ABSTRACT:
Embodiments of the present invention are directed to a linear motion flexural apparatus to provide friction-free linear travel for large stroke motion. In one embodiment, a linear motion flexural apparatus comprises a first member having a first surface, and a second member having a second surface which is spaced from the first surface of the first member. One of the first member and the second member is movable relative to another one of the first member and the second member in a linear direction. At least one sheet is disposed between the first surface of the first member and the second surface of the second member. Each sheet has a first edge portion and a second edge portion generally opposite from the first edge portion. The first edge portion is attached to the first surface of the first member. The second edge portion is attached to the second surface of the second member. Each sheet has a curved portion with a shape which is substantially unchanged during movement between the first member and the second member in the linear direction.
