Abstract

A safety switch is provided to prevent any safety accidents due to wrong operations by operating the safety switch if two buttons are pushed. A safety switch includes a housing(10), a limit switch(11), a first operation button(14), and a second operation button(13). The housing forms an exterior of the safety switch. The limit switch is installed inside the housing rotatably around a hinge and includes a limit switch operation button formed on one side thereof. The first operation button is formed on one side of the housing, leads in and out the housing, and supports the limit switch for preventing the limit switch from rotating. The second operation button is formed on the other side of the housing and pushes the limit switch operation button after the first operation button is pushed for stopping rotation of the limit switch.

본 발명은 드릴과 예초기 등에 사용되는 안전 스위치에 관한 것으로, 작업자가 안전과 작업 준비가 안된 상태에서 스위치를 실수로 작동하여 안전사고가 발생하는 것을 방지할 수 있도록 한 안전스위치에 관한 것이다.The present invention relates to a safety switch used in a drill, a lawnmower, and the like, and relates to a safety switch that enables an operator to accidentally operate a switch in a state in which safety and work preparation are not performed, thereby preventing a safety accident.

일반적으로 드릴과 예초기 등은 칼날이나 드릴 날이 작업 면에 준비된 상태에서, 작동스위치를 사용하여 필요에 따라 작동할 수 있도록 하였다. 그러나 종래의 스위치들은 모두 스위치가 안전 토글 장치를 해제하여만 스위치가 눌리면서 작동하게 되어있다. 이 안전 토글 장치들은 다수개의 스프링으로 구성되어 있다. Generally, drills and lawn mowers can be operated as needed by using an operation switch with a blade or a drill blade prepared on the working surface. However, all the conventional switches are operated when the switch is pressed only when the switch releases the safety toggle device. These safety toggle devices consist of a number of springs.

이와 같은 기존의 안전 장치들은 다수개의 스프링으로 구성되어 있어 복잡한 기능을 수행하고 따라서 많은 부품으로 인해 고장 등의 원인이 되었다. 또한 토글 장치가 해제되지 않은 상태에서 무리한 힘을 줄 경우 토글 장치가 파손되어 안전스위치 기능을 수행하지 못하는 경우도 발생하고 있다. These existing safety devices are composed of a plurality of springs to perform a complex function, and therefore many components caused a failure. In addition, when the toggle device is not released, if the force is applied, the toggle device may be broken and fail to perform the safety switch function.

따라서, 본 발명은 상기한 종래의 문제점을 해결하기 위하여 안출한 것으로서, 두 개의 버튼을 동시에 눌러야만 작동할 수 있도록 하고, 사용자가 오조작하여도 해당되는 장치가 작동하는 것을 방지하여 안전사고가 발생하는 것을 방지하는데 그 목적이 있다.Therefore, the present invention has been made in order to solve the above-mentioned conventional problems, it is possible to operate only by pressing two buttons at the same time, the safety accident occurs by preventing the corresponding device from operating even if the user incorrectly operated The purpose is to prevent that.

상기 목적을 달성하기 위하여 본 발명은 상단부에 작동 버튼과 하단부의 작동 버튼이 동시에 눌러져야만 손잡이 안에 내장된 스위치의 작동 버튼이 눌러져서 작동하게 된다. 상단부 작동 버튼이 눌러지지 않은 상태에서 하단 작동 버튼을 작동할 경우 내장된 스위치는 회전 운동만 하고 스위치의 작동 버튼은 눌러지지 않아 작동되지 아니하는 것을 특징으로 한다.In order to achieve the above object, the present invention requires that an operation button and an operation button of the lower part be pressed at the same time, so that the operation button of the switch embedded in the handle is pressed and operated. When the lower operation button is operated while the upper operation button is not pressed, the built-in switch only rotates, and the operation button of the switch is not pressed and is not operated.

본 발명은 외관을 형성하는 하우징과, The present invention provides a housing forming an appearance,

상기 하우징 내부에 힌지를 중심으로 회동가능하도록 설치되고 일측에 리밋스위치작동버튼이 구비된 리밋스위치와,A limit switch installed inside the housing to be rotatable about a hinge and provided with a limit switch operation button at one side thereof;

상기 하우징의 일측에 입출이 가능하도록 구비되고, 상기 리밋스위치의 일측에 접하여 리밋스위치의 회동을 방지하도록 지지할 수 있는 제1작동버튼과,A first operation button provided at one side of the housing to enable entry and exit, the first operation button being in contact with one side of the limit switch to prevent rotation of the limit switch;

상기 하우징의 타측에 입출이 가능하도록 구비되고, 상기 제1작동버튼과 마주보는 방향에서 상기 리밋스위치작동버튼과 접하여 상기 제1작동버튼에 의해 상기 리밋스위치의 회동이 방지된 상태에서 눌러지면 상기 리밋스위치작동버튼을 가압하여 리밋스위치를 "온"시키는 제2작동버튼을 포함하여 구성된다.The limit is provided on the other side of the housing, the limit when in contact with the limit switch operation button in a direction facing the first operation button is pressed in a state that the rotation of the limit switch by the first operation button is prevented And a second operation button for pressing the switch operation button to turn on the limit switch.

이하,첨부된 도면을 참조하여 본 발명을 상세히 설명하면 다음과 같다.Hereinafter, the present invention will be described in detail with reference to the accompanying drawings.

도1에 도시된 바와 같이, 본 발명은 안전 스위치의 하우징(10)안에 리밋 스위치(11)가 위치하고, 상단부에 있는 작동 버튼(이하 제1작동버튼’이라 한다)(14)과 하단부에 있는 작동 버튼(이하 제2작동버튼’이라 한다)(13)이 있으며 리밋 스위치(11)가 힌지(12)에 의해 회전운동이 가능하도록 되어있는 몸체를 구성한다. 전원잭(15)은 리밋 스위치(11)의 연결단자에 연결된다. 이렇게 설치된 작동 버튼은 제1작동버튼(14)이 눌리거나 제2작동 버튼(13)이 눌릴 때 선택적으로 회전 운동을 하던지 또는 리밋 스위치 작동버튼(17)이 눌릴 수 있다. As shown in Fig. 1, in the present invention, the limit switch 11 is located in the housing 10 of the safety switch, and an operation button (hereinafter referred to as a first operation button ') 14 at the upper end and an operation at the lower end are shown. There is a button (hereinafter referred to as a second operation button) 13 and the limit switch 11 constitutes a body which allows the rotational movement by the hinge 12. The power jack 15 is connected to the connection terminal of the limit switch 11. The operation button installed as described above may be selectively rotated when the first operation button 14 is pressed or the second operation button 13 is pressed, or the limit switch operation button 17 may be pressed.

상기와같이구성된본발명의작동상태를살펴보면다음과같다.Looking at the operating state of the present invention configured as described above are as follows.

도2에 도시한 바와 같이, 사용자가 제1작동버튼(14)을 누르지 않은 상태에서 제2작동버튼(13)을 누른 경우를 나타내고 있으며 리밋 스위치(11)가 상단부가 구속되지 않은 상태에서 리밋 스위치(11)의 제2작동 버튼(13)이 눌리므로 힌지(12)를 중심으로 회전운동을 하게 되고 결국 스위치는 작동하지 않게 된다. As shown in FIG. 2, it shows a case where the user presses the second operation button 13 without pressing the first operation button 14, and the limit switch 11 is in a state where the upper end is not restrained. Since the second operation button 13 of (11) is pressed, the rotary movement is performed around the hinge 12, and the switch does not operate.

도3은 사용자가 제1작동 버튼(14)은 누르고 있는 상태에서 제2작동버튼(13)을 누른 경우를 나타내고 있으며 리밋 스위치(11)의 상단부가 구속되고3 shows a case in which the user presses the second operation button 13 while the first operation button 14 is pressed and the upper end of the limit switch 11 is restrained.

이와 동시에 제2작동버튼(13)을 누르므로 리밋 스위치(11)의 조작 버튼(17)이 눌리므로 스위치가 “온”의 상태로 된다. At the same time, since the operation button 17 of the limit switch 11 is pressed because the second operation button 13 is pressed, the switch is in the "on" state.

도4는 사용자의 편의를 위해 제1작동버튼(14)이 손쪽으로 옮겨짐으로써 조작이 용이하도록 한 다른 실시 예를 나타낸다. FIG. 4 shows another embodiment in which the first operation button 14 is moved toward the user's hand for ease of operation.

이상에서 살펴본 바와 같이, 본 발명은 이중으로 조작되는 안전스위치를 제공함으로써, 사용자가 오조작하여도 해당되는 장치가 작동하는 것을 방지하여 안전사고가 발생하는 것을 막을 수 있으며, 스프링등을 사용하지 않으므로 조립의 용이성과 고장을 줄일 수 있는 장점이 있는 것이다.As described above, the present invention by providing a safety switch that is operated in a double, it is possible to prevent the occurrence of a safety accident by preventing the operation of the corresponding device even if the user misoperation, it does not use a spring, etc. There is an advantage to ease of assembly and reduce the failure.
