Technical Field

[0001] This invention relates to the field of table and chair technology, specifically to a table and chair leg connection structure and a table and chair. Background Technology

[0002] Tables and chairs are common pieces of furniture, typically featuring a flat surface and a support structure. They can be used in various settings, such as homes, offices, and dining rooms. Tables and chairs are essential pieces of furniture in daily life, providing a convenient surface for various activities such as working, studying, and dining, while also decorating and beautifying interior spaces. Currently, in existing tables and chairs, the legs and tabletop are usually fixed together, as are the legs and seat of chairs. This results in them taking up a lot of space when not in use and needing to be stored, or being extremely inconvenient to move. Traditional mortise and tenon joints offer strong stability and good load-bearing capacity, but the tenons are prone to loosening due to the expansion and contraction of wood with temperature changes, leading to extremely high costs for mass production and after-sales maintenance.

[0003] This case arose in order to resolve the aforementioned issues. Summary of the Invention

[0004] The purpose of this invention is to provide a table and chair leg connection structure and a table and chair to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, the present invention provides the following technical solution: a table and chair leg connection structure and a table and chair, including a tabletop and table legs. The side of the tabletop is provided with equally spaced upper and lower grooves, which correspond one-to-one. A baffle is provided between the upper and lower grooves.

[0007] Preferably, after the baffle and the slot are inserted, the horizontal plate is located in the upper slot and there is a gap between the horizontal plate and the upper slot. A limiting member is inserted into the gap. The limiting member includes a flat plate. Limiting plates are provided on both sides of the rear end of the flat plate and rotating plates are provided on both sides of the front end of the flat plate. The rotating plate (11) is rotatably connected to the bottom surface on both sides of the flat plate. The rotating shaft of the rotating plate is located on the side close to the limiting plate. An insertion port is provided on the outer side of the rotating plate.

[0008] Preferably, clamping components are symmetrically arranged on both sides of the upper groove. The clamping components include a sliding groove, and a spring is provided at the bottom of the sliding groove. One end of the spring is connected to the bottom of the sliding groove, and the other end is connected to a sliding block. One end of the sliding block is connected to the spring, and the other end is inclined.

[0009] Preferably, the outer side of the sliding groove is provided with a translation groove, the side of the sliding block is connected with a crossbar, the crossbar is slidably connected to the translation groove, one end of the crossbar is fixedly connected to the side of the sliding block, and the other end extends out from the side of the table and is connected to a lever.

[0015] The present invention will be further described in detail below with reference to the accompanying drawings and embodiments.

[0016] This invention provides a table and chair leg connection structure and a table and chair, such as... Figure 1-5As shown, the table includes a tabletop 1 and table legs 2. The side of the tabletop 1 has equally spaced upper slots 3 and lower slots 4, which correspond one-to-one. A baffle 5 is provided between the upper slots 3 and lower slots 4. The top of the table legs 2 has a slot 6, and the baffle 5 and the slot 6 are inserted into each other. The arrangement between the slot 6 and the baffle 5 allows the tabletop to be supported by the table legs.

[0017] Reference Appendix Figure 4 The table leg 2 has a vertical plate 7 on its outer top, and a horizontal plate 8 on its top. A groove 6 is formed between the horizontal plate 8 and the top surface of the table leg 2. The length and width of the horizontal plate 8 are smaller than the length and width of the upper groove 3, and the width of the vertical plate 7 is smaller than the width of the upper groove 3 and the lower groove 4. This allows the table leg to be inserted into the baffle 5 and the groove 6 from the outside of the tabletop.

[0018] After the baffle 5 and the slot 6 are inserted, the horizontal plate 8 is located inside the upper slot 3, and there is a gap between the horizontal plate 8 and the upper slot 3. A limiting component is inserted into the gap. The limiting component includes a flat plate 9, with limiting plates 10 on both sides of the rear end of the flat plate 9 and rotating plates 11 on both sides of the front end of the flat plate 9. The rotating plates 11 are rotatably connected to the bottom surfaces on both sides of the flat plate 9. The rotation axis of the rotating plates 11 is located on the side close to the limiting plates 11, and the outer side of the rotating plates 11 has an insertion port 111. It should be noted that the table legs are made of wood, while the tabletop and the limiting component are made of other materials, not wood. The gap is left to accommodate the significant thermal expansion and contraction of the wooden table legs. After the limiting component is inserted into the gap, it forms a fixing effect similar to a mortise and tenon structure. On the one hand, it fills the gap to prevent fingers from being pinched, and on the other hand, it plays a role in auxiliary fixing. At the same time, the limiting component can also be aesthetically designed.

[0019] Reference Appendix Figure 4-5 A locking assembly is symmetrically arranged on both sides of the upper slot 3. The locking assembly includes a sliding groove 12, and a spring 13 is provided at the bottom of the sliding groove 12. One end of the spring 13 is connected to the bottom of the sliding groove 12, and the other end is connected to a sliding insert 14. One end of the sliding insert 14 is connected to the spring 13, and the other end is inclined. When the limiting member is inserted, the rotating plate slides down along the inclined surface, the spring is compressed, and after full insertion, one end of the sliding insert 14 abuts into the insertion port 111.

[0020] Reference Appendix Figure 5 The outer side of the sliding groove 12 is provided with a translation groove 17. A crossbar 15 is connected to the side of the sliding block 14. The crossbar 15 is slidably connected to the translation groove 17. One end of the crossbar 15 is fixedly connected to the side of the sliding block 14, and the other end extends out from the side of the table and is connected to a lever 16. When disassembly is required, the lever 16 is pushed to both sides, and the limiting member can be pushed upward to achieve disassembly.

[0021] It should be noted that the inner side of the rotating plate 11 is wavy, and a rubber pad is provided on the wavy shape. When the sliding block is pressed against the rotating plate, the wavy shape on the inner side of the rotating plate presses against both sides of the horizontal plate 8. The length of the upper groove 3 is greater than the length of the lower groove 4, making the tabletop more stable.

[0022] It should be noted that the tabletop and table legs can be replaced with chair seats and chair legs, with the same structural settings.

[0023] This invention discloses a table and chair leg connection structure and a table and chair. The tabletop, table legs and limiting components are arranged to form a mortise and tenon-like structure to achieve mutual locking and limiting. While facilitating disassembly, a rotating plate is set in the limiting component. The rotating plate is dynamically pressed by a sliding block to avoid the loosening problem caused by the thermal expansion and contraction of wood.

[0024] The above are merely specific embodiments of the present invention, but the scope of protection of the present invention is not limited thereto. The scope of protection of the present invention should be determined by the scope of the claims.
