ABSTRACT:
In a display or the like device, a flexible sheet is supported in tension within a frame by means of tensioning devices secured to the frame. Each tensioning device includes a movable peg which is engaged in an aperture in the sheet. Each peg can be placed in a position nearer the middle of the space within the frame in which it is retained, or displaced away from the middle of this space, to tension the sheet, and when so displaced, the peg is urged resiliently away from the middle of this space by a spring within the respective tensioning device, to hold the sheet in tension. The tensioning devices thus constitute a simple and compact means of providing for ready interchangability of various display areas in the frame.
