  • Patent number: 9204726
    Abstract: A foldable chair includes a seat frame unit, a leg frame unit, and a leg frame assembling unit. The leg frame unit includes two leg frames and is pivotable relative to the seat frame unit to change between an unfolded use state and a folded state. The leg frame assembling unit includes at least one resilient fastener and at least one pusher. The resilient fastener has a locking head to immobilize the one of the leg frames in the unfolded use state. The pusher has a protruding portion to push the locking head that is retracted inwardly from the seat frame unit, thereby releasing the one of the leg frames from the unfolded use state relative to the seat frame unit.

  • Patent number: 7066099
    Abstract: A foldable article of furniture includes a surrounding top supported frame with a plurality of engaging members secured thereon and extending downwardly therefrom. A plurality of supporting legs have couplers secured on upper sections thereof. A joint interconnects a lower portion of each engaging member and a proximate portion of each coupler such that the proximate portion is turnable and is uprightly movable relative to the lower portion. A locking member is disposed to lock the proximate portion from turning relative to the lower portion when the proximate portion is in an upper position, and to set the proximate portion free from being locked when the proximate portion is in a lower position. A biasing member biases the proximate portion upwardly.
