Description

Technical Field

[0001] The present application relates to the technical field of folding tables, and in particular to a folding support leg and a folding table. Background Art

[0002] A folding table is a table that can be folded and stored. It originated from the portable furniture design in ancient times. As time goes by, the design and manufacture of folding tables have continued to improve, from the initial simple folding structure to the modern multi-functional and multi-purpose design. Now folding tables are widely used not only in homes, but also in offices, market stalls, outdoor camping and many other occasions.

[0003] However, the folding legs of the existing folding table are generally mainly interlocked after being spread out. Although this structure can interlock when the legs are spread out, it cannot prevent the legs from swinging or folding inwards due to other reasons, causing the folding table to suddenly fall over during use. Of course, the folding legs of the folding table are also provided with components that can fix the fixing structure to prevent the folding legs from accidentally retracting after being spread out. However, these fixing components require multiple steps to fix the folding legs in actual operation, which is troublesome to operate and inconvenient to use. Summary of the invention

Detailed implementation manners

[0043] Next, in combination with the detailed implementation manners, the present application will be further described. It should be noted that, on the premise of no conflict, the following-described embodiments or technical features can be arbitrarily combined with each other to form new embodiments.

[0044] In the description of the present application, it should be noted that for orientation terms, such as terms "center", "transverse", "longitudinal", "length", "width", "thickness", "upper", "lower", "front", "rear", "left", "right", "vertical", "horizontal", "top", "bottom", "inner", "outer", "clockwise", "counterclockwise", etc., the orientation and position relationships indicated are based on the orientation or position relationships shown in the drawings. It is only for the convenience of describing the present application and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and should not be construed as limiting the specific protection scope of the present application.

[0045] It should be noted that the terms "first", "second", etc. in the description and claims of the present application are used to distinguish similar objects, and do not necessarily need to describe a specific order or sequence.

[0046] The terms "comprising" and "having" in the description and claims of the present application and any variations thereof are intended to cover non-exclusive inclusion. For example, a process, method, system, product or device comprising a series of steps or units does not necessarily have to be limited to those steps or units clearly listed, but may include other steps or units not clearly listed or inherent to these processes, methods, products or devices.

[0047] Such as Figure 1-13As shown, a preferred embodiment of the present application is as follows:

[0048] A folding support leg, comprising:

[0049] A mounting base 100, which is adapted to be fixedly connected to the tabletop portion 600 of the folding table;

[0050] A stop member 200 rotatably arranged on the mounting base 100, the stop member 200 being rotatable in the horizontal direction between a first working position, a second working position and an unlocking position, the second working position being arranged between the first working position and the unlocking position, that is, in the process of the stop member 200 rotating from the unlocking position to the first working position, the stop member 200 will necessarily pass through the second working position. Preferably, as Figure 3-8 shown, the first working position, the second working position and the unlocking position are arranged in sequence in the clockwise direction;

[0051] And a support pipe fitting 300 rotatably arranged on the mounting base 100, the support pipe fitting 300 being rotatable in the vertical direction between a deployed position and a retracted position. When the support pipe fitting 300 is in the deployed position, the support pipe fitting 300 extends in the vertical direction. When the support pipe fitting 300 is in the retracted position, the support pipe fitting 300 extends in the horizontal direction. A first locking portion 330 and a second locking portion 340 are provided at one end of the support pipe fitting 300 connected to the mounting base 100. The stop member 200 is adapted to cooperate with the first locking portion 330 or the second locking portion 340 to limit the support pipe fitting 300 in the deployed position or the retracted position, thereby realizing the locking of the support pipe fitting 300.

[0052] Specifically, when the support pipe fitting 300 is in the deployed position, the stop member 200 can be rotated to the first working position to cooperate with the first locking portion 330 to limit the support pipe fitting 300 in the deployed position, so as to prevent the support pipe fitting 300 from rotating from the deployed position to the retracted position during the use of the folding table, resulting in the folding table tipping over; when the support pipe fitting 300 is in the retracted position, the stop member 200 can be rotated to the second working position to cooperate with the second locking portion 340 to limit the support pipe fitting 300 in the retracted position, so as to prevent the support pipe fitting 300 from rotating from the retracted position to the deployed position during the storage of the folding table, affecting the storage of the folding table.

[0053] Furthermore, the folding support leg further includes a reset member 400. The two ends of the reset member 400 are respectively connected to the stop member 200 and the mounting base 100. The reset member 400 is adapted to continuously apply a force to the stop member 200 to rotate it to the first working position, so that after the external force acting on the stop member 200 is removed, the stop member 200 can be rotated to the first working position to cooperate with the first locking portion 330 or rotated to the second working position to cooperate with the second locking portion 340, realizing automatic locking of the support pipe fitting 300. Specifically, when the user rotates the support pipe fitting 300 to the unfolded position, the position of the first locking portion 330 corresponds to the stop member 200, and the stop member 200 will be rotated to the first working position under the action of the reset member 400 to cooperate with the first locking portion 330, limiting the support pipe fitting 300 in the unfolded position; when the user rotates the support pipe fitting 300 to the retracted position, the position of the second locking portion 340 corresponds to the stop member 200, and the stop member 200 will automatically rotate to the second working position under the action of the reset member 400 to cooperate with the second locking portion 340, limiting the support pipe fitting 300 in the retracted position, without the need for the user to manually operate to lock the support pipe fitting 300.

[0054] It is worth mentioning that the reset member 400 can be implemented as any material having elastic potential energy and capable of pushing the stop member 200 to the first working position after the external force acting on the stop member 200 is removed.

[0055] Such as Figure 3-9As shown, in some preferred embodiments, the stop member 200 includes a central shaft 210. An eccentric bump 220 for cooperating with the first locking portion 330 and the second locking portion 340 is provided in the middle of the central shaft 210. The lower end of the central shaft 210 is rotatably connected to the mounting base 100. A handle 230 is connected to the upper end of the central shaft 210. A user can rotate the stop member 200 relative to the mounting base 100 between a first working position, a second working position, and an unlocking position by pulling the handle 230. The reset member 400 is implemented as a torsion spring. The torsion spring is sleeved on the lower end of the central shaft 210. One end of the torsion spring is connected to the mounting base 100, and the other end of the torsion spring is disposed on the side end surface of the eccentric bump 220. When the stop member 200 is in the first working position, the reset member 400 is not twisted and the reset member 400 does not apply a force to the stop member 200. When the user pulls the handle 230 to rotate the stop member 200 to the second working position, the reset member 400 is twisted and deformed, and the reset member 400 is adapted to apply a force to the stop member 200 to drive the stop member 200 to rotate to the first working position. When the user pulls the handle 230 to rotate the stop member 200 to the unlocking position, the reset member 400 is further twisted and deformed, and the reset member 400 is adapted to apply a force to the stop member 200 to drive the stop member 200 to rotate to the first working position. When the external force applied to the stop member 200 is removed, the reset member 400 can recover the deformation to drive the stop member 200 to rotate to the first working position.

[0056] Since a reset member 400 is provided between the stop member 200 and the mounting base 100, a certain magnitude of force needs to be applied to the stop member 200 to rotate the stop member 200 from the first working position or the second working position to the unlocking position. Thus, when the stop member 200 locks the support pipe fitting 300, the stop member 200 will not easily rotate from the first working position or the second working position to the unlocking position, ensuring the locking strength of the stop member 200 on the support pipe fitting 300 and avoiding the folding table from tipping over due to insufficient locking strength.

[0057] Furthermore, the first locking portion 330 is implemented as a locking groove, and the second locking portion 340 is implemented as a locking end face. The first locking portion 330 and the second locking portion 340 are provided at one end where the support pipe fitting 300 is connected to the mounting base 100. Specifically, the first locking portion 330 is provided on the side surface of the end of the support pipe fitting 300, and the second locking portion 340 is provided on the top surface of the end of the support pipe fitting 300. Then, when the support pipe fitting 300 rotates to the deployed position, the first locking portion 330 aligns with the eccentric convex block 220, and the stop member 200 is adapted to rotate to the first working position, so that the eccentric convex block 220 is embedded in the first locking portion 330, that is, the eccentric convex block 220 is engaged with the locking groove to restrict the rotation of the support pipe fitting 300, realizing the locking of the support pipe fitting 300; when the support pipe fitting 300 rotates to the retracted position, the second locking portion 340 aligns with the eccentric convex block 220, and the stop member 200 is adapted to rotate to the second working position, so that the eccentric convex block 220 cooperates with the second locking portion 340, that is, the side end face of the eccentric convex block 220 fits with the locking end face to restrict the rotation of the support pipe fitting 300, realizing the locking of the support pipe fitting 300.

[0058] When the user wants to rotate the support pipe fitting 300, only need to pull the handle 230 to rotate the stop member 200 to the unlocking position to release the locking of the support pipe fitting 300; when the support pipe fitting 300 rotates to the deployed position or the retracted position, the user releases the handle 230 and the stop member 200 will automatically lock the support pipe fitting 300, locking the support in the deployed position or the retracted position. The whole locking and unlocking operations are simple and convenient, and the support pipe fitting 300 is firm and reliable after locking.

[0059] In some preferred embodiments, in order to improve the applicability of the folding support leg, the support pipe fitting 300 is also arranged as a telescopic pipe structure. Specifically, as Figure 11-12 shown, the support pipe fitting 300 includes an outer pipe 310 and an inner pipe 320. The inner pipe 320 is slidably sleeved inside the outer pipe 310. A locking assembly 500 is provided on the outer pipe 310 and the inner pipe 320. The locking assembly 500 is adapted to fasten the inner pipe 320 at any position inside the outer pipe 310. Then, the user can steplessly adjust the inner pipe 320 within a certain range and freely adjust the length of the support pipe fitting 300.

[0060] Further, the locking assembly 500 includes a fixing member 510 and a rotating member 520. The fixing member 510 includes a connecting end 511 and a locking end 512. The connecting end 511 is fixedly connected to the outer tube 310. The locking end 512 is sleeved on the outer side wall of the inner tube 320. The locking end 512 includes a plurality of locking blocks. The locking blocks are arranged in a surrounding manner, and one end of each locking block is thick and the other end is thin. Thus, the locking end 512 is conical. An external thread is also provided on the outer side wall of the connecting end 511. An internal thread is provided on the inner side wall of the rotating member 520. The rotating member 520 is threadedly connected to the fixing member 510. The rotating member 520 can rotate relative to the fixing member 510 and push or release the locking end 512. When the rotating member 520 pushes the locking end 512, the rotating member 520 applies a force to each locking block, and each locking block clamps the inner tube 320 inwardly, fastening the inner tube 320 inside the outer tube 310. When the rotating member 520 releases the locking end 512, the force exerted by the rotating member 520 on each locking block is removed, and each locking block releases the inner tube 320. The inner tube 320 can slide and adjust inside the outer tube 310.

[0061] As Figure 13 shown, a spherical foot pad 350 is further provided at the end of the inner tube 320. A plurality of anti-slip grooves 351 are formed on the spherical foot pad 350. The spherical foot pad 350 can facilitate the support foot to adapt to the placement plane at any angle, improving the applicability of the self-locking folding support foot.

[0062] As Figure 14-19 shown, the present application further provides a folding table. The folding table includes four of the above-mentioned folding support legs and a table top portion 600. The folding support legs are arranged at the four corners of the table top portion 600. The table top portion 600 includes two folding table boards 610. The two folding table boards 610 are hinged through a connecting assembly 700. When the folding table is unfolded for use, the two folding table boards 610 can be laid flat and unfolded. When the folding table is folded and stored, the two folding table boards 610 can be folded up and down.

[0063] The connecting assembly 700 specifically includes a first connecting seat 710 and a second connecting seat 720 that are hinged to each other. The first connecting seat 710 and the second connecting seat 720 are respectively arranged on the two folding table boards 610. A limiting rod 740 is also hinged on the first connecting seat 710. When the two folding table boards 610 are laid flat and unfolded, a limiting groove 730 is formed between the first connecting seat 710 and the second connecting seat 720. The limiting rod 740 can be inserted into the limiting groove 730 and simultaneously abut against the two folding table boards 610, thereby preventing the folding table boards 610 from flipping and folding, so that the table top portion 600 can maintain the unfolded state.

[0064] In addition, as Figure 20As shown, a tension spring can also be provided between the first connecting seat 710 and the second connecting seat 720 to keep the table top portion 600 in the unfolded state. When the two folding table boards 610 are laid out flat, the tension spring is stretched, so that the two folding table boards 610 are kept in the flat unfolded state when the external force does not exceed a preset value.

[0065] In summary, when the user unfolds the folding table, after the two folding table boards 610 are unfolded, the limiting rod 740 is inserted into the limiting groove 730, and the support pipe fitting 300 is locked in the unfolded position by turning the stop member 200 with the handle 230. The whole operation process does not require external tools such as a screwdriver, which is simple and labor-saving.

[0066] The foregoing has described the basic principles, main features and advantages of the present application. Those skilled in the art of this industry should understand that the present application is not limited by the above embodiments. What is described in the above embodiments and the specification is only the principle of the present application. Without departing from the spirit and scope of the present application, the present application will have various changes and improvements, and these changes and improvements all fall within the scope of the present application claimed.
