A rotational joint of intra-extra rotation for assistance of the movement of intra-extra rotation of a shoulder of a user. The rotational joint features a first circular guide arranged to rotate about a first rotation axis and a second circular guide arranged to rotate about a second rotation axis that is parallel to the first rotation axis. A support element is arranged to support the first and the second circular guides. The first and the second circular guide are pivotally connected by a conical wheel having a third rotation axis perpendicular to the first rotation axes and said conical wheel being pivotally constrained to the support element.

The object of the present invention is a new configuration of torsional spring with a flat structure, capable of ensuring response linearity, modelling ease and accuracy, versatile use while safeguarding the possibility of the inner passage of wiring or of any accessory components along the transmission/torsion axis.

Planar torsional spring

A transmissive joint has an elastic response for transmitting a torsional load capable of ensuring the transmission in the absence of coaxiality between two actuating and actuated devices, and allowing the internal passage of cabling or possible accessory components along the axis of transmission/torsion.

Joint for transmitting a torsional load with elastic response

A kinematic chain comprises a first pulley, arranged to rotate about a rotation axis x, and a second pulley arranged to rotate about a rotation axis y. The kinematic chain comprises then at least one connecting element comprising at least one passage having at least one rotating element, said or each connecting element also comprising at least one interface arranged to connect the connecting element to an adjacent connecting element or to a pulley, generating a rotational constraint about a rotation axis z. The kinematic chain also comprises a transmission element arranged to develop along a determined path for transmitting a rotational motion between the first pulley and the second pulley. The transmission element is adapted to be, in use, fixedly in contact with said or each rotating element by a constraint of rolling friction, in order to allow a modelling the determined path according to a predetermined geometry.

Kinematic chain for transmission of mechanical torques

A kinematical chain () for assisting a spherical motion of an anatomical joint () of a finger of the hand () of a user, said anatomical joint () having centre of rotation P and being arranged for allowing a relative motion of a finger of the hand () with respect to a portion of hand () of the user, said finger of the hand () defining a longitudinal direction &#x3b4;. The kinematical chain () comprises a first rotational joint () engaged to the finger of the hand () and to a first connection link (), said first rotational joint () arranged to provide a relative rotation &#x3b1; between the first connection link () and the finger of the hand () about a rotation axis x coincident with the longitudinal direction &#x3b4;. The kinematical chain () also comprises a third rotational joint () engaged to the portion of hand () and to a second connection link (), said third rotational joint () arranged to provide a relative rotation &#x3b3; between the second connection link () and the portion of hand () about a rotation axis z integral to the portion of hand (). The kinematical chain () comprises then a second rotational joint () engaged to the first connection link () and to the second connection link (), said second rotational joint () arranged to provide a relative rotation &#x3b2; between the first connection link () and the second connection link () about a rotation axis y. The rotation axes x, y and z intersect in a centre of rotation O, in such a way that the kinematical chain () allows a spherical motion of the longitudinal direction &#x3b4; with respect to the portion of hand () about the centre of rotation P.
