Description

The present invention relates to a non-electric winning device.

Conventionally, as a prize-winning device of this type, a second-class non-motor is arranged on a game board, and the stage portion rotates about a rotation axis and falls forward to open a game ball into which a game ball can flow in. Those provided with an accessory have been proposed (see, for example, Patent Document 1). This type 2 non-electric accessory is provided with a lock arm that displaces the stage portion to an open state by transmitting a force to the stage portion. The lock arm has a first claw portion, a second claw portion, a rotation shaft, and an operating convex portion protruding from the main body portion, and when the stage portion is in the upright state (closed state), the first claw portion is the stage. The stage portion is locked in an upright state by engaging with the restrained shaft of the portion. Then, the lock arm has a rotating shaft so that when the game ball flowing down in the operating flow path for operating the second type non-electric accessory comes into contact with the operating convex portion, the operating convex portion is pushed by the weight of the gaming machine. The first claw portion is separated from the stage portion, and the second claw portion comes into contact with the lower surface located behind the rotation axis of the stage portion to push up the lower surface. As a result, the stage portion falls forward and is in an open state in which the winning opening is opened. When the game ball flowing down in the operating flow path separates from the lock arm, the lock arm is released from being pressed by the game ball and is displaced so as to return to the original position. When the lock arm is displaced to the original position and the first claw portion reaches the stage portion in the inverted state, the stage portion is restrained by being caught by the rear end portion of the stage portion, and the stage portion is held in the open state. When the game ball enters the open stage part, the gravitational moment given to the rotation axis of the stage part becomes large, so that the first claw part of the lock arm separates from the stage part, and the lock arm and the stage part become The engagement is disengaged and the stage is released from the lock arm. Then, the stage portion rotates backward while receiving the weight and momentum of the game ball, and returns to the standing state (closed state).

It has become. Further, on the downstream side of the ball entry port 41 in the front side ball passage unit 40, a plurality of front side ball passages 42 to 44 through which the game balls that did not enter the ball entry port 41 flow down are formed. .. The plurality of front side ball passages 42 to 44 are connected via branch portions and confluence portions so that the game balls flow down from the upstream to the downstream. A winning opening 61 and an opening / closing unit 70 for opening and closing the winning opening 61 are arranged in some of the front side ball passages 43 and 44 (straight ball passages extending vertically).

As shown in FIG. 4, the back side ball passage unit 50 is fixed to the back side of the game board 3 with respect to the base 30. The back side ball passage unit 50 is formed with two back side ball passages 51 and 52 through which the game ball that has entered the ball entry port 41 flows down. The two back side ball passages 51 and 52 are linear passages arranged in parallel with each other in the vertical direction, and upstream of the two back side ball passages 51 and 52, the game balls that have entered the ball entry port 41 are placed on the two back side balls. A distribution device (not shown) for distribution to any of the passages 51 and 52 is arranged. As shown in FIG. 3, one of the two rear side ball passages 51 and 52 communicates with one of the elongated holes 32 of the base 30. Similarly, of the two back side ball passages 51 and 52, the other back side ball passage 52 communicates with the other elongated hole 33 of the base 30.

As shown in FIG. 4, the winning opening unit 60 is fixed to the front surface of the base 30 so as to be arranged on the back surface of the front side ball passage unit 40. The winning opening unit 60 has a winning opening 61 opened and closed by one opening / closing unit 70 arranged in the front side ball passage 42 of the front side ball passage unit 40, and the other opening / closing unit 70 arranged in the front side ball passage 43. It has a winning opening 62 which is opened and closed by. A ball entry detection switch for detecting the entry of a game ball is arranged in each winning opening 61, 62, and when the entry of a game ball is detected by the entry detection switch, a specified number of prize balls are paid out. It is designed to be used.

The two opening / closing units 70 are displaced into an open state (a winning state) that allows a game ball to win a prize in the corresponding winning openings 61 and 62 and a closed state (a winning state) that makes it impossible to win a prize. As shown in FIGS. 5 and 6, each includes a frame body 71, an opening / closing member 80, a lock member 90, a first torsion spring 73, and a second torsion spring 75. The two opening / closing units 70 of the embodiment have the same configuration. Therefore, hereinafter, only one opening / closing unit 70 arranged in the front side ball passage 43 will be described, and the description of the other opening / closing unit 70 arranged in the front side ball passage 44 will be omitted.

As shown in FIG. 6, the opening / closing member 80 includes an opening / closing member main body 81, a cylindrical rotating cylinder 82 formed on the upper part of the opening / closing member main body 81 so as to extend to the left and right in FIG. 5, and an opening / closing member. A guide surface 83 that is formed so as to extend to the left and right at the lower and front ends of the main body 81 and is inclined downward from one end (left end) to the other end (right end), and a protrusion that protrudes forward from the guide surface 83. It has a portion 84 and a flat working surface 85 formed on the back surface of the opening / closing member main body 81.

The rotary cylinder 82 is inserted into a rotary shaft 72 attached to the frame 71 so as to extend horizontally, and the opening / closing member 80 swings back and forth with respect to the frame 71 with the rotary cylinder 82 as a fulcrum. It is possible to move.

When the opening / closing member 80 swings forward, as shown in FIG. 9A, the guide surface 83 projects toward the front side of the game board 3 and is exposed in the front side ball passage 43. As a result, the opening / closing member 80 is opened. When the opening / closing member 80 is in the open state, the game ball flowing down the front side ball passage 43 flows into the guide surface 83 and is guided by the guide surface 83 to win a prize in the winning opening 61.

On the other hand, when the opening / closing member 80 swings backward, the guide surface 83 is stored on the back side of the game board 3 as shown in FIG. 9B. As a result, the opening / closing member 80 is closed. When the opening / closing member 80 is closed, the game ball flowing down the front side ball passage 43 cannot flow into the guide surface 83, so that the winning opening 61 is not won. In this way, the opening / closing unit 70 is a slide type (bello type) that opens / closes the winning opening 61 by causing the guide surface 83 to appear in the front / rear (front and back) with respect to the game board 3 due to the swing of the opening / closing member 80. It is configured as an opening / closing unit.

As shown in FIG. 6, a first torsion spring 73 is inserted through the rotating shaft 72. As shown in FIGS. 7 (c) and 8 (c), in the first torsion spring 73, one spring foot is locked to the opening / closing member main body 81 of the opening / closing member 80, and the other spring foot is attached to the frame body 71. It is locked and urges the opening / closing member 80 counterclockwise in the drawing. As a result, the opening / closing member 80 is urged rearward (the back side of the game board 3, that is, in the closed state) by the urging force of the first torsion spring 73.

As shown in FIGS. 7 (b) and 8 (b), the projecting portion 84 is formed so as to project upward from the guide surface 83 in a substantially C shape in a side view. When the opening / closing member 80 swings forward and becomes open, the protruding portion 84 retracts from the path from the front side ball passage 42 to the winning opening 61 and is located in the elongated hole 46, and the opening / closing member 80 swings backward. When it is moved and closed, it advances into the route toward the winning opening 61, blocks the winning opening 61, and prevents the game ball from entering the winning opening 61.

The working surface 85 appears and disappears from the elongated hole 32 of the base 30 with respect to the back side ball passage 51 due to the swing of the opening / closing member 80. When the opening / closing member 80 swings forward and becomes open, the working surface 85 becomes substantially flush with the inner surface of the rear side ball passage 51, and the opening / closing member 80 swings backward. When it is moved to a closed state, it is in a state of protruding into the back side ball passage 51. When the game ball enters the entrance 41 and flows down the back side ball passage 51 in the closed state, the game ball collides with the operating surface 85 protruding into the back side ball passage 51, and the weight of the game ball causes the game ball to collide with the operating surface 85. The working surface 85 is pressed. As a result, the opening / closing member 80 is swung forward and displaced from the closed state to the open state.

The lock member 90 locks (holds) the opening / closing member 80 in an open state, and is arranged below the opening / closing member 80. As shown in FIG. 6, the lock member 90 is a flat plate-shaped lock member main body 91 arranged in the horizontal direction, and a rotary cylinder formed so as to extend to the left and right at the rear end portion of the lock member main body 91. From the guide surface 93 formed at the right front end of the lock member main body 91 so as to be adjacent to the right side (the other end of the guide surface 83) of the guide surface 83 of the opening / closing member 80, and the upper surface of the lock member main body 91. It has a lock piece portion 94 that protrudes upward.

The guide surface 93 is inclined so as to descend from the front to the rear, and a winning opening 61 is arranged behind the guide surface 93. As a result, the game ball that has passed through the guide surface 83 flows into the guide surface 93, is guided by the guide surface 93, and enters the winning opening 61.

The rotating cylinder 92 is inserted through a rotating shaft 74 attached to the frame body 71 so as to extend in the horizontal direction, and the lock member 90 moves up and down with respect to the frame body 71 with the rotating cylinder 92 as a fulcrum. Can swing to. As shown in FIG. 6, a second torsion spring 75 is inserted through the rotating shaft 74. As shown in FIGS. 7 (c) and 8 (c), in the second torsion spring 75, one spring foot is locked to the lock member main body 91 of the lock member 90, and the other spring foot is attached to the frame body 71. It is locked and urges the lock member 90 clockwise in the figure. As a result, the lock member 90 is urged upward by the urging force of the second torsion spring 75.

When the lock member 90 is urged upward by the urging force of the second torsion spring 75 and the opening / closing member 80 is in the open state of swinging forward, the back surface of the game board 3 is on the bottom surface of the opening / closing member 80. The lock piece portion 94 of the lock member 90 fits into the stepped portion 86 having a wall surface facing the side. As a result, the opening / closing member 80 cannot swing backward and is locked in the open state. When the opening / closing member 80 is in the open state, when the game ball flowing into the guide surface 83 flows out to the guide surface 93 through the guide surface 83, the lock member 90 becomes the urging force of the second torsion spring 75 due to the weight of the game ball. It is swung downward against it. As a result, the fitting between the lock piece portion 94 and the stepped portion 86 of the opening / closing member 80 is released, and the opening / closing member 80 is swung backward by the urging force of the first torsion spring 73 to be in a closed state. When the opening / closing member 80 is not in the open state, the tip of the lock piece portion 94 abuts on the surface (convex curved surface curved back and forth) in front of the step portion 86 on the bottom surface portion of the opening / closing member 80, so that the opening / closing member 80 is in contact with the opening / closing member 80. 80 is not locked.

The operation of the winning device 20 of the embodiment configured in this way will be described. In the winning device 20 of the embodiment, when the opening / closing member 80 is in the closed state, the entry ball 41 is opened, and when the game ball enters the opened entry opening 41, the entering game ball is on the back side. It is distributed to either the ball passage 51 or the back side ball passage 52, and flows down the distributed back side ball passage. When the game ball flows down the back side ball passage 51, the game ball collides with the operating surface 85 of the opening / closing member 80 protruding into the back side ball passage 51, and the operating surface 85 is pushed by the weight of the game ball to open / close. The member 80 is swung forward. As a result, the guide surface 83 of the opening / closing member 80 projects into the front side ball passage 42 on the front side of the game board 3, so that the opening / closing member 80 is in an open state (a winning state). The opening / closing member 80 is held in an open state by fitting the lock piece portion 94 of the lock member 90 into the stepped portion 86 on the bottom surface portion of the opening / closing member 80.

When the opening / closing member 80 is in the open state and the game ball that has not entered the ball entry port 41 flows down the front side ball passage 42, the game ball flows into the guide surface 83 protruding into the front side ball passage 42. Then, the inflowing game ball rolls on the guide surface 83 (inclined surface), flows out from the guide surface 83, and flows into the guide surface 93 of the lock member 90. Then, the game ball that has flowed into the guide surface 93 is guided by the guide surface 93 (inclined surface) and enters the winning opening 61. When the game ball passes through the guide surface 93, the guide surface 93 is pressed by the weight of the game ball, and the lock member 90 swings downward. As a result, the fitting of the lock piece portion 94 of the lock member 90 and the stepped portion 86 of the opening / closing member 80 is released, and the opening / closing member 80 swings backward due to the urging force of the first torsion spring 73. When the opening / closing member 80 swings backward, the guide surface 83 is stored on the back side of the game board 3, whereby the opening / closing member 80 is in a closed state (a winning state is not possible). The opening / closing member 80 is held in the closed state by the urging force of the first torsion spring 73.

In the winning device 20 of the above-described embodiment, when a game ball enters a ball entry port 41 different from the winning openings 61 and 62, the weight of the entered game ball overcomes the urging force of the first torsion spring 73. When the guide surface 83 is projected toward the front surface side of the game board 3, the opening / closing member 80 is in an open state (a winning state is possible), and the opening / closing member 80 is urged by the second torsion spring 75 (a lock member 90 (a winning state). It is held in the open state by the lock piece 94). Then, when the game ball flows into the guide surface 83 of the opening / closing member 80, the flowing game ball passes through the guide surface 93 of the lock member 90 via the guide surface 83 and enters the winning opening 61 (winning opening 62). .. When the game ball passes through the guide surface 93, the weight of the game ball overcomes the urging force of the second torsion spring 75, so that the lock member 90 is unlocked and the opening / closing member 80 is held in the open state. It will be released. Then, the opening / closing member 80 is closed (a winning impossible state) by retracting the guide surface 83 on the back surface side of the game board 3 by the urging force of the first torsion spring 73. As described above, the opening / closing member 80 has the guide surface 83 of the game board 3 due to the entry of the game ball into the entry openings 41 different from the winning openings 61 and 62 and the entry of the game ball into the winning openings 61 and 62. It is configured to appear on the front side and the back side of the. This makes it possible to obtain a non-electric winning device having a simple configuration and capable of making the device smaller.

Moreover, in the winning device 20 of the embodiment, the opening / closing member 80 is provided in front of the game board 3 with respect to the guide surface 83, and the prize opening of the game ball is stored in the state where the guide surface 83 is stored on the back side of the game board 3. A protrusion 84 that is located on the path to and regulates the entry of the game ball into the winning opening 61 (winning opening 62) is provided. As a result, with the guide surface 83 of the opening / closing member 80 stored on the back side of the game board 3, the game ball directly wins the winning opening 61 (winning opening 62) without passing through the guiding surface 83. Can be stopped.

In the above-described embodiment, after the opening / closing member 80 is opened, when one game ball enters the winning opening 61 (winning opening 62), it is configured to be displaced to the closed state. When two or more game balls enter the winning opening 61 (winning opening 62), the game ball may be configured to be displaced to the closed state. 10 is an exploded perspective view of the opening / closing unit of the modified example, FIG. 11 is an exploded perspective view of the holding mechanism, and FIG. 12 is a front view of the opening / closing unit of the modified example, its DD cross-sectional view, and E. -E is a cross-sectional view.

As shown in FIG. 10, the opening / closing unit 170 of the modified example includes a holding mechanism 200 in addition to the frame body 71, the opening / closing member 80, the first torsion spring 73, the lock member 90, and the second torsion spring 75.

The holding mechanism 200 is a mechanism for holding the opening / closing member 80 in the open state until two game balls enter the winning opening 61 (winning opening 62) after the opening / closing member 80 is displaced to the open state. It is rotatably supported by a rotating shaft 172 attached to the inner surface of the body 71 in a cantilevered state. The holding mechanism 200 has a claw member 210, a gear member 220, and a reverse rotation restricting member 230.

As shown in FIG. 11, the claw member 210 includes an annular claw member main body 211 inserted through a rotating shaft 172, a protrusion 212 protruding axially from the side surface of the claw member main body 211, and an outer periphery of the claw member main body 211. It has a ratchet claw portion 213 extending in a crank shape in the circumferential direction from the surface. The gear member 220 is arranged between the claw member 210 and the opening / closing member 80, and has a predetermined distance (90 °) between the annular gear member main body 221 inserted through the rotating shaft 172 and the outer peripheral surface of the gear member main body 221. A plurality of (4) ratchet teeth 222 formed at intervals) and a rotation shaft 172 from the side surface (side surface on the opening / closing member 80 side) of the gear member main body 221 at a predetermined interval (180 ° interval). It has two abutting portions 223 that project in the axial direction of the above. The claw member 210 and the gear member 220 rotate about the same rotation shaft 172, and the ratchet claw 213 of the claw member 210 engages with the ratchet teeth 222 of the gear member 220. As a result, the claw member 210 is configured as a ratchet mechanism that can rotate relative to the gear member 220 in one rotation direction and cannot rotate relative to the other rotation direction.

In the opening / closing unit 70 of the modified example, the contacted portion 202 protruding in the axial direction is formed on the side surface (side surface on the gear member 220 side) of the opening / closing member main body 81 of the opening / closing member 80. Further, in the opening / closing unit 70 of the modified example, the lock member main body 91 of the lock member 90 is formed with an arm member 201 that engages with the protrusion 212 of the claw member 210. The arm member 201 rotates the claw member 210 counterclockwise in FIG. 12 (b) when the lock member 90 swings downward. At this time, the ratchet claw 213 of the claw member 210 does not mesh with the ratchet teeth 222 of the gear member 220, and the gear member 220 does not rotate integrally with the claw member 210. On the other hand, in the arm member 201, the lock member 90 swings upward to rotate the claw member 210 clockwise in FIG. 12 (b). At this time, since the ratchet claw 213 of the claw member 210 meshes with the ratchet teeth 222 of the gear member 220, the gear member 220 rotates integrally with the claw member 210. As a result, the gear member 220 rotates clockwise in FIG. 12C by a predetermined angle each time the lock member 90 swings up and down. That is, each time the lock member 90 swings up and down, the contact portion 223 of the gear member 220 moves by a predetermined angle in the circumferential direction. When the opening / closing member 80 is swinging forward (open state), the contact portion 223 of the gear member 220 is located rearward in the swing direction of the opening / closing member 80, and the contact portion 223 is hit. By abutting on the contact portion 202, the open state is maintained.

The reverse rotation control member 230 includes a reverse rotation control member main body 231 whose base end is inserted through the rotation shaft 172, a protrusion 232 protruding from the reverse rotation control member main body 231 in the axial direction of the rotation shaft 172, and a reverse rotation control member main body 231. It has a contact portion 233 formed at a base end portion thereof, and a ratchet claw 234 extending like a crank from the tip end portion of the reverse rotation restricting member main body 231. The reverse rotation regulating member 230 is arranged side by side with the claw member 210 on the side opposite to the gear member 220 in the axial direction, and the protrusion 232 is fitted into a recess (not shown) formed on the inner surface of the frame body 71. As a result, the reverse rotation regulating member 230 is fixed to the frame body 71 so as not to rotate. Further, in the reverse rotation restricting member 230, the contact portion 233 abuts on the protrusion 212 of the claw member 210 to regulate the rotation range of the claw member 210, and the ratchet claw 234 engages with the ratchet teeth 222 of the gear member 220. By doing so, the reversal of the gear member 220 is restricted.

13 to 16 are explanatory views showing the operation of the opening / closing unit of the modified example. In the opening / closing unit 170 of the modified example, as shown in FIG. 13, after the opening / closing member 80 is in a state of swinging forward (open state), the first game ball is the guide surface 83 of the opening / closing member 80. When the game ball flowing into the guide surface 83 and flowing out from the guide surface 83 flows into the guide surface 93 of the lock member 90, the guide surface 93 is pushed by the weight of the game ball, and the lock member 90 is swung downward (see FIG. 13). ). At this time, the fitting between the lock piece portion 94 of the lock member 90 and the step portion 86 formed on the bottom surface portion of the opening / closing member 80 is released, while the phase of the contact portion 223 of the gear member 220 is the phase of the opening / closing member 80. It coincides with the contacted portion 202. As a result, the contacted portion 202 is supported by the abutting portion 223, and the opening / closing member 80 is held in the open state. Then, when the game ball passes through the guide surface 93 and the lock member 90 swings upward due to the urging force of the second torsion spring 75, the ratchet claw 213 and the ratchet tooth 222 mesh with each other, and the gear member 220 together with the claw member 210. In FIG. 14, it rotates clockwise. As a result, the contact portion 223 is displaced to a phase different from that of the contacted portion 202, and at the same time, the lock piece portion 94 of the lock member 90 fits with the step portion 86 on the bottom surface portion of the opening / closing member 80, so that the opening / closing member 80 Is held in the open state (see FIG. 14). In this way, even if the first game ball is inserted into the winning opening 61 after the opening / closing member 80 is opened, the opening / closing member 80 is held in the open state.

Next, when the second game ball flows into the guide surface 83 of the opening / closing member 80 and the game ball flowing out from the guide surface 83 flows into the guide surface 93 of the lock member 90, the guide surface 93 is moved by the weight of the game ball. When pressed, the lock member 90 is swung downward (see FIG. 15). At this time, the fitting between the lock piece portion 94 of the lock member 90 and the stepped portion 86 on the bottom surface portion of the opening / closing member 80 is released, and the contact portion 223 of the gear member 220 and the contacted portion 202 of the opening / closing member 80 are brought into contact with each other. The phases do not match either. Therefore, the opening / closing member 80 swings backward due to the urging force of the first torsion spring 73, is displaced to the closed state, and is held in the closed state (see FIG. 16).

In the above-described embodiment, the winning device 20 includes two winning openings 61 and two opening / closing units 70, but the number of winning openings and opening / closing units may be one, respectively. It may be one or more.
