Description

Technical Field

[0001] The invention relates to the technical field of umbrella devices, and in particular to a straight-bone umbrella with a hidden umbrella surface. Background Art

[0002] Umbrellas are daily necessities that people often carry with them when traveling. They are usually used when it rains or when the sun shines. Umbrellas can effectively block rain and sunlight outside the umbrella, bringing a lot of convenience to daily life. There are many types of existing umbrellas, such as straight rib umbrellas, folding umbrellas, reverse umbrellas, beach umbrellas, etc. The above existing umbrellas are composed of three major parts: a rib umbrella surface for shielding, a supporting middle rod, and a hand grip.

[0003] However, no matter it is an existing straight umbrella, folding umbrella or beach umbrella, part of the umbrella surface is exposed to the outside after the umbrella is folded after use on rainy days, so that the residual rain water on the umbrella surface may still wet the contact objects. Although the reverse umbrella can store the umbrella surface inside after the umbrella is folded, the umbrella surface and the bead tail will spread out around after the umbrella is folded, which is not tight enough, and the umbrella strap needs to be tightened again. Even if the umbrella strap is tightened, the bead tail can still be seen, thus affecting the convenience of use, and the exposure of the umbrella surface and the bead tail will also affect the appearance.

[0004] Therefore, the applicant conducts in-depth research on the above-mentioned problems to meet people's needs. Summary of the invention

[0005] The purpose of the present invention is to provide a straight-bone umbrella in which the umbrella cover and the ribs can be hidden inside a middle rod or an outer tube to address the deficiencies in the prior art, so as to effectively prevent the bead tail or the umbrella tail from accidentally bruising others, and to achieve neatness, beauty, environmental protection and convenience in carrying.

[0006] The present invention achieves the above-mentioned purpose through the following technical solutions: a straight-bone umbrella with a hidden umbrella cover, comprising: an outer tube, an opening and closing sleeve, a connecting rod, an upper nest, a lower nest, an umbrella rib and a pull wire. Among them: the opening and closing sleeve is movably sleeved on the outer wall of the outer tube; the connecting rod is inserted in the outer tube; the upper nest is installed on the top of the connecting rod; the lower nest is movably sleeved on the connecting rod; the umbrella rib is respectively connected to the upper nest and the lower nest; the pull wire is respectively connected to the opening and closing sleeve and the connecting rod, and is used to lift and lower the connecting rod along the axial direction of the outer tube by pushing the opening and closing sleeve;

[0007] When the umbrella is folded, the ribs can be stored inside the outer tube.

[0008] A relatively large and hollow outer tube is used to contain or wrap the umbrella and ribs after the umbrella is folded. This provides the necessary space and structural support for "hiding the umbrella", solving the problem that most of the umbrella is still exposed after the traditional umbrella is folded.

[0009] The opening and closing sleeve, which is arranged on the outer wall of the outer tube and can move up and down along the outer tube, is an external operating component for the umbrella to realize the "opening and closing" or "lifting and lowering" action. The user can control the expansion and contraction of the umbrella by pushing or pulling the opening and closing sleeve without directly touching the internal ribs or umbrella surface.

[0010] The connecting rod inserted into the outer tube cooperates with the main opening and closing parts such as the upper nest and the lower nest. The axial movement of the connecting rod in the outer tube can drive the ribs and the umbrella surface to extend or close. Its "straight rib" structure is simpler and stronger than that of traditional folding umbrellas, which helps the umbrella cloth to be smoothly brought into the outer tube after the umbrella is folded, further reducing the degree of exposure.

[0011] The upper nest is fixed at the top of the connecting rod, and the lower nest is movably connected to the connecting rod. After the two are connected to each other through the ribs, they will move relative to each other during the process of opening or closing the umbrella, thereby driving the umbrella to expand or close. When closing the umbrella, the lower nest moves towards the upper nest, so that the ribs and the umbrella can be folded into the inner part of the outer tube.

[0012] The ribs are connected to the upper nest and the lower nest respectively, supporting the umbrella cloth to form the umbrella surface. Due to the "straight rib" feature of this solution, the lifting direction of the ribs after folding is parallel to the outer tube, making it easier to put the ribs and the umbrella cloth into the outer tube as a whole, reducing or avoiding the exposure of the cloth surface and the bead tail, and solving the problem of residual raindrops after the traditional umbrella is folded.

[0013] The pull wires are connected between the opening and closing sleeves and the connecting rods, and are wound through the pulleys at the top or bottom of the outer tube, thus realizing the function of remotely pulling or pushing the connecting rods. Therefore, the user only needs to operate the opening and closing sleeves outside the outer tube, without manually folding the umbrella surface, and can reliably pull the umbrella surface and the ribs into the outer tube when closing the umbrella, thus realizing the purpose of "hiding the umbrella surface".

[0014] As a further solution of the present invention: the umbrella rib includes a long bone hinged to the upper nest, and a short bone with two ends hinged to the long bone and the lower nest respectively;

[0015] The long ribs are sewn with umbrella cloth; when the umbrella is folded, the umbrella cloth and the ribs can be completely retracted into the outer tube;

[0016] The top and bottom of the outer tube are respectively provided with pulleys around which the pull wires pass;

[0017] A linkage plug connected to the pull wire is provided at the bottom of the connecting rod. Specifically, through the articulation of the long and short bones, a smoother umbrella surface can be opened when the umbrella is opened, enhancing the windproof and shielding effects. The top and bottom pulley distribution makes the movement of the pull wire smoother, avoids direct friction between the pull wire and the outer tube, and prolongs the service life. A linkage plug is provided at the bottom of the connecting rod, which is firmly and reliably connected to the pull wire, realizing concentrated force when closing the umbrella, allowing the umbrella ribs to be smoothly retracted.

[0018] As a further solution of the present invention: the pull line includes an opening line and a closing line, one end of the opening line is connected to the linkage plug, the other end of the opening line bypasses the pulley at the top of the outer tube and is connected to the opening and closing sleeve, one end of the closing line is connected to the linkage plug, the other end of the closing line bypasses the pulley at the bottom of the outer tube and is connected to the opening and closing sleeve. Specifically, the opening line and the closing line are responsible for the opening and closing actions respectively, avoiding the risk of uneven tightness or knotting caused by the two-way operation of a pull line. The user can pull the opening line or the closing line separately as needed to partially or completely open and close the umbrella. If a pull line is worn or needs to be replaced, it will not affect the normal function of the other line, thereby improving the service life and maintenance convenience.

[0019] As a further solution of the present invention: a top sleeve is provided at the top of the outer tube, and the pulley at the top of the outer tube is installed on the top sleeve;

[0020] An umbrella handle is arranged at the bottom of the outer tube, and a pulley at the bottom of the outer tube is installed on the umbrella handle;

[0021] The long bone is provided with a first joint located at one end of the long bone, a bead tail located at the other end of the long bone, and a middle dish located between the joint and the bead tail, and the first joint is connected to the upper nest;

[0022] One end of the short bone is provided with a second joint connected to the middle dish and a third joint connected to the lower nest;

[0023] The top of the connecting rod is also provided with an umbrella tail for fixing the umbrella cloth to the upper nest. Specifically, the top cover and the umbrella handle carry pulleys respectively, making the overall appearance more compact and the skeleton easier to disassemble or maintain. The setting of detailed parts such as the middle dish and the bead tail allows the ribs to move smoothly, avoiding deformation of the umbrella surface or uneven force. The umbrella handle at the bottom matches the top cover, visually echoing the top and bottom; at the same time, it is convenient for users to hold the operation.

[0024] As a further solution of the present invention: the straight-bone umbrella with hidden umbrella surface also includes:

[0025] A positioning member is movably mounted on the connecting rod and is located at the bottom of the lower nest;

[0026] An elastic buckle head, one end of which is hinged inside the connecting rod, and the other end of which partially extends outside the connecting rod and is located at the bottom of the lower nest; and

[0027] A windbreak line, one end of which is connected to the end of the long bone away from the short bone, and the other end is connected to the positioning piece;

[0028] Among them, a limiting portion is provided at the top of the connecting rod, which is supported by the positioning piece to limit the positioning piece. Specifically, the elastic buckle head is provided with a clamping protrusion, which can extend out of the connecting rod or be pushed back into the connecting rod by the inclined surface at the bottom of the positioning piece. Specifically, the windproof line can pre-bend the long ribs when the umbrella cloth is not fully unfolded, reducing the risk of the umbrella surface folding or buckling toward the sky during reverse opening and closing. The positioning piece cooperates with the elastic buckle head to form limitations or releases at different stages during the umbrella opening process, so that the umbrella ribs can be unfolded according to a predetermined path or sequence. The clamping protrusion and the inclined surface realize automatic or semi-automatic holding, avoiding the user's manual intervention in too many details and improving the user experience.

[0029] As a further solution of the present invention: the lower nest comprises a lower nest part and a sleeve part respectively sleeved on the connecting rod;

[0030] The positioning piece is movably sleeved on the sleeve portion and is located at the bottom of the lower nest portion;

[0031] The elastic buckle is located at the bottom of the sleeve part, and the other end of the elastic buckle partially extends out of the connecting rod to support the sleeve part. Specifically, the umbrella opening / closing stage can be carried out in steps, and different parts are subjected to independent forces, reducing the impact or wear on the entire umbrella rib system. The sleeve part is relatively independent of the positioning piece, and the opening and closing path, angle or time can be fine-tuned to achieve smoother opening and closing of the umbrella surface. The lower nest part and the sleeve part form a more stable support mode through the elastic buckle and the windproof line, which is further conducive to pre-bending the long bones during the umbrella opening action.

[0032] As a further solution of the present invention, the bottom of the positioning member is provided with an inclined surface which is supported by the elastic buckle head, so as to completely push the part of the elastic buckle head extending outside the connecting rod into the connecting rod. Specifically, through the action of the inclined surface, the elastic buckle head can be naturally transitioned from "locked" to "unlocked" without additional manual pressing, so that the action transition of pre-bending the long bone during the umbrella opening action is more natural.

[0033] As a further solution of the present invention: the straight-bone umbrella with concealed umbrella cover also includes a top cover, and a limiting part is arranged on the top cover, specifically, the flange at the bottom of the top cover is used as a limiting part to resist and limit the positioning piece, and a reset spring is arranged in the connecting rod to push the elastic buckle part out of the connecting rod. Specifically, the user does not need manual intervention, and the overall device can automatically return the elastic buckle to its position, thereby improving the degree of automation. Through the top cover limiting part + reset spring, the upward and downward positions of the positioning piece can be bidirectionally constrained, and the structure is more reliable. Integrating the limiting design into the top cover does not destroy the aesthetic appearance, and fully utilizes the space to complete key functions.

[0034] As a further solution of the present invention, the pulley at the top of the outer tube is installed on the top cover. Specifically, the pulley is installed inside the top cover, making the top of the outer tube more compact, which is beneficial to reduce the contact or entanglement between the umbrella cover and the pulley when opening and closing. The top cover itself can provide better support, and the pulley is installed more firmly and is not easy to shift or loosen. After the layout is simplified, the movement path of the pull wire when opening and closing the umbrella is shorter and smoother, reducing wire wear.

[0035] As a further solution of the present invention: the top cover is in an inverted trumpet structure, and the limiting part is arranged at the bottom of the top cover; specifically, the inner diameter of the top cover gradually increases from bottom to top (or the shape is similar to a trumpet), so as to reduce the friction between the umbrella cloth and the cover wall when the umbrella is folded; a protrusion or annular step can be arranged at the bottom to limit the positioning piece.

[0036] The positioning member is a tubular structure and is arranged in the outer tube. The sleeve part and the connecting rod are both inserted in the positioning member. A limiting protrusion for locking in the limiting part is provided at the bottom of the positioning member. Specifically, when the positioning member is pulled up, the limiting protrusion at the bottom of the positioning member is locked in the limiting part of the top sleeve, thereby limiting the maximum lifting distance of the positioning member. Specifically, the inner diameter of the positioning member can accommodate the sleeve part and the connecting rod at the same time, and each component remains coaxial or approximately coaxial in the positioning member, and the movement is smoother; the limiting protrusion protruding from the bottom of the positioning member is engaged with the limiting part at the bottom of the top sleeve to prevent the positioning member from rising infinitely. Through the contact position of the limiting protrusion and the limiting part, the upper and lower limit positions can be preset, so that the umbrella ribs can be unfolded just right without excessive force.

[0037] Beneficial effects of the present invention:

[0038] This solution allows the umbrella and ribs to move inside the outer tube and be partially or completely covered when the umbrella is folded, effectively solving the problem of "exposed umbrella causing dripping, wetting or affecting the appearance". After using the umbrella on a rainy day, the user can operate the opening and closing sleeve to drive the connecting rod and ribs to retract into the outer tube, which can greatly reduce the area of ​​the umbrella and the bead tail exposed to the outside, thereby reducing the wetting of the surrounding environment by rainwater, which helps to improve the convenience of use and appearance.

[0039] 1. The umbrella surface and ribs are effectively hidden to reduce the impact of residual moisture on the environment

[0040] Compared with traditional umbrellas where a large area of ​​the umbrella cover is still exposed after being folded, the present invention utilizes the cooperation of the outer tube with the connecting rod, the upper nest, the lower nest and the pull wire to allow most (or even all) of the umbrella cover to enter the inner part of the outer tube, thereby effectively preventing the problem of residual rainwater dripping outward or wetting objects.

[0041] 2. More convenient operation

[0042] Through the opening and closing sleeve and the pulling wire mechanism, push and pull operations can be performed directly outside the outer tube, eliminating the tedious process of manually folding or tying the umbrella straps; at the same time, it also avoids direct contact between hands and the wet umbrella surface, thereby improving the comfort of use.

[0043] 3. Keep the appearance neat and beautiful

[0044] Since the umbrella and the tail are wrapped in the outer tube after being folded, only a relatively slender tube body is shown on the outside, and the overall visual effect is simple; there is no cramped or messy feeling of the umbrella and the frame spreading outward. It is especially suitable for users who pursue fashion or business style.

[0045] 4.Stable structure, easy to maintain

[0046] Compared with multi-fold umbrellas, the "straight bone" structure has fewer parts, a simpler movement trajectory, and is easier to inspect or replace parts; it is easy to maintain good coaxiality and smoothness during the process of folding and opening the umbrella.

[0047] 5. Expanded design and extension space

[0048] Since the basic mode of "outer tube + pull wire + opening and closing sleeve" can be combined with subsequent improvement or expansion plans (such as setting windproof lines, positioning parts, elastic buckles, etc.), there is room for further improvement in windproof, automatic opening and closing, appearance and other aspects to meet more differentiated usage needs.

[0049] In summary, in one implementation, by setting the technical features of the outer tube, opening and closing sleeve, connecting rod, upper nest, lower nest, ribs and pull wire, the function of smoothly pulling the umbrella and ribs and hiding them inside the outer tube when the umbrella is closed is realized, which directly solves the problem in the prior art that "the umbrella or bead tail is exposed to the outside after folding, which is easy to wet the surrounding environment or affect the appearance". At the same time, with the simple and clear straight rib structure and pull wire transmission method, it has achieved significant beneficial effects in terms of ease of operation, waterproofness and neat appearance, and has good practical value and promotion prospects.

[0050] In general, this solution can cleverly store the umbrella cloth, umbrella ribs, honeycombs, bead tails, and umbrella tails that are exposed outside into the tube without affecting the normal opening and closing functions of the umbrella, thereby achieving neatness, beauty, and safety performance; it can better achieve the effect that after using the umbrella on rainy days, people can first enter the car or room and then close the umbrella without getting the contact objects wet, thereby improving the user experience.

[0068] In order to further explain the technical solution of the present invention, the following will be described in detail with reference to the drawings in the embodiments of the present invention. It should be understood that the embodiments described here are only part of the embodiments of the present invention, not all of them, and are not intended to limit the present application.

[0069] like Figure 1 to Figure 17 As shown, in an embodiment of the present invention, a straight-bone umbrella with a hidden umbrella cover is provided, in which the umbrella cover, umbrella ribs, bead tail, honeycomb, and umbrella tail can be hidden inside the middle rod, so as to effectively prevent the bead tail or umbrella tail from accidentally bruising others, and to achieve neatness, beauty, environmental protection, and convenience in carrying.

[0070] A second object of the present invention is to provide a device that can effectively prevent residual rainwater from wetting contact objects after use in rainy days.

[0071] The third purpose of the present invention is to provide a cane umbrella with increased variability in appearance and function, which can be used in conjunction with a cane to achieve a dual-use effect; of course, it is also easier to achieve by adding electric lights, lighting, fans, etc.

[0072] Figure 1-Figure 4 is a schematic structural diagram of the first embodiment of the present invention, Figure 1 The umbrella is in the closed state. It can be clearly seen in the figure that the umbrella ribs and umbrella cover are retracted into the hollow tube. Figure 1 It can be seen that a top sleeve 1111 is provided on the upper part of the outer tube 2, and a pulley is provided inside the top sleeve 1111; an umbrella handle 4 is provided on the lower part of the outer tube 2, and a pulley is provided inside the umbrella handle 4; the outer wall of the outer tube 2 is sleeved with the opening and closing sleeve 3; at this time, the opening and closing sleeve 3 is at the upper part of the outer tube 2 and also at the lower end of the top sleeve 1111. Figure 1 It can be seen that the linkage plug 14 is arranged at the lower end inside the outer tube 2, and the upper part of the linkage plug 14 is connected to the lower end of the connecting rod 12, and the upper end of the connecting rod 12 passes through the inner hole of the lower nest 11 and is connected to the upper nest 10, so that the lower nest 11 is sleeved on the connecting rod 12 for up and down movement; in addition, the first joint 16b at one end of the long bone 16 is connected to the upper nest 10, and then the other end of the long bone 16 is sleeved with the bead tail 15, and finally the middle butterfly 16a of the long bone 16 is connected to the second joint 17a at one end of the short bone 17; at this time, the third joint 17b at the other end of the short bone 17 is connected to the lower nest 11; and the umbrella cloth 20 is sewn on the long bone 16, the tail of the umbrella cloth 20 is fixed by the bead tail 15, and the center of the umbrella cloth 20 is fixed by the umbrella tail 21 and the upper nest 10. The umbrella cloth 20, the umbrella tail 21, the long bone 16, the bead tail 15, the short bone 17, the upper nest 10, the lower nest 11, the connecting rod 12, and the linkage plug 14 are connected together to serve as a whole that restricts displacement of each other.

[0073] One end 512 of the opening line 51 is connected to the linkage plug 14, and the other end goes around the lower nest 11 and the upper nest 10 upwards, then goes around the pulley 7 of the top cover 1111, and then goes down to connect to one end 511 of the opening and closing cover 3; one end 522 of the closing line 52 is connected to the linkage plug 14, and the other end goes around the pulley 8 of the umbrella handle 4 downwards, and then goes up to connect to 521 of the opening and closing cover 3. Through the above connection, an integral body that can open and close the umbrella is formed.

[0074] like Figure 2 In the process of opening the umbrella shown in the figure, the opening and closing sleeve 3 is pulled downward by hand. Because the opening and closing sleeve 3 is connected to one end 511 of the opening line 51, the opening line 51 will be pulled out from the inside of the outer tube 2 on the pulley 7 of the top sleeve 1111, and the other end 512 of the opening line 51 is connected to the linkage plug 14. When the opening line 51 is pulled out from the pulley 7, the linkage plug 14 will also be pulled upward; because the linkage plug 14 is connected to the connecting rod 12, the connecting rod 12 is connected to the upper nest 10, the upper nest 10 is connected to the long bone 16, the umbrella cloth 20, the umbrella tail 21, and the bead tail 15, the long bone 16 is connected to the short bone 17, and the short bone 17 is connected to the lower nest 11. They are connected to each other, and when the linkage plug 14 moves upward, the others will also move upward at the same time; until the limiting protrusion 11a of the lower nest 11 is contacted and positioned by the limiting part 1111a of the top sleeve 1111, the displacement change of the umbrella assembly will occur.

[0075] like Figure 3 As shown in the process of opening the umbrella, the limiting protrusion 11a of the lower nest 11 is contacted and positioned by the limiting portion 1111a of the top cover 1111, and the lower nest 11 can no longer move upward. Although the lower nest 11 is restricted and cannot move, the umbrella opening line 51 will still pull the linkage plug 14 to move upward, so that the linkage plug 14 pushes the connecting rod 12 to pass through the inner hole of the lower nest 11 and continue to move upward, so that the upper nest 10 moves away from the lower nest 11 and also moves upward, until the upper part of the linkage plug 14 contacts the lower nest part, and the linkage plug 14 stops moving. At this time, the upper nest 10 and the lower nest 11 are spaced apart, and the umbrella is in an open state, as shown in FIG. Figure 4 shown.

[0076] exist Figure 4When the umbrella is in the open state, if the umbrella is folded at this time, the process is similar to that of opening the umbrella. At this time, the opening and folding sleeve 3 is already at the lower part of the outer tube 2. The opening and folding sleeve 3 is pulled upward by hand. Because the opening and folding sleeve 3 is connected to one end 521 of the folding line 52, the opening and folding sleeve 3 will pull the folding line 52 out of the outer tube 2 on the pulley 8 of the umbrella handle 4 when it moves upward, and the other end 522 of the folding line 52 is connected to the linkage plug 14, and the linkage plug 14 will also be pulled downward; the linkage plug 14 indirectly pulls the connecting rod 12, and the connecting rod 12 indirectly pulls the upper nest 10 and the lower nest 11, and indirectly pulls the long bone 16, the short bone 17, the umbrella cloth 20, the umbrella tail 21, and the bead tail 15 together to be pulled into the inner part of the outer tube 2, thereby achieving the purpose of folding the umbrella and successfully hiding the umbrella cloth.

[0077] It should be noted that there can be one or more opening and closing lines 51 and 52 in one umbrella. For a clearer illustration, only one opening line and one closing line are shown in the figure. The actual optimal number is two opening and closing lines 51 and two closing lines 52 for a balanced effect. Figure 1-Figure 4 .

[0078] Figure 5-Figure 9 It is a structural schematic diagram of implementation mode 2 of the present invention.

[0079] Figure 5 1 is a schematic diagram of the local structure of a honeycomb according to an embodiment of the present invention. This figure shows a change in the lower nest 11 of the first embodiment. It can be seen from the left figure that the original lower nest 11 and the original limiting protrusion 11a are integrated; while in the right figure, the integrated lower nest is divided into two parts, namely the lower nest part 111 and the positioning member 9. The inner hole of the positioning member 9 can be inserted into the lower part of the lower nest part 111 and allow up and down movements. It should be noted that the inner hole of the positioning member 9 is not limited to the inside, and can also be a side groove or a side hole. Usually, it is better to make it into an inner hole; and the inner lower edge of the positioning member 9 is also provided with an inclined surface 9a; at the same time, the positioning member 9 is provided with a connection point 612 for connecting the windproof line 61, and the number of windproof lines 61 provided can be determined according to the number of umbrella ribs; as shown in the right figure, an elastic buckle 13 is provided in the middle of the connecting rod 121, which can be pressed by the inclined surface 9b of the positioning member 9, so that the elastic buckle 13 is completely pushed into the connecting rod 121 from a state of partially protruding from the connecting rod 121.

[0080] Figure 6-Figure 9 It is a schematic diagram of the structural position of the opening and closing process of the second embodiment of the present invention.

[0081] Figure 6 Schematic diagram of the position of the folded umbrella structure of the second embodiment of the present invention. The connection method is almost the same as the first embodiment except for the newly added positioning member 9, windproof line 61 and elastic buckle 13.

[0082] Figure 6It can be seen that the linkage plug 141 is arranged at the lower end of the outer tube 22, and the upper part of the linkage plug 141 is connected to the lower end of the connecting rod 121, and the upper end of the connecting rod 121 passes through the inner hole of the lower nest 111 and is connected to the upper nest 101, so that the lower nest 111 is sleeved on the connecting rod 121 and moves up and down; the lower part of the lower nest 111 is sleeved with the positioning piece 9, and moves up and down at the lower part of the lower nest 111; one end 612 of the windbreak line 61 is connected to the positioning piece 9, and the other end passes upward from the lower nest 111 and the upper nest 101 and connects to the tail of the long bone 161 The windproof line 61 is always in a tensioned state; in addition, the first joint 161b at one end of the long bone 161 is connected to the upper nest 101, and then the other end of the long bone 161 is sleeved with the bead tail 151, and finally the middle butterfly 161a of the long bone 161 is connected to the second joint 171a at one end of the short bone 171; at this time, the third joint 171b at the other end of the short bone 171 is connected to the lower nest 111; and the umbrella cloth 20 is sewn on the long bone 161, the tail of the umbrella cloth 20 is fixed by the bead tail 151, and the center of the umbrella cloth 20 is fixed by the umbrella tail 211 and the upper nest 101. So that the umbrella cloth 20, the umbrella tail 211, the long bone 161, the bead tail 151, the short bone 171, the windproof line 61, the upper nest 101, the lower nest 111, the positioning member 9, the connecting rod 121, the elastic buckle head 13, and the linkage plug 141 are connected together to play a role in limiting the displacement of each other.

[0083] One end 532 of the opening line 53 is connected to the linkage plug 141, and the other end goes around the lower nest 111 and the upper nest 101 upwards, then goes around the pulley 71 of the top cover 2222, and then goes down to connect to one end 531 of the opening and closing cover 31; one end 542 of the closing line 54 is connected to the linkage plug 141, and the other end goes around the pulley 81 of the umbrella handle 41 downwards, and then goes up to connect to 541 of the opening and closing cover 31. After the above connection, an integral body that can open and close the umbrella is formed.

[0084] like Figure 7In the process of opening the umbrella as shown, the opening and closing sleeve 31 is pulled downward by hand, and because one end 531 of the opening and closing sleeve 31 is connected to the opening line 53, the opening line 53 will be pulled out from the inside of the outer tube 22 on the pulley 71 of the top sleeve 2222, and the other end 532 of the opening line 53 is connected to the linkage plug 141. When the opening line 53 is pulled out from the pulley 71, the linkage plug 141 will also be pulled to move upward; because the linkage plug 141 is connected to the connecting rod 121, the connecting rod 12 is connected to the upper nest 101 and the elastic buckle 13, the upper nest 101 is connected to the long bone 161, the umbrella cloth 20, the umbrella tail 211, the bead tail 151, the long bone 161 is connected to the short bone 171, the short bone 171 is connected to the lower nest part 111, the lower nest part 111 is sleeved with the positioning member 9, and the positioning member 9 is connected to the windproof line 61. They are connected to each other, and when the linkage plug 141 moves upward, the others will also move upward at the same time; until the limiting protrusion 9a of the positioning member 9 is contacted and positioned by the limiting portion 2222a of the top sleeve 2222, the displacement of the umbrella assembly will change.

[0085] like Figure 8 In the process of opening the umbrella, after the limiting protrusion 9a and the limiting portion 2222a contact and position with each other, the displacement of the umbrella assembly changes as follows; when the limiting protrusion 9a of the positioning member 9 is contacted and positioned by the limiting portion 2222a of the top cover 2222, the positioning member 9 can no longer move upward. Although the positioning member 9 is restricted from moving, the opening line 53 still pulls the linkage plug 141 to move upward, so that the linkage plug 141 pushes the connecting rod 121 to pass through the inner hole of the lower nest 111 and continue to move upward, so that the upper The nest 101 moves upward away from the lower nest 111. When the connecting rod 121 moves upward a certain distance, the upper end of the elastic buckle 13 inside it will support the lower nest 111 to move upward again. Because the lower nest 111 moves upward, a distance is created between it and the positioning member 9. As mentioned above, the windproof line 61 is already in a tensioned state between one end 611 and the other end 612 of the windproof line 61. At this time, a distance is created between the lower nest 111 and the positioning member 9, forcing the windproof line 61 to pull the long bone 16 to bend.

[0086] It should be noted that the purpose of bending the long bone 161 is to assist the umbrella to open successfully, because the distance of the umbrella cloth 20 around the circle is usually designed to be shorter than the distance of each rib around the circle, so that the umbrella will have a beautiful curvature; and the distance of the umbrella cloth 20 is shorter than the distance of the ribs, and the structure of this implementation is reverse opening, so it is necessary to bend the long bone 161 before the umbrella is fully opened. It should be mentioned that if there is no action of forcing the windproof line 61 to pull the long bone 16 to bend and the corresponding elastic buckle head 13 structure, it is easy to cause the umbrella to bend reversely and cover the buckle toward the sky.

[0087] Figure 8As shown in the figure: when the long bone 161 is bent, the opening line 53 continues to pull the linkage plug 141 and the connecting rod 121 to move upward. When the elastic buckle 13 in the middle of the connecting rod 121 is pressed by the inclined surface 9b of the positioning member 9, the support to the lower nest 11 can be released. After the support is gone, the linkage plug 141 continues to move upward and finally contacts the lower part of the positioning member 9 before stopping. At this time, the upper nest 101 and the lower nest 111 have a sufficient distance, and the windproof line 61 also bends the umbrella ribs to form an open state of the umbrella, as shown in the figure. Fig. 9 shown.

[0088] exist Fig. 9 When the umbrella is in the open state, it is necessary to fold the umbrella, and the process is similar to that of opening the umbrella. At this time, the opening and folding sleeve 31 is already at the lower part of the outer tube 22. The opening and folding sleeve 31 is pulled upward by hand. Because the opening and folding sleeve 31 is connected to one end 541 of the folding line 54, the opening and folding sleeve 31 will pull the folding line 54 out of the outer tube 22 on the pulley 81 of the umbrella handle 41 when it moves upward, and the other end 542 of the folding line 54 is connected to the linkage plug 141, and the linkage plug 141 will also be pulled downward; the linkage plug 141 indirectly pulls the connecting rod 121, and the connecting rod 121 indirectly pulls the upper nest 101, the elastic buckle head 13, the lower nest part 111 and the positioning member 9, and indirectly pulls the long bone 161, the short bone 171, the umbrella cloth 20, the umbrella tail 211, and the bead tail 151 together to be pulled into the inner part of the outer tube 22, thereby achieving the purpose of folding the umbrella and successfully hiding the umbrella cloth.

[0089] Figure 10-Figure 16 It is a structural schematic diagram of implementation mode 3 of the present invention.

[0090] Fig.10 Schematic diagram of the local structure of the top cover of the embodiment of the present invention. This figure shows a change of the top cover 2222 of the second embodiment. It can be seen from the left figure that the original top cover 2222 is relatively short; while the top cover 3333 in the right figure is relatively high and shaped like a trumpet. The purpose of setting it into a trumpet shape is to reduce the friction when the umbrella is folded, so that the umbrella cloth can enter the outer tube 23 more easily.

[0091] Fig.11 This is a partial structural diagram of a positioning member in an embodiment of the present invention. This figure shows a change in the positioning member 9 of the second embodiment. In the left figure, it can be seen that the original positioning member 9 is relatively short; while in the right figure, the positioning member 91 is relatively high and a space is set at the bottom, so that the outer wall of the linkage plug 142 can fit with the inner wall of the positioning member 91 to form a sliding fit with each other. The higher positioning member 91 is used in conjunction with the higher top sleeve 3333.

[0092] Figure 12-16 Schematic diagram of the structural position of the opening and closing process of the third embodiment of the present invention

[0093] Fig.12It can be seen that the linkage plug 142 is arranged at the lower end of the outer tube 23, and the upper part of the linkage plug 142 is connected to the lower end of the connecting rod 122, and the upper end of the connecting rod 122 passes through the inner hole of the lower nest 112 and is connected to the upper nest 102, so that the lower nest 112 is sleeved on the connecting rod 122 and moves up and down; the lower part of the lower nest 112 is sleeved on the positioning piece 91, and moves up and down at the lower part of the lower nest 112; one end 622 of the windbreak line 62 is connected to the positioning piece 91, and the other end passes upward from the lower nest 112 and the upper nest 102 and connects to the tail of the long bone 162 621, the windproof line 62 is always in a tensioned state; in addition, the first joint 162b at one end of the long bone 162 is connected to the upper nest 102, and then the other end of the long bone 162 is sleeved with the bead tail 152, and finally the middle butterfly 162a of the long bone 162 is connected to the second joint 172a at one end of the short bone 172; at this time, the third joint 172b at the other end of the short bone 172 is connected to the lower nest 112; and the umbrella cloth 20 is sewn on the long bone 162, the tail of the umbrella cloth 20 is fixed by the bead tail 152, and the center of the umbrella cloth 20 is fixed by the umbrella tail 212 and the upper nest 102. So that the umbrella cloth 20, the umbrella tail 212, the long bone 162, the bead tail 152, the short bone 172, the windproof line 62, the upper nest 102, the lower nest 112, the positioning member 91, the connecting rod 122, the elastic buckle head 131, and the linkage plug 142 are connected together to play a role in limiting the displacement of each other.

[0094] As shown, one end 552 of the opening line 55 is connected to the linkage plug 142, and the other end goes around the top of the positioning member 91 upwards, then goes around the side of the lower nest 112 and the upper nest 102, then goes around the pulley 72 of the top cover 3333, then goes around the pulley 18 of the opening and closing cover 32 downwards, and then goes up to 551 of the top cover 3333; one end 562 of the closing line 56 is connected to the linkage plug 142, and the other end goes around the pulley 82 of the umbrella handle 42 downwards, then goes around the pulley 19 of the opening and closing cover 32 upwards, and then goes down to one end 561 of the umbrella handle 42. After the above connection, an integral body that can open and close the umbrella is formed.

[0095] like Fig.13In the process of opening the umbrella shown in the figure, the opening and closing sleeve 32 is pulled downward by hand. Because the opening and closing sleeve 32 is provided with a pulley 18 around which the opening line 55 is wound, the opening line 55 will pull out double the line from the inside of the outer tube 23 on the pulley 72 of the top sleeve 3333, thereby reducing the distance that the opening and closing sleeve 32 moves when opening the umbrella; the other end 552 of the opening line 553 is connected to the linkage plug 142, and when the opening line 55 is pulled out from the pulley 72, the linkage plug 142 will also be pulled to move upward; because the linkage plug 142 is connected to the connecting rod 122, the connecting rod 122 is connected to the upper nest 102 and the elastic buckle head 131, the upper nest 102 is connected to the long bone 162, the umbrella cloth 20, the umbrella tail 212, the bead tail 152, the long bone 162 is connected to the short bone 172, the short bone 172 is connected to the lower nest 112, the lower nest 112 is sleeved with the positioning member 91, and the positioning member 91 is connected to the windproof line 62. They are connected to each other, and when the linkage plug 142 moves upward, the others will also move upward at the same time; until the limiting protrusion 91a of the positioning member 91 is contacted and positioned by the limiting portion 3333a of the top sleeve 3333, the umbrella assembly will not change its displacement.

[0096] like Fig.14 In the process of opening the umbrella, after the limiting protrusion 91a and the limiting portion 3333a contact and position each other, the displacement of the umbrella assembly changes as follows: when the limiting protrusion 91a of the positioning member 91 is contacted and positioned by the limiting portion 3333a of the top sleeve 3333, the positioning member 91 can no longer move upward. Although the positioning member 91 is restricted from moving, the opening line 55 still pulls the linkage plug 142 to move upward, so that the linkage plug 142 pushes the connecting rod 122 to pass through the inner hole of the lower nest 112 and continue to move upward, so that The upper nest 102 moves away from the lower nest 112 and also moves upward. When the connecting rod 122 moves upward for a certain distance, the upper end of the elastic buckle 131 inside it will push the lower nest 112 upward again. Because the lower nest 112 moves upward, it creates a distance from the positioning piece 91. As mentioned above, the windproof line 621 of the long bone 162 and one end 622 of the windproof line 61 are already in a tensioned state. At this time, the lower nest 112 and the positioning piece 91 create a distance again, forcing the windproof line 621 to pull the long bone 162 to bend.

[0097] It should be noted that the purpose of bending the long ribs is to assist the umbrella to open successfully, because usually the distance of the umbrella cloth around the circle is designed to be shorter than the distance of each rib around the circle, so that the umbrella will have a beautiful curvature; and the distance of the umbrella cloth is shorter than the distance of the ribs, and the structure of this implementation is a reverse opening, so it is necessary to bend the long ribs before the umbrella is fully opened.

[0098] Fig.14As shown in the figure: when the long ribs are bent, the opening line 55 continues to pull the linkage plug 142 and the connecting rod 122 to move upward. When the elastic buckle 131 in the middle of the connecting rod 122 is pressed by the inclined surface 91b of the positioning member 91, the support to the lower nest 112 can be released. After the support is removed, the linkage plug 142 continues to move upward and finally contacts the lower part of the positioning member 91 before stopping. At this time, the upper nest 102 and the lower nest 112 have a sufficient distance, and the windproof line 62 also bends the umbrella ribs to form an open state of the umbrella, as shown in the figure. Fig.15 shown.

[0099] exist Fig.15 When the umbrella is in the open state, it is necessary to fold the umbrella, and the process is similar to that of opening the umbrella. At this time, the opening and folding sleeve 32 is already at the lower part of the outer tube 23. The opening and folding sleeve 32 is pulled upward by hand. Because the pulley 19 of the opening and folding sleeve 32 is wound around the umbrella folding line 56, when the opening and folding sleeve 32 moves upward, the umbrella folding line 56 will be pulled out from the pulley 82 of the umbrella grip 42 to the inside of the outer tube 23, and the other end 562 of the umbrella folding line 56 is connected to the linkage plug 142, and the linkage plug 142 will also be pulled downward; the linkage plug 142 indirectly pulls the connecting rod 122, and the connecting rod 122 indirectly pulls the upper nest 102, the elastic buckle head 131, the lower nest 112 and the positioning member 91, and indirectly pulls the long bone 162, the short bone 172, the umbrella cloth 20, the umbrella tail 212, and the bead tail 152 together to be pulled into the inner part of the outer tube 23, thereby achieving the purpose of folding the umbrella and successfully hiding the umbrella cloth.

[0100] It should be noted that the elastic buckle head 131 in the middle of the connecting rod 122 can be an elastic bow piece, a marble plus an elastic piece, a marble plus a steel wire bow, a buckle piece plus a spring, or any other elastic piece with the functions of pressing and releasing and rebounding.

[0101] Fig.16 Schematic diagrams of various rib structures of embodiments of the present invention: the first one illustrates that the long bone and the short bone can be matched with the upper nest and the lower nest in reverse, that is, the short bone is matched with the upper nest and the long bone is matched with the lower nest; the second one illustrates that the middle butterfly of the long bone can also be movable; the third one illustrates that the long bone and the short bone can be matched sideways; the fourth one illustrates that the short bone and the long bone can be matched in one, two or more ways; it should be understood that the structure of this invention patent can be matched with various rib methods of the prior art and is not used to limit the present application.

[0102] Fig.17Schematic diagrams of various windproof line structures of the embodiments of the present invention: the first one shows that one end of the windproof line is connected to the tail of the long bone, and the other end bypasses the pulley on the positioning piece and then connects to the lower nest upward; the second one shows that one end of the windproof line is connected to the tail of the long bone, and the other end bypasses the pulley on the lower nest and then connects to the positioning piece downward; the third one shows that one end of the windproof line is connected to the tail of the long bone, and the other end first bypasses the short bone, then bypasses the pulley on the lower nest, and then connects to the positioning piece downward; the fourth one shows that one end of the windproof line is connected to the tail of the long bone, and the other end first bypasses the lead-out piece on the long bone, then bypasses the pulley on the lower nest, and then connects to the positioning piece downward. Since the windproof pull line has a pulling function during the opening and closing process; therefore, the pull line can be any one of a plastic line, a nylon line, a metal line, or other steel lines, fiber lines, and carbon fiber lines with a certain strength. However, a basic requirement for the pull line is to have sufficient strength and be able to cooperate smoothly during the use of the pull line. It should be understood that there are many ways to wind the windproof line of this invention patent structure, and there are also many materials, but it is not used to limit this application.
