Description

슬라이딩 안전커터Sliding safety cutter
본 발명은 슬라이딩 안전커터에 관한 것으로, 더욱 상세하게는 자를 사용하지 않으면서도 절단대상물을 직선으로 자를 수 있는 슬라이딩 안전커터에 관한 것이다.The present invention relates to a sliding safety cutter, and more particularly to a sliding safety cutter that can cut the cutting object in a straight line without using a ruler.
일반적으로 칼로 종이와 같은 절단대상물을 직선으로 자르기 위해서는 자를절단대상물 위에 얹혀놓고 자의 측면을 따라 칼날을 이동시켜 절단대상물을 자르게 된다.In general, to cut a cutting object such as paper with a knife in a straight line, the ruler is placed on the cutting object and the blade is moved along the side of the ruler to cut the cutting object.
이와 같은 방법은 사용자가 절단대상물을 자르는 동안 자의 측면을 따라 이동하는 칼날의 각도를 일정하게 유지하기가 어렵게 된다.This method makes it difficult for the user to maintain a constant angle of the blade moving along the side of the ruler while cutting the cutting object.
이 경우, 플라스틱이 대부분인 자의 측면을 상하게 함과 동시에 사용자의 부주의로 칼날이 자의 측면을 타고 자의 상부면으로 이동하여 사용자의 손이 칼날에 의해 손상되는 일이 자주 발생한다.In this case, the plastic is mostly damaged the side of the ruler and at the same time the user's carelessly moves the blade by the side of the ruler to the upper surface of the ruler and the user's hand is often damaged.
특히 사용자가 어린이의 경우 사용 미숙으로 손을 다칠 우려가 더욱 높아진다.In particular, the user is more likely to hurt the hand due to inexperienced use of children.
이와 같은 문제점을 개선하기 위해 하기 특허문헌 1(이하, '종래기술 1')의 "이동식 절단용 칼을 부착한 자"가 개발되었다.In order to improve such a problem, the "patent with a removable cutting knife" of Patent Document 1 (hereinafter, "Prior Art 1") has been developed.
도 1에 도시한 바와 같이, 종래기술 1의 이동식 절단용 칼을 부착한 자는, 자(2)와, 누룸판(6) 및 칼날(7)로 구성된다.As shown in Fig. 1, the ruler with the movable cutting knife of the prior art 1 is composed of a ruler 2, a nurum plate 6 and a blade 7.
상기 자(2)에는 레일 역할을 하는 두 개의 홈(1)이 형성되며, 상기 누룸판(6)에는 홈(1)에 끼워지는 요철부분(3)이 형성된다.The ruler (2) is formed with two grooves (1) serving as rails, and the uneven portion (3) to be fitted to the groove (1) is formed in the nurum plate (6).
상기 누룸판(6)에는 탄성지지대(4) 및 칼집부분(5)이 형성된다.An elastic support 4 and a sheath portion 5 are formed in the nurum plate 6.
이에 따라, 상기 누룸판(6)은 자(2)의 홈(1)을 따라 이동하며 절단대상물을 직선으로 자르게 된다.Accordingly, the nurum plate 6 moves along the groove 1 of the ruler 2 to cut the cutting object in a straight line.
그러나, 종래기술 1의 이동식 절단용 칼을 부착한 자의 경우에는 자에 레일 역할을 하는 홈을 형성해야 할 뿐만 아니라 칼날을 포함하는 누룸판도 별도 구비되어 있어 제조비용이 높은 문제점이 있었다.However, in the case of the ruler attached to the mobile cutting knife of the prior art 1, not only the grooves serving as the rails need to be formed on the ruler, but also a Nurum plate including the blade is provided, which causes a high manufacturing cost.
뿐만 아니라, 칼날이 외부 노출된 상태를 유지하여 안전사고가 발생하게 된다.In addition, the blade is exposed to the outside to cause a safety accident.
이와 같은 문제점을 개선하기 위해 본 발명의 출원인은 하기 특허문헌 2(이하, '종래기술 2')의 "탄성 칼날돌출식 안전커터"를 개발하였다.In order to improve such a problem, the applicant of the present invention has developed the "elastic blade protrusion safety cutter" of the following Patent Document 2 (hereinafter, 'prior art 2').
도 2에 도시한 바와 같이, 종래기술 2의 탄성 칼날 돌출식 안전커터(100)는, 본체(110a)를 절단대상물(3) 상에 위치시킨 상태에서 하부방향으로 가압하는 경우에만 칼날이 돌출되도록 구성된다.As shown in Figure 2, the elastic blade protruding safety cutter 100 of the prior art 2, so that the blade protrudes only when the main body 110a is pressed in the downward direction in the state placed on the cutting object (3). It is composed.
구체적으로, 본체(110a)에 형성된 슬릿(111)과 탄성지지부(113)에 의해 가압시에만 칼날이 돌출되어 안전사고의 위험없이 누구나 안전하게 사용할 수 있게 된다.Specifically, the blade protrudes only when pressed by the slit 111 and the elastic support 113 formed in the main body 110a, so that anyone can safely use it without a risk of safety accident.
그러나, 종래기술 2의 안전커터는 절단대상물을 직선으로 자르기 위해선 자가 필요했다.However, the safety cutter of the prior art 2 needed a ruler to cut the cutting object in a straight line.
따라서, 자를 사용하지 않으면서도 절단대상물을 직선을 자를 수 있음과 동시에 안전사고를 방지하는 개선된 형태의 안전커터의 개발이 요구되고 있는 실정이다.Therefore, there is a demand for the development of an improved safety cutter that can cut a cutting object without using a ruler and at the same time prevent safety accidents.
