Description

Technical Field

[0001] The present invention relates to the technical field of furniture, and particularly to a folding table. Background Art

[0002] In daily life, folding tables are widely used. Generally, folding tables adopt a flip-type folding method, and the proportion of the seat frame and the tabletop size is relatively fixed. When the tabletop is large, a relatively larger table frame needs to be selected to ensure the stability of the tabletop support, which results in a relatively large overall volume of some folding tables, making it inconvenient for people to use and having relatively single functions. Summary of the Invention

[0003] In order to solve the above technical problems, the purpose of the present invention is to provide a folding table, which solves the problem that the existing folding table has a relatively large overall volume.

[0004] In order to achieve the above purpose, the technical solution adopted by the present invention is: a folding table, including a tabletop and a table frame supporting the tabletop. The tabletop includes a first tabletop and a second tabletop. The first tabletop and the second tabletop are hinged and slidably connected to the table frame, so that when the first tabletop slides, the tabletop can be unfolded on the table frame or folded along the hinge of the first tabletop and the second tabletop. The folding table further includes a leg frame and a linkage mechanism. The leg frame is rotatably connected to the table frame to support the tabletop when the tabletop is unfolded. The linkage mechanism is used to synchronously rotate the leg frame when the first tabletop slides on the table frame, so that the leg frame switches between the support position for supporting the tabletop and the folding position folded onto the table frame.

[0005] Furthermore, the leg frames are arranged on both sides of the table frame along the sliding direction of the tabletop. Arranging the leg frames on both sides of the table frame facilitates the stable support of the tabletop after the tabletop is unfolded and laid on the table frame.

[0006] Furthermore, the linkage mechanism includes a first gear, a gear set, and a transmission belt connecting the first gear and the gear set. The first gear is sleeved on the leg frame on one side of the table frame, the gear set is connected to the leg frame on the other side of the table frame, and the transmission belt moves with the displacement of the tabletop. When the tabletop displaces, the first gear and the gear set are synchronously rotated through the transmission belt, so that the leg frames are unfolded or folded on the table frame. During the process of the tabletop sliding on the table frame to be unfolded and laid, the leg frames are synchronously driven to unfold through the linkage mechanism, which is more convenient for the use of the folding table.

[0007] Furthermore, the gear set includes a second gear, a driving gear rotatably arranged on the table frame, and a driven gear coaxially arranged with the driving gear. The driving gear meshes with the transmission belt, and the second gear is sleeved on the leg frame and meshes with the driven gear. By using the setting of the gear set, the two leg frames at both ends of the transmission belt can be kept rotating synchronously and in opposite directions, so as to quickly unfold the two leg frames.

[0008] Furthermore, a fixing component is provided on the table frame. The fixing component is detachably connected to the conveyor belt and is used to drive the conveyor belt to actuate when the tabletop is displaced. The setting of the fixing component facilitates the connection between the tabletop and the conveyor belt, and further drives the conveyor belt to operate when the tabletop moves.

[0009] Furthermore, the fixing component includes a fixing block and a screw. The fixing block is provided with a through hole for the conveyor belt to pass through, and the screw threadedly penetrates the through hole to fasten the conveyor belt to the fixing block. The way that the screw penetrates the fixing block to connect the fixing block and the conveyor belt facilitates the disassembly of the two and the change of the joint point between the conveyor belt and the fixing block.

[0010] Furthermore, the leg frame includes a rotating shaft and a support rod connected to the rotating shaft for supporting the tabletop. The leg frame is rotatably connected to the table frame through the rotating shaft. The rotating shaft facilitates the rotation of the leg frame on the table frame, while the support rod facilitates the support of the tabletop.

[0011] Furthermore, a connecting component is provided between the leg frame and the tabletop. The connecting component is used to relatively fix the support rod and the tabletop when the tabletop is unfolded. The setting of the connecting component facilitates the limitation of the rotation angle of the leg frame, improves the support stability of the leg frame for the tabletop, and avoids the leg frame from shaking when supporting the tabletop.

[0012] Furthermore, the connecting component includes any one of snap connection, magnetic connection, and adhesive connection. This connection method facilitates the connection and disassembly of the two, and further facilitates the folding and storage of the folding table.

[0013] Furthermore, the tabletop and the table frame are slidably connected through a linear track. The linear track facilitates the sliding of the tabletop on the table frame, and also facilitates the limitation of the sliding distance of the tabletop on the table frame, avoids the separation of the tabletop from the table frame, and improves the stability and smoothness of the sliding of the tabletop on the table frame.

[0014] Compared with the prior art, the advantages of the present invention are as follows: By rotatably providing a leg frame on the table frame, when the tabletop is laid on the table frame, the leg frame can be unfolded on the table frame to support the tabletop, and after the tabletop is folded and stored, the leg frame can also rotate around the table frame, so that the leg frame can be stored on the table frame, effectively reducing the volume of the folding table and effectively solving the problem of the relatively large overall volume of the folding table with a large tabletop.

[0015] In the present invention, the tabletop includes a first tabletop and a second tabletop. The two tabletops are hinged, enabling the tabletop to be folded along the hinge joint of the two tabletops. Thus, when the folding table is only for personal use, the usable area of the tabletop can be changed. When multiple people use it, the tabletop can also be slid on the tabletop to expand the tabletop to meet the needs of multiple people, effectively enhancing the practicality of the folding table. At the same time, after the tabletop is bent, the bent tabletop cooperates with the table frame and can also be used as a single-sided cabinet, increasing the usage purposes of the folding table and making the folding table more practical and convenient.

[0016] In the present invention, the setting of the linkage mechanism can drive the two leg frames to unfold after rotation during the sliding of the tabletop on the table frame, thereby supporting the unfolded tabletop. Its setting greatly facilitates the use of the folding table. Without manual operation of unfolding or folding the leg frames, the corresponding leg frames can be automatically retracted and unfolded during the unfolding or storage of the tabletop on the table frame, making it more convenient for personnel to operate and use the folding table, and effectively improving the operation efficiency of the folding table.

[0030] The present invention will be further described in detail below in conjunction with the embodiments with reference to the drawings.

[0031] Refer to Figure 1 , the folding table includes a table frame 200 and a tabletop 100 provided on the table frame 200. The tabletop 100 includes a first tabletop 110 and a second tabletop 120. One side of the first tabletop 110 is hinged to one side of the second tabletop 120 through a hinge, thereby forming the tabletop 100. The first tabletop 110 is slidably connected to the table frame 200, and the two are connected through a linear guide rail so that the tabletop 100 can slide on the table frame 200. When the first tabletop 110 slides, it will simultaneously drive the second tabletop 120 hinged thereto to move on the table frame 200. When both the first tabletop 110 and the second tabletop 120 are provided on the table frame 200, the tabletop 100 is arranged flat on the table frame 200 (as Figure 3 shown), and only when the first tabletop 110 is provided on the table frame 200, the second tabletop 120 lacks support, and the second tabletop 120 can be bent relative to the first tabletop 110, so that the second tabletop 120 will fold to the front side of the table frame 200, (as Figure 1 shown), and in order to improve the support stability of the table frame 200 for the tabletop 100 after the tabletop 100 is unfolded, a leg frame 300 is provided in the sliding direction of the tabletop 100. (This direction is also the two sides of the length direction of the cubic table frame 200), and the leg frame 300 can rotate around its rotation connection point with the table frame 200, so as to facilitate the folding of the table legs onto the table frame 200 or the unfolding from the table frame 200. When the leg frame 300 is unfolded, it will support the first tabletop 110 and the second tabletop 120 after the tabletop 100 is unfolded, thereby improving the stability of the tabletop 100 when it is laid flat. This design does not require the table frame 200 itself to be designed larger to support the large-area tabletop 100. It can complete the support of the large-size tabletop 100 only through the folding and unfolding of the leg frame 300 on the table frame 200, effectively reducing the product volume and saving production costs.

[0032] In this embodiment, refer to Figure 2, the tripod 300 includes a rotating shaft 310 and a support rod 320 connected to the rotating shaft 310. The two are arranged in a rectangle. The tripod 300 is rotatably connected to the front and rear sides of the table frame 200 through the rotating shaft 310, and its support rod 320 can rotate on the side of the table frame 200 through the rotating shaft 310, so that the tripod 300 can be folded and closed to the table frame 200, or extended to support the tabletop 100 after extension.

[0033] In this embodiment, referring to Figure 1 and 2 , in order to make the folding table more convenient to unfold or fold and store, a linkage mechanism is provided on the table frame 200 and the first tabletop 110. During the process of the first tabletop 110 sliding on the table frame 200, the tripod 300 is driven to move synchronously through the linkage mechanism. Furthermore, after the tabletop 100 is moved and unfolded, the tripod 300 can also be opened synchronously on the table frame 200 to support the tabletop 100. At the same time, when the tabletop 100 moves in the reverse direction of the unfolding direction to fold, the tripod 300 can also be folded onto the table frame 200 synchronously. With this driving mechanism, the unfolding and folding storage of the folding table are greatly facilitated, and the operation and use efficiency of the table frame 200 are effectively improved.

[0034] When the linkage mechanism drives the tripod 300 to rotate on the table frame 200 to unfold, the two tripods 300 can rotate in the same direction or in opposite directions. In this embodiment, the two tripods 300 rotating in the same direction and in opposite directions are respectively taken as examples for illustration.

[0035] When the two table legs 300 rotate in opposite directions, referring to Figure 2 and 5, The linkage mechanism includes a first gear 520, a gear set 530, and a transmission belt 500 that links the first gear 520 and the gear set 530. For ease of description, the leg 300 in front of the table frame 200 is named the first leg 301, and the corresponding leg on the opposite side of the first leg 301 is called the second leg 302. The first gear 520 is sleeved on the rotating shaft 310 of the first leg 301. The gear set 530 includes a second gear 531, a driving gear 532 rotatably provided on the table frame 200, and a driven gear 533 coaxially arranged with the driving gear 532. The second gear 531 is sleeved on the rotating shaft 310 of the second leg 302. A fixing component is provided at the bottom of the first tabletop 110, and is connected to one side of the transmission belt 500 by using the fixing component, so that when the tabletop 100 moves, it can drive the transmission belt 500 to run. The driving gear 532 can be rotatably connected to the table frame 200 through a rotating shaft, so that when the transmission belt 500 moves, the driving gear 532 can rotate on the table frame 200. The driven gear 533 is coaxially arranged with it and rotates synchronously with the rotation of the driving gear 532. When the driven gear 533 rotates, it drives the second gear 531 sleeved on the second leg 302 to rotate. Furthermore, when the transmission belt 500 runs, the first gear 520 and the second gear 531 at both ends of the transmission belt 500 can rotate synchronously and in opposite directions, thereby realizing the simultaneous and opposite rotation of the two legs 300, achieving the purpose of the two legs 300 rotating synchronously to unfold or fold on the table frame 200.

[0036] Refer to Figure 2 and 5 , In this embodiment, both ends of the transmission belt 500 are wound around the first gear 520 and the driving gear 532 in sequence and form a loop. The operation of the transmission belt 500 depends on the movement of the first tabletop 110.

[0037] Refer to Figure 6 , When the two legs 300 rotate in the same direction, different from Embodiment 1, in Embodiment 1, the first leg 301 and the second leg 302 are on the same side of the extension direction of the transmission belt 500. When the two legs 300 rotate in opposite directions, the first leg 301 and the second leg 302 are on both sides of the extension direction of the transmission belt 500. The gear set 530 includes a single gear sleeved on the rotating shaft 310 of the second leg 302. In this way, when the transmission belt 500 runs, the two legs 300 can also be unfolded or folded synchronously, and the above effects can also be achieved.

[0038] In the above embodiment, the fixing assembly includes a fixing block 510 and a screw 512. A through hole 511 is penetrated inside the fixing block 510. One side of the transmission belt 500 passes through the through hole 511. The screw 512 is screwed in the radial direction of the through hole 511. The screw 512 is screwed into one side of the fixing block 510 to tighten the transmission belt 500 and the fixing block 510 relative to each other, thereby realizing a detachable connection between the fixing block 510 and the transmission belt 500. Of course, it can be imagined that the detachable connection between the fixing assembly and the transmission belt 500 can also be installed by snap-fitting, bonding and other installation methods, which will not be elaborated here.

[0039] In this embodiment, due to the connection position between the transmission belt 500 and the fixed block 510, the position of the connection point between the two can be adjusted by tightening and loosening the screw 512. Therefore, the rotation and expansion angle of the two legs 300 can also be adjusted by changing the connection point position between the transmission belt 500 and the fixed block 510. Preferably, when the first table top 110 moves from the folded position to reach the extreme position, that is, when the table top 100 and the table frame 200 are completely unfolded, the transmission belt 500 drives the two legs 300 to move from the folded position to the best position perpendicular to the side of the legs 300, so as to maintain the two legs 300 at a standard expansion angle with the table frame 200 after unfolding, so as to facilitate the uniform support of the two table legs on the table top 100.

[0040] It can be imagined that in order to enable the two legs 300 to be simultaneously unfolded to support the desktop 100 when the desktop 100 is moved, thereby achieving the purpose of facilitating the rapid unfolding or folding of the folding table, the linkage mechanism of this embodiment adopts a belt drive method. Of course, its linkage mechanism can also be a chain drive, a gear drive or a connecting rod drive. Based on the technical inspiration of realizing the rapid use of the table frame 200 by linking the legs 300 when the desktop 100 moves, other linkage methods are also within the protection scope of this application.

[0041] In this embodiment, the table top 100 and the foot frame 300 are connected by sliding connection via a linear track. Specifically, the linear track may be: a slide bar 410 is provided on the table frame 200, and a slide seat 400 is provided on the table frame 200. A slide hole is provided inside the slide seat 400, and the slide bar 410 slides through the slide hole. The sliding cooperation of the two is utilized to realize the sliding of the table top 100 on the table frame 200. At the same time, the sliding distance of the linear track is fixed to limit the displacement limit distance of the first table top 110 on the table frame 200, so as to prevent the first table top 110 from detaching from the table frame 200 when sliding.

[0042] Of course, the linear track can also adopt existing sliding methods such as slide rails, cylinders, etc., as long as it can enable the desktop 100 and the table frame 200 to move smoothly. The linear track can also adopt other operating methods.

[0043] Based on the above embodiments, refer toFigure 3 and 4 In order to facilitate the stable connection between the tripod 300 and the unfolded tabletop 100 after the tripod 300 is unfolded, so as to ensure that the tripod 300 can stably support the tabletop 100, and at the same time facilitate the precise limitation of the movement angle of the tripod 300, a connecting component is provided between the tripod 300 and the tabletop 100. After the tabletop 100 is unfolded in place, the connecting component relatively fixes the table frame 200 and the tripod 300 to improve the stable support of the tripod 300 for the tabletop 100.

[0044] Specifically, referring to Figure 4 The connecting component includes clamping seats provided at the bottoms of the first tabletop 110 and the second tabletop 120. A plurality of limiting grooves 610 are formed in the circumferential direction of the clamping seats, and a clamping block 611 that is in clamping fit with the limiting grooves 610 is provided at the end of the support rod 320 of the tripod 300. By using the clamping fit between the clamping block 611 and the limiting grooves 610, the above-mentioned purpose of stably fixing the tripod 300 and the tabletop 100 is achieved. At the same time, when the two are disassembled, they can also be quickly separated. Of course, the connecting component can also adopt other detachable fixing methods, including setting magic tapes on the ground surfaces of the tripod 300 and the table frame 200 respectively, and realizing the connection between the two by pasting them, or the two are connected by a magnetic attraction method, and magnets are respectively provided on the table frame 200 and the table legs, and the limiting connection between the two is realized by the magnetic attraction of the magnets.

[0045] In this embodiment, the table frame 200 is an overall cubic structure and is assembled by a plurality of rectangular frames. Actually, according to the use requirements, the table frame 200 can be designed as a frame with a plurality of cavities, so as to facilitate the use of the cavities to place items and improve the practicability of the folding table. Of course, it can be imagined that the frame can also be of other shapes and structures.

[0046] Based on the above embodiment, in order to facilitate the more stable sliding of the tabletop 100 on the table frame 200, auxiliary rollers 700 can be provided at the joint between the table frame 200 and the tabletop 100, changing the sliding between the tabletop 100 and the table frame 200 into rolling, making the tabletop 100 slide more smoothly, and at the same time, the sliding distance of the tabletop 100 on the table frame 200 can also be limited by the setting of the auxiliary rollers 700.

[0047] Specifically, referring to Figure 4, auxiliary rollers 700 can be respectively arranged on the bottom surface and the inner side of the table frame 200. The auxiliary rollers 700 on the bottom surface are in contact with the outer side of the tabletop 100 to reduce the sliding resistance between the side surface of the tabletop 100 and the table frame 200. At the same time, the auxiliary rollers 700 on the bottom surface can also be used to prevent the tabletop 100 from shaking on the front and rear sides of the table frame 200. The auxiliary rollers 700 located inside the table frame 200 are in contact with the bottom of the tabletop 100, thereby reducing the sliding friction between the bottom of the tabletop 100 and the table frame 200, being more conducive to the sliding of the tabletop 100, and also being able to support the bottom of the tabletop 100.

[0048] In the above embodiment, the tabletop 100 is composed of a first tabletop 110 and a second tabletop 120 hinged together. It can be imagined that the tabletop 100 can also adopt a combination method of multiple tabletops 100 hinged together. The tabletop 100 can be a combination of three surfaces in sequence or a combination of four surfaces hinged together. As long as it can meet the normal operation and use of the tabletop 100 on the table frame 200, the tabletop 100 can also be in the form of a combination of multiple surfaces.

[0049] Although the preferred embodiments of the present invention have been described in detail above, it should be clearly understood that various changes and modifications can be made to the present invention by those skilled in the art. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present invention shall be included within the protection scope of the present invention.
