Abstract

The present invention relates to an operating apparatus of a blind having a function for safety. According to the present invention, when operating a blind, a separation is not made even when high tension is created on a single line, whereas a clutch and the line are separated from a main body even when only small tension is created on the entire line when the blind is in a stationary state, so that children can be surely prevented from having an accident due to the line.

[Patent Document 1] Korean Patent Registration No. 1020130099652 Blind equipped with safety device

종래 블라인드의 안전장치는 크게 줄이 분리되는 분리형과 줄을 벽에 부착하는 부착형의 두가지로 구분할 수 가 있다. 기존의 분리형 안전장치는 줄이 분리가 되는 기준을 특정하기 매우 어렵다. 온도나 습도, 햇볕에 노출되는 시간에 따라 수많은 변수가 작용하기 때문이다. 너무 쉽게 분리가 되면 브라인드를 작동 도중에 분리가 되고 너무 큰 하중에 분리가 되면 어린이의 안전을 지킬 수 없는 이중적인 문제를 가지고 있다. 또한 고정형 안전장치는 장소에 따라 벽에 고정할 수 없는 곳도 있고 소비자가 원하지 않는 경우가 많은 문제점이 있다. 가장 이상적인 분리형 안전장치는 블라인드를 작동시킬시에는 아무리 큰 힘이 걸려도 줄이 분리가 되지 않고 작동을 하지 않을시에는 아주 작은 힘에도 분리가 되는것이다.The safety device of the conventional blind can be divided into two types, a detachable type in which the strings are separated from each other and an attachment type in which the strings are attached to the wall. Conventional detachable safety devices are very difficult to specify the criteria by which the rope is separated. This is due to a number of variables depending on temperature, humidity, and exposure time to the sun. If the separation is too easy, the blind is separated during operation and has a double problem that can not keep the child safe if it is separated by too large a load. In addition, there are some places where the fixed safety device can not be fixed to the wall depending on the place, and there are many cases where the consumer does not want it. The most ideal detachable safeguard is that when the blind is operated, the line is not separated even if it takes a great deal of force, but it is separated even if it is a very small force when it is not operated.

본 발명은 위에서 언급한 이상적인 안전 기능을 구비한 블라인드의 구동장치를 얻는데 그 목적이 있다.An object of the present invention is to provide a driving apparatus for a blind having the above-mentioned ideal safety function.

기존의 블라인드 구동장치는 줄에 의해 작동되는 클러치와 일체형으로 구성되어 있다. 하지만 본 발명은 일정 이상의 장력이 두 줄에 작용하면 구동창치로 부터 줄과 클러치가 분리가 된다. 구동축(4)이 결합되는 프레임의 내측에 클러치의 회전축(13)이 결합될 수 있도록 아랫부분이 트인 탄력성이 있는 가이드(8)를 형성하고 구동축(4)의 일측에 클러치의 원통형의 결합돌기(11)가 결합되도록 반원형의 결합홈을 가진 2개의 결합돌기(12)를 형성하고 클러치의 회전축(13)에 구동축의 결합돌기(12)와 결합할 수 있는 원통형의 2개의 결합돌기(11)를 형성한 클러치를 도면과 같이 조립하여서 된 구조이고 구동축에 형성된 결합돌기의 반원형의 결합홈과 클러치에 형성된 원통형의 결합돌기의 형상이 중요한 기능이다.The conventional blind driving apparatus is constituted integrally with a clutch operated by a string. However, according to the present invention, when a tension greater than a certain level acts on two lines, the line and the clutch are separated from each other. A flexible guide 8 is formed at the bottom of the frame so that the rotary shaft 13 of the clutch can be engaged with the inner side of the frame to which the drive shaft 4 is coupled. Two coupling protrusions 12 having a semicircular coupling groove are formed so as to couple the coupling protrusions 12 of the drive shaft to the rotary shaft 13 of the clutch, The shape of the clutch formed by assembling the clutch as shown in the figure, and the shape of the semi-circular coupling groove of the coupling protrusion formed on the drive shaft and the shape of the cylindrical coupling protrusion formed on the clutch are important functions.

본 발명의 구동장치는 블라인드를 구동시키기 위해 한쪽 줄에 큰 하중이 걸려도 정상적인 작동이 가능하고 정지 상태에서는 줄 전체에 작은 하중이 걸려도 줄이 분리가 되므로 블라인드의 완벽한 작동과 어린이의 안전을 확실히 보장할 수 있는 효과가 있다.     The driving apparatus of the present invention can operate normally even when a large load is applied to one side of the blind to drive the blind, and the line is separated even when a small load is applied to the entire side of the line in the stopped state. There is an effect that can be.

첨부된 도면에 의거 본 발명의 구조와 작용을 상술하면 다음과 같다. 도면에서 보는 바와 같이 본 발명은 블라인드를 구동시키는 구동장치로서 프레임(1),클러치(3),구동축(4),역회전 방지부(5),동력 전달부(6),스프링(7)으로 구성된다(도1). 프레임의 내측에 클러치의 회전축(13)이 결합되어 회전할 수 있고 아랫부분이 트여 벌어지면서 클러치가 분리 결합될 수 있도록 탄성을 가진 가이드(8)를 형성한다. 구동축의 일측에는 클러치의 결합돌기(11)가 결합될 수 있도록 반원형의 홈을 가진 2개의 결합돌기(12)를 형성하고 클러치의 회전축(13)에는 구동축에 형성한 결합돌기(12)와 결합될 수 있도록 원통형의 2개의 결합돌기(11)를 형성한다(도2). 이와 같은 구조를 가진 본 발명의 구동장치는 한 방향으로 줄을 당기면 약한 힘으로도 클러치만 회전하게 되며 구동축과 클러치에 형성된 결합돌기가 결합하게 되면 줄에 큰 하중이 작용하더라도 줄에 작용하는 힘에 따라 구동축과 클러치의 결합돌기의 회전방향으로의 결합력도 증가하게 되어 클러치가 분리되지 않지만(도3) 클러치가 회전하지 않을때는 결합력이 떨어져 줄 전체에 일정 이상의 하중이 작용하면 가이드(8)의 입구(14)가 벌어지면서 클러치가 본체로 부터 분리가 되는 것이다(도 1). 이때 가이드(8)는 클러치가 회전하여 결합돌기(11,12)가 결합될 때 까지만 클러치를 잡아주는 역할을 하게 되고 결합된 후에는 결합돌기의 결합력으로 인해 분리가 되지 않는 것이다. 분리된 클러치는 줄과 함께 가이드의 입구(14)를 통해 쉽게 재결합할 수가 있다.The structure and operation of the present invention will now be described in detail with reference to the accompanying drawings. As shown in the drawings, the present invention is a drive device for driving a blind, comprising a frame 1, a clutch 3, a drive shaft 4, a reverse rotation preventing portion 5, a power transmitting portion 6, (Fig. 1). A guide 8 having elasticity is formed so that the rotary shaft 13 of the clutch can be coupled to the inner side of the frame to be rotatable and the lower portion can be opened to allow the clutch to be separated and engaged. Two coupling protrusions 12 having a semicircular groove are formed on one side of the driving shaft so that the coupling protrusions 11 of the clutch can be engaged with the coupling protrusions 12 formed on the driving shaft. Two coupling projections 11 of cylindrical shape are formed (Fig. 2). In the driving apparatus of the present invention having such a structure, when the line is pulled in one direction, only the clutch rotates with a weak force. When the driving shaft and the coupling protrusion formed on the clutch are engaged, even if a large load is applied to the line, 3). When the clutch does not rotate, the coupling force is reduced. When a load greater than a certain level is applied to the whole of the clutch, the coupling protrusion of the coupling protrusion of the driving shaft and the clutch in the rotation direction of the coupling protrusion of the clutch The clutch 14 is disengaged and the clutch is separated from the main body (Fig. 1). At this time, the guide 8 serves to hold the clutch only until the clutch rotates and the engaging projections 11 and 12 are engaged, and after the engaging, the engaging protrusions 11 and 12 are not separated due to the coupling force of the engaging projections. The disengaged clutch can easily rejoin through the inlet 14 of the guide with the rope.
