Definitions

  • the invention provides a particularly simple device of this type, which consists, according to the main feature of the invention, of a pressure disk of resilient material, preferably of sheet steel, which is firmly supported or clamped in the crown of the umbrella, and the rim of which cooperates with projections provided at the inner rib sections adjacent to their linking points, in such a manner as to exercise on said ribs a force whereby they are urged apart.
  • the pressure disk is preferably of slight convexity for improved spring action.
  • the structure according to the invention provides the advantage of simple assembly and invariably reliable service through a long period of use.
  • Fig. 1 being a longitudinal sectional View taken through the crown of the umbrella with the upper portions of the ribs linked thereto;
  • Fig. 2 showing on a greatly reduced scale the rib structure in its closed position, with its initial opening which is achieved by the means provided by the invention.
  • numeral l designates the top part of this stick, on which the crown 2 is stuck.
  • the inner ends of the ribs or rib sections 3 are linked or bound in the manner known to the crown.
  • Each rib or rib section 3 has a projection 4 which coacts with the free rim of a disk 5, which in the embodiment shown by way of example is centrally supported in the crown by means of the nut 6, which also serves for locating the crown 2 at the end of the stick.
  • the disk 5 is of resilient material, preferably of sheet steel, so that it exercises on the projections 4 a resilient pressure whereby the ribs or rib sections are moved into an initial angular position, so that, as can be seen from Fig. 2, the rib structure is given a resilient initial opening.
  • a collapsible umbrella comprising a telescopic stick, a crown fixed to said stick, and telescopic ribs linked to said crown, the provision of a projection on each rib adjacent to its linking point and a resilient sheet steel pressure disk connected to the crown and having a free rim portion which is adapted to bear on said projections when the ribs are in a folded position and to exercise pressure on said ribs to urge them apart.
