PARALLEL MOVING CANTILEVER COLUMN BEAM

摘要

PURPOSE:To obtain such a beam that part of a column beam moves in parallel by providing the 1st beam which is formed with the 1st slit and fixed at one end to a base substantially and a block-shaped moving part to which a peripheral part is connected across the 2nd slit. CONSTITUTION:A column beam 2 is welded 11 fixedly to the base 1 at one end and free at the other end and the 1st slit 21 is provided to the column beam 2; and the 1st beam 22 is formed into the column beam 2 with the slit 21 and one end is fixed to the base 1 substantially. The 2nd and the 3rd beams 23 and 24 are formed into column beams 2 with the slit 21 and provided in parallel across the 1st beam 22 while the gap of the slit 21 is maintained. The block-shaped moving part 26 to which the peripheral edge part 251 of a discoid connecting part 25 is connected across the 2nd slit 27 is provided at the peripheral edge part 251. When a linear input Fin is applied to a moving part 26 externally, the 1st beam 22 and connecting part 25 deform respectively and the moving part 26 moves by delta in parallel in proportion to the spring constant of the 1st beam 22 and connecting part 25.
