It is a corrugated sheet paper, a groove and a writing surface.

Next, the structure of another type of block toy in which cylindrical members are arranged and fixed will be described by taking the block toy 5 of FIG. 1 as an example. As shown in FIGS. 4 and 5, the block toy 5 includes a projecting member 21, a cylindrical member 22, and a covering sheet portion 23.
1, the cylindrical member 22 and the covering sheet portion 23 are made of the same paper as the corrugated sheet paper in which the concave lines and the convex lines are alternately formed on the surface used for the block toy 2 and the like, respectively. It is made by appropriately winding a paper and pasting it with an adhesive so as to keep the wound state. As shown in FIG. 5, the protruding member 21 has the surface of the corrugated sheet paper on which the concave and convex lines are formed facing outward, and
The concave stripes and the convex stripes are wound in the length direction of the protruding member 21. Further, the cylindrical member 22 faces the inside of the protruding member 21 on the surface of the corrugated sheet paper on which the concave and convex lines are formed, and the concave and convex lines are arranged in the longitudinal direction of the cylindrical member 22. Is wound towards. This protruding member 21,
The cylindrical member 22 is made of corrugated sheet paper having the same width.
Both of the cylindrical members 22 have a length, and the protruding member 21 and the cylindrical member 22 are arranged so as to be displaced in the length direction,
The concave line and the convex line on the outer circumference of the projecting member 21 and the inner circumference of the cylindrical member 22 are fitted and fixed by an adhesive. For this reason, a protruding portion 25 as shown in FIGS. 4 and 5 is formed above the cylindrical portion 24 formed by the protruding member 21 and the cylindrical member 22, and below the cylindrical portion, as shown in FIG. A concave portion 26 as shown in is formed. The diameter of the projecting member 21 is the groove 15 formed on the outer periphery of the block toys 2, 3 and 4 which is one type of block toy described above.
Is almost the same as the width of. The three cylindrical portions 24 thus formed are linearly arranged in parallel with their length directions parallel to each other, and the covering sheet portion 23 is provided outside the three cylindrical portions 24.

As described above, the covering sheet 23 is also made of corrugated sheet paper and is wound with the surface thereof facing outward. The concave and convex lines formed on the surface are in the longitudinal direction of the cylindrical portion 24. Is oriented in the same direction as.

Since the block toy 5 is constructed as described above, the diameter of the protruding portion 25 and the inner diameter of the recess 26 of the block toy 5 are substantially the same. Further, the outer circumference of the protrusion 25 and the inner circumference of the recess 26 both show the surface of the corrugated sheet paper. For this reason, when there are two block toys 5, as will be described later, by inserting the protrusion 25 of another block toy into the recess 26 of one block toy 5, the protrusion 25 and the recess are formed. These two block toys can be combined and connected by the fact that the diameters of 26 are substantially the same and the concave and convex lines of the corrugated sheet paper fit together. Furthermore, as will be described later, this block toy can be connected. The protruding portion 25 of the toy 5 can be combined with and connected to the concave groove 15 of the block toys 2, 3 and 4 described above.

Other types of block toys having a plurality of cylindrical portions, such as the block toy 5 as an example, are not limited to the shape shown here. That is, although the block toy 5 is provided with three cylindrical portions 24, although not shown here, the number of the cylindrical portions 24 may be one, two, or four or more. Further, in this block toy 5, both the protruding member 21 and the cylindrical member 22 are formed by rolling corrugated sheet paper having the same width, so that a protruding portion is formed at one end and a concave portion is formed at the other end. However, as in the block toy 76 shown in FIG. 1, by making the inner cylindrical portion longer than the outer cylindrical portion,
It is possible to make a block toy having protrusions formed at both ends, or, although not shown here, the protrusion member 21.
By making the length shorter than the cylindrical member 22, it is possible to create a block toy in which concave portions are formed at both ends.
Although not shown here, in this block toy 5, the cylindrical portions 24 are arranged in a straight line, but the cylindrical portions 24 may be arranged and fixed on the bending line. In addition, the covering sheet portion 23, the cylindrical portion 24, the protruding portion 25, and the concave portion 26 that constitute the block toy 5 described above.
Are a covering sheet portion, a cylindrical member, a protruding portion and a concave portion which respectively constitute the present invention.

The ridges and ridges of the wavy sheet paper 47 attached to the other plate portion 44 of the block toy 41 are fitted to each other, and the wavy sheet paper 37 attached to the other plate portion 34 of each block toy 31 and , The concave stripes and the convex stripes of the corrugated sheet paper 47 attached to the other plate portion 44 of the block toy 41 are fitted (note that the corrugated sheet paper 36, 37, 46, 47, 48 is thick in FIG. 7). It is shown as the one without.) Further, by performing this insertion, the corrugated sheet paper attached to one plate portion 33 of each block toy 31 as shown in FIG. 7B which is a sectional view taken along the line BB in FIG. 36, and the ridges and ridges of the corrugated sheet paper 48 attached to the intermediate plate portion 45 of the block toy 41 are fitted together. In this way, the block toys 31, 41 are connected to each other so that they can be attached and detached at the same time because the friction faces of the multiple concave and convex lines contact each other in the insertion direction thereof, and at the same time, the block toys 31 In the shearing direction of the connection of the grooves 41, 41, that is, in the length direction of the concave groove, a large number of concave lines and convex lines fit with each other, so that they can be firmly connected.

Next, the case of assembling and connecting one type of block toy with another type of block toy will be described with reference to FIG. 8 by taking the block toys 41 and 51 as an example. This connection is performed by inserting the protrusion of the protrusion 54 of the block toy 51 into the groove 42 of the block toy 41. By doing this insertion,
As shown in FIG. 9 which is a sectional view taken along the line CC in FIG. 8, a corrugated sheet paper 46 attached to one plate portion 43 of the block toy 41 and a corrugated sheet attached to the other plate portion 44. The paper 47 and the concave and convex ridges of the projecting portion 54 made of the corrugated sheet paper of the block toy 51 are fitted (note that the corrugated sheet paper 46, 47 and the corrugated sheet paper forming the projecting portion 54 are shown in FIG. 9). Is shown as having no thickness.). In this way, the block toys 31, 41 are connected to each other in a detachable manner because the friction surfaces of the concave and convex lines are in contact with each other in the insertion direction thereof.

In the case where other types of block toys and other types of block toys are assembled and connected, although not shown, they are formed by the inner cylindrical portion of one of the other types of block toys. By inserting the protrusion into the recess formed by the outer cylindrical portion of the other type of block toy, the diameter of the protrusion of the block toy 5 and the inner diameter of the recess are made substantially the same. Since the outer periphery of the protrusion and the inner periphery of the recess both show the surface of the corrugated sheet paper, these two block toys can be combined and connected.

As described above, according to the block toy or the block toy set according to the present embodiment, block toys having various shapes are produced, such as a block toy in which plates are combined and a block toy in which cylinders are combined. However, these block toys can be assembled and connected in any shape. For example, the block toys 2, 3, described above
When 4, 5 are created, these can be assembled as desired, as shown in FIG. Furthermore, by adding other components to one type of block toy that combines the above-mentioned plates,
It is possible to create block toys with more varied shapes. For example, the block toy 61 shown in FIG. 11 is composed of one plate body 62, the other plate body 63 and an intermediate plate body 64, through which the one plate body 62, the other plate body 63 and the intermediate plate body 64 are penetrated.
