Description

technical field [0001] The invention relates to umbrellas in daily necessities, in particular to a fully automatic self-opening and self-retracting straight bone umbrella. Background technique [0002] The straight-bone umbrellas used in society decades ago were mainly hand-opened umbrellas: the umbrellas were opened with both hands, and the umbrellas were closed with both hands. The straight bone umbrellas used in the society in recent decades are mainly semi-automatic umbrellas: generally the umbrellas are opened automatically and the umbrellas still need to be operated by both hands. In actual use, these umbrellas all need to be operated with both hands to open or close the umbrella, which cannot meet the requirements of people to open and close the umbrella with one hand in life (such as when one hand holds an item or holds a child, etc.) . Many people have been devoting themselves to the research of fully automatic umbrellas in the past twenty year...

AI Technical Summary

Problems solved by technology

[0003] 1) Umbrella opening is not smooth enough

[0004] 2) Large storage capacity

[0005] 3) The shape of the umbrella is not good when the umbrella is opened (the shape is more pointed)

[0006] 4) Not enough wind resistance

[0007] 5) Umbrella retraction action is unreliable

Or put it this way: the products produced by the existing automatic umbrella technology need a relatively tight umbrella surface to provide the starting force for closing the umbrella, and the umbrella cannot guarantee that the umbrella surface is always relatively tight in the manufacture and as a daily necessities in actual life. status, therefore existing fully automatic umbrella technology is unreliable or infeasible

[0008] 6) Unreliable locking of umbrella retracted state

[0009] 7) When the umbrella is in the closed state, the umbrella ribs are not compactly folded or the outer opening is large, the appearance is not good, the carrying is affected, and it is easy to hook other people's clothes or surrounding objects. The product is easily damaged or causes unsafeness for itself and others.

[0010] 8) The action of retracting the umbrella is accompanied by a large impact noise and vibration feel, which makes consumers displeased

[0011] Any of the above shortcomings can make the product unable to become a commodity, especially the 4th, 5th, and 6th, making the basic functions of the product obviously unreliable or infeasible, and the remaining few also make it difficult for consumers to accept this commodity
