Abstract
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° 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.

Claims Analysis
Total Claims: 9
Claim 1
Independent Claim
170 words
A holder for positioning on or in engagement to a fixed surface comprising a) a base mount having a selected width for engagement to such surface which mount includes a cylindrical portion and a recess defined in part by a curved surface; b) an arm pivotally secured to the mount, such arm having substantially the same width as the base mount; c) the cylindrical portion of the mount and a cylindrical portion on a first end of the arm positioned, in tandem which tandem portions have a width substantially equal to and coterminous with the widths of the base mount and the arm; said cylindrical portions positionable to form an adjustable joint in turn comprising i) a first set of teeth on the mount cylindrical portion; ii) a second set of teeth on the arm cylindrical portion; iii) hand operable fastener means for drawing the portions to engage the sets of teeth; and d) a surface on the arm for engaging the recess curved surface to limit the arm movement.
