[0008] However, the disadvantage of this structural method is that it only considers the connection between the umbrella surface and the umbrella ribs, and ignores the structural form of the umbrella surface, so that the umbrella ribs are deformed under the influence of the umbrella surface, and the length of the umbrella ribs is not the same when opening and closing the umbrella. A formed structural defect cannot form a good umbrella shape
[0009] If the above-mentioned defects are to be overcome, an umbrella surface with good elasticity must be used, which will greatly increase the production cost of the umbrella, and the umbrella surface will cause other problems, such as not being glued, difficult to print, etc.
[0010] At the same time, in order to ensure the positioning of the umbrella surface, the integrated umbrella surface of this structure also needs to bond the umbrella surface and the umbrella ribs. As we all know, the bonding of metal and cloth is difficult to bond firmly, and it is often open In the operation of umbrellas and umbrellas, the firmness of the bonding will be greatly reduced, which is why the traditional umbrella surface is still combined with the umbrella ribs in the form of sewing; the simple thin ribs and the umbrella surface are bonded , after bonding, it still needs to be further cured to have a certain bonding fastness. Therefore, umbrellas with this structure still have many defects and are difficult to apply

Embodiment Construction
[0049] Below, in conjunction with the accompanying drawings, the specific implementation of the present invention will be described in detail. It should be noted that the specific description of the present invention is not intended as a specific limitation to the present invention. The specific implementation of the invention is equivalent.
[0050] figure 2 Shown is a schematic diagram of the yarn structure constituting a one-piece umbrella surface. Usually, the umbrella cover will be sliced and sewn into round, square and other shapes, no matter how it comes out, as the umbrella cloth for making the umbrella cover, its microstructure is as follows: figure 2 As shown, it is woven from yarns, specifically, a plurality of parallel warp a and vertical weft b, so that the umbrella cloth forms a grid-like structure, and each grid is composed of warp a , The square formed by the weft b, therefore, in different positions of the square, the deformation of the square caused by ...

The invention relates to an umbrella rib and umbrella fabric structure for a piece of umbrella fabric, which comprises main umbrella ribs and a one-piece umbrella fabric, wherein in the umbrella rib and umbrella fabric structure, a reference line is formed along a diagonal direction of a yarn square frame or a warp direction and a weft direction of yarns of the one-piece umbrella fabric in a center of a middle rod; at least four main umbrella ribs are arranged on the reference line or arranged symmetrically around the reference line; and the outer ends of the main umbrella ribs and the outer edge of the umbrella fabric are connected. The main umbrella ribs are arranged on the basis of the reference line, so that the umbrella ribs can be supported effectively according to a structural form of the one-piece umbrella fabric to form an arc-shaped ceiling formed after an umbrella is unfolded, namely an umbrella shape, and the umbrella ribs and the umbrella fabric can be folded effectively after the umbrella is folded.
Description
technical field [0001] The present invention relates to an umbrella rib structure, specifically an umbrella rib and umbrella surface structure for a piece of umbrella cover. Background technique [0002] The traditional umbrella cover is usually cut and sewed with a fast fabric, such as figure 1 As shown, the fabric is cut into a triangle A structure, and the side B of the triangle A is folded inward and then stitched to form a whole umbrella surface. [0003] This structure can splice the umbrella surface through the combination of multiple triangles A, and a piece of triangle A is clamped by two umbrella ribs to make an umbrella in the form of umbrella ribs, but the assembly of the umbrella surface and umbrella ribs of this structure is more complicated. A large amount of manual work is needed to sew, which greatly reduces the processing efficiency of the umbrella. The reason is that this umbrella surface is caused by the structure of the umbrella rib. [0004] For strai...
