Title: (EN) Height-adjustable workstand support
Abstract:
(EN) A height-adjustable workstand support incorporates a pair of laterally spaced, structurally independent but synchronously driven, screw-type scissor lifts (30) which support a top surface (28) for machinery such as a sewing machine or the like. The support is adapted to convert a fixed-height workstand (2) to one which is adjustable to accommodate operators of different heights, whether sitting or standing.
