Abstract (en)
[origin: US4773174A] The supporting and suspending frame, detachably assembled from a plurality of supporting frame elements, serves to suspend flat reproductions, in particular photographic reproductions, of paper, film or fabric smoothly in the frame by means of tensioning springs. Every supporting frame element has an at least partly circularly curved narrow side and a contiguous flat wide side at right angles thereto. The inside face of the wide side is provided with a supporting member that extends in the longitudinal direction of the wide side and is open in the transverse direction of the wide side. The tensioning springs, which are fastened to the edges of the reproduction by means of eyes, can be suspended directly in and displaced along the supporting member. As a result, it is possible to wrap the reproduction over the wide side and the narrow side toward the back side of the supporting frame element and there fasten it smoothly by means of the suspended tensioning springs, so that the reproduction is clamped or displayed in a "borderless" manner.
