[0002] With the continuous development of furniture design and manufacturing technologies, various types of functional tables are gradually finding their way into people's daily lives. Extendable tables, in particular, are widely used in scenarios with high demands on space efficiency, as their usable surface area can be expanded. Common extendable tables typically consist of a main table body and a fold-out extension leaf, with the extension, unfolding, and locking of the leaf being achieved through special mechanical mechanisms.

[0003] To achieve the upward tilting and unfolding movement of the pull-out tray, prior art typically employs complex linkage mechanisms or slide rail guide systems. These structures often require the interaction of several compatible components, such as guide grooves, rollers, hinges, and elastic elements, to ensure that the pull-out tray can smoothly transition from its horizontal storage state to its tilted operating state during the unfolding process. Because this process relies on precise component matching and motion control, the entire opening mechanism is relatively complex, assembly is difficult, and high demands are placed on the machining accuracy and durability of the parts.

[0022] This embodiment is suitable for a folding extendable table with a tilting lever. After opening the extendable table with a tilting lever, the tabletop has a square, round, oval, or barrel shape. This embodiment is explained using the example of a square extendable table with a tilting lever. The lower part of the extendable table with a tilting lever is a leg frame. The leg frame is generally known in this field and is not described in detail here.

[0023] Referring to Fig. 1 and Fig. 2 This embodiment provides a folding table extension table with a tilting lever, wherein the folding table extension table with tilting lever comprises a main table top 100, a sliding frame 200 and side table tops 300.

[0024] The main tabletop 100 is rectangular.

[0025] The sliding frame 200 is movable relative to the main tabletop 100 along a first direction between a first position and a second position. In the first position, the sliding frame 200 is concealed beneath the main tabletop 100, and in the second position, the sliding frame 200 protrudes from the main tabletop 100.

[0026] The sliding frame 200 is provided with at least two pairs of sliding grooves, the sliding grooves in each pair extending along the first direction.

[0027] Referring to Fig. 3 and Fig. In Figure 4, the sliding frame 200 is rectangular and comprises a first connecting part 210, a second connecting part 220, a third connecting part 230, and a fourth connecting part 240. The first connecting part 210 is arranged parallel to the second connecting part 220, the third connecting part 230 is arranged parallel to the fourth connecting part 240, and the third connecting part 230 is perpendicular to the first connecting part 210. The third connecting part 230 and the fourth connecting part 240 are each provided with sliding grooves, with a sliding groove on the third connecting part 230 and a sliding groove on the fourth connecting part 240, which lie on the same straight line, forming a pair.

[0028] In the second direction, the displacement vectors L of the two pairs of sliding grooves are equal, and in a third direction, which is perpendicular to both the first and second directions, the displacement vectors H of the two pairs of sliding grooves are equal.

[0029] A sliding path of a first pair from the sliding grooves 201 comprises an inclined upward section 201a and a horizontal section 201b. In the second direction, the ratio of a displacement vector of the inclined upward section 201a to a displacement vector of the horizontal section 201b is 7:1.

[0030] The first pair of sliding grooves 201 and a second pair of sliding grooves 202 are arranged one behind the other along the second direction (the opening direction of the side table tops). One sliding path of the second pair of sliding grooves 202 comprises an inclined section 202a, an arcuate section 202b, and a horizontal movement section 202c. In the second direction, the ratio of a displacement vector of the inclined section 202a, a displacement vector of the arcuate section 202b, and a displacement vector of the horizontal movement section 202c is 1:1:5.

[0031] For better understanding, the individual sections are divided into Fig. 4 divided by dashed lines. During actual unfolding, the second pair of sliding grooves 202 acts as the drive sliding groove and the first pair of sliding grooves 201 as the follower sliding groove. In this embodiment, precise calculations and simulation experiments with the aforementioned sliding path design allow the heavier side table panels 300 to move very smoothly along the sliding path. Due to the arrangement of the inclined section 202a and the arcuate section 202b in this embodiment, the end of the side table panels 300 tilts upwards during the opening process, thus preventing them from colliding with the frame body of the sliding frame 200. Furthermore, no additional auxiliary mounting elements are required to control the opening angle, resulting in a simple assembly.

[0032] Referring to Fig. In this embodiment, the sliding frame 200 is slidably connected to the main table top 100 by two groups of three-part rails 400. The two groups of three-part rails 400 are arranged symmetrically along the centerline of the main table top 100, with the centerline running perpendicular to the second direction. Each group of three-part rails 400 comprises a first slide rail 410, a second slide rail 420, and a third slide rail 430, which are slidably connected one after the other. The two first slide rails 410 are each fixedly connected to the main table top 100. One of the third slide rails 430 forms the first connecting part 210, and one of the third slide rails 430 forms the second connecting part 220.

[0033] The design of the three-part rails 400 can meet the requirements of various shapes of folding table extension tables with tilt levers and is adaptable to leg frames of folding table extension tables with tilt levers of different shapes.

[0034] In some other embodiments, a sliding connection can be used by means of two-part rails.

[0035] Referring to Fig. 1, Fig. 2 and Fig. In this embodiment, the secondary table panels 300 are mounted in the frame of the sliding frame 200, meaning that the secondary table panels 300 slide with the sliding frame 200 along the first direction. If the sliding frame 200 protrudes from the main table panel 100, the secondary table panels 300 also protrude from the main table panel 100. Therefore, in this embodiment, an extension is made on one side of the main table panel 100.

[0036] In some other embodiments, a secondary table top 300 can be provided on both sides of the main table top 100 in order to achieve a length extension on both sides.

[0037] In some embodiments, the main tabletop 100 is divided into two table bodies, with a secondary tabletop 300 arranged between the two table bodies. The two table bodies are pulled apart, and then the secondary tabletop 300 is unfolded to achieve the extension. When storing the table, the two table bodies are pushed together, and the secondary tabletop 300 is located beneath them.

[0038] In this embodiment, the first direction can be defined as the longitudinal direction of the main tabletop 100. The secondary tabletop 300 represents a longitudinal extension of the main tabletop 100, thus increasing the length of the folding tabletop extension table with tilting lever and enlarging the usable surface area of ​​the folding tabletop extension table with tilting lever.

[0039] The secondary table top 300 is provided with sliding shafts 330 on one side facing away from the main table top 100. The number of sliding shafts 330 is equal to the number of pairs of sliding grooves and corresponds to them one-to-one. Both ends of a sliding shaft 330 are arranged in the same pair of sliding grooves.

[0040] This embodiment uses a double sliding groove design, i.e., the number of sliding shafts 330 is two. The first sliding shaft is located in the first pair of sliding grooves 201, and the second sliding shaft is located in the second pair of sliding grooves 202. The first sliding shaft serves as the drive sliding shaft (i.e., primary sliding), and the second sliding shaft serves as the follower sliding shaft (i.e., assisting sliding). Compared to the prior art, which provides only one sliding shaft, this embodiment can improve the smoothness of the sliding action.

[0041] This embodiment utilizes the interaction of double sliding grooves and double sliding shafts to guide the movement of the side table top 300, allowing the side table top 300 to slide and tilt upwards smoothly, thus simplifying operation. It is understood that the sliding paths of the two pairs of sliding grooves designed in this embodiment are different. Compared to the prior art, where a pull-out panel is guided by a single sliding groove, this embodiment increases the number of sliding shafts 330, which corresponds to an increase in the number of sliding support points and can improve the smoothness of the movement of the side table top 300.

[0042] Furthermore, in this embodiment, the components under the side table top 300 are simplified, the space required for the components is reduced, and space is created for mounting the table legs. This allows for adaptation to different types of table legs, increases the flexibility of the design, and meets the requirements of various application scenarios.

[0043] In some embodiments, the number of side table panels 300 is two. The side table panels 300 comprise a first side table panel 310 and a second side table panel 320. The sliding shaft 330 is arranged on the side of the first side table panel 310 facing away from the main table panel 100. In this embodiment, the two sliding shafts 330 serve as support elements for the first side table panel 310, which improves the stability of the first side table panel 310 after opening. At the same time, this embodiment does not require the design of additional support elements, which has the advantage of a simplified structure and reduces production and assembly processes.

[0044] The second side table top 320 is hinged to the first side table top 310 and folded onto one side of the first side table top 310 that faces the main table top 100. In this embodiment, the dimensions of the first side table top 310 and the second side table top 320 are the same. The first side table top 310 and the second side table top 320 are hinged to each other by means of hinges 340, with several hinges 340 being spaced apart along the longitudinal direction of the side table tops 300.

[0045] Referring to Fig. 3, Fig. 5 and Fig. The side table tops 300 further comprise a support shaft 350 and a connecting piece 360. One end of the connecting piece 360 ​​is rotatably connected to the support shaft 350, and the other end of the connecting piece 360 ​​is rotatably connected to the second side table top 320. Folding out the second side table top 320 causes the respective sliding shafts 330 to slide.

[0046] As described above, a coupling is achieved by applying a force to the second side table 320: firstly, the opening of the second side table 320 relative to the first side table 310, and secondly, the sliding of the first side table 310 relative to the sliding frame 200 along the second direction.

[0047] After opening the folding-top extension table with tilting lever, in the first direction the length of the second side tabletop (320) is equal to the length of the first side tabletop (310), the extension length is equal to the length of the second side tabletop (320), and the extension length is also equal to the length of the first side tabletop (310). At this point, the total length of the folding-top extension table with tilting lever is the sum of the length of the main tabletop (100) and the extension length.

[0048] After opening the folding table extension with tilt lever, in the second direction the width of the second side table top 320 is equal to the width of the first side table top 310, the extension width is equal to the sum of the width of the second side table top 320 and the width of the first side table top 310, and the extension width is also equal to the width of the main table top 100.

[0049] When the secondary table tops 300 are slid and opened along a second direction perpendicular to the first, the sliding shafts 330 slide in the sliding grooves. When the sliding has reached the end position, the surfaces of the secondary table tops 300 lie in the same horizontal plane as the surface of the main table top 100.

[0050] Specifically, when folded, the surface of the second side tabletop 320 rests against the surface of the first side tabletop 310. After unfolding the second side tabletop 320, its surface gradually moves away from the surface of the first side tabletop 310 until both lie in the same horizontal plane. The connection position of the hinges 340 is the adjacent position of the first side tabletop 310 and the second side tabletop 320.

[0051] In some embodiments, the folding-plate extendable table with tilting lever further comprises a first leveling element 500 and a second leveling element 600. The first leveling element 500 and the second leveling element 600 can each be adjusted in height along their axis direction.

[0052] The first leveling element 500 and the second leveling element 600 are arranged on the side of the side table tops 300 facing away from the main table top 100. When the sliding mechanism has reached its end position, the first leveling element 500 is located between the side table tops 300 and the first connecting part 210, and the second leveling element 600 is located between the side table tops 300 and the second connecting part 220.

[0053] Specifically, the first leveling element 500 is located between the first side table top 310 and the first connecting part 210, and the second leveling element 600 is located between the second side table top 320 and the second connecting part 220, i.e. the first leveling element 500 has the function of adjusting the height of the surface of the first side table top 310, and the second leveling element 600 has the function of adjusting the height of the surface of the second side table top 320.

[0054] By arranging the first leveling element 500 and the second leveling element 600 in this embodiment, the height of the tabletop can be adjusted after the folding-table extension table with tilting lever has been mounted, ensuring that the first secondary tabletop 310, the second secondary tabletop 320, and the main tabletop 100 lie in the same horizontal plane. This reduces the requirements for manufacturing and assembly accuracy and saves costs.

[0055] In practical application, the first leveling element 500 and the second leveling element 600 are each connected via bolts to the side of the secondary table tops 300 facing away from the main table top 100. The height adjustment of the first leveling element 500 and the second leveling element 600 is achieved by adjusting the length of the connection between the bolt and the secondary table top 300.

[0056] The height here refers to the relative position between the first leveling element 500 and the side table tops 300, as well as the relative position between the second leveling element 600 and the side table tops 300. The side table top 300 is provided with a first mounting hole and a second mounting hole. The first leveling element 500 is positioned in the first mounting hole, and the second leveling element 600 is positioned in the second mounting hole.

[0057] Referring to Fig. 3, Fig. 4 to Fig. 5. The sliding shafts 330 slide along the second direction relative to the sliding grooves between an initial position and an end position. In the end position, the dimension of the sliding groove is larger than the dimension of the sliding shaft 330. At positions outside the end position, the sliding groove and the sliding shaft 330 have a clearance fit.

[0058] As mentioned above, the dimension of the sliding groove in the end position is larger than the dimension of the sliding shaft 330. This means that the sliding shaft 330 can move up and down in the sliding groove when it is in the end position. This allows it to be adjusted to different heights of the first leveling element 500 and the second leveling element 600, thus providing sufficient adjustment range to ensure the flatness of the tabletop of the folding-top extendable table with tilting lever.

[0059] Based on the above, the operating principle of the folding tabletop extension table with tilting lever is further explained in this exemplary embodiment: As in Fig. Figure 1 shows the folded state of the folding tabletop extension table with tilting lever. The in Fig. The seven side table tops 300 shown are completely hidden beneath the main table top 100. Slide the sliding frame 200 along the first direction so that the sliding frame 200 and the side table tops 300 protrude completely from the main table top 100. See Fig. 8.

[0060] S200. Folding the second side table top 320 upwards. While the second side table top 320 is being folded upwards relative to the first side table top 310, the first side table top 310 slides relative to the sliding frame 200 along the second direction.

[0061] See Fig. 9. When the sliding has reached the end position, the first side table top 310, the second side table top 320 and the main table top 100 lie in the same horizontal plane.

[0062] By mounting the side table panels 300 in the sliding frame 200 and connecting the sliding frame 200 to the main table panel 100, this embodiment achieves two states: one in which the side table panels 300 are concealed beneath the main table panel 100 and the other in which they protrude from it. Furthermore, this embodiment utilizes the arrangement of two pairs of sliding grooves and two sliding shafts 330 to simultaneously enable sliding and upward tilting, simplifying the unfolding and stowing processes and reducing operating difficulty. The folding-panel extendable table with tilting lever provided in this embodiment features a sliding and folding structure that meets the requirements of various table types for the functionality of the side table panels 300, such as: a single-sided extension structure, a centrally coupled single-sided extension structure, and a central extension structure.
