Description

The present invention, a number of game balls about the shock-absorbing equipment to absorb the impact during collision of the game balls in ball passage or the like for circulation.

  Conventionally, various ball passages through which game balls (pachinko balls) are circulated for supply, withdrawal, discharge, etc. are provided in the pachinko gaming machine and the island facility where a plurality of the pachinko gaming machines are installed. In general, these ball passages are formed of metal or resin, so that when a game ball that circulates in the ball passage collides with the wall surface of the passage, a loud collision sound is generated and A severe shock will be applied. Therefore, as an apparatus for absorbing the impact (and collision sound) at the time of such a collision of game balls, for example, an impact absorbing apparatus (a pachinko ball collision sound reducing apparatus) as described in Patent Document 1 has been proposed. Has been.

The shock absorbing device of Patent Document 1 is installed in a prize ball payout passage in a pachinko gaming machine or a cage in a pachinko ball distributing device in an island facility, and its surface functions as a collision surface for a game ball. A plate-shaped impact absorbing member made of a polyurethane elastomer or the like is provided. When the ball is installed in the ball path (the prize ball payout path or the basket), the impact absorbing member is placed on the wall surface of the path on which the game ball collides, and the impact ball is a collision surface of the game ball. It is configured to be attached with a support member (for example, a spacer or the like) interposed so that a gap is formed between the back surface of the absorbing member and the passage wall surface. That is, when a game ball collides with the surface (impact surface) of the impact absorbing member, the impact absorbing member bends and vibrates within the gap, thereby causing an impact (and collision sound) based on the collision of the game ball. It was supposed to absorb (decay).
Japanese Patent Laid-Open No. 10-309358 (Claim 1, paragraph number [0008], FIG. 1)

  However, in the impact absorbing device described in Patent Document 1, the impact absorbing member is made of a polyurethane-based elastomer. Therefore, when a game ball collides with the surface (collision surface) of the shock absorbing member, the polyurethane elastomer has a relatively high friction coefficient, so that frictional heat is generated at the surface portion where the game ball collides. . Therefore, when a large number of game balls repeatedly collide with the same surface portion of the shock absorbing member over a long period of time, the surface portion may gel due to the frictional heat, and the surface may be gradually scraped and lost. It was. In addition, for such defects, the coefficient of friction further increases, so the degree of defects gradually increases, and eventually a through hole penetrating from the front side to the back side is formed. There was a problem that it was impossible to absorb the impact (collision sound) based on the collision of the game balls.

The present invention has been made in view of such circumstances, and its object is to provide a shock-absorbing equipment impact based on the collision of the game ball (and collision sound) it can be surely absorbed over time .

The coefficient of friction in the atmosphere Coated at a lower material of the face material than, the surface of the face material is configured as a collision surface with the game balls, the impact absorbing member is formed with a recess in the plate or the back side In addition, a displacement space is provided on the back side of the pressure receiving surface to allow the shock absorbing member to be displaced toward the back side when the pressure receiving surface receives an impact load from a game ball colliding with the collision surface. In addition, when the shock absorbing member has a plate shape , the displacement space is formed by placing the shock absorbing member on the pressure receiving surface side of the shock absorbing member with respect to the substrate formed with a spacer or a recess formed in a rectangular frame shape. In the case where the shock absorbing member is formed so as to have a recess on the back surface side, the shock absorbing member is attached to the flat substrate.

(First embodiment)
Hereinafter, a first embodiment in which the present invention is embodied in an island facility in which a plurality of pachinko machines are installed will be described with reference to FIGS.

  As shown in FIG. 1, the island facility 10 of the present embodiment includes a ball lifting device 11 in the approximate center of the island facility 10 in the longitudinal direction (left-right direction in FIG. 1). The ball lifting device 11 lifts the game ball upward while polishing the game ball via a polishing lift (not shown), and stores a large number of game balls at a position corresponding to the upper end of the ball lifting device 11. Possible island tanks 12 are installed. A plurality of (for example, 10) pachinko machines (game machines) 13 are installed in parallel on the left and right sides of the ball lifting device 11, respectively. In the upper area of each pachinko machine 13, a ball supply rod 14 for distributing and supplying game balls stored in the island tank 12 to the respective pachinko machines 13 has the ball lifting device 11 side as an upstream end. A pair of left and right is provided in an oblique state. A plurality of ball distribution chutes (not shown) are branched from each ball supply basket 14 so as to individually correspond to each pachinko machine 13, and game balls are distributed and supplied to each pachinko machine 13 via each distribution chute. It has come to be.

  On the other hand, in the lower area of each pachinko machine 13 in the island facility 10, a ball collection basket (ball passage) 15 for collecting game balls (for example, out balls) discharged from the respective pachinko machines 13 is provided for the balls. A pair of left and right is provided in an oblique state with the lifting device 11 side as the downstream end. Then, the game balls are discharged from each pachinko machine 13 to a ball collection basket 15 located below via a ball discharge chute (not shown). These left and right ball collection baskets 15 each have a downstream end portion serving as a game ball discharge end covered with a cover 16 (see FIG. 2), and each downstream end thereof is substantially the center of the island facility 10. And extends to the inside of the ball collection tank 17 installed at a position corresponding to the lower end of the ball lifting device 11. Therefore, the game balls discharged from the respective pachinko machines 13 into the ball collection basket 15 flow down in the ball collection basket 15 toward the downstream end, and vigorously enter the ball collection tank 17 from the downstream end. Will be released. Further, a communication port 20 communicating with a ball intake port (not shown) of the ball lifting device 11 is formed in the lower center of the ball collection tank 17 (see FIG. 2). Therefore, the game balls released into the ball collection tank 17 are taken into the ball lifting device 11 through the communication port 20 and the intake port and are transported to the island tank 12. .

  As shown in FIG. 2, the ball collection tank 17 is a box that opens upward, and the upper opening is closed by a lid 18 for preventing the game balls from splashing out of the ball collection tank 17. ing. A guide device 19 having a substantially rectangular parallelepiped shape is suspended from the inner surface of the lid 18, and this guide device 19 is a game released into the ball collection tank 17 from the downstream ends of the left and right ball collection baskets 15. It is arranged so as to be located on the discharge trajectory of the sphere and just above the communication port 20. Therefore, the game balls released from the downstream end of each ball collection basket 15 are on the surface (specifically, the surface 25a of the cover material 25 described later) facing the downstream end of each ball collection basket 15 in the guide device 19. It will collide. Then, the game ball that has collided with the surface of the guide device 19 (the surface 25a of the cover material 25) is absorbed by the guide device 19 and falls directly below. Accordingly, the guide device 19 changes the jumping direction (falling direction) of the game ball released from the downstream end of the ball collection basket 15 and moves the game ball to the communication port 20 side (of the ball collection tank 17). It guides toward the lower center) (see FIG. 4).

Next, a specific configuration of the guide device 19 will be described with reference to FIG.
As shown in FIG. 3, the guide device 19 includes two plate-shaped impact absorbing members 21 made of an elastic material (in this embodiment, polyurethane elastomer). A spacer 22 having a rectangular frame shape is interposed therebetween. Then, each shock absorbing member 21 is assembled and fixed to the spacer 22 via a plurality of screws 23, and there is a predetermined gap between the two shock absorbing members 21 (that is, the back side of each shock absorbing member 21). A volume air layer 24 is formed as a displacement space that allows displacement of each shock absorbing member 21 toward the back surface side.

  Therefore, when the game balls released into the ball collection tank 17 from the downstream ends of the ball collection baskets 15 collide with the surface of the guide device 19 (the surface 25a of the cover material 25), each shock absorbing member 21 is In response to an impact load from the game ball, it bends and vibrates within the air layer 24. In the guide device 19, the impact absorbing member 21 is curved and vibrated as described above, thereby absorbing (attenuating) an impact (and a collision sound) based on the collision of the game balls. Therefore, in this embodiment, the guide device 19 including the shock absorbing member 21 also functions as a shock absorbing device.

  Further, in the guide device 19, each surface 21 a on the surface side of each shock absorbing member 21 is covered and protected by a surface covering material 25 having air permeability. The covering material 25 is made of nylon woven fabric, and more specifically, is a cloth made by weaving synthetic nylon fibers, and a minute air layer is formed between the fibers. Therefore, it has air permeability. The cover material 25 is fixed with a plurality of screws 27 (only two are shown in FIG. 3) with a cloth pressing plate 26 interposed between the spacers 22. When a game ball is released from the downstream end of each ball collection basket 15 into the ball collection tank 17, the game ball collides with the surface 25a of the cover material 25 so that the direction of flight is guided. It has become. Therefore, in this embodiment, the surface 25a of the cover material 25 in the guide device 19 is configured as a collision surface with the game ball, and the surface side 21a of the shock absorbing member 21 covered and protected by the cover material 25 is provided. Is configured to function as a pressure receiving surface that receives an impact load from a game ball.

  In the present embodiment, when the ambient temperature is 25 degrees, the shock absorbing member 21 has a friction coefficient of about 3.5, while the outer cover 25 has a friction coefficient of the shock absorbing member 21. It is comprised with the nylon which is about 0.2 lower than the friction coefficient (about 3.5). Therefore, even if a large number of game balls repeatedly collide with the surface 25a of the surface covering material 25 that becomes the surface of the guide device 19 over a long period of time, the surface covering material 25 has a low coefficient of friction (about 0.2), so that the friction is almost Heat is not generated. Even if the collision with the game ball is repeated and frictional heat is generated, the cover material 25 has air permeability. Therefore, the frictional heat does not stay inside the cover material 25 and quickly flows outside. The heat will be dissipated. Nylon has characteristics such as a low friction coefficient, excellent heat resistance, excellent wear resistance, and excellent self-lubricating properties.

  Then, next, with reference to FIG. 4, an explanation will be given on the operation when the game ball is released into the ball collection tank 17 from the downstream end of the ball collection basket 15 in the island facility 10 of the present embodiment configured as above. To do. In the following description, only the case where a game ball is released from the right ball collection basket 15 into the ball collection tank 17 in FIGS. 1 and 2 will be described. The case where it is released is the same as the case where it is released from the right-side ball collection basket 15, and therefore redundant explanation is omitted.

  Now, as shown in FIG. 4, the game ball B flowing down toward the downstream end in the ball collection basket 15 is released from the downstream end of the ball collection basket 15 into the ball collection tank 17 and released. It collides with the surface of the guide device 19 (the surface 25a of the cover material 25) installed on the trajectory. Then, the game ball B that has collided with the surface of the guide device 19 (the surface 25a of the cover material 25) is changed in its flying direction, and is guided toward the communication port 20 side in the ball collection tank 17.

  Therefore, each game ball B released (collected) into the ball collection tank 17 is not immediately mixed (ie, stayed) in the ball collection tank 17, and the game ball B is promptly released from the communication port 20. It smoothly goes out toward the ball lifting device 11 communicating with the communication port 20. Therefore, the ball lifting device 11 can lift a large number of game balls B to the upper island tank 12 while efficiently polishing them with the polishing lift.

  Further, the guide device 19 is provided within the range of the air layer 24 in which the impact absorbing member 21 is formed on the back surface side by the impact load from the game ball B when the game ball B collides with the surface 25a of the cover material 25. Bends and vibrates. Therefore, in the island facility 10, the impact and the collision sound when a large number of game balls B released from the downstream end of the ball collection basket 15 into the ball collection tank 17 collide with the guide device 19 are generated by the impact absorbing member 21. Absorbed (damped) by bending / vibration and reduced well.

  When the game balls B collide with each other in the guide device 19, the cover material 25 that directly rubs against the game balls B is made of a nylon material having a lower friction coefficient than the shock absorbing member 21 in the same temperature atmosphere. ing. Therefore, frictional heat generated when the game ball B collides can be suppressed, and even if a large number of game balls B repeatedly collide with the collision surface of the guide device 19 (the surface 25a of the cover material 25) for a long time, the shock absorbing member The surface 21a on the surface side 21a is not gelled and missing (for example, a hole is opened). Therefore, the guide device 19 that also functions as an impact absorbing device can avoid the loss due to the impact absorbing member 21 being collided with the game ball B, and can maintain the impact absorbing function for a long period of time.

Therefore, in this embodiment, the following effects can be obtained.
(1) Since one surface (pressure receiving surface) 21a which is the surface side of the shock absorbing member 21 is covered and protected by the cover material 25, even if a large number of game balls B repeatedly collide with the guide device 19, those collisions It is the surface 25 a of the cover material 25 that has a lower coefficient of friction than the impact absorbing member 21, sometimes colliding with the game ball B as a collision surface. Therefore, it is possible to avoid the one surface 21a of the shock absorbing member 21 from being gelled by the frictional heat at the time of collision with the game ball B or being lost due to the gelation. Therefore, the guide device 19 that also functions as an impact absorbing device can reliably absorb the impact (and collision sound) based on the collision of the game ball B over a long period of time.

  (2) When the game ball B collides with the surface (collision surface) 25a of the cover material 25 and an impact load is applied to one surface (pressure receiving surface) 21a of each shock absorption member 21, each shock absorption member 21 Is bent and vibrated within the range of the air layer (displacement space) 24. Therefore, the impact (and collision sound) based on the collision of the game ball B can be reliably absorbed (attenuated) by the bending / vibration of the impact absorbing member 21.

  (3) Since the cover material 25 has air permeability, each of the impacts covered and protected by the cover material 25 or the cover material 25 when a large number of game balls B repeatedly collide with the surface 25a over a long period of time. Even if frictional heat is generated in the absorbing member 21, such frictional heat can be radiated well to the outside.

  (4) Since the covering material 25 is composed of a woven fabric made by weaving long fibers, a fine air layer is formed between the fibers. Therefore, the surface covering material 25 can have air permeability without being subjected to a cutting process or the like. Moreover, since the surface material 25 itself can absorb an impact load because the weave is displaced based on the collision of the game ball B and the minute air layer formed between the fibers functions as a cushion, the durability of the surface material 25 is improved. Can be improved.

  (5) In the island facility 10, particularly in the ball collection tank 17 from which a large number of game balls are discharged from the downstream end of the ball collection basket (ball passage) 15, shock absorption and collision sound due to the collision of the game ball B are absorbed. It can be reduced by the guide device 19 that also functions as a device.

  (6) The game balls B discharged from each pachinko machine 13 and flowing down in the ball collection basket (ball passage) 15 toward the downstream end are vigorously released into the ball collection tank 17 from the downstream end of the ball collection basket 15. The At that time, the released game ball B collides with the collision surface (the surface 25a of the cover material 25) of the guide device 19 provided on the release trajectory of the game ball B, thereby communicating in the ball collection tank 17. Guided toward the mouth 20 side. Therefore, in the ball collection tank 17, a large number of game balls B are not in a mixed state, and can be smoothly let out from the communication port 20 to the ball lifting device 11. The lifting efficiency of the sphere B can be maintained well.

(Second Embodiment)
Next, a second embodiment of the present invention will be described with reference to FIGS. In addition, this embodiment differs in the structure regarding a guide apparatus from 1st Embodiment, and it has the same structure as 1st Embodiment about another structure part. Therefore, in the following description, parts different from those of the first embodiment will be mainly described, and the same or corresponding member configurations as those of the first embodiment are denoted by the same reference numerals, and redundant description will be omitted. .

  As shown in FIG. 5, in the present embodiment, the guide device 19 </ b> A is supported via the bracket 28 on the cover 16 that is the downstream end constituting part of the ball collection basket 15. That is, in the present embodiment, the guide device 19A is arranged so as to form an oblique shape in the vicinity of the downstream end of the ball collecting rod 15 as compared with the case of the first embodiment. Then, when the game ball B released from the downstream end of the ball collection basket 15 collides with the guide device 19A, the direction in which the game ball B jumps out is the same as in the case of the first embodiment. The change guide is directed toward the communication port 20 in the collection tank 17.

Next, a specific configuration of the guide device 19A will be described with reference to FIG.
As shown in FIG. 6, the guide device 19A includes a single plate-shaped impact absorbing member 21 made of an elastic material (polyurethane elastomer) and a base material 29 having a rectangular frame shape. The shock absorbing member 21 is bonded to the surface side of 29 (the right side in FIG. 6). A through-hole 29 a is formed as a displacement space that allows displacement of the shock absorbing member 21 toward the back side inside the base material 29 (that is, the back surface side of the shock absorbing member 21). Also in the guide device 19A of the present embodiment, one surface 21a on the surface side of the impact absorbing member 21 is covered and protected by a cover material 25 made of nylon fabric, and the cover material 25 is formed of the base material. A plurality of screws 27 (only two are shown in FIG. 6) are fixed to the back surface side of 29 with the cloth pressing plate 26 interposed.

  Therefore, as shown in FIG. 7, when the game ball B released into the ball collection tank 17 from the downstream end of the ball collection basket 15 collides with the surface of the guide device 19A (that is, the surface 25a of the cover material 25). The shock absorbing member 21 receives an impact load from the game ball B and bends and vibrates within the depth range of the through hole 29a. Also in this guide device 19A, the impact absorbing member 21 is curved and vibrated in this manner, so that the impact (and the impact sound) based on the collision of the game ball B is absorbed (attenuated). Therefore, also in this embodiment, the guide device 19A provided with the shock absorbing member 21 functions as a shock absorbing device.

  Further, in the guide device 19A, the surface 25a of the cover material 25 is set to be inclined on the discharge trajectory of the game ball B and in the vicinity of the downstream end of the ball collection basket 15. Then, by tilting the surface 25a of the cover material 25 with respect to the horizontal direction in this way, the guide device 19A allows the game ball B immediately after being released into the ball collection tank 17 from the downstream end of the ball collection basket 15 to be removed. It is made to collide with the surface 25a of the surface covering material 25, and the protrusion direction is changed. Therefore, also in this embodiment, the surface 25a of the cover material 25 in the guide device 19A is configured as a collision surface with the game ball B, and one surface on the surface side of the shock absorbing member 21 covered and protected by the cover material 25 21 a is configured to function as a pressure receiving surface that receives an impact load from the game ball B.

Therefore, according to the second embodiment, substantially the same effects as the effects (1) to (6) of the first embodiment can be obtained, and the following effects can also be obtained. .
(7) The guide device 19 </ b> A is disposed so as to be inclined in the vicinity of the downstream end of the ball collection basket 15, and the surface 25 a of the cover material 25 serving as a collision surface is discharged from the downstream end of the ball collection basket 15. It is set to be positioned on the release trajectory of the game ball B. Therefore, the game ball B released from the downstream end of the ball collection basket 15 into the ball collection tank 17 is immediately after being released from the downstream end of the ball collection basket 15, the collision surface (of the cover material 25 It collides with the surface 25 a) and is guided toward the communication port 20 in the ball collection tank 17. Therefore, it becomes easy to control the game ball B in the direction to be guided (the communication port 20 side), and each of the game balls B released from the downstream end of the ball collection basket 15 has different momentum. Each game ball B can be reliably guided to the contact port 20 side by colliding with the collision surface of the guide device 19A (the surface 25a of the outer covering material 25).

  (8) Since the guide device 19 </ b> A is supported on the cover 16, which is the downstream end component part of the ball collection basket 15, via the bracket 28, the first embodiment in which the guide device 19 is suspended and supported on the inner surface of the lid 18. Unlike the case, the ball collection tank 17 having various sizes and shapes such as horizontally long and vertically long can be dealt with. It is also possible to remove the lid 18.

  (9) In the first embodiment, the guide device 19 is installed vertically to absorb almost the momentum of the game ball B that has collided with the collision surface (the surface 25a of the cover material 25). The game ball B was guided (dropped) substantially below (the communication port 20 side). However, in the second embodiment, the guide device 19A is installed so as to form an oblique shape. Therefore, the momentum when the game ball B collides is absorbed to some extent, and can be left slightly. Therefore, the game ball B with a little remaining momentum can use the momentum to enter the contact port 20 of the ball collection tank 17 more smoothly.

Each of the above embodiments may be changed to another embodiment (another example) as follows.
In each of the embodiments, as shown in FIG. 8, the guide device absorbs shock in a state where the frame-shaped spacer 22 is interposed between a single substrate 30 made of wood or the like and the shock absorbing member 21. A guide device 19B may be used in which the member 21 is assembled and fixed to the substrate 30 with screws 23. Even in this configuration, the air layer 24 that allows the shock absorbing member 21 to bend and vibrate is formed on the back surface side of the shock absorbing member 21, so that the game ball B is placed on the collision surface of the guide device 19B. It is possible to reliably absorb impacts and impact sound in the event of a collision.

  In each of the embodiments, as shown in FIG. 9A, the guide device forms the recess 31 a in the substrate 31 made of wood or the like, and attaches the shock absorbing member 21 to the substrate 31 in a mounting manner that closes the recess 31 a. Alternatively, the guide device 19 </ b> C may be assembled and fixed with screws 23. Further, as shown in FIG. 9B, a guide device 19D in which an impact absorbing member 21 having a recess 21b formed on the back surface side is assembled and fixed to a flat substrate 32 made of wood or the like with a screw 23 may be used. Good. Even in such a configuration, since the air layer 24 that allows the shock absorbing member 21 to bend and vibrate is formed on the back surface side of each shock absorbing member 21, the game ball B is provided with each guide device. It is possible to reliably absorb the impact and the collision sound when colliding with the collision surfaces of 19C and 19D.

  In each of the above embodiments, the cover material 25 may be made of a nylon knitted fabric or a nonwoven fabric. When the cover material 25 is formed of a knitted fabric, the impact can be absorbed by the displacement of the stitch of the cover material 25 when the game ball B collides. The material of the cover material 25 may be, for example, a cloth made of synthetic fiber, synthetic leather, or the like as long as the material has a lower coefficient of friction than the impact absorbing member 21 (polyurethane elastomer). However, when the surface covering material 25 is made of synthetic leather, the surface covering material 25 is subjected to cutting processing (for example, making a fine hole smaller than the size of the game ball B) so as to have air permeability. desirable. In addition, it is desirable for the synthetic fiber as a raw material which comprises the surface covering material 25 to have the characteristic substantially the same as nylon, for example, polyester may be sufficient. Polyester has properties such as a low coefficient of friction and excellent wear resistance and self-lubricating properties.

In each of the above embodiments, the impact absorbing member 21 may be an arbitrary elastic material such as rubber or sponge as long as it is an elastic material excellent in impact absorption.
In the above embodiments, the guide devices 19, 19 </ b> A to 19 </ b> D that function as shock absorbers are locations other than those in the ball collection tank 17 as long as the game balls B may collide in the island facility 10. You may install in the place. Further, it may be installed in various ball passages such as a prize ball payout passage (a kind of ball passage) provided in each pachinko machine 13.

  -Moreover, as shown to Fig.10 (a), the guide apparatuses 19 and 19A-19D which function as an impact-absorbing apparatus provide the recessed groove 15b in the side wall part 15a of the ball collection basket 15, and block the said recessed groove 15b. The shock absorbing member 21 may be fixed in the mounting manner. In the guide device 19A shown in FIG. 8, a rib member 33 may be interposed inside the frame-shaped spacer 22 (see FIG. 10B). With this configuration, the shock absorbing member 21 can be prevented from excessively bending / vibrating and coming into contact with the substrate 30, so that the shock absorbing device can be enlarged.

  In the second embodiment, the guide device 19A may be supported so that the inclination of the surface 25a of the surface covering material 25 that is a collision surface with the game ball B with respect to the horizontal direction can be changed. With this configuration, even when the size, shape, or the like of the ball collection tank 17 is changed or the position of the communication port 20 communicating with the ball lifting device 11 is changed, the collision surface (surface display) of the guide device 19A is changed. The guide direction of the game ball B can be easily adjusted by changing the inclination of the surface 25a) of the material 25.

  In the first embodiment, a plurality of (for example, two) guide devices 19 may be provided, and each of the guide devices 19 may be disposed in the vicinity of the downstream end of each ball collecting rod 15. In this case, each guide device 19 is preferably supported so as to form an oblique shape instead of being perpendicular to the inner surface of the lid 18 of the ball collection tank 17.

  In the first embodiment, the guide device may have, for example, a substantially inverted triangular shape when viewed from the side, and two oblique collision surfaces may be formed. Also in this case, the collision surface with the game ball B is constituted by the surface 25 a of the cover material 25, and the shock absorbing member 21 is provided on the back surface side of the cover material 25.
