Description

Technical Field

[0001] This utility model relates to the field of furniture, and in particular to a height-adjustable folding table. Background Technology

[0002] In existing technologies, common folding table structures often use bolts, clips, or telescopic sleeves to adjust the height of the table legs. These structures suffer from cumbersome operation, time-consuming adjustments, and complex structures, making them particularly unsuitable for frequently changing usage scenarios. For example, in outdoor camping or small-apartment environments, where users require flexible table height to adapt to different uses (such as seated dining / standing work / children's activities), existing structures often fall short. Utility Model Content

[0003] The technical problem to be solved by this utility model is to provide a height-adjustable folding table, thereby solving the problem of difficulty in adjusting the height of the folding table during use.

[0004] To solve the above-mentioned technical problems, the technical solution adopted by this utility model is as follows: A height-adjustable folding table includes a tabletop and two symmetrically arranged linkage supports; The two connecting rod supports are respectively hinged to the tabletop, so that the connecting rod supports can rotate around the hinge point; during rotation, the two connecting rod supports move closer to each other and support each other to form a first form of the folding table; during rotation, the two connecting rod supports move further apart and respectively fit against the tabletop to support each other to form a second form of the folding table; the vertical height of the first form of the folding table is lower than the vertical height of the second form.

[0005] In some embodiments, the linkage support includes a first link and a second link, one end of the first link and one end of the second link are connected and form an included angle; the connecting ends of the first link and the second link are hinged to the tabletop so that the linkage support can rotate about the hinge point; the length of the second link is greater than that of the first link.

[0006] In some embodiments, in a first configuration, a first link in one of the linkage supports abuts against a second link in another linkage support; in a second configuration, the first links in both linkage supports abut against the tabletop.

[0007] In some embodiments, the first link and the second link are stacked together in the thickness direction, and the stacking directions of the first link and the second link of the two link supports are opposite.

[0008] In some embodiments, the tabletop is disposed in a limiting groove, and the limiting groove matches the abutment position of the first connecting rod and the tabletop.

[0009] In some implementations, the angle between the first link and the second link is an acute angle.

[0010] In some embodiments, the included angle between the first link and the second link is in the range of 50°-80°.

[0011] In some embodiments, each of the linkage supports includes two symmetrically arranged first linkages, two symmetrically arranged second linkages, and a stabilizing rod, with the two ends of the stabilizing rod connected to the two first linkages respectively. In some embodiments, both the first link and the second link have anti-slip pads at the ends that contact the ground.

[0012] In some embodiments, the tabletop has two parallel rotating shafts, and the two connecting rod supports are respectively hinged to the two rotating shafts.

[0013] The beneficial effects of this utility model are as follows: This folding table structure can achieve two different height modes by rotating the connecting rod support, namely a low state (such as a coffee table or children's table) and a high table state (such as a dining table or desk), without the need for external accessories to complete the adjustment, thus improving the adaptability and space utilization of the table. Compared with existing tables that use screw or pin-type height adjustment, this structure is easy to adjust, requires no tools, and is suitable for frequent scene switching.

[0015] To explain in detail the technical content, objectives, and effects of this utility model, the following description is provided in conjunction with the embodiments and accompanying drawings.

[0016] Please refer to Figures 1 to 4 A height-adjustable folding table includes a tabletop 1 and two symmetrically arranged linkage supports 2; The two connecting rod supports 2 are respectively hinged to the tabletop 1 so that the connecting rod supports 2 can rotate around the hinge point; during rotation, the two connecting rod supports 2 move closer to each other and support each other to form a first form of the folding table; during rotation, the two connecting rod supports 2 move further apart and respectively fit against the tabletop 1 to support each other to form a second form of the folding table; the vertical height of the first form of the folding table is lower than the vertical height of the second form.

[0017] As can be seen from the above description, the beneficial effects of this utility model are as follows: This folding table structure can achieve two different height modes by rotating the connecting rod bracket 2, namely a low state (such as a coffee table or children's table) and a high table state (such as a dining table or desk), without the need for external accessories to complete the adjustment, thus improving the adaptability and space utilization of the table. Compared with existing tables that use screw or pin-type height adjustment, this structure is easy to adjust, requires no tools, and is suitable for frequent scene switching.

[0018] In this embodiment, the folding table includes a tabletop 1 and two symmetrically arranged linkage supports 2. Each linkage support 2 is fixedly connected to the tabletop 1 via a rotating hinge. The user can manually lift one end of the tabletop 1 to cause the two linkage supports 2 to rotate synchronously. When the two supports cross in the middle and abut against each other, the tabletop 1 is in a lower position, forming the "first form"; if the two supports are rotated further until they open and contact the tabletop 1 for support, the height of the tabletop 1 increases, forming the "second form". This structure has wide application value in use cases such as small apartments, camping tables, and portable furniture. The entire conversion process requires no tools and can be completed by a single person.

[0019] In some embodiments, the linkage support 2 includes a first link 21 and a second link 22, one end of the first link 21 and one end of the second link 22 are connected and form an included angle; the connecting ends of the first link 21 and the second link 22 are hinged to the tabletop 1 so that the linkage support 2 can rotate about the hinge point; the length of the second link 22 is greater than that of the first link 21.

[0020] As described above, by setting different lengths for the first link 21 and the second link 22 and connecting them at a certain angle, the links have a clear trajectory during rotation, which helps to form two stable states (high / low). The longer design of the second link 22 makes it easier for users to perceive the difference between the first and second forms, simplifying the difficulty of use.

[0021] In some embodiments, in a first configuration, the first link 21 of one of the link supports 2 abuts against the second link 22 of the other link support 2; in a second configuration, the first link 21 of both link supports 2 abuts against the tabletop 1.

[0022] As described above, the structural contact relationship between the two states enables the table to have a self-positioning function when switching between the two states. Through direct contact between the support components or contact with the tabletop 1, sliding or misalignment of the support can be prevented. That is, the self-positioning function of the first and second forms can be achieved without manual positioning, further simplifying the use.

[0023] In the embodiment, in the first configuration, the short connecting rod at the intersection of the two supports contacts the long connecting rod of the other support to form a lower fulcrum; in the second configuration, the short connecting rod extends outward and presses against the bottom of the table 1 to form a diagonal brace, while the long connecting rod serves as an upright support leg, working together to ensure the stability of the overall structure.

[0024] In some embodiments, the first connecting rod 21 and the second connecting rod 22 are stacked and connected in the thickness direction, and the stacking directions of the first connecting rod and the second connecting rod of the two connecting rod supports 2 are opposite.

[0025] As can be seen from the above description, in order to avoid interference when the two linkage supports 2 are in contact in the first form, the first link 21 and the second link 22 are stacked in the thickness direction, and the stacking directions of the two linkage supports 2 are opposite. That is, from the perspective of the front view of the folding table, the stacking direction in one linkage support 2 is the first link 21-second link 22, and the stacking direction in the other linkage support 2 is the second link 22-first link 21. The setting of opposite stacking directions ensures that the contact trajectories of the linkage supports 2 do not interfere with each other when they are in contact in the first form.

[0026] In some embodiments, the tabletop 1 is disposed in a limiting groove, and the limiting groove matches the abutment position of the first connecting rod 21 and the tabletop 1.

[0027] As described above, the limiting groove design ensures that the connecting rod accurately aligns with the positioning area under the tabletop 1 when extended, preventing instability of the tabletop due to sliding or bracket displacement during use, thus improving structural durability and user safety. In this embodiment, a concave limiting groove is pre-formed at the bottom of the tabletop 1, with a depth matching the thickness of the first connecting rod 21. When the table is in a high position, the first connecting rod 21 is embedded in the limiting groove, serving as a stop and limiting mechanism. This structure improves positioning accuracy through mechanical cooperation.

[0028] In some embodiments, the included angle between the first link 21 and the second link 22 is an acute angle.

[0029] As described above, setting an acute angle (50°-80°) between the first and second connecting rods 22 allows for a smaller folding space while enhancing the stability of the triangular structure in the high-position state. Limiting the angle range helps optimize the load-bearing path, balancing the conflict between stability and compact folding. After the connecting rods are assembled, they connect to form an angle of approximately 60°. In the first state, this angle makes the support easy to fold; in the second state, the angle flattens to form an expanded support, maintaining a suitable inclination to support the tabletop 1.

[0030] In some embodiments, each of the linkage brackets 2 includes two symmetrically arranged first linkages 21, two symmetrically arranged second linkages 22, and a stabilizing rod 23, with the two ends of the stabilizing rod 23 respectively connected to the two first linkages 21. As described above, the symmetrically arranged double-link structure connected to the stabilizer 23 forms a rigid triangular overall frame, significantly improving the load-bearing capacity and anti-sway ability of the table in a high position, effectively suppressing structural deformation and instability. For example, each side support has two sets of symmetrical links, respectively arranged on both sides below the tabletop 1, and a stabilizer 23 laterally connects the middle sections of the two first links 21, forming a trapezoidal frame structure, which exhibits superior stability under high-intensity usage scenarios.

[0031] In some embodiments, the ends of the first link 21 and the second link 22 that are in contact with the ground are provided with anti-slip pads.

[0032] As described above, installing anti-slip mats prevents the table from slipping when its supporting legs contact the ground, regardless of the table's height, thus improving its safety, especially important on smooth surfaces or wet outdoor terrain. For example, installing rubber pads or silicone sleeves at the bottom of each link provides elasticity and a certain coefficient of friction, allowing it to adapt to various surfaces such as tiles, floors, and grass, preventing the table from shifting or tipping over during use.

[0033] In some embodiments, the tabletop 1 is provided with two parallel rotating shafts 3, and the two connecting rod supports 2 are respectively hinged to the two rotating shafts 3.

[0034] As can be seen from the above description, the use of a dual rotating shaft 3 structure makes the connection between each connecting rod bracket 2 and the tabletop 1 more robust and has synchronous rotation characteristics, improving the durability of the structure and the feel of operation, while also facilitating left and right synchronous switching.

[0035] In summary, the height-adjustable folding table provided by this utility model, through its innovative linkage bracket design, allows for switching between two table heights without disassembling any parts. Compared to traditional structures that manually adjust the table leg length or use a lifting mechanism, this utility model not only boasts a simple structure, low manufacturing cost, and convenient adjustment operation, but also possesses excellent folding compactness and high-position stability. This structure is particularly suitable for space-sensitive office, home, or outdoor settings, and has broad application prospects and market value.

[0036] The above description is merely an embodiment of this utility model and does not limit the patent scope of this utility model. Any equivalent modifications made based on the content of this utility model specification and drawings, or direct or indirect applications in related technical fields, are similarly included within the patent protection scope of this utility model.
