Abstract: A chair frame and a casual chair are provided. The chair frame includes a frame mechanism, a connecting rod system and a seat mechanism. The connecting rod system includes a basic component fixed to the frame mechanism; a first front arm pivotally connected to the basic component; a first rear arm pivotally connected to the basic component; a first transverse arm pivotally connected to the first front arm and the first rear arm; a second transverse arm pivotally connected to the first front arm; a second rear arm pivotally connected to the first rear arm and the second transverse arm; a second front arm pivotally connected to the second transverse arm; and a lifting component pivotally connected to the second front arm and the second rear arm. The seat mechanism includes a hip-leg supporting component, a front rocker arm and a rear rocker arm.

Abstract: A seat frame and a seat with switchable sitting and lying positions are provided. The seat frame includes a frame, a seat cushion, and a backrest connecting rod mechanism with a polygonal planar structure, the polygonal planar structure includes a front swing arm, a back pole frame, and a T-shaped connecting rod. A front end of the back pole frame is hinged to the upper end of the front swing arm. The T-shaped connecting rod includes two straight rods; an end of one of the two straight rods is defined as a first protruding end hinged to the lower end of the front swing arm, an end of the other of the two straight rods is defined as a second protruding end hinged to a back end of the back pole frame.

Abstract: A movable chair device and a chair assembly are provided. The movable chair device includes a chair mechanism and a transmission mechanism. The transmission mechanism includes a primary transmission component and an intermediate transmission component. The primary transmission component includes: a fixing member, a first swing arm, a second swing arm and a first linkage member. The first linkage member is enclosed with the first swing arm, the second swing arm and the fixing member to form a closed-loop connecting rod mechanism. The intermediate transmission component includes a first transmission arm, a second transmission arm and a third transmission arm.

Abstract: A chair backrest mechanism, a chair frame and a chair are provided, including a back supporting member, a hip and leg supporting member, a swing traction unit, a linkage member and an auxiliary traction member. The hip and leg supporting member includes a leg supporting portion and a hip supporting portion. The back supporting member is movably connected to the hip and leg supporting member by the swing traction unit. The auxiliary traction member is pivotally connected to the swing traction unit and includes a first pin joint portion and a second pin joint portion, the first pin joint portion is pivotally connected to the hip supporting portion, the second pin joint portion is pivotally connected to a first end of the linkage member, and a second end of the linkage member away from the second pin joint portion is pivotally connected to the back supporting member.

Abstract: Power line disturbance hold up times are dynamically adjusted based on battery capacity of a plurality of batteries in a plurality of racks by determining which one of the plurality of racks has a fewest number of remaining batteries of the plurality of batteries having the battery capacity. A determination of an amount of the power line disturbance the one of the plurality of racks, having the fewest number of remaining batteries of the plurality of batteries with the battery capacity, is able to support.

Abstract: A graft copolymer of acrylic acid and maleic acid (or anhydride) grafted onto starch, a detergent builder composition containing the graft copolymer and a method of preparing the graft copolymer. These novel starch graft copolymers are highly water-soluble and biodegradable, have strong chelation ability to calcium ions and magnesium ions, and strong pH buffering ability. The composition has no phosphate and aluminosilicate. The composition has excellent anti-redeposition, building, anti-filming, dispersing, threshold crystal-inhibiting and enzyme performance-improving properties.
