Description

TUBE-CONNECTING TYPE TOY

BACKGROUND OF THE INVENTION

Field of the Invention

The present invention relates to assembly toys, more particularly, to provide in many different forms, such as block, magnetic bar and wood.

Description of the Related Art

Generally, assembly toys are provided in many different forms, such as block, magnetic bar and wood. The representative block toy is LEGO. In LEGO, there are connection projection and connection groove, so it can be assembled without any special connection. But, when it is manufactured by using the tube, the connector that connects the tubes is highly needed.

The connecting means used at the tube assembly form many connection ribs, so it makes the tube be connected, and is providing only specific equal angle such as linear or cruciform type to ease the connection with many tubes.

The forms stated above are fixed in angles, so they are useable only to the parts fitting to each forms, and when the connection angles are different, the connecting means are needed which have special angles. Also, by making the angles that connection ribs form by overlapping the linear form and cruciform by plural number, the method that controls connection angle between the tubes are being used. But as we see the above statements, due to the thickness of the connecting bar, the connection rib is not located on the same plane, so it is hard to form a specific angle.

SUMMARY OF THE INVENTION

This invention is for the tube connector for assembly toy. Stating in more detail, it constructs the connector to cross each other. To the parts that intersect, it forms a groove part, so it makes their thickness partially overlapped, and locates the connection rib of other connectors to the identical surface. As a result, it can verify the forming angles of connection rib by which the tube is connected.

Therefore, the present invention has been made in view of the above the problem.

It is partially overlapped by the groove part when it is cross-connected by other connector while forming the groove part at the center of the body. So, the protruded connection ribs to the body are on the identical plane.

Another form of connector is composed of body and connection rib of the connector, which are separated. There are grooves that can insert connection rib or tube alongside the body. The groove is of semicircle form. When connecting the two bodies facing each other, the connection rib of each body is on the plane, so the angles among the connection rib can be various in types.
