Abstract

The invention provides an improved color-changing hollow shutter which comprises a window frame, wherein outer layer glass and inner layer glass are fixed in the window frame, and a hollow interlayer is formed between the outer layer glass and the inner layer glass; a blind curtain is arranged in the hollow interlayer, and the louver blades of the blind curtain are driven by a driving mechanism on the window frame to turn over; the louver blades are composed of transparent sheets provided with ultraviolet isolation films, and the inner layer glass is composed of photochromic glass. The shutter can not only adjust the shading quantity of the window, but also does not shield the visual field.

Description

Improved color-changing hollow shutter

Technical Field

The invention relates to the field of doors and windows, in particular to a louver.

Background

The hollow shutter is a popular window body and mainly comprises a window frame, an inner layer glass and an outer layer glass; a larger space is formed between the inner layer glass and the outer layer glass, and a shutter curtain is arranged in the space; thereby the shutter curtain and the window body are integrated into a whole, and the dragging encumbrance of the external curtain is avoided.

As is well known, before the blind is completely pulled up, the louver blades must be adjusted to be horizontal, which is troublesome; therefore, the blind is usually not completely pulled up during the use process, but only the inclination angle of the louver blades is adjusted, but the problem is faced that even if the louver blades are adjusted to the most transparent inclination angle, the view is still obviously blocked.

Disclosure of Invention

In view of the above problems, an object of the present invention is to provide an improved color-changeable hollow blind, which can not only adjust the amount of light blocking of a window but also does not block the view.

The technical scheme adopted by the invention for solving the technical problems is as follows: the improved color-changing hollow shutter comprises a window frame, wherein outer-layer glass and inner-layer glass are fixed in the window frame, and a hollow interlayer is formed between the outer-layer glass and the inner-layer glass; a blind curtain is arranged in the hollow interlayer, and the louver blades of the blind curtain are driven by a driving mechanism on the window frame to turn over; the louver blades are composed of transparent sheets provided with ultraviolet isolation films, and the inner layer glass is composed of photochromic glass.

Preferably, the transparent sheet of the louver is also formed of a photochromic glass sheet.

The invention has the beneficial effects that: when the improved color-changing hollow shutter is used, if external illumination is strong and good shading needs to be formed, the inclination angle of the shutter blades can be adjusted, so that the external illumination can penetrate through the shutter and directly irradiate on the inner glass, and at the moment, the inner glass is basically fully irradiated by ultraviolet rays, so that the inner glass can be completely blackened like sunglasses; when needs keep good permeability to in the time of observing the outdoor scene, then adjust the shutter plate to the vertical state that tends to, at this moment, outside illumination just can shine on inlayer glass after passing the ultraviolet barrier film on shutter plate surface, and the ultraviolet ray is by the complete filtering this moment, and inlayer glass no longer discolours, thereby makes whole window keep the complete transparent state, and the printing opacity is good, and the field of vision does not shelter from, can be called completely wonderful.

Detailed Description

The invention is further illustrated with reference to the following figures and examples:

in the first embodiment shown in fig. 1 and 2, the improved color-changing hollow blind includes a window frame 1, wherein an outer layer glass 21 and an inner layer glass 22 are fixed in the window frame 1, and a hollow interlayer 3 is formed between the outer layer glass 21 and the inner layer glass 22; a blind is arranged in the hollow interlayer 3, and the louver blades 41 of the blind are driven by a driving mechanism (standard component, not shown) on the window frame 1 to turn over; the louver 41 is formed of a transparent sheet having an ultraviolet barrier film, and the inner glass 22 is formed of photochromic glass, i.e., is black when irradiated with ultraviolet rays.

When the improved color-changing hollow shutter is used, if the external light is strong and good shading needs to be formed, the inclination angle of the louver blades 41 can be adjusted, so that the external light can pass through the shutter and directly irradiate on the inner layer glass 22, namely, as shown in the state of fig. 1, at this time, the inner layer glass 22 is basically fully irradiated by ultraviolet rays, and the inner layer glass 22 can be completely blackened, like a sunglass. In fig. 1, it is illustrated that external light passes through the interval between two louvers 41, and after the external light is irradiated onto the inner glass 22, the area irradiated by the light between the two louvers 41 is changed into black, because the louvers 41 are very thin, generally only 0.2mm to 0.4mm, and the maximum thickness is not more than 1mm (in fig. 1, the louvers are illustrated as being thick), the blind can basically consider that there is no light shielding for the inner glass 22, that is, the black colored blocks in fig. 1 can be paved on the whole inner glass 22.

When the good permeability needs to be kept so as to observe an external scene, the louver blade 41 can be adjusted to be inclined to the vertical state, as shown in fig. 2, at the moment, external illumination can irradiate the inner-layer glass 22 after passing through the ultraviolet isolation film on the surface of the louver blade 41, ultraviolet rays are completely filtered, the inner-layer glass 22 does not change color any more, and therefore the whole window is kept in a full-transparent state, light transmission is good, and the visual field is not shielded.

It is worth mentioning that the louver, even in the fully shaded state, does not strictly completely prevent light from passing through, but rather means that the entire inner glass 22 is dark like sunglasses; at this time, people in the room can see the outside, but outside people can hardly see the room.

In fact, in daily use, the blind is normally in between the two states mentioned above, namely between the fully shaded and the fully transparent states; the state of the inner glass 22 is shown in fig. 3, and is composed of a plurality of equally spaced dark stripes 5 corresponding to the black color blocks in fig. 1; the dark stripes 5 are thickened or narrowed with the change of the inclination angle of the louver blades 41, and can be gradually thickened from a narrow state to a basically disappeared state to a state that the dark stripes are paved on the whole inner glass 22 together, thereby realizing the continuous adjustment of the luminous flux of the window and being full of interest.

In addition to the first embodiment, the transparent sheet of the louver 41 may be made of photochromic glass. In this case, when the inclination angle of the louver blade 41 is adjusted, part of the illumination can be directly projected to the side of the louver blade 41 without the ultraviolet isolation film, at this time, the louver blade 41 turns black, and meanwhile, the equidistant dark stripes are formed on the inner layer glass 22, so that dark stripes with depth of field are formed between the inner layer glass and the outer layer glass of the whole window, and the artistic expression forms are rich; meanwhile, the function of the first embodiment is completely included when the side of the louver 41 not provided with the uv-blocking film is not directly illuminated (the louver 41 may be turned by 180 °).

The above description is only for the purpose of illustrating the preferred embodiments of the present invention and is not to be construed as limiting the invention, and any modifications, equivalents, improvements and the like that fall within the spirit and principle of the present invention are intended to be included therein.
