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: 6095597Abstract: A collapsible chair includes a pivotal member having a lower pivot hole for connecting with an upper portion of two front feet and an upper hole for connecting an upper end of two rear feet. The lower pivot hole and the upper pivot hole are not aligned but on different surfaces. Two touch blocks are respectively fitted around a lower horizontal rod of the two front feet and of the two rear feet. Each touch block has a position edge protruding from a front side or a rear side. A seat is provided with a pivot base at two opposite sides for connecting with the two rear feet, and each pivot base has a recessed flat face respectively in an upper and a lower side. A backrest is provided with an armrest at two opposite sides, and the armrest has an acute angle member formed under it. Then the collapsible chair is safe and stabilized in an extended condition, and safe and steady and space-saving in a collapsed piled-up condition.Type: GrantFiled: April 22, 1999Date of Patent: August 1, 2000Inventor: Tsung-Chieh Huang

Patent number: 5954391Abstract: 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.Type: GrantFiled: May 6, 1998Date of Patent: September 21, 1999Inventor: Donald F. Gray

Patent number: 5897161Abstract: Folding chair (10) comprising a seat (20) carried by righthand and lefthand front legs (11a, 11c) and righthand and lefthand rear legs (11b, 11d), and a back-rest (14) associated with said rear legs (11b, 11d) . Front legs (11a, 11c) and rear legs (11b, 11d) are interconnected for relative rotary movement. Likewise, the pairs of lefthand legs (11a, 11b) and righthand legs (11c, 11d) are interconnected for relative rotary movement.Type: GrantFiled: February 12, 1998Date of Patent: April 27, 1999Inventor: Peter W.

Patent number: 5887888Abstract: A combined cart and chair assembly includes a front support, a seat frame, a rear leg frame, a container retaining frame, and a container. The front support has a handled upper section and a wheeled lower section. The seat frame is mounted pivotally to the front support between the upper and lower sections. The seat frame is foldable rearwardly and is stretchable forwardly. The rear leg frame has a top end mounted pivotally to the front support between the upper and lower sections above the seat frame so as to extend downwardly and rearwardly from the front support when the seat frame is stretched. The rear leg frame is pivoted to the seat frame and is foldable toward the wheeled lower section. The container retaining frame is provided behind the seat frame and is mounted pivotally to the front support above the top end of the rear leg frame for turning away from or toward the front support.Type: GrantFiled: September 3, 1997Date of Patent: March 30, 1999Inventor: Chuen-Shyan Tseng

Patent number: 5868469Abstract: A folding chair is composed of a support frame, two seat support arms fastened with the support frame by retaining pieces capable of sliding along the support frame, and a seat mounted on the two seat support arms. The seat can be adjusted in height by sliding the two seat support arms upward or downward along the support frame. The seat is located at a desired height by a counterclockwise moment of couple brought about by the seat support arms and the retaining pieces at the time when the seat support arms are exerted on by the body weight of a person seated on the seat.Type: GrantFiled: March 30, 1998Date of Patent: February 9, 1999Inventor: Liao Tsung Ming

Patent number: 5782528Abstract: 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). The partial extraction of the internal tube (32) from the external tube (31) occurring when the chair is lifted by the back (6) allows the rotation of the seat around the axis of said rear cross-bar (9).Type: GrantFiled: June 12, 1997Date of Patent: July 21, 1998Inventor: Enrico Cioncada

Patent number: 5738408Abstract: A plurality of stackable folding chairs having two sets of legs pivotally attached to each other and a seat pivotally attached thereto. Indentations are formed in a first side of one of the two sets of legs and a protrusion is formed on a second side of the legs at approximately the same location. The chairs are configured to be folded so as to be substantially planar in configuration with the indentations and the protrusions exposed. The protrusions of a first chair can then be positioned within the indentations of a second chair so that the first and second chairs are positioned adjacent each other in a stacked configuration.Type: GrantFiled: August 30, 1996Date of Patent: April 14, 1998Inventor: Henry Wu
