Title (EN) FLEXURAL PIVOT
(FR) PIVOT À LAMES FLEXIBLES
Abstract:
(EN) A flexural pivot is disclosed. The flexural pivot can include a plurality of flexure support members, each flexure support member having a plurality of flexure openings defined at least partially by a cantilevered extension portion. The flexural pivot can also include at least one flexure to rotatably couple the plurality of flexure support members to one another. The at least one flexure can have first and second flexible blades arranged in a cross configuration. The first and second flexible blades can be disposed in the flexure openings of the flexure support members, and the cantilevered extension portions, at least in part, can couple the first and second flexible blades to the flexure support members.
(FR) L'invention concerne un pivot à lames flexibles. Le pivot à lames flexibles peut comprendre une pluralité d'éléments de support de flexion, chaque élément de support de flexion comportant une pluralité d'ouvertures de flexion définies, au moins partiellement, par une partie d'extension en saillie. Le pivot à lames flexibles peut également comprendre au moins un joint flexible destiné à accoupler en rotation la pluralité d'éléments de support de flexion entre eux. Ledit joint flexible peut avoir des première et seconde lames flexibles agencées en conception transversale. Les première et seconde lames flexibles peuvent être disposées dans les ouvertures de flexion des éléments de support de flexion, et les parties d'extension en saillie, au moins en partie, peuvent accoupler les première et seconde lames flexibles aux éléments de support de flexion.
