Abstract
A flexure hinge with two material segments connected to each other via a material tapering to a thin spot which defines a pivot axis between the two material segments. The material segments are provided with recesses such that the strength existing in the thin spot with respect to normal stresses or bending stresses is kept largely constant within a distance from the thin spot.
Claims15
A flexure hinge comprising:
- (a) a first material segment and a second material segment monolithically connected together along a thin spot which defines an imaginary pivot axis between the first material segment and the second material segment, at least one of the first material segment and the second material segment having a thickness along a direction X which tapers in a tapering zone along a direction Y perpendicular to the direction X to a minimal thin spot thickness, the imaginary pivot axis extending in a direction Z perpendicular to the direction X and the direction Y;
- (b) at least one recess positioned in the tapering zone of the at least one of the first material segment and the second material segment;
- and
- (c) wherein the at least one recess is formed so that a plane defined by the direction X and the direction Z passing through the at least one recess intersects the respective material segment to define cross section areas spaced apart along the direction Z and comprising geometric shapes the width of which along the direction Z decrease with increasing distance along the direction Y from the position of the thin spot along the direction Y.
