Improvements to multipurpose drawing and painting boards fixed to a folding chair or free standing

摘要

A portable drawing board is attachable by clamps at the ends of telescopic foldable support arms to the arms of a tubular chair, and has a telescopic leg (not perceivable in Fig 5) depending from the opposite edge from which said arms proiect. When dismounted from the chair, both arms and leg can be folded to stow away parallel to the undersurface of the board. A sliding ruler is engaged by channels at its ends with the side edges of the board, and may be clamped by a set screw at its centre. The board may bear graduations, and may be provided with a lip along its lower edge for the retention of books or pencils. The board may alternatively be placed upon a table. IMAGE
