In the conventional example shown in FIG. 2, the configuration of the riser plate is different.
No reinforcement is provided. That is, the riser disposed below the step board 57 is divided at the corner A, and one riser 1 is made thicker than the other riser 2. In addition, a fitting portion 3 in which the side edge portion of the other riser plate 2 on the corner portion A side is recessed is formed at the side edge of the back surface of one riser plate 1 on the corner portion A side. In this case, the fitting portion 3 is a V-shaped groove formed by cutting out a corner between the side end surface of the one riser plate 1 on the corner A side and the back surface. Further, the pair of riser plates 1 and 2 are formed of a plate material and a solid material. Other configurations are the same as the conventional example.

荷重を負担でき、補強材は不要となる。In this embodiment, the corner portion A is formed simply by fitting the side edge of the other riser plate 2 on the corner A side into the accommodation portion 3 of the one riser plate 1. For this reason, the configuration is simplified and the assembling workability is improved. Further, in a state where the side edge of the other riser plate 2 is accommodated in the accommodation portion 3 of the one riser plate 1, both the riser plates 1 and 2 are rotatable.
The corner A can be easily set at a predetermined angle. As described above, since the angle of the corner portion A is determined by rotating the riser plates 1 and 2, the angle can be easily changed, the variation can be developed, and the design can be diversified. in this case,
The fitting portion 3 is a V-shaped groove formed by cutting out a corner between the side end surface of the one riser 1 on the corner A side and the back surface. Wider and more diverse in design. Further, since one riser plate 1 is made thicker than the other riser plate 2, the load applied to the tread plate 57 can be borne, and a reinforcing material is not required.

第１の実施例の同様である。FIG. 3 shows a second embodiment. In this embodiment, the receiving portion 4 has a groove shape. Numeral 5 is rubber or soft plastic. One side is bonded to one riser 1 and the other side is pressed against the other riser 2 to conceal the gap between the risers 1 and 2. Other configurations are the same as those of the first embodiment. In this embodiment, it is possible to prevent the side edge portion of the other riser plate 2 from coming off from the receiving portion 4 of the one riser plate 1 to the outside. Note that the rotatable angle of the other riser plate 2 is smaller than in the first embodiment. Other effects are the same as those of the first embodiment.

る。According to the staircase of the first aspect, the corner portion is formed only by fitting the side edge of the other riser plate on the corner side into the accommodation portion of the one riser plate. For this reason, the configuration is simplified and the assembling workability is improved. Further, since the two risers are rotatable in a state where the side edges of the other riser are accommodated in the accommodation portions of the one riser, the corners can be easily set at a predetermined angle. As described above, since the angle of the corner portion is determined by rotating the riser plate, the angle can be easily changed, the variation can be developed, and the design can be diversified. Further, since one riser is made thicker than the other riser, it is possible to bear the load applied to the tread.
