Abstract
An improved flexural pivot design simplifies the structure, fabrication, assembly, and integration into a device. A set of flexures 200 is affixed to two surfaces of a stationary member 100 and a single surface of a rotational member 300. The set of flexures follow opposing centers of curvature 411 and 412 to provide a stable center of rotation 400 and allow repeatable limited-angle rotational motion.
Claims14
A flexural pivot device, comprising:
- a stationary member having a first and second surfaces,
- a rotate-able member,
- a first flexible member affixed between said first surface of said stationary member and said rotate-able member such that said first flexible member is preloaded in a curved form with an approximate center of curvature above said first surface of said stationary member, and
- a second flexible member affixed between said second surface of said stationary member and said rotate-able member such that said second flexible member is preloaded in a curved form with an approximate center of curvature above said second surface of said stationary member.
