Description

[Technical Field]

[0001] The present invention relates to the technical field of umbrellas, and more particularly to a single-piece umbrella cloth and a folding umbrella that are applicable to folding umbrellas. [Background technology]

[0002] Due to their portability, folding umbrellas are widely used in everyday travel. As the core functional component of a folding umbrella, the umbrella fabric's structural design directly affects the umbrella's waterproofness, durability, processing efficiency, and user experience. Currently, mainstream folding umbrella fabrics on the market generally adopt a "multiple small fabric joining" structure. That is, based on the radial shape of the unfolded umbrella surface, several small fan-shaped or triangular fabric pieces are first cut, and then the edges of each small fabric piece are joined in sequence by sewing to finally form a complete umbrella fabric structure. The joined umbrella fabric is then fastened to the umbrella ribs.

[0003] However, this multi-joint umbrella fabric has obvious technical deficiencies.

[0004] The manufacturing process is complex, requiring multiple steps such as "cutting (dividing) the base fabric - edge processing - multiple alignments - sequential sewing." Not only does it require high cutting precision and high degree of alignment of the joints (misaligned joints will cause the umbrella surface to unfold unevenly), it also requires a lot of manual labor, which reduces production efficiency and also results in some waste of scraps when cutting the fabric into sections, increasing material costs.

[0005] Low structural durability. The fabric fibers at the seams are cut by cutting, and the sewing threads are subject to the tensile force and wind and rain when the umbrella is unfolded over a long period of time, which can easily cause problems such as thread wear and tearing of the fabric, shortening the service life of the umbrella fabric. Especially when the umbrella is frequently opened and closed, the speed of seam wear is faster.

[0006] Poor appearance: The seams formed by multiple joining destroy the integrity of the umbrella fabric (especially the pattern) and affect the aesthetic appearance.

[0007] For these reasons, there is room for improvement in the fabrics of conventional folding umbrellas. Summary of the Invention

[0008] The technical problem solved by the present disclosure is to provide an improved umbrella cloth and a folding umbrella having the same.

[0009] The technical solution adopted by this invention to solve the technical problem is a single-piece umbrella cloth applied to a folding umbrella, which is formed from a single piece of cloth, and the underside of the umbrella cloth is arranged with compression strips that fit the umbrella rib structure to connect the umbrella ribs.

[0010] In the single-piece umbrella cloth applied to the above-mentioned folding umbrella, a protective band is covered along the edge of the umbrella cloth.

[0011] In the single-piece umbrella cloth applied to the above-mentioned folding umbrella, the pressure strips are sewn to the umbrella cloth with transparent thread.

[0012] In the single-piece umbrella cloth applied to the above-mentioned folding umbrella, a through hole is provided in the center of the umbrella cloth for fixing the center rod assembly of the umbrella rib.

[0013] A folding umbrella including an umbrella rib, the folding umbrella further including the umbrella cloth according to any one of the above items, the umbrella cloth being laid on the umbrella rib.

[0014] In the above-mentioned folding umbrella, the ribs are connected to the pressure rods and fixed by ropes. [Effects of the Invention]

[0015] Compared with the conventional multi-joint umbrella fabric, the folding umbrella fabric with the "one-piece integral molding + bottom pressure strip connection" structure described in this application can solve the above technical deficiencies in a targeted way and has the following significant beneficial effects:

[0016] The processing process is greatly simplified, reducing production costs. The complicated process of "cutting, dividing, and then sewing multiple pieces together" required for conventional umbrella fabrics is eliminated. Instead, a single piece of base fabric is molded in one go (e.g., cutting the entire fabric to fit the umbrella surface size directly), and then stitching pressure strips to the underside according to the distribution of the umbrella ribs. On the one hand, process difficulties such as cutting misalignment and joining alignment are eliminated, reducing production failure rates and improving production efficiency. On the other hand, waste from cut-and-sewn scraps is avoided, while manual labor input is reduced, significantly reducing labor and material costs.

[0017] The durability of the entire umbrella fabric is enhanced, extending its service life. The one-piece, one-piece construction ensures the integrity of the umbrella fabric fibers, eliminating the problem of fiber breakage at the seams, and improving the overall tensile and tear resistance of the umbrella fabric.

[0018] Optimized appearance and user experience. The single piece of fabric has no seams, and the outer pattern of the umbrella fabric is clean and unified, creating a more concise and beautiful visual effect, particularly suited to personalized printing designs (there are no seams that disrupt the integrity of the pattern). Furthermore, the one-piece fabric has higher flatness and better waterproofing. When the fabric is connected to the ribs by pressure strips, there is no friction or jamming caused by thickness variations at the seams. This makes the opening and closing of the folding umbrella smoother and lighter, improving the user's experience. [Brief explanation of the drawings]

[0021] In order to make the objectives, technical means and advantages of the embodiments of the present invention clearer, the technical means of the embodiments of the present invention will be clearly and completely described below in combination with the drawings of the embodiments of the present invention. Obviously, the described embodiments are only some embodiments of the present invention, but not all embodiments.

[0022] Based on the described embodiments of the present invention, all other embodiments that can be obtained by those skilled in the art without requiring creative work fall within the scope of protection of the present invention. Unless otherwise defined, technical or scientific terms used in this disclosure shall have ordinary meanings that can be understood by those with ordinary skills in the field to which the present invention belongs.

Terms such as "top," "bottom," "left," and "right" are used only to denote relative positions, and if the absolute positions of the objects described change, the relative positions may change accordingly.

[0024] 1 and 2, an umbrella cloth applied to a folding umbrella is shown. The umbrella cloth 1 is formed from a single piece of cloth, and on the underside of the umbrella cloth 1, compression strips 2 are arranged to fit the umbrella rib structure in order to connect the umbrella ribs.

[0025] For example, a suitable umbrella fabric 1 substrate, such as 190T high-density nylon fabric, is selected, and the substrate is cut using a CNC laser cutting machine based on the unfolded size of the umbrella surface. During the cutting process, the edges of the umbrella fabric 1 are smooth and burr-free, and the entire umbrella fabric 1 is a single piece with no joints, meeting the requirements for forming a single piece of fabric. The single-piece umbrella fabric of this embodiment can be used in products such as everyday umbrellas for wind and rain protection, parasols for personal sun protection, and parasols for car windshields.

[0026] Fabric strips are used as the pressure strips 2. The pressure strips 2 extend from the center of the umbrella cloth 1 to its edge and have a certain width. For example, by selecting a polyester-cotton blend edge covering strip, which has high tensile strength and good sewing adaptability, the connection strength with the umbrella ribs can be ensured and the umbrella can be folded synchronously with the umbrella cloth 1 without wrinkling or breaking. Based on the structure of the folding umbrella ribs, the placement path of the pressure strips 2 is planned on the underside of the umbrella cloth 1 (i.e., the inner surface facing the user when the umbrella is open and in use). Each pressure strip 2 is arranged in a radial direction from the center of the umbrella's top to the edge of the umbrella cloth 1, perfectly matching the orientation of the corresponding umbrella rib.

[0027] In some embodiments, the pressure strips 2 are sewn to the umbrella cloth 1 with transparent thread. Nylon transparent thread can be selected, with a wire diameter of approximately 0.2 mm. Threads made of this material are almost completely transparent and can blend in highly with the colors of the umbrella cloth 1 and pressure strips 2. Whether the umbrella cloth 1 is a solid color or has a printed pattern, the sewing thread is difficult to observe from the top of the umbrella cloth 1 after sewing, which helps maintain a complete and neat visual effect on the surface of the umbrella cloth 1. This solves the problem of traditional transparent sewing threads disrupting the integrity of the pattern when sewing small pieces of fabric together, resulting in an abrupt appearance, and is particularly suitable for folding umbrellas, which require a high level of visual impact.

[0028] In some embodiments, the umbrella cloth 1 is covered with a protective strip 3 along the edge thereof.

[0029] Considering the issue of the edges of the folding umbrella fabric 1 being prone to wear and snagging, the protective strap 3 must simultaneously meet three core requirements: protection, flexibility, and adaptability to folding. A polyester-cotton blend edge covering strap can be selected. This material combines the high abrasion resistance of polyester with the flexibility of cotton (no creases remain even when folded 180 degrees). It also works well with the base material (nylon) of the umbrella fabric 1 and the pressure strip 2 (polyester-cotton blend), preventing the materials from peeling off after sewing.

[0030] The edges of the laser-cut umbrella cloth 1 are smooth, but contain fine fiber whiskers. The edges can be hot-pressed with a heat gun to prevent the threads from coming apart during subsequent use. To ensure the protective strip 3 is accurately positioned, a coating reference line is marked along the edge of the umbrella cloth 1. The protective strip 3 is folded in half lengthwise to form a U-shaped groove, and the edge of the umbrella cloth 1 is completely embedded in the U-shaped groove of the protective strip 3. During the coating process, the edges of the protective strip 3 and the umbrella cloth 1 are tightly attached to each other without any wrinkles or misalignment, ensuring that the edges are flat after coating. The two are then sewn together.

[0031] In this embodiment, the design of the protective band 3 covering the edge, based on the single-piece molding and the connection of the umbrella ribs with the pressure strip 2, further solves the problem that the edge of the umbrella cloth 1 is easily worn and caught, and greatly improves the service life and user experience of the folding umbrella.

[0032] In some embodiments, the umbrella cloth 1 has a through hole 4 at the center for fixing the shaft assembly of the umbrella bone.

[0033] A hole 4 is provided at the geometric center of a piece of umbrella cloth 1. The top of the pole assembly passes upward from the underside of the umbrella cloth 1 through the hole 4, and the umbrella top seat is inserted from the top of the umbrella cloth 1 onto the pole. The center of the umbrella cloth 1 is a stress concentration area when the umbrella is opened and closed. Repeated force can easily tear the fibers around the edge of the hole 4, so reinforcement is required. After the hole 4 is formed by laser cutting, the edge of the hole 4 is hot-pressed into a ring shape with a heat gun to form a smooth, hard, reinforced ring edge. A circular nylon lining can be sewn around the hole 4 on the underside of the umbrella cloth 1. The lining distributes the local stress around the edge of the hole 4, ensuring that the pressure from the pole assembly is evenly transferred to the umbrella cloth 1 when it is fastened, preventing single-point tearing.

[0034] A folding umbrella including an umbrella rib is provided, and the folding umbrella further includes the umbrella cloth 1 according to any one of the above items, and the umbrella cloth 1 is laid on the umbrella rib.

[0035] In some embodiments, the ribs are connected to the crimps 2 and fixed by ropes.

[0036] Using CNC laser cutting, 190T nylon fabric is processed into a seamless circular umbrella fabric 1 in one go. The edges are sealed using a hot press. Strands 2 are sewn onto the underside of the umbrella fabric 1 along the radial direction of the six small ribs. The transparent thread blends in with the color of the umbrella fabric 1 and the stratum 2, making them difficult to observe. The stratum 2 is connected to the umbrella ribs by ropes. The ribs are folded three times. Each small rib contains three folded, extendable ribs. A small hole is generally formed in the inner rib closest to the center rod. The rope is sewn to the stratum 2 so that it passes through the small hole in the first rib, with a slight slack in length to avoid the connection becoming too tight and stiff. At the outer rib closest to the edge of the umbrella fabric 1, the rope is sewn to the stratum 2 around the outer rib, allowing the rib to slide through the rope. Therefore, by connecting the umbrella ribs with a rope, it is possible to avoid a connection that is too stiff and affects the smoothness of opening and closing the umbrella.

[0037] In consideration of problems such as complex processing (cutting and sewing in sections), poor durability (easy tearing at the joints), poor waterproofing (leaking at the joints), and a poor opening and closing experience, this application proposes a design for umbrella cloth 1 centered on one-piece molding, and has made a series of optimizations centered on suitability for folding umbrellas. By adopting one-piece umbrella cloth 1, a high-density waterproof base material is cut and molded in one go, and the inner surface is sewn with transparent thread pressure stripes 2, optimizing the appearance's concealment, solving the core defects of traditional joined umbrella cloth 1 and significantly improving the overall performance and user experience of the product.

[0038] The above is only a preferred embodiment of the present invention, and is not intended to limit the present invention. Those skilled in the art will appreciate that the present invention may have various modifications, combinations, and variations. Any modifications, equivalent replacements, improvements, etc. made within the scope of the idea and principle of the present invention shall be included in the scope of the claims of the present invention.
