  • FIG. 9 is a vertical cross section of a detail of the hinge connection of the foldable member to the crown.
  • FIG. 10 is an enlarged fragmentary perspective view of a detail of the foldable member of FIG. 8.
  • the umbrella includes a stick 1 comprising two telescopic sections 2 and 3 with section 2 being of circular cross section and section 3 being of polygonal cross section.
  • a polygonal-shaped mouth is provided adapted to receive the polygonal-shaped stick section 3.
  • a conventional locking device 4 is also provided in the area of the mouth, whereby when the umbrella sticks are fully extended, they are releasably locked.
  • a handle 5 is provided at the end of stick section 3, while a crown 6 is fixed to the end of the stick section 2.
  • a runner 24 on the umbrella stick 1 and an auxiliary runner 27 slide on the track between the main runner 24 and the crown 6.
  • a stretcher member 25 is hinged to the flange 26 on the main runner 24 at one end thereof, and elongated rigid hinge bracket 14 is hingedly connected to the other end of the stretcher member 25.
  • a dome rib 7 is fixed to the hinge bracket 14 and extends longitudinally therefrom.
  • a strut 29 is hinged to the auxiliary runner 27 at one end thereof, and at the other end, it is hinged at hinge point 30 midway of the stretcher member 25.
  • a link member 31 is hinged to the strut 29 at hinge point 33 and at the other end thereof it is hinged to the end of the hinge bracket 14 at hinge point 15. The link member 31 has a slight kink 32 near the hinge point 15.
  • Foldable members T1 and T2 are provided between the hinge bracket 14 and the crown 6.
