Angle adjustable easel

Abstract

A portable easel with adjustable angle between the board support and the ground is provided. The portable easel has three telescopic legs pivotally joined together by an isosceles triangular head. Two legs are connected to the long front side of the head forming a straight line when stretched. One crossing bar connects the two front legs and determines the maximum angle between the two front legs. One leg is connected to the rear angle point of the isosceles triangular head. One end of a telescopic connector is pivotally connected to the rear leg and the other end is connected to a pivotal connector that receives the upwardly folding crossing bar. The pivotal connector is engaged to a rail that is fixed to the triangular head vertically between the two front legs. By adjusting the length of the telescopic connectors the angle of the front surface of the easel to the ground is adjusted.
