  • Publication number: 20170181537
    Abstract: An anti-folding leg assembly for a tabletop includes a leg frame for pivotally coupling at a bottom side of the tabletop to pivotally move between a folded position and an unfolded position, and an anti-folding arrangement including a table support having has a table coupling end adapted for pivotally coupling at the bottom side of the tabletop, and a leg support having a leg coupling end pivotally coupled at the leg frame. A pivot point is defined at a pivot connection between the table support and the leg support, and a centerline is defined between the table coupling end of the table support and the leg in coupling end of the leg support when the leg frame is moved in the unfolded position, wherein the pivot point is located below the centerline when the leg frame is moved in the unfolded position.

  • Patent number: 9345317
    Abstract: A foldable table includes a tabletop having a top side and a bottom side, a leg frame, and a stacking arrangement which includes a stackable rim integrally and downwardly extended from the top side of the tabletop to a position that a bottom edge of the stackable rim is downwardly extended below the bottom side of the tabletop, wherein a stacking area is defined within the bottom edge of the stackable rim that the stacking area is larger than a top area of the top side of the tabletop. Therefore, when two or more foldable tables are stacked together, the top side of the foldable table is received within the stacking area of another foldable table to substantially retain the two foldable tabletops in position and avoid a lateral relative movement between the foldable tables.

  • Patent number: 8561552
    Abstract: A foldable table includes a table top, two leg frames foldably coupling with a bottom side of the table top, and a torsion resistance frame including two longitudinal side frames parallelly provided along two longitudinal side portions of the table top respectively, and two lateral side reinforcing members laterally extended between the longitudinal side frames at two lateral side portions of the table top to form an anti-torsion frame for encircling with a peripheral portion of the table top. The torsion resistance frame is integrated with the bottom side of the table top, making it a one-piece table frame structure with increased rigidity at its maximum level, resistance to the external force of torsion and distortion. The table, having the maximum utility with minimum materials, has increased durability, comfort in usage and convenience for transportation and has lowered energy consumption in the manufacture of household furniture.

  • Patent number: 6131992
    Abstract: A foldable chair supported by rear supporting legs is disclosed. The rear supporting legs are directly connected to a seat. A positioning structure for resisting against the seat is installed at the fulcrum of the front supporting leg. When the seat is expanded, the fulcrum of each supporting leg practically suffers force from the seat, thus the force is distributed uniformly to the four legs. In using, even the user leans against the chair back, the chair may be still steady. The chair back has a cambered surface. After being folding, the volume occupied does not increase. Therefore, the packaging material will be saved.

  • Patent number: 5957061
    Abstract: A banquet table including a table surface, upper frames fixedly installed on the bottom side of the table surface, and leg frames which are rotatably connected to the upper frames so as to allow the leg frames to be folded inward and toward the bottom side of the table surface. The table surface can also be formed by two sections for folding. The two-section banquet table also includes a pair of hinges for connecting the upper frames on each table section. The hinges are designed to include two facing pressure resisting sections so that when the table is extended, the pressure of the table is applied on the pressure resisting sections, instead of the connecting pin shafts.
