Patent number: 9345317Abstract: 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.Type: GrantFiled: December 5, 2014Date of Patent: May 24, 2016Inventor: Mei-Fang Chang

Patent number: 8561552Abstract: 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.Type: GrantFiled: January 7, 2010Date of Patent: October 22, 2013Inventor: Mei-Fang Chang

Patent number: 6131992Abstract: 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.Type: GrantFiled: June 1, 1999Date of Patent: October 17, 2000Inventor: Mei-Fang Chang

Patent number: 5957061Abstract: 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.Type: GrantFiled: May 29, 1998Date of Patent: September 28, 1999Inventor: Mei-Fang Chang
