Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a three-dimensional puzzle in which divided pieces are set on a base to assemble a predetermined three-dimensional picture pattern.

[0002]

2. Description of the Related Art Conventional three-dimensional puzzles are those in which a piece is simply fitted into a frame, those in which a jigsaw puzzle is simply raised three-dimensionally, those in which magnets are used as means for connecting pieces, and many in a core material. Is known in which a circular hole is provided, and a pin provided on a bridge is inserted into the hole.

[0003]

In the above-mentioned conventional three-dimensional puzzles, those in which a piece is merely fitted into a frame are those whose pieces have a small shape or whose height is high, the assembly is unstable, and a three-dimensional object is represented. Not suitable for In addition, in the case where the jigsaw puzzle is simply raised three-dimensionally, it is difficult to adjust the fit. Further, in the case of using a magnet as a connecting means for the pieces, designing such that the pieces do not repel each other due to the magnetic force is a great limitation in terms of three-dimensional expression. Also, in the case of assembling by inserting the pin provided on the piece into the circular hole of the core material, since the piece rotates around the pin, it requires cumbersome operation to fix it at a predetermined position on the piece, and the pin If the length is long, there is a problem that the piece is difficult to be fixed at a predetermined position. Also, in any of the three-dimensional puzzles described above, since the pieces are formed at a height having a side surface shape along the loop of the pieces by the height of the three-dimensional pattern from the base, a large amount of material is required. However, there is a problem that the weight becomes heavy.

In view of the above, according to the present invention, the fitting portion of the piece fitted into the mounting hole of the puzzle base is firmly fixed, so that the piece does not move and is stable. An object of the present invention is to provide a three-dimensional puzzle that is lightweight and strong and is suitable for expressing a three-dimensional object.

[0005]

In order to solve the above-mentioned problems, a three-dimensional puzzle according to the present invention is provided with regular polygonal mounting holes provided at equal intervals on a base, removably mounted in the mounting holes, and combined. A leg is provided on the back surface of each of the pieces that form a three-dimensional picture pattern, a notch step is formed below the leg, and a lower part of the notch is fitted to the fitting hole. The leg portion and the fitting portion are plate-like bodies radially arranged toward the corners of the mounting hole so as to correspond to the shape of the mounting hole.

Further, in the three-dimensional puzzle of the first aspect, it is preferable that the leg is formed in a taper of a downward constriction, and a corner at the outer lower end of the plate-like body of the fitting portion is cut off. preferable. In the three-dimensional puzzle of the first, second or third aspect, the base may be formed in an arcuate curved surface, and the surface of the piece and the notch step may be inclined along the curved surface.

According to the present invention having the above-described structure, the fitting of the piece into the mounting hole is performed by pushing the fitting portion into the mounting hole until the notch step provided on the leg on the back surface of the piece hits the surface of the base. Adjustment of the degree of fitting is unnecessary. And since the fitting part is a plate-like body radially arranged toward the direction of the corner of the mounting hole so as to correspond to the shape of the mounting hole, when the fitting part fits into the mounting hole, the fitting part becomes The piece is fixed without rotation.

Further, since the legs are provided on the back surface of the piece, even if the piece becomes higher, only the legs become higher, so that less material is required and the weight is reduced. The leg portion has sufficient strength without bending since the plate-like body is radially arranged toward the corner of the mounting hole.

If the legs are tapered downward, the legs are not in contact with each other when the pieces adjacent to the pieces already fitted in the mounting holes are fitted, so that they can be easily fitted. Further, if the corner at the outer lower end of the plate-shaped body of the fitting portion is cut off, the fitting portion easily enters the mounting hole because the corner is not supported. Also, the base is formed in an arcuate curved surface,
If the surface of the piece and the notch step are inclined along the curved surface, the three-dimensional effect is further increased.

DESCRIPTION OF THE PREFERRED EMBODIMENTS One embodiment of the present invention will be described below with reference to the drawings. FIG. 1 is a perspective view showing an embodiment of the three-dimensional puzzle according to the present invention in the middle of assembly, FIG. 2 is a perspective view of the completed puzzle, FIG. 3 is a perspective view of a piece, FIG. 4 is a bottom view of the piece, and FIG. FIG. 6 is a partial bottom view in a state fitted in the mounting hole.
2 is a partial sectional view of the same.

In FIGS. 1 to 6, reference numeral 1 denotes a plastic base, and the board surface is formed horizontally.
Square mounting holes 2 of the same size are provided in a mesh shape at regular intervals on the board surface. The mounting hole 2 is not limited to a square, but may be a regular polygon. Reference numeral 3 denotes a plastic piece obtained by dividing a three-dimensional picture pattern, and a leg 4 is integrally provided on the back surface of the piece 3. The thickness of the piece 3 is arbitrary, but can be made thin because of the presence of the legs 4. The leg 4 differs depending on the shape of the mounting hole 2, and is formed of a plate-like body radially arranged toward a corner of the mounting hole 2. As shown in the drawing, the square shape is formed as a plate-like body radially from the center of the piece toward the four corners of the mounting hole 2.

The leg portion 4 is formed to have a tapered downward constriction, and a horizontal notch step 5 is formed below each plate-like body of the leg portion 4. The plate-like portion is a vertical fitting portion 6 in which the outer end of the plate-like body is fitted near the inner corner of the mounting hole 2. Further, a corner portion of the outer lower end of the plate-shaped body of the fitting portion 6 is cut off 7.
Note that the resection 7 may be formed in a radius.

Next, FIG. 7 shows a case where the mounting holes 2 provided on the board surface of the base 1 are arranged in a staggered manner, and FIG. 8 shows a case where the mounting holes 2 are in a regular hexagonal shape. In this case, the leg portion 4 and the fitting portion 6 are formed of plate-like bodies arranged in six directions. FIG. 9 shows a case in which the base 1 is formed in an arcuate curved surface, and the pieces 3 and the cutout steps 5 are inclined along the curved surface. The three-dimensional effect will increase more than the puzzle.

[0014]

According to the present invention, when the fitting portion of the piece is fitted into the mounting hole, the piece is prevented from wobbling and rotating, so that the piece can be fixed at a predetermined position and there is a fear that the piece is broken during assembly. You can concentrate on the assembly without having to, and after completion, you can decorate it with peace of mind for viewing. Also, since the legs have no risk of bending, the pieces are stable even if the distance between the board and the pieces is small, which contributes to the diversification of the expression form and the diversification of the base.
