DETAILED DESCRIPTION

[0034] In the description of the present invention, it should be understood that the terms "one end", "the other end", "outside", "upper", "inside", "horizontal", "coaxial", "center", "end", "length", "outer end" and the like indicate orientations or positional relationships based on the orientations or positional relationships shown in the accompanying drawings. They are only for the convenience of describing the present invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation. Therefore, they should not be understood as limiting the present invention.

[0035] The present invention will be further described below with reference to the accompanying drawings.

[0036] Please refer to Figures 1 to 11, an adjustable curved arm hanging umbrella includes a base 2, an umbrella column 3 set on the base 2, a curved arm joint 4 rotatably connected to the umbrella column 3, a curved arm assembly 1 slidably connected to the curved arm joint 4, an armrest seat 6 set on the umbrella column 3, an umbrella cover assembly 5 set at the front end of the curved arm assembly 1, a rocking mechanism 9 and a connecting rod 7 set at the rear end of the curved arm assembly, one end of the connecting rod 7 is rotatably connected to the rocking mechanism 9, and the other end is connected to the armrest seat 6 through an adjustment assembly 8. The adjustment assembly 8 includes an armrest joint 800, a telescopic shaft 801 and an elastic reset member 802. The telescopic shaft 801 is slidably connected to the armrest seat 6, and is limited in the circumferential direction with the armrest seat 6 and cannot rotate relative to the armrest seat 6. One end of the armrest joint 800 is fixedly connected to the connecting rod 7, and the other end is sleeved on the telescopic shaft 801, and the armrest joint 800 is locked with the telescopic shaft 801, so that the armrest joint 800 cannot rotate relative to the telescopic shaft 801. The elastic reset member 802 acts on the telescopic shaft 801 to keep the telescopic shaft 801 in a locked state.

[0037] The telescopic shaft 801 in the present invention can slide under the drive of external force to release the locking fit with the armrest joint 800. When the telescopic shaft 801 is in the unlocked state, the armrest joint 800 can rotate relative to the telescopic shaft 801, and the position of the bending arm assembly 1 on the bending arm joint 4 can be adjusted.

[0038] It can be understood that in the above technical solution, the present invention realizes the locking and unlocking of the rotation action of the connecting rod 7 through the adjustment component 8. In the locked state, the stability of the present invention can be maintained. In the unlocked state, the connecting rod 7 can be rotated to adjust the position of the bending arm component 1 on the bending arm joint 4, making the use of the present invention more flexible.

[0039] Continuing with Figures 2-5 , in one embodiment of the present invention, a handrail joint 800 includes a joint collar 8000 that is sleeved onto a telescopic shaft 801. A first locking portion 8001 is provided on one end surface of the joint collar 8000, and a second locking portion 8010 is provided on the telescopic shaft 801 to lockably engage with the first locking portion 8001. The second locking portion 8010 is a tooth structure of a loop, and the first locking portion 8001 is a tooth-groove structure of a loop, with the two locking portions engaging each other.

[0040] In other embodiments of the present invention, the first locking portion 8001 and the second locking portion 8010 may also adopt other structural forms to achieve locking cooperation, such as cooperation between a pin and a socket.

[0041] Further referring to Figures 2 to 5, the armrest seat 6 has a hinge seat 600, and the hinge seat 600 has a mounting hole for slidingly mounting the telescopic shaft 801. The adjustment assembly 8 also includes an armrest cover 803 and an end cover 804 arranged on the mounting holes on both sides of the hinge seat 600. The armrest cover 803 is fixedly connected to the telescopic shaft 801 and can be regarded as a part of the telescopic shaft 801. It is exposed to the armrest seat 6 and can be operated by people. The end cover 804 is fixed to the hinge seat 600.

[0042] The end of the telescopic shaft 801 facing away from the armrest cover 803 has a shaped section 8011. The cross-sectional profile of this shaped section 8011 can be designed to be rectangular, triangular, or hexagonal, etc., and the mounting hole on the hinge base 600 matches this shape and size. The two are circumferentially limited to prevent the telescopic shaft 801 from rotating. The mounting hole on the other end of the hinge base 600 is a circular hole that matches the main body of the telescopic shaft 801. The second locking portion 8010 on the telescopic shaft 801 protrudes radially outward to prevent the telescopic shaft 801 from falling out of the circular mounting hole.

[0043] 3 , in one embodiment of the present invention, the elastic return member 802 is a spring, which is disposed in the hinge seat 600 and connected between the inner wall of the hinge seat 600 and the armrest cover 803 .

[0044] The elastic return member 802 presses the armrest cover 803 away from the telescopic shaft 801, causing the second locking portion 8010 of the telescopic shaft 801 to engage with the first locking portion 8001 of the armrest joint 800, thereby locking the armrest. When the user presses the armrest cover 803, the armrest cover 803 drives the telescopic shaft 801 toward the telescopic shaft 801, overcoming the elastic force of the elastic return member 802. This causes the second locking portion 8010 to separate from the first locking portion 8001, thereby unlocking the armrest.

[0045] In another embodiment of the present invention, the elastic reset member 801 may also be an elastic member such as a V-shaped spring or a torsion spring.

[0046] The position adjustment operation of the bending arm assembly 1 in the present invention includes:

[0047] Under normal circumstances, the telescopic shaft 801 is locked with the armrest joint 800 under the action of the elastic return member 802, and the armrest joint 800 cannot rotate. When the user presses the armrest cover 803, the armrest cover 803 drives the telescopic shaft 801 to move inward, overcoming the elastic force of the elastic return member 802, causing the second locking portion 8010 to separate from the first locking portion 8001, thus unlocking the armrest joint 800 and allowing it to rotate. The position of the curved arm assembly 1 on the curved arm joint 4 is then adjusted. After the adjustment is completed, the user releases the elastic return member 8012, and the telescopic shaft 801 is reset by the elastic return member 802 and locked again with the armrest joint 800.

[0048] The bending arm assembly 1 of the present invention has the following two embodiments:

[0049] Example 1

The end of the first bending arm unit 100 is inserted into the end of the second bending arm unit 101. The splicing assembly includes a first splicing sleeve 102 and a second splicing sleeve 103. The first splicing sleeve 102 is fixedly mounted on the end of the first bending arm unit 100, and the second splicing sleeve 103 is fixedly mounted on the end of the second bending arm unit 101. The second splicing sleeve 103 is used to be threadedly mounted on the first splicing sleeve 102 to realize the splicing of the first bending arm unit 100 and the second bending arm unit 101.

[0051] The first splicing sleeve 102 has an external threaded portion 1023, and the second splicing sleeve 103 has an internal threaded portion 1034 for threaded engagement with the external threaded portion 1023. Several wedge-shaped compression blocks 1024 are arranged around the external threaded portion 1023 toward one end of the second curved arm unit 101, with gaps formed between adjacent compression blocks 1024. The inner wall of the second splicing sleeve 103 has a tapered section 1033 corresponding to the compression blocks 1024. This tapered section 1033 is located at the end of the internal threaded portion 1034 facing away from the first curved arm unit 100, and the compression blocks 1024 and the tapered section 1033 of the second splicing sleeve 103 are tightly engaged.

[0052] It can be understood that in the above technical solution, this embodiment designs the bending arm assembly 1 as a split structure including a first bending arm unit 100 and a second bending arm unit 101, and the first bending arm unit 100 and the second bending arm unit 101 are spliced ​​together by a splicing assembly, so that the length of the bending arm can be reduced during packaging and transportation, thereby improving the convenience of packaging and transportation, and facilitating the sales of the bending arm parasol.

[0053] Continuing to refer to Figure 6, one end of the first curved arm unit 100 has an insertion portion 1000, the outer diameter of the insertion portion 1000 is smaller than the outer diameter of the main body of the first curved arm unit 100, the main body of the first curved arm unit 100 has the same outer diameter as the second curved arm unit 101, the insertion portion 1000 is inserted into the end of the second curved arm unit 101, and the first splicing sleeve 102 is located at the end of the insertion portion 1000 facing away from the second curved arm unit 101.

[0054] Specifically, a transition necking portion 1001 is formed between the main body of the first bending arm unit 100 and the insertion portion 1000 , and an inner stop 1020 is provided on the inner wall of the first splicing sleeve 102 , and the inner stop 1020 is clamped between the transition necking portion 1001 and the end of the second bending arm unit 101 .

[0055] It can be understood that since one end of the curved arm is used to hang the umbrella stand, the insertion portion 1000 will inevitably abut against the inner wall of the second curved arm unit 101, which can enhance the connection stability between the first curved arm unit 100 and the second curved arm unit 101.

[0056] Further referring to FIG. 7 , an anti-slip portion 1031 is provided on the outer wall of the second splicing sleeve 103 . The anti-slip portion 1031 adopts a groove structure with uniform annular distribution. The provision of the anti-slip portion 1031 facilitates the user to operate the second splicing sleeve 103 .

[0057] When leaving the factory, the first splicing sleeve 102 is pre-fixed and installed on the first bending arm unit 100, and the second splicing sleeve 103 is pre-fixed and installed on the second bending arm unit 101. During packaging and transportation, the first bending arm unit 100 and the second bending arm unit 101 are separated, which can reduce the overall length of the bending arm; when arriving at the site, the user assembles the bending arm. During assembly, the insertion part 1000 of the first bending arm unit 100 is inserted into the second bending arm unit 101, and the second splicing sleeve 103 is then put on the first splicing sleeve 102 to achieve the splicing of the bending arm.

[0058] It should be noted that, in this embodiment, the first arm unit 100 is used to connect to the arm joint 4, and the second arm unit 101 is used to connect to the umbrella cover assembly 5. To further reduce the overall length of the arm assembly 1, the arm assembly 1 can be divided into three or even four sections, which can be spliced ​​together using multiple splicing assemblies.
