[Effect of idea]

As is clear from the above explanation, the movable tatami floor according to the present invention can be assembled and disassembled by using the joint structure of members such as edge frames and by using only a minimum number of screw parts. It can be easily assembled when and where needed, and can be used as a tatami bed, floor, etc. Therefore, it is possible to easily create a Japanese-style room even in a Western-style house. In addition, the movable tatami floor can be disassembled and stored compactly when not needed.

Furthermore, according to the present invention, since there is a rod-shaped support leg extending in the across direction at the bottom of the framework,
Compared to a frame with vertical legs at the four corners, the part that is anchored to the ground is larger, so the center part of the frame does not fall down, and can be installed in a wide area. You can get a solid and stable tatami floor. In addition, since both ends of the base plate are fitted into grooves provided on the opposite edges of the frame body, the fixation between the base plate and the frame body is stable, and the base plate is used for placing tatami mats on top of it. The base plate does not drop even when the tatami is stretched, and the load is evenly distributed between the frame body and the rod-shaped support legs, thereby stably supporting the tatami. Furthermore, the supporting legs have the functions of both the legs of the framework body and the load receiving part of the tatami mat, and the number of other crossbars or joists can be reduced.
The number of component parts can be reduced, and materials can be saved accordingly, which also reduces costs.
