Description

[Detailed description of the invention] The present invention relates to a tank for storing prize balls in a pachinko machine.In particular, this invention involves molding the main tank part of the storage tank into two parts, a base body and a frame body, separately. By combining these two, a storage tank with a complex structure can be easily molded from plastic, and by making the above-mentioned frame combination freely removable, it is possible to create a storage tank with a complex structure that can be easily molded from plastic. To provide a storage tank for a Pachinko machine which allows maintenance and inspection work to be easily and quickly performed by opening the upper surfaces of a rectifying part and a ball supply gutter provided therein.

This invention will be described below based on illustrated embodiments, and its features will be explained in detail.

Fig. 1 is a front view showing a state in which a storage tank 2 according to the present invention is provided on the back side of a base frame 1 housed in the machine frame of a pachinko machine, Fig. 2 is an enlarged plan view of the main parts, and Fig. 3 The figure is a cross-sectional view taken along the line -, FIG. 4 is a cross-sectional view taken along the line -, and FIG. 5 is an enlarged exploded perspective view of the main parts.

The base frame board 1 is a metal plate here, and the front part houses a game board in a tangential manner, and the back part includes a tank 2 for storing prize balls, and the ball hit to the game board is stored in the game board. Safe ball detection device 3 that collects safe balls that fly into the prize opening provided in The assembled mechanism frame 4 includes a game stop device 5 that stops the game when there is insufficient prize balls in the storage tank.
A cover 6 etc. that covers the is assembled.

Since the storage tank 2 guides prize balls to the prize ball device, it is installed at a higher position than the prize ball device.

As shown in FIG. 2 and FIGS. 5 and 6, this storage tank consists of a base body 2a and a frame body 2 which cooperates with the main body of the tank by being assembled to this base body.
It consists of b. The base body 2a has a wall part 7 forming the back wall part of the main tank at the upper part, a spherical rectifying part 8 which is integrally formed in series with the lower part of the wall part,
It has a ball supply gutter 9 provided so as to be continuous with this rectifying part, and the other frame body 2b has a front wall part 10,
It is integrally formed with left and right side wall portions 11, 12, and a bottom wall portion 14 with a ball drop opening 13 provided at the left end, and is formed into a box shape lacking a top surface and a back surface.

The wall portion 7 of the base body is partially set back to form a recess 15, and a vertical fitting groove 16 is provided on the right side of this recess, and a vertical fitting groove 17 is provided on the left side of the wall portion. are set up in parallel. The rectifying section 8 is integrally provided so as to protrude from the front surface of the extension wall section 7' extending below the wall section 7, and a ball supply gutter 9 is similarly provided thereon.

The rectifying section 8 is a section that regulates the pressure of the balls falling from the main body of the tank before reaching the ball supply gutter 9 and rectifies the flow. The supply gutter 9 is provided closer to the right.

The rectifying section 8 and the ball supply gutter 9 have open upper surfaces, and their bottom surfaces have a gentle downward slope from the left end of the rectifying section 8 to the right end of the gutter 9. A detection step plate 18 that detects a lack of balls and activates the game stop device 5 is rotatably supported on the bottom surface of the rectifying section, and forms part of the bottom surface of the ball supply gutter 9. is formed into two passages by a partition wall 19 standing longitudinally in the center and continues to the prize ball device.

Now, the other frame 2b has left and right side walls 11, 12 corresponding to the spacing between the fitting grooves 16, 17 provided in the base body 2a, and the rear end edges of the two side walls are fitted into the fitting grooves from the upper end. Fitting portions 20 and 21 having lengths in the vertical direction are provided for attachment.

The bottom wall surface part 14 of this frame body consists of two parts 14a and 14b, front and rear, with different inclination directions, and the front part 14a is inclined backward and to the right, so that the stored balls are always directed to the right. At the same time as sending it, it falls toward the rear part 14b, and the other rear part 1
4b, the ball is tilted downward to the left toward the ball drop port 13 provided at the left end of the bottom wall surface.
It is designed so that it can be naturally guided.

The base body 2a and the frame body 2b are individually molded from plastic as shown in the figure, but here, the wall portion 7 of the base body 2a and its extension wall portion 7' are integrally molded, and the rectifying portion 8 and the bulb are molded together. The front wall portion of the supply gutter 9 is formed separately and screwed to the extension wall portion 7' when the detection step plate 18 and partition wall 19 are assembled to form a single base body.

The storage tank 2 of the present invention constructed as described above has a base 2a attached to the base frame plate 1 etc. when assembling a pachinko machine.
When the ball supply gutter 9 provided on the base body is fixed in advance and the ball supply gutter 9 provided on the base body is connected to the prize ball guiding path 22, the fitting portion 2 of the frame body is inserted into the fitting groove portions 16 and 17 provided on the base body.
0 and 21 facing from above and fitting the two bodies together and joining them together, the storage tank is completed.

In this case, the fitting groove parts 16, 17 and the fitting part 20,
21, the left and right side wall portions 1 of the frame body 2b
The rear edges of 1 and 12 and the rear edge of the bottom wall surface part 14 contact the front surface of the base frame and are integrated. A fitting piece 23 is provided on the rear edge of the base member 14, and a groove-shaped receiving portion 24 is provided on the front surface of the extended wall portion 7' of the base body for coupling.

In addition, when combining the base and the frame, the bottom wall 14 is always stepped down to provide a drop between the bottom of the recess 15 of the base and the bottom wall 14 of the frame, so that the ball of the recess 15 is It is designed to roll down to the frame side.
Furthermore, the bottom surface of the recessed portion 15 is connected to the bottom wall surface portion 14.
Like the rear portion 14b, it slopes downward to the left and toward the frame body, and a trapezoidal guiding protrusion 25 with a height close to the diameter of the sphere is provided at the left end.

In this way, the storage tank is attached to the frame 2 with respect to the base 2a.
b as described above, but by combining the frame 2b, the rectifying section 8 and the ball supply gutter 9, which have open upper surfaces, are simultaneously covered by the bottom wall surface 14. Therefore, the balls will not overflow from the rectifying section 8 and the supply gutter 9 during use.

The present invention is constructed as described above. First,
By separating the base and frame that make up the storage tank, it is possible to easily mold the main body of the tank, which has a complex shape, especially a complicated slope for guiding the flow of spheres, out of plastic. In addition, in the storage tank of the present invention, by inserting the fitting part of the frame body into the fitting groove part of the base body from above, the two bodies can be easily assembled to complete the storage tank.
Its handling is extremely simple.

Furthermore, in the storage tank of the present invention, the upper surfaces of the rectifying section 8 and the ball supply gutter 9 provided in the base are covered by the bottom wall of the removable frame, which may cause a failure in the detection step. Or, if dust has adhered to the inside of the ball supply gutter, removing the frame will make it extremely easy to repair the malfunction and remove the dust.
