Definitions

  • the invention relates to an umbrella with a shaft and a frame carried on the shaft and comprised of a spider formed by a plurality of ribs over which is spanned a canopy and by respective spreader struts pivoted on the ribs and on an actuator slidable longitudinally along the shaft.
  • At least one brace is pivoted at an inner end on a respective one of the spreaders and at an outer end on a slide that is movable along an outer end region of the respective rib.
  • Such an umbrella has the advantage that the long free lever arm of the rib between its free end and the pivot between the rib and the outer end of the respective spreader is substantially reduced and the find forces acting from blow on the open umbrella are better resisted and transmitted to the entire umbrella frame.
  • a length of the rib between its outer end and its pivotal connection with the respective spreader is at least equal to the length of the respective brace plus the length of the respective spreader between its pivotal connection with the respective rib and with the respective brace.
  • the ribs be comprised of plastic and that in open condition a tension of the canopy on the elastically bent ribs and on the braces is such that only a sectoral inversion of the frame with the canopy is possible and a complete inversion of the canopy is inhibited circumferentially.
  • Making the ribs as plastic bars has with regard to metallic profiled ribs the substantial advantage that even after an inversion caused by a powerful gust, there is no irreversible deformation of the ribs, but the umbrella can be restored to its normal use condition.
  • the plastic spreaders have a diameter of 2 to 6 mm, preferably 3 to 4 mm, since the small diameters gives sufficient strength without adding unnecessarily to the weight of the umbrella. It is further preferred that the braces be made of plastic, to be able to have further good strength with light weight. In addition this also works against irreversible deformation.
  • the resistance of the umbrella to wind force is increased when in open condition the spider with the canopy and frame form a spring element acting as a damping member that resists inversion.
  • the invention provides that the slides are each formed by a tube engaged around the respective rib and formed with a nose in turn forming the pivot.
  • each brace has at least where it engages the respective brace a U-section in which a shoe carried by the respective slide can shift.
  • the diameter of the brace is smaller than the interior width of the U-section it is possible to next the brace in the rib when the umbrella is closed.
  • the umbrella is even more resistant to wind from below the frame, since the rib cannot shift further in the opening direction because of the slide.
  • the abutment is mounted on the respective rib at a spacing from its outer end that is effective via the respective brace to curve the respective rib so as to prestress the frame when open in a direction resisting inversion since in this manner the force and the necessary wind strength is increased that is necessary to invert the umbrella frame.
  • FIG. 1 is a perspective view of the umbrella according to the invention in opened condition
  • FIG. 2 is the umbrella of FIG. 1 in closed condition.
  • An umbrella 1 shown in FIG. 1 is formed by a shaft 2 and a frame 3 carried on the shaft 2 and formed by a plurality of ribs 4 carrying a canopy 5 formed by spreader struts 6 that are pivoted on the respective ribs 4 and on a slidable actuator 7 movable longitudinally on the shaft 2 .
  • each rib 4 between its outer end and its pivotal connection with the respective spreader 6 is at least equal to the length of the respective brace 8 plus the length of the respective spreader 6 between its pivotal connection with the respective rib 4 and with the respective brace 8 .
  • the ribs 4 and the braces 8 are made of plastic so that when open the tension is determined by the bending elasticity of the ribs 4 and the braces 8 so that only a sectoral inversion of the frame 3 with the canopy 5 is possible and a complete inversion of the canopy 5 is not possible.
  • the plastic ribs and spreaders have a diameter of 2 to 6 mm, preferably 3 to 4 mm.
  • the frame 3 with the canopy 5 in the opened condition form a resilient assembly with damping action that inhibits inversion and where the spring strength of the damping element is such that only a localized sectoral inversion is possible and that the tensioned damping element effects automatic restoration when wind pressure drops.
  • each rib 4 is formed where it engages the respective brace 8 of U-section and holds a slide shoe of the respective brace 8 so that the diameter of the brace 8 is smaller than the interior width of the U-section.
  • the ribs 4 having braces 8 each have an abutment for limiting the travel of the respective slide 9 toward the shaft 2 .
  • the abutment is provided on the rib 4 at a spacing from its outer end that effects via the brace a bending of the respective rib 4 toward the open position of the frame 3 so as to be effective opposite to any inversion forces in order that the strength of the frame 3 is further increased and a spring element is employed as damper.
