elescopic mechanism for deploying and folding large professional static umbrellas, for outdoor and semi-outdoor spaces which is characterised by a central telescopic pole (1,3) where in the inner main part of it (3) a specially shaped counterweightis formed (7), whereas external it bears a series of suspenders (9, 17, 23) and articulated ligaments (25) upon which is seated and radially develops and folds an assembly of beams (10), buttresses (15) and sub-levers (16) of certain geometrical shapes and relationships. A suspender (9) which slides external of the telescopic pole (1,3) in a specially shaped plastic sliding guide (6) bears in a preselected and specially shaped reception (18) a suspended, manually operated articulated mechanism for complete deployment and locking (19, 20) which in co-operation with the suspender (21) which is rigidly attached in the external part of the telescopic pole (1, 3) with the use of a specially shaped plastic tightening and retention guide (21.1),completes along with the beam ejector (24) the autonomous procedure of complete deployment of the membrane (8) which folds onto the beam assembly (9) and the procedure of locking of the overall telescopic mechanism, protecting it from random operations. |
