Umbrella with outward turning-preventing function

Abstract

The invention discloses an umbrella with outward turning-preventing function. The umbrella comprises a main rib, a plurality of umbrella cloth branch ribs and a plurality of drawing line bodies, wherein the plurality of umbrella cloth branch ribs are connected to and extended from the upper end of the main rib; and the plurality of drawing line bodies are respectively wound around the main rib along one umbrella cloth branch rib and then are fixed along another umbrella cloth branch rib. A firm and stable inward tension is provided for the umbrella through the combination of the plurality of umbrella cloth branch ribs and the plurality of drawing line bodies, so that the umbrella resists the blowing of reverse strong wind, then the umbrella ribs are prevented from being turned outwards, bent, deformed even broken and the service life of the umbrella is prolonged.

Description

technical field [0001] The invention relates to an umbrella with the function of preventing valgus, in particular to an umbrella in which the ribs of the umbrella are provided with tension wires to form the function of wind resistance and anti-turning. Background technique [0002] Currently commonly used umbrellas, the ability of the umbrella cloth and the umbrella frame to resist the wind has reached a certain level. In the face of the strong wind blowing from the front, the umbrellas on the market can resist it, and will not The structure of the parachute was damaged due to the strong wind. [0003] However, if a sudden strong wind blows from the opposite direction, most umbrellas will reversely fold because they cannot withstand the force of the reverse wind, resulting in the disadvantage of bending, deforming or even breaking the ribs. The umbrella tool is thus damaged and unusable. [0004] Such as Figure 1 to Figure 3 As shown, a commonly used umbrella rib structur...

AI Technical Summary

Problems solved by technology

[0007] 1. The umbrella rib structure 1 is designed to withstand the positive wind force, and is not designed for the reverse wind force;

[0008] 2. In addition to the umbrella main rib 11, the umbrella cloth ribs 15, the supporting ribs 16 and the supporting ribs 17 are all thinner metal elements, and their ability to withstand the reverse wind force is relatively insufficient;

[0009] 3. The design of the pivotal joints between the bones is weak, and the degree of reverse wind force they withstand is not enough

[0010] Based on the above reasons, once the rib structure 1 is hit by a reverse wind force that exceeds its tolerance level, the rigid connection cannot bear because of the insufficient bearing force of each bone and its pivot joint point, resulting in the above-mentioned bones Folded, bent, deformed or even broken, the user cannot continue to use the umbrella to cover the wind and rain in the severe wind and rain environment, and suffers from the predicament of being hit by the wind and getting wet by the rain
