Description

[Detailed Description of the Invention] (Industrial field of application) The present invention relates to a connecting fitting of different diameter bellows used for connecting bellows in a ball path for supplying balls to a pachinko ball lending machine or a pachinko machine. .

(Prior art) Connection of different diameter bellows in a ball passage that supplies pachinko balls to a pachinko ball lending machine or a pachinko machine via a split gutter, simply insert a thick bellows into a thin bellows connection part. By connecting.

(Problems to be solved by the invention) According to the conventional device as described above, since the thick bellows cannot be inserted deeply into the thin bellows at the connection portion, the connection portion is detached due to ball pressure or the like and the ball supply to the pachinko ball lending machine or the like is performed. The above trouble had occurred.

In addition, Japanese Utility Model Publication No. 47-38135 discloses a coupling tool for a coil spring-shaped tubular gutter and a hard tubular gutter, but the coil spring-shaped tubular gutter is fixed to a tubular frame fixed to a plate and has a different diameter. It is not a connecting fitting between bellows.

Therefore, the object of the present invention is to obtain a connecting fitting of different diameter bellows in which no trouble occurs in the different diameter bellows connecting portion.

(Means for Solving the Problem) In order to achieve the above objects, the connection fitting of the present invention is configured as follows.

That is, an elongated hooking piece is formed on one of the bendable thin plate-like main bodies that can be wound around the outer periphery of the connection portion of the bellows, and an insertion hole for the hooking piece is formed in the main body. The individual locking claws are formed so as to be press fit between the adjacent spring wires of the bellows, and the locking claws have a height that does not project into the bellows during press fitting.

(Operation) The connection tool of the present invention is such that a thin plate-shaped body is wound around the outer periphery of the connection portion of the thin bellows and the thick bellows, and the locking claws are press-fitted between the adjacent spring wires of the bellows to connect the bellows to each other, and the hooking piece is attached. Put it in the insertion hole of the main body and fold it back to fix the fitting to the bellows.

(Example) An example shown in the drawings will be described below.

(1) is a ball lending machine, which has a thin metal fitting (2) for bellows forming a ball passage.

The connection portion of the thin bellows (3) is formed in a size into which the thick bellows (4) can be inserted.

(5) is a supply gutter connected to a supply tank. There is a shunt gutter (6), a thick bellows (4) is connected to this shunt gutter (6), and a pachinko ball is a supply gutter (5) and a shunt gutter (6). ), Then through the thick bellows (4) to the thin bellows (3)
From the ball lending machine (1).

The present proposal uses connecting fittings so that the connecting portions of the bellows (4) and (3) as described above do not come off.

The connecting metal fitting (7) has an elongated hooking piece (9) formed on one side of a bendable thin plate-like body (8), and a hole (10) through which the hooking piece (9) can be inserted is formed in the body (8). Has been formed.

A plurality of locking claws (11) are vertically bent to form a plurality of protrusions on both left and right edges of the main body (8).

The height of this locking claw (11) is such that it does not project into the thick bellows, and it is press-fitted between the spring wires of the thick bellows (4) and the thin bellows (3) so that the bellows can be connected to each other. I shall.

The locking claws are formed by bending both edges as shown in the figure.
It may be formed only on one edge or may be cut out from the main body. The shape is free and the point is to use a locking claw that connects the bellows.

In the connection fitting as described above, the main body (8) is wound around the outer periphery of the connection portion and the locking claw (11) is provided with the bellows (3) as shown in FIG.
It is press-fitted laterally between the spring wires of (4) to prevent the bellows (3) and (4) from shifting up and down, and the hooking piece (9) is inserted from the inside of the hole (10) and folded. By bending, the main body is fixed to the outer periphery of the bellows (3)
The lateral displacement of (4) is also prevented.

To remove the connection fitting (7) from the connection part, remove the hooking piece (9) from the hole (10), spread the wound body (8), and pull the locking claw (11) outward from between the spring wires. The connection fitting can be easily removed by pulling it toward.

In addition, in the present embodiment, an example in which the present invention is used for a pachinko ball lending machine has been described, but it can be similarly used for a pachinko machine, which is not shown in the drawing.

(Effect of the Invention) In the case of the present invention, since the locking claws are press-fitted between the spring wires of the bellows, the bellows are connected and never come off.

Therefore, even if a ball pressure is applied to the connecting portion of the different diameter bellows, the bellows cannot be easily disengaged, and the joint becomes reliable, and troubles in ball supply to a pachinko ball lending machine, a pachinko machine, etc. can be eliminated. Also, when the pachinko ball lending machine or pachinko machine is replaced, this joint fitting can be used for joints of different diameter bellows for easy installation and removal.

However, since the height of the locking claw is formed so as not to project into the bellows, the flow of the pachinko balls is not obstructed by this, and it can be freely removed and used for connecting the bellows to each other at other locations. There is a feature called.
