Description

Technical Field

[0001] This utility model belongs to the field of parasol technology, and specifically refers to a telescopic structure for the ribs of a parasol. Background Technology

[0002] Sun umbrellas, as common outdoor sunshade devices, are widely used in courtyards, beaches, terraces, and other places to provide people with comfortable shade. The rib structure of sun umbrellas is mostly of a fixed length, requiring users to unfold and fold the umbrella fabric for use and storage. This traditional structure results in a fixed shading area, unable to be adjusted according to actual usage conditions. Furthermore, an excessively large umbrella surface not only takes up space but may also affect overall stability due to excessive wind resistance. While existing methods allow changing the shading area by replacing different sized umbrella fabrics, this is overly cumbersome and impractical. In addition, the fixed-length ribs also lead to significant transportation costs for storage and transport. Utility Model Content

[0003] The purpose of this invention is to provide a telescopic structure for the ribs of a parasol, which can flexibly adjust the shading area, achieve efficient storage, and reduce transportation costs.

[0004] The purpose of this utility model is achieved as follows: A telescopic umbrella rib structure includes an umbrella pole, a sliding lower umbrella plate and a fixedly connected upper umbrella plate on the umbrella pole, wherein the upper umbrella plate and the lower umbrella plate are respectively hinged to a plurality of circumferentially distributed long umbrella ribs and short umbrella ribs, the outer end of the short umbrella ribs is hinged to the middle part of the long umbrella ribs, and the long umbrella ribs include an inner tube and an outer tube that are nested together and can slide relative to each other, and the inner tube or the outer tube is provided with a locking mechanism for locking it to the other at different telescopic positions.

[0005] The present invention is further configured such that the umbrella pole is composed of at least two pole bodies connected together.

[0006] The present invention is further configured such that the number of poles is three sets, namely an upper umbrella pole, a middle umbrella pole and a lower umbrella pole. A connecting tube is provided between the upper umbrella pole and the middle umbrella pole, and the upper and lower ends of the connecting tube are respectively formed with insertion ends for inserting into the bottom of the upper umbrella pole and the top of the middle umbrella pole.

Detailed Implementation

[0019] The present invention will be further described below with reference to the accompanying drawings and specific embodiments. See also: Figure 1 — Figure 8 : A telescopic umbrella rib structure includes an umbrella pole 1, a lower umbrella plate 2 that slides on the umbrella pole 1 and an upper umbrella plate 3 that is fixedly connected to it. The upper umbrella plate 2 and the lower umbrella plate 3 are respectively hinged to a plurality of circumferentially distributed long umbrella ribs 4 and short umbrella ribs 5. The outer end of the short umbrella rib 5 is hinged to the middle part of the long umbrella rib 4. The long umbrella rib 4 includes an inner tube 40 and an outer tube 41 that are nested together and can slide relative to each other. The inner tube 40 or the outer tube 41 is provided with a locking mechanism 6 for locking it to the other in the telescopic position.

[0020] like Figures 1-4 As shown, during installation and use, the user adjusts the extension and retraction of the outer tube in the long umbrella rib 4 according to the required shading area, and locks it through the locking mechanism 6.

[0021] The size of the umbrella canopy is based on the maximum distance the inner tube 40 extends relative to the outer tube 41. When the inner tube 40 is shortened, i.e., when the inner tube 40 extends into the outer tube 41, the original edge of the umbrella canopy will droop due to the lack of support, which allows for easy adjustment of the shading area. Furthermore, no replacement of the umbrella ribs or canopy is required during adjustment, making it convenient for users. Shortening the size of the umbrella ribs during transportation significantly reduces the space required for transport.

[0022] In addition, the inner tube at the end of the long umbrella rib can be replaced if it is damaged by bumps or bending, so as to facilitate the continued use of the whole.

[0023] Preferably, the umbrella pole 1 is composed of at least two poles connected together. The umbrella pole 1, consisting of several poles, can be disassembled for storage, further reducing transport space.

[0024] Preferably, the number of the poles is three sets, namely an upper umbrella pole 10, a middle umbrella pole 11, and a lower umbrella pole 12. A connecting pipe 13 is provided between the upper umbrella pole 10 and the middle umbrella pole 11, and the upper and lower ends of the connecting pipe 13 are respectively formed with insertion ends for inserting into the bottom of the upper umbrella pole 10 and the top of the middle umbrella pole 11. The bottom of the middle umbrella pole 11 is inserted into the top of the lower umbrella pole 12 and locked by bolts.

[0025] like Figure 8 As shown, in the above structure, the umbrella pole adopts a three-section structure, which is connected and locked by connecting pipes with plug-in ends and bolts. Adjacent upper and middle umbrella poles can be easily connected by simple connecting pipes 13, which provides certain convenience for installation. Furthermore, the middle and lower umbrella poles are further tightened by bolts, as they will support the base, so this part is reinforced.

[0026] In addition, in actual use, the upper umbrella pole 10 and the middle umbrella pole 11 are often glued at the upper and lower insertion ends of the connecting tube 13 to realize the structure of the upper umbrella pole 10 and the middle umbrella pole 11 as one unit. The lower umbrella pole 12 is further disassembled into two pole structures so that the bottom can be used as a disassembly part to avoid affecting the sliding of the upper lower umbrella plate 3, and at the same time, it can also facilitate the transportation operation after the bottom is disassembled.

[0027] Preferably, an outer tube terminal 410 is fixed to the end of the outer tube 41, and an outer tube end hole 411 for the inner tube 40 to pass through is provided on the outer tube terminal 410. An inner tube terminal 400 is fixed to the outer end of the inner tube 40. When the inner tube 40 extends into the outer tube 41 through the outer tube end hole 411 to the maximum extent, the inner end face of the inner tube terminal 400 abuts against the outer end face of the outer tube terminal 410.

[0028] In the above structure, the outer tube terminal 410 can prevent the inner tube 40 from falling completely into the outer tube 41 when the inner tube terminal 400 is retracted, thus serving as a limiting function. Furthermore, when pulling out the inner tube 40, the user can pull out the inner tube by pinching the inner tube terminal 400, making the operation simpler.

[0029] Preferably, the outer tube 41 and the inner tube 40 are provided with limiting side holes 412 at their outer ends, and the inner sidewalls of the outer tube terminal 410 and the inner tube terminal 400 are provided with limiting hemispheres 413 that can be inserted into the limiting side holes 412.

[0030] Furthermore, both types of terminals are installed using a socketing method. During the socketing process, the spherical surface of the limiting hemisphere 413 abuts into the limiting side hole 412 to achieve socketing and fixation.

[0031] Preferably, the locking mechanism 6 includes a U-shaped spring piece 60 with both ends abutting against the inner sidewall of the inner end of the inner tube 40. The end of the spring piece 60 is fixed with a limiting post 61 with a spherical end. The sidewall of the inner end of the inner tube 40 is provided with a limiting hole 401 for the limiting post 61 to be pushed out. The sidewall of the outer end of the outer tube 41 is provided with a snap-fit ​​hole 414. When the inner tube 40 is pulled out to its maximum from the outer end of the outer tube 41, the end of the limiting post 61 is embedded in the snap-fit ​​hole 414.

[0032] In the above structure, the spring 60 drives the limiting post 61 to push out of the limiting hole 401. When the sliding inner tube reaches its maximum, the spherical surface on the limiting post 61 will slide into the snap-fit ​​hole 414, thereby preventing the inner tube 40 from slipping out of the outer tube 41 and ensuring actual use.

[0033] Preferably, the upper end of the long umbrella rib 4 is fixed with an umbrella surface 7, and the umbrella surface 7 is made of elastic fabric.

[0034] like Figure 5 and Figure 6As shown, in the above structure, the elastic fabric can perfectly adapt to the changes in the length of the umbrella ribs, keeping the umbrella surface taut and flat, without producing too many wrinkles or excessive tightness, ensuring aesthetics and optimal sunshade effect.

[0035] Preferably, a pull rope is threaded through the umbrella pole 1, a fixed pulley 20 for embedding the pull rope is provided at the top of the umbrella pole 1, a handwheel 14 connected to the end of the pull rope is provided on the umbrella pole 1, and the other end of the pull rope is fixed to the upper end of the lower umbrella disc 3.

[0036] The umbrella pole is equipped with a pull rope controlled by a first pulley and a fixed pulley, which makes it easy to lift the lower umbrella disc and facilitates operation.

[0037] In addition, in the above structure, the handwheel can also be used to control the direction of the umbrella pole. In this form, the lower umbrella plate is remotely controlled by a circuit control unit set in the upper umbrella plate to achieve wireless operation. The upper umbrella plate can also provide a light control part for controlling the sun umbrella. The specific details of intelligent operation are not elaborated here.

[0038] The above embodiments are merely preferred embodiments of the present utility model and are not intended to limit the scope of protection of the present utility model. Therefore, all equivalent changes made to the structure, shape, and principle of the present utility model should be covered within the scope of protection of the present utility model.
