  • Patent number: 6386627
    Abstract: Rear leg-supported foldable chair including a front leg, a rear leg, a seat and a linking mechanism. The rear leg is pivotally connected with rear end of the seat. A connecting plate is disposed at top end of the rear leg for pivotally connecting with the front leg. Two fixing bent plates respectively extend from lower edges of two lateral fulcrums of the front leg. Each of the fixing bent plates via a linking rod is connected with the other. The linking rod via a movable plate is pivotally connected with the rear end of the seat to form the linking mechanism. When the chair is unfolded, the fulcrums of the rear leg and the linking mechanism directly welded on the front leg will distributively bear the weight loaded on the seat. The front leg and rear leg are firmly connected with each other so that the foldable chair is more rigid and durable.

  • Patent number: 6361105
    Abstract: A chair includes a chair arm (20) coupled to a frame (22, 28) and a cup holder (24) mounted to chair arm (20) for movement between a retracted position lying underneath chair arm (20) to an opened position lying away from the underside of chair arm (20) to hold a cup (26) therein. Cup holder (24) includes first and second arms (40, 42) mounted for pivotable movement about a pivot axis (44) relative to chair arm (20) and one another. When moved to the opened position, first and second arms (40, 42) cooperate to define a circular cup-receiving opening therebetween. Cup holder (24) also includes an interlock (90) to guide relative movement of first and second arms (40, 42) as those arms are moved between retracted and opened positions.

  • 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: 5954391
    Abstract: The three-legged folding chair has a primary frame with two legs and an apex, a secondary frame with two arms and an apex, and a third leg. The secondary frame is pivotally attached to the primary frame by two pivot pins. A back rest is secured to the primary frame adjacent to the primary frame apex. A support seat is attached to the arms of the secondary frame and are spaced from the secondary frame apex. The third leg is connected to the backrest adjacent to the primary frame apex. The apex of the secondary frame is held in a use position by the third leg. The secondary frame intersects the primary frame at an angle of about 66.degree. when held by the third leg. Both pivot pins are held out of axial alignment with each other when in the use position. The ground contact ends of the primary frame legs are under the forward edge of the support seat, the third leg is relatively short and weight is transferred to the third leg. The backrest is spaced forwardly from the primary frame apex.

  • Patent number: 5782528
    Abstract: A folding chair (1) which consists of a seat (5) foldable; two pairs of struts, front (2) and rear (3) which converge on and connect to the chair back (6) functioning as legs and being connected to each other respectively by a rear horizontal cross-bar (9) and a front horizontal cross-bar (8). The rear struts (3) are formed by two tubes (31, 32) slidable one inside the other, the internal tube (32) being fixed by at least one connector (7) to the top of the front strut (2) in correspondence with the chair back, the external tube (31) being fixed to its twin by said rear cross-bar (9).
