<p>PURPOSE:To subject the link device entirely to zigzag deformation by connecting link units to each other in the vertical direction in series and piling up deformation actions of respective link units. CONSTITUTION:The single body of a link unit is based on a regular tetragonal pillars. At positions corresponding to four ridge lines of the sides of the regular tetragonal pillars, respective actuators 2, 3, 4 and 5 are disposed. At positions corresponding to upper four ridgeline and lower four ridgelines, are disposed rectangular frame lines 6 and 7. At positions corresponding to a diagonal line connecting the front side surface and the rear side surface shown in the drawing of four side surfaces of the regular tetragonal pillar, are disposed interrossing links 8 and 9. These link units are connected vertically and actuators are expanded and contracted by oil pressure, whereby the link mechanism can be deformed in zigzag manner.</p> |
