Patent number: 6547321Abstract: A folding chair has a seat, a first leg, a second leg, a first rod connected to the first leg and the second leg, a second rod connected to the first leg and the second leg, and a folding device. The folding device has a first joint and a second joint. The first joint has a guide channel, a circular aperture, and a slant round hole for receiving the first rod. The second joint has a post inserted in the guide channel, a hollow protruded block inserted in the circular aperture of the first joint, a round through aperture, and a slant circular hole for receiving the second rod. A bolt passes through the round through aperture of the second joint and the circular aperture of the first joint. A nut engages with the bolt.Type: GrantFiled: July 17, 2001Date of Patent: April 15, 2003Inventor: Chung-Sen Wu

Patent number: 6547322Abstract: A chair with four sets of leg tubes(22) consisting of two leg tubes(22) attached at their centers in an X position which fold into a collapsed position with leg tubes(22) nearly parallel to each other. Seat tubes(24), and back tubes(44) are pivotally attached to the upper ends of leg tubes(22) at the rear of the chair. Seat tubes(24) are connected to leg tubes(22) at the front of the chair by seat clips(30). This configuration of the chair in the open position, provides a stable structure for the attachment of a seat cover(42) and for the attachment of a mechanism for reclining back tubes(24) and back cover(11). Arm braces(18) extending from the top of leg tubes(22) at the rear of the chair, and connected to vertical tubes(14) extending from near the center of seat tubes(24) support arm tubes(8), which are attached to back tubes(44). Back tubes (44) recline by moving arm tubes(8) to different positions in slots in arm plates(12) attached near the front of arm tubes(8).Type: GrantFiled: August 17, 2001Date of Patent: April 15, 2003Inventor: Edward Michael Marx

Patent number: 6540290Abstract: An improved folding chair includes two side frames each having a front leg, a rear leg, and a linkage bar bridging the front leg and the rear leg, and a first loading bracket and a second loading bracket. The linkage bars are coupled respectively with a tubular rod which is turnable on the linkage bar. The tubular rods respectively attach to a first and a second toggle bar which are pivotally engaged on a toggle joint. The first and the second loading bracket have respectively a first side bar and a second side bar which are pivotally engaged with the first and the second toggle bar in a cross and staggered manner. The first and the second side bar have respectively one end engaged with each other on another toggle joint, and connect respectively to a first loading bar and a second loading bar to form a seating zone.Type: GrantFiled: July 31, 2001Date of Patent: April 1, 2003Inventor: Lausan Chung-Hsin Liu

Publication number: 20030042779Abstract: A reclinable wheelchair which allows a user seated therein to adjust the inclination angle of a seat back rest by himself, and is foldable in the width direction. The reclinable wheelchair comprises a frame foldable in the width direction, a seat assembly arranged in the frame, a seat back rest arranged on a back side of the seat assembly of the frame for pivotal movements between an upright position and an inclined position, actuators for driving the seat back rest and capable of holding the seat back rest at an arbitrary position between the upright position and the inclined position, a reclining lever arranged at a position which allows the user to manipulate, for manipulating the actuators, and a head rest attached to the frame. The head rest is comprised of a head rest body, and an attachment coupled to the left and right ends of the frame and folded up on the width direction as the frame is folded.Type: ApplicationFiled: December 14, 2001Publication date: March 6, 2003Inventors: Ryuji Yamasaki, Takeharu Shizume

Publication number: 20030030305Abstract: A collapsible chair (10), having a frame assembly (16) including a number of frame members (20), the upper ends of the frame members (20) being pivotally attached to upper pivot assemblies (36, 38), and the lower ends being pivotally attached to lower pivot assemblies (30, 32). The frame members (20) are connected such that the frame assembly (16) as a whole expands outwardly from a central area (40) when the chair (10) is unfolded. The frame assembly (16) further including rear members (28) and front support members (50), and a pair of rigid arm rest members (46, 146). A pair of pivot mechanisms (70) and a pair of slide-pivot mechanisms (72) attach the rigid arm rest members (46, 146) to the frame assembly (16) such that the rigid arm members (46, 146) are allowed to slide and pivot as the chair (10) collapses or expands.Type: ApplicationFiled: August 9, 2002Publication date: February 13, 2003Inventor: Harrison Choi
