US 4,144,660 A · Adjustable stretching frame

Abstract

An adjustable stretching frame for stretching sheet materials, particularly canvas paintings, is disclosed. The frame comprises a plurality of individual frame segment members; means for interconnecting the frame segment members with each other to form a frame; means for adjusting the separation between adjacent frames, and means for maintaining the canvas in a spaced apart relationship relative to the front face of the frame. The latter means may comprise a flexible beading mounted on the individual frame segment members. By adjusting the frame segment members in a manner so as to separate them from their adjacent members, thus expanding the overall dimension of the frame, the canvas is stretched over the frame. The stretchable beading is stretched in such a manner as to fill or complete the space between adjacent frame segment members thus maintaining the overall integrity of the shape of the frame. The framing device of the invention is relatively simple in construction yet is particularly suitable for use for mounting very expensive oil paintings or masterpieces and overcomes the difficulties of known frames.

An adjustable stretching frame for stretching canvas paintings comprising:

a plurality of frame and corner segment members having a front face over which a canvas is to be stretched;
means for interconnecting said frame and corner segment members with each other to form a rectangular frame;
means for adjusting the spacing between adjacent frame and corner segment members;
and
means for maintaining a canvas to be stretched on the frame in a spaced apart relationship from the face of said frame comprising:
(a) a stretchable bead, and
(b) means for mounting said stretchable bead to said frame and corner segment members adjacent to an edge of said segment members, wherein when adjacent frame segment members are separated by said adjustment means, said stretchable bead is stretched between the adjacent frame segment members.
