(54) | A device for opening and closing umbrellas |
(57) A device for opening and closing an umbrella includes a rod (7) which is slidable
in the upper part of the pole (3) for supporting the flexible canopy (2) of the umbrella
(1) and to which is articulated a first array of spokes (9) connected to the pole
by means of a second array of spokes (10) articulated to a collar (16) which is slidable
along the pole, and a third array of spokes (15) which interconnect the spokes of
the second array (10) and the pole above the slidable collar (16). The rod can be
moved between an extended position (corresponding to the closed condition of the umbrella)
and a retracted position (corresponding to the open condition of the umbrella) by
means of an external crank (24) and an internal rack-and-pinion transmission (21,
22), and a catch (26) is provided for locking the rod (7) in the extended position
and in the retracted position. |
