When storing the umbrella, the inner ribs 21, middle ribs 23, and outer ribs 22 of each umbrella rib 2 are folded and bent. With the assistance of the support piece, each umbrella panel 11 of the umbrella surface is folded along the meridian folds 14, the first latitude fold, and the second latitude fold of the umbrella panel. After each umbrella panel is folded and stored, the umbrella surface area surrounded by the meridian folds, the second downstream latitude fold 162, the downstream rib 220, and the downstream edge 112 is pulled by the second support area 18, which automatically tilts toward the stacking inclination direction for storage.

Description

Technical Field

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

Background Art

[0002] Umbrellas are supplies frequently used in daily life. Currently, when commercially available umbrellas are folded after use, the umbrella surface becomes messy and uneven, lacking order and regularity. It is necessary to manually arrange and fold them, which is not aesthetically pleasing, time-consuming, and inconvenient.

[0003] For example, Chinese invention patent CN202011433546.8 discloses an umbrella holder that is easy to store and organize, comprising an umbrella surface, umbrella frame, umbrella ribs, umbrella handle, a convex folding guide sheet, and a concave folding guide sheet, the convex and concave folding guide sheets being provided on the umbrella surface. The umbrella holder is distributed outward from the center point, the umbrella frame supports the umbrella surface, and each umbrella surface is formed by the branching of the umbrella frame, and by providing folding guide sheets on different umbrella surfaces, the umbrella can be folded neatly. The umbrella holder is a tri-fold umbrella, and the tri-fold is divided into an inner layer, a middle layer, and an outer layer. The folding guide sheets have two types of structures: one is a convex folding guide sheet and the other is a concave folding guide sheet, which together form the folding crease, the folding guide sheets are viscous and can be fixed to the umbrella surface, and are flexible and curved. The concave folding guide sheet has a single recessed fold in the center, with the recessed fold facing upwards, and when the sheet is subjected to force, it closes upwards. The convex folding guide sheet has a single protruding convex strip in the center, with the convex strip facing upwards, and when the sheet is subjected to force, it closes downwards. The convex and concave folding guide sheets are made of PVC, PET, PP, PE, ABS, TPU, PU, ​​silicone, rubber, or EVA. The umbrella mechanism is a manual umbrella, automatic umbrella, or electric umbrella. The umbrella frame or ribs for folding the umbrella mechanism are a three-fold umbrella, a four-fold umbrella, or a five-fold umbrella. The umbrella mechanism further includes a band on the outside of the umbrella surface to securely fasten the umbrella surface.

[0004] This invention aims to solve the problem of difficulty in rolling up and storing umbrellas, but its effect is not ideal. The folds in the sheet prevent the entire umbrella surface from being rolled up neatly, resulting in a messy, wrinkled, and other disordered state when the umbrella surface is rolled up. Furthermore, the folded umbrella surface scatters and does not automatically gather together in the direction of rolling up, requiring the user to go through a lot of trouble, and there is room for improvement in terms of convenience and practicality.

[0024] After adopting the above technical solutions, the easy-to-store umbrella of this invention breaks away from the structural form of conventional umbrellas. In actual use, the support pieces have higher folding strength than the umbrella surface. When folding the umbrella, the inner, middle, and outer ribs of each umbrella frame are folded and bent, and with the assistance of the support pieces, each umbrella panel of the umbrella surface is folded along the meridian folds, the first latitude folds, and the second latitude folds of the umbrella panel. Specifically, the first and second pieces support the first and second support areas, making them flat and fold-resistant. In order to achieve this, the folding and bending of the upstream ribs causes the umbrella surface area between the meridian fold and the upstream rib to fold along the first upstream latitude fold and the second upstream latitude fold. For example, the first bend is bent in an arch shape toward the lower surface of the umbrella surface, and the second bend is bent in an arch shape toward the upper surface of the umbrella surface. The first and second bends utilize the first and second connections to cause the umbrella surface area between the meridian fold and the upstream rib to fold accordingly. Based on the flexural strength of the first and second halves, the first and second halves utilize their flexural performance to enhance the folding motion of the umbrella surface area between the meridian folds and the upstream ribs along the first and second upstream latitude folds. Simultaneously, the umbrella surface area between the meridian folds and the downstream ribs folds along the first and second downstream latitude folds in accordance with the combined action of the folding motion of the downstream ribs and the folding motion of the umbrella surface area between the meridian folds and the upstream ribs. Furthermore, with the support of the first and second halves, the umbrella surface area between the meridian folds and the upstream ribs and the umbrella surface area between the meridian folds and the downstream ribs fold along the meridian folds. Each umbrella panel folds and stores efficiently, smoothly, and neatly, arranging around the umbrella pole. Furthermore, because the meridian fold is located between the angle midpoint of the umbrella panel and the downstream rib, the downstream edge is shorter than the upstream edge. After each umbrella panel is folded and stored, the umbrella surface area enclosed by the meridian fold, the second downstream latitude fold, the downstream rib, and the downstream edge is pulled to automatically tilt the second support area in the direction of the stacking inclination. As a result, each folded and stored umbrella panel automatically stacks and rolls towards the umbrella pole, resulting in a neat and beautiful finish. There is no need to manually organize the umbrella surface in an inefficient and cumbersome manner, and it can be secured directly with cable ties as needed.Compared with the prior art, the umbrella of the present invention that is easy to store has advantages such as efficient and orderly winding storage, and excellent convenience and practicality.

The umbrella surface 1 is provided with a support piece 4 that is provided along the umbrella surface 1 and has a bending strength higher than that of the umbrella surface 1. The umbrella ribs 2 include an inner rib 21 that supports the inner circumference of the umbrella surface 1 and is connected to the umbrella pole 3, an outer rib 22 that supports the outer circumference of the umbrella surface 1, and a middle rib 23 that supports the middle part of the umbrella surface 1 and is connected between the inner rib 21 and the outer rib 22. There is a first bending portion 24 between the inner rib 21 and the middle rib 23, and a second bending portion between the middle rib 23 and the outer rib 22. The umbrella surface 1 has a bent portion 25, and the umbrella surface 1 includes a plurality of umbrella panels 11 located between adjacent umbrella ribs 2, each umbrella panel 11 having a connecting portion connected to the umbrella ribs 2, the connecting portion having a first connecting portion 12 corresponding to a first bent portion 24 and a second connecting portion 13 corresponding to a second bent portion 25, the umbrella panel 11 having a meridian fold 14 located between adjacent umbrella ribs 2 and extending along the radial direction of the umbrella surface 1, a first parallel fold 15 located between adjacent umbrella ribs 2 and corresponding to the first connecting portion 12, and a second parallel fold 16 located between adjacent umbrella ribs 2 and corresponding to the second connecting portion 13, the umbrella surface 1 is folded After folding, the umbrella pole 3 is stored tilted in the same clockwise direction and has a stacking tilt direction in which the ribs are stacked and wound together with the umbrella pole 3, and two adjacent umbrella ribs 2 along the stacking tilt direction are defined as the upstream rib 210 and the downstream rib 220, respectively, with the downstream rib 220 being on the stacking tilt direction side of the upstream rib 210, and the first latitude fold 15 includes the first upstream latitude fold 151 connected between the meridian fold 14 and the first bend 24 of the upstream rib 210, and the first downstream latitude fold 152 connected between the meridian fold 14 and the first bend 24 of the downstream rib 220, and the second latitude fold 16 is a meridian fold The first upstream latitude fold 151 is connected between the fold 14 and the second bend 25 of the upstream rib 210, and the second downstream latitude fold 162 is connected between the meridian fold 14 and the second bend 25 of the downstream rib 220, the first upstream latitude fold 151 is gradually inclined toward the outer edge of the umbrella panel 11 from the upstream rib 210 to the meridian fold 14, the first downstream latitude fold 152 is gradually inclined toward the outer edge of the umbrella panel 11 from the downstream rib 220 to the meridian fold 14, the first upstream latitude fold 151 and the first downstream latitude fold 152 intersect the meridian fold 14,The second upstream latitude fold 161 gradually slopes toward the outer edge of the umbrella panel 11 from the upstream rib 210 to the meridian fold 14, and the second downstream latitude fold 162 gradually slopes toward the outer edge of the umbrella panel 11 from the downstream rib 220 to the meridian fold 14, and the second upstream latitude fold 161 and the second downstream latitude fold 162 intersect at the meridian fold 14, that is, the first upstream latitude fold 151 and the first downstream latitude fold 152 intersect at the meridian fold 14 and form a pointed angle toward the outer edge of the umbrella surface 1, and the second The upstream latitude fold 161 and the second downstream latitude fold 162 intersect at the meridian fold 14, forming a pointed angle toward the outer circumference of the umbrella surface 1. This structure allows the umbrella panel 11 to adapt and fold in accordance with the folding motion of the umbrella ribs 2. When the first upstream latitude fold 151 and the second upstream latitude fold 161 are parallel, and the first downstream latitude fold 152 and the second downstream latitude fold 162 are parallel, the effect of the umbrella panel 11 adapting and folding in accordance with the folding motion of the umbrella ribs 2 is enhanced. A first support area 17 for installing the support piece 4 is formed by the first upstream latitude fold 151, the second upstream latitude fold 161, the upstream rib 210 and the meridian fold 14, and a second support area 18 for installing the support piece 4 is formed by the second upstream latitude fold 161, the upstream rib 210, the meridian fold 14 and the outer edge of the umbrella panel 11, and the support piece 4 includes a first piece 41 provided in the first support area 17 and a second piece 42 provided in the second support area 18, with a first gap 43 between the first piece 41 and the second piece 42, the second upstream latitude fold 161 being in the first gap 43 and the first gap 43 being in the second upstream latitude fold 161 Similar to the extension direction, the first gap 43 not only provides buffer space for folding the umbrella surface 1 at the second upstream latitude fold 161, but also provides buffer space for the relative folding of the first piece 41 and the second piece 42, ensuring the smooth folding of the umbrella surface 1. To further ensure that the umbrella surface 1 has a smooth folding space, the angle corresponding to the support piece 4 and the meridian fold 14 has a chamfer, which can be a smooth arc-shaped chamfer. The meridian fold 14 is located between the angle midpoint 5 of the umbrella panel 11 and the downstream umbrella rib 2, and the outer edge of the umbrella panel 11 is the upstream edge portion 111 located between the meridian fold 14 and the upstream rib 210.The and includes a downstream edge 112 between the meridian fold 14 and the downstream bone 220, the downstream edge 112 being shorter than the upstream edge 111, the first downstream latitude fold 152 being shorter than the first upstream latitude fold 151, and the second downstream latitude fold 162 being shorter than the second upstream latitude fold 161. In this invention, during actual use, the support piece 4 has higher bending strength than the umbrella surface 1, and when storing the umbrella, the inner ribs 21, middle ribs 23 and outer ribs 22 of each umbrella frame 2 are folded and bent, and with the assistance of the support piece 4, each umbrella panel 11 of the umbrella surface 1 is folded along the meridian fold 14, the first latitude fold 15 and the second latitude fold 16 of the umbrella panel 11, specifically the first piece 41 and the second piece 42 support the first support area 17 and the second support area 18, making them flat and fold-resistant, and as the upstream ribs 210 are folded, the area of ​​the umbrella surface 1 between the meridian fold 14 and the upstream ribs 210 is folded along the first upstream latitude fold 151 and the second upstream latitude fold 161, for example towards the center of the umbrella surface 1 The direction of the first bend is defined as the inward circumferential direction, and the direction toward the outer circumference of the umbrella surface 1 is defined as the outward circumferential direction. The first bend portion 24 is bent in an arch shape toward the lower surface of the umbrella surface 1, and the inner end of the first piece 41 supports the umbrella panel 11 so that it is bent in an arch shape toward the lower surface of the umbrella surface 1 along the first upstream latitude fold 151, and the second bend portion 25 so that it is bent in an arch shape toward the upper surface of the umbrella surface 1, and the outer end of the first piece 41 supports the umbrella panel 11 so that it is bent in an arch shape toward the upper surface of the umbrella surface 1 along the second upstream latitude fold 161. The first bend portion 24 and the second bend portion 25 utilize the first connection portion 12 and the second connection portion 13 to cause the umbrella surface 1 region between the meridian fold 14 and the upstream rib 210 to fold accordingly. Based on the flexural strength of the first and second halves 41 and 42, the first and second halves 41 and 42 utilize their flexural properties to enhance the folding of the umbrella surface area 1 between the meridian fold 14 and the upstream rib 210 along the first upstream latitude fold 151 and the second upstream latitude fold 161, and simultaneously, the umbrella surface area 1 between the meridian fold 14 and the downstream rib 220 folds along the first downstream latitude fold 152 and the second downstream latitude fold 162 in accordance with the combined action of the folding and bending motion of the downstream rib 220 and the folding motion of the umbrella surface area 1 between the meridian fold 14 and the upstream rib 210, andSupported by the first and second halves 41 and 42, the umbrella surface area 1 between the meridian fold 14 and the upstream rib 210 and the umbrella surface area 1 between the meridian fold 14 and the downstream rib 220 are folded along the meridian fold 14. Each umbrella panel 11 is efficiently, smoothly, and neatly folded and stored, allowing them to be arranged around the umbrella pole 3. Furthermore, the meridian fold 14 is located between the angle midpoint 5 of the umbrella panel 11 and the downstream umbrella rib 2, and the downstream edge 112 is shorter than the upstream edge 111. After each umbrella panel 11 is folded and stored, the umbrella surface 1 area enclosed by the meridian fold 14, the second downstream latitude fold 162, the downstream rib 220, and the downstream edge 112 is pulled to automatically tilt the second support area 18 in the stacking inclination direction for storage. After folding and storing, each umbrella panel 11 automatically stacks and rolls up towards the umbrella pole 3, resulting in a neat and beautiful arrangement. There is no need to manually organize the umbrella surface 1 in an inefficient and cumbersome manner. If necessary, it can be simply tied directly with a cable tie 7. The extension direction of the cable tie 7 from the base to the tip is the stacking inclination direction, and the cable tie 7 is specifically a Velcro® type band or a snap button type band. The area of ​​the umbrella surface 1 enclosed by the meridian fold 14, the second downstream latitude fold 162, the downstream rib 220, and the downstream edge 112 has a tension effect that ensures the second support area 18 is automatically tilted and stored toward the lamination inclination direction. The angle between the meridian fold 14 and the angular midpoint 5 of the umbrella panel 11 in which it is located 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 1-5°. The specific structure is such that the first connecting part 12 is provided on the inner rib 21, and the second connecting part 13 is provided on the outer rib 22. This structure allows the umbrella surface 1 to move in accordance with the folding movements of the inner rib 21, middle rib 23, and outer rib 22, and adapt to the folding movements of the umbrella ribs 2, while preventing excessive force from acting on the first connecting part 12 and the second connecting part 13.The second connection part 13 and the umbrella surface 1 are prevented from being subjected to tension or tearing due to the expansion and contraction of the umbrella ribs 2, thereby ensuring the lifespan of the umbrella. To ensure smooth, efficient, and labor-saving storage of the umbrella surface 1, an auxiliary spring 6 is placed on the umbrella ribs 2 to assist in the contraction and folding of the umbrella ribs 2. When releasing the umbrella closing buckle, the auxiliary spring 6 can enhance the folding and contraction operation, force, and speed of the umbrella ribs 2 by its own elasticity. The specific structure may be as follows. An upper hub 31 is provided at the upper end of the umbrella pole 3, which is rotatably connected to each inner rib 21, and a lower hub 32 is provided which is movably fitted to the umbrella pole 3 to drive the extension and retraction of the umbrella ribs 2. The lower hub 32 is located below the upper hub 31, and support ribs 26 are arranged on the inner ribs 21. The direction toward the center of the umbrella surface 1 is the inward circumferential direction, and the direction toward the outer circumference of the umbrella surface 1 is the outward circumferential direction. The outer end of the support rib 26 is connected to both ends of the inner rib 21 via a rotating shaft, the inner end of the support rib 26 is connected to the lower hub 32 via a rotating shaft, and the inner end of the middle rib 23 is connected to both ends of the support rib 26 via a first transmission rod 27, and the inner end of the outer rib 22 and the inner rib 2 A second transmission rod 28 is connected to both ends of 1, and the first transmission rod 27, inner frame 21, middle frame 23, and support frame 26 constitute a first parallelogram drive member, and the second transmission rod 28, inner frame 21, middle frame 23, and outer frame 22 constitute a second parallelogram drive member, the inner frame 21 has a first rotatable connection part 211 that is rotatably connected to the middle frame 23, and a second rotatable connection part 212 that is rotatably connected to the support frame 26, one end of the auxiliary spring 6 is connected to the portion of the inner frame 21 between the first rotatable connection part 211 and the second rotatable connection part 212, and the other end of the auxiliary spring 6 is connected to the support frame 26. The inner ribs 21 and middle ribs 23 are rotated and folded by the first rotating connection part 211, and the middle ribs 23 and outer ribs 22 are rotated and folded by the other rotating connection part. As the lower hub 32 moves along the umbrella pole 3 relative to the upper hub 31, the support rod, together with the inner ribs 21, middle ribs 23, outer ribs 22, first transmission rod 27, and second transmission rod 28, utilizes the first and second parallelogram drive members to perform a stable unfolding or folding extension and retraction movement of the entire umbrella frame 2. Specifically, the umbrella surface 1 and the inner ribs 21, middle ribs 23, and outer ribs 22 form a parallelogram in the central region of the umbrella surface 1, and the central region of the umbrella surface 1 is also stretched during the extension and retraction process of the umbrella frame 2.A stable and sustained state is maintained without the formation of wrinkles. The auxiliary spring 6 may specifically be a tension spring located within the first parallelogram drive member, and the extension deformation motion of the first parallelogram drive member can be used to pull the auxiliary spring 6 and store energy. When closing the umbrella, the auxiliary spring 6 releases the tension force, strengthening the folding and contracting motion, force, and speed of the umbrella ribs 2. In order to ensure the bending and deflection strength of the support piece 4, The support piece 4 is a resin piece bonded or printed to the lower surface of the umbrella surface 1, and the thickness of the support piece 4 is 0.1-1 mm. The resin piece ensures weight reduction of the support piece 4 and the entire umbrella, and facilitates connection with the umbrella surface 1. There is a large gap between the second piece 42 and the upstream umbrella rib 2, which reduces the weight of the umbrella surface 1 and simultaneously reduces the overall thickness of the umbrella surface 1 after folding and rolling it up, ensuring that the umbrella is lightweight and compact after rolling it up. Depending on the requirements of actual load-bearing capacity and wind resistance, this invention can specifically include 6 or 8 umbrella ribs 2, and the umbrella surface 1 can include 6 or 8 umbrella panels 11. The support piece 4 is specifically one or more combinations of PVC resin piece, PET resin piece, PP resin piece, PE resin piece, ABS resin piece, TPU resin piece, PU resin piece, and rubber resin piece. To provide the support piece 4 with appropriate bending characteristics and weight, and to facilitate alignment with the umbrella surface 1, the thickness of the support piece 4 is set to 0.1-0.1 mm, preferably 0.2-0.5 mm.

[0028] To ensure that the folded umbrella panels 11 automatically stack and roll up onto the umbrella pole 3 after being stored, preferably the second piece 42 has a second rib side edge 421 corresponding to the upstream rib 210 and a second meridian side edge 422 corresponding to the meridian fold 14, and the second piece 42 gradually curves in the stacking inclination direction from the second rib side edge 421 to the second meridian side edge 422. After each umbrella panel 11 is folded and stored, each second piece 42 that curves in the stacking inclination direction automatically curves and inclins toward the umbrella pole 3, stacking and rolling up the stored umbrella panels 11.

[0029] To facilitate the neat folding and storage of the large umbrella surface 1, preferably, a third support area 19 is formed surrounding the first upstream latitude fold 151, the upstream ribs 210, the meridian fold 14, and the umbrella shaft 3, and the support piece 4 includes a third piece 44 provided within the third support area 19. When the first bending portion 24 is folded in an arch shape toward the lower surface of the umbrella surface 1, the outer end of the third piece 44 reinforces and supports the inner end of the first piece 41, supporting the umbrella panel 11 so that it is folded in an arch shape toward the lower surface of the umbrella surface 1 along the first upstream parallel fold 151. Furthermore, the support of the third piece 44 makes it less likely for wrinkles and disorder to occur in the third support area 19, ensuring that the third support area 19 is neat and orderly when the umbrella surface 1 is folded, and ensuring an orderly and concentrated rolling storage effect after folding the inner circumference of the umbrella surface 1 and the entire umbrella surface 1.

There is a second gap 45 between the third piece 44 and the first piece 41, the first upstream latitude fold 151 is located in the second gap 45, the second gap 45 is in the same direction as the extension of the first upstream latitude fold 151, the second gap 45 can retain a buffer space for folding the umbrella surface 1 at the first upstream latitude fold 151, and can also retain a buffer space for the relative folding of the first piece 41 and the third piece 44, and in order to ensure the smooth folding of the umbrella surface 1 and to ensure that the umbrella surface 1 has a smooth folding space, the angles corresponding to the third piece 44 and the meridian fold 14 are both chamfered, specifically, they may be smooth arc-shaped chamfers. Furthermore, the third piece 44 has a third rib side edge 441 corresponding to the upstream rib 210 and a third meridian side edge 442 corresponding to the meridian fold 14, and the third piece 44 gradually curves in the stacking inclination direction from the third rib side edge 441 to the third meridian side edge 442. After the inner circumference of each umbrella panel 11 is folded and stored, each third piece 44 that curves in the stacking inclination direction automatically curves and inclins the third support area 19 on the inner circumference of each stored umbrella panel 11 toward the umbrella pole 3, stacking and rolling up together, ensuring that the inner circumference of the umbrella surface 1 and the entire umbrella surface 1 are neat and compact after storage.

[0030] To facilitate the neat folding and storage of the large umbrella surface 1, preferably, a fourth support area 10 for installing the support piece 4 is formed by surrounding a first downstream latitude fold 152, a second downstream latitude fold 162, a downstream rib 220, and a meridian fold 14, and the support piece 4 includes a fourth piece 46 provided within the fourth support area 10. Together with the first piece 41, the fourth piece 46, driven by the bending of the upstream rib 210 and the downstream rib 220, causes the jointly positioned umbrella panel 11 to fold along the first latitude fold 15 and the second latitude fold 16, further supporting the umbrella surface 1 area between the meridian fold 14 and the downstream rib 220, resisting bending, avoiding wrinkles, and ensuring the inner circumference of the umbrella surface 1 and the entire umbrella surface 1 are neatly and compactly stored. The specific structure has a third gap 47 between the fourth piece 46 and the first piece 41, the meridian fold 14 extends along the third gap 47 and penetrates the third gap 47, the third gap 47 can retain a buffer space for folding the umbrella surface 1 at the meridian fold 14 and can also retain a buffer space for relative folding of the first piece 41 and the fourth piece 46, and in order to ensure the smooth folding of the umbrella surface 1 and to ensure that the umbrella surface 1 has a smooth folding space, the angles corresponding to the fourth piece 46 and the meridian fold 14 are both chamfered, and may specifically be smooth arc-shaped chamfers. Furthermore, the fourth piece 46 has a fourth rib side edge 461 corresponding to the downstream rib 220 and a fourth meridian side edge 462 corresponding to the meridian fold 14, and the fourth piece 46 gradually curves in the stacking inclination direction from the fourth rib side edge 461 to the fourth meridian side edge 462. After the inner circumference of each umbrella panel 11 is folded and stored, each fourth piece 46 that curves in the stacking inclination direction automatically curves and inclins the third support area 19 located in the middle of the three sides of each stored umbrella panel 11 toward the umbrella pole 3, causing them to stack together and roll up for storage, ensuring that the inner circumference of the umbrella surface 1 and the entire umbrella surface 1 are neatly and compactly stored.
