Abstract

(57) [Summary] [Purpose] To provide a slinging gutter for pachinko balls, which has a good flow of pachinko balls, is easy to manufacture, and is inexpensive. In a sending gutter 1 of a pachinko ball made of an aluminum alloy having a U-shaped cross section composed of both side walls 10, 10 and a bottom wall, the inner lower position is continuous with the upper surfaces of the bottom walls 11 of the both side walls 10, 10. Also, the fitting concave grooves 13, 13 are formed along the longitudinal direction of the both side walls 10, 10, and the fitting concave grooves 1 are formed.
It is characterized in that the flat stainless steel bottom plate 2 is fitted to the plates 3 and 13 so as to be superposed on the upper surface of the bottom wall.

[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention relates to a gutter for pachinko balls.

[0002]

[Prior Art]

 Conventionally, as is well known, in a pachinko game arcade, a plurality of pachinko machine installation islands 101 in which a large number of pachinko machines 100 are arranged side by side are installed as shown in FIG. The incoming balls are gathered by the gathering gutter 102 and are lifted to the upper island tank 104 by the polishing lift 103, and further supplied from the island tank 104 to the respective pachinko machines 100 via the sending trough 105 and the diversion chute 106. ing.

[0003]

[Problems to be solved by the device]

 By the way, most of the conventional troughs are formed by drawing aluminum. This aluminum gutter can be manufactured at a low cost because it is relatively easy to mold, but on the other hand, pachinko balls easily get dirty, and the gutter of the pachinko ball is a short time. There was a problem that the flow of was worse.

On the other hand, there is known a stainless steel transmission gutter to solve the above problems. However, there is a problem in that the stainless-steel gutter is difficult to bend and the manufacturing cost is very high. The present invention has been made in view of the above problems of the prior art, and an object of the present invention is to provide a pachinko ball that slides smoothly, is easy to manufacture, and is inexpensive. It is intended to provide gutters.

In order to achieve the above object, the present invention is a casting gutter of an aluminum alloy pachinko ball having a U-shaped cross-section formed by both side walls and a bottom wall. At the inner lower position, the fitting concave grooves are formed along the longitudinal direction of both side walls, and the flat stainless steel bottom plate is fitted into the fitting concave grooves so that they are superposed on the upper surface of the bottom wall. It was done.

[0006]

[Action]

 The pachinko ball sluice gutter constructed as described above is easy and inexpensive to manufacture, because a flat stainless steel bottom plate is simply placed on the upper surface of the bottom gutter of the sluice gutter by aluminum drawing. Can be provided to. The stainless steel bottom plate, which is superposed on the upper surface of the bottom wall of the gutter, prevents the dirt from adhering to the pachinko balls and improves the flow of the pachinko balls.

【Example】

 An embodiment of the present invention will be described below with reference to the drawings. FIG. 1 is a perspective view of a flow gutter according to the present invention, FIG. 2 is an exploded perspective view thereof, and FIG. 3 is a cross sectional view thereof. In the figure, 1 is a sending trough, and 2 is a stainless steel bottom plate. The sending trough 1 is formed by drawing aluminum and has a substantially U-shaped cross section having both side walls 10 and 10 and a bottom wall 11. More specifically, the side walls 10, 10 are formed with a diversion port 12 corresponding to each pachinko machine, and the side walls 10, 10 are extended below the bottom wall 11 to form mounting portions 10a, 10a. Has been formed. Further, the bottom wall 11 is slightly curved in an arch shape so that both side portions are lowered.

On the other hand, at the inner lower position connected to the upper surface of the bottom wall 11 of both side walls 10, 10 of the sending trough 1, a fitting for fitting the stainless steel bottom plate 2 along the longitudinal direction of the both side walls 10, 10. Fitting grooves 13, 13 are provided.

The stainless steel bottom plate 2 has a flat plate shape having the same length as the sending gutter 1 and a width in a lateral direction thereof slightly larger than a lateral width of the sending gutter 1, and both side edges thereof are provided. It is to be fitted into the fitting concave grooves 13, 13 from the side of 1, and the stainless bottom plate 2 is superposed on the upper surface of the bottom wall 11 of the sending gutter 1 to form an integral structure.

[0010]

EFFECTS OF THE INVENTION Since the present invention is configured as described above, it has the following effects. By placing the stainless steel bottom plate on the upper surface of the bottom wall of the gutter, it is possible to prevent dirt from attaching to the pachinko balls and improve the flow of the pachinko balls.

Further, since the stainless steel bottom plate is simply a flat plate, it is not necessary to perform a difficult bending process, and the shunt trough can be reduced in cost.

Further, in order to superimpose the stainless bottom plate on the upper surface of the bottom wall of the sending gutter, fitting recessed grooves are formed at the inner lower positions of both side walls of the sending gutter and along the longitudinal direction of both side walls thereof. By adopting a configuration in which a flat plate-shaped stainless steel bottom plate is fitted into this fitting groove, the stainless steel bottom plate can be securely attached to the upper surface of the bottom wall of the sending trough by simple work. In addition, if the stainless steel bottom plate becomes dirty, it can be easily removed from the trough and washed with water or wiped clean.

[0013] Furthermore, since the sling of the pachinko balls is improved by the stainless steel bottom plate, it is possible to make the slant of the gutter more gentle, which makes the pachinko machine installation island longer and pachinko machine. Can be installed in large numbers.
