본고안은 칠판하부의 분필선반체대에 끼워 고정된 분진상자를 설치하며 분필가루를 수거하게된 위생칠판에 관한 것이다.This paper relates to a sanitary blackboard where chalk dust is collected by installing a dust box fixed to a chalk shelf under the board.
종래에 칠판을 사용할때 글씨를 쓰고 지우는 과정에서 분필 가루가 날려 사용자의 건강을 크게 해치는 원인이 되었고, 이것을 방지키위해 휠타내장전기지우개나 지우개털이등이 고안되었으나 조작의 번거로움은 물론 고가로 인해 일반적으로 널리 쓰이지 못하였던 것이다.In the past, when writing and erasing a blackboard, chalk powder was blown in the process of writing and erasing, which caused great harm to the user's health.In order to prevent this, a wheel loader, an electronic eraser, an eraser hair, etc. were devised. It was not widely used in general.
본 고안은 이러한 단점을 일시에 해소키위한 목적으로 안출된 것으로써 구성과 작용효과를 첨부도면에 의해 상세히 설명하면 다음과 같다.The present invention has been devised for the purpose of eliminating these shortcomings at once, and the configuration and effect will be described in detail by the accompanying drawings.
칠판(1)의 분필선반(2)위에 유도홈(3)이 다수 형성된 체대(4)를 볼트고정구(5)에 볼트조임하여 고정한뒤, 망(6)으로 상부를 덮은 분진상자(7) (7')의 바닥면 양측에 형성된 고정돌기 (8)를 체대(4)의 유도홈(3)에 끼워 고정시킨 구성으로 미설명 부호9는 칠판 지우개이다.The dust box 7 which covers the upper part with a mesh 6 is fixed by bolt-fastening to the bolt fixture 5 the body 4 having a plurality of guide grooves 3 formed on the chalk shelf 2 of the blackboard 1. The fixed projection 8 formed on both sides of the bottom surface of 7 ') is fixed to the guide groove 3 of the body 4 and the reference numeral 9 is a blackboard eraser.
이렇게 구성된 본고안의 작용효과를 설명하면, 칠판(1)의 길이에 맞춰 조립된 체대(4)의 바닥면에 약간의 물이 담긴 분진상자(7) (7')를 끼워 조립한 후, 사용자가 글씨를 쓰고 지울때 날리는 분필 가루가 칠판(1)면을 타고 하부로 떨어질때 분진상자(7)상부의 망(6)을 통과하여 바닥면의 물에 흡수되어 바람에 날리지 않게 되고, 글씨를 지운뒤 칠판지우개(9)를 망(6)위에 올려놓으면서 약간만 문지르면 칠판지우개(9)면에 붙어있던 분필가루가 떨어져 자주 털어주지않고 사용할 수 있으며, 칠판(1)사용후에 분진상자(7)를 당기면 체대(4)의 유도홈(3)에 삽입되어있던 고정돌기(8)가 분리되어 부분적으로 분진상자의 청소를 할 수 있어 항상 철결한 상태를 유지시킬 수 있게된 것으로 칠판(1)의 크기에 비례하는 다수의 분진상자(7)를 설치하기에 용이하고 또한 기존칠판의 하단에 연결된 분필선반위에도 쉽게 조립하게 되어 강의실에 오염되는 분필가루의 공해를 막을 수 있어 강사와 학생들의 건강을 지킬 수 있게되는 매우 유익한 고안인 것이다.Explaining the operation effect of the present proposal, the dust box (7) (7 ') containing some water is assembled to the bottom surface of the body (4) assembled to the length of the blackboard (1), and then the user When writing and erasing letters, the chalk powder flying down the board (1) surface falls down through the dust box (7), the upper mesh (6) and is absorbed by the water on the bottom so that it is not blown by the wind. If you rub a little while putting the backboard eraser (9) on the net (6), you can use it without dropping the chalk powder attached to the backboard eraser (9), and if you pull the dust box (7) after using the board (1) The fixing protrusions 8 inserted into the guide grooves 3 of the body 4 are separated to partially clean the dust box so that they can always be kept in a tight state. Easy to install multiple proportional dust boxes 7 Chalk connected even on the shelf at the bottom of the plate can easily be assembled to stop the pollution of chalk in a classroom that is pollution will be very beneficial devise being able to keep the teachers and students of health.
