  • Patent number: 6348005
    Abstract: A swing assembly includes a support frame unit with two side legs and a horizontal bar interconnecting the side legs, a seat unit, and linking units for suspending the seat unit. The seat unit includes a rectangular base frame connected to lower ends of the linking unit. The base frame includes a pair of lateral frame sections, and front and rear rods interconnecting the lateral frame sections. A seat frame has a front end portion resting on the front rod, and a rear end portion connected pivotally to a front end portion of a backrest frame, which is pivoted to the lateral frame sections of the base frame so as to be pivotable relative to the seat frame and the base frame for moving between a flat position, in which a rear end portion of the backrest frame rests on the rear rod, and an inclined position, in which the rear end portion of the backrest frame is raised to be disposed above the rear rod. A backrest support has an upper end pivoted to an intermediate portion of the backrest frame.

  • Patent number: 6254177
    Abstract: A foldable chair frame includes a linking unit for connecting foldably a leg member to a seat member of the chair frame. The linking unit includes a first linking plate with an upper end pivoted to the seat member, a second linking plate with a lower end pivoted to the leg member, a resilient locking plate with an upper end pivoted to the seat member, and a locking pin extending through an elongated hole in the locking plate. The locking pin interconnects foldably adjacent ends of the first and second linking plates, and has a narrower pin section slidable along the elongated hole during pivoting movement of the first and second linking plates relative to each other. The locking pin further has a wider pin section which engages an enlarged hole end of the elongated hole when the first and second linking plates are unfolded from each other for locking the first and second linking plate at an unfolded state.
