Description

Folding saw

본 고안은 접는톱의 개량고안에 관한 것으로, 더욱 구체적으로는 톱자루의 수납실에서 톱날을 펼쳐서 톱을 사용하는 동안 톱날을 고정하고 있는 푸시버튼이 눌려져서 톱날이 임의적으로 접히는 것을 잠금레버에 의해 방지함과 아울러 톱날고정수단의 견고성을 크게 향상시켜 톱을 보다 안전하게 사용할수 있도록 한 것이다.The present invention relates to an improved design of a folding saw, and more specifically, to prevent the saw blade from being arbitrarily folded by a lock lever by pushing a push button that secures the saw blade while the saw is used by unfolding the saw blade in the storage compartment of the saw case. In addition, the saw blade fixing means to significantly improve the robustness to use the saw more safely.

종래의 접는톱에는 푸시버튼의 걸림턱이 톱날의 고정홈에 끼워져서 펼쳐진 톱날을 고정시키도록 만들어 사용하였으나 작업과정에서 톱자루 상측부에 설치된 푸시버튼을 잘못누르게 되면 펼져진 톱날의 고정상태가 풀려서 톱날이 흔들리게 되거나 접혀져서 예기치 못한 안전사고가 발생하는 등의 문제점이 있었다.The conventional folding saw was used to make the saw jaw of the push button is inserted into the fixing groove of the saw blade to secure the unfolded saw blade, but if the push button installed in the upper part of the saw stool is wrongly pressed, the fixed state of the unfolded saw blade is released by saw blade There was a problem such as an unexpected safety accident caused by the shaking or folding.

그래서 본 출원인에 의해 푸시버튼을 잠금상태로 만드는 잠금버튼이 구비된 접는톱(실용신안등록제151557호)이 고안되어 톱을 사용하는 동안에 톱날이 임의적으로 접히는 것을 방지할수 있게 되었는바 본 고안은 이를 개량고안하여서 된 것이다.Thus, the present inventors have devised a folding saw (Utility Model Registration No. 151557) equipped with a locking button to lock the pushbutton by the present applicant to prevent the saw blade from being folded arbitrarily while using the saw. It was designed.

본 고안은 톱자루의 수납실에 금속제의 지지대를 설치하고 지지대 상측에 금속제의 푸시버튼을 탄성지지되게 축설하여 지지대 선단의 고정축공에 톱날을 고정나사봉으로 고정하여 푸시버튼의 걸림턱이 톱날고정홈에 끼워지게 하고 푸시버튼의 후단단턱에 반구형의 접촉 받침봉으로 된 잠금레버를 회전하여 푸시버튼의 작금작용이 이루어지도록 한 것이다.The present invention installs a metal support in the storage compartment of the saw case and installs a metal push button on the upper side of the support so that the elastic support is supported. It is to be fitted to the push button of the push button is made by rotating the locking lever of the hemispherical contact support rod on the rear end of the push button.

톱자루(10)에 수납실(11)이 구성되고 톱자루(10)선단에 톱날(50)을 회전가능하게 결합하여 톱날(50)을 절첩할수 있게 하되 톱날(50)회전부에 형성된 고정홈(51)은 푸시버튼(30)의 걸림턱(31)에 접촉되어 톱날을 고정하는 것에 있어서, 상기 수납실(11)에 금속제의 지지대(20)를 설치하되 지지대(20)상측에 스프링(32)으로 탄성지지되고 걸림턱(31)을 가진 금속제의 푸시버튼(30)을 축설하고 지지대(20)의 지지축공(21)과 고정축공(22)에 지지축핀(23)과 톱날(50)이 끼워지는 고정나사봉(24)을 끼워 톱자루(10)에 고정하며 푸시버튼(30)후단의 단턱(33)하부에 반구형으로 편심된 접촉받침봉(41)을 축설한 잠금레버(40)의 회전에 의해 푸시버튼(30)의 잠금작용이 이루어지도록 한다.The storage compartment 11 is formed in the sawcase 10, and the saw blade 50 is rotatably coupled to the top of the sawcase 10 so as to be able to fold the saw blade 50, but the fixing groove 51 formed in the saw blade 50 rotates. Is fixed to the saw blade in contact with the locking jaw 31 of the push button 30, the metal support 20 is installed in the storage chamber 11, but the spring (32) above the support 20 is elastic The support shaft pin 23 and the saw blade 50 are fitted into the support shaft hole 21 and the fixed shaft hole 22 of the support stand 20 and the metal push button 30 is supported and the locking jaw 31 is fixed. Pushed by the rotation of the lock lever 40 in which the screw rod 24 is fixed to the saw case 10 and the contact support rod 41 eccentrically eccentrically formed under the step 33 of the rear end of the pushbutton 30. The locking operation of the button 30 is made.

잠금레버(40)는 선단 내측에 걸림돌기(42)를 형성하여 톱자루(10)에 양측으로 형성시킨 걸림홈(12)에 선택적으로 끼워지도록 하되 잠금레버(40)결합부는 톱자루(10)일측에서 결합나사(43)로 고정되어 스프링(44)에 의해 결합나사(43)방향으로당김작용이 이루어지도록 하여 정지핀(13)에 의해 제한된 잠금레버(40)회전상태에서의 걸림돌기(42)를 걸림홈(12)에 탄력적으로 끼워지게 한다The locking lever 40 has a locking protrusion 42 formed inside the tip to be selectively fitted into the locking groove 12 formed on both sides of the saw bag 10, but the locking lever 40 is coupled to the saw blade 10 at one side. It is fixed by the coupling screw 43 so that the pulling action is made in the direction of the coupling screw 43 by the spring 44 so that the locking projections 42 in the locked state of the locking lever 40 limited by the stop pin 13. Resiliently fit into the locking groove 12

이와같이된 본 고안은 톱을 사용하고자 할때 톱자루(10)의 수납실(11)에서 톱날(50)을 꺼내어 펼치면 톱날(50)의 회전부에 형성된 고정홈(51)에 스프링(32)의 탄력을 받는 푸시버튼(30)의 선단걸림턱(31)이 끼워져 톱날(50)을 펼친 상태로 고정하게 되고 이와반대로 푸시버튼(30)의 후단을 누르게되면 선단의 걸림턱(31)이 고정홈(51)에서 이격되어 톱날(50)이 접히게 된다.When the saw is intended to use the saw when the saw blade (50) in the storage chamber 11 of the saw 10 to extend the spring (32) in the fixing groove 51 formed in the rotating portion of the saw blade 50 Receiving the front end of the push button 30 of the push button 30 is fixed to the saw blade 50 in the unfolded state and on the contrary, when pressing the rear end of the push button 30, the locking step 31 of the front end is fixed groove (51) The saw blade 50 is folded away from).

이렇게 톱날(50)이 펼쳐져 푸시버튼(30)으로 고정된 상태에서 잠금레버(40)를 회전하여 도4에서와 같이 접촉받침봉(41)의 상향접촉면이 푸시버튼(30)의 후방단턱(33)에 받쳐지게 되면 푸시버튼(30)의 눌름작용이 이루어지지 않고 고정상태로 되므로 톱을 사용하는 과정에서 푸시버튼(30)이 임의적으로 눌러져서 톱날이 접히는 것을 방지하게 되며, 잠금레버(40)를 회전하여 도5에서와 같이 접촉받침봉(41)의 하향접촉면을 푸시버튼(30)의 후방단턱(33)에 위치시키면 푸시버튼(30)을 누를수 있게 된다.As the saw blade 50 is unfolded and fixed by the push button 30, the locking lever 40 is rotated so that the upward contact surface of the contact supporting rod 41 is the rear step 33 of the push button 30 as shown in FIG. When the support button is pressed, the pressing action of the push button 30 is not made, so that the push button 30 is randomly pressed in the process of using the saw to prevent the saw blade from being folded, and the lock lever 40 Rotate to position the downward contact surface of the contact support rod 41 on the rear step 33 of the push button 30 as shown in Figure 5 it is possible to press the push button (30).

이렇게 톱날 펼친상태를 2중으로 고정하는 접는 톱의 톱날고정부재가 금속제의 지지대(20)와 푸시버튼(30)으로 구성되어 있어서 톱날이 펼쳐진 상태에서의 견고한 톱날고정수단을 갖게 된다.The saw blade fixing member of the folding saw for fixing the saw blade unfolded in this way is composed of a metal support 20 and the push button 30 to have a solid saw blade fixing means in the saw blade unfolded state.

이와같이 본 고안의 접는 톱은 반구형으로 편심된 접촉받침봉이 축설되어 있는 잠금레버의 회전작용에 의해 푸시버튼의 잠금작용이 이루어져서 펼친상태의 톱날이 임의적으로 접히는 것을 방지하면서 금속제의 지지대와 푸시버튼에 의해 톱날고정수단의 견고성을 크게 향상시켜 톱을 보다 안전하게 사용할수 있는 이점이 있다.Thus, the folding saw of the present invention is made by a metal support and a push button while preventing the folding of the saw blade in an unfolded state by the locking action of the push button by the rotation of the locking lever in which the contact support rod eccentrically eccentrically is arranged. There is an advantage that the saw can be used more safely by improving the firmness of the saw blade fixing means.
