BACKGROUND OF THE INVENTION US Pat. No. 4,989,955
No. 2 relates to a window material for deflecting the light path of solar radiation, by irradiating the solar radiation indoors by deflecting the solar radiation indoors by forming a series of mutually parallel grooves on the surface of the organic glass plate by laser beam irradiation or the like. There is disclosed a window material having an energy-saving effect, such as saving energy, or shielding sunlight to reduce a cooling load. However, it is not sufficient in that the window material is provided with a decorative property and a design property, and is not much different from a case where a light reflective blind slat is simply attached to the window material and the slat is fixed.

[0003] Incidentally, in the case of a double-glazed glass, a lattice or a honeycomb structure is inserted to aim at designability, light deflecting property, moderate transparency, and concealing property. It is not low cost.

[0004] The present invention differs from the above-mentioned known examples in that decorativeness,
An object of the present invention is to provide a window material that is rich in design, has excellent light deflection properties, is technically easy, and can be formed without any trouble.

SUMMARY OF THE INVENTION The present invention relates to a window material made of transparent glass used for an opening of a building or the like to guide solar radiation to the indoor side or reflect it to the outdoor side. A large number of corrugated grooves are formed on the surface of the inorganic glass plate at appropriate intervals, and the corrugated grooves penetrate or penetrate the glass plate surface in the direction perpendicular to or inclined to the glass plate surface in the thickness direction. A non-penetrating groove, the window material was scanned by irradiating a laser beam as a means for forming a wavy groove, and a light-reflective paint was permeated and applied to the wavy groove. , In addition, an inorganic glass plate is attached to one or both surfaces on which the corrugated grooves are engraved,
Consists of

[0006] Thus, while the grooves themselves exhibit decorativeness and design, the light path of the solar radiation is deflected, that is, the direction of the light is changed by the action of reflection, refraction, etc., and the light is made to enter the interior of a building or the like. In addition, the present invention has the effect of reducing the amount of illumination, or reflecting and blocking solar radiation to reduce the cooling load in summer.

DESCRIPTION OF THE PREFERRED EMBODIMENTS The present invention will be described below based on an embodiment.
In the accompanying drawings, FIG. 1 is a schematic front view of the present invention, FIG. 2 is a partial front view according to another embodiment, and FIGS. 3A and 3B are cross-sectional views taken along line X-X of FIG. FIG. 3 is a diagram illustrating a deflection optical path. 4A to 4C are partial front views illustrating a wave pattern.

In the front views of FIGS. 1 and 2, reference numeral 1 denotes a window material, and in this embodiment, reference numeral 2 denotes a glass plate made of, for example, an acrylic resin in which grooves 3 are formed. The glass plate may be another organic glass such as polycarbonate or a soft inorganic glass such as high lead glass. Although the thickness of the glass plate is not specified, the thickness is preferably several mm or more in order to effectively deflect the light, and is preferably about 20 mm or less in consideration of handleability and the like. A colored glass plate may be used as long as it is transparent, but a clear glass plate should be used for the purpose of the present invention.

The corrugated shapes of the corrugated grooves 3, 3 are not specified. In FIG. 1, the corrugated grooves are sinusoidal grooves, and in FIG. 2, the corrugated grooves have a turtle-shaped design pattern as a whole. However, the present invention is not limited to this, and various means such as grooves obtained by scanning various corrugated shapes by physical etching means can be adopted. In the drawing, the laser beam is scanned by a carbon dioxide gas laser as an example, but the laser beam can be formed by other laser light. Alternatively, when the piercing tool is scanned by a water jet or appropriately, the side surfaces (4 and 4 in FIG. 3A) of the groove become rough, and the light incident on the portion is scattered to simply exhibit irregular reflection. The part is etched with an erosion liquid to make a smooth surface.

[0010] Alternatively, in the case of organic glass, a large number of corrugated strips corresponding to the grooves are provided at appropriate intervals on the upper or lower surface of the flat box-shaped form when producing the uncured resin liquid. And after curing, the mold and the corrugated strip are removed by mold release.

As described above, as shown in the cross-sectional view of FIG. 3A, if the grooves 3, 3 are parallel to each other and their side surfaces 4, 4 are smooth surfaces, the optical path deflection in a specific direction will not occur. It becomes possible. The width of the grooves 3, 3 may be about 0.1 mm to about 0.4 to 0.5 mm, but may be appropriately designed in consideration of designability, etc., and the distance between one groove and an adjacent groove. The thickness may be appropriately designed such that the thickness is about 1/2 of the glass plate thickness or exceeds the plate thickness. Further, these grooves may be penetrated to the back surface side, but need not be penetrated as shown in the figure.

An inorganic glass plate 5 is adhered to the groove-formed surface of the glass plate 2 having the groove formed thereon with an acrylic or other appropriate adhesive, or 5 '( As shown by a broken line), an inorganic glass plate can be attached. The attachment of the inorganic glass plate is preferable in order to reinforce the glass plate 2 and to prevent dust from entering the grooves 3.

In the drawing, reference numerals 6 and 6 represent light (solar radiation) intrusion paths, and a normal intrusion path, which is indicated by a broken line 7 and a groove 3.
In this embodiment, the light is reflected and enters the room upward. In the case of a groove having a large number of horizontal lines in the pattern as shown in FIG. 2, the upward or downward deflection in the light intrusion direction is mainly performed. However, for the purpose of the present invention, by deflecting upward, natural light can be taken deep inside the room.

The angle of the groove in the sheet thickness direction with respect to the glass sheet surface 2 may be a right angle, but may be inclined.
Depending on the relationship between the incident angle of the solar radiation 6 and the side surface 4 of the groove, it is possible to appropriately enter the room or shield the light. Of course, it is also possible to adjust the incidence and light shielding by rotating the window material itself up and down or further left and right. Needless to say, the running line on the plate surface of the grooves 3, 3 may be horizontal, vertical, or oblique.

For example, in the corrugated groove 3 shown in FIG. 1, the running line on the plate surface is horizontal, but as a whole, the line Y-Y
Direction, line Since the ratio of groove lines running obliquely in the Z-Z direction is large, light reflected and deflected by the Y-Y line and the Z-Z line increases.

FIG. 4 is a partial front view illustrating a part of another corrugated groove. In FIG. 4A, the grooves 3, 3 have a honeycomb-like or tortoise-like shape similar to FIG.
FIG. 4C shows that the grooves 3 have a lattice shape by vertical and horizontal lines.
Each of the grooves 3 and 3 has a rosary shape, and each of them can exhibit an elegant design. Of course, the wave pattern is not limited to this, and it goes without saying that various designs can be made.

As shown in FIG. 3A, the light 6, 6 incident on the window material 1 is reflected by the groove side surfaces 4, 4, and if the incident angle is larger than the critical angle, it is indicated by arrows 6 ', 6'. With such partial refraction, the refracted light repeatedly scatters reflection and refraction between the glass and air layers. On the other hand, as another mode in which the light deflecting property is further enhanced, if a known light-reflective paint 8 such as a known white or silver-white paint or a metallic paint is penetrated and applied in the groove, it is shown in FIG. 3B. As described above, the light reflectivity on the groove side surfaces 4, 4 is increased, and the deflection is further improved.

Further, the groove design is clearly evident, the design is further enhanced, and the paint also acts as an adhesive, so that it is effective for reinforcing the glass plate.

As the paint 8, for example, titanium oxide,
Polyester-based, epoxy-based, urethane-based resin coatings containing metal aluminum or the like can be employed. As a coating method, the surface of the glass plate 2 other than the groove is masked and the paint is cast and applied. Alternatively, the paint is cast and applied to the entire surface of the plate and then the paint adhered to the plate surface is wiped off, or Further, known means such as polishing and removing the paint adhered to the plate surface can be adopted.

It is needless to say that the present invention can be used not only as a window material but also as a lamp cover and interior decoration.

[Effects of the Invention] According to the present invention, the design of the groove itself is exhibited, and at the same time, the light path of the solar radiation is deflected so as to be incident into the interior of a building or the like, thereby reducing the amount of illumination or reflecting the solar radiation. The effect of reducing the cooling load in summer by shielding the light is exhibited, and the effect is remarkably improved by applying a light-reflective paint.
