BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an open / close connection support structure for a machine in a pachinko gaming machine, and more specifically, in a pachinko gaming machine that can be used for pachinko gaming in a vertical orientation, holding an outer shell forming the machine body of the machine. The present invention relates to an open / close connection support structure for assembling and supporting an outer frame for a frame and a front frame for an open / close mounting frame.

[0002]

2. Description of the Related Art In a gaming machine of this type represented by a pachinko machine, as is well known, as a machine body, it is manufactured as a vertical rectangular frame having a standard external size and having proper strength, which is also used as a fixing outer frame. An outer frame, and a front frame manufactured as a vertically long rectangular frame having an appropriate size that is also an open / close mounting frame for various game components and has an appropriate strength, and matches the opening front surface area of the outer frame. Generally, both frames are assembled and releasably assembled and locked by utilizing the opening / closing connecting and supporting means on the upper left and lower sides of the front side and the locking device on the right side of the front side. When performing the game in a game hall, etc., the outer frame is fixed and held at a predetermined vertical tilt angle on the installation frame base, which is usually called an "island," and the front side of the opening of this outer frame is fixed. The entire front frame unit equipped with various game components (including a game board) is assembled to be used as a vertical ball game machine for each game.

Therefore, in such a vertical type game machine, in the game playing state, the front frame is long and stable with respect to the outer frame, and can be appropriately opened / closed and connected, and by extension, the entire front frame unit. It is important that the game components are held rotatably in an appropriate posture, and that various game components related to the passage of balls, the game board, and the like are fixedly held at the original set positions. Therefore, in order to deal with this, in the conventional open / close connection support means for the fuselage, as a most commonly used concrete example, it is fixed to the upper left side and the lower side of the outer frame, which is usually called a hinge type. Adopting a connecting support fitting with a support shaft and a connecting hook fitting with a shaft hole fixed on the upper left and lower parts of the front frame, the support shaft and shaft hole in each pair of means are directly inserted and connected. It is supposed to be done. When viewed from the open / closed posture of the front frame with respect to the outer frame, the lower open / close connection support means serves as a support reference for receiving a large total load of the entire front frame unit, and therefore its support strength and stability are strongly required. Has been.

[0004]

By the way, with regard to the opening and closing connection support means for the machine body in this type of gaming machine, the support metal fittings and the hanging metal fittings that form a pair (set) with each other in either upper or lower means, Manufactured from a metal plate material with a required thickness based on press forming, supporting shafts of a predetermined diameter are fixed to each horizontal part, shaft holes are penetrated, and each metal fitting is an outer frame. Then, it is firmly fixed to each installation portion of the front frame in a predetermined direction (posture) with a plurality of screws or the like. However, there is a considerable diameter difference (gap) between the outer diameter of the support shaft and the inner diameter of the shaft hole in both the upper and lower fittings, and at the current stage, both are within the tolerance range set by mechanical engineering. It is very difficult to stop. Therefore, when viewing the front frame assembled to the outer frame when the gaming machine is in the operating state, due to the gap between the support shaft and the shaft hole in the upper and lower means, which is fitted and connected as described above, Long and stable suitable support cannot be achieved,
Rattling that occurs all the time prevents smooth opening and closing.

In particular, in the lower opening / closing connection support means, since the total load of the entire front frame unit is largely received, the support shaft may be deflected due to backlash. Despite the fact that it should serve as a standard for mounting and supporting the front frame in an appropriate posture with respect to the outer frame, maintain a suitable connection support such as a centered state due to the gap between the support shaft and the shaft hole. I couldn't. Even in the case of a synthetic resin molded front frame that has been proposed in recent years, since it is a type that uses the separately manufactured connection support / hanging bracket as described above, it causes connection failure of both frames. There's a problem. For that reason, there has been a long-awaited proposal of a technology capable of maintaining a long and stable and suitable connection support of both frames.

[0006]

SUMMARY OF THE INVENTION The present invention has been proposed in order to preferably solve the above-mentioned problems, and is a synthetic resin molding forming an outer frame which constitutes an outer frame holding frame of an airframe and an open / close mounting frame for various game constituent members.

It is characterized in that it is set as a reference position for a horizontal mounting posture.

[0008]

The outer frame forming the outer frame holding frame and the front frame on which the game components are mounted are connected and detachably and openably connected by the open / close connecting and supporting means arranged above and below the common one side edge. , Is closed and held by a locking device installed inside the common other side edge. A bearing sleeve made of synthetic resin, which was fitted into the support hole in the bearing boss-shaped engaging part that was integrally molded in the lower left corner of the front frame, was erected and fixed at the upper left corner of the lower frame member in the outer frame. By fitting and connecting the support shafts, both frames are stably assembled and supported without rattling. Further, when the two frames are assembled through the opening / closing connection support means, the positioning seat formed on the outer periphery of the lower part of the bearing sleeve comes into contact with the upper surface of the lower frame member and the lower surface of the engaging portion, so that the positioning seat is fitted to the outer frame. Can be used as a reference position for the horizontal posture of assembling the front frame.

[0028]

Operation of the embodiment In the pachinko gaming machine of the above-described embodiment, first, an example of an assembling mode of both frames A and B forming the machine body will be described. That is, the front frame B is held at a slightly higher position with the front frame B opened with respect to the outer frame A that is stationary and held in a vertical posture on the floor surface or the like. Then, in the upper opening / closing connecting / supporting means C, the bearing sleeve 47 of the engaging portion 45 is temporarily fitted and positioned with respect to the spindle 43 from above, and under this, in the opening / closing connecting / supporting means C below, the shaft 54 is attached. The bearing sleeve 58 of the engaging portion 56 from above. By lowering the front frame B in this state, the sleeves 47 and 58 are closely fitted and inserted into the support shafts 43 and 54 of the upper and lower means C and C, respectively.
The front frame B is connected to and supported by the outer frame A while being properly centered. This assembling can be easily performed because the upper support shaft 43 is appropriately longer than the lower support shaft 54.

Next, the front frame B is opened and closed by opening and closing the upper and lower support shafts 43 and 54.
After closing the outer frame A as the center of rotation (rotation) and the lower end surface of the front frame B on the side opposite to the fulcrum portion is located at the horizontal upper end surface of the lower frame member 4 of the outer frame A, the front frame B is appropriately strengthened. Push in. As a result, the upper and lower hooks 39, 39 of the locking device 37
The lock receiving metal fitting 4 of the outer frame A with its own deformation.
The front frame B is locked and held by the outer frame A in a closed state by engaging with 0 and 40.

As a result, in the assembled state of both frames A and B, the lower surface of the positioning seat 59 of the bearing sleeve 58 in the lower means C is the horizontal upper end surface of the support portion 51 (the support shaft 5 in the figure).
4 and the horizontal support means E.
While the support seat 26 of the front frame B in the above-mentioned contacts the receiving seat 8 of the lower frame member 4, the inside of the lower end of the front frame B is positioned in the contact rod 9. Therefore, the entire front frame B is stably supported by the front support rod 6 of the lower frame member 4 in a proper horizontal state in an appropriately floating state. Further, the pressing piece 44 of the connecting fitting 41 of the above means C
However, the upper end surface of the front frame B is pressed against or in contact with the upper surface of the locking seat 48 to suitably prevent the front frame B from moving upward.

On the other hand, in the assembled state of both frames A and B, in the engaging support means D and D of each part, the upper and lower left side engaging support pieces 61 and 61 are respectively attached to the inner side surfaces 3a and 7a on the left side of the outer frame A. The upper and lower right engaging support pieces 61, 61 are brought into contact with or abut on the inner side surfaces 3a, 7a on the right side of the outer frame A, respectively. As a result, rattling of the entire front frame B with respect to the outer frame A in the left-right direction is properly suppressed. Therefore, for pachinko game machines, for example, when storing (stocking) in a manufacturing plant, when transporting vehicles, and when carrying in and transferring to game halls and parts, the machine itself is placed sideways (sideways). When stacked or handled, the outer frame A preferably supports the entire front frame B side.

That is, in the sideways state, the entire front frame B side tries to lower with respect to the outer frame A, and the total load accordingly always acts downward. In such a state, in the lateral state in which the open / close coupling support means C, C is on the lower side or the upper side, the engagement support means D, D on the side to be displaced to the left and right sides is engaged. The support pieces 61, 61 are the outer frame A.
The inner side surfaces 3a, 7a displaced downward are respectively engaged. For this reason, the total load of the entire front frame B, whichever the sideways direction, is,
3 and the left or right connecting plates 7, 7 of the lower frame member 4 act directly. Further, when the machine itself is raised from the horizontal direction to the vertical direction, even if the lower left or lower right corner of the lower frame member 4 of the outer frame A may once hit the floor surface, the respective engaging support means. Since D and D are in the engaged state, the total load on the front frame B side acts on each part of the outer frame A.

Therefore, the engaging and supporting means D, D of the above-mentioned respective parts
As a result of the engagement support action by the outer frame A, the outer frame A directly bears most of the total load of the front frame, whereas the open / close coupling support means C, C significantly reduce the total load of the front frame. The small external force is applied, and the action of the large external force in the shearing direction is avoided. As a result, the deformation and looseness of the support shafts 43 and 54 in the means C and C, the deformation and crack damage of the support portion 51 and the engaging portions 45 and 56, and the deformation of the hanging metal members 39 and 39 of the locking device 37 are eliminated. To be done.

As described above, the pachinko game machine having the outer frame A and the front frame B that are assembled and held as a machine body is vertically installed on the installation frame base F in the game hole in its implementation. It is used for games as a ball game machine. In this state, the entire front frame B is properly and stably connected to and supported by the outer frame A, and can be smoothly opened and closed without rattling, and is closed while being maintained in a proper horizontal posture. The set is retained.

Here, the installation of the game machine will be additionally described. That is, on each surface side (generally referred to as "row") of the installation frame base F, in the gaming machine of each base, the entire front frame B side is assembled to the outer frame A fixed at a required tilt angle to play the game. The state where the board 32 is properly tilted backward is in a normal and proper posture. The inclination of the entire gaming machine is set based on how much the upper end side is displaced rearward with respect to the lower edge front edge with reference to the vertical state. By the way, for the displacement amount,
It is also called "minutes and minutes".

In such a background, in the pachinko gaming machine of this embodiment, the outer frame A can be tilted and fixed to the installation frame base F as follows. That is, as partially illustrated in FIG. 6, as the alignment of the outer frame A placed on the installation frame base F, the alignment position of the lower end edge (which is the lower end front edge of the lower frame member 4) P ₁ is received under While aligning with the reference position P of the plate 71, although not shown, the alignment position of the upper end (the front end edge of the upper rod 2) is appropriately displaced rearward with respect to the reference position of the upper plate 72, and an angle measuring device (illustration is shown). Set the tilt angle of the entire frame by (No). Under this condition, the upper rod 2 of the outer frame A is nailed and fixed to the upper plate 72.

Next, while the lower alignment position P ₁ of the outer frame A and the reference position P of the lower support plate 71 are adjusted and held in order, both angles of the lower frame member 4 are set. Fixing mechanism M, M
It is fixed on the lower receiving plate 71 by. That is, as shown in FIG. 5 and FIG.
8 is aligned with, for example, the "0" point position of the scale 19, and the locking tooth bands 12, 12 of both rows are positioned and meshed with each other through the teeth 13, 15. And set screw 17 to fixed board 1
4 is inserted into the long hole 11 from the hole 16 and is deeply screwed into the lower receiving plate 71, and the fixing plate 14 is strongly tightened from above to directly press and fix the lower rod 5. As a result, the outer frame A is tilted and fixed, and the front frame B side is assembled to this, so that the entire gaming machine is installed at a required tilt angle.

When the game machine installed as described above is changed and adjusted to another angle, first, the set screw 17 is loosened a little and the engagement between the engaging tooth belt 12 and the fixed platen 14 is temporarily released, The lower frame member 4 of the outer frame A is moved in either the front or rear direction. As a result, as illustrated in FIGS. 7 (a) and 7 (b),
The lower frame member 4 is relatively moved via the elongated hole 11 with respect to the set screw 17 that is still screwed and fixed to the lower receiving plate 71 of the installation frame base F. This movement adjustment is performed while observing the displacement of the scale 19 with respect to the pointer 18 of the fixed platen 14, and is changed and adjusted from the "0" point reference to any one of the numerical values "1 to 5". As a result, the tilt angle of the outer frame A is determined.

After setting the angle of the outer frame A, the set screw 1

[0041]

As can be understood from the above embodiment,
In the open / close connection support structure of the machine body in the pachinko gaming machine of the present invention, the outer frame forming the outer frame holding frame and the front frame on which the game component members are mounted are arranged at the upper left end and the lower end on the front left side. It is detachably and openably connected and supported by the opening and closing connection support means, and is closed and held by a locking device inside the front right side. Since the opening and closing connection support means of the lower end portion has a structure in which the bearing sleeve is fitted into the engaging portion of the front frame to form the shaft support hole, the total load of the game components and the like mounted on the front frame and the front frame. It is possible to eliminate the adverse effects of the opening and closing connection support portions of both frames, that is, bending deformation and backlash of the support shaft, and crack damage and deformation of the boss portion made of synthetic resin. It is possible to maintain the proper condition by properly and firmly assembling and holding. Further, since the positioning seat is formed in the lower part of the bearing sleeve, the front frame side can be smoothly connected to and supported by the outer frame so that the front frame can be smoothly opened and closed. The connected support is made.

On the other hand, since the front frame is made of synthetic resin,
Not only installation parts and openings related to various game components, but also engaging parts that constitute the opening and closing connection support means of the upper and lower ends, a support seat to be formed on the lower right side surface, and a recessed part on the upper left side. Since the locking seat and the like to be formed can be integrally formed with the front frame, simplification of manufacturing the front frame itself and cost reduction can be achieved, and improvement in quality and mass productivity of the gaming machine can be expected.
