BACKGROUND OF THE DISCLOSURE Field of the Disclosure

The present disclosure relates to a self-assembly block toy set and, more particularly, to a self-assembly block toy set in which each block interlocks with each other laterally, at right angles along the side of each of the blocks, vertically or in other various ways, thereby being assembled into diverse models.

Description of the Related Art

A block toy refers to a toy with which one could construct a solid shape they desire by assembling small blocks made typically of plastic so that users relish the shape while such a block toy includes a plurality of, and a set of, the blocks.

Self-assembly toys, as a kind of block toys, have been marketed for which it is required to interlock the protuberances and slots configured in each block to complete the toy. As for such an self-assembly toy, it is, however, also required to forcefully plug each protuberance into each slot corresponding to the protuberance in each block and, even after the assembly is completed, it is not very easy to disassemble the blocks to construct another solid shape.

Those block toys which include blocks with magnets embedded inside have also been marketed so that the blocks are easily assembled by means of magnetism when brought proximately to each other. As for such a block toy with magnets, although it is convenient to assemble the blocks with each other by means of magnetism and also convenient to disassemble after the assembly is completed, the shape could collapse with a rather slight impact because, in most cases, the edges of the blocks are rounded and, correspondingly, binding between the blocks is not firm.

Although they are currently developing those block toys which have interlocking units of a variety of shapes, instead of having an interlocking structure in which protuberances and slots formed in each of the blocks fit into each other, in order to provide convenience of assembling and firmness of binding force between the blocks, it is still necessary to develop a self-assembly block toy set in which each block interlocks with each other laterally, at right angles along the side of each of the blocks, vertically or in other various ways to the extent possible so as to nurture creativity of those children who use such block toys.

The above information disclosed in this Background section is only for enhancement of understanding of the background of the invention and it may therefore contain information that does not form the prior art that is already known to a person of ordinary skill in the art.

a straight line slot 180 that is elongated inside the main body unit 110 along the edge of the main body unit 110 on the top surface and the bottom surface of the main body unit 110.

The first interlocking unit 120 includes:

a II-shaped interlocking tip 121, whose leaves are extended in a symmetrical way with a gap in between so that the second interlocking unit 130 of the other one of the square blocks 100 could be inserted thereinto;

slots 122 that are formed in a symmetrical way on the inner wall of the II-shaped interlocking tip 121; and

protuberances 123 that are formed in a symmetrical way on the outer wall of the II-shaped interlocking tip 121.

In addition, the second interlocking unit 130 includes:

an H-shaped interlocking tip 131 that could be inserted into the first interlocking unit 120 of the other one of the square blocks 100; and

Meanwhile, the first interlocking unit 120 and the second interlocking unit 130 of one of the square blocks 100 interlocks with the second interlocking unit 130 and the first interlocking unit 120, respectively, of the other one of the square blocks 100 so that the other square block could rotate on the slot 122 and the protuberance 132 when the protuberance 132 of the second interlocking unit 130 is inserted in the slot 122 of the first interlocking unit 120.

The vertical interlocking protuberances 140 are a plurality of small cylindrical protuberances that are arranged in a symmetrical way and extended from the top surface of the main body unit 110 at the center of the top surface while the vertical interlocking slots 150 are a plurality of small cylindrical slots arranged in a symmetrical way and depressed from the bottom surface of the main body unit 110 at the center of the bottom surface so that the vertical interlocking protuberances 140 of the other one of the square blocks 100 could fit thereinto.

The cross axis inserting hole 160 assumes the shape of a cross or a cylinder when it is formed at the center of the main body unit 110. A cross axis 400, separate from the square block 100, is inserted into the cross axis inserting hole 160. If the cross axis inserting hole 160 forms a cross, the cross axis 400 rotates together with the square block 100 when the cross axis 400 is inserted into the cross axis inserting hole 160 and rotates while if the cross axis inserting hole 160 forms a cylinder, only the cross axis 400 rotates and the square block 100 does not even when the cross axis 400 is inserted into the cross axis inserting hole 160 and rotates.

The interlocking unit inserting holes 170 formed in the main body unit 110 save for the cross axis inserting hole 160 have a structure into which the interlocking tip 121 of the first interlocking unit 120 and the interlocking tip 131 of the second interlocking unit 130 of the other one of the square blocks 100 could be inserted at right angles and include a plurality of square inserting holes 171 into which the interlocking tip 121 of the first interlocking unit 120 of the other one of the square blocks 100 could be inserted and a plurality of X-shaped inserting holes 172 into which the interlocking tip 131 of the second interlocking unit 130 of the other one of the square blocks 100 could be inserted.

Three of the interlocking unit inserting holes 170 could be aligned above the cross axis inserting hole 160, each one, on the left and right, respectively, of the cross axis inserting hole 160 and three, beneath the cross axis inserting hole 160, thereby forming a grid while the first interlocking unit 120 and the second interlocking unit 130 of the other one of the square blocks 100 could be inserted, in six modes, into the grid-formed interlocking unit inserting holes 170. (Refer to FIG. 15.)

The interlocking unit inserting hole 170 could have an inserting slot 173 on its top, bottom, left and right side, respectively, so that the first interlocking unit 120 and the second interlocking unit 130 of the other one of the square blocks 100 are easily inserted into and elastically combined with the interlocking unit inserting hole 170.

The main body unit 110 includes, at the center of the outer surface of each side thereof, a third interlocking unit 190 which has an interlocking tip 191, whose two leaves are extended in a symmetrical way with a gap in between so that a side of the main body unit 110 of another square block 100 could be inserted thereinto at right angles, wherein the interlocking tip 191 of the third interlocking unit 190 is shorter than the interlocking tip 121, 131 of the first and second interlocking unit 120, 130 and has protuberances 192 on its inner surface, wherein one of the protuberances 192 is formed in the top portion of the inner surface while the other is formed in the bottom portion of the inner surface.

When a side of the main body unit 110 of one of the square blocks 100 interlocks orthogonally with a side of the main body unit 110 of the other one of the square blocks 100, one of the the protuberances 192 formed on the inner surface of the interlocking tip 191 of the third interlocking unit 190 of the one square block 100 is inserted into the side surface orthogonal interlocking slot 181 of the top surface of the main body unit 110 of the other square block 100 while the other protuberance 192 is inserted into the side surface orthogonal interlocking slot 181 of the bottom surface of the main body unit 110 of the other of the square block 100. Therefore, the sides stably interlock with each other at right angles at the center of the side between the square blocks 100.

The cross axis inserting hole 260 assumes the shape of a cross or a cylinder when it is formed at the center of the main body unit 210. A cross axis 400, separate from the pentagonal block 200, is inserted into the cross axis inserting hole 260. If the cross axis inserting hole 260 forms a cross, the cross axis 400 rotates together with the pentagonal block 200 when the cross axis 400 is inserted into the cross axis inserting hole 260 and rotates while if the cross axis inserting hole 260 forms a cylinder, only the cross axis 400 rotates and the pentagonal block 200 does not even when the cross axis 400 is inserted into the cross axis inserting hole 260 and rotates. (Refer to FIG. 3.)
