Umbrella opening and closing mechanism, characterized essentially by the fact that it comprises a plurality of articulated tornapuntas forming parallel parallelograms articulated jointly with the rods of the umbrella and the upper section of the triangle thereof, to whose tornapuntas are connected arms to each other in the end flocked by their opposite ends to a sliding sleeve in the triangle and connected in turn to a brace arranged along the tringla and operated by a lever hinged on the handle of the umbrella, whose tornapuntas have joined one of its sections by mediation of elastic braces to a sliding ring mounted around the triangle and in turn resiliently pushed by a spring that tends to keep the tornapuntas in their extended position.
