Description

[Detailed description of the invention]

[0001]

[Technical field to which the invention belongs]

 The present invention relates to a sheet for a window glass which is used by being attached to a surface of a window glass in order to improve a heat insulating effect of a room.

[0002]

[Prior art]

 Various types of window glass sheets of this type have been proposed in the past, but only in the form of a thin film, and two thin films are superposed and an air chamber is interposed between them. (Air layer) is basically classified. However, the former, which is only formed in a thin film form, is likely to be wrinkled when pasted on the surface of the window glass and is difficult to attach, and there is no air layer between the window glass sheet and the window glass surface. There is a problem that an effective heat insulation effect cannot be expected. In the latter case where the two thin films are laminated and an air chamber (air layer) is formed between them, the heat insulation effect is not obtained when the air chamber is sealed. However, if the air chamber was partially opened, the insulation effect could not be expected so much, and the appearance and transparency were poor and the cost was high.

[0003]

[Problems to be solved by the invention]

 The present invention has been made in view of such conventional inconveniences, and it is expected that an excellent heat insulating effect can be expected, and that the present invention can be simply and beautifully stuck to the surface of a window glass, and can be manufactured at a low cost. The aim is to provide a sheet for window glass that can be used.

[0004]

[Means for Solving the Problems]

 A window glass sheet according to claim 1 of the present invention that achieves the above object is a square-shaped plastic sheet formed by swelling at least a portion other than the four peripheral edges from the four peripheral edges to form a sheet with the back surface of the plastic sheet. The feature is that an air layer chamber is formed between the window glass surface. In addition, the window glass sheet according to claim 2 of the present invention has a plurality of hills bulging and forming on a portion other than the four peripheral edges of the plastic sheet formed in a square shape, and the back surface of the hill and the window glass are formed. It is characterized in that an air layer chamber is formed with the surface.

[0005]

[Embodiment of the invention]

 Hereinafter, specific preferred embodiments of the present invention will be described in detail with reference to the drawings. However, the present invention is not limited to the illustrated embodiments, and various variations are conceivable.

The plastic sheet 1 is made of a transparent or translucent plastic material such as polystyrene, polyethylene, or polycarbonate, and is formed into a thin sheet having a thickness of, for example, about 0.3 mm to 1 mm. It is formed in a square shape having an appropriate size of about 300 mm to 900 mm according to the size. In this case, the sheet may be formed in a square shape having the same width and height, or may be formed in a rectangular shape having different widths and heights. Or an appropriate color.

[0007] Then, at least a portion other than the four peripheral edges 2 of the plastic sheet 1 is formed so as to bulge out from the four peripheral edges 2 to form the hill portion 3, and the hill portion 3 is formed between the rear surface of the plastic sheet 1 and the window glass surface 4. The air layer chamber 5 is formed between them. That is, all parts other than the four peripheral edges 2 of the plastic sheet 1 are swelled in a hill shape, and one hill portion 3 is formed on one plastic sheet 1, and the back surface of the plastic sheet 1 is formed. Or a single air layer chamber 5 is formed between the glazing surface 4 and a plurality of hills 3 formed by bulging out a portion other than the four peripheral edges 2 of the plastic sheet 1. A plurality of air space chambers 5 are formed between the back surfaces of the plurality of hills 3 and the window glass surface 4.

In the embodiment shown in FIGS. 1 and 2, portions other than the concave ribs 6 formed at appropriate widths at equal intervals in the vertical and horizontal directions with the four peripheral edges 2 of the plastic sheet 1 are used. By bulging into a flat hill, a number of hills 3 are formed in one plastic sheet 1 in an orderly manner, and an air chamber is formed between the back surface (inside) of each hill 3 and the window glass surface 4. 5 are formed.

In this case, there is no particular limitation on the width of the concave ribs 6 and the shape, size, number, etc. of the hills 3, but in the illustrated embodiment, the width a of each concave rib 6 is formed to be the same. At the same time, each hill 3 is formed in a square having the same size, and the width a of each concave rib 6 is formed slightly larger than the width b of the four peripheral edges 2. By forming in this manner, when arranging a plurality of plastic sheets 1 on one window glass and pasting them, a part of adjacent plastic sheets 1 can be easily overlapped with each other, and at the same time, the size can be reduced. It is possible to cope with different types of windows only by overlapping a part of the plastic sheet 1 without cutting it, and even if the plastic sheet 1 is cut, the concave rib 6 can be used. This makes it easy and convenient to cut along the edge of the window glass and paste it on the window glass with good appearance. It should be noted that it is not preferable to form the hills 3 so much that the number of the hills 3 increases as the volume of the air space chamber 5 decreases and the heat insulation effect of the entire sheet decreases.

When the plastic sheet 1 is attached to the window glass 4, an adhesive is applied to the four peripheral edges 2 of the plastic sheet 1 and the back surface of each concave rib 6 in advance or on site. Alternatively, a double-sided adhesive tape may be applied and pressed against the surface of the window glass 4.

[Effect of the invention]

 In the window glass sheet of the present invention, at least a portion other than at least the four peripheral edges of the rectangular plastic sheet is bulged out of the four peripheral edges, and air is blown between the rear surface of the plastic sheet and the window glass surface. Because it is configured to form a stratified chamber, the existence of a sealed air stratified chamber formed between the back surface of the plastic sheet and the window glass surface is expected to exhibit an excellent heat insulating effect. Can

Moreover, unlike the film-like sheet, at least a portion other than at least the four peripheral edges of the plastic sheet formed in a square shape is swelled from the four peripheral edges, so that the sheet is given rigidity, and thus the sheet is formed. It is easy to handle without sticking when attaching to the windowpane surface, and it is possible to paste it on the surface of the windowpane easily and in a good format. This effect is more remarkable by forming a plurality of hills on the plastic sheet other than the four peripheral edges.

Further, the sheet for window glass according to the present invention is formed of one plastic sheet unlike a sheet in which two film-like sheets are overlapped to form an air chamber (air layer) therebetween. Therefore, it can be manufactured and provided at low cost.
