<p>PROBLEM TO BE SOLVED: To provide a platform which eliminates rickety legs and enables the user to safely step up and step down. SOLUTION: There is provided a platform comprised of a stand portion 2 and leg members 3 supporting the same. The stand portion 2 has a rear surface in which a plurality of rectangular grooves 6 are concavely formed, and the leg members 3 are each formed of an upper side portion 3A and leg portions 3B obtained by bending both ends of the upper side portion 3A. The leg member 3 is of a prismatic shape and at least the upper side portion 3A is nearly suitably fitted into the rectangular groove 6 in the rear surface of the stand portion 2. Thus, the upper side portions 3A of the leg members 3 are suitably fitted into the respective rectangular grooves 6 in the stand portion 2 to be fixed thereto, to thereby construct the platform. In this construction, faltering of the leg members 3 can be prevented by virtue of key effect.</p> |
