BACKGROUND OF THE INVENTION
The present invention relates to a hinge mechanism that is disposed between a base member and an opening / closing member and connects the base member and the opening / closing member so as to be swingable and openable relative to each other.
[0002]
[Prior art]
The hinge mechanism as described above is widely used in gaming machines, and one example thereof is a hinge mechanism disposed between an outer frame and a front frame in a pachinko machine. The hinge mechanism of a pachinko machine is composed of a pair of upper and lower hinge mechanisms disposed on the upper left and right sides of the front of an outer frame having an outer opening and an opening / closing front frame adapted to the opening surface area.
[0003]
As shown in FIG. 18, each of the upper and lower hinge mechanisms includes a first hinge member 500 in which a shaft support hole 502 is formed in a first plate-like portion 501 disposed horizontally, and a second hinge disposed horizontally. The second hinge member 505 is fixedly provided with a support shaft 507 protruding upward from the plate-like portion 506. In the pair of upper and lower hinge mechanisms having such a configuration, by inserting the support shaft 507 into the shaft support hole 502 and connecting the first and second hinge members 500 and 505 horizontally and relatively rotatably, the outer frame On the other hand, the front frame is configured to support the swingable opening / closing and detachable.
[0004]
However, in the conventional hinge mechanism as described above, when the front frame is to be attached to the outer frame, the shaft support hole 502 and the support shaft 507 of both the upper and lower hinge mechanisms are aligned together (axis There was a problem that it was not easy to work because it had to be engaged (with the hearts aligned). In particular, when mounting in a gaming facility, the outer frame is fixed to the game island and cannot be moved, and the front frame is incorporated with a game board, back set board, control device, etc. For example, since the hinge mechanism is located on the side away from the center of gravity, there is a problem that the mounting operation for positioning the upper and lower two locations is extremely difficult.
[0005]
In view of such a problem, for example, as shown in FIG. 19, an introduction opening 503 connected to the shaft support hole 502 from the outer surface is formed in the plate-like portion 501 of the first hinge member 500 ′, and the second hinge member 505 is formed. The left and right sides of the supporting shaft 507 are cut into a flat shape to form flat portions 507a and 507a, and the width of the left and right flat portions 507a and 507a of the supporting shaft 507 is slightly narrower than the width of the introduction opening 503. It is known.
[0006]
In this configuration, the support shaft 507 can be inserted into the shaft support hole 502 from the side by passing the left and right plane portions 507a and 507a of the support shaft 507 through the introduction opening 503, and in this state, the first and second If the hinge members 500 ′ and 505 ′ are horizontally rotated relative to each other, the left and right plane portions 507 a and 507 a are rotatably held in the shaft support hole 502. With this configuration, the support shaft 507 can be moved in the lateral direction and fitted into the shaft support hole 502 without aligning the shaft support hole 502 and the support shaft 507 in the vertical direction. The work of attaching the front frame becomes easy.
