Abstract
An activated arm stand with a base positioned on or securable to a stationary surface in which the base and an arm with a selected width are connected by a pair of aligned cylindrical portions each having a width less than the width of the arm. The cylindrical potions have V-shaped teeth which are urged together by an adjustable fastener and spring to hold the arm in a selected position. The base includes a surface which engages the arm to prevent its movement into a portion of the 360.degree. rotation even when the teeth are disengaged. The arm stand may include a toothless joint engagement arrangement in which a tooth joint portion is made toothless with a conversion washer.
