JP2000356081A - Paper blind for window - Google Patents

Abstract

PROBLEM TO BE SOLVED: To facilitate fitting and handling, to prevent dew condensation, and to enhance the heat insulating performance by folding down both ends of either short or long side of Japanese paper of a prescribed area by a prescribed length, folding it into a bellows shape in the direction of setting the folded-down parts to the both ends, and spreading it after forming folds. SOLUTION: Both long sides 4 of Japanese paper 1 of the width approximately 80 cm and the length approximately 1 m 30 cm for a wind frame of the width 80cm × height 75 cm in the inside diameter are folded down 2 by the width approximately 1-2 cm, then it is folded 3 at regular width of approximately 1-3 cm in the long side direction into a bellows shape a plurality of times, made to form folds tightly, and spread. The Japanese paper can be thus used for a blind for a window. When it is used as a lateral type, it has the stability and can stand alone, because the horizontal cross section becomes zigzag. The stability can be enhanced by fixing respective side ends of the circumferential sides with fixing tools for a window frame. This structure can facilitate the handling, etc., improve the heat insulating performance, and prevent the dew condensation by the air inclusiveness and hygroscopicity of the Japanese paper.

Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a window blind.

[0002]

2. Description of the Related Art In general blinds, thin small pieces of hard paper or aluminum material are connected by a thread, and the small pieces are opened and closed and bound by manipulating the thread. When this is set on the window,
Although it is excellent in aesthetics and lighting, it is not enough to keep the room warm and dew condensation on the window glass cannot be prevented. On the other hand, setting of the curtain requires time and effort.

[0003]

The object of the present invention is to use a material which is easy to install and handle, and which prevents condensation on windows and has a heat retaining effect.

[0004]

Means for Solving the Problems A Japanese paper having a predetermined area is made to have a short diameter,
The window blind is folded by 1-2 cm at either end of the major axis, folded in a bellows-like manner a plurality of times in the direction in which the folded portion is located at both ends, and once given a habit, then expanded to have the function of a window blind.

DESCRIPTION OF THE PREFERRED EMBODIMENTS Embodiments of the present invention will be described with reference to the drawings based on embodiments. 80cm wide and 75cm high for window frame 6 about 80cm wide and about 1m30 long
cm Japanese paper 1 is folded in both major diameters 4 with a width of about 1 to 2 cm 2 and then folded several times in the major diameter direction with a regular width of about 1 to 3 cm 3 in a bellows-like manner. Spread. This state is shown in FIG. When using this as a window blind, horizontal and vertical types can be considered,
1 is a horizontal type, and FIG. 2 is a vertical type. In the case of the horizontal type, the cross section in the horizontal direction is zigzag and stable, and can stand on its own if there is no wind. When the window frame 6 is vertically elongated, a Japanese paper having a predetermined size may be folded in the minor axis 5 direction.

[0006] In FIG.
It is a set. When the window frame 6 is small (for example, about 80 cm wide × 75 cm high), one set is sufficient. Since the Japanese paper 1 has a zigzag cross section by folding it in a bellows shape 3, it rises even as it is, but in order to make it more stable, it is small at two places at each side end 8 around the blind and several places at each upper end 7. A fixing device 9 for a window frame, such as a lightweight suction cup or a double-sided tape, is fixed, and a small magic tape 10 is fixed to each end of the central portion, and both ends are joined. Alternatively, as shown in FIGS. 6 and 7, in order to stabilize the rising of the blind, for example, a fixing tool such as a nail is attached to the window frame 6 without fixing the fixing tool to the blind itself. There can be a situation where you just stand in the middle. As shown in FIG. 5, in a state where the Japanese paper 1 is folded, a diameter of 5 mm is provided at two places at both ends.
When a light round bar 15 having a smooth surface with a diameter of about 3 mm is inserted into the hole 14, a smooth opening and closing is achieved. This can be applied to a vertical type described later.

[0007] In FIG.
It is a set. When the window frame 6 is small (for example, about 80 cm wide × 75 cm high), one set is sufficient. When two perforated fixing devices 12 are fixed to each upper end portion 11 of the Japanese paper blind and are hung on projections 13 attached to the window frame 6 at equal intervals with the fixing devices 12, the blinds hang down by their own weight. If not, add some weight. When the projection 13 cannot be driven into the window frame 6, a fixing tool such as a suction cup or an adhesive tape is fixed.

[0008]

The features of the paper blind of the present invention are enhanced when Japanese paper is used as the material. That is, it is inexpensive (easy to produce), lightweight, easy to install and remove, environmentally friendly even when discarded, surprisingly durable, has a moderate brightness and feels like a shoji, and the surface is easily colored and designed. You can decorate and so on. In terms of heat retention, in addition to the air inclusiveness of the Japanese paper itself, the surface is large and uneven, and there are many stationary air layers between the window glass. It also prevents condensation on the glass. Multiple layers can further increase the heat retention effect. Therefore, it is particularly effective for windows on the north side in winter.
