목재용 나사못{Screw for wood}Screw for wood

본 발명은 목재용 나사못에 관한 것으로서, 특히 목재용 나사못(이하 나사못이라 칭함)을 목재에 박으면 헤드부가 목재 표면의 필름부를 파고들어갈 때 필름지의 홀 테두리가 울지 않고, 깨끗하게 홀이 형성되면서 박히도록 하여 외관미를 향상시킬 수 있도록 함은 물론 헤드부 저면에 형성된 칼날이 쉽게 마모되지 않도록 하여 나사못을 반복 재사용할 수 있음에 따라 나사못 구입 비용을 절감할 수 있는 목재용 나사못에 관한 것이다.
[0001] The present invention relates to a screw for wood, and particularly, when a screw for wood (hereinafter referred to as a screw) is put on wood, the hole of the film is not opened when the head part penetrates the film part of the wood surface, To improve the appearance of the head, as well as to prevent the blade formed on the bottom of the head portion from being easily worn so that the screw can be reused repeatedly, thereby reducing the cost of purchasing a screw.

일반적으로 나사못은 헤드의 형상 모양에 따라 둥근머리 나사, 접시머리 나사, 둥근접시머리 나사 등으로 구분되며, 용도에 따라 나무에 박는 목재용 나사못과 석고보드용 나사못. 벽돌이나 콘크리트용 나사못이 있고, 그 외에도 철판이나 빔 등에 박을 수 있는 드릴 나사못이 있다.In general, screws are divided into round head screws, plate head screws and round plate head screws according to the shape of the head. There are screws for brick and concrete, and there are also drill screws that can be used for iron plates or beams.

상기의 나사못들은 대부분 "＋"자 또는 "ㅡ"자 등의 공구 홈이 표면에 구비되어 드라이버 등의 공구로 회전되는 헤드가 몸체의 일측에 구비되며, 몸체의 외주면에는 나사산이 코일 형태로 권회되어 형성되고, 몸체의 하부에는 접합 대상물을 파고들어 갈 수 있도록 끝이 뾰족한 첨단으로 된 선단부가 구비된다.Most of the above screws are provided with a tool groove such as a "+" or "-" tool on its surface and a head rotated by a tool such as a screwdriver is provided on one side of the body. And a tip portion having a sharp tip with a sharp end is provided at a lower portion of the body so that the object can be pierced.

그런데, 상기 선단부의 첨단이 단순하게 뾰족한 구조의 나사못은 목재 접합물에 사용할 경우 홀을 형성하면서 파고들어가는데 시간이 많이 걸리고 힘이 많이 들어 전동공구를 사용하더라도 하루에 계속하여 수많은 나사못을 박아야 할 경우 작업 능률이 떨어져서 작업자들이 쉽게 지치고 힘들어 한다.However, when the tip of the tip is simply pointed, it is time-consuming to enter the hole while forming a hole in the case of using a wood joint, and even if a power tool is used, Work efficiency is low and workers are easily tired and tired.

이를 해결하기 위해 나사못이 접합물을 파고들어갈 때 절삭 커팅하면서 파고들어 갈 수 있도록 선단부의 일측 또는 양측에 절삭날(커팅날)이 구비되는 드릴 나사못 형태로 만들기도 한다.In order to solve this problem, a drill screw having a cutting edge (cutting blade) is provided on one side or both sides of the tip so that the screw can dig while cutting cutting when the joint is pierced.

또한, 헤드부 저면에 칼날을 형성하여 나사못의 죄임시 헤드부의 진입에 의한 변형 우려가 없도록 하여 외관미를 향상시키는 것이다.In addition, a blade is formed on the bottom of the head portion to prevent the deformation of the screw due to entry of the temporary head portion of the screw, thereby improving the appearance.

이러한 선행 기술로는 아래의 특허문헌에 개시된 대한민국 등록실용신안 제20-0381873호(2005.04.06.등록)의 판넬 부착용 나사못(이하 '선행기술'이라 칭함)가 있다.Such prior arts include a panel mounting screw (hereinafter referred to as "prior art") of Korean Registered Utility Model No. 20-0381873 (registered April 26, 2005) disclosed in the following patent documents.

상기 선행기술은 접시머리의 급경사진 삽입부 외측에 완만하게 경사진 가압부가 빙둘러서 형성되고, 상기 삽입부로 부터 가압부를 잇는 긴 칼날 사이사이에 가압부로 부터 돌출 형성되는 짧은 칼날을 갖도록 구성되어 목재의 필름지 표면을 쉽게 파고 들어가도록 한 것이다.
The prior art is configured such that a gently inclined pressurizing portion is formed on the outside of the steep slanting insertion portion of the dish head and is provided with a short blade protruding from the pressing portion between the long blades connecting the pressing portion with the insertion portion, The film surface is easily digged.
