Description

[Detailed description of the invention] (Industrial field) The present invention belongs to the field of educational toys, and specifically relates to an educational toy that connects prismatic cylindrical columns, and its purpose is to The letters, numbers, pictures, etc. expressed on the square cylinder surface of the cylinder can be arranged by arbitrarily combining or separating the pentagonal cylinder and further rotating the combination. The idea is to vary the movements by changing them or matching the picture patterns, so that young children can learn them with interest.

(Prior art) Traditionally, as an educational toy for young children, the traditional
A piece of board about m square and about IC7F+ in thickness with pictures or letters displayed by branding, silk printing, etc., or a cubic block with a circular convex part and a circular concave part connected to each other, and a triangular tube attached to this. For example, a cube block with a square convex surface on three sides and a square convex surface on three sides, and a cube block with a square convex surface on three sides,
Some had square concave surfaces and displayed letters, numbers, etc. on these surfaces so that the convex and concave surfaces were connected.

(Problem to be solved by the invention) In the first of the above conventional methods, the child simply selects from among many and arranges or stacks them; Although it is possible to select and assemble the blocks, it is not possible to represent each row of hiragana on the same circumferential surface of one block, and it is not possible to reliably stop when each surface coincides. , in the third one, each side can be matched and connected, but this one can be expressed in the same way as the second one, for example, each row of hiragana is represented on the same circumferential surface of one block. The blocks cannot be rotated while connected.

(Means for solving the problems) The present invention was devised in view of these points, and is a pentagonal cylindrical column expressing letters, numbers, pictures, etc., with a snap mechanism of unevenness on the end surface. By connecting them to each other and making them rotatable so that they can be stopped when the rectangular cylindrical surfaces coincide, the drawbacks of the conventional system are overcome and children can learn letters, numbers, picture patterns, etc. with interest. This is what I did.

(Example) Hereinafter, embodiments of the present invention will be described with reference to the drawings.

The pentagonal cylindrical column A may be solid to function as a toy, but it is better to make it hollow to reduce material costs and to avoid handling hazards by young children. Bottom hollow cylinder 1
and M2, which are fixed together to form a hollow body.

The hollow body 1 and the lid 2 are both plastic molded products, and in the pentagonal cylindrical column A formed as a hollow body, the bottom surface and the lid 2 are both called end surfaces.

The hollow body 1 has a rectangular cylindrical surface 3. 4.5.6.7 and a bottom surface 8, the rectangular cylinder surface is, for example, a square with 5CrIL angles, and the bottom surface 8 is a regular pentagon.

The bottom surface 8 has an outwardly disc-shaped convex portion 9, and the root of this convex portion 9 is a concave groove 10 forming an engaging peripheral portion 11. Square cylinder surface 3. 4. 5.
6. There is a protrusion 12 at a position corresponding to 7.

Further, a stepped portion 13 is formed at the opening of the hollow cylinder 1.

The lid 2 has a regular pentagonal plate 14 with the same thickness as the hollow cylinder 1, and the plate 14 has a circular plate in the center of the plate 14, which is large enough to fit the convex portion 9 of the bottom surface 8. A recessed portion 15 is formed, and indentations 17 are further formed in the peripheral wall 16 of the recessed portion 15 at positions corresponding to each side of the pentagon in the direction of the edge.

A U-shaped elastic piece 19 protrudes inward from the indented wall 18 in the indented part 17, and the front surface of this elastic piece 19 coincides with the surface of the peripheral wall 16. There are two protrusions 20, 20, and a recess 21 is formed between them.

M2 having such a structure is fitted and fixed to the step part 13 of the hollow cylinder 1 with the periphery of the plate body 14, and the hollow 5
A prismatic cylindrical column A (FIG. 7) is formed.

The lid 2' shown in FIG. 4 has a concave portion 15 of the lid 2 shown in FIG.
A projecting wall 16' is provided independently from the outer peripheral wall 22 in order to provide elasticity to a portion corresponding to the peripheral wall 16 of the bottom plate 8 to facilitate fitting of the convex portion 9 of the bottom plate 8. Side 19
' is provided to protrude from the outer peripheral wall 22, its front surface coincides with the front surface of the protruding wall 16', and the front surface of the elastic piece 19' is
The presence of two protrusions 20', 20' and a recess 21' between them is the same as in the case of the lid 2 shown in FIG.

In order to connect a plurality of pentagonal cylinder columns A formed by fixing the hollow cylinder 1 and the lid 2 [or lid 2'], the bottom plate 8 of the pentagonal cylinder column A, that is, the convex end surface. Part 9,
It fits into the lid 2 [or lid 2'] of another pentagonal cylindrical column A, that is, the recessed part 15 on the end surface. The protrusions 20, 20 are pushed along the peripheral wall 16 and resist the elasticity of the elastic piece 19.
By going beyond this, the protrusions 20, 20 fall into and engage with the groove 10.

The two engaged pentagonal cylindrical columns A, A are rotated by the convex part 9 and the concave part 15 of the joint part, but the mutual prismatic surfaces of the pentagonal cylindrical columns A, A are When they match, the protrusion 12 in the groove 10 overcomes the elasticity of the elastic piece 19, overcomes the protrusion 20, fits into the four parts 21 between the protrusions 20 and 20, and stops, and the pentagonal cylindrical columns A and A A long pentagonal cylindrical column with matching square cylinder surfaces is created.

(Effects of the invention) As explained above, the pentagonal cylindrical column connected educational toy of the present invention can be used by appropriately combining and separating the pentagonal cylindrical columns, or by rotating them in a connected state so that the prismatic cylinder surfaces coincide with each other. Because it is constructed so that it can be stopped reliably when the building blocks are stopped, when used by young children, it requires separate movements of joining and rotating, compared to conventional educational toys that are made up of building blocks in pieces. Children can learn letters, numbers, pictures, etc. with interest while playing.

In particular, since the present invention is a pentagonal cylindrical column, it is possible to express each line of characters, such as the ``a'' line and °゛ ``line'' of 5@, on the prismatic cylinder surface. Sound, 1 mocking sound 45 sounds, 1
The hat can express all 71 sounds of hiragana, including voiced sounds, semi-voiced sounds, and cursive sounds, and 75 sounds of hiragana, including 18 sounds and consonant sounds, so young children can learn kana characters with interest. can.

In addition, since the rear pieces can be combined to form a single columnar shape, there is no risk of them falling apart and being lost, making the toy highly functional and valuable as an educational toy.
