Description

  The present invention relates to a blind installed on a window surface, and more particularly to a blind capable of guiding outside light into a room and brightening the room.

  Conventionally, there has been a blind for shielding sunlight (sunlight) from the outdoors during the day. As is well known, for example, a horizontal type blind is one in which a large number of slats (blades) are arranged side by side in the horizontal direction and the rotation angle of the slats is changed to mainly block sunlight. Has been proposed that has the function of reflecting the sunlight from the outside to the indoor ceiling, etc., and collecting the sunlight indoors while preventing direct penetration of sunlight. (For example, refer to Patent Document 1).

  Further, there has been proposed a daylighting blind including an upper slat portion having a mirror-like reflective surface that is concave upward and a plurality of lower slat portions having a convex irregular reflection surface on the upper side (see, for example, Patent Document 2). In this daylighting blind, the upper concave surface of the upper slat portion disposed in the upper part of the blind is designed to introduce external light into the room, and is disposed in the lower part of the blind. The lower slat part is shielded from light including the blindfold, which is the original function of the blind.

  However, the conventional blinds as described above are usually attached to the window frame. However, when the window is opened, the wind from the window hits the blind. Especially when a strong wind blows, many blind slats are generated. There have been problems such as vibrations caused by strong winds, resonance, and flapping and noise, and sometimes slats may be displaced or bent and deformed.

  The present invention solves the above-mentioned problems, and its purpose is to be able to collect sunlight from the outside indoors, increase the strength of the slats, and reduce the wind resistance during the opening of the windows. It is to provide a blind that can.

  In order to achieve the above object, the blind of the present invention is a blind composed of a plurality of slats, and at least one of the slats is a mirror surface and has a substantially S-shaped cross section. Features. According to the present invention, since the slat has a mirror surface, sunlight from the outdoors reflected by the mirror surface is reflected on the wall surface of the room and can be taken indoors. In addition, since the cross section is substantially S-shaped, the strength of the slats can be increased and the wind resistance at the time of opening the windows can be reduced.

  In the said aspect, it is preferable that a blind is a horizontal type and the upper surface of the slat arranged horizontally is a mirror surface. Thereby, in the horizontal blind, sunlight from the outside can be reflected on the ceiling of the room by the mirror surface on the upper surface of the slat and can be taken indoors.

  In the above aspect, the substantially S-shaped cross section of the slat is preferably a shape configured by combining a downwardly protruding slat body piece and an upwardly protruding slat body piece in the short direction. Thereby, in the horizontal blind, the slat strength is increased, and the blind that reduces the wind resistance at the time of opening the window is obtained.

  In the said aspect, a slat can be made into the mirror surface by the mirror surface film having been affixed. Moreover, in the said aspect, a slat can be made into the mirror surface by the coating or plating process or stainless steel processing by which surface glossy finish was carried out. Thereby, the upper surface of a slat can be easily made into a mirror surface.

  According to the blind of the present invention, since the slat has a mirror surface, sunlight from the outdoors reflected by the mirror surface can be reflected on the indoor wall surface and the like, and can be taken into the room, and the slat has a substantially S-shaped cross section. As a result, the strength of the slats can be increased, and the wind resistance at the time of opening can be reduced.

1 is a perspective view of a blind according to an embodiment of the present invention. It is explanatory drawing of the slat which comprises the blind shown in FIG. It is principal part sectional drawing of the blind shown in FIG.

  Hereinafter, an embodiment of the present invention will be described in detail with reference to the accompanying drawings. Note that the components in the embodiment of the present invention can be appropriately replaced with existing components and the like, and various variations including combinations with other existing components are possible. Therefore, the description of the embodiment of the present invention does not limit the contents of the device described in the claims of the registration of the utility model.

  FIG. 1 shows a perspective view of a blind 10 of the present invention. As shown in FIG. 1, the blind 10 is a horizontal type and includes a large number of slats 20 arranged in parallel. On both sides of the blind 10, a lifting string 4 for lifting the slat 20 is provided, and on one side of the blind 10, an angle adjusting bar 5 for adjusting the angle of the slat 20 is provided.

  FIG. 2 shows a structure of one slat 20 constituting the blind 10. The slat 20 has a mirror surface M that reflects light by attaching a mirror film 3 whose surface is made of a highly reflective film to the upper surface of the main body 2. Moreover, as shown in FIG. 2, the slat main body 2 has a shape formed by combining a slat main body piece 2A having a same width and the same shape, and a slat main body piece 2B having a convex shape in the short direction. It is formed into a S-shaped cross section.

  The material of the slat body 2 is aluminum, but it is possible to apply a material made of a moldable material such as a resin molded product, waterproof paper, wood, bamboo or the like.

  FIG. 3 is a cross-sectional view of a main part of the blind 10 shown in FIG. As described above, by making the upper surface of the slat 20 the mirror surface M, as shown in FIG. 3, the sunlight L from the outdoors is reflected by the mirror surface M as shown in FIG. (Not shown) can be brightly illuminated. As a result, energy can be saved as an alternative to daytime indoor lighting.

  Moreover, by making the cross-sectional shape of the slat 20 into an S-shape that is configured by combining the downwardly convex slat body piece 2A and the upwardly convex slat body piece 2B in the short direction, The strength of the slat 20 against bending in the longitudinal direction is strengthened as compared with a slat having a shape composed of a slat that is simply convex downward or only a slat that is convex upward.

  Further, by making the cross section of the slat 20 into an S shape, the flow of wind hitting the blind is dispersed in the vertical direction as compared with a blind in which only a downwardly convex slat or only an upwardly convex slat is horizontally arranged. Therefore, it becomes possible to reduce the wind resistance by diffusing the wind flow received during the opening of the window. This reduces the vibration or resonation of the slats 20 when the slats 20 are swung, particularly in strong winds, and the slats 20 are less likely to be displaced or bent and deformed.

  The blind according to the present invention is not limited to the above-described embodiment, and can of course have various configurations without departing from the gist of the present invention. For example, the slat may have a combination of slat body pieces 2A and 2B having the same width and the same shape as shown in FIG. The width of the slat main body pieces may be the same, and the cross section may be formed in a substantially S shape by appropriately combining deep or shallow curved surfaces of the convex portions or convex portions of the slat main body pieces.

  In addition, not all of the many slats 20 of the blind 10 are formed with a cross-section formed into an S-shape, but a part of the slats of a slat having a conventional cross-sectional shape (for example, a mirror surface having a concave surface) is formed. An upper slat having a reflecting surface may be used.

  Further, as a method of making the upper surface of the slat 20 a mirror surface, a method of making the surface mirror-finished by painting with a glossy surface or a method of making the surface mirror-finished by a plating process such as chrome plating may be used. You may form by the stainless steel processing made high.

  The blind according to the present invention is useful as a blind that can guide outside light into the room and brightly illuminate the room.
