Among the toys using a conventional magnet, there was a toy that can manufacture a variety of structures using a magnet rod and a metal ball provided with a magnet. Briefly described as follows.

1 is an embodiment of a conventional metal ball and a magnet rod.

Magnetic rod 20 and the metal ball 10 is generally used is to invent to improve the intelligence development and creativity of children.

In the prior art configuration of the magnetic toy using such a magnetic material, as shown in Fig. 1, the outer surface of the magnet 21 on both ends is exposed in a state where the magnets 21 are attached to both ends of the metal rod 22. 23 is provided with a magnetic rod 20 covered with a magnetic rod, and is provided with a solid filling metal ball 10 made of a magnetic material attached by magnetic force.

The feature of this configuration is that the plurality of magnet poles 20 are connected in a radial direction with respect to the filling metal ball 10 to be connected at various angles as well as vertical and horizontal directions to form a colorful shape of the structure. .

However, in the prior art of the magnet toy using the above-described magnet, when a high height structure is made due to the weight occupied by the filling metal ball 10, a large load is applied to the lower end, and it is difficult to maintain the connection shape of the structure. Was present.

In addition, when the filling metal ball 10 is thrown, there is a problem that can hurt people or damage household appliances such as home appliances due to its own weight.

Conventional technology for solving the above problems existed to provide a hollow metal ball inside.

Figure 2 is a cross-sectional view of the manufacturing process of another conventional hollow metal ball.

As shown in the drawing, each press-contacting plate-side ball member 31, which is extended by a length L than the hollow ball diameter line, is pressed in an electrical manner to form a ball. A method of polishing and finishing has been attempted, and this technique has various problems as follows.

First, a strong heat or gas generated during the pressure contact is formed inside the ball, and the marking is not easily generated by the energy that tries to escape to the outside of the ball, but minute cracks and holes are generated.

In addition, if the projection A is removed from the A part like the B part through the polishing process, the hole for cracking becomes larger or larger.

When the plated pressure welding steel ball 30 produced in this process is plated, the plating liquid enters into finely formed cracks or holes and remains in the pressure welding steel ball 30.

Eventually, in the case of the press-bonded steel ball 30 finished in such a process, harmful plating solution flows out from the inside of the pressed-steel ball 30 during children's use, which may cause a fatal situation to the human body.

Second, because the electrical heat is generated strongly during the welding process, there is a problem in that the shape of the ball is changed to make a perfect sphere shape.

It is difficult to produce a certain quality product due to the difficulty of the set material, the press and the welding process, and the production cost is expensive.

Fifth, the immersion iron ball 30 is immersed in the plating solution during the plating process, there is a problem that the plating is very difficult to float on the plating solution due to buoyancy.

The present invention to solve the conventional problems as described above, relates to a metal ball that is easy to assemble, to provide a metal ball that can be attached to the metal ball to the magnetic rod at various angles and distances.

In addition, the present invention is to provide a metal ball that can be used in a structure that generates a lot of load, such as a high weight structure, such as a high weight, a large magnet rod or the like.

In another aspect, the present invention provides a metal ball having a simple assembly process, a structure that can be easily produced by the domestic industry.

In addition, the present invention provides a metal ball using connecting members such as chains, ropes, pipes, rods between the metal ball and the metal ball in representing a parabolic shape or a straight line.

And the present invention is to simplify the plating process of the metal ball, to provide a safe metal ball that the plating solution does not remain inside the metal ball.

The outer surface 42b is bonded to each other by bonding or other bonding means. At this time, the outer close end portion 41a and the inner close end portion 42a are brought into close contact with each other so as not to coincide with each other to complete the metal ball. When the inner ball and the outer half ball member 41 is bonded to each other by means of bonding means, surface tension is generated on the surface of the sphere so that it maintains a very tight adhesive force and is not separated from each other. Other joining means may use ultrasonic waves or high frequency, and the surface of the inner ball may be attached to the surface of the outer ball by applying heat to the assembled metal ball.

And as another method of forming the inner ball can be adopted by forcing the half-ball member to form a close contact with the concave-convex type.

At this time, the outer half ball member 41 may use a magnetic material such as iron or stainless steel containing iron metal, or may be made of a material that does not have a magnet such as synthetic resin and copper or aluminum, depending on the purpose of the metal ball. have.
