Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a composite glass plate for a pachinko machine, which has a structure in which two plate glasses are separated by a predetermined distance.

[0002]

2. Description of the Related Art Conventionally, as this type of composite glass plate for a pachinko machine, for example, one described in Japanese Utility Model Publication No. 57-47012 is known. This conventional composite glass plate is
Frame-shaped glass mounting frame is integrally formed with synthetic resin,
A step portion is provided around both end surfaces of the glass attachment frame, and plate glass is polymerized and adhered to each step portion with an adhesive to form an integrated structure.

[0003]

However, in the conventional composite glass plate for a pachinko machine, a large molding die is required to form a frame-shaped glass mounting frame,
In addition, it takes time and effort to bond each plate glass to the stepped portion of the glass mounting frame, and it is necessary to prevent the adhesive from leaking out of the stepped portion. There was a problem. The present invention is
The present invention has been made in view of such problems of the prior art, and an object thereof is to provide a composite glass plate for a pachinko machine that is easy to manufacture and inexpensive.

[0004]

In order to achieve the above object, a composite glass plate for a pachinko machine according to the present invention comprises a combination of a glass mounting frame formed of a synthetic resin in a frame shape and two plate glasses. The glass mounting frame is divided into a pair of upper and lower horizontal frames and a pair of left and right vertical frames, and two fitting grooves are provided on the inner surface of each of the horizontal frame and the vertical frame. The flat glass is fitted and the horizontal frame and the vertical frame are integrally connected by the engagement of the engaging portion and the engaged portion formed at the respective end portions.

[0005]

The composite glass plate of the present invention is configured such that the plate glass is fitted into the fitting grooves formed on the inner side surfaces of the pair of upper and lower horizontal frames and the pair of left and right vertical frames which form the frame-shaped glass mounting frame, and It can be manufactured by a simple operation of simply connecting the frame and the vertical frame by engagement. This eliminates the need for a large molding die for forming the frame-shaped glass mounting frame, and further eliminates the work of adhering the plate glass, thereby enabling a significant cost reduction.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS An embodiment of the present invention will be described below with reference to the drawings. In FIG. 1, a metal frame 4 is provided around a window hole 3 of the front frame 2 of the pachinko machine 1, and a front plate 6 having a glass frame 5 on one side of the metal frame 4 and a ball tray 7 on the front side is opened and closed. It is installed freely. The glass frame 5 covers the game area surrounded by the guide rails 9 of the game board 8, and the front plate 6 closes the lower launching portion of the game board 8 in an openable and closable manner. Also, on the back surface of the glass frame 5, 2
A glass holding frame 11 having two grooves 10a and 10b opening inwardly so as to hold a sheet of glass is fixed (see FIG. 7).

FIG. 2 is a perspective view of a composite glass plate according to an embodiment of the present invention, and FIG. 3 is an exploded perspective view thereof. The composite glass plate 12 is roughly composed of a glass mounting frame 13 formed of a synthetic resin in a frame shape and two plate glasses 14a and 14b. The glass mounting frame 13 includes a pair of upper and lower horizontal frames 15a and 15b and a pair of left and right vertical frames 16 as shown in FIG.
It is formed by dividing into a and 16b.

The pair of upper and lower horizontal frames 15a, 15b are formed in a U shape with both sides bent inward, and the pair of left and right vertical frames 16a, 16b are formed in a rod shape. And
Two fitting grooves 17, 17 into which the peripheral edges of the plate glasses 14a, 14b are fitted are provided on the inner surface of each of the horizontal frames 15a, 15b and the vertical frames 16a, 16b, and the outer surface of the glass holding frame 11 is inserted. Two projecting edges 18, 18 that fit into the grooves 10a, 10b are formed.

As shown in FIGS. 3 to 5, engaged portions 21a and 21b composed of a keyhole-shaped concave portion 19 and a square tubular portion 20 are provided at both bent ends of the horizontal frames 15a and 15b. Formed,
Engagement portions 24a and 24b composed of a prismatic portion 22 and a connecting piece 23 are formed at both upper and lower ends of the vertical frames 16a and 16b. The connecting piece 23 is formed thin so as to have elastic force, and a projection 25 is provided on the inner surface of the tip thereof.

The horizontal frame 15a (15b) and the vertical frame 16 described above
As shown in FIG. 5, the a (16b) is first a vertical frame 16a (1
6b) to the rectangular column portion 2 of the horizontal frame 15a (15b).
0 and then the projection 25 of the connecting piece 23 is inserted into the recess 19
Then, the glass mounting frame 13 having an integral structure is assembled by fitting it to each other and connecting them to each other.

FIG. 6 shows a procedure for assembling the composite glass plate 12. For the assembly, first, as shown in FIG. 6A, the lower ends of the left and right vertical frames 16a and 16b are connected to both ends of the lower horizontal frame 15b. Next, as shown in FIG. 6B, the two plate glasses 14a and 14b are fitted into the fitting grooves 17 and 17 from above.
6C, the vertical frames 16a, 16 are inserted as shown in FIG. 6C.
It is achieved by connecting the upper lateral frame 15a to the upper end of b.

The composite glass plate 12 thus constructed has a lower horizontal frame 15b and left and right vertical frames 16a,
The two projecting edges 18, 18 formed on the outer surface of 16b are inserted into the grooves 10a, 10b of the glass holding frame 11, and the crime prevention frame rod 25 that is detachable from the glass holding frame 11 is fitted from above. Insert and fix.

[0008]

As described above, in the composite glass plate for a pachinko machine of the present invention, a frame-shaped glass mounting frame for supporting two plate glasses by separating them for a certain period of time is provided with a pair of upper and lower horizontal frames and a pair of left and right vertical frames. Since it is formed by dividing into a frame and integrally assembled by engaging the engaging portion and the engaged portion provided at both ends thereof, A large-scale molding die for forming a frame-shaped glass mounting frame is completely unnecessary and can be manufactured at low cost. Also,
Since each plate glass is inserted and held in the fitting groove of the glass mounting frame, there is no need to use an adhesive or an adhesive work, so that the assembly is not troublesome, and the plate glass may be soiled by the adhesive. Can be resolved.
