Description

Technical Field

[0001] This utility model relates to the field of garden umbrella technology, specifically a garden umbrella with an easily replaceable canopy. Background Technology

[0002] A patio umbrella is a type of sun umbrella designed specifically for outdoor use, typically used in gardens, balconies, terraces, or patios. Its main function is to provide shade, allowing people to enjoy a cool environment while outdoors and avoiding the harmful UV rays caused by direct sun exposure. Patio umbrellas come in a variety of designs and sizes, ranging from small single umbrellas to large family umbrellas. The canopy is usually made of weather-resistant polyester fibers or other synthetic materials to ensure durability and water resistance in different climates. Many patio umbrellas also feature adjustable tilt functions, allowing users to adjust the angle according to the sun's position to maximize shade. In addition, the base design of the patio umbrella is also very important, usually requiring a sturdy support to prevent it from tipping over due to wind.

[0003] Patent application CN202323442173.2 discloses a patio umbrella, which "includes an umbrella handle and an umbrella frame mounted on the handle, with an umbrella fabric fixedly connected to the umbrella frame. The feature is that multiple mosquito nets are detachably connected to the edges of the umbrella fabric, and a storage mechanism for storing the mosquito nets is provided on the outer side of the umbrella handle." This invention allows the patio umbrella to not only provide sunshade but also, in summer, allow mosquito nets to be assembled onto the umbrella fabric for mosquito prevention, effectively reducing mosquito bites. Furthermore, the storage mechanism on the umbrella handle allows for proper storage of the mosquito nets after disassembly. The storage effectively avoids the problem of not being able to find the mosquito net after storage. It can be used at any time, which is simple and convenient. The umbrella frame is made of carbon fiber material, which ensures the overall strength of the umbrella frame and makes it have a longer service life. Based on the above patent search and combined with the existing technology of garden umbrellas, it was found that the umbrella cloth of the existing garden umbrella is located at the top of the umbrella body. When replacing the umbrella cloth, it is usually necessary to replace the whole umbrella, which is very time-consuming and laborious. In addition, garden umbrellas are easily damaged in extreme weather such as strong winds and heavy rain. Even if the umbrella cloth is folded up, the folded umbrella cloth still has a large stress surface and is easily blown down by strong winds, or even damaged.

[0004] Based on this, this utility model designs a courtyard umbrella that is easy to replace the umbrella fabric, in order to solve the above problems. Utility Model Content

[0025] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0026] Please see Figures 1-6In this embodiment of the present invention, a garden umbrella with an easily replaceable canopy includes an umbrella frame 1, a supporting frame 2 above the umbrella frame 1, an umbrella canopy 3 on the supporting frame 2, and adjustment mechanisms 4 on both the top and bottom of the umbrella frame 1. A supporting mechanism 5 is located below the adjustment mechanism 4. The adjustment mechanism 4 includes a connecting umbrella rod 401, a first turntable 402, a first rotating rod 403, and a first bearing frame 404. The first bearing frame 404 is fixedly installed at the upper end of the umbrella frame 1, the first rotating rod 403 is installed in the middle of the first bearing frame 404, the first turntable 402 is installed on the first rotating rod 403, and the connecting umbrella rod 401 is fixedly connected to the upper end of the first turntable 402. The structure 4 also includes a first threaded seat 405 and a second threaded seat 406. The first threaded seat 405 is fixedly installed on the outer wall of the umbrella frame 1 near the first bearing frame 404. The second threaded seat 406 is fixedly installed on the outer wall of the connecting umbrella rod 401 near the first turntable 402. The internal thread of the first threaded seat 405 is connected to a connecting screw 407. The connecting screw 407 extends upward to the second threaded seat 406. The lower end of the umbrella frame 1 is fixedly installed with a second turntable 408. The middle part of the second turntable 408 is installed with a second rotating rod 409. The lower part of the second rotating rod 409 is installed with a second support frame 410. The second support frame 410 is fixedly installed on the upper end of the mounting frame 502.

[0027] See Figure 1 , Figure 4 and Figure 5 Initially, when replacing the umbrella fabric 3, the entire patio umbrella can be folded twice to lay it flat. First, tighten the connecting screw 407 so that it is no longer connected to the first threaded seat 405 and the second threaded seat 406. Then, rotate the connecting umbrella rod 401, the upper support frame 2, and the umbrella fabric 3 to the right so that the umbrella fabric 3 is positioned on the umbrella frame 1. At this point, the umbrella fabric 3 can be replaced. However, for easier replacement, the limiting rod 506 can be removed so that it no longer restricts the umbrella frame 1. Rotate the umbrella frame 1 to the left and lay it down on the ground. The umbrella fabric 3 will then be close to the ground with its front facing up, allowing the user to quickly adjust the umbrella fabric 3. Similarly, in strong winds and heavy rain, the entire patio umbrella can be folded according to the above operation to prevent strong winds from having too much impact on it.

[0028] Among them, the adjustment mechanism 4 adopts a double-end adjustable folding structure, which can quickly lay the entire courtyard umbrella flat on the ground, so that the support frame 2 faces upward, making it convenient for users to repair or replace the umbrella fabric 3. In addition, the adjustability of the adjustment mechanism 4 enables the entire courtyard umbrella to cope with more severe wind and rain weather. By folding the entire courtyard umbrella flat on the ground through the adjustment mechanism 4, the umbrella fabric 3 is no longer located at a high position, and the wind force it receives is greatly reduced, effectively protecting the umbrella fabric 3, and also protecting the entire courtyard umbrella.

[0029] The support mechanism 5 includes a support plate 501 and a mounting frame 502. The mounting frame 502 is provided below the umbrella frame 1. The support plate 501 is fixedly installed at the lower end of the mounting frame 502. The support mechanism 5 also includes a counterweight 503 and a limiting slot 504. The counterweight 503 is fixedly installed on the inner wall of the mounting frame 502. The limiting slot 504 is opened inside the counterweight 503. The right end of the second turntable 408 is fixedly installed with a plug ring 505. The plug ring 505 is provided with a limiting rod 506 inside. The limiting rod 506 and the limiting slot 504 are in a plug-in relationship.

[0030] See Figure 1 , Figure 4 and Figure 5 The support mechanism 5 can be bolted or embedded underground. For bolt installation, select a cement surface and use bolts to fix the support plate 501 to the ground. Alternatively, it can be placed in soil. For embedded underground installation, select an installation location, place the support plate 501 and mounting frame 502 underground, and then use concrete or cement to fix the support plate 501 and mounting frame 502 underground. This installation method does not move, but the support effect is excellent and the stability is very high. When folding the umbrella frame 1, the limiting rod 506 needs to be pulled out, the umbrella frame 1 can be rotated to the left and laid down. Conversely, when erecting the umbrella frame 1, the limiting rod 506 needs to be inserted through the insertion ring 505 and inserted into the limiting slot 504 to achieve the effect of stabilizing the umbrella frame 1 and the overall garden umbrella.

[0031] Among them, the support mechanism 5 can be bolted or embedded in the ground and can be installed and adjusted according to actual needs. The support plate 501 and the mounting bracket 502 are made of aluminum steel frame, which can effectively support the whole garden umbrella. In addition, the counterweight block 503, limit slot 504, insertion ring 505 and limit rod 506 inside the support mechanism 5 are used in conjunction with the adjustment mechanism 4. The limit rod 506 plays an important role when folding or standing up the garden umbrella.

[0032] The working principle of this utility model is as follows: Firstly, it relies on the unique design of its adjustment mechanism 4 and support mechanism 5. The adjustment mechanism 4 adopts a double-end adjustable folding structure, allowing users to quickly lay the upright patio umbrella flat on the ground. During this process, the umbrella fabric 3 will change position due to the folding of the umbrella frame 1, with the support frame 2 facing upwards, forming a state that is easy for users to operate. Users can easily adjust or replace the umbrella fabric 3, greatly improving the convenience of use. In the face of inclement weather conditions, the adjustability of the adjustment mechanism 4 also demonstrates its important value. When strong winds and heavy rain arrive, the user only needs to fold and flatten the entire patio umbrella using the adjustment mechanism 4. The umbrella fabric 3 is no longer suspended in the air, thus reducing the wind force it receives and effectively protecting the umbrella fabric 3 and the entire structure of the patio umbrella, preventing damage caused by strong winds. The support mechanism 5 provides stable support for the entire umbrella frame 1. The support plate 501 and the mounting bracket 502 together constitute the basic structure of the support mechanism 5. The mounting bracket 502 is fixed to the bottom of the umbrella frame 1. The design of the counterweight 503 and the limiting slot 504 enhances the overall stability. The built-in limiting slot 504 of the weight 503 is connected to the insertion ring 505 and limiting rod 506 of the second turntable 408, so that the umbrella frame 1 can be effectively locked when standing up and lying down. When operating, if the user chooses bolt installation, the support plate 501 needs to be fixed with bolts on the cement ground. If the user chooses underground embedded installation, the support plate 501 and the mounting bracket 502 need to be buried in the ground at the selected location and fixed with concrete. Both installation methods have their advantages and disadvantages, but both can provide excellent support and stability. When operating the folding umbrella frame 1, the user only needs to pull out The limiting rod 506 allows the umbrella frame 1 to be rotated to the left and laid down. When re-erecting the umbrella frame 1, the limiting rod 506 must be inserted into the insert ring 505 and aligned with the limiting slot 504 to achieve a stable erection, ensuring the safety and stability of the umbrella frame 1 under various environmental conditions. In summary, this garden umbrella, through the ingenious combination of the adjusting mechanism 4 and the supporting mechanism 5, achieves the purpose of easy replacement of the umbrella fabric. At the same time, while ensuring the stability of the umbrella frame 1, it improves the safety and convenience of use, adapts to various weather conditions, and provides users with a better outdoor experience.
