Abstract

본 고안은 나사머리 홈을 삼각형()으로 형성한 삼각형()구멍붙이 나사 및 이 나사홈에 적합한 드라이브에 관한 것이다. 지금까지 나사머리홈은 일자(-)홈과 십자(+)홈을 사용하고 있다. 그 중에서도 십자(+)구멍붙이 나사를 주로 사용하고 있다. 본 고안의 삼각형()구멍붙이 나사는 일자(-) 및 십자(+)구멍붙이 나사의 중간 형태로 일자(-)구멍붙이 나사가 나사홈이 2갈래 이고, 십자(+)구멍붙이 나사가 나사홈이 4갈래 인데 반하여 삼각형()구멍붙이 나사는 나사홈이 3갈래로 되어있다. 본 고안의 삼각형()구멍붙이 나사는 십자(+)구멍붙이 나사의 여러 장점을 다 가지고 있으며, 동시에 십자(+)구멍붙이 나사와 비교하여 나사홈이 차지하는 체적이 적으므로 홈파기가 더 용이하다. 특히 나사머리가 적은 나사를 제작시 본 고안의 삼각형()구멍붙이 나사가 훨씬 유리하다.The present invention is a screw head groove triangular ( ) Formed by a triangle ( ) Screws with holes and drives suitable for this screw groove. To date, screw head grooves use straight (-) and cross (+) grooves. Among them, screws with cross (+) holes are mainly used. Triangle of the present invention The slotted screw is the middle type of the straight (-) and cross (+) slotted screws. In contrast to the triangle ( A hole screw has three slots. Triangle of the present invention Slotted screws have all the advantages of cross-headed screws, and at the same time, they are easier to dig because of the smaller volume of screw grooves compared to cross-headed screws. Especially when making a screw with less screw head, Hole screw is much more advantageous.

Description

삼각형구멍붙이 나사{a screw with screwhead on triangle hole}{A screw with screwhead on triangle hole}

본 고안은 나사의 나사머리홈에 관한 것으로 종래에는 나사머리홈이 일자(-)형과 십자(+)형을 사용하였다. 그 중에서도 십자(+)구멍붙이 나사를 주로 사용하였다. 그러나 십자(+)구멍붙이 나사도 사용하다 보면 나사홈이 망가짐으로 인한 애로가 가끔씩 발생하며, 특히 나사머리가 작은 나사를 제작시 나사홈이 차지하는 표면적이 넓어 제작을 어렵게하고, 또 홈을 작게 만듬으로 인하여 나사작업에도 불편이 많았다.The present invention relates to a screw head groove of the screw, and conventionally, the screw head groove used a straight (-) type and cross (+) type. Among them, screws with cross (+) holes are mainly used. However, when cross-headed screws are also used, difficulties due to broken screw grooves sometimes occur. Especially, when making a screw with a small head, the surface area occupied by the screw groove makes the production difficult and makes the groove small. Due to the screw work was inconvenient.

본 고안은 일자(-)형과 십자(+)형 나사의 중간 형태인 삼각()형으로 나사머리홈을 냄으로 인하여 십자(+)구멍붙이 나사의 장점을 유지하면서도 위와 같은 십자(+)구멍붙이 나사의 단점을 보완하고자 하였다.The present invention is a triangular shape, which is the middle form of the straight (-) and cross (+) screws. By making the screw head groove in the shape of (), we tried to compensate for the shortcomings of the Phillips-head screws while maintaining the advantages of the Phillips-head screws.

도 1은 본 고안의 삼각형()구멍붙이 나사의 일 예를 나타낸 예시도1 is a triangle of the present invention ( A diagram showing an example of a screw with a hole

도 2는 십자(+)구멍붙이 나사의 일 예를 나타낸 예시도2 is an exemplary view showing an example of a screw with a cross hole (+)

본 고안은 일자(-)구멍붙이 나사와 도2의 십자(+)구멍붙이 나사의 중간에 해당하는 것으로 도1에서 보는 바와같이 나사 머리홈을 120도 간격으로 세갈래로 낸 것이다.The present invention corresponds to the middle of the flat head screw and the cross-head screw of Figure 2, as shown in Figure 1 is a three-headed screw head groove 120 degrees apart.

도2의 십자(+)구멍붙이 나사가 나사머리홈이 90도 각도로 네갈래로 형성된 데 비하여 도1의 본 고안의 삼각형()구멍붙이 나사머리홈은 세갈래로 형성됨으로 십자(+)구멍붙이 나사에 비하여 홈의 체적을 줄이는 효과가 있으므로 제작이 더 용이하고 특히 나사머리가 작은 나사의 경우 십자(+)구멍붙이 나사에 비하여 나사머리홈의 크기를 더 크게 할 수도 있으므로 나사작업을 더 용이하게 하는 효과를 거둘 수 있다.Compared to the cross head screw of FIG. 2, the screw head groove is formed in four angles at an angle of 90 degrees. The three-pronged screw head grooves reduce the volume of the grooves compared to the cross-headed screws, making them easier to manufacture. Especially for screws with small screw heads, the cross-headed screws Compared with this, the size of the screw head groove can be made larger, thereby making the screwing easier.
