Description

[Technical Field]

[0001] The present invention relates to a locking device for a gaming machine, and more particularly to a locking device that is provided at the front of a gaming machine such as a slot machine and locks a front door that opens and closes towards the front and back. [Background technology]

[0002] For example, a slot machine typically has a reel unit with reels that rotate to display symbols located in the upper part of the cabinet, a medal payout device that pays out medals located below the reel unit, and a front door that can be opened and closed to close the front of the cabinet. The front door is typically supported on its left side by a hinge device so that it can be opened and closed, and switches such as a start switch and a stop switch, decorative lamps, etc. are provided on the front of the front door. A locking device with a cylinder lock is also attached to the right side of the front door, and the front door is locked to the cabinet by the locking device.

[0003] On the other hand, in slot machines, the upper reel unit and the lower medal payout device are adjusted or inspected separately during inspection or when filling with medals, so a separated type slot machine has been proposed in Patent Document 1 below, in which the upper reel unit and the lower medal payout device are separated into cabinets, and each is provided with an upper front door and a lower front door, allowing the doors to be opened and closed separately. [Prior art documents] [Patent documents]

[0004] [Patent Document 1] Japanese Patent Application Laid-Open No. 2003-250959 [Patent Document 2] JP 2017-148197 A Summary of the Invention [Problem to be solved by the invention]

[0005] When replenishing medals in the medal payout device of the above slot machine during business hours, medals can be replenishing by opening only the front door without opening the reels that display the symbols.

[0006] However, the lower front door of this slot machine has switches and decorative parts that protrude forward and is configured to open to the right via a hinge device on the left side.As a result, when the lower front door is opened, the protruding part of the lower front door protrudes further to the left from the left side of the cabinet, which creates the problem of the protruding part of the lower front door easily interfering with adjacent equipment installed on the island in the hall. Therefore, it was considered to make the lower front door a door that opens up and down towards the front of the cabinet via a lower hinge.However, because this door would have a built-in medal payout device, a front door that opens up and down towards the front would require a highly secure locking device to lock it. Conventional locking devices for locking the front door of a game machine are manufactured with various structures, but most of the locking devices have a door that is attached to the left side via a hinge device so that it can be opened sideways, so the locking device is only provided on the side opposite the hinge device. Therefore, if a conventional locking device is applied as is, only one side will be locked and the other side will be unlocked, which can easily cause security problems.

[0007] Therefore, the present inventors proposed a locking device structured to lock both the left and right sides of the lower front door in the above-mentioned Patent Document 2. Although this locking device can reliably lock both the left and right sides of the lower front door, the locking rod of the locking part slides up and down to lock and unlock, and therefore there was a problem in that the sliding frictional resistance of the locking rod was likely to hinder smooth locking and unlocking operations.

[0008] The present invention solves the above-mentioned problems and aims to provide a locking device for a game machine that can lock a front door attached to the front of a cabinet, which opens and closes towards the front and back, with high security and can smoothly lock and unlock it. [Means for solving the problem]

[0009] The locking device for a game machine according to the present invention comprises: A front door that opens and closes toward the front and rear is attached to the front of the cabinet of the game machine via a lower hinge, and a locking device for the game machine locks the front door, a receiving bracket attached to both sides of the cabinet and having a locking portion; a locking unit attached to the inside of the front door and provided at both ends of a single base frame body, the locking unit having a latch member that is engaged with the engaging portion of the receiving metal fitting; a cylinder lock attached to the front surface of the base frame via a lock mounting frame in the longitudinal direction of the base frame; a cam member fixed to the lock shaft of the cylinder lock; Equipped with The locking unit is the latch member is pivotally supported on the inside of the mounting frame; a rotation locking member is pivotally supported on the inside of the mounting frame adjacent to the latch member; and a spring member is hooked between the latch member and the rotation locking member; The rotary locking members on both sides are connected to each other by a connecting rod and are supported by a shaft so as to be rotatable in synchronization, an engaging lever is attached to the connecting rod so as to protrude toward the cam member, and the latch member is provided with a latch groove into which a locking pin protruding from the rotary locking member enters to lock it, When the front door is closed relative to the cabinet, the locking portion of the receiving metal fitting pushes and rotates the latch member, and as the latch member rotates, the locking pin is engaged with the latch groove to lock the latch member. When the cylinder lock is unlocked, the rotating locking members on both sides rotate in the unlocking direction via the cam member, the engaging lever and the connecting rod, the locking pins come out of the latch grooves of the latch members on both sides, the latch members rotate to the unlocking side, and the locking section is unlocked.

[0010] According to the locking device for a game machine of this invention, when the front door is closed on the cabinet, the locking portion of the receiving metal fitting pushes and rotates the latch member, and as the latch member rotates, the locking pin engages with the latch groove, locking the latch member. When the cylinder lock is unlocked, the rotating locking members on both sides rotate in the unlocking direction via the cam member, engagement lever, and connecting rod, causing the locking pin to disengage from the latch grooves of the latch members on both sides and the latch members to rotate to the unlocking side, unlocking the locking portion, thereby locking the front door with high safety and allowing for smooth locking and unlocking. Furthermore, because the front door of the cabinet is designed to open and close toward the front, interference with adjacent equipment installed in the hall island can be avoided when the front door is opened.

[0011] Here, the base frame can be configured so that it is attached horizontally to the top of the front door, an opening is provided in a part of the base frame, an engaging lever attached to the connecting rod protrudes to the front side through the opening and engages with the cam member, and the mounting frame of the locking unit protrudes at a right angle to the back side of the base frame, and the latch member and the rotary engaging member are each pivotally supported inside the mounting frame by a support shaft that is approximately parallel to the lock shaft of the cylinder lock. [Effects of the Invention]

[0012] According to the locking device for a game machine of this invention, the front door attached to the front of the cabinet, which opens and closes towards the front and back, can be locked with high security and can be locked and unlocked smoothly. [Brief explanation of the drawings]

[0014] An embodiment of the present invention will be described below with reference to the drawings. The locking device for a gaming machine shown in Figs. 1 to 16 is a locking device that locks a front door 30 that is attached to the front of a cabinet K of, for example, a slot machine in an openable and closable manner. As shown in Figs. 15 and 16, the front door 30 has a structure in which the upper part opens up and down toward the front, and lower hinges 42, 43 are attached to the lower front part of the cabinet K. When unlocking the front door 30, the upper part is pulled toward the front via the lower hinges 42, 43 to open it.

[0015] Receiving brackets 32, 33 are attached vertically to the bottom of both sides inside the cabinet K. The receiving brackets 32, 33 are formed symmetrically, and pivotal support portions 36, 37 are attached to vertically long base frames 34, 35, respectively, so that they protrude inward. Locking pins (locking portions) 38, 39 are attached inside the pivotal support portions 36, 37, and both ends of the locking pins 38, 39 are pivotally supported by the base frames 34, 35 and the pivotal support portions 36, 37, and the locking pins 38, 39 are attached horizontally inside the receiving brackets 32, 33. Note that the locking pins 38, 39 are pin-shaped shafts in this example, but they may have other shapes.

[0016] As shown in Figures 5, 6, and 8, the locking device has a single, horizontally long base frame 1, with left and right locking units 10, 20 attached to the inside (back side) of the wide sections at both ends of the base frame 1. The base frame 1 is formed by bending a long steel plate into a roughly L-shaped cross section, and has the necessary strength.

[0017] The locking units 10, 20 are designed to lock the locking pins 38, 39 of the receiving brackets 32, 33 by holding them in the locking grooves 16, 26 of the latch members 12, 22 when locked, and the locking units 10, 20 on both sides are formed symmetrically, as shown in Figure 8.

[0018] As shown in Figure 8, the cylinder lock 2 is attached to the front of the base frame 1 via a lock mounting frame 3, facing horizontally and parallel to the longitudinal direction of the front of the base frame 1. The lock mounting frame 3 is formed by bending a steel plate into a roughly U-shape and is fixed to the front of the base frame 1. The cylinder lock 2 is attached so that its lock shaft 2a is inserted inside the lock mounting frame 3, and a cam member 4 is fixed to the tip of the lock shaft 2a, and the cam member 4 rotates in response to the operation to unlock the cylinder lock 2. The axial direction of the axis C (Figure 8) of the cylinder lock 2, including the lock shaft 2a, is parallel to the longitudinal direction of the base frame 1.

[0019] On the other hand, as shown in FIG. 8, an opening 1a is formed in the base frame 1 near the cam member 4, and an engaging lever 6 protrudes from this opening 1a toward the cam member 4. The cam member 4 has a slightly longer lever-like portion. During the unlocking operation, the tip of the lever pushes down the engaging lever 6 on the connecting rod 5 side, rotating the rotary locking members 13 and 23. In other words, the rotational force of the cam member 4 during the unlocking operation is transmitted to the connecting rod 5 via the engaging lever 6, causing the connecting rod 5 to rotate around its longitudinal axis. This longitudinal axis is disposed approximately parallel to the C-axis of the cylinder lock 2. Note that, although a long cylinder lock 2 is used in this example, a standard short cylinder lock may also be used. The longitudinal axis of the connecting rod 5 may also be non-parallel to the C-axis. A cover 45 is attached to the lock mounting frame 3 of the cylinder lock 2 so as to cover the cam member 4. As shown in Figure 8, the locking units 10, 20 on both sides are fixed to both ends of the base frame 1 and comprise mounting frames 11, 21 that protrude from the back side perpendicular to the front of the base frame 1, latch members 12, 22 that are rotatably supported on support shafts 17, 27 inside the mounting frames 11, 21, rotary locking members 13, 23 that are adjacent to the latch members 12, 22 and supported on support shafts 18, 28 inside the mounting frames 11, 21, and a single spring member 7 that is hung between the latch members 12, 22 and the rotary locking members 13, 23.

[0020] The locking units 10 and 20 on both sides are configured symmetrically, and Figure 9 shows an exploded perspective view of the right locking unit 10. The left locking unit 20 is symmetrical to the right locking unit 10, and the structures of the locking units 10 and 20 are almost identical.

[0021] 8 and 9, the mounting frame 11 of the locking unit 10 has support shafts 17 and 18 that are supported parallel to the axis C (FIG. 8) at the portion that protrudes perpendicularly from the base frame 1 toward the rear side, and the latch member 12 is supported on the support shaft 17, and the rotary locking member 13 is rotatably supported on the support shaft 18. The support shafts 17 and 18 are attached approximately parallel to the lock shaft 2a of the cylinder lock 2.

[0022] The latch member 12 and the rotary locking member 13 are adjacently supported on a right-angle bent portion of the mounting frame 11, and the latch member 12 is provided with a latch groove 15 and a locking groove 16. The rotary locking member 13 is fitted with a locking pin 14 that enters the latch groove 15 when locked. The locking groove 16 is the portion where the locking pin 38 of the receiving bracket 32 ​​is introduced and locked. The mounting frame 11 is provided with an opening 11b on the back side for introducing the locking pin 38.

[0023] As shown in Fig. 9, the rotary locking member 13 has a connecting portion 13a bent at a right angle, and the end of the connecting rod 5 is connected to this connecting portion 13a. A spring member (coil spring) 7 is hooked between the latch member 12 and the rotary locking member 13. When the latch member 12 is unlocked, the spring member 7 biases the latch member 12 so that its locking groove 16 is exposed on the back side (the side of the receiving metal fitting 32) as shown in Fig. 7. When the latch member 12 is locked, the spring member 7 holds the locking pin 14 inserted into the latch groove 15, and acts to hold the locking pin (locking portion) 38 of the receiving metal fitting 32 in the locking groove 16 as shown in Fig. 10.

[0024] During the unlocking operation, the rotational force of the cam member 4 of the cylinder lock 2 is transmitted to the connecting rod 5 via the engaging lever 6, and as the connecting rod 5 rotates, the rotary locking member 13 rotates, disengaging the locking pin 14 from the latch groove 15, and the spring force of the spring member 7 causes the latch member 12 to rotate in the direction of the arrow in Fig. 10 (clockwise), thereby unlocking. Also, during unlocking, as shown in Fig. 7, the spring force of the spring member 7 causes the rotary locking member 13 and the engaging lever 6 to assume the state shown in Fig. 7, with the tip of the cam member 4 of the cylinder lock 2 abutting against the engaging lever 6. A cover 10a is attached to the inside of the locking unit 10.

[0025] As shown in Figure 8, the mounting frame 21 of the left-side locking unit 20 has support shafts 27 and 28 supported parallel to the axis C at a portion that protrudes perpendicularly from the base frame 1 toward the rear side, with the latch member 22 supported on the support shaft 27 and the rotary locking member 23 rotatably supported on the support shaft 28. The latch member 22 and the rotary locking member 23 are supported adjacently on a right-angle bent portion of the mounting frame 21, and the latch member 22 is provided with a latch groove 25 and a locking groove 26. A locking pin 24 is attached to the rotary locking member 23, which enters the latch groove 25 when locked. When locked, the locking groove 26 introduces a locking pin 39 of the receiving bracket 33 to lock it.

[0026] As shown in Figure 8, the rotary locking member 23 is provided with a connecting portion 23a, and the end of the connecting rod 5 is connected to this connecting portion 23a. In addition, a spring member (coil spring) 7 is hung between the latch member 22 and the rotary locking member 23. This spring member 7 exposes the locking groove 26 on the back side (the side of the receiving metal fitting 32) of the latch member 22 when unlocked. In addition, the spring member 7 holds the locking pin 24 that has entered the latch groove 25 when locked, and biases the locking pin (locking portion) 39 of the receiving metal fitting 33 so that it is held in the locking groove 26.

[0027] As a result, during an unlocking operation, the rotational force of the cam member 4 of the cylinder lock 2 is transmitted to the connecting rod 5 via the engaging lever 6. When the connecting rod 5 rotates, the rotary engaging member 23 rotates, disengaging the engaging pin 24 from the latch groove 25. The spring force of the spring member 7 then causes the latch member 22 to rotate to the unlock position, unlocking the lock. Furthermore, during unlocking, the rotary engaging member 23 and the engaging lever 6 are in a state where the tip of the cam member 4 of the cylinder lock 2 abuts the engaging lever 6 due to the spring force of the spring member 7, exposing the engaging groove 26 of the latch member 22 to the rear side and releasing the engaging pin 39 of the receiving bracket 33. A cover 20a is attached to the inside of the locking unit 20. A cover 46 is attached to the inside of the base frame 1, and a cover 20a is attached to the inside of the locking unit 20.

[0028] Next, the usage and operation of the locking device for the game machine configured as described above will be explained. As shown in Figure 15, the locking device is attached to the inside of the upper part of the front door 30, which is attached to the lower part of the game machine via lower hinges 42 and 43, facing horizontally (left and right from the front of the game machine toward the front door 30).

[0029] As shown in Figure 15, the cylinder lock 2 faces the right side of the front door 30. A decorative portion is usually provided on the front surface of the front door 30, so the keyhole at the end of the cylinder lock 2 is exposed on the right side of the decorative portion. The front door 30 has both lower sides pivotally supported by lower hinges 42, 43, and is opened by pulling the upper part toward the front and closed by pushing it toward the rear. The receiving brackets 32, 33 have vertically elongated base frames 34, 35, and locking pins 38, 39 are attached horizontally to the inside of the base frames 34, 35. The locking pins 38, 39 are firmly attached to receiving portions fixed to the base frames 34, 35 so that both ends of the pins are held in place.

[0030] Such receiving brackets 32, 33 are attached vertically on both sides of the lower inside of the cabinet K, and their locking pins 38, 39 are attached horizontally, that is, so that they are parallel to the lock shaft 2a and support shafts 17, 27 of the cylinder lock 2 when the front door 30 is closed.

[0031] As shown in Figures 14 and 16, when the front door 30 is opened and the locking device is in the unlocked state, the latch member 12 stops in the position where its engagement groove 16 is open within the opening 11b, as shown in Figure 7, and maintains that state.

[0032] In this state, when the front door 30 is closed, as shown in Figure 7, the locking pins 38, 39 of the receiving brackets 32, 33 relatively enter the locking grooves 16, 26 of the latch members 12, 22, and the latch members 12, 22 rotate in the direction of the arrow in Figure 7 (counterclockwise) and are pushed into the locking grooves 16, 26 as shown in Figure 10.

[0033] At this time, the rotary locking members 13, 23 are biased by the spring member 7 and rotate in the same direction as the latch members 12, 22, and rotate to the position shown in Fig. 10. At this time, the locking pins 14, 24 of the rotary locking members 13, 23 enter the latch grooves 15, 25 of the latch members 12, 22, thereby locking the latch members 12, 22 at the position shown in Fig. 10, and the locking pins 38, 39 of the receiving metal fittings 32, 33 are held in the locking grooves 16, 26 within the openings 11b, 21b of the mounting frames 11, 21, thereby entering a locked state.

[0034] When unlocking, inserting the key into the cylinder lock 2 and turning it to the right causes the cam member 4 to rotate counterclockwise in Fig. 10, pushing down the engagement lever 6 with its tip, and rotating the rotary locking members 13, 23 of the locking units 10, 20 on both sides clockwise in Fig. 10 via the connecting rod 5. At this time, as shown by the arrows in Fig. 10, the locking pins 14, 24 of the rotary locking members 13, 23 retract and disengage from the latch grooves 15, 25 of the latch members 12, 22, and the spring force of the spring member 7 causes the latch members 12, 22 to rotate clockwise in Fig. 10, releasing the locking pins 38, 39 of the receiving metal fittings 32, 33 as shown in Fig. 7, thereby achieving an unlocked state.

[0035] In this way, when the front door 30 is closed relative to the cabinet K, the locking pins 38, 39 of the receiving metal fittings 32, 33 push and rotate the latch members 12, 22, and as the latch members 12, 22 rotate, the locking pins 14, 24 engage with the latch grooves 15, 25 to lock the latch members 12, 22, and when the cylinder lock 2 is unlocked, the rotating locking members 13, 23 on both sides rotate in the unlocking direction via the cam member 4, the engaging lever 6 and the connecting rod 5. As a result, the locking pins 14, 24 are disengaged from the latch grooves 15, 25 of the latch members 12, 22 on both sides, the latch members 12, 22 rotate to the unlocking side, and the locking units 10, 20 are unlocked, so that the front door 30 can be locked with high safety and can be locked and unlocked smoothly.
