[0027] In order to make the above-mentioned purposes, features and advantages of the utility model more obvious and easy to understand, the specific implementation methods of the utility model are described in detail below in conjunction with the accompanying drawings. In the following description, many specific details are set forth to facilitate a full understanding of the utility model. However, the utility model can be implemented in many other ways different from those described herein, and those skilled in the art can make similar improvements without violating the connotation of the utility model, so the utility model is not limited by the specific embodiments disclosed below.

[0028] It should be noted that when an element is referred to as being "fixed to" another element, it may be directly on the other element or there may also be a central element. When an element is considered to be "connected to" another element, it may be directly connected to the other element or there may be a central element at the same time. In contrast, when an element is referred to as being "directly on" another element, there is no intermediate element. The terms "vertical", "horizontal", "left", "right" and similar expressions used herein are for illustrative purposes only."

[0029] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as those commonly understood by those skilled in the art in the technical field of the present invention. The terms used herein in the specification of the present invention are only for the purpose of describing specific embodiments and are not intended to limit the present invention. The term "and / or" used herein includes any and all combinations of one or more related listed items.

[0030] As shown Figures 1 to 13 A curved umbrella-shaped folding umbrella, characterized in that it includes a main rib including a front section 11 and a rear section 12. The front section 11 and the rear section 12 are provided with a front communication hole and a rear communication hole at their ends. The front section 11 and the rear section 12 are connected by a front and rear pin 2 at the positions of the front communication hole and the rear communication hole. The cross-section of the main rib is U-shaped, and the front section 11 and the rear section 12 partially overlap at the positions of the front communication hole and the rear communication hole.

[0031] The main rib has a front section 11 and a rear section 12 riveted together, which has high rigidity and will not affect the normal use of the umbrella. However, during the unfolding process, at the rivet connection position, a certain rotation will occur between the front section 11 and the rear section 12, so that the overall main rib is in a certain arc shape, making the overall umbrella rib of the umbrella have a certain arc shape, thus improving the overall aesthetics of the umbrella.

[0032] Similarly, at this time, the main rib can be set to three sections, and the three sections are riveted together by rivets. Specifically, a middle section 13 is further provided between the front section 11 and the rear section 12. The two ends of the middle section 13 are provided with a first middle hole and a second middle hole. The middle section 13 is connected to the front communication hole of the front section 11 through a first pin 21 at the position of the first middle hole, and the middle section 13 is connected to the rear communication hole of the rear section 12 through a second pin 22 at the position of the second middle hole. The middle section 13 partially overlaps at the connection positions with the front end and the rear end.

[0033] In order to prevent the angle from being too large when the sections rotate relative to each other, which may affect the normal use of the umbrella, the U-shaped openings of the front section 11 and the rear section 12 face the same side, or the U-shaped openings of the front section 11, the middle section 13 and the rear section 12 face the same side. The U-shaped openings face the same side and partially overlap at the connection positions. In this way, when rotation occurs at the riveted joints of each section, it can be limited by the ends, avoiding the problem of poor stability of the main rib caused by too large a freely rotatable angle.

[0034] In one embodiment, as shown Figure 1 、 Figure 2 、 Figure 9 、 Figure 10 At this time, the main rib is an inner main rib. One end of the inner main rib is rotatably connected to the upper nest, and the other end of the inner main rib is rotatably connected to the middle main tube. A support rib 6 is provided on the lower side of the inner main rib. One end of the support rib 6 is rotatably connected to the lower nest, and the other end of the support rib 6 is rotatably connected to the inner main rib. The structure of the support rib 6, as well as the upper nest and the lower nest, adopt the solutions in the prior art. At this time, the inner main rib is closer to the umbrella support side. The support rib 6 and the inner side of the inner main rib are riveted together by a rivet, and rotation can occur between the two, forming a support for the inner main rib and being used to retract the inner main rib when the umbrella is closed.

[0035] At this time, when the main bone is the front section 11 and the rear section 12, one end of the branch bone 6 is riveted through the front and rear pins 2 at the positions of the front communication hole and the rear communication hole of the front end and the rear section 12. At this time, the branch bone 6, the front section 11 and the rear section 12 of the inner main bone are riveted by one rivet. In this way, the branch bone 6 can provide a certain support for the front section 11 and the rear section 12 of the inner main bone at the same time. After the umbrella is unfolded, the front section 11 and the rear section 12 of the inner main bone can rotate at a small angle at the positions of the front and rear pins 2, so that the inner main bone as a whole has a certain arc.

[0036] In one embodiment, as Figure 3 , Figure 4 , Figure 11 , Figure 12 shown, at this time, the main bone is the inner main bone, and when the main bone is the front section 11, the middle section 13, and the rear section 12, an inner pin hole is provided at the middle position of the middle section 13. The branch bone 6 is riveted to the middle section 13 through the inner rivet 3 at the position of the inner pin hole. At this time, the inner main tube is a three-section structure, obtained by riveting the front section 11, the middle section 13, and the rear section 12. An inner pin hole is provided at the middle position of the middle section 13, and the branch bone 6 is riveted to the middle section 13 at the position of the inner pin hole, so as to realize the riveting of the branch bone 6 and the inner main bone. Since small-angle rotation can occur between the front section 11, the middle section 13, and the rear section 12, therefore, after the branch bone 6 provides support for the middle section 13, it can provide a certain support for the inner main bone as a whole, and during the process of folding the umbrella, it can provide a certain pulling force. Finally, for the three-section front section 11, middle section 13, and rear section 12, after the umbrella is unfolded, the umbrella ribs can form a certain arc, causing the overall arc of the umbrella to change.

[0037] In one embodiment, as Figure 5 , Figure 6 , Figure 9 , Figure 10 shown, at this time, the main bone is the middle main bone, and when the main bone is the front section 11 and the rear section 12, the main bone is provided with a limiting hole, and the limiting hole is the front communication hole and the rear communication hole. A middle connecting bone 4 is provided on the inner side of the U-shaped opening of the main bone, and the middle section 13 of the middle connecting bone 4 is clamped at the lower side position of the front and rear pins 2. At this time, the middle main tube is formed by riveting the two-section front section 11 and the rear section 12. In this way, during use, the front section 11 and the rear section 12 of the middle main bone can rotate at a small angle, so that the middle main bone as a whole has a certain arc. During use, the middle main bone as a whole has a certain arc. At the same time, for the connecting bone corresponding to the middle main bone, clamping the middle of the connecting bone at the lower side position of the front and rear pins 2 can omit the pin holes and pins required for the original connecting bone positioning. After setting the connecting bone, it can provide the stability of the umbrella ribs at the position of the middle main bone.

[0038] In one embodiment, as Figure 7 , Figure 8 ,Figure 11 , Figure 12 As shown, at this time, the main bone is the middle main bone. When the main bone is the front section 11, the middle section 13, and the rear section 12, the main bone is provided with a limiting hole. When the limiting hole is the middle pin hole 5 provided at the middle position of the middle section 13, a middle pin 51 is provided in the middle pin hole 5, and the middle connecting bone 4 is clamped at the lower side position of the middle pin 51. At this time, in order to limit the connecting bone, it is necessary to provide a middle pin hole 5 and a corresponding middle pin 51 at the middle position of the middle section 13, so that the middle connecting bone 4 is clamped at the lower side of the middle pin 51 to form a middle connecting bone 4 corresponding to the middle main bone. The three-section middle main bone will form a certain arc after being unfolded, so that the overall umbrella surface is arc-shaped.

[0039] In the overall structure of the umbrella, both the inner main bone and the middle main bone can adopt the two-section front section 11 and rear section 12 structure, or the three-section front section 11, middle section 13, and rear section 12 structure. Similarly, multiple middle main bones can be provided, and the two-section front section 11 and rear section 12 structure, or the three-section front section 11, middle section 13, and rear section 12 structure can also be continued to be adopted. In this way, according to actual needs, the inner main bone can be designed as a two-section structure or a three-section structure, and the heavy main bone can be designed as a two-section structure or a three-section structure to meet different requirements.

[0040] The technical features of the above-described embodiments can be combined arbitrarily. For the sake of brevity of description, not all possible combinations of the technical features in the above-described embodiments are described. However, as long as there is no contradiction in the combination of these technical features, it should be considered as within the scope described in this specification.

[0041] The above-described embodiments only represent several implementation manners of the present invention. The description is relatively specific and detailed, but it should not be construed as a limitation on the scope of the utility model patent. It should be noted that for those of ordinary skill in the art, without departing from the concept of the present invention, several modifications and improvements can still be made, and these all belong to the protection scope of the present invention. Therefore, the protection scope of the utility model patent should be subject to the appended claims.
