Abstract
Abstract A multi-post gimbal mechanism for imparting motion to an object about a cer of rotation including a frame for supporting the object and a plurality of elongated posts coupled to the frame so as to permit orbital rotation of the frame about each of the coupling points. Each of the elongated posts is selectively adjustable in position and drive means are coupled to the elongated posts to selectively adjust the position. The drive means are supported on a mounting base and are pivotally attached to the mounting base such that each drive mechanism can rotate about an axis that is orthogonal to the longitudinal axis of its corresponding elongated support post.

Claim 1
Independent Claim
147 words
A multi-post gimbal mechanism for imparting motion to an object about a center of rotation comprising: a frame for supporting said object; a plurality of elongate posts, each coupled to said support frame at a coupling point so as to permit orbital rotation of said frame about each said coupling point, each of said elongate posts being selectively adjustable in position; drive means coupled to said plurality of elongate posts for selectively adjusting the position of each of said elongate posts; a mounting base, said drive means being connected to said mounting base; each of said elongate posts including a first end and a second end, each said first end being connected at said coupling point; and said mounting base including a plurality of arcuate guides connected thereto, the second end of each of said elongate posts being positioned in one of said plurality of arcuate guides.
Claim 2
Dependent Claim
147 words
A multi-post gimbal mechanism for imparting motion to an object about a center of rotation comprising: a frame for supporting said object; a plurality of elongate posts, each coupled to said support frame at a coupling point so as to permit orbital rotation of said frame about each said coupling point, each of said elongate posts being selectively adjustable in position; drive means coupled to said plurality of elongate posts for selectively adjusting the position of each of said elongate posts; a mounting base, said drive means being connected to said mounting base; each of said elongate posts including a first end and a second end, each said first end being connected at said coupling point; and said mounting base including a plurality of arcuate guides connected thereto, the second end of each of said elongate posts being positioned in one of said plurality of arcuate guides.
