Description
본 고안은 칠판에 관한 것으로서, 특히 빛반사가 되지 않는 무광(無光) 칠판에 관한 것이다.The present invention relates to a blackboard, and in particular to a non-reflective matte blackboard.
선행기술의 칠판에 있어서 수성펜으로 쓰는 칠판이 알려져 있으며, 이러한 칠판은 백묵가루가 발생하지 않기 때문에 건강이 이로운 장점이 있다.In the blackboard of the prior art, a blackboard written with a water-based pen is known, and this blackboard has a merit of good health since chalk powder does not occur.
그러나 선행기술의 칠판에 있어서는 빛이 반사되는 매끄러운 표면의 유광칠판이기 때문에 칠판을 바라보는 사람으로 하여금 잘 안보이게 하고 눈을 피곤하게하며 집중력을 가질 수 없게 하는 문제를 초래하게 한다.However, in the blackboard of the prior art, since it is a glossy surface with a smooth surface on which light is reflected, it causes a problem that makes the viewer who is looking at the blackboard invisible, tired of eyes, and unable to concentrate.
그리고 수성펜만 지워지므로 필기가 가능하고 유성펜은 지워지지 않기 때문에 사용 할 수 없는 필기구의 사용 제한이 따르므로 불편이 있다.And since only the aqueous pen is erased, writing is possible, and since the oil pen is not erased, it is inconvenient to use a writing instrument that cannot be used.
본 고안은 상기한 바와 같은 종래의 제반 문제점을 감안하여, 빛반사가 되지않으면서도 유성 및 수성펜으로도 필기를 할 수 있는 무광칠판을 제공하려는데 그목적이 있는 것이다.The present invention is to provide a matte blackboard that can be written even with oil-based and water-based pen without light reflection in view of the conventional problems as described above.
상기한 목적을 달성하기 위한 본 고안은, 바닥판부재를 갖는 칠판에 있어서;상기 바닥판부재의 표면에 부착되고 필기면에 빚을 난반사시키기 위한 조밀한 요철면을 갖는 실리콘칠판부재를 포함하여 구성됨을 그 특징으로 한다.The present invention for achieving the above object, in the blackboard having a bottom plate member; is attached to the surface of the bottom plate member and comprises a silicon blackboard member having a dense uneven surface for diffuse reflection on the writing surface It is characterized by.

본 고안을 첨부된 바람직한 실시도면에 의거하여 보다 상세히 설명하면 다음과 같다.When the present invention is described in more detail based on the accompanying preferred embodiments as follows.
도 1은 본 고안에 따른 실리콘칠판부재의 제조과정을 보인 것으로서, 호퍼(1)에는 용융된 반액체 상태의 액상실리콘(2)이 담겨지고, 이 액상실리콘(2)은 두께 조절이 가능하도록 조작되는 두께조절겸용 제조로울러(3)에 의해서 판형태의 반 응고된 실리콘칠판부재(20)로 제조된다.Figure 1 shows the manufacturing process of the silicon board member according to the present invention, the hopper (1) is contained in the molten semi-liquid liquid silicon (2), the liquid silicon (2) is manipulated to enable thickness control It is made of a semi-solidified silicon board member 20 in the form of a plate by the thickness control combined use roller (3).
상기 실리콘칠판부재(20)는 표면이 오톨도톨하게 부식 처리된 부식판부재(4)로 이송되어 가압로울러(5)에 의해서 가압되게 된다.The silicon blackboard member 20 is transferred to the corrosion plate member 4 whose surface is corroded so that it is pressed by the pressure roller 5.
그에따라, 부식판부재(4)에 접촉된 실리콘칠판부재(20)의 일측표면에는 오톨도톨하고도 조밀한 요철면(21)이 형성되는 상태가 된다. 부식판부재(4)에 밀착된 상태의 실리콘칠판부재(20)는 약 500℃의 건조기(6)를 통과함으로써 완전히 응고된실리콘칠판부재(20)를 얻게 된다.Accordingly, one side surface of the silicon blackboard member 20 in contact with the corrosion plate member 4 is in a state in which a dense uneven surface 21 is formed, even though it is tortol. The silicon blackboard member 20 in close contact with the corrosion plate member 4 passes through the dryer 6 at about 500 ° C., thereby obtaining a completely solidified silicon blackboard member 20.
이와같이 형성된 실리콘칠판부재(20)는 요구되는 크기로 절단되어 칠판(10)을 구성하는 바닥판부재(11)의 표면에 부착되며, 이때 요철면(21)이 필기면이 되도록 부착되는 것이다.(도2 참조)Thus formed silicon board member 20 is cut to the required size is attached to the surface of the bottom plate member 11 constituting the blackboard 10, wherein the uneven surface 21 is attached so that the writing surface. See Figure 2)
상기 요철면(21)은 육안으로는 식별이 불가능한 조밀한 상태의 요철면(21)을갖도록 형성된다.The uneven surface 21 is formed to have a uneven surface 21 in a dense state that cannot be identified with the naked eye.
그러나 도 3에 보인바와 같이 오톨도톨한 요철면(21)을 실리콘칠판부재(20)가 갖게 되는 것이며, 그로인해 화살표 도시와 같이 정면으로 입사되는 빛은 측면방향으로 난반사되는 상태가 되기 때문에 실리콘칠판부재(20)를 정면으로 바라보게되는 경우 무광상태가 되어 눈이 부시지 않게 된다.However, as shown in FIG. 3, the silicon board member 20 has the uneven surface 21 which is tortholized, and thus the light incident to the front as shown by the arrow is diffusely reflected in the lateral direction. When looking at the member 20 to the front is a matte state will not dare eyes.
그리고 실리콘칠판부재(20)는 실리콘의 물질특성상 수성 뿐만 아니라 유성잉크도 잘 지워지기 때문에 수성펜을 포함하여 유성펜으로도 필기를 할 수 있다.In addition, since the silicone blackboard member 20 is not only water-based, but also oil-based ink, due to the material properties of silicon, the silicon board member 20 can also be written with an oil-based pen including an aqueous pen.
이상의 설명에 따르면, 본 고안에 의해 빛이 정면으로 반사되지 않는 무광칠판을 제공하므로 칠판 표면에 필기된 것을 잘 볼 수 있으며 눈의 피곤함이 없고 집중력 있게 칠판을 볼 수 있는 효과를 제공한다.According to the above description, since the present invention provides a matte blackboard that does not reflect light in front, it is possible to see what is written on the surface of the blackboard well, and provides the effect of focusing on the blackboard without eye fatigue.
그리고 수성펜을 포함하여 유성펜도 사용 가능하게 되므로 필기도구의 폭넓은 선택을 도모하고 편리한 사용을 도모하게 하는 효과를 가지도록 하는 유용한 고안이다.In addition, since the oil pen, including an aqueous pen, can be used, it is a useful design to have a wide selection of writing instruments and to have an effect of facilitating convenient use.
