Description

Chain Block Toys {Toy chain block}

The present invention relates to a chain block toy connected by body recognition by the assembly of a female coupling portion and a male coupling portion, and allows a three-dimensional block assembly having multiple directional coupling directions to be possible with only a straight block.

10, the conventional chain block has a pair of rotation projections 101, which are inserted into both side ends of the male coupling portion 100 having the rotation grooves 101 on both sides thereof and which are inserted into the rotation groove 101, Two coupling pieces 201 and 202 formed on the inner side of the male coupling portion 200 are vertically formed so that the female coupling portion 200 is integrally formed on the opposite side of the male coupling portion 100.

Therefore, in this type of block, the male engaging portion 100 is inserted between the engaging pieces 201 and 202 of the female engaging portion 200 and assembled only by the engaging method. In the assembled state, It is possible to perform the block assembly only in the planar state having the X and Y axes, and it is impossible to assemble the block into the three-dimensional shape having the X, Y and Z axes.

Therefore, in order to assemble the blocks in the three-dimensional shape having the X, Y, and Z axes, as shown in FIGS. 10 to 12, as well as the basic blocks of the straight shape having the joining directions of the X and Y axes, And the male coupling portion 100 and the female coupling portion 200 are formed in different directions in each coupling direction.

However, in order to provide such a type of block, the direction of the mold is different for each block type, and therefore, a separate mold has to be provided.

SUMMARY OF THE INVENTION Accordingly, the present invention has been made to solve the above-mentioned problems occurring in the prior art, and it is an object of the present invention to provide an apparatus and a method for assembling an arm coupling unit, In this case, it is possible to assemble the blocks into three-dimensional shapes having X, Y, and Z axes, so that all three types of blocks can be used to provide all the various conventional stereoscopic blocks.

      Hereinafter, a preferred embodiment of the present invention will be described in detail with reference to the accompanying drawings. First, in describing each drawing, reference numerals for symmetrical parts are omitted.

       As shown in FIGS. 1 to 6, the present invention provides a chain block toy in which a male coupling portion is coupled to an female coupling portion of another block, (1) having an assembling opening (23) having a pivotal hole (22) in which a pivotal protruding frame (11) of a male engaging portion (10) The other blocks 2 and 3 constituted by the arm engaging portion 20 or the male engaging portion 10 formed with the assembling projection 30 to be fitted into the assembling opening 23 of the X-, Y-, and Z- Direction.

       The assembly protrusions 30 are formed only at one side of the arm engagement portion 20 or the male engagement portion 10 and may be provided with various design blocks depending on the shape of the joint surface 31 with the assembly opening portion 23 It is possible.

      Also, in the block of the present invention, there is formed a mortar groove 40 for saving the raw material and preventing deformation of the shape. At this time, the mortar groove 40 is formed in a direction that can be formed simultaneously with the entrance / So that the cost of the mold for making the block can be minimized.

     In other words, the block of the present invention is formed only in the planar structure of the X and Y axes as shown in FIGS. 4 to 6, and is formed by only entering and exiting the mold in the directions of the X and Y axes. The recessed grooves 40 are formed.

     The blocks of the present invention are equally applicable to the protruding rim 12 and the pivoting protruding rim 11 of the male coupling portion 10 for easy coupling and disassembly of the male coupling portion 10 and the female coupling portion 20, Quot; V "grooves 11a are formed in a line, and a latching protrusion 21a is formed at the inner side end of the coupling piece 21 of the female coupling 20 to be engaged with the respective" V " A plurality of "V" grooves 11a formed in the rim 12 of the male engaging portion 10 are formed at a predetermined angle to form the male engaging portion 10 and the female engaging portion 20, So that the rotation angle can be controlled.

       Various types of reinforcing fins can be formed on the inner surface of the assembly opening 22 or on the outer surface of the assembling and protruding surface 30 in order to prevent the assembling protrusion 30 from being dislodged from the assembling opening 22.

       The pivoting protrusion 11 of the male coupling portion 10 should have an inner wall 22b of a thickness not protruding through the pivot hole 22a in the pivot hole 22a of the assembly opening 22 This is because when the pivoting protrusion 11 protrudes through the pivot hole 22a, the assembling protrusion 30 is less fitted to the assembly opening 22 by the protruded height, Because it can be easily separated.

       Therefore, in the block of the present invention, the assembling opening portion 22 is formed outside the engaging piece 21 of the female engaging portion 20 so that the assembling protruding portion 30 is fitted, so that the planar structure having the engaging means in the X and Y axes A block assembly of a three-dimensional structure having a coupling means in the Z-axis in the block becomes possible.

      Therefore, the block of the present invention has the male engaging portion 10 having the assembling protrusion 30 only on one side of the block 1 composed of the female engaging portion 10 and male engaging portion 20 as shown in Fig. It is possible to assemble into a three-dimensional structure of the same type as that of the conventional block of "C" shape as shown in Fig. 11, 12, it is possible to assemble the block 3 in the same manner as the conventional block of the " L "-shaped shape as shown in FIG. 12, The block 3 of the male engaging portion is connected to the one side and the block 2 of the female engaging portion is coupled to the other side of the other side. As a result, It is possible to assemble in the same shape as the block, and also, as shown in Fig. 8, If it is possible to assemble the block having a number of engagement means in one direction.

       Therefore, according to the above-described coupling method, block assembly to any three-dimensional structure that has been provided in the past can be performed.

       Therefore, since the block of the present invention can provide a block having a three-dimensional structure in any form consisting of X, Y, and Z axes with only three types of blocks, it is necessary to provide each block according to the shape of a block having a three- The quantity of the mold can be greatly reduced.
