Description

  The present invention relates to a gaming machine to which an opening / closing member is attached so as to be openable / closable with one side of a frame-shaped member as a pivot.

  In general, a pachinko machine has a rectangular outer frame that serves as an installation base when installed in a pachinko hall, and a rectangular shape that is attached so that the front side of the outer frame can be opened and closed with one side of the outer frame as a pivot. A middle frame and a front frame attached to the front side of the middle frame so as to be openable and closable with one side of the middle frame as a rotation fulcrum. A game board on which the game ball rolls and a display device that produces and displays a big win lottery are attached to the middle frame, and a glass plate that covers the game board so as to be visible is attached to the front frame.

  When troubles such as ball clogging occur in the game board, pachinko hall employees open the front frame to remove the trouble. At this time, the front frame is likely to be in a state where the tip side is lowered from the rotation fulcrum side due to the weight of the glass plate and other accessories, and in particular, when the opening / closing operation is repeated over a long period of time, the play of the rotation fulcrum gradually increases. Therefore, the drooping of the front frame increases. In this case, in order to prevent the lower end of the front frame from interfering with the edge of the middle frame when the front frame is closed, it is necessary to lift the front frame.

  The middle frame also has a considerable weight due to the weight of the game board, display device, various control boards, etc., so that when the middle frame is opened to replace or check the game board, the tip side of the middle frame is a pivot point. There is a tendency to be lower than the side. Therefore, in order to prevent the lower end of the middle frame from interfering with the edge of the outer frame when the middle frame is closed, the middle frame needs to be lifted.

  Therefore, a pachinko machine described in Patent Document 1 has been proposed in order to smoothly open and close the inner frame. In this pachinko machine, on the upper surface of the lower frame of the outer frame, a portion facing the lower surface of the middle frame is provided with a guide surface inclined in a direction gradually increasing from the front side toward the rear side. The middle frame that rotates in the closing direction is guided upward. Therefore, it is possible to prevent the lower end of the middle frame from interfering with the edge of the outer frame even when the middle frame is not lifted up and closed.

  Further, in this pachinko machine, a folded portion is provided on the lower frame of the outer frame so as to face the back side of the middle frame. The folded portion is formed in a U-shaped cross section that opens toward the joint between the outer frame and the middle frame, and the fraudulent act of inserting a device such as a piano wire or celluloid board from the joint between the outer frame and the middle frame ( When the so-called piano wire goto or sergoto) is performed, the tip of the instrument is received to prevent the instrument from entering the pachinko machine.

  By the way, the lower frame of the outer frame is provided with a folded portion that faces the back side of the middle frame, but the upper surface of the lower frame of the outer frame faces the lower surface of the middle frame from the front side to the rear side. Only the guide surface inclined in the direction of increasing toward the side is provided, and it does not have a structure that prevents the intrusion of instruments such as piano wires and celluloid plates. If this inventor can also introduce the structure which prevents the penetration | invasion of instruments, such as a piano wire and a celluloid board, about this guide surface part, it can prevent a piano wire goto, a selgot etc. more effectively. We focused on the points. The same can be said for gaming machines other than pachinko machines (slot machines, etc.).

  An object of the present invention is to provide a gaming machine having a function of preventing an instrument such as a piano wire or a celluloid board from entering an opposing portion where the lower surface of the opening / closing member and the frame-shaped member are vertically opposed to each other.

  In order to achieve the above object, the present invention comprises a frame-shaped member and an opening / closing member attached to the front side of the frame-shaped member so that the front side of the frame-shaped member can be opened and closed with one side of the frame-shaped member as a pivot. In a gaming machine provided with a facing portion in which the lower surface of the opening and closing member and the frame-shaped member face each other in the closed state, a plurality of chevron ribs extending in the left-right direction are formed on one of the facing portions facing vertically. Provided side by side in the front-rear direction, and on the other side, a plurality of rib engaging grooves that are engaged with the chevron ribs in a state where the opening / closing member is closed are provided side by side in the front-rear direction.

  As described above, in the present invention, the angle rib is provided on one of the vertically opposed portions, and the rib engagement groove is provided on the other, so that the engagement between the rib engagement groove and the angle rib is performed. Therefore, it is possible to prevent the intrusion of instruments such as a piano wire and a celluloid board. Further, when the opening / closing member is opened / closed, both members move relative to each other along the inclination of the angle rib, so that the angle rib and the rib engagement groove are smoothly engaged and disengaged.

  The present invention is applied to an outer frame that becomes an installation base when installed in a pachinko hall, and an opening / closing structure of a middle frame that is attached so that the front side of the outer frame can be opened and closed with one side of the outer frame as a pivotal support. Of course, it can be opened and closed with a middle frame that can be opened and closed with respect to the outer frame, and a front frame that can be opened and closed with one side of the middle frame as a pivot. Can also be applied.

  According to the gaming machine of the present invention, the chevron rib provided on one of the upper and lower portions of the lower surface of the opening / closing member and the lower frame of the frame-like member engages with the rib engaging groove provided on the other, thereby Further, it is possible to effectively prevent piano wire goto, selgoto, and the like since intrusions of instruments such as celluloid plates are prevented.

  When the front frame 6 is closed, the lower frame of the middle frame 4 is opposed to the lower surface of the front frame 6 in the vertical direction, and the frame is elongated to the left and right along the lower edge of the front opening of the middle frame 4. The front frame 6 with respect to the joint portion 21, the first guide member 22 disposed on the side close to the pivot point of the front frame 6 with respect to the frame fitting portion 21 (left side in the figure), and the frame fitting portion 21. And a second guide member 23 disposed on the side far from the rotation fulcrum (right side in the figure).

  The frame fitting portion 21 is a portion that overlaps with the lower surface of the front frame 6 in a state where the front frame 6 is closed and becomes a joint of the frames. A folded portion 24 is provided at the rear end of the frame fitting portion 21. The folded portion 24 prevents the instrument from entering the pachinko machine 1 when an instrument such as a piano wire or celluloid board is inserted from the joint of the front frame 6 and the middle frame 4.

  On the upper surface of the first guide member 22, an inclined surface 25 that is inclined in a direction gradually increasing from the front side toward the rear side is formed. When the front frame 6 rotates in the closing direction, the inclined surface 25 guides the front frame 6 upward by the inclination.

  As shown in FIG. 5, a first guided portion 26 corresponding to the first guide member 22 is provided in a facing portion of the lower surface of the front frame 6 facing the middle frame 4 in the vertical direction. The first guided portion 26 is a portion that is guided in contact with the inclined surface 25 of the first guide member 22 when the front frame 6 rotates in the closing direction. The first guided portion 26 is formed with a plurality of protrusions 27 extending in the front-rear direction in order to keep the sliding resistance with the inclined surface 25 small.

  As shown in FIG. 6, on the upper surface of the second guide member 23, a plurality of angle ribs 28 extending in the left-right direction are provided side by side in the front-rear direction. As shown in FIG. 7, each chevron rib 28 has a cross-sectional chevron shape with a ridge line extending in the left-right direction as a top, and a front guide surface 29 and a rear guide surface 30 are formed with the top as a boundary. Here, the front guide surface 29 is inclined in a direction increasing from the front side toward the rear side, and the rear guide surface 30 is inclined in a direction decreasing from the front side toward the rear side.

  As shown in FIG. 4, the second guide member 23 is provided at the upper end of the side wall of the lower plate 15 so as to be positioned in front of the front edge of the frame fitting portion 21, and when the front frame 6 is closed, The front frame 6 starts to overlap the second guide member 23 at an earlier timing than the lower surface of the frame 6 overlaps the frame fitting portion 21 of the middle frame 4 in the vertical direction.

  As shown in FIG. 5, a second guided portion 31 corresponding to the second guide member 23 is provided on the lower portion of the front frame 6 facing the middle frame 4 in the vertical direction. The second guided portion 31 is a portion facing the upper side of the second guide member 23 when the front frame 6 is closed, and the lower surface of the second guided portion 31 is left and right with the front frame 6 closed. A plurality of rib engaging grooves 32 extending in the direction are provided side by side in the front-rear direction.

  As shown in FIG. 7, the rib engaging groove 32 has a square groove shape with a square cross section having inner surfaces facing front and rear. Each rib engaging groove 32 is formed at a position that vertically matches each chevron rib 28. When the front frame 6 is closed, each chevron rib 28 and each rib engaging groove 32 are engaged to each other. The top of the chevron rib 28 enters the rib engaging groove 32. A folded portion 33 is provided at the rear end of the second guide member 23 so as to face the back side of the front frame 6. The front frame 6 is accommodated in the folded portion 33 with the front frame 6 closed. A protrusion 34 is provided.

  In the pachinko machine 1 configured as described above, when a trouble such as a ball clogging occurs in the game board 8, an employee of the pachinko hall opens the front frame 6 as shown in FIG. 4 in order to remove the trouble. At this time, the front frame 6 tends to be in a state in which the tip side is lowered from the rotation fulcrum side due to the weight of the glass plate 11 and other accessories, and in particular, when the opening / closing operation is repeated for a long time, the play of the rotation fulcrum gradually increases. Since it becomes large, the drooping of the front frame 6 becomes large.

  Therefore, when the front frame 6 is closed, the lower end of the front frame 6 may interfere with the edge of the middle frame 4 (for example, the edge of the upper end of the side wall of the lower plate 15). However, in the pachinko machine 1 of the present embodiment, When the front frame 6 is rotated in the closing direction, as shown in FIGS. 6 and 8A, the rear ends of the second guided portions 31 are arranged in the front-rear direction of the second guide member 23. The second guided portion 31 is brought into contact with the front guide surface 29 of the chevron rib 28 located on the foremost side of the chevron ribs 28, and then along the inclination of the front guide surface 29 as shown in FIG. Is guided upward, the lower end of the front frame 6 does not interfere with the edge of the middle frame 4 even if the front frame 6 is not lifted.

  When the front frame 6 is completely closed, as shown in FIG. 7, each chevron rib 28 is engaged with each rib engaging groove 32. In this state, even if an instrument such as a piano wire or a celluloid plate is inserted into the joint between the second guided portion 31 and the second guide member 23 from the front, the pachinko is engaged by the engagement of the chevron rib 28 and the rib engaging groove 32. Intrusion of instruments into the machine 1 is prevented. In particular, as shown in the figure, when the rib engaging groove 32 is formed into a square groove shape, the tip of the instrument is guided to the corner of the rib engaging groove 32 along the front guide surface 29 of the chevron rib 28, and beyond that, Since it can no longer be advanced, the effect of preventing the intrusion of instruments such as piano wires and celluloid plates is high.

  Even when an instrument such as a piano wire or a celluloid plate passes through the engagement portion between the rearmost chevron rib 28 and the rib engagement groove 32, the folded portion 33 of the second guide member 23 and the front frame 6 The protrusion 34 prevents the instrument from entering.

  When the front frame 6 is rotated from the closed state in the opening direction, the rear edge of each rib engaging groove 32 contacts the rear guide surface 30 of the chevron rib 28 and the rear guide surface 30 is inclined. , The front frame 6 is guided upward, and the engagement between the chevron rib 28 and the rib engaging groove 32 is released.

  In the pachinko machine 1 of the present embodiment, the front guide surface 29 of the chevron rib 28 provided on the second guide member 23 of the middle frame 4 guides the front frame 6 rotating in the closing direction upward, and the chevron The ribs 28 engage with the rib engaging grooves 32 provided in the second guided portion 31 of the front frame 6 to prevent the intrusion of instruments such as piano wires and celluloid plates. That is, the chevron ribs 28 have both a function of guiding the front frame 6 that rotates in the closing direction upward and a function of preventing the intrusion of instruments such as piano wires and celluloid plates. Therefore, it is possible to more effectively prevent piano wire goto, selgoto, and the like than when the intrusion of instruments such as a piano wire and celluloid plate is prevented only by the folded portion 33.

  Further, when the front frame 6 is opened and closed, the front frame 6 moves along the inclination of the front guide surface 29 and the rear guide surface 30 of the chevron rib 28, so that the engagement between the chevron rib 28 and the rib engagement groove 32 is performed. The engagement and disengagement are performed smoothly.

  As shown in FIG. 9, a groove 35 may be further provided between the adjacent rib engaging grooves 32 and the rib engaging grooves 32. In this case, even if an instrument such as a piano wire or a celluloid plate passes through the engaging portion between the chevron rib 28 and the rib engaging groove 32, the instrument is hardly caught by entering the edge of the groove 35.

  As shown in FIGS. 10 and 11, a plurality of protrusions 36 extending in the front-rear direction may be formed between the adjacent rib engagement grooves 32 and the rib engagement grooves 32 at intervals in the left-right direction. If it does in this way, the contact area between the 2nd to-be-guided part 31 and the chevron rib 28 can be reduced, and the sliding resistance can be restrained small.

  In the present embodiment, the angle ribs 28 are provided on the lower frame of the middle frame 4 and the rib engagement grooves 32 are provided on the lower surface of the front frame 6. However, the correspondence between the angle ribs 28 and the rib engagement grooves 32 is reversed. The rib engaging groove 32 may be provided in the lower frame of the middle frame 4, and the chevron rib 28 may be provided in the lower surface of the front frame 6. That is, a chevron rib 28 is provided in a portion of the lower surface of the front frame 6 facing the middle frame 4 in the vertical direction, and a rib engaging groove 32 is formed in a portion of the lower frame of the middle frame 4 facing the lower surface of the front frame 6 in the vertical direction. May be provided. Also in this case, when the front frame 6 is opened and closed, the front frame 6 moves along the inclination of the front guide surface 29 and the rear guide surface 30 of the chevron rib 28, so that the chevron rib 28 and the rib engaging groove 32 are moved. Are smoothly engaged and disengaged. And in the state which closed the front frame 6, the penetration | invasion of instruments, such as a piano wire and a celluloid board, can be prevented by engagement of the chevron rib 28 and the rib engaging groove 32.
