SMART STAIRS WITH A VARYING SLOPE

摘要

The present invention relates to smart stairs having a varying slope, which comprise: a tread-board having a protruding shaft on both ends of a longitudinal direction; a support member arranged in both portions of a longitudinal direction of the tread-board to be rotationally mounted around the shaft; an angle adjusting member having a predetermined length and arranged in a side of the support member, wherein an end portion is fixated with the shaft; and an angle conversion device installed to induce shaft rotation of the angle adjusting member by shuttling a free end portion of the angle adjusting member around a coupling portion with the shaft, thereby being converted to stairs or a slope with simple operation and sufficiently supporting a large downward force.
