Abstract
A device for moving or positioning an object makes use of a track on a base and a circular groove on the platform. The platform holds the object. Balls are captured between the platform and the base which permit independent translation and rotation of the platform with respect to the base, by the simultaneous rolling and sliding of the balls. A mechanism for preloading and interlocking the base and the platform is also provided. The mechanism includes a shaft passing between the platform and the base and two channels formed in the platform. Elements disposed in the channels urge the shaft in opposite directions or selectively locking and disengaging of the platform and the base.
Claims17
A device for independent translation and rotation of an object comprising:
- a. base means with a first set of groove means defining a translation path for the object;
- b. platform means for holding said object, said platform means including a second set of groove means facing said base means for defining an axis of rotation for the object;
- and
- c. single coupling means disposed between said base and said platform means, said coupling means including rolling ball means which are continuously and directly engaged between said first and said second set of groove means, which rolling ball means simultaneously roll and slide for a translating motion of said platform means along said path and independently rotating said platform around said axis.
A device for positioning an object comprising:
- a. a base with a first and a second base groove for defining a translation path;
- b. a platform with a circular platform groove defining an axis of rotation facing said base grooves;
- and
- c. a plurality of balls continuously and directly engaged between said base grooves and said platform groove which balls roll and slide simultaneously within said grooves for translating said platform along said path and for independently rotating said platform about said axis.
