본 고안은 인체에 무해한 EVA(Ethylene Vinyl Acetate Copolymer)를 이용하여 각종 다면체로 이루어진 탄성공을 제작하여 코스트를 획기적으로 절감함은 물론 유아의 창의력, 도형에 대한 이해력 등을 증진시킬 수 있도록 하는 유아 지능계발용 다면체 탄성공에 관한 것이다.The present invention is designed to produce elastic balls made of various polyhedrons using EVA (Ethylene Vinyl Acetate Copolymer), which is harmless to the human body, to significantly reduce costs and improve infants' creativity and understanding of shapes. It relates to a polyhedral elastic hole for development.

일반적으로 취학전 유아 및 초등학교 저학년의 어린이들은 호기심을 유발하 여 보다 효율적인 교육이 가능하도록 하면서 정서발달과 정서안정 등의 목적으로 다양한 교육용 완구를 사용하게 된다.In general, preschoolers and children in lower grades of the elementary school use a variety of educational toys for the purpose of emotional development and emotional stability while inducing curiosity to enable more efficient education.

특히 어린이들은 각종 다면체에 대한 교육을 필수적으로 필요로 하기 때문에 정사면체, 정육면체 등의 각종 다면체 블럭을 제작하여 다면체에 대한 형상과 특징 등을 교육시키는 동시에 놀이를 겸할 수 있도록 하는 것이었다.In particular, children need to be educated about various polyhedrons, so that various polyhedron blocks such as tetrahedrons and cubes can be produced to educate the shape and characteristics of the polyhedrons and to play a role.

종래에는 상기 다면체의 블럭을 대부분 나무를 이용하여 제작하거나 또는 내부에 스폰지를 충진시킨 후 원단으로 외면부를 감싸도록 박음질 고정하는 것이 주류를 이루는 것이었다.Conventionally, the block of the polyhedron is mostly made of wood or stuffed and fixed to wrap the outer surface with a fabric after filling a sponge therein.

그러나 전자의 나무를 이용하는 경우에는 외면부에 다양한 색상으로 도색을 함으로써 유아들의 특성상 다양한 원색으로 도색된 다면체의 블럭을 볼 경우 호기심에 의하여 입으로 먼저 가져가는 본능에 따라 환경호르몬 등에 위한 위생과 건강에 좋지 않은 영향을 미치는 것이었다.However, in the case of using the former wood, the outer surface is painted in various colors, and if you see blocks of polyhedrons painted in various primary colors due to the characteristics of the infants, you may be interested in hygiene and health for environmental hormones, etc. It was a bad influence.

또한, 딱딱하고 단단한 나무로 블럭을 구성함에 따라 유아들이 블럭을 가지고 놀 때 감촉이 부드럽지 못할 뿐만 아니라 이러한 블럭을 유아들이 던지는 등의 행동에 의해 주위에 있던 사람들이 다치는 등 각종 안전사고가 많이 발생되며, 제품의 제작에 코스트가 증가되어 경제성이 저하되는 문제점이 야기되는 것이었다.In addition, as the blocks are made of hard and hard wood, not only are the children feeling soft when they play with the blocks, but also many accidents such as those injured by people around them are caused by actions such as throwing these blocks. In addition, the cost is increased in the production of the product was to cause a problem that the economic efficiency is lowered.

한편 후자의 스폰지 및 원단을 이용하는 경우에는 제작에 따른 작업공정이 매우 번거롭고, 제작에 따른 시간 및 인력이 많이 소요되며, 스폰지 및 원단의 특성상 오염물질을 흡수함에 따라 위생상의 문제점은 그대로 노출되는 것이었다.On the other hand, in the case of using the latter sponge and fabric, the work process is very cumbersome, the time and manpower required for the production, and the hygienic problem was exposed as it absorbs contaminants due to the characteristics of the sponge and fabric.

본 고안은 상기한 종래의 다면체 블럭이 갖는 제반 문제점을 적극적으로 해소하기 위한 것으로, 인체에 무해한 EVA(Ethylene Vinyl Acetate Copolymer)를 원소재로 하여 사출 성형작업을 통해 각종 다면체를 갖는 탄성공을 대량으로 양산하도록 하여 코스트를 획기적으로 절감함은 물론 위생 및 청결을 보장하면서 유아의 창의력, 도형에 대한 이해력 등을 효율적으로 증진시킬 수 있도록 함을 고안의 주된 목적으로 하는 것이다.The present invention is to actively solve all the problems of the conventional polyhedral blocks described above, and in a large amount of elastic holes having various polyhedrons through injection molding operations using EVA (Ethylene Vinyl Acetate Copolymer), which is harmless to the human body, as a raw material. The main purpose of the devise is to enable mass production to dramatically reduce costs, ensure hygiene and cleanliness, and efficiently promote creativity and understanding of children.

본 고안의 목적을 효과적으로 달성하기 위한 바람직한 실시예의 구성에 대해 설명하기로 한다.The configuration of the preferred embodiment for effectively achieving the object of the present invention will be described.

본 고안은 나무 또는 스폰지 및 원단을 이용하여 내부가 꽉 채워진 형태로 다면체의 블럭을 구성하는 종래의 획일적인 구조를 탈피하여 EVA(Ethylene Vinyl Acetate Copolymer)를 원소재로 하여 내부가 비어 있는 중공(中空)의 탄성공(1)을 다면체로 구성함을 고안의 지배적인 특징으로 한다.The present invention avoids the conventional uniform structure constituting a block of polyhedron in the form of a tightly filled interior using wood or a sponge and a fabric, and uses an EVA (Ethylene Vinyl Acetate Copolymer) as a raw material. The dominant feature of the invention is that the elastic hole 1) is composed of a polyhedron.

상기한 특징적인 요지를 달성하기 위한 본 발명은 사출 성형작업을 통해 중공의 탄성공(1)을 대량으로 양산하되 각각의 외부면(2)이 합동인 정다각형의 영역으로 이루어지고 각각의 꼭지점에 대한 입체각(立體角)이 모두 상등인 볼록다면체의 형태로 구성된다. The present invention for achieving the above-mentioned characteristic gist is mass-produced hollow elastic holes (1) through the injection molding operation, but each of the outer surface (2) is composed of a regular polygonal region and for each vertex It is composed of convex polyhedrons whose solids are all equal.

즉 본 고안의 탄성공(1)은 다수의 외부면(2)이 모서리선(3)을 매개로 일체화 연결된 다면체로 구성되며, 상기 다면체의 탄성공(1)은 도 1 내지 도 5에 도시된 바와 같이 외부면(2)의 갯수가 4개, 6개, 8개, 12개, 20개로 실시될 수 있으며, 상 기 외부면의 갯수에 따라 정사면체, 정육면체, 정팔면체, 정십이면체, 정이십면체로 구성된다.That is, the elastic hole 1 of the present invention is composed of a polyhedron in which a plurality of outer surfaces 2 are integrally connected to each other via a corner line 3, and the elastic hole 1 of the polyhedron is shown in FIGS. 1 to 5. As described above, the number of outer surfaces 2 may be 4, 6, 8, 12, or 20, and according to the number of outer surfaces, tetrahedron, cube, octahedron, dodecahedron, and icosahedron. It is composed.

이러한 본 고안의 탄성공(1)은 에틸렌과 비닐아세테이트의 공중합체 수지인 The elastic hole (1) of the present invention is a copolymer resin of ethylene and vinyl acetate

Ethylene Vinyl Acetate Copolymer를 사용한 것으로, 이는 투명성, 유연성, 저온 취성 등이 우수하여 인체에 유해한 폴리염화비닐(PVC)의 대체 소재로 부각되고 있으며, 상기 EVA를 사용하면 유아들이 놀이중에 다면체의 탄성공(1)을 빨거나 입에 넣는 등의 행동을 하여도 인체에 해를 가하는 우려가 없으며, 사출 성형작업을 통해 대량으로 양산이 가능함으로써 제작에 따른 코스트를 획기적으로 절감하여 제품의 경쟁력을 제고할 수 있게 된다.Ethylene Vinyl Acetate Copolymer is used, which is excellent as transparency, flexibility, low temperature brittleness, and is emerging as an alternative material of polyvinyl chloride (PVC), which is harmful to the human body. 1) There is no risk of harming the human body even if sucking or putting it in the mouth, and mass production is possible through injection molding, which can drastically reduce the cost of manufacturing and enhance the competitiveness of the product. Will be.

또한, 본 고안의 다면체 탄성공(1)은 상기한 EVA는 물론 PE(polyethylene)를 원소재로 하여 제조하여도 무방하다.In addition, the polyhedral elastic hole (1) of the present invention may be manufactured using the above-described EVA as well as PE (polyethylene) as an raw material.

상기와 같이 다양한 각종 다면체로 구성되는 본 고안의 탄성공(1)은 다수개를 1세트로 하여 제공됨으로써 유아들이 도형을 이해하는 이해력을 증진시킴은 물론 놀이기구로 사용함으로써 지능계발의 원론적인 목적을 달성함에 어떠한 무리도 없게 된다. The elastic ball (1) of the present invention composed of a variety of polyhedrons as described above is provided by a plurality of sets as one set to increase the understanding of the children to understand the figure, as well as the use of play equipment as the principal purpose of the intelligent development There will be no strain to achieve this.

본 고안은 EVA를 원소재로 하여 사출 성형작업으로 각종 다면체의 탄성공을 대량으로 양산함으로써 제조에 따른 작업인력 및 시간을 획기적으로 단축함은 물론 생산에 따른 코스트를 절감하여 제품의 경쟁력을 제고할 수 있게 된다.The present invention is to reduce the labor cost and production time as well as the production cost by improving the production competitiveness by mass production of elastic balls of various polyhedrons by injection molding using EVA as a raw material. It becomes possible.

또한, 인체에 무해한 소재를 사용함으로써 유아들이 탄성공을 빨더라도 매우 위생적이며, 다면체의 탄성볼을 던지더라도 부상을 입게 될 우려가 없어 안전사고를 미연에 효과적으로 예방할 수 있는 효과를 제공한다.In addition, by using the material harmless to the human body is very hygienic even if the infant sucks the elastic ball, there is no fear of injury caused by throwing the elastic ball of the polyhedron provides an effect that can effectively prevent accidents in advance.
