Description

  The present invention relates to a pachinko machine having an inner rail that is bent and attached in an arc shape on a game board to guide the out ball to the out ball outlet, and an out ball outlet fitting that covers the out ball outlet. It relates to the structure to be attached to.

On the game board of the pachinko machine, an arc-shaped outer rail is attached to guide the hit ball to the upper part, and it is circular so as to surround the game area where various winning devices, winning holes, etc. are provided. A curved inner rail is attached, and an out ball guided by the inner rail is discharged by an out ball outlet formed at the lower edge thereof.
The outer rail and the inner rail have been conventionally attached to the game board with nail pins as shown in Patent Documents 1 to 3 below.

  In addition, an out ball outlet fitting is nailed at the out ball outlet for protection, but conventionally, the inner rail and the out ball outlet fitting are separately attached to the game board by nail pins. That is, after the out ball outlet fitting is first attached to the game board by the nail pin, the inner rail is attached to the game board by the nail pin so as to cross the upper surface. For this reason, the number of assembling steps is increased and the cost is increased.

Further, in Patent Document 4 below, since the inner rail and the out ball outlet fitting are integrally formed, the attachment process can be simplified, but the inner rail and the out ball outlet fitting are integrally formed. Since a large press die is required, there is a risk that the cost is rather high.

  Therefore, it was considered to attach the inner rail and the out ball outlet fitting separately formed to the game board at the same time, but in order to attach them to the game board at the same time, attach a nail pin to the out ball outlet fitting. Even if it is inserted, the out ball outlet fitting is removed from the nail pin before it is attached to the game board surface, so that it is difficult to attach at the same time with the conventional structure.

  In addition, veneer boards are generally used for game boards, and rails and out-ball outlet fittings are made of stainless steel plates. Therefore, when disposing of used game boards, rails and out-ball outlet fittings are used for resource recycling. Although it was necessary to separate from the main body of the board, when the inner rail and the out-ball outlet fitting were separately attached, there was a drawback that it was troublesome to remove and the workability was poor.

  The present invention solves such problems and enables the inner rail and the out ball outlet fitting to be attached to and detached from the game board at the same time.

Therefore, the inner rail mounting structure of the pachinko machine according to the present invention is a structure in which the inner rail and the out ball outlet fitting are attached to the game board by the nail pin, and the nail pin having the head engaged with the inner rail is provided. Non-circular mounting holes into which the nail pins can be inserted are respectively formed near the both side edges of the out-ball outlet fittings, and the nail pins are formed in the middle portion in the longitudinal direction. When the inner rail is attached to the game board while being inserted into the mounting hole, the flange is brought into contact with the peripheral edge of the mounting hole by bending the inner rail so that the nail pin is attached to the mounting hole. It is characterized by not being removed from the hole.
In the inner rail mounting structure according to the present invention, the inner rail and the out ball outlet fitting are formed of the same kind of metal material.

  When attaching the inner rail to the game board, it can be attached at the same time without dropping the out ball outlet fitting. This reduces the number of assembly steps required and reduces costs. In addition, when the inner rail is removed, the out ball outlet fitting is also removed at the same time, so that the material separation work at the time of disposal becomes easy.

  Next, embodiments of the present invention will be described with reference to the drawings. FIG. 1 is a perspective view of an inner rail 10 and an out ball outlet fitting 20 according to the present invention. The inner rail 10 is formed by forming a slanted recess 11 for ball guidance by pressing a substantially central portion in the longitudinal direction of a flexible stainless steel plate, and engaging holes 12a to 12h at appropriate intervals on one side edge. The nail pins 13a to 13h are inserted into the respective engagement holes and bent into hair pins, whereby the heads of the respective nail pins are engaged with the inner rail 10. As shown in the enlarged view of FIG. 2, each nail pin is integrally formed with a flange 14 at a substantially middle portion in the longitudinal direction, and when the nail pin is inserted into the game board 30 by protruding the flange. It is intended to prevent it. In particular, a pair of nail pins 13d and 13e are engaged with the symmetrical positions on both sides of the inclined recess 11 of the inner rail 10.

  The out ball outlet fitting 20 is formed by press-molding a stainless steel plate like the inner rail 10, and 22 is a horizontally elongated hole-like opening located at the center of the out ball outlet fitting. A pair of substantially rectangular mounting holes 21 a and 21 b are opened near both side edges of the out-ball outlet fitting 20. The pair of mounting holes 21a and 21b are formed in a C shape when viewed from the front as shown in the front view of FIG. For this reason, when the nail pins 13d and 13e are inserted into the mounting holes 21a and 21b, the inner rail 10 is bent slightly upward so that the flanges 14 of the both nail pins 13d and 13e are connected to the mounting holes 21a and 21b. Similarly, the cross-sectional shape of the nail pins 13d and 13e is matched with the substantially rectangular shape of the mounting holes 21a and 21b so that the nail pins 13d and 13e can be inserted into the mounting holes 21a and 21b. To. FIG. 4 shows a state in which the nail pins 13d and 13e are inserted into the mounting holes 21a and 21b.

  On the other hand, as shown in FIG. 5, stop holes 31 a to 31 h for attaching the inner rail 10 are formed in advance on the arc-shaped locus 32 in the game board 30. Reference numeral 33 denotes a notch formed in the lower portion of the game board 30 for discharging the out ball to the rear, and 34 and 35 are openings for attaching a winning device, a symbol variation display device and the like.

  Then, as shown in FIG. 5, the inner rail 10 is bent in a mounting posture (bent downward) in a state where the nail pins 13d and 13e are inserted into the mounting holes 21a and 21b. As a result, the nail pins 13d and 13e rotate slightly relative to the out-ball outlet fitting 20, so that the flanges 14 of the nail pins 13d and 13e are attached to the mounting as shown in FIG. The nail pins 13d and 13e come into contact with the peripheral portions of the holes 21a and 21b and are suspended without being removed from the mounting holes 21a and 21b. Therefore, in this state, the nail pins 13a to 13h are stopped by pressing the inner rail 10 with the tips of the nail pins 13a to 13h facing the stop holes 31a to 31h formed in the game board 30 in advance. The inner rail 10 and the out ball outlet fitting 20 are attached at the same time by being inserted into the holes 31a to 31h. In this way, the inner ball 10 is bent in the attachment posture, so that the out ball outlet fitting 20 that has passed through the nail pins 13d and 13e cannot be removed, so the inner rail 10 and the out ball outlet fitting 20 are attached to the game board 30. Can be attached simultaneously in one step.

  FIG. 7 shows the game board 30 to which the inner rail 10 and the out ball outlet fitting 20 are attached in this manner. In the figure, reference numeral 40 denotes an outer rail attached to the outside of the inner rail 10 for guiding a hit ball. 8 is a cross-sectional view taken along the line BB of FIG. 8, and FIG. 9 is a cross-sectional view taken along the line CC of FIG. 8. As shown in the figure, the mounting holes 21a and 21b and the nail are attached in this attached state. The pins 13d and 13e have a twisted relationship with the flange portion 14.

  Therefore, when the game board 30 is to be discarded, if the inner rail 10 is pulled and the nail pins 13a to 13h are pulled out from the stop holes 31a to 31h, the flange portions 14 of the nail pins 13d and 13e are out-ball outlet fitting 20 The out-ball outlet fitting 20 can be removed at the same time because it abuts against the peripheral edges of the mounting holes 21a and 21b. For this reason, if the inner rail 10 and the out ball outlet fitting 20 are formed from the same kind of metal material, they are separated from the game board 30 at the same time, and reuse as resources becomes easy.

  In this embodiment, a pair of rectangular attachment holes 21a and 21b are formed in the out ball outlet fitting 20. However, the shape of the attachment holes is such that the nail pins 13d and 13e are deformed when the inner rail 10 is bent in a mounting posture. Since the flange portion 14 can be brought into contact with each other, it may be non-circular and may not necessarily be formed in a rectangular shape as in this embodiment, and is not necessarily formed in a C-shaped form. You don't have to.
