Description

[Technical field]

[0001] The present invention relates to the field of umbrella accessories, and more particularly to a rib for preventing a folding umbrella from flapping. [Background technology]

[0002] There are many types of umbrellas in the prior art, including straight-rib umbrellas and folding umbrellas, and the folding umbrellas have appeared for the convenience of carrying.

[0003] As shown in FIG. 1, the ribs of a conventional folding umbrella generally include an inner rib 1', an inner supporting rib 2', a middle rib 3', a linking rib 4', an outer rib 5', and a pulling rib 6'. Here, the middle rib 3' includes an inner connecting seat 31', an outer connecting seat 32', and a middle rib 33' whose inner and outer ends are connected to the inner connecting seat 31' and the outer connecting seat 32', respectively. The outer end of the inner rib 1' is pivotally attached to the center of the inner connecting seat 31', and the inner end of the inner supporting rib 2' is pivotally attached to the inner rib 1'. The interlocking rib 4' is pivotally attached to the middle of the inner rib 31', the inner end of the interlocking rib 4' is pivotally attached to the near inner end of the inner support rib 2', the outer end of the interlocking rib 4' is pivotally attached to the inner end of the inner connecting seat 31', the outer rib 5' includes a pivot seat 51' and an outer rib 52' whose inner end is connected to the pivot seat 51', the middle of the pivot seat 51' is pivotally attached to the outer end of the outer connecting seat 32', the inner end of the traction rib 6' is pivotally attached to the near inner end of the inner rib 1, and the outer end of the traction rib 6' is pivotally attached to the inner end of the pivot seat 51'. Here, the cross section of the middle rib 33' is generally as shown in Figures 2 to 5, and since the strength of the middle rib 33' in these configurations is low and easily deformed, when the folding umbrella is exposed to strong winds after being opened, the middle rib 33' is easily curved and deformed very seriously, causing the problem of the umbrella being turned inside out (i.e., the umbrella surface is inverted).

[0004] In view of the above problems, it is necessary to consider a folding umbrella rib that can prevent a folding umbrella from flipping over, which can avoid the problem of a folding umbrella being turned inside out when exposed to strong winds during use. Summary of the Invention [Problem to be solved by the invention]

[0005] The present invention aims to provide an umbrella rib for preventing an umbrella from turning over, which can avoid the problem that a folding umbrella is exposed to strong wind during use and turns inside out.

Means for Solving the Problem

[0006] To achieve the above object, the solution of the present invention includes an inner main rib, an inner support rib, a middle main rib, an interlocking rib, an outer main rib and a traction rib. The middle main rib includes an inner connection seat, an outer connection seat, and a middle rib with both inner and outer ends connected to the inner connection seat and the outer connection seat respectively. The outer end of the inner main rib is pivotally attached to the middle of the inner connection seat. The inner end of the inner support rib is pivotally attached to the middle of the inner main rib. The inner end of the interlocking rib is pivotally attached to the near inner end of the inner support rib. The outer end of the interlocking rib is pivotally attached to the inner end of the inner connection seat. The outer main rib includes a pivotal attachment seat and an outer rib with the inner end connected to the pivotal attachment seat. The middle of the pivotal attachment seat is pivotally attached to the outer end of the outer connection seat. The inner end of the traction rib is pivotally attached to the near inner end of the inner main rib. The outer end of the traction rib is pivotally attached to the inner end of the pivotal attachment seat. The cross-section of the middle rib呈s a "工" shape and includes an upper rib, a lower rib and a middle rib that are integrally formed. The upper and lower sides of the middle rib are connected to the upper rib and the lower rib respectively, and the width of the middle rib is smaller than the widths of the upper rib and the lower rib. It is an umbrella rib for preventing an umbrella from turning over.

[0007] A position regulating portion is provided on the upper side of the outer connection seat where the inner end of the pivotal attachment seat abuts. When the umbrella rib for preventing an umbrella from turning over is fully deployed, the inner end of the pivotal attachment seat abuts against the position regulating portion of the outer connection seat.

[0008] A position regulating sleeve sleeved on the traction rib is fitted in the middle of the middle main rib.

[0009] The interlocking rib has an integrally pressed structure, and the cross-section of the interlocking rib呈s a "U" shape.

[0010] The inner main rib has an integrally pressed structure, and the cross-section of the inner main rib呈s a "U" shape.

[0011] The inner support rib has an integrally pressed structure, and the cross-section of the inner support rib呈s a "U" shape.

[0012] Both the inner and outer ends of the middle rib are interposed between the inner connection seat and the outer connection seat respectively.

[0013] Both the inner and outer ends of the middle rib are adhered, riveted or welded to the inner connection seat and the outer connection seat respectively.

[0014] The inner end of the outer rib is interposed between the pivot seats.

[0015] The inner end of the outer rib is adhered, riveted or welded to the pivot seats.

[0016] When the present invention adopts the above technical solution, it has the following characteristics.

[0017] 1. The cross-section of the middle rib according to the present invention presents an "I" shape, which can make it difficult for the middle rib to generate bending deformation and torsional deformation. In this way, when the folding umbrella using the anti-turning umbrella rib according to the present invention is exposed to strong wind during use, the middle rib is not easily deformed and can effectively pull the outer main rib, thereby avoiding the problem that the multi-fold umbrella turns inside out.

[0018] 2. When the anti-turning umbrella rib of the folding umbrella according to the present invention is fully deployed, the inner end of the pivot seat abuts against the position regulating portion of the outer connection seat to regulate the rotation of the pivot seat, thereby avoiding the problem that the pivot seat rotates excessively and the folding umbrella turns inside out.

[0019] 3. The linkage rib according to the present invention has an integral press structure, and the cross-section of the linkage rib presents a "U" shape, so that the strength of the linkage rib is high and it is not easily subjected to tensile deformation. Furthermore, by ensuring the tensile action of the middle main rib by the linkage rib, the problem that the folding umbrella turns inside out is avoided.

[0021] In order to further explain the technical solution of the present invention, the present invention is described in detail below through specific examples.

[0022] As shown in FIGS. 6 to 12, the present invention includes an inner main rib 1, an inner support rib 2, a middle main rib 3, an interlocking rib 4, an outer main rib 5 and a traction rib 6. Here, the middle main rib 3 includes an inner connection seat 31, an outer connection seat 32, and a middle rib 33 with both inner and outer ends connected to the inner connection seat 31 and the outer connection seat 32 respectively.
