Description

[Detailed explanation of the invention] This invention connects unit solids horizontally or stacks them upwards to form a row or stacked solid, and colors, patterns, figures, etc. applied to the outer peripheral surface of the unit solids.
This invention relates to a connecting device for three-dimensional puzzle toys that can be arranged in a free creative arrangement or in a predetermined correct arrangement.

This idea was made for the purpose of increasing the durability of the coupling device and reducing the cost. That is, since puzzle toys are used over and over again, they are required to be particularly robust, and since the toy has a large number of parts, the cost must be low.

Therefore, the present invention has been devised in view of the above points, and will be explained below with reference to the drawings showing the invention as an embodiment.

Figures 1 to 4 show the case where unit cubes 1 formed into cubes are connected, and the unit cubes 1 have narrow long holes 3 in their ridges 2 and bearing cavities 4 in their respective ends. , 4 are left open, and a connecting plate 5 is inserted into this elongated hole 3 to connect the unit cubes 1 to each other.

As shown in FIG. 5, the unit cube 1 is formed from a bottomed box-shaped main body 1a and a lid plate 1b,
The main body 1a has a fitting stepped portion _1a2 formed at the upper edge of its opening, and a cutout _1a1 is formed by cutting out one side of the fitting step _1a2 . The lid portion 1b is formed to fit into the fitting step portion 1a ₂ of the main body 1a to close the opening, and one side of the side wall 1b ₁ has bearing walls 1b ₂ and 1b of a required width on both sides, respectively. ₂ , a band-shaped notch _1b4 is formed into the top plate portion _1b3 with an appropriate width. Thus, the lid plate 1 is attached to the lid body 1a to the main body 1a.
b are fitted and fixed to form the unit cube 1,
Band-shaped notch 1 of cover plate 1b is attached to notch 1a ₁ of main body 1a.
A long hole 3 is formed by matching b ₄ , a connecting plate 5 is inserted into the long hole 3, and protruding shafts 6, 6 formed protruding in an H shape are attached to both ends of the long hole 3, respectively. The unit cube 1 is connected by being engaged with bearing cavities 4, 4 formed in the bearing cavities 4, 4.

Figure 1 shows a case where two unit cubes 1 are connected, but three or more unit cubes 1 may be connected in a line, in an L shape as shown in Figure 7, or in any other direction. . If they are connected by gluing as shown in FIG. 7, the shape of the aggregated unit cube is limited to an L shape, but by connecting the unit cubes with the connecting plate 5, the connecting surface can be varied. For example, in a block puzzle toy that is stacked together, it is possible to make the stacking even more difficult and provide a more interesting toy.Also, since the ridge is formed into a long hole, both sides are cut out in the shape of a groove, and the connecting plate is By inserting the thickness of the plate and bringing the connecting surfaces into close contact, the connection can be made in the same way as with conventional gluing.Also, since the connecting part is attached to the connecting plate, the connecting plate can be inserted in the process of fitting the main body and the lid plate. Since the connecting plate only needs to be attached, assembly is easy and inexpensive, and since the connecting plate is made of a metal plate, it can withstand repeated bending.
In addition, 3D is not limited to cubes,
Of course, a triangular shape as shown in FIG. 8 and others can also be used.

Claims (1)

[Scope of utility model registration request] A plurality of unit solids of an appropriate shape, such as a unit cube formed in a cubic shape, are connected horizontally or vertically at their ridges, and coloring, patterns, figures, etc. are freely applied to the outer peripheral surface of each unit solid. In a three-dimensional connected puzzle toy that is arranged or arranged in a predetermined arrangement, each unit solid is formed from a box-shaped body with a bottom and a lid plate that fits into the opening of the body, and the body has an upper edge of the opening. A fitting step is formed in the body, one side of which is cut out, and the cover plate has a band-shaped notch in which a long hole is formed corresponding to the notch when the fitting step of the main body is fitted. , a bearing wall of the required width is left on one side of the side wall at both ends thereof, and is formed by recessing the appropriate width into the top plate part, and thus,
A three-dimensional connected puzzle toy in which a lid plate is fitted to the main body to form a unit solid, and the unit solids are connected by locking a connecting plate having H-shaped protruding shafts at both ends in the long holes of the body. coupling device.
