Description

Windproof umbrella with auxiliary ribs

The utility model belongs to umbrellas, in particular to a windproof umbrella with auxiliary ribs.

Umbrella is a kind of utensil that people often use to shade and avoid rain. As shown in FIG. 1 , a conventional umbrella includes an umbrella stand 10 that can be folded and unfolded and an umbrella cloth 14 covered on the umbrella stand 10, wherein the umbrella stand 10 is provided with an upper ring nest 111 at the upper end of an umbrella pole 11. The outer periphery of the upper ring nest 111 is evenly distributed with several main umbrella ribs 12, and a lower ring nest 112 that can move up and down along the umbrella rod 11 is set on the umbrella pole 11, and the outer periphery of the lower ring nest 112 is evenly distributed with a number of pivots. The side umbrella rib 13, the other end of the side umbrella rib 13 is pivotally arranged at the middle section of the main umbrella pole 11, and the umbrella cloth 14 is covered and fixed on the main umbrella rib 12. After the above components are combined, a collapsible and unfoldable umbrella is formed.

But, as shown in Figure 2, the above-mentioned conventional umbrella is because of its umbrella stand 10 only with a few side ribs 13 that are pivotally arranged at the lower ring nest 112 of the umbrella pole 11 to support the middle position of the main rib 12 to expand the umbrella cloth 14 , and the outer half of each main rib 12 does not have any auxiliary supporting structure, so the overall umbrella frame structure cannot form a better strength. And when the umbrella is unfolded and used, if it encounters a strong wind, its main umbrella rib is easy to reverse reversely, causing the umbrella cloth to fail to unfold and present a proper blocking surface to shade the sun and avoid rain. What's more, the main rib of the parachute may be flipped in reverse and cause damage to the parachute.

The purpose of the utility model is to provide a windproof umbrella with auxiliary ribs which improves the structural strength of the umbrella, enhances the wind resistance of the umbrella, and prevents reverse flipping.

The utility model comprises an umbrella frame composed of an umbrella pole, several main umbrella ribs, several side umbrella ribs, and several auxiliary umbrella ribs, and an umbrella cloth covering the umbrella frame; At the ring nest, each side rib is pivotally arranged between the lower ring nest that can move up and down on the umbrella pole and the middle position of the main rib; an auxiliary ring that can move up and down along the umbrella pole is set on the umbrella pole below the upper ring nest Nest, the auxiliary rib is slightly shorter than the main rib, and the two ends of the auxiliary rib are respectively pivotally set on the auxiliary ring nest and fixed at the end of the main rib; the umbrella cloth is covered on the main rib that supports and unfolds it.

in:

A positioning sleeve is arranged at the end of the auxiliary rib to fix it on the main rib.

An elastic element and a positioning ring fixed on the umbrella pole are sheathed on the umbrella pole below the auxiliary ring nest.

Because the utility model comprises an umbrella stand made up of an umbrella pole, several main umbrella ribs, several side umbrella ribs, and several auxiliary umbrella ribs, and an umbrella cloth covering the umbrella stand; At the upper ring nest, the ribs on each side are respectively pivoted between the lower ring nest and the middle section of the main rib; on the umbrella pole below the upper ring nest, an auxiliary ring nest that can move up and down along the umbrella pole is set, and the auxiliary ribs are slightly Shorter than the main rib, the two ends of the auxiliary rib are respectively pivotally arranged on the auxiliary ring nest and fixed at the end of the main rib; the umbrella cloth is covered on the main rib which supports and unfolds it. When the umbrella is unfolded and used, the umbrella frame will form a cohesive force toward the center with the auxiliary rib shorter than the main rib, and the end of the main rib will be slightly lowered, so that it can effectively strengthen the strength of the umbrella structure, and To improve the wind resistance of the umbrella, when the utility model encounters a strong wind, it can effectively avoid the reverse flip due to the strong wind, so as to achieve the purpose of the utility model.

Below in conjunction with accompanying drawing, the utility model is set forth in further detail.

As shown in FIG. 3 , the utility model includes a set of expandable and collapsible umbrella stands 2 and an umbrella cloth 3 covered on the umbrella stands 2 . Umbrella cloth 3 can be simple plane cloth body, also can be as shown in Figure 4, is the composite type cloth body with ventilation effect. The umbrella stand 2 is composed of an umbrella pole 20, several main umbrella ribs 21, several side umbrella ribs 22 and other components. Wherein the upper end of the umbrella pole 20 is provided with an upper ring nest 201 . A lower ring nest 202 is sleeved on the umbrella pole 20 and can move up and down along the umbrella pole 20 , and a handle for the user to hold is provided at the lower end of the umbrella pole 20 . Both the main ribs 21 and the side ribs 22 are elongated bodies made of highly elastic materials such as fibers. One end of each main umbrella rib 21 is pivotally arranged on the upper ring nest 201 ; The umbrella cloth 3 is covered on the main umbrella rib 21, and the umbrella cloth 3 is fixed on the main umbrella rib 21 with thin wires.

The main design of the utility model is the strengthened design carried out for the umbrella stand 2. As shown in Figure 3, Figure 4, and Figure 5, an auxiliary ring nest 23 that can move up and down along the umbrella pole 20 is set between the upper ring nest 201 and the lower ring nest 202 of the umbrella pole 20, and on the auxiliary ring nest 23 Several auxiliary ribs 24 corresponding to the number of main ribs 21 are pivotally arranged. The length of the auxiliary rib 24 is slightly shorter than the length of the main rib 21 . The auxiliary ribs 24 are also long strips made of highly elastic materials such as fibers. The other end of the auxiliary rib 24 is fixed on the outer end of the main rib 21 , and is fixed on the main rib 21 by a positioning sleeve 27 . An elastic element 25 and a positioning ring 26 fixed on the umbrella pole 20 can also be sleeved on the umbrella pole 20 below the auxiliary ring nest 23 . The positioning ring 26 pushes against the limit position under the elastic element 25 , so that the auxiliary ring nest 23 is more likely to move upward along the umbrella pole 26 under the push of the elastic force of the elastic element 25 .

As shown in Figures 5 and 6, when the umbrella is unfolded for use, push up the lower ring nest 202 to position above the umbrella pole 20, so that the side ribs 22 support the main ribs 21 to unfold the umbrella cloth 3. At this time, the ends of the auxiliary ribs 24 extend outward together with the main ribs 21 , and the auxiliary ring nest 23 sleeved on the umbrella pole 20 moves up against the bottom surface of the upper ring nest 201 under the elastic force of the elastic element 25 . Since the auxiliary rib 24 is shorter than the main rib 21, the auxiliary rib 24 exerts a pulling force relative to the end of the main rib 21, so that the end of the main rib 21 slightly presses down, so that the entire umbrella frame 2 structure has a direction toward the center. The cohesion of the direction can effectively strengthen the structural strength of the umbrella and improve the wind resistance of the umbrella.
