PROBLEM TO BE SOLVED: To provide a picture frame that is easy to assemble and that dispenses with a tool for assembling.SOLUTION: A folding picture frame 1 includes: an opening part 7 for displaying a planar exhibit; a plurality of frames a, b, c, d for surrounding the opening part 7; and a plurality hinges 8, 9 for connecting the frames. The plurality of frames comprise two long frames a, c and two short frames b, d, in which the two long frames a, c oppose in parallel to each other across the opening part 7 and in which the two short frames b, d similarly oppose in parallel to each other across the opening part 7, are adjacent at right angles to all long frames a, c, and are each divided into two division pieces b1, b2, d1, d2 at the central part. The plurality of hinges are composed of two frame hinges 8 and four square hinges 9. The frame hinges 8 each rotatably connect the two division pieces to each other in the two short frames b, d, while the four square hinges 9 each rotatably connect at the four corners of the picture frame 1.SELECTED DRAWING: Figure 1 |
