The first piecing member 11 and second piecing member 12 are capable of pivoting along the connecting member 13 to fold and change the foldable jigsaw piece 1 into a folded configuration. The folded configuration of the foldable jigsaw piece 1 is shown in FIG. 3. With further reference to FIGS. 4 and 5, each of the first and second piecing members 11, 12 is capable of pivoting relative to the other for an angle from 0 to 180 degrees. With further reference to FIG. 8, the first and second piecing members 11, 12 are capable of pivoting obversely or reversely to fold the foldable jigsaw piece 1 into an obversely or reversely folded configuration.

Enlarged and detailed structures of the first and second piecing members 11, 12 and connecting member 13 are shown in FIG. 6, the connecting member 13 has two opposite side edges connected respectively to and corresponding to the first and second piecing members 11, 12. Each side edge has a narrowed neck 14 formed thereon and connected to a corresponding one of the first and second piecing members 11, 12. Each of the first and second piecing members 11, 12 has an obverse surface, a reverse surface and two inclined surfaces 111. The inclined surfaces 111 are formed respectively on the obverse and reverse surfaces and are defined adjacent to one side edge of the connecting member 13. Furthermore, a thickness of the connecting member 13 is smaller than a thickness of each of the first and second piecing members 11, 12. Such structural design allows one of the first and second piecing members 11, 12 to pivot relative to the other clockwise or counterclockwise for 180 degrees to fold the jigsaw piece 1 into the obversely or reversely folded configuration. For example, the second piecing member 12 pivots to stack over and parallel the second piecing member 11. When the first and second piecing members 11, 12 pivot for 180 degrees and fold the foldable jigsaw piece 1, the connecting member 13 at least partially presses against and supports one inclined surface of each of the first and second piecing members 11, 12, as shown in FIG. 7. At this time the connecting member 13 controls and holds the first and second piecing members 11, 12 so that the first and second piecing members 11, 12 in the folded configuration are aligned with each other without relative movement, as shown in FIG. 3.

As shown in FIG. 1, each of the first and second piecing members 11, 12 of the foldable jigsaw piece 1 of the first embodiment has two opposite edges and an outer side. The edges are defined adjacent to the connecting member 13. One of the edges is straight and the other edge has a notched Ω-shaped engaging member defined in the edge for connection with another foldable jigsaw piece 1 or conventional jigsaw piece. The outer side is defined between the edges and opposite to the connecting member 13 and has a protruding Ω-shaped engaging member formed on the outer side for connection with another foldable jigsaw piece 1 or conventional jigsaw piece.

Each jigsaw frame 51, 52, 53 is capable of pivoting clockwise or counterclockwise relative to an adjacent jigsaw frame 51, 52, 53 along the connecting members 13 for an angle from 0 to 180 degrees to fold the jigsaw frame assembly into an obversely or reversely folded configuration. Each jigsaw frame 51, 52, 53 has an inside annular edge and multiple protruding or notched Ω-shaped engaging members formed on or defined in the inside annular edge to respectively engage multiple protruding or notched Ω-shaped engaging members on an outer edge of each jigsaw 61, 62, 63. The way to piece up a jigsaw puzzle may be piecing a jigsaw 51 then assembling the complete jigsaw 51 into the jigsaw frame 51. Alternatively, the jigsaw 63 and jigsaw frame 53 are pieced simultaneously. A complete jigsaw puzzle is shown as the combination of the jigsaw frame 52 and jigsaw 62 on the intermediate section in FIG. 12.

With further reference to FIG. 13, a frame boundary connected between adjacent jigsaw frames 51, 52, 53 is assembled from the aforementioned foldable jigsaw pieces 1, 2, 3, 4 that are connected and arranged in a column. Each foldable jigsaw piece 1, 2, 3, 4 has the connecting member 13, the first piecing member 11 and the second piecing member 12. According to the descriptions of the foldable jigsaw piece 1 in FIG. 1, each of the first and second piecing members 11, 12 is capable of pivoting relative to the other for an angle from 0 to 180 degrees for the obversely or reversely folded configuration, as shown in FIGS. 14 and 15.
