Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a game ball supply device for a ball game machine such as an arrangement ball machine or a pachinko machine.

[0002]

2. Description of the Related Art Conventionally, as a game ball supply device for a ball game machine, there is one disclosed in Japanese Patent Publication No. 55-13747. In this game ball supply device, the base side of an operating rod made of a metal wire is fixed to a hammer, and a coil is formed at an engaging portion formed on the tip side of the operating rod so as to be bent corresponding to the operating member of the ball feeding means. The spring is rotatably fitted, and along with the operation of the hammer, the operating member is operated by the operating rod via the coil spring of the engaging part, and the game ball is supplied from the ball feeding means to the launch position on the launch rail. I am trying to do it.

The operating rod is bent at a tip end side of its main body portion in a direction substantially perpendicular to the main body portion to form an engaging portion, and the engaging portion is formed on the side opposite to the main body portion side. Bending the end portion side of the portion at substantially right angles in the same direction as the bending direction of the main body portion to form a retaining portion having a length substantially the same as the length of the engaging portion,
The main body side of the operating rod, the engaging portion, and the retaining portion are substantially U-shaped.
It is configured to have a letter shape.

[0004]

In this type of game ball supply device, in order to mount the coil spring on the engaging portion of the operating rod, first, the coil spring is externally fitted to the retaining portion,
A method is adopted in which the coil spring is pushed into the engaging portion side while curving from the retaining portion side through the corner portion.

However, in the conventional operating rod, the retaining portion is bent with respect to the engaging portion in the same direction as the bending direction of the main body portion, and the three portions of the main body portion, the engaging portion and the retaining portion are U-shaped. Since the coil spring is bent so as to have a shape, the work for mounting the coil spring on the engaging portion is very troublesome, and the operating rod may be deformed when the coil spring is mounted.

That is, when the coil spring is attached to the engaging portion, first, the main body portion side of the operating rod is grasped by one hand, and the coil spring is held by the other hand and the coil spring is attached to the retaining portion side. Fit the spring over. Then, the coil spring fitted on the retaining portion is pushed toward the engaging portion side while being curved along the corner between the engaging portion and the retaining portion.

In this case, when the tip end side of the coil spring passes through the corner between the engaging portion and the retaining portion, a very large pushing force is required. The retaining part is in the same direction, the lengths of the coil spring and retaining part are almost the same, and the coil spring is completely fitted to the rear end side of the coil spring. Since it is not possible to push the coil spring into the engaging portion side while the rear end side is pressed against another fixed object such as a workbench, mounting of the coil spring is extremely difficult and complicated.

If the coil spring is forced in, the operating rod may be bent and deformed on the tip side of the main body. Therefore, it is necessary to use a material having a large wire diameter for the operating rod. Further, in the conventional operating rod, the shape of the splicing portion that splices on the side surface of the striking mallet is straight in a side view on the base side of the main body through an oblique bending portion that is bent in an oblique direction opposite to the engaging portion. Since a ring-shaped screw insertion portion is formed at the end of the splicing portion, and the operating rod is fixed to the hammer by inserting a screw into the screw insertion portion, Even if the base side of the operating rod is gripped with a finger when the coil spring is attached, if the force is applied to the coil spring on the retaining portion side, the operating rod is likely to rotate around the axis of the main body side.

Further, even when the operating rod is fixed to the side surface of the striking mallet, the shape of the main body portion and the splicing portion in a side view is substantially straight when the distance between the screw and the engaging portion is constant. Therefore, the length of the splicing portion in which the actuating rod abuts the side surface of the striking mallet becomes short, and the length of the main body portion becomes long, so that the amount of protrusion from the striking mallet becomes large. Therefore, if the wire diameter of the operating rod is made thin, there is a drawback that the stability of the operating rod on the engaging portion side becomes poor.

In view of such conventional problems, the present invention makes it possible to easily attach the coil spring to the engaging portion of the operating rod, prevent deformation of the operating rod, and further, to increase the wire diameter of the operating rod. It is an object of the present invention to provide a game ball supply device for a ball game machine that can ensure the stability of the engaging portion even if the thickness is reduced.

While holding the portion 43 side, the one end portion side of the elastic body 44 is fitted over the retaining portion 40 side. Then, when the other end side of the elastic body 44 is pressed against the fixed side such as the workbench, the elastic body 44 passes through the corner portion of the engaging portion 39 and the retaining portion 40 while passing through the corner portion. Then, it is fitted on the side of the engaging portion 39.

If the other end of the elastic body 44 coincides with the end of the retaining portion 40, then the elastic body 44 may be gripped and pushed into the engaging portion 39 side. At this time, since one end side of the elastic body 44 has passed through the corner portion, the elastic body 44 is easily curved while being bent.
