Description

Technical Field

[0001] The utility model relates to the field of umbrella ribs, in particular to an extended double-support umbrella rib. Background Art

[0002] Umbrella ribs are a key part of the structure of an umbrella. They are the frame components that support the umbrella canopy and maintain its shape. The main function of the umbrella ribs is to support the umbrella canopy and keep it open to provide protection from rain or sun. Umbrella ribs are usually composed of multiple slender rods or strips that radiate outward from the center point of the umbrella (the top or axis of the umbrella) to form one or more circular or oval frames. Ribs can be made of a variety of materials, including but not limited to metal (such as steel, aluminum), plastic, carbon fiber, bamboo, etc. Different materials will affect the weight, strength and durability of the umbrella ribs;

[0003] Conventional umbrella ribs in the prior art are all single-frame, with simple design and low cost, but they have problems of poor stability and reduced durability, and are prone to flipping or bending in strong winds. Utility Model Content

[0007] The fan-shaped expansion angle of the extended support portion is 5° to 45°, and the small-diameter end is arranged toward the second support rod;

[0008] The two support rods are connected by an adjusting sliding block sleeve, and the adjusting sliding block is connected to the side of the support rod one by a rubber connecting strip. When the angle between the support rod one and the support rod two gradually increases, the adjusting sliding block slides outside the support rod two in a direction away from the extended support portion and separates the two support rods two at the same time.

[0009] A preferred technical solution, the extended support part includes support rods three respectively arranged at the ends of two support rods two, each support rod two is rotatably connected with the support rod three through a connecting piece two, and the support rod one is connected to the lower end of the support rod three through two pull ropes two, and the pull ropes two are connected to the upper half side surface close to the support rod one. When the support rod one swings, the pull ropes two pull the lower end of the support rod three, and let the support rod three swing outward with the connection section with the connecting piece two as the guide, and during the swinging process, the two support rods three gradually spread outward in a fan shape.

[0010] A preferred technical solution is that the adjusting sliding block includes two symmetrically arranged hollow tube monomers, which are respectively sleeved outside the two support rods, and a through hole is provided in the hollow tube monomer, and there is a movable space between the surface of the through hole and the support rod for the support rod to bend.

[0011] A preferred technical solution is that the hollow tube monomer is provided with unequal diameter holes, the middle part of the unequal diameter holes is arranged in an inclined shape, and the spacing between the first and last ends of the unequal diameter holes and the support rod two is unequal, and the end with a larger spacing is arranged toward the support rod three.

[0012] A preferred technical solution is that the two support rods 2 are connected to the support rod 3 through the connecting piece 2 set at the end, the magnets 1 in the two support rods 2 magnetically repel each other, and the support rod 3 connected to each connecting piece 2 is provided with a magnet 2 corresponding to the magnet 1 in the connecting piece 2 connected to it, and the magnets 1 in the connected connecting piece 2 and support rod 3 are magnetically attracted to the magnet 2.

[0015] Compared with the prior art, this technical solution has the following advantages:

[0016] In the utility model, when the umbrella needs to be unfolded, the extended support part of the rib monomer gradually unfolds from the initial closed state, that is, the fan-shaped unfolding angle of the extended support part is about 5°. As the fan-shaped angle of the extended support part gradually increases by 5° to 45°, the rib monomer unfolds from the main handle to the top until it reaches the maximum unfolding angle of 45°. At this time, the rib is fully opened to form a stable support structure. The fan-shaped design of the extended support part ensures that the umbrella cloth can be evenly supported when unfolded. This design avoids the eversion phenomenon caused by uneven force when the umbrella cloth is affected by wind. As the extended support part is unfolded, the rib monomer forms a stable support network, which greatly enhances the stability of the umbrella in wind and rain. The structural design and material selection of the extended support part enable the rib monomer to effectively disperse and resist these forces when it is affected by external forces such as strong winds, thereby preventing the rib monomer from bending or breaking.

[0031] An extended double-support umbrella rib, comprising a main handle 1 and umbrella rib monomers 2 installed on the main handle 1, the umbrella rib monomers 2 are arranged in a rotating array, each umbrella rib monomer 2 comprises a support rod 1 21, a support rod 22 and an extended support part, the number of the support rod 22 is two, the two support rods 22 are movably connected to the support rod 1 21 through the same connecting piece 1 221, and the extended support part is arranged on the side of the two support rods 22 away from the connecting piece 1 221, and the extended support part is arranged in a fan-shaped expansion shape, during the manufacturing process, all umbrella rib monomers 2 are swing-mounted outside the main handle 1, and umbrella cloth 3 is sewn to the outside of all umbrella rib monomers 2, when all umbrella rib monomers 2 are unfolded, the umbrella cloth 3 is supported, and the stress condition of the umbrella cloth 3 is evenly supported by the extended support part, and when subjected to strong winds, the umbrella cloth 3 is prevented from turning outward or the umbrella rib monomer 2 is bent and broken due to uneven stress.

[0032] The fan-shaped expansion angle of the extended support portion is 5° to 45°, and the small-diameter end is arranged toward the support rod 22. When the expansion angle of the extended support portion is 5°, the ribs are closed, and when the angle is 45°, the ribs are fully expanded. It is easy to infer that the ribs are gradually opened between 5° and 45°.

[0033] The working principle of the extended double-support umbrella rib mainly relies on the ingenious design and flexible movable connection of the umbrella rib monomer 2. Each umbrella rib monomer 2 is composed of a support rod 1 21, two support rods 22 and an extended support portion. The two support rods 22 are movably connected to the support rod 1 21 through a connecting piece 1 221, allowing the umbrella rib monomer 2 to change its angle accordingly when folding and unfolding.

[0034] When the umbrella needs to be unfolded, the extended support portion of the rib monomer 2 gradually unfolds from the initial closed state, i.e., the fan-shaped extended angle of the extended support portion is about 5°. As the fan-shaped angle of the extended support portion gradually increases from 5° to 45°, the rib monomer 2 unfolds upward from the main handle 1 until it reaches the maximum unfolding angle of 45°, at which point the ribs are fully opened to form a stable support structure;

[0035] The advantages when expanded are as follows:

[0036] Uniform support: The fan-shaped design of the extended support portion ensures that the umbrella cloth 3 can be evenly supported when unfolded. This design avoids the umbrella cloth 3 from everting due to uneven force when it is affected by wind.

[0037] Enhanced stability: As the extended support portion unfolds, the rib monomer 2 forms a stable support network, which greatly enhances the stability of the umbrella in wind and rain.

[0038] Prevent bending and breaking: The structural design and material selection of the extended support portion enable the umbrella rib monomer 2 to effectively disperse and resist external forces such as strong winds, thereby preventing the umbrella rib monomer 2 from bending or breaking.

[0039] The advantages of closing are as follows:

[0040] Easy to carry: When the umbrella is not in use, the rib monomer 2 can be folded by simple operation, so that the fan-shaped angle of the extended support portion is gradually reduced to about 5°, so that the umbrella is in a closed state, which is easy to carry and store.

[0041] Protect the umbrella cloth: In the closed state, the umbrella cloth 3 is tightly wrapped around the outside of the umbrella rib monomer 2, which can effectively prevent the umbrella cloth 3 and the umbrella rib monomer from being damaged or contaminated.

[0042] The two support rods 22 are connected by an adjusting sliding block 25, and the adjusting sliding block 25 is connected to the side of the support rod 1 21 through a rubber connecting strip 252. When the angle between the support rod 1 21 and the support rod 2 22 gradually increases, the adjusting sliding block 25 slides outside the support rod 2 2 in a direction away from the extended support portion and separates the two support rods 2 22 at the same time.

[0043] Further, the extended support portion includes a support rod 3 23 respectively arranged at the ends of two support rods 22, each support rod 22 is rotatably connected to the support rod 3 23 through a connecting piece 222, and the support rod 1 21 is respectively connected to the lower end of the support rod 3 23 through two pull ropes 214, and the pull ropes 214 are connected to the upper half side surface close to the support rod 1 21. When the support rod 1 21 swings, the pull ropes 214 pull the lower end of the support rod 3 23, and let the support rod 3 23 swing outward with the connection section with the connecting piece 222 as the reference point, and during the swinging process, the two support rods 3 23 gradually spread outward in a fan shape;

[0044] The design of the expandable double-support umbrella ribs realizes the expansion and closing of the umbrella ribs through a unique sliding and rope pulling mechanism. Specifically, when the umbrella ribs need to be expanded, the angle of the first support rod 21 relative to the second support rod 22 is gradually expanded. During this process, the adjustment sliding block 25 slides on the second support rod 22 and moves away from the expansion support portion, thereby causing the two second support rods 22 to separate.

[0045] At the same time, the two pull ropes 214 on the support rod 1 21 begin to work. Since the pull ropes 214 are connected to the upper side surface of the support rod 1 21 and the lower end of the support rod 3 23, as the support rod 1 21 swings, the pull ropes 214 will pull the lower end of the support rod 3 23, so that the support rod 3 23 swings outward with the connecting piece 2 222 as the fulcrum. The synchronous swinging of the two support rods 3 23 will gradually form a fan shape, thereby increasing the coverage area of ​​the umbrella.

[0046] In addition, the adjustment sliding block 25 includes two symmetrically arranged hollow tube monomers 251, which are respectively sleeved on the outside of the two support rods 22, and a through hole is provided in the hollow tube monomer 251. There is a movable space between the surface of the through hole and the support rod 22 for the support rod 22 to bend when the support rod 22 is bent, so as to allow the support rod 22 to move smoothly when bending.

[0047] In addition, the hollow tube monomer 251 is provided with an unequal diameter hole 2511, the middle part of the unequal diameter hole 2511 is arranged in an inclined shape, and the spacing between the first and second ends of the unequal diameter hole 2511 and the support rod 22 is unequal, and the end with a larger spacing is arranged toward the support rod 3 23, and the two support rods 22 are connected to the support rod 3 23 through the connecting piece 222 arranged at the end, and the magnets 1 2221 in the two support rods 22 magnetically repel each other, and the support rod 3 23 connected to each connecting piece 222 is provided with a magnet 231 corresponding to the magnet 1 2221 in the connecting piece 222 connected thereto, and the magnets 1 2221 in the connected connecting piece 222 and the support rod 3 23 are magnetically attracted to the magnet 231;

[0048] The above design cleverly combines the sliding mechanism, the pull rope mechanism and the magnetic adsorption principle. When the umbrella ribs need to be unfolded, the angle between the support rod 1 21 and the support rod 22 gradually expands. In this process, the two hollow tube monomers 251 of the adjusting sliding block 25 slide on the support rod 22 and move in the direction away from the extended support portion. Due to the design of the unequal diameter holes 2511, the support rod 22 can pass through the unequal diameter holes 2511 more smoothly when bending, thereby achieving smooth sliding. It can be understood that this process mainly applies pressure to the two support rods 2 by adjusting the sliding block 25 to push them outward.

[0049] At the same time, the two pull ropes 214 on the support rod 1 21 start to work, pulling the lower end of the support rod 3 23, so that the support rod 3 23 swings outward with the connecting piece 222 as the fulcrum; the synchronous swinging of the two support rods 3 23 gradually forms a fan shape, thereby increasing the coverage area of ​​the umbrella;

[0050] During the unfolding process, the two support rods 22 are connected to the support rod 3 23 through the connecting piece 222 arranged at the end; the connecting piece 222 is provided with a magnet 1 2221, and each support rod 3 23 is provided with a magnet 2 231 corresponding to the magnet 1 2221; these magnets play an important role in the unfolding of the umbrella ribs; due to the magnetic repulsion of the magnets 1 2221 in the two support rods 22, an outward pushing force will be generated between them, which is conducive to the separation of the support rods 22 and the unfolding of the umbrella ribs; and the magnetic attraction between the magnet 1 2221 and the magnet 2 231 ensures that the support rod 3 23 can be stably maintained in a specific position after unfolding, thereby enhancing the stability of the umbrella ribs;

[0051] Furthermore, a connecting rod 211 is provided on the side of the support rod 1 21, and the connecting rod 211 is connected to the upper end of the support rod 1 21 through a spring 212, and a connecting rod 1 24 is movably installed at one end of the support rod 22 away from the support rod 3 23, and the connecting rod 211 is connected to the end of the connecting rod 1 24 through a pull rope 1 213, and when the connecting rod 211 is pulled, the support rod 22 is driven to swing through the connecting rod 1 24, and the extended support part is fanned out.

[0052] Furthermore, the linkage rod 1 24 is connected to the pull rope 1 213 and the connecting member 1 221 respectively through a connecting member 3 241;

[0053] In the present invention, it should be stated that the support rods 1, 2, and 3 can be replaced by the same or different rod-shaped objects, or it can be understood that the support rods 1, 2, and 3 do not limit the practicality of a certain rod-shaped object, but only need to meet the requirements of connectivity and corresponding materials when used, and the connectors 1, 2, and 3 can be any equipment and structure that meet the connection requirements as described above;

[0054] Based on the above content, it can be understood that, compared with the prior art, the present invention sets the single rib in the prior art as a double rib, that is, the original six, eight, ten, or twelve ribs can be regarded as twelve, sixteen, twenty, or twenty-four ribs supporting the umbrella cloth at the same time when the technical solution in the present invention is adopted.

[0055] The above are only preferred embodiments of the present invention, and therefore cannot be used to limit the scope of implementation of the present invention. That is, equivalent changes and modifications made according to the patent scope of the present invention and the contents of the specification should still fall within the scope covered by the present invention.
