[0001] The present invention relates to a jigsaw puzzle, and more particularly to a foldable
jigsaw piece and a foldable jigsaw frame assembly that are capable of folding.
2. Description of Related Art
[0002] Conventional jigsaw puzzles, including three-dimensional (3D) jigsaw puzzles and
plane jigsaw puzzles, are greatly mature products. Besides drawings, configurations
and difficulty of basic characteristics determining whether jigsaw puzzles are attractive
to consumers, various strange jigsaw puzzles become new focuses. However, configurations
of conventional jigsaw pieces greatly limit designing jigsaw puzzles.
[0003] Conventional jigsaw pieces include 3D jigsaw pieces and plane jigsaw pieces. A conventional
3D jigsaw piece may fold at a single rotational direction for a specific angle. Generally,
a folding angle of the conventional 3D jigsaw piece is not larger than 90 degrees.
Because a 3D jigsaw piece is assembled into a predetermined configuration, the folding
angle thereof is constant. The folding structure of the jigsaw piece is only used
for a single-sided 3D jigsaw puzzle with a predetermined configuration and therefore
limits design variation of jigsaw puzzles.
[0004] Conventional jigsaw frames are used to hold and decorate jigsaw puzzles and at most
demonstrate the obverse and reverse sides of jigsaw puzzles. Showing the reverse side
of a jigsaw puzzle needs to disassemble, detach, flip over and re-assemble the jigsaw
puzzles to the jigsaw frame, which disadvantages use and demonstration of jigsaw puzzles.
[0005] The main objective of the invention is to retrieve the defective conventional technologies
and provide a foldable jigsaw piece that is capable of folding and reversely folding
and a foldable jigsaw frame assembly being capable of demonstrating both obverse and
reverse sides of a jigsaw puzzle is provided based on the foldable jigsaw piece.
[0006] The present invention achieves the aforementioned objective through the following
technologies.
[0007] A foldable jigsaw piece in accordance with the present invention comprises: a first
piecing member, a second piecing member and a connecting member that is longitudinal,
wherein the first piecing member and second piecing member are connected to each other
through the connecting member; each of the first and second piecing members is capable
of pivoting relative to the other for an angle from 0 to 180 degrees to fold the foldable
jigsaw piece into an obversely or reversely folded configuration; and each of the
first and second piecing members has edges and at least one of the edges has a protruding
or notched Ω-shaped engaging member for connection with another jigsaw piece. The
present invention is capable of folding into the obverse or reverse configuration
so that designing three-dimensional jigsaw puzzles is more limitless. The present
invention allows obverse and reverse illustrations or configurations so improves development
of three-dimensional jigsaw puzzles. Various three-dimensional jigsaw puzzles may
be designed for high market competitiveness.
[0008] A foldable jigsaw frame assembly based on the aforementioned foldable jigsaw piece
comprises at least two jigsaw frames and adjacent jigsaw frames are connected through
a frame boundary that is assembled from multiple foldable jigsaw pieces; each jigsaw
frame is capable of pivoting relative to an adjacent jigsaw frame for an angle from
0 to 180 degrees to fold the foldable jigsaw frame assembly into an obversely or reversely
folded configuration; and each jigsaw frame has an inside annular edge and multiple
protruding or notched Ω-shaped engaging members formed on or defined in the inside
annular edge for connection with jigsaw pieces. Such jigsaw frame assembly allows
to embed multiple jigsaws therein simultaneously, may show both obverse and reverse
illustrations of the jigsaws and may be folded for storage and carrying. The foldable
jigsaw frame assembly may comprise at least three the jigsaw frames and is capable
of folding into a Z-shaped folded configuration for compact volume.
[0009] The connecting member of each foldable jigsaw piece is a column and has two opposite
side edges connected respectively to and corresponding to the first and second piecing
members and each side edge has a narrowed neck formed thereon and connected to a corresponding
one of the first and second piecing members.
[0010] Each of the first and second piecing members of each foldable jigsaw piece has an
obverse surface, a reverse surface and two inclined surfaces; and the inclined surfaces
are formed respectively on the obverse and reverse surfaces and are defined adjacent
to one side edge of the connecting member.

[0014] The following descriptions are accompanied with the aforementioned attached drawings
to explain the present invention.
[0015] With reference to Fig. 1, a foldable jigsaw piece 1 comprises a first piecing member
11 and a second piecing member 12. The first piecing member 11 and second piecing
member 12 are connected to each other through a connecting member 13 that is longitudinal.
The connecting member 13 may be a column. 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.
[0016] 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.
[0017] 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 SZ-shaped engaging member formed on the outer side for connection
with another foldable jigsaw piece 1 or conventional jigsaw piece.
[0018] The present invention may modify the foldable jigsaw piece 1 to have different Ω-shaped
engaging member arrangement. With further reference to Fig. 9, a second embodiment
of the foldable jigsaw piece 2 has two notched Ω-shaped engaging member defined respectively
in the edges of each of the first and second piecing members 11, 12. A protruding
Ω-shaped engaging member is formed on the outer side of each of the first and second
piecing members 11, 12. With further reference to Fig. 10, a third embodiment of the
foldable jigsaw piece 3 has two protruding Ω-shaped engaging member formed respectively
on the edges of each of the first and second piecing members 11, 12. A notched Ω-shaped
engaging members is formed on the outer side of each of the first and second piecing
members 11, 12. With further reference to Fig. 11, a fourth embodiment of the foldable
jigsaw piece 4 has one edge of each of the first and second piecing members 11, 12
being straight. The other edge has a protruding Ω-shaped engaging member formed on
the edge. A notched Ω-shaped engaging member is defined in the outer side.
[0019] With further reference to Fig 12, a first embodiment of a jigsaw frame assembly in
accordance with the present invention is formed based on the aforementioned foldable
jigsaw piece and has three jigsaw frames 51, 52, 53 connected through the connecting
members 13. The jigsaw frame 53 on the right side is illustrated partially. 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 foldable 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.
[0020] 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.
[0021] With further reference to Fig. 16, a second embodiment of the foldable jigsaw frame
assembly in accordance with the present invention has five jigsaw frames 51, 52, 53,
54, 55 that are assembled and embedded respectively with the jigsaws 61, 62, 63, 64,
