Solid puzzle block

Abstract

Provided is a solid puzzle block (1). The solid puzzle block has a connecting groove (13 and 33) open from the top to the bottom of a side surface (11 and 31) of its main body to allow cross-connecting of two blocks, and a connecting peg (14) and connecting hole (15) formed at either end of the connecting groove (13) on the side surface (11 and 31) to allow side-connecting of two blocks. In order to impart a firm cross-connection, a plurality of embossings (12) are formed on the left and right surfaces of the connecting groove (13 and 33) and the contact portions (42) of the upper and lower surfaces (40 and 41) contacting the connecting groove (13 and 33). At an end surface (16 and 36) between the left and right surfaces of the connecting groove (13 and 33) is fixed a connector (17), to which an operating unit (21) located inside the main body is connected electrically. Although the firmly connecting block is not of an assorted variety, it can arouse enjoyment and curiosity in users of all ages.

Description

TECHNICAL FIELD [0001] The present invention relates to a solid puzzle block, and more particularly, to a solid puzzle block capable of side-connecting, cross-connecting, and connecting in a variety of ways. BACKGROUND ART [0002] Solid puzzle blocks come in many varieties and are generally used for developing intelligence and curiosity in babies. Because they lack connectors, solid puzzle blocks may be combined into a desired shape only by placing them side-by-side or stacking them one on top of another. [0003]FIG. 1 is a perspective view of separated puzzle blocks of the prior art, and FIG. 2 is a perspective view of connected puzzle blocks of the prior art. FIGS. 1 and 2 will hereinafter be explained. [0004] Puzzle blocks (A) of the prior art were developed to offer a 3-dimensional alternative to 2-dimensional picture puzzles. Regarding the structure and principles of such puzzle blocks, puzzle blocks come in a variety of polyhedral forms, where each surface of a polyhedron is pai...

Benefits of technology

[0010] The solid puzzle block of the present invention may be side-connected to another block by means of the connecting peg and connecting hole, and firmly cross-connected to another block in a variety of ways by means of an embossed connecting groove and contacting portion. The solid puzzle block has a built-in light or sound-emitting device that operates when blocks are cross-connected, inducing amusement and curiosity and appealing to all age groups. Furthermore, due to its simple structure, manufacturing cost is also reduced.

Problems solved by technology

Accordingly, there is a limit to the types of shapes that may be formed, and puzzle blocks (A) forming shapes may easily be dislodged from one another, so that a completed form is difficult to preserve intact for display purposes.

Also, a set of puzzle blocks (A) often consists of about 100 differently shaped blocks to form a variety of shapes, thereby increasing the manufacturing cost of die-casting.
