ABSTRACT:
A stretcher for a canvas that includes three co-planar elongated members centrally foldable are pivotally interconnected with two horizontal elongated members. One of the elongated members has longitudinal slots along which one of the ends of each of the horizontal elongated members is sidably connected. Upper and lower canvas holders are slidably and adjustably mounted to the third elongated member, keeping the canvas rigidly in place. A supporting leg is removably and hingedly mounted to a predetermined position of the third elongated member and with a spacer member permits a user to achieve a desired inclination for the canvas being supported, when in working state. For storage or transportation, the elongated members are brought in abutting relationship with each other and the horizontal pivoting members are allowed to rotate sliding out one of their respective ends. Then, the elongated members are centrally folded and secured with straps.
