본 고안은 착탈식 양날톱의 개량구조에 관한 것으로, 특히 자루부분을 연질 및 경질합성수지로 이중사출하여 쿠숀이 양호하면서 내구성이 뛰어나게 하고, 자루 양측면에는 수개의 구멍을 형성하여 장시간 사용하더라도 땀이 차지않도록 하며, 자루 선단에 삽입되어 양날톱을 연결고정시키는 톱날연결구 양측면에 형의 보강돌부를 형성함으로서 톱날연결구를 보다 튼튼하게 형성한 것이다.The present invention relates to an improved structure of a removable double-headed saw, and in particular, double injection of the bag part with soft and hard synthetic resin makes the cushion good and durable, and forms several holes on both sides of the bag so that sweat does not take up even if used for a long time. The saw blade connector is formed more firmly by forming reinforcement protrusions on both sides of the saw blade connector, which are inserted into the tip of the bag to connect and fix the saw blade.

주지된 바와 같이 착탈식 양날톱은 통상, 자루와 톱날연결구 및 톱날로 형성되어 있는데, 자루의 경우 목재 또는 합성수지재로 골조를 형성한 뒤 이곳에 고무카바를 삽입시킨 상태이기에, 사용도중 고무자체가 신축작용을 하게되어 자루와 카바가 따로도는 경우가 자주발생되고, 이에 따라 피절단물을 절단시 작업자의 의도대로 정확하게 절단하기 곤란한 폐단이 따랐던 것이다.As is well known, the removable double-saws are usually formed of a sack, saw blade connector and saw blade. In the case of a sack, the rubber body is stretched during use because the rubber cover is inserted therein after the frame is formed of wood or synthetic resin material. This often occurs when the bag and the cover is separated separately, according to the worker's intention when cutting the cutting object was difficult to follow the cutting edge.

또, 톱날연결구는 동일하게 형성된 두장의 철판을 일정한 간격(즉 톱날두께 만큼의 간격)을 유지시킨 상태에서 일체화시킨 것으로서, 철판두께가 그리 두껍게 형성될 수 없는 것이기에 (이는 톱의 중량을 감안하기 때문에 두꺼운 철판을 사용하기도 곤란함)톱날을 조립하여 사용중 톱날연결구 자체가 변형되거나 톱날자체가 흔들리는 경우도 잦을 수 밖에 없었고, 따라서 피가공물을 원활하게 절단할 수 없는 폐단이 따랐던 것이다.In addition, the saw blade connector is formed by integrating two identically formed iron plates in a state of maintaining a constant interval (that is, as much as the thickness of the saw blade), and the sheet thickness cannot be formed so thickly (because the weight of the saw is considered It is also difficult to use a thick steel plate), the saw blade connector itself is often deformed or the saw blade itself is shaken during the use of the saw blade assembly, so that the work was not possible to cut the workpiece smoothly.

따라서 본 고안은 전술한 종래의 제반문제점을 해결코져 안출된 것으로서, 특히, 착탈식 양날톱의 자루부분을 이중사출하되, 자루의 골조부분은 경질합성 수지로되게 하고, 골조와 표면카바는 연질의 합성수지로 되게하여 결국 자루골조와 카바가 일체로 사출성형되게 하며, 자루 양측면에 수개의 구멍을 형성하여 자루를 잡고 작업할 때 통풍이 원활하게 함으로서, 톱질할 때 항상 쾌적한 느낌을 갖도록 하려는데 그 목적이 있는 것이다.Therefore, the present invention has been devised to solve the above-mentioned conventional problems, and in particular, the double ejection of the bag portion of the removable double-head saw, the frame portion of the bag is made of a hard synthetic resin, the frame and the surface cover is made of soft synthetic resin The result is that the sack frame and the cover are integrally injection molded, and several holes are formed on both sides of the sack, so that the ventilation is smooth when the sack is held, so that the user always feels comfortable when sawing. .

또한, 자루에 끼워진 상태에서 양날톱을 결합시키도록된 톱날연결구는 두장의 철판 각각의 중앙부에 보강돌부를 형성함으로써, 무게는 종래와 같은면서도 보다 튼튼하고 내구성이 뛰어나도록 하여 톱의 수명을 연장시키는데 크게 일조할 수 있도록 하였다.In addition, the saw blade connector to join the saw blade in the state of being inserted into the bag by forming a reinforcing protrusion in the center of each of the two sheets of steel, so that the weight is more durable and durable than the conventional, greatly extending the life of the saw To help.

이하 본 고안의 구성을 첨부한 도면에 의거 상세히 설명한다.Hereinafter, the configuration of the present invention will be described in detail with reference to the accompanying drawings.

자루와 톱날연결구 및 톱날로 구성된 통상의 착탈식 양날톱에 있어서 자루(1)부분은 이중사출하되, 자루의 골조(2)부분은 경질합성수지로 형이 되게하고, 골조(2) 외표면 카바(3)부위는 골조(2)의 일체화되게하며 자루(1) 양측면에는 수개의 구멍(4)을 형성하여 손에 쥐었을 때 통풍이 가능하게 하고, 톱날연결구(5)는 두장의 철판(6)(6′)중앙부에 보강돌부(7)를 형성하여 연결구(5)의 내구성을 극대화시킨 것이다.In the conventional detachable double-sided blade consisting of a bag, a saw blade connector and a saw blade, the bag (1) part is double-injected, and the frame (2) part of the bag is shaped into a hard synthetic resin, and the frame (2) outer surface cover (3) The part is to be integrated of the frame (2) and the sides of the bag (1) to form a number of holes (4) to enable ventilation when grasped in the hand, the saw blade connector (5) is two sheets of iron plate (6) (6 ′) Is to maximize the durability of the connector (5) by forming a reinforcement protrusion (7) in the center.

미설명부호 11은 걸고리, 12는 걸고리작동핀, 13은 양날톱날, 14,14′걸림돌부, 15는 삽입요홈, 16은 걸림요홈, 17은 지지핀, 18은 가압요부, 19는 고정핀이다.Reference numeral 11 is a hook, 12 is a hook operating pin, 13 is a double-blade blade, 14, 14 'locking projections, 15 is the insertion groove, 16 is the locking groove, 17 is the support pin, 18 is the pressing recess, 19 is a fixed pin .

이와 같이 구성된 본 고안은, 자루부분이 이중사출로 되어 카바(3)와 골조(2)가 일체로 형성된 것이기에 사용중 카바(3)와 골조(2)가 따로 회전되는 경우가 예방되어 매우 안정적으로 사용할 수 있게되는 것이다.The present invention configured as described above, because the bag part is double injection, the cover (3) and the frame (2) is formed integrally, so that the cover (3) and the frame (2) are rotated separately during use, which is very stable to use. It will be possible.

즉, 자루(1)의 구성에 있어서 골조(2)부분이 경질합성수지로 형성되고, 골조(2) 외주면에는 카바(3)부분이 헛도는 등의 폐단이 자연히 일소되어 피절단물을 작업자의 의도대로 안정적으로 절단시킬수 있게 된다는 것이다.That is, in the structure of the bag 1, the frame 2 portion is formed of a hard synthetic resin, and the closed edge of the cover 3 is completely disappeared on the outer circumference of the frame 2 so that the cutting object is removed. It can be cut stably as intended.

또한 본고안은 자루(1) 양측면에수개의 구멍(4)을 형성하였음으로 자루(1)를 쥐고 작업할 때 손에 땀이 차는 점을 예방할수 있으며, 이에 따라 오랜시간 작업하더라도 쾌적한 기분으로 작업이 가능하여 작업능률 및 효율을 극대화 시킬수 있게되는 것이다.In addition, this paper has several holes (4) formed on both sides of the bag (1) to prevent the sweat on the hand when holding the bag (1), thereby working in a pleasant mood even if working for a long time This is possible to maximize the work efficiency and efficiency.

그리고 톱날연결구(5)는 두장의 철판(6)(6′)중앙부에 보강돌부(7)를 형성하였음으로, 톱날(13)을 결합사용시 견고하게 지지하여 주게되고 휨 발생이 적어 내구성 및 신뢰성을 극대화 시켜줄수 있게되는 것이다.And saw blade connector (5) formed the reinforcing protrusions (7) in the center of the two sheets of steel plate (6) (6 '), to support the saw blade (13) when combined use firmly and less bending occurs less durability and reliability It will be able to maximize.

상술한 바와같이 본 고안은 자루(1)를 이중사출 하였기에골조(2)와 카바(3)가 견고하게 조립구성되는데다가 자루(1) 자체에구멍(4)을 형성하여 작업중 손에 땀이 차는 경우를 예방할 수 있고, 더불어 톱날연결구(5)에 보강돌부(7)를 형성하였기에 종래와 같은 중량이면서도 내구성이 극대화되는 매우 유용한 고안인 것이다.As described above, the present invention is a double-injection of the bag (1), so that the frame (2) and the cover (3) is firmly assembled and formed a hole (4) in the bag (1) itself to sweat the hands during work If the case can be prevented, and the reinforcing protrusions (7) formed in the saw blade connector (5) is a very useful design that maximizes the weight and durability as in the prior art.
