  • said effortless unfolding structure of sunshade umbrella also comprises a bearing component 5 for the pulling rope.
  • the said first end part 21 winds part of the said bearing component 5 .
  • Said bearing component 5 can be of any appropriate structure. Please refer to FIG. 1 to FIG. 3 , in the embodiment of the present invention, said bearing component for the pulling rope 5 is a bearing block with a groove, and the first end part 21 winds part of said groove.
  • the oblique rod 10 of the sunshade umbrella can be fixed to the post 20 by any appropriate ways.
  • the said effortless unfolding structure of sunshade umbrella also comprises a fixing block 6 for the oblique rods.
  • Said bearing component 5 for the pulling rope is mounted on the said fixing block 6 for the oblique rod.
  • Said first end pat 21 is fixed on the said fixing block 6 for the oblique rods.
  • the oblique rods 10 are pivotally connected with the fixing block 6 and the fixing block 6 is fixed on the post 20 .
  • Said bearing component 5 for the pulling rope can be mounted on said fixing block 6 for the oblique rod; or otherwise, said bearing component 5 for the pulling rope and said fixing block 6 for the oblique rods can be formed integrally.
  • the bearing block 5 with the groove and said fixing block 6 for the oblique rods are formed integrally. That is to say, the groove is actually a protruded groove of the fixing block 6 for the oblique rods and preferably has a gradual changing diameter.
  • Said fixing block 6 for the oblique rods can be fixed to the post 20 of the sunshade umbrella in any appropriate structures.
  • said effortless unfolding structure of sunshade umbrellas also comprises a locking plate 7 .
  • Said fixing block 6 for the oblique rods is fixed to the post 20 of the sunshade umbrella by means of the said locking plate 7 .
  • the oblique rods 10 are pivotally connected with the fixing block 6 for the oblique rods by means of a connecting head 30 .
  • the cantilever is mounted between the two oblique rods 10 which support the umbrella fame.

  • FIG. 2 it is an unfolding status of the umbrella.
  • the spring inside the cantilever 1 is in its initial status which can be considered that there is no compressive force.
  • FIG. 3 it is an folding status of the umbrella. Since the length of the wire steel rope won't change, and as the oblique rods 10 rotate downwards and inwards relative to the post 20 , the more of the wire steel rope will wind the groove. For example, the steel wire rope in FIG. 3 wind almost a quarter of the groove, and thus the difference in size is produced.
  • the steel wire rope makes the end face snap-fit piece compress the spring to produce a reactive force against the folding action. However, the rebound force of the spring is less than the force that is needed to unfold the umbrella, so that the umbrella can be folded successfully.
  • the effortless unfolding structure of sunshade umbrella is ingeniously designed, concise in structure, and can facilitate to open umbrella in a labor saving way.
  • the overall appearance will not be damaged. It is suitable to be promoted and applied on a large scale.
