ABSTRACT:
The invention pertains to a double gimbal joint construction for rigid conduit or duct systems. The joint includes a gimbal assembly consisting of a pair of sheet metal concentrically related rings maintained in radial spaced relationship by annular spacers located at 90.degree. circumferential intervals about the rings wherein pivot pins extend through the spacers. Annular conduit receiving collars are pivotally attached to the gimbal ring assembly by fork lugs pivotally connected to the spacer and pivot pin assemblies intermediate the inner and outer rings. The construction permits a "double" shear relationship to be established at the fork lugs and pivot pins improving anti-shear characteristics, and the sheet metal construction reduces costs.
