Description

  The present invention relates to a ball game machine such as a pachinko machine installed and used in a game hall, and more particularly to a structure for mounting a transparent board on a front frame where a game board can be seen.

  A pachinko machine, which is a typical example of a ball and ball game machine, is a vertical rectangular machine frame installed on an island facility in a game arcade, a main body frame attached to the machine frame in a door-like manner, and a front surface of the main body frame. And a front frame attached in a door shape so as to be openable and closable. A game board is accommodated inside the main body frame. The game board has a game area defined by guide rails and the like, and this game area is provided with a variable display device, a start winning port, a general winning port, an attacker device, a game nail, a windmill, an out port, etc. ing. An opening facing the board surface of the game board is formed in the front frame, and this opening is covered with a transparent plate made of multilayer glass or the like. The transparent plate is detachably attached to the front frame. For example, if a defect such as a scratch or a crack occurs in the transparent plate, a new transparent plate is opened from the back side of the front frame in a state of being open to the main frame. Can be replaced.

  In the pachinko machine schematically configured as described above, a pair of support shafts are conventionally provided on one side surface of the transparent plate with a predetermined interval in the vertical direction, and the support shafts are provided on the back surface of the front frame. An attachment structure has been proposed in which the other side surface of the transparent plate is fixed to a single shaft hole by a pair of lock members disposed on the back surface of the front frame (for example, Patent Document 1). reference). In a pachinko machine that employs such a mounting structure, when the transparent plate is mounted with the front frame opened, when the two support shafts of the transparent plate are inserted into the shaft holes of the corresponding support pieces of the front frame, Since the side surface is held by the front frame via the support shaft and the hinge part of the support piece, the transparent plate is rotated in the shape of a door around the support shaft in this state to close the opening, and then the lock member is rotated. By operating and fixing the other side of the transparent plate to the front frame, the transparent plate can be easily attached to the front frame.

  By the way, when adopting the mounting structure in which the support shaft provided on one side of the transparent plate is hinged to the support piece of the front frame, when mounting the transparent plate with the front frame open, After the hinge is joined to the frame, the transparent plate may turn inadvertently with the hinge portion as a fulcrum and hit a game board or the like. Therefore, in the conventional pachinko machine described above, the stopper is held in a holding portion provided on the back surface of the front frame so as to be movable up and down, and the stopper is moved downward after inserting the support shaft of the transparent plate into the shaft hole of the support piece. However, the rotation range of the transparent plate is restricted by a stopper. However, there is a problem that not only the cost is increased by the holding portion and the stopper, but also the width of the opening cannot be increased due to the presence of the holding portion and the stopper. It was.

  As an alternative to the hinge-type mounting structure described above, the lower end of the transparent plate is engaged with a hook provided on the back surface of the front frame, and the transparent plate is rotated upward with this hook as a fulcrum. It is conceivable that the upper end of the transparent plate is fixed to the front frame by turning the lock member disposed on the upper back of the front frame after the cover is closed. According to such a mounting structure, the space for arranging the hinge portion and the lock member on both the left and right sides of the opening is not required, so that the width dimension of the opening can be increased as the game area and the transparent plate increase in size. Although it becomes possible, since it is necessary to support the transparent plate in the middle of attachment so that it does not fall forward until it is fixed by the lock member, a new problem arises that the physical burden on the operator increases.

  The present invention has been made in view of such a state of the art, and an object thereof is to provide a ball game machine in which a transparent plate can be easily and safely attached to a front frame.

In order to achieve the above object, the present invention provides a game board having a game area in which a game ball flows down, a main body frame to which the game board is attached, and one side portion pivotally attached to the front surface of the main body frame. A front frame that can be freely opened and closed, and a transparent plate that is detachably attached to the back surface of the front frame so as to cover an opening provided in the front frame, and the game is passed through the transparent plate. in a ball-shooting game machine which board has become visible, the transparent plate, and a pair of temporary locking pieces having a through hole protrudes outward from the both sides, both sides a position above these temporary joint members A pair of fixed pieces projecting outward from the portion, a hook portion that can lock the lower edge portion of the transparent plate on the back surface of the front frame, and a position above the hook portion. a pair of detent projection portions having an inclined surface and the retaining groove Te, the detent projection portions A positioning projection which can fit into the through hole located in the vicinity, and a pair of lock members are provided capable of holding the fixing piece located above said detent projection portions, the transparent plate by rotating to the back side of the front frame to pivot said hook portion, said temporary stopping piece is slid obliquely upward along the inclined surface down to the holding groove write Mutotomoni, the positioning projection The transparent plate is positioned in the left-right direction with respect to the front frame by fitting the through-hole to the front frame , and then the lock member is manually operated to be engaged with the fixed piece, whereby the transparent plate is moved to the front surface. Fixed to the frame.

In the ball game machine configured as described above, when the front frame is opened and the transparent plate is attached, when the lower edge of the transparent plate is engaged with the hook portion of the front frame and pushed forward, the transparent plate It turns so that it becomes a standing posture with the lower hook part as a fulcrum, and the temporary fixing piece of the transparent plate contacts the inclined surface of the temporary fixing protrusion provided on the front frame in the middle of the rotation. By pressing, the temporary fixing piece slides obliquely upward along the inclined surface of the temporary fixing protrusion and automatically falls into the holding groove. At this point, the transparent plate is temporarily fixed to the back surface of the front frame. It won't fall to the near side. Further, in this temporarily fixed state, the transparent plate is positioned in the left-right direction with respect to the front frame by fitting the through hole of the temporary fixing piece to the positioning protrusion in the vicinity of the temporary fixing protrusion. Therefore, the transparent plate can be permanently fixed to the front frame by manually operating the pair of lock members in this temporarily fixed state and locking them to the corresponding fixing pieces. Therefore, the transparent plate can be easily and safely attached to the front frame without any special support.

  In the above configuration, the finger hooking portion is integrally formed on at least the upper edge side of the temporary fixing piece, and when the finger hooking portion protrudes toward the rear of the transparent plate, the work is performed when the transparent plate is removed from the front frame. By removing the temporary fixing piece from the holding groove of the temporary fixing projection and releasing the temporary fixing state of the transparent plate, the transparent plate can be easily and safely removed from the front frame. Can do.

The bullet ball game machine of the present invention is provided with a temporary fastening piece projecting outward from its side on a transparent plate, and with a hooking portion, a temporary fastening projection and a locking member on the back surface of the front frame. When attaching the transparent plate with the front frame opened, if the lower edge of the transparent plate is engaged with the hook and pushed forward to rotate, the temporary fixing piece will come to the inclined surface of the temporary fixing protrusion. The guide plate falls into the holding groove while being guided, and is in a temporarily fixed state, and the through hole is fitted to the positioning protrusion and positioned in the left-right direction. The main plate can be permanently fixed to the front frame, and the transparent plate can be easily and safely attached to the front frame without having to manually support the transparent plate before the main fixing.

Has been.

  As shown in FIG. 8, the transparent plate 5 is composed of two pieces of glass 21 laminated at a predetermined interval, and a frame body 22 integrated on the outer edges of both glasses 21. The glass 21 and the frame 22 are handled as one unit product. Engagement protrusions 22a are formed on the left and right sides of the lower end of the frame 22, and the lower edge of these engagement protrusions 22a is rounded. Temporary fastening pieces 22b are formed on both left and right sides above the middle of the frame 22, and a fixed piece 22d having a locking hole 22c is provided in the left-right direction above the temporary fastening pieces 22b. They are formed one by one at intervals. As shown in FIG. 9, the temporary fixing piece 22b on the left side protrudes outward from the frame body 22, and a through-hole 22e extending in the vertical direction is formed in the central portion. As will be described later, when the transparent plate 5 is attached to the front frame 4, the through holes 22 e enter the corresponding positioning protrusions 18 of the front frame 4. Further, a finger hook portion 22f that protrudes like a bowl is formed on the upper edge side of the temporary fixing piece 22b, and the lower end surface of the temporary fixing piece 22b is tapered. The temporary fixing piece 22b on the right side is configured similarly. However, the width dimension of the through hole 22e with respect to the positioning projection 18 of the front frame 4 is slightly different on the left and right, and in the case of this embodiment, the left through hole 22e is set wider than the corresponding positioning projection 18, The right through hole 22e is set to have the same width as the corresponding positioning protrusion 18.

  Next, a procedure for attaching the thus configured transparent plate 5 to the front frame 4 will be described with reference to FIGS.

  First, the locking device 15 is unlocked and the front frame 4 is greatly opened with respect to the main body frame 2 (see FIG. 2), and a pair of hooks formed at the lower end of the opening 4a as shown in FIGS. 16 is engaged with a corresponding engagement protrusion 22a of the transparent plate 5. In this state, when the transparent plate 5 is pushed forward from the back side of the front frame 4 so as to approach the opening 4a, the transparent plate 5 pushes the lower edge portion of the engaging protrusion 22a (contact portion with the hook portion 16). As a fulcrum, it rotates in the direction of arrow P in FIG. 11, and the lower end of the temporary fixing piece 22 b formed on the transparent plate 5 contacts the inclined surface 17 a of the temporary fixing protrusion 17 formed on the front frame 4 during the rotation. When the transparent plate 5 is further pushed forward, as shown in FIGS. 13 to 15, the temporary fixing piece 22b slides obliquely upward along the inclined surface 17a of the temporary fixing protrusion 17, and then automatically enters the holding groove 17b. At this point, the transparent plate 5 is temporarily attached to the back surface of the front frame 4 and does not fall forward. As the temporary fixing piece 22b slides, the engaging protrusion 22a is lifted from the bottom surface of the recess 16a of the hooking portion 16, but the engaging protrusion 22a is not dropped from the hooking portion 16 by the standing portion 16b. ing.

  Further, since the right through hole 22e of the transparent plate 5 is fitted into the right positioning protrusion 18 in the temporarily fixed state, the transparent plate 5 is positioned in the left and right direction with respect to the front frame 4 by the positioning protrusion 18 and the through hole 22e. Is done. At this time, the left through hole 22e of the transparent plate 5 also enters the left positioning protrusion 18, but as described above, the through hole 22e is set wider than the positioning protrusion 18, and therefore the front frame 4 The positioning protrusion 18 and the through-hole 22e on the left side as viewed from the back side of the lens are not involved in the positioning function. Thereafter, as shown in FIG. 17, the left locking member 19 is rotated counterclockwise by about 90 degrees, and the right locking member 19 is rotated clockwise by about 90 degrees. Stopper protrusions (not shown) of both lock members 19 are fitted into the locking holes 22c of the corresponding fixing pieces 22d of the transparent plate 5. As a result, the vertical movement of the transparent plate 5 is blocked by the lock member 19, and the transparent plate 5 is permanently fixed to the front frame 4.

  As described above, when the front frame 4 is opened and the transparent plate 5 is attached, the engagement protrusion 22a of the transparent plate 5 is engaged with the hook 16 of the front frame 4 and pushed forward to rotate. Since the stopper piece 22b falls into the holding groove 17b from the inclined surface 17a of the temporary fixing projection 17 and enters the temporary fixing state, the transparent plate 5 can be permanently fixed to the front frame 4 by the lock member 19 in this temporary fixing state. The transparent plate 5 can be easily and safely attached to the front frame 4 without bothering to support the transparent plate 5 before being fixed by the operator's hand.

  When removing the transparent plate 5 from the front frame 4, the lock member 19 is rotated in a direction away from the fixing piece 22 d to return the transparent plate 5 to the temporarily fixed state, and then the operator's fingers are hung on the left and right fingers. When the transparent plate 5 is lifted by being hooked on the portion 22f and rotated to the near side, both the temporary fixing pieces 22b are released from the holding grooves 17b of the corresponding temporary fixing projections 17 so that the temporarily fixed state can be released. Can be removed from the front frame 4 easily and safely.

  In the above embodiment, the transparent plate 5 is positioned in the left-right direction with respect to the front frame 4 by using the positioning protrusion 18 and the through hole 22e formed on the right side when viewed from the back side of the front frame 4. However, it is also possible to provide such a positioning function to the positioning protrusion 18 and the through hole 22e formed on the left side.

  In the above embodiment, the operation handle 15 and the like are integrally provided below the front frame 4 to which the transparent plate 5 is mounted, and the game board 6 and the installation portion 2a are included by the front frame 4 having such an integrated structure. The ball game machine that covers the front surface of the main body frame 2 has been described. The upper front frame (glass door) that covers the game board 6 side and the lower front frame (front board) that covers the installation portion 2a side are described above and below. The present invention is also applicable to a ball game machine in which a split type front frame divided into two parts is used and the transparent plate 5 is detachably attached to the upper front frame.
