[0001]
TECHNICAL FIELD OF THE INVENTION
The present invention includes a glass door which is attached to the front side of a frame member holding the game board so as to be openable and closable and allows the game board to be seen through, and the glass door is closed so as to cover the front face of the game board. The present invention relates to a gaming machine used for a game, and more particularly, to a glass holding mechanism of a gaming machine that is useful when attaching and detaching a glass plate to and from such a glass door.
[0002]
[Prior art]
As a gaming machine provided with the above-mentioned glass door, there is a vertical gaming machine such as a pachinko machine, an arrangement ball machine, and a sparrow ball gaming machine. For example, in a pachinko machine exemplified as a typical example of this type of gaming machine, a gaming board in which a gaming area is formed with a predetermined gauge setting in a front deep portion of a front frame serving as an open / close mounting frame is set and held. A glass door is provided on the front side to protect the game area through see-through.
[0003]
The glass door has a window opening in the center and is integrally molded in an outer shape, and two front and rear panels attached to the back side of the door frame via glass holding means so as to close the window. And a hinge plate disposed on the left side edge of the door frame and the front frame, which is supported to be openable and closable, and a locking device disposed on the right side edge of each other. It is attached so that it can be closed and held by utilizing. As a glass holding means, a metal glass frame screw-fixed on the back side of a door frame so as to surround a window has been widely used. Guide rail-shaped support grooves for supporting the outer peripheral edge of the glass plate are formed in two rows on the left and right sides of the glass frame, and the glass plate is inserted along each support groove from above the glass frame. It is configured to hold the glass plate with.
[0004]
The pachinko machine is removed from the glass door when shipping the pachinko machine and packed separately to prevent damage due to rough handling and vibration during the transportation of the pachinko machine, and the pachinko machine is fixedly installed in the game facility After that, the door frame is opened and inserted one by one into the glass frame.
[0005]
[Problems to be solved by the invention]
However, in the conventional glass holding mechanism as described above, when the glass plate is mounted, the glass plate is already set upright and the glass plate is set upright to the upper end position of the glass frame at a high position. , The lower ends of the right and left side edges of the glass plate must be aligned with and engaged with the support grooves, and further inserted vertically downward along the support grooves. Also, when removing the glass plate, it is necessary to lift the glass plate upward and pull it out while maintaining the vertical posture to a high position. Particularly, since the glass plate located on the front side of the glass door is disposed so as to be in close contact with the back surface of the glass door, it is not easy to insert and remove the glass plate. For this reason, there has been a problem that the work of attaching and detaching the glass plate is complicated and heavy labor, and there is also a problem that the glass plate may be damaged in the course of this work.
[0006]
One of the attempts to solve such a problem is a technique described in Japanese Patent Application Laid-Open No. 10-80555. This means that the glass frame supporting the outer peripheral edge of the glass plate is arranged to be tiltable back and forth with respect to the door frame, the door frame is opened, and the upper portion of the glass frame is tilted rearward of the window, and the glass is The plate is inserted obliquely downward from above the glass frame to facilitate the work of mounting the glass plate. However, in the technique described in the above-mentioned publication, although the insertion direction of the glass plate changes obliquely by tilting the glass frame, the height position of the upper end of the glass frame, that is, the height position of the glass groove to be inserted is tilted. There is no significant difference in the operation of lifting the glass plate to the upper end of the glass frame at a high position, supporting it and engaging it with the support groove, making it easy to attach and detach and prevent breakage of the glass plate. However, there was a problem that it was not enough. The glass frame that tilts back and forth is formed by connecting three frame rods with glass grooves formed at right angles to the frame, and functions as a reinforcing plate for the door frame when the glass frame is closed and fixed to the door frame. When the glass frame is unlocked and tilted backward and the glass plate is to be mounted in such a state, the door frame is bent and deformed by the external force applied at this time, and the glass frame swings. However, there is a problem that the work of mounting the glass plate cannot be performed smoothly.
[0007]
The present invention has been made in view of the above problems and problems, and facilitates the work of attaching and detaching a glass plate, which is complicated and heavy labor, to improve workability, and to prevent breakage of the glass plate during the work process. It is an object of the present invention to provide a glass holding mechanism capable of reducing the temperature.
[0008]

It is a glass holding mechanism of a gaming machine for playing a game. In addition, the glass holding means of the present invention includes an upper protection member (for example, the upper protection frame 55 in the embodiment) that engages with the upper peripheral edge of the glass plate to protect the upper portion of the glass plate, and a lower peripheral edge of the glass plate. A lower protection member (for example, the lower protection frame 53 in the embodiment) that protects the lower portion of the glass plate in combination, and a tilting support mechanism (for example, provided at a lower portion of the door frame and supporting the lower protection member to be able to tilt back and forth) (for example, , A tilting support mechanism including a shaft pin 52b, a shaft engaging portion 53b, a tilt regulating hole 52c, a knurled screw 61, and the like in the embodiment, and the tilt support mechanism engages and holds the lower protection member. It can be shifted between a standing angle position in which the glass plate thus set is raised vertically upward along the back of the window and a detachable angle position in which the upper portion of the glass plate is inclined rearward of the window. Glass holding mechanism is configured.
[0009]
In the glass holding mechanism having such a configuration, the protective member for protecting the outer peripheral edge of the glass plate is vertically divided so as to be able to engage with the glass plate, and the lower protective member is tilted by the tilting mechanism to lower the lower part of the door frame. , And is configured to be capable of displacing the glass plate engaged and held by the lower protection member between a standing angle position and a detachable angle position. Therefore, even if the upper side of the glass door is located at a higher position as in the case where the glass plate is mounted on the glass door of the gaming machine already fixedly installed, the lower protection member supported by the lower part of the door frame is provided. By inserting or removing the glass plate by tilting it to the attachment / detachment angle position, the glass plate can be attached / detached at a low working position, making it easy and safe even for short workers and unskilled workers. The work of attaching and detaching the glass plate can be performed.

FIG. 6 is an explanatory view showing each part of the holding mechanism 50 as a partially enlarged view, and FIG. 6 is a plan sectional view showing a state in which the glass door 5 is closed.
[0019]
In describing the door opening / holding mechanism 40, a schematic configuration of the glass door 5 will be described first. The glass door 5 has a window 51a that opens front and rear, and is a resin door that is integrally molded into an outer rectangular frame shape. A frame 51, and a fixed support frame 52 made of a thin sheet metal and fixed to the rear side of the door frame 51 by screws around the window 51a (a lower frame portion 52U, a left frame portion 52L, and a right frame portion 52R). And two front and rear glass plates 54, 54 whose outer peripheral edges are held by upper and lower protection frames 55, 53 and which can be tilted back and forth by a glass holding mechanism described in detail later. Hinge mechanisms 7a and 7b provided on the front left side of the front frame 2 support the front frame 2 to be freely opened, closed, and attached and detached.
[0020]
The first opening / holding mechanism 40A of the door opening / holding mechanism 40 is mainly composed of a locking metal 41 that is supported by the fixed support frame 52 (52U) below the glass door so as to be able to turn horizontally. The locking fitting 41 is formed in a strip-shaped elongated holding rod portion 41a, a turning shaft portion 41b formed on the base end side of the holding rod portion 41a, and a drilling hole formed on the distal end side of the holding rod portion 41a. For example, a cold-rolled steel plate having a predetermined thickness is punched and formed by press working or the like, and a swiveling shaft portion 41b including a male screw portion and a thin disk-shaped seat portion is crimped and pressed. A required surface treatment such as a chromate treatment is performed to form the illustrated embodiment.
[0021]
In the lower frame portion 52U of the fixed support frame 52, at the intermediate position between the front and rear glass plates 54, 54 (more specifically, at the intermediate position between the front and rear glass grooves in the lower protection frame 53), the external thread portion of the revolving shaft portion 41b is positioned. Also, a shaft hole having a somewhat larger inner diameter is formed (see FIG. 5), and a male screw portion is inserted from below the support surface of the lower frame portion 52U, and the nut 42 is screwed from the support surface side. Thereby, the locking fitting 41 is attached to the lower part of the glass door 5 so as to be able to turn horizontally. Locking hooks 52f projecting rearward are formed at the left and right central portions of the lower frame portion 52U by cut-and-raising forming, and when the distal end side of the locking metal member 41 is horizontally turned along the lower frame portion 52U. Furthermore, the lower surface of the support rod portion 41a is supported, and the lower end of the lower frame portion 52U is configured to be able to lock and hold the lock fitting 41 (see FIGS. 3 and 6). As a result, the locking fitting 41 is always locked by the locking hook 52f, and is compactly stored and held under the lower frame portion 52U.
[0022]
In addition, a wire, a thin metal plate, or the like is inserted from a passage gutter 15 provided in the upper ball tray 6 above the passage outlet 14 so as to prevent unauthorized operations from being performed. An eave portion 17 protruding forward is formed so as to cover one side, and the front portion of the eave portion 17 is covered by the lower frame portion 52U when the glass door 5 is closed. Behind the eaves 17, pin-shaped locking projections 17a and 17b are formed so as to be detachable from the locking hole 41c of the locking metal.
[0023]
Here, the length of the holding rod portion 41a of the locking metal fitting 41 and the position where the two locking projections 17a and 17b are formed are based on the opening angle of the glass door 5 to be opened and held with respect to the front frame 2. For example, as shown by a solid line and a two-dot chain line in FIG. 4, when the locking hole 41c is engaged with the locking projection 17a on the front right side and stretched, the opening angle of the glass door 5 is set. Is set to 90 degrees, and the opening angle of the glass door 5 is set to 110 degrees (an angle close to the maximum opening angle on the mechanism) when the glass door 5 is stretched by engaging with the locking projection 17b on the front left side. . This allows the glass door to be locked and held at an opening angle of 90 degrees when sequentially attaching glass plates to an adjacent pachinko machine or performing maintenance work, and performs nail adjustment for each pachinko machine. In some cases, such as holding at an opening angle of 110 degrees, it is possible to hold at two stages of opening angles according to the work purpose. The opening angle may be set to another angle, or three or more opening angles may be provided so as to be locked and held at multiple angular positions.
[0024]
The second opening / holding mechanism 40 </ b> B of the door opening / holding mechanism 40 mainly includes a fixing bracket 46 supported on the back surface of the glass door 5 so as to be vertically swingable in a vertical plane. The fixing bracket 46 has a belt-shaped arm portion 46a, a cylindrical swing shaft portion 46b extending vertically from the plate surface to the base end side of the arm portion 46a and crimped and crimped, and a distal end side of the arm portion 46a swings. A fixing piece 46c formed by being bent at a right angle in a direction opposite to the moving shaft 46b, a U-shaped screw engaging groove 46d formed by opening the fixing piece downward, and the like; It is configured by the same processing means using the same metal material as 41.
[0025]
On the back side of the door frame 51 to which the fixing bracket 46 is attached, a boss 51b protruding rearward from the face material on the window side is integrally formed, and a screw receiving hole for receiving a screw is formed in the center of the rear end side. Have been. The protruding height of the boss 51b is formed at the same height as the supporting boss or the rib supporting the fixed support frame 52, while the left end portion 52L of the fixed support frame 52 exposes the rear end face of the boss 51b and swings. A support hole 52h that rotatably fits and supports the front end of the moving shaft 46b is formed.
[0026]
In the closed position of the glass door 5, a fixed support portion 2c is formed on the front end surface of the front frame 2 located behind the door frame 51 to abut the fixing piece portion 46c of the fixing metal. A screw receiving hole for receiving the screw 48 is formed (see FIG. 5).
[0027]
The fixing bracket 46 fits the front end portion of the swing shaft portion 46b into a support hole 52h formed in the left frame portion 52L to abut the boss 51b, and screws the screw 47 from behind the swing shaft portion 46b. By being inserted and screwed into the screw receiving hole of the boss 51b, it is swingably supported on the rear surface of the glass door 5 in a vertical plane.
[0028]
The fixing bracket 46 shown in this embodiment is configured so that the glass door 5 can be locked and held or fixedly held at an opening angle of 90 degrees, and the length of the arm portion 46a and the formation position of the fixed support portion 2c are determined by the glass door. When the fixing arm 5 is opened at an opening angle of 90 degrees and the arm 46a of the fixing bracket is swung from above so as to be horizontal, the screw engagement groove 46d engages with the screw shaft of the screw 48. The fixing piece portion 46c is sandwiched between the screw head and the fixing support portion 2c to lock and hold the glass door 5 at an opening angle of 90 degrees. When the screw 48 is tightened in this state, the fixing piece portion 46c is The glass door 5 is fixedly held at the opening angle by being screw-fixed to the fixed support portion 2c. The glass door 5 is locked at another opening angle, for example, at the above-mentioned opening angle of 110 degrees by appropriately setting the length of the arm portion 46a in the fixing bracket and the bending angle of the fixed side portion 46c with respect to the arm portion 46a. It is also possible to configure to hold or fix.
[0029]
For example, as shown by a two-dot chain line in FIG. 5, the fixing bracket 46 is housed so that the fixing piece 46 c at the tip is located vertically below and along the left frame 52 </ b> L, or the fixing piece 46 46c is located vertically above and accommodated along the left frame portion 52L. Note that the fixed support portion 2c is formed so that only the region that abuts and supports the fixed piece portion 46c projects forward. When the arm portion 46a is swung at an open angle position near 90 degrees, the fixed support portion 2c is fixed. The front and rear edges of the portion 46c do not come into contact with the front frame around the fixed support portion 2c, so that the screw engagement groove 46c can be easily engaged. Further, by forming the fixed support portion 2c in a trapezoidal shape in a side sectional view, the above effect can be further improved.
[0030]
The operation of the door opening and holding mechanism 40 configured as described above will be described by taking as an example a case where the glass door 5 is opened and held at an opening angle of 90 degrees. The worker inserts the duplicate key into the lock portion of the locking device 4. Then, for example, the glass door 5 is unlocked by rotating counterclockwise, and a finger is placed on the side edge of the door frame 51 of the glass door which is opened so as to be lifted, and the glass door 5 is rotated by approximately 90 degrees. Open to the opening angle.
[0031]
Next, the locking fitting 41 accommodated and held on the locking hook 52f of the lower frame portion 52U is horizontally turned so as to be pulled out toward the user, and the leading end side of the holding rod portion 41a is guided onto the eave portion 17, and the glass door 5 is moved. The locking hole 41c at the tip of the holding rod portion is aligned with the locking protrusion 17a while finely adjusting the opening angle of the lock lever, and these are engaged and connected. As a result, the locking fitting 41 is stretched between the lower frame portion 52U and the eave portion 17 and locked, and the glass door 5 is held in an open state at an opening angle of 90 degrees. Therefore, the glass door 5 can be easily locked and held in the open state simply by the engagement operation of the locking fitting 41 as described above.
[0032]
On the other hand, when a stronger opening and holding is desired, in addition to the locking and holding of the glass door 5 by the locking metal 41, the locking and holding or fixing and holding of the glass door 5 by the fixing metal 46 are performed. When the fixing piece 46c of the fixing bracket 46 is stored vertically below, the glass door 5 is opened once to an opening angle exceeding 90 degrees, and the fixing bracket 46 is swung above the horizontal. In the retracted state, the locking and holding operation of the glass door 5 by the locking fitting 41 or the locking and holding operation of the glass door 5 by the fixing fitting 46 is performed in the retracted state. Any of these operations may be performed in advance. However, here, the description will be continued assuming that the locking fitting 41 has been locked and held by the locking fitting 41 while being retracted upward.
[0033]
As described above, when the locking hole 41c of the locking fitting 41 is engaged with the locking projection 17a, the glass door 5 is already held open at an opening angle of 90 degrees. Therefore, the operator swings the arm portion 46a of the fixture in the retracted position clockwise so as to lower the arm portion 46a so as to be horizontal. Then, the fixed piece portion 46c at the tip of the arm portion moves down from above the fixed support portion 2c with an arc trajectory, and the screw engagement groove 46d is engaged so as to receive the screw shaft portion of the screw 48, thereby fixing the fixed piece portion 46c. Enters between the screw head and the support surface of the fixed support portion 2c, and engages so as to be sandwiched between them. As a result, the glass door 5 is locked and held at the opening angle of 90 degrees by the fixing bracket 46. Further, by tightening the screw 48 from such an engaged state, the fixing piece portion 46c is screw-fixed to the fixing support portion 2c, and the glass door 5 is fixed and held at the opening angle. Accordingly, the glass door 5 can be easily locked and held at an open angle of 90 degrees by the engaging operation of the fixing bracket 46 as described above, and the screw 48 can be closed and fixed more firmly. Can be.
[0034]
In addition, since the swing direction of the locking member 41 and the swing direction of the fixing member 46 are set to be orthogonal to each other, a door opening / holding mechanism with increased resistance to external force can be obtained. For example, an external force acting to incline only the upper portion of the glass door 5 to the front acts to lift the tip side of the holding rod portion 41a of the locking metal member 41, and the engagement between the locking hole portion 41c and the locking protrusion 17a is released. Even if such a situation occurs, the engagement between the fixing bracket 46 and the screw 48 does not come off, and the open state can be stably maintained.
[0035]
In the illustrated locking member 41, a disc-shaped seat is provided on the turning shaft portion 41b to reduce the sliding area between the locking member 41 and the lower frame portion 52U so as to enable smooth horizontal turning. In addition, the nut 42 is disposed between the wall surfaces of the front and rear glass grooves (recess between the grooves) to prevent the nut 42 from loosening, but instead of providing such a seat or together with the seat, a resin-made resin is used. The washer may be used so as to be engaged with the male screw portion and sandwiched between the holding rod portion 41a and the lower frame portion 52U. Further, instead of the engagement connection between the male screw and the nut, a slit-shaped groove is provided in the turning shaft portion 41b and the engagement connection is performed using an E-ring or the like, or the engagement connection is performed using a fastening means such as a rivet. You may let it. Further, a configuration in which the locking fitting 41 is supported on the front frame 2 side so as to be able to turn horizontally and a locking projection or the like is provided on the lower frame portion 52U side, or a locking projection is provided on both the front frame side and the lower frame portion side is provided. It is good also as a structure which locks a metal fitting.
[0036]
Further, in the embodiment, for the convenience of drawing and explanation, an example is shown in which both the first opening and holding mechanism 40A and the second opening and holding mechanism 40B are arranged below the glass door 5, but the first or second opening and holding mechanism is provided. One of the holding mechanisms may be provided. In the case where both are provided, the second opening / holding mechanism 40B is disposed at a predetermined distance from the first opening / holding mechanism 40A and is disposed above the glass door 5, or A plurality of doors may be provided above and below the door 5. If the first open holding mechanism 40A and the second open holding mechanism 40B are arranged separately above and below the glass door 5, even if an external force biased above the glass door 5 acts, the glass door 5 can be stably maintained in an open state against external force in a well-balanced manner without twisting deformation. In addition, by providing a plurality of second opening / holding mechanisms 40B vertically, it is possible to obtain a door opening / holding mechanism capable of holding the opening state more firmly against a shocking external force in addition to a good support balance. Can be.
[0037]
The glass door 5 that is opened and held as described above is provided with a glass holding mechanism that facilitates the work of attaching and detaching the glass plate. Hereinafter, the glass holding mechanism 50 of the first embodiment will be described with reference to FIGS. 7 to 10.

Then, the left and right knurled screws 61 are finger-tightened to lock the lower protection frame 53 at the attachment / detachment angle position. At the attachment / detachment angle position, the screw portion of the knurled screw 61 is positioned at and engaged with the rear end of the tilt regulating hole 52c ', and the support surface portion 82a of the support plate abuts and is supported by the flank surfaces 52s of the left and right frame portions. Therefore, even if the worker does not support the lower protection frame 53, the lower protection frame 53 does not excessively tilt beyond the attachment / detachment angle position.
[0088]
The front and rear glass plates 54 are attached to the lower protection frame 53 locked at the attachment / detachment angle position in such a manner as to be engaged and held, and the upper protection frame 55 is attached so as to cover from above (FIG. 13 (A) → FIG. 13 (B)). Thereby, the glass plate 54 is protected so that the entire outer peripheral edge portion including the front surface and the rear surface is wrapped in the upper and lower protection frames 55 and 53, and an integrated glass assembly is formed.
[0089]
Next, the left and right knurled screws 61 fixed by finger tightening are loosened to tilt the glass assembly forward, so that the glass plate 54 is positioned at an upright angle position vertically above the window 51a. Then, the upper protection frame 55 is fixed using the above-described locking and holding mechanism (the locking and holding plate 57 or the locking and holding rod 72, etc.). Thus, the upward movement of the glass plate 54 and the upper protection frame 55 is restricted, and the glass assembly is fixed and held at the standing angle position.
[0090]
Then, the tilt fixing arm 86 is swung downward by using the operation knob 86m of the tilt fixing arm 86 pivotally connected to the left and right frame portions, and the pin locking groove 86c at the tip is engaged with the locking pin 84c of the link plate.

Accordingly, the swinging of the link plate 84 in the front-rear direction is regulated, and the tilting of the lower protection frame 53 is regulated, whereby the glass assembly is also fixed and held at the standing angle position in the present tilting support mechanism. Note that by fixing the left and right knurled screws 61, the fixing and holding at the upright angle position can be further strengthened.
[0091]
When the glass assembly is fixed and held at the standing angle position in this manner, the entire outer periphery of the upper and lower protection frames 55 and 53 is supported by the support plate 82, the left and right fixed support frames 52L and 52R, and the lock holding member (the lock holding plate 57 or the lock). The holding lot 72) is fixedly held to the door frame 51 so as to be surrounded by the holding lot 72), and even if a pressing force for moving the glass plate 54 up and down or a pressing force for falling down is applied from the front side of the door frame 51. The glass plate 54 is firmly locked and held against the pressing force.
[0092]
Therefore, with the glass holding mechanism 80 described above, the glass plate attaching / detaching operation can be facilitated and the glass plate attaching / detaching operation can be easily and safely performed similarly to the glass holding mechanisms 50 and 70 described above. A glass holding mechanism in which damage to a glass plate is reduced can be provided.
[0093]
