<p>A chair (10) for supporting bars is comprised of telescoping sections (12, 14, 16) which lock in an extended position. The chair is intended for supporting the reinforcing bars utilized in reinforced concrete construction, but can also support other long bodies. The sections of the chair can be extended and locked individually, so the height of the chair is determined by which sections of the chair are extended and which sections are collapsed.</p> |
