Abstract
A first guide rail (11), and a second guide rail (12) and a third guide rail (13) that are parallel to each other are installed on a base (2) so as to be perpendicular to each other, and these guide rails are rotated about shafts (4) installed on both ends. When the guide rails are rotated, an indication bar (3) installed on a rotor (1) is moved synchronously with the movement of the guide rails, so that the rotor (1) is also rotated. A slider (22) installed on the indication bar (3) slides along a slit (21) of the third guide rail (13). Then a rotation angle of the rotor (1) about the indication bar (3) is determined by the distance between the guide rails.
Claims22
A rotation system with three degrees of freedom comprising a rotor comprising a part or a whole of a sphere, an indication bar, at least one slider, at least one base, four shafts, six bearings, and three first to third guide rails,
- wherein
- said rotor includes said indication bar,
- said first guide rail is installed on said base by using two said shafts and two said bearings,
- said second guide rail and said third guide rail are installed on said base by using two remaining said shafts and four remaining said bearings, and
- at least one said slider is installed on or concatenated with said indication bar, moreover wherein
- said second guide rail rotates centering around two said shafts supporting said second guide rail, sliding said indication bar along said first guide rail,
- said first guide rail rotates centering around two said shafts supporting said first guide rail, sliding said indication bar along said second guide rail, and
- said rotor rotates centering around said indication bar, sliding at least one said slider along said third guide rail.
A rotation system with three degrees of freedom comprising a rotor comprising a part or a whole of a sphere, an indication bar, at least two sliders, at least one base, four shafts, six bearings, and three first to third guide rails,
- wherein
- said rotor comprises said indication bar,
- said first guide rail is installed on said base by using two said shafts and two said bearings,
- said second guide rail and said third guide rail are installed on said base by using two remaining said shafts and four remaining said bearings, and
- at least two said sliders are installed on or concatenated with said indication bar, moreover wherein
- each of said second guide rail and said third guide rail rotates centering around two said shafts supporting said second guide rail, sliding said indication bar along said first guide rail,
- said first guide rail rotates centering around two said shafts supporting said first guide rail, sliding at least two said sliders along said second guide rail and said third guide rail, and
- said rotor rotates centering around said indication bar, sliding at least two said sliders along said second guide rail and said third guide rail.
A rotation system with three degrees of freedom comprising a rotor comprising a part or a whole of a sphere, an indication bar, at least two sliders, at least one base, four shafts, six bearings, and four first to third and sixth guide rails,
- wherein
- said rotor comprises said indication bar,
- said first guide rail and said sixth guide rail are installed on said base by using two said shafts and two said bearings,
- said second guide rail and said third guide rail are installed on said base by using two remaining said shafts and four remaining said bearings, and
- at least two said sliders are installed on or concatenated with said indication bar, moreover wherein
- each of said second guide rail and said third guide rail rotates centering around two said shafts supporting said second guide rail, sliding at least two said sliders along said first rail and said sixth guide rail,
- each of said first guide rail and said sixth guide rail rotates centering around two said shafts supporting said first guide rail, sliding at least two said sliders along said second guide rail and said third guide rail, and
- said rotor rotates centering around said indication bar, sliding at least two said sliders along said second guide rail and said third guide rail.
