Description

  The present invention relates to a ball set member for billiards. More specifically, the present invention relates to a pocket billiard nine ball game, bowler game, eight ball game, and rotation game (hereinafter also simply referred to as nine ball, bowlard, eight ball, and rotation). At the start of each game, the required nine, ten, and fifteen balls (target balls) belong to the technical field of ball set members that properly arrange the balls.

  When a pocket billiard game is started, it is necessary to set a predetermined number of balls according to the game in close contact with each other on the billiard table. As the setting procedure, a diamond-shaped wooden rack 70 shown in FIG. 17 or a wooden frame called a triangular wooden rack 80 as shown in FIG. 18 has been used.

  That is, in the nine balls, the nine balls 1... Are arranged in close contact with each other in the order of 1−2−3−2−1−1 from above in FIG. Therefore, a diamond-shaped rack 70 manufactured to have a size surrounding the outer periphery of the balls 1.

  In the eight ball game or the rotation game, 15 balls 1..., As shown in FIG. In order to arrange them in a triangular shape arranged in close contact with each other in this order, a rack 80 manufactured in a triangular shape having a size surrounding the outer periphery of the balls 1.

  However, since the racks 70 and 80 which are generally used are lacking in accuracy in size and detail shape, it is difficult to set the balls 1. It is. Alternatively, there is a case where the ball 1 is intentionally set without being in close contact, or the ball 1. It takes.

  In the end, it is unavoidable that a ball 1 that is not in close contact with each other is unavoidable. When a break occurs, the force transmitted from the target ball (ball) 1 hit by the hand ball is interrupted at the position of the ball 1 that is not in close contact with the ball 1. ... is not neatly scattered. Therefore, unfairness arises and is a problem. In the first place, if the balls 1... Are in close contact with each other, the central ball 9 is left, and the other balls 1.

In this regard, according to Patent Document 1, it is possible to set the ball more appropriately than using the conventional wooden frames 70 and 80. That is, in the same document 1, nine annular pressure-sensitive adhesive sheets 92 matched with the nine ball arrangement positions were pasted between the rectangular transparent vinyl sheet 91 and the release sheet as shown in FIG. A nine-ball positioning sheet 90 having a structure is used, and an annular pressure-sensitive adhesive sheet 92 having a size and thickness that is affixed to a billiard cloth on the surface of the billiard table and does not interfere with the rolling of the ball is used. A method of placing a ball in the small-diameter round hole 93 provided is disclosed.
Japanese Patent Laying-Open No. 2005-270252 (FIGS. 1 and 2)

  However, according to the sheet 90 of the above-mentioned Patent Document 1, nine annular pressure-sensitive adhesive sheets 92... Previously matched with nine ball arrangement positions must be pasted on the rectangular transparent vinyl sheet 91. Its manufacture requires accuracy and is troublesome.

  Moreover, in use, the peeling sheet is peeled off, and the nine annular adhesive sheets 92... Are stuck on the billiard cloth on the billiard table surface. In addition, if the ball goes back and forth on the transparent vinyl sheet 91 and warps or peels off from the edge of the sheet 91, the game may not be established.

  Moreover, it must be said that the transparent vinyl sheet 91 and the adhesive sheet 92 are thick and the resistance of the ball passing thereover is large. Further, as described above, the manufacturing cost of the transparent vinyl sheet 91 and the adhesive sheet 92 and the nine annular adhesive sheets 92 attached between them is high.

  Therefore, the object of the present invention is to easily and reliably arrange a proper arrangement in which each ball is in contact with each other when setting the ball at the start of a game such as a pocket billiard nine ball or an eight ball, although it is a compact design. An object of the present invention is to provide a billiard ball set member which can be carried out and can be easily removed when not needed, and which can reduce the production cost.

  In the first aspect of the present invention, the restraint frame assembly forming the ball set member for nine balls is formed thin with a frame having a hollow portion in which the overall shape is hollowed out, and adjacent to the nine balls. The balls are formed in the minimum size necessary to keep the balls in contact with each other and maintain a proper arrangement without gaps, so that the ball can be easily and reliably placed in the proper position at the start of the game while having a compact design. It is convenient to set and allows smooth game progression. Moreover, since the minimum necessary size of the hollow is sufficient, it contributes to a reduction in the manufacturing cost of the ball set member.

In addition, the present invention is configured so that the force in the 9th ball direction acts on each of the 8 balls on the outer periphery excluding the 9th ball located in the center among the 9 balls set with nine balls. Each ball excluding the 9th ball has a force acting in the direction of the 9th ball in the center because it is formed in a roughly rhombus shape that is such that the restraint frame assembly is located slightly outside the lower surface of each outer ball. They are constrained in an appropriate arrangement while being in contact with each other, and each ball can be neatly scattered symmetrically, leaving the 9th ball at the time of the break, contributing to the fairness of the game.

In the invention of claim 2 , the inner shape of the restraint frame assembly that contacts the lower surface of each of the eight outer balls excluding the ninth ball located in the center among the nine balls set with nine balls, Since it is formed in a square shape, an arc shape, or a straight line shape, the certainty that each ball except the 9th ball is moved toward the 9th ball is further increased.

The invention described in claim 3 relates to a restraint frame assembly that constitutes a ball set member for bowlards, and is thinly formed with a substantially triangular frame having a hollow portion with an overall hollow shape, and the ten balls. In the bowlerd, as in the nine balls of the invention of claim 1, Although it has a compact design, it is convenient to set the ball easily and surely in the proper position, and the game progresses smoothly and the minimum required size of the hollow is sufficient. It also contributes to lower costs.

The present invention also provides a lower surface of each of the outer peripheral balls so that a force in the central ball direction acts on each of the outer peripheral balls excluding the centrally located ball among the ten balls set by the bowlard. Since the constraining frame assembly is formed in a substantially triangular shape slightly outside, the balls other than the central ball are similar to the nine balls according to the first aspect of the present invention. The force works in the direction of the ball and abuts each other, and at the time of the break, each ball can be scattered symmetrically while leaving the center ball, contributing to the fairness of the game.

In the invention according to claim 4 , the inner shape of the restraint frame assembly that contacts the lower surface of the outer peripheral balls excluding the ball located at the center among the ten balls set by the bowlard is a square shape, an arc shape, or a straight line. since Jo to being formed, even in Bourado, like the Nine ball of the invention of claim 2, the balls except the center of the ball is attracted reliably in the direction of the center of the ball.

According to the fifth aspect of the present invention, the restraint frame assembly forming the ball set member for the eight ball or the rotation is formed thin with a substantially triangular frame having a hollow portion with a hollowed out overall shape. Since the adjacent balls of the individual balls come into contact with each other and are formed in a minimum size necessary to maintain a proper arrangement without a gap, the same excellent effects as those of the invention of claim 3 can be obtained. .

In addition, the present invention is such that the force in the three ball directions in the center acts on each of the outer peripheral balls excluding the three balls located in the center among the 15 balls set in the eight balls or the rotation. Since the constraining frame assembly is formed in a substantially triangular shape that is positioned slightly outside the lower surface of each ball on the outer periphery, the same effect as that of the invention of claim 3 is obtained.

In the invention described in claim 6 , the inner shape of the restraint frame assembly that abuts the lower surface of the outer peripheral balls excluding three balls located at the center among the 15 balls set by the eight balls or the rotation is a square shape. Since it is formed in a circular arc shape or a straight line shape, the same effect as that of the invention of claim 4 is obtained.

In the seventh aspect of the invention, since the angle inside the rectangular shape of the restraint frame assembly is 120 °, the ball partially placed on the inside of the square shape of the restraint frame assembly is in the direction of the center ball. It is excellent in accuracy.

In the invention according to claim 8, since the thickness of the restraint frame assembly is 10 μm to 200 μm so that the ball passing through the upper surface of the restraint frame assembly is hardly caused, Even if the restraint frame assembly is left on the upper surface of the billiard table during the game, there is no problem in the game.

Incidentally, the Rukoto provided grippable protrusion on the outer periphery of the restraining framework body, when using the constraint framework body when the game starts, can be set to comfortably billiards table top pinching the projecting piece. After the break, it is convenient that the restraint frame assembly that is no longer needed can be easily removed by pinching the projecting piece.

A preferred embodiment of the ball set member for billiards of the present invention will be described below with reference to the drawings. In addition, since the embodiment regarding the invention of Claims 1-8 is common, it demonstrates collectively as follows.

1 to 12 show the configuration of a ball set member suitable for a nine ball game (see claims 1 and 2 ), and FIGS. 13 to 16 show the configuration of a ball set member suitable for a bowler game (see claims 3 and 4 ). Show. Since a ball set member suitable for an eight ball game or a rotation game using 15 balls (see claims 5 and 6 ) can be applied in the same manner as the ball set member for bowlers, the description thereof is omitted.

  First, the structure of the ball set member for nine balls shown in FIGS. 1 to 12 will be described. The billiard ball set member is as shown in FIG. 2 among the nine balls S-1 set at the start of the game of the pocket billiard nine ball game (before the break) as shown in FIG. It is preliminarily placed outside the position u immediately below each of the eight balls 1 on the outer periphery excluding the ninth ball p located at the center. Then, by simply laying in such a manner, the arrangement state in which the nine balls 1, 1 are in close contact with each other can be constrained, and can be easily removed when not needed.

  The ball set member of FIG. 1 can be said to be a “corner type” ball set member by paying attention to an important inner shape.

  The constraining frame assembly A constituting the ball set member has a hollow portion 7 in which the overall shape is hollow, and is formed to be extremely thin by a laminate 2 or a synthetic resin frame 2 having a certain degree of hardness. ing. As the synthetic resin, polyethylene terephthalate (PET) is suitable. In addition, it can be formed of a cell film such as acetate, paper, metal, wood or the like. The thickness t (see FIG. 5) of the restraint frame assembly A is preferably 100 μm, assuming that little resistance is generated on the ball 1 passing through the upper surface 11 of the restraint framework assembly A. It is implemented in the form between 10 μm and 200 μm.

  The frame 2 is preferably transparent, but may be implemented with colors and patterns (see FIG. 8). In addition, the frame 2 is formed on an extremely thin flat surface as described above, but can be implemented in a form in which the frame 2 is gradually inclined inward (not shown).

  Further, the restraint frame assembly A has the minimum size necessary for maintaining an appropriate arrangement state in which the adjacent balls 1 in the nine balls 1. Among the nine balls S-1, the center of gravity x of each of the eight balls 1 on the outer periphery excluding the ninth ball p located at the center is inclined in the direction of the ninth ball p. Each of the balls 1 is formed in a substantially rhombus shape having a size such that the restraint frame assembly A is located slightly outside the lower surface 10.

  And among the nine balls S-1 to be set, the inner shape of the restraint frame assembly A (frame assembly 2) that comes into contact with the lower surface 10 of each of the eight outer balls 1 excluding the ninth ball p located at the center. k is formed on the inner side 3 of the square shape.

  Specifically, as shown in FIG. 4A, the nine balls S-1 to be set have six balls 1... Adjacent to the ninth ball p, which is the ball m located at the center, as hexagons. Arranged in shape. That is, when the centroids x of the six balls 1 adjacent to the ninth ball p are connected, the inner angles become 120 °. Therefore, the inner shape k of the frame 2 has an angle θ such that the forces (detailed below) acting on the six balls 1... Are directed to the center (x) of the ninth ball p. It is formed on a 120 ° square inner side 3. The angle θ of the inner shape k of the frame 2 on which the two balls 1 and 1 positioned at the remaining top are placed is also formed at the same 120 °. Therefore, the inner shape k of the frame 2 with which the lower surface 10 of the eight balls 1 excluding the 9th ball p (see the range of the symbol w in FIG. 6 described later) abuts is the inner side of the square shape with an angle θ = 120 °. 3 is formed.

  The width of the frame 2 forming the restraint frame A is preferably about 3 mm to 30 mm. The width dimension of the frame 2 shown in FIG. 2 is formed such that, for example, the length between the reference numerals 30 and 36 is 5 mm, and the distance between the reference numerals 34 and 35 is 5 mm. This is because the upper surface 8a of the billiard table 8 is made of rusha, but when the ball 1 is placed on the upper surface 8a of the rusher, the lasher is dented by its own weight. The depression range (a range of about φ = 4 mm) is indicated by a symbol w in FIG. 6, and the width dimension of the frame 2 is set so that the depression range w reaches the frame 2 and is positioned inside the frame 2. (Size) is set (the same applies to each of the following constraint frame assemblies). However, the shape of the outer edge of the frame 2 is not particularly limited, and may be a straight line, a curved line, or an angular shape.

  In other words, the frame 2 is shaped as follows so that the center of gravity x of the ball 1 is located slightly inside the inner edge 31 of the frame 2 (FIGS. 2 and 6). Note that the diameter of the ball 1 is 57 mm and is designed in consideration of this.

  In the frame 2 of the constraining frame A shown in FIG. 2, the length from the center x of the center No. 9 ball p to the inner edge 30 of the left and right frame 2 positioned on the horizontal line is 60 mm each. The length (inner dimension) between the inner edges 30 and 30 is 120 mm. Therefore, the center of gravity x of the left and right balls 1 is located 3 mm inside the inner edge 30.

  Next, at the position of the one inner edge 30, an inner edge 31 is located at a position extending 60 mm inward at an angle of 60 ° from the horizontal line connecting the left and right inner edges 30, 30, and further from the inner edge 31 in the horizontal direction. The inner edge 32 is located at a location extending 5 mm inward. Therefore, at the position of the inner edge 31, an inner side 3 having an angle θ of 120 ° is formed.

  Subsequently, a top inner edge 34 is located at a position extending 60 mm inward at an angle of 60 ° from the position of the inner edge 31, and the inner angle θ of the top inner edge 34 is 120 ° so that the inner angle θ is 5 mm inward from side to side. The inner edges 33 and 33 are located in the returned part. One inner edge 33 and the inner edge 32 are connected. Thus, at the position of the top inner edge 34, the angle-shaped inner side 3 having an angle θ of 120 ° of the inner shape k is formed.

Therefore, among the nine balls S-1 to be set, each of the eight balls 1 (the lower surface 10) on the outer periphery excluding the ninth ball p located at the center is enlarged as shown in FIG. The frame 2 is positioned outside the point u that hangs down from the center of gravity x (directly below the center point of the ball 1), and a part of the frame is placed on the upper surface 11 of the frame. An inward force 9 approaching the p direction works slightly, and inclines in the direction of the ninth ball p and comes into contact with the adjacent ball 1. The 9th ball p is placed directly on the upper surface 8a of the billiard table 8 in the hollowed portion (hollow portion 7) of the frame 2, and there is no resistance to the frame 2.

  Here, FIG. 6, which is a partially enlarged view of the ball 1 indicated by reference numeral 100 in FIG. 2, shows details of the eight balls 1 on the outer periphery excluding the ninth ball p in the direction of the ninth ball p. It explains using.

  In the frame 2, one base (the frame portion below the reference numeral 31 in FIG. 6) of the rectangular inner side 3 that forms the internal angle θ = 120 ° is connected to 2 a and the other base (reference numeral 31 and reference numeral 32 in FIG. 6 is connected). The frame portion above the line is 2b. The base portion 2 a and the base portion 2 b forming the frame 2 serve as step members for the ball 1. Accordingly, the center of gravity x of the ball 1 is inward of the bases 2a and 2b, and a part of the outer surface of the ball lower surface 10 is placed on the base 2a. . Similarly, when a part of the outer surface of the ball lower surface 10 is placed on the base 2 b, a force that tries to roll in the direction of the symbol q acts on the ball 1. Thus, the force in the sign j direction of the resultant force of the signs n and q works. This force in the j direction acts on the center 9th ball p.

  Thus, a force 9 in the direction of the ninth ball p acts on each ball 1 except the ninth ball p in FIG. At this time, in the 9th ball p, the force 9 in the 9th ball p direction works from the opposite direction, but it works by canceling out the 9th ball p, and the force in the 9th ball p is Because it becomes zero, the 9th ball p does not move. In this state, all the balls 1... Are suspended in force relation and do not move in contact with each other, and an appropriate position is realized while closely contacting each other.

  Therefore, the restraint frame assembly A (frame assembly 2), which is the ball set member, is laid in advance under the nine balls S-1 set on the upper surface 8a of the billiard table 8 as shown in FIG. After that, by simply arranging the nine balls 1... In the restraint frame assembly A in the order of 1-2-3-2-1, the balls 1 and 1 are easily brought into contact with each other (in close contact). ) And can be arranged constrained to an appropriate position. If the balls are properly arranged in this way, the game starts immediately. Then, the force acting on the target ball (ball) 1 hit first by the front ball (ball) 1 hit by the cue y at the break is reliably transmitted to each ball 1... The balls 1 are scattered cleanly, leaving the ball p, and the game progresses fairly for the game players.

  Since the basic structure of the restraint frame assemblies B, C, D, E, and F (FIGS. 7 to 12) of the ball set member described below is the same as that of the corner type restraint framework A described above, the overlapping portions are omitted. The description will focus on the different parts.

  In the restraint frame assembly B of the ball set member shown in FIG. 7, the inner shape k of the square shape 3 of the restraint frame assembly A is formed in an arc shape (4). In the vicinity of the inner edge 31 of the rectangular inner side 3 (k) (see FIG. 2), the lower surface 10 of the spherical ball 1 contacts only at two points. The ball set member B having the arcuate inner side 4 has an infinite number of the two contact points. In FIG. 7, the length between the left and right inner edges 40 is 40 mm. Therefore, similarly to the restraint frame assembly A, a force 9 in the direction of the 9th ball p acts on each of the eight balls 1 except the 9th ball p, and the balls 1 and 1 are securely connected to each other. Abut.

  The constraining frame assembly C in FIG. 8 employs many arcuate curves larger than the curvature of the inner shape k of the arcuate inner side 4 in the constraining frame assembly B. It can be said to be a “circle type” ball set member. As a whole shape, it is formed in the frame 2 having a circular shape at the center portion, and a shape in which the front and back thereof protrude in a mountain shape.

  In addition, the part shown with the code | symbol 6 in the same figure is the protrusion which can be picked and grasped with a finger when it is unnecessary after a break. The same material and thinness as the frame 2 are preferable. It is separately provided at the outer peripheral end of the frame 2 or is integrally formed with the frame 2 (see FIG. 12). This protruding piece 6 may be provided not only for the restraint frame assembly C of the present embodiment but also for other restraint frame assemblies A, B, D, E, F, G, H, and I. Is possible.

  The relationship among the nine balls S-1 set in the restraint frame assembly C is shown in FIG. The centroids x of the eight balls excluding the center ninth ball p are located slightly inward from the arcuate inner side 4 (k). Therefore, as in the case of the restraint frame assemblies A and B, an inward force 9 approaching the 9th ball p direction acts on each ball 1 due to the presence of the frame 2 such as a step member, and the adjacent balls 1 and 1 are Abutted.

  In the restraint frame assembly D of the ball set member in FIG. 10, the inner shape k of the square shape 3 of the restraint frame assembly A is formed in a straight line 5. In other words, it is a “straight type” ball set member. Each straight inner 5 (k) is formed in a direction perpendicular to the center of gravity x of the center 9th ball p (not shown), and the length of the straight portion arranged at right angles is 10 mm. The length between the left and right inner edges 50 is 50 mm. Even with this “straight type” restraint frame assembly D, each of the eight balls 1 (lower surface 10) except for the ninth ball p is subjected to a step on the linear inner side 5 (k), as described above. The force 9 approaching in the direction of the count ball p works reliably.

  The constraint frame assembly E shown in FIG. 11 is a so-called “fusion type”. The rectangular inner side 3 in the restraint frame assembly A, the arcuate inner side 4 in the restraint frame assembly B, and the linear inner side 5 in the restraint frame assembly D are combined. In the figure, the upper inner edge is formed on the square inner side 3, the lower inner edge is formed on the linear inner side 5, and the left and right inner edges are formed on the arcuate inner side 4, respectively. As described above, the inner shape k of the frame 2 of the ball set member can be implemented in a form in which three types of the rectangular inner side 3, the arcuate inner side 4, and the linear inner side 5 are appropriately combined.

  In the present embodiment, among the nine balls S-1 to be set, the balls 1 placed in the second row and the second row 2 each have a place placed on the lower surface 10 of the ball 1. Although the portion corresponding to the above-mentioned square inner side 3, arcuate inner side 4, and linear inner side 5 is not formed, the force 9 in the center 9th ball p direction acts on each set ball 1. , There is no change in abutting each other.

  The constraining frame assembly F shown in FIG. 12 is configured as a simple type in which the inner shapes k of the inner edges of the upper, lower, left and right sides of the constraining frame assembly E in FIG. The angle θ of the left and right rectangular inner side 3 is 120 °, and the angle θ of the upper and lower rectangular inner side 3 is 60 °.

  Next, the structure of the ball set member for the bowler game shown in FIGS. 13 to 16 will be described. The billiard ball setting member includes 10 balls S-2 set in the order of 1 to 2 to 3 to 4 as viewed from the front (upper side of the drawing) as shown in FIG. 4B. It is suitable for arranging closely. Each of the constraining frame assemblies G, H, and I is thinly formed with an equilateral triangular frame 2 having a hollow portion 7 with an overall shape hollowed out, and adjacent balls in the ten balls 1. 1 and 1 are in contact with each other and are formed in a minimum size necessary for maintaining an appropriate arrangement without gaps.

  The restraint frame assembly G of the ball set member shown in FIG. 13 will be described. The basic structure of the constraint frame assembly G is similar to the constraint frame assembly A. The overall shape is an equilateral triangular shape that is half of the rhomboid restraint frame assembly A. In FIG. 14, when each ball 1... Of the ten balls S-2 to be set is indicated by an imaginary line, the first row, the second row, the third row, and the fourth row from the top. The length between the inner edges 60 and 60 (inner dimensions) of the frame 2 corresponding to the fourth row in which the four balls 1 are arranged is 177 mm. At each inner edge 60, a triangular inner side 3 (k) having an inner angle θ = 120 ° is formed.

  Further, in the fourth row, the inner edge 64 is positioned in the frame 2 positioned in the horizontal direction 60 mm inward from the left and right inner edges 60, and the inner shape k of the inner edge 64 is also formed on the inner side 3 of the 120 ° square shape. Has been. The distance between the left and right inner edges 64 is 64 mm. The length from the central position 65 between the inner edges 64, 64 to the following inner top edge 63 is about 154 mm.

  In the third row in which three balls 1 are arranged, the inner edge 61 is located at a position extending 60 mm inward at an angle of 60 ° from the position of the inner edge 60 in the fourth row, and the inner angle θ of the inner edge 61 is 120. A portion formed by securing 5 ° inward and returning 5 mm inward is connected to a nearby portion among the portions secured by 120 ° at the inner edge 60 and returning inward by 5 mm to the left and right. Therefore, at the position of the inner edge 61, a rectangular inner side 3 having an inner shape k of θ = 120 ° is formed. The length between the left and right inner edges 61, 61 is 120 mm.

  In the second row in which two balls 1 are arranged, an inner edge 62 is located at a position extending 60 mm inward at an angle of 60 ° from the position of the inner edge 61 in the third row. A rectangular inner side 3 is formed extending inwardly by 5 mm and having an inner shape k of θ = 120 ° at the position of the inner edge 62. The length between the left and right inner edges 62, 62 is 63 mm.

  In the first row in which one ball 1 is arranged, a top inner edge 63 is located at a position extending 60 mm inward from the position of the inner edge 62 at an angle of 60 °, and the inner angle θ of the top inner edge 63 is 120 °. A portion that has been secured and returned 5 mm inward to the left and right is connected to a portion that extends 5 mm in the horizontal direction from the inner edge 62. Thus, at the position of the top inner edge 63, a rectangular inner side 3 having an inner shape k of θ = 120 ° is formed.

  Therefore, in the frame 2 of the restraint frame G shown in FIG. 14, the center of gravity x of each ball 1 excluding the central ball m (1) has the inner edges 60, 61, 62, 63, Therefore, the force 9 is applied to each ball 1 in the direction of the center ball m. Between adjacent balls 1, 1 abuts and no gap occurs.

  Next, the constraining frame assembly H shown in FIG. 15 is one in which the rectangular inner side 3 (k) of the constraining frame assembly G is formed in a straight line (5). Each straight inner 5 (k) is formed in a direction perpendicular to the center of gravity x of the central ball m (1) (not shown), and the length of the straight line portion arranged at right angles is 10 mm. Therefore, also with this “straight type” restraint frame assembly H, each of the nine balls 1 excluding the central ball m is affected by the step on the linear inner side 5 (k), as described above. The force 9 approaching the ball m direction works reliably.

  16 is configured as a simple type in which only the inner shape k of the inner edges of the first and fourth rows is formed on the arcuate inner side 4. Although it is a simple structure like the restraint frame assembly F of FIG. 12, each ball 1... Is brought close to the center ball m and the intended effect of contacting each other can be exhibited.

  Finally, although not shown in the drawings, a preferred restraint framework for the 15 balls S-3 (see FIG. 4C) set at the start of the game of the eight ball game or the rotation game is the above-described restraint framework for bowlard. This can be dealt with by increasing the size of the bodies G, H, and I, or increasing the number of inside 3 (4, 5) such as a square shape.

  For example, in the frame 2 having an equilateral triangle shape as in the constraining frame assembly I shown in FIG. 16, the side (inner dimension) is about 228 mm and the height (inner dimension) is about 197.5 mm. Embodiments are preferred. Therefore, among the 15 balls S-3 set as shown in FIG. 4C, each of the balls 1. Since the force 9 in the m, m, and m directions acts and the adjacent balls 1 and 1 come into contact with no gap (see FIG. 14), the game can be started fairly.
