The invention relates to an actuator system (100) for a table (200) having at least two table legs (210) of variable length and a table top (220) held by the table legs (210), characterized in that it comprises at least two master cylinders (10), each having a cylinder (10a) and a piston (10b) movable in the cylinder (10a) and a piston rod (10c) for moving the piston (10b), wherein a slave cylinder (20) having a cylinder (20a) and a piston (20b) movable in the cylinder (20a) for changing the length of the table leg (210) is connected to each of the master cylinders (10) by means of a conduit (40) allowing fluid (30) flow between the master cylinder (10) and the slave cylinder (20), and wherein the piston rods (10c) of the master cylinders (10) are mechanically connected to each other by means of a rigid connecting element (45), and wherein a drive unit (52) in a rigid drive connection (50) with the connecting element (45) is connected to the connecting element (45) for simultaneously moving the pistons (10a) of the master cylinders (10). The invention further relates to a multifunctional table (200) comprising an actuator system (100) according to the invention.

A table frame for a table has a first column and a second column for supporting a table top, a cross member of hollow profile construction by which the first column and the second column are interconnected with each other and a first cantilever support mounted on the top end of the first column and a second cantilever support mounted on the top end of the second column. The first and the second column each have two projections at respective top ends thereof. The cross member, at each end section thereof, has a pair of oblong holes disposed on its lower side and through which the two projections of the respective column extend into the cross member. Each cantilever support has a first and a second flange which are arranged spaced-apart from one another, each of the flanges abutting the cross member on a lateral side portion thereof.

An electric lifting device includes one driving mechanism and at least two transmission mechanisms, the two transmission mechanisms cooperating mutually and connected through a transmission bar assembly, with one transmission bar assembly driven by the driving mechanism. Each transmission mechanism includes a gearbox, a first driving gear, a second driving gear with axes of the first and second driving gears being crossed vertically, and lifting table legs disposed below at least two of the transmission mechanisms and driven by the second driving gear of the corresponding transmission mechanism to be lifted synchronously. The present invention employs only one driving mechanism, and with respect to the structure employing multiple driving mechanisms, the electric lifting device in the present invention can not only prevent interference to guarantee higher consistency, but also reduce devices to lower the difficult in control, thereby significantly reducing the cost.

A height-adjustable table with concealed wiring design is provided herein, which includes table surface, table leg, table foot, driving mechanism, and control device. The table leg is connected between the table surface and the table foot and includes a telescoping tube structure. The driving mechanism includes motor, first threaded rod, and connecting tube. The first threaded rod screwed to one end of the connecting tube and the connecting tube are disposed in the telescoping tube structure. The motor is configured to drive the first threaded rod to alter the length of the telescoping tube structure. The control device includes wiring and a control interface. The wiring is disposed in the telescoping tube structure and spirals around the connecting tube. The wiring transmits power to the driving mechanism and transmits a control signal from control interface to the motor to drive the driving mechanism.
