Description

[Detailed Description of the Invention] [Industrial Application Field] The window of the present invention relates to a blind that is attached to glass or the like and blocks external light entering a room through the window.
To provide a blind that can be attached to an existing single sash with a particularly simple mechanism and can obtain the same heat insulation effect as a double sash with a built-in blind.

[Conventional technology]

Recently, we have increased the heat insulation effect as well as the light blocking effect,
In order to achieve the purpose of energy saving, various double sashes with a built-in blind have been proposed, in which a blind is built inside the double sash.

[Problem that the invention seeks to solve]

Although such a sash with a built-in blind is convenient and has a certain practical effect, it is extremely expensive and cannot be easily applied in places where conventional sashes, that is, single-layer sashes, have been installed. It is impossible to do so, and if you want to install a sash with built-in blinds, you will have to change the structure of the window itself.

The present invention solves the drawbacks of the conventional double sash with a built-in blind as described above, can be easily attached to a conventional single sash at low cost, and can be made into a double sash with a built-in blind.
The purpose of the present invention is to provide an innit type blind that can be installed by stacking a plurality of blinds according to the dimensions of the window.

[Means for solving problems]

The present invention solves the problems with conventional double sashes with built-in blinds by integrally forming narrow protruding plates that protrude in the horizontal direction on one side of the upper and lower edges of a rectangular flat plate made of a transparent material. A unit blind is constructed by arranging a plurality of shielding plates having a width approximately equal to the width of the upper and lower protruding plates at equal intervals between the upper and lower protruding plates. To provide a unit type blind characterized in that each piece is attached to a window surface.

This unit-type blind is equipped with an angle change mechanism that changes the angle of the shielding plate from a horizontal position to a vertical position, making it possible to adjust the light shielding. By providing means for interconnecting the angle changing mechanisms of the blinds, the light shielding plates of all unit blinds can be operated simultaneously at one location.

〔Example〕

The present invention will be described below based on embodiments shown in the drawings.

FIG. 1 is a cross-sectional view showing the blind of the present invention attached to glass. In the figure, 1 indicates the unit blind of the present invention, 2 indicates the sash frame, and 3 indicates the glass.

As shown in Fig. 2, the unit blind 1 includes a rectangular flat plate 1a made of transparent synthetic resin, etc., and narrow protruding plates 1b, 1b protruding in the horizontal direction, integrally formed on one side of the upper and lower edges. However, a plurality of shielding plates 1c having a width approximately equal to the width of the upper and lower protruding plates are arranged at equal intervals between the upper and lower protruding plates.

Unit blind 1 configured as above
By attaching a plurality of sashes to the window surface according to the dimensions of the window, a double sash with a built-in blind can be constructed as a whole. In the illustrated example, a fixing member 1d such as an adhesive tape or a suction plate is attached to the tips of the upper and lower protruding plates 1b, 1b of the unit blind 1, so that the unit blind can be attached to the window surface. Alternatively, tension members may be provided on both sides of the unit blind and the unit blind may be tensioned and fastened between the window frames.

The shielding plate 1c may itself be made of an opaque light-shielding material, or, as shown in FIG. Blind slats 4
may be placed. Also, as shown in Figure 4,
The blind slats 4 may be supported by support cords as in normal horizontal blinds.

In the unit type blind described above, light shielding can be adjusted by providing an angle changing mechanism that changes the angle of the shielding plate from a horizontal position to a vertical position. An embodiment of such an angle adjustment mechanism is shown in FIGS. 4 and 5, A and B.
Similar to conventional horizontal blinds, the shading plate 4 is supported by a ladder-like support cord 6, and one of the vertical cords is wound around a drum 7 in the head box to adjust the angle of the shading plate. Adjust. Figure 5 A shows the light shielding plate horizontally. FIG. 5B shows a state in which the light shielding plate is tilted.

Furthermore, as a means for interconnecting the angle changing mechanisms of a plurality of unit blinds attached to a window, as shown in FIG. are provided, and by interconnecting them, the shielding plates of all unit blinds can be operated by rotation of the drum 7.

Figures 6A and 6B show modifications of the angle adjustment mechanism of the shielding plate. In this system, a blind slat 4 is arranged on a plurality of shelves formed integrally with a flat plate 1a, and one end of the blind slat 4 is pivotally connected to a movable arm 8 that can be slid up and down.
By moving this movable arm 8 up and down, the angle of the shield plate is adjusted. Connecting portions 8a are provided at the upper and lower ends of the movable arm 8, so that the movable arms of a large number of unit blinds can be connected in sequence.

Since the present invention has the above-mentioned structure, it can be attached to an existing single-layer sash with a simple mechanism, and the shielding plate is placed within the double structure of the window glass and rectangular flat plate, which improves the heat insulation effect. Excellent blind built-in double sash can be easily formed.
In addition, a plurality of unit blinds can be attached depending on the size of the window to form a double sash that covers the entire window, which has a great practical effect.

In addition, by providing a simple angle adjustment mechanism and its connection mechanism, it is possible to provide a blind in which each unit can be operated at the same time.
