Lifting device for blinds {device for driving blind}

The present invention relates to a device for lifting, lowering and angle adjustment of a horizontal blind, and more particularly to a blind consisting of a lifting drum for raising and lowering the slats of the blind and an angle adjusting drum for adjusting the angle of the slats.

Currently used blinds are divided into horizontal type and vertical type (vertical), and the disadvantage of vertical is that most products are made of fabric, so it is difficult to completely block the light from the outside and is easy to burn. There is a problem of getting dirty.

Therefore, horizontal blinds made of hard slats are used a lot. Especially, recently, wood-coated products can completely control the amount of light while completely blocking sunlight, and can be easily wiped without discoloration. Will be used.

In addition, such horizontal blinds are divided into manual blinds which are operated by a user to directly control the lifting, lowering and angle adjustment, and electric blinds which are operated by an electric method. Strap for the angle adjustment is provided on the outside, in the case of the electric blind is to operate using a separate controller.

The upper part of the blind is provided with means for raising and lowering the slats and adjusting the angle, so that the means for raising, lowering and adjusting the angle are integrated into one unit for ease of manufacturing and driving the blind. In order to change the angle of the slat, the upper end of the ladder line connected to the slat is fixed to the wire spring of the angle adjustment drum, but the problem with this is that the wire spring and the angle adjustment with the wire spring wound on the outer circumferential surface of the angle adjustment drum. Slip phenomenon occurs between the drums, so if the user touches the slats or blows strong winds from the outside, the angle of the slats is randomly changed. Therefore, it is difficult to adjust the amount of light in the blinds, and the user again measures the angles. Having inconvenience to be adjusted The.

In addition, if the user manually manipulates or operates the controller for the raising, lowering and angle adjustment of the blind after the angle is arbitrarily changed, there is a possibility that a malfunction occurs in the operation since the angle of the slat has already been changed from its original position. Repeatedly this will eventually cause abnormalities and defects in the product.

The present invention has been made to solve the above-mentioned problems, the structure of the elevating drum and the angle adjustment drum is made of a simple structure, so that the angle does not change arbitrarily without the user's operation or the operation of the controller malfunction The purpose is to provide a blind that can be operated accurately without.

In order to achieve the above object, the present invention provides a blind in which the lifting drum and the angle adjusting drum are integrally assembled to have a rotatable structure, and the angle adjusting drum is rotated only within a predetermined angle by the stopper so that the ladder rope is wound. A separate operating tool is inserted into the lifting drum and the operating tool is inserted into the lifting drum to control the rotation of the angle adjustment drum by using an anti-rotation spring to prevent the slat of the blind from being rotated arbitrarily. It is.

As described above, the present invention enables to adjust both the lifting and lowering height of the slats and the inclination angle of the slats by using the lifting device formed integrally, while preventing the slip phenomenon of the ladder rope adjusting the angle of the slats, the angle of the blinds. Is not changed arbitrarily, and the operation for adjusting the slat's up, down and angle is smoothly and stably without flow, minimizing the defect or defect rate of the blind even in the long-term use and improving the merchandise of the blind.
