<P>PROBLEM TO BE SOLVED: To provide an angle controllable freely curved ruler which can be freely bent and fixed, and can easily be recovered to an original curved shape even after deformed. <P>SOLUTION: In the angle controllable freely curved ruler, a core in which joint parts (3), a joint part end 1(2) and a joint part end 2(4) are connected is inserted to a ruler part (1), and gears (7) and elastic members (5) such as coil springs are used in a portion where they are connected. Fixing units (6) are inserted for fixing between the gears (7) and the joint part (3) and between the gears (7) and the joint parts end 2(4), and joint shafts (8) are inserted for connecting between the joint part (3) and another joint part (3), between the joint part (3) and the joint part end 1(2), and between the joint part (3) and the joint part end 2(4), respectively. <P>COPYRIGHT: (C)2013,JPO&INPIT |
