Description

[Detailed Description of the Invention] [Industrial field of application] The present invention is to hold a bellows pipe for replenishing a prize ball tank ball of each pachinko machine from a replenishment trough arranged above a pachinko machine installation island. It is about ingredients.

[Conventional technology]

Conventionally, in a pachinko game hall, a supply gutter arranged above the pachinko machine installation island and a ball counting supply device provided above the prize ball tank of each pachinko machine are connected by a bellows pipe to form a supply gutter. The pachinko ball flowing down is supplied to the prize ball tank through the bellows pipe and the counting supply device.

[Problems to be solved by the device]

By the way, if the drop between the supply gutter and the prize ball tank is large, the ball pressure of the pachinko ball in the bellows pipe will increase and a large load will be placed on the solenoid etc. of the ball counting and replenishing device, causing trouble in operation and smooth replenishment. There was a problem that it could not be done. On the other hand, in order to solve the above-mentioned problems, at present, as shown in, for example, Japanese Utility Model Publication No. 40-32915, a bellows pipe is bent through a ring portion of a mounting bracket, and thereby a ball pressure is controlled. Seems to be used.

However, the above method does not cause a problem when the head between the supply trough and the prize ball tank is small, but when the head becomes large, it is not very useful, and a solution is strongly desired. It was In particular, the drop between the supply gutter and the prize ball tank is different for each pachinko game hall, and it was very difficult to satisfy all of these ball pressure controls.

The present invention has been made in view of the above problems of the prior art, and enables the bellows pipe to be freely bent and held by a simple operation so that the drop between the supply trough and the prize ball tank is reduced. It is an object of the present invention to provide a holder for a bellows pipe for pachinko ball replenishment, in which the ball pressure can be easily controlled according to the above.

[Means for Solving the Problems]

In order to achieve such an object, the holder of the bellows pipe of the present invention has a tubular portion into which the lower end of the bellows pipe is inserted, and the movable arm is flexibly connected downward to a fixed arm protruding laterally from the tubular portion. Further, ring rings for inserting the bellows pipes are rotatably attached to the upper surfaces of the fixed arm and the movable arm, respectively.

[Action]

The bellows pipe is inserted into both or either of the ring attached to the upper surface of the fixed arm and the movable arm in the forward direction or the reverse direction, and then the lower end is inserted into the tubular portion to be fixed. As a result, the bellows pipe is supported in a bent state or in a state in which the bellows pipe is circulated so as to draw a ring, and it is possible to control the ball pressure according to the drop by the degree of bending.

〔Example〕

An embodiment of the present invention will be described below with reference to the drawings. FIG. 1 is a partial front view of a pachinko machine installation island, and FIG. 2 is a partial perspective view of a pachinko machine installation island. In the figure, 1 is a pachinko machine installation island, 2 is a pachinko machine installation island, 3 is a supply gutter disposed above the pachinko machine installation island 1, 4 is a supply gutter 3 corresponding to the prize ball tank 5 of each pachinko machine 2. The diversion gutters 6 attached to the side surfaces are bellows pipes whose upper ends are connected to the ball outlets 7 of the diversion gutters 4. Reference numeral 8 is a ball counting and replenishing device mounted above the prize ball tank 5, and the lower end of the bellows pipe 6 is connected to the ball inlet 9 of the prize ball tank 5 via the holder 10 according to the present invention. 11 is a supply ball detector.

FIG. 3 is a perspective view of the holder 10, and FIG. 4 is a cross-sectional view of an essential part showing a mounting state of the holder 10. The holder 10 has a cylindrical portion 12 into which the lower end of the bellows pipe 6 is inserted, a fixed arm 13 is integrally formed on the side surface of the cylindrical portion 12 in a horizontal horizontal direction, and a movable arm is provided at the tip of the fixed arm 13. A screw shaft 15 is pivotally connected to the screw shaft 15.

The tubular portion 12 and the fixed arm 13 are formed as a half body which is divided into two parts at the center, and they are integrated by tightening a screw 16. In addition, the tube part 12
A plurality of anti-slip ridges 17 are circumferentially provided on the inner peripheral surface of, and a flange 18 is formed at the lower end thereof so as to protrude in the outer peripheral direction. The movable arm 14 is formed in a bow shape in which the entire movable arm 14 is curved upward in an arc shape, and can be bent and rotated downward in a range of about 90 degrees.

Rings 19 and 20 through which the bellows pipe 6 is inserted are attached to the upper surfaces of the fixed arm 13 and the movable arm 14 at positions near the tips thereof so as to be rotatable in the arm direction.

As shown in FIG. 4, the holder 10 thus constructed superposes the flange 18 of the cylindrical portion 12 on the flange 9a formed at the ball inlet 9 of the ball counting and replenishing device 8 to form both flanges 9a and 18a. Install by tightening with the tightening ring 21. The tube
When the bellows pipe 6 is connected to 12, the screw 16 is loosened, the lower end of the bellows pipe 6 is inserted into the tubular portion 12, and then the loosened screw 16 is tightened. As a result, the bellows pipe 6 is firmly fixed and held in the tubular portion 12.

5 to 10 show how the holder 10 is used. That is, if the drop between the supply trough 3 and the prize ball tank 5 is about 10 cm, it is not necessary to bend the bellows pipe 6 through the annular rings 19 and 20, and the state shown in FIG. 5 may be used.

If the drop is about 10 to 15 cm, the lower part of the bellows pipe 6 is inserted only into the ring 19 provided on the fixed arm 13 as shown in FIG. 6, and the ring 19 is rotated slightly to the left. Support it in an S-shape with an extremely gentle curve.

If the head is about 15 to 20 cm, the lower part of the bellows pipe 6 is inserted into both the ring rings 19 and 20, as shown in FIG.
At the same time, the annuluses 19 and 20 are rotated to the left side, respectively, so that the annuluses are supported in an S-shape which is bent in a curve stronger than in FIG.

If the head is about 20 to 25 cm, as shown in FIG. 8, the lower part of the bellows pipe 6 is inserted only in the annular ring 19 in the reverse direction of the state shown in FIGS. 6 and 7, and Turn 19 to the right to support it in a twisted shape. The movable arm
The ring 14 and the ring 20 are lowered downward so as not to hinder the bending of the bellows pipe 6.

If the drop is about 25 to 30 cm, as shown in FIG. 9, the lower part of the bellows pipe 6 is inserted only in the annulus 20 in the opposite direction, and the annulus 20 is rotated to the left side to make the bellows pipe. Make the lower part of 6 circulate so as to draw a ring and support it.

Further, when the head is more than 30 cm, the lower part of the bellows pipe 6 is inserted into both of the rings 19 and 20 in opposite directions as shown in FIG. 10, and the ring is drawn as in the case of FIG. Bend to. In this case, the bent portion is also firmly supported by the ring 19 and can be supported more firmly than in FIG.

[Effect of device]

As described above, according to the present invention, the bellows pipe for pachinko ball replenishment can be bent and held in various modes by a simple operation, depending on the drop between the replenishment gutter and the prize ball tank of the pachinko machine. The ball pressure can be controlled in an optimum state.
