Multi-degree-of-freedom adjustment mechanism
First Claim
1. A multiple-degree-of-freedom adjustment mechanism comprising:
- at least one support assembly; and
a plate supported by the at least one support assembly,wherein the at least one support assembly includes;
a bipod having a first rod and a second rod, one ends of which are fixed to each other at a top provided with a support section; and
a linear motion arrangement having a first movable member and a second movable member which are fixed to the other ends of the first rod and the second rod respectively, wherein the first movable member and the second movable member independently move in a linear motion direction,wherein each of the first rod and the second rod of the bipod has two limited-displacement flexible joints which provide elasticity in two orthogonal directions, respectively, andwherein each of the limited-displacement flexible joints comprises a flexible member shaped like a plate, which is placed between two bend limitation sections which are arranged in parallel with the flexible member.

Abstract
A multiple-degree-of-freedom adjustment mechanism with precise linear motion has structural robustness and allows easy reduction in weight and size, simple production and easy operation. The multiple-degree-of-freedom adjustment mechanism includes: at least one support assembly; and a plate supported by the at least one support assembly, wherein the at least one support assembly includes: a bipod having a first rod and a second rod, one ends of which are fixed to each other at a top provided with a support section; and a linear motion arrangement having a first movable member and a second movable member which are fixed to the other ends of the first rod and the second rod respectively, wherein the first movable member and the second movable member independently move in a linear motion direction.
