Description

[Detailed explanation of the idea] This idea relates to the front style of pachinko machines.

As shown in Fig. 1, the front frame of a pachinko machine includes a wooden front frame main body 1 that is shaped like a square frame with a square window hole in the center, and a front frame that is glued to the front of the main body to cover the front of the main body. It is constructed of a decorative board 3 made of a hard resin board, and a metal frame 6 that is provided with a glass door 7 that can be opened and closed and that is attached with screws along the window periphery on the front side of the front frame body 1 with the decorative board 3 in between. has been done.

Conventionally, as shown in FIG. 2, the window 4' opened in the center of the decorative board 3' is usually
Since the opening is the same size as the corner window hole 2',
When fastening the metal frame 6' to the front frame body 1', the decorative plate 3'
Since the fastening screw 8' is screwed into the decorative board 3'
It had the disadvantage of cracking and breakage.

Therefore, as shown in Fig. 3, in order to prevent the decorative board from cracking or breaking, there is a case where the window 4'' of the decorative board 3'' is opened larger than the corner window hole of the front frame body 1''. In this case, when the metal frame 6'' is fastened to the front frame main body 1'', the metal frame 6''
" is inclined inward as shown in the figure, so when opening and closing the glass door 7" with respect to the metal frame 6", the edge 7A of the glass door 7"
'' hits the corner 6A'' of the metal frame 6'', making it difficult to open and close the glass door 7''.

In view of the above reasons, the purpose of the present invention is to provide a front frame for a pachinko machine that does not hinder the opening and closing of the glass door and can prevent damage to the decorative board caused by screws for fastening the metal frame. be.

An embodiment of the present invention will be described below with reference to FIGS. 4 to 6.

In the figure, reference numeral 1 denotes a wooden front frame body in the shape of a square frame, with a square window hole (hereinafter simply referred to as a window) in the center.

)2 is open.

Reference numeral 3 denotes a decorative board which is adhered to the front surface of the front frame main body 1 and covers the front surface of the main body, and is made of a hard resin board such as a melamine resin board or a polyester resin board.

This decorative board 3 is made of a single board, and is shaped into a square frame shape of the same size as the front frame body 1 by punching with a press.
A window 4 opening to the same size is simultaneously punched out.

Further, a plurality of escape holes 5 to 5 are formed in a concave arc shape on the peripheral edge of the window 4 of the decorative board 3, corresponding to the screws 8 to 8 for fastening the metal frame.

Note that the relief holes 5 to 5 can be punched out at the same time using a punching die using the press, or they can be cut out later.

Thus, the metal frame 6, which allows the glass door 7 to be opened and closed, is fastened along the window periphery on the front surface of the front frame main body 1, with the decorative board 3 in between, via the fastening screws 8.

Now, since the screws 8 for fastening the metal frame 6 described above are inserted through the escape holes 5 of the decorative board 3 and screwed into the front frame main body 1, the decorative board 3 is not damaged.

On the other hand, since the metal frame 6 is fastened parallel to the front surface of the front frame body 1 with the decorative board 3 in between, the glass door 7 of the metal frame 6
The glass door 7 is opened and closed without the end edge 7A of the glass door 7 hitting the corner 6A of the metal frame 6.

In addition, in this example, the decorative board 3 is composed of a single board, and the windows 4 and escape holes 5 to 5 of the decorative board 3 can be punched out at the same time by punching and forming with a press. Since it is easy to manufacture and is made of a single plate, it not only simplifies the work of adhering to the front frame main body 1, but also has a favorable appearance.

As explained above, in the present invention, the window of the decorative board is opened to approximately the same size as the square window hole of the front frame body, so the window of the decorative board is sandwiched between the windows and the window hole of the front frame body. can be fastened in parallel without interfering with the opening and closing of the pure glass door.

In particular, the present invention has a notch-shaped escape hole that corresponds to the metal fastening screw on the window peripheral edge of the decorative board, so the metal frame can be tightened to the front frame body with the decorative board in between. When doing so, the decorative board will not be damaged by the screws used to tighten the metal frame.

Therefore, the present invention can be said to be an extremely practical and desirable front frame for a pachinko machine.
