[0002] An umbrella is one of the indispensable tools in daily life. The common umbrellas on the market are mainly divided into straight-rib umbrellas and folding umbrellas. Among them, folding umbrellas are more popular among the public due to their small size and easy portability. In recent years, with the enhancement of sun protection awareness, as well as factors such as complex and changeable climate and uncertain weather, more and more people carry umbrellas with them. Although there are a variety of folding umbrellas on the market, most of them are not light and portable enough, and they also need to occupy a certain space when put into a carry-on bag.

[0003] As Figure 4 shown, when the traditional umbrella ribs are closed, they adopt a structure of folding each other. After the umbrella ribs are stored, they will stack together with a certain thickness. When the umbrella is closed, the umbrella ribs overlap and interfere with each other, making the volume of the umbrella larger after closing, not light and portable enough, occupying a large amount of space, and being inconvenient to put into a carry-on bag. Summary of the Invention

[0004] To solve the problems raised in the above background art, the utility model provides a lightweight and ultra-thin umbrella rib. The auxiliary rib utilizes the side space and is misaligned and folded on the side of the inner main rib; the thickness of the umbrella ribs after closing the umbrella is not increased; one end of the middle main rib is embedded in the joint and folded on the side of the tail rib. Two umbrella ribs are on the same plane and only occupy the space of one umbrella rib in terms of thickness, realizing overall lightness and portability, reducing the thickness of the umbrella ribs stacked together after storage, achieving the effect of volume contraction after the umbrella is stored, being convenient to put into a carry-on bag, and reducing the occupied space.

[0005] To achieve the above object, the utility model provides the following technical solution: a lightweight and ultra-thin umbrella rib, including a middle rod, main umbrella ribs and auxiliary ribs. An upper nest and a lower nest are arranged on the middle rod. The main umbrella ribs are composed of an inner main rib, a middle main rib and a tail rib. One end of the inner main rib is fixed on the upper nest, and the other end of the inner main rib is joined with the middle main rib. One end of the auxiliary rib is fixed on the lower nest, and the other end of the auxiliary rib is misaligned and hinged with the side of the inner main rib; the middle main rib and the tail rib are misaligned and hinged with each other through a joint.

[0006] As a preferred solution, the joint is a misaligned folding joint.

[0007] As a preferred solution, in the closed state of the umbrella ribs, one end of the middle main rib is embedded in the joint and misaligned and folded on the side of the tail rib; the middle main rib and the tail rib are on the same horizontal line.

[0008] As a preferred solution, in the closed state of the umbrella ribs, the auxiliary rib utilizes the side space and is misaligned and folded on the side of the inner main rib, and the auxiliary rib and the inner main rib are on the same horizontal line.

[0009] As a preferred solution, the middle rod is an octagonal middle rod, and the cross section of the middle rod is an octagon.

[0010] As a preferred embodiment, a steel wire rope connected to one end of the middle main bone is provided on the hinged end of the auxiliary bone and the inner main bone, and a steel wire rope connected to the joint is provided on the joint end of the inner main bone and the middle main bone.

[0011] Compared with the prior art, the beneficial effects of the utility model are:

[0012] The utility model articulates the auxiliary bones with the inner main bones at the side in an offset manner; when the ribs are folded, the auxiliary bones utilize the side space to be offset and folded on the side of the inner main bones, and the auxiliary bones and the inner main bones are located on the same horizontal plane; the thickness of the ribs after the umbrella is folded is not increased; one end of the middle main bone is embedded in the joint and folded on the side of the coccyx, and the two ribs of the middle main bone and the coccyx are located on the same plane, parallel and not overlapping, so that the whole ribs appear very thin and small in size after the umbrella is folded; the thickness only occupies the space of one rib, so that the whole umbrella is light and portable; the ribs are stacked together after being folded to reduce the thickness, so as to achieve the effect of shrinking the volume of the umbrella after being folded, so that it is easy to put into a carry-on bag and reduces the space occupied.

[0013] The ribs are folded in an offset manner, and the side space can be effectively utilized when the ribs are folded. After folding, the thickness of two ribs is only one rib, which directly reduces the volume of the ribs after storage and can be easily put into a pocket.

An upper nest 2 and a lower nest 3 are provided on the middle rod 1. The main umbrella rib 4 is composed of an inner main rib 4a, a middle main rib 4b and a tail rib 4c. One end of the inner main rib 4a is fixed on the upper nest 2, and the other end of the inner main rib 4a is joined to the middle main rib 4b. One end of the auxiliary rib 5 is fixed on the lower nest 3, and the other end of the auxiliary rib 5 is articulated with the side surface of the inner main rib 4a in a staggered manner. When the umbrella rib is in the closed state, the auxiliary rib 5 is folded in a staggered manner in the side space on the side surface of the inner main rib 4a, and the auxiliary rib 5 and the inner main rib 4a are on the same horizontal line, without increasing the thickness of the closed umbrella. The middle main rib 4b and the tail rib 4c are articulated with each other through a joint 6 in a staggered manner. The joint 6 is a staggered folding joint. When the umbrella rib is in the closed state, one end of the middle main rib 4b is inserted into the joint 6 and folded on the side of the tail rib 4c. The middle main rib 4b and the tail rib 4c are on the same horizontal line. In terms of thickness, it only occupies the space of one umbrella rib, parallel and non-overlapping, so that the whole umbrella rib looks very slender and thin after being closed, with a small volume, light and portable. After the umbrella ribs are stored, they are stacked together to reduce the thickness, which is convenient to be put into a carry-on bag and reduces the occupied space.

[0032] In this embodiment, the middle rod 1 is an octagonal middle rod, and the cross-section of the middle rod 1 is octagonal.

[0033] In this embodiment, a steel wire pull rope connected to one end of the middle main rib 4b is provided at the articulated end of the auxiliary rib 5 and the side surface of the inner main rib 4a, and a steel wire pull rope connected to the joint 6 is provided at the joint end of the inner main rib 4a and the middle main rib 4b.

[0034] As Figure 10 shown, the auxiliary rib 5 adopts a double-branch rib structure design.

[0035] The working principle and usage process of the present utility model: When the present utility model is in use, through the staggered joint of the umbrella ribs, the effect of volume contraction after the umbrella is stored is achieved. As Figure 3 shown, the auxiliary rib 5 is articulated with the side surface of the inner main rib 4a. When the umbrella ribs are in the closed state as shown in Figure 6 and Figure 7 shown, the auxiliary rib 5 uses the side space and is folded in a staggered manner on the side surface of the inner main rib 4a without increasing the thickness of the closed umbrella. When the umbrella ribs are opened, the middle main rib 4b and the tail rib 4c are articulated with each other through the connected joint 6 in a staggered manner, and the state is as shown in Figure 8 shown, and the middle main rib 4b and the tail rib 4c are joined in a staggered manner. After the umbrella ribs are closed as shown in Figure 9 shown, one end of the middle main rib 4b is inserted into the joint 6 and folded on the side of the tail rib 4c. The two umbrella ribs are on the same plane, parallel and non-overlapping, so that the whole umbrella rib looks very slender and thin after being closed, with a small volume. In terms of thickness, it only occupies the space of one umbrella rib, light and portable. After the umbrella ribs are stored, they are stacked together to reduce the thickness, which is convenient to be put into a carry-on bag and reduces the occupied space.
