Claim Text:
1. A support apparatus for a sliding frame, said apparatus comprising: a stationary portion having a long axis parallel to a plane defined by said frame and including at least one magnetic insert disposed along said long axis defining a straight or curved path of translation; a movable portion fixedly or rotatively attached to said frame, including at least one magnetic insert and movable along said path of translation, wherein a magnetic field vector orientation of said at least one magnetic insert of said stationary portion and of said at least one magnetic insert of said movable portion are the same, and generate repelling forces and maintain a single state of contactless equilibrium of said repelling forces between said at least one magnetic insert of said stationary portion and said at least one magnetic insert of said movable portion at any point throughout said path of translation regardless of the orientation of said plane, wherein at least one side of said stationary portion includes at least two planes each oriented along at least a portion of a length of said at least one side of said stationary portion at an angle to each other and sharing an intersection line, wherein said at least one magnetic insert of said stationary portion is attached to each of said two planes of said at least one side of said stationary portion, and wherein at least one side of said movable portion includes a groove spanning at least a portion of a length of said at least one side of said movable portion, said at least one side of said movable portion includes at least two planes each oriented in parallel to a corresponding plane of said at least one side of said stationary portion, said at least two planes of said movable portion sharing an intersection line, wherein said movable portion includes at least one magnetic insert attached to each of said two planes of said movable portion; and wherein a line formed by the intersection of said two planes of said at least one side of said stationary portion and a line formed by the intersection of said two planes of said at least one side of said movable portion are parallel to each other and share in a same vertical plane.
