ABSTRACT:
A stretcher frame for decorative materials used as wall hangings, for artists' canvasses and the like which includes four limbs defining a rectangle, two of which can be folded inwardly at their centers so that the frame can be folded up concertina-fashion. Hinge connections are provided at each corner of the frame and at the mid-points of the folding limbs. The four limbs remain permanently connected by the hinge connections and the folded frame can be easily transported and stored. If the covering material can be folded it can remain in place on the frame when the frame is folded. The hinge connections include flat link members which are normally concealed within slots in the limbs.
