Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a vertical blind, and particularly to a vertical blind having a structure suitable for do-it-yourself (DIY) blinds.

Traditionally, vertical blinds were designed and installed by specialized contractors according to the dimensions of the mounting area, and were not something that could be done by amateurs.

The main reason for this is that the mechanism of conventional vertical blinds is complicated and its adjustment is troublesome.

Especially in the most common type of vertical blinds,
A screw rod for advancing the louver and a rotating rod for rotating each louver are arranged in parallel in the helad rail, and it is not only difficult to assemble but also difficult to adjust, and the angle of the louver may be distorted. If this occurs, correct opening/closing operations may not be possible, and there is a possibility that the operating mechanism may be damaged due to forced operation.

In addition, it is not easy to adjust the dimensions of the headrail, and conventionally,
Depending on the dimensions of the mounting part, it was necessary to manufacture a product that matched the dimensions at the factory.

The present invention aims to improve the drawbacks of the conventional vertical blinds and provide a vertical blind with a simple structure that can be assembled extremely easily even by an amateur.

In addition, the present invention also requires the horizontal dimension of the vertical blind, that is, the length of the head rail and the louver rotating rod supported within the head rail, the vertical dimension of the vertical blind, that is, the height of the louver, and the dimension of the mounting location. The purpose of the present invention is to provide a vertical blind that can be adjusted extremely easily, even by an amateur, according to the situation.

In addition, in conventional vertical blinds, the louver is generally made of fabric, and a bag-shaped part is formed at the bottom end of the louver, and a balance weight is usually inserted and fixed into it. Since the bag-like portion is formed, it is not possible to adjust the dimensions of the louver in the field, and therefore it has not been possible to create a louver whose vertical dimension can be adjusted very easily.

The present invention provides a louver that allows the vertical dimensions of such vertical blinds to be easily adjusted.The present invention allows the dimensions of the louver to be adjusted extremely easily on site, and has an extremely simple structure and a louver. The balance weight can be easily and firmly fixed to the louver without requiring any preliminary processing such as creating a bag-like part on the weight itself, and
This product provides a louver for vertical blinds that can be easily and firmly fixed to the louver with a hook using the same method, eliminating the need to slit the louver in advance at the factory. Since it is only necessary to slit the width, it is possible to provide louvers with a wider variety of colors, patterns, patterns, etc. than in the past.

The vertical blind according to the present invention has a headrail made of extruded aluminum material that has a uniform cross section over its entire length and can be cut to any length, and a headrail that is fitted and fixed to both ends of the headrail that has been cut to any length. The end cap is cut to an appropriate length according to the length of the herad rail, and is passed through the end caps at both ends of the herad rail.
A louver rotating rod is pivotally supported by this, a plurality of carriers are fitted to the head rail so as to slide vertically along the head rail, and a hook is supported by a hook projecting downward from each carrier. a mass carrier disposed at the head of the row of these carriers and slidable along the head rail; and a spacer connecting the carriers to each other so as to maintain the carriers at a constant distance from each other. The head rail is provided with through holes at regular intervals in the longitudinal direction as a guide for cutting the head rail to the desired length, and the louver is made of louver material cut to the desired length. It is characterized in that the upper and lower ends are clamped and fixed to the upper and lower support frames.

Additionally, the vertical blind according to the present invention is provided with a rod support that supports the above-mentioned rotating rond in the middle when the blind is opened, that is, when the carrier is shifted toward one end within the head rail, and the rod support is A stop is provided in the headrail which is magnetically attracted to the front surface of the mass carrier and which stops the rod support at an intermediate position of the headrail when the blind is opened.
