Abstract: A prosthesis or orthosis for a joint, such as an ankle, which includes a first body, a second body, and an articulated joint between the first and second bodies, the articulated joint allowing the rotation of the first and second bodies with respect to one another around a joint rotation axis. It further includes a locking mechanism configured to selectively lock the rotation between the first and second bodies in one direction, when it is in a locked configuration, and a transmission mechanism such that a rotation of the joint rotation axis generates a movement of a lockable part of the locking mechanism. The axis of the movement of the lockable part is shifted relative to the joint rotation axis and the transmission mechanism includes a reducer configured to reduce effort to lock the rotation of the first body with respect to the second body.

Abstract: The present invention relates to a protective foldable cage (100) adapted to flying drones. It comprises several ribs linked at their extremities by a ring and comprising on their length several connexion points allowing strings to join each of the adjacent ribs. The length of the string corresponds to the maximal angular shift between the first and the last ribs. The protective cage further comprises easily removable locking means adapted to maintain the ribs at predetermined relative angular position once deployed. The resent invention further relates to a system comprising such a protective cage and a drone support, as well as a method of protection of flying drones.
