Description

Technical Field

[0001] This application generally relates to umbrella table assemblies, and particularly to outdoor umbrella table assemblies. Background Technology

[0002] Outdoor sun umbrellas are designed to block direct sunlight and protect against ultraviolet rays, while also providing rain protection. Therefore, it's generally desirable for outdoor sun umbrellas to have a large open canopy diameter (e.g., over 3 meters). However, due to limitations in current umbrella frame (or rib) design technology, the folded length of outdoor sun umbrellas is typically greater than 1.8 meters. This makes them difficult to fit in a car trunk or a user's backpack, reducing their portability.

[0003] Currently, there are some outdoor sun umbrellas on the market that can be folded and stored in the trunk of a family car or in a user's backpack. However, the diameter of the canopy of such outdoor sun umbrellas is usually small when unfolded (e.g., less than 2.5 meters), which cannot fully meet the needs of multiple people for outdoor sun protection, and their wind resistance is poor.

[0004] In addition, traditional outdoor parasols cannot be used well with outdoor folding tables, which means that the outdoor folding table can only be placed next to the central axis of the umbrella frame, so the unfolded umbrella surface sometimes cannot provide enough shade for the tabletop. Summary of the Invention

[0005] To address the aforementioned issues, this application aims to propose a novel umbrella-table assembly that allows both the umbrella and the table to be easily stored and unfolded, and to be easily joined together.

[0025] In the accompanying drawings of this application, features with the same structure or similar function are indicated by the same reference numerals.

[0026] Figure 1 This is a perspective view, schematically illustrating an umbrella-table assembly according to one embodiment of the present application. The umbrella-table assembly includes an umbrella assembly (or sub-assembly) 100 and a table assembly (or sub-assembly) 200. According to an embodiment of the present application, the table assembly 200 can also switch between its deployed state and its disassembled and stored state. The umbrella assembly 100 and the table assembly 200 are detachably connected.

[0027] The umbrella assembly 100 generally includes an umbrella frame and a canopy 101 arranged on the umbrella frame. The umbrella frame can switch between its deployed state and its retracted state. Figure 2 and 3A As shown, according to one embodiment of this application, the tarpaulin 101 generally includes an upper tarpaulin 101a and a lower tarpaulin 101b.

[0028] The umbrella frame of umbrella assembly 100 generally includes a central tube assembly 110 and a plurality of canopy supports 120 radially distributed around the central tube assembly 110. For example, in the illustrated embodiment, umbrella assembly 100 includes eight canopy supports 120 radially distributed around the central tube assembly 110. Figure 3B The bottom view of the umbrella assembly 100 shown reveals eight tent supports 120 radially distributed around the central tube assembly 110. In the context of this application, a radial distribution of multiple (e.g., eight) tent supports 120 around the central tube assembly 110 means that the tent supports 120 are spaced at uniform circumferential intervals. In the illustrated embodiment, the tent supports 120 are spaced at 45-degree intervals around the central tube assembly 110 (360 degrees / 8 = 45 degrees). Each tent support 120 is operatively connected to the central tube assembly 110, and each tent support 120 is configured in the same manner. Therefore, in the following description, the description of the construction of one tent support 120 and its connection to the central tube assembly 110 also applies to the other tent supports 120.

[0029] The central tube assembly 110 mainly includes a first tube 111, a second tube 112, and an extension tube 113. The first tube 111 is connected to one end of the second tube 112 via a tube connector 130, while the opposite end of the second tube 112 is detachably connected to the extension tube 113. According to an embodiment of this application, when the second tube 112 is connected to the extension tube 113, the two can be coaxial with each other; and the tube connector 130 is configured to allow the first tube 111 and the second tube 112 to remain coaxial or, as needed, to maintain a non-zero included angle between them.

[0030] Figure 4 The diagram schematically illustrates a portion of the first tube 111 and the second tube 112 of the central tube assembly 110, as well as a tarpaulin support 120. The central tube assembly 110 also includes a first fixed hinge support 104 and a sliding sleeve 105 slidable as needed along the first tube 111 and the second tube 112 (when the two tubes are coaxial), on which a second hinge support 106 is disposed. The first fixed hinge support 104 and the second hinge support 106 are respectively configured to hinge to the end of a corresponding rod of each tarpaulin support 120. Therefore, each of the first fixed hinge support 104 and the second hinge support 106 may have a plurality (the same number as the number of tarpaulin supports 120) of hinges for hinged to the end of the rod of the corresponding tarpaulin support 120. For example, the first fixed hinge support 104 may be a component independent of the first tube 111 and is fixed to the end of the first tube 111 (which is axially opposite to the second tube 112) by a suitable fixing method. A locking structure 111a is provided in the first tube 111 (e.g., at the location between the first fixed hinge support 104 and the tube connector 130). Figure 5A The sliding sleeve 105 is provided with features that engage with the locking structure 111a, so that when the sliding sleeve 105 moves to the locking structure 111a, the engagement locks the sliding sleeve 105 along the central tube assembly 110, particularly its first tube 111. This locking can also be manually unlocked if necessary. This locking and unlocking can be achieved using methods common in the field of sun umbrellas or outdoor sunshades, and therefore will not be described further herein.

[0031] like Figure 4As shown, each tarpaulin support 120 includes a first rod 121, a second rod 122, a third rod 123, a fourth rod 124, and a fifth rod 125. In the context of this application, the term "rod" refers to a generally straight rod, which may be solid or hollow. The first rod 121 has a first end 121a and a second end 121b opposite to each other, and a slider 121c is provided on the first rod 121, the slider 121c being located between the first end 121a and the second end 121b. In the context of this application, the slider provided on the rod may be a sliding sleeve or any suitable form of slider, preferably without affecting the function described below. The second rod 122 has a first end 122a and a second end 122b opposite to each other, and a first slider 122c and a second slider 122d are provided on the second rod 122, located between the first end 122a and the second end 122b, wherein the first slider 122c is closer to the first end 122a, and the second slider 122d is closer to the second end 122b. The third rod 123 includes a first end 123a and a second end 123b that are opposite to each other. The fourth rod 124 has a first end 124a and a second end 124b that are opposite to each other, and a slider 124c is provided on the fourth rod 124, the slider 124c being located between the first end 124a and the second end 124b. The fifth rod 125 has a first end 125a and a second end 125b that are opposite to each other, and a slider 125c is also provided on the fifth rod 125, the slider 125c being located between the first end 125a and the second end 125b. As shown in the figure, among these rods 121, 122, 123, 124, and 125, the third rod 123 is the shortest rod.

[0032] According to an embodiment of this application, the first end 121a of the first rod 121 and the first end 125a of the fifth rod 125 are simultaneously hinged to the first hinge support 104, with the first rod 121 and the fifth rod 125 radially closer to the central tube assembly 110. The first end 122a of the second rod 122 is hinged to the second hinge support 106, and the second end 122b of the second rod 122 is hinged to the slider 125c on the fifth rod 125. The slider 121c on the first rod 121 is hinged to the first slider 122c on the second rod 122, and the second slider 122d on the second rod 122 is hinged to the first end 124a of the fourth rod 124. The first end 123a of the third rod 123 is hinged to the second end 121b of the first rod 121, and the second end 123b of the third rod 123 is hinged to the slider 124c on the fourth rod 124. In the illustrated embodiment, the second end 125b of the fifth rod 125 and the second end 124b of the fourth rod 124 are free. For example, the upper tarpaulin 101a of the tarpaulin 101 can be detachably connected between the first end 125a and the second end 125b of the fifth rod 125 of each tarpaulin support 120 in a manner known in the art, while the lower tarpaulin 101b of the tarpaulin 101 can be detachably connected between the first end 124a and the second end 124b of the fourth rod 124 of each tarpaulin support 120 in a manner known in the art. When the umbrella assembly 100 is in the deployed state (e.g. Figure 1 As shown, a gap exists between the upper tarpaulin 101a and the lower tarpaulin 101b along the axial direction of the central tube assembly 110. Viewed in a top view, the inner peripheral edge of the lower tarpaulin 101b is radially located within the outer peripheral edge of the upper tarpaulin 101a.

[0033] Figures 5A to 5C The illustration schematically demonstrates how to switch the umbrella frame of umbrella assembly 100 from an unfolded state to a retracted state. Those skilled in the art will understand that because the canopy 101 is made of a flexible material, it can naturally fold accordingly when the canopy supports 120 are switched from the unfolded state to the retracted state. Of course, the canopy 101 can also be unloaded from each canopy support 120 before the umbrella frame is switched from the unfolded state to the retracted state.

[0034] First, loosen the sliding sleeve 105 from the locking structure 111a on the first tube 111. Then, move it along the direction toward the second tube 112 and past the tube connector 130, moving as far away as possible from the first hinged support 104. Figure 5AAs shown, the sliding sleeve 105 is moved onto the second tube 112. During this process, as indicated by the small arrows, the slider 125c on the fifth rod 125 moves toward the first end 125a, and the first slider 122c and the second slider 122d on the second rod 122 move toward the first end 122a, while the slider 124c on the fourth rod 124 moves toward the first end 124a. According to an embodiment of this application, during the unfolding or folding of the umbrella frame, the hinge points between the sliders 122c, 122d, 124c and the second end 121b of the first rod 121 and the second end 123b of the third rod 123 always remain at the four corners of a parallelogram.

[0035] contrast Figure 4 as well as Figures 5A to 5C It can be observed that when the umbrella frame is in the deployed state ( Figure 4 The fourth rod 124 extends radially outward from near the second end 125b of the fifth rod 125, while the umbrella frame is in the retracted state ( Figure 5B The fourth rod 124 largely overlaps with the fifth rod 125. This demonstrates that when the umbrella frame of this application is in the unfolded state, the canopy 101 can cover a larger area, thus providing a larger canopy diameter; while when the umbrella frame is in the stowed state, it can be folded in a way that occupies less volume space.

[0036] like Figure 5C As shown, when the umbrella frame is in the retracted state, the fifth rod 125 of each tarpaulin support 120 is radially outward, and the first rod 121, the second rod 122, the third rod 123, the fourth rod 124 and the fifth rod 125 are radially close to each other.

[0037] Figure 7 The illustration shows a side view of an umbrella assembly 100 according to an embodiment of this application, wherein the first tube 111 of the central tube assembly has a non-zero angle relative to the second tube 112, which is achieved by the tube connector 130 between the first tube 111 and the second tube 112. The advantage of the first tube 111 having a non-zero angle relative to the second tube 112 is that, when the umbrella assembly 100 is normally upright, the angle of the canopy 101 can be adjusted according to the direction of sunlight or wind to provide better sunshade or wind resistance.

[0038] Further reference Figure 6The tube connector 130 generally includes a first connector 131 and a second connector 132. The first connector 131 is capable of selectively residing in different pivot positions relative to the second connector 132 about a pivot axis. The first connector 131 includes a first end 1311 and an opposite second end, for example, on which a multi-tooth portion 1313 is integrally formed. For example, the multi-tooth portion 1313 may be part of a gear of a corresponding size. A through hole 1312 is formed at the center of the multi-tooth portion 1313. The central axis of the through hole 1312 is the central axis of the multi-tooth portion 1313 (the corresponding gear). The multi-tooth portion 1313 is flat, while the first end 1311 of the first connector 131 is cylindrical. For example, the first end 1311 can be fixed to the end of a first tube 111. In the illustrated embodiment, the first end 1311 can be shaped, for example, to be inserted into the first tube 111 in an interference fit manner. Of course, those skilled in the art should understand that other suitable mechanical connection methods familiar to them can also be used to connect the first end 1311 to the first tube 111.

[0039] One end of the second connector 132 is shaped like a fork, integrally forming two spaced-apart wings 1321. These two wings 1321 are radially spaced apart, allowing a positioning member 133 to be inserted between them. The positioning member 133 has a flat body with several teeth formed thereon to engage with a multi-toothed portion 1313. The flat body of the positioning member 133 is configured to be inserted unrestricted into the hollow space defined between the two wings 1321. In the positioning member 133, a post 1331 extends from the body on the opposite side of its teeth. An internally threaded hole 1332 is formed in the post 1331. The axial direction of the post 1331 is parallel to the direction in which the positioning member 133 is inserted into the hollow space defined between the two wings 1321. A flat abutment surface 133a is formed on the body of the positioning member 133, and the post 1331 extends axially perpendicularly from the flat abutment surface 133a.

[0040] A through hole is formed in the second connector 132, which has a large-diameter through hole section 1322 and a small-diameter through hole section 1323 extending from the root of the two wings 1321 toward opposite ends of the second connector 132. Figure 8Therefore, a stepped surface is formed between the large-diameter through-hole section 1322 and the small-diameter through-hole section 1323. The post 1331 of the positioning member 133 can be partially inserted into the large-diameter through-hole section 1322 of the second connector 132. A helical spring 134 can be inserted into the through-hole of the second connector 132 and is located in a compressed state between the post 1331 of the positioning member 133 and the stepped surface, for example, between the end face of the post 1331 of the positioning member 133 and the stepped surface. The helical spring 134 applies a force axially to the positioning member 133, causing it to tend to move away from the second tube 112.

[0041] Through holes 1321a are formed in the two wings 1321, which are coaxial with each other. The multi-toothed portion 1313 of the first connector 131 is inserted between the two wings 1321 so that the through holes 1321a and 1312 are aligned, and then a bolt can be inserted into the aligned holes and screwed in accordingly (for example, the through hole 1321a of one wing 1321 is a threaded hole).

[0042] When installing the positioning component 133, first insert the helical spring 134 into the large-diameter through-hole section 1322, then insert the post 1331 of the positioning component 133 into the large-diameter through-hole section 1322. Simultaneously, insert the bolt 135 from the small-diameter through-hole section 1323 into the large-diameter through-hole section 1322 and screw it into the internal threaded hole 1332 of the post 1331. The head size of the bolt 135 is larger than the inner diameter of the small-diameter through-hole section 1323. The bolt 135 is screwed into the internal threaded hole 1332 to prevent the positioning component 133 from accidentally detaching from the second connector 132 under the action of the helical spring 134 (e.g., before the first connector 131 is installed). Subsequently, the multi-toothed portion 1313 of the first connector 131 is inserted between the two wings 1321 so that the through holes 1321a and 1312 are aligned. Bolts can then be inserted into the aligned holes and correspondingly screwed in to define the pivot axis of the first connector 131 relative to the second connector 132. Because the helical spring 134 applies a force to the positioning member 133 that always tends towards the first connector 131, as the first connector 131 pivots relative to the second connector 132, the positioning member 133 can move slightly axially, and the teeth of the positioning member 133 can always engage with the teeth of the multi-toothed portion 1313. The bolt 135 is sized to prevent accidental disengagement from the second connector 132 only during the installation of the positioning member 133, but does not affect the normal operation of the positioning member 133 after it is in place.

[0043] The abutment surface 133a of the positioning member 133 is configured such that, when the positioning member 133 is installed in place, the abutment surface 133a is exposed between the two wings 1321, for example, at least a portion of it can be exposed radially. An external thread 136 is formed on the outer surface of the second connector 132 at the root of the two wings 1321. This external thread 136 extends axially and at least partially overlaps the two wings 1321, and a locking sleeve 137 with internal threads can be screwed onto this external thread 136. The threaded sleeve 137 can be screwed toward the positioning member 133 such that the end face of the threaded sleeve 137 tightly abuts against a portion of the abutment surface 133a, thereby applying a locking force to the positioning member 133. This locking force is greater than the force of the coil spring 134 and securely holds the first connector 131 relative to the second connector 132. When the angle between the two needs to be adjusted, the threaded sleeve 137 can be screwed away from the positioning member 133 so that the end face of the threaded sleeve 137 disengages from the contact abutment surface 133a, thereby allowing the first connector 131 to be pivoted relative to the second connector 132 about the pivot axis relatively easily. When pivoted to the appropriate position, the threaded sleeve 137 can be screwed toward the positioning member 133 again so that the end face of the threaded sleeve 137 tightly abuts against the portion of the contact surface 133a, thereby applying a locking force to the positioning member 133. An external thread 137 is also formed on the outer surface of the second connector 132, for example, at a location axially away from the two wings 1321, for screwing onto a retaining sleeve 139 with an internal thread. This retaining sleeve 139 can be connected to the second tube 112, for example, in the same manner as the first end 1311 is fixed to the same tube 111.

[0044] The end of the extension tube 113 may be equipped with a tightening and locking device 114, which can be tightened and locked after the end of the second tube 112 opposite to the tube connector 130 is inserted into the extension tube 113, thereby axially securing the second tube 112 and the extension tube 113 together. Such a tightening and locking device 114 is any suitable tightening and locking device known in the art. Through holes 113a are formed in the sidewall of the extension tube 113, for example, through holes 113a being a pair of radially symmetrical through holes.

[0045] Figure 10 A perspective view of a table assembly 200 according to one embodiment of this application is schematically shown. The table assembly 200 generally includes a folding table frame 310 and a folding tabletop 400 detachably supported by the folding table frame 310. Figure 10 and 18 As shown, the desktop component 200 is in a deployed state. Combined with... Figure 13 and 15 As shown, the folding table frame 310 generally supports the folding tabletop 400 via two crossbars 320. Figure 10In the case of the table 400, the folding tabletop 400 is in the unfolded state. Therefore, when the table assembly 200 is in the deployed state, the two crossbars 320 are approximately parallel to each other and extend along the length of the folding tabletop 400.

[0046] The folding table frame 310 includes a central telescopic assembly 330. The central telescopic assembly 330 generally includes an outer tube 331 and an inner tube 332 disposed within the outer tube 331 and capable of longitudinal sliding. For example, the outer tube 331 and the inner tube 332 can be made of a suitable lightweight fastening metal such as stainless steel or aluminum alloy, and can be, for example, in the form of thin-walled tubing. Through holes are formed radially symmetrically in the inner walls of the outer tube 331 and the inner tube 332, for example, two rows of through holes spaced apart longitudinally. When the inner tube 332 slides into the outer tube 331 to a suitable position, the two radial through holes of the inner tube 332 can be aligned with the two radial through holes of the outer tube 331, so that a retaining pin 333 can be inserted into the aligned through holes to fix the inner tube 332 longitudinally relative to the outer tube 331. The inner tube 332 extends from the outer tube 331 and has an exposed end 332a. A base 334 is provided at the end of the outer tube 331 that is longitudinally opposite to the end 332a. For example, the base 334 may be a metal plate welded to the corresponding end of the outer tube 331. A plurality of through holes 334a are formed in the base 334. Figure 12 When the table assembly 200 is in the deployed state, the base 334 is able to contact the ground, and the base 334 can be more securely fixed to the ground outdoors by passing ground fixing nails through these through holes 334a.

[0047] The folding table frame 310 also includes multiple floor support assemblies 340, which can be configured identically. For example, Figure 11The figure shows four ground support leg assemblies 340. Each ground support leg assembly 340 includes a first ground support leg 341 and a second ground support leg 342. The first ground support leg 341 has a first end 341a and a second end 341b opposite to each other. The plurality of ground support leg assemblies 340 shown are arranged around a central telescopic assembly 330. For example, in the case of four ground support leg assemblies 340, four hinge seats are provided on the end 332a of the inner tube 332 (which extends from the outer tube 331), which can be located on a hinge support 332b. In this way, the first end 341a of the first ground support leg 341 of each ground support leg assembly 340 can be hinged to the hinge support 332b (the corresponding hinge seat). In addition, as shown, a tube segment 332c extends longitudinally from the end 332a of the inner tube 332. This tube segment 332c is, for example, a circular tube segment, for alignment or insertion into the mating port 410 of the folding table 400, which will be described later. In the context of this application, the term "hinged" is used in the sense of a connection of two components that are connected to each other about a pivot axis, as is known in the art. Such a hinge can be a direct connection of the two components, or it can be that both components have parts for hinged connection, or one component has parts for hinged connection with the other. A foot pad 343 is hinged at the opposite second end 341b of each first ground support leg 341. According to one embodiment of this application, the foot pad 343 can also be configured to rotate about an axis coaxial or parallel to the central axis of the first ground support leg 341. For example, one or more through holes can be formed in the foot pad 343 to facilitate the passage of ground anchors to more securely fix the first ground support leg 341 relative to the ground outdoors. The second ground support leg 342 of each ground support leg assembly 340 has a first end 342a and a second end 342b opposite to each other. The first end 342a of the second ground support leg 342 is hinged to the end of the outer tube 331 of the central telescopic assembly 330 that is longitudinally opposite to the end 332a, for example, hinged to the base 334, and the second end 342b of the second ground support leg 342 is hinged to a position between the first end 341a and the second end 341b of the first ground support leg 341, for example, approximately at the middle position between the first end 341a and the second end 341b of the first ground support leg 341.

[0048] When the ground support leg assembly 340 of the folding table frame 310 is in the unfolded state (e.g.) Figure 10 , 11As shown in Figures 1 and 12), the second end 341b of the first ground support leg 341 of each ground support leg assembly 340 and the corresponding foot pad 343 are located radially furthest from the central telescopic assembly 330. According to an embodiment of this application, when the ground support leg assembly 340 is in the deployed state, its first ground support leg 341 and second ground support leg 342 form a generally triangular configuration relative to the central telescopic assembly 330, thereby improving the support stability relative to the ground.

[0049] As force is applied, the second end 341b of the first ground support leg 341 and the corresponding foot pad 343 of each ground support leg assembly 340 move radially toward the central telescopic assembly 330. Influenced by the forces exerted by the second ground support leg 342 on the outer tube 331 of the central telescopic assembly 330 and by the first ground support leg 341 on the inner tube 332 of the central telescopic assembly 330, the inner tube 332 of the central telescopic assembly 330 extends longitudinally along the outer tube 331, and the ground support leg assembly 340 of the folding table frame 310 is finally in a retracted state, as... Figure 16 As shown. When the ground support leg assembly 340 of the folding table frame 310 is in the retracted state, the second end 341b of the first ground support leg 341 of each ground support leg assembly 340 and the corresponding foot pad 343 are located radially closest to the central telescopic assembly 330.

[0050] like Figure 18 As shown, when the ground support leg assemblies 340 of the folding table frame 310 are in the unfolded state, each foot pad 343 and the base 334 can be roughly in the same horizontal plane. In this way, after the table assembly 200 is properly deployed, it can make contact with the ground at five points to ensure stable support.

[0051] The folding table frame 310 also includes multiple desktop leg assemblies 350, which can be configured identically. The number of desktop leg assemblies 350 is the same as the number of ground leg assemblies 340. That is, each ground leg assembly 340 is equipped with one desktop leg assembly 350. Each desktop leg assembly 350 includes a first desktop leg 351 and a second desktop leg 352.

[0052] According to embodiments of this application, the first ground support leg 341 and the second ground support leg 342 of the ground support leg assembly 340 can be made of metal profiles or other suitable, durable profiles. Such profiles can have a closed cross-section, such as a round or square tube. The first desktop support leg 351 and the second desktop support leg 352 of the desktop support leg assembly 350 can also be made of profiles, but these profiles have an open cross-section, such as a concave cross-section. Thus, the opening of the hollow cross-section of the profile of the second desktop support leg 352 can be larger than the cross-sectional width of the profile of the first ground support leg 341 of the ground support leg assembly 340, and the opening of the hollow cross-section of the profile of the first desktop support leg 351 can be larger than the cross-sectional width of the profile of the second desktop support leg 352, so that the second desktop support leg 352 can at least partially attach to the surface of the first ground support leg 341 of the ground support leg assembly 340, and the first desktop support leg 351 can at least partially attach to the surface of the second desktop support leg 351. In this way, when the first desktop support leg assembly 350 is in the storage state, it can be attached to the corresponding first ground support leg assembly 340 as a whole, thus occupying a small volume of space.

[0053] The first desktop support leg 351 of the first desktop support leg assembly 350 includes a first end 351a and a second end 351b opposite to each other. The first end 351a of the first desktop support leg 351 is hinged near the first end 341a of the corresponding first ground support leg 341, and the second end 351b of the first desktop support leg 351 is free, while a groove 351c is formed in the second end 351b. Figure 13 The slot 351c is used to detachably receive a locking device for locking the crossbar 320 as described below. The second desktop leg 352 of the first desktop leg assembly 350 includes a first end 352a and a second end 352b opposite to each other. According to an embodiment of this application, the first end 352a of the second desktop leg 352 is hinged to the first desktop leg 351, for example, to a position closer to the first end 351a between the first end 351a and the second end 351b of the first desktop leg 351. The second end 352b of the second desktop leg 352 is free, but a hook 352c is formed in the second end 352b. Figure 13 and 18 The hook 352c is designed to hook into the protrusion 344 provided on the first ground support leg 341. Figure 13 and 18 The second desktop leg 352 can support and fix the first desktop leg 351 when the first desktop leg assembly 350 is in the unfolded state. Thus, when all ground leg assemblies and desktop leg assemblies are in the unfolded state and the folding table frame 310 is arranged on the ground (e.g., ...), the second desktop leg 352 can support and fix the first desktop leg 351. Figure 11As shown), the first desktop support leg 351 of each first desktop support leg assembly 350 can be approximately parallel to the ground. When it is necessary to store the desktop support leg assembly 350, the hook 352c of the second end 352b of the second desktop support leg 352 is released from the corresponding protrusion 344, and the second desktop support leg 352 is pivoted about its first end 352a into the first desktop support leg 351, while the first desktop support leg 351 is pivoted about its first end 351a toward the first ground support leg 341, thereby reaching the position shown. Figure 12 and 16 The first desktop support leg assembly 350 shown is in its stowed state.

[0054] When each of the first desktop support leg assemblies 350 and each of the first ground support leg assemblies 340 is in the deployed state, the second end 351b of each first desktop support leg 351 extends radially outward relative to the central telescopic assembly 330, thereby causing the opening of the slot 351c to face radially outward. Figure 13 As shown, two crossbars 320 are disposed on the first desktop support legs 351 of the first desktop support leg assembly 350. For example, one crossbar 320 is disposed on the second end 351b of the two first desktop support legs 351. Specifically, one crossbar 320 is fixed to a slot 351c in the second end 351b of the two first desktop support legs 351 via two locking devices 360. Figure 14 As shown, the locking device 360 ​​includes a sleeve 361 surrounding a crossbar 320. The locking device 360 ​​also includes a retaining knob 363. For example, a bolt is inserted into the sleeve 361 and the crossbar 320 such that a threaded post 362 of the bolt protrudes from the sleeve 361. The retaining knob 363 has a threaded hole to receive the threaded post 362. For example, when the first desktop leg assemblies 350 and the first ground leg assemblies 340 are in the deployed state, the distance between the two locking devices 360 on a crossbar 320 is exactly equal to the distance between the second ends 351b of the two first desktop legs 351, so that the threaded post 362 is inserted into the slot 351c and the retaining knob 363 is simultaneously screwed on. Subsequently, the fixing knob 361 is further tightened so that the second end 351b of the first desktop support leg 351 is clamped between the insert 361 and the fixing knob 361, thereby fixing the crossbar 320 relative to the first desktop support leg 351 of the first desktop support leg assembly 350. After the two crossbars 320 are fixed in place relative to each of the first desktop support leg assemblies 350 in the above manner, the two crossbars 320 are parallel to each other and their longitudinal direction is the length direction of the folding table 400.

[0055] Figure 15 A folding tabletop 400 according to an embodiment of this application is schematically shown in an unfolded state, and... Figure 15The folding tabletop 400, when installed, faces the ground. As shown, two crossbars 320 are detachably attached to the ground-facing side of the folding tabletop 400. The folding tabletop 400 includes multiple first chain plates 401 and multiple second chain plates 402. For example, the width of the first chain plates 401 (along the length of the crossbars 320) can be greater than the width of the second chain plates 402 (along the length of the crossbars 320). These first chain plates 401 and second chain plates 402 can be connected to each other like watch straps, allowing them to unfold into a generally flat structure (e.g., ...). Figure 10 As shown), to form a generally flat surface, and close to each other in a folded state (as shown). Figure 17 As shown in the figure, the longitudinal direction of each first chain plate 401 or second chain plate 402 reflects the width direction of the folding tabletop 400 in its unfolded state. Buckles 411 are provided in the two first chain plates 401 of the folding tabletop 400. For example, two separate buckles 411 are provided in each of the two outermost first chain plates 401 along the length direction of the folding tabletop 400. For example, the distance between the two buckles 411 of the same first chain plate 401 is approximately equal to the distance between the two crossbars 320 fixedly positioned on the first tabletop leg assembly 351. In the illustrated embodiment, for example, each buckle 411 includes a base block 411a and a C-shaped clamp 412 provided on the base block 411a. Each C-shaped clamp 412 is configured to detachably engage with the crossbar 320.

[0056] like Figure 13 As shown, after the two crossbars 320 have been properly attached to each of the first tabletop legs 351 via the locking device 360, the unfolded folding tabletop 400 can be attached to the two crossbars 320 via corresponding latches 411 (e.g., Figure 15 As shown), the final table component 200 is assembled, as follows. Figure 10 As shown.

[0057] A mating port 410 is formed in the first chain plate 401, which is located approximately at the center of the folding tabletop 400. When the unfolded folding tabletop 400 is attached to the two crossbars 320 in place, a section 332c of the inner tube 332 of the central telescopic assembly 330 can be aligned with or inserted into the mating port 410. Thus, the section 332c of the inner tube 332 of the central telescopic assembly 330 can be used to receive other accessories, such as the handle of a parasol. According to an embodiment of this application, the mating port 410 is located at the center of the plane containing the unfolded folding tabletop 400.

[0058] When it is necessary to store the table assembly 200, the unfolded folding tabletop 400 can first be removed from the unfolded folding table frame 310 by pulling out the C-shaped clamp 412 from the crossbar 320. Then, the unfolded folding tabletop 400 can be rolled up as follows: Figure 15 In the folded state shown. Then, by loosening the fixing knob 363 of the locking device 360, the two crossbars 320 can be removed from the first tabletop support leg 351, as shown. Figure 11 As shown. Then, you can first rotate the desktop support leg assembly 350 to its folded-back state, as shown. Figure 12 As shown. Finally, rotate the ground support leg assembly 340 to its retracted position, as shown. Figure 16 (As shown). Finally, the folding table frame 310, the folding tabletop 400, and the crossbar 320, which are in the storage state, can be folded up together.

[0059] For example, the extension tube 113 of the umbrella assembly 100 can be inserted into the inner tube 332 of the central telescopic assembly 330. For instance, when the table assembly 200 is installed and deployed, because the mating port 410 of the folding tabletop 400 of the table assembly aligns with the tube segment 332c (described below) of the inner tube 332, the extension tube 113 can be inserted into the tube segment 332c of the inner tube 332 through the mating port 410. With the through hole 113a of the extension tube 113, the radial through hole of the inner tube 332, and the two radial through holes of the outer tube 331 aligned, the fixing pin 333 can be inserted into the aligned through hole to fix the umbrella assembly 100 and the table assembly 200 together, producing the umbrella-table assembly according to the embodiments of this application (e.g., Figure 1 (As shown).

[0060] Figure 9 An example of the application of an umbrella assembly 100 according to another embodiment of this application is illustrated. According to this example, the extension tube 113 of the umbrella assembly 100 (in the unfolded state) is inserted into the inner tube 332 of the central telescopic assembly 330 of the folding table frame 310. In this case, the desktop support leg assembly 350 of the folding table frame 310 is in a retracted state, but the ground support leg assembly 340 is in an unfolded state. Otherwise, the connection between the umbrella assembly 100 and the folding table frame 310 is the same as described above. Therefore, the folding table frame 310 can also be referred to as or used as an auxiliary support for the umbrella assembly 100, used alone to provide ground support for the umbrella assembly 100. In an alternative embodiment, when the folding table frame 310 is implemented as an auxiliary support for the umbrella assembly 100, the desktop support leg assembly can also be omitted from the folding table frame 310.

[0061] The umbrella assembly 100 of this application has a canopy diameter of up to 3.2 meters when unfolded and a length of up to 1.2 meters when folded, making it easy to store in a car or outdoor backpack, while meeting the needs of multiple people for sun or rain protection. The umbrella assembly 100 can be modularly integrated with the table assembly 200, facilitating diverse and flexible use scenarios.

[0062] When it is necessary to store the table assembly 200, the unfolded folding tabletop 400 can first be removed from the unfolded folding table frame 310 by pulling out the C-shaped clamp 412 from the crossbar 320. Then, the unfolded folding tabletop 400 can be rolled up as follows: Figure 6 In the folded state shown. Then, by loosening the fixing knob 363 of the locking device 360, the two crossbars 320 can be removed from the first tabletop support leg 351, as shown. Figure 2 As shown in Figure 3. Then, the desktop support leg assembly 350 can be rotated to its retracted state. Finally, the floor support leg assembly 340 can be rotated to its retracted state. Figure 7 (As shown). Finally, the folding table frame 310, the folding tabletop 400, and the crossbar 320, which are in the storage state, can be folded up together.

[0063] Although specific embodiments of this application are described in detail herein, they are provided for illustrative purposes only and should not be construed as limiting the scope of this application. Furthermore, those skilled in the art will understand that the various embodiments described herein can be used in combination with each other. Various substitutions, modifications, and alterations can be conceived without departing from the spirit and scope of this application.
