Description
BACKGROUND

1. Technical Field

The technical field relates to a training device, more particularly to an assembly-type balance training device.

2. Related Art

Since children's body and brain are developing, using proper environment and device for training can be benefit to the children's development.

The common training device seldom trains the sense of balance of children. Therefore, children can only teach themselves slowly in the surrounding environment. However, safe can be guaranteed in surrounding environment, where children are easily got injured. Therefore, balance beam is created.

Nowadays, the balance beam can be classified as follows:

1. Integrally formed balance beam. This kind of balance beam is bulky, so even though it is more stable in using compared to others, the storage and transportation of the integrally formed balance beam are still inconvenient.

2. Multiple small pieces of balance beam placed side by side or separately on the ground for children walking thereon to train the sense of balance. However, since each of the balance beams are separately placed, the single unit of the balance beams is light weighted and easy to be disengaged with other pieces of balance beam, which causes danger to the user due to the instability.

3. Bridges are provided among small pieces of balance beam for children being trained sense of balance thereon. However, the connection between the bridges and the balance beam units is unstable, even more, simply placing the bridges on the balance beam units, which is very dangerous to children to walk on the extremely unstable bridges.

Therefore, it is very important for the present invention to provide an easy assemble/disassemble balance beam structure. After the single balance beam units are assembled, a very stable balance training device is obtained, while each single balance beam is small in volume and easy to store and transport after the balance training device being disassembled.
