As a result, the strength, especially the rigidity as the transparent panel structure 10, does not become insufficient. <P>COPYRIGHT: (C)2008,JPO&INPIT

Description

  The present invention belongs to the technical field of ball game machines, and particularly relates to a transparent plate structure disposed in front of a game board.

  In a ball game machine such as a pachinko machine, a transparent plate (in many cases, a glass plate) is disposed in front of the game board, and a space between the transparent board and the game board is used as a game area. Further, for the purpose of countermeasures against illegal acts, another transparent plate is usually arranged in front of the transparent plate for defining a game area, that is, on the player side. Therefore, a normal ball game machine is equipped with two transparent plates.

There is a transparent plate structure in which these two transparent plates are arranged in parallel at intervals and the outer peripheral portion thereof is fixed to an attachment frame to form an integral structure.
For example, in the composite glass plate disclosed in Japanese Utility Model Publication No. 57-47012 (Patent Document 1), a frame-shaped glass mounting frame is integrally formed of synthetic resin, and stepped portions are provided on both end faces of the glass mounting frame. Then, a plate glass is polymerized and bonded to each step portion with an adhesive to form an integral structure.

Japanese Patent Laid-Open No. 06-134122 (Patent Document 2) discloses that two sheet glasses are attached by a glass mounting frame formed in a frame shape by combining a horizontal frame and a vertical frame provided with two fitting grooves. A holding and integrated structure is disclosed.
Japanese Utility Model Publication No. 57-47012 Japanese Patent Laid-Open No. 06-134122

  When the frame-shaped mounting frame is integrally formed as in Patent Document 1, there is a problem that the molding die is enlarged. On the other hand, if the mounting frame is formed into four parts as in Patent Document 2, an increase in the size of the mold can be avoided, but a step of connecting the horizontal frame and the vertical frame to each other is required.

Moreover, when it is the structure which adhere | attaches an attachment frame and a glass plate like patent document 1, there exists a problem as described in patent document 2. FIG.
On the other hand, in the technique of Patent Document 2, since the attachment frame and the glass plate are not bonded, problems due to bonding can be avoided. However, since there is a manufacturing error in the thickness of the glass plate, the glass plate and the fitting groove do not adhere to each other, and rattling occurs. In addition, since the glass plate and the fitting groove can be relatively moved without being in close contact with each other, the strength, particularly rigidity, of the transparent plate structure may be insufficient.

The transparent plate structure for a ball game machine according to claim 1,
In the transparent plate structure for a ball game machine that has an integral structure by fixing the outer peripheral portion of two rectangular transparent plates arranged in parallel at intervals to the mounting frame,
Three sides of the mounting frame are configured in series with an extrusion mold material of aluminum or aluminum alloy provided with two fitting grooves for fitting the outer peripheral portions of the two transparent plates,
A synthetic resin gap filler is interposed between the fitting groove and the outer peripheral portion fitted thereto, and the outer peripheral portion is fitted into the fitting groove.

In this transparent plate structure for a ball game machine, the three sides of the mounting frame are formed in series by an aluminum or aluminum alloy extrusion mold material, so there is no need to use a large molding die.
The members constituting these three sides (hereinafter also referred to as “three-side members”) and the members constituting the remaining one side of the mounting frame (hereinafter also referred to as “one-side members”) are separate members. The step of connecting the two members is essential, but the connecting operation is simple compared to the quadrant structure as in Patent Document 2.

Further, as described in claim 2, even when the remaining one side of the mounting frame is formed of a synthetic resin molding material, the mold for that purpose can be small.
The connection between the three-sided member and the transparent plate is only to fit the outer peripheral portion of the transparent plate into the fitting groove of the three-sided member, but a synthetic resin gap filler is provided between the fitting groove and the outer peripheral portion. Therefore, even if there is a manufacturing error in the thickness of the transparent plate, the transparent plate and the fitting groove can be securely and securely fitted. Since the transparent plate and the three-sided member are integrated by fitting, the strength as the transparent plate structure, in particular, the rigidity does not become insufficient. Of course, no rattling occurs.

  Thus, since the transparent plate is securely fitted and held in the fitting groove of the three-sided member, the one-sided member only needs to be connected to the three-sided member, and the fitting with the transparent plate is somewhat loose. There is no problem. In addition, since the one-side member and the transparent plate do not necessarily have to be fitted, the one-side member may be a simple plate shape.

Moreover, since the bonding between the three-sided member and the one-sided member and the transparent plate is unnecessary, a problem caused by the bonding does not occur.
The synthetic resin used as the gap filling material is not limited as long as it can be elastically deformed or plastically deformed when the outer peripheral portion of the transparent plate is fitted into the fitting groove.

  The transparent plate structure for a ball ball game machine according to claim 3 is the transparent plate structure for a ball ball game machine according to claim 2, wherein the remaining one side of the mounting frame is the two transparent plates. It is characterized by comprising a synthetic resin molding material provided with two fitting grooves for fitting the respective outer peripheral parts.

  When molding one side member having a fitting groove with synthetic resin, if the width of the fitting groove is equal to or slightly smaller than the thickness of the transparent plate, the transparent plate and the fitting groove of the one side member are formed. Since it can be made to fit reliably, shakiness does not arise.

  Although there is no special limitation in the connection structure of a 3 side member and a 1 side member, it is easy to connect using a screw like Claim 4.

Next, embodiments of the present invention will be described based on examples of the present invention. The present invention is not limited to the following examples and the like, and it goes without saying that the present invention can be implemented in various ways without departing from the gist of the present invention.
[Example]
As shown in FIG. 1, the transparent plate structure 10 of this embodiment includes a mounting frame 13 including a U-shaped three-sided member 11 and a linear one-sided member 12.

  Both the three-sided member 11 and the one-sided member 12 are made of an aluminum alloy extruded mold provided with two parallel fitting grooves 14, 14. The three-sided member 11 bends the extruded mold in a U-shape. The one-sided member 12 is obtained by cutting an extruded mold material into an appropriate length. Then, the three-sided member 11 and the one-sided member 12 are connected by screws 15 at both ends of the one-sided member 12 to form a frame-shaped mounting frame 13.

  As shown in an enlarged view in FIG. 3, a gap filler 16 is fitted in the fitting grooves 14, 14 of the three-sided member 11. The gap filling material 16 is composed of a pair of groove fitting portions 17 which are U-shaped in cross section and fitted into the fitting grooves 14 and 14, and a flat plate-like connecting portion 18 provided between them. It is a molded article of resin (for example, ABS, polyethylene, polypropylene, polyvinyl chloride, polyurethane, etc.). The gap filling material 16 is mounted on each side of the three-sided member 11 so as to cover the two fitting grooves 14 and 14 and the convex portion therebetween, and a plurality of places are fixed with screws 19. . In addition, the corner part and both ends of the three-sided member 11 are separated from the gap filler 16 (not mounted).

  The outer peripheral portions of the two glass plates 20 are fitted into the groove fitting portion 17 of the gap filler 16. Further, the gap filler 16 is not attached to the one side member 12, but the outer peripheral portion of the glass plate 20 is inserted into the fitting grooves 14 and 14.

  In addition, since the corner part of the three-sided member 11 is curved not in a right angle but in an arc shape, if the corner of the glass plate 20 is a right angle, it interferes with the corner part, so this part is a corner cut 20a. . That is, the glass plate 20 is not exactly rectangular, but since the corner cut 20a is hidden in the fitting groove 14, it is rectangular in appearance.

  Needless to say, the width of the fitting grooves 14 and 14 is larger than the thickness of the glass plate 20, but the width of the groove fitting portion 17 in a state where the groove fitting portion 17 is fitted in the fitting groove 14, that is, the glass plate. The width of the gap for fitting 20 is set to be slightly smaller than the thickness of the glass plate 20. For this reason, the outer peripheral part of the glass plate 20 is fitted into the fitting groove 14 via the groove fitting portion 17, and the glass plate 20 and the three-sided member 11 are integrated by this fitting.

  In order to assemble the transparent plate structure 10, first, the gap filler 16 is attached to the three-sided member 11, and the glass plate 20 is inserted from the open portion of the three-sided member 11 (the portion to which the one-sided member 12 is attached). Thus, the outer peripheral portion of the glass plate 20 is fitted into the groove fitting portion 17 in the fitting grooves 14 and 14.

  At this time, the glass plate 20 slides in the groove fitting portion 17 on the two opposite sides of the three-sided member 11, but the gap filling material 16 is stopped by the screw 19, so that the gap filling is performed. There is no possibility that the material 16 will shift.

  Further, the width of the groove fitting portion 17 is set slightly smaller than the thickness of the glass plate 20, but the groove fitting portion 17 is elastically deformed, and the three-sided member 11 also has the width of the fitting groove 14. Since it can be elastically deformed so as to spread, it is not difficult to insert the glass plate 20 while sliding in the groove fitting portion 17.

  Then, the glass plate 20 is surely pushed into the closed side portion of the three-sided member 11 (side portion facing the one-sided member 12), and the portion is fitted into the groove fitting portion 17 so as to be fitted. The one side member 11 is aligned with the three side member 11 so that the remaining one side of the glass plate 20 is inserted into the fitting groove 14 of the one side member 12, and both ends of the one side member 12 are screwed to the screw 15. The three side members 11 are connected. Thereby, the assembly of the transparent plate structure 10 is completed.

  The transparent plate structure 10 is used by being mounted on a ball game machine such as a pachinko machine, similar to the composite glass plate described in Patent Document 1 or Patent Document 2, Since it is sufficient to follow a known technique, the description is omitted.

  As described above, the transparent plate structure 10 is used for a ball game machine that has an integral structure by fixing the outer peripheral portion of two rectangular glass plates 20 arranged in parallel at a distance to the mounting frame 13. In the transparent plate structure 10, an aluminum alloy extruded mold member provided with two fitting grooves 14 for fitting the three outer sides of the two glass plates 20 on the three sides of the mounting frame 13. A glass resin is formed in the fitting groove 14 by interposing a synthetic resin gap filler 16 (groove fitting portion 17) between the fitting groove 14 and the outer peripheral portion of the glass plate 20 fitted thereto. In this configuration, the outer periphery of the plate 20 is fitted.

Since the three-sided members 11 constituting the three sides of the mounting frame 13 are formed in series by an aluminum alloy extrusion mold material, it is not necessary to use a large molding die.
In the embodiment, the remaining one side (one side member 12) of the mounting frame is also made of an extruded material of aluminum alloy. However, even when this is made of a synthetic resin molding material, the mold for that purpose is small. Just do it.

  The connection between the three-sided member 11 and the glass plate 20 is merely to fit the outer peripheral portion of the glass plate 20 into the fitting groove 14 of the three-sided member 11, but it is synthesized between the fitting groove 14 and the outer peripheral portion. Since the resin gap filler 16 (groove fitting portion 17) is interposed, the glass plate 20 and the fitting groove 14 (groove fitting portion 17) can be reliably secured even if there is a manufacturing error in the thickness of the glass plate 20. And can be strongly fitted. Since the glass plate 20 and the three-sided member 11 are integrated by fitting, the strength, in particular, the rigidity as the transparent plate structure 10 is not insufficient. Of course, no rattling occurs.

  Thus, since the glass plate 20 is firmly fitted and held in the fitting groove 14 of the three-sided member 11, the one-sided member 12 only needs to be connected to the three-sided member 11. There is no problem even if the fitting is loose. Since the one-side member 12 and the glass plate 20 do not necessarily have to be fitted, the one-side member 12 may have a simple plate shape.

In addition, since the bonding between the three-sided member 11 and the one-sided member 12 and the glass plate 20 is unnecessary, a problem caused by the bonding does not occur.
[Modification]
As illustrated in FIG. 4A, the gap filler may be a U-shaped member having a flat plate-like connecting portion 18 and a plate-like groove fitting portion 17 a depending from both edges thereof. Good.

Further, as illustrated in FIG. 4B, it is configured only by a U-shaped member 16 a corresponding to the groove fitting portion 17 of the embodiment (without the connecting portion 18), and each fitting groove 14. It may be configured to fit.
[Others]
One side member of the mounting frame 13 may be formed of a synthetic resin molding material. In that case,
One side member may be provided with two fitting grooves 14 or may have a plate shape without the fitting grooves 14.

  In the embodiment, the gap filler 16 is attached to each side of the three-sided member 11 one by one, but the length along the side of the three-sided member 11 is shorter than that of the example (for example, A plurality of gap fillers may be attached to each side using a structure in which the gap filler 16 is divided into a plurality of parts.
