Basically, the notch-shaped groove portion is fitted on the mating plate surface or the notch-shaped groove portion to be joined and assembled. The groove is approximately the same as the thickness of the plate, and it faces from the appropriate center around each side of the polygon of the block or around the circle toward the center of the block. It is set so that there is an optimal fit between the two. Here, the notch-like groove portion is provided with a fine convex portion having an appropriate shape, and the corresponding block plate surface is provided with a fine concave portion corresponding to fitting or the like.

Effect of device

According to the present invention, a plurality of plate-like blocks having substantially the same assembling style can be assembled firmly and firmly without limitation by being orthogonal to each other. As a result, it can be used as an assembled toy that can form various shapes using it for play, educational or puzzle, and it can be applied to interior figurines, displays, furniture, etc. for storing and placing small items. . In principle, the block of the present invention can be molded easily and inexpensively as appropriate by subjecting a block having the same shape to the pressing of a plate material, blow molding or injection molding of a resin material, and mass production is facilitated.

Hereinafter, the present invention will be described with reference to FIGS. FIG. 1 is a front view and a side view of a square block as a typical example of application according to the present invention. FIG. 2 is a view showing an example of an assembled structure in a PP cross section in FIG. 1 in a state where the block is fitted with another block having a different shape.

The present invention is first shown as a square block as an application example. As shown in FIG. 1, the structure mainly includes a block (1), one or more notch-shaped grooves (2) provided on the block, convex portions (3) provided on the side walls of the groove, and the block plate. It is comprised from the recessed part (4) provided in the surface (plate surface). The block (1) is formed of plate-like resin, rubber, wood, paper or cardboard, ceramics, clay, metal, etc. by pressing, compression processing, blow molding processing, injection molding processing, etc., and its shape is viewed from the front. A square. On this plate surface, a notch-shaped groove portion (2) is provided from approximately the center of at least one side toward the center of the surface at a right angle to the width, and the width (dimension d in the figure) is fitted and assembled. Is approximately equal to the thickness of the plate (shown for convenience in dimension D in the figure), and the length (dimension a in the figure) is approximately one-fourth of the length of each side (dimension A in the figure), that is, from each side. It is formed in a shape as shown in FIG. 1 with approximately half (1/2) or less of the length (1/2 of A) toward the center (indicated by O). The XX axis, the YY axis, and the ZZ axis in FIG. 1 are shown for reference showing the object in the vertical, horizontal, and thickness directions of the block (1), respectively.

In the present invention, in order to strengthen the fitting between the blocks, a convex portion (3) as shown in FIG. 1 is provided on the side wall of the groove portion (2) of the block (1) and the concave portion (4) corresponding thereto. ) Is provided on the plate surface of the corresponding block of the assembly partner (in FIG. 1, the same block is used for convenience). This convex part (3) is shown in the example which forms the mountain shape which the side surface is shown in the groove part (2) shown in the right center of the front view. Note that the height of the convex portion such as the height of the peak is actually very small with respect to the width d of the groove portion (2), and is hereinafter referred to as an effective width d, but is exaggerated for the sake of drawing and explanation (the same applies to the concave portion). . The fine concave portion (4) corresponding to the fine convex portion (3) is also formed in a valley shape corresponding to the mountain shape along the side as shown on the right side of the figure. FIG. 2 shows a state in which both are combined. In this case, the block (1) is different from the valley shape on the plate surface as in the PP cross section (right side) of FIG. The chevron shape of the groove part (21) fits each other. Here, the minimum pitch b1 of the mountain shape in FIG. 1 is substantially the same as the minimum pitch b2 of the valley shape, and the number and position of each are appropriately set.

The shape of the fine protrusion (3) described above may be a substantially hemispherical or kamaboko-like columnar shape as shown on the left side of FIG. 1, and the corresponding fine concave portion (4) is as shown on the left side of the figure. A circular depression (dimple) or a raindrop-like semi-cylindrical depression (trench) is provided as described above. In FIG. 2, a circular block 2 (12) with respect to the P-P cross section of FIG. 1 has a fine convex part (3) of the groove part (22) and a fine concave part on the plate surface of the block (1). (4) shows a state where they are fitted and combined with each other.

In the present invention, as described above, the shape of the combination block can be variously polygonal or circular. However, in order to make each block easy to combine with each other, the thickness D is substantially made common so that each block has a common shape. It is preferable that the effective width d of the provided groove is also made common. Further, in FIG. 2, the combination of the blocks is the free position of the plate surface of one block (1) and the corresponding groove 1 (11) or each groove (21) of the block (12) (21) or (22). Although the fitting is shown, it is also possible to fit the groove portions of the two facing each other. In this case, it is easy to obtain a more firm combination in cooperation with the fitting of the fine protrusions (3) and the fine recesses (4) described above.

It should be noted that the arrangement of the convex portion (3) and the concave portion (4) can be fitted to each other even if the former is disposed on the plate surface and the latter is disposed on the side surface of the groove portion (2). Don't worry.

The shape of the fine protrusions (3) and the recesses (4) described above is small in the right half of the right half of FIG. 2, like the fine protrusions (3) on the side wall of the block 1 groove (21). 2 is a combination of a sawtooth-shaped unequal triangular triangle with a large inclination in the opposite direction and a corresponding concave portion (4) on the plate surface of the block (1) having substantially the same shape. In block 1 (11), the resistance in the right direction (the direction of disengagement) with respect to block (1) is larger than that in the opposite left direction (the direction of fitting insertion), and the resistance is large and it is difficult to separate from each other. The effect of the shape of the convex portion (3) and the concave portion (4) can be obtained in the same way by making the side cross-sectional direction asymmetric even in the case of the semicircular sphere or the semicylindrical body.

Also, the convex part (3) and the concave part (4) described above are roughened with a material that is not slippery and fits securely (not shown), or a material having similar characteristics is attached. It may be configured.

The shape of the block is possible as long as it does not differ from the gist of the present invention even if the size or shape of the mating block to be combined or the color or pattern of the mating block is changed by rounding or cornering the corner or notch groove. .

It is the front view and side view of the block of the representative example in connection with this invention. It is an example of an assembly configuration of a plurality of blocks according to the present invention.
