  • the plate is preferably connected to return or tensioning springs 501 that are connected to sheet 500 by eyelets, so as to pre-tension the sheet, constraining the sheet to the vertical movement of plate 500.
  • the movement of plate 311 through the threaded staff 700 allows the actuation of the telescopic sticks of the umbrella through wheels 410, in turn connected to the inner screw 405 through clutch 401.
  • the telescopic movement of the sticks that support the umbrella sheet is obtained through the connection of the staff inner screw 405 with the block sliding on screw 406 arranged into the staff outer tubing 402.
  • the movement along the prevailing direction X of said movement unit 300 can be ensured, in place of the control screw or threaded staff 700, by cables, with or without reel for the winding thereof, intended for the vertical pulling of plate 306" ⁇ on the support guides 800.
  • said movement unit 300 in replacement of the control screw or threaded staff 700, comprises a rack staff, associated to a gear controlled by said motor means, for example positioned as desired, for transforming the rotational motion into translatory motion from the bottom upwards, and vice versa, of plate 306 on the support guides 800.
  • said movement unit 300 comprises an actuator, consisting of a motor with telescopic stem, in replacement of the control screw 700, intended for the vertical translation movement of plate 306 on the support guides 800.
  • said stick movement unit wheels 410 which control the inner screws of the sticks, can be replaced with other solutions with gears, cables, with or without reels for the winding thereof, or with electrical motors for each stick.
  • the umbrella portion consisting of the covering, once inserted from the top into the shaft, is not visible anymore .
  • the shaft therefore becomes the case of the umbrella/beach umbrella, which thus obtains a permanent protection even when not used for a long time.
  • the open umbrella, subject of the invention described can take up a horizontal position, relative to the shaft, but it is also capable of taking up positions similar to the conventional umbrellas, that is, inclined downwards or also upwards, according to the construction type .
  • the umbrella opens as follows.
  • the threaded staff starts the rotation, causing the rise of the stick translation unit which, at the end of the stroke, makes the wheels adhere to the movement unit for the extension of the sticks.
  • the opening may be actuated as desired, that is, by a remote control or by a button on panel .
  • the threaded staff 700 operates the stick movement a.nd translation units.
  • a first step provides to the rise of the translation box which, once the end of stroke position has been reached, for example through a special electrical contact, disconnects the electro-magnetic brake 305 making the nut screw 301 idle and thus releasing the same from the threaded staff 700 .
  • sticks 400 reach a substantially horizontal position so that the friction wheels 410 come into contact with the sliding or friction surface 310 of plate 311.
  • Screw 700 is connected to nut screw 301, intended for adhering to staff 700 through the electro-magnetic brake 305, which disconnects when the entire stick translation box has risen and has reached the end of stroke relay.
  • the screw is further connected to the sticks, which have been idle so far and which, in the adhesion to the sliding surface 310 that is integral to plate 311, start moving controlled by the inner screw 405. In turn, the screw is controlled by the rotation of wheel 410.
  • the inner telescopic staff 403 extends or retracts moving sheet 502 therewith, which constantly remains tensioned by the effect of the tensioning springs 501.
  • the sheet tensioning plate 500 on guides, continuously slides along the threaded staff or control screw 700, keeping the distance thereof from the stick ends almost constant.
  • the control screw 700 pulls the sheet tensioning plate 500, with vertical translation movement, thanks to the fact that plate 500 itself cannot rotate on itself as it is guided by the guide bars 800 arranged into shaft 200.
  • Said plate 500 runs through the entire shaft 200 keeping sheet 502, intended for extending for forming the umbrella covering, tensioned through springs 501.
  • plate 500 is eliminated, sheet 502 is free and the tensioning thereof is ensured by counterweights arranged at the end of the sheet itself .
  • the stick guiding stop 415 allows maintaining the sticks in equidistant position, also performing the task of giving a counter-thrust to the stick, such as to allow the best adhesion of the screw connecting wheel 410 to the sliding surface 310.
  • the adhesion of the screw connecting wheel 410 is ensured by the thrust spring 313.
  • the umbrella When the umbrella reaches the closing position, the telescopic sticks arrange in vertical position and the movement unit in low position, the whole contained within shaft 200; in other words, the sticks gather upwards and insert into shaft 200.
  • the umbrella according to the present invention allows overcoming the disadvantages of the umbrellas of the prior art .
  • the mechanism used for the umbrella can found application for any other type of protection such as rain umbrella, sun protection on boats or else, it may be made with different configurations, provided it can then be automatically reinserted into the shaft, etc.
