A vertically adjustable support or table with legs each having a pneumatic foot assembly operated to engage roller ball assemblies on the floor surface thereby allowing the table to be rolled. Each pneumatic foot assembly has a piston unit which is operated by pressurized air from a source, which is controlled by a valve on the table, and which is fluidically connected to a piston chamber of the pneumatic foot assembly. Once the table has been rolled across the floor and is in a desired location, the control valve is operated to release the air from the piston chamber and to rest a circular rim of the pneumatic foot assembly, and therefore, the legs of the table firmly against the floor surface for a stationary or fixed positioning of the table.

Described herein is a foldable table capable of being expanded and stably folded. The foldable table includes a table top plate; two matching frames, each including a first frame and a second frame; and two foldable table legs, each including a first support member and a second support member. Each of the first support member and the second support member includes a U-shaped bolt and a spring drum for combining with the two support members. The support member design including the U-shaped bolt and the spring drum allow the foldable table to be expanded without using excessive force. The table top plate includes a first plate body and a second plate body, each of which includes a joint portion, which allows the table to be stably folded.

Sit-stand desk, such as conversion desks, provide a convenient option for desk work by users who desire the option to selectively sit or stand. Often, the vertical distance between a keyboard and monitor differs when in the sitting configuration versus the standing configuration. A sit-stand desk provided herein allows for a user to transition between a sitting configuration and a standing configuration with a single lifting mechanism with a programmable distance variation between the keyboard and monitor. Accordingly, a user may transition between the sitting configuration and the standing configuration without requiring readjustment of the relative distance between the monitor and keyboard.

A folding support structure includes a top support and a leg assembly. The top support has a pivot connector and an assembler, wherein the assembler has an assembling surface. The leg assembly includes a column, which includes a pivotally connected end, a free end, and a wing. The column is pivotally connected to the pivot connector of the top support with the pivotally connected end thereof, whereby the column is pivotable relative to the top support. The wing of the column has an abutting surface. When the column pivots to an unfolded position, the abutting surface of the wing contacts the assembling surface of the assembler, and is secured thereto through a fixing connection approach. By folding a top and legs of a desk, the total volume could be reduced, benefiting the cargo capacity utilization, which therefore increases the shipping efficiency. Furthermore, such a desk can be easily assembled.

An improved, height-adjustable desktop system that accommodates various postures including, but not limited to, seated in a chair at a desk, or standing upright on a floor, or various possible positions in between fully-seated or fully-standing, according to a user's preference. Systems and methods for providing computer-control for height adjustments allowing automatic or remote adjustment or both. The desktop system further providing minimalized footprint and upright design to allow placement in small spaces.

The present invention relates to the technical field of lifting platforms, in particular to an electric lifting table and a control method thereof; which comprising: a table board (1), one side of which is provided with at least one table leg (2); a lifting mechanism, arranged within the table leg (2); a controller (3), connected to the table board (1), and electrically connected to the lifting mechanism; and it further comprises a vibration sensor, electrically connected with the controller, and the vibration sensor is configured to sense vibration of the table board when one knocks on the table board, and the controller is configured to control the lifting mechanism to act according to the behavior that the user knocks on the table board sensed by the vibration sensor, which is user-friendly to operate and low in cost.

A placement lifting platform includes a table board, under which a bracket, scaffolds and bases are arranged. The placement lifting platform further includes a locking structure, a constant force structure and a buffer structure. By setting the constant force structure, the buffer structure and the lock structure, a constant lifting force can be provided. The adjustability function makes the platform more convenient and smooth, its buffering avoids the unnecessary collision between parts, with the special locking structure, it has better locking effect and is practical and convenient, the use effect is optimized and the applicability is improved.

An apparatus for vertically adjusting a lockable compartment contains vertical supports which house an embedded drive track with a cable and pulley system to propel the adjustable compartment to a plurality of levels within the physical dimensions of the structural frame. The engagement of an external signal with a receiver triggers the electric gearmotor assembly to activate the cable and pulley system.

A hand-operated worm gear height adjustable table includes a table top, a base mechanism, a lift mechanism, and a driving mechanism. The base mechanism includes a base and tracks on the base. The lift mechanism includes two parallel first lift arms and two parallel second lift arms which cross with each other to form X-shaped structures. The driving mechanism is connected to the upper ends of the first lift arms and includes two U-shaped slide rails and a driving shaft penetrating through the upper ends of the first lift arms. The center of the driving shaft is provided with a worm gear and a worm. The outer end surface of the worm is sleeved with a first sleeve component and a second sleeve component with a cavity provided therebetween, and the outer end surface of the first sleeve component is sleeved with the first torsional spring.

A desk with integrated light source comprises a worktop (2) having a top working surface (4) and a perimetral edge (5), lighting means (8) of the top working surface (4) comprising at least one adjustable arm (9) having a first end (11) associated with the perimetral edge (5) to move from a lowered rested position wherein it is parallel to the worktop (2) to an operative position raised with respect of the worktop (2) and a second end (12) provided with a light source (10) suitable for directing a light beam towards the top working surface (4) when the adjustable arm (9) is in the raised position, wherein the at least one adjustable arm (9) is adapted to be brought into a plurality of raised operative positions to vary the direction of origin of the light beam emitted by the light source (10).
