Description

  The present invention relates to a gaming machine including a game board having a game area in which a game ball such as a pachinko, an arrangement ball, or a sparrow ball can roll, and in particular, can be placed on the floor without falling down. The present invention relates to a gaming machine equipped with a self-supporting device for preventing falling.

  In general, a ball game machine such as a pachinko machine is hinged so that a gaming machine main body can be opened and closed at one side edge of a machine frame (outer frame) of a vertically long rectangular frame, and a transparent plate holding frame ( The glass frame is hinged so that it can be opened and closed. And recently, from the viewpoint of design, both side edges and upper edge of the transparent plate holding frame are greatly extended forward, and a large number of lighting devices and speakers are provided on the extension, depending on the game situation. A gorgeous effect is produced by operating the illumination device. For this reason, the front side of the gaming machine tends to be heavier than the rear side. For example, when installing a new gaming machine in a gaming hall, the gaming machine is temporarily placed on the floor of the gaming hall. There is a problem that it is easy to fall forward, and there is a possibility that the front of the gaming machine may be damaged due to an impact when it falls. Moreover, when the transparent plate holding frame on the front side of the gaming machine is opened, the center of gravity moves further forward and it becomes easier to fall forward. For this reason, there was a problem that it was necessary to work while holding the gaming machine in an unstable state.

On the other hand, Patent Document 1 below discloses a gaming machine in which a fall-preventing leg is hinged so as to be pivotable rearward on the left and right side plates of the machine frame. In the gaming machine, the fall-preventing leg is maximally rearward. By rotating to the rotation angle, it is possible to prevent the vehicle from falling backward.
In Patent Document 2, a support leg is provided at the bottom of the machine frame of the gaming machine so as to be able to rotate backward in a horizontal plane, and after rotating the support leg backward, the tip of the support leg is placed on the floor surface. An apparatus is shown that can prevent the gaming machine from falling backward by sliding downward so that it can be grounded.

  By the way, the machine frame of a pachinko gaming machine is generally vertically long and has a center of gravity at a high position. Therefore, if such a gaming machine is supported by a leg for preventing a fall as shown in Patent Document 1, a safety point of view. The hinge part must be provided as high as possible from the top (high position), and many pachinko gaming machines are arranged on the island base of the game hall without any gaps. In this case, there is a problem that the fall prevention leg obstructs an important space for providing a large game board unit including a liquid crystal display device, a game control device and the like. Further, if such a fall-preventing leg is provided on the front surface of the gaming machine, there is a great risk that it will be manipulated unnecessarily by the player and that the beauty will be impaired.

  In addition, the fall prevention device disclosed in Patent Document 2 also has a problem that if it is provided on the front surface of the gaming machine, it may be operated unnecessarily by the player and the aesthetics are impaired.

A gaming machine equipped with a self-supporting device according to the present invention is intended to solve the above-mentioned problems, and projects forward to the front side of the bottom plate in a vertically long rectangular machine frame comprising a bottom plate, left and right side plates, and a top plate. The curtain plate is pivotally supported so as to be rotatable within a horizontal plane, and a curtain plate lock mechanism is provided so that the unlocking portion is not exposed to the front side of the gaming machine. The curtain plate is held in a non-extending state by a mechanism, and the curtain is unlocked by operating the lock release portion so as to project forward.
Thus, since the curtain is projected forward, it can be provided in the dead space of a conventional gaming machine without impairing the beauty.
In the gaming machine, the curtain plate is urged by an urging member so as to protrude forward, and the lock plate is unlocked by operating the lock release portion. It is characterized by projecting forward by force.
In this way, the urged curtain plate projects forward with a single touch, which simplifies operation.

Further, in the above gaming machine, the present invention is configured such that the curtain plate is configured by connecting a pair of curtain plate pieces divided into left and right so that the curtain plate can bend and extend in a horizontal plane, and a pair of pivot plates that support both ends of the curtain plate. The sliders are arranged so as to be slidable in the horizontal direction along the rails provided in the machine frame, and the sliders are moved closer to each other by operating the lock mechanism so that the curtain plate is V-shaped. It is characterized in that it can be refracted and projected forward.
The curtain is refracted into a V shape and protrudes forward, so that sufficient strength can be obtained, and even a heavy game machine can reliably prevent overturning.
Further, in the above gaming machine, the rack teeth are respectively fixed to the pair of sliders in the horizontal direction, and the pinions engaged with the rack teeth are rotatably supported. It is characterized by always sliding the same distance in the opposite direction in the horizontal direction.
Thus, by synchronizing the movement of both sliders via the rack teeth and the pinion, the urging force of the urging member can be adjusted and the curtain plate can be gently extended. By adopting such a configuration, it is possible to prevent an accident in which the curtain plate suddenly jumps out and collides with an operator.

In the above gaming machine, one end of the connecting rod is pivotally attached to one curtain plate piece constituting the curtain plate, and a guide groove is formed on the other curtain plate piece and engaged with one end of the guide groove. A groove is continuously provided, and the other end of the coupling rod is loosely fitted in the guide groove, and when the curtain plate is bent and stretched, the tip of the coupling rod is slid along the guide groove, and the curtain plate The front end portion of the connecting rod is locked in the engagement groove when the projection extends forward, so that the curtain plate is held in a V shape.
In this way, when the curtain plate is refracted into a V shape and extends forward, the connecting rod is suspended, so that the strength in the V-shaped extension state is further increased.
According to the present invention, in the gaming machine, a release operation part for releasing the engagement between the distal end portion of the connecting rod and the engagement groove is provided on the curtain plate.
In this way, when the curtain plate is provided with a release operation part for releasing the engagement between the distal end portion of the connecting rod and the engagement groove, when the curtain plate is to be displaced from the extended state to the non-extended state, When releasing the engagement between the distal end of the connecting rod and the engaging groove, the operator displaces the finger between the pair of two divided curtain plates with the hand held between them. There is nothing wrong and safety can be ensured.

Rack teeth 35b are fixed horizontally to the horizontally extending portion 34b of the metal fitting 39b so that the tooth surfaces thereof face upward.

  The slider 25a is slidably supported by inserting the slide collar 27a into the rails 12a and 12a, and the slider 25b is slidable by inserting the slide collar 27b into the rails 12b and 12b. 4 and the pinion 37 shown in FIG. 4 is rotatably supported by a bearing body 38, and the bearing body 38 is fixed to the back plate 16 via a fixture 38a, whereby the pinion 37 is attached to the rack. The teeth 35a and the rack teeth 35b are arranged so as to mesh with each other. By engaging the pinion 37 with the rack teeth 35a and 35b in this way, the sliders 25a and 25b are synchronized and always slide the same distance in the opposite direction in the horizontal direction along the rails 12a, 12a, 12b and 12b. It becomes like this. FIG. 8 and FIG. 9 illustrate this arrangement situation and sliding situation. The slider 25a is urged inward by locking the other end of the biasing member 33a to the spring stop piece 9a, and the other end of the biasing member 33b is locked to the spring stop piece 9b. As a result, the slider 25b is also urged inward. That is, the sliders 25a and 25b are urged in the direction approaching each other by the urging members 33a and 33b.

  On the other hand, as shown in FIGS. 7, 10 and 11, the curtain plates 4a and 4b are formed of a pair of substantially rectangular plate-like curtain plate pieces 40a and 40b having a substantially U-shaped cross section divided into left and right. A hinge 41 is interposed between them so that they can be bent and stretched. The cover plates 42a and 42b are screwed to the front surfaces of the curtain plate pieces 40a and 40b. The hinge 41 is configured by inserting a pivot 43 into bearing holes formed in the hinge members 41a and 41b, and the hinge members 41a and 41b are screwed to the back surfaces of one end portions of the curtain plate pieces 40a and 40b, respectively. By doing so, the curtain plate pieces 40a and 40b can be bent and stretched. Note that a locking piece 45 is fixed to a portion of the back surface of the curtain plate piece 40a that approaches the hinge member 41a, and a tip end portion of the locking piece 45 bent in a hook shape is rearward from the back surface of the curtain plate piece 40a. It protrudes toward. Further, the locking portion 36 is screwed to the upper edge portion of the back surface of the curtain plate piece 40b.

  Further, the base end portion of the connecting rod 46 is pivotally attached to the upper edge portion of one curtain plate piece 40a by a pin 47, and the pin 48 is provided at the distal end portion of the connecting rod 46. Further, a guide groove 49 is formed in the upper edge portion of the other curtain plate piece 40b along the longitudinal direction of the curtain plate piece 40b, and the guide groove 49 is slightly refracted at one end of the guide groove 49 to be engaged. A groove 50 is provided continuously, and the pin 48 is slidably fitted in the guide groove 49, and the other end of a coiled spring 51 whose one end is locked to the pin 48 is engaged with the locking portion 36. The pin 48 is biased toward the engaging groove 50.

  Next, the configuration of the release operation portion 60 that allows the pin 48 positioned in the engagement groove 50 to be released from the engagement groove 50 and release the engagement will be described with reference to FIG. As shown in FIG. 7, the sliding piece 53 is slid right and left in the long hole 54 so that the knob 52 is exposed on the front surface of the surface plate 42b in the long hole 54 formed in the curtain plate piece 40b. The sliding piece 53 is urged in the direction of the arrow by a small coil-like spring 55 which is mounted so as to be movable and whose one end is locked to the back surface of the curtain plate piece 40b by a screw 55a. For this reason, when the slide piece 53 is slid against the elasticity of the spring 55 while pressing the knob 52 with a fingertip, the hook-shaped action portion 53a formed on the slide piece 53 is moved into the engagement groove. The pin 48 comes out of the engaging groove 50 by abutting and pressing the pin 48 in the pin 50. If the fingertip is released from the knob 52, the sliding piece 53 is returned to its original position by the elasticity of the spring 55.

  The curtain plate pieces 40a, 40b are inserted into the bearing portions formed at both ends of the curtain plate pieces 40a, 40b by inserting the support shafts 30a, 30b of the sliders 25a, 25b, respectively. It is pivotally supported so that it can rotate freely. Here, the winding springs 31a and 31b bias the curtain plate pieces 40a and 40b in the direction of projecting forward.

  Next, the configuration of the curtain plate locking mechanism 61 will be described with reference to FIGS. The curtain plate locking mechanism 61 engages and disengages the hook-like piece 45 fixed to the back surface of the curtain plate piece 40a with a lock fitting 59 provided on the back plate 16, and the lock fitting 59 advances and retracts inside. A lock piece 57 is provided so as to be freely movable, and the lock piece 57 is normally biased by a spring in the lock fitting so that a tip 58 formed in a wedge shape protrudes outwardly. A push button 56 serving as a lock release portion is provided on the back plate 16 so as to be exposed on the back surface of the back plate 16. Therefore, when the hook-shaped piece 45 abuts against the wedge-shaped slope of the tip 58, the tip 58 of the lock piece 57 is temporarily placed in the lock 59 against the elasticity of the spring in the lock 59. 14, and is restored by the elasticity of the spring and protrudes to engage with the hook-shaped piece 45 as shown in FIG. 14, and the curtain plates 4 a and 4 b are locked in the non-extended state (closed state). I try to do it. Further, when the push button 56 is pressed in this non-extending state, the tip end portion 58 retreats and the engagement with the hook-like piece 45 is released, so that the curtain plates 4a and 4b are moved forward. Can be overhanged. Therefore, both the sliders 25a and 25b approach each other by the urging force of the urging members 33a and 33b, and the curtain plates 4a and 4b are refracted into a V shape and project forward. It should be noted that the push button 56, which is the unlocking portion of the curtain lock mechanism 61, is provided so as not to be exposed on the front side of the gaming machine, and cannot be operated by the player.

  As described above, the gaming machine equipped with the self-standing device according to the present invention is operated by pressing the push button 56 from the back side of the gaming machine when temporarily placed in a standing state on the floor of the gaming hall, for example. As a result, the curtain plates 4a and 4b are refracted into a V shape at the same time and project forward as shown in FIG. For this reason, the gaming machine is in a stable standing state and is prevented from falling forward. When the curtain plates 4a and 4b are refracted in this way, the pin 48 at the tip of the connecting rod 46 is pulled by the spring 51 and slides in the guide groove 49 and enters the engagement groove 50 to be locked. Therefore, the connecting rod 46 is spanned between the curtain plate pieces 40a and 40b to form a plane triangular trust. For this reason, the strength is increased, and even a heavy gaming machine can be reliably prevented from falling. In addition, since the curtain plates 4a and 4b are urged by the urging members 33a and 33b, they are projected forward by one touch only by pressing the push button 56, and the operation becomes simple.

In order to return the curtain plates 4a and 4b projecting forward, the pin 48 is released from the engaging groove 50 and guided to the guide groove 4 by sliding the handle 52 in the direction of the guide groove 4 while pressing the knob 52 with a fingertip. Return to 49. After that, the pin 48 can slide freely in the guide groove 49. Therefore, when the curtain plates 4a and 4b are pushed by hand, the curtain plates 4a and 4b extend linearly as before, and the curtain It is stored between the plate end cover members 17a and 17b and is in a non-extending state (closed state). At this time, the hook-like piece 45 is engaged with the lock piece 57, so that this non-overhanging state is maintained. For this reason, in a state where the gaming machine is installed on the island base of the game hall, it is not possible for the player to know that such a self-supporting device exists when viewed from the front of the gaming machine, and there is no possibility that the aesthetic appearance will be impaired. The knob 52 remains exposed on the surface of the curtain plate 4b. However, even if the knob 52 is operated by the player, the sliding piece 53 only moves left and right. Absent.
In addition, since the common pinion 37 is engaged with the rack teeth 35a and 35b, and the sliders 25a and 25b always slide in the opposite direction in the horizontal direction, the biasing force of the biasing members 33a and 33b is reduced. The curtain plates 4a and 4b can be gently extended to prevent accidents such that the curtain plates 4a and 4b jump out suddenly and collide with an operator.

  As described above, the game machine equipped with the self-supporting apparatus according to the present invention has the curtain plate projecting forward, so that it can be provided in a conventional dead space without impairing the aesthetic appearance of the game machine. Further, since the curtain plate projects forward with one touch by operating from the back side of the gaming machine, the operation is simple and sufficient strength can be obtained in the extended state. For this reason, by providing this self-supporting device, even a heavy game machine can be reliably prevented from falling.
