Description

[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention relates to a gutter for pachinko balls.

[0002]

[Prior Art]

 As is well known, in a pachinko game arcade, as shown in FIG. 4, a plurality of pachinko machine installation islands 101 in which a large number of pachinko machines 100 are arranged side by side are installed and discharged from each pachinko machine 100. The 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 gutter 105 and the diversion gutter 106. ing.

[0003]

[Problems to be solved by the device]

 By the way, most of the conventional pachinko ball flow gutters 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 gushing surface causes the gutter to move in a short time. There was a problem that the flow became poor.

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 that a pachinko ball slides well, and the manufacturing cost is easy and inexpensive. It is intended to provide a gutter for pachinko balls.

[0006]

[Means for Solving the Problems]

 In order to achieve the above-mentioned object, the present invention provides a pachinko ball flow trough formed by a side wall and a bottom wall with a U-shaped cross section, wherein the side wall and the bottom wall are separately formed. On both sides of the bottom wall, sandwiching grooves are formed along the length direction, and a flat plate-shaped stainless steel bottom plate is superposed on the upper surface, and the inner bottom of each side wall is pressed along the length direction. A piece is provided, the lower ends of the both side walls are fitted into the sandwiching grooves of the bottom wall to be integrated with each other, and the holding pieces of the both side walls are brought into contact with the stainless steel bottom plate and pressed from above.

[0007]

[Action]

 The slinging gutter of a pachinko ball configured as described above is constructed such that a flat plate-shaped stainless bottom plate is superposed on the upper surface of the bottom wall and the lower ends of both side walls formed separately from the bottom wall are sandwiched between the bottom wall. Since the stainless bottom plate can be easily overlaid on the upper surface of the bottom wall because it only fits into the insertion groove and is integrated, it is easy and inexpensive to manufacture the sending gutter having the stainless bottom plate. .

The stainless steel bottom plate superposed on the upper surface of the bottom wall prevents dirt from adhering to the pachinko balls and improves the flow (sliding) of the pachinko balls.

[0009]

【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, reference numeral 1 is a sending trough having a U-shaped cross section, in which a bottom wall 2 and left and right side walls 3, 3 are separately formed by aluminum drawing. Reference numeral 4 is a flat stainless bottom plate.

The bottom wall 2 has interposing grooves 5 and 5 having an upper surface opening continuously on both sides thereof in the longitudinal direction. The sandwiching grooves 5 and 5 have a vertical U-shaped cross-section, and one inner surface of the inserting grooves 5 and 5 has a corrugated locking portion 6 for the purpose of securely attaching the side walls 3 and 3 to the bottom wall 2. , 6 are provided. In addition, the upper surface of the bottom wall 2 is slightly curved in an arch shape so that both sides are lowered.

The left and right side walls 3, 3 are plate-shaped, and the inner and lower ends of the side walls 3, 3 are engaged with the engaging portions 6, 6 of the bottom wall 2 and have a corrugated engaged portion 7, 7 are provided respectively. Further, strip-shaped pressing pieces 8, 8 are continuously provided in the longitudinal direction on the inner lower portions of the left and right side walls 3, 3 in order to press the stainless bottom plate 4 superposed on the upper surface of the bottom wall 2 from above. Has been. Further, the left and right side walls 3, 3 are formed with cutouts 9 corresponding to each pachinko machine.

In the gutter 1 of the present embodiment configured as described above, the stainless bottom plate 4 is superposed on the upper surface of the bottom wall 2 in advance, and then the lower ends of the left and right side walls 3, 3 are bottomed. The engaging portions 6, 6 and the engaged portions 7, 7 are engaged with each other by fitting in the sandwiching grooves 5, 5 of the wall 2. As a result, the bottom wall 2 and the side walls 3 and 3 are integrated with each other, and the pressing pieces 8 and 8 are brought into contact with the upper surfaces of both side end portions of the stainless steel bottom plate 4 and pressed from above.

[0013]

[Effect of the device]

 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 flat plate-shaped, it is not necessary to perform a difficult bending process, and accordingly, the flow trough can be reduced in cost.

In addition, the bottom wall and the left and right side walls of the sending trough are formed separately, and the lower ends of both side walls are fitted into the sandwiching grooves of the bottom wall to be integrated with each other. By adopting a configuration in which the stainless bottom plate is pressed from above by the presser piece provided on the, it is possible to easily and surely attach the stainless bottom plate to the upper surface of the bottom wall of the sending gutter without seeing an increase in the number of assembling steps of the sending gutter. In addition, even if any notch processing such as forming a shunt on the side wall is not affected by burrs etc. due to the notch processing at all, it does not hinder the mounting of the stainless bottom plate. Absent.

Further, since the stainless steel bottom plate allows the pachinko balls to flow smoothly, it is possible to make the installation gradient of the gutter looser, which makes the pachinko machine installation island longer and pachinko machine. It is possible to increase the number of installed.
