Description

  The present invention relates to a gaming machine frame unit having a rail unit that serves as a guide for a game ball launched toward a game board.

  In a pachinko machine, a ball that has been bulleted flows down a game area (an area formed on or near the game board surface for realizing a game or production by the flow of the game ball). In the process of flowing down, the game ball rolls while colliding with a game nail (also referred to as gauge) or impeller in the game area, and the flow direction changes. As a result, if a game ball wins at various winning holes arranged on the game area, a predetermined winning ball is paid out. On the other hand, if a game ball flows into the out port without winning any of the winning holes, the winning ball Will not be paid out. The player enjoys the game by demonstrating his / her skill in the ball or using the chance of the game ball flowing down and expecting the game ball to be won and paid out.

  Such a pachinko machine is equipped with various game parts such as a game board provided with a game area and a launching device for launching a game ball into the game area, and these game parts are mounted on a game machine frame unit. . For example, the gaming machine frame unit is an outer frame that surrounds the periphery of the pachinko machine, a front frame that is swingably supported by a hinge so that it can be opened and closed forward by a hinge, and a front frame that can be opened and closed by a hinge in front of the front frame. And a glass frame for holding a glass and a decorative member for decorating the periphery of the glass.

  Such a game board is provided with a rail member that guides a game ball launched by the launching device, and the game ball launched by the launching device is guided to the game region along the rail member and is played by the game region. It is configured to flow down inside. For this rail member, a method has been used for a long time in which a belt-like metal thin plate is bent in accordance with the set shape of the game area and is driven into the board surface of the game board and fixed.

  However, in the conventional gaming machine in which the rail member is driven and fixed to the board surface of the game board, if the rail member is deformed for some reason, it is practically impossible to replace only the deformed rail member. Yes, the entire game board had to be replaced. In view of such a problem, a gaming machine configured so that only the rail member can be easily replaced is provided (see Patent Document 1).

  The gaming machine described in Patent Document 1 is configured such that a game board is mounted from the rear and a front rail is mounted from the front of the front frame having a game area opening penetrating in the front-rear direction. . The outer rail has a rail portion formed in accordance with the contour shape of the peripheral edge of the game area opening, and a flange portion that is bent at a right angle from the front end of the rail portion and opens outward. The rail member is fixed with screws in a state in which the rear surface of the flange portion is in contact with the front surface of the front frame, and is configured to be detachable from the front surface side of the front frame.

JP 2008-79761 A

  However, in the gaming machine described in Patent Document 1, the outer rail in which the rail portion and the flange portion are integrated is attached to the front frame, so that depending on the contour shape of the game area opening, it is arranged in close contact with the contour shape. It becomes difficult to do so, and the rail portion serving as the guide surface of the game ball may be distorted or partially lifted, which may reduce the accuracy of game ball launch.

  The present invention has been made in view of the above problems, and in a gaming machine frame unit configured so that rail members can be easily replaced, a gaming machine frame capable of more effectively increasing the accuracy of game ball launching. It is an exemplary task to provide a unit.

  A gaming machine frame unit as an exemplary aspect of the present invention includes a game board that realizes a game by flowing down a game ball, a frame body in which an opening communicating in the front-rear direction is formed, and to which the game board is attached, and a frame body A launching device for launching a game ball toward the surface of the game board, which is disposed below the game board attached to the game board, and a rail that is disposed along the opening and guides the game ball launched toward the game board The rail unit has a plate-like rail member disposed along the opening, and a fixture that detachably fixes the rail member to the frame body, and the rear The frame is provided with a support portion that is formed along the opening and supports the front surface of the rail member, and an engagement portion that engages with the fixture. The fixture is in contact with the rear surface of the rail member By engaging with the engaging portion, the rail member is sandwiched in cooperation with the frame, and when the game board is attached to the frame, the rear surface of the rail member and the game board The front face is disposed so as to face the front, and the game ball launched on the game board moves along the rail member.

  The frame is formed with an opening penetrating in the front-rear direction, and a game board for realizing a game by the flow of game balls is attached from the rear. On the surface of the game board, a game area for realizing a game by the flow of the game ball is formed, and the player can visually recognize the game area through the opening. A launching device is disposed below the game board, and a game ball launched by the launching device is guided to the game area along the rail member of the rail unit.

  The rail unit has a plate-like rail member disposed along the opening, and a fixture for detachably fixing the rail member to the frame, and is configured to be detachable from the frame. ing. By configuring the rail unit so as to be detachable with respect to the frame, it is possible to easily and quickly replace the rail unit when the rail member is damaged.

  The rail member of the rail unit is a plate-like member and can be disposed along an opening that surrounds the game area. By arranging the plate-like rail member along the periphery of the opening, it can be arranged along the contour shape of the opening as compared to a curved rail member which is a molded product like a conventional outer rail. The rail member can be prevented from being partially lifted, and the rail member can be disposed in close contact with the contour shape of the opening. Therefore, it is possible to prevent a drop in launch accuracy due to partial lifting of the rail member, and to stabilize the ball flight.

  Moreover, the rail member is configured such that the front surface thereof is supported by the frame body, and the rear surface thereof is in contact with the fixture, and is sandwiched between the frame body and the fixture. By sandwiching the rail member between the frame and the fixture, the stability of the rail member can be increased, and a reduction in the firing accuracy due to the displacement of the rail member can be suppressed.

  Further, the rail unit is mounted from the rear side of the frame body, and the game board is detachably mounted from the rear side of the frame body to which the rail unit is mounted. Both the rail unit and the game board can be mounted, and the efficiency of the mounting work on the frame can be improved.

  A notch for accommodating the fixture is formed on the back surface of the rail member. When the rail member is fixed to the frame by the fixture, the rear surface of the fixture and the rear surface of the rail member are substantially the same surface. You may comprise so that it may become.

  The rear surface of the rail member is in contact with the fixture, and the rail member is attached to the frame body by the fixture. Further, in a state where the game board is attached to the frame, the rear surface of the rail member and the surface of the game board are arranged to face each other so that the game ball launched to the game board is guided by the rail member. It is configured. In order to guide the game ball launched onto the game board by the rail member, it is desirable to arrange the rail member and the game board in close proximity.

  However, a fixture is in contact with the rear surface of the rail member, and a gap may be formed between the rear surface of the rail member and the surface of the game board depending on the thickness of the fixture. If there is a gap between the rear surface of the rail member and the surface of the game board, the game ball launched on the game board and the rail member cannot be placed close to each other, and the game ball is smoothly directed toward the game area by the rail member. May not be able to lead to

  In order to solve such a problem, the rail member is provided with a notch for accommodating the fixture, and the rear surface of the fixture and the rear surface of the rail member are configured to be substantially flush with each other when the fixture is mounted. It is desirable. According to such a configuration, the rail member and the game board are arranged close to each other, or the rail member and the game board are arranged so as to contact each other. Thus, it is possible to guide appropriately toward the game area.

  Moreover, the inner peripheral surface of the opening has a changing point where the radius of curvature changes, and the fixture may be arranged in the vicinity of the changing point. The opening is formed so as to surround a game area formed in the game board, and its shape corresponds to the shape of the game area. Generally, a gaming machine has a vertically long rectangular shape when viewed from the front, and a gaming board also has a vertically long rectangular shape. In addition, the game area formed on the game board is also a vertically long ellipse, and the opening is configured by combining a plurality of arcs of curvature radii when viewed from the front.

  If the curvature radius of the opening changes in this manner, the rail member arranged along the opening partially rises, and the firing accuracy may be reduced. However, by mounting the fixture near the change point, the rail member can be disposed in close contact with the inner peripheral surface of the opening, and the stability of the ball jump can be improved.

  The rail member may be divided into a first rail member and a second rail member. Compared with the configuration in which one rail member is arranged along the opening by dividing the first rail member and the second rail member, the rail member is easily arranged along the inner peripheral surface. It is possible to improve the adhesion of the rail member and to improve the firing accuracy.

  Further, when the rail member is used for a long period of time, the surface of the rail member may be peeled off or the rail member may be damaged, and the rail member may be replaced. At this time, by constituting with a plurality of rail members, it is possible to replace only the portion that needs to be replaced, and it is possible to shorten the repair process and reduce the repair cost.

  Furthermore, the collision mode of a game ball changes with places, such as a part where a game ball hits vigorously according to the installation location, a part which hits many, etc., and required intensity | strength and surface processing differ. If the rail member is composed of a single member, the entire rail member must be manufactured in accordance with the part that requires the most strength, and the weight becomes excessively heavy, or the processing process takes time. The cost may increase. However, by dividing the rail member, the weight of the entire rail member can be reduced and the manufacturing cost can be reduced.

  The first guide rail may be configured so as to include a first seating point on which a game ball launched on the game board first hits. Since the game ball fired by the launching device moves upward from below, it has the most momentum immediately after being launched, and as it moves along the rail member, the momentum decreases and reaches the gaming area Is configured to do. The impact caused by the collision of the game ball is the largest on the portion (first seating point) where the game ball launched by the launching device hits first.

  By configuring so that the first seating point is disposed on the first rail member, the strength of the first rail member on which the highest impact acts is increased, and damage to the first rail member due to the collision of the game ball is prevented. Can do. Examples of the configuration for increasing the strength of the rail include a configuration in which the first rail member is made of a material having a relatively high strength and the thickness of the first rail member is increased.

  One of the first rail member and the second rail member may be configured to be provided with a pressing portion that covers the rear surface of the other and is disposed with the other in the front-rear direction together with the frame. In the configuration in which the rail member is divided into a plurality of parts, if the positional deviation between the rail members occurs, there is a risk that the stability of the ball skipping is lowered. However, by providing at least one engaging portion that engages with the other, it is possible to prevent the positional deviation between the rail members and realize stable ball skipping.

  Further objects and other features of the present invention will become apparent from the preferred embodiments described below with reference to the accompanying drawings.

  According to the present invention, since the rail unit is configured to be detachable with respect to the frame body, it is possible to easily and detachably replace when the rail member is damaged. Further, by arranging the plate-like rail member along the peripheral edge of the opening, the plate-like rail member is arranged along the contour shape of the opening as compared with a curved rail member which is a molded product like a conventional outer rail. It is possible to prevent the rail member from being partially lifted, and the rail member can be disposed in close contact with the contour shape of the opening. Therefore, it is possible to prevent a drop in launch accuracy due to partial lifting of the rail member, and to stabilize the ball flight.

  Moreover, the rail member is configured such that the front surface thereof is supported by the frame body, and the rear surface thereof is in contact with the fixture, and is sandwiched between the frame body and the fixture. By sandwiching the rail member between the frame and the fixture, the stability of the rail member can be increased, and a reduction in the firing accuracy due to the displacement of the rail member can be suppressed.

In FIG. 8, for convenience of explanation, the game board 6 is omitted, but the inner rail 17 and the shock absorber 18 provided on the game board 6 are indicated by dotted lines, and the launcher 51 of the launch unit 50 and A guide wall surface 54a of the cover member 54 is indicated by a dotted line.

  P1 to P4 shown in FIG. 8 are changing points at which the radius of curvature of the inner peripheral surface 9c changes. Four changing points are provided from the left end of the front frame 9 along the inner peripheral surface 9c. The radius of curvature of the inner peripheral surface 9c changes with each change point as a boundary. The radius of curvature of the inner peripheral surface 9c from the left end portion to P1 is 51.25, and the radius of curvature of the inner peripheral surface 9c from P1 to P2 is 37.5. The radius of curvature of the inner peripheral surface 9c from P2 to P3 is 70.0. The radius of curvature of the inner peripheral surface 9c from P3 to P4 is 37.5.

  If the curvature radius changes in this manner, the plate-like second rail member 42 cannot be disposed in close contact with the inner peripheral surface 9c, and the firing accuracy may be reduced. However, in the present embodiment, in order to eliminate such a problem, the fixture 43 is mounted near the changing point, and the second rail member 42 is disposed along the inner peripheral surface 9c. The fixing tool 43 is mounted at three locations along the inner peripheral surface 9c from P2 to P3, and is mounted at one location along the inner peripheral surface 9c from the left end portion to P1.

  Thus, by attaching the fixture 43 in the vicinity of the changing point, the second rail member 42 can be disposed in close contact with the inner peripheral surface 9c. Further, when the second rail member 42 is mounted, the fixing member 43 can be mounted in order from the left end portion where the bent portion 42c is provided along the inner peripheral surface 9c. The positional deviation of the two rail members 42 can be prevented, and the firing accuracy can be stabilized.

  Moreover, since the fixing tool 43 is mounted along the inner peripheral surface 9c, it has a different shape depending on the radius of curvature of the inner peripheral surface 9c. By arranging the plurality of fixtures 43 on the inner peripheral surface 9c having the same radius of curvature (P2 to P3), the plurality of fixtures 43 can be formed in the same shape, and the efficiency of the parts can be improved.

  In addition, the alternate long and short dash line in FIG. 8 indicates the trajectory of the game ball 23 bulleted by the launch unit 50. The game ball 23 is configured to be bulleted with various strengths by the launch unit 50, and passes through different trajectories depending on the strength. However, the game balls 23 of any trajectory are configured to collide with the first rail member 41 first (the first rail member includes the first seating point). In this way, by configuring the first rail member 41 to include the first seating point, the durability of the entire rail unit can be maintained by increasing the strength of the first rail member 41.

  In addition, the boundary between the first rail member 41 and the second rail member 42 may cause a gap or a step between the members, and the ball flying stability is reduced when the game ball collides. There is a fear. However, the boundary portion between the first rail member 41 and the second rail member 42 is arranged at a vertically arranged location so that the game ball 23 launched by any strength does not collide. In this manner, by arranging the boundary portion between the first rail member 41 and the second rail member 42, it is possible to minimize the adverse effect on the ball jump due to the step or gap of the boundary portion.

  FIG. 9 is an exploded perspective view of the rail unit 40 in which the fixing member 43 portion arranged in the central portion in the left-right direction is enlarged, and FIGS. 10 and 11 are cross sections in a state where the rail unit 40 is mounted on the front frame 9. FIG. 10 shows an AA cross section shown in FIG. 8, and FIG. 11 shows a BB cross section shown in FIG. 10 and 11, the game board 6 is schematically indicated by a dotted line. The fixture 43 includes a first claw portion 43a that protrudes outward, a second claw portion 43b that protrudes forward, and a projection hole portion 43c into which a cylindrical projection portion 9g that is formed to protrude from the front frame 9 is inserted. Have.

  The first claw portion 43a is configured to be deformable inward by being pressed with a finger or the like from the side, and is configured to be engaged with a claw receiving portion 9f provided on the front frame 9. Yes. In a state where the second claw portion 43b is in contact with the notch portion 42d of the second rail member 42 and the projection portion 9g of the front frame is inserted into the projection hole portion 43c, the first claw portion 43a is engaged with the claw receiving portion 9f. By stopping, the second rail member 42 can be clamped by the fixture 43 and the front frame 9.

  Further, as shown in FIG. 10, in a state where the second rail member 42 is attached to the front frame 9 by the fixture 43, the protruding portion 9 d of the front frame 9 moves along the second rail member 42. It is configured not to collide with. The protruding amount of the protruding portion 9d with respect to the inner peripheral surface 9c is less than the radius of the game ball 23, and is formed to a length that does not contact the game ball 23 that moves along the first rail member 41 and the second rail member 42. Yes. Therefore, it is possible to prevent the movement of the game ball 23 from being inhibited by the protruding portion 9d.

  Next, a method for mounting the rail unit 40 thus configured to the front frame 9 will be described. First, the second rail member 42 is attached to the front frame 9. The bent portion 42c provided at the lower end portion of the second rail member 42 is inserted into the slit portion 9k of the front frame 9, and the plate portion 42b of the second rail member 42 is disposed along the inner peripheral surface 9c.

  Next, the fixture 43 is attached. When the fixing tool 43 is mounted, the side of the fixing tool 43 is pressed with a finger or the like to deform the first claw portion 43a inward, and in this state, the position corresponding to the notch portion 42d of the second rail member 42 is obtained. A fixture 43 is arranged. The fixing tool 43 is moved forward, and the pressing of the fixing tool 43 is released in a state where the second claw portion 43b and the cutout portion 42d are in contact with each other. By releasing the pressing, the deformation of the first claw portion 43a is released, and the first claw portion 43a is engaged with the claw receiving portion 9f of the front frame 9. When the first claw portion 43a is locked to the claw receiving portion 9f, the backward movement of the fixture 43 is restricted, and the fixture 43 and the front frame 9 cooperate to sandwich the second rail member 42, The second rail member 42 can be attached to the frame body 9.

  After mounting the second rail member 42, the first rail member 41 is mounted on the front frame 9. FIG. 12 is an enlarged view of a portion C shown in FIG. 8, and is an enlarged view of a boundary portion between the first rail member 41 and the second rail member 42. The first rail member 41 is arranged along the inner peripheral surface 9c so that the pressing portion 41d of the first rail member 41 is overlapped behind the second rail member 42. And the screw hole part 41e of the 1st rail member 41 and the screw hole part 9h of the front frame 9 are piled up, and these screw hole parts are screwed together by a screw part. By mounting the first rail member 41 in this way, the second rail member 42 can be held between the first rail member 41 and the front frame 9.

  Next, after mounting the rail unit 40, the game board 6 is mounted on the front frame 9. In the present embodiment, the game board 6 is mounted from behind the front frame 9. By mounting the game board 6, the game board surface 6a and the rear surface 42e of the second rail member 42 face each other as shown in FIG. It can be guided by the first rail member 41 and the second rail member 42.
