Abstract
A hinge assembly between a lifting foil (12) and an associated flap (14) wherein the flap (14) includes a series of sections (20, 22). In one embodiment, each section (20,22) may be rotatably mounted by a single hinge (24) to the foil (12) and interconnected by a coupling device (34) to an adjacent flap section. Additionally, a shear key coupling device (40) may be arranged between each pair of sections (20, 22) substantially extending to the trailing edge of each section (20, 22).
Claims9
A hinge assembly for pivotally coupling a first structural member to a second structural member wherein said second structural member is composed of a plurality of sections arranged seriatim, comprising:
- means for mounting each of said sections to said first member, said mounting means having an axis of rotation;
- a first coupling means juxtaposed between each of said sections for pivotally interconnecting said sections, said first coupling means being disposed substantially perpendicular to said axis of rotation;
- a second coupling means juxtaposed between each of said sections for pivotally interconnecting said sections, said second coupling means being disposed substantially perpendicular to both said axis of rotation and said first coupling means, said second coupling means being substantially in alignment with said axis of rotation.
A hinge assembly for pivotally coupling a first structural member to a second structural member wherein said second structural member is composed of a plurality of sections arranged seriatim, comprising:
- means for mounting each of said sections to said first member, said mounting means having an axis of rotation and a central axis;
- a first coupling means juxtaposed between each of said sections for pivotally interconnecting said sections, said first coupling means being disposed substantially perpendicular to said axis of rotation and substantially in alignment with said central axis;
- a plurality of second coupling means for pivotally interconnecting said sections, each of said second coupling means being disposed in one of said sections and extending to an adjacent section for pivotally coupling said adjacent section to said one section, said second coupling means being substantially in alignment with said axis of rotation.
