Description

[Detailed description of the invention] (Industrial application field) The invention comprises a board that supports a game board on which a game section is formed from below, and a launch rail that launches a ball toward the game section is detachable. This invention relates to a launching rail mounting device for a pachinko machine that is fixed to a pachinko machine.

(Prior art and its problems) The firing rail allows the ball to wait in an appropriate stationary state at its rear end, and also directs the ball fired by the firing section of the firing device to the game section of the game board. It has a function that allows the ball to be launched in an ideal flight condition.

If there is any deviation or distortion in the standby position or standby state, the point of impact of the firing section will deviate from the intended area of the ball, and the shot ball will not be able to travel straight. For example, if the ball is hit to the left or right of the intended area, the ball will fly sideways and travel in a zigzag pattern while alternately colliding with the mounting board surface, the game board surface, and the front glass. It turns into a ball or breaks glass.

Furthermore, if a part of the ball is hit that is above or below the intended part, the ball will be launched in a dynamic manner, and most of the balls will turn out to be ball balls.

In particular, when the game content is developing in the player's favor, for example, during a special prize mode where the probability of winning is particularly high, there may be frequent occurrences of foul balls, or the player may not be able to hit the ball exactly as he or she intended. Being unable to concentrate not only harms the interests of players, but also increases discomfort and causes players to lose interest in the pachinko game itself, which is a big negative for the industry.

Therefore, this type of launch rail must be installed with special care, and every precaution must be taken to prevent any deviation or distortion from occurring in the installed state.

However, since the current ball launcher has a performance of 100 balls per minute, it is easy for ball buildup to adhere to the launch rail, and this buildup can cause the above-mentioned problems in the ball's travel. will occur.

For this reason, in pachinko parlors, it is essential to wipe off ball stains from the firing rails every day after closing.

However, external forces applied during this daily wiping also tend to cause misalignment and distortion of the firing rail.

A misaligned firing rail must be corrected and re-fixed, but as in the past, the more firmly it is fixed with screws, etc., the more difficult it is to remove it. There are also cases where the next screw-in position cannot be corrected because it is obstructed by the screw hole.

Also, once the launch rail becomes distorted, there is no other choice but to replace it.
He was forced to do difficult work.

The present invention was made with the aim of solving this problem.

(Purpose of the invention and means for solving the problem)
A launch rail 10 that launches a ball toward the game section 51, and includes a base plate 30 that supports a base plate 30 from below.
In the launch rail mounting device for a pachinko machine, in which the launch rail 10 is fixed in a detachable manner, the front surface of the board 30 has at least two or more locations along the longitudinal direction of the launch rail 10 fixed to the front surface. A positioning member 31 is provided to determine the fixed position of the rail 10, and an engaging portion 32 is provided, and the launching rail 10 is provided with a launching guide groove 14 that guides the ball to the rail surface 11 over the entire length in the longitudinal direction. At the same time, a stabilizing contact surface is formed which is brought into contact with the mounting hole 16 opened to correspond to the engaging portion 32 and the front surface of the board expanded with the mounting hole 16 approximately in the center. The mounting portion 15 includes a shaft 21 inserted through the mounting portion 15 and a fitting hole 17 into which the positioning member 31 is fitted.
1, and a locking part 2 provided at the rear end of the shaft 21 and engaging with the engaging part 32.
2, the fitting hole 17 of the launch rail 10 is fitted into the positioning member 31 of the board 30, and the locking part 22 of the mounting member 20 is connected to the engaging part 32 of the board 30. , the locking portion 22 and the engaging portion 32 are brought into a locked state by a rotational operation of the operating portion 24, and the firing rail 10 is detachably fixed to the front side of the board 30. It is characterized by

(Function) When attaching to the board, first, the firing rail is pushed in so that the fitting hole of the firing rail fits into the positioning member of the board.

Then, the locking portion of the board and the mounting hole of the firing rail align with each other.

Next, insert the shaft of the mounting member into the matching engagement part and mounting hole, and twist the operation part of the mounting member by hand.The locking part of the mounting member engages with the back surface of the board, and the shaft The locking parts and the operating part at both ends of the board squeeze the side surface of the board and the launch rail, and the stabilizing abutment surface of the mounting part provided on the launch rail, thereby fixing the launch rail in close contact with the board more stably. .

On the other hand, when removing it, twist the operation part in the opposite direction by hand to disengage the locking part from the back of the board, and then pull the mounting member in the axial direction. Then, the engaging portion is pulled out, and the firing rail is released from being fixed to the base plate.

Moreover, since the launch guide groove for guiding the batted ball is formed on the rail surface of the launch rail over its entire length, the traveling state of the batted ball can be controlled more efficiently.

(Example) Hereinafter, the present invention will be explained based on examples.

In FIG. 1, the reference numeral 10 in the figure indicates the gaming section 51.
This is the launch rail that launches the ball toward the target.

This launch rail 10, as shown in FIG.
Launching rod 5 as the launching part of the projectile device that launches the ball
0 and the FAR ball, that is, the game section 51 formed in the area surrounded by the guide rail 52 of the game board 53.
without reaching the guide rail 5 on the launch rail 10 side.
It is attached to the front part of the base plate 20 so as to be located between the ball recovery gutter 40 that guides the ball (Fuar ball) that flows down the ball to the ball storage tray 59. The ball is guided to be launched toward a guide rail 52 that guides the ball to the gaming section 51 while regulating the direction of the ball, its rotation, and other traveling conditions.

The launching rail 10 shown in FIG.
1 and a reinforcing member 12 for reinforcing the structure.

The rail main body 11 is made by leaving the central part of a long belt-shaped metal material, such as a stainless steel plate, in the shape of a belt, and bending both sides 13, 13 of the central part downward at approximately right angles to form the cross section into a substantially shape. be.

The rail body 11 is provided with a launch guide groove 14 for guiding the traveling hit ball in the correct direction over the entire length in the longitudinal direction of the rail surface on which the hit ball travels.

The launch guide groove 14 preferably has a groove-like structure that supports the lower part of the ball at two points in a well-balanced manner.

In this example, the groove has a V-shaped cross section, but
However, the present invention is not limited to this, and for example, only the center portion may be formed into a V-shaped or U-shaped cross section, leaving flat portions on both sides of the rail surface.

Note that the above-mentioned side portions 13, 13 function to support this rail surface and maintain its shape.

Further, the rail surface of the rail body 11 is formed into a curved surface that gradually curves from the rear end side, that is, the firing rod 50 side, to the tip side, that is, the guide rail 52 side, in order to smoothly transfer the hit ball to the guide rail 52. .

This bending is performed, for example, so that the bending of the guide rail 52 smoothly matches the curve drawn by natural extension.

The rail main body may be bent in an arc shape or a bow shape over the entire length of the rail, or only a portion on the guide rail 52 side may be formed in an arc shape or a bow shape. In addition, when bending the entire length of the rail body, it is best to make it into an arc with a radius of about 2000 mm.

In this way, by forming the rail surface of the rail body 11 into a curved surface, the traveling hit ball can be prevented from lifting off the rail surface and will be in good contact with the rail surface, so that the controller using the rail surface and the launch guide groove 14 can be more easily controlled. The ball can be reliably hit, the ball can be stably fired, the direction of the ball can be reliably directed, and defective shots such as uneven flight can be eliminated.

The reinforcing member 12 is made of synthetic resin or hard rubber, and is formed on the lower surface of the rail body and on both sides 1.
It is formed in the inside of the rail body 11 composed of 3 and 13 so as to be integrated with the rail body 11.

In the embodiment, the reinforcing member 12 is filled inside the rail main body 11 over the entire length thereof.
It may be filled in one section in the length direction.

Further, the firing guide groove 1 formed in the rail body 11
Depending on the cross-sectional shape of the rail body 11
The reinforcing member 12 may be assembled so as to provide a gap between the lower surface of the reinforcing member 12 and the reinforcing member 12 . However, even in this case, it is best from the point of view of the reinforcing effect to form the reinforcing member 12 so that the upper surface of the reinforcing member 12 comes into contact with a part of the lower surface of the rail body.

Note that the reinforcing member 12 of the embodiment has one side portion 13
It is integrated with the rail main body 11 with a screw screwed from the side toward the internal reinforcing member 12.

By forming the reinforcing member 12 integrally assembled with the rail body 11 in this manner, the rail body 11 can be made more robust, and the durability of the rail body 11 against external forces applied during cleaning can be improved. is increased, and distortion and deviation can be prevented.

The above launch rail 10 includes a board 30 which will be described later.
A fixing attachment portion 15 that comes into contact with is provided.

In the embodiment, a mounting portion 15 is integrally formed with the reinforcing member 12 of the launch rail 10 and has a stabilizing contact surface that extends into an ear shape and is brought into contact with the front surface of the board 30.

In this way, not only the side surface of the launch rail 10 on the board 30 side but also a part of the reinforcing member 12 is expanded and formed on the launch rail 10 that comes into contact with the front surface of the board 30 so that the launch rail 10 comes into contact with the board 30. By forming the surface, the launch rail 10 is brought into contact with the substrate 30 in a more stable manner than in the past.

This mounting portion 15 has a shaft 21 which is expanded to be located approximately in the center of the mounting portion 15, and a shaft 21 that is connected to a shaft 21 of a mounting member 20 (described later) and a rear end portion of the shaft 21.
A mounting hole 16 is drilled through which a locking portion 22 protruding in the diametrical direction passes.

Reference numeral 30 in the figure is a board to which the launch rail 10 is attached.

As shown in FIG. 5, this board 30 supports a game board 53 on which a game section 51 is formed from below.

As shown in FIG. 1, on the front side of the board 30,
Positioning members 31 for determining the fixing position of the launch rail 10 to the board 30 are provided at at least two locations along the longitudinal direction of the launch rail 10 fixed to the front surface.

The positioning members 31, 31 of the embodiment are the substrate 30
This is a substantially conical protrusion that protrudes from the front surface of the. Of course, on the firing rail 10 side, there are fitting holes 1 into which the protruding positioning members 31, 31 are fitted, in portions corresponding to these positioning members 31, 31.
7 and 17 are provided.

Further, the fitting holes 17, 17 are fitted into the positioning members 31, 31 on the board 30, so that when the firing rail 10 is brought into contact with the front surface of the board 30, the fitting holes 17, 17 are aligned with the mounting holes 16 of the mounting portion 15 of the firing rail 10. An engaging portion 32 is provided at a position where the engaging portion 32 is engaged.

The engaging portions 32, 32 of the embodiment are holes penetrating the substrate 30, and have the same shape as the mounting hole 16. These mounting holes 16, 16 and the engaging part 3
2 and 32 will be described later.

In Figures 3 and 4, the reference numeral 20 in the figures is
It is a mounting member.

The mounting member 20 is attached to the stacked firing rails 1
a shaft 21 having a length that can pass through the mounting hole 16 of 0 and the engaging portion 32 of the substrate 30; a locking portion 22 formed at the front end of the shaft 21 and protruding in the diametrical direction of the shaft 21; The shaft 21 is formed at the rear end of the shaft 21.
The locking portion 22 is used as a knob for turning by hand.
and an operating section 24 which is similarly formed to protrude in the diametrical direction of the shaft 21.

The operating section 24 of the embodiment includes a disk-shaped collar section 23 that extends from the outer periphery of the shaft 21 .

In addition, in the mounting member 20 of the embodiment, the locking part 22 is made to protrude from the peripheral surface of the tip end of the shaft 21 in the diametrical direction of the shaft 21, and the disc-shaped collar part 23 is attached to the rear end of the shaft 21. They are formed coaxially, the length of the locking part 22 is slightly shorter than the diameter of the flange 23, and the axial distance between the locking part 22 and the flange 23 is such that the firing rail 10 is in contact with the base plate 20. At this time, the depths of the mounting hole 16 and the fitting portion 32 are made to match. This mounting member 20 is integrally molded from a highly durable synthetic resin.

When the shaft 21 is rotated in the mounting direction, the surface of the locking portion 22 on the side of the flange 23 is attached to the back surface of the board 30.
In addition, the inclined surface 28 is formed with a groove 25 extending in the length direction of the locking portion 22.

This groove 25 has the effect of preventing the locking portion 22 from warping in the longitudinal direction and increasing the pressing force of the locking portion 22 against the back surface of the substrate 30.

On the other hand, a protrusion 33 that can be engaged with at least a portion of the groove 25 is formed on the back surface of the substrate 30, and the engagement between the groove 25 and the protrusion 33 causes the locking portion to be closed. 22 is eliminated, and the locking portion 22 locks with the board 30 with even greater reliability.

Note that the protrusion 33 is connected to the locking portion 22 that protrudes in both directions.
They may be arranged to correspond to each other.

Regarding the mounting hole 16 and the fitting part 32.

The mounting hole 16 of the launch rail 10 is connected to the mounting member 20.
The shaft 21 and the locking part 22 can pass through, and the collar part 23
is drilled in a shape that makes it impossible to pass through. Its shape is not limited to the hole shape shown in the example.

The mounting hole 16 of the embodiment has a circular hole through which the shaft 21 passes closely, and a part of the circular hole expanded in the diametrical direction to allow the locking part 22 to pass through. The span in the length direction is smaller than the diameter of the collar portion 23 and the same length as the span of the locking portion 22.

The shaft 21 and the circular hole are made to have almost the same diameter.
This is because the firing rail 10 can be positioned more reliably by the tight fit between the opening rail 1 and the circular hole.

In addition, a portion of the circular hole that is partially expanded is connected to the locking portion 22.
The reason why the length is set to be the same as the width of the mounting hole 16 is to prevent the mounting member 20 from falling off naturally when the mounting member 20 is fitted into the mounting hole 16.

In the embodiment, in order to more reliably prevent this natural falling off, a small protrusion 27 is provided at the tip of the locking part 22 to the extent that there is no problem in inserting and removing it from the mounting hole 16.

By configuring the mounting member 20 to prevent it from falling naturally from the mounting hole 16 in this way, the mounting member 20 as a single component can be handled as one with the firing rail at all times, making it easier for mounting work and parts management. It is convenient.

On the other hand, the fitting part 32 of the board 30 is connected to the mounting hole 1.
6, but the partially expanded portion for the locking portion 22 may be formed to be slightly larger so that the locking portion 22 can pass through it easily. However, the circular hole of the fitting part 32 must be connected to the shaft 21 in order to perform the positioning function.
It must be the same diameter as.

In the case of the embodiment, separately as a positioning means,
Since the positioning member 31 is provided on the substrate 30 side and the fitting hole 17 is provided on the launch rail 10 side, they do not necessarily have to have the same diameter.

In FIGS. 1 and 2, reference numeral 40 in the drawings indicates a Far ball collection gutter attached to the surface of the substrate 30.

The FAR ball recovery gutter 40 connects the tip of the launch rail 10 attached to the board 30 and the guide rail 52.
The socket 41 is placed between the starting end and the starting end.

By the way, the tip of the launch rail 10 faces the socket 41 of the FAR ball collection gutter 40, but conventionally, the FUARU ball traveling backwards along the guide rail 52 collides with the tip of the launch rail 10, causing A problem has been that the firing rail 10 is distorted or misaligned due to the impact.

In this embodiment, in order to solve this problem, a receiving piece 42 that receives the collision of the Fuar ball is provided at the tip of the reinforcing member 20 that constitutes the launch rail 10, and a part of the socket 41 of the Fuar ball recovery gutter 40 is provided. It was integrally formed to do so.

As a result, the rail main body 11 is protected from the impact of the FAR ball, and the receiving piece 42 can also be integrally molded with the reinforcing member 20 made of synthetic resin or hard rubber, which simplifies manufacturing and assembly work. become.

Further, the FAR ball collection gutter 40 of the embodiment collects prize balls that overflow from the rear inlet of the batted ball supply tray 54 and overflowing prize balls that accumulate near the outlet of the prize ball guide gutter 55 after the opening/closing panel is opened. It is integrally formed with a connecting gutter 56 leading to a ball storage tray 59.

This Far ball recovery gutter 40 has a notch 57 on one side that engages with the locking piece 34 provided on the surface of the board 30, and a screw fastening part 58 on the other side to lock the notch 57. Insert the board 3 into the piece 34, lock it on one side, and pass the screw through the screw stopper 58 on the other side.
It is attached to 0. Therefore, the installation of the Far ball collection gutter 40 and the connection gutter 56 can be easily performed in one operation.

(Effects of the invention) As described above, the present invention allows operation by fitting the fitting hole of the launch rail into the positioning member of the board, and engaging the locking part of the mounting member with the engaging part of the board. The locking part and the engaging part are locked by rotating the part, and the firing rail is removably fixed to the front side of the board, so tools such as screws and screwdrivers are not required. without using any
It can be easily and accurately installed and can be easily removed.

Therefore, when manufacturing a pachinko machine or at a game parlor, the firing rail can be quickly installed or replaced, and work efficiency can be further improved.

Particularly in game parlors, since the firing rail can be easily removed when cleaning the firing rail, the ball scale adhering to the firing rail can be completely wiped off, and defective firing such as uneven flying caused by the ball scale can be eliminated.

Further, according to the present invention, not only the side surface of the launch rail on the board side but also the stabilizing contact surface of the expanded mounting portion is in contact with the board. Therefore, the firing rail is brought into contact in a more stable manner than in the past.

Moreover, since the tightening force for fixing to the board is concentrated on the mounting part that is expanded from the launch rail, compared to the conventional method in which the tightening force acts directly on the launch rail body, the tightening force is applied to the launch rail by tightening. It is possible to avoid adverse effects such as distortion.

Furthermore, since the enlarged mounting hole is located approximately at the center of the mounting section, the mounting member can be fixed to the board so as to pass through approximately the center of the mounting section, reducing the tightening force. By concentrating on the central part of the attachment part, the launch rail can be more firmly fixed to the board.

In addition, in this invention, since the launch guide groove for guiding the batted ball is formed on the rail surface of the launch rail over the entire length in the longitudinal direction, the batted ball launched from there is effectively controlled and uneven. It is possible to significantly reduce the incidence of flying and flying balls.
