A supporting device for a height adjustable table (1) comprises a first (3) and a second supporting element (3′) respectively having a first, a second, and a third liner component (5, 5′, 6, 6′, 7, 7′) arranged in a manner displaceable relative to each other to cause a change of length (L) of the supporting elements (3, 3′). The first (5, 5′), the second (6, 6′) and the third liner component (7, 7′) are coupled such that a displacement of the second to the first liner component synchronously causes a displacement of the third to the second liner component. The supporting device comprises a synchronization device to synchronize the displacement of the second liner component (6, 6′) to the first liner component (5, 5′) or the displacement of the third liner component (7, 7′) to the second liner component (6, 6′) between the first and the second supporting elements.

A collapsible, adjustable height table with a compact folded configuration and a range limiter to secure selected table heights.

A cordless height-adjustable instrument table is disclosed. The table includes a plurality of vertical support legs that are equally spaced at each side of a centralized height-adjustment column that is fixedly attached to the bottom portion of the table. The centralized height-adjustment column is fixedly placed above a four-wheel base that is coupled to a motor housing including a charging port, a rechargeable lithium battery pack, and electronic components being provided therein. The table further includes easy touch buttons for raising and lowering the table and a plurality of table extensions that increase the length and width. In practice, the user can actuate the easy touch buttons until a desired height of the table is obtained. A readily available 12-hour rechargeable lithium battery from retailers or manufactures is integrated for prolonged use of the table.
