Description

  The present invention relates to a locking device for a game machine that locks a front frame (front door) of a game machine such as a pachinko machine or a slot machine to a main body frame (cabinet).

  Conventionally, as a locking device for a pachinko machine, generally, an operating rod is slidably disposed inside a base frame body, and a hook member is connected to the upper and lower portions of the support plate of the base frame body so as to tilt. It is pivotally supported, and the cylinder lock is fixed to the middle part of the mounting plate of the base frame body so that the lock shaft is inserted inward from the hole provided in the mounting plate, and is engaged with the operating rod at the tip of the lock shaft. A locking device having a configuration in which a cam member is attached is used.

  Although this type of game machine locking device has a strong structure and can perform locking and unlocking operations with certainty, the locking device collar attached to the inside of the front frame is the inner side of the front frame. Protrude from. For this reason, when the assembly of the front frame is packed and transported, the packaging is difficult, and there is a problem that the protruding collar member hits other parts during transportation and is damaged.

Therefore, the present inventors have conventionally proposed a locking device for a pachinko machine that does not have a portion protruding from the inside of the front frame and can lock and unlock the front frame with respect to the main body frame smoothly and reliably ( (See Patent Document 1 below).
Japanese Patent No. 3087024

  In this locking device, a long operating rod is slidably disposed inside a base frame body having a mounting plate bent in an L-shaped section and a support plate, and a cylinder lock is fixed to an intermediate portion of the mounting plate. A locking device in which the cam member is attached to the lock shaft of the cylinder lock so as to be engageable with the operating rod, the mounting plate of the base frame body is attached to the inside of the front frame, and the receiving metal fitting is attached to the inside of the main body frame, Openings that allow the brackets to enter are formed in the upper and lower portions of the support plate of the base frame body, and latch members having lock recesses that restrain the brackets in the openings are respectively rotated in the vicinity of the upper and lower openings. It is pivotally supported, and engaging pins are attached to the upper and lower parts of the operating rod. When the upper and lower latch members are pushed by the receiving bracket and rotated to the latched position, the engaging pin of the operating rod is engaged. The engagement part for locking in the latch position together is part of the latch member It is formed, and a coil spring for biasing the operating rod to the locked side to urge the latch member to the unlocking side is hung on actuation plates and the latch member.

  By the way, this type of locking device performs the unlocking operation by sliding the operating rod by the key operation of the cylinder lock. In the locked state, the wire is improperly inserted into the gap of the front frame and hooked on the operating rod. When sliding, the operating rod may move in the unlocking direction, and unauthorized unlocking may be performed. For this reason, in the locked state other than during the unlocking operation by the cylinder lock, the cam member fixed to the lock shaft of the cylinder lock is engaged with the operating rod to prevent the sliding of the operating rod in the unlocking direction. A structure to prevent unauthorized unlocking was studied.

  However, in a locked state other than during the unlocking operation with the cylinder lock, the cam member fixed to the lock shaft of the cylinder lock and the operating rod are engaged to prevent the sliding of the operating rod in the unlocking direction. In this case, there is a problem that the range of use of the locking device in the pachinko hall is limited.

  In other words, when a pachinko machine equipped with this type of locking device is used by being carried into a pachinko hall, an electric unlocking mechanism may be added to the locking device on the hall side. The electric drive mechanism such as an electromagnetic solenoid is connected to the operating rod and is configured to be unlocked by electrically sliding the operating rod. Since it will be in the state which prevents sliding, it becomes impossible to mount | wear with such an electric unlocking mechanism.

  For this reason, in an unlocked state other than during the unlocking operation by the cylinder lock, the cam member fixed to the lock shaft of the cylinder lock is engaged with the operating rod to prevent the unlocking from sliding in the unlocking direction. There has been a demand for a locking device having a lock prevention function and a structure capable of stopping the unauthorized unlocking prevention function as desired by the user.

  The present invention has been made in view of the above points, and prevents unauthorized unlocking by sliding an operating rod with a wire or the like, and cancels the unauthorized unlocking function as desired by a user. An object of the present invention is to provide a locking device for a game machine.

In order to achieve the above object, a locking device for a game machine according to claim 1 of the present invention is long along a support plate of a base frame having a mounting plate and a support plate bent in a substantially L-shaped cross section. An operating rod is slidably disposed, a cylinder lock is fixed to the mounting plate, a cam member is attached to the locking shaft of the cylinder lock so as to be engageable with the operating rod, and the mounting plate of the base frame body In the locking device of the game machine, which is attached to the inside of the front frame of the game machine and the metal fitting is attached to the inside of the main body frame of the game machine,
An opening for allowing the receiving metal fitting to enter is formed in the support plate of the base frame body, and a latch member having a lock recess for restraining the receiving metal in the opening is pivotally supported in the vicinity of the opening. The latch member is provided with a locking pin protruding so as to be movable toward the support plate. The support plate is provided with a guide locking hole for engaging the locking pin. An operation engaging portion is provided for engaging with the locking pin of the latch member at the time of unlocking and moving in the unlocking direction, and when the latch member is pushed by the receiving metal and rotated to the latch position, The latch pin of the latch member engages with the lock portion of the guide latch hole of the support plate, and the latch member is held in the latch position.
The latch member includes a spring member for holding the locking pin movably and biasing the locking pin toward the locking side and biasing the latch member itself toward the unlocking side. ,
A cam lock member that engages with an engaging convex portion of the cam member in a locked state to prevent the operating rod from sliding is attached to the position corresponding to the cam member in the operating rod in a switchable manner. The switching operation of the cam member engages the engaging convex portion of the cam member to prevent the operating rod from sliding, and the engaging convex portion of the cam member does not engage the operating rod. It is characterized in that it is possible to switch between a state in which sliding is permitted.

  Here, the cam lock member is formed in a substantially S-shape, and a central portion thereof is pivotally supported via a pivot shaft with respect to the operating rod, and both inner sides of the cam lock member are engaged with the cam member. It can be configured to engage the mating convex portion to prevent the operating rod from sliding.

  In addition, the cam lock member is formed in a plate shape having an opening, and a cam abutting portion that abuts the engaging convex portion of the cam member at the edge of the opening to prevent the operating rod from sliding. The cam lock member is formed to be bent inward, and the cam lock member can be configured to slide between a fixed position with respect to the operating rod and to switch between sliding and blocking of the operating rod.

  In addition, a curled bent portion is formed by bending the edge of the metal plate into a curled shape at the engaging portion of the receiving metal fitting, and when the lock is locked, the curled bent portion enters the opening to lock the locking recess of the latch member. It can be configured to be constrained within.

  In the locking device configured as described above, when the front frame is closed with respect to the main body frame, the receiving member enters the lock recess of the latch member from the opening of the support plate, and the latch member rotates so that the receiving member pushes the latch member. It moves and it will be in the state where the receiving metal fitting was restrained in the lock crevice of a latch member. At this time, since the latch pin of the latch member enters and is locked into the lock portion of the guide latch hole on the support plate side, the latch member is held at the latch position, and the receiving metal fitting is inside the lock recess of the latch member. Locked to the locked state.

  On the other hand, in such a locked state, when the cam lock member is set and switched to a position where the unauthorized unlocking prevention function is generated, the operating rod is prevented from moving in the unlocking direction by the cam member. Even if an unauthorized device such as a wire is inserted through the gap to perform unauthorized unlocking, the operating rod does not move, and unauthorized unlocking can be prevented. On the other hand, for example, when an electric unlocking mechanism is mounted on the locking device and the operating rod is electrically moved to unlock the locking device, the cam lock member is switched to the sliding allowable side, and the engagement protrusion of the cam member is The operating rod is allowed to slide without being engaged with the operating rod. Accordingly, it is possible to use an electric unlocking mechanism that unlocks the operating rod in the unlocking direction by the electric mechanism.

  Also, the edge of the metal plate is bent into a curl shape on the metal fitting to form a curled bent portion, and this curled bent portion is inserted into the lock recess of the latch member and locked during locking. If this is the case, the angle of the curled bent portion with respect to the mounting portion can be adjusted, which makes it easier to adjust the angle of the curled bent portion than when a shaft pin is used for the receiving bracket, Can be easily adjusted. Furthermore, the receiving metal fitting can be manufactured with fewer processes by cutting and bending only the metal plate, and the curled bent portion can be smoothly entered into the lock recess and locked at the time of locking.
