DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a guide rail mounting structure mounted on a game board of a pachinko machine.

[0002]

2. Description of the Related Art Conventionally, as is well known, a guide rail of this type of hit ball is formed of a band-shaped metal plate such as stainless steel.
The attachment is performed by inserting a split pin having a special structure into a small through hole formed at the rear end of the guide rail and driving the split pin into a game board.

Recently, a rail mounting surface is formed on a decorative frame mounted on a game board surface, and a guide rail is mounted on the rail mounting surface (for example, Japanese Utility Model Laid-Open No. 1-17387). reference).

[0004]

In the former of those described in the prior art, the guide rail having restoring elasticity must be nailed while being curved in an arc shape, so that the mounting operation is troublesome and difficult. There was a problem that advanced technology was required.

In the latter case, although the guide rail can be mounted relatively easily, since the guide rail is mounted in a state in which the entire guide rail is in close contact with the rail mounting surface, the deflection of the guide rail is completely reduced in the mounted state. There was a fatal problem that it was lost and a good ball flight could not be obtained. SUMMARY OF THE INVENTION The present invention has been made in view of the above-mentioned problems of the related art, and has as its object to facilitate installation work of a guide rail and to provide sufficient deflection of the guide rail in the mounted state. It is an object of the present invention to provide an installation structure of a guide rail in a pachinko machine which can be provided with the following.

[0006]

In order to achieve the above-mentioned object, a guide rail mounting structure in a pachinko machine according to the present invention has a rail mounting surface formed on a decorative frame mounted on a game board surface, and the rail mounting surface. A plurality of fitting recesses are formed at appropriate intervals, while a rail support is slidably mounted on the guide rail, and the rail support is fitted into the fitting recess, whereby the guide rail is On the rail mounting surface of the decorative frame.

[0007]

The rail support is attached to the guide rail, and the rail support is fitted into the fitting recess of the decorative frame. Thus, the rail support is fixedly held in the fitting recess, and the guide rail is mounted on the rail mounting surface of the decorative frame via the rail support.

[0008]

Embodiments will be described below with reference to the drawings. FIG. 1 is a front view of a pachinko machine, 1 is a front frame of the pachinko machine, and 2 is a game board mounted on a rear surface of the front frame 1. As shown in FIG. 2, an inner rail 3 is mounted in a circular shape at the center of the game board 2, and decorative frames 4 are mounted on both left and right sides so as to surround the inner rail 3.

The decorative frame 4 is formed of a synthetic resin into a plate having a required thickness, and has an arc-shaped rail mounting surface 5 formed on an inner peripheral surface thereof.
Are provided with a plurality of fitting recesses 6 at predetermined intervals. As shown in FIGS. 3 and 4, the fitting recess 6 is formed in a flat U-shape that is open at the rail mounting surface 5, and is formed on both inner side walls 7, 7 of the fitting recess 6 in parallel with the rail mounting surface 5. The ridges 8, 8 are provided to face each other.

Reference numeral 9 denotes a rail support, which comprises a support member 10 formed by bending a metal plate into a C-shape as shown in FIGS. 6 and 7, and a fixing member 11 formed of a synthetic resin into a column. The support member 10 has locking edges 13, 13 for locking both edges of the guide rail 12 at both bent ends, and a through hole 14 substantially at the center of the vertical surface 10 a. Also,
The width of the support member 10 is selected so as to coincide with the fitting recess 6.

On the other hand, the fixing member 11 has a cylindrical projection 15 projecting from the rear surface thereof protruding rearward from the through hole 14 of the supporting member 10 and has a rectangular plate-like body 1 at its protruding end.
6 is fixed by screws 17 so that the supporting member 10
And the fixing member 11 are integrally connected to each other to form the rail support 9.

The supporting members 10 and the fixing member 11 are connected to the locking edges 13, 13 of the supporting member 10 and the front surface of the fixing member 11 in a state where the rear surface of the fixing member 11 is in contact with the vertical surface 10a of the supporting member 10. A gap 18 substantially equal to the thickness of the guide rail 12 is formed between the support member 10 and the vertical surface 10a of the support member 10.
The shape is selected such that a gap 19 is formed between the ridges 8 and 8 of the fitting concave portion 6 between the metal plate and the plate-like body 16.

In the embodiment described above, the guide rail 12 is mounted by first engaging the locking edges 13
The guide rail 1 is inserted into a gap 18 between
2, the rail support 9 is mounted on the guide rail 12 (see FIG. 4). Next, the guide rail 12
Is fitted on the rail mounting surface 5 of the decorative frame 4 and the rail support 9 is slid to the position where the fitting concave portion 6 of the decorative frame 4 is formed and fitted into the fitting concave portion 6. At this time, the gap 19 between the vertical surface 10a of the support member 10 and the plate-like body 16 faces the projections 8, 8 of the fitting recess 6, and is pressed and inserted.
As a result, as shown in FIGS. 3 and 5, the rail support 9 is firmly supported by the fitting recess 6 of the decorative frame 4, and the guide rail 12 is easily attached to the rail mounting surface 5 of the decorative frame 4. Can be installed.

[0014]

As described above, the guide rail mounting structure of the pachinko machine of the present invention has a rail mounting surface formed on a decorative frame mounted on a game board surface and a fitting recess formed on the rail mounting surface. On the other hand, a rail support is slidably mounted on the guide rail, and the rail support is mounted on the rail mounting surface by fitting the rail support into a fitting recess of the decorative frame. Therefore, the guide rail can be easily and reliably attached by a simple operation.

Further, since the guide rail is only held by the rail holder, appropriate deflection can always be secured, and a good ball flight can be obtained.
