ABSTRACT:
A hand rest for mounting on an easel, the hand rest being easily adjusted using only the artist's painting hand, The hand rest includes a cradle having a mounting block retainer and carrying a vise, a mounting cube, a rotating shaft carried by the mounting cube, a positioning assembly carried by the rotating shaft, a support shaft received within the positioning assembly, and a palm rest carried by the support shaft. The hand rest is designed such that the mounting cube may be received within the cradle in one of five orientations to facilitate mounting the hand rest in an equal number of positions on an easel. The rotating shaft is biased toward the mounting cube and bearing surface is disposed therebetween in order to make rotation of the rotation shaft difficult. However, when the artist pulls back on the support shaft, the rotating shaft is pulled away from the bearing surface and is then freely rotated. The positioner assembly is carried by the rotating shaft and includes a slotted opening and a position locking mechanism. Bearing surfaces are defined by the slotted opening to prevent the support shaft from rotating toward the canvas passed a position normal to the rotating shaft. Biasing members are provided for normally maintaining the orientation of the support shaft in a position normal to the rotating shaft. When the artist desires to move the support shaft within the slotted opening and to rotate the rotating shaft, the painting hand pulls the palm rest away from the canvas, thus allowing the rotating shaft to pivot with respect to the mounting cube and the support shaft to slide within the slotted opening.
