  The material used in the present embodiment is that the outer peripheral surface portion 11 of the cylindrical convex portion 10 and the protrusion 22 of the polygonal columnar concave portion 20 are appropriately elastically deformed when the cylindrical convex portion 10 is fitted to and removed from the polygonal columnar concave portion 20. In addition, when the protrusion 22 of the polygonal columnar recess 20 is engaged with the circumferential groove 12 of the cylindrical protrusion 10, it has flexibility and rigidity that cannot be removed without a certain level of force. Any material may be used as long as it is, but polyurethane that is easy to handle and lightweight is preferable, and polyurethane foam is particularly preferable.

  Hereinafter, the process of manufacturing with foamed polyurethane will be described.

  A process of manufacturing the assembly block 1 shown in FIGS. 1 to 8 will be briefly described.

  A molding die 100 of the assembly block 1 shown in FIGS. 31 to 33 includes an upper die 101 and a lower die 105. On the lower surface of the upper die 101, one surface portion 4 and the other surface portion of the assembly block 1 are provided. 5. One side surface portion 6, the other side surface portion 7, and the outer peripheral surface portion 11 of the cylindrical convex portion 10, the same dimension and the same shape as the circumferential groove 12, and a recessed female molding surface 102 having the same shape are formed. On the upper surface of 105, the inner peripheral surface portion 21, the ridge 22, the top surface portion 24, the inclined notch surface 25, the cylindrical concave portion 26, the top surface portion 27, the inner peripheral surface of the polygonal columnar recess 20 in the assembly block 1 A protruding male molding surface 106 having the same dimensions and the same shape as the portion 28 and the joining edge portion 29 is formed.

  First, a mold release agent is applied to the molding surface 102 of the upper mold 101 and the molding surface 106 of the lower mold 105, and then a paint is sprayed to coat the molding surface 102 and the molding surface 106 with a thickness of 5 to 50 μm. The main raw material mixed in a resin mixer (not shown), for example, after proceeding to the coating film drying process for drying the coating film after finishing the coating film forming process for forming a 5 to 10 μm coating film, Then, a foaming agent such as chlorofluorocarbon and water, a catalyst for promoting foaming, and a foam stabilizer are mixed in the mixture of polyisocyanate and polyol, and the mixture is injected into the concave molding surface 102 of the upper mold 101.

  Thereafter, the lower mold 105 is lowered from above to the mating surface 103 of the upper mold 101 into which the front and rear mixture has been injected, and the mating surface 107 of the lower mold 105 is brought into intimate contact with the mating surface 103 of the upper mold 101. After filling the space 110 in the space 100 with the mixture, performing foaming treatment in the mold 100, and then curing, separating the mating surface 103 of the upper mold 101 and the mating surface 107 of the lower mold 105. After removing the assembly block 1 from the upper mold 101 or the lower mold 105, the assembly block 1 can be manufactured by cutting off the excess portion protruding from the upper mold 101 and the lower mold 105.

  In the manufacturing process, before the coating film forming process, after forming a skin by closely attaching a thin sheet of heat-welding to the molding surface 102 and the molding surface 106 of the upper mold 101 and the lower mold 105, After the foaming process is performed, a manufacturing method is performed such as heating the mold 100 and performing a skin fusion process in which the internal polyurethane foam is in close contact with the heat-welding transparent skin. You may do it.

  Moreover, you may abbreviate | omit a coating-film formation process, or may perform a coating-film formation process (in-mold coating) after a hardening process.

  In the assembly block 1 manufactured as described above, the foam of the assembly block 1 is soft, and the assembly block 1 is dropped on the infant's foot or the infant collides with the assembly block 1. However, there is no risk that the infant will be injured.

  In addition, the coating layer or skin of the assembly block 1 is smooth, but is harder than the foam inside, so the ridge 22 with a large surface area is harder than other foam parts. When the protrusion 22 of the polygonal column-shaped recess 20 is engaged with the circumferential groove 12 of the cylindrical protrusion 10, the protrusion 22 is not missing, has a certain degree of engagement holding capability, and is slightly The engagement between the circumferential groove 12 and the ridge 22 is not released by a simple force.

  The assembly block 1 having a total of eight cylindrical protrusions 10 in four rows and two rows in one row shown in FIG. 1 to FIG. 8 is configured as described above. Without shifting the position, the other assembly block 1 is lowered from directly above one assembly block 1, and the opening of the cylindrical convex portion 10 of one assembly block 1 is changed to the polygon of the other assembly block 1.

The foam assembly block 1 is softer than a conventional hard synthetic resin assembly block, and can be assembled. Even if it is an infant, this can be performed for the coupling | bonding and isolation | separation of the blocks 1 for mutual use.

  Furthermore, since the protrusion 22 of the polygonal columnar recess 20 has a large surface area, it is partially harder and more durable than the other parts. Therefore, the protrusion 22 is missing when the lower mold 105 is removed. In addition, even if the assembly blocks 1 are repeatedly coupled and separated, the protrusions 22 are not easily lost, and the durability is high.
