摘要： Exoskeleton kinematic chain arranged to pivotally connect a first element to a second element, said first element comprising two pivot points A1 and B1 located at a distance A1B1, said second element comprising two pivot points A2 and B2 located at a distance A2B2. The exoskeleton kinematic chain comprises a first external link pivotally connected to the first element at the pivot point A1 and a first end link pivotally connected to the first external link at a pivot point D1, said pivot point D1 being located at a distance A1D1 by the pivot point A1. The exoskeleton kinematic chain comprises then a second external link pivotally connected to the second element at the pivot point A2, and a second end link pivotally connected to the second external link at a pivot point D2, said pivot point D2 being located at a distance A2D2 by the pivot point A2. The exoskeleton kinematic chain also comprises a first intermediate link pivotally connected to the first element at the pivot point B1 and integrally connected to the second end link at a junction point C2, a second intermediate link pivotally connected to the second element at the pivot point B2 and integrally connected to the first end link at a junction point C1. The first and the second end link are pivotally connected to each other at a pivot point M. Defining ==θ, for any value of θ, the projections of the pivot points A1, B1, A2, B2 in a plane Π, lay in a circumference K having center O and radius r=A1D1=A2D2=D1B2=MB2=D2B1=MB1, in such a way that decreasing the value of θ the first and the second element rotate with respect to each other about an axis z orthogonal to the plane Π and passing through the center O in the direction for which the point A1 is overlapped to the point B2.

The first and the second end link are pivotally connected to each other at a pivot point M. Defining ==θ, for any value of θ, the projections of the pivot points A1, B1, A2, B2 in a plane H, lay in a circumference K having center O and radius r=A1D1=A2D2=D1B2=MB2=D2B1=MB1, in such a way that decreasing the value of θ the first and the second element rotate with respect to each other about an axis z orthogonal to the plane π and passing through the center O in the direction for which the point A1 is overlapped to the point B2.
