Abstract:
1. A retaining device, comprising a retaining barrier including a support frame for supporting a retaining mesh, the support frame including at least four arms, wherein the support frame is configured to assume a non-operating closed configuration and an operating radial configuration, wherein, in the operating radial configuration, each arm is oriented along a respective radial direction with respect to a center axis of the support frame, the arms being coplanar in a plane perpendicular to the center axis, and wherein two first arms of said four arms form a single piece, being successive sections of a beam, and are aligned to each other and oriented in a same radial direction both in the non-operating closed configuration and in the operating radial configuration, and the remaining two second arms are structurally independent of each other, wherein in the non-operating closed configuration, one of the remaining two second arms of the four arms is located on a first side of one of the two first arms and the other of the remaining two arms of the four arms is located on a second side of the other of the two first arms, wherein the first side and the second side are opposite sides relative to the two first arms, the arms remaining coplanar within said plane, the retaining device being configured to be used for retaining snow, avalanches, earth, rocks, or similar materials to be retained, the retaining barrier being configured for receiving a load of material to be retained and for stopping, or at least limiting, an advancing movement of the material to be retained.
