Patent ID: 8608400

Claim:
A position arrangement device comprising: a first base; a second base spaced apart from the first base; and a joint module between the first base and the second base, the joint module configured to adjust a position of the second base relative to the first base based on elastic flexion in the joint module, the joint module including, a flexure including, a separated portion supported by the first base, a coupled portion, and a flexible portion between the coupled portion and the separated portion, the flexible portion configured to elastic flexion such that a distance between the separated portion and the second base increases or decreases, a preload member configured to maintain a constant distance between the separated portion and the first base during elastic flexion of the flexible portion, a body secured to the second base and coupled to the coupled portion, an extension member extending from the body toward the separated portion, and an adjusting member configured to adjust a distance between the extension member and the separated portion, the adjusting member including a head integrally connected to a first screw portion and a second screw portion, the first screw portion and second screw portion having different thread pitches and being concentrically aligned so the head and first and second screw portions are configured to be rotated together, the first screw portion screwed to the extension member, and the second screw portion screwed to the separated portion of the flexure.
