Description

[Detailed Description of the Invention] Purpose of the Invention (Field of Industrial Application) This invention relates to a horizontal blind in which a head box is divided in its longitudinal direction.

(Prior Art) Horizontal blinds installed inside windows, etc. have a number of slats of the same length supported vertically from a head box by ladder cords. Therefore, if a ventilation fan or the like is installed in a part of the window, blinds are installed to avoid that part.

(Problem to be solved by the invention) With the conventional blinds mentioned above, if they are installed avoiding a ventilation fan installed in a window, the lower part of the ventilation fan will be in a state where there is no blind, so it cannot be seen from outside the window. lighting cannot be reliably adjusted.

Structure of the invention (Means for solving the problems) In order to solve the above problems, this invention has two head boxes 2a, 2b, which are divided into at least two parts in the longitudinal direction and fixed apart from each other in the vertical direction.
A large number of slats 5, 6 are supported by a ladder cord 4 between the top box 2c and one bottom box 7 located below the head boxes 2a, 2b, 2c.

(Function) If a ventilation fan or the like is placed above the head box 2b located below by the above method, a blind is installed below and to the side of the ventilation fan while avoiding the ventilation fan.

(Embodiment) An embodiment embodying this invention will be described below with reference to the drawings. The headbox of the blind 1 is divided into three parts, and is divided into first, second, and third headboxes 2a, 2b, and 2c. The first and third head boxes 2a, 2c on both sides are fixed to a window frame (not shown), and the second head box 2b in the center is attached to the lower frame 3a of a square support frame 3 fixed to the window frame. The head boxes 2a and 2c are fixed to the head boxes 2a and 2c, and are located below the first and third head boxes 2a and 2c.

Two ladder cords 4 are suspended from each head box 2a, 2b, 2c and are suspended from a hanging shaft (not shown) rotatably supported within each head box 2a, 2b, 2c. Below the second head box 2b, a large number of long slats 5 corresponding to the sum of the lengths of the head boxes 2a, 2b, and 2c are supported across each ladder cord 4, and above the second head box 2b, Short slats 6 corresponding to the lengths of the first and third headboxes 2a, 2c are supported below both headboxes 2a, 2c, respectively.

The lower end of each ladder cord 4 is wound around an angle adjustment shaft (not shown) within a bottom box 7 fixed to a window frame, and the angle adjustment shaft is rotatably supported within the bottom box 7. An angle adjustment string 8 hanging from the center of the bottom box 7 has its base end wrapped around an angle adjustment shaft inside the bottom box 7. By operating the angle adjustment string 8, the angle adjustment shaft is rotated, and as the angle adjustment shaft rotates, the angles of the slats 5 and 6 are adjusted in the same phase via the ladder cord 4.

Now, the blind 1 as described above is divided into three head boxes 2a, 2b, and 2c, and the second head box 2b in the center is fixed to the lower frame 3a of the support frame 3. That is, there is a space in which no slats exist between the short slats 6 supported by the first and third head boxes 2a, 2c. Therefore, when a ventilation fan f or a beam of a building is placed within this support frame 3 as shown in FIG. By operating all the slats 5 and 6 at the same time using a common angle adjustment string 8, the lighting from outside the window can be easily and reliably adjusted.

In the above embodiment, the headbox is divided into three parts, but it is also possible to divide the headbox into two parts and install both headboxes 9a and 9b vertically apart, as shown in FIG. 2, or to divide the headbox into four or more parts. .

Effects As detailed above, this invention divides the head boxes 2a, 2b, 2c in the longitudinal direction, and installs the head boxes 2a, 2b, 2c vertically apart. It has the excellent effect of being able to adjust the lighting from below and to the sides with a single blind.
