The invention relates to a lifting device using fluid as a damping medium to form a driving force. It has an outer tube, an inner tube, a guiding assembly and a spring using fluid as a damping medium to achieve a lifting effect, one end of the inner tube being inserted in the outer tube from one end of the outer tube and being fixedly connected with the guiding assembly, a portion of the guiding assembly being in contact with the inner wall surface of the outer tube to implement rolling friction or sliding friction, one end of the spring being positioned in the outer tube, the other end of the spring penetrating through the inner tube and being connected with the inner tube

A dual-column office table includes two oppositely disposed stationary upright columns with a connecting rod transversely connected therebetween, two guiding columns separately disposed in the two stationary upright columns, at least one steel ball sleeve fitted on either guiding column, two driving units separately disposed in the two guiding columns, and a table top to which a top portion of each guiding column is fixedly connected. A bottom end of each guiding column is provided with a limiting structure protruding outward. A bottom end of the each driving unit is fixed to a respective table base provided at bottom portion of each stationary upright column. The table top has a bottom surface fixedly connected with a fixing seat and is provided with a lifting control switch, the lifting control switch being connected with the driving units and having an end disposed in the fixing seat.

A single-column conference table includes a base, a table top, and a lifting mechanism. The lifting mechanism includes an upright column having a bottom portion fixed to the base. A first accommodating chamber is defined inside the upright column. A lifting sleeve is provided in the first accommodating chamber. A second accommodating chamber is defined inside the lifting sleeve. The lifting sleeve is fixed to the table top. A driving unit is provided in the second accommodating chamber. The driving unit is a gas spring. A bottom of the gas spring is fixed to the base together with the upright column. A top of the gas spring is fixed to the support seat. The table top connected with the support seat can be lifted or lowered through the gas spring. The conference table is more stable and reliable during the lifting operation and can prevent the table top from rotating.

A furniture control system has a first and a second control unit to which a first and a second actuator are connectable. The first control unit is configured to control the first actuator based on first actuation data and comprises a first data pool unit for storing first data including the first actuation data. The second control unit is configured to control the second actuator based on second actuation data and comprises a second data pool unit for storing second data including the second actuation data. The control system is configured to synchronize the first and second data upon a change of the first and/or the second actuation data.

Provided is a length-adjustable column with a standpipe having a longitudinal axis, a length-adjustment device arranged in the standpipe with a portion displaceably-mounted along the longitudinal axis with respect to the standpipe and an anti-rotation locking device for locking the portion against a rotation around the longitudinal axis relative to the standpipe. The anti-rotation locking device includes an inner element, which is fastened to an outer surface of the portion, and an outer element, which is fastened to an inner surface of the standpipe. The inner element cooperates with positive locking with the outer element against a rotation around the longitudinal axis, and is displaceably guided along the longitudinal axis by the outer element. The inner element is connected with the portion through a substance-to-substance connecting layer.
