본 고안은 톱날을 적당하게 교환할 수 있도록 한 톱날 교환식 톱에 관한 것이다.The present invention relates to a saw blade interchangeable saw that allows the saw blade to be properly replaced.
종래의 톱날 교환용 톱은 장착부분의 구조가 복잡하거나, 톱날이 확실하게 고정되지 않아서 사용하기 곤란한 결점이 있었다.Conventional saw blade replacement saws have a drawback in that the structure of the mounting portion is complicated, or the saw blade is not fixed securely and is difficult to use.
이와 같은 실정에 비추어, 본 고안은 간단한 구조로서 톱날을 손잡이 자루에 대하여 흔들리지 않고 견고하게 조정할 수 있도록 한 것이다.In light of the above situation, the present invention is a simple structure that allows the saw blade to be firmly adjusted without being shaken with respect to the handle bag.
본 고안의 실시예를 첨부한 도면에 따라서 설명한다.An embodiment of the present invention will be described with reference to the accompanying drawings.
본 고안의 톱은 톱날(1)의 배부(1a)를 단면이 역 U자 모양의 감착구(2)에 끼우고, 다시 톱날과 감착구를 손잡이 자루(3)에 장착하는 것이다.The saw of the present invention inserts the back portion 1a of the saw blade 1 into an inverted U-shaped fitting port 2 in cross section, and attaches the saw blade and the fitting port to the handle bag 3 again.
톱날(1)의 근기부인 감입부(4)의 하단연에는 요결부(5)를, 감착구(2)의 하단연에는 톱날(1)의 요결부(5)에 일치하는 위치에 이것과 동일한 폭으로서 요결부(5)의 깊이(a)보다도 그 깊이(b)가 깊은 요결부(6)를 각각 설치하고, 감착구(2)를 감착하였을 때 감입부(4)의 요결부(5)의 상연이 감착구(2)의 요결부(6)의 상연보다도 아랫쪽으로 돌출하도록 한다.The lower end edge of the indentation part 4 which is the root part of the saw blade 1, the concave part 5, and the lower end edge of the fitting opening 2, are the same in this position to the concave part 5 of the saw blade 1 The concave part 5 of the fitting part 4 when the concave part 6 which is deeper than the depth a of the concave part 5 as a width | variety, respectively, is attached, and the fitting port 2 is squeezed. The upper edge of the protrusion protrudes below the upper edge of the concave portion 6 of the fitting 2.
감착구(2)를 감착하여 일체적으로 한 톱날(1)의 갑입부(4) 부분을 손잡이 자루(3)의 감입공(7)내에 삽입하고, 손잡이 자루(3)에는 외부에서 전기한 톱날(1)의 요결부(5)에 일치하는 하부 위치에 그 요결부(5)의 폭과 대략 동일한 지름의 고정볼트(8)를 끼워서 그 고정볼트(8)의 선단부분을 요결부(5)(6)내에 면하게 하고, 선단으로서 감입부(4)의 요결부(5)의 상연을 압압하여 톱날(1)을 감착구(2)에 밀착시키고, 손잡이 자루(3)에 대하여 톱날(1)과 감착부(2)를 고정한다.A portion of the inlet portion 4 of the saw blade 1 integrally attached to the fitting fitting 2 is inserted into the fitting hole 7 of the handle bag 3, and the saw blade which is externally inserted into the handle bag 3 In the lower position corresponding to the concave part 5 of (1), a fixing bolt 8 having a diameter approximately equal to the width of the concave part 5 is inserted, and the tip of the fixing bolt 8 is inserted into the concave part 5. (6) and the top edge of the concave part 5 of the fitting part 4 is pressed as the tip, and the saw blade 1 is brought into close contact with the fitting port 2, and the saw blade 1 with respect to the handle bag 3 And the fitting part (2).
손잡이 자루(3)는 합성수지를 사용하여 중공으로 성형한 것으로서, 이 경우 세로 방향으로 둘로 분할한 대칭형으로 성형하고, 내부에 적당한 보강재를 입설 형성한 것을 용착 또는 접착하여 일체로 한다.The handle bag 3 is formed by using a synthetic resin in a hollow shape. In this case, the handle bag 3 is molded in a symmetrical shape divided in two in the longitudinal direction, and is integrally formed by welding or adhering a suitable reinforcing material into the interior.
손잡이 자루(3)의 소정 위치에 감입공(7)을 형성함에는 둘로 분할한 성형품의 각각 그것에 감입공의 상하 양단연에 해당하는 부분에 평행한 보강재(9a)(9b)를, 또 그 안쪽 단부에 보강재(9c)를 입설하고, 두 부분을 일체로 하였을 때에 보강재 끼리 서로가 밀착하여 감입공(7)이 형성되도록 한다.In forming the indentation hole 7 at the predetermined position of the handle bag 3, the reinforcement material 9a (9b) parallel to the part corresponding to the upper and lower edges of the indentation hole of each of the molded parts divided into two, and the inside thereof A reinforcing material 9c is placed at the end, and when the two parts are integrated, the reinforcing materials are brought into close contact with each other so that the inlet hole 7 is formed.
또, 감입공(7)의 측면에 상당하는 부분에는 보강재(9a)보다 높이가 낮은 보강재(10)를 보강재(9a)와 평행하게 입설하여 측벽을 대신하도록하며, 또한 감입부(4) 부분을 삽입할 때의 안내부가 되도록 한다.In the portion corresponding to the side surface of the indentation hole 7, a reinforcing member 10 having a height lower than that of the reinforcing member 9a is placed in parallel with the reinforcing member 9a so as to replace the side wall. It should be a guide part when inserting it.
이와 같이 구성되는 감입공(7)의 하부에는 나사 구멍(11)을 설치하고, 그 중간부에 너트(12)가 끼워지는 감합공(13)을 성형하여 놓는다.The screw hole 11 is provided in the lower part of the fitting hole 7 comprised in this way, and the fitting hole 13 which the nut 12 fits in the intermediate part is shape | molded.
조립에 있어서는 먼저 감합공(13)에 너트(12)를 끼우고, 둘로 분할된 것을 접합하는 것만으로서 손잡이 자루(3)를 간단하게 완성할 수가 있으며, 경량이며 또한 견고한 것으로 완성시킬 수가 있다.In assembling, the handle bag 3 can be simply completed by simply inserting the nut 12 into the fitting hole 13 and then joining the two divided pieces, and can be completed with a lightweight and sturdy one.
톱날(1)의 배부(1a)를 감착구(2)에 끼워서 요결부(5)와 (6)을 합치시키고, 감입부(4)를 감입공(7) 내에 삽입하고, 나사구멍(11)에서 고정볼트(8)를 끼워서 볼트(8)의 선단부분을 감입부(4)와 감착구(2)의 요결부(5)(6)내에 끼워 넣는다.Inserting the back portion 1a of the saw blade 1 into the fitting port 2 to join the concave portions 5 and 6, inserting the fitting portion 4 into the fitting hole 7, the screw hole 11 The end of the bolt (8) into the concave part (5) and the concave part (5) of the fitting hole (2) by inserting the fixing bolt (8).
이때 요결부(5)의 상연은 요결부(6)의 상연보다 아랫쪽에 있기 때문에, 고정볼트(3)의 선단은 감입부(4)의 요결부(5)의 상연에만 닿게되어 이것을 밀어 올리기 때문에 톱날(1)의 배부(1a)와 감입부(4)가 감착구(2)에 강하게 압압되고, 밀착되어 그 부분이 견고하게 고정된다.At this time, since the upper edge of the concave portion 5 is lower than the upper edge of the concave portion 6, the tip of the fixing bolt 3 touches only the upper edge of the concave portion 5 of the indented portion 4 and pushes it up. The back portion 1a and the fitting portion 4 of the saw blade 1 are strongly pressed against the fitting port 2, and are closely attached to each other so that the portion thereof is firmly fixed.
또, 고정볼트(8)의 지름은 요결부의 폭에 대략 동일하기 때문에 요결부(5)와 (6)내에 볼트의 선단부분이 끼워져 있는 한 그 부분이 계합하여 톱날(1) 및 감착구(2)는 절대로 움직이거나 손잡이 자루(3)에서 빠져 나오는 일 없이 확실하게 유지된다.In addition, since the diameter of the fixing bolt 8 is approximately equal to the width of the concave portion, as long as the distal end portion of the bolt is fitted in the concave portion 5 and 6, the portion engages and the saw blade 1 and the fitting hole ( 2) is securely held without ever moving or exiting the handle bag (3).
만약, 감착구(2)의 요결부(6)의 깊이(b)를 요결부(5)의 깊이(a)보다도 얕게 하였을 경우는 고정볼트(8)의 선단은 감착구(2)만을 압압하게 되어 톱날(1)을 직접 고정할 수가 없으며, 가령 예컨대 감착구와 톱날과의 감합을 견고하게 하드라도 일체로 하지 않는한 흔들거리게 되어서 사용에 불편한 것으로 된다.If the depth b of the concave portion 6 of the fitting port 2 is made shallower than the depth a of the concave portion 5, the tip of the fixing bolt 8 is pressed against the fitting port 2 only. As a result, the saw blade 1 cannot be fixed directly. For example, the saw blade 1 is shaken as long as the fitting between the fitting and the saw blade is firmly hard even if it is hard, but it is inconvenient to use.
톱날을 교환할 때에는 고정볼트(8)를 늦추고 감착구(2)와 아울러 톱날(1)을 감입공(7)에서 빼어내어 다른 톱날을 감착구에 갈아 끼워서 사용할 수가 있다.When replacing the saw blade, the fixing bolt (8) can be slowed down and the fitting hole (2) and the saw blade (1) can be removed from the fitting hole (7), and the other saw blade can be replaced by the fitting hole.
본 고안에 의하면 극히 얇은 톱날(1)을 감착구(2)로서 보강하여 톱날의 굴곡을 억지하고, 고정볼트(8)의 선단이 톱날(1)의 감입부(4)에 설치한 요결부(5)의 상연을 직접 압압하여 톱날(1)을 감착구(2)에 밀착시켜서 고정하기 때문에 톱날에 힘이 가해져도 흔들거리는 일 없이 견고하게 고정되어 사용하기 편리한 톱을 제공할 수 있다.According to the present invention, an extremely thin saw blade (1) is reinforced as a fitting hole (2) to suppress the bending of the saw blade, and the concave portion of the fixing bolt (8) is provided on the fitting portion (4) of the saw blade ( Since the top edge of 5) is directly pressed to fix the saw blade 1 in close contact with the fitting port 2, it is possible to provide a saw that is firmly fixed and easy to use even when a force is applied to the saw blade without shaking.
