Description

DETAILED DESCRIPTION OF THE INVENTION <Industrial Application Field> The present invention relates to a locking device for a pachinko machine, and more particularly to a multiple structure locking device with an improved cylinder lock mounting structure.

<Prior Art> Conventionally, a front frame of a pachinko machine is provided with a front frame that can be opened and closed with respect to the machine frame of the pachinko machine, and a glass door frame that can be opened and closed with respect to the front frame. These frames are always locked and closed by a locking device installed inside the front frame, and the front frame and the glass door frame can be individually opened by unlocking the cylinder lock. .

Such a locking device includes a cylinder lock screwed via a base frame body attached to the inside of a front frame, a cam plate fixed to a lock shaft of the cylinder lock, and a cam plate engaged with the cam plate. And a locking mechanism having a separately operating front frame opening / closing connecting rod and a glass door frame opening / closing lifting rod, wherein the connecting rod is an engaged portion that engages with the cam plate behind the cam plate. Is formed.

In general, the pachinko machine's front frame and glass door frame are frequently opened and closed due to inspection adjustment, ball clogging, etc., and therefore, in the locking device, replacement due to wear of the cylinder lock, which is less durable than other parts. The need arises. In addition, a new cylinder lock may be replaced for security reasons such as loss of the key.

However, in the locking device as described above, the connecting rod interferes with the replacement of the cylinder lock, which requires a troublesome work such as removing the connecting rod. Therefore, the long connecting rod is formed by being divided into a main body portion and a rotating portion which is pivotally attached to the main body and is provided so as to be rotatable outwardly, and when the cylinder lock is exchanged, the latching of the rotating portion is released. There has been proposed a device in which the rear side of the cam plate is opened by rotating the cam plate outward (see, for example, Japanese Utility Model Laid-Open No. 62-4386).

On the other hand, the pachinko game hall is equipped with a large number of pachinko machines manufactured by a plurality of manufacturers, and the player can play the game by selecting one of the pachinko machines.

However, the cylinder lock of the locking device and the unlocking key thereof are exclusive to each maker, so that the staff must always carry a plurality of keys. Therefore, when the front frame or the glass door frame is opened, it takes a lot of time to search for the corresponding key, and the unlocking cannot be performed quickly. To cope with this, a dedicated key for activating the cylinder lock of the locking device of each pachinko machine is provided, and an additional lock that operates with a common key different from the dedicated key is attached to the front of the front frame, and one common key is used. An additional lock device capable of unlocking pachinko machines manufactured by a plurality of manufacturers has been proposed (see, for example, JP-A-62-236573).

<Problems to be Solved by the Invention> However, in the locking device having the conventional configuration as described above,
For example, in the device having the former configuration, when replacing the cylinder lock, it is necessary to remove the hook between the rotating portion and the main body portion of the connecting rod and open the rear side of the cam plate. Therefore, there is a problem that the replacement work requires a relatively large number of man-hours, and when the number of replacements is large, the man-hour for the replacement becomes a heavy burden.

Further, in the latter device, the cylinder lock has a double structure of the locking device and the additional locking device, so that there is a problem that the overall cost becomes high.

This invention was made in consideration of the above, and it is possible to replace cylinder locks easily and quickly, and to economically unify cylinder locks of pachinko machines from multiple manufacturers at each pachinko game hall. It is intended to provide a multi-structure lock device that can be unlocked with one common key.

<Means for Solving the Problems> The present invention was made in order to achieve the above-mentioned object, and a cylinder lock capable of forward and reverse rotation and an opening on the front side of the front frame of a pachinko machine and its opening A lock holder to which the cylinder lock can be mounted, a cam plate that is rotated by the cylinder lock, and a front frame opening / closing connecting rod and a glass that are separately operable by the rotation of the cam plate. In a locking device of a pachinko machine equipped with a locking mechanism provided with a lifting lever for opening and closing a door frame, the cylinder lock has an engaging portion for transmitting rotation to the cam plate at an end of a lock shaft, The cam plate has an engaged portion capable of engaging with the engaging portion of the cylinder lock, and when the cylinder lock is mounted on the lock holder, the engaging portion and the engaged portion engage with each other. And the cam plate rotates as the cylinder lock rotates. A multiple structure lock apparatus characterized by comprising been linked.

It is characterized by the configuration of the engaging portion and the engaged portion. In the following description, the same components as those in the first embodiment are designated by the same reference numerals and the description thereof will be omitted.

In the second embodiment, the lock shaft protruding to the rear end of the cylinder lock 11
A cross-shaped groove-like engaging portion 19 is formed at the end portion of 18. Further, a pair of positioning grooves 13A are formed on the outer peripheral portion of the cylinder lock 11 in parallel with the axis, and a fixing notch 16A is provided at a predetermined position.
Is provided.

On the inner wall of the lock holder 20, the positioning groove 13A is parallel to the axis.
Is formed with a pair of protrusions 26A, and screw holes 24 for fixing the cylinder lock 11 are provided at predetermined positions.

The cam plate (30) has a shaft hole (32a) having an axis line in common on one side thereof, and is a cross-shaped engaged part (32) engageable with the engaging part (19).
Is provided. The cam plate 30 has the shaft hole 32a,
The cam plate supporting member 33 formed in a U-shape is externally fitted to a mounting shaft 34 and is rotatably supported by a retaining ring 36.

Then, the mounting hole 25a of the lock holder 20 and the mounting hole 33a of the cam plate supporting member 33 pivotally supporting the cam plate 30 are overlapped with each other, and are fixed to the base portion 41a by the mounting screw 37 to lock the lock holder 2
0 and the cam plate 30 are integrally configured. This lock holder 20
The cylinder lock 11 is inserted through the front opening of the and the engaging portion 19 and the engaged portion 32 are connected. Then, the cylinder lock 11 is fixed by tightening the lock fixing screw 27 in the screw hole 24.

The present invention is not limited to the above description and the illustrated examples, and its embodiment can be modified without departing from the technical idea of the present invention.

For example, the engaging part and the engaged part may be engaged with each other so that rotation can be transmitted, and the shapes thereof are not particularly limited.

The cylinder lock may be fixed to the lock holder by being clamped by a retaining ring or a U-shaped spring on the outer periphery of the cylinder lock.

Further, this multi-structure lock device has the same operation and effect even if it is configured to be attached to the back surface side of the front frame directly or via the base plate and the cam plate thereof is engaged with the locking structure.

<Effect of Device> The multi-structure lock device according to the present invention has the above-described structure, and the cylinder lock can be mounted by inserting it into the lock holder from the front side of the front frame and can be pulled out to the front side. Can be taken out by.
