Abstract
A foldable keyboard stand is formed of a pair of elongated leg tubes that are pivotally connected together to form an X-shape which is arranged in an upright position. Horizontally arranged, parallel tubes are secured to the upper and lower ends of the leg tubes to form upper support and lower foot tubes. The support and foot tubes are arranged off-center relative to the axis of the leg tubes so that they extend forwardly, towards a user location, a considerably greater distance than they extend rearwardly. A resilient, foam plastic sleeve is placed upon and substantially covers each of the upper, support tubes opposite extension portions. A resilient, ring-like collar, which is higher than the support upper surfaces, are positioned upon the opposite ends of the support tubes so that a generally flat keyboard may be rested upon the sleeve covered support tubes and laterally restrained between the end collars. An adjustable length brace interconnects the leg tubes so that the angularity of the leg tubes can be adjusted by selectively adjusting the length of the brace for raising and lowering the support tubes in order to locate the keyboard in pre-selected user standing and sitting …
