Description

Technical Field

[0001] This invention relates to the field of daily life, and more specifically to an umbrella that is easy to store. Background Technology

[0002] Umbrellas are frequently used items in daily life. Currently, most umbrellas on the market have messy, wrinkled canopies when folded up after use, requiring manual tidying and rolling, which is neither neat nor aesthetically pleasing, and is tedious, time-consuming, and inconvenient.

[0003] For example, Chinese invention patent CN202011433546.8 discloses an umbrella that is easy to store and organize, including an umbrella canopy, an umbrella frame, umbrella ribs, an umbrella handle, convex folding guides, and concave folding guides. The convex and concave folding guides are set on the umbrella canopy. Distributed outwards from the center point of the umbrella, the umbrella canopy is supported by the umbrella frame, and the umbrella canopy branches to form individual canopies. Folding guides are set on different canopies to achieve a neat folding. The umbrella is a three-fold umbrella, with three folds: an inner layer, a middle layer, and an outer layer. The folding guides have two structures: a combination of convex and concave folding guides to form folding grooves. The folding guides are adhesive, can be fixed to the umbrella canopy, and are flexible and bendable. The concave folding guides have a recessed groove in the middle; when the groove faces upwards, the guide will fold upwards under pressure. The convex guide folding patch has a raised strip in the middle. When the raised strip points upwards, the patch will fold downwards under pressure. The convex and concave guide folding patches are made of PVC, PET, PP, PE, ABS, TPU, PU, ​​silicone, rubber, or EVA. The umbrella is a manual, automatic, or electric umbrella. The folding frame or ribs are three-fold, four-fold, or five-fold umbrellas. The umbrella also includes straps on the outside of the canopy for securing it.

[0004] This invention patent aims to solve the problem of difficult umbrella rolling to some extent, but its effect is not ideal. The patch creases cannot drive the entire umbrella surface to roll up neatly. The umbrella surface is still messy and wrinkled when rolling up. Moreover, the folded umbrella surface is scattered and cannot automatically move towards the rolling direction, causing a lot of trouble for users. Its convenience and practicality need to be improved.

[0005] In view of this, the inventors of this case conducted in-depth research on the above-mentioned problems, which led to the creation of this case. Summary of the Invention

[0006] The purpose of this invention is to provide an umbrella that can be rolled up efficiently, neatly, conveniently, and practically stored.

[0007] To achieve the above objectives, the present invention adopts the following technical solution: An umbrella that is easy to store includes an umbrella canopy, umbrella ribs supporting the umbrella canopy and extending radially along the umbrella canopy, and an umbrella pole supporting the umbrella ribs. The umbrella canopy is provided with a support piece that is arranged along the umbrella canopy and has a torsional strength higher than the umbrella canopy. The umbrella ribs include an inner section rib that supports the inner ring of the umbrella canopy and is connected to the umbrella pole, an outer section rib that supports the outer ring of the umbrella canopy, and a middle section rib that supports the middle part of the umbrella canopy and connects between the inner section rib and the outer section rib.

The umbrella canopy includes a plurality of umbrella slats located between adjacent umbrella ribs. Each umbrella slat has a connecting portion that connects to the umbrella ribs, the connecting portion including a first connecting portion corresponding to the first bend and a second connecting portion corresponding to the second bend. The umbrella slats have a support piece that is arranged between adjacent umbrella ribs and extends radially along the umbrella canopy. The umbrella canopy has radially extending warp creases, first weft creases located between adjacent ribs and corresponding to the first connecting portion, and second weft creases located between adjacent ribs and corresponding to the second connecting portion; the umbrella canopy has a stacking tilt direction where, after folding, it tilts and folds around the umbrella shaft in the same clockwise direction and rolls up towards the umbrella shaft; two adjacent ribs are defined as an upstream rib and a downstream rib along the stacking tilt direction, with the downstream rib located on the stacking tilt direction side of the upstream rib; the first weft crease includes a first upstream weft crease connecting the warp crease and the first bend of the upstream rib, and a first downstream weft crease connecting the warp crease and the first bend of the downstream rib; the second weft crease includes a second bend connecting the warp crease and the upstream rib.

The downstream edge segment is shorter than the upstream edge segment.The crease of the first downstream parallel is shorter than the crease of the first upstream parallel, and the crease of the second downstream parallel is shorter than the crease of the second upstream parallel.

[0008] The first connecting part is located in the inner segment of the bone, and the second connecting part is located in the outer segment of the bone.

[0009] The umbrella ribs are equipped with auxiliary springs to assist in the retraction and folding of the umbrella ribs.

[0010] The upper end of the umbrella shaft is provided with an upper umbrella socket that is rotatably connected to each inner rib, and a lower umbrella socket that is movably fitted onto the umbrella shaft for driving the extension and retraction of the umbrella ribs; the lower umbrella socket is located below the upper umbrella socket; each inner rib is equipped with a support rib, with the direction towards the center of the umbrella surface as the inner circle direction and the direction towards the outer circle of the umbrella surface as the outer circle direction; the outer end of the support rib is connected to both ends of the inner rib by a pivot, the inner end of the support rib is connected to the lower umbrella socket by a pivot, the inner end of the middle rib is connected to both ends of the support rib by a first transmission rod, and the inner end of the outer rib is connected to the inner rib by a pivot. The two ends of the bone are connected together by a second transmission rod; the first transmission rod, together with the inner segment bone, the middle segment bone and the supporting bone, forms a first parallelogram driving member, and the second transmission rod, together with the inner segment bone, the middle segment bone and the outer segment bone, forms a second parallelogram driving member; the inner segment bone has a first rotating connection part that is rotatably connected to the middle segment bone and a second rotating connection part that is rotatably connected to the supporting bone; one end of the auxiliary spring is connected to the part between the first rotating connection part and the second rotating connection part of the inner segment bone, and the other end of the auxiliary spring is connected to the supporting bone.

[0011] The angle between the warp crease and the angular midline of the umbrella panel is 0.1-10°.

[0012] The angle between the warp crease and the angular midline of the umbrella panel is 1-5°.

[0013] The first upstream latitude crease is parallel to the second upstream latitude crease, and the first downstream latitude crease is parallel to the second downstream latitude crease.

[0014] The second piece has a second bone side edge corresponding to the upstream bone and a second meridian side edge corresponding to the meridian fold. The second piece gradually bends in the stacking tilt direction from the second bone side edge to the second meridian side edge.

[0015] The first upstream latitude crease, upstream bone, longitude crease and umbrella shaft form a third support area for setting the support sheet, and the support sheet includes a third piece body set in the third support area.

[0016] There is a second gap between the third piece and the first piece, and the first upstream weft crease is located in the second gap. The second gap extends in the same direction as the first upstream weft crease.

[0017] The third piece has a third bone side edge corresponding to the upstream bone and a third meridian side edge corresponding to the meridian fold. The third piece gradually bends in the stacking tilt direction from the third bone side edge to the third meridian side edge.

[0018] The first downstream latitude crease, the second downstream latitude crease, the downstream rib, and the warp crease enclose a fourth support area for the support sheet, and the support sheet includes a fourth sheet body disposed within the fourth support area.

[0019] There is a third gap between the fourth piece and the first piece, and the warp crease extends along the third gap and passes through the third gap.

[0020] The fourth piece has a fourth bone side edge corresponding to the downstream bone and a fourth meridian side edge corresponding to the meridian fold. The fourth piece gradually bends in the stacking tilt direction from the fourth bone side edge to the fourth meridian side edge.

[0021] The support sheet is a resin sheet that is attached or printed on the lower surface of the umbrella canopy, and the thickness of the support sheet is 0.1-1mm.

[0022] The umbrella includes six or eight ribs and six or eight umbrella panels. Those skilled in the art should understand that the number of ribs and umbrella panels in this invention can be specifically set according to the specifications, load-bearing requirements and wind resistance requirements of the umbrella. In specific embodiments, the number of ribs and corresponding umbrella panels can be, for example, five, six, seven, eight, nine, ten, twelve or twenty-four, but the scope of protection of this invention is not limited to the above specific numbers.

[0023] After adopting the above technical solution, the umbrella of the present invention, which is convenient to store, breaks through the traditional umbrella structure. In actual use, the support piece has a higher torsional strength than the umbrella surface. When the umbrella is folded, the inner, middle and outer sections of each umbrella rib will fold and bend. With the assistance of the support piece, each umbrella piece of the umbrella surface will fold along the warp crease, the first weft crease and the second weft crease. Specifically, on the basis of the first and second pieces supporting the first and second support areas to be flat and torsion-resistant, the folding and bending of the upstream rib will cause the umbrella surface area between the warp crease and the upstream rib to fold along the first and second upstream weft creases. For example, the first bend will arch and bend towards the lower surface of the umbrella surface, and the second bend will arch and bend towards the upper surface of the umbrella surface. The first bend and the second bend will use the first and second connecting parts to make the umbrella surface area between the warp crease and the upstream rib follow and produce a corresponding folding action. Based on the torsional strength of the first and second umbrella panels, their torsional properties enhance the folding action of the canopy area between the warp crease and the upstream rib along the first and second upstream weft creases. Simultaneously, the canopy area between the warp crease and the downstream rib, driven by the combined folding action of the downstream rib and the warp crease, folds along the first and second downstream weft creases. Furthermore, supported by the first and second panels, the canopy areas between the warp crease and the upstream rib, and between the warp crease and the downstream rib, fold along the warp crease. This achieves efficient, smooth, and neat folding of each umbrella panel, arranging them around the umbrella shaft. Furthermore, because the warp crease is located between the angular midline of the umbrella panel and the downstream rib, and the downstream edge is shorter than the upstream edge, when each umbrella panel is folded, the area of ​​the umbrella surface enclosed by the warp crease, the second downstream weft crease, the downstream rib, and the downstream edge will pull the second support area to automatically tilt and fold in the stacking direction. This allows each folded umbrella panel to automatically roll up and converge towards the umbrella shaft, resulting in a neat and aesthetically pleasing roll. It eliminates the need for inefficient and tedious manual umbrella surface arrangement; if necessary, the user can simply tie it with cable ties. Compared to existing technologies, the umbrella of this invention offers advantages such as efficient and neat rolling, and convenient practicality. Attached Figure Description

Detailed Implementation

[0027] To further explain the technical solution of the present invention, a detailed description is provided below through specific embodiments.

[0028] The present invention provides a conveniently foldable umbrella, such as... Figure 1-13As shown, the umbrella includes an umbrella canopy 1, umbrella ribs 2 that support the umbrella canopy 1 and extend radially along the umbrella canopy 1, and an umbrella rod 3 that supports the umbrella ribs 2. The umbrella canopy 1 is provided with a support piece 4 that is arranged along the umbrella canopy 1 and has a higher torsional strength than the umbrella canopy 1. The umbrella ribs 2 include an inner section rib 21 that supports the inner ring of the umbrella canopy 1 and is connected to the umbrella rod 3, an outer section rib 22 that supports the outer ring of the umbrella canopy 1, and a middle section rib 23 that supports the middle part of the umbrella canopy 1 and connects between the inner section rib 21 and the outer section rib 22. There is a first bend 24 between the inner section rib 21 and the middle section rib 23, and a second bend 25 between the middle section rib 23 and the outer section rib 22. The umbrella canopy 1 includes a plurality of umbrella strips 11 located between adjacent umbrella ribs 2. Each umbrella strip 11 has a connection part that connects to the umbrella rib 2, and the connection part includes a part corresponding to the first bend 24. A first connecting portion 12 and a second connecting portion 13 corresponding to the second bend 25; the umbrella slab 11 has a warp crease 14 located between adjacent umbrella ribs 2 and extending radially along the umbrella surface 1, a first weft crease 15 located between adjacent umbrella ribs 2 and corresponding to the first connecting portion 12, and a second weft crease 16 located between adjacent umbrella ribs 2 and corresponding to the second connecting portion 13; the umbrella surface 1 has a stacking tilt direction that, after folding, tilts and folds around the umbrella shaft 3 in the same clockwise direction and rolls up towards the umbrella shaft 3; along the stacking tilt direction, two adjacent umbrella ribs 2 are defined as an upstream rib 210 and a downstream rib 220, with the downstream rib 220 located on the stacking tilt direction side of the upstream rib 210; the first weft crease 15 includes a connection between the warp crease 14 and the warp crease 15 and the first connecting portion 12. The first upstream latitude crease 151 between the first bends 24 of the lateral bone 210, and the first downstream latitude crease 152 connecting the warp crease 14 and the first bend 24 of the downstream bone 220; the second latitude crease 16 includes the second upstream latitude crease 161 connecting the warp crease 14 and the second bend 25 of the upstream bone 210, and the second downstream latitude crease 162 connecting the warp crease 14 and the second bend 25 of the downstream bone 220; the first upstream latitude crease 151 gradually slopes from the upstream bone 210 to the warp crease 14 towards the outer edge of the umbrella slab 11, and the first downstream latitude crease 152 gradually slopes from the downstream bone 220 to the warp crease 14 towards the outer edge of the umbrella slab 11, the first upstream latitude crease 151 gradually slopes from the downstream bone 220 to the warp crease 14 towards the outer edge of the umbrella slab 11, the first downstream latitude crease 152 gradually slopes from the downstream bone 220 to the warp crease 14 towards the outer edge of the umbrella slab 11, the first downstream latitude crease 152 gradually slopes from the downstream bone 220 to the warp crease 14 towards the outer edge of the umbrella slab 11, the first downstream latitude crease 152 gradually slopes from the downstream bone 220 to the warp crease 14 towards the outer edge of the umbrella slab 11, the first downstream latitude crease 151 ... The first upstream weft crease 151 and the first downstream weft crease 152 intersect at the warp crease 14; the second upstream weft crease 161 gradually slopes towards the outer edge of the umbrella slab 11 from the upstream rib 210 to the warp crease 14, and the second downstream weft crease 162 gradually slopes towards the outer edge of the umbrella slab 11 from the downstream rib 220 to the warp crease 14. The second upstream weft crease 161 and the second downstream weft crease 162 intersect at the warp crease 14, that is, the intersection of the first upstream weft crease 151 and the first downstream weft crease 152 at the warp crease 14 forms a sharp angle towards the outer edge of the umbrella surface 1, and the intersection of the second upstream weft crease 161 and the second downstream weft crease 162 at the warp crease 14 forms a sharp angle towards the outer edge of the umbrella surface 1.This structure allows the umbrella slab 11 to adapt to and follow the folding action of the umbrella ribs 2; when the first upstream weft crease 151 is parallel to the second upstream weft crease 161, and the first downstream weft crease 152 is parallel to the second downstream weft crease 162, the effect of the umbrella slab 11 adapting to and following the folding action of the umbrella ribs 2 will be enhanced. The first upstream weft crease 151, the second upstream weft crease 161, the upstream rib 210, and the warp crease 14 form a first support area 17 for the support piece 4. The second upstream weft crease 161, the upstream rib 210, the warp crease 14, and the outer edge of the umbrella sheet 11 form a second support area 18 for the support piece 4. The support piece 4 includes a first sheet 41 located in the first support area 17 and a second sheet 42 located in the second support area 18. A first gap 43 exists between the first sheet 41 and the second sheet 42. The second upstream weft crease 161 is located within the first gap 43. The first gap 43 extends in the same direction as the second upstream weft crease 161. The first gap 43 provides buffer space for folding of the umbrella sheet 1 at the second upstream weft crease 161. A buffer space can also be provided for the relative folding of the first piece 41 and the second piece 42 to ensure that the umbrella surface 1 folds smoothly. In order to further ensure that the umbrella surface 1 has a smooth folding space, the included angles of the support piece 4 and the warp crease 14 are all chamfered, specifically, they can be smooth arc chamfers. The warp crease 14 is located between the angular dividing line 5 of the umbrella piece 11 and the downstream umbrella rib 2. The outer edge of the umbrella piece 11 includes the upstream edge segment 111 located between the warp crease 14 and the upstream rib 210, and the downstream edge segment 112 located between the warp crease 14 and the downstream rib 220. The downstream edge segment 112 is shorter than the upstream edge segment 111. The first downstream weft crease 152 is shorter than the first upstream weft crease 151, and the second downstream weft crease 162 is shorter than the second upstream weft crease 161. In practical use, the support piece 4 has a higher torsional strength than the umbrella surface 1. When the umbrella is folded, the inner rib 21, middle rib 23, and outer rib 22 of each umbrella rib 2 will fold and bend. With the assistance of the support piece 4, each umbrella piece 11 of the umbrella surface 1 will fold along the warp crease 14, the first weft crease 15, and the second weft crease 16 of the umbrella piece 11. Specifically, based on the first support area 17 and the second support area 18 supported by the first piece 41 and the second piece 42 being flat and torsion-resistant, the upstream rib 210 The folding and bending will cause the area of ​​the umbrella surface 1 between the warp crease 14 and the upstream rib 210 to fold along the first upstream weft crease 151 and the second upstream weft crease 161. For example, with the direction towards the center of the umbrella surface 1 as the inner circle direction and the direction towards the outer circle of the umbrella surface 1 as the outer circle direction, the first bend 24 arches and bends towards the lower surface of the umbrella surface 1, causing the inner end of the first piece 41 supporting the umbrella piece 11 to arch and bend along the first upstream weft crease 151 towards the lower surface of the umbrella surface 1; the second bend 25 arches and bends towards the upper surface of the umbrella surface 1.The outer end of the first piece 41 supports the umbrella piece 11, which arches and bends along the second upstream weft crease 161 toward the upper surface of the umbrella surface 1. The first bend 24 and the second bend 25 will use the first connecting part 12 and the second connecting part 13 to make the area of ​​the umbrella surface 1 between the warp crease 14 and the upstream rib 210 follow and produce a corresponding folding action. Based on the torsional strength of the first piece 41 and the second piece 42, the first piece 41 and the second piece 42 utilize their torsional properties to enhance the folding action of the umbrella surface 1 area between the warp crease 14 and the upstream rib 210 along the first upstream weft crease 151 and the second upstream weft crease 161. Simultaneously, the umbrella surface 1 area between the warp crease 14 and the downstream rib 220, driven by the folding action of the downstream rib 220 combined with the folding action of the umbrella surface 1 area between the warp crease 14 and the upstream rib 210, will follow and fold along the first downstream weft crease 152 and the second downstream weft crease 162. Furthermore, supported by the first piece 41 and the second piece 42, the umbrella surface 1 areas between the warp crease 14 and the upstream rib 210 and between the warp crease 14 and the downstream rib 220 will fold along the warp crease 14. This achieves efficient, smooth, and neat folding and arrangement of each umbrella piece 11 around the umbrella pole 3. Furthermore, since the warp crease 14 is located between the angular dividing line 5 of the umbrella piece 11 and the downstream rib 2, and the downstream edge segment 112 is shorter than the upstream edge segment 111, when each umbrella piece 11 is folded, the area of ​​the umbrella surface 1 formed by the warp crease 14, the second downstream weft crease 162, the downstream rib 220, and the downstream edge segment 112 will pull the second support area 18 to automatically tilt and fold in the stacking direction, so that each folded umbrella piece 11 automatically stacks and rolls up towards the umbrella pole 3, which is neat and beautiful. There is no need to manually and inefficiently arrange the umbrella surface 1. If necessary, the user can directly tie it with the cable tie 7. The extension direction of the cable tie 7 from the root to the tip is the stacking direction. The cable tie 7 can be a Velcro strap or a snap fastener. To ensure that the umbrella surface 1 area enclosed by the warp crease 14, the second downstream weft crease 162, the downstream rib 220, and the downstream edge segment 112 automatically tilts and folds the second support area 18 in the stacking direction, the angle between the warp crease 14 and the angular midpoint 5 of the umbrella piece 11 is 0.1-10°, specifically 0.1, 0.5, 1, 1.5, 2, 2.5, 3, 3.5, 4, 4.5, 5, 5.5, 6, 7, 8, 9, or 10°. Preferably, the angle between the warp crease 14 and the angular midpoint 5 of the umbrella piece 11 is 1-5°. Specifically, the structure can be such that the first connecting part 12 is located on the inner segment 21, and the second connecting part 13 is located on the outer segment 22. Based on the fact that the first connecting part 12 is correspondingly close to the first bend 24 and the second connecting part 13 is correspondingly close to the second bend 25, this structure allows the umbrella surface 1 to adapt to the folding movements of the inner segment 21, the middle segment 23, and the outer segment 22, and to be driven to conform to the folding movements of the umbrella ribs 2.Furthermore, this design prevents excessive stress on the first connecting part 12 and the second connecting part 13, thus avoiding the stretching, pulling, and tearing of the first connecting part 12, the second connecting part 13, and the canopy 1 by the umbrella ribs 2, ensuring the umbrella's lifespan. To ensure smooth, efficient, and effortless folding of the canopy 1, the umbrella ribs 2 are equipped with an auxiliary spring 6 to assist in the folding and retraction of the umbrella ribs 2. When unlocking the folding buckle, the auxiliary spring 6 can use its own elasticity to enhance the folding and retraction action, force, and speed of the umbrella ribs 2. The specific structure can be as follows: the upper end of the umbrella rod 3 is provided with an upper umbrella nest 31 that is rotatably connected to each inner section rib 21, and a lower umbrella nest 32 that is movably sleeved on the umbrella rod 3 for driving the extension and retraction of the umbrella ribs 2; the lower umbrella nest 32 is located below the upper umbrella nest 31; the inner section rib 21 is provided with a support rib 26, with the direction towards the center of the umbrella surface 1 as the inner circle direction and the direction towards the outer circle of the umbrella surface 1 as the outer circle direction; the outer end of the support rib 26 is connected to both ends of the inner section rib 21 by a rotating shaft, the inner end of the support rib 26 is connected to the lower umbrella nest 32 by a rotating shaft, the inner end of the middle section rib 23 is connected to both ends of the support rib 26 by a first transmission rod 27, and the inner end of the outer section rib 22 is connected to the inner section rib 21 by a rotating shaft. The two ends of 21 are connected together by a second transmission rod 28; the first transmission rod 27, the inner segment bone 21, the middle segment bone 23 and the supporting bone 26 form a first parallelogram driving component, and the second transmission rod 28, the inner segment bone 21, the middle segment bone 23 and the outer segment bone 22 form a second parallelogram driving component; the inner segment bone 21 has a first rotating connection part 211 rotatably connected to the middle segment bone 23 and a second rotating connection part 212 rotatably connected to the supporting bone 26; one end of the auxiliary spring 6 is connected to the part between the first rotating connection part 211 and the second rotating connection part 212 of the inner segment bone 21, and the other end of the auxiliary spring 6 is connected to the supporting bone 26. The inner rib 21 and the middle rib 23 are rotated and folded through the first rotating connection 211, and the middle rib 23 and the outer rib 22 are rotated and folded through another rotating connection. When the lower umbrella nest 32 moves along the umbrella pole 3 relative to the upper umbrella nest 31, the support rod cooperates with the inner rib 21, the middle rib 23, the outer rib 22, the first transmission rod 27, and the second transmission rod 28 to drive the entire umbrella rib 2 to perform a stable extension or folding telescopic action using the first parallelogram drive component and the second parallelogram drive component. Specifically, the umbrella surface 1 and the inner rib 21, the middle rib 23, and the outer rib 22 can form a parallelogram in the middle area of ​​the umbrella surface 1, ensuring that the umbrella rib 2 is in a stable and durable state in the middle area of ​​the umbrella surface 1 during the telescopic action, without being stretched or wrinkled. The auxiliary spring 6 can specifically be a tension spring located within the first parallelogram-shaped drive member. The extension and deformation of the first parallelogram-shaped drive member can stretch the auxiliary spring 6 to store force. When the umbrella is closed, the auxiliary spring 6 releases the tension to enhance the folding and retraction action, force, and speed of the umbrella ribs 2. To ensure the torsional and flexural strength of the support plate 4, the support plate 4 is a resin sheet attached to or printed on the lower surface of the umbrella surface 1, with a thickness of 0.1-1 mm.The resin sheet also ensures that the support piece 4 and the entire umbrella are lightweight and easy to integrate with the umbrella surface 1. The second piece 42 has a large gap with the upstream umbrella rib 2, which reduces the weight of the umbrella surface 1 and also reduces the overall thickness of the umbrella surface 1 after folding and rolling, ensuring a lightweight and elegant umbrella after rolling. This invention may specifically include six or eight umbrella ribs 2, and the umbrella surface 1 may include six or eight umbrella pieces 11, depending on actual load-bearing and wind resistance requirements. The support piece 4 may specifically be one or a combination of two or more of the following: PVC resin sheet, PET resin sheet, PP resin sheet, PE resin sheet, ABS resin sheet, TPU resin sheet, PU resin sheet, and rubber resin sheet. To ensure that the support piece 4 has suitable torsional resistance, appropriate weight, and easy integration with the umbrella surface 1, the thickness of the support piece 4 is 0.1-0.1 mm, preferably 0.2-0.5 mm.

[0029] To ensure that each folded umbrella panel 11 automatically folds and rolls up towards the umbrella shaft 3, preferably, the second panel 42 has a second rib side edge 421 corresponding to the upstream rib 210 and a second warp side edge 422 corresponding to the warp crease 14. The second panel 42 gradually bends in the stacking direction from the second rib side edge 421 to the second warp side edge 422. When each umbrella panel 11 is folded, the second panel 42 bending in the stacking direction causes each folded umbrella panel 11 to automatically bend and tilt towards the umbrella shaft 3 and roll up.

[0030] To facilitate neat folding of the large umbrella canopy 1, preferably, a third support area 19 is formed between the first upstream weft crease 151, the upstream rib 210, the warp crease 14, and the umbrella shaft 3, where a support piece 4 is provided. The support piece 4 includes a third piece 44 located within the third support area 19. When the first bend 24 arches and bends towards the lower surface of the umbrella canopy 1, the outer end of the third piece 44 reinforces the inner end of the first piece 41, supporting the umbrella piece 11 to arch and bend towards the lower surface of the umbrella canopy 1 along the first upstream weft crease 151. Moreover, the third support area 19 is less prone to wrinkles and clutter under the support of the third piece 44, ensuring the neatness and orderliness of the third support area 19 when the umbrella canopy 1 is folded, and ensuring a neat and concentrated roll-up effect for the inner circle of the umbrella canopy 1 and the entire umbrella canopy 1 after folding. Specifically, the structure may include a second gap 45 between the third piece 44 and the first piece 41, with the first upstream weft crease 151 located within the second gap 45. The second gap 45 extends in the same direction as the first upstream weft crease 151. The second gap 45 provides a buffer space for folding the umbrella surface 1 at the first upstream weft crease 151, and also provides a buffer space for the relative folding of the first piece 41 and the third piece 44, ensuring smooth folding of the umbrella surface 1. To further ensure smooth folding space for the umbrella surface 1, the included angles of the third piece 44 and the warp crease 14 are chamfered, specifically smooth arc chamfers. Furthermore, the third piece 44 has a third bone side edge 441 corresponding to the upstream bone 210 and a third warp side edge 442 corresponding to the warp crease 14. The third piece 44 gradually bends in the stacking tilt direction from the third bone side edge 441 to the third warp side edge 442. When the inner ring of each umbrella piece 11 is folded, the third piece 44, which bends in the direction of stacking, causes each folded umbrella piece 11 to automatically bend and tilt towards the umbrella pole 3 in the third support area 19 of the inner ring and stack and roll up, ensuring that the inner ring of the umbrella surface 1 and the umbrella surface 1 as a whole are neat and compact after being rolled up.

[0031] To facilitate neat folding of the large umbrella canopy 1, preferably, the first downstream weft crease 152, the second downstream weft crease 162, the downstream rib 220, and the warp crease 14 form a fourth support area 10 for the support piece 4. The support piece 4 includes a fourth piece 46 disposed within the fourth support area 10. The fourth piece 46 cooperates with the first piece 41, and under the bending drive of the upstream rib 210 and the downstream rib 220, jointly drives the umbrella piece 11 to fold along the first weft crease 15 and the second weft crease 16. It can further support and resist twisting in the area of ​​the umbrella canopy 1 between the warp crease 14 and the downstream rib 220, avoiding wrinkles and ensuring the neatness and compactness of the inner circle of the umbrella canopy 1 and the entire umbrella canopy 1 after being rolled up. Specifically, the structure may include a third gap 47 between the fourth piece 46 and the first piece 41. The warp crease 14 extends along and passes through the third gap 47. The third gap 47 provides a buffer space for the folding of the umbrella surface 1 at the warp crease 14, and also provides a buffer space for the relative folding of the first piece 41 and the fourth piece 46, ensuring smooth folding of the umbrella surface 1. To further ensure smooth folding space for the umbrella surface 1, the included angles of the fourth piece 46 and the warp crease 14 are chamfered, specifically smooth arc chamfers. Furthermore, the fourth piece 46 has a fourth bone side edge 461 corresponding to the downstream bone 220 and a fourth warp side edge 462 corresponding to the warp crease 14. The fourth piece 46 gradually bends in the stacking tilt direction from the fourth bone side edge 461 to the fourth warp side edge 462. When the inner ring of each umbrella piece 11 is folded, the fourth piece 46, which bends in the direction of stacking, drives each folded umbrella piece 11 to automatically bend and tilt towards the umbrella pole 3 in the third support area 19 in the middle of the three sides, and stack and roll up, ensuring that the inner ring of the umbrella surface 1 and the umbrella surface 1 as a whole are neat and compact after being rolled up.
