Description

[Detailed Description of the Invention] <Industrial Application Field> The present invention relates to a locking device for a pachinko machine that is configured so that the cylinder lock can be easily replaced.

<Prior art> There is a locking device that is attached to the front frame of a pachinko machine as a locking device for the front frame that is attached to the outer frame of the main body of a pachinko machine so that it can be opened and closed. A cylinder lock is attached to the center, hook members are pivotally supported at the upper and lower ends of the base frame, and a connecting rod that connects these hook members is engaged with a cam plate that is pivoted on the lock shaft of the cylinder lock. The pachinko machine is configured so that the front frame of the pachinko machine is unlocked by operating the hook member by rotating the cylinder lock.

By the way, in this type of locking device, the durability of the cylinder lock is lower than that of other parts, and the cylinder lock is damaged relatively early due to wear and the like, so it is necessary to replace only the cylinder lock. In addition, the same cylinder lock is generally used for the pachinko machines installed in a single pachinko parlor, and because a single key is used to unlock many pachinko machines, it is possible for this key to be lost or tampered with. If there is a possibility that the lock may be unlocked, it becomes necessary to replace all of these cylinder locks.

However, in conventional locking devices, a cylinder lock is installed so as to be inserted from the back side of the base frame, and an engaging claw that engages with a cam plate fixed to the lock shaft of the cylinder lock is covered from above. Since the cylinder lock is provided on the connecting rod, there is a problem in that the cylinder lock cannot be replaced without disassembling the entire locking device.

Therefore, the present inventor proposed a locking device for a pachinko machine in which the cylinder lock can be easily replaced in Japanese Utility Model Application Publication No. 58-157184.

<Problems to be solved by the invention> The above locking device divides the connecting rod arranged along the longitudinal direction inside the base frame at the middle part, and connects this intermediate connecting part to the connecting rods at both ends. It is connected with a pin etc. so that it can be pulled out upwards. However, since the intermediate connecting portion is bent so as to protrude outward at the cylinder lock portion, the operating rod for the glass frame, which is slidably disposed between the intermediate connecting portion and the support plate of the base frame body, is guided. In order to do this, it is necessary to provide pins, long holes, and other guide members, which complicates the structure and increases the number of processing and assembly steps.In addition, relatively high processing accuracy is required, leading to problems such as high costs. Ta.

<Means for Solving the Problems> The present invention has been developed in consideration of the above points, and has the following features: the cylinder lock can be easily replaced, the structure is simple, and processing and assembly are relatively easy. The present invention provides a locking device for a pachinko machine that can be configured as follows.

In other words, the pachinko machine locking device of the present invention is
A connecting rod is slidably disposed inside the base frame integrally formed with an L-shaped cross section by a mounting plate and a support plate, and both ends of the connecting rod have hooks pivoted to both ends of the support plate. In a locking device for a pachinko machine that is connected to a member and is unlocked by sliding a connecting rod by the operation of a cylinder lock attached to an intermediate portion of a mounting plate, the cylinder lock is provided with a mounting board, and the cylinder lock is provided with a mounting board. The cylinder lock is inserted from the inside of the base frame into a hole provided in the mounting plate, and is screwed to the mounting plate via the mounting board with the lock shaft protruding into the base frame.The lock shaft of the cylinder lock has a protrusion. A cam plate having a cylinder lock is pivotally attached, and an engagement hole is bored in the connecting rod at a position opposite to the protrusion of the cam plate, with which the protrusion engages when the protrusion rotates. Sometimes, the cam plate is located outside the engagement hole, and the upper part of the cam plate is open.

<Example> Hereinafter, an example of the present invention will be described based on the drawings.

Fig. 1 shows a plan view of the locking device of a pachinko machine, Fig. 2 shows a front view of the same, Fig. 3 shows a rear view of the same, and 1
The base frame is integrally formed by bending the mounting plate 1a and the support plate 1b into an L-shaped cross section. At both ends of the support plate 1b of the base frame body 1, a hook member 2 for locking and locking the front frame of the pachinko machine to the main body frame is attached to a second hook member 2 by a shaft 3.
It is pivotally supported so that it can slide in the direction of the arrow in the figure. The lower parts of the hook members 2 on both sides are connected by connecting rods 4, and the connecting rods 4 slide by a cam plate 17 that rotates due to the operation of a cylinder lock 15, which will be described later, to connect the hook members 2 on both sides.
It has a structure in which it slides in the direction of the arrow in Fig. 2. The mounting plate 1a of the base frame 1 is formed wide so as to protrude rearward at approximately the center thereof, and the support plate 1b is also bent at this portion so as to protrude rearward. A cam plate 17, which is pivoted to the lock shaft of the cylinder lock 15, is arranged in this wide part of the mounting plate 1a, but it cannot be illegally unlocked if a wire or the like is inserted through the gap between the front frame and the body frame of the pachinko machine. Because it is not done,
The support plate 1b near the protruding wide portion is formed wide. A connecting rod 4 connected between the hook members 2 at both ends
is arranged almost along the support plate 1b, and the connecting rod 4
An engagement hole 4a is formed approximately in the center of the cam plate 17, that is, at a position facing a first protrusion 17a of the cam plate 17, which will be described later. When the cam plate 17 rotates,
The first protrusion 17a engages, and by rotating the cam plate 17 counterclockwise in FIG.
slides to the left. In addition, at a position opposite to the engagement hole 4a in the support plate 1b, there is a long hole 2 for removing the tip of the first protrusion 17a when the cam plate 17 is rotated.
1 is drilled. Further, the connecting rod 4 is connected to the support plate 1b by a protrusion 12 provided protrudingly on the mounting plate 1a.
guided to slide along. moreover,
A long hole 19 is bored in the middle part of the connecting rod 4, and the pin 5
is fixed to the inside of the support plate 1b through this elongated hole 19, and the connecting rod 4 slides left and right while being guided by this pin 5. The connecting rod 4 is biased toward the right in FIGS. 1 and 2 by the coil spring 16 hooked between it and the mounting plate 1a, but when the pin hits the left end of the elongated hole 19, the connecting rod 4 4 acts as a stopper during rightward movement. Conversely, it also serves as a stopper when the connecting rod 4 is moved to the left.

A glass frame operating rod 9 is disposed between the substantially central portion of the rearwardly projecting support plate 1b and the connecting rod 4 disposed along this. An engaging piece 10 is provided at the upper part near the end of the glass frame actuating rod 9 to protrude outward and engage with an actuating piece of a glass frame locking device (not shown) to unlock it. 10 projects rearward through a long hole 11 provided in the support plate 1b. The glass frame operating rod 9 is operated by a coil spring 20 suspended between it and the mounting plate 1a.
This coil spring 20 is biased toward the left in the figure.
The second protrusion of the cam plate 17 of the cylinder lock 15 can be slid to the right within a certain range against the spring force of the cylinder lock 15. By engaging the portion 17b and rotating the cam plate 17 clockwise, the glass frame operating rod 9 slides to the right. Incidentally, a long hole 22 is formed in the protruding portion of the support plate 1b to allow the tip of the cam plate 17 to be removed when the cam plate 17 rotates.

The cylinder lock 15 is attached to the lower side of a small mounting board 18 with its lock shaft protruding upward, and a cam plate 17 having a first protrusion 17a and a second protrusion 17b is pivotally attached to the lock shaft. The cylinder lock 15 to which the mounting board 18 and cam plate 17 are attached in this way is mounted on the mounting plate 1.
The mounting board 18, which serves as a flange, is inserted from above into a hole provided in the wide part of the mounting plate 1a, and is screwed onto the mounting plate 1a by fixing screws 23.

The first protrusion 17a of the cam plate 17 has an L-shaped cross section and projects inside the base frame 1 perpendicularly to the cam plate 17, with its end facing outward. Further, the second protrusion has a substantially rectangular shape and projects horizontally from the cam plate.

The cam plate 17, which is pivoted to the cylinder lock 15 attached to the mounting plate 1a, is viewed from directly above the mounting plate 1a as shown in FIG. 1 when the cylinder lock 15 is not operated. , does not intersect with the connecting rod, that is, the first and second protrusions 17a, 17b of the cam plate 17 are located outside the respective engagement holes 4a, 9a. Therefore, since the upper part of the cam plate 17 is open, the cylinder lock 15 can be opened by removing the two fixing screws 23.
is easily removed together with the mounting board 18, and the cylinder lock 15 can be easily replaced. In this embodiment, the planar shape of the protrusions 17a, 17b of the cam plate 17 is approximately rectangular, but when the cylinder lock 15 is not operated, the engagement holes 4a, 9a formed in the connecting rod are closed.
The shape is not limited as long as it comes out from the cylinder lock 15 and can be engaged with the engagement holes 4a and 9a to slide the connecting rod 4 or the glass frame operating rod when the cylinder lock 15 is activated.

The locking device configured in this manner is installed by screwing the mounting plate 1a onto the vertical beam of the front frame of the pachinko machine with the left side in FIG. 2 facing upward.
A receiver for the hook member 2 is fixed to the main body frame side. On the other hand, the glass frame locking device is attached to the inner surface of the front frame (not shown), and a locking piece attached to the glass frame is locked in a groove of the locking device to lock the glass frame. The structure is such that the operation of the piece 10 moves the operating piece of the locking device to unlock it.

Therefore, first, when opening the front frame, the cylinder lock 15 is operated with a key to rotate the cam plate 17 counterclockwise in FIG. Then, as shown in FIG.
to move the connecting rod 4 to the left. As a result, the hook members 2 pivotally supported at both ends of the support plate 1b are tilted in the direction of the arrow in FIG. 2 and disengaged from the not-shown receiver, thereby unlocking the front frame.

On the other hand, when unlocking the glass frame, cylinder lock 1
5 in the opposite direction to the above to rotate the cam plate 17 clockwise in FIG. Then, as shown in FIG. 5, the second projection 17b of the cam plate 17 rotates in the direction of the arrow, engages with the engagement hole 21 of the glass frame operating rod 9, and moves it to the right. Therefore, the engagement piece 10 protruding from the glass frame actuation rod 9 moves the actuation piece of a glass frame locking device (not shown), and the glass frame is unlocked.

In addition, in the above-mentioned embodiment, the present invention was applied to a double lock having both the functions of locking the glass frame and locking the front frame, but it is also possible to apply the present invention to a locking device for only the front frame.

<Effects of the invention> As explained above, according to the locking device for a pachinko machine of the invention, the cylinder lock is inserted from the inside of the base frame into the hole provided in the mounting plate, and the lock shaft is inserted into the base frame. In the protruding state, it is screwed to the mounting plate via the mounting board, a cam plate having a protrusion is attached to the lock shaft of the cylinder lock, and a protrusion is provided at a position opposite to the protrusion of the cam plate on the connecting rod. An engagement hole is drilled that engages when the cylinder lock is rotated, and the protrusion of the cam plate is located outside the engagement hole when the cylinder lock is not activated, and the upper part of the cam plate is opened. , If you remove the screws from the mounting board with the locking device installed on the pachinko machine,
The cylinder lock can be removed from the mounting plate, making it easy to replace the cylinder lock, and
Compared to the conventional one, the connecting structure of the connecting rod is simplified, the number of parts is reduced, and the number of processing and assembly steps are also reduced, making it possible to significantly reduce manufacturing costs. In addition, even if there is an operating rod for the glass frame, this operating rod is inserted between the connecting rod and the support plate and is slidably supported, so there is no need to provide pins, slots, or other guide members, making manufacturing easier. .
