Abstract
Description
Technical Field
[0001] This application relates to the field of umbrella technology, and in particular to an umbrella rib structure and umbrella. Background Technology
[0002] During the closing process, users need to manually roll the umbrella fabric around the outer edge of the central pole and secure it with straps, which is quite tedious. Additionally, after using the umbrella in the rain, water remains on the fabric, inevitably causing users to come into contact with water while closing it, thus reducing the user experience. Utility Model Content
[0003] Therefore, it is necessary to provide an umbrella rib structure and umbrella equipment that enables automatic roll-up of the umbrella fabric without the need for manual handling. At the same time, users will not come into contact with water during the umbrella roll-up process, which helps to improve the user experience.
[0004] Firstly, this application provides an umbrella rib structure, comprising:
[0005] mid-stick;
[0006] The upper nest, the inner nest, and the lower nest are provided. The upper nest is fixed to one end of the middle rod. The inner nest is movably sleeved on the middle rod and can move along the axial direction of the middle rod and rotate about the axial direction of the middle rod. The lower nest is sleeved on the inner nest and can move along the axial direction of the middle rod.
[0007] The main umbrella rib and the main support rib, one end of the main umbrella rib is rotatably connected to the upper nest, one end of the main support rib is slidably and rotatably connected to the main umbrella rib, and the other end of the main support rib is rotatably connected to the lower nest;
[0008] Secondary umbrella ribs and secondary support ribs, one end of the secondary umbrella ribs being rotatably connected to the upper nest, one end of the secondary support ribs being slidably and rotatably connected to the secondary umbrella ribs, and the other end of the secondary support ribs being rotatably connected to the inner nest; and
[0009] A drive assembly includes a pull cord, a portion of which is wound around the outer periphery of the inner nest. A portion of the pull cord away from the inner nest is connected to the lower nest. When the lower nest moves away from the upper nest along the axial direction of the center rod, the pull cord drives the inner nest to rotate around the axial direction of the center rod, thereby causing the umbrella fabric connected to the main umbrella rib to be rolled between the center rod and the secondary umbrella rib.
[0010] In one embodiment, the drive assembly further includes a kit fitted onto the inner nest, the kit having a wire guide groove, and the end of the pull cord away from the inner nest passing through the wire guide groove and connecting to the lower nest.
[0011] In one embodiment, the length direction of the through groove is tangent to the radial direction of the central rod.
[0012] In one embodiment, the outer peripheral surface of the inner nest is provided with a first limiting portion and a second limiting portion, the first limiting portion and the second limiting portion being spaced apart along the axial direction of the central rod; the kit is provided with a first abutting portion and a second abutting portion, the first abutting portion abutting against the first limiting portion and the second abutting portion abutting against the second limiting portion, so as to restrict the movement of the kit relative to the inner nest along the axial direction of the central rod.
[0013] In one embodiment, one of the outer peripheral surface of the kit and the inner peripheral surface of the lower nest is provided with a guide groove, the extension direction of the guide groove being parallel to the axial direction of the middle rod; the other of the outer peripheral surface of the kit and the inner peripheral surface of the lower nest is provided with a guide rail, the extension direction of the guide rail being parallel to the axial direction of the middle rod, the guide rail being disposed in the guide groove and slidingly engaging with the guide groove.
[0014] In one embodiment, the wire guide groove is located at the bottom of the guide groove on the side near the upper nest, the wire guide groove is connected to the guide groove, and the end of the pull rope away from the inner nest passes through the wire guide groove and is located in the guide groove.
[0015] In one embodiment, the drive assembly further includes an elastic element fitted onto the inner nest and located between the inner nest and the kit. One end of the elastic element is connected to the inner nest, and the other end of the elastic element is connected to the kit. The elastic element is used to drive the inner nest to rotate about the axial direction of the central rod.
[0016] In one embodiment, the secondary umbrella rib is provided with a secondary connector, which is movable along the axial direction of the secondary umbrella rib toward or away from the upper nest, and the secondary support rib is rotatably connected to the secondary connector; the secondary umbrella rib is provided with a first limiting member, which is located on the side of the secondary connector away from the upper nest; the inner nest is moved along the axial direction of the center rod toward away from the upper nest, so that the secondary umbrella rib has a limit closed position; at the limit closed position, the secondary connector abuts against the first limiting member, the secondary umbrella rib closes, and a clearance space is reserved between the main umbrella rib and the secondary umbrella rib for the secondary umbrella rib to roll up the umbrella fabric.
[0017] In one embodiment, the secondary umbrella rib is further provided with a second limiting member, which is located between the upper nest and the secondary connecting member; the inner nest and the lower nest move along the axial direction of the center rod toward the upper nest, so that the main umbrella rib and the secondary umbrella rib are in an open state; in the open state, the secondary connecting member abuts against the second limiting member.
[0018] In one embodiment, there are multiple main ribs and multiple secondary ribs, and all the main ribs and secondary ribs are arranged alternately along the circumference of the upper canopy, with the length of the main ribs being greater than the length of the secondary ribs.
[0019] Secondly, this application provides an umbrella, including an umbrella fabric and the aforementioned umbrella rib structure, wherein the umbrella fabric is laid on the main umbrella rib and the secondary umbrella rib.
[0020] In the aforementioned umbrella rib structure and fittings, when the umbrella is closed, while the secondary ribs are in the closed position but the main ribs are not yet closed, they continue to move along the axis of the center rod away from the upper canopy, causing the main ribs to continue closing. Since the pull cord is wrapped around the outer circumference of the inner canopy, with its end connected to the lower canopy, the lower canopy pulls the pull cord during the closing of the main ribs, causing the inner canopy to rotate around the axis of the center rod. This, in turn, causes the secondary ribs to curl the umbrella fabric, completing the automatic roll-up of the fabric. This eliminates the need for manual adjustment of the umbrella fabric, and prevents the user from coming into contact with water during the closing process, thus improving the user experience.

[0030] To make the above-mentioned objectives, features, and advantages of this application more apparent and understandable, the specific embodiments of this application are described in detail below with reference to the accompanying drawings. Many specific details are set forth in the following description to provide a thorough understanding of this application. However, this application can be implemented in many other ways different from those described herein, and those skilled in the art can make similar modifications without departing from the spirit of this application. Therefore, this application is not limited to the specific embodiments disclosed below.
[0031] The umbrella provided in one embodiment of this application may be a rain umbrella, a sun umbrella, etc., but is not limited thereto.
[0032] In one embodiment, see Figure 1 The umbrella includes an umbrella fabric and an umbrella rib structure 20. The umbrella fabric is located on the umbrella rib structure 20 and is used for rain and sun protection, while the umbrella rib structure 20 is used to support the umbrella fabric.
[0033] Further, see Figure 1 The umbrella rib structure 20 includes a central rod 21, an upper nest 22, an inner nest 23, and a lower nest 24. The upper nest 22 is fixed to one end of the central rod 21. The inner nest 23 is movably fitted onto the central rod 21, and the inner nest 23 can move along the axial direction of the central rod 21 and rotate about the axial direction of the central rod 21. The lower nest 24 is fitted onto at least a portion of the inner nest 23, for example, the lower nest 24 is fitted onto the lower part of the inner nest 23, and the lower nest 24 can move along the axial direction of the central rod 21. It is understood that the inner nest 23 and the lower nest 24 are cylindrical sliding structures. By moving the inner nest 23 and the lower nest 24 along the axial direction of the central rod 21, the umbrella can be opened and closed. By rotating about the axial direction of the central rod 21 as the center of rotation, the umbrella fabric can be rolled up, realizing the automatic roll-up of the umbrella fabric.
[0034] See Figure 1 and Figure 2The umbrella rib structure 20 also includes a main umbrella rib 25 and a main support rib 26. One end of the main umbrella rib 25 is rotatably connected to the upper canopy 22. One end of the main support rib 26 is rotatably connected to the main umbrella rib 25, and the other end of the main support rib 26 is rotatably connected to the lower canopy 24. The umbrella fabric is laid on the main umbrella rib 25, and the main umbrella rib 25 is used to support the umbrella fabric.
[0035] Specifically, see Figure 1 The main umbrella rib 25 is provided with a main connector 251, and the main support rib 26 is rotatably connected to the main connector 251. For example, see Figure 2 The main connector 251 has a first ear 2511 and a second ear 2512 spaced apart, and both the first ear 2511 and the second ear 2512 have a first connecting hole. One end of the main support bone 26 has a first connecting ear, and the first connecting ear has a second connecting hole. The first connecting ear is located between the first ear 2511 and the second ear 2512, and a first connecting shaft is provided in both the first connecting hole and the second connecting hole. In this way, the main support bone 26 and the main umbrella bone 25 are hinged.
[0036] See Figure 1 The umbrella rib structure 20 also includes a secondary rib 27 and a secondary support rib 28. One end of the secondary rib 27 is rotatably connected to the upper nest 22. One end of the secondary support rib 28 is slidably and rotatably connected to the secondary rib 27, and the other end of the secondary support rib 28 is rotatably connected to the inner nest 23. The secondary rib 27 is used to roll up the umbrella fabric when closing the umbrella, thus eliminating the need for manual adjustment of the fabric.
[0037] Specifically, see Figure 1 The secondary rib 27 is provided with a secondary connector 271, which is movable along the axial direction of the secondary rib 27 toward or away from the upper nest 22. The secondary support rib 28 is rotatably connected to the secondary connector 271. For example, see Figure 2 The secondary connector 271 has a spaced-apart third ear 2711 and a fourth ear 2712, both of which have a third connecting hole. One end of the secondary support rib 28 has a second connecting ear, which has a fourth connecting hole. The second connecting ear is located between the third ear 2711 and the fourth ear 2712, and both the third and fourth connecting holes contain a second connecting shaft. This allows for a sliding and rotatable connection between the secondary support rib 28 and the secondary umbrella rib 27.
[0038] In one embodiment, see Figure 1 The lengths of the main rib 25 and the secondary rib 27 are not equal. Optionally, the length of the main rib 25 is greater than the length of the secondary rib 27. It should be noted that the difference in length between the main rib 25 and the secondary rib 27 determines the sliding distance of the inner nest 23 and the lower nest 24.
[0039] Further, see Figure 1 and Figure 2 The secondary umbrella rib 27 is provided with a first limiting member 2713, which is located on the side of the secondary connector 271 away from the upper nest 22. Thus, by providing the first limiting member 2713 on the secondary umbrella rib 27, the first limiting member 2713 can limit the distance that the secondary connector 271 can move away from the upper nest 22 during the umbrella closing process.
[0040] Further, see Figure 1 and Figure 2 The inner rib 23 moves away from the upper rib 22 along the axial direction of the middle rod 21 so that the secondary rib 27 has the ultimate closed position. In the ultimate closed position, the secondary connector 271 abuts against the first limiting member 2713, the secondary rib 27 closes, and a clearance space is reserved between the main rib 25 and the secondary rib 27 for the secondary rib 27 to roll up the umbrella fabric.
[0041] When closing the umbrella, refer to Figure 1 and Figure 2 An external force acts on the lower canopy 24, causing the inner canopy 23 and the lower canopy 24 to move away from the upper canopy 22 along the axial direction of the center rod 21, which in turn causes the main rib 25 and the secondary rib 27 to close the canopy fabric. When the secondary connector 271 abuts against the first limiting member 2713, the secondary rib 27 reaches its maximum closing position and is in a closed state. Since the length of the main rib 25 is greater than the length of the secondary rib 27, when the secondary rib 27 reaches its maximum closing position, the main rib 25 has not yet reached the closed state, meaning there is clearance space between the main rib 25 and the secondary rib 27 for the secondary rib 27 to roll up the canopy fabric.
[0042] In one embodiment, see Figure 1 , Figure 3 and Figure 4 The umbrella rib structure 20 also includes a drive assembly 29. The drive assembly 29 includes a pull cord 291, a portion of which is wound around the outer periphery of the inner nest 23, and a portion of the pull cord 291 away from the inner nest 23 is connected to the lower nest 24. When the lower nest 24 moves away from the upper nest 22 along the axial direction of the center rod 21, the pull cord 291 is used to drive the inner nest 23 to rotate around the axial direction of the center rod 21, so as to drive the umbrella fabric to be rolled between the center rod 21 and the secondary umbrella rib 27.
[0043] When closing the umbrella, refer to Figure 1 and Figure 4When the secondary ribs 27 are in the closed state but the main ribs 25 are not yet closed, they continue to move away from the upper canopy 22 along the axis of the center rod 21, and the main ribs 25 continue to close. Since the pull cord 291 is wrapped around the outer circumference of the inner canopy 23, and the end of the pull cord 291 away from the inner canopy 23 is connected to the lower canopy 24, during the closing of the main ribs 25, the lower canopy 24 pulls the pull cord 291, causing the inner canopy 23 to rotate around the axis of the center rod 21, thereby causing the secondary ribs 27 to roll up the canopy fabric, completing the automatic roll-up of the canopy fabric. Thus, there is no need to manually adjust the canopy fabric, and the user will not come into contact with water during the closing process, which improves the user experience.
[0044] When opening the umbrella, refer to Figure 1 and Figure 4 The lower nest 24 is pushed towards the upper nest 22 along the axis of the central rod 21. At the same time, with the help of the elastic potential energy of the canopy fabric rolled by the secondary ribs 27 and the traction of the canopy fabric, the inner nest 23 rotates around the axis of the central rod 21 to retract the pull rope 291 and wrap the pull rope 291 around the inner nest 23. The inner nest 23 returns to the center and the lower nest 24 is pushed towards the upper nest 22 along the axis of the central rod 21 to complete the opening of the umbrella.
[0045] In one embodiment, see Figure 4 and Figure 5 The drive assembly 29 also includes a kit 292, which is fitted onto the inner nest 23. The kit 292 has a wire guide groove 2921, through which the end of the pull rope 291 away from the inner nest 23 passes and connects to the lower nest 24.
[0046] As the main umbrella rib 25 continues to close, the lower nest 24 pulls the pull cord 291. Since the pull cord 291 passes through the thread groove 2921 of the assembly 292, the thread groove 2921 guides the pull cord 291, causing it to move in a predetermined direction to better drive the inner nest 23 to rotate axially around the center rod 21. Furthermore, the thread groove 2921 also serves to avoid interference between the pull cord 291 and the assembly 292.
[0047] Optionally, see Figure 5 The length direction of the guide groove 2921 is tangent to the radial direction of the center rod 21. After the pull rope 291 passes through the guide groove 2921, the pull rope 291 located inside the guide groove 2921 is tangent to the radial direction of the center rod 21. Thus, when the pull rope 291 is pulled away from the upper nest 22 along the axial direction of the center rod 21, the inner nest 23 is subjected to tangential force and rotates around the axial direction of the center rod 21, causing the auxiliary umbrella ribs 27 to curl the umbrella fabric, completing the automatic umbrella fabric closing. This facilitates the smooth rotation of the inner nest 23 around the axial direction of the center rod 21.
[0048] It should be noted that the kit 292 cannot move relative to the inner nest 23 along the axial direction of the central rod 21. For example, see [reference needed]. Figure 4 and Figure 6 The outer peripheral surface of the inner nest 23 is provided with a first limiting part 231 and a second limiting part 232, which are spaced apart along the axial direction of the central rod 21. The assembly 292 is provided with a first abutting part 2922 and a second abutting part 2923, which abut against the first limiting part 231 and the second abutting part 2923 abut against the second limiting part 232 to restrict the movement of the assembly 292 relative to the inner nest 23 along the axial direction of the central rod 21.
[0049] Optionally, see Figure 6 The first limiting part 231 and the second limiting part 232 are limiting flanges. Of course, in other embodiments, the first limiting part 231 and the second limiting part 232 may also be limiting protrusions.
[0050] Since the first limiting part 231 and the second limiting part 232 respectively limit the first abutting part 2922 and the second abutting part 2923, the movement of the kit 292 relative to the inner nest 23 along the axial direction of the central rod 21 can be restricted. This prevents the kit 292 from pulling the pull cord 291 due to displacement along the central rod 21 during the umbrella closing process, thereby preventing the pull cord 291 from accidentally causing the inner nest 23 to rotate around the central rod 21. In addition, by fitting the kit 292 onto the pull cord 291, the kit 292 can protect the pull cord 291, and the reasonable design of the kit 292 helps to simplify the structure.
[0051] It should be noted that the kit 292 cannot rotate relative to the lower nest 24 about the axis of the central rod 21, while the inner nest 23 can rotate relative to the kit 292 about the axis of the central rod 21. For example, see [reference needed]. Figure 6 One of the outer peripheral surface of the kit 292 and the inner peripheral surface of the lower nest 24 is provided with a guide groove 2924, the extension direction of the guide groove 2924 being parallel to the axial direction of the middle rod 21. The other of the outer peripheral surface of the kit 292 and the inner peripheral surface of the lower nest 24 is provided with a guide rail, the extension direction of the guide rail being parallel to the axial direction of the middle rod 21, the guide rail being disposed within the guide groove 2924 and slidingly engaging with the guide groove 2924.
[0052] With this configuration, on the one hand, during the process of the main umbrella rib 25 closing, that is, during the process of the lower nest 24 driving the pull rope 291 to move away from the upper nest 22 along the axis of the middle rod 21, the kit 292 cannot rotate relative to the lower nest 24 around the axis of the middle rod 21. In this way, the pull rope 291 can drive the inner nest 23 to rotate relative to the kit 292 around the axis of the middle rod 21 under the pull of the lower nest 24.
[0053] On the other hand, during the umbrella closing process, the inner nest 23 drives the guide groove 2924 to move up and down along the guide rail. The function of this section is to compensate for the length difference between the main umbrella rib 25 and the secondary umbrella rib 27. After the secondary umbrella rib 27 is closed, the main umbrella rib 25 can continue to close the umbrella until it is completely closed. During the process of the secondary umbrella rib 27 curling the umbrella fabric, elastic deformation will occur, causing the length of the secondary umbrella rib 27 to become shorter. Meanwhile, the inner nest 23 moves along the axis of the center rod 21 towards the upper nest 22, which can compensate for the displacement of the inner nest 23. In addition, through the cooperation of the guide rail and the guide groove 2924, the movement of the inner nest 23 is guided, which helps to improve the stability of the inner nest 23 moving along the axis of the center rod 21, so as to close the umbrella better.
[0054] In this embodiment, refer to Figure 1 and Figure 6 The guide groove 2924 is located on the side of the wire groove 2921 away from the upper nest 22. The guide groove 2924 is connected to the wire groove 2921. The end of the pull rope 291 away from the inner nest 23 passes through the wire groove 2921 and is located in the guide groove 2924.
[0055] Understandably, see Figure 1 and Figure 6 The two groove walls of the guide groove 2924 extend in a direction parallel to the axis of the middle rod 21, and the through groove 2921 is located on the bottom of the guide groove 2924 near the upper nest 22.
[0056] In one embodiment, see Figure 3 and Figure 7 The lower housing 24 is provided with a cable retaining groove 243. The end of the pull rope 291 away from the inner housing 23 is located in the cable retaining groove 243 and engages with it. During installation, the end of the pull rope 291 away from the inner housing 23 is inserted into the cable retaining groove 243. The groove wall of the cable retaining groove 243 clamps the pull rope 291, thus fixing the end of the pull rope 291 away from the inner housing 23 to the lower housing 24. This facilitates the disassembly and assembly of the pull rope 291, and is beneficial for the maintenance and replacement of the pull rope 291.
[0057] Of course, in other embodiments, the end of the pull rope 291 away from the inner nest 23 may be tied to the lower nest 24, or the end of the pull rope 291 away from the inner nest 23 may be welded to the lower nest 24, etc., without limitation.
[0058] In one embodiment, see Figure 4 The drive assembly 29 also includes an elastic element 293. The elastic element 293 is fitted onto the inner nest 23 and located between the inner nest 23 and the kit 292. One end of the elastic element 293 is connected to the inner nest 23, and the other end is connected to the kit 292. During the closing process of the umbrella, the elastic element 293 helps the inner nest 23 rotate around the axis of the center rod 21, facilitating the closing of the umbrella.
[0059] Optionally, see Figure 4 The elastic element 293 is a spiral spring. The spiral spring is sleeved in the inner nest 23, with one end located on the inner side of the spiral spring connected to the inner nest 23, and the other end located on the outer side of the spiral spring connected to the assembly 292. The inner side of the spiral spring refers to the side of the spiral spring closest to the inner nest 23, and the outer side of the spiral spring refers to the side of the spiral spring closest to the assembly 292.
[0060] In one embodiment, see Figure 1 and Figure 2 The secondary umbrella rib 27 is also provided with a second limiting member 2714. The second limiting member 2714 is located between the upper nest 22 and the secondary connecting member 271. In this way, by providing the second limiting member 2714 on the secondary umbrella rib 27, the second limiting member 2714 can limit the distance that the secondary connecting member 271 can move towards the upper nest 22 during the umbrella closing process.
[0061] Further, see Figure 1 and Figure 2 The inner canopy 23 and the lower canopy 24 move along the axial direction of the center rod 21 towards the upper canopy 22, so that the main rib 25 and the auxiliary rib 27 are in the open state. In the open state, the auxiliary connector 271 abuts against the second limiting member 2714. When opening the canopy, the lower canopy 24 is pushed along the axial direction of the center rod 21 towards the upper canopy 22 until the auxiliary connector 271 abuts against the second limiting member 2714, thus completing the opening of the canopy.
[0062] In one embodiment, see Figure 1 There are multiple main umbrella ribs 25 and secondary umbrella ribs 27, and all main umbrella ribs 25 and all secondary umbrella ribs 27 are arranged alternately along the circumference of the upper nest 22. Because the main umbrella ribs 25 and secondary umbrella ribs 27 are arranged alternately along the circumference of the upper nest 22, the umbrella fabric can be rolled up more effectively.
[0063] It should be noted that the number of main umbrella ribs 25 and secondary umbrella ribs 27 can be set according to actual needs, and no specific limit is made here.
[0064] In this embodiment, see Figure 1 There are eight main umbrella ribs 25 and eight secondary umbrella ribs 27, which are arranged alternately along the circumference of the upper nest 22.
[0065] In one embodiment, see Figure 1 The umbrella rib structure 20 also includes a handle 242, which is fitted onto and connected to the lower nest 24. Optionally, the handle 242 is connected to the lower nest 24 by a snap-fit mechanism. In this way, by providing the handle 242, the handle 242 can protect the lower nest 24, prevent damage to the lower nest 24, and extend its service life.
