It is arranged so that the bottom of a front structural member 2c can be coupled with the corresponding rear structural member 2d and also, that the bottoms of the rear structural member 2d and a reinforcing piece 2e can be coupled with differently tall support legs C1-C2 and waist frames C3-C5, respectively.

Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a temporary sash seat for watching sumo wrestling, which is installed on the floor of a gymnasium, multi-purpose hall or the like.

[0002]

[Problems to be Solved by the Invention] In sumo wrestling places, local gymnasiums or multipurpose halls are used as venues. In this case, the spectator seats often consist of tatami mats and planks simply laid out around the rings formed in the center of these floors, making it difficult to watch from the back row seats far away from the rings.

On the other hand, it is almost impossible in time, scale, and cost to assemble a full-scale staircase-like seating seat used at this place in a venue of a local touring place for only a few days. Met.

The present invention has been made to solve the above problems, and an object of the present invention is to provide a full-scale, step-like sumo wagon seat for seating that can be assembled easily and quickly.

[0005]

Means for Solving the Problems The present invention which achieves the above object is a sill seat which is installed around the ring in a staircase shape which becomes higher toward the rear stage. And a rectangular supporting board which is long in the front-rear direction and is formed by combining the supporting board pieces, and a rectangular supporting frame for supporting the long side portion of the supporting board on the floor surface. Further, the rectangular support frame is formed in a rectangular cross section in which the horizontal upper chord member can support the long side portion of the above-mentioned slab along with the long side portions of other adjacent slabs. In addition, the lower end of the vertical building material at the front portion and the upper end of the vertical building material at the rear portion are formed to be connectable via a connecting pin. Further, the lower end of the vertical reinforcing building material located at the center between the front and rear building materials and the lower end of the rear building material can be connected to supporting legs or waist frames having different heights via connecting pins. Is formed in.
