Description

[0001]
BACKGROUND OF THE INVENTION
The present invention belongs to the technical field of pachinko gaming machines, and particularly relates to a glass structure disposed in front of a game board.
[0002]
[Prior art]
In a pachinko gaming machine, a glass plate is placed in front of the game board, a space serving as a game area is formed between the glass board and the game board, and a game ball that is launched by the launching device and shot into the game area Normally, a game is played according to the behavior of the game, and if a winning or the like is established, the game ball (prize ball) is usually paid out. Therefore, although only one glass plate is necessary for the execution of the game, another transparent plate (usually a glass plate) is arranged on the player side, mainly in order to increase resistance against fraud. It was.
[0003]
These two glass plates are often held by glass rails and attached to a door-shaped front frame. However, by fixing the periphery of the two glass plates to a synthetic resin frame, There is a glass structure.
For example, in Japanese Patent Application Laid-Open No. 6-134122 (Patent Document 1), a frame is divided into a pair of upper and lower horizontal frames and a pair of left and right vertical frames, and is provided on each inner surface of the horizontal frame and the vertical frame. A composite glass plate having a structure in which a plate glass is fitted and inserted into two formed fitting grooves, and the horizontal frame and the vertical frame are integrally connected by engagement between the engaging portion and the engaged portion at each end. Is disclosed.
[0004]
The technique of this patent document 1 is a problem existing in the double glass assembly disclosed in, for example, Japanese Utility Model Publication No. 57-47012 (patent document 2), specifically, bonding each glass plate to a step portion of the frame. It is proposed to solve the problem that it takes time and labor to prevent the adhesive from protruding from the step portion, and it takes time and effort to manufacture, and the cost is inevitably high. .

[Problems to be solved by the invention]
Although the technique disclosed in Patent Document 1 can solve the problems related to adhesion in the double glass assembly of Patent Document 2, there has been a problem that the rigidity is insufficient and the shape becomes unstable.
[0007]
In the double glass assembly of Patent Document 2, since the frame and the glass plate are bonded to form an integral plate, the advantage is high in rigidity against tensile stress and bending stress, and the shape is stable. There is.
However, since the technique disclosed in Patent Document 1 excludes adhesion, rigidity such as the double glass assembly of Patent Document 2 cannot be obtained. It will bend like a bow.
[0008]
Of course, if the technique of Patent Document 2 (adhesion) is applied to the technique of Patent Document 1 to bond the frame and the glass plate, the above-mentioned lack of rigidity is eliminated and the shape is stabilized. However, this does not solve the problem related to adhesion in the double glass assembly of Patent Document 2, and the inventive step is also impaired.
[0009]
[Means for Solving the Problems and Effects of the Invention]
The glass structure according to claim 1,
A glass structure for a pachinko gaming machine in which a rectangular frame made of synthetic resin and a rectangular glass plate whose outer peripheral portion is fitted in a fitting groove provided on the inner peripheral side of the frame are integrated In the body,
At the bottom of the fitting groove, there is an adhesive injection groove corresponding to a range that includes the center part of the side of the glass plate that can be fitted to the fitting groove and does not include the end part. One for each side of the board,
One end of each adhesive injection groove communicates with an injection port opened on the outer surface of the frame body, and the other end communicates with a vent port opened on the outer surface of the frame body,
The frame body and the glass plate are bonded by an adhesive injected into the adhesive injection groove.
[0010]
In this glass structure, since the frame and the glass plate are firmly integrated by bonding, the rigidity is sufficient and the shape is stable (the problem of Patent Document 1 is solved).
In addition, the adhesive for bonding the frame and the glass plate may be injected into the adhesive injection groove from the injection port after the glass plate is fitted into the fitting groove of the frame body. Since it does not take time and the adhesive is injected into the adhesive injection groove, there is no possibility that it protrudes (the problem of Patent Document 2 is solved).
[0011]
In addition, the bottom of the fitting groove is a portion of the inner surface of the fitting groove that is in contact with the outer peripheral surface (cut surface) of the glass plate.
Since one adhesive injection groove is provided for each side of the glass plate, each side of the glass plate can be bonded to the frame, and the balance is improved and the rigidity is improved.
Moreover, since the adhesive injection groove is a groove corresponding to a range in which the center portion of the side of the glass plate that can be fitted to the outer periphery of the fitting groove is included and the end portion is not included, the glass plate is provided on each side. The central portion is configured to be bonded to the frame body by the adhesive injected into the adhesive injection groove.
The corner part of the rectangular frame has relatively high rigidity, but the side part, especially the central part, tends to lack rigidity. For example, it tends to deform when pulled, but that part should be bonded to the glass plate. Can increase the rigidity and prevent deformation.
In addition, one end of each adhesive injection groove communicates with an injection port that opens to the outer surface of the frame body, and the other end communicates with a vent port that opens to the outer surface of the frame body. When moving through the adhesive injection groove, the air in the adhesive injection groove escapes from the vent opening, so there is no resistance and the injection operation is easy and smooth. Further, if the injected adhesive reaches the vent port, the injection can be surely filled into the adhesive injection groove if the injection is finished.
[0012]
Note that there is no need to distinguish between the injection port and the vent port. If both ends of the adhesive injection groove are connected to holes opened on the outer surface of the frame body, one side is used for injection and the other side is used for air venting. It's good.
This glass structure may have a structure including two glass plates as in the glass structures of Patent Documents 1 and 2, but only the side facing the game board is a glass plate and the player side has a transparent rigidity. It is good also as a resin board (for example, acrylic board).
[0013]
Moreover, a glass structure is comprised with a frame and one glass plate, and the 2nd (player side) transparent plate (glass plate or synthetic resin plate) is good also as a different body from a glass structure. . In the case of using two glass plates, the glass structure of claim 2, that is, the glass structure of claim 1, wherein the frame is provided with two fitting grooves in parallel with each other, and the bonding is performed. An agent injection groove is also provided for each fitting groove, and a pair of glass plates are fitted into the two fitting grooves at the outer periphery, and the adhesive injected into the adhesive injection groove The structure may be bonded to the frame.
[0014]
Since the game area is almost circular, the glass plate can be made circular corresponding to this, but cutting it into a circle takes time and yield is not good.
Therefore, it is economical to make a rectangle such as a rectangle as described in claim 1.
[0017]
In addition, since the frame body is rectangular, the glass structure according to claim 1 or 2 according to claim 3 , wherein the frame body includes four parts of a pair of upper and lower horizontal frames and a pair of left and right vertical frames. Can be made into a frame shape by bonding them together .
With this configuration, the horizontal frame and the vertical frame may be injection molded as parts, so that the molding die can be small and the cost can be reduced.
[0019]
DETAILED DESCRIPTION OF THE INVENTION
Next, embodiments of the present invention will be described by way of examples of the present invention.
[0020]
【Example】
As shown in FIG. 1, the glass structure 10 includes a synthetic resin frame 12 and a pair of transparent glass plates 14 that are arranged substantially in parallel with each other and held by the frame 12.
[0021]
The frame 12 has a substantially square frame shape, and includes four parts, a pair of upper and lower horizontal frames 15 and 16 and a pair of left and right vertical frames 17 and 18, each of which is an injection molded product. The horizontal frames 15 and 16 are provided with a pair of connecting arms 15a and 16a forming a right-angled corner, and the ends of the connecting arms 15a and 16a are bonded to the ends of the straight vertical frames 17 and 18. A frame-like structure as shown in the figure is formed by welding (in this embodiment).
[0022]
As shown in FIG. 2, two fitting grooves 20 are provided on the inner peripheral side of the frame body 12, and the outer peripheral portion of the glass plate 14 is fitted in the fitting grooves 20.
The rail portion 21 provided with the fitting groove 20 has a U-shaped cross section, and the inner peripheral portions thereof are connected to each other by a lateral portion 27. In addition, a plurality of reinforcing ribs 26 are provided in a groove-shaped portion formed by both the rail portions 21 and the lateral portions 27.
[0023]
An adhesive injection groove 22 is provided on the bottom 20 a of the fitting groove 20. As shown in FIG. 3, the adhesive injection groove 22 has a length of about ３ of one side of the frame body 12 and is arranged at the center of each fitting groove 20. As shown in FIGS. 2 to 4 and 6, both ends of the adhesive injection groove 22 communicate with an external communication port 23 that opens on the outer surface of the frame body 12.
[0024]
As shown in FIGS. 2 to 4, the adhesive injection groove 22 is filled with an adhesive 24, and by this adhesive 24, the frame body 12 (the horizontal frames 15 and 16 and the vertical frames 17 and 18) and the glass plate 14. And are adhered. One of the external communication ports 23 paired for each adhesive injection groove 22 is used as an injection port and the other as a vent port when the adhesive 24 is injected.
[0025]
The glass structure 10 is attached to, for example, a front frame of a pachinko gaming machine and is disposed in front of the game board, and is used to form a space serving as a game area between the glass plate 14 on the inside and the game board. Is done. Therefore, the outer periphery shape and dimension of the frame 12 are made into the shape and dimension according to the structure for hold | maintaining the glass structure 10 of the pachinko game machine with which the glass structure 10 is mounted | worn. Further, if necessary, mounting projections, ribs, and the like may be provided on the outer periphery of the frame body 12.
[0026]
The glass structure 10 is assembled as follows.
First, as shown in FIG. 5, for example, the connecting arm 16a of one of the horizontal frames 15 and 16 (in this example, the horizontal frame 16) and the lower ends of the vertical frames 17 and 18 are bonded together to form a U-shape. The glass plate 14 is inserted from between the vertical frames 17 and 18, and the ends of the glass plate 14 are fitted into the fitting grooves 20 of the horizontal frame 16 and the vertical frames 17 and 18. Next, after the end of the glass plate 14 is fitted into the fitting groove 20 of the horizontal frame 15 which is the upper side of the frame 12, the connecting arm 15 a of the horizontal frame 15 and the upper ends of the vertical frames 17 and 18 are bonded. To do.
[0027]
Then, as shown in FIG. 6, for each adhesive injection groove 22, the injection nozzle 50 is inserted into one external communication port 23 to inject the adhesive 24.
Since the outer peripheral dimension of the glass plate 14 matches the inner peripheral dimension of the bottom 20a of the fitting groove 20 which is a series of the frame body 12 assembled, the outer peripheral surface (cut surface) of the glass plate 14 is the fitting groove 20. The adhesive injection groove 22 is a tunnel-like space.
[0028]
The adhesive 24 injected from the external communication port 23 flows toward the other external communication port 23 in the adhesive injection groove 22 having a tunnel shape. At this time, since the external communication port 23 at the destination is a vent port and the air in the adhesive injection groove 22 is released, the air in the adhesive injection groove 22 becomes a resistance and the injection work of the adhesive 24 is obstructed. It will never be done. That is, the adhesive 24 can be poured easily and smoothly.
[0029]
The injected adhesive 24 fills the adhesive injection groove 22 while reaching the clearance between the glass plate 14 and the fitting groove 20 and reaches the other external communication port 23 (vent port).
If the injection is terminated when the injected adhesive 24 reaches the vent port (for example, when it slightly overflows from the vent port), a sufficient amount of adhesive can be reliably filled into the adhesive injection groove 22.
[0030]
Since air escapes from the vent port and the adhesive 24 flows quickly, excessive adhesive 24 does not flow into the clearance, and the adhesive 24 passes through the clearance between the glass plate 14 and the fitting groove 20. It does not overflow outside the fitting groove 20 (the adhesive 24 does not protrude).
[0031]
When the adhesive 24 is solidified, the glass plate 14 and the frame body 12 (the fitting groove 20) are bonded to complete the glass structure 10.
The glass structure 10 is provided with an adhesive injection groove 22 at the bottom 20a of the fitting groove 20, and the frame body 12 and the glass plate 14 are bonded together by an adhesive 24 injected into the adhesive injection groove 22. Then, since the frame body 12 and the glass plate 14 are firmly integrated, the rigidity is sufficient and the shape is stable. Since the adhesive 24 injected into the adhesive injection groove 22 also enters the clearance between the fitting groove 20 and the glass plate 14 and bonds them together, the adhesion between the frame 12 and the glass plate 14 is extremely strong. Become.
[0032]
Two glass plates 14 are used for the glass structure 10, and two fitting grooves 20 are provided in the frame body 12 in parallel with each other. Since the glass structure 10 is further bonded to the frame body 12 by the adhesive 24 that is fitted in each of the grooves 20 and injected into the adhesive injection groove 22, the rigidity of the glass structure 10 is further increased.
[0033]
Since one adhesive injection groove 22 is provided for each side of the rectangular glass plate 14 and each side of the glass plate 14 is bonded to the frame body 12, the balance is improved and the rigidity is also improved.
Moreover, the glass plate 14 has a configuration in which the central portion of each side is bonded to the frame body 12 by the adhesive 24 injected into the adhesive injection groove 22, and the side portion of the rectangular frame 12 that tends to lack rigidity. In particular, the rigidity of the side portion, particularly the central portion of the side, can be satisfactorily prevented by the fact that the central portion of the side is bonded to the glass plate 14 to increase the rigidity.
[0034]
The adhesive 24 for bonding the frame body 12 and the glass plate 14 is injected from the external communication port 23 (injection port) after the glass plate 14 is fitted into the fitting groove 20 of the frame body 12. Since it is injected into the groove 22, it does not take time to bond. And since the adhesive agent 24 is inject | poured into the adhesive agent injection groove | channel 22, there is no possibility that this may protrude.
[0035]
In this injection operation, one of the paired external communication ports 23 serves as an injection port and the other serves as a vent port. Therefore, when the injected adhesive 24 moves through the adhesive injection groove 22, the adhesive injection groove 22. Since the air in the inside escapes from the vent port, there is no resistance, the injection operation becomes easy and smooth, and the pressure in the adhesive injection groove 22 increases, and there is no possibility that the adhesive 24 protrudes. Further, if the injected adhesive 24 reaches the vent opening, the injection can be surely filled in the adhesive injection groove 22 if the injection is finished.
[0036]
Furthermore, in this embodiment, the rectangular frame 12 is divided into four parts, ie, a pair of upper and lower horizontal frames 15 and 16 and a pair of left and right vertical frames 17 and 18, and these are bonded together to form a frame shape. Since it is a structure, a molding die can be small and a cost reduction is attained. Further, since the frame body 12 and the glass plate 14 are rectangular, the yield of the glass plate 14 is good and economical.
[0037]
Even if there is a variation in the thickness of the glass plate 14 or there is a processing error when cutting the glass plate 14, the glass plate 14 is bonded to the fitting groove 20. There is also an effect that it does not hit.
As mentioned above, although embodiment of this invention was described according to the Example, this invention is not limited to such an Example, and it cannot be overemphasized that it can implement variously in the range which does not deviate from the summary of this invention.
[0038]
For example, a method of injecting an adhesive or the like by providing an injection groove can also be used for assembling the frame. An example is shown in FIG. The connecting arms 15a and 16a of the horizontal frames 15 and 16 and the end portions 17a (18a) of the vertical frames 17 and 18 are stepped as shown in the drawing, for example, and injection grooves 15b (16b) are provided in the connecting arms 15a and 16a. . In the assembly of the frame body 12 described above, the connecting arms 15a and 16a and the end portion 17a (18a) are connected as shown in the figure, and then the welding agent (or adhesion) is opened from the opening of the injection groove 15b (16b). Agent) 15c is injected. The injected welding agent 15c flows along the injection groove 15b (16b) and permeates along the contact surface between the connecting arms 15a and 16a and the end portion 17a (18a). The frames 17 and 18 can be welded well. Since the welding is performed after the horizontal frames 15 and 16 and the vertical frames 17 and 18 are combined, the assembling work is facilitated.
