Abstract

PROBLEM TO BE SOLVED: To provide a two-stage folding upside-down umbrella with an automatic return capable of reducing wind resistance, avoiding damage / destruction due to complete turning over, and restoring a curved shape before turning inside out. A two-stage folding upside-down umbrella with automatic return includes a central rod 1, an umbrella frame 2, and a curve return device 3, and is installed on the umbrella frame 2 by using the curve return device 3 to provide an umbrella. When deploying the tension bone 21 and the flat bone 22 of the skeleton 2, the flat bone 22 limits the deployment distance of the tension bone 21, so that the tension bone 21 is curved and the umbrella bone is stretched. By utilizing the limitation of the inside-out distance when the skeleton 21 receives wind resistance and the elastic repositioning ability generated when the tension skeleton 21 is deployed, the wind resistance can be reduced or eliminated. When you do, you can automatically return to the original expanded state. [Selection diagram] Fig. 6

Description

The present invention relates to a two-stage folding upside-down umbrella with automatic return, and in particular, it utilizes the limitation of the inside-out distance when the tension frame of the umbrella bone receives wind resistance, and occurs when the tension frame is deployed. It relates to an umbrella that can automatically return to the original unfolded state when the wind resistance is reduced or extinguished by utilizing the elastic repositioning ability.

The umbrella bone of a general upside-down umbrella uses the elastic part provided on the tension bone of the umbrella bone to cause compression of the elastic part when the umbrella bone is deployed, so that the tension is increased according to the repositioning ability of the elastic part. By bending the bones in conjunction with each other, such means increase the installation cost of the elastic part and are not easy to assemble, which increases the overall cost, and after using the elastic part for a certain period of time, The effect will be lost due to elastic fatigue. Moreover, such means will cause damage or destruction due to inside out if the wind resistance is too high.

The main object of the present invention is to be installed on the umbrella frame by using a bending return device, and when the tension bone and the flat bone of the umbrella frame are deployed, the expansion distance of the tension bone is limited by the flat bone. Therefore, in addition to causing curvature, when receiving wind resistance, the wind resistance can be reduced by limiting the inside-out distance of the tension bone and utilizing the elastic repositioning ability generated when the tension bone is deployed. It is to provide a two-stage folding upside-down umbrella with automatic return that can automatically return to the original unfolded state when it is extinguished.

In order to achieve the above object, the two-stage folding upside-down umbrella with automatic return of the present invention includes a central rod, an umbrella frame, and a bending return device, and the bending return device is provided with a fastening portion and a position. It has a regulating member and a retaining portion, and the fastening portion and the retaining portion are projected between both ends of the second tension section of the umbrella frame, and the fastening portion faces the retaining portion.

When the umbrella frame is deployed and the first and second tension sections are formed in a curved shape, the tension bones interlock with the connecting bones. The flat bone is formed in a curved shape.

According to the present invention, when it is installed on the umbrella frame by using the bending return device and the tension bone and the flat bone of the umbrella frame are deployed, the deployment distance of the tension bone is limited by the flat bone. Utilizing the fact that the tension bone of the umbrella bone is curved, limiting the inside-out distance when the tension bone of the umbrella bone receives wind resistance, and the elastic repositioning ability generated when the tension bone is deployed. Therefore, when the wind resistance is reduced or extinguished, the original unfolded state can be automatically restored.
