The present invention relates to a sunshade, and more particularly to a sunshade for adjusting the amount of solar radiation flowing into the room.

In general, as the use of curtain walls in buildings increases, the heating and cooling loads through the skin are greatly increased. In particular, in consideration of visual openness in the office space, the glass use area in the outer cover is greatly increased, the indoor inflow of direct sunlight through the summer glass has a great influence on the cooling load.

In addition, since solar radiation is introduced into the room through glass, glare from the excessive brightness difference occurs in indoor spaces.In most buildings, blinds are installed indoors to block the inflow of solar radiation and use lighting equipment during the day. have.

Recently, as interest in energy saving and indoor environment has increased, various methods in terms of architectural planning such as reduction of external aperture ratio, window planning according to azimuth, and installation of sunshade to reduce the effects of heating and heating load and indoor environment caused by such solar radiation Are being applied. However, in office buildings, the reduction of the external aperture ratio and the planning of the window according to the orientation are inevitably limited in terms of design, and thus the solar radiation flowing into the room is controlled through the blinds.

In this way, when the awning device is installed indoors, the occupant can be arbitrarily operated and easy to maintain, but in order to reduce the heating and cooling load due to the solar in terms of energy saving, it is advantageous to install the awning outside. For example, according to an existing study analyzing the effect on the cooling load of a building by applying an external awning, such as a fixed sunshade, it can reduce the cooling load by about 23% when an external awning is installed southward. Able to know.

However, since the sun angle introduced into the room varies depending on the altitude of the sun, it can be seen that the fixed shade device alone has a limitation in controlling the heat gain of the room due to direct solar radiation. That is, when the sun is high or the amount of insolation is large, the slat angle of the sunshade should be adjusted directly by using a manual operation or a driving device. It causes an increase in manufacturing cost.

 Therefore, to solve this problem, it is necessary to adjust the amount of inflow into the room according to the external climatic conditions and the altitude azimuth condition of the sun. In other words, in order to control the amount of solar radiation flowing into the room, it is necessary to improve physical properties such as structure and shape of the slat, installation location, reflectance, transmittance, and emissivity. In particular, in order to save energy in buildings and improve the indoor environment, technology development regarding slats of sunshade devices such as blinds is required more.

The slats 10 are formed in a plate shape which is arranged in a horizontal direction with respect to the glass window, and are arranged at regular intervals along the vertical direction. The configuration of the slats 10 will be described later with reference to FIG. 2. Shall be.

The support member 30 is for adjusting the spacing between the slats 10 while supporting the slats 10, and is installed to be connected to both edge portions of the slats 10, and the support member 30 Is made of a wire rope 131. The support member 30 is inserted into a hole formed in the slats 10 to support the slats 10, and is connected to a separate upper frame (not shown) to fold or unfold the slats 10. It will function.

FIG. 2 is a cross-sectional view illustrating the slat shown in FIG. 1.

Referring to the drawings, the slat 10 according to the present embodiment includes a main plate member 11, an auxiliary plate member 15 inserted into the main plate member 11, a main plate member 11 and an auxiliary plate. And a connecting member 17 for connecting the member 15.

In the above, the main plate member 11 is formed as a flat type having a predetermined width and length as shown in the figure. However, the present invention is not limited thereto and may be applied to all types of slats such as C-TYPE (curved type) or Z-TYPE (zigag type).

In this case, the main plate member 11 is made of a metal material having good thermal conductivity while having a predetermined thickness, and is supported by the supporting member 30 mentioned above and spaced apart at regular intervals along the vertical direction (FIG. 1).

The main plate member 11 is provided with an insertion groove 13 to form an opening on one side edge side along the longitudinal direction, the insertion groove 13 is formed to a predetermined depth in the width direction of the main plate member 11 do.

In the present embodiment, the auxiliary plate member 15 is a plate forming a coupling form with the insertion groove 13 of the main plate member 11, made of metal, plastic or wood, the insertion of the main plate member 11 While being inserted into the groove 13, it is slidably installed along the insertion groove 13 in the width direction of the main plate member (11).

The auxiliary plate member 15 is reciprocally slid in the width direction of the main plate member 11 along the insertion groove 13 of the main plate member 11 by the connecting member 17 to be described later in the insertion groove ( Protrudes or immerses through the opening in 13).

Therefore, the slats 10 according to the present embodiment are horizontally protruded or immersed through the opening of the insertion groove 13 while the auxiliary plate member 15 is inserted into the insertion groove 13 of the main plate member 11. The length (width full length) can be varied in the direction.

In the present embodiment, the connecting member 17 connects the main plate member 11 and the auxiliary plate member 15 in the insertion groove 13 of the main plate member 11, and the main plate member 11. Supporting the auxiliary plate member 15 with respect to the shape of the change as the temperature changes as well as the function to protrude or immerse the auxiliary plate member 15 through the opening of the insertion groove (13).

The connecting member 17 has a form bent in a zigzag and one end is connected to the main plate member 11 and the other end is connected to the auxiliary plate member 15, the deformation and restoration of the shape according to the temperature change It is made of a shape memory alloy material with this repeating property.

The shape memory alloy is made of a titanium-nickel alloy or an aluminum alloy, and has a property of restoring to its original shape when the plastic-deformed material is heated above a critical point of the material.

In this case, the connecting member 17 according to the present embodiment receives the heat and is elongated as a predetermined length when the main plate member 11 is heated above the critical point by solar radiation or outside air, and is cooled down below the critical point. The case is characterized by a restoration to its original form before being stretched.

Referring to the operation of the sunshade 100 according to the first embodiment of the present invention configured as described above, first, the slats 10 are arranged in the horizontal direction with respect to the glass window, supported by the support member 30 While being spaced apart at regular intervals along the vertical direction. At this time, the spacing of the slats 10 is appropriate enough to secure a view of the outdoors through the space between them.

In this case, the slats 10 are in a state where the auxiliary plate member 15 is immersed in the insertion groove 13 of the main plate member 11 as shown in FIG. 3A. In this case, the full width of the slat 10 is indicated by "L".

In this state, when the altitude of the sun increases, the distance from which the solar radiation energy reaches the atmosphere is shortened, so that the intensity of the solar radiation increases or the outside temperature rises, the temperature of the main plate member 11 gradually rises. Then, since the connecting member 17 is made of a shape memory alloy material, it is stretched in the shape of the original molding while being heated above the critical point by receiving the above heat.

Accordingly, the auxiliary plate member 15 slides along the insertion groove 13 of the main plate member 11 by the tension of the connecting member 17 as shown in FIG. 3B to open the opening of the insertion groove 13. Through it will be partly projected to the outside. As a result, the slat 10 extends as the width full length L in which the width full length L of the main plate member 11 and the protruding length of the auxiliary plate member 15 are added together.

Conversely, when the solar intensity is small or the outside air temperature drops, the connecting member 17 is restored to its original shape before being stretched at a temperature below the critical point. Then, the auxiliary plate member 15 is slid into the insertion groove 13 while sliding along the insertion groove 13 of the main plate member 11 by the contracting force of the connecting member 17. Therefore, the overall width full length l of the slat 10 is smaller than the width full length L when the connecting member 17 is stretched.

As described above, according to the sunshade device 100 according to the present embodiment, the shape and length of the connection member 17 are deformed according to the altitude of the sun or the temperature change of the outside air, whereby the auxiliary plate member 15 is the main plate. Protruding or immersed through the insertion groove 13 of the member 11, the width of the slat 10 is variable, it is possible to adjust the amount of solar radiation flowing into the room through the glass window without relying on a separate driving force. That is, in the case of summer when the solar radiation is large, the width of the slat 10 is increased by the above-described action to reduce the amount of solar radiation flowing into the room, and in the case of the winter when the outside temperature is low, the width of the slat 10 is reduced. This increases the amount of solar radiation that enters the room.

Referring to the drawings, the sunshade device 200 according to the present embodiment includes a plurality of slats 110 having a main plate member 111 and an auxiliary plate member 115 inserted into the main plate member 111. A support member 130 for supporting the slats 110 at a predetermined interval, a moving member 150 installed to be connected to each auxiliary plate member 115, and a bias installed to be connected to the moving member 150. It is configured to include a member 170.

The slats 110 are disposed in the horizontal direction with respect to the glass window as in the previous embodiment, and are spaced apart by a predetermined distance along the vertical direction while being supported by the support member 130.

The supporting member 130 is for adjusting the spacing between the slats 110 while supporting the slats 110, and more specifically, is installed to be connected to both side edge portions of the main plate member 111. The support member 130 is made of a wire rope 131. The support member 130 is inserted into a hole formed in the main plate member 111 to support the main plate members 111, and is connected to a separate upper frame (not shown in the drawing), and thus the main plate members ( 111) to fold or unfold.

The main plate member 111 has an insertion groove 113 forming an opening at one side edge side along its longitudinal direction, and the auxiliary plate member 115 is inserted into the insertion groove 113 of the main plate member 111. While being inserted, it is slidably installed along the insertion groove 113 in the width direction of the main plate member 111. Since the configuration of the main plate member 111 and the auxiliary plate member 115 is the same as in the previous embodiment, a detailed description thereof will be omitted.

In the present embodiment, the movable member 150 is installed to be connected to each auxiliary plate member 115 while being supported by a predetermined fixture 190, preferably an upper frame, in the width direction of the main plate member 111. It is installed to reciprocate. The movable member 150 is formed as a block shape that is supported by the fixing body 190 and reciprocally slidably coupled to the fixing body 190. In this case, the movable member 150 and each auxiliary plate member 115 is preferably connected as a wire rope 161.

In the present embodiment, the bias member 170 is to connect the moving member 150 and the stationary body 190, it is made as a structure that deforms in accordance with the temperature change.

The bias member 170 is bent in a zigzag form while one end is connected to the moving member 150 and the other end is connected to the fixture 190 so that deformation and restoration of the shape are repeated according to temperature change. It is formed as a shape memory alloy material with properties.

In this case, the bias member 170 according to the present embodiment moves the movable member 150 while being stretched to a predetermined length when heated above the critical point by solar radiation or outside air, and before being stretched when the bias member 170 is cooled below the critical point. It is restored to its original form and has a function of repositioning the movable member 150.

Referring to the operation of the sunshade device 200 according to the second embodiment of the present invention configured as described above, as the altitude of the sun increases, the distance the solar radiation energy reaches the atmosphere is shortened to increase the solar intensity or the outside temperature When is raised, the bias member 170 is stretched to the shape of the original molding while being heated above the critical point. Then, the moving member 150 is moved in one direction by the tensile force of the bias member 170.

Therefore, since each auxiliary plate member 115 is connected to the moving member 150 through the wire rope 161, the insertion groove 113 of the main plate member 111 as the moving member 150 is moved. Sliding along it is to protrude outward through the opening of the insertion groove 113. As a result, the slat 110 is extended as the total length of the width of the main plate member 111 and the protruding length of the auxiliary plate member 115.

On the contrary, when the solar intensity decreases gradually or the outside air temperature decreases, the bias member 170 is restored to its original shape before being stretched at a temperature below the critical point. Then, the movable member 150 is moved in the other direction by the contracting force of the bias member 170.

Therefore, each auxiliary plate member 115 is inserted into the insertion groove 113 while sliding along the insertion groove 113 of the main plate member 111. Therefore, the overall width of the slat 110 is smaller than the width of the full length when the biasing member 170 is stretched.

Although the preferred embodiments of the present invention have been described above, the present invention is not limited thereto, and various modifications and changes can be made within the scope of the claims and the detailed description of the invention and the accompanying drawings. Naturally, it belongs to the scope of the invention.

According to the present invention as described above, since the shape memory alloy is used as a structure for varying the width of the slat width field according to the outdoor weather conditions or the solar intensity (solar altitude, insolation angle), the amount of insolation flowing into the room is simple. It can be easily adjusted as a structure. Therefore, the heating and cooling load through the glass can be reduced, thereby contributing to energy saving, and it is possible to block direct solar radiation flowing into the room while securing an outdoor view, thereby improving the light environment of the room.

In addition, according to the present invention, there is no need for a manual operation or a separate drive device, the structure of the entire device is simplified, there is an effect that can reduce the manufacturing cost.
