Abstract

PROBLEM TO BE SOLVED: To effectively prevent variations of ball entrance rates to winning ports and entering of a game ball into the inner depth part of an opening in a resin-made game board that are caused by large jump-up or other irregular action of game balls caused by high repulsion of game nails implanted in the game board.SOLUTION: A game machine includes: winning ports arranged in a game board surface; and route nail lines constituted by a plurality of route nails arranged to guide game balls flowing down on the game board surface to the winning ports. A buffer member for diminishing force of a game ball jumped upward at the route nails is arranged above the route nail lines at a predetermined interval from the route nail lines.

Description

  The present invention relates to a technique for effectively preventing a large jumping of a game ball caused by an increase in the repulsive force of a game nail implanted in a game board when a resin game board is employed.

In pachinko machines, various board parts such as a prize opening, windmill, variable display device, and lighting device are provided on the board surface of the game board in order to diversify the contents of the game, winning prizes during the game, and other situation changes The stage effect is enhanced by moving the movable panel surface parts in various directions.
For example, when a game ball wins a start winning opening provided on the game board, the symbols displayed on the liquid crystal screen of the variable display device in the game board start to fluctuate, and the symbols that have been stopped after a predetermined time have been determined in advance. When it becomes a jackpot symbol, it becomes a jackpot state, and the player can acquire a large number of balls. In such a gaming machine, various display effects are performed in order to enhance the interest of the game.

19 (a) and 19 (b) are a front view showing a state in which a game ball that has flowed down the game board surface is guided by the nail group and moves to the winning opening, and a perspective view seen from above. is there.
The game ball B launched from the game ball launching device rises along the introduction path 101 provided along the left peripheral edge of the game board 100 and flows down to the game area from the game ball introduction port at the upper left of the game board. Come on. A liquid crystal display device 106 is disposed in the opening 105 provided in the center of the game area, and a start winning opening (not shown) is disposed on the lower surface of the central portion of the lower edge of the opening. A windmill 110 is disposed on the lower left surface of the opening 105, and a plurality of game nails called road pegs 111 are planted in substantially a row between the windmill and a start winning opening (not shown). . The game ball that has fallen on the windmill 110 and rotated the windmill in the clockwise direction moves onto the road nail train 111A composed of the road nail 111 and moves on the road nail train toward the start winning opening.

By the way, since the conventional game board is composed of a plywood board, the game nail implanted in the game board can absorb and reduce the impact received from the game ball by the buffering action of the plywood board, and the game nail hits the game nail vigorously It was rare for the ball to jump up.
In recent years, game boards made of acrylic and other resin materials have begun to be used in place of veneer boards (Patent Documents 1, 2, and 3), but resin game boards are harder and less deformable than veneer boards, so they have a cushioning effect. Is significantly lower than the plywood board, and the game nail implanted in the resin game board cannot sufficiently absorb and mitigate the impact received from the game ball. For this reason, the game ball which hits the game nail vigorously has a strong tendency to jump up.
Accordingly, when the game board 100 shown in FIG. 19 is made of resin, the game ball B that has dropped from the windmill 110 onto the road nail 111 is likely to bounce as shown in the figure due to the repulsive force of the game nail. When the game ball bounces greatly, not only does the player feel uncomfortable, but there are also practical disadvantages such as the rate of entering the winning holes varying. For this reason, as the game progresses, there is a demand for not wanting the game ball to bounce on the road nail.

On the other hand, a partition plate 115 is arranged at a position along the lower edge of the opening 105 to prevent the game ball from entering the space between the lower edge of the opening and the liquid crystal display device 106 located behind the opening. However, the partition plate 115 is merely set low enough to cover the lower part of the display of the liquid crystal display device 106 so as not to hinder the visibility of the image. It is impossible to completely prevent the game ball from getting over the partition plate 115 and entering the space.
Since a movable accessory is often arranged in the space between the opening 105 and the liquid crystal display device 106, a game ball that has entered here may interfere with the operation of the movable accessory or cause a failure.
In addition, if the height of the game ball jumping on the road nail becomes large, a situation such as a bounce remaining just before the start prize opening, or the game ball cannot be decelerated, the rate of entry to the start prize opening It has also been found that the variation becomes large.
Furthermore, the game balls bounced on the pegs planted on the resin game board surface have a high moving speed even when they do not jump high, so the rate of entering the starting prize opening can be increased by repeating low bounce. There is a tendency to reduce significantly.

In this way, the change in behavior such as the jumping height (especially large and irregular bouncing) of the game balls on the nail row, the moving speed, etc. affects the winning rate at the starting winning opening. Although the player is the most watched target, if the game ball shows an unfamiliar behavior on the plywood board on the peg row, it causes anxiety to the player.
In particular, since the way the game balls bounce is not uniform due to the entanglement with the windmills arranged just before the road nail train, the size of the member that effectively suppresses the game balls jumping up in various modes is increased. It was difficult to design without
Specifically, it is also conceivable to arrange a bowl-like long member for suppressing and decelerating only irregular jumping of the game ball above these so as to cover the entire length of the nail train from the windmill. However, this is difficult to realize because it deteriorates the appearance and lowers the degree of freedom of layout of other adjacent panel components.

The game nails planted on the resin game board have a stronger repulsion than the game nails installed on the veneer game board, so that the game balls that fall on the game nails bounce up and bounce without slowing down. There is a tendency to move on the nail. When a game nail falls through a windmill on a road nail row planted along the lower edge of the opening provided in the game board and jumps greatly, it reaches the winning opening while repeating irregular bouncing. In other words, the game balls that have fallen on the road pegs show irregular behavior that would not be considered in the road pegs that are planted on the veneer game board. Invited, it becomes a factor to give great anxiety to the player. In addition, the game ball that has greatly jumped over the partition plate and enters the back side of the opening may cause various problems such as interference with other objects.
The present invention has been made in view of the above, and is caused by a large jump of a game ball generated due to a high repulsive force of a game nail implanted in a resin game board, and other irregular behaviors. A gaming machine having a configuration that effectively prevents variations in the rate of entering the winning holes and entering the inner depth of the opening of the game board is proposed.
Especially, due to the behavior of the windmill arranged upstream of the road nail row, the way the game balls bounce will vary, but the buffer member is placed so as to cover directly above the road nail row and rises beyond the allowable range I was able to cope with every way of coming. Since the momentum of the game ball is suppressed by contact with the buffer member, there is no irregular behavior downstream (immediately upstream of the winning opening).

In order to achieve the above object, a first aspect of the present invention is a road comprising a winning opening arranged on a game board surface and a plurality of pegs arranged for guiding a game ball flowing down the gaming board surface to the winning opening. A buffer member for reducing the momentum of a game ball bounced by the road nail row is provided above the road nail row at a predetermined distance from the nail row. To do.
In order to suppress irregular behaviors such as excessive jumping of game balls on the nail train, which causes the winning rate to be distributed to the winning holes arranged on the downstream side of the nail train, poor deceleration, etc. The cushioning member is arranged so as to reduce the momentum in contact with the game ball that rises above the allowable limit.
The invention according to claim 2 is characterized in that the buffer member is configured to be moved by being pressed by a game ball bounced by the road nail.
The buffer member may be fixedly arranged, but by being configured to move by being pressed by the game ball, the momentum of the game ball can be effectively absorbed and reduced.
The invention of claim 3 is characterized in that the buffer member is rotatably supported by a rotation shaft provided at an appropriate position of the buffer member.
The invention according to claim 4 is characterized in that the buffer member is configured to be displaced upward by being pressed by a game ball hitting the lower surface of the impact member.
The invention according to claim 5 is characterized in that a buffer portion for reducing the momentum of the game ball bounced upward from a windmill disposed upstream of the nail train is provided on the lower surface of the buffer member. .

In the present invention, the game ball generated due to the high repulsive force of the game nail implanted in the resin game board, and the rate of entrance to the winning opening due to other irregular behavior It is possible to effectively prevent variation and entry into the inner part of the opening of the game board.
Especially, due to the behavior of the windmill arranged upstream of the road nail row, there is a variation in how the game balls bounce, but the buffer members can cope with any way of splashing, and the momentum of the game balls is influenced by the buffer members Since it is suppressed, there is no irregular behavior downstream.

Hereinafter, the present invention will be described in detail with reference to embodiments shown in the drawings.
FIG. 1 is a front view of a pachinko gaming machine as an example of a gaming machine according to the present invention, and FIG. 2 is a front view showing a gaming board and various components mounted thereon.
A glass frame 2 supporting a glass plate is attached to the front side of the game board 1 so as to be openable and closable. Also, at the lower part of the game board 1, there are provided a tray part 3 for storing game balls and a launch lever 4 for launching game balls in the tray part. Further, a button switch for gaming machine, a purchase button for game balls, and a purchase cancel button (none of which are shown) are provided on the upper surface of the tray portion 3.
On the back side of the game board 1, a synthetic resin mechanism board (none of which is shown), which is assembled with back parts related to the progress and production of the game, such as a liquid crystal screen, main control board and sub-control board, can be freely opened and closed. Has been. Around the game area 1a of the game board 1, an outer rail R1 for guiding a game ball launched from the launching device by operating the launch lever 4 to the upper part of the game area 1a, or guiding it to the out port 8, and An inner rail R2 is provided.

A center member 5 having an open center is disposed in an opening 1b formed at a substantially central portion of the game board 1. A symbol display device 6 is disposed inside the center member 5 (at the back of the opening 1b). The symbol display device 6 is constituted by a liquid crystal display panel such as a liquid crystal display device, for example, and displays a special symbol image (not shown) in a normal operation state. In the so-called special game state, an effect image indicating the special game state is displayed.
A start winning port 9 for variably displaying a special symbol of the symbol display device 6 is arranged at the center lower part of the center member 5, and a special symbol of the symbol display device 6 is variably displayed immediately below the start winning port 9. A variable winning device 11 is provided. Further, on the left side of the symbol display device 6, a gate 12 for operating a normal symbol displayed on the normal symbol display device 16 is provided. Further, on the right side of the variable winning device 11, there is provided a big winning opening 13 having an open / close door that is opened in a big hit state which is one of the special gaming states.
The variable winning device 11 includes an electric tulip having a pair of left and right open / close claws (movable pieces) for variably displaying the symbol display device 6.

Further, the game board 1 is provided with a normal winning port 14, an out port 8, and the like, and a windmill 15 and a large number of game nails 20 are projected. The game nail 20 slows down the falling speed of the game ball and changes the falling direction in a complicated manner to enhance the interest in game progression.
Between the windmill 15 and the start winning opening 9, a plurality of game nails 20 called road nails 21 are planted in a line obliquely downward to the right. The game ball that has fallen on the windmill 15 and rotated the windmill in the clockwise direction moves onto the road nail train 21 </ b> A composed of a plurality of road nails 21, and moves on the road nail train toward the start winning opening 9. . In addition, a partition plate 17 for preventing the game ball from jumping into the space between the opening and the symbol display device 6 is disposed at the lower edge of the opening 1b.
The normal symbol displayed on the normal symbol display device 16 can variably display one or a plurality of symbols, and the symbol is a random number on condition that the gate 12 as a normal symbol start port detects a game ball. It is variable and stopped for a predetermined time by control or the like.

  The special symbol displayed on the symbol display device 6 is configured to be in a big hit state when the stop symbol is a predetermined symbol combination, for example, the same symbol combination. In addition, the special symbol is scrolled by random number control etc. on the condition that the game ball is detected at the lower start port (not shown) where the game ball is guided by the opening operation of the electric tulip of the variable winning device, etc. It fluctuates (varies) for a predetermined time with a predetermined fluctuation pattern and stops at a symbol. At that time, when two stop symbols become the same on the active line, a reach state occurs, and in this reach state, the last stop symbol on the active line is already stopped. A jackpot condition occurs when they are the same. In addition, as a special symbol, a numerical symbol, an alphabet symbol, a character symbol, etc. can be used.

FIG. 3 is an enlarged view showing a configuration of a main part of the gaming machine according to the present invention, and FIG. 4 is a front view showing a state in which the buffer member is buffering the game ball jumping on the nail train. FIG. 5 is an upper perspective view of the same portion as FIG. 4.
The game board 1 according to the present example is made of acrylic or other resin, and the game nail 20 is firmly planted in a nail hole formed in advance on the game board surface and has a strong repulsive force. For this reason, the jump distance when the game ball falls and jumps on the game nail 20 and the rebound speed are the jump distance when the game ball falls with the same momentum as the game nail installed on the veneer game board. , And significantly larger (for example, 1.5 times or more) than the rebound speed.
The situation is the same for the road nail 21, and the game ball that has flowed down the game board surface and dropped onto the road nail row 21 </ b> A via the windmill 15 greatly jumps in the upper right direction and passes the partition plate 17 to the far side. The probability of getting into is increased. Alternatively, it tends to move toward the starting winning opening at a high speed on the nail train, and the pitch rate tends to decrease.
The characteristic configuration of the present invention is that the wind turbine 15 and the road nail row 21A are respectively separated from the road nail row by a predetermined appropriate distance G1 and G2, respectively, and the wind turbine 15 and the road nail 21 are respectively slanted upward. The buffer member 30 for reducing the momentum of the game ball B is disposed.

Since the buffer member 30 protrudes so that the lower surface of the bottom plate 30 </ b> A overhangs above the nail, it is possible to reduce the momentum by receiving the jumped game ball by the lower surface of the bottom plate. Further, the buffer member 30 does not need to be provided over the entire length of the road nail row, and it is sufficient if it is disposed above the windmill and a part of the upstream side of the road nail row.
The buffer member 30 is provided with buffer portions 31 and 32 on the lower surface of the bottom plate 30A for receiving the game balls jumped up by the road nail row 21A and reducing the momentum. That is, a lateral length L1 suitable for catching a game ball jumped in a diagonally upper right direction on the lower surface of the bottom plate of the buffer member 30 by being struck by a windmill rotating against a blade of the windmill 15 or rotating clockwise. A first buffer part (upstream buffer part) 31 having a front-rear width W1 and a second buffer part (downstream buffer part) extending by a predetermined length L2 from the right end of the first buffer part 31 to the downstream side The second buffer portion 32 receives the game ball bounced upward in the road nail row 21A and prevents it from entering the back side beyond the partition plate 17 or the like. The front-rear width W2 and the lateral length L2 are set so as to reduce the moving speed.

The lateral length L2 of the second buffer portion 32 is such that the game balls B cross the partition plate 17 as the game balls B bounce a plurality of times zigzag alternately between the nail train 21A and the bottom plate bottom surface of the buffer members. The length is set to a length that is necessary and sufficient to attenuate the ball so that there is no fear or the game ball is sufficiently decelerated in front of the start winning opening. In this example, the front-rear width W1 of the first buffer part 31 and the front-rear width W2 of the second buffer part 32 are substantially equal. It is sufficient that the lateral length L1 of the first buffer portion 31 is about 1 to 2 cm, and the lateral length L2 of the second buffer portion 32 is about 3 to 5 cm. Therefore, the buffer member 30 becomes a small member and can be installed using a small space on the nail train. By configuring the buffer member 30 from a resin material, the weight can be reduced.
The gap G1 between the first buffer portion 31 and the windmill (blade) provided on the bottom plate lower surface of the bottom plate 30A of the buffer member, and the gap G2 between the second buffer portion 32 and the road nail row 21A are the blades of the windmill 15. The normal height of the game ball jumping upward and the normal height of the game ball falling directly on the road nail row via the windmill is set higher than the normal height. Set so as not to interfere. This is because the game ball that jumps up at the normal level does not jump up beyond the partition plate 17 and does not need to hinder its behavior.

On the other hand, if there is a possibility that a game ball bouncing high with the blades of the windmill 15 or a game ball bouncing directly from the windmill onto the road nail row and crosses the partition plate 17, the height exceeds these. Therefore, the height of the lower surface of the bottom plate of the buffer member 30 is set to a predetermined value to prevent further increase.
That is, the height position of the bottom surface of the bottom plate of the buffer member 30 is set so that the game ball that jumps directly from the windmill and the game ball that jumps from the nail train can be pressed down before crossing the partition plate 17. On the other hand, if the gaps G1 and G2 between the lower surface of the bottom plate of the buffer member 30, the windmill, and the nail train are too short, the number of bouncing increases abnormally and the appearance deteriorates, but the damping effect decreases. It is necessary to set the above distance appropriately. Further, even if the game ball does not jump up so high as to exceed the partition plate 17, if the movement speed is likely to be too fast if it is not regulated by the buffer member, the jump of such a game ball is regulated to some extent. Therefore, the intervals G1 and G2 need to be set appropriately in consideration of such various conditions.
Since the lower surface of the bottom plate comes into contact with the game ball that jumps up from the windmill or the nail row, the buffer member 30 functions as a buffer portion that reduces the momentum (prevents further rising), so the upper portion other than the bottom surface of the bottom plate The shape and structure of can be variously modified. In addition, at least, a bottom plate serving as a buffer portion and an attachment member for attaching the bottom plate to a game board surface or the like are sufficient as a buffer member.

Next, FIGS. 6A, 6 </ b> B, and 6 </ b> C are front views comparing various buffer effects by variously changing the height position of the buffer member.
6A is equivalent to the height position of the buffer member shown in FIGS. 3 to 5, and FIG. 6B is a distance d1 larger than the case of FIG. (C) shows a state where the distance G2 between the nail train and the buffer member is made smaller by the distance d2 than in the case (a). FIGS. 7A, 7B and 7C are longitudinal sectional views corresponding to FIGS. 6A, 6B and 6C.
When the game ball B that has flowed down from the same direction on the game board surface bounces upward with the blades 15a of the windmill 15, the subsequent behavior varies depending on the height position of the buffer member 30. .

  In the case of FIGS. 6A and 7A, the gap G2 between the bottom plate lower surface (second buffer portion 32) of the buffer member 30 and the road nail row 21A is set substantially equal to the diameter of the windmill 15. The game ball bounced at the first buffer portion 31 falls to the right and obliquely downward and repeats bouncing between the nail train 21A and the second buffer portion 32, and the momentum is sufficiently reduced. Then, it moves toward the start winning opening 9 located on the downstream side. As long as the game ball B is located between the second buffer portion 32 and the road nail row 21A located below the second buffer portion 32, the game ball B is obstructed by the second buffer portion 32 protruding in a bowl shape, and the partition plate 17 No more intrusion into the back beyond. Further, when the game ball reaches the downstream side where the second buffer portion 32 does not exist, the momentum has already been sufficiently reduced, so there is no possibility of entering the back side beyond the partition plate 17. Even if the game ball does not jump so much as to exceed the partition plate 17, the second buffer is used even when there is a possibility that the game ball moves at a high speed toward the start winning opening if it does not buffer. The momentum can be reduced and reduced by the portion 32.

Next, in the case of FIG. 6B and FIG. 7B, the distance G2 between the bottom surface of the bottom plate of the buffer member 30 and the nail row is wider by the distance d1 than in the case of FIG. Therefore, the number of bounces that the game ball repeats between the bottom plate bottom surface of the buffer portion 32 and the nail row is smaller than in the case of (a), and the game ball has reached the downstream side where the second buffer portion 32 does not exist. At that time, the momentum is sufficiently diminished, so there is no risk of entering the back side beyond the partition plate 17. Further, the vehicle is sufficiently decelerated in front of the start winning opening.
Next, in the case of FIGS. 6 (c) and 7 (c), the distance G2 between the bottom plate bottom surface of the buffer member 30 and the road nail row 21A is narrower by the distance d2 than in the case of (a). A game ball that bounces right upward with the blades of the windmill, reflects off the first buffer portion 31 and falls right diagonally downward, repeatedly bounces between the nail train 21A and the second buffer portion 32 many times. Then move downstream. In this case, the effect of reducing the momentum of the game ball is inferior to that of the embodiment of FIGS. 6 (a) and 6 (b), and the game ball with the momentum not sufficiently reduced is vigorously moved to the downstream side of the nail train. Will do. In this case, there is a possibility that the winning rate to the start winning opening varies.
Therefore, it is preferable to set the gap G2 to the extent shown in FIGS. 6 (a) and 6 (b).

Thus, even if the height position of the buffer member is changed variously, a sufficient buffer effect can be exhibited. For this reason, how to set the interval (the height of the buffer member) G2 between the buffer member 30 and the road nail row 21A is arbitrarily determined depending on the concept in production and the layout with the peripheral board parts. The range of height position selection can be widened.
In the above-described embodiment, the case where the game ball bounced upward by the windmill blade 15a hits the buffer portion 31 and then falls on the road nail train 21A is exemplified. However, the game ball directly onto the road nail from the clockwise windmill. The buffer member functions in the same manner even when the water drops and jumps up.
Since the small and lightweight shock absorbing member 30 does not take up a large space for mounting, it can be fixed with screws on the game board surface, board surface parts, or any other narrow part. In addition, since there is no particularity in the attachment part and the attachment method, the attachment part can be easily selected and simple attachment is possible.
In the above embodiment, the buffer member is rigidly fixed to the game board surface and other parts by screwing or the like. However, the buffer member is vertically and horizontally and in any other direction due to the stress caused by the collision with the game ball. You may comprise so that it may displace and it may become easy to reduce the momentum of a game ball further.

FIG. 8 is a front view of an essential part showing a configuration example in which the cushioning member is displaceably supported, FIG. 9 is a perspective view of the portion of FIG. 8 as viewed from above, and FIGS. 10 (a) and 10 (b) are diagrams. 8 is a YY longitudinal sectional view of FIG.
The buffer member 30 is fixed with screws using mounting holes formed in the game board, board surface components, etc., but is configured to displace the buffer member by providing a clearance (backlash) between the mounting holes and the screws. be able to. In other words, the buffering performance can be enhanced by configuring the buffer member 30 so as to be displaced according to the force received from the game ball, rather than being rigidly fixed to the mounting hole. That is, the buffer member according to the present example is configured to move in a direction to reduce the momentum of the game ball when pressed by the game ball bounced by a windmill or a road nail, and to return to the original position after the movement. Yes.

FIG. 10A shows a space between two mounting holes 40 as round holes provided in the game board 1 and screws 42 screwed into the screw holes 34a of the two boss portions 34 of the buffer member 30, respectively. A clearance (back) C is formed on the surface. Normally, each member maintains the state shown in the figure by the pressure contact force between the washer 43 and the back of the game board by fastening the screw 42. On the other hand, when the game ball B collides with the lower surface of the bottom surface of the buffer member 30 and receives an upward force, the screw 42 and the boss 34 are deformed upward as shown in FIG. To do. For this reason, the momentum of the game ball can be reduced. If the washer 43 is a rubber washer, the buffer member can be displaced more easily and flexibly.
In this example, the direction in which the buffer member 30 is displaced is not uniquely regulated, and can be freely displaced in various directions according to the difference in the direction in which the game ball collides with the bottom surface of the buffer member. FIG. 13A shows a state in which the cushioning member moves in all directions of 360 degrees in the cushioning member mounting structure in the present embodiment.

  In the case where the buffer member is rigidly fixed at the position indicated by the solid line in FIGS. 8 and 9, the game ball that has collided with the first buffer part 31 via the windmill 15 follows the zigzag path indicated by the solid line. The bounce is repeated and moves to the downstream side. However, when the buffer member 30 is configured to be displaceable in the vertical direction, the game ball that collides with the first buffer portion 31 is greatly attenuated via the path indicated by the broken line. While moving, go downstream. In the case of the present embodiment, since the buffer member 30 is displaced upward by receiving the force when the game ball collides with the first buffer portion 31, the momentum of the game ball is rapidly reduced, and the number of bounds is small. Then, the buffer member is pulled downstream. For this reason, the lateral length of the buffer member 30 can be further shortened to reduce the size and weight.

  Next, FIG. 11 is a front view showing a configuration of a buffer member according to another embodiment of the present invention. In this embodiment, the inside of a vertically long slot-like mounting hole 40 provided in a game board or a board surface component is shown. The boss 34 protruding from the back surface of the cushioning member is supported so as to move in the vertical direction. For this reason, the buffer member 30 receives the force from the game ball colliding with the bottom surface of the bottom plate and is displaced upward (vertical direction) as shown in FIG. 13B, thereby rapidly reducing the momentum of the game ball. , It can be made to come out downstream of the buffer member with a small number of bounces. It is preferable that the number of game balls to be bound is small because anxiety given to the player can be reduced in appearance as compared with the case where the number of bounces is large. Moreover, the effect which can shorten the horizontal direction length of the buffer member 30 and can be reduced in size and weight can also be expected.

Next, FIG. 12 is a front view showing the configuration of the buffer member according to another embodiment of the present invention. In this embodiment, the inside of the oblique long hole-like mounting hole 40 provided in the game board or the board surface component is shown. The boss 34 protruding from the back surface of the cushioning member is supported so as to move in the vertical direction. For this reason, the buffer member 30 receives a force from the game ball colliding with the bottom surface of the bottom plate and is displaced obliquely to the upper right as shown in FIG. 13C, rapidly reducing the momentum of the game ball and reducing the bounce The buffer member can be removed downstream by a number. For this reason, the lateral length of the buffer member 30 can be further shortened to reduce the size and weight.
Since the movement direction of the buffer member in this example is along the direction in which the game ball collides with the lower surface of the buffer member, the buffer effect can be more effectively exhibited.

In each of the above embodiments, the bottom plate lower surface (second buffer portion 32) of the buffer member 30 in the initial state where the game ball does not collide is substantially parallel to the direction in which the nail row extends. The buffering effect can be enhanced by making the columns non-parallel.
First, FIG. 14A shows a configuration example in which the bottom surface of the bottom plate of the buffer member is inclined upward as it goes downstream.
When the buffer member is fixed to the game board surface or the like as shown in FIGS. 4 and 5, the buffer member lower surface (second buffer portion 32) is set at a predetermined angle θ1 with respect to a line l1 parallel to the direction in which the nail train extends. By tilting upward, the distance between the nail train and the lower surface of the buffer member expands toward the downstream. For this reason, compared with the case where the distance between the nail row and the lower surface of the buffer member is constant, the distance that the game ball moves between the nail row and the lower surface of the buffer member becomes longer as it goes downstream. Only the damping effect increases. For this reason, the lateral length of the buffer member can be shortened to reduce the size and weight.

In addition, a fulcrum for rotating the buffer member 30 is provided at a position indicated by reference numeral 50 in FIG. 14A, and the downstream portion (second buffer portion 32) of the buffer member 30 rotates up and down around the fulcrum 50. You may comprise so that it may move. In this case, the lower surface of the buffer member may be configured to rotate upward by an angle θ1 from a descending position substantially parallel to the nail row, or from an upwardly inclined position indicated by a solid line in FIG. Further, it may be configured to rotate upward.
In this way, by configuring the buffer member 30 to move up and down by the impact from the game ball, the buffer effect can be further enhanced.

Next, FIG. 14B shows a configuration example in which the bottom surface of the bottom plate of the buffer member is inclined downward toward the downstream.
When the buffer member is fixed as shown in FIGS. 4 and 5, the lower surface of the buffer member (second buffer portion 32) is inclined downward by a predetermined angle θ2 with respect to the line l1 parallel to the extending direction of the nail train. As a result, the distance between the nail train and the lower surface of the buffer member expands toward the downstream. For this reason, the number of times that the game ball bounces between the nail row and the lower surface of the buffer member is increased as compared with the case where the distance between the road nail row and the lower surface of the buffer member is constant. be able to. For this reason, the lateral length of the buffer member can be shortened to reduce the size and weight. Although there is a demerit in appearance that increases the number of times of bouncing, it is a configuration that can be used practically.
In addition, a fulcrum for rotating the buffer member 30 is provided at a position indicated by reference numeral 50 in FIG. 14B, and the downstream portion (second buffer portion 32) of the buffer member 30 rotates up and down around the fulcrum 50. You may comprise so that it may move. In this case, the lower surface of the buffer member is configured to rotate from the descending inclination posture indicated by the solid line to a position rotated upward by an angle θ2.
Thus, the buffering effect can be further enhanced by configuring the buffer member 30 so as to rotate in the vertical direction by the impact from the game ball.

Next, FIGS. 15A and 15B are front views showing another configuration example of the buffer member according to the present invention. In this embodiment, the front surface of the bottom surface of the buffer member has a corrugated shape (arc-shaped unevenness). (Consecutive state), the buffer effect for reducing the momentum of the game ball is further enhanced.
First, in FIG. 15A, the second buffer portion 32 has an arc-shaped unevenness 55, and the convex portions 55a and the concave portions 55b constituting the unevenness 55 are made large in size so as to have a gentle waveform. Thus, by making the shape of the buffer portion 32 into a waveform, a part of the game ball that bounces upward from the nail row and hits one convex portion 55a (recess portion 55b) is adjacent to the nail row without returning to the nail row. A phenomenon of rebounding toward the nail train after hitting the convex portion 55a occurs, and the momentum of the game ball can be rapidly reduced. For this reason, the lateral length of the buffer member 30 can be shortened to reduce the size and weight.
In addition, when the game ball that hits the convex portion 55a (the concave portion 55b) directly returns to the road nail row 21A and repeats bouncing, the momentum is sufficiently reduced as in the case of each of the above embodiments, and the start prize opening side Move to.

In addition, a fulcrum for rotating the buffer member 30 is provided at a position indicated by reference numeral 50 in the drawing so that the downstream portion (second buffer portion 32) of the buffer member 30 rotates in the vertical direction around the fulcrum 50. It may be configured. In this case, the lower surface of the buffer member is configured to rotate upward by a predetermined angle from the illustrated position. Thus, the buffering effect can be further enhanced by configuring the buffer member 30 so as to rotate in the vertical direction by the impact from the game ball.
Various sizes and pitches of the convex portions 55a and the concave portions 55b can be selected. For example, as shown in FIG. 15B, the individual convex portions 55a and the concave portions 55b constituting the arc-shaped irregularities 55 can be reduced in size. Good. Even when configured in this manner, the effect of rapidly reducing the momentum of the game ball can be exhibited as in FIG. Moreover, you may comprise so that the downstream part (2nd buffer part 32) of the buffer member 30 may rotate to an up-down direction centering | focusing on the fulcrum 50. FIG.
Further, the front shape of the second buffer portion 32 may be a zigzag uneven shape instead of the waveform.

In each of the above embodiments, it is assumed that the lower surface of the buffer member, in particular, the longitudinal sectional shape of the second buffer portion 32 is a horizontal flat surface as shown in FIGS. The shape of the buffer site can be selected variously.
That is, FIGS. 16A and 16B are cross-sectional views (cross-sectional views taken along line YY in FIG. 8) showing a configuration example in which the vertical cross-sectional shape of the second buffer portion is other than a horizontal flat surface. .
In the example of FIG. 16A, an example is shown in which the second buffer portion 32 of the buffer member is recessed upward. By selecting the shape of the second buffer portion 32 in this way, some of the game balls bounced upward on the nail train 21A bounce the route as shown in the figure and go downstream. Go and go. For this reason, the momentum of the game ball can be attenuated efficiently.
Next, in the example of FIG. 16B, the second buffer portion 32 of the buffer member is made flat and is inclined so that the back side of the flat surface faces upward. By selecting the shape of the second buffer portion 32 in this way, some of the game balls bounced upward on the nail train 21A bounce the route as shown in the figure and go downstream. Go and go. For this reason, the momentum of the game ball can be attenuated efficiently.

Next, FIGS. 17A and 17B are cross-sectional views showing a modification of the buffer member support structure of the present invention.
In this embodiment, the front end portion of the male screw portion 42a of the screw 42 inserted through the vertically long mounting hole 40 provided in the game board or the board surface component is screwed into the screw hole 34a in the boss portion 34 protruding from the back surface of the buffer member. 16 is the same as FIG. 16 except that the inner diameter of the mounting hole 40 is slightly larger than the male screw portion 42a of the screw so that the male screw portion moves within a range of 360 degrees within the mounting hole. ing. Further, rubber washers (for example, urethane rubber washers) 60 are interposed between the head of the screw 42 and the game board and between the boss portion 34 and the game board, respectively. The rubber washer 60 functions to return the buffer member 30 to the initial position after the buffer member is displaced by an impact from the game ball while holding the buffer member 30 in a predetermined initial position.
Since the buffer member 30 is configured in this way, the buffer member 30 receives the force from the game ball colliding with the bottom surface of the bottom plate and is displaced upward to rapidly reduce the momentum of the game ball. It can be removed (FIG. 17B). For this reason, the lateral length of the buffer member 30 can be further shortened to reduce the size and weight.

Next, FIGS. 18A and 18B are longitudinal sectional views showing the main configuration of another modified example of the present invention. In this embodiment, the bottom plate 30A of the buffer member is displaced (deformed) in the vertical direction. It is configured as possible. That is, for example, by providing the thin portion 30C between the lower portion of the front plate 30B of the buffer member and the bottom plate 30A, when the game ball collides with the lower surface, the bottom plate 30A is elastically bent upward and deformed, so that the game ball It may be configured to diminish momentum.
FIG. 18A is an example in which a recess is provided in a part of the bottom plate 30A to form a thin portion 30C, and FIG. 18B shows the front portion of the bottom plate as the thinnest portion 30C and heads backward. In this example, the thickness gradually increases.
With this configuration, the bottom plate 30A can be deformed upward by an impact (pressing force) when the game ball hits, and the momentum of the game ball can be reduced, and the bounce is suppressed and the ball speed is attenuated. It becomes possible.
The configuration of the present embodiment may be combined with the configuration of the movable buffer member shown in FIGS. 8 to 14 or may be combined with the embodiment shown in FIGS. 15 to 17.

In each of the above embodiments, in addition to the buffer portion 32 for buffering the ball that jumps up from the nail train, the buffer portion 31 for buffering the ball that jumps up from the windmill is provided, but only one of them may be configured. Good.
In each of the above embodiments, the nail that guides the game nail to the start winning opening is exemplified as the game nail that is disposed opposite to the buffer member, but the game nail row that generally guides the game ball to the winning opening other than the start winning opening A buffer member can be applied.
As described above, in the present invention, the game balls generated due to the high repulsive force of the game nails planted in the resin game board, and the game balls to the prize opening caused by other irregular behaviors. It is possible to effectively prevent variation in the entrance rate and entry into the inner part of the opening of the game board.
In addition, depending on the behavior of the windmill arranged upstream of the road nail row, variations in the way the game balls bounce occur, but a buffer member is arranged so that it overhangs directly above the road nail row and any bounce method Since the momentum of the game ball is suppressed by the buffer member, the behavior is sufficiently stable downstream and does not exhibit irregular behavior.
Further, by setting the height position of the bottom plate of the buffer member so high that it does not hit the normal height of the ball, it is possible to eliminate the concern that the game will be adversely affected.
