The table with a porcelain-enameled steel tabletop provides a magnetic, erasable writing surface directly on the tabletop. The tabletop is defined by opposed upper and lower surfaces and a peripheral side edge, and is formed from porcelain-enameled steel. The porcelain-enameled steel may include a steel layer, having opposed upper and lower surfaces, and a porcelain layer enameled on the upper surface of the steel layer. The porcelain layer defines the upper surface of the tabletop, providing the magnetic, erasable writing surface. At least one leg is secured to the lower surface of the tabletop and extends downwardly therefrom. A protective strip may be secured to, and cover, the peripheral side edge of the tabletop. The protective strip may further be secured to, and cover, a portion of the upper surface of the tabletop and a portion of the lower surface of the tabletop.

A desk lifting structure contains: a horizontal rod, an actuation rod, and two legs. The horizontal rod includes two orifices and two locking grooves. The two locking grooves have two engagement portions, two openings, and two guide portions respectively. The actuation rod is located beside and is parallel to the horizontal rod, and the actuation rod includes two movable joints. The two legs include two movable supports and two holders individually. The movable supports have two connection members respectively, the two legs are connected with two ends of the actuation rod respectively, the two connection members have two side plates individually, and the two side plates have two first fixing apertures and two second fixing apertures respectively.

A table assembly comprising a worktop, a frame supporting the worktop, an integrated drive subassembly, a memory storing defined conditions, a control system including a user input control interface and at least one processor, the input control interface for receiving user commands to initiate changes in worktop height, the processor programmed to perform the steps of a) at any time, respond to direct manual user input via the interface to change the worktop height and b) enable a reminder function to periodically change the worktop height by i) monitoring worktop use, ii) comparing worktop use to at least one of the defined conditions, iii) after the at least one condition is met, providing a signal to the user to change the worktop height to a different position, iv) monitoring for user input via the interface to change the worktop height and (v) upon each of the worktop height being changed prior to providing a signal to the user to change the worktop height and the worktop height being changed subsequent to providing a signal to the user to change the worktop height, repeating steps (i) through (v).

A table arrangement includes a height adjustment mechanisms for movement of one or more height adjustable tabletops. When more than one tabletop is present, each of the tabletops can be independently moveable. Embodiments of the table arrangement can be configured so that a user can manipulate an actuation mechanism to have the tabletop automatically moved to a pre-selected position without the user having to manually control the actuation mechanism to cause the tabletop to move to that pre-selected position.

A power-driven table stand with combining mechanotronics includes: a horizontal bar structure (10); a pair of supporters (20), connected at two sides of the horizontal bar structure (10); a pair of vertical post structures (30), connected to each of the supporters (20) and having a motor (31); and an electrical device (40), having a controller (41) and a guide wiring (45), wherein the controller (40) is disposed on the horizontal bar structure (10), the guide wiring (45) is stored and hidden in the horizontal bar structure (10) and each of the supporters (20), and electrically connected to the controller (41) and the motor (31). Accordingly, power wires and signal wires can be effectively and properly stored and hidden.

A length-adjustable support device, comprising a first rod, a second rod, a bearing formed on the first rod for axially movably mounting the second rod on the first rod such that the second rod is movable in a translation motion relative to the first rod, and a movable fastening element for interlockingly axially fastening the movable second rod to the first rod by interlockingly fastening the fastening element to a mating interlocking-connection element, the mating interlocking-connection element for the interlocking connection to the fastening element. The aim of the invention is that the interlockingly locked length of the support device can be temporarily adjusted by changing the length of the support device.

A height adjustable table assembly system comprising a worktop, a frame, a height adjustment subassembly integrated into the table assembly and adapted to cause worktop elevation adjustment, a user interface and a processor programmed to perform the steps of, while the worktop is at a current elevation position, upon sensing a quick multiple activation of the interface, controlling the height adjustment subassembly to move the worktop to a stored elevation position and upon sensing a prolonged activation of the interface, controlling the height adjustment subassembly to change worktop elevation while the prolonged activation persists.
