摘要： A chair assembly includes a supporting frame disposed above a base and including a first guiding groove. A seat is pivotably connected to a backrest. Lower and front guiding wheels are mounted to rear and front ends of the seat, respectively. At least one operating board includes rear and front ends respectively having second and third guiding grooves. The lower guiding wheel is movably received in the first and second guiding grooves. The front guiding wheel is movably received in the third guiding groove. A first operating rod is pivotably connected between the supporting frame and the seat. When the operating rod retracts, the lower guiding wheel is located in rear ends of the first and second guiding grooves, and the front guiding wheel is located in a rear end of the third guiding groove. The seat moves downwards and rearwards, and the front end of the seat inclines upwards.

摘要： An electric-assisted leisure lifting recliner includes a back frame pivotably mounted to a seat frame unit. A footrest unit includes a connecting portion pivotably connected to a front end of the seat frame unit. First and second frames are pivotably connected to a base unit and the seat frame unit and are operable to move the seat frame unit vertically. A telescopic rod is pivotably connected to an actuating block and the connecting portion. An actuator pivotably connected to the actuating block can move the footrest unit to an extended state and to recline the back frame. When the connecting portion abuts against the seat frame unit, the telescopic rod can be shortened to independently recline the back frame. When a length of the actuator is shortened, the first and second frames and the seat frame unit are lifted, and a rear end of the seat frame rises.

摘要： A leisure chair includes a backrest pivotably connected to a seat. A connection seat is mounted between a base and the seat and includes a lower coupling portion mounted to the base, an upper coupling portion mounted to the seat, and two pivotal rod units pivotably connected to two sides of the lower coupling portion, respectively. The upper coupling portion is pivotably connected to the pivotal rod units. When a control rod moves rearwards, a push portion on the control rod actuates a pull rod to control a pneumatic rod for adjusting a rearward inclination angle of the backrest. When the control rod moves forwards, a pressing portion of the control rod presses against two swaying rods to extend the legrest unit, and the center of gravity of the upper coupling portion can be located in front of the center of gravity of the base to provide enhanced lying stability.

摘要： A positioning device includes a clamping seat having first and second clamping members with clamping portions mounted around a fixed rod of a chair having an inclinable seat to which the first clamping member is fixed. An adjusting rod includes a coupling seat having a positioning groove with a low-profile section and a high-profile section. A positioning block is mounted to the second clamping member and includes a protrusion received in the positioning groove. The protrusion is engagable with one of the low-profile section and the high-profile section, so that the clamping portions can be clamp on or disengage from the fixed rod, allowing controlling of movement of the clamping seat along the fixed rod. The first clamping member includes a sidewall having a hole slideably receiving the fixed rod and in slight tight coupling with the fixed rod.

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.

摘要： An angle adjusting/positioning device includes first and second sleeves fixed to a backrest and a seat of a chair. The first sleeve has a first axle hole and a first toothed portion. A second sleeve includes a second axle hole, a second toothed portion, and a positioning portion. A third sleeve has a third axle hole and an actuating portion. An axle extends through the first, second, and third axle holes. A handle 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.
