方式の施錠装置は、中枠またはガラス枠が開放された状態においても、常時、カム部材の係合凸部が中枠用施錠杆及びガラス枠施錠杆の係合孔に嵌合しているため、中枠またはガラス枠を閉じることにより、自動的に中枠用施錠杆またはガラス枠施錠杆を摺動させて施錠しようとしても、キーをシリンダ錠から抜いた状態では、カム部材の回動がロックされた状態にあるため、中枠またはガラス枠を閉じて施錠することができず、使用状況によっては使用しにくいという問題があった。つまり、開放された状態の中枠またはガラス枠を閉じて自動的に施錠する際には必ずキーをシリンダ錠に差し込んだ状態とする必要があり、キーを抜いた状態で中枠またはガラス枠を閉じると、施錠装置の施錠動作が不完全となり、故障の原因となるなどの問題があった。 However, in this type of cam lock type locking device, even when the middle frame or the glass frame is opened, the engaging projections of the cam member are always in the engagement holes of the middle frame locking rod and the glass frame locking rod. Because it is fitted, by closing the middle frame or glass frame, even if you try to automatically lock the middle frame locking rod or glass frame locking rod by sliding, the key is removed from the cylinder lock, Since the rotation of the cam member is locked, the inner frame or the glass frame cannot be closed and locked, and it is difficult to use depending on the use situation. In other words, when closing the open middle frame or glass frame and automatically locking it, the key must be inserted into the cylinder lock. When closed, there is a problem that the locking operation of the locking device becomes incomplete and causes a failure.

さらに、従来、施錠状態の中枠用施錠杆の移動をロックするパチンコ機の施錠装置として、基枠体にロック部材を揺動可能に枢支し、このロック部材により、施錠状態における中枠用施錠杆をロックして不正解錠を防止する施錠装置が知られている。この施錠装置は、施錠状態における中枠用施錠杆にロック部材を係止させてそれをロックし、シリンダ錠による解錠の際には、カム部材の回動によりロック部材のロックを解除すると共に、中枠用施錠杆を摺動させて解錠する。 Further, conventionally, as a locking device for a pachinko machine that locks the movement of the locking rod for the middle frame in the locked state, a locking member is pivotally supported on the base frame body, and this locking member is used for the middle frame in the locked state. There is known a locking device that locks a locking rod to prevent unauthorized unlocking. The locking device locks the locking member by locking the locking member for the middle frame in the locked state, and unlocks the locking member by rotating the cam member when unlocking with the cylinder lock. Then, slide the middle frame locking rod to unlock.

しかし、このパチンコ機の施錠装置は、施錠状態における中枠用施錠杆をロックすることはできるものの、ガラス枠用施錠杆についてはロックすることができず、施錠状態における中枠用施錠杆とガラス枠用施錠杆の両方をロックする機構を備えたパチンコ機の施錠装置の開発が望まれていた。 However, the locking device of this pachinko machine can lock the locking frame for the inner frame in the locked state, but cannot lock the locking rod for the glass frame, and the locking frame for the inner frame and the glass in the locked state. Development of a locking device for a pachinko machine equipped with a mechanism for locking both the frame locking rods has been desired.

本発明は、上記の課題を解決するために、施錠状態で中枠施錠杆とガラス枠施錠杆の両方をロックして、針金などの不正器具による不正解錠を防止することができるパチンコ機の施錠装置を提供することを目的とする。 In order to solve the above-described problems, the present invention provides a pachinko machine that can lock both the middle frame locking rod and the glass frame locking rod in a locked state and prevent unauthorized unlocking by an unauthorized instrument such as a wire.

そのような施錠状態において、キー操作によりシリンダ錠９の錠軸９ａと共にカム部材１０が回動し、先ずロック解除部材４が下方に摺動したとき、ガラス枠ロック受け部材８を僅かに後方に揺動させて、ガラス枠ロック部材７の係合凸部７２とガラス枠ロック受け部材８の係合部８１の係合を外し、ガラス枠施錠杆３のロックを解除する。そして、これに続くカム部材１０の回動により、ガラス枠施錠杆３は解錠側（下方）に摺動し、解錠動作が行なわれるようになっている。 In such a locked state, the cam member 10 is rotated together with the lock shaft 9a of the cylinder lock 9 by the key operation, and when the unlocking member 4 first slides downward, the glass frame lock receiving member 8 is slightly moved backward. By swinging, the engagement projection 72 of the glass frame lock member 7 and the engagement portion 81 of the glass frame lock receiving member 8 are disengaged, and the lock of the glass frame locking rod 3 is released. Then, by the subsequent rotation of the cam member 10, the glass frame locking rod 3 slides to the unlocking side (downward), and the unlocking operation is performed.

このように構成された施錠装置は、図１２に示すように、基枠体１が、パチンコ機における中枠９１の自由端側の右端に縦に、且つ鉤部２１，２２を本体枠９０側に向けた状態で装着される。一方、本体枠９０の右側壁部の内側における上記鉤部２１，２２に対応した上下位置に、受け部９３が固定され、この受け部９３に鉤部２１，２２が係止される。また、本体枠９０側には、中枠ロック部材５の突出部５１が当接する当接部９４が設けられる。 As shown in FIG. 12, the locking device configured as described above has the base frame 1 vertically on the right end on the free end side of the middle frame 91 in the pachinko machine, and the collars 21 and 22 on the main body frame 90 side. It is mounted in the state of facing. On the other hand, the receiving portion 93 is fixed to the upper and lower positions corresponding to the flange portions 21 and 22 inside the right side wall portion of the main body frame 90, and the flange portions 21 and 22 are locked to the receiving portion 93. Further, on the main body frame 90 side, a contact portion 94 with which the protruding portion 51 of the middle frame lock member 5 contacts is provided.

一方、中枠９１の前面にガラス枠（遊技盤を覆う透明板を装着した前扉）９２が開閉可能に取り付けられる。そのガラス枠９２の右端自由端側の内側に、ガラス枠施錠杆３の鉤部３１、３２、３３が係止される受け部９５，９５，９５が、各々対応した箇所に設けられる。なお、中間位置の受け部９５は、ガラス枠ロック部材７の突出部７１の当接部として兼用される。 On the other hand, a glass frame (front door equipped with a transparent plate covering the game board) 92 is attached to the front surface of the middle frame 91 so as to be opened and closed. Receiving portions 95, 95, 95 to which the flange portions 31, 32, 33 of the glass frame locking rod 3 are locked are provided at corresponding positions on the inner side of the right end of the glass frame 92. Note that the receiving portion 95 at the intermediate position is also used as a contact portion of the protruding portion 71 of the glass frame locking member 7.

上記構成の施錠装置は、上記の如く、パチンコ機の中枠９１の右端自由端側に縦に固定されて使用されるが、施錠機構の主要部となる中枠施錠杆２、ガラス枠施錠杆３は基枠体１の支持板１２の左側面に装着され、中枠９１の自由端側に対して支持板１２が壁となる。また、支持板１２及び背面板１３に設けた開口部１２ａ及びカム室１４は支持板１２の右側面からカバー１８で覆われている。このため、施錠した状態で、本体枠９０と中枠９１の右端自由端側の隙間、或いは中枠９１とガラス枠９２の右端自由端側の隙間などから、不正解錠を狙って針金などの不正器具を差し込まれたとしても、基枠体１の支持板１２、カバー１８などが壁となって、不正器具が中枠施錠杆２、ガラス枠施錠杆３、ロック解除部材４などに到達せず、不正解錠を防止することができる。 As described above, the locking device having the above configuration is used by being vertically fixed to the right end free end side of the middle frame 91 of the pachinko machine, but the middle frame locking rod 2 and the glass frame locking rod which are the main parts of the locking mechanism. 3 is mounted on the left side surface of the support plate 12 of the base frame 1, and the support plate 12 serves as a wall with respect to the free end side of the middle frame 91. The opening 12 a and the cam chamber 14 provided in the support plate 12 and the back plate 13 are covered with a cover 18 from the right side surface of the support plate 12. For this reason, in the locked state, from the gap on the right end free end side of the main body frame 90 and the middle frame 91 or the gap on the right end free end side of the middle frame 91 and the glass frame 92, etc. Even if an unauthorized device is inserted, the support plate 12 and the cover 18 of the base frame 1 become walls, and the unauthorized device cannot reach the middle frame locking rod 2, the glass frame locking rod 3, the unlocking member 4, and the like. Therefore, unauthorized unlocking can be prevented.

パチンコ機の中枠９１が開放された状態において、中枠９１を本体枠９０に対し閉じると、本体枠９０側の受け部９３が鉤部２１，２２に接触し、これにより中枠施錠杆２が上側の荷重を受けて上昇した後、ばね部材１７の付勢力により下降し、鉤部２１，２２が受け部９３に係止され施錠状態となる。 When the middle frame 91 is closed with respect to the main body frame 90 in a state in which the middle frame 91 of the pachinko machine is opened, the receiving portion 93 on the main body frame 90 side comes into contact with the collar portions 21 and 22, thereby the middle frame locking rod 2. After being lifted by receiving the upper load, the spring member 17 is lowered by the urging force of the spring member 17, and the flange portions 21 and 22 are locked to the receiving portion 93 to be locked.

このとき、中枠ロック部材５の突出部５１が本体枠９０側の当接部９４に当接して内側に揺動し、これにより図１５（ｂ）のように、その係合凸部５２が中枠ロック受け部材６の係合部６１に係合した状態となり、中枠施錠杆２は中枠ロック部材５と中枠ロック受け部材６を介して上下動がロックされる。したがって、中枠施錠杆２は、シリンダ錠９による解錠操作を除き、解錠方向に摺動することができず、針金などの不正器具による不正解錠は阻止されることとなる。 At this time, the protruding portion 51 of the middle frame locking member 5 abuts on the abutting portion 94 on the main body frame 90 side and swings inward, so that the engaging convex portion 52 is moved as shown in FIG. The middle frame lock receiving member 6 is engaged with the engaging portion 61, and the middle frame locking rod 2 is locked up and down via the middle frame lock member 5 and the middle frame lock receiving member 6. Therefore, except for the unlocking operation by the cylinder lock 9, the middle frame locking rod 2 cannot slide in the unlocking direction, and unauthorized unlocking by an unauthorized instrument such as a wire is prevented.

一方、パチンコ機のガラス枠９２が開放された状態において、ガラス枠９２を中枠９１に対し閉じると、中枠９１側の受け部９５が鉤部３１，３２，３３に接触し、これによりガラス枠施錠杆３が下側の荷重を受けて下降した後、ばね部材１７の付勢力により上昇し、鉤部３１，３２，３３が受け部９５に係止され施錠状態となる。 On the other hand, when the glass frame 92 of the pachinko machine is opened, when the glass frame 92 is closed with respect to the middle frame 91, the receiving portion 95 on the side of the middle frame 91 comes into contact with the flange portions 31, 32, 33. After the frame locking rod 3 is lowered by receiving the lower load, the frame locking rod 3 is lifted by the urging force of the spring member 17, and the flange portions 31, 32, 33 are locked to the receiving portion 95 to be locked.

このとき、ガラス枠ロック部材７の突出部７１が中枠９１側の受け部９５に当接して内側に揺動し、これにより図１６（ｂ）のように、その係合凸部７２がガラス枠ロック受け部材８の係合部８１に係合した状態となり、ガラス枠施錠杆３はガラス枠ロック部材７とガラス枠ロック受け部材８を介して上下動がロックされる。したがって、ガラス枠施錠杆３は、シリンダ錠９による解錠操作を除き、解錠方向に摺動することができず、針金などの不正器具による不正解錠は阻止されることとなる。 At this time, the protruding portion 71 of the glass frame locking member 7 abuts on the receiving portion 95 on the side of the middle frame 91 and swings inward, so that the engaging convex portion 72 is made of glass as shown in FIG. The glass frame locking rod 3 is engaged with the engaging portion 81 of the frame lock receiving member 8, and the vertical movement of the glass frame locking rod 3 is locked via the glass frame locking member 7 and the glass frame lock receiving member 8. Therefore, the glass frame locking bar 3 cannot slide in the unlocking direction except for the unlocking operation by the cylinder lock 9, and unauthorized unlocking by an unauthorized instrument such as a wire is prevented.

中枠９１を解錠する場合、シリンダ錠９に挿入したキーを右に回す。これにより、カム部材１０が図１５（ａ）の矢印方向（反時計方向）に回動し、カム部材１０の第１係合凸部１０ａが、まずロック解除部材４の第１係合部４１に係合して、図１５（ａ）のように、ロック解除部材４を押し上げる。これにより、図１５（ｂ）に示すように、ロック解除部材４の中枠係合部４３が中枠ロック受け部材６の係合凸部６２に係合して中枠ロック受け部材６を僅かに上方に押し上げるように、図１５（ｂ）の反時計方向に中枠ロック受け部材６を僅かに回動させる。これにより、中枠ロック部材５の係合凸部５２と中枠ロック受け部材６の係合部６１の係合が外れ、ロックが解除され、中枠施錠杆２は上昇可能となる。 When unlocking the middle frame 91, the key inserted into the cylinder lock 9 is turned clockwise. As a result, the cam member 10 rotates in the direction of the arrow (counterclockwise) in FIG. 15A, and the first engagement convex portion 10 a of the cam member 10 firstly has the first engagement portion 41 of the lock release member 4. And the unlocking member 4 is pushed up as shown in FIG. As a result, as shown in FIG. 15B, the middle frame engaging portion 43 of the lock release member 4 engages with the engaging convex portion 62 of the middle frame lock receiving member 6 so that the middle frame lock receiving member 6 is slightly moved. The middle frame lock receiving member 6 is slightly rotated counterclockwise as shown in FIG. Thereby, the engagement convex part 52 of the middle frame lock member 5 and the engagement part 61 of the middle frame lock receiving member 6 are disengaged, the lock is released, and the middle frame locking rod 2 can be raised.

この後、カム部材１０の第１係合凸部１０ａが上記と同方向にさらに回動すると、第１係合凸部１０ａが中枠施錠杆２の係合部２３に係合して、中枠施錠杆２が第１係合凸部１０ａにより押し上げられる。このとき、図１３に示すように、中枠施錠杆２はばね部材１７の付勢力に抗して上方に摺動し、その鉤部２１，２２が上昇して、本体枠９０側の受け部９３から離れ、解錠される。 Thereafter, when the first engaging convex portion 10a of the cam member 10 further rotates in the same direction as described above, the first engaging convex portion 10a engages with the engaging portion 23 of the middle frame locking rod 2, and The frame locking rod 2 is pushed up by the first engaging convex portion 10a. At this time, as shown in FIG. 13, the middle frame locking rod 2 slides upward against the urging force of the spring member 17, and the collar portions 21 and 22 are lifted to receive the receiving portion on the main body frame 90 side. It moves away from 93 and is unlocked.

一方、ガラス枠９２を解錠する場合は、キーをシリンダ錠９に差し込み、左に回すと、カム部材１０が図１６（ａ）の矢印方向（時計方向）に回動し、カム部材１０の第２係合凸部１０ｂは、先ず、ロック解除部材４の第２係合部４２に係合して、図１６（ａ）のように、ロック解除部材４を押し下げる。これにより、図１６（ｂ）に示すように、ロック解除部材４のガラス枠係合部４４がガラス枠ロック受け部材８の係合凸部８２に係合してガラス枠ロック受け部材８を僅かに下方に押し下げるように、図１６（ｂ）の反時計方向にガラス枠ロック受け部材８を僅かに回動させる。これにより、ガラス枠ロック部材７の係合凸部７２とガラス枠ロック受け部材８の係合部８１の係合が外れ、ロックが解除され、ガラス枠施錠杆３は下降可能となる。 On the other hand, when unlocking the glass frame 92, when the key is inserted into the cylinder lock 9 and turned counterclockwise, the cam member 10 rotates in the direction of the arrow (clockwise) in FIG. First, the second engaging convex portion 10b engages with the second engaging portion 42 of the unlocking member 4 and pushes down the unlocking member 4 as shown in FIG. As a result, as shown in FIG. 16B, the glass frame engaging portion 44 of the unlocking member 4 engages with the engaging convex portion 82 of the glass frame lock receiving member 8, and the glass frame lock receiving member 8 is slightly moved. The glass frame lock receiving member 8 is slightly rotated in the counterclockwise direction of FIG. Thereby, the engagement convex part 72 of the glass frame lock member 7 and the engagement part 81 of the glass frame lock receiving member 8 are disengaged, the lock is released, and the glass frame locking rod 3 can be lowered.

この後、カム部材１０の第２係合凸部１０ｂが上記と同方向にさらに回動すると、第２係合凸部１０ｂがガラス枠施錠杆３の係合部３５に係合して、ガラス枠施錠杆３が第２係合凸部１０ｂにより押し下げられる。このとき、図１４に示すように、ガラス枠施錠杆３はばね部材１７の付勢力に抗して下方に摺動し、その鉤部３１，３２，３３が下降して、中枠９１側の受け部９５から離れ、解錠される。 Thereafter, when the second engaging convex portion 10b of the cam member 10 is further rotated in the same direction as described above, the second engaging convex portion 10b is engaged with the engaging portion 35 of the glass frame locking rod 3, and the glass The frame locking rod 3 is pushed down by the second engagement convex portion 10b. At this time, as shown in FIG. 14, the glass frame locking rod 3 slides downward against the urging force of the spring member 17, and the collar portions 31, 32, 33 are lowered to move toward the middle frame 91 side. It leaves the receiving part 95 and is unlocked.

このように、ガラス枠９２を中枠９１に対し良好に施錠・解錠を行うことができると共に、中枠９１を本体枠９０に対し良好に施錠・解錠することができ、ガラス枠９２及び中枠９１の施錠状態においては、ガラス枠ロック部材７、ガラスロック受け部材８の作用によって、ガラス枠施錠杆３の解錠側への摺動がロックされ、且つ中枠ロック部材５、中枠ロック受け部材６の作用によって、中枠施錠杆２の解錠側への摺動がロックされるので、針金などの不正器具によりガラス枠施錠杆３または中枠施錠杆２を解錠側へ摺動させて行なわれる不正解錠を防止することができる。 As described above, the glass frame 92 can be locked and unlocked with respect to the middle frame 91, and the middle frame 91 can be locked and unlocked with respect to the main body frame 90. In the locked state of the middle frame 91, sliding of the glass frame locking rod 3 to the unlocking side is locked by the action of the glass frame locking member 7 and the glass lock receiving member 8, and the middle frame locking member 5 and middle frame are locked. Since the sliding of the middle frame locking rod 2 to the unlocking side is locked by the action of the lock receiving member 6, the glass frame locking rod 3 or the middle frame locking rod 2 is slid to the unlocking side by an unauthorized instrument such as a wire. It is possible to prevent unauthorized unlocking performed.
