There is a problem in the basic structure that the body is pressed against the floor surface and the rotation of the column is heavy, and even if the grounding body is provided with casters, the folding work is very difficult. In addition, if the structure is such that the front part of the top plate is lifted and folded, the strut is vertically erected at the rear part of the grounding body. Become stable. Also, the top plate rotates about 90 degrees,
Since the column rotates about 45 °, the rotation of the top plate and the rotation of the column are not completely interlocked, and there is a play of approximately 45 ° before the cam and the projection engage, and the operation is discontinuous. is there. Furthermore,
Since the rear part of the top plate is pivotally attached to the curtain plate between both columns, a bendable support rod between the support cylinder of the column and the front part of the top plate is needed to maintain the top plate in a stable horizontal state. Must be provided.
