Description

Technical Field

[0001] The utility model relates to the field of tables and chairs, in particular to foldable tables and chairs. Background Art

[0002] In daily life, tables and chairs are essential furniture for learning, working, resting, and dining. Their design and functionality directly impact user comfort and experience. Traditional table and chair designs often focus on stability and load-bearing capacity, but lack space utilization and portability. This is particularly true in space-constrained settings, such as small homes, offices, classrooms, and outdoor activities. Traditional tables and chairs are bulky and take up a lot of space, making them difficult to meet users' demands for efficient space utilization.

[0003] As lifestyles change and living environments diversify, higher demands are being placed on tables and chairs for portability, versatility, and spatial adaptability. Against this backdrop, folding tables and chairs have emerged and are becoming a popular furniture design trend. Their ingenious design allows them to fold up when not in use, significantly reducing space, making them easier to store and carry, and lowering transportation costs.

[0004] The design principles of folding tables and chairs vary, but the fundamental idea is to connect the various parts of the table or chair through some form of connector or folding mechanism, allowing them to fold and unfold within a certain range. The design of these connectors and folding mechanisms directly affects the stability, durability, and ease of use of the folding table and chair. For example, some folding tables and chairs use hinges made of metal or plastic as connectors, which rotate to achieve folding and unfolding; others use slide rails, slots, and other structures to achieve folding through sliding or snapping.

[0005] Despite significant advancements in design and functionality, folding tables and chairs still face some challenges. Some folding tables and chairs are complex and inconvenient to operate. Table legs are often designed with a two-stage folding mechanism to facilitate folding. This means the legs fold once and then fold upwards to align with or align with the tabletop. However, this method requires two operations to fold and unfold, making it cumbersome. Utility Model Content

DETAILED DESCRIPTION

[0029] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments.

[0030] See also Figure 1-9 , an embodiment provided by the utility model:

[0031] 1. Folding Table Design:

[0032] The foldable table 1 comprises a table top 2, and a storage drawer 3 is welded and fixed in the middle of the lower end of the table top 2 for storing items. Users can store items neatly under the table, which saves space and is convenient for access.

[0033] Folding legs 4 are installed on both sides of the front and rear ends of the lower end of the tabletop 2. The two folding legs 4 on each side are staggered. This staggered arrangement of the folding legs makes the table more stable when unfolded and prevents it from tipping over. The folding legs 4 include a first fixed base 5, a limit sliding rod 6, and a fixed upright plate 7. The first fixed base 5 and the fixed upright plate 7 are respectively fixed to the front and rear ends of the lower end of the tabletop 2. The limit sliding rod 6 is fixed between the first fixed base 5 and the fixed upright plate 7 to limit the sliding range of the rotating plate 16.

[0034] The folding table leg 4 also includes a rotating leg 8, which has a sliding groove 9 running through it. The groove runs through the rotating leg 8 in three directions: forward, backward and downward, so that the retracting leg 11 can slide freely therein. The sliding groove running through in three directions makes the retracting leg 11 more flexible and unrestricted when unfolding and folding.

[0035] The retractable leg 11 includes a leg body 12, which is located in the through-sliding groove 9 and extends downward. An upper fixed block 13 is fixed to the upper end of the leg body 12, and the upper fixed block 13 is also located in the through-sliding groove 9. A second fixed seat 15 is fixed to the inner end of the upper fixed block 13, and a rotating plate 16 is rotatably connected to the second fixed seat 15. The other end of the rotating plate 16 extends into the third fixed seat 18 and is rotatably connected to the third fixed seat 18. A sliding block 17 is integrally connected to one end of the third fixed seat 18, and the sliding block 17 is located outside the limiting sliding rod 6 and is slidably connected to the limiting sliding rod 6. The cooperation between the rotating plate 16 and the sliding block 17 allows the retractable leg 11 to slide smoothly in the through-sliding groove 9 of the rotating leg 8, and the rotating leg 8 can rotate to realize the unfolding and folding of the table.

[0036] Limiting structure:

[0037] A limit rod 10 is fixed within the sliding slot 9 of the pivoting leg 8. A limit slot 14 is defined in the center of the leg body 12 and the upper fixing block 13. This slot 14 mates with the limit rod 10. The leg body 12 is connected to the pivoting leg 8 through the limited sliding relationship between the slot 14 and the limit rod 10. The cooperation between the slot 14 and the limit rod 10 ensures that the retractable leg 11 is more stable during sliding and is less likely to deviate from the track.

[0038] Fixed structure:

[0039] The rotating plate 16 and the second fixing seat 15 and the third fixing seat 18 are all locked and fixed by fixing bolts 19, so that the rotating plate can be firmly fixed at a designated position after being unfolded and is not easy to loosen.

[0040] 2. Folding Chair Design:

[0041] A folding chair 20 is provided at the front end of the folding table 1. The folding chair 20 includes a seat 21, which is convenient for the user to use the table and the chair at the same time. The design of the folding chair 20 enables the user to easily find a seat when using the table, thereby improving the convenience of use.

[0042] A fourth mounting bracket 22 is welded to each side of the front end of the lower end of the storage drawer 3. A pivoting folding plate 23 is pivotally connected to the fourth mounting bracket 22. The other end of the pivoting folding plate 23 extends to the rear end of the side of the seat 21 and pivotally connects to the seat 21. When the folding table and chair are folded, the pivoting plate 23 naturally rotates with it, allowing the folding table 1 and folding chair 20 to be unfolded and placed, or folded and stored, at a predetermined distance. The design of the pivoting folding plate 23 provides greater flexibility and convenience when folding and unfolding the table and chair, while maintaining the relative position between them.

[0043] Fifth mounting brackets 24 are welded to the front and rear ends of the lower end of the seat 21, with two fifth mounting brackets 24 arranged alternately on each side. Legs 25 are pivotally connected to the fifth mounting brackets 24 and secured to the fifth mounting brackets 24 with bolts. The user can push the legs 25 outward to align them perpendicularly with the seat 21 as needed, and then secure them with bolts. The staggered arrangement of the legs 25 ensures a more stable and secure fit when the chair is deployed.

[0044] Working principle: When unfolded, the rotating plate 16 is pushed toward the outward end. Through the limited sliding relationship between the sliding block 17 and the limited sliding rod 6, the rotating connection relationship between the rotating plate 16 itself and the third fixed seat 18 at the lower end of the sliding block 17, the rotating connection relationship between the rotating plate 16 itself and the second fixed seat 15 at the inner end of the upper fixed block 13, and the limited sliding relationship between the upper fixed block 13 and the rotating leg 8 inside the rotating leg 8, the rotating plate 16 is transformed from a horizontal state to a vertical rotation, pushing the rotating leg 8 to rotate outward, and at the same time pushing the retracting leg 11 to slide outward along the rotating leg 8 until the rotating leg 8 and the retracting leg 11 are perpendicular to the table top 2. The two ends of the rotating plate 16 are locked with the fixing bolts 19. When the position of the rotating plate 16 is fixed, the rotating leg 8 and the retracting leg 11 are fixed.

[0045] The chair legs 25 are pushed outward so that they are perpendicular to the seat 21 , and are then locked with bolts to maintain the position of the chair legs 25 .

[0046] The foldable table and chair are rotated as a whole, the legs 12 and the chair legs 25 are in contact with the ground, and the rotating folding plate 23 naturally follows the rotation so that the foldable table 1 and the foldable chair 20 are unfolded and placed at a preset distance.

[0047] To collapse, the entire foldable table and chair rotates, folding the seat 21 backward toward the storage drawer 3 so that it partially aligns with the lower end of the drawer 3. Loosening the bolts causes the legs 25 to fold. Loosening the fixing bolts 19 pushes the pivoting plate 16 inward, causing the retractable legs 11 to slide inward along the pivoting legs 8, which simultaneously rotate inward. After folding, multiple tables and chairs can be stacked one on top of the other.

[0048] It will be apparent to those skilled in the art that the present invention is not limited to the details of the exemplary embodiments described above and that the present invention can be implemented in other specific forms without departing from the spirit or essential characteristics of the present invention. Therefore, the embodiments should be considered in all respects as illustrative and non-restrictive, and the scope of the present invention is defined by the appended claims, not the foregoing description, and all variations within the meaning and range of equivalents of the claims are intended to be encompassed within the present invention. Any reference sign in a claim should not be construed as limiting the claim to which it relates.
