Abstract

Three-dimensional spherical jigsaw toy has pieces with protrusions and cutouts. The protrusions and cutouts in two adjacent pieces correspond to each other. Each piece is in the tangential region of the sphere, so when all the pieces are assembled, a sphere is formed.

The present invention relates to a three-dimensional spherical jigsaw puzzle, and more particularly to a three-dimensional spherical jigsaw puzzle consisting of pieces and a hollow interior. Individual pieces have protrusions and cutouts corresponding to cutouts and protrusions of adjacent pieces, respectively, thereby forming a complete shape when the jigsaw toy is completed.

Jigsaw puzzles are popular with children and even for adults. Existing jigsaw puzzles are generally flat pictures that are cut into pieces, and the pieces are put together to recreate the picture. The different levels of difficulty in completing the jigsaw puzzle can be changed by the amount of pieces to meet the needs of the consumer.

Several jigsaw puzzles, called three-dimensional spherical jigsaw toys, were invented. One of the three-dimensional spherical jigsaw toys consists of cube pieces, each of which has six sides painted in various shapes and can be recombined to form six pictures that correspond to the individual faces of the cube pieces.

Another three-dimensional sphere jigsaw toy has a dimensional frame that includes a horizontal bracket and a vertical bracket. The bracket has a number of holes there. Fit pieces with poles can be installed in the bracket by inserting a pole into the hole to form a three dimensional shape.

In the third three-dimensional spherical jigsaw toy, there are a number of sheets painted with the same picture. The sheets are cut according to the pieces of the jigsaw puzzle. The pieces stick to sheets with different numbers. The pieces have different thicknesses for the three-dimensional effect to be reproduced by the pieces.

However, all existing jigsaw puzzles represent two-dimensional pictures combined only by pieces. There is no true three-dimensional effect on jigsaw puzzles.

The present invention provides an improved jigsaw matching toy which alleviates and solves the above-mentioned problems in order to provide a three-dimensional effect.

The main purpose of the present invention is to make the puzzle matching toy not only increased by the amount of pieces but also by forming and maintaining the three-dimensional spherical jigsaw toy. To provide a jigsaw puzzle that does not use auxiliary assistance such as a bladder and has a true three-dimensional effect.

Other objects, advantages and novel features of the present invention will become more apparent from the following detailed description taken in conjunction with the accompanying drawings.

1, 2, and 3, the three-dimensional spherical jigsaw puzzle according to the present invention is a sphere (1) comprising several pieces (2). Each of the pieces 2 has a uniform thickness and has a protrusion 3 and a cutout 4. As also shown in FIG. 3, each of the pieces 2 has a bottom surface and an upper surface, each of which is partitioned by a lower contour and an upper contour, an inner radius and an outer radius, The inner radius is the distance extending from the center of the sphere to a point on the bottom side, and the outer radius is the distance extending from the center of the sphere to a point on the top. Specifically, the projections 3 and cutouts 4 for each of the two adjacent pieces 2 are formed corresponding to each other and each of the pieces 2 has a top surface with an upper contour and a bottom surface with a lower contour; With projections 3 and cutouts 4, the radius of the sphere 1 first passes through the lower contour and then through the upper contour so that the sphere 1 is rebuilt after all pieces 2 have been combined. do. That is, as can be seen from FIG. 2 of the present invention, each of the pieces 2 has a side defined by the upper contour a and the lower contour b, and the radius from the center of the sphere 1 is the lower contour. Passes first through (b) and through the upper contour (a).

In another embodiment, when assembling the sphere 1, a portion of the figure may be drawn on each of the pieces 2 so that the individual pieces 2 may provide clues to the user to form the entire sphere 1. Can be.

However, although numerous features and advantages of the present invention are listed along with the structure and function of the invention in the above description, the disclosure herein is by way of example only, and is indicated by terms of broad general meaning particularly expressed in the utility model registration claims. Paper may be arbitrarily altered in detail, in particular in terms of shape, size, and arrangement, within the scope of the basic principles of the present invention throughout its scope.

According to the present invention, the difficulty of assembling the jigsaw toy can be increased not only by the amount of pieces but also by forming and maintaining a three-dimensional spherical jigsaw toy. In addition, there is provided a jigsaw puzzle that has a true three-dimensional effect without using an aid inside the three-dimensional spherical jigsaw puzzle.

Claims (1)

In the three-dimensional spherical jigsaw toy comprising a sphere (1) consisting of a plurality of arcuate pieces (2), Each piece (2) Have a uniform thickness, and A bottom surface partitioned by a lower contour and an upper surface partitioned by an upper contour, An inner radius extending from the center of the sphere to a point on the bottom surface and an outer radius extending from the center of the sphere to a point on the top surface, With projections 3 and cutouts 4, When two adjacent pieces (2) are connected so that there is no gap between two adjacent and connected pieces (2), The projections 3 and cutouts 4 per two adjacent pieces 2 correspond in a complementary fashion, so that the sphere 1 is rebuilt when all pieces are assembled. Fit toy.
