Description

  According to the present invention, a game board that has been conventionally constituted by a wooden plywood is constituted by a resin board such as acrylic, while a wooden plywood is used only for a portion where a game nail is to be planted. The present invention relates to a resin game board unit and a pachinko gaming machine that can solve the problem of fluctuations in the trajectory of a game ball.

Due to social demands such as environmental protection, resin game boards made of acrylic or the like are gradually being used instead of wooden plywood that has been conventionally used as game boards for pachinko machines.
Resin game boards are more durable than wooden plywood, have the advantage of being easy to mold into any shape, making it transparent, and being easy to color in any color, while planting game nails, There is a difficulty that it is difficult to screw the screw.
As a countermeasure, Patent Document 1 discloses a technique in which an interposition member made of a wood material is fitted into a through hole provided in a resin game board and a game nail is driven into the interposition member. According to this, since the game nail is driven into the wood portion provided at a position avoiding the resin material, it is possible to ensure the same workability as the conventional nailing operation on the wooden game board surface. However, since there are about 200 game nails planted on the game board surface, through holes for driving all game nails are formed in the game board surface, and interposition members are fitted into the through holes. In addition, it is clear that the operation of nailing the intervening member results in an increase in manufacturing man-hours, a decrease in productivity, and a cost increase associated therewith. In addition, there is a problem in the progress of the game that a step formed along the boundary line between the through hole and the interposition member adversely affects the flow trajectory of the game ball.

Next, in Patent Document 2, the number of game nails is reduced by fitting a resin member molded in a state where a plurality of game nails are previously planted into an attachment hole formed through a wooden game board. Techniques to do this are disclosed.
Further, Patent Document 3 discloses a technique that facilitates the flow adjustment operation of the game nail by fitting a planted board in which a game nail is planted in a mounting hole provided in the game board base.
However, when another member in which a game nail is implanted is placed in a hole formed in the game board surface as in Patent Documents 2 and 3, a step or groove is formed along the boundary between the game board surface and the game nail implantation member. The step and the like may be adversely affected on the flow path of the game ball flowing down in the vicinity of the game nail, making it difficult to adjust the flow path as calculated.
For example, as shown in FIG. 6, a game nail planting member 105 made of plywood is installed in a mounting hole 101 formed in the resin game board 100, and the game nail planted on each game nail planting member 105. When a game ball passage 115 is formed between nail rows consisting of 110, or when a game ball passage 115 is formed between a nail row and a board surface component, a mounting hole and a game nail are installed in each game ball passage 115. The boundary line A with the member will be located. Due to the accuracy error in manufacturing the resin game board and the game nail planting member, it is difficult to form the boundary line A without a step, and the boundary line A with respect to the game ball B passing through the game ball path 115 is difficult. The step along the line interferes and adversely affects the flow path of the game ball.

However, in the present invention, the position of the boundary line is set to a position that does not interfere with the game ball, so that such a problem can be solved.

Hereinafter, the present invention will be described in detail with reference to embodiments shown in the drawings.
FIG. 1A is a plan view showing a configuration of a main part of a resin game board unit according to an embodiment of the present invention, FIG. 1B is an XX sectional view, and FIG. 1C is a YY sectional view. is there.
The resin game board unit 1 includes a resin game board main body 2 provided with at least one mounting hole 3, a wooden plywood piece (game nail planting member) 10 installed in the mounting hole 3, and a plywood piece. And game nails 20 planted on the surface of 10. On the plywood piece surface and the resin game board main body surface, a game ball passage 30 along which the game balls B flow down is formed in a region along the game nail 20 and straddling the plywood piece surface and the resin game board main body surface. Yes.
As shown in FIGS. 1B and 1C, in this example, a support piece 4 that supports the back surface of the plywood piece 10 is disposed on the back side of the mounting hole 3, and the plywood piece is removed from the front side of the mounting hole 3. The plywood piece back surface is fixed to the support piece 4 by a fastener 5 such as a screw. In addition, the structure which fixes the plywood piece 10 in the mounting hole 3 is not limited to this.
The game nail 20 may be installed in advance on the surface of the plywood piece 10 and then the plywood piece may be mounted in the mounting hole 3, or the game nail may be mounted after the plywood piece 10 is mounted in the mounting hole 3. 20 may be planted.

The characteristic configuration of the present invention is that the boundary line S (contact line) between the inner peripheral edge 3 a of the mounting hole 3 and the outer peripheral edge 10 a of the plywood piece 10 is located in the game ball passage 30. , So that the boundary line S (stepped portion or gap) between the inner periphery of the mounting hole and the outer periphery of the plywood piece does not interfere with the game ball B passing through the game ball passage 30. It is in the point set to.
In the example of FIG. 1A, a plywood piece 10 is fitted in two mounting holes 3A and 3B formed in parallel at a predetermined interval, and the surface of each plywood piece 10 has its The game nails 20 are planted in a line along the longitudinal direction. A game ball passage 30 is formed between the game nail rows on each plywood piece 10. When the diameter of the game ball B is D (about 1.1 cm), the distance L between the outer peripheral edge 10a of the plywood piece 10 and the game nail (row) 20 is less than D / 2 (about 5.5 mm). Is set to
Here, the game nail 20 in the case of the interval L between the game nail 20 and the boundary line S is the outer peripheral surface of the rod-shaped main body 20a excluding the large-diameter head of the game nail as shown in FIG. And the boundary line S.
Therefore, the distance L is the distance between the boundary line S and the contact position C where the rod-shaped main body 20a of the game nail and the game ball B contact. Thus, by setting the distance L between the contact position C and the boundary line S to be ½ or less of the diameter of the game ball B, the contact portion between the game ball and the game ball passage 30 is always outside the boundary line S. , And no interference with the steps and grooves formed along the boundary line S.

Further, when the game nail is not erected perpendicularly to the surface of the plywood piece, that is, when it is inclined to the game ball passage 30 side (FIG. 1 (d)), it is inclined to the opposite side to the game ball passage. In the case ((e)), the distance from the contact position C between the rod-shaped main body of the game nail and the game ball to the boundary line S located in the game ball passage is the interval L, and the interval L is Since the diameter of the ball B is ½ or less of the diameter of the ball B, the contact portion between the game ball and the game ball passage 30 is always outside the boundary line S and interferes with a step or a groove formed along the boundary line S. Nothing will happen. In other words, the game nail is assumed not only when the game nail is vertically erected, but also when the game nail is inclined to the opposite side of the game ball passage as shown in FIG. It is effective that the planting position of the nail 20 is close to the boundary line S (the interval L is made narrower than when the game nail is vertical).
In this way, a plurality of game nails 20 are formed in the plywood piece 10 in a row, and a game nail row 20L planted at such a narrow interval that the game nails cannot pass therethrough. When the area between S forms part of the game ball passage 30, the distance L between the individual game nails (contact position C) constituting the game nail row and the boundary line S is determined as the game ball. The contact point between the game ball B and the game ball passage 30 passing through the game ball passage 30 is always at a position that avoids the boundary line S, and the step formed on the boundary line S, The groove no longer interferes with the game ball.

Next, FIGS. 2A and 2B are a plan view and a YY cross-sectional view showing a main part configuration of a resin game board unit according to another embodiment of the present invention, and a plurality of game nails 20. The plywood pieces 10 arranged in a row so as not to pass through the game balls are fitted into the mounting holes 3, and the game nail row 20 </ b> L and the board parts spaced apart on both sides of the game nail row A game ball passage 30 is formed between the player and the player.
In this way, even when the game ball passage 30 is formed between the game nail row 20L and the board part 35, the boundary located on the game nail 20 and the board part 35 side is the same as in the case of the above embodiment. The distance L from the line S is set to be less than D (diameter of the game ball) / 2 (about 5.5 mm). With this configuration, even if the game ball B passing through the game ball passage 30 moves while contacting the game nail 20, the boundary line S does not interfere with the game ball, and the movement trajectory of the game ball is adversely affected. Will not be affected.
In each of the above embodiments, the case where a plurality of game nails 20 are linearly arranged on the plywood piece 10 has been described, but when the game nails 20 are arranged so as to draw a curve as shown in FIG. In addition, when arranged so as to draw a bent line as shown in (b), even when the game ball passage 30 exists in an area adjacent to the game nail row 20L, interference between the boundary line S and the game ball is prevented. The above-described configuration can be applied.
When the game ball passages 30 are formed by the game nails 20 planted along the outer peripheral edges 10 a of the two plywood pieces 10 arranged close to each other in this manner, the game ball passages 30 are located on both sides of the game ball passage 30. The position of the boundary line S is appropriately set so that each boundary line S and the game ball do not interfere with each other.

Next, FIG. 4 is a plan view showing an example in which a plurality of plywood pieces having different shapes and arrangements of game nails are arranged adjacent to each other. In this arrangement example, when the area between the game nail row arranged along the outer peripheral edge of each plywood piece and the boundary line S is included in the game ball passage 30, the game ball and the boundary line S Since there is room for the problem of interference, the distance L between the above regions (the distance between the contact position between the game nail and the game ball and the boundary line S) is less than half the diameter of the game ball B. To do.
Also, when two plywood pieces 10 are in direct contact with their outer peripheral edges 10a, as in the game ball path indicated by reference sign D in FIG. 4, a step or groove is formed on the boundary line S. The present invention is applicable. That is, for example, even when the game ball passage 30 is formed by the game nail rows 20L erected along the outer peripheral edges of two plywood pieces arranged adjacently in contact with the outer peripheral edges, the boundary line is also formed. Since it is necessary to interfere with the game ball, interference with the game ball can be avoided according to the present invention. In this case, it is sufficient to place the boundary line S close to one game nail row (left side) so that L <B / 2. The other game nail row may be sufficiently separated from the common boundary line S.

In each of the above embodiments, only the case where the game nail is planted on the surface of the plywood piece 10 has been described. However, as shown in FIG. 5, the board part 35 is mounted on the surface of the plywood piece 10. In addition, the present invention can be applied to the case where the game ball passage 30 is formed on the side surface side of the board surface component.
That is, in this example, the board surface component 35 is disposed along the outer peripheral edge 10a of the plywood piece 10, and the distance L between the side surface (contact position with the game ball) 35a of the board surface part 35 and the outer peripheral edge 10a is set as the game ball B. By making the diameter less than ½ of the diameter D, it is possible to prevent the game ball B passing while contacting the side surface 35a of the board surface component from being affected by the boundary line S and causing fluctuations in the movement trajectory.
For a region where the game ball passage 30 is not formed, there is no need to regulate the positional relationship between the boundary line S and the game nail.
It should be noted that the structure for preventing interference with the game ball according to the present invention is not limited to the configuration example shown in each figure, but generally when a game ball passage is formed along a game nail or a board component mounted on a plywood piece. Can be applied.

As described above, according to the present invention, when a game nail planted along the outer peripheral edge of the plywood piece or a game ball passage is formed outside the board surface component, the plywood piece and the mounting hole The boundary line is located in the game ball passage, which may cause unnecessary fluctuations in the flow path of the game ball. However, in the present invention, the boundary line position is set to a position that does not interfere with the game ball. Such problems can be solved.
In addition, when at least two plywood pieces are arranged in contact with the outer peripheral edge and the boundary line between both plywood pieces is located in the game ball passage, the game ball and the boundary line passing through the game ball passage Cause interference problems. In this case as well, it is effective to set the distance between the boundary line and the game nail or the board component so that the boundary line does not interfere with the game ball passing through the game ball passage.
In particular, in order to prevent interference between the game ball passing through the game ball passage and the boundary line, the position of the boundary line should be set to the distance between the game nail or the side surface of the board component (contact position with the game ball) and the boundary line. It is effective to make it less than 1/2 of the diameter of the game ball.
Further, when the game nails are implanted in a row, it is effective to configure so that the distance between each game nail and the boundary line is less than ½ of the diameter of the game ball.
Further, when a plywood piece is mounted in the mounting hole from the front side, it is effective to support it with a support piece provided on the back side of the mounting hole.
Further, the resin game board unit of the present invention can be applied to a game board surface of a pachinko game machine or other game machines using game balls.
