Abstract:
1. An articulated arm for an awning with improved elastic effect, comprising: an arm and a forearm, joined together by respective articulation configurations, located at adjacent ends of the same, which permits them to change between open and closed positions, a flexible tie bar located inside said arm, with a first end linked to at least one elastic traction element anchored to a fixed point on the arm and a second end anchored to the articulation configuration at the end of the forearm in order to produce, in consequence of a relative movement between the arm and the forearm on moving from the open position to the closed position, a lengthening of the elastic traction element and a consequent tension in the flexible tie bar, which generates a torque that tends towards the open position, and at least one elastic compression element located between a stop of the flexible tie bar and a support joined to the end of the arm in order to produce, in consequence of the relative movement between the arm and the forearm on moving from the open position to the closed position, a shortening of the elastic compression element and a consequent tension that adds to the tension in the flexible tie bar which contributes to increase the torque that tends towards the open position.
