Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to combination blocks used as toys, teaching materials, etc.

Combination blocks are known in which various desired shapes are constructed by combining one or more types of unit blocks and mutually combining parts that form complementary shapes, and the materials used include wood, wood, etc. Those using plastic etc. are well known.

Many of the conventional combination blocks require elastic deformation of the materials when they are assembled or removed, and as a result, there is a high risk of breakage.

Moreover, such solid unit blocks are extremely inconvenient to handle and store due to their shape and volume.

The present invention provides at least three of the above-mentioned conventional combination blocks.
each of the unit blocks having a cross-sectional shape of an H-shape, a single-shape, and a U-shape, each of which is symmetrical with respect to at least one straight line, and at least two slopes that are symmetrically inclined with respect to the straight line; This invention relates to improvements in combination blocks having line portions.

This type of combined block can be easily combined or released by relative movement in the right angle direction with respect to each cross-sectional shape part, and by appropriately determining the arrangement of the inclined line parts, the unit blocks within the cross-sectional shape plane can be easily assembled or released. Relative movement between them can be prevented.

According to the present invention, in the combination block of the above type,
Each unit block includes two or more generally rectangular inner boxes made of paper or other flexible sheet material, and an outer box made of similar sheet material that at least partially covers and connects the inner boxes. The outer box part consists of two parts of the aforementioned H-shape, 1-shape or U-shape of each unit block.
two surfaces connected to these two surfaces, and a tab that is connected to at least two of these four surfaces and has an insertion part that is inserted into a notch hole provided in the inner box. A union block is provided, including:

According to the present invention, it is possible to manufacture and sell combination blocks as an assembly kit, which gives a unique sense of hobby and has the advantage of not taking up much space or bulk when stored or transported.

Embodiments of the invention will now be described with reference to the accompanying drawings.

FIGS. 1 to 4 show four unit blocks A having uniform cross-sectional shapes of an 8-shape, a T-shape, a U-shape, and a T-shape, respectively;
B, 0. Indicates D.

Figure 1 shows a unit block A that is shaped like a figure 8 in the upper and lower 2 and left and right X directions, and its cross-sectional shape is
, Zo is symmetric with respect to Zo.

One of the contour lines defining the four protrusions of the H-shape each has an inclined line portion defined by an inwardly widening inclined surface 1 a y 1 a', and each of the protrusions The wall thickness becomes thinner towards the inside.

All surfaces other than these four surfaces 1 a and 1 a' are X.

It is parallel to any of the three orthogonal planes defined by the Y and Z axes.

FIG. 2 shows a T-shaped unit block B, and among the three protrusions forming the T-shaped cross-sectional shape, the Z-direction protrusion has two symmetrical inclined surfaces 1b.

It has an inclined line portion defined by 1b'.

The cross-sectional shape of the T-shape is symmetrical with respect to the straight line Zo Zo.

Note that block B has a complementary shape with respect to the upper half or lower half of block A, and has surfaces 1a and 2a of block A.
, 3a are arranged to exactly overlap the surfaces 1b, 2b, and 3b of block B, respectively.

FIG. 3 shows a U-shaped unit block C, which is symmetrical about the straight line Zo Zo.

The unit block C has a shape equivalent to that obtained by cutting the unit block A along the straight line Xo Xo.

FIG. 4 shows another unit block D in the shape of a single character.

The line of symmetry is shown as Zo Zo. In this case, the two protrusions in the X direction each have a surface 1d.

A beveled line section defined by 1 d' is provided.

, the unit block D has a shape obtained by cutting the unit block A along the straight line Zo-Zo.

Although the illustrated unit blocks have the same horizontal length in the Y direction, they may also be combined with units having negative lengths in the Y direction.

A combination block composed of unit blocks having the shape shown in the figure is well known, and various modifications thereof are also known.

The present invention relates to an improvement of the combination block of the above-mentioned type, in which each unit block A t B , Ct D has 2
One inner box A-1, one inner box A-2, and one inner box B-
1, B-2, two inner boxes 0-1 and one inner box 0-2, each one inner box D-1, D-2 and each outer box part A-3
, B-3, 0-3, and D-3.

The outer box part A-3 has a surface 4at4 having a figure-8 cross-sectional shape.
a' and surfaces 5a and 5a' connected to both surfaces 4at4a' partially surround the inner boxes A-1 and A-2, and the inner box A
Insert part 9a (
5) have folding tabs 7a, 8a.

Since each unit block is composed of an inner box and an outer box surrounding it, it is easy to manufacture the unit blocks from flexible sheet materials such as paper, and the lack of strength and rigidity can be overcome. It can be supplemented.

Since it can be assembled by folding and inserting flexible sheet materials such as paper, it can be manufactured and sold as an assembly kit, and does not take up much space or bulk when stored or transported.

Details of the outer box portion A-3 and inner boxes A-1 and A-2 as examples of each outer box portion and inner box are shown in FIGS. 5 to 7.

In FIG. 5, the outer box portion A-3 is glued together with a glue allowance E so as to partially cover the inner boxes A-1 and A-2.

Each tab 7ap8a is provided with an insertion portion 9a, which is inserted into the notch hole 6a of the inner box AIPA-2.

Preferably, each insertion portion is inclined as shown in the figure, and a stepped portion S is provided to prevent removal.

Developed views of the inner boxes A-1 and A-2 are shown in FIGS. 6 and 7.

F and F' are folded parts, and although they may all be continued as glue allowances, it is preferable to glue only F' and use the others as folded parts, as this allows each inner box to be folded and stored. .

Outer box parts B-3, C-3, D of unit blocks B, C, D
-3, inner box B-1, B-2, 0-1, 0-2, D-1,
Although the details of D-2 are not shown, it can be easily inferred from the above description of FIGS. 1 and 5-1.

In addition, in Fig. 1, Fig. 2, Fig. 3, and Fig. 4, inner box A
2? The shape arrangement of B 2°0 2tD 2 is shown by broken lines (partially solid lines).

Note that the configuration and arrangement of the inner box, the arrangement of the insertion portion of the outer box, etc. can be changed as appropriate.

As described above, according to the present invention, each unit block is composed of an inner box and an outer box that can be folded, and the insertion portion provides sufficient shape retention, is lightweight, and takes up little space for storage. I never take it.

It is inexpensive because sheets such as paper can be used as the material.
