DETAILED DESCRIPTION OF THE INVENTION [0001] BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a base member
Disposed between the base member and the opening / closing member.
The present invention relates to a hinge device that is swingably opened and closed. [0002] 2. Description of the Related Art Hinge devices as described above are frequently used in game machines.
For example, the outer frame of a pachinko machine
A hinge device disposed between the front frame and the front frame is exemplified. Snap
The hinge device of the machine is an outer frame with an outer opening
Front of each other with the front frame for mounting and closing according to the opening area of the
It consists of a pair of upper and lower hinge devices arranged on the upper and lower left sides. Up
Each of the lower hinge devices should be horizontal as shown in FIG.
A shaft support hole 802 is formed in the first plate-shaped portion 801 provided.
First hinge member 800 and a second plate horizontally disposed
A support shaft 807 protruding upward from the shape 806 is fixedly provided.
And a second hinge member 805. Such a structure
In the pair of upper and lower hinge devices, the shaft support hole 802
The first and second hinge members 80 are fitted with the support shaft 807.
0,805 is connected horizontally and relatively rotatably.
The front frame is pivotally opened and closed and detachably supported with respect to the outer frame
It is configured to However, in the above-mentioned conventional hinge device,
When trying to attach the front frame to the outer frame,
The shaft support hole 802 and the support shaft 807 of both hinge devices are
Must be engaged (aligned with each other)
And there is a problem that the work is not easy. Special
In addition, when installing in a game facility, the outer frame is fixed to the game island.
It is fixed and immovable, and the front
Considerable weight (for example, mechanical panel, control device, etc.)
(For example, 15 to 20 kg), and the hinge device is heavy.
Because it is located on the side distant from the center position,
The problem that the mounting work for positioning is extremely difficult
was there. In view of such a problem, for example, FIG.
As shown in the figure, the plate-like portion 801 of the first hinge member 800 '
The introduction opening 803 connected to the shaft support hole 802 from the outside surface
The left and right sides of the support shaft 807 of the second hinge member 805 'are formed.
Cut into a plane to form plane portions 807a, 807a
And the width of the left and right plane portions 807a, 807a of the support shaft 807 is
It is configured to be slightly narrower than the width of the introduction opening 803.
It is known. In this configuration, the right and left
Pass the flat portions 807a, 807a through the introduction opening 803
The support shaft 807 into the shaft support hole 802 from the side.
The first and second hinges can be inserted in this state.
When the members 800 'and 805' are relatively rotated horizontally,
The left and right flat portions 807a, 807a are turned into the shaft support holes 802.
It is held movably. With this configuration, the shaft support hole
Without aligning the 802 and the support shaft 807 up and down.
The support shaft 807 is moved in the lateral direction to fit in the shaft support hole 802.
To attach the front frame to the outer frame.
The work becomes simple. [0005] SUMMARY OF THE INVENTION
In the case of forming, the introduction opening 803 of the shaft support hole 802 and the support shaft 8
07 with the left and right plane portions 807a, 807a facing each other
When the front frame is rotated until the support shaft 807 is
There is a problem that it comes off and the front frame comes off. The present invention has been made in view of the above problems and problems.
The front frame, etc., is provided in a simple configuration with respect to the outer frame, etc.
It can be easily attached and detached, and once attached
Is to prevent the front frame etc. from coming off regardless of its rotation position.
A game machine butterfly that is designed to be able to be held securely
It is intended to provide a numbering device. [0007] [MEANS FOR SOLVING THE PROBLEMS]
In order to never achieve the object, a hinge device according to the first aspect of the present invention
The base is located on the top and bottom of the gaming machine,
For example, with respect to the outer frame 1) in the embodiment, an opening / closing member (for example,
The front frame 2) in the embodiment is hinged so that it can swing open and close freely.
At least one butterfly in a pair of upper and lower hinge devices to be moved
The numbering device, wherein one of the base member and the opening / closing member
A first hinge member fixed to one member (for example,
Upper fixture 10) in the state, and the second
Hinge member (for example, upper swing metal fitting 50 in the embodiment)
And the first hinge member is fixed to the one member.
And a horizontally protruding plate-like portion.
The hinge member is fixed to the other member and projects downward.
(For example, the support shaft 54 in the embodiment).
It is composed. The plate-shaped part is the shaft support hole and the shaft support
A guide hole that extends rearward by connecting to the hole is formed
A plate member formed with an introduction portion that opens laterally to the plate member;
At least a portion of the member including the shaft support hole and its surroundings
Mounted on the lower surface and below the shaft support hole
And a lower lid member having a lock hole formed at
On the other hand, it projects downward from the lower end surface of the shaft inside the shaft.
A lock pin that can be extended is provided so that it can move up and down.
You. Then, the shaft is introduced into the guide hole from the introduction portion.
And moved to the shaft support hole along the guide hole.
After that, move the lock pin downward and insert the lower end into the lock hole.
To hold the shaft in the shaft support hole.
Has been established. [0008] The hinge according to the present invention configured as described above.
According to the device, when connecting the front frame to the outer frame,
The upper and lower two shaft support holes and the support shaft are simultaneously aligned (core
Delicate adjustment operation such as
And a second hinge portion for at least one hinge device.
Guides the shaft of material from the introduction on the side of the first hinge member
Penetrate the hole from the side, then move the shaft forward
Simple operation of moving the lock pin downward after
To position the shaft inside the shaft support hole and turn freely and off
And the first and second hinge members are hinged.
Can be di-bonded. [0009] Further, in the plate-shaped portion, the rear side from the shaft support hole.
Since the guide hole extends, it is located in the shaft support hole.
The placed shaft is at least supported when pulled forward.
It contacts the plate at the front side of the hole. Because of this, opening and closing
Acts horizontally forward on the hinge connection when the member is opened
Force acts on the front of the shaft support hole and is received by the plate
And sufficient strength can be secured. In particular, like this
The force acting horizontally forward on the hinge connection part is applied to the plate-shaped part.
Formed by a plate member (which is generally made of steel plate)
To be inserted into the lock hole of the lower lid member.
You can prevent this force from acting on Kupin,
This prevents damage to the lock pin and improves the resistance of the hinge device.
The durability can be improved. [0010] DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS A hinge of a gaming machine according to the present invention will be described below.

be able to. Further, in the plate-like portion, from the shaft support hole
Since the guide hole extends, it is located in the shaft support hole.
The placed shaft is at least supported when pulled forward.
It contacts the plate at the front side of the hole. Because of this, opening and closing
Acts horizontally forward on the hinge connection when the member is opened
Force acts on the front of the shaft support hole and is received by the plate
And sufficient strength can be secured. In particular, like this
The force acting horizontally forward on the hinge connection part is applied to the plate-shaped part.
Formed by a plate member (which is generally made of steel plate)
To be inserted into the lock hole of the lower lid member.
You can prevent this force from acting on Kupin,
This prevents damage to the lock pin and improves the resistance of the hinge device.
The durability can be improved.
