Multi-folded umbrella having a reduced closed volume

Abstract

The invention relates to an improved multi-folded umbrella having a reduced closed volume, which includes a shaft with a crown secured to its upper end, a slider slidably provided on the shaft, and rib sections pivoted to the crown and the slider consisting of struts, tensions ribs, and spokes. The rib sections of the frame are positioned in side-by-side relationship, either clockwise or anti-clockwise, when the umbrella is closed, wherein the umbrella can be two-folded, three-folded, four folded, five-folded, or more, and between the rib sections, various connecting assemblies are provided. Hence, the present umbrella can be used more conveniently and effectively.

1 . A multi-folded umbrella having a reduced closed volume including a shaft with a crown secured to its upper end, a slider slidably provided on the shaft, and rib sections pivoted to the crown and the slider consisting of struts, tensions ribs, and spokes; the characteristic is the rib sections being positioned in side-by-side relationship when the umbrella is closed, wherein the umbrella can be two-folded, three-folded, four folded, five-folded, or more, and between the rib sections, various connecting assemblies are provided. 
   
   
       2 . A multi-folded umbrella having a reduced closed volume as claimed in  claim 1 , when the umbrella is a four-folded umbrella, which includes a first connecting assembly, a fifth connecting assembly, a fourth connecting assembly, and a second connecting assembly counted from the shaft, wherein the first connecting assembly includes a strut rib, a branch rib, and a tension rib, in which the tension rib has its inner end linked to the branch rib, and the branch rib has its outer end pivoted to the strut rib and a U-shaped holder; the fifth connecting assembly includes a first strut, a second strut, a first tension rib and a second tension rib, in which the first tension rib has its outer end linked to the outer ends of the second strut rib and a cover, the second tension rib has its inner end linked to the first strut rib, and the first strut rib has its outer end pivoted to the second strut rib and the cover; the fourth connecting assembly includes a first strut, a second strut, a first tension rib and a second tension rib, in which the first tension rib has its outer end linked to the inner ends of the second strut rib and a holder, the second tension rib has its inner end linked to the first strut rib, and the first strut rib has its outer end pivoted to the second strut rib and the holder; the second connecting assembly includes the strut rib, a spoke, and the tension rib, in which the tension rib has its outer end linked to the inner end of the spoke while the strut rib has its outer end linked to the spoke, and both of which are pivoted to a U-shaped cover having an opening above.
