  • Publication number: 20090301361
    Abstract: A foldable furniture device includes a support frame having first and second frame bodies opposite to each other in a first direction, and two foldable third frame members opposite to each other in a second direction that is perpendicular to the first direction and interconnecting pivotally the first and second frame bodies. The support frame is operable between a folded state, where the third frame members are folded toward each other so that the first and second frame bodies are close to each other, and an unfolded state, where the third frame members are unfolded. A top member covers detachably a top side of the support frame when the support frame is in the unfolded state.

  • Publication number: 20060158010
    Abstract: A foldable furniture device includes a main frame, and first and second leg frames. Each first or second leg frame includes two spaced-apart leg sections which have top ends pivotally connected to the main frame. The leg sections of the first leg frame respectively have slide rails. The leg sections of the second leg frame respectively have slide pins that extend respectively into the slide rails to connect movably the second leg frame to the first leg frame. A positioning pin is attached to each leg section of the first leg frame, and is movable into a respective slide rail so as to immobilize a corresponding slide pin. Each slide pin is movable between first and second ends of the slide rail when the bottom ends of the first and second leg sections move toward and away from the main frame.

  • Publication number: 20060071532
    Abstract: A seat device for a chair includes at least two outer sheet layers made of a stretchable elastic textile material, and an inner sheet layer of a textile material sandwiched by the outer sheet layers. The inner sheet layer has a second marginal part surrounding substantially an entire area thereof and secured to first marginal parts of the outer sheet layers. An attachment member is associated with the first and second marginal parts and is adapted to be mounted on the chair. The entire area of the inner sheet layer is larger than that of a respective outer sheet layer so that the inner sheet layer creases when the outer sheet layers lay flat. The inner and outer sheet layers form a concaved configuration when a pressure is exerted on the inner and outer sheet layers along a direction transverse to the same.

  • Patent number: 6960004
    Abstract: A lampshade includes first and second annular members, a plurality of spaced-apart flexible supporting rods disposed between the first and second annular members, and a flexible cover sheet body covering the supporting rods. Each supporting rod has first and second ends connected respectively to the first and second annular members. The supporting rods are curved to bulge outwardly to a first position. The first and second annular members are rotatable in opposite directions so as to twist simultaneously the supporting rods to a second position, and are compressible to move toward each other to fold the supporting rods from the second to a third position. The supporting rods are resilient to restore from the third to the first position when the first and second annular members are pulled apart from each other.
