Description

  The present invention relates to a locking device for a game machine that locks a front door of a game machine such as a slot machine to a housing, and more particularly, to a locking device for a game machine that can close the front door without gaps and lock it without rattling.

  Conventionally, as a locking device for a gaming machine such as a slot machine, 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. The cylinder lock is pivotally supported so that it can be tilted, and the cylinder lock is fixed to the middle part of the mounting plate of the base frame so that the lock shaft is inserted inward from the hole provided in the mounting plate. 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 game machine that does not have a portion protruding from the inside of the front frame and that can smoothly and reliably lock and unlock the front frame with respect to the main body frame ( (See Patent Document 1 below).

JP 2004-105417 A

  In this locking device, a long operating rod is slidably disposed inside a base frame body having a mounting plate and a support plate, and a cylinder lock is fixed to an intermediate portion of the mounting plate. The cam member is attached to the operating rod so as to be engageable, the attachment plate of the base frame body is attached to the inner side of the front frame, and the receiving member is attached to the inner side of the main body frame. Opening recesses are formed in the upper and lower portions of the support plate of the base frame body to allow the receiver to enter, and a substantially semicircular latch member having a groove-like latch recess for restraining the receiving member in the opening recess is formed on the upper part. Each is pivotally supported in the vicinity of the lower opening recess.

  A locking pin is movably attached to the latch member, and a guide locking hole is formed with a lock portion that is engaged with and guided by the tip of the locking pin on the support plate. An actuating engagement portion that operates to engage with the latch pin of the latch member and release the lock by the lock portion is provided, and a spring member that urges the latch member toward the unlocking side is incorporated.

  In this locking device, when the front frame is closed and the locking operation is performed, the latching portion of the receiving member is inserted into the latch recesses of the upper and lower latch members, and the latch member is pushed to the latch position. When the latch member is rotated to the lock position, the latch pin of the latch member moves from the guide latch hole to the lock portion, and the latch member is locked at the latch position and locked. On the other hand, at the time of unlocking, when the operating rod moves through the cam member by operating the cylinder lock, the operating engagement portion of the operating rod operates to unlock the latch member by the lock portion, and the latch member is attached to the spring member. It is turned to the unlocking side by the force and unlocked.

  By the way, a locking device is usually manufactured by assembling many metal plate parts and synthetic resin parts. However, each part has an error within a dimensional tolerance, that is, a variation in dimensions. An error within tolerance is also generated in the mounting position of the front door to which the device is mounted or the mounting position of the receiving device on the housing side to which the receiving device is mounted.

  For this reason, when the locking device is attached to a game machine and used, the front door is closed with respect to the housing due to a dimensional error of the receiving member or the latch member, an error of the mounting position, a dimensional error of the housing or the front door, etc. When the latch member is engaged and locked with the receiving member and the latch member is rotated to the latch position and is locked, the front door is not completely closed, and there is a slight rattling or the front door and the housing. There was a problem of generating gaps between the bodies.

And the operating rod 4 is pushed down, thereby lowering the sliding locking member 13 in the upper and lower latch units 10 via the engaging portion 4a. At this time, the latch unit 10 in the locked state as shown in FIG. 12 is unlocked by the lowering of the sliding locking member 13, and the spring force of the spring member 12 counterclockwise in FIG. It will rotate and perform the unlocking operation.

  As shown in FIG. 3, the right side surface of the base frame body 1 is covered and hidden by the support plate 3 so that the latch unit 10 and the operating rod 4 are not exposed. Thus, the latch unit 10 and the operating rod 4 are exposed on the left side surface of the base frame 1. For this reason, in order to cover the latch unit 10 and the operating rod 4 and prevent exposure, as shown in FIGS. 7 to 11, the first inside the support plate 3 of the base frame body 1 (the left side surface of the locking device). A cover 9 is attached so as to cover the upper and lower latch units 10 and the operating rod 4.

  The first cover 9 is formed in a vertically long rectangular shape and fixed with fixing screws, and corresponds to the upper and lower positions of the first cover 9 corresponding to the latch member 5 of the upper and lower latch units 10 and the opening 3 a of the support plate 3. Thus, when the opening 9a is provided and the front door 41 is closed, the locking portion 43 of the receiving member 42 enters the openings 3a and 9a and is locked. Further, as described above, the second cover 19 is attached to the cylinder mounting portion 17 so as to cover the lock shaft 7a of the cylinder lock 7 and the cam member 8 on the inside thereof, as shown in FIG. Mounted on the back side.

  As described above, the latch member 5, the operating rod 4, and the spring members 12 and 15, which are the main parts of the locking device, are substantially formed inside the support plate 3 of the base frame 1 by the first cover 9 and the second cover 19. The right side surface of the base frame body 1 that is completely covered and close to the gap on the right side of the front door 41 is covered with the support plate 3. For this reason, even when an unauthorized tool such as a wire is inserted through the gap on the right side of the front door 41 when using a game machine equipped with a locking device, the unauthorized tool does not reach the main part of the locking device, It is possible to prevent an illegal act performed by being inserted, and a locking device with high security performance can be obtained.

  Next, the usage mode and operation of the locking device of the game machine having the above configuration will be described. As shown in FIGS. 15 and 17, the locking device is vertically fixed to the free end side (right side toward the inside) of the front door 41 of the game machine via the mounting plate 2, and is opposed to the inside of the housing 40. A vertically long receiving tool 42 is attached to the position (the inner surface of the right side wall).

  As shown in FIGS. 15 and 16, the receiving member 42 has a planar U-shaped bearing portion fixed to the upper and lower portions of the belt-like mounting plate, and a shaft pin-like locking portion 43 is fixed to the bearing portion. Are constructed in a horizontal and horizontal direction. Further, a sliding plate 45 is horizontally attached to the receiver 42 at a position corresponding to the support roller 16 below the locking portion 43, and such a receiver 42 is attached to the inner wall surface of the housing 40. Fixed vertically. The locking device is attached vertically inside the front door 41, and is attached so that the keyhole of the cylinder lock 7 is exposed on the front surface of the front door 41.

  When the front door 41 is closed with respect to the housing 40 of the game machine, as shown in FIGS. 15 and 16, the locking device 43 moves relative to the receiver 42, so that the locking portion 43 is relatively opened. As shown in FIG. 18, the engaging portion 43 enters the lock recess 6 of the latch member 5 and pushes the latch member 5. At this time, the latch member 5 rotates in the clockwise direction of FIG. 18 against the urging force of the spring member 12, and the convex arc portion 5 a at the lower portion of the latch member 5 is the concave arc portion of the sliding engagement member 13. After sliding on 13a and rotating, the latch tooth portion 5b and the locking tooth portion 13b are engaged.

  That is, in the initial state of starting the closing of the front door 41, the convex arc portion 5a slides on the concave arc portion 13a of the sliding engagement member 13 and rotates. The latch tooth portion 5b and the locking tooth portion 13b mesh with each other. In this state, when the front door 41 is further closed in the closing direction, the meshing position of the latch tooth portion 5b and the locking tooth portion 13b becomes the tooth-like sliding surface 13c as the latch member 5 rotates in the closing direction. It slides and moves upward (the meshing range expands upward), and the sliding engagement member 13 is raised stepwise by the spring force of the spring member 15 as shown in FIG.

  Then, at the final stage of closing, the rotation of the latch member 5 and the rising of the sliding locking member 13 are stopped. At this time, the return rotation of the latch member 5 is prevented, and along with the closing rotation of the front door 41. The lock is gradually progressing. For this reason, the front door 41 is in a state where the front door 41 is rotated to a state where there is no gap with respect to the housing 40 and stopped, the latch member 5 is locked, and the latching portion 43 of the receiving member 42 is the latch member 5. Are completely restrained by the lock recess 6 and become locked.

  In this manner, when locking the front door 41 with respect to the housing 40 of the game machine, the locking portion 43 of the receiving member 42 enters the lock recess 6 of the latch member 5, and the latch tooth portion 5b is locked to the locking tooth portion. While slidingly engaging with 13b, the latch member 5 rotates in the locking direction against the spring force of the spring member 12, and when the closing of the front door 41 is completed, the locking tooth portion 13b becomes the latch tooth portion 5b. Since it is meshed and locked and locked, the front door 41 can be closed and locked to the housing 40 without rattling or gaps.

  For this reason, the front door 41 is closed even if there is a variation in the dimensions of each product such as the tolerance within the dimensional tolerance, the error of the mounting position, the dimensional error of the housing 40 or the front door 41, etc. At this time, when the latch member 5 is rotated to the latched position and is in the locked state, the front door 41 is completely closed, and the front door 41 can be closed and locked without backlash or gap.

  On the other hand, when unlocking, when a key is inserted into the cylinder lock 7 and rotated to the right, the cam member 8 rotates and the operating rod 4 slides downward. That is, when the key is turned to the right during the unlocking operation of the cylinder lock 7, the engaging convex portion 8a of the cam member 8 rotates downward to engage with the engaging portion 4b, and the operating rod 4 is lowered. At this time, in the latch unit 10, the sliding locking member 13 descends against the spring force of the spring member 15 via the engaging portion 4 a. Thereby, the latching tooth part 13b of the sliding latching member 13 leaves | separates from the latching tooth part 5b of the latch member 5, and the meshing of the latching tooth part 5b and the latching tooth part 13b is released. At this time, the latch member 5 rotates back in the counterclockwise direction of FIG. 18 by the spring force of the spring member 12, and the latching portion 43 of the receiving member 42 moves from the latch member 5 as shown in the left diagram of FIG. 18. It will come off and be unlocked.
