Description

pieces of puzzle

Technical field

The invention is a puzzle toy, in particular, pieces that can be assembled together to form an irregular curved surface puzzle.

Background technique

The existing art has hollow puzzles with curved surfaces, such as spherical puzzles, which have multiple pieces with the same shape, structure and thickness. Each piece can be assembled into a sphere without the use of adhesives or supports between the pieces. , the pieces have shapes that can be combined with each other and have a curved surface centered on the center of the sphere. The curved surface of the pieces is the same as the curvature of the surface of the assembled sphere. When the pieces are assembled to form a sphere, , in order to ensure that adjacent pieces can be combined with each other without falling off at will, the combination structure used is to provide multiple protrusions and multiple concave seats around each piece, and each protrusion is respectively Protrudingly arranged around the piece, each concave seat is concavely arranged around the piece. The concave seat and the protruding head are located around the piece and staggered. Two adjacent pieces use the concave seat of one piece to connect with the other one. The convex heads of the pieces are complementary to each other, and the adjacent pieces are assembled with each other with a convex head and concave seat structure to form a spherical puzzle with a curved surface shape.

The piece is a quadrilateral piece, and the convex head protrudes outward from the periphery of the piece body. A necking portion is formed between the convex body of the convex head and the piece body. The lateral distance of the necking portion is smaller than the lateral distance of the surface of the convex head. A fitting opening is formed by the concave seat around the periphery of the piece body. The shape of the fitting opening corresponds to the necking portion. The side curved surface formed by the peripheral edge lines of the piece body, the protruding head and the recessed seat, and the two adjacent pieces. When assembling, the convex body of the convex head of one piece and its necked part are accommodated with the fitting opening of the concave seat of the other piece, and the side curved surfaces of the two adjacent pieces are in contact with each other, and the side curved surfaces face The imaginary extension surface of the center of the ball passes through the center of the ball. The arc length of the concave seat of each piece on the outer surface is greater than the arc length on the inner surface. In the early stages of assembly, the user's hands have more space to move adjacent pieces together. The pieces are assembled and arranged so that the fastening position is accurate and the external curved surface is flat. However, when the last few pieces are assembled, there is no adequate space for the fingers to operate, so the pieces can only be directed towards the prototype of the sphere. The remaining gaps are placed into the assembly. At this time, due to the interference and overlap of the side curved surfaces between the necking part of the convex head and the fitting opening of the recess, it is more inconvenient to assemble the last few pieces, and even makes it difficult to assemble the last few pieces. The last piece cannot be assembled if excessive pressure is applied or it may cause problems and shortcomings such as collapse or separation of the entire sphere.
