摘要：
A joint (10) is described for connecting a pair of beams to pivot them between positions in alignment or beside one another, which is of light weight and which operates in a controlled manner. The joint includes a pair of fittings (16, 18), and at least one center link (20) having opposite ends pivotally connected to opposite fittings and having axes (36, 38) that pass through centerplanes (36, 38) of the fittings. A control link (24) having opposite ends pivotally connected to the different fittings controls their relative orientations, and a toggle assembly (26) holds the fittings in the deployed configuration wherein they are aligned. The fittings have stops (28, 30) that lie on one side of the centerplane opposite the toggle assembly.
