An adjustable lifting column for adjusting a piece of furniture comprises a drive assembly, a threaded spindle assembly comprising at least two concentrically arranged threaded spindles, of which an outer threaded spindle concentrically surrounds at least one further threaded spindle, a telescopic tube assembly comprising three concentrically arranged telescopic tubes, and a driver mechanism having an internal thread. The threaded spindle assembly is located within the telescopic tube assembly. Two adjacent threaded spindles of the threaded assembly have a common threaded connection. One of the at least two threaded spindles in the threaded spindle assembly is connected to the drive assembly for driving this one threaded spindle. The outer threaded spindle also has an external thread in which the internal thread of the driver mechanism engages. The driver mechanism is connected to a middle telescopic tube of the three telescopic tubes.

A lifting device with a cable management is provided. The lifting device includes: an outer pipe, an actuation mechanism, a linkage member, a cable, and a cable management component. The actuation mechanism is accommodated in the outer pipe and has a motor and a screw rod. The linkage member is accommodated in the outer pipe and mutually screw-fitted with the screw rod to operate, and moves relative to the outer pipe. The cable has a spiral coiled cable unit. A shaft core line in parallel with the screw rod is defined by the spiral coiled cable unit. The cable management component is disposed in the outer pipe and in parallel to the shaft core line. The spiral coiled cable unit is reeled on the cable management component. Accordingly, the cable may be stably positioned and the cable may be prevented from rubbing or being tangled with the screw rod.

An intelligent automated chair that is configured to have uploaded various operating models to run a sequence of patterns that cause the intelligent automated chair to alternate between various positions. An intelligent automated chair system configured to receive data from various inputs including user input, sensors, biosensors, historical usage, profile, and others to generate a recommended operating model for the intelligent automated chair. An intelligent automated chair system running an operating model that is interruptible manually by a user or as a result of sensed date, which can alter the pattern or parameters of the operating model.

Joint arrangement (10) has a hollow cylindrical receiving cylinder (20) that extends in a cylinder axis direction (Z) and receives one end of a chair column (30) of an active-dynamic wobble chair, the latter movably mounted in a substantially hollow cylindrical outer joint shell (40) composed of joint shell segments (45). Movable mounting of receiving cylinder (20) is achieved by deformable elastic elements (50) arranged to be variable in shape and position in a bearing gap (60) between an outer wall portion (21, 22) of the receiving cylinder (20) and an inner wall portion (41, 42) of the joint shell (40). Receiving cylinder (20) is actuated in a force-dependent manner, whereby shape and/or position of the elastic elements (50) change as viewed in a radial direction (Rs) from changing, preferably reducing, clearance of the bearing gap (60) when the receiving cylinder (20) is actuated in a cylinder axis direction (Z).

A posture correction mechanism includes a carrier attached to a housing, and a gearwheel rotatably attached to the housing, the gearwheel includes a screw hole engaged with a screw which is moveable up and down relative to the housing for driving the gearwheel to rotate relative to the housing, two shafts are rotatably attached to the carrier and each has an arm rest, two gears are rotatably attached to the carrier and engaged with the gearwheel, the gears are connected to the shafts for allowing the shafts to be driven by the gearwheel to rotate relative to the carrier and for allowing the arm rests to be rotated toward or away from the user.

An anti-wobbling adjustable height stool includes an adjusting screw vaving a threaded seat support spindle and a top spindle head and a stool seat assembly. The stool seat assembly includes a stool seat, and a connecting frame connected with a bottom of the stool seat. The connecting frame is opened with an installation hole, and the spindle head penetrating through and being arranged in the installation hole to enable a tight fit of the spindle head with the connecting frame.
