Disclosed is a desk system having a freestanding leg assembly, a frame being attachable to an upper portion of the freestanding leg assembly and an adjustable height desktop platform comprising a table top and a supporting leg assembly. The supporting leg assembly may extend between the frame and the table top and the supporting leg assembly may have a scissor lift for adjusting the height of the table top away from the freestanding leg assembly. Disclosed is a desk system having a telescoping leg assembly, configured to adjustable raise or lower a table top of the desk. Disclosed is a desk system with an interface to power the adjustable desk, wherein the interface is visible and operable through the table top.

An elevation working platform includes a lower support and an upper support. At least one group of X-type elevation mechanisms is provided between the lower support and the upper support. The elevation working platform further includes an elastic element. A first end of the elastic element is connected between two end points of a first support rod or a second support rod. A second end of the elastic element is connected to the lower support or a second hinging seat capable of sliding relative to the lower support. Using the X-type elevation mechanisms, the front and back positions of the upper support do not change in an elevating process of the upper support, the structure is simple and practical, and the cost is relatively low.

A height adjustable desktop includes an upper work surface platform, and a base platform, which configured to rest on an existing desk, platform, surface, or table. The height adjustable desktop further includes a height adjustment mechanism that includes two sets of two arms that connect at pivot points along their lengths so that the arms configured to move in a scissoring motion to raise and lower the upper work surface platform. The height adjustable desktop also includes two actuators that apply a force to the two sets of two arms, the actuators each containing feedback sensors that provide data regarding the current position and distance each actuator has extended, retracted or moved.

An expandable and contractable storage device comprised of a frame, X-bars, a leveler, a movable bar, rolling wheels and attachment guides. The frame includes at least one elongated support element having a support ledge. The leveler is connected to the moveable bar and a grooved shaft. The rolling wheels are attached to carriages and the movable bar are located inside elongated U-shaped channels and channels of the attachment guides. The X-bars are attached to the carriages and the attachment guides. Stoppers are movably located inside the elongated U-shaped channels and the channels of the attachment guides. The rotation of the leveler will rotate the grooved shaft and move the movable bar in a forward direction forcing the rolling wheels to rotate and translate forward along the channels and the X-bars will move in an upward or downward direction and the frame moves in a downward or upward direction.

The present disclosure discloses a desk-mounted lifting platform comprising a workbench, an upper support and a low support. The workbench is connected to the upper support. A first lifting arm and a second lifting arm are arranged between the upper support and the lower support. The first lifting arm and the second lifting arm are X-shaped and hinged at an intersection thereof. An upper end of the first lifting arm is hinged with the upper support. A lower end of the first lifting arm is slidably fitted on the lower support. A lower end of the second lifting arm is hinged with the lower support. An upper end of the second lifting arm is slidably fitted on the upper support. A gas spring is arranged between the upper support and the lower support. The gas spring is used for providing a lifting force to lift the upper support.

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.
