BACKGROUND OF THE INVENTION 1. Field of the Invention [0001] The present invention relates to a pulling apparatus for blind,

The present invention relates to a blind traction device installed at an upper portion of a window for blocking a direct ray of light or an external visual line by downwardly or downwardly moving a plurality of slits when necessary. More specifically, When the lower line adjusting member is engaged in the latching section formed on the rotary member, the plurality of slits are downwardly rotated by the rotation of the lower line adjusting member and can be unfolded or folded, When the line adjusting member is caught by the latching portion formed on the rotary member, the slit is downwardly moved downward by a rotation of the upper line adjusting member from the plurality of slits located at the upper end among the plurality of slits, and is folded or unfolded. To a towing device.

Blinds are made of an insignificant shape by connecting metal, wood pieces or synthetic resin plates, and are installed in windows for the purpose of blocking direct sunlight or an external view.

In addition, blinds are divided into various types depending on the type, and are typically divided into Venetian Blind, Vertical Blind, Roll Screen Blind, and Pleated Blind.

That is, the Venetian blind is called Venetian blind since it is the most common blind started in Venezia, Italy. Compared to other types of blinds, it has excellent ventilation and slit widths are connected to adjust the degree of light and the angle of direct sunlight. It has the advantage of protecting the private life because it can block the eyes from the outside depending on the slit angle. Various materials such as aluminum, nonwoven fabric, fabric, and veneer are mainly used.

In addition, the vertical blind is not a vertical slit but a horizontal blind which can be installed in almost all windows such as a veranda window, an inclined window, or a horizontal window treated as a curved window as well as a general window There is an advantage.

In addition, the Roll Screen Blind is mainly used for controlling the intensity of direct sunlight rather than the angle of direct sunlight, and is installed with a single width and opened / closed by being rolled up or down. In addition, it has a merit that it can produce a softer atmosphere because it plays a role of filtering out direct sunlight once. The recently released 'Roll screen for system windows' is a product that installs blinds directly on the window frame, not on the ceiling. It has the advantage that it is not necessary to open or close the blinds separately when ventilating or opening the doors.

In addition, the Pleated Blind means, at first glance, a venetian blind in the sense of a 'wrinkle' blind, which is close to a deformed roll screen. It is suitable for soft and warm indoor production because it comes in direct sunlight once in the same way as roll screen. It is made of non-woven fabric and double gauze. It is characterized by smooth wrinkles and can be cleaned easily enough to drop dust There is an advantage.

The blind traction device according to the present invention can be applied to a venetian blind type blind, and a typical prior art related to the venetian blind is as follows.
