Description

Technical Field

[0001] This utility model relates to the field of furniture technology, and in particular to an integrated dining table and chair. Background Technology

[0002] As basic household furniture, the structure of dining tables and chairs directly affects space utilization and environmental hygiene maintenance efficiency. Traditional separate dining tables and chairs consist of an independent table and several chairs, with no fixed connection between the chairs and the table. After use, they need to be manually put back in place. In public places such as school cafeterias and fast food restaurants, frequent movement causes confusion for pedestrians and may even lead to tripping accidents. Therefore, integrated dining tables and chairs are now used, which connect the table and chairs into a unified whole. This structure not only avoids the space waste caused by separate tables and chairs, but also enhances the overall stability and aesthetics to a certain extent.

[0003] However, currently used integrated dining tables and chairs generally employ traditional support legs. While these provide necessary support for the seats and ensure user safety and comfort, they present several problems in actual use: First, during daily cleaning, the presence of these support legs greatly inconveniences cleaners, creating narrow spaces and dead zones under the seats. Cleaners using brooms, mops, and other cleaning tools are often obstructed by these legs, making it difficult to thoroughly clean these corners. This allows dust, food residue, and other grime to accumulate in these areas, affecting hygiene and potentially breeding bacteria, posing a threat to user health. Second, when using robotic vacuum cleaners, the support legs cause them to frequently encounter obstacle avoidance problems. Their sensors constantly detect the presence of the support legs, causing the robot to frequently change its path, sometimes even becoming trapped between the legs. This not only prolongs cleaning time and reduces efficiency but also fails to ensure a comprehensive and effective cleaning of the area under the tables and chairs, failing to meet users' expectations for efficient and convenient cleaning. Summary of the Invention

[0004] In view of the shortcomings of the prior art, the technical problem to be solved by this patent application is how to provide an integrated dining table and chair that can suspend the support legs when the chair is not in use, making it easy to clean and highly efficient.

[0005] To solve the above-mentioned technical problems, the present invention adopts the following technical solution:

[0006] An integrated dining table and chair set includes a table body and four seats symmetrically arranged on both sides of the table body. The table body includes a table frame and a tabletop fixedly installed on the upper part of the table frame. The tabletop is horizontally arranged. Two connecting rods are fixedly installed outward from the middle of each side of the table frame. The ends of the two connecting rods on the same side away from the table frame are fixedly connected to support rods. The support rods are horizontally arranged and located outside the tabletop. Both ends of the support rods are fixedly installed with rings. The lower end of each seat is fixedly connected to a support leg through a connecting structure. The support leg is cylindrical and slides with the inner ring surface of the ring. The lower end of the support leg is fixed with a support foot. A lifting support structure is provided between the lower end of the ring and the support leg. A positioning locking structure is provided between the upper end of the ring and the support leg.

[0007] This design integrates the table and four chairs into a single structure, improving overall integrity and avoiding the space wastage that would result from separate tables and chairs. Support legs are connected to the seat base via a connecting structure. When the chair is in use, a locking mechanism locks its orientation, preventing rotation during use. The support legs contact the ground, providing support and stability. When the chair is not in use, it can be lifted for easy cleaning, allowing the support legs to slide upwards along the ring. The lifting support structure then supports the chair, with the legs spaced apart from the ground for easy cleaning. With this integrated dining table and chair design, only the table frame contacts the ground, significantly improving floor cleaning convenience compared to the previous design where the support legs were in direct contact. Typically, for ease of use, the distance between the support legs and the ground is greater than 15 cm when the lifting support structure supports the chair, meaning the support legs can slide upwards at least 15 cm relative to the ring to facilitate cleaning the space beneath them. The support body is cylindrical, allowing it to slide and rotate relative to the ring.

[0008] Preferably, the lifting support structure includes a bracket and a lower fixing sleeve. The bracket is positioned below the ring and is fixedly connected to the ring via a support block. The lower fixing sleeve is fixedly installed on the lower part of the support leg. A lower plate is coaxially fixed to the upper end of the lower fixing sleeve. Two symmetrically arranged pins are fixedly installed on the lower plate. A cylinder is coaxially fixed to the upper end of each pin, and the diameter of the cylinder is larger than the diameter of the pin. The bracket has two centrally symmetrically arranged arc-shaped waist-shaped holes, each arc-shaped waist-shaped hole including a large-diameter section and a small-diameter section. The diameter of the cylinder is smaller than the diameter of the large-diameter section but larger than the diameter of the small-diameter section. The diameter of the pin is smaller than the diameter of the small-diameter section.

[0009] In this configuration, when the seat is in use, the support legs are in contact with the ground, and the lower fixing sleeve is positioned away from the bracket. When the seat is not in use, holding the seat and moving it upwards allows the cylinder to pass through the larger diameter section of the arc-shaped hole. Then, rotating the seat causes the cylinder to rotate to the smaller diameter section of the arc-shaped hole. Since the cylinder's diameter is smaller than the larger diameter section but larger than the smaller diameter section, the bracket can support the cylinder, thus supporting the seat and lifting the support legs off the ground. The seat is made of lightweight plastic and is easy to lift. A reverse rotation unlocks the seat, facilitating the lowering of the support legs.

[0010] Preferably, the orientation locking structure includes an upper fixing sleeve fixedly installed on the upper part of the support leg, an upper plate coaxially fixed at the lower end of the upper fixing sleeve, and four positioning pins fixedly installed downward on the upper plate. The four positioning pins are located on a circle coaxially arranged with the support leg, and the circle is provided with four positioning holes that can be inserted and cooperate with the positioning pins.

[0011] In this way, when the chair is needed, the positioning pin is inserted into the positioning hole to prevent the support leg from rotating randomly during use, ensuring that the chair is fixed in position, such as facing the table, avoiding the user's sitting posture from shifting or the chair from shaking, thus improving safety and comfort.

[0012] Preferably, the lower end of the positioning pin is hemispherical.

[0013] In this way, the hemispherical design reduces the frictional resistance and alignment difficulty when the positioning pin is inserted into the positioning hole, making it easier for users to quickly complete the locking operation and improving the convenience of adjustment.

[0014] Preferably, the connection structure includes a connecting frame integrally formed with the seat and a connecting plate fixedly installed on the upper end of the support leg. The connecting frame includes a plurality of connecting blocks fixedly formed with the seat body and a connecting seat fixedly formed with the connecting blocks. The connecting seat is provided with a plurality of threaded holes. The connecting plate is provided with a relief hole opposite to the threaded hole. The connecting bolt passes through the relief hole and connects with the threaded hole of the connecting seat.

[0015] In this way, the connection structure ensures that the seat and support legs are firmly and reliably connected, preventing loosening during use; the bolt connection method facilitates assembly, disassembly and maintenance, reducing production and after-sales costs.

[0016] In summary, this integrated dining table and chair set offers the advantages of allowing the support legs to be suspended when the chairs are not in use, making it easy to clean and highly efficient. Attached Figure Description

[0026] like Figure 1-8 As shown, an integrated dining table and chair set includes a table body and four seats 1. The four seats are symmetrically arranged on both sides of the table body. The table body includes a table frame 11 and a tabletop 12 fixedly installed on the upper part of the table frame. The tabletop is horizontally arranged. Two connecting rods 13 are fixedly installed outward from the middle of both sides of the table frame. The ends of the two connecting rods on the same side away from the table frame are fixedly connected to support rods 14. The support rods are horizontally arranged and located on the outside of the tabletop. Both ends of the support rods are fixedly installed with rings 15. The lower end of the seats is fixedly connected to support legs 16 through a connecting structure. The support legs are cylindrical and slide in contact with the inner ring surface of the rings. The lower end of the support legs is fixed with support feet 17. A lifting support structure is provided between the lower end of the rings and the support legs. A positioning locking structure is provided between the upper end of the rings and the support legs.

[0027] This design integrates the table and four chairs into a single structure, improving overall integrity and avoiding the space wastage that would result from separate tables and chairs. Support legs are connected to the seat base via a connecting structure. When the chair is in use, a locking mechanism locks its orientation, preventing rotation during use. The support legs contact the ground, providing support and stability. When the chair is not in use, it can be lifted for easy cleaning, allowing the support legs to slide upwards along the ring. The lifting support structure then supports the chair, with the legs spaced apart from the ground for easy cleaning. With this integrated dining table and chair design, only the table frame contacts the ground, significantly improving floor cleaning convenience compared to the previous design where the support legs were in direct contact. Typically, for ease of use, the distance between the support legs and the ground is greater than 15 cm when the lifting support structure supports the chair, meaning the support legs can slide upwards at least 15 cm relative to the ring to facilitate cleaning the space beneath them. The support body is cylindrical, allowing it to slide and rotate relative to the ring.

[0028] In implementation, the lifting support structure includes a bracket 18 and a lower fixing sleeve 19. The bracket is located below the ring and is fixedly connected to the ring via a support block 2. The lower fixing sleeve is fixedly installed on the lower part of the support leg. A lower plate 21 is coaxially fixed to the upper end of the lower fixing sleeve. Two symmetrically arranged pins 22 are fixedly installed on the lower plate. A cylinder 23 is coaxially fixed to the upper end of the pins. The diameter of the cylinder is larger than the diameter of the pin. The bracket is provided with two centrally symmetrical arc-shaped waist-shaped holes 24. The arc-shaped waist-shaped holes include a large-diameter section and a small-diameter section. The diameter of the cylinder is smaller than the diameter of the large-diameter section but larger than the diameter of the small-diameter section. The diameter of the pin is smaller than the diameter of the small-diameter section.

[0029] In this configuration, when the seat is in use, the support legs are in contact with the ground, and the lower fixing sleeve is positioned away from the bracket. When the seat is not in use, holding the seat and moving it upwards allows the cylinder to pass through the larger diameter section of the arc-shaped hole. Then, rotating the seat causes the cylinder to rotate to the smaller diameter section of the arc-shaped hole. Since the cylinder's diameter is smaller than the larger diameter section but larger than the smaller diameter section, the bracket can support the cylinder, thus supporting the seat and lifting the support legs off the ground. The seat is made of lightweight plastic and is easy to lift. A reverse rotation unlocks the seat, facilitating the lowering of the support legs.

[0030] In implementation, the orientation locking structure includes an upper fixing sleeve 25 fixedly installed on the upper part of the support leg, an upper plate 26 coaxially fixed at the lower end of the upper fixing sleeve, and four positioning pins 27 fixedly installed downward on the upper plate. The four positioning pins are located on a circle coaxially arranged with the support leg, and the circle is provided with four positioning holes 28 that can be inserted and cooperate with the positioning pins.

[0031] In this way, when the chair is needed, the positioning pin is inserted into the positioning hole to prevent the support leg from rotating randomly during use, ensuring that the chair is fixed in position, such as facing the table, avoiding the user's sitting posture from shifting or the chair from shaking, thus improving safety and comfort.

[0032] In practice, the lower end of the positioning pin is hemispherical.

[0033] In this way, the hemispherical design reduces the frictional resistance and alignment difficulty when the positioning pin is inserted into the positioning hole, making it easier for users to quickly complete the locking operation and improving the convenience of adjustment.

[0034] In implementation, the connection structure includes a connecting frame integrally formed with the seat and a connecting plate 29 fixedly installed on the upper end of the support leg. The connecting frame includes a plurality of connecting blocks 3 fixedly formed with the seat body and a connecting seat 31 fixedly formed with the connecting blocks. The connecting seat is provided with a plurality of threaded holes 32. The connecting plate is provided with relief holes 33 opposite to the threaded holes. The connecting bolt passes through the relief holes and connects with the threaded holes of the connecting seat.

[0035] In this way, the connection structure ensures that the seat and support legs are firmly and reliably connected, preventing loosening during use; the bolt connection method facilitates assembly, disassembly and maintenance, reducing production and after-sales costs.

[0036] Finally, it should be noted that those skilled in the art can make various modifications and variations to this utility model without departing from its spirit and scope. Therefore, if these modifications and variations fall within the scope of the claims and their equivalents, this utility model also intends to include these modifications and variations.
