摘要： A chair seat sliding and locking mechanism (4) includes a positioning tube (41) and a sliding seat (42). The positioning tube (41) is mounted to a rod (13) of a chair base. The positioning tube (41) is rotatable relative to the rod (13) but is not longitudinally slidable. The sliding seat (42) includes a coupling portion (421) securely coupled with a chair seat (2). The coupling portion (421) includes a receiving portion having a receiving hole (423) with a catching portion (425). The positioning tube (41) is received in the receiving hole (423). When the positioning tube (41) is rotated relative to the rod (13) to a first position in which a positioning portion (411) of the positioning tube (41) disengages from the catching portion (425), the sliding seat (42) is movable along the positioning tube (41). When the positioning tube (41) is rotated relative to the rod (13) to a second position in which the positioning portion (411) engages with the catching portion (425), the sliding seat (42) is fixed relative to the positioning tube (41).

摘要： A chair includes a base (1) having a guiding rod (13). A connecting frame (3) is mounted to a backrest (2) and is pivotably connected to the base (1). A seat (4) includes a rear end pivotably connected to the connecting frame (3). An operative frame (5) includes a rear end pivotably connected to the connecting frame (3). A sliding sleeve (55) is mounted on a front end of the operative frame (5) and is mounted around the guiding rod (13). At least one supporting plate (6) includes a first end pivotably connected to the front end of the operative frame (5) and a second end pivotably connected to a front end of the seat (4). When the backrest (2) is moved backward, the connecting frame (3) is actuated to move the operative frame (5) and the seat (4) forward, and the at least one supporting plate (6) is moved to an extended position to move the front end of the seat (4) upward.

摘要： A leisure chair includes a seat (2) movably mounted on top of a base (1). The seat (2) includes a front rod (21) extending between two lateral rods (22,31). A backrest (3) is connected to the rear side of the seat (2). A footrest unit (4) includes at least one first link and at least one second link. Forward movement of the seat (2) causes the at least one first link and the at least one second link to pivot and causes the footrest unit (4) to fold and move to the storage position below the seat (2). The at least one first link and the at least one second link form a folded part of the footrest unit (4). Rearward movement of the seat (2) causes the at least one first link and the at least one second link to pivot and extend and causes the footrest (4) to extend and move to the extended position in front of the seat (2).

摘要： An angle adjusting/positioning device includes first and second sleeves (11,21) fixed to a backrest (6) and a seat (7) of a chair. The first sleeve (11) has a first axle hole (13) and a first toothed portion (14). A second sleeve (21) includes a second axle hole, a second toothed portion (24), and a positioning portion (26). A third sleeve (411) has a third axle hole and an actuating portion (414). An axle (5) extends through the first, second, and third axle holes. A handle (42) fixed to the third sleeve is operable to move the actuating portion relative to the positioning portion, causing the second toothed portion to engage with or disengage from the first toothed portion. An angular position of the backrest relative to the seat is adjustable when the second toothed portion disengages from the first toothed portion. The angular position of the backrest is fixed when the second toothed portion engages with the first toothed portion.

摘要： A leg rest assembly includes two connecting boards (13) fixed to an underside of a seat (6) of a chair. An actuation rod unit (3) and a link unit (4) are mounted to each connecting board (13). A rear end of each link unit (4) is pivotably connected to one of the connecting boards (13) and one of the actuation rod units (3). Each link unit (4) has a slot (414) aligned with a guiding groove (15) of one of the connecting boards (13). A guiding rod (415) extends through the slot (414) of each link unit (4), the guiding groove (414) of each connecting board (13), and each actuation rod unit (3). A mounting plate (5) is pivotably connected to a front end of each link unit (4). An operative rod (2) is operable to cause movement of the actuation rod units (3) and to move the mounting plate (5) between a first position in front of the base (1) and a second position received in a compartment (17) between the connecting boards (13).

摘要： A swingable chair chassis comprises a rocker seat including a chamber defined between a bottom wall and a peripheral wall. The bottom wall includes a slot extending in a front/rear direction. A lid is securely mounted to a bottom of the seat and the rocker seat. A supporting seat is disposed in the chamber of the rocker seat. The supporting seat includes a central portion having an insertion hole coupled with chair post. The supporting seat includes an arcuate supporting face formed on an upper side thereof and abutting against a lower face of the lid. A plurality of elastic elements is disposed between the bottom wall of the rocker seat and the supporting seat and provides movement elasticity when the rocker seat swings forward or rearward relative to the supporting seat. The supporting face abuts against the lower face of the lid during swinging movement of the rocker seat.
