Description

Window blind with bent blades to save energy by introducing natural light {Window Blind with bent blades}

The present invention relates to a blind having a bent blade. More specifically, it relates to a bent blind that can be bent by the blade of the blind to block the direct sunlight and the eyes of the outside while at the same time introducing the external natural light into the room to improve the indoor environment.

Usually, openings are made and glass is installed in the openings for natural light in the building and for a pleasant environment in the room. Blinds are installed to block direct sunlight coming in through the glass and people's eyes or to adjust the degree of light in the room. By installing the plurality of blades side by side horizontally or vertically, to adjust the inclination of the plurality of blades or to move the plurality of blades up and down or left and right to adjust the degree of light in the room.

1 is an embodiment of the installed shanghai blinds that are commonly used. The blinds are fixed parts (1) fixed to the wall surface or the upper window, a support plate (2) installed on the bottom, a plurality of blades (3) installed side by side up and down between the fixing part (1) and the support plate (2) A pair of end straps 6 surrounding the outer side surfaces of the ends of the support plate 2 and the plurality of blades 3 and connected to the fixing part 1, and a predetermined interval in the width direction of the end straps 6 and the blades It is connected to each of the plurality of auxiliary straps (7) on which the blade is placed, connected to the pair of end straps (6) and installed on one side of the fixing portion (1) angle adjustment rod (8) to adjust the inclination of the blade Passing through the inner surface of the one end portion of the plurality of blades (3) through the interior of the fixing part 1 and again through the inner surface of the other end of the plurality of blades (3) through the interior of the support plate (2) Connecting strap (9) for tying the fixing part (1) and the support plate (2) and the blade and the connecting strap (9) is connected to the support plate (2) and Consists of a height adjustment strap 10 to move the blade 3 up and down. Therefore, by pulling the height adjustment straps 10, the connecting straps 9 can be pulled or unrolled to adjust the height of the blinds. When the angle adjustment rod 8 is rotated, the pair of end straps 6 is up and down. You can adjust the tilt of the blade as it moves to.

The side rail-type blinds of FIG. 2 are provided with rails on a fixed part 1 fixed to a wall or an upper window, and a plurality of blades 3 are installed in the rail in a vertical direction. Unlike the shanghai-type blinds, the blade is unfolded and folded while being moved to the left and right to adjust the inclination of the vertical blade while rotating the angle adjusting rod (8).

These blinds are equipped with sensors to adjust the tilt of the blade while operating the remote control, or recognize the sun's altitude by time and rotate the blade every time to adjust the light beam.

The blade of the conventional blind as described above has a curved shape in order to give rigidity to the conventional blade. If blinds are spread out vertically or horizontally to the front of a window or glass door to block the eyes of the outside or to avoid direct sunlight on the work surface, and the blades are placed vertically, natural light entering the room is blocked by blocking the window or the glass door. There is a problem that must be used for artificial lighting.

Since the blinds are uniformly blinded to block direct sunlight from the blinds, they are wasting energy because they have to be illuminated by artificial lighting inside the office even though the outside is very bright. If you can introduce reflected natural light into the room, you can save a lot of waste of electricity for artificial lighting.

In the conventional blind blades, there was no means for introducing or blocking external light rays as needed while blocking external eyes, and thus blinds were used for the purpose of blocking the eyes or direct sunlight. The inventor has made the present invention to solve the problems that the conventional blinds.

It is an object of the present invention to provide a blind having a bent cross-section blade that can block natural eyes and direct sunlight by bending the blades of the blinds, but allow natural light to flow deep into the room.

Another object of the present invention is to provide a blind having a bent cross-section blade that can effectively introduce natural light into the room by using a bent blade reflector to reduce the cost for artificial lighting.

Another object of the present invention is to provide a blind that can reduce artificial lighting by introducing reflected natural light into the room.

It demonstrates in detail according to drawing of the specific example of this invention.

3 and 4 are cross-sectional and perspective views of an embodiment of a blade forming a bent blind of the present invention.

The bent blinds are the same as those of the shanghai or side rail blinds as the general blinds described above, but differ in the shape and surface treatment of the blind blades.

The blade of the bent blind of the present invention is composed of a first blade (4) and a second blade (5) that is bent at an angle to one edge. The blade is formed such that one blade is bent in the width direction so that the first blade 4 and the second blade 5 have a fixed angle to each other.

In the upper surface A and the lower surface a of the first blade 4, the upper surface is treated as a reflective surface and the lower surface is treated as a non-reflective surface, and the upper surface B and the lower surface of the second blade 5 are b. When treated with a reflective or non-reflective surface, by adjusting the overall angle of the blind blade of the present invention, the incident natural light can enter the reflected natural light deep inside the room through a multi-step reflection process.

When the inclination of the blade is properly adjusted with the angle adjusting rod, the light rays incident between the first blade 4 and the second blade 5 are separated from the upper surface A or the second blade 5 of the first blade 4. Reflected by the upper surface (B), natural light flows into the room and is blocked by the first blade 4 from the outside line of sight.

The cross section of the first blade 4 and the second blade 5 is a planar cross section in this embodiment, but when the width of the blade is large or the length is insufficient, the cross section is bent to give rigidity to the middle or end of each blade. You can put wealth.

In order to efficiently introduce natural light, a sensor that can automatically rotate the blade of the blind can be mounted in place of the angle adjusting rod manually adjusted. When the sensor recognizes the sun's altitude that changes with time and rotates the blade blade according to the sun's altitude every certain time, natural light can be efficiently introduced into the indoor space.

5 and 6 are cross-sectional views and perspective views of another embodiment of a bent blind blade of the present invention, wherein the blade is formed by connecting two first blades 4 'and a second blade 5'. . End straps 6A 'contacting both ends of the first blade 4' with end straps 6A 'and 6B' at both ends and other end straps 6B 'contacting both ends of the second blade 5'. Since the inclination of the first and second blades (4 ', 5') can be adjusted by the first and second angle adjustment rods respectively connected to each other, the angle between the first and second blades can be freely adjusted.

Reflective or non-reflective surface treatment on the upper and lower surfaces of the first blade 4 'and the second blade 5', and the middle of the cross section at the cross sections of the first blade 4 'and the second blade 5'. Naturally, the end portion can be bent to reinforce rigidity.

7 is a modification of the present invention is a reflection or non-reflective surface treatment on the upper and lower surfaces of the existing arc-shaped blind blade. Natural light is introduced into the room even in a blind with a conventional blind blade by subjecting the upper surface A and the lower surface (a) of the first wing part to the upper surface B and the lower surface (b) of the second wing part. You can.

By bending the blade of the bent blind of the present invention or by connecting two divided surfaces to form an angle, the gaze and direct sunlight are blocked, but the reflected natural light can be introduced deep into the room. In addition, the use of reflective material as a blind blade can reduce the cost for artificial lighting because direct sunlight is reflected in several stages and can be introduced into the room to effectively light natural light.
